17 Changes needed to automate the release process for 1.4.3:
19 * Makefile.in (dist): Make .tar.bz2 tarball too.
20 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
21 (cvs-news): Look 1 line further down for NEWS release number.
22 (cvs-dist): We don't use automake, so make dist is fine.

25 (fetch): Get latest gendocs files.
26 (web-manual): Rewritten to use gendoc for multiformat manuals.
27 * doc/gendocs.sh: Don't save an old version in m4 CVS!
28 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
29 preserving, but case insensitive, so generating html docs per node
30 clashes between Index.html, the node file, and index.html, the
31 top-level of the document tree...
32 (Index macro): ...so renamed to this. Changed all references.
34 2005-03-31 Gary V. Vaughan <gary@gnu.org> (tiny change)

94 2005-02-03 Gary V. Vaughan <gary@gnu.org>
96 Modernise the configury a little to prevent spurious errors from
97 Autoconf-2.59's autoreconf:

101 * acconfig.h: Removed.
102 * configure.in: Renamed to...

120 2005-02-03 Noah Misch <noah@cs.caltech.edu>
122 * src/output.c (mkstemp): Make non-static, and build regardless of

126 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
128 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
129 changes from your editor buffer first.

132 * src/m4.c: And include them as appropriate.
135 2004-09-09 Andreas Schwab <schwab@suse.de>

163 portability bug reported by Marion Hakanson in
164 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

285 Remove the sed filter after ansi2knr for debug.c. Use $O instead
286 of $U, put underline in extensions rather than in basenames. Use
287 implicit rules, now that regularity makes this possible.
288 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
289 of ansi2knr whenever it is needed.
290 * configure.in: Adjusted for correct STACKOVF substitution.
291 * src/debug.c (trace_format): When not __STDC__, use (...) as a

378 which is repeated in both goals.
380 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
384 * Makefile.in: Group all *clean-recursive goals in one, using sed

569 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
571 * m4.h: Include <sys/types.h>.
572 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
573 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
575 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
577 * builtin.c (dump_args): Declare len as size_t, not int.
579 * debug.c: Prototype the forward declaration of debug_set_file.
581 * builtin.c (m4_undivert): Replace div by file, for avoiding the
582 shadowing of this variable.
583 * output.c (insert_diversion): Idem.
585 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
586 (input_init): Duplicate default quote and comment strings.
587 (set_quotes): Free previous quote strings in all cases. Duplicate
588 even default quote strings.
589 (set_comment): Free previous comment strings in all cases.
590 Duplicate even default comment strings.
592 * configure.in: Updated for Autoconf 2.0.
593 * Makefile.in (distclean-local): Also delete config.cache.
595 * m4.c (usage): Reorganize the --help output by topic. Include a
596 description for debugging flags.
598 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
600 * configure.in: If sigaction is available and SA_ONSTACK defined,
601 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
602 defined, use sigvec. Else don't compile stackovf.c.
603 * stackovf.c (setup_stackovf_trap): Idem.
604 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
607 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
609 * m4.c (usage): Replace printf par fputs.
611 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
615 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
617 * configure.in: Check for sigaction and sigvec. Add a new delayed
618 check for RLIMIT_STACK, combine in the checking for getrlimit.
619 All those things are not universally available.
620 * stackovf.c: Split setting up the trap handler and catching
621 signals, for better taking care of various configure outcomes.
622 * examples/stackovf.sh: Correct a typo.
623 Reported by Eric Backus, Jim Avera and Jim Meyering.
625 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
627 * ansi2knr.c: New version sent by its author, Peter Deutsch.
629 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
631 * Makefile.in: Modify so parallel make will not try making
632 lib/libm4.a twice simultaneously.
633 Reported by Jim Meyering.
635 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
637 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
638 error message, for when no code possibility exists. Even if this
639 line is completely #ifdef'ed out, it brings a syntax error.
640 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
642 * Makefile.in (install): Have install depend on all too, for lib
643 to be remade as needed.
645 * examples/stackovf.sh: Try ksh, bsh and bash for shells
646 providing ulimit, instead of using only ksh.
647 Reported by Jim Avera and Joseph E. Sacco.
649 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
651 * Makefile.in (check): Have it depend on all instead of m4. In
652 this way, a change in lib will be detected and processed.
654 * builtin.c (numeric_arg): Use strtol and verify the conversion,
655 instead of using sscanf which stops as soon as there is a
656 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
657 and divert(1xyzzy) were all accepted without any warning or error
659 * m4.h: Declare strtol as long if not including stdlib.h.
660 * configure.in: Check for limits.h, and replace strtol if missing.
661 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
662 * lib/strtol.c: New file, from elsewhere.
663 Reported by Andreas Schwab.
665 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
667 * macro.c (expand_macro): Cast value to (boolean) prior to
668 assigning it to traced.
669 Reported by Tom McConnell.
671 * Makefile.in (m4): Always make all in lib first.
672 Reported by Jim Meyering.
674 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
676 * stackovf.c: Isolated OS-dependent sections; Improved portability,
677 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
678 handlers), and a default error message if the fault address is not
679 available (when neither siginfo.h nor BSD sigcontext are supported).
680 * configure.in: Changes for stackovf.h: Check for sigcontext,
681 sigaction, sigstack, and define rlim_t as int if necessary.
682 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
683 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
684 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
686 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
688 * configure.in: Use AC_SET_MAKE.
689 * Makefile.in: Use @SET_MAKE@.
690 Reported by Jim Meyering.
692 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
693 Reported by Ian Taylor.
695 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
697 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
698 because siginfo.h is unrelated to standard headers, and siginfo.h
699 is already checked for.
700 Reported by Joseph E. Sacco.
702 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
704 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
707 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
709 * builtin.c (substitute): Use \& to represent this part of the
710 string which was matched by the whole regexp, instead of
711 representing the whole string. Any usage of \0 issues a warning
712 and acts like \&, it will disappear in some subsequent release.
714 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
716 * m4.c: Complete prototype for forwarded declaration of usage.
718 * input.c (init_macro_token): Correct own reference in error
719 message. Previous name get_macro_func was referred to instead.
720 (next_char): Correct own reference in error message. Previous
721 name advance_input was referred to instead.
723 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
724 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
725 and_term, not_term, logical_not_term, cmp_term, shift_term,
726 add_term, mult_term, exp_term, unary_term, simple_term): Add
727 prototype to forwarded declarations. Declare parameter v1 as
728 eval_t * instead of int *. Same for local variable v2 in dyadic
729 functions. Same for result in exp_term.
730 * builtin.c (m4_eval): Declare value as eval_t instead of int.
731 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
732 unsigned_eval_t instead of unsigned int. Change casts accordingly.
733 (shipout_int): Cast first argument of ntoa to eval_t.
734 Reported by Thorsten Ohl.
736 * macro.c: Complete the prototypes of forwarded expand_macro and
738 Reported by Thorsten Ohl.
740 * m4.h: Define voidstar as void * or char * depending on __STDC__.
741 The Ultrix 3.1 compiler cannot do much with void pointers.
743 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
744 * m4.c (xfree): Replace void * by voidstar.
745 Reported by Tom McConnell.
747 * ansi2knr.1: New, from elsewhere.
748 * Makefile.in (DISTFILES): Distribute ansi2knr.1
750 * Makefile.in (stamp-h.in): Avoid running ./config.status if
751 stamp-h does not exist yet. This avoids running it a second time
752 just after the initial ./configure.
753 Reported by David MacKenzie and Tom McConnell.
755 * m4.h: Replace the enum debug_info declaration with a series of
756 #define's. The Ultrix 3.1 compiler would otherwise need casting
757 (int) to most references, when used in expressions.
758 Reported by Tom McConnell.
760 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
762 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
763 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
764 calls the compiler. Previously, FP_PROTOTYPES was only calling
765 the preprocessor; by not being subject to CFLAGS, this was
766 discouraging those flags asking for ANSI compilation.
767 * acconfig.h: Document HAVE_PROTOTYPES.
768 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
769 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
770 Reported by Eric Backus.
772 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
773 from the environment. Default CFLAGS to -g if not set.
774 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
775 * lib/Makefile.in: Have CFLAGS substituted from configure.
776 Reported by Eric Backus and Tom McConnell.
778 * configure.in: m4_undefine changeword before using AC_ENABLE.
780 * m4.h: Declare prototypes for error (for ANSI compilers only),
781 prefix_all_builtins and reference_error.
782 Reported by Tom McConnell.
784 * input.c (set_word_regexp): Do not try to initialize the array
785 test from a string, this does not work with non-ANSI compilers.
786 Reported by Eric Backus.
788 * Makefile.in (dist): Clean examples/ before saving it.
789 (distclean-local): Also remove stamp-h.
790 Reported by Eric Backus.
792 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
794 Reported by Tom McConnell.
796 * checks/Makefile.in (clean): Depends on mostlyclean.
797 (mostlyclean): New goal.
799 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
801 * Makefile.in (DISTFILES): Distribute install.sh.
802 * install.sh: New file, copied from elsewhere.
803 Reported by Assar Westerlund and Kaveh R. Ghazi.
805 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
807 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
808 * acconfig.h: Explain ENABLE_CHANGEWORD.
810 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
811 from code provided by Pete Chown]
812 * m4.h: Add original_text field to u_t variant of union u.
813 Declare TOKEN_DATA_FUNC macro.
814 * builtin.c: Declare changeword.
815 (m4_changeword): New function.
816 * input.c: Include "regex.h", define variables with word regexps.
817 (input_init): Initialize the word regexp.
818 (set_word_regexp): New.
819 (next_token): Declare local variables, use the previous code if
820 default_word_regexp is true. Else, match using a new code. Save
822 * macro.c (expand_token): Ship out original text if not a macro
824 Reported by Krste Asanovic and Pete Chown.
826 [These modifs all depend upon ENABLE_CHANGEWORD]
827 * m4.h: Declare external user_word_regexp.
828 * m4.c: Declare user_word_regexp, and initialize it from
829 --word-regexp or -W, or NULL if not specified.
830 * input.c: Use user_word_regexp if specified, instead of
833 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
836 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
837 * checks/Makefile.in: Empty the suffix list.
838 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
840 * m4.c: Declare nesting_limit and initialize it to 250.
841 Implement -LNUMBER or --nesting-limit=NUMBER to change its
843 * m4.h: Declare nesting_limit as external.
844 * macro.c (expand_macro): Stop execution whenever nesting limit
846 Reported by Bengt Mertensson.
848 * eval.c (evaluate): Diagnose excess characters in eval input.
849 Things like `eval(08)' used to return 0 with no diagnostic.
851 * m4.h: Capitalize first letter of all macro arguments in
854 * m4.c: Declare warning_status, initialize it to 0. Add new
855 option -E, or --fatal-warnings, which sets warning_status to
856 EXIT_FAILURE instead.
857 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
858 EXIT_FAILURE if not otherwise done by header files.
859 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
860 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
861 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
862 argument of all M4ERROR calls.
863 Reported by Noah Friedman.
865 * examples/incl-test.m4: Renamed from incl_test.m4.
866 * examples/include.m4: Include incl-test.m4 instead of
868 * examples/multiquotes.m4: Renamed from multi-quotes.m.
870 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
872 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
873 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
874 also tested it on a Sun Sparc workstation running SunOS 4.x.
876 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
877 49.format check, abusing a `union values' argument with sprintf
878 without selecting the proper field. Now, save the formatting type
879 first, delaying the fetch of the corresponding argument.
880 Reported by Joseph E. Sacco and Tom Quinn.
882 * format.c (format): Remove const from char *fmt declaration when
883 not HAVE_EFGCVT, because a NUL may be forced into it.
885 * m4.h: Declare atof() when not STDC_HEADERS.
886 Reported by Joseph E. Sacco.
888 * Regenerate configure using Autoconf 1.11, this corrects a
889 problem about an incorrect cpp seting on NeXT 3.1.
890 Reported by Alexander Lehmann.
892 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
894 * m4.h (_): Change argument from `x' to `Args'.
896 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
898 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
899 bringing more evil than good on a few systems.
900 Reported by Greg A. Woods.
902 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
904 * m4.h: Rename Args() to _().
905 * m4.h: Remove extern specifier from all function declarations.
907 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
909 * stackovf.c: New file implementing stack-overflow detection.
910 * configure.in: Check for getrlimit, sigaction. If all of
911 standard headers, getrlimit and sigaction, define USE_STACKOVF and
912 substitute ${U}stackovf.o for STACKOVF.
913 * acconfig.h: Declare USE_STACKOVF.
914 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
915 * m4.h: Declare setup_stackovf_trap().
916 * m4.c: Call setup_stackovf_trap().
917 * tests/stackovf_test.sh: New file.
919 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
921 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
923 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
925 Sun Jan 30 14:24:19 1994 (pinard at icule)
927 * m4.h: Remove definition of volatile, not used anymore.
928 Reported by Jim Meyering and Joseph E. Sacco.
930 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
931 of `if ... else /* nothing */' for if macros.
932 Reported by Jim Meyering.
934 * builtin.c (m4_regexp): Reorganize the code for avoiding a
935 warning from gcc about `repl' possibly used before defined.
936 Reported by Jim Meyering.
938 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
939 Reported by Jim Meyering.
941 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
943 * m4.h: Move the conditional definition of volatile after the
944 inclusion of system files, because they may define it first.
946 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
948 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
949 get around a problem with Alpha make seeing a syntax error, there.
950 Reported by Vern Paxson.
952 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
954 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
955 Reported by Richard Stallman.
957 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
959 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
960 instead of AC_HAVE_FUNCS.
961 Reported by Noah Friedman.
963 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
965 * m4.c: Initialize show_help and show_version to zero.
967 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
968 Use them in exit() and usage() calls.
970 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
972 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
973 syserr() macro. Delete errref, add reference_error and M4ERROR.
974 * m4.c: Replace errref, which was returning an input reference
975 string, with reference_error, which prints it on standard error.
976 * builtin.c, output.c: Use errno as second parameter to error,
977 instead of using syserr() with %s.
978 * *.c: Use M4ERROR instead of error: no more errref() with %s.
979 Doing so, the program name appears after the input reference
980 instead of before, which eases M-x next-error processing.
982 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
984 * checks/get-them: Escape braces with backslashes in patterns,
985 because HPUX-9.01 awk needs this.
986 Reported by Jim Meyering.
988 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
990 * builtin.c: Declare "FILE *popen ();".
992 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
993 macros, replace error_message_prefix() declaration by errref()'s.
994 Declare xrealloc, for use in errref().
995 * m4.c: Delete error_message_prefix() function, add errref().
996 * *.c: Use error() systematically in place of all error macros,
997 now that error() flushes stdout first. Make needed adjustments.
999 * m4.h: Remove const in sys_errlist[] declaration, it creates
1000 conflicts on SGI and Alpha.
1001 Reported by Kaveh R. Ghazi.
1003 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
1005 * m4.c: Include <getopt.h> instead of "getopt.h".
1007 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
1008 * acconfig.h: New, for documenting HAVE_EFGCVT.
1009 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
1010 use them wherever appropriate. Also use -I. for compilations.
1011 * lib/Makefile.in: Use -I.. for compilations.
1012 * *.c: Include <config.h> or "config.h".
1014 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
1015 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
1017 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
1019 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
1021 * input.c (input_init): Initialize quote and comment strings
1022 explicitely instead of calling set_quotes and set_comment: by
1023 doing so, we ensure we do not free uninitialized variables.
1025 * checks/check-them: Reverse arguments to both diff, so the
1026 expected is on the left and the obtained on the right.
1028 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
1029 macros. Delete declarations for m4error, warning, fatal and
1030 internal_error, add declaration for error_message_prefix.
1031 * m4.c: Delete m4error, warning, fatal and internal_error
1032 routines, add error_message_prefix routine.
1033 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
1034 warning with WARNING*, fatal with FATAL* and internal_error with
1036 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
1037 this is not needed anymore.
1039 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
1040 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
1041 and debug_message, add declaration for debug_message_prefix.
1042 * debug.c: Remove static specifier for FILE *debug declaration.
1043 Delete debug_print and debug_message routines, add
1044 debug_message_prefix routine.
1045 * builtin.c, debug.c: Replace debug_print routine calls with
1046 DEBUG_PRINT* macro calls.
1047 * input.c, path.c: Replace debug_message routine calls with
1048 DEBUG_MESSAGE* macro calls.
1050 * m4.h: Remove inclusion of <varargs.h>.
1051 * debug.c: Include <stdarg.h> or <varargs.h>.
1052 (trace_format): Use stdarg instead of varargs if __STDC__.
1054 * configure.in: Remove checks for vfprintf and _doprnt. These
1055 implementations use varargs tricks which are not portable enough.
1056 * lib/vfprintf.c: Deleted.
1057 * lib/_doprnt.c: Deleted.
1058 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
1059 Reported by Joel Sherrill.
1061 * path.c (add_include_directory): Use xstrdup.
1063 * builtin.c (find_builtin_by_name): Declare static.
1065 * *.[ch]: Add const to a few "char *" declarations.
1067 * configure.in: Remove commented tests for fileno() and fstat().
1068 * debug.c: Remove comments about HAVE_FILENO and HAVE_FSTAT.
1070 * debug.c (debug_flush_files): New.
1071 * m4.h: Declares it.

1073 Reported by Nicolas Pioch.
1075 Fri Nov 12 10:02:26 1993 Francois Pinard (pinard@icule)
1077 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
1078 Reported by Joel Sherrill.
1080 * builtin.c (prefix_all_builtins): Instead of the table size, use
1081 the null entry at end for stopping the loop. It was overwritten.
1082 Reported by Andreas Schwab and Jim Meyering.
1084 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
1085 Reported by Kaveh R. Ghazi.
1087 * macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).

1317 * Makefile.in (texclean, mostlyclean): New goals.
1319 * Makefile.in (clean): Remove clutter from ansi2knr.
1320 Reported by Pierre Gaumond.

1323 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
1325 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user

1336 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
1339 This is still a beta release for the future GNU m4 version 1.1.
1341 * lib/alloca.c: New, from elsewhere.
1342 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
1344 * m4.h: Do not define index/rindex if already defined. If
1345 FALSE/TRUE are already defined, do not redefine them, but merely
1346 define boolean typedef to int.
1348 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
1349 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
1350 because some C compilers do not like connectives with #ifdef.
1351 * m4.h: Define `volatile' only if __GNUC__, instead of once for
1352 __GNUC__ and once for __STDC__.
1353 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
1355 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
1356 Makefile dependencies. Without it, make keeps destroying and
1357 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
1359 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
1360 to diversion/DIVERSION, this was a spelling error.
1362 * m4.c: Declare version[], remove #include "version.h".
1363 * version.h: Deleted.
1364 * Makefile.in: Remove references to version.h.
1366 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
1367 production, by using a simpler and more robust algorithm. This
1368 solves the problem of synclines sometimes written in the middle of
1369 an output line. Delete sync_line() and output_lines variable.
1370 * m4.h: Remove sync_line prototype and output_lines declaration.
1371 * input.c (next_char), output.c (shipout_text): Remove references
1373 * input.c (push_file, pop_file): Merely put the value -1 in
1374 output_current_line instead of calling sync_line, for delaying a
1375 single `#line NUM FILE' before next output line. Do not test
1376 for sync_output, because this is unnecessary clutter.
1377 * output.c (make_divertion, insert_divertion): Idem.
1378 * input.c: Rename must_advance_line to start_of_input_line, for
1381 * debug.c (trace_header): Select a new debug line format, which
1382 better complies with GNU standards for formatting error messages.
1383 With option `-dfl', M-x next-error might be used on the output.
1384 * m4.c (vmesg): Adjust format of error output to GNU standards.
1385 * m4.texinfo: Adjust examples for `make check' to work.
1387 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
1388 case for enum debug_info constants, which were all lower case.
1390 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
1392 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
1393 collected patches. I tried a few times using newer regex.[ch], it
1394 mysteriously stopped aborting with this one. Insecure feeling...
1395 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
1397 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
1399 * m4.c: Change `--no-warnings' to `--silent'.
1400 Reported by David MacKenzie.
1402 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
1403 leave it off for now. See comment in m4.c for justification.
1404 Reported by David MacKenzie.
1406 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
1407 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
1409 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
1411 * Makefile.in: Ensure recursive cleaning is done before local
1412 cleaning for all clean goals.
1414 * builtin.c (ntoa): Ensure the value is always interpreted as a
1415 signed quantity, whatever the radix is.
1417 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
1419 * builtin.c, format.c, input.c: Split long lines.
1420 * m4.c: Use typedef macro_definition instead of struct
1422 * symtab.c: Use typedef symbol instead of struct symbol.
1424 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
1426 * *.[ch]: Remove all trailing whitespace, in code and comments.
1428 * configure.in: Find some awk.
1429 * Makefile.in: Add $(AWK) to MDEFINES.
1430 * checks/Makefile.in: Transmit $(AWK) to get_them.
1431 * checks/get_them: Use $AWK instead of gawk. Add a close in the
1432 awk script when switching files, because without this, mawk runs
1433 out of file descriptors.
1435 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
1437 * Makefile.in (realclean): Delete m4.info*.
1438 Reported by Jim Meyering.
1440 * Makefile.in: Adjust and link with checks/Makefile.
1441 * checks/Makefile.in: New.
1442 * configure.in: Output checks/Makefile.
1444 * checks/get_them: Have the dnl header of each test more
1445 recognizable by next-error, also use a better message.
1447 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
1449 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
1450 And use that only if __GNUC__ since we're using it's GCC-specific
1451 semantics that tell the compiler the associated function doesn't
1454 * builtin.c (substitute): Don't use character as an array index.
1455 (dumpdef_cmp): Make formal arguments `const void *' to avoid
1456 warnings with gcc -W -Wall on systems with qsort prototype.
1457 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
1460 * eval.c (most functions): Add parentheses to assignments used
1461 as truth values go avoid warnings from gcc -Wall.
1463 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
1464 any functions that don't need external scope.
1466 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
1467 (many functions and arrays): Declare `const'.
1469 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
1471 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
1472 removing the declaration from m4.h. Also rename false to FALSE
1475 * lib/Makefile.in (Makefile): New goal.
1477 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
1478 so heavily loaded. It gets more easily overridable, calling make.
1479 Reported by Jim Meyering.
1481 * Makefile.in (dist): Get .fname from the current directory name,
1482 instead of from version.h. I need updating many files manually,
1483 when the version changes, version.h is just one of them.
1485 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
1487 * m4.h: Remove the tag `boolean' on the enum introducing typedef
1488 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
1489 Reported by Tom McConnell.
1491 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
1493 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
1494 39.cleardiv, which were describing missing or spurious newlines.
1495 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
1496 do not depend on machine word size, `/bin/false' implementation,
1497 or `wc' output format. `make check' is more dependable, now.
1499 * checks/check_them: Summarize the failed tests by listing their
1500 name, at end. If none, issue `All checks successful'. Output
1501 `Checking' instead of `Input file:'.
1503 * checks/get_them, checks/check_them: Reindented.
1505 * Makefile.in (dist): chmod a+r before making the tar file.
1507 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
1509 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
1511 * input.c (next_token): Reinitialize token_buttom just after using
1512 it as a watermark with obstack_free. Or else, a future token, big
1513 enough for triggering reallocation of the obstack chunk, could
1514 void the initialized value of token_buttom, later causing panic in
1515 obstack_free. Rename token_buttom to token_bottom everywhere.
1517 * m4.h: Before declaring errno, first include <errno.h> and
1518 ensure that it does not define errno.
1519 Reported by Richard Stallman.
1521 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
1523 * builtin.c: Define and use DECLARE macro for builtins.
1525 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
1526 argument, this is a common idiom for introducing long comments.
1528 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
1529 arguments. The last argument was silently ignored.
1531 * m4.c (cmd_error): Add a missing semicolon before va_end().
1533 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
1535 * Makefile.in: Now handle protoized sources. Define and use U.
1536 Compile and use ansi2knr with old compilers. Update DISTFILES.
1537 Add `aclocal.m4' to `configure' dependencies.
1538 * ansi2knr.c: New, from Ghostscript distribution.
1539 * configure.in: Define U through FP_PROTOTYPES for old compilers.
1540 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
1541 * aclocal.m4: New, provide FP_PROTOTYPES.
1542 * m4.h: Conditionnaly protoized through Args, save for varags.
1543 * builtin.c: Protoized. Then:
1544 Include <sys/types.h> if size_t is not defined, before "regex.h".

1546 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
1547 (m4_regexp): Add const to `msg' declaration.
1548 (m4_patsubst): Add const to `msg' declaration.
1549 * debug.c: Protoized, save for varargs.
1550 * eval.c: Protoized.
1551 * format.c: Protoized.
1552 * input.c: Protoized.
1553 * m4.c: Protoized, save for varargs. Then:
1554 (xfree): Accept void * instead of char *.
1555 (xmalloc): Return void * instead of char *.
1556 (xrealloc): Accept and return void * instead of char *.
1557 * macro.c: Protoized.
1558 * output.c: Protoized.
1559 * path.c: Protoized. Then cast some (char *) over xmalloc's.
1560 * symtab.c: Protoized.
1562 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
1564 * m4.texinfo: Remove directory from diagnostics in 30.include,
1565 51.eval, 56.errprint and 57.m4exit tests.
1567 * m4.h: Remove declarations for int or void system functions, they
1568 cause more conflicting trouble than they make good.
1570 * configure.in: Avoid configuration header file. Add some tests.
1571 * m4.h: Remove #include "config.h".
1572 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
1573 Then, rewritten for better compliance with GNU standards.
1575 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
1577 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
1578 because of a misplaced #endif.
1580 * Many *.[hc] files: Correct intra-line spacing here and there,
1581 according to GNU indent 1.6 advice.
1583 * configure.in: New, using Autoconf 1.2.

1590 Reported by Jason Merrill.
1592 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
1593 etc/nextvers.sh. Release numbers will be edited `by hand'.
1594 * version.h: De-automatize, force value in.
1596 * m4.c: Changes in order to use a newer getopt.h.
1597 Reported by David MacKenzie.
1599 * checks/: New name for examples/.
1600 * checks/get_them: New location for etc/get_examples.
