    (ar_name_equal): #if 0 truncating code.

    * make.h: Don't declare vfork at all.  It returns int anyway,
    unless <unistd.h> declared it; and we conflicted with some systems.

    * main.c (define_makeflags): If FLAGSTRING[1] is '-', define
    MAKEFLAGS to all of FLAGSTRING, not &FLAGSTRING[1].  Don't want to
    define it to something like "-no-print-directory".
    Use %g format instead of %f for floating-valued things.

Thu Apr 22 18:40:58 1993  Roland McGrath  ([e-mail])

    * GNUmakefile (Makefile.in): Use a substitution ref on nolib-deps
    to change remote-%.dep to remote-stub.dep.

Wed Apr 21 15:17:54 1993  Roland McGrath  ([e-mail])

    * Version 3.64.

Fri Apr 16 14:22:22 1993  Roland McGrath  ([e-mail])

    * compatMakefile (install): Remove - prefix from chgrp+chmod.

    * Version 3.63.8.

Thu Apr 15 18:24:07 1993  Roland McGrath  ([e-mail])

    * acconfig.h: New file; contains "#undef SCCS_GET" for autoheader.
    * configure.in: If /usr/sccs/get exists, define SCCS_GET to that,
    else to "get".
    * default.c (default_variables): Set GET to macro SCCS_GET.

    * read.c (parse_file_seq): Take extra arg STRIP; strip `./' only
    if nonzero.  I hope this is the last time this argument is added
    or removed.
    (read_makefile): Pass it 1 when parsing include file names.
    Pass it 1 when parsing target file names.
    Pass it 1 when parsing static pattern target pattern names.
    * rule.c (install_pattern_rule): Pass it 1 when parsing rule deps.
    * default.c (set_default_suffixes): Pass it 1 when parsing
    default_suffixes.
    * function.c (string_glob): Pass it 0 here.

Wed Apr 14 11:32:05 1993  Roland McGrath  ([e-mail])

    * misc.c (log_access): New function.
    ({init,user,make,child}_access): Call it.
    (child_access): Abort if !access_inited.

    * main.c (switches: --no-print-directory): Use 1 instead of -1 for
    single-letter option.
    (init_switches, decode_switches, define_makeflags): An option with
    no single-letter version is no longer indicated by a value of -1;
    instead a value that is !isalnum.
    (init_switches): Don't put such switches into the string, only
    into the long_option table.

    * make.h [!NSIG] [!_NSIG]: #define NSIG 32.

    * job.c [HAVE_WAITPID]: Remove #undef HAVE_UNION_WAIT.  AIX's
    bsdcc defined WIF* to use union wait.

    * main.c (struct command_switch): Change member `c' to type int.
    (switches): Make const.
    (decode_switches): Use `const struct command_switch *'.
    (define_makeflags): Likewise.

    * default.c (default_suffix_rules): Add `-o $@' to makeinfo rules.

Mon Apr 12 12:30:04 1993  Roland McGrath  ([e-mail])

    * Version 3.63.7.

    * configure.in (AC_HAVE_HEADERS): Check for string.h and memory.h.
    Removed AC_MEMORY_H.
    * make.h [USG, NeXT]: Don't test these.
    [HAVE_STRING_H]: Test this to include string.h and define ANSI_STRING.
    [HAVE_MEMORY_H]: Test this instead of NEED_MEMORY_H.
    [! ANSI_STRING]: Put decls of bcopy et al here.
    [sparc]: Don't test this for alloca.h; HAVE_ALLOCA_H is sufficient.
    [HAVE_SIGSETMASK]: Test this rather than USG.
    [__GNU_LIBRARY__ || POSIX]: Don't #include <unistd.h> again.
    * main.c (main): Handle SIGCHLD if defined, and SIGCLD if defined.
    It doesn't hurt to do both if they are both defined, and testing
    USG is useless.
    * dir.c: Rationalize directory header conditionals.
    * arscan.c [HAVE_FCNTL_H]: Test this rather than USG || POSIX.

    * default.c (default_suffixes): Add `.txinfo'.
    (default_suffix_rules): Add `.txinfo.info' and `.txinfo.dvi' rules.

    * variable.c (try_variable_definition): Replace RECURSIVE flag
    with enum FLAVOR, which can be simple, recursive, or append.
    Recognize += as append flavor.  Set new variable VALUE in a switch
    on FLAVOR.  For append flavor, prepend the variable's old value.
    If the variable was previously defined recursive, set FLAVOR to
    recursive; if it was defined simple, expand the new value before
    appending it to the old value.  Pass RECURSIVE flag to
    define_variable iff FLAVOR == recursive.

    * variable.c (try_variable_definition): Use alloca and bcopy for
    NAME, instead of savestring.  Might as well use stack storage
    since we free it immediately anyway.

Thu Apr  8 18:04:43 1993  Roland McGrath  ([e-mail])

    * job.c (start_waiting_jobs): Move decl of JOB outside of loop.

    * main.c (define_makeflags): Rename `struct flag' member `switch'
    to `cs', which is not a reserved word.

Wed Apr  7 15:30:51 1993  Roland McGrath  ([e-mail])

    * job.c (new_job): Call start_waiting_jobs first thing.
    (start_waiting_job): Changed return type from void to int.
    Return 0 when putting the child on the waiting_jobs chain.
    (start_waiting_jobs): Don't check load and job_slots here.
    Always take a job off the chain and call start_waiting_job on it;
    give up and return when start_waiting_job returns zero.

    * main.c (define_makeflags: struct flag): Change member `char c' to
    `struct command_switch *switch'.
    (ADD_FLAG): Set that to CS instead of CS->c.
    If CS->c is -1, increment FLAGSLEN for the long name.
    When writing out FLAGS, handle FLAGS->switch->c == -1 and write
    the long name instead.

    * compatMakefile (stamp-config): New target of old config.h rule.
    Touch stamp-config after running config.status.
    (config.h): Just depend on stamp-config, and have empty commands.

Mon Apr  5 20:14:02 1993  Roland McGrath  ([e-mail])

    * job.c [HAVE_WAITPID]: #undef HAVE_UNION_WAIT.

    * configure.in (AC_HAVE_FUNCS): Check for psignal.

Fri Apr  2 17:15:46 1993  Roland McGrath  ([e-mail])

    * main.c (long_option_aliases): Remove "new"; it is already an
    unambiguous prefix of "new-file".

Sun Mar 28 16:57:17 1993  Roland McGrath  ([e-mail])

    * Version 3.63.6.

Wed Mar 24 14:26:19 1993  Roland McGrath  ([e-mail])

    * vpath.c (selective_vpath_search): When adding the
    name-within-directory at the end of NAME, and we don't add a
    slash, don't copy FILENAME in one char too far into NAME.

    * variable.c (define_automatic_variables): Find default_shell's
    length with strlen, not numerology.

Wed Mar 17 20:02:27 1993  Roland McGrath  ([e-mail])

    * main.c (define_makeflags): Add the elts of a string option in
    reverse order, so they come out right when reversed again.

Fri Mar 12 15:38:45 1993  Roland McGrath  ([e-mail])

    * compatMakefile (make.info): Use `-o make.info'.

Thu Mar 11 14:13:00 1993  Roland McGrath  ([e-mail])

    * compatMakefile (REMOTE): Set to @REMOTE@; change comments to
    reflect new use.
    (objs): Replace remote.o with remote-$(REMOTE).o.
    (srcs): Replace remote.c with remote-$(REMOTE).c.
    (remote.o): Rule removed.

    * configure.in (REMOTE): Subst this in Makefile et al; default "stub".
    Use AC_WITH to grok --with-customs arg to set REMOTE=cstms.
    * GNUmakefile (build.sh.in): Filter out remote-% from objs list.
    * build.template (REMOTE): New var; set to @REMOTE@.
    (objs): Add remote-${REMOTE}.o.

Wed Mar 10 15:12:24 1993  Roland McGrath  ([e-mail])

    * Version 3.63.5.

    * implicit.c (pattern_search): Fix "dependent"->"dependency" in
    "Rejecting impossible" -d msg.

    * file.c (file_hash_enter): New local vars {OLD,NEW}BUCKET.  Store
    mod'd values there; never mod {OLD,NEW}HASH.

Mon Mar  8 13:32:48 1993  Roland McGrath  ([e-mail])

    * remake.c [eta10]: Include <fcntl.h> instead of <sys/file.h>.

    * compatMakefile (VPATH): Set this to @srcdir@.
    (srcdir): Set this to $(VPATH).

    * main.c (main): New local var DIRECTORY_BEFORE_CHDIR.  Save in it
    a copy of CURRENT_DIRECTORY after the first getcwd.  Use it
    instead of CURRENT_DIRECTORY when chdir'ing back before re-execing.

    * remake.c (notice_finished_file): Pass missing SEARCH arg to f_mtime.

    * read.c (read_makefile): Remove extraneous arg to parse_file_seq.

Mon Feb 22 14:19:38 1993  Roland McGrath  ([e-mail])

    * compatMakefile ($(infodir)/$(instname).info): Use , instead of /
    as the sed delimiter char.

Sun Feb 21 14:11:04 1993  Roland McGrath  ([e-mail])

    * Version 3.63.4.

    * rule.h (struct rule): Removed `subdir' member.
    * rule.c (new_pattern_rule): No need to clear it.
    (count_implicit_rule_limits): Set the `changed' flag in each dep
    that refers to a nonexistent directory.  No longer set rule-global
    `subdir' flag with that information.
    (print_rule_data_base): Don't record info on `subdir' flags.

    * implicit.c (pattern_search): Check the DEP->changed flag rather
    than the (now gone) RULE->subdir flag.  Also test CHECK_LASTSLASH;
    if it is set, the file might exist even though the DEP->changed
    flag is set.

    * rule.c (count_implicit_rule_limits): Pass "", not ".", as file
    name arg to dir_file_exists_p to check for existence of directory.

    * implicit.c (pattern_search): Inside dep-finding loop, set
    CHECK_LASTSLASH from the value recorded in CHECKED_LASTSLASH[I],
    rather than computing it anew.

    * commands.c (set_file_variables): Must alloca space for PERCENT
    and copy it, to avoid leaving the trailing `)' in the value.

    * misc.c (remove_comments): Fixed backslash-checking loop
    condition to allow it to look at the first char on the line.
    P2 >= LINE, not P2 > LINE.

    * compatMakefile ($(bindir)/$(instname)): Before moving $@.new to
    $@, rm $@.old and mv $@ to $@.old.

    * variable.c (try_variable_definition): Take new args FILENAME and
    LINENO.  Fatal if the variable name is empty.
    * read.c (read_makefile): Change callers.
    * main.c (main): Likewise.

    * compatMakefile (group): Define to @KMEM_GROUP@, autoconf magic
    that configure will replace with the group owning /dev/kmem.

Mon Feb  8 14:26:43 1993  Roland McGrath  ([e-mail])

    * vpath.c (vpath_search): Take second arg MTIME_PTR, pass thru to
    selective_vpath_search.
    (selective_vpath_search): Take second arg MTIME_PTR.
    If the dir cache thinks a file exists, stat it to make sure, and
    put the modtime in *MTIME_PTR.
    * remake.c (library_search): Take second arg MTIME_PTR.
    When we find a match, record its mtime there.
    Pass MTIME_PTR through to vpath_search to do same.
    (f_mtime): Pass &MTIME as new 2nd arg to {vpath,library}_search;
    store it in FILE->last_mtime if set nonzero.
    * implicit.c (pattern_search): Pass nil 2nd arg to vpath_search.

    * compatMakefile (remote.o): Prepend `$(srcdir)/' to `remote-*.c',
    so globbing looks somewhere it will find things.

    * compatMakefile ($(infodir)/$(instname).info): Install `make.info*'
    not `$(srcdir)/make.info*'; no need to use basename.

Fri Feb  5 12:52:43 1993  Roland McGrath  ([e-mail])

    * Version 3.63.3.

    * compatMakefile (install): Add missing ;\s.

    Make -, @, and + prefixes on a pre-expanded command line affect
    all lines in the expansion, not just the first.
    * commands.h (struct commands): Replace `lines_recurse' member
    with `lines_flags'.
    (COMMANDS_{RECURSE,SILENT,NOERROR}): New macros, bits to set in
    that flag byte.
    * commands.c (chop_commands): Set `lines_flags' instead of
    `lines_recurse'.  Record not only + but also @ and - prefixes.
    * remake.c (notice_finished_file): Check the COMMANDS_RECURSE bit
    in FILE->cmds->lines_flags, rather than FILE->cmds->lines_recurse.
    * job.c (start_job_command): Replaced RECURSIVE and NOPRINT local
    var with FLAGS; initialize it to the appropriate `lines_flags' byte.
    Set CHILD->noerror if the COMMANDS_NOERROR bit is set in FLAGS.
    Set the COMMANDS_SILENT bit in FLAGS for a @ prefix.

    * remake.c (update_goal_chain): Set G->file to its prev after
    checking for G being finished, since that check needs to examine
    G->file.

    * configure.in (union wait check) [HAVE_WAITPID]: Try using
    waitpid with a `union wait' STATUS arg.  If waitpid and union wait
    don't work together, we should not use union wait.

    * Version 3.63.2.

    * remake.c (update_goal_chain): When G->file->updated, move
    G->file to its prev.  We aren't finished until G->file is nil.

Thu Feb  4 12:53:04 1993  Roland McGrath  ([e-mail])

    * main.c (starting_directory): New global variable.
    (main): Set it to cwd after doing -Cs.
    (log_working_directory): Use it, rather than computing each time.
    * make.h: Declare it.

    * compatMakefile (SHELL): Define to /bin/sh for losing Unix makes.

    * main.c (decode_env_switches): Allocate (1 + LEN + 1) words for
    ARGV, rather than LEN words plus one byte.

Wed Feb  3 18:13:52 1993  Roland McGrath  ([e-mail])

    * compatMakefile ($(bindir)/$(instname)): Put - before
    install_setgid command line, so its failure won't be an error.
    (infodir): New variable.
    (install): Depend on $(infodir)/$(instname).info.
    ($(infodir)/$(instname).info): New target.

    * read.c (read_makefile): If FILENAMES is nil when we see a line
    starting with a tab, don't treat it as a command.  Just fall
    through, rather than giving an error.

    * read.c (read_makefile): If the NO_TARGETS flag is set when we see a
    command line, don't clear it before continuing.  We want
    subsequent command lines to be ignored as well.

    * job.c (new_job): Before expanding each command line, collapse
    backslash-newline combinations that are inside var or fn references.

Mon Feb  1 16:00:13 1993  Roland McGrath  ([e-mail])

    * compatMakefile (exec_prefix): Default to $(prefix), not /usr/local.

    * compatMakefile (make.info): Pass -I$(srcdir) to makeinfo.

    * job.c [POSIX] (unblock_sigs): Made global.
    [!POSIX] (unblock_sigs): Move defns to job.h.
    * job.h [POSIX] (unblock_sigs): Declare.

Sun Jan 31 19:11:05 1993  Roland McGrath  ([e-mail])

    * read.c (read_makefile): In vpath parsing, after finding the
    pattern token, take entire rest of line as the search path, not
    just the next token.

    * compatMakefile (remote.o): Depend on remote-*.c.

Thu Jan 28 16:40:29 1993  Roland McGrath  ([e-mail])

    * commands.c (set_file_variables): Don't define any F or D versions.
    * variable.c (define_automatic_variables): Define them here as
    recursively-expanded variables that use the dir and notdir funcs.

    * variable.c (target_environment): In v_default case, don't export
    o_default or o_automatic variables.

    * configure.in (union wait check): Remove ` and ' inside C code;
    they confuse the shell script.

Mon Jan 25 13:10:42 1993  Roland McGrath  ([e-mail])

    * Version 3.63.1.

    * vpath.c (construct_vpath_list): When skipping further processing
    of an elt that is ".", don't also skip the code that pushes P past
    the next separator.

    * compatMakefile (distclean): Don't remove make-*.

    * configure.in (HAVE_UNION_WAIT): Try to use WEXITSTATUS if it's
    defined.  If one cannot use WEXITSTATUS with a `union wait'
    argument, we don't want to believe the system has `union wait' at all.

    * remake.c (update_file): Do nothing to print "up to date" msgs.
    (update_goal_chain): Do it here instead.
    Use the `changed' flag of each goal's `struct dep' to keep track
    of whether files_remade (now commands_started) changed around a
    call to update_file for that goal.
    When a goal is finished, and its file's update_status is zero (i.e.,
    success or nothing done), test the `changed' flag and give an "up
    to date" msg iff it is clear.
    * make.h (files_remade): Renamed to commands_started.
    * remake.c: Changed defn.
    (update_goal_chain): Changed uses.
    * job.c (start_job_command): Increment commands_started here.
    (reap_children): Not here.

    * remake.c (update_goal_chain): Don't do anything with files'
    `prev' members.  update_file now completely handles this.

    * variable.c (target_environment): Don't expand recursive
    variables if they came from the environment.

    * main.c (define_makeflags): For flags with omitted optional args,
    store {"", 0} with ADD_FLAG.  When constructing FLAGSTRING, a flag
    so stored cannot have more flags appended to the same word.

Fri Jan 22 14:46:16 1993  Roland McGrath  ([e-mail])

    * variable.c (print_variable_set): In vars/bucket calculation,
    don't spuriously multiply by 100.

    * Version 3.63.

    * job.c [!HAVE_UNION_WAIT] (WTERMSIG, WCOREDUMP, WEXITSTATUS):
    Don't define if already defined.

    * remake.c (update_file): Don't keep track of the command_state before
    calling update_file_1.  Remove local variable COMMANDS_FINISHED,
    and don't test it to decide to print the "is up to date" msg.
    Testing for files_remade having changed should always be sufficient.
    The old method lost when we are called in the goal chain run on a
    makefile, because the makefile's command_state is already
    `cs_finished' from the makefile chain run.

    * misc.c [HAVE_SETRE[GU]ID]: Test these to decl setre[gu]id.

    * configure.in: Rewrote wait checking.
    Use AC_HAVE_HEADERS to check for <sys/wait.h>.
    Use AC_HAVE_FUNCS to check for waitpid and wait3.
    Use a compile check to test just for `union wait'.
    * job.c: Rewrote conditionals accordingly.
    [HAVE_WAITPID]: Test this only to define WAIT_NOHANG.
    [HAVE_WAIT3]: Likewise.
    [HAVE_UNION_WAIT]: Test this to define WAIT_T and W*.

    * configure.in: Set CFLAGS and LDFLAGS before all checks.

    * dir.c: Add static forward decls of {open,read}_dirstream.

Thu Jan 21 17:18:00 1993  Roland McGrath  ([e-mail])

    * Version 3.62.31.

    * job.c [NGROUPS_MAX && NGROUPS_MAX==0]: #undef NGROUPS_MAX.

    * compatMakefile (CFLAGS, LDFLAGS): Set to @CFLAGS@/@LDFLAGS@.
    * build.template (CFLAGS, LDFLAGS): Same here.
    * configure.in: AC_SUBST(CFLAGS) and LDFLAGS.
    Set them to -g if not defined in the environment.

    * remake.c (library_search): Use LIBNAME consistently, setting it
    only once, to be the passed name sans `-l'.
    Pass new var FILE to be modified by vpath_search.

Mon Jan 18 14:53:54 1993  Roland McGrath  ([e-mail])

    * Version 3.62.30.

    * job.c (start_waiting_jobs): Return when job_slots_used is equal to
    job_slots.

    * configure.in: Add AC_CONST for the sake of getopt.

    * read.c (read_makefile): Continue after parsing `override'
    directive, rather than falling through to lossage.
    Check for EOL or blank after "override define".

    * compatMakefile (.c.o, remote.o): Put $(CFLAGS) after other switches.

Fri Jan 15 12:52:52 1993  Roland McGrath  ([e-mail])

    * Version 3.62.29.

    * main.c (define_makeflags): After writing everything into
    FLAGSTRING, only back up two chars if [-1] is a dash, meaning we
    just wrote " -".  Always terminate the string at *P.

    * remake.c (library_search): When constructing names in std dirs,
    use &(*LIB)[2] for the stem, not LIBNAME (which points at the
    buffer we are writing into!).

Thu Jan 14 13:50:06 1993  Roland McGrath  ([e-mail])

    * read.c (read_makefile): Set IN_IGNORED_DEFINE for "override
    define" when IGNORING is true.

    * compatMakefile (distclean): Remove config.status and build.sh.

Wed Jan 13 16:01:12 1993  Roland McGrath  ([e-mail])

    * Version 3.62.28.

    * misc.c (xmalloc, xrealloc): Cast result of malloc/realloc to
    (char *).

    * arscan.c (ar_scan) [AIAMAG]: Cast read arg to (char *).

    * variable.c (define_automatic_variables): Override SHELL value for
    origin o_env_override as well as o_env.

    * GNUmakefile (build.sh.in): Don't replace %globobjs%.  Instead,
    add the names of the glob objects (w/subdir) to %objs%.
    * build.template (globobjs): Removed.
    Take basename of $objs before linking.

Tue Jan 12 12:31:06 1993  Roland McGrath  ([e-mail])

    * Version 3.62.27.

    * configure.in (AC_OUTPUT): Also edit build.sh.
    * build.template: New file.
    * GNUmakefile (build.sh.in): New rule to create it from build.template.
    (make-$(version).tar.Z): Depend on build.sh.in.

    * main.c (die): Call print_data_base if -p.
    (main): Don't call it here.

    * compatMakefile (defines): Add @DEFS@.  configure should turn this
    into -DHAVE_CONFIG_H.

Mon Jan 11 14:39:23 1993  Roland McGrath  ([e-mail])

    * Version 3.62.26.

    * misc.c (init_access): Surround with #ifdef GETLOADAVG_PRIVILEGED.
    ({make,user,child}_access) [! GETLOADAVG_PRIVILEGED]: Make no-op.
    * compatMakefile (install_setgid): New var, set by configure.
    (install): Install setgid $(group) only if $(install_setgid) is true.

Fri Jan  8 15:31:55 1993  Roland McGrath  ([e-mail])

    * job.c (load_too_high): If getloadavg fails with errno==0, give a
    message saying that load limits are not supported.

    * vpath.c (construct_vpath_list): Rewrote path deletion code to
    not try to use PATH's next link after freeing PATH.

    * main.c (define_makeflags): Rewritten; now handles string-valued
    option, and has no arbitrary limits.
    (switches): Set `toenv' flag for -I and -v.

    * main.c (decode_env_switches): Cast return value of alloca to char *.

    * misc.c (child_access) [HAVE_SETREUID, HAVE_SETREGID]: Use
    setre[gu]id in place of set[gu]id.

Wed Jan  6 15:06:12 1993  Roland McGrath  ([e-mail])

    * main.c (main): Define MAKEOVERRIDES, MAKE, and MAKE_COMMAND with
    origin o_default.

    * make.h [POSIX]: Don't test this to use ANSI_STRING.
    Testing STDC_HEADERS should be sufficient.

    * job.h: Declare start_waiting_jobs.

    * read.c (read_makefile): Add missing parens in if stmt that find
    conditional directives.

    * main.c (main): Declare init_dir.

    the target partially made.

Tue May 12 00:39:19 1992  Roland McGrath  ([e-mail])

    * job.c (construct_command_argv_internal): After loop, if we only
    have one word, check it for being a shell command.

    * main.c (decode_switches): Allocate ARGC slots in other_args to
    begin with, so we never need to worry about growing it.
    If we get a non-option arg and POSIXLY_CORRECT is in the
    environment, break out of the loop.  After the loop, add all remaining
    args to other_args list.

    * main.c (decode_switches): For positive_int and floating switches
    when optarg is nil, use next arg if it looks right (start with a
    digit, or maybe decimal point for floating).

    Fixed loop to not ignore all the options.

    * make.texinfo (Option Summary): Added long options.

    * main.c (switches): Changed -m's description to "-b".
    (decode_switches): When printing the usage message, don't print

    Call -I --include-dir, not --include-path.

    * main.c (switches): Removed bogus "silent" elt.
    (long_option_aliases): Define new var.

    (child_handler): Increment dead_children instead of setting child_died.
    (reap_children): Decrement dead_children instead of clearing
    child_died.  The point of all this is to avoid printing "waiting
    for unfinished jobs" when we don't actually need to block.
    This happened when multiple SIGCHLDs before reap_children was called.

    * job.c (reap_children): If ERR is set, so we don't call start_job
    on the child being reaped, instead set its command_state to
    cs_finished.
    (reap_children, child_handler, new_job): I added several
    debugging printf's while fixing this.  I left them in if (debug_flag)
    because they may be useful for debugging this stuff again.

    renamed one of the files the dep chain points to.

    * file.c (rename_file): If FILE has been renamed, follow its
    `renamed' ptr, so we get to the final real FILE.  Using the renamed
    ones loses because they are not in the hash table, so the removal

    * job.c (construct_command_argv_internal): Quote backslashes
    when building the shell -c line.

Fri Mar  8 01:40:18 1991  Roland McGrath  (roland at geech.ai.mit.edu)

    * job.c (exec_command): Call user_access rather than setgid(getgid()).

    * misc.c (remove_comments): Renamed from collapse_line; took out
    collapse_continuations call.
    * make.h: Change decl.
    * read.c (read_makefile): Collapse continuations on the line buffer
    immediately after reading it.  Call remove_comments rather than
    collapse_line (which is now defunct).

Thu Feb 21 18:06:51 1991  Roland McGrath  (mcgrath at cygint.cygnus.com)

    * misc.c (user_access, make_access): New fns to toggle btwn permissions
    for user data (files and spawning children), and permissions for make
    (for taking the load average, mostly).
    * make.h: Declare them.

    user_access after.
    * main.c (main): Call user_access before doing much.

Mon Feb  3 15:02:03 1991  Roland McGrath  (roland at albert.ai.mit.edu)

    * Version 3.59.2.

Tue Jan 29 20:30:50 1991  Roland McGrath  (roland at cygint.cygnus.com)

    * read.c (read_all_makefiles): Use allocated_variable_expand to expand
    `$(MAKEFILES)', since the results are used across calls to
    read_makefile, which could clobber them.

Wed Jan 23 00:24:10 1991  Roland McGrath  (roland at cygint.cygnus.com)

    * main.c (main): Call install_default_implicit_rules after reading
    makefiles, not before.

    entry has cmds, don't give it any from default_suffix_rules.

Fri Jan 17 17:39:49 1991  Roland McGrath  (roland at albert.ai.mit.edu)

    * arscan.c: Added support for AIX archives.

    * job.c (search_path): Take new arg, place to put full pathname (rather
    than mallocing it).
    (exec_command): Pass it, using auto storage.

    * main.c (print_version): Updated copyright years.

Wed Jan  8 19:46:19 1991  Roland McGrath  (roland at albert.ai.mit.edu)

    * job.c [_POSIX_SOURCE]: Just #include <sys/wait.h>, and define macro
    WAIT_NOHANG in terms of waitpid.
    [!_POSIX_SOURCE && (HAVE_SYS_WAIT || !USG)]: Don't #include <signal.h>
    (make.h does).
    Define macro WAIT_NOHANG in terms of wait3.
    (child_handler): #ifdef on WAIT_NOHANG, not HAVE_SYS_WAIT || !USG.
    Use WAIT_NOHANG macro instead of wait3.

    * file.h (struct file.command_state): Remove unused elt.

Wed Dec 26 18:10:26 1990  Roland McGrath  (roland at albert.ai.mit.edu)

    * commands.c (set_file_variables): If FILE got its commands from
    .DEFAULT, make $< == $@ (4.3 BSD/POSIX.2d11 compat).

Mon Dec 24 17:36:27 1990  Roland McGrath  (roland at albert.ai.mit.edu)

    * default.c (default_variables): Rename 2nd LINK.s defn to LINK.S.

    * vpath.c (selective_vpath_search): Check for makefile-mentioned before
    checking for actual existence.  The old order loses if the containing
    directory doesn't exist (but a rule might make it).

    * make.h [__GNUC__]: Don't #define alloca if already #define'd.

    * rule.c (convert_to_pattern): Don't look at the target constructed for
    the empty rule when making the null-suffix rule.  Construct it over
    again, since the former may have been freed already.

Thu Dec 13 17:21:03 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * make.h [__GNU_LIBRARY__]: Include <unistd.h> to get random fn decls.

Wed Dec 12 17:12:59 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * make.h, arscan.c, glob.c: Only include <memory.h> #ifdef USG.

    * variable.c (define_variable_in_set): Replace env_overrides check that
    wasn't really redundant (undoing Sep 28 change).  Add comment saying
    why this check is necessary.

    * job.c, main.c [DGUX]: Needs siglist like USG.

Mon Dec 11 01:19:29 1990  Roland McGrath  (roland at albert.ai.mit.edu)

    * default.c [M_XENIX]: For rules that are different for Xenix, use the
    generic Unix version #ifdef __GNUC__.

    * main.c [M_XENIX]: Use USGr3-style setvbuf call.

    * read.c (find_percent): Do backslash folding correctly, not leaving
    extra crud on the end of the string.

Sun Dec 10 21:48:36 1990  Roland McGrath  (roland at albert.ai.mit.edu)

    * job.c: Don't declare wait3 if it's #defined.

    * GNUmakefile, compatMakefile, make.texinfo: Change make-info
    to make.info.

Thu Dec  7 21:20:01 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * make.h [STDC_HEADERS || __GNU_LIBRARY__ || _POSIX_SOURCE]: Use
    ANSI <string.h> and names for str/mem functions.
    Use <stdlib.h> to declare misc fns rather than explicit decls.
    [_POSIX_SOURCE]: Don't declare kill (<signal.h> will).
    Include <sys/types.h> before <signal.h> because some braindead
    nonconformant 1003.1 implementation needs it.
    * misc.c: Don't declare malloc, realloc.  Do it in make.h.
    * arscan.c, glob.c: Use sequence for string fns from make.h verbatim.
    * make.h (S_ISDIR, S_ISREG): Declare if necessary.
    * commands.c (delete_child_targets), job.c (search_path), read.c
    (construct_include_path): Use S_ISfoo(m) instead of
    (m & S_IFMT) == S_IFfoo.
    * dir.c, glob.c [_POSIX_SOURCE]: Use dirent.

Wed Nov 29 22:53:32 1990  Roland McGrath  (roland at geech.ai.mit.edu)

    * Version 3.59.

Tue Nov 28 16:00:04 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * arscan.c (ar_name_equal) [APOLLO]: Don't do `.o' hacking.  On Apollos
    the full file name is elsewhere, and there is no length restriction (or
    so I'm told).

    symlinks), to grab texinfo.tex from wherever it lives.

Tue Oct 30 16:15:20 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * Version 3.58.13.

Fri Oct 26 14:33:34 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * GNUmakefile: make-*.tar.Z: Include texinfo.tex.

Tue Oct 23 19:34:33 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * main.c (define_makeflags): When there are no flags to write, make
    sure the array has two leading nulls, since `MAKEFLAGS' is defined from
    &flags[1].

    * main.c (default_keep_going_flag): New variable (constant one).
    (command_switches: -k, -S): Use above for default value.
    (define_makeflags): Only write flag/flag_off switches if they are on,
    and either there is no default value, or they are not the default.

Mon Oct 22 16:14:44 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * main.c (struct command_switch): New member `no_makefile'.
    (command_switches: -n, -q, -t): Set no_makefile == 1.
    (define_makeflags): Take new arg MAKEFILE: if nonzero, don't use
    options whose `no_makefile' flags are set.
    (main): Call define_makeflags with MAKEFILE==1 before remaking
    makefiles, and again with MAKEFILE==0 before remaking goals.

Tue Oct  2 17:16:45 1990  Roland McGrath  (roland at geech.ai.mit.edu)

    * Version 3.58.12.

Mon Oct  1 15:43:23 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * arscan.c [HPUX]: Use PORTAR==1 format.

Sat Sep 29 16:38:05 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * make.h, remake.c, arscan.c: Don't declare `open'.

Fri Sep 28 04:46:23 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * variable.c (define_variable_in_set): Remove redundant -e check.

Wed Sep 26 00:28:59 1990  Roland McGrath  (roland at geech.ai.mit.edu)

    * job.c (start_job): Set RECURSIVE from the right elt of
    CHILD->file->cmds->lines_recurse.

    * commands.c (chop_commands): Don't botch the line count for allocating
    CMDS->lines_recurse.

    * Version 3.58.11.

    * job.c (start_job): Don't always increment CHILD->command_line!  Only
    do it when CHILD->command_ptr has run out!  (Dumb bug.  Sigh.)

Thu Sep 20 02:18:51 1990  Roland McGrath  (roland at geech.ai.mit.edu)

    * GNUmakefile [ARCH]: Give explicit rule for remote.{c,dep} to use
    variable `REMOTE' for more flags.
    ($(prog)): Link in $(LOADLIBES).

Wed Sep 19 02:30:36 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * commands.h (struct commands): New member `ncommand_lines', the number
    of elts in `command_lines' et al.
    * commands.c (chop_commands): Set `ncommand_lines' elt of CMDS, and
    don't put a nil pointer at the end of `command_lines'.
    * job.h (struct child): New member `command_lines' to hold
    variable-expanded command lines.
    * job.c (new_job): Store expanded command lines in `command_lines'
    member of new child.  Don't clobber FILE->cmds.
    (start_job): Use CHILD->command_lines in place of
    CHILD->file->cmds->command_lines.

    * variable.h, variable.c, job.c, expand.c: Undo yesterday's change,
    which is no longer necessary since we have cleverly avoided the issue.

    * job.c (start_job): Don't variable-expand each command line.
    (new_job): Do them all here, storing the expansions in the array.

Tue Sep 18 01:23:13 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * variable.h (struct variable): Remove `expanding' member.
    * variable.c (define_variable_in_set): Don't initialize it.
    * expand.c (struct variable_expanding): New type, a linked list
    containing `struct variable' pointers.
    (variables_expanding): New variable, the chain of variables currently
    being expanded.
    (recursively_expand): Don't test and set `expanding' member.
    Instead, run through the `variables_expanding' chain looking for a link
    referring to V to find self-reference.  Add a new link to the chain,
    describing V, before recursive expansion, and pop it off afterward.
    * job.c (child_handler): Save `variables_expanding' and clear it before
    calling start_job, and restore it afterward.  This avoids major lossage
    when the SIGCHLD comes in the middle of variable expansion.

Mon Sep 17 14:46:26 1990  Roland McGrath  (roland at geech.ai.mit.edu)

    * job.c, commands.c: Don't define sigmask.
    * make.h: Put it here instead.

    * variable.c (target_environment): If `.NOEXPORT' was specified as a
    target, only export command-line and environment variables, and
    file-origin variables that were in the original environment.

    * make.man: Add missing ?roff control for `-I' option description.

Thu Sep 13 14:10:02 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

Wed Sep 12 15:10:15 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * expand.c (recursively_expand): Don't use `reading_filename' and
    `reading_lineno_ptr' if they're nil.

Thu Aug 30 17:32:50 1990  Roland McGrath  (roland at geech)

    * Version 3.58.10.

Tue Aug 28 04:06:29 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * job.c [USG] (unknown_children_possible): New variable, set nonzero
    when it's possible for children not in the `children' chain to die.
    (block_signals) [USG]: Set it.
    (unblock_signals) [USG]: Clear it.
    (child_handler) [USG]: Don't complain about unknown children if
    `unknown_children_possible' is set.

    * read.c (do_define): Make sure there's enough space for the newline,
    so we don't write off the end of allocated space.

    * arscan.c (ar_name_equal): Fixed to work when MEM is AR_NAMELEN-1 but
    NAME is not the same length.

Sat Aug 25 16:17:14 1990  Roland McGrath  (roland at geech)

    * job.c (construct_command_argv_internal): Use a static char array for
    a constant, since old C has no auto aggregate initializers.

Thu Aug 23 16:11:03 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * job.c (search_path): If PATH is nil or "" use a default path.

Wed Aug 22 01:05:32 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

    * Version 3.58.9.

    * job.c (exec_command): Don't take PATH and SHELL args.  Get them from
    ENVP.
    (child_execute_job): Don't take FILE arg, and don't pass path and shell
    to exec_command.
    (start_job): Don't pass FILE arg to child_execute_job.
    * function.c (expand_function: `shell'): Ditto.
    * main.c (main): Don't pass path and shell to exec_command.

Fri Aug 17 23:17:27 1990  Roland McGrath  (roland at geech)

    * job.c (construct_command_argv_internal): New fn broken out of
    construct_command_argv.  Takes strings SHELL and IFS instead of doing
    variable expansion for them.  Recurse to make an argv for SHELL,
    passing SHELL==0.  When SHELL==0, don't recurse for shell argv; make a
    simple one using /bin/sh.
    (construct_command_argv): Do the variable expansions and call above.

Thu Aug 16 19:03:14 1990  Roland McGrath  (roland at geech)

    * read.c (multi_glob): For ~USER/FILE, if USER isn't found, don't
    change the file name at all.

Tue Aug  7 18:33:28 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * function.c (expand_function: `suffix'/`notdir'): Don't kill the last
    space if we never wrote one.

    * function.c (expand_function: `suffix'): Retain the dot, like the
    documentation says.

Mon Aug  6 14:35:06 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.58.8.

    * main.c (decode_switches): For positive_int and floating cases, move
    SW past the arg (and don't set it to ""), so another switch can follow.

Fri Aug  3 00:43:15 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * job.c (child_execute_job): Use unblock_signals instead of
    push_signals_blocked_p (0).

    * main.c (fatal_signal_mask): New variable, mask of signals caught with
    fatal_error_signal.
    (main): Set it.
    * job.c ({block,unblock}_children): Renamed to {block,unblock}_signals.
    Block/unblock both child signal and signals in fatal_signal_mask.
    (children_blocked_p_{stack,max,depth}, {push,pop}_children_blocked_p):
    Renamed from children to signals.  Use {block,unblock}_signals instead
    of {block,unblock}_children.
    * commands.c (fatal_error_signal), job.c (wait_for_children, new_job,
    child_execute_job, main, log_working_directory), function.c
    (expand_function: `shell'), job.h: Rename {push,pop}_children_blocked_p
    to {push,pop}_signals_blocked_p.
    * job.c (child_handler): Call {block,unblock}_signals instead of just
    {block,unblock}_remote_children.  We need to block the fatal signals.

Thu Aug  2 22:41:06 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * main.c, function.c: Fixed typos in comments.

    * file.c (print_file_data_base): Fix computation of avg files/bucket.

Tue Jul 31 22:11:14 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.58.7.

Wed Jul 25 16:32:38 1990  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * arscan.c (ar_name_equal): Fixed to really do it right.
    (ar_member_pos): Fixed order of args.
    * ar.c (ar_member_date_1): Ditto.

Fri Jul 20 15:30:26 1990  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * arscan.c (ar_name_equal): Rewritten.  Accounts for a possible
    trailing slash in MEM.

    * remake.c (f_mtime): Keep track of whether ARNAME is used and free it
    if not.  Also free MEMNAME.
    * ar.c (ar_member_date, ar_touch): Ditto.

    * arscan.c (arscan) [HPUX or hpux]: Treat same as USGr3 PORTAR==1.

    * make.h: If NSIG is not defined, but _NSIG is, #define NSIG _NSIG.

    * compatMakefile: Don't use $* in explicit rules.

    * default.c (default_variables: "PREPROCESS.S"): Include $(CPPFLAGS).

    * remake.c (f_mtime): If FILE is an ar ref, get the member modtime.

    * function.c (string_glob): Terminate the string properly when it's
    empty.

Wed Jul 18 11:26:56 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.58.6.

    * commands.c (set_file_variables): Fixed computation for ^F/?F elt len.

Sat Jul 14 13:41:24 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * job.c (construct_command_argv): Always use
    allocated_variable_expand_for_file instead of variable_expand_for_file
    because we might be called from inside a variable expansion (for the
    `shell' function).

    * function.c (expand_function: `shell'): Free the arglist's storage
    correctly.  construct_command_argv only allocates ARGV and ARGV[0].

    * job.c (children_blocked_p_idx): Renamed to children_blocked_p_depth.
    (push_children_blocked_p, pop_children_blocked_p): Use ..._depth
    instead of ..._idx, and do it right!

Wed Jul 11 15:35:43 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * make.h (SIGNAL): New macro to replace `signal' calls.  Does arg and
    ret value casts to (void *) #ifdef __STDC__ to avoid conflicts btwn
    ANSI and BSD `signal' and handler types.
    * main.c (main), job.c (child_handler): Use it.

Fri Jul  6 00:00:38 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * ar.c (ar_member_date, ar_touch): Pass 2nd arg to f_mtime.

    * read.c (read_makefile): Search the include path for MAKEFILES
    variable makefiles (TYPE == 1), like it says in the manual.

    * file.h (struct file), main.c (struct command_switch): Remove trailing
    commas from enums.

    * commands.c (execute_file_commands): Remove unused variables.
    * commands.h: Declare chop_commands.
    * make.h: Declare uniquize_deps.
    * main.c (main): Remove unused variable.
    (decode_switches): Remove unused label.
    * remake.c: Include "ar.h" for ar_parse_name decl.
    * implicit.c (try_implicit_rule): Remove unused variable.
    * function.c (expand_function: `shell'): Declare fork, pipe.
    * ar.c: Declare ar_name_equal.

    * GNUmakefile: If using gcc, add warning flags to CFLAGS.

    * remake.c: Remove decl of ar_member_date, since it's done in make.h.

    * remake.c (f_mtime): For ar refs, allow the archive to be found via
    VPATH search if we're searching, and change the ar ref accordingly.

    * ar.c (ar_parse_name): New global fn to parse archive-member
    references into the archive and member names.
    (ar_member_date, ar_touch): Use it.
    * make.h: Declare it.

    * remake.c (f_mtime): After doing rename_file, do check_renamed instead
    of assuming rename_file will always set FILE->renamed (which it won't).

    * vpath.c (selective_vpath_search): Only accept prospective files that
    don't actually exist yet are mentioned in a makefile if the file we are
    searching for isn't a target.

Wed Jul  4 04:11:55 1990  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

    * remake.c (update_goal_chain): Do check_renamed after calling
    file_mtime.
    (check_dep): Ditto after update_file.

    * file.c (rename_file): Prettied up long message for merging cmds.

    * remake.c (update_file_1): Get each dep file's modtime, and allow for
    it being renamed, before checking for a circular dep, since a renaming
    may have introduced one.

Tue Jul  3 18:15:01 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * ar.c (ar_touch): Don't free ARNAME since enter_file holds onto the
    storage.

    * function.c (string_glob): Don't leave a trailing space.

    * read.c (do_define): Allow leading whitespace before `endef'.

Mon Jul  2 14:10:16 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * implicit.c (pattern_search): No longer take NAME arg.  Instead take
    ARCHIVE flag.  If ARCHIVE is nonzero, FILE->name is of the form
    "LIB(MEMBER)"; rule for "(MEMBER)" is searched for, and LASTSLASH is
    set to nil.  Since NAME was only non-nil when it was the archive member
    name passed by try_implicit_rule, this change easily allows turning off
    LASTSLASH checking for archive members without excessive kludgery.
    (try_implicit_rule): Pass ARCHIVE flag instead of file name.

    * Version 3.58.5.

    free all storage for the chopped args.
    (start_job): Free the argument list's storage correctly.

    * vpath.c (vpath_search): Don't stop the loop if a pattern matches but
    the search fails.  All matching patterns have their paths searched
    (like it says in the manual).

    * make.texinfo (Rules: Directory Search: Selective Search): Say that
    multiple `vpath' directives with the same pattern DO accumulate, not
    supersede earlier ones.

    of push_children_blocked_p (1) and pop_children_blocked_p () instead of
    explicitly blocking and unblocking children.
    * function.c (expand_function: `shell'): Don't unblock children.  The
    push-pop sequence in wait_for_children makes it unnecessary.

Tue May 29 21:30:00 1990  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

    * read.c (do_define): Don't include the last newline in the definition.

    in the parent side of the fork after the child has been spawned.

    * job.c (start_job): If construct_command_argv returns nil, go to the

Thu May 17 15:25:58 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    do this anyway (and lack of declarations is harmless).

    * remote-customs.c: Renamed to remote-cstms.c for System V.
    * remote.c [CUSTOMS]: Changed accordingly.

Sun May 13 14:38:39 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * GNUmakefile: Use same cmds for doc tar.Z as for dist tar.Z (so the

    * Version 3.58.1.

Wed Apr 25 20:27:52 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * default.c (default_variables: PREPROCESS.S): Removed $< from defn.

    * main.c (main): Ignore arguments that are the empty string, rather

    twice on freed rules.

    * GNUmakefile: Made `.dep' files be architecture-specific too.

    * main.c (main, log_working_directory) [USG]: Block children around
    calls to `getwd' (actually `getcwd' on USG), because that function
    sometimes spawns a child running /bin/pwd on USG.

Tue Jan 30 14:02:50 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * function.c (subst_expand): Pay attention to SUFFIX_ONLY, putz.

    it might not have been malloc'd.

    allocated_variable_expand_for_file instead of variable_expand_for_file
    to expand `$(SHELL)'.

    new name, FILE is merged into it and FILE->renamed is set to point to
    it.
    * variable.c (merge_variable_sets): New fn to merge two variable sets.
    (merge_variable_set_lists): New fn to merge two variable set lists.

    `make' itself (instead of the manual) has various chapters.
    (Variables: Advanced: Substitution Refs): When pxref'ing about
    `patsubst', use node `Text Functions', not `Functions'.
    Add an xref about `patsubst' after description of $(var:a%b=c%d).
    (Functions: Syntax of Functions): Explain why mixing delimiters in
    function/var refs is unwise.  Clarify fn arg evaluation order.
    (Options): Reworded sentence about `-e'.
    (Implicit: Implicit Variables): Don't say `RM' is unused.
    Say the dflt values for the flag vars is empty unless otherwise noted,
    since some have defaults.
    (Implicit: Pattern Rules: Pattern Examples): Clarified use of $< and $@
    in first example.
    (Implicit: Last Resort): Don't say the .DEFAULT example creates files
    "silently".  It's automatic, but not silent.

    search path (broken out of exec_command).

    the full pathname of the program (script) to be run.
    (child_execute_job): Pass shell program to exec_command.
    * main.c (main): Ditto.

    try to free it.

    * remake.c (update_file_1): Took code to force remake of nonexistent
    deps out of #if 0, and changed the test to nonexistent non-intermediate
    deps.  In version 4, I think removing this test completely will
    implement the new feature that if a: b and b: c and c is newer than a,
    b need not be remade.

    preceded by an unquoted # in a string.

    cut the line short there before expanding it.  If not, call it again

    updating them, and compare their file_mtimes against this later.  Don't
    re-exec if a makefile was successfully updated but didn't change.  If a
    makefile failed to be remade and no longer exists, die.  If a makefile
    failed to be remade, but changed anyway, re-exec.  If a makefile failed

    checking for it being "".

    * main.c (define_makeflags): Fixed test for whether a flag/flag_off

    Make will grok (except for FP/int values and new flags).

    * job.c (child_execute_job): Don't use the shell's -c option.
    Also fixed an off-by-one bug in the ARGV -> shell arg list copying.

    * load.c [LDAV_BASED] (load_average): Check for == -1, rather than < 0
    to see if lseek fails.  On some systems, `avenrun' is at an offset >

Mon Sep  4 11:07:58 1989  Roland McGrath  (mcgrath at saffron.Berkeley.EDU)

    * rule.c (new_pattern_rule): Return `int' instead of `void': nonzero if
    the passed rule was used, zero if not.
    (install_pattern_rule): Pay attention to the return from

    commands unless it's used.
    (create_pattern_rule): Same idea.

    * dir.c (find_directory): Removed unused variable.

    * commands.c (execute_file_commands): Removed unused variable.

    * Version 3.55.1 (alpha).

    * function.c (string_glob): Don't add spaces after file names that
    aren't added.  (Also means don't add spaces without checking the size
    of the buffer.)

    * remake.c (update_goal_chain): Don't remove makefiles with cmds and no
    deps from the chain.
    * main.c (main): Do it here, before calling update_goal_chain.

    * remake.c (update_goal_chain): When updating fails, change STATUS even
    if MAKEFILES is set.  Also stop remaking when updating fails if not
    under -k and MAKEFILES is not set.

    * remake.c (remake_file, update_file_1, notice_finished_file),
    commands.c (execute_file_commands), make.h, commands.h: The functions
    remake_file, notice_finished_file, and execute_file_commands no longer
    return values, and their callers no longer expect values returned.

    replace it with the name stored in read_makefiles by read_makefile.

    * remake.c (update_file_1): Don't decide not to remake if FILE has no
    cmds and no deps actually changed if FILE doesn't have any deps.

    * file.c (remove_intermediate): Remove precious files that also have
    the `dontcare' flag set.

    * remake.c (update_file_1): Don't always remake if FILE has cmds but no
    deps; only if FILE is double-colon.  (I don't know why this should be
    done for double-colon targets, but that's what Unix make does.)

    * load.c [LDAV_BASED] (load_average): Write error messages if the
    various system calls fail.  Keep track of if we've failed before.
    The first time we fail, write a message saying -l won't be enforced.
    The first time we succeed after having failed, write a message saying
    -l will be enforced again.

    * remake.c [USG]: Don't #include <sys/file.h>

    * load.c [generic Unix LDAV_BASED]: #include <fcntl.h> #ifdef USG,
    else <sys/file.h> instead.

    * job.c [USG && !USGr3 && !HAVE_DUP2]: Remove redundant
    #include <errno.h> and declaration of `errno'.
    [...] (dup2): Fixed so it won't always lose.

    * default.c (default_suffix_rules: .texinfo.dvi): Copy, rather than
    move, the aux and index files, so the TeX run can use them.

    * compatMakefile: Remove redundant comment.

    * load.c [generic Unix LDAV_BASED]: Include <a.out.h> instead of
    <nlist.h>, since the `struct nlist' declaration in <nlist.h> varies
    more than the one in <a.out.h>.
    (load_average): Use the `n_un.n_name' field of the `struct nlist',
    since the <a.out.h> declaration uses the union.

    * main.c (main): For the temporary files made for stdin makefiles, set
    the `intermediate' and `dontcare' flags.
    * file.c (remove_intermediates): Don't print any messages for files
    whose `dontcare' flag is set.  (The only files that will be
    intermediate and `dontcare' will be the temporary files made for stdin
    makefiles.)

    * job.c (exec_command): Made global.
    * job.h: Declare it.
    * main.c (main): Use exec_command when re-execing.

    * make.h: Declare environ.
    * make.c: Don't.

    * job.c (child_execute_job): New function to perform everything done in
    the child side of a fork (for a job or `shell' function).
    (start_job): Call it.
    * job.h: Declare construct_command_argv and child_execute_job.
    * function.c (expand_function: `shell'): Use child_execute_job.

    * function.c (expand_function: `shell'): Remove a trailing newline
    instead of turning it into a space.

    * main.c (main): Do init_siglist #ifdef HAVE_SIGLIST.

    * job.c [WTERMSIG || (USG && !HAVE_SYS_WAIT)]: Test each W* macro
    separately and define all those that aren't defined.

Sat Aug 26 15:13:21 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * ar.c (ar_name): Return zero for `(foo)'.

    * Version 3.55.

    * make.texinfo (Rules: Multiple Targets): Make this node's `next'
    pointer point to `Static Pattern'.
    * make.texinfo (Makefiles: MAKEFILES Variable): Make this node's `prev'
    pointer point to `Makefile Names'.

    * make.1: Renamed to make.man.
    * compatMakefile: Define `mandir' and `manext'.
    (install): Depend on $(mandir)/make.$(manext).
    ($(mandir)/make.$(manext)): Depend on make.man and copy it to $@.
    ($(bindir)/make): Use `make' rather than $<; so Unix make can grok it.

Thu Aug 24 03:35:48 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * variable.c (target_environment): Allow variables that start with

    * GNUmakefile (make-$(version).tar.Z): Put make.1 (the Unix manual
    page) in the tar file.

    * variable.c (target_environment): Don't write variables with origin
    o_default (i.e., ones from default.c).
    * make.texinfo (Commands: Recursion: Variables/Recursion): Document
    that default variables are not put in the environment.

    * remake.c (update_file_1): Remake all targets with commands but no
    deps.

Sat Aug 19 06:03:16 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * remake.c (update_file_1): In the final loop, set the deps'
    `changed' members if they are newer than FILE.

    * remake.c (update_goal_chain): Under -d, print a message if we decide
    not to remake a makefile so as to avoid a possible infinite loop.

Fri Aug 18 20:30:14 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * remake.c (remake_file): Cleaned up.

    * commands.c (execute_file_commands): If the commands are empty, set
    FILE->update_status to zero before returning.

    * remake.c (notice_finished_file): Set `last_mtime' fields to zero
    instead of calling name_mtime; file_mtime will do that later if anybody
    cares.

Thu Aug 17 10:01:11 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * make.texinfo (Rules: Wildcards: Wildcard Examples): Give this node a
    `prev' pointer.

    * Version 3.54.9 (alpha).

    * make.texinfo: Fixed some @nodes.

    * remake.c (check_dep): Don't set *MUST_MAKE_PTR if FILE doesn't exist
    after running update_file.

    * remake.c (notice_finished_file): If FILE has no commands, pretend its
    modtime is now.

    * remake.c (update_file_1): In the loops that call update_file on the
    deps, compare modtimes before and after (unless deps are still being
    made) and set the deps' `changed' members.  Do not set the `changed'
    members in the loop that prints the newer/older debugging messages.
    * remake.c (update_file_1): If no deps changed and FILE has no
    commands, decide it doesn't need remaking.

    * remake.c (update_file_1): Print a debugging message if we take
    commands from default_file.

    * make.texinfo (Rules: Directory Search: Selective Search): Removed
    note about warning for `vpath' with a constant pathname, since it isn't
    warned about anymore.

    * remake.c (update_goal_chain): If MAKEFILES, remove makefiles which
    are targets and have no deps.
    * make.texinfo (Makefiles: Remaking Makefiles): Document that makefiles

    error), return instead of exiting the child process.

    * job.c (start_job): In the child side, if exec_command fails, try
    using the shell.

    * job.c (start_job): In the child side, call unblock_children instead
    of sigsetmask.

    * remake.c (notice_finished_file): Under -n or -q, always increment
    files_remade for non-phony files.

    * rule.c (intall_pattern_rule): Use find_percent.

    * vpath.c (vpath_search): Pass the `percent' members to
    pattern_matches.

    the pattern where the % is.
    (construct_vpath_list): Call find_percent on the pattern and set the
    new `percent' member.
    * read.c (read_makefile): Don't run find_percent on `vpath' directive
    patterns.

    PATTERN where the % is.  If PERCENT is nil, copy PATTERN into local
    space and run find_percent on it.
    (expand_function: `filter', `filter-out'): Pass new arg to
    pattern_matches.
    * read.c (record_files): Pass PATTERN_PERCENT to pattern_matches for

    (create_pattern_rule): Take new arg TARGET_PERCENTS, nil or an array of
    pointers into the corresponding elements of TARGETS, where the %s are.

    and README-doc to go into the two distribution tar files.
    * GNUmakefile: Added a rule to edit the version number in
    README.template and README-doc.template, producing README and
    README-doc.

    * remake.c (update_goal_chain): If -n or -q is in effect for a
    makefile, and it got updated, don't change STATUS, so we can still
    return -1 (meaning nothing was done).  This avoids an infinite loop on
    "make -n Makefile".

Sat Aug 12 23:14:24 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * remake.c (notice_finished_file): Treat -q the same as -n.

    * remake.c (update_goal_chain): Fixed handling of return from
    update_file.  If -n or -q is in effect, ignore it.

    * job.c (start_job): Don't test for -t.  We should never get called in
    that case.

Fri Aug 11 04:09:14 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * remake.c (update_file): Don't print "up to date" messages for
    phony files.

    start_job returns nonzero under -n or -t.

    * expand.c (variable_expand): Count parens in $(foo:a=b) refs.

    * main.c: Removed old declaration of `glob_tilde' (which hasn't existed
    for a few months).

Tue Aug  8 23:53:43 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * job.c (exec_command): Fixed to not ignore the last path component and
    to do the right thing with an empty path.

Fri Aug  4 15:58:19 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * remake.c (library_file_mtime): Look for libLIB.a, not /libLIB.a.

    * remake.c (remake_file): If FILE has no commands and is a target,
    don't set its time to now.  The time gets reset by notice_finished_file
    anyway, and it isn't needed since check_dep checks for nonexistence.

    * Version 3.54.6.

    * read.c (read_makefile): Don't read off the end of the string after an
    `include'.

    * job.c (exec_command): New function to search the path for a file and
    execute it.
    (start_job): Use exec_command rather than execvp.

    * read.c (read_makefile): Expand `include' directive args before
    parsing them.  Allow trailing whitespace after filename.

    * variable.c (target_environment): Put makelevel + 1, rather than
    makelevel, in the `MAKELEVEL' envariable.

Sat Jul 29 10:27:04 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * remake.c (notice_finished_file): Don't get the new modtime of phony
    files.

    nonzero if any `lines_recurse' element is nonzero.
    * commands.c (chop_commands): Set the `any_recurse' member.

    * commands.c (execute_file_commands): Split chopping of commands into
    lines into new function chop_commands.
    * commands.h: Declare chop_commands.

    * read.c (read_makefile): Test for a line beginning with a tab after

    USG, since HP-UX defines a `struct file' there.

Fri Jul  7 12:11:30 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * job.c: If WTERMSIG is defined by <sys/wait.h>, define WAIT_T as int,
    and don't define other macros; this covers HP-UX.
    If WTERMSIG is not defined, use int or union wait based on USG and
    HAVE_SYS_WAIT; this covers BSD and SysV.

    buffer, use variable_buffer_output instead of a simply zero store,
    because the buffer may need to be enlarged.

Wed Jun 28 16:53:47 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * Version 3.54.

    * default.c (default_suffixes): Added `.ln'.

    * job.c (start_job): If there are no more commands, return nonzero
    under -n or -t.

    * compatMakefile (make): Pass `-f' to mv.

    * GNUmakefile (depend): Split commands into two lines so they won't be
    so long when variable-expanded.

    * compatMakefile: Documented MINUS_C_MINUS_O meaning.  The line
    describing it got removed when the USG/wait stuff was documented.

Sat Jun 17 22:56:54 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)

    * Version 3.52.

Mon Jun 12 17:45:11 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.51.

    * make.texinfo (Features): Noted 1003.2 requirement of `+' meaning.

    * file.c (remove_intermediates): If !SIG, write a single "rm" command
    line, listing all files.

    * read.c (read_makefile): Don't free the storage for the passed
    filename, since it might not be malloc'd.  When doing an included
    makefile, free the name's storage.

    * commands.c (start_job): Don't collapse backslash-newlines here.
    (execute_file_commands): Collapse backslash-newlines before chopping
    the commands up into lines.

    * commands.c (set_file_variables): Initialize the length counters for
    $^ and $? to zero!

    * commands.c (start_job): Use vfork instead of fork.  Someone else says
    the child and parent DO have separate file descriptors.

    * variable.c: Split internals into variable.c, function expansion into
    function.c, and variable expansion into expand.c.
    * function.c (handle_function): New function to check for a function
    invocation and expand it.

    * remake.c (library_file_mtime): Check for libNAME.a in the current
    directory before doing VPATH search.

    * variable.c (print_variable_set): Don't write "# Variables", and write
    fewer blank lines.
    (print_variable_data_base): Precede the variables with "# Variables".

    * make.c (main): Print the data base under -p after doing everything
    else, just before exitting.  This way it gets info determined in
    updating the goal targets.

    * variable.c (print_variable_data_base): Split into print_variable,
    which prints one variable, and print_variable_set, which prints a set.
    Replaced with a call to print_variable_set for the global set.
    (print_file_variables): New function to print a given file's local
    variables.

    * file.c (print_file_data_base): Call print_file_variables to print
    each file's local variables.

    the $^ and $? variables!!!

    * make.texinfo (Implicit: Pattern Rules: Automatic): Document new D and
    F versions of $^ and $?.

    * commands.c (start_job): In the child fork, use getdtablesize and a
    loop to close all file descriptors other than 0, 1, and 2.  We need to
    do this since not only the bad stdin pipe, but also some directories,
    may be open.

    * commands.c (start_job): Use fork instead of vfork, because a vfork
    parent and child share file descriptors, and our child needs to diddle
    with stdin.

    * variable.c (initialize_file_variables): When created a new variable
    set, zero out the hash table.

    * variable.c (target_environment): Don't use variables whose names are
    not made up of alphanumerics and underscores.

    * remake.c (update_file_1): Set the `parent' member of each dependency
    to FILE before updating it.

    * file.h (struct file): Add `parent' member.

    * variable.c (initialize_file_variables): Don't take second arg PARENT.
    Use FILE->parent instead.  If FILE->parent->variables is nil, recurse
    to initialize it.

    * variable.h: Declare {allocated_}variable_expand_for_file.

    * variable.c (allocated_variable_expand): Now
    allocated_variable_expand_for_file, calling variable_expand_for_file,
    and taking second arg FILE.
    (allocated_variable_expand): New function, a wrapper around
    allocated_variable_expand_for_file, passing a nil second arg.

Fri Jun  9 12:11:45 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * commands.c (start_job): On the child side of the fork, always close
    the bad stdin file descriptor.

    * commands.c (struct child): New member `environment', to hold the
    environment for the child.
    (execute_file_commands): Set the new childs `environment' member to nil
    before calling start_job.
    (start_job): Set up CHILD->environment before running the commands if
    it is nil.

    * make.c (main): Don't call new_environ.  `shell' functions will now be
    run with the environment make was called with.

    * commands.c (child_handler): Don't check C->command_ptr before calling
    start_job since we now have to check C->file->cmds->command_lines and
    it's easier to let start_job handle all that.

    * commands.c (struct child): New member `command_line', to hold an
    index into file->cmds->command_lines.
    (execute_file_commands): Set the new child's `command_line' to 0 and
    its `commands' and `commands_ptr' to nil.
    (start_job): When CHILD->command_ptr runs out, increment
    CHILD->command_line and run the corresponding line from
    CHILD->file->cmds->command_lines.  Run it even under -t, -q, or -n if
    the CHILD->file->cmds->lines_recurse element for that line is set.

    * commands.c (execute_file_commands): Chop CMDS up into lines, setting
    its `command_lines' and `lines_recurse' members, if it wasn't already
    chopped.

    * commands.h (struct commands): New members `command_lines' and
    `lines_recurse'.  The first is an array of chopped-up lines; the second
    is an array of flags, each nonzero if the corresponding line is
    recursive.

    * variable.c (variable_expand_for_file): If FILE is nil, just do a
    vanilla variable_expand.
    (expand_function: `shell'): Pass second arg (as nil) to
    construct_command_argv.

    * commands.c (construct_command_argv): Use variable_expand_for_file on
    `$(SHELL)' and `$(IFS)' instead of lookup_variable to check those
    variables.  This handles file-local and recursive values correctly.
    To support this, take an additional argument FILE.

    * variable.c (initialize_file_variables): New function to initialize
    FILE's variable set list from PARENT's setlist.  PARENT is the
    immediate dependent that caused FILE to be remade, or nil if FILE is a
    goal.  (When user-level per-file variables are implemented, PARENT
    should be passed as nil when defining per-file variables.)

    * variable.c (variable_expand_for_file): New function to expand a line
    using the variable set of a given file, and reporting error messages
    for the file and line number of that file's commands.

    * variable.h: Don't declare lookup_variable_for_file.

    * variable.c (lookup_variable_*): Turned back into lookup_variable.  It
    now uses current_setlist.
    (global_setlist): New static `struct variable_set_list', a setlist
    containing global_variable_set.
    (current_setlist): New static `struct variable_set_list *', a pointer
    to the current variable set list.
    (define_variable): Define in the current top-level set, not the global
    set.

    * commands.c (set_file_variables): New function to set up the automatic
    variables for a file in its own variable set.
    (execute_file_commands): Use set_file_variables.

    * variable.c (new_environ): Replaced with target_environment, taking an
    argument FILE, and returning an environment for FILE's commands.

    * variable.c, variable.h: Remove all global special variable pointers.

    * variable.c (define_variable_for_file): New function like
    define_variable, but takes additional arg FILE, and defines the
    variable in the variable set at the top of FILE's chain.
    (lookup_variable_for_file): New function like lookup_variable, but
    takes additional arg FILE, and looks the variable up in all of FILE's
    variable sets.

    * file.h (struct file): New member `variables', a `struct
    variable_set_list' containing the list of variable sets used in the
    expansion of the file's commands.

    * variable.c (variables): Replaced with static `struct variable_set'
    global_variable_set.
    (define_variable): Now define_variable_in_set, taking additional
    argument SET, the `struct variable_set' to define it in.
    (define_variable): Use define_variable_in_set with global_variable_set.
    (lookup_variable): Now lookup_variable_in_set, taking additional
    argument SET, the `struct variable_set' to look it up in.
    (lookup_variable): Use lookup_variable_in_set with global_variable_set.
    (lookup_variable_in_setlist): New function to look up a variable in a
    `struct variable_set_list' using lookup_variable_in_set.

    * variable.h (struct variable_set): New structure, containing a hash
    table and the number of hash buckets.
    (struct variable_set_list): New structure, containing a link for a
    linked-list, and a `struct variable_set'.

    * commands.c (start_job): Under -n, return what the recursive start_job
    call returns, since it might actually start a child.

    * make.texinfo (Rules: Wildcards): Document ~ and ~USER expansion.

    * commands.c (execute_file_commands): If start_job returns
    failure, but -t is set, set FILE->update_status to success.
    (start_job): If -t is set, and the commands are not recursive, return
    failure (is is done for -q).

    * remake.c (touch_file): New function to touch FILE.
    (remake_file): Use touch_file.  When touching a file, still do
    execute_file_commands.

    * remake.c (remake_file): Don't check question_flag (-q), since we
    can't know here if the commands are recursive.

    * commands.c (start_job): Don't use the `recursive' member of
    CHILD->file->cmds.  Instead, check for leading +s and $(MAKE) or
    ${MAKE} in the command line here.

    * commands.h (struct commands): Remove `recursive' member.

    * rule.c (install_default_pattern_rules): Remove use of `recursive'
    member.

    * read.c (record_files): Don't check commands from $(MAKE) and set
    their `recursive' member.

    * commands.c (fatal_error_signal): Treat SIGQUIT like SIGINT, SIGHUP,
    and SIGTERM, but don't send it to ourselves because it will cause a
    core dump.

Thu Jun  8 20:30:04 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.50.

    * variable.c (variable_expand): Use allocated_variable_expand instead
    of expand_argument in a few places.

    * variable.c (allocated_variable_expand): Do static variable shuffling
    here instead of using expand_argument.
    (expand_argument): Use allocated_variable_expand.

    * variable.c (recursively_expand): New function to recursively expand
    its argument (a `struct variable'), returning the malloc'd value.
    (variable_expand): Use recursively_expand.

Sun May 28 12:49:27 1989  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (main): Fixed buggy fix in deciding to increase space for
    command-line variable definitions.  (First it never did it, then it
    always did it; now it does it when necessary.)

Sat May 27 14:01:54 1989  Roland McGrath  (mcgrath at hecuba.Berkeley.EDU)

    * make.c (main): Fixed bug in deciding to increase space for
    command-line variable definitions.

Fri May 26 15:48:01 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * read.c (multi_glob): Use allocated_expand_variable for checking
    `HOME' variable for ~ expansion, since this may be called from inside a
    `wildcard' function expansion.

    * variable.h: Declare allocated_expand_variable.

    * variable.c (allocated_expand_variable): New function to do variable
    expansion in an allocated buffer, rather than the static one.

    * make.c (main): Don't set glob_tilde (it no longer exists).

    * variable.c (string_glob): Use multi_glob and parse_file_seq.

    * read.c (multi_glob): Do ~ expansion here.

    * glob.c (glob_tilde, glob_filename): Removed ~ expansion.

    * variable.c (define_variable, lookup_variable): Use a smarter hashing
    algorithm (the same one used for files and directories).
    (VARIABLE_BUCKETS): Increased to 523.

    * file.c (enter_file, lookup_file, rename_file): Use a smarter hashing
    algorithm, spreading the bits about somewhat.

    * make.c (log_working_directory): Under `-p', precede the directory
    message with a `#'.

    * make.c (print_version): Under `-p', precede each line with a `#'.
    (print_data_base): Precede the header line with a `#' and include the
    date and time on it.

    * vpath.c (print_vpath_data_base): Precede non-directive
    lines with `#'s.

    * commands.c (print_commands): Precede the non-command line with a `#'.

    * rule.c (print_rule_data_base), file.c (print_file_data_base): Precede
    non-rule lines with `#'s.

    * dir.c (print_dir_data_base): Precede all lines with `#'s.

    * variable.c (print_variable_data_base): Changed format so that it can
    be makefile input.  Lines that are not variable definitions are
    preceded with `#'.  Nonrecursive variable definitions are made with all
    dollar signs doubled to reproduce the initial value.  Recursive
    variable definitions containing newlines are done with `define'
    directives.  Nonrecursive variable definitions containing newlines, and
    variable names containing :, =, or newlines, will come out garbled.

Wed May 24 00:20:04 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.49.

    find_percent instead of pattern_p.

    * variable.c (expand_function: `patsubst'): Pass new args (both nil)
    to patsubst_expand.
    (variable_expand): For $(var:pat%=rep%) references, pass new args to
    patsubst_expand so as to avoid find_percent and thus disallow
    quoting the %s.

    * read.c (record_files): Pass new args to patsubst_expand.

    * variable.c (patsubst_expand): Take two new args: PATTERN_PERCENT
    and REPLACE_PERCENT.  Each of these, if non-nil, means that PATTERN
    (or REPLACE) has already been run through find_percent, and
    PATTERN_PERCENT (or REPLACE_PERCENT) is the result.

    * make.h: Declare find_percent instead of pattern_p.

    * read.c (pattern_p): Changed to find_percent, returning a pointer
    to the %, or nil if there is none.

    * read.c (pattern_p): Made global.
    * make.h: Declare pattern_p.

    * read.c (pattern_p): New function to search for an unquoted % in a

    nonzero if an unquoted % was found, zero if not.
    (record_files): Use pattern_p to check for implicit rules.
    (read_makefile): Use pattern_p to check for static pattern rules.
    Also use it to allow quoted %s in `vpath' patterns; warn about

    next command line.

    * commands.c [USG] (init_siglist): Don't case SIGEMT if it's not

    incrementing the count of files remade.

    * commands.c [USG] (init_siglist): If both SIGCHLD and SIGCLD are

    If not just remove the old one for put in the new one.

    * remake.c (update_file_1, check_dep): Changed it back so that equal
    modtimes to NOT make dependencies be considered newer.  RCS checks
    out files with equal modtimes as the RCS files, so this screws it.

    * make.h, glob.c: If __GNUC__ is defined, use __builtin_alloca.

    * Makefile: Use variables `ALLOCA' and `ALLOCASRC' so systems
    without a good standard alloca can get it from the Emacs

Mon Mar 20 10:21:22 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.42.

    * rule.c (default_variables): Set F77 to $(FC) and F77FLAGS to
    $(FFLAGS) so explicit rules expecting these (which are in System V)
    will work.  However, there is no way to make setting these affect
    the implicit rules, unless we trash FC and FFLAGS (which BSD uses).
    [USG]: Set GET to `get' rather than `/usr/sccs/get'.

    * file.c (rename_file): If a file with the new name already existed,
    use the same storage space, after freeing the old file's name, deps,
    and `also_make' member, preserving the link in the chain.

    I don't think this should be able to happen, but I'm not sure.

    * file.c (rename_file): Don't add the hash values of the old and new
    names together!  Reset HASHVAL before computing the second value.

    * dir.c (check_changed_directories): Zero the new file hash table
    after allocating it.

    * dir.c (dir_file_exists_p): If FILENAME is "", return 1 if the
    directory exists.

    * vpath.c (check_changed_vpaths): New function to run through the
    search paths of all VPATHs, making the `exists' members correspond
    to reality.

    returning.
    make.h: Declare check_changed_directories.

    * Version 3.40.

    * make.c (print_version): Made the copyright say 1988, 1989.

    * read.c (read_all_makefiles): Don't set *MAKEFILES to the name of
    the end of the read_makefiles chain, since the latter may be from an
    included makefile.  (Why did I do this before?)

    * make.c (main): Set argv[0] to "" if it was nil.  Don't put the
    command-line variable definitions into argv[0], only into the MAKE

    * commands.c (block_children, unblock_children): Make these globally
    visible (not `static').
    commands.h: Declare block_children and unblock_children.

    unblock after `shell_function_pid' is set properly and
    `shell_functon_completed' is reset to 0.

    * commands.c (child_handler): When the child of the `shell' function
    completes, set `shell_function_completed' to 1 if it actually ran,

    block and unblock the child termination signal.

    * variable.c (expand_function: `shell'): Close the read side of the
    pipe on the parent side of the fork.

    * commands.c (start_job): On the child of the fork, close the
    BAD_STDIN fd if we're not using it.

    * read.c (record_files): A file beginning with a dot can be a
    default target if it also contains a slash (as in `../foo').

    * commands.c (wait_for_children): For BSD, block SIGCHLD rather than
    ignoring it to avoid a race condition when child_handler is returning.

    * commands.c (child_handler): Do blocking waits.
    (error_status): Return a string describing exit status.  (Split out
    of child_handler).

    * read.c (multi_glob): Change VECTOR to VEC for Alliant.

    * rule.c: Revamped default suffix rules.  They now use Sun's style
    of using variables `COMPILE.c', `LINK.c', etc. for each suffix, and
    use `TARGET_ARCH' and `TARGET_MACH' variable where appropriate.
    Also support Modula-2 compilation (suffixes .sym, .def, and .mod).
    Ratfor Yacc support is gone, since nobody has yacc -r.
    All EFL support is gone, since nobody uses EFL.

    * ar.c, arscan.c: Don't assume `long int' and `int' are the same.

    * commands.c [USG]: Fixed wait status bit encoding.
    [USG and not USGr3] (dup2): Define this for SysVr2.

    and wait3 even if USG.

    * read.c (record_files): Defining .DEFAULT with no deps or commands
    clears its commands.

    * rule.c (default_suffixes): Added `.sh'.

    default list ("" under -r).
    make.texinfo (Suffix Rules): Document `SUFFIXES' variable.

    * rule.c (default_variables), make.texinfo (Implicit Variables):
    Variable AR defaults to `ar', ARFLAGS to `rv', and RM to `rm -f'.

    * rule.c (install_default_pattern_rules): Default variables are made
    recursive.
    (default_variables): Added "CPP", defined to "$(CC) -E".
    (default_suffixes): Added `.S', before `.s'.
    (default_suffix_rules): New rule for .S to .s, runs CPP.
    All rules that use CPP now include "$(CPPFLAGS)".
    make.texinfo (Catalogue of Implicit Rules, Implicit Variables):
    Documented above changes.

    equivalent to `$(patsubst PAT,SUB,$(foo))'.

    * variable.c (variable_expand): Free the storage for the expansion
    of a recursive variable when it is nod longer needed.

    * variable.c (variable_expand): When checking for `$($(foo))', use
    lindex so as not to search for the second `$' outside the parens.

    * make.c (struct stringlist, main, decode_switches): Changed `index'
    member to `idx'.

Sat Dec 24 16:02:32 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * commands.c (wait_for_children [USG]): Handle SIGCLD with SIG_DFL,
    rather than SIG_IGN.  Ignoring SIGCLD reportedly makes wait return -1.

    * arscan.c [USGr3]: Define PORTAR to 1 (as with sun386).
    (ar_scan [USGr3]): Remove trailing slashes from member names.

Thu Dec 22 17:54:05 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * make.texinfo (Makefiles: Overriding Makefiles): New node
    documenting use of .DEFAULT to have one makefile defer unmakeable
    targets to another.

    * make.texinfo (Implicit: Using Implicit, Implicit: Last Resort):
    Mention empty commands and xref node `Empty Commands'.

    * Version 3.29.

    * make.c (struct command_switch, command_switches, et al): New
    member `noarg_value', if not nil, ptr to value to use if no arg is
    given to a switch that would otherwise require one.  The -j option
    can now be given w/o an arg, to mean infinite jobs.
    * commands.c: If job_slots is zero, infinite jobs.

    * read.c (read_all_makefiles, read_makefile): Make makefiles precious.

    * make.c (decode_switches): For a positive_int or floating option,
    if we moved to the next argument word, but found no argument for the
    option, move back to the correct word.

    * make.c (decode_switches): If we got any unknown options, die after
    processing all arguments.

    * GNUmakefile: Moved `include depend' to the end, so the default
    goal will be set before then.

    * load.c (wait_to_start_job [Unix, UMAX]): Merged into one version
    under #ifdef LDAV_BASED.  Only loop while we have jobs running.
    Sleep for increasing amounts (increase one second per iteration)

    * commands.c (start_job): Call wait_to_start_job before forking.

    * load.c (load_average): Converted to wait_to_start_job.

    * remote.c: New file for remote execution functions.
    (start_remote_job_p): Return nonzero if the next job should be run
    remotely.
    (start_remote_job): Start a remote job and return an ID for it.
    (remote_status): Get status of dead remote children.

Fri Dec 16 16:51:07 1988  Roland McGrath  (mcgrath at hecuba.Berkeley.EDU)

    * commands.c (start_job): If start_remote_job_p () returns nonzero,
    call start_remote_job to start the job rather than fork and exec.
    (child_handler):

    * commands.c (execute_file_commands): Moved load average checking to
    start_job.

    * commands.c (child_handler: USG): Record the pid wait returns.

    * load.c (UMAX): Added some #include's needed for UMAX.

    * read.c (multi_glob), variable.c (string_glob): Ignore a (char **)
    -1 return from glob_filename.

    name, set its contents equal to FILE's (ick).

    * variable.c (define_automatic_variables): Pass all the args to
    define_variable when defining MAKELEVEL!

    * commands.c (execute_file_commands): If max_load_average > 0, and
    we have children running, don't start up another child until the
    load average goes below max_load_average.

    * make.c: New variable `max_load_average'.
    (struct command_switch, decode_switches, decode_env_switches):
    Handle floating-point (double) args.
    (command_switches): Added `-l' switch to set `max_load_average'.

Thu Dec 15 15:22:08 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * Makefile: Renamed to oldMakefile.
    * GNUmakefile: Make Makefile from oldMakefile and depend.

    * read.c (read_all_makefiles): When putting the default makefiles in
    the read_makefiles chain so they will be remade, put them in the
    right order.

    * remake.c (update_goal_chain): If MAKEFILES is nonzero, always make
    in serial, and return as soon as one goal whose `changed' member is
    nonzero  is successfully remade.

    * commands.c: Don't include <sys/fcntl.h>.

    * commands.c (construct_command_argv): Added ` to sh_chars.

    * make.h: Don't declare construct_makeflags.

    * make.c (main): Set up MAKEFLAGS and MFLAGS and make an environment
    both before and after reading the makefiles, so the makefiles can
    use them and possible change them, and later children will get the
    right information.
    (construct_makeflags): Replaced with define_makeflags (static void),
    which defines the two variables.
    * variable.c (define_automatic_variables): Don't define MAKEFLAGS
    and MFLAGS.

Mon Dec 12 14:40:31 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

    * Version 3.27.

    * commands.c (child_handler): Reset the handler to ourselves when
    called for USG, since it has no safe signals.

    * commands.c: For USG, use an int rather than a `union wait' for
    wait calls, and dissect it with bitmasks.
    (child_handler): No wait3 system call in USG.  Since we can't
    protect from hanging, always return immediately if we have no
    children we know about and we're not running a `shell' function.
    (There is still the danger of hanging waiting for a child that died
    without our being notified.)

    * remake.c: Include <fcntl.h> instead of <sys/file.h>.  What we need
    is really in <fcntl.h>, and while BSD <sys/file.h> includes
    <fcntl.h>, USG doesn't.

    * make.c (main): Figure out the program name before doing anything
    which might need it (in a call to error or fatal).

    * dir.c, glob.c: Use `struct dirent' and <dirent.h> for USGr3.

    * arscan.c (ar_scan): Added missing & before buf (which is an int)
    if SARMAG is not defined (SysV).

Fri Dec  9 18:44:13 1988  Roland McGrath  (mcgrath at pepper.Berkeley.EDU)

    * Version 3.26.

    * dir.c (find_directory, dir_file_exists_p): Keep track of how many
    directories we have open and don't let it be more than
    MAX_OPEN_DIRECTORIES (currently 10).

    * variable.c (expand_function: `foreach'): Use expand_argument
    rather than variable_expand so each repetition doesn't clobber the
    last!!!

Mon Dec  5 15:58:46 1988  Roland McGrath  (mcgrath at hecuba.Berkeley.EDU)

    * Version 3.25.

    * Makefile: Define `install' target.

    * GNUmakefile: Don't include GNUmakefile or depend in the
    distribution file.

Wed Nov 30 15:53:42 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

    * commands.c (execute_file_commands): Don't clobber a null into
    random storage if there were no $^ and/or $? words.

    * remake.c (check_dep): Set *MUST_MAKE_PTR nonzero if a dependency
    doesn't exist.

    * ar.c (ar_member_date, ar_touch): Make sure the modtime of the
    archive file itself is known before we fetch or change the modtime
    of one of its members.

    * read.c (read_makefile): Expand variable and function references
    before parsing rules so variable can contain special characters
    (colons and semicolons).

Sat Nov 26 11:36:31 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * variable.c (expand_function: `filter', `filter-out'): Fixed so
    that filter-out works right.

    * variable.c (expand_function: `filter', `filter-out'): Made these
    functions use each word of their first argument as a pattern.

Fri Nov 25 10:51:47 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.24.

    * read.c (record_files): If a target is listed more than once in a
    single rule (that defines commands), give a warning message rather
    than the counter-intuitive message saying commands were already
    defined (in the same place).

    * make.c (fatal, error): Made them both take 6 args since there is
    at least one error message that need that many.  Too bad vfprintf is
    not universal!

    * Version 3.23.

    * read.c (read_makefile): Moved the construction of the `struct
    commands' into record_files.  Call record_files before recursing for an
    included makefile so the higher-up will determine the default goal.
    (record_files): Take arguments COMMANDS, COMMANDS_IDX and
    COMMANDS_STARTED and construct a `struct commands.

Thu Nov 24 14:36:33 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * Version 3.22.

    * make.c (main): Made it a fatal error if we can't move back to the
    directory we started in before re-execing.

    * make.c (main): Get the current directory before doing anything
    else, so we know it even if we don't need it for the value of
    `MAKE', since we might want it when re-execing.

Wed Nov 23 13:34:44 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * Version 3.21.

    * read.c (record_files): Eliminate duplicate deps in a chain.

    * variable.c (expand_function: `sort'): Pass the right number to
    qsort, not one less.

    * remake.c (remake_file): Always call notice_finished_file if
    FILE->command_state == cs_finished.

    * commands.c (execute_file_commands): Call notice_finished_file to
    set FILE's status correctly when start_job fails (because it's out
    of commands or running under -n).

Fri Nov 18 15:31:12 1988  Roland McGrath  (mcgrath at saffron.Berkeley.EDU)

    * Version 3.20.

    * remake.c (update_file_1): Set the `update_status' of FILE to
    nonzero and set FILE's `updated' bit if we have decided to give up
    on remaking FILE because of errors in the dependencies.

    * rule.c (pattern_search): Debugging messages use `dependency' (vs.
    `dependent') properly.

    * make.texinfo (Conditionals: Conditional Syntax): Function index
    entries for `ifndef' and `ifneq'.

    * variable.c (define_automatic_variables): Define `MAKELEVEL' to the
    decimal number of the makelevel, since it may be malformed or blank.

    * remake.c (remake_file): Call notice_finished_file after touching.

Fri Nov 11 08:02:26 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (fatal, error): Made error messages for recursive runs be
    shorter.

Thu Nov 10 16:51:36 1988  Roland McGrath  (mcgrath at basil.Berkeley.EDU)

    * Version 3.18.

    * read.c (read_makefile): Made it eat leading spaces and formfeeds
    (but not tabs), like it's documented to.

    * read.c (read_makefile): Let included makefiles determine the
    default goal, as is done by System V Make.

Tue Nov  1 19:03:08 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * variable.c (new_environ): Don't increment VCNT when a variable is
    rejected.

Fri Oct 28 16:54:15 1988  Roland McGrath  (mcgrath at basil.Berkeley.EDU)

    * Version 3.17.

    * rule.c (convert_to_pattern): Don't use the same storage for a name
    in two rules since new_pattern_rule may free this storage when a
    rule is discarded.

    * rule.c (new_pattern_rule): Undid useless change I made Oct 25.

Thu Oct 27 19:17:53 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * Version 3.16.

    * GNUmakefile, Makefile: Fixed a typo in a comment.
    * Makefile: Removed malloc.o from object file list.

    * variable.c: Removed old debugging #define's for xmalloc and
    xrealloc so non-ANSI cpp's won't barf.

    * make.c (main): Made local array for temp file name static so
    compilers that don't do auto aggregate initialization won't barf.

    * read.c: Removed static declaration of copy_dep_chain since it is
    no longer static.

Tue Oct 25 16:59:30 1988  Roland McGrath  (mcgrath at pepper.Berkeley.EDU)

    * rule.c (new_pattern_rule): If we threw out the new rule because it
    matched an old one and OVERRIDE was zero, don't put the freed
    pointer in the chain!

Wed Oct 19 15:07:43 1988  Roland McGrath  (mcgrath at pepper.Berkeley.EDU)

    * Version 3.15.

    * variable.c (expand_function: `sort'): Don't do the sorting and
    writing out if there were no words in the first place.

    * remake.c (remake_file): Only fail with a "no way to make" message
    for a dependency (non-target) file.  If we don't know how to remake
    a target file, pretend it was successfully remade and is very new.

    * remake.c (remake_file): Don't increment `files_remade' for a
    non-target file we don't know how to remake.

    * read.c (record_files): Don't die with "both : and :: entries" for
    a file whose `is_target' flag is not set.

Tue Oct 18 17:24:11 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

    * variable.c (expand_function: `patsubst', `subst'): Free the right
    things!

    * variable.c (expand_function: `subst'): Don't clobber the
    pointer to the end of the second arg and then try to use it!!!

Mon Oct 17 16:44:45 1988  Roland McGrath  (mcgrath at catnip.Berkeley.EDU)

    * variable.c (expand_function: `patsubst'): Don't clobber the
    pointer to the end of the second arg and then try to use it!!!

    * variable.c (expand_function: `word' function): Made it parse its
    second argument correctly.

    * ar.c (ar_touch): Return 1 rather than -1 for on errors.

Sat Oct 15 15:12:16 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * Version 3.14.

    * GNUmakefile: Removed explicit rule for make.dvi since the built-in
    implicit rule now works.

    * rule.c (default_suffix_rules): Fixed .texinfo.dvi rule yet again
    so that it really works, now that parens are counted.

    * remake.c (update_file_1): Set FILE's `updated' flag after calling
    remake_file if it failed or finished immediately.

    * remake.c (update_file): Use the `updated' flag rather than the
    command state to decide if a file was fully considered, and
    therefore might give an "up to date" message.

    * variable.c (expand_function): Made all functions that take more
    than one argument count parens of the appropriate flavor in their
    args and ignore commands nested in parens.

Fri Oct 14 18:35:00 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * read.c (read_all_makefiles): Pass second arg to read_makefile for
    default makefiles.

    * Version 3.13.

    * GNUmakefile: Added an explicit rule for make.dvi since the
    built-in .texinfo.dvi implicit rule is screwed up.

    * rule.c (default_suffix_rules): Added a comment that the
    .texinfo.dvi rule does not work because of an ahem, feature of Make
    that at some point will be fixed--er, enhanced to alleviate this
    difficulty.

    * rule.c (default_suffix_rules): Fixed Texinfo -> DVI rule (again).

    * make.texinfo (Commands: Execution): Documented new competing for
    standard input among children.

    * commands.c (struct child): Added `good_stdin' flag to tell if this
    child has the stdin that doesn't point into nirvana.
    (good_stdin_used): New variable to tell if any child has the good
    standard input.
    (child_handler): Reset `good_stdin_used' if a dead child's
    `good_stdin' flag is set.
    (start_job): Give the new child the good standard input if
    `good_stdin_used' is no set, and set the child's `good_stdin' flag
    appropriately.

    * rule.c (default_suffix_rules): Changed Texinfo -> DVI rule to work
    better (I hope).

    * read.c (read_all_makefiles): Stop reading default makefiles after
    one is found.

    * read.c (read_makefile): Reset `reading_filename' and
    `reading_lineno_ptr' after recursing for an included makefile.

    * GNUmakefile: New GNU Make-specific makefile that does everything
    Makefile does plus distribution stuff, and doesn't contain any hacks
    to try to work with Unix make.

    * Makefile: Removed distribution stuff.

    * make.c (main): Use mktemp to construct the names of temporary
    files used for standard input makefiles.

    * make.c (main): Don't turn standard input into a broken pipe.

    * commands.c (start_job): Keep two extra file descriptors around: a
    good standard input, and a bad one that reads from a broken pipe.
    On the child side of the fork, if there are other children, give
    this one the broken pipe so they won't compete; if this is the only
    one, give it the good standard input.

    * make.h: Declare notice_finished_file.

    * commands.c (execute_file_commands): Use noticed_finished_file
    after waiting for the child when there is only one job slot.

    * remake.c (notice_finished_file): New function to re-check mtime's
    and such things to be done when commands finish.
    (update_file_1): Use notice_finished_file.

    * commands.c (child_handler, execute_file_commands): Use new
    variable `job_slots_used' to record the number of jobs currently
    running, rather than diddling with `job_slots'.
    (execute_file_commands): Increment `job_slots_used' before calling
    start_job and decrement it on failure to avoid race condition.
    If there is only one job slot, wait for the child to finish and
    return its status so commands are run in linear order, as if there
    were no parallelism.

Wed Oct 12 15:59:03 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * remake.c (remake_file): Don't print a "No way to make" message for
    targets whose `dontcare' flags are set.

    * read.c (read_all_makefiles): Set the `dontcare' flag of the
    `struct file' each default makefile added to the chain.

    * file.h (struct file): Add `dontcare' member.

    * read.c (read_all_makefiles): When no default makefiles are found,
    put the names of all those tried in the `read_makefiles' chain so
    they will be updated if possible, giving their `struct dep's'
    `changed' members the value of 0 so we won't care if they cannot be
    found or remade.

    * make.texinfo (Makefiles: Remaking Makefiles): Documented that
    default makefiles will be remade if not found.

    * read.c (read_all_makefiles): If no default makefiles can be found,

    * rule.c (count_implicit_rule_limits), vpath.c
    (construct_vpath_list): Test the existence of a given directory by

    it means the directory really does not exist.

    * dir.c (struct dirdata): Replaced with `struct directory' for
    directories, each containing a chain of `struct dirfiles', one for
    each file (real or impossible).
    (dir_load): Removed.

    already in the hash tables.
    (file_impossible, file_impossible_p, dir_name, print_dir_data_base):
    Use the new directory/file scheme.

    * make.texinfo: Miscellaneous editorial changes and clarifiactions.

    for double-colon files.

    * make.c (main): Put a ".PHONY: /tmp/foo" line in front of temp

    on their `updated' flag, not their state.

    * read.c (read_makefile): Don't check for FILENAME being "-".
    (read_all_makefiles): Set each element of MAKEFILES to the name put
    in READ_MAKEFILES by read_makefile, since read_makefile may free the

    the elements of MAKEFILES again.

    * make.c (main): For each `-f' flag with arg `-' (standard input),
    read standard input into a temp file and pass the temp file's name

    spaces between them.

    * Version 3.10.

    DIRNAME and filename "" if DIRNAME doesn't exist.

    * commands.c (execute_file_commands): Return 0 after start_job
    returns 1 (failure) under the -n flag.

    * remake.c (remake_file): Set the state to `cs_finished' when not
    calling execute_file_commands.

    * remake.c (update_goal_chain): Second arg is now MAKEFILES, nonzero
    meaning to disable -t, -q, and -n for each target unless the target
    was also given on the command-line.

    * read.c (read_makefile): Enter the `struct file's for the makefiles
    added to the `read_makefiles' `struct dep' chain.

    * remake.c (update_goal_chain): Made it not enter the files for the
    goals in the chain.  It will already have been done.

    * rule.c (convert_to_pattern): Null-terminate the names of targets
    and deps of the pattern rules properly.

Fri Sep 30 18:56:20 1988  Roland McGrath  (mcgrath at nutmeg.Berkeley.EDU)

    * read.c (find_makefile): Removed this function.
    (read_all_makefiles): Don't update makefiles, don't diddle with
    pattern rules, don't call snap_deps, etc.  Return a `struct dep'
    chain of all makefiles read.
    (read_makefile): Now takes two args: FILENAME and TYPE, which is 0
    for a normal makefile, 1 for MAKEFILES variable or 2 for an included
    makefile.  Add a `struct dep' containing the name of the makefile
    (as it was found in the search path for type 2s), and TYPE in the
    `changed' member to the global `read_makefiles' chain.

    * make.h, rule.c (displace_pattern_rules,
    add_displaced_pattern_rules): Removed these functions.

    * read.c (read_makefile): Variable-expand the name of an `include'd
    makefile before calling find_makefile on it.

    * file.c (snap_deps): If the `struct file' for a `struct dep'
    already exists, free the `struct dep's `name' member before setting
    it to nil (since this info is in the `struct file').

    * read.c (copy_dep_chain): Made it copy each name rather than
    leaving multiple `struct dep's with the same pointers.

Thu Sep 29 19:08:13 1988  Roland McGrath  (mcgrath at catnip.Berkeley.EDU)

    * make.c (decode_switches): Fixed second decode_env_switches call to
    use correct length of "MFLAGS" (6, not 5).

    * read.c (read_makefile): Don't stop reading when readline returns
    zero lines read.  Only stop when the stream reaches EOF.  This makes
    it recognize the last line of a makefile without a newline.

    * remake.c (remake_file): If we don't know how to make FILE, set its
    command state to `cs_finished'.

    * remake.c (update_file): Don't write the "up to date" message if
    update_file_1 returned a nonzero status.

Wed Sep 28 16:30:07 1988  Roland McGrath  (mcgrath at catnip.Berkeley.EDU)

    * commands.c (child_handler): Set the `update_status' member
    properly for ignored errors.

    * rule.c (convert_to_pattern): Made it not care about if the target
    suffix comes before the source suffix in the .SUFFIXES list.

    * make.texinfo: Misc editorial changes.

    * Version 3.09.

    * commands.c (struct child): New member `command_ptr' to hold the

    for `commands' and `command_ptr' members.

    * make.c (decode_env_switches): Skip past an invalid letter (instead

    environment for this child.
    (execute_file_commands): Get a new environment from new_environ and
    put in the the new `struct child's `environ' member.
    (child_handler): When freeing a child, free its `commands' member, the
    elements of its `environ' array and its `environ' member itself.
    (start_job): Set `environ' to the child's `environ' member before
    exec'ing the command.

    * variable.h, variable.c (new_environ): Made it return the new
    environment, not putting it in `environ'.

    * remake.c (update_file): Don't give a "is up to date" message
    unless no files were remade and the state went from `cs_not_started'
    to `cs_finished', so repeat calls to finish jobs won't get the message.

    * make.c (main): Use wait_for_children rather than child_handler.

    * commands.c (wait_for_children): New function to block waiting for
    children, insuring that child_handler is not called recursively.
    (execute_file_commands, kill_children): Use wait_for_children.

    * commands.c (child_handler): Start up additional commands in a
    sequence after an ignored error.

    * remake.c (update_file): Don't print "`foo' is up to date" messages
    when update_file_1 returns while commands are executing.

    * remake.c (update_file_1): Pass the file name to name_mtime, not
    the bloody `struct file', dammit!!

    * commands.c (child_handler): Print out the "*** ..." error message
    when not under -i.  (I somehow forgot this.)

    * remake.c (update_file_1): Use name_mtime rather than file_mtime to
    re-get the mtime of a file whose commands have finished.

    * make.c (command_switches, decode_switches, decode_env_switches):
    Make all switches that take string args allow them right after the
    switch letter.

    * commands.c (child_handler): Check for a child being the `shell'
    function's command returning and set the global variable for
    expand_function to check.

    * variable.c (expand_function): For the `shell' function, instead of
    waiting for the child shell ourselves, let child_handler do it and
    loop around waiting for something to happen.

    * make.c (print_version): Made the copyright year static, not dynamic.

    * make.h, make.c: Remove construct_argv function.

    * remake.c (update_file_1): If deps are running, set state to
    `cs_deps_running' and return 0.  If deps are done, run commands.

    * commands.c (child_handler): Made it delete non-precious targets
    killed by fatal signals.

    * make.texinfo: Documented parallelism.

Fri Sep 23 16:52:27 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

    * remake.c (update_file_1): Don't return if FILE's state is

    starting a new job to run file commands.

    * commands.c (start_job): Made it set the state to `cs_running'.

    goal-making loop.

    * commands.c (child_handler): When commands finish, set the
    corresponding file's `update_status' and `updated' flags as
    appropriate, and reset the modtimes of the file and any `also_make'
    files it has.

    * remake.c (remake_file): Don't re-set `last_mtime' and set `updated'.

    * commands.c (fatal_error_signal): Don't swallow all the children
    with a loop around `wait ((union wait *) 0)'!!!

    (construct_makeflags, decode_switches, decode_env_switches):
    Handle`positive_int'-type switches.

    * glob.c (glob_vector): Rename local variable `vector' to `VeCtOr'.
    This is said to avoid a conflict with some system's global `vector'
    variable.

    * variable.c (expand_function): Made the `shell' function use
    construct_command_argv and do its own child control and piping.

    * make.c (main): Turn standard input into a broken pipe after
    reading in all makefiles (the last time it will be needed).

    * commands.c (struct child): Remove `pipe_fd' member.  We don't use
    pipes any more.
    (start_job): Return 0 for success, 1 or failure (rather than void).
    Don't use pipes.  Don't turn the child's stdin into a broken pipe.
    (child_handler): Print "*** Error" messages when necessary.

    `noerror' members to keep track of info about a command thread.
    (start_job): New function to start a job and update the argument
    `struct child' to reflect its status.
    (execute_file_commands): Merged run_file_commands back in.
    Made it use new start_job function.

    * rule.c (freerule): Don't free the `struct commands' of the
    discarded rule.  It may be used in more than one place.

    * commands.c (execute_command_line): Made it not try to delete the
    possibly partly-made file.  The child_handler function will do this.
    (fatal_error_signal): Ditto + call kill_children.

    * make.h: Declare job_slots.

    * make.c (main): Collect goals in a dep chain and run through this
    chain waiting for a child, eliminating finished goals, updating all
    remaining goals, and quitting if they fail and not -k.

    * commands.c (child_handler): If called with SIG < 0, - SIG is the
    max number of children to bury.

    * commands.c (child_handler): If called with SIG as zero,
    block waiting for running children.
    (kill_children): Call child_handler with zero rather than SIGCHLD.

    * remake.c (update_file_1): Use the `command_state' member of FILE
    and its dependencies to determine what commands are running, what to
    do, etc.  If commands or dep commands are running when we are

    time we were called, return their status.

    * commands.h: Declare kill_children.

    * commands.c: Define `struct child' to keep track of child
    processes, with the chain in `children'.
    (child_handler): New function to catch child-termination signals
    (SIGCHLD, or SIGCLD for USG), store the returned status in the
    appropriate structure, take the now-obsolete `struct child' out of
    the chain, and free its storage.
    (execute_file_commands): Put all of the stuff invloving running the
    commands into new function run_file_commands.  Execute_file_commands
    now does process management for the commands, while
    run_file_commands (which is run in a subprocess) runs the commands.
    (kill_children): New function to kill all running children by
    sending them signal SIG.  If there are any children still living
    after they are all sent SIG, they are all sent SIGKILL.

    * make.c (main): Catch SIGCHLD (SIGCLD for USG) with child_handler.

    * commands.h: Declare child_handler function.

    * commands.c (execute_file_commands): Check the `command_state'
    member of FILE and return 0 if it is `cs_running' or
    `cs_deps_running' and return the stored status if it is `cs_finished'.

    * commands.c (execute_command_line): Add `$' to the list of
    characters special to the shell.

    * Makefile: Put tags files in the tarfile.

    * read.c (read_makefile): Get the modtime of the makefile via a stat
    call so that a later file_mtime call won't do VPATH search for it.

    * read.c (read_makefile): Don't turn off -t and -q if the makefile
    was a command-line target.

    * make.c (main): Enter command-line targets as files and set their
    `cmd_target' members.

    * file.h (struct file): Added `cmd_target' member.

    * read.c (read_makefile): Temporarily turn off -t and -q while
    updating makefiles.

    * make.c (main): Don't use arg 0 from other_args (which is now
    argv[0]; i.e., the program's name).

    * read.c (read_makefile): Only return nonzero if commands were
    actually run to remake the makefile.

    * remake.c (update_file_1): Set FILE->updated to -1 if no commands

    bad args if it tried to expand other_args->list.

    * read.c (read_all_makefiles): Made it not look at the `MAKE'
    variable, just use argv[0].

    * read.c (rerun_make): New function to re-exec make.

    * make.c (construct_makeflags, construct_argv): New functions to
    construct the `MAKEFLAGS' variable and to construct an arg list from
    parsed info.

    * read.c (read_makefile): New arg UPDATEIT, if nonzero, says to
    update the makefile as a target before reading it in.  When reading
    included makefiles, pass this as zero.  Now returns nonzero if the
    makefile was updated, zero if not.
    (read_all_makefiles): Pass a nonzero UPDATEIT arg to read_makefile
    for all default and -f makefiles and all makefiles from the
    `MAKEFILES' variable.  If any of the makefiles has changed, re-exec
    self to re-read them.

    under -p.

    * commands.c (execute_file_commands): Allocate one byte for each of

    if it started with `./' and was therefore not quite the same as in
    the `struct file'.

    * read.c (record_files): If commands were specified twice, the error
    message specifies in what files and at what line numbers.

    * make.c (main): If any of the signals we usually fatal on were
    ignored by the parent (probably a shell), ignore them.

    * make.c (main): Print version info for -v, -p, or -d.
    (print_data_base): Don't print version info.  It will be done in main.

    * variable.c: Increased number of hash buckets to 257.

    * file.c: Increased number of hash buckets to 1007.

    * rule.c (count_implicit_rule_limits): Moved comptation of
    `maxsuffix' to convert_to_pattern, since that function uses
    `maxsuffix', and must be called before count_implicit_rule_limits.

    * rule.c (pattern_search): If an existent (non-intermediate)
    dependendency was found via a terminal rule, set its
    `tried_implicit' flag, so it will never have implicit rule search done.

    * glob.c: Bug fix to avoid alloca(0).

    * arscan.c: USG and Sun386i fixes.

Thu Sep 15 19:40:26 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

Wed Sep  7 14:20:39 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)

    * make.c (decode_switches): Fixed bug wherein a bad option would
    give a useless error message and loop forever.

    gets filled in with a malloc'd buffer containing the piped stdout of
    the command.
    (execute_file_commands): Use above (pass nil).

Mon Sep  5 17:03:49 1988  Roland McGrath  (mcgrath at hecuba.Berkeley.EDU)

    * Makefile: Added copyright notice.
    Added a comment about defining `NO_MINUS_C_MINUS_O' if necessary.

    * Version 3.05.

    * read.c (read_all_makefiles): Made it try default makefile
    `GNUmakefile' before others.

    * make.texinfo: Added new-style Texinfo header thingies.

Sat Sep  3 18:09:39 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * Version 3.04.

    * make.texinfo (Chained Rules): Added a @cindex about using
    .PRECIOUS to preserve intermediate files.

    * remake.c (update_file_1): Made it not just return before executing
    commands under -p.

    * rule.c (default_pattern_rules, default_variables): Made it use
    `$(AR)' for `ar r' (to put files in archives).

    * vpath.c (build_vpath_lists): Made it recursively expand the

    the comma in an `ifeq' using the `(a,b)' syntax.

    * rule.c (count_implicit_rule_limits): Made it not crash if a
    pattern rule dep begins with `/'.

Sun Aug 28 15:51:12 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

    * make.texinfo: Clarified that the arg to the `origin' function is a
    variable *name*, not a reference.

    * make.texinfo: Clarified that both -Idir and -I dir are allowed.

Sat Aug 27 13:49:28 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * remake.c (remake_file): Made touching phonies work right.

    * make.texinfo: Removed reference to `RANLIB' variable.

    * Version 3.03.

    * variables.c (expand_function): Added `origin' function.
    * make.texinfo: Documented same.

    * read.c (record_files): Made double-colon entries work.

Sat Aug 20 21:09:39 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (collapse_continuations): Bug fix from RMS.

    * rule.c (install_default_pattern_rules): Made it set the
    `in_use' flag of the created rules to zero, rather than letting
    it be random garbage.

    * rule.c (pattern_search): Fixed putting `also make' targets into
    file strucutres.

    * read.c (record_files): Fixed bug which made double-colon entries
    make it read off into space.

    * make.c (decode_switches): Made it understand `ignored' switches
    rather than dumping core.

Sun Aug 14 16:49:00 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * read.c (read_makefile): Made `include' filenames be
    variable-expanded.

    * read.c (read_makefile): Fixed an error message.

    * read.c (read_makefile): Made it accept ^L's as whitespace.
    * make.c (next_token, end_of_token): Ditto.

    * vpath.c (vpath_search): Fixed it so that the general VPATH (from
    the variable) is always checked, even if a selective VPATH (from a
    directive) matched the filename.

Sat Aug 13 14:20:46 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (decode_switches, main): Made the command switches be
    processed from a table of switches, variables, and types.  No
    functions are passed argc and argv any more.  They are passed arrays
    of strings they need to process.
    * read.c (read_all_makefiles): Made it take an array rather than
    argc and argv.
    (construct_include_path): Ditto.

    * make.c (collapse_continuations): Made it work right (I hope).

    * make.texinfo: Minor editorial changes.

    * read.c (read_makefile): Minor speed improvement by freeing and
    then mallocing something rather than reallocing it to avoid the
    unnecessary bcopy.

Thu Aug 11 00:10:43 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.texinfo: Fixed some unquoted @'s.

    * make.texinfo: Documented multiple-target pattern rules.
    Miscellaneous minor editorial changes and corrections.

    * make.texinfo (Implicit: Catalogue of Rules): Removed the list of
    variables.  That's what the next section is for.
    (Implicit: Implicit Variables): Made it agree with reality.

Wed Aug 10 00:55:39 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * variable.c (print_variable_data_base): Fixed bug which made -p
    dump core.  (This was a really idiotic bug.)

    * rule.c (pattern_search): Fixed a bug which made it make the
    `also_make' member of the file in question nil if the first of
    the successful rule's targets was the matching one.
    Made it use only as much storage as necessary in the `also_make'
    member.
    (create_pattern): Made it use only as much storage as necessary in
    the `lens' and `suffixes' members of the created rule.

    * remake.c (library_file_mtime): Made it `static'.

    * file.c: Added a declaration for `errno', which is declared in some
    <errno.h>'s, but not all.

    * file.h (struct file): Added `also_make' member for multiple-target
    implicit rules.
    * rule.c (pattern_search): Made it put the names of files updated by
    the given file's commands in its `also_make' member.
    * remake.c (update_file_1): Made it mark the files in a file's
    `also_make' member as updated when the file is updated.

    define a variable with the name of the whole definition when there
    was no space before the = or :=.

    * make.texinfo (Features): Made the changes which were made in RCS
    revision 2.7 but somehow lost since then.  Added -W.

Tue Aug  9 10:04:50 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * variable.h: Added `o_default' to `enum variable_origin'.
    * variable.c (print_variable_data_base): Made it print the origins of
    the variables.
    * rule.c (install_default_pattern_rules): Made it define the default
    variables with origin `o_default'.

    * make.texinfo: Documented -W.

    * make.c (decode_switches, main): Added the -W flag to give files a
    time-stamp of now, for a `what if' effect when used with -n.

    * commands.c (print_commands): Made it say `(built-in)' for commands
    that are built into the default ruleset.

    * read.c (record_file): Made .SUFFIXES get its deps frontwards (again).
    * rule.c (set_default_suffixes, convert_to_pattern): Made it read
    .SUFFIXES's deps frontwards, so the converted rules will not be in
    reverse order.

    * rule.c (new_pattern_rule): Fixed a bug wherein it would keep
    searching after it had removed a matching rule and ended up diddling
    with freed storage.

    * rule.c (freerule): Made it take the given rule off the chain.
    (new_pattern_rule, count_implicit_rule_limits): Use freerule to
    remove rules from the chain.

    * vpath.c (construct_vpath_list): Made it return after cleaning out
    all previous searchpaths when given a nil DIRPATH arg, so it won't
    go into the construction code and dump core dereferencing a nil
    pointer.

    * variable.c (patsubst_expand): Fixed a bug which made it not match
    correctly and sometimes dump core.

Mon Aug  8 16:35:48 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * rule.c (default_suffix_rules): Made the .texinfo.dvi rule remove
    the files used in the comparison to determine whether or not a
    second TeX run is necessary.

    * make.texinfo: Fixed some overfull TeX hboxes.

    * make.texinfo (Implicit: Catalogue of Rules): Fixed a Texinfo error.

    * rule.c (create_pattern_rule): Fixed bug wherein index was not
    being passed its second arg.

    * read.c (getline): Merged back into readline.

    * rule.c (default_suffixes, default_suffix_rules,
    default_variables): Added .texinfo.info rule.
    * make.texinfo (Implicit: Catalogue of Rules): Documented
    .texinfo.dvi and .texinfo.info rules.

    * make.texinfo (Top): Changed `last updated' date to be correct (for
    the last time it was updated, not today).  Changed `for version
    3.00' since it's not going to be called that.

Sat Aug  6 19:51:10 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * commands.c (print_commands): Added this function to print the
    contents of a `struct commands' for -p.
    * rule.c (print_rule_data_base): Use above.
    * file.c (print_file_data_base): Ditto.

    * rule.c (count_implicit_rule_limits, new_pattern_rule,
    install_pattern_rule, print_rule_data_base): Made it understand the
    changed `struct rule' and act accordingly.
    (freerule): Added this function to free all the storage used by a rule.

    * rule.c (pattern_search): Made it grok multiple targets of pattern
    rules.  The matching is done properly, but at present, only the
    matching pattern's target is used to give deps and commands.

Fri Aug  5 18:00:29 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * rule.c (struct rule): Changed name, namelen, and patsuffix members
    to targets, lens, and suffixes, which are arrays, for multiple targets.
    (create_pattern_rule): Now takes first arg TARGETS, a nil-terminated
    array of targets, rather than a single target and patsuffix pointer.

    * read.c (record_files): If it finds an implicit pattern rule, it
    collects all the targets into an array and passes the whole thing to
    create_pattern_rule.  If there are non-pattern targets, it is a
    fatal error.

Tue Aug  2 15:06:38 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (readline): Split backslash-newline checking from reading
    and buffer-expanding.
    (getline): Created to do the reading and buffer-expanding formerly
    done in readline.

    * rule.c (pattern_search): Made it reject nonterminal match-anything
    rules when a specific rule has matched, rather than rejecting
    terminal match-anything rules in this case.

    * rule.c (convert_to_pattern): Fixed a bug caused when the change to
    make it only recognize two-suffix rules whose target suffixes
    precede their dependency suffixes which made it work in the opposite
    direction (even worse than it started out).

    * rule.c (pattern_search): Made it reject nonterminal match-anything
    rules as intermediate targets when searching for both real and
    intermediate dependencies, rather than only when searching for
    intermediate ones.

Sun Jul 31 00:33:56 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * rule.c (convert_to_pattern): Made it only recognize two-suffix
    rules whose target suffix comes before the dependency suffix in the
    .SUFFIXES list.

    * variable.c (define_automatic_variables): Made all automatic
    variables be defined with origin `o_automatic'.

    * variable.h: Added `o_automatic' to `enum variable_origin'

    * file.c (remove_intermediates): Made it not print an error message
    if the error was that the file does not exist.

    * rule.c: Removed `recursive' member from `struct rule'.

    * remake.c (library_file_mtime): Made it not use the directory hash
    functions, as reading in and hashing /usr/lib and /lib is slow and
    most likely unnecessary.

    * remake.c (remake_file): Changed message from ``No specification
    for making'' to ``No way to make'' so it will be short enough that
    most filenames will fit on a line.
    Made it look at the `recursive' member of the `struct commands',
    rather than of the `struct file' (which no longer has one).

    * commands.c (execute_file_commands): Made it look at the
    `recursive' member of the `struct commands', rather than of the
    `struct file' (which no longer has one).

    * file.h: Removed `recursive' member from `struct file'.

    * commands.h: Added `recursive' member to `struct commands'.

    * dep.h: Removed unused `quotedparen' member from `struct nameseq'
    and `struct dep'.

    * read.c (dequote): Removed this function.
    (multi_glob): Removed reference to `quotedparen' member of
    a `struct nameseq' and calls to dequote.

    * read.c (record_files): Made it set the stem for $* for all static
    pattern rules, not just those with commands given at that time.
    Removed check for recursive commands.
    Made it check for pairs of .SUFFIXES dependencies to reject as
    default goals as well as single ones (that don't start with dots).
    (read_makefile): Added checks for recursive commands to set
    the `recursive' flag in the `struct commands'.

Sat Jul 30 15:47:23 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (find_next_token): Made the LENGTHPTR arg optionally nil.

    * make.c: Removed `files_made' variable which is defined static in
    remake.c and used only there.
    (main): Cleaned up somewhat.
    (decode_switches): Cleaned up a bit.  Made an unknown option be a
    non-fatal error.
    (decode_env_switches): Made LEN arg unsigned.  Cleaned up.
    (print_version): Made it say ``see the source'' rather than ``see
    the source file'', since there is more than one.

    * file.h: Made `num_intermediates' declared unsigned.

    * file.c: Made `num_intermediates' variable unsigned.
    (remove_intermediates): Removed unused FORMAT arg.
    (enter_file): Made it handle double-colon files properly, adding the
    new entry as the old entry's prev pointer.

    * dir.c: Re-indented the `struct dir' definition to be right.
    (dir_load): Cleaned up slighty.
    (file_exists_p): Removed comment saying we could use `access', since
    that is a bad idea (except for setuid programs).  Cleaned up slightly.

    * commands.c: Changed some comments slightly.
    (execute_file_commands): Cleaned up a bit.  Changed some comments,
    added others.  Moved freeing of storage for $^ and $? to the same
    place as for the other automatic variables.
    (execute_command_line): Made `#' trigger a shell.
    Added some comments.  Cleaned up a bit.  Put all the special chars
    that trigger shells into an array easily changeable at the top.

    * ar.c: Added comments explaining each function.
    (ar_scan_1): Merged into ar_member_date.
    (ar_member_date): Changed call to ar_scan_1 to the body of that
    function.
    (ar_member_date_1): Simplified to a ?: expression rather than an
    if-else statement.
    (ar_member_touch): Changed error handling around a bit.
    None of these errors are fatal now.

    * variable.c (subst_expand): Added a new arg BY_WORD, to do substs
    only on full words.
    (patsubst_expand): Fixed bug which made calls whose patterns
    contained no `%' to not work correctly, by using above.
    (variable_expand): Pass extra arg to `subst_expand'.

    * variable.c (expand_function): Fixed bug which made `foreach' calls
    with one-word lists run off into never-never land.

Fri Jul 29 20:12:36 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * variable.c (expand_function): Made a very minor speed improvement
    by avoiding an unnecessary strlen call.

Wed Jul 27 16:01:47 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * rule.c (default_suffixes): Rearranged the list somewhat; added
    `.el' and `.elc' to speed things up (especially when building
    Emacs), for the same reason `.h' is there.

    * read.c (record_files): Changed `lineno' from `long' to
    `unsigned int'.

Sun Jul 24 02:15:30 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * variable.c (expand_function): Eliminated use of `wstok'
    because it is non-reentrant and unreliable.
    Fixed a minor bug which would cause something not to be freed.
    * make.c (wstok): Removed `wstok' because it is no longer used.

    * variable.c (expand_function): Made `foreach' function put
    spaces between output texts like it's supposed to.

Sat Jul 23 17:32:55 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * rule.c (default_suffixes, default_suffix_rules): Added rule
    to make %.dvi from %.texinfo.

    * dir.c (print_dir_data_base): Made it say a bit more.

Fri Jul 22 23:13:16 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * make.c (print_data_base): Split this function up into one
    for each thing.
    * variable.c (print_variable_data_base): One of the above.
    * rule.c (print_rule_data_base): Ditto.
    * file.c (print_file_data_base): Ditto.
    * dir.c (print_dir_data_base): Ditto.

    * rule.c (install_pattern_rule): Fixed a bug which caused the
    terminal and recursive flags to always be zero for rules
    entered by this function.

    * make.texinfo (Rules: Double-colon): Added a paragraph
    explaining the purpose of double-colon rules.

    * make.texinfo (Implicit: Catalogue of Rules): Updated to
    reflect new C++, TeX, Web, and Texinfo rules.  Other slight
    editorial changes.

    * commands.c (execute_file_commands): Fixed a bug wherein
    random memory could get written for files with no deps.

Wed Jul 20 19:30:31 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * read.c (readline): Fix bug wherein it would not recognize a
    backslash-newline if the buffer filled up and was enlarged
    right before reading the newline.

Tue Jul 19 19:55:02 1988  Roland McGrath  (mcgrath at chilli.Berkeley.EDU)

    * read.c: Added default suffix rules for .cc (using $(C++),
    which defaults to `g++', and $(C++FLAGS)), .tex, .dvi, .web
    and .cweb (using $(TEX), $(WEAVE), $(TANGLE), $(CWEAVE) and
    $(CTANGLE)).

Sat Jul 16 21:24:28 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * Made error formats use %u rather than %ld for line numbers,
    which are now unsigned int's rather than long's.

    * read.c (conditional_line): Fixed some bugs caused by use of
    unsigned int rather than int in one place.

    * read.c (conditional_line): Put the info about active
    conditionals in a struct.
    (read_makefile): Make a new struct of info about conditionals
    for included makefiles and restore the old one after the
    included makefile has been read.

    * read.c (read_makefile): Don't try to read a makefile with
    name "" after giving an error message because an `include'
    directive gave no filename.

    * read.c (read_makefile): Give an error message for
    non-whitespace text after the filename in an `include' directive.

    * make.c (error): Take five args, like `fatal'.  It managed to
    lose with only two.  Is there a better way to do this without vfprintf?

    * read.c (read_makefile): Commands consisting of only
    whitespace are not the same as no commands.  I thought I'd
    fixed this bug months ago; it seems to have come back.

    * make.c (collapse_continuations): All whitespace around a
    backslash-newline combination is turned into a single space.

    * Added COPYING file and copyright notices to all files.

    * make.texinfo (Running: Goals): Fix a typo.

    * read.c (do_define): Take an arg for the origin of the
    variable being defined.
    (read_makefile): Grok `override define'.

    * make.texinfo (Variables: Override Directive, Defining):
    Document the `override define' combination directive.

    * ar.c (ar_member_date): Make a 0 return from `ar_scan' return
    (time_t) -1 (nonexistent file), rather than (time_t) 0, which,
    when put in the `struct file', makes `file_mtime' try to get
    the mtime over and over again.

    * variable.c (pattern_matches): Fix a bug that made patterns
    not beginning with `%' never match.

Fri Jul 15 21:01:44 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

    * Took Make out of RCS.

    * Split the monolithic `make.c' into several smaller files.
