    Reported by Karl Berry <[e-mail]>.

Fri Jan 15 16:07:00 1993  Francois Pinard  (pinard@icule)

    * lib/vfprintf.c: Stolen from Oleo distribution and adapted.  The

    * Makefile.in: Add DEFS to MDEFINES.
    * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).

    * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
    macro.c, output.c, path.c, symtab.c: Change Copyright from
    1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.

    * examples/divert.m4: Deleted, this bug has been corrected.

Sat Dec 19 08:21:34 1992  Francois Pinard  (pinard at icule)

    * Version 1.0.3 released to <prep.ai.mit.edu>.  This is still a
    beta release for the future GNU m4 version 1.1.

    * lib/alloca.c: New, from elsewhere.
    * lib/Makefile.in: Distribute it.  Define and use $(ALLOCA).

    * m4.h: Do not define index/rindex if already defined.  If
    FALSE/TRUE are already defined, do not redefine them, but merely
    define boolean typedef to int.

    * Makefile.in: Use $(DEFS) while compiling ansi2knr.
    * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
    because some C compilers do not like connectives with #ifdef.
    * m4.h: Define `volatile' only if __GNUC__, instead of once for
    __GNUC__ and once for __STDC__.
    * lib/regex.h: Leave const alone, AC_CONST will take care of it.

    * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
    Makefile dependencies.  Without it, make keeps destroying and
    remaking $(CHECKS) in a loop (why?).  Distribute .all_stamp.

    * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
    to diversion/DIVERSION, this was a spelling error.

    * m4.c: Declare version[], remove #include "version.h".
    * version.h: Deleted.
    * Makefile.in: Remove references to version.h.

    * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
    production, by using a simpler and more robust algorithm.  This
    solves the problem of synclines sometimes written in the middle of
    an output line.  Delete sync_line() and output_lines variable.
    * m4.h: Remove sync_line prototype and output_lines declaration.
    * input.c (next_char), output.c (shipout_text): Remove references
    to output_lines.
    * input.c (push_file, pop_file): Merely put the value -1 in
    output_current_line instead of calling sync_line, for delaying a
    single `#line NUM FILE' before next output line.  Do not test
    for sync_output, because this is unnecessary clutter.
    * output.c (make_divertion, insert_divertion): Idem.
    * input.c: Rename must_advance_line to start_of_input_line, for
    consistency.

    * debug.c (trace_header): Select a new debug line format, which
    better complies with GNU standards for formatting error messages.
    With option `-dfl', M-x next-error might be used on the output.
    * m4.c (vmesg): Adjust format of error output to GNU standards.
    * m4.texinfo: Adjust examples for `make check' to work.

    * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
    case for enum debug_info constants, which were all lower case.

    * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
    re_search_2.
    * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
    collected patches.  I tried a few times using newer regex.[ch], it
    mysteriously stopped aborting with this one.  Insecure feeling...
    * lib/Makefile.in: Distribute regex.[ch].old, just in case!

Fri Dec 18 11:08:03 1992  Francois Pinard  (pinard at icule)

    * m4.c: Change `--no-warnings' to `--silent'.
    Reported by David MacKenzie <[e-mail]>.

    * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
    leave it off for now.  See comment in m4.c for justification.
    Reported by David MacKenzie <[e-mail]>.

    * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
    * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.

    * Makefile.in: Add a new `info' goal.  Use macro MAKEINFO.

    * Makefile.in: Ensure recursive cleaning is done before local
    cleaning for all clean goals.

    * builtin.c (ntoa): Ensure the value is always interpreted as a
    signed quantity, whatever the radix is.

Wed Nov 18 07:57:19 1992  Jim Meyering  (meyering@idefix)

    * builtin.c, format.c, input.c: Split long lines.
    * m4.c: Use typedef macro_definition instead of struct
    macro_definition.
    * symtab.c: Use typedef symbol instead of struct symbol.

Tue Nov 17 01:58:40 1992  Francois Pinard  (pinard at icule)

    * all: Remove all trailing whitespace, in code and comments.

    * configure.in: Find some awk.
    * Makefile.in: Add $(AWK) to MDEFINES.
    * checks/Makefile.in: Transmit $(AWK) to get_them.
    * checks/get_them: Use $AWK instead of gawk.  Add a close in the
    awk script when switching files, because without this, mawk runs
    out of file descriptors.

Mon Nov 16 20:42:56 1992  Francois Pinard  (pinard at icule)

    * Makefile.in (realclean): Delete m4.info*.
    Reported by Jim Meyering <[e-mail]>.

    * Makefile.in: Adjust and link with checks/Makefile.
    * checks/Makefile.in: New.
    * configure.in: Output checks/Makefile.

    * checks/get_them: Have the dnl header of each test more
    recognizable by next-error, also use a better message.

Mon Nov 16 07:48:52 1992  Jim Meyering  (meyering@idefix)

        * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
        And use that only if __GNUC__ since we're using it's GCC-specific
        semantics that tell the compiler the associated function doesn't
        return.

        * builtin.c (substitute): Don't use character as an array index.
        (dumpdef_cmp): Make formal arguments `const void *' to avoid
        warnings with gcc -W -Wall on systems with qsort prototype.
        (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
        from gcc -W -Wall.

        * eval.c (most functions): Add parentheses to assignments used
        as truth values go avoid warnings from gcc -Wall.

    * input.c, m4.c, output.c, path.c, symtab.c: Declare static
    any functions that don't need external scope.

    * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
    (many functions and arrays): Declare `const'.

Sun Nov 15 09:42:09 1992  Francois Pinard  (pinard at icule)

    * all: Rename nil to NULL, using the declaration from <stdio.h>,
    removing the declaration from m4.h.  Also rename false to FALSE
    and true to TRUE.

    * lib/Makefile.in (Makefile): New goal.

    * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
    so heavily loaded.  It gets more easily overridable, calling make.
    Reported by Jim Meyering <[e-mail]>.

    * Makefile.in (dist): Get .fname from the current directory name,
    instead of from version.h.  I need updating many files manually,
    when the version changes, version.h is just one of them.

Sat Nov 14 11:01:20 1992  Francois Pinard  (pinard at icule)

    * m4.h: Remove the tag `boolean' on the enum introducing typedef
    `boolean'.  This tag conflicts with <sys/types.h> on SVR4.
    Reported by Tom McConnell <[e-mail]>.

Fri Nov 13 00:12:50 1992  Francois Pinard  (pinard at icule)

    * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
    39.cleardiv, which were describing missing or spurious newlines.
    Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
    do not depend on machine word size, `/bin/false' implementation,
    or `wc' output format.  `make check' is more dependable, now.

    * checks/check_them: Summarize the failed tests by listing their
    name, at end.  If none, issue `All checks successful'.  Output
    `Checking' instead of `Input file:'.

    * checks/get_them, checks/check_them: Reindented.

    * Makefile.in (dist): chmod a+r before making the tar file.

Thu Nov 12 14:42:57 1992  Francois Pinard  (pinard at icule)

    * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.

    * input.c (next_token): Reinitialize token_buttom just after using
    it as a watermark with obstack_free.  Or else, a future token, big
    enough for triggering reallocation of the obstack chunk, could
    void the initialized value of token_buttom, later causing panic in
    obstack_free.  Rename token_buttom to token_bottom everywhere.

    * m4.h: Before declaring errno, first include <errno.h> and
    ensure that it does not define errno.
    Reported by Richard Stallman <[e-mail]>.

Wed Nov 11 17:40:35 1992  Francois Pinard  (pinard at icule)

    * builtin.c: Define and use DECLARE macro for builtins.

    * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
    argument, this is a common idiom for introducing long comments.

    * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
    arguments.  The last argument was silently ignored.

    * m4.c (cmd_error): Add a missing semicolon before va_end().

Tue Nov 10 08:57:05 1992  Francois Pinard  (pinard at icule)

    * Makefile.in: Now handle protoized sources.  Define and use U.
    Compile and use ansi2knr with old compilers.  Update DISTFILES.
    Add `aclocal.m4' to `configure' dependencies.
    * ansi2knr.c: New, from Ghostscript distribution.
    * configure.in: Define U through FP_PROTOTYPES for old compilers.
    Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
    * aclocal.m4: New, provide FP_PROTOTYPES.
    * m4.h: Conditionnaly protoized through Args, save for varags.
    * builtin.c: Protoized.  Then:
    Include <sys/types.h> if size_t is not defined, before "regex.h".
    (m4_ifelse): Fetch built-in name properly for diagnostic.
    (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
    (m4_regexp): Add const to `msg' declaration.

    * eval.c: Protoized.
    * format.c: Protoized.
    * input.c: Protoized.
    * m4.c: Protoized, save for varargs.  Then:
    (xfree): Accept void * instead of char *.
    (xmalloc): Return void * instead of char *.
    (xrealloc): Accept and return void * instead of char *.
    * macro.c: Protoized.
    * output.c: Protoized.
    * path.c: Protoized.  Then cast some (char *) over xmalloc's.
    * symtab.c: Protoized.

Fri Nov  6 02:05:21 1992  Francois Pinard  (pinard at icule)

    * m4.texinfo: Remove directory from diagnostics in 30.include,
    51.eval, 56.errprint and 57.m4exit tests.

    * m4.h: Remove declarations for int or void system functions, they
    cause more conflicting trouble than they make good.

    * configure.in: Avoid configuration header file.  Add some tests.
    * m4.h: Remove #include "config.h".
    * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
    Then, rewritten for better compliance with GNU standards.

Thu Nov  5 12:37:13 1992  Francois Pinard  (pinard at icule)

    * format.c (format): Avoid syntax error if not HAVE_EFGCVT,

    * Makefile.in (check): Add m4 as dependency.

    * m4.c: Accept --no-warnings instead of --no_warnings, and
    --no-gnu-extensions instead of --no_gnu_extensions.  Make the

    * Version 1.0.  Many thanks to those, who provided me with bug
    reports and feedback.

    * Uses GNU configure, taken from the gdb distribution.

    * Uses GNU getopt(), with long option names.

    * The -Q/+quiet option is added, which suppresses warnings about
    missing or superflous arguments to built-in macros.

    * Added default options via the M4OPTS environment variable.

    * The built-in format can now be configured to use sprintf as
    the formatting engine, for systems without [efg]cvt(3).

    * GNU library code is moved to the ./lib subdirectory; other
    utility files are now in ./etc.

    * Several minor bugs have been fixed.

    * Fixed various bugs.  Version 0.99, manual 0.09.  Many thanks to
    Francois Pinard <[e-mail]> and Roland H. Pesch
    <[e-mail]> for providing me with reports.

    * The builtins incr and decr are now implemented without use of
    eval.

    * The builtin indir is added, to allow for indirect macro calls
    (allows use of "illegal" macro names).

    * The debugging and tracing facilities has been enhanced
    considerably.  See the manual for details.

    * The -tMACRO option is added, marks MACRO for tracing as soon
    as it is defined.

    * Builtins are traced after renaming iff they were before.

    * Named files can now be undiverted.

    * The -Nnum option can be used to increase the number of
    divertions available.

    * Calling changecom without arguments now disables all comment
    handling.

    * The function m4_patsubst() is now consistently declared
    static.

    * A bug in dnl is fixed.

    * A bug in the multi-character quoting code is fixed.

    * Several typos in the manual has been corrected.  More probably
    persist.

    * The m4.info file is now installed along with the program.

    * Updated and enhanced version.  Version 0.75, manual 0.07.

    * Implemented search path for include files (-I option and
    M4PATH envronment variable).

    * Implemented builtin "format" for printf-like formatting.

    * Implemented builtin "regexp" for searching for regular
    expressions.

    * Implemented builtin "patsubst" for substitution with regular
    expressions.

    * Implemented builtin "esyscmd", which expands to a shell
    commands output.

    * Implemented "__file__" and "__line__" for use in error
    messages.

    * Implemented character ranges in "translit".

    * Implemented control over debugging output.

    * Changed "shift", "$@" and "$*" to not insert spaces afters
    commas.

    * Added program name to error messages.

    * Fixed two missing null bytes bugs.
