Sat May 22 17:45:19 1993  Noah Friedman  ([e-mail])

        * Version 1.4 released.

Thu May 20 20:25:45 1993  Jim Blandy  ([e-mail])

    * acgeneral.m4 (AC_IDENTITY): New function.
    (AC_DEFINE_UNQUOTED): Use it to fix this; due to a
    misunderstanding of m4, this was using its first argument as
    the definition.

Thu May 20 09:21:55 1993  Jim Meyering  ([e-mail])

        * acspecific.m4 (AC_ALLOCA) [find_stack_direction]: Return the
    value from the recursive call.  If it worked before, it was by luck.
    From Bruno Haible <[e-mail]>.

Tue May 18 23:40:21 1993  Noah Friedman  ([e-mail])

        * acspecific.m4 (AC_STDC_HEADERS): Require AC_PROG_CPP.

Mon May 17 18:01:09 1993  Karl Berry  ([e-mail])

        * acgeneral.m4 (AC_OUTPUT): Use variables gen_files and
        gen_config in the loop that generates the output (Make)files,
        instead of hardwiring the filenames.

Sat May 15 17:23:19 1993  Roland McGrath  ([e-mail])

    * autoconf.sh: Accept `-' to mean read stdin as input.
    * autoheader.sh: Likewise.

Fri May 14 12:41:02 1993  Noah Friedman  ([e-mail])

        * autoheader.sh, acspecific.m4 (AC_PREPARE): If `LANG' environment
        variable is set, reset its value to `C'.  This is so `tr [...]'
        works more portably.

Thu May 13 22:56:20 1993  Paul Eggert  ([e-mail])

    * acspecific.m4 (VOID_CLOSEDIR): Test closedir instead of assuming
    that it works.  E.g. dynix closedir yields garbage, but has no
    prototype.  Presumably Xenix closedir had the same problem, so
    stop special-casing it.

Wed May 12 20:25:36 1993  Jim Meyering  ([e-mail])

    * acconfig.h: Add HAVE_LONG_DOUBLE.

Wed May 12 15:07:36 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_DEFINE_UNQUOTED): New macro.

    * acgeneral.m4 (AC_FUNC_CHECK): Include ctype.h instead of stdio.h.
    We want it only to define __stub_* in glibc.  Using stdio.h lost
    when it contained a conflicting prototype for $1; ctype.h has fewer
    prototypes.

    * acconfig.h: Add GETGROUPS_T.

    * acspecific.m4 (AC_PROG_RANLIB): Use : instead of @: for no-op.
    Some braindead make does bizarre magical things with @ in variables.

Mon May 10 14:24:27 1993  Noah Friedman  ([e-mail])

        * acspecific.m4 (AC_HAVE_POUNDBANG): New feature.

        * acgeneral.m4 (AC_OUTPUT): Add more backslashes to character class
        in DEFS filter (sigh).

Sun May  9 14:04:31 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_DEFINE_QUOTE): No AC_QUOTE_SED (was innermost).
    (AC_HEADER_EGREP, AC_PROGRAM_EGREP, AC_TEST_CPP): Put a \ before
    $DEFS in string to be evalled.
    (AC_OUTPUT): Run DEFS through a sed filter that quotes things in it
    from sed (woo woo!) before writing it into config.status.

    * acspecific.m4 (AC_ALLOCA): Use AC_PROGRAM_EGREP to test for [CRAY
    && !CRAY2], instead of AC_TEST_PROGRAM.  No need to run a program
    for this.

    * acgeneral.m4 (AC_PROGRAM_CHECK): Extract the first word of $2
    when looking for it in PATH, so it can be a program name with args.
    Omit default assignment if $4 is empty.
    Only write verbose msg if $1 was set nonempty.
    * acspecific.m4 (AC_PROG_YACC): Pass 'bison -y' (quoted like that)
    in list to AC_PROGRAMS_CHECK.  Don't test for bison later to add -y
    flag.

Sat May  8 00:23:58 1993  Jim Meyering  ([e-mail])

    * acgeneral.m4 (AC_REPLACE_FUNCS): Add a trailing newline in
    code for AC_COMPILE_CHECK.  Otherwise it got spurious failures.

    * acspecific.m4 (TIME_WITH_SYS_TIME): New macro.

    * Makefile.in (dist): Depend on Makefile.  Use gzip instead
    of compress.  Link files individually instead of en masse;
    if a link fails, use `cp -f' on the losing file.

    * acspecific.m4 (AC_ALLOCA): Define CRAY_STACKSEG_END (the
    name of a function used in alloca.c) for CRAY-1, CRAY X-MP,
    and CRAY Y-MP.

Fri May  7 15:56:26 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_GETLOADAVG): Check for mach/mach.h, but don't
    disable nlist checks if found.

Fri May  7 04:59:25 1993  Noah Friedman  ([e-mail])

        * acspecific.m4 (AC_PROG_INSTALL): Don't look for `install' in
          /usr/ucb.

Thu May  6 20:41:35 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_FUNC_CHECK): The test program should choke on
    #ifdef __stub___$1 as well.
    (AC_REPLACE_FUNCS): Make the test program choke on stubs.

Wed May  5 20:43:13 1993  Roland McGrath  ([e-mail])

    * autoconf.sh ($infile existence check): Fixed test for
    nonemptiness of $print_version to not always be true.

Wed May  5 17:22:42 1993  David J. MacKenzie  ([e-mail])

    * acgeneral.m4 (AC_PREFIX, AC_PROGRAM_CHECK), acspecific.m4
    (AC_PROG_INSTALL): If IFS wasn't set initially, give it a
    normal default value.  Happens on LynxOS (x86), says
    Pete Klammer <[e-mail]>.

Wed May  5 13:22:52 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4: Undefine the `shift' builtin.

    * acspecific.m4 (AC_PROG_YACC): Use AC_PROGRAMS_CHECK to check for
    both bison and yacc, instead of two AC_PROGRAM_CHECK uses.

    * autoheader.sh ($# -eq 0): Set var $tmpout to name of temp file,
    send stdout there instead of config.h.in.
    (just before exit): If $# -eq 0, then move $tmpout to config.h.in
    if $status -eq 0, or remove $tmpout otherwise.

    * acspecific.m4 (AC_STRCOLL): Rewritten to use a test program that
    verifies that `strcoll' does vaguely reasonable ordering.

Tue May  4 19:59:00 1993  Jim Meyering  ([e-mail])

    * acspecific.m4 (AC_LONG_DOUBLE): Don't explicitely echo
    `checking for long double'.

    * acgeneral.m4 (AC_FUNC_CHECK): Remove spurious `#endif' line at end.

    * acgeneral.m4 (AC_WITH): Fix reversed args to patsubst.
    Test $with_FOO, not $FOO.

Wed Apr 21 18:14:19 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_QUOTE_TOKEN): New macro.
    (AC_DEFINE_QUOTE): Use it.

Tue Apr 20 18:02:46 1993  Noah Friedman  ([e-mail])

        * acspecific.m4 (AC_DECLARE_YYTEXT): Guess name of lex output file
        and do AC_SUBST of `LEX_OUTPUT_ROOT'.
        Add `dnl' after calling some autoconf macros.

Mon Apr 19 15:46:24 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_MINUS_C_MINUS_O): Do each compile a second time
    after testing for the existence of the output.  Some compilers
    refuse to overwrite an existing .o file with -o, though they will
    create one.

    * acspecific.m4 (AC_DECLARE_YYTEXT): Changed lex input to two lines
    of "%%", not just one.

Sat Apr 17 17:26:12 1993  Jim Meyering  ([e-mail])

    * acgeneral.m4 (AC_COMPILE_CHECK): Don't print `checking for ...'
    message if first argument is empty.

Sat Apr 17 01:18:41 1993  Noah Friedman  ([e-mail])

        * acspecific.m4 (AC_PID_T): provide self.

    * acgeneral.m4 (AC_REPLACE_FUNCS): Print a message under --verbose.

    * acgeneral.m4 (AC_HAVE_LIBRARY): Use m4's patsubst and translit
    instead of running sed and tr at runtime.

    * acconfig.h: Add STACK_DIRECTION.

Wed Apr 14 17:08:47 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_ALLOCA): If we chose alloca.c, run a test
    program to define STACK_DIRECTION.

Mon Apr  5 19:02:52 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_LONG_FILE_NAMES): Put test inside a for loop on
    several directories: . /tmp $prefix $exec_prefix.  Define
    HAVE_LONG_FILE_NAMES iff long names win in all those directories.

Sun Apr  4 18:38:23 1993  Roland McGrath  ([e-mail])

    * Makefile.in (%.info): Removed pattern rule.
    (autoconf.info, standards.info): New rules.

Wed Mar 31 12:45:59 1993  Jim Meyering  ([e-mail])

    * acgeneral.m4 (AC_DEFINE): Put single quotes around definition
    that is echoed with --verbose.  AC_DEFINE(MVDIR, "$(libdir)/mvdir")
    was generating losing code.

Mon Mar 29 15:44:24 1993  David J. MacKenzie  ([e-mail])

    * acspecific.m4 (AC_STDC_HEADERS): Add a missing pair of [quotes].

Mon Mar 29 14:54:00 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_DECLARE_YYTEXT): Change sed regexp so it won't
    match other identifiers beginning with `yytext'.

Sat Mar 27 00:11:16 1993  Paul Eggert  ([e-mail])

    * acspecific.m4 (AC_CONST): Detect broken AIX XL C 1.2.0.0 compiler.

Thu Mar 25 19:54:50 1993  David J. MacKenzie  ([e-mail])

    * acspecific.m4 (AC_CONST): Remove single quotes from the C
    program; they produce shell syntax errors.

    * acgeneral.m4 (AC_DEFINE): Add a newline after "}" to prevent
    commands following on the same line of configure.in from
    generating shell syntax errors.

    * acgeneral.m4 (AC_COMPILE_CHECK): Use explicit return types
    to avoid warnings.
    (AC_TEST_CPP): Add parens to force redirection order.
    (AC_OUTPUT): Allow hostname to return bogus exit status.
    From Jean-loup Gailly <[e-mail]>.

Mon Mar 22 16:53:01 1993  Roland McGrath  ([e-mail])

    * autoheader.sh: Likewise.
    * Makefile.in (M4): Define new variable.
    (autoconf.conf, %.conf): Use it.
    (editsh): New variable: sed command to replace @datadir@; also
    replace @M4@ with $(M4).
    (autoconf, autoheader): Use $(editsh) instead of explicit sed command.

Mon Mar 22 13:08:10 1993  Jim Meyering  ([e-mail])

    * acspecific.m4 (AC_CONST): IBM's /bin/cc under AIX-3.2 on an rs6000
    rejects attempts to modify *any* member of a struct that has a
    member declared like `const int *ap[2]'.

    Updated usage string.

        * autoconf.texi: Documented --macrodir option and its effects for
        both scripts.

Tue Mar 16 09:10:48 1993  Jim Meyering  ([e-mail])

    * acspecific.m4 (AC_CONST): Sun's SC1.0 ANSI compiler (acc) won't
    increment a `const int *' pointer declared through a typedef.

Mon Mar 15 16:08:42 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_PARSEARGS): Grok `--verbose' flag; set verbose=yes.

Sun Mar 14 18:19:21 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_PROG_INSTALL): Choose `installbsd' if we find
    it, in preference to `install'.

    * acspecific.m4 (AC_CONST): Add a check for `const int *foo' not
    allowing modification of FOO (not *FOO).

Fri Mar 12 15:27:53 1993  Roland McGrath  ([e-mail])

    creating it.

Thu Mar 11 12:57:53 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_DEFINE): Surround defn with { and }.

    * acgeneral.m4 (AC_OUTPUT_HEADER): Split up $SEDDEFS into smaller
    chunks, since some shells can't handle large here documents.
    We write several commands in config.status to create conftest.sed
    in pieces.

Mon Mar  8 14:40:53 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_WITH): Don't echo anything.

    massage $1.

    * acspecific.m4 (AC_DIR_HEADER_CHECK): #include <sys/types.h>
    before the header we are testing.

    * acgeneral.m4 (AC_DEFINE): If $2 is empty, echo "defining $1 to be

Tue Mar  2 01:06:25 1993  Noah Friedman  ([e-mail])

        * autoheader.sh: Don't use /p1/,/p2/ construct with sed---it's not
          portable.  Handle broken AIX sed that strips \n from hold space
          when it shouldn't.  From Jun Hamano <[e-mail]>.

Tue Mar 02 00:08:39 1993  Jim Meyering  ([e-mail])

Mon Feb 22 13:02:27 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_QUOTE_HERE, AC_QUOTE_SED): Change the quote
    chars to { and } instead of nothing.  Then use {} (empty quotes) to
    separate the patsubst forms from the following dnl.  Otherwise the
    result of patsubst is pasted together with dnl and the result is
    seen as a single token.

    * acspecific.m4 (AC_MINUS_C_MINUS_O): Print msg saying what we are
    doing before we do it.

    * acgeneral.m4 (AC_PREFIX): Print out the choice made.

    * acgeneral.m4 (AC_DEFINE_QUOTE): Add dnl at end of line.

    * acspecific.m4 (AC_GETLOADAVG): Do changequote around listing of
    /dev/kmem and sed frobbing which needs to use [ and ].

    * autoheader.sh: Use brackets in tr range args.

    * acspecific.m4 (AC_SETVBUF_REVERSED): Make the test fail if
    setvbuf returns nonzero.

    * acspecific.m4 (AC_GETLOADAVG): If we need to install setgid,
    figure out what group owns /dev/kmem, and set KMEM_GROUP to that.

    * acspecific.m4 (AC_MINUS_C_MINUS_O): Test plain `cc' after testing
    $CC.  We want to make sure both compilers grok -c -o.

Thu Feb 18 18:05:14 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_QUOTE_{DQUOTE,SQUOTE,HERE,SED}): New macros.

Wed Feb 17 14:49:14 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_TIMEZONE): Fixed quoting in tzname check.
    changequote inside quotes lost.

Mon Feb  8 14:22:11 1993  Roland McGrath  ([e-mail])

    * acconfig.h (_ALL_SOURCE): Use #ifndef; AIX compiler way too dumb.

Sun Jan 31 16:39:46 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_TIMEZONE): Put newlines before `#include ...'
    in $defs value.

Thu Jan 28 18:06:53 1993  Roland McGrath  ([e-mail])

    * acconfig.h (_ALL_SOURCE): Use "!defined (_ALL_SOURCE) ||
    _ALL_SOURCE == 0" rather than "!_ALL_SOURCE", which bombs on the
    AIX compiler.

Mon Jan 25 12:09:43 1993  Roland McGrath  ([e-mail])

    * acconfig.h (HAVE_UNION_WAIT, SYS_SIGLIST_DECLARED): New #undef's.

Fri Jan 22 15:08:33 1993  Roland McGrath  ([e-mail])

    * acspecific.m4 (AC_GETLOADAVG): If /usr/local/lib/libgetloadavg.a
    exists, add -L/usr/local/lib to LDFLAGS.

Fri Jan 22 12:49:11 1993  David J. MacKenzie  ([e-mail])

    * acgeneral.m4 (AC_OUTPUT_HEADER): Only comment out the #undef NAME
    part of the line, to avoid causing errors from existing comments.

Thu Jan 21 14:50:20 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_HAVE_LIBRARY): Use $libname in "checking for"
    message, not $1, to avoid "checking for -l-lfoo".

    * acgeneral.m4 (AC_PREPARE): In compile defn, include $CFLAGS.

    * acgeneral.m4 (AC_OUTPUT): Broke AC_CONFIG_NAME writing out into:
    (AC_OUTPUT_HEADER): New macro broken out of AC_OUTPUT.
    Add to conftest.sed a new sed command to turn #undef's into comments.

    * acgeneral.m4 (AC_OUTPUT): Use new shell variable, $maxsedlines,
    for max number of lines to feed to one sed invocation.
    Lower this limit to 20; UTekV 3.2e can't cope with 40.

Tue Jan 19 13:21:02 1993  David J. MacKenzie  ([e-mail])

    * Version 1.3.

Fri Jan 15 16:28:18 1993  David J. MacKenzie  ([e-mail])

    * acgeneral.m4 (AC_FUNC_CHECK): Add missing #endif.

    * acgeneral.m4 (AC_OUTPUT): Use sed, not basename.
    From Francois Pinard.

Wed Jan 13 15:49:18 1993  Roland McGrath  ([e-mail])

    * acgeneral.m4 (AC_OUTPUT): Set exec_prefix to ${prefix}, not
    $(prefix); it now works in both makefiles and shell scripts.

Wed Jan 13 15:29:04 1993  David J. MacKenzie  ([e-mail])

    * autoheader.sh: If input is empty, don't print all of

    * acgeneral.m4 (AC_OUTPUT): Make config.status not complain with
    usage msg when given no args.

    * acgeneral.m4 (AC_HAVE_LIBRARY): Say "checking for -lfoo", not
    just "checking for foo".

    and $3.

    * acspecific.m4 (AC_GETLOADAVG): Check for getloadavg library, both
    a normally installed one, and one in /usr/local/lib.
    After figuring out params for getloadavg.c, figure out whether it
    defined LDAV_PRIVILEGED, and if so, set NEED_SETGID to true, and
    define GETLOADAVG_PRIVILEGED.
    * acconfig.h: Added GETLOADAVG_PRIVILEGED.
