    * Version 1.6.

Fri May 21 22:57:53 1993  Jim Meyering  ([e-mail])

    * pr.c (cols_ready_to_print): New function.  It replaces a global
    variable by the same name and computes on the fly the value that
    was supposed to be maintained through that variable.  This should
    put to rest the `pr -2a' bug.
    (main): Don't let getopt_long reorder arguments so we can
    distinguish between `pr -1 -2' and `pr -12'.  Rework handling of
    -n and +n options.

    * fold.c: Declare xmalloc.

Wed May 19 19:12:18 1993  Karl Berry  ([e-mail])

    * sort.c (main): fflush before exit, so a closed stdout doesn't lose.

Tue May 18 23:49:26 1993  Jim Meyering ([e-mail])

    * mkinstalldirs: New file.
    * Makefile.in (installdirs): Use it to create installation directories.

Fri May 14 23:45:52 1993  Jim Meyering  ([e-mail])

    * all source: With --version, print version and exit immediately.

Thu May 13 01:03:16 1993  Jim Meyering  ([e-mail])

    * Makefile.in (installdirs): New rules for creating installation
    directories. (install): depend on it.

    * tail.c (main): Remove --compatible since `+1f' may be used
    to get the BSD `-0f' behavior portably.

    * fold.c (main): Turn -N arguments, where N is a digit, into -wN.
    From Ian Lance Taylor ([e-mail]).

Mon May 10 22:33:44 1993  Jim Meyering  ([e-mail])

    * tail.c (main): New option -C, --compatible to make `tail -0f'
    work like `tail +1f' for compatibility with BSD tail.

Thu May  6 23:28:56 1993  Jim Meyering  ([e-mail])

    * pr.c (print_page): Decrement cols_ready_to_print even when
    lines_to_print == 0.  The command `echo |pr -2ta' *still* didn't
    terminate.  Add parentheses for clarity.

Mon May  3 23:57:47 1993  Jim Meyering  ([e-mail])

    * Version 1.5.

    * od.c (main): Remove set-but-not-used variable, `usage_error'.

    * split.c (main): Call usage with an argument.

Sun May  2 16:05:04 1993  Jim Meyering  ([e-mail])

    * configure.in: Reverse if-else branches in AC_TEST_PROGRAM test
    for 8-bit clean memcmp.

    * cat.c (usage, main): Remove unused argument.

    * csplit.c (remove_line): Remove set-but-not-used variable, `line_got.'
    (check_for_offset): Remove unused argument `argnum.'

    * configure.in: Add AC_SIZE_T.

Sat May  1 09:03:19 1993  Jim Meyering  ([e-mail])

    * uniq.c (main): Interpret non-option arguments with a leading `+'
    only if we haven't seen `--'.

    * tr.c (main): Change variable name to avoid shadowed dcl.
    * wc.c (write_counts): Ditto.

    * sum.1: Make documentation agree with the code.

    * od.c: Depend only on HAVE_LONG_DOUBLE for long double support.

Fri Apr 30 20:16:03 1993  Jim Meyering  ([e-mail])

    * configure.in [AC_HAVE_HEADERS]: Add limits.h.

    * configure.in [CFLAGS, LDFLAGS]: Assign reasonable defaults.

    * od.c (parse_old_offset): Don't use prototype in function
    definition.  Remove unnecessary conjunct from test for hexadecimal
    prefix.

    * od.c: Depend on __GNUC__ || HAVE_LONG_DOUBLE rather than __STDC__
    for long double support;  there are compilers (Stardent Vistra svr4)
    without long double but still define __STDC__.

Thu Apr 29 02:01:27 1993  Jim Meyering  ([e-mail])

    * src/*.c and man/*.c except for sort: Add --help and --version
    options.

    * pr.c: Convert to use getopt_long.

    * lib/memcmp.c: Use version from glibc.
    [WORDS_BIGENDIAN]: Test this instead of the using glibc's
    __BYTE_ORDER macro.
    * configure.in: Use AC_WORDS_BIGENDIAN to set it.

    * od.c (parse_old_offset): Allow `0X' as well as `0x' prefix to
    indicate hex.

    * Makefile.in (dist): Depend on Makefile so that changes to
    Makefile.in (like adding new files to DISTRIB) are reflected
    in the new distribution.

Fri Apr 23 21:53:47 1993  Jim Meyering  ([e-mail])

    * {lib,src}/Makefile.in [.c.o]: Make CPPFLAGS and CFLAGS follow
    other options so users can use them to override DEFS.
    * src/Makefile.in [.c.o]: Add -I$(srcdir) for version.h.

    * Makefile.in [CFLAGS, LDFLAGS]: Don't set to -g explicitely;
    configure's AC_SUBST will set these.

    * Makefile.in [Makefile]: Add dependencies and a rule to remake it.
    [targets that cd then run make in subdirectories]: Don't depend
    on `cd ..';  use a subshell instead.

    * Makefile.in [info, install-info, dvi, check, installcheck]:
    New targets but no rules; comply with standards.

    * configure.in [CFLAGS]: Default to -g -O if CC is gcc and the user
    hasn't specified CFLAGS.
    [LDFLAGS]: Substitute into Makefile.

Tue Mar 30 21:36:11 1993  Jim Meyering  ([e-mail])

    * od.c: New option --compatible, -C.

Sun Mar 28 16:59:31 1993  Mike Haertel  ([e-mail])

    * configure.in: Add check for working memcmp; use GNU's if
    the system's doesn't grok the 8th bit.
    * memcmp.c: Fix it so it groks the 8th bit.
    TODO: We really need to provide a fast memcmp, since most
    machines will have a broken memcmp.  Probably should get
    the one from glibc.
    * sort.c (mergefps): Maintain keybeg and keylim when copying
    the current line to `saved'.
    (numcompare): Skip white space here since -n no longer implies -b.
    (getmonth): Skip white space here since -M no longer implies -b.
    (compare): Completely overhauled to make the 8th bit work right,
    also to properly handle the global reverse option.
    (set_ordering): -n no longer implies -b, according to Posix.
    For consistency, -M also no longer implies -b.
    (main): Correct treatment of -r and global keys.
    (findlines): Clear keybeg and keylim if no keys are used.
    (sort): Avoid overwriting tempfiles[] array bounds.

Sun Mar 21 22:29:29 1993  Jim Meyering  ([e-mail])

    * pr.c (close_file): Reverse May 13, '92 change, but add the condition
    that cols_ready_to_print not be decremented when printing across.
    The command `echo |pr -2ta' didn't terminate.
    (print_page): Rewrite conditional (that had side effects in second
    conjunct) using nested if statements to make it clear that we do
    indeed want those semantics.

Tue Jan 19 13:35:24 1993  David J. MacKenzie  ([e-mail])

    * Version 1.4.

    * system.h: Try BBSIZE if BSIZE isn't defined.

    From Ian Lance Taylor.

Wed Dec  2 12:28:10 1992  Jim Meyering  ([e-mail])

    * sum.c (sysv_sum_file): Use %lu instead of %u to print a

    (append_normal_char, append_range, append_char_class,
    append_repeated_char, append_equiv_class, spec_init):

    * tr.c: Rename --sysv-string2-truncate to --truncate-string1.

Fri Jan 17 16:29:05 1992  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

    (check_section): Use memcmp instead of strncmp.
    (proc_text): Print line_buf with fwrite instead of printf.

    * nl.c (main): Usage message if too many args given.  Check
    for error in closing input file.  Lengths of section delimiter
    strings were 1 too large.  Take separator_str into account in
    length of print_no_line_fmt.
    (build_print_fmt): Allocate space for print_fmt, in case
    separator_str is long.

    * (print_page): Fixed bug that had pr -3 -a printing two too few
    trailer lines per page.
    * (main): Added restriction that -a and -m are incompatible.
    Although the POSIX spec doesn't explicitly say they shouldn't
    be used together, it says -a modifies the -column option and
    that -column shouldn't be used with -m.

Thu Jan  2 15:23:59 1992  David J. MacKenzie  (djm at albert.gnu.ai.mit.edu)

    to step through the input by two.
    * tr.c (set_initialize): Write a comment describing the function.
    * tr.c: Eliminated the variable `portability_warnings' and replaced
    references to it by references to `!posix_pedantic'.  One of the
    uses of portability_warnings had been wrong.

Tue Dec  3 14:03:35 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

    * tr.c: New program.

Sun Dec  1 15:07:35 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

    * linebuffer.[ch] (freebuffer): New function (used by cron).

Thu Oct 17 22:30:22 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

    * pr.c: The following 3 bugs appeared (at least) when printing
    a  single file with the options `-3 -f'.
    * (print_white_space): Single spaces were being replaced
    with tabs.

    at the beginning because spaces_not_printed wasn't being reset
    to 0.
    * (read_line): The single space between a truncated column
    on its left and the column on its right was omitted.  Fixed
    so that previous value of input_position is restored before

    unchanged (for POSIX).

Sat Aug 17 01:49:41 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)

Tue Mar 20 14:28:25 1990  David J. MacKenzie  (djm at pogo.ai.mit.edu)
