2296 of $U, put underline in extensions rather than in basenames. Use
2297 implicit rules, now that regularity makes this possible.
2298 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation

2646 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2647 error message, for when no code possibility exists. Even if this
2648 line is completely #ifdef'ed out, it brings a syntax error.
2649 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2651 * Makefile.in (install): Have install depend on all too, for lib
2652 to be remade as needed.
2654 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2655 providing ulimit, instead of using only ksh.
2656 Reported by Jim Avera and Joseph E. Sacco.
2658 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2660 * Makefile.in (check): Have it depend on all instead of m4. In
2661 this way, a change in lib will be detected and processed.
2663 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2664 instead of using sscanf which stops as soon as there is a
2665 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2666 and divert(1xyzzy) were all accepted without any warning or error
2668 * m4.h: Declare strtol as long if not including stdlib.h.
2669 * configure.in: Check for limits.h, and replace strtol if missing.
2670 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2671 * lib/strtol.c: New file, from elsewhere.
2672 Reported by Andreas Schwab.
2674 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2676 * macro.c (expand_macro): Cast value to (boolean) prior to
2677 assigning it to traced.
2678 Reported by Tom McConnell.
2680 * Makefile.in (m4): Always make all in lib first.
2681 Reported by Jim Meyering.
2683 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2685 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2686 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2687 handlers), and a default error message if the fault address is not
2688 available (when neither siginfo.h nor BSD sigcontext are supported).
2689 * configure.in: Changes for stackovf.h: Check for sigcontext,
2690 sigaction, sigstack, and define rlim_t as int if necessary.
2691 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2692 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2693 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2695 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2697 * configure.in: Use AC_SET_MAKE.
2698 * Makefile.in: Use @SET_MAKE@.
2699 Reported by Jim Meyering.
2701 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2702 Reported by Ian Taylor.
2704 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2706 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2707 because siginfo.h is unrelated to standard headers, and siginfo.h
2708 is already checked for.
2709 Reported by Joseph E. Sacco.
2711 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2713 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2716 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2718 * builtin.c (substitute): Use \& to represent this part of the
2719 string which was matched by the whole regexp, instead of
2720 representing the whole string. Any usage of \0 issues a warning
2721 and acts like \&, it will disappear in some subsequent release.
2723 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2725 * m4.c: Complete prototype for forwarded declaration of usage.
2727 * input.c (init_macro_token): Correct own reference in error
2728 message. Previous name get_macro_func was referred to instead.
2729 (next_char): Correct own reference in error message. Previous
2730 name advance_input was referred to instead.
2732 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2733 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2734 and_term, not_term, logical_not_term, cmp_term, shift_term,
2735 add_term, mult_term, exp_term, unary_term, simple_term): Add
2736 prototype to forwarded declarations. Declare parameter v1 as
2737 eval_t * instead of int *. Same for local variable v2 in dyadic
2738 functions. Same for result in exp_term.
2739 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2740 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2741 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2742 (shipout_int): Cast first argument of ntoa to eval_t.
2743 Reported by Thorsten Ohl.
2745 * macro.c: Complete the prototypes of forwarded expand_macro and
2747 Reported by Thorsten Ohl.
2749 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2750 The Ultrix 3.1 compiler cannot do much with void pointers.
2752 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2753 * m4.c (xfree): Replace void * by voidstar.
2754 Reported by Tom McConnell.
2756 * ansi2knr.1: New, from elsewhere.
2757 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2759 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2760 stamp-h does not exist yet. This avoids running it a second time
2761 just after the initial ./configure.
2762 Reported by David MacKenzie and Tom McConnell.
2764 * m4.h: Replace the enum debug_info declaration with a series of
2765 #define's. The Ultrix 3.1 compiler would otherwise need casting
2766 (int) to most references, when used in expressions.
2767 Reported by Tom McConnell.
2769 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2771 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2772 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2773 calls the compiler. Previously, FP_PROTOTYPES was only calling
2774 the preprocessor; by not being subject to CFLAGS, this was
2775 discouraging those flags asking for ANSI compilation.
2776 * acconfig.h: Document HAVE_PROTOTYPES.
2777 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2778 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2779 Reported by Eric Backus.
2781 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2782 from the environment. Default CFLAGS to -g if not set.
2783 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2784 * lib/Makefile.in: Have CFLAGS substituted from configure.
2785 Reported by Eric Backus and Tom McConnell.
2787 * configure.in: m4_undefine changeword before using AC_ENABLE.
2789 * m4.h: Declare prototypes for error (for ANSI compilers only),
2790 prefix_all_builtins and reference_error.
2791 Reported by Tom McConnell.
2793 * input.c (set_word_regexp): Do not try to initialize the array
2794 test from a string, this does not work with non-ANSI compilers.
2795 Reported by Eric Backus.
2797 * Makefile.in (dist): Clean examples/ before saving it.
2798 (distclean-local): Also remove stamp-h.
2799 Reported by Eric Backus.
2801 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2803 Reported by Tom McConnell.
2805 * checks/Makefile.in (clean): Depends on mostlyclean.
2806 (mostlyclean): New goal.
2808 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2810 * Makefile.in (DISTFILES): Distribute install.sh.
2811 * install.sh: New file, copied from elsewhere.
2812 Reported by Assar Westerlund and Kaveh R. Ghazi.
2814 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2816 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2817 * acconfig.h: Explain ENABLE_CHANGEWORD.
2819 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2820 from code provided by Pete Chown]
2821 * m4.h: Add original_text field to u_t variant of union u.
2822 Declare TOKEN_DATA_FUNC macro.
2823 * builtin.c: Declare changeword.
2824 (m4_changeword): New function.
2825 * input.c: Include "regex.h", define variables with word regexps.
2826 (input_init): Initialize the word regexp.
2827 (set_word_regexp): New.
2828 (next_token): Declare local variables, use the previous code if
2829 default_word_regexp is true. Else, match using a new code. Save
2831 * macro.c (expand_token): Ship out original text if not a macro
2833 Reported by Krste Asanovic and Pete Chown.
2835 [These modifs all depend upon ENABLE_CHANGEWORD]
2836 * m4.h: Declare external user_word_regexp.
2837 * m4.c: Declare user_word_regexp, and initialize it from
2838 --word-regexp or -W, or NULL if not specified.
2839 * input.c: Use user_word_regexp if specified, instead of
2840 DEFAULT_WORD_REGEXP.
2842 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2845 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2846 * checks/Makefile.in: Empty the suffix list.
2847 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2849 * m4.c: Declare nesting_limit and initialize it to 250.
2850 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2852 * m4.h: Declare nesting_limit as external.
2853 * macro.c (expand_macro): Stop execution whenever nesting limit
2855 Reported by Bengt Mertensson.
2857 * eval.c (evaluate): Diagnose excess characters in eval input.
2858 Things like `eval(08)' used to return 0 with no diagnostic.
2860 * m4.h: Capitalize first letter of all macro arguments in
2863 * m4.c: Declare warning_status, initialize it to 0. Add new
2864 option -E, or --fatal-warnings, which sets warning_status to
2865 EXIT_FAILURE instead.
2866 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2867 EXIT_FAILURE if not otherwise done by header files.
2868 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2869 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2870 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2871 argument of all M4ERROR calls.
2872 Reported by Noah Friedman.
2874 * examples/incl-test.m4: Renamed from incl_test.m4.
2875 * examples/include.m4: Include incl-test.m4 instead of
2877 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2879 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2881 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2882 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2883 also tested it on a Sun Sparc workstation running SunOS 4.x.
2885 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2886 49.format check, abusing a `union values' argument with sprintf
2887 without selecting the proper field. Now, save the formatting type
2888 first, delaying the fetch of the corresponding argument.
2889 Reported by Joseph E. Sacco and Tom Quinn.
2891 * format.c (format): Remove const from char *fmt declaration when
2892 not HAVE_EFGCVT, because a NUL may be forced into it.
2894 * m4.h: Declare atof() when not STDC_HEADERS.
2895 Reported by Joseph E. Sacco.
2897 * Regenerate configure using Autoconf 1.11, this corrects a
2898 problem about an incorrect cpp seting on NeXT 3.1.
2899 Reported by Alexander Lehmann.
2901 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2903 * m4.h (_): Change argument from `x' to `Args'.
2905 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2907 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2908 bringing more evil than good on a few systems.
2909 Reported by Greg A. Woods.
2911 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2913 * m4.h: Rename Args() to _().
2914 * m4.h: Remove extern specifier from all function declarations.
2916 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2918 * stackovf.c: New file implementing stack-overflow detection.
2919 * configure.in: Check for getrlimit, sigaction. If all of
2920 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2921 substitute ${U}stackovf.o for STACKOVF.
2922 * acconfig.h: Declare USE_STACKOVF.
2923 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2924 * m4.h: Declare setup_stackovf_trap().
2925 * m4.c: Call setup_stackovf_trap().
2926 * tests/stackovf_test.sh: New file.
2928 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2930 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2932 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2934 Sun Jan 30 14:24:19 1994 (pinard at icule)
2936 * m4.h: Remove definition of volatile, not used anymore.
2937 Reported by Jim Meyering and Joseph E. Sacco.
2939 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2940 of `if ... else /* nothing */' for if macros.
2941 Reported by Jim Meyering.
2943 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2944 warning from gcc about `repl' possibly used before defined.
2945 Reported by Jim Meyering.
2947 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2948 Reported by Jim Meyering.
2950 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2952 * m4.h: Move the conditional definition of volatile after the
2953 inclusion of system files, because they may define it first.
2955 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2957 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2958 get around a problem with Alpha make seeing a syntax error, there.
2959 Reported by Vern Paxson.
2961 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2963 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2964 Reported by Richard Stallman.
2966 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2968 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2969 instead of AC_HAVE_FUNCS.
2970 Reported by Noah Friedman.
2972 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2974 * m4.c: Initialize show_help and show_version to zero.
2976 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2977 Use them in exit() and usage() calls.
2979 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2981 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2982 syserr() macro. Delete errref, add reference_error and M4ERROR.
2983 * m4.c: Replace errref, which was returning an input reference
2984 string, with reference_error, which prints it on standard error.
2985 * builtin.c, output.c: Use errno as second parameter to error,
2986 instead of using syserr() with %s.
2987 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2988 Doing so, the program name appears after the input reference
2989 instead of before, which eases M-x next-error processing.
2991 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2993 * checks/get-them: Escape braces with backslashes in patterns,
2994 because HPUX-9.01 awk needs this.
2995 Reported by Jim Meyering.
2997 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2999 * builtin.c: Declare "FILE *popen ();".
3001 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
3002 macros, replace error_message_prefix() declaration by errref()'s.
3003 Declare xrealloc, for use in errref().
3004 * m4.c: Delete error_message_prefix() function, add errref().
3005 * *.c: Use error() systematically in place of all error macros,
3006 now that error() flushes stdout first. Make needed adjustments.
3008 * m4.h: Remove const in sys_errlist[] declaration, it creates
3009 conflicts on SGI and Alpha.
3010 Reported by Kaveh R. Ghazi.
3012 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
3014 * m4.c: Include <getopt.h> instead of "getopt.h".
3016 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
3017 * acconfig.h: New, for documenting HAVE_EFGCVT.
3018 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
3019 use them wherever appropriate. Also use -I. for compilations.
3020 * lib/Makefile.in: Use -I.. for compilations.
3021 * *.c: Include <config.h> or "config.h".
3023 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
3024 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
3026 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
3028 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
3030 * input.c (input_init): Initialize quote and comment strings
3031 explicitely instead of calling set_quotes and set_comment: by
3032 doing so, we ensure we do not free uninitialized variables.
3034 * checks/check-them: Reverse arguments to both diff, so the
3035 expected is on the left and the obtained on the right.
3037 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
3038 macros. Delete declarations for m4error, warning, fatal and
3039 internal_error, add declaration for error_message_prefix.
3040 * m4.c: Delete m4error, warning, fatal and internal_error
3041 routines, add error_message_prefix routine.
3042 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
3043 warning with WARNING*, fatal with FATAL* and internal_error with
3045 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
3046 this is not needed anymore.
3048 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
3049 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
3050 and debug_message, add declaration for debug_message_prefix.
3051 * debug.c: Remove static specifier for FILE *debug declaration.
3052 Delete debug_print and debug_message routines, add
3053 debug_message_prefix routine.
3054 * builtin.c, debug.c: Replace debug_print routine calls with
3055 DEBUG_PRINT* macro calls.
3056 * input.c, path.c: Replace debug_message routine calls with
3057 DEBUG_MESSAGE* macro calls.
3059 * m4.h: Remove inclusion of <varargs.h>.
3060 * debug.c: Include <stdarg.h> or <varargs.h>.
3061 (trace_format): Use stdarg instead of varargs if __STDC__.
3063 * configure.in: Remove checks for vfprintf and _doprnt. These
3064 implementations use varargs tricks which are not portable enough.
3065 * lib/vfprintf.c: Deleted.
3066 * lib/_doprnt.c: Deleted.
3067 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
3068 Reported by Joel Sherrill.
3070 * path.c (add_include_directory): Use xstrdup.
3072 * builtin.c (find_builtin_by_name): Declare static.
3074 * *.[ch]: Add const to a few "char *" declarations.

3082 Reported by Nicolas Pioch.
3084 Fri Nov 12 10:02:26 1993 Francois Pinard (pinard@icule)
3086 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
3087 Reported by Joel Sherrill.
3089 * builtin.c (prefix_all_builtins): Instead of the table size, use
3090 the null entry at end for stopping the loop. It was overwritten.
3091 Reported by Andreas Schwab and Jim Meyering.
3093 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
3094 Reported by Kaveh R. Ghazi.
3096 * macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).
3097 Reported by Karl Vogel.
3099 Tue Nov 9 09:31:47 1993 Francois Pinard (pinard@icule)
3101 * m4.h: Do not define volatile if already defined.
3102 Reported by Rene' Seindal.
3104 * lib/Makefile.in: Add a forgotten ALLOCA=@ALLOCA@. Grrr!
3106 Reported by Bernhard Daeubler, Eric Backus, Hal Peterson, Hoang
3107 Uong, Ian Taylor, Kaveh R. Ghazi, Tom McConnell and Walter Wong.
3109 Mon Nov 8 21:11:44 1993 Francois Pinard (pinard@icule)
3111 * m4.h: Define strchr and strrchr in terms of index and rindex,
3112 instead of the other way around.
3113 * builtin.c, m4.c, path.c: Use strchr instead of index.
3115 * input.c (next_char): Remove a "break;" after a "return ...;".
3116 Reported by Tom McConnell.
3118 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
3122 * configure.in: Do not copy check files in the build hierarchy.
3123 * checks/check-them: Identify the m4 version being checked. For
3124 finding m4, look in $PATH instead of in the parent directory.
3125 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
3126 * checks/Makefile.in (.all-stamp): Always create check files in
3127 the source hierarchy, not anymore in the build hierarchy.
3128 (check): cd to the source hierarchy before performing checks.
3129 Do not copy nor clean COPYING anymore, take it from `..'.
3130 Reported by Tom McConnell.
3132 * Makefile.in (Makefile): Use $(SHELL).
3133 (config.status): Use $(SHELL). Use "config.status --recheck"
3134 instead of "configure --no-create", which is obsolete.
3135 Reported by Tom McConnell.
3137 Fri Nov 5 09:49:30 1993 Francois Pinard (pinard@compy.IRO.UMontreal.CA)
3139 * m4.c (usage): Use "%s" instead of "m4" in format string.
3140 Reported by Jim Meyering.
3142 * Makefile.in: Distribute mkinstalldirs.
3143 Reported by Pierre Gaumond.
3144 Reported by Jim Meyering.
3145 Reported by Tom McConnell.

3326 * Makefile.in (texclean, mostlyclean): New goals.
3328 * Makefile.in (clean): Remove clutter from ansi2knr.
3329 Reported by Pierre Gaumond.

3345 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
3348 This is still a beta release for the future GNU m4 version 1.1.
3350 * lib/alloca.c: New, from elsewhere.
3351 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3353 * m4.h: Do not define index/rindex if already defined. If
3354 FALSE/TRUE are already defined, do not redefine them, but merely
3355 define boolean typedef to int.
3357 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3358 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3359 because some C compilers do not like connectives with #ifdef.
3360 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3361 __GNUC__ and once for __STDC__.
3362 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3364 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3365 Makefile dependencies. Without it, make keeps destroying and
3366 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3368 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3369 to diversion/DIVERSION, this was a spelling error.
3371 * m4.c: Declare version[], remove #include "version.h".
3372 * version.h: Deleted.
3373 * Makefile.in: Remove references to version.h.
3375 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3376 production, by using a simpler and more robust algorithm. This
3377 solves the problem of synclines sometimes written in the middle of
3378 an output line. Delete sync_line() and output_lines variable.
3379 * m4.h: Remove sync_line prototype and output_lines declaration.
3380 * input.c (next_char), output.c (shipout_text): Remove references
3382 * input.c (push_file, pop_file): Merely put the value -1 in
3383 output_current_line instead of calling sync_line, for delaying a
3384 single `#line NUM FILE' before next output line. Do not test
3385 for sync_output, because this is unnecessary clutter.
3386 * output.c (make_divertion, insert_divertion): Idem.
3387 * input.c: Rename must_advance_line to start_of_input_line, for
3390 * debug.c (trace_header): Select a new debug line format, which
3391 better complies with GNU standards for formatting error messages.
3392 With option `-dfl', M-x next-error might be used on the output.
3393 * m4.c (vmesg): Adjust format of error output to GNU standards.
3394 * m4.texinfo: Adjust examples for `make check' to work.
3396 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3397 case for enum debug_info constants, which were all lower case.
3399 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3401 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3402 collected patches. I tried a few times using newer regex.[ch], it
3403 mysteriously stopped aborting with this one. Insecure feeling...
3404 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3406 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3408 * m4.c: Change `--no-warnings' to `--silent'.
3409 Reported by David MacKenzie.
3411 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3412 leave it off for now. See comment in m4.c for justification.
3413 Reported by David MacKenzie.
3415 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3416 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3418 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3420 * Makefile.in: Ensure recursive cleaning is done before local
3421 cleaning for all clean goals.
3423 * builtin.c (ntoa): Ensure the value is always interpreted as a
3424 signed quantity, whatever the radix is.
3426 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3428 * builtin.c, format.c, input.c: Split long lines.
3429 * m4.c: Use typedef macro_definition instead of struct
3431 * symtab.c: Use typedef symbol instead of struct symbol.
3433 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3435 * *.[ch]: Remove all trailing whitespace, in code and comments.
3437 * configure.in: Find some awk.
3438 * Makefile.in: Add $(AWK) to MDEFINES.
3439 * checks/Makefile.in: Transmit $(AWK) to get_them.
3440 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3441 awk script when switching files, because without this, mawk runs
3442 out of file descriptors.
3444 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3446 * Makefile.in (realclean): Delete m4.info*.
3447 Reported by Jim Meyering.
3449 * Makefile.in: Adjust and link with checks/Makefile.
3450 * checks/Makefile.in: New.
3451 * configure.in: Output checks/Makefile.
3453 * checks/get_them: Have the dnl header of each test more
3454 recognizable by next-error, also use a better message.
3456 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3458 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3459 And use that only if __GNUC__ since we're using it's GCC-specific
3460 semantics that tell the compiler the associated function doesn't
3463 * builtin.c (substitute): Don't use character as an array index.
3464 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3465 warnings with gcc -W -Wall on systems with qsort prototype.
3466 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3469 * eval.c (most functions): Add parentheses to assignments used
3470 as truth values go avoid warnings from gcc -Wall.
3472 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3473 any functions that don't need external scope.
3475 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3476 (many functions and arrays): Declare `const'.
3478 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3480 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3481 removing the declaration from m4.h. Also rename false to FALSE
3484 * lib/Makefile.in (Makefile): New goal.
3486 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3487 so heavily loaded. It gets more easily overridable, calling make.
3488 Reported by Jim Meyering.
3490 * Makefile.in (dist): Get .fname from the current directory name,
3491 instead of from version.h. I need updating many files manually,
3492 when the version changes, version.h is just one of them.
3494 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3496 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3497 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3498 Reported by Tom McConnell.
3500 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3502 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3503 39.cleardiv, which were describing missing or spurious newlines.
3504 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3505 do not depend on machine word size, `/bin/false' implementation,
3506 or `wc' output format. `make check' is more dependable, now.
3508 * checks/check_them: Summarize the failed tests by listing their
3509 name, at end. If none, issue `All checks successful'. Output
3510 `Checking' instead of `Input file:'.
3512 * checks/get_them, checks/check_them: Reindented.
3514 * Makefile.in (dist): chmod a+r before making the tar file.
3516 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3518 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3520 * input.c (next_token): Reinitialize token_buttom just after using
3521 it as a watermark with obstack_free. Or else, a future token, big
3522 enough for triggering reallocation of the obstack chunk, could
3523 void the initialized value of token_buttom, later causing panic in
3524 obstack_free. Rename token_buttom to token_bottom everywhere.
3526 * m4.h: Before declaring errno, first include <errno.h> and
3527 ensure that it does not define errno.
3528 Reported by Richard Stallman.
3530 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3532 * builtin.c: Define and use DECLARE macro for builtins.
3534 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3535 argument, this is a common idiom for introducing long comments.
3537 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3538 arguments. The last argument was silently ignored.
3540 * m4.c (cmd_error): Add a missing semicolon before va_end().
3542 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3544 * Makefile.in: Now handle protoized sources. Define and use U.
3545 Compile and use ansi2knr with old compilers. Update DISTFILES.
3546 Add `aclocal.m4' to `configure' dependencies.
3547 * ansi2knr.c: New, from Ghostscript distribution.
3548 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3549 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3550 * aclocal.m4: New, provide FP_PROTOTYPES.
3551 * m4.h: Conditionnaly protoized through Args, save for varags.
3552 * builtin.c: Protoized. Then:

3563 (xfree): Accept void * instead of char *.
3564 (xmalloc): Return void * instead of char *.
3565 (xrealloc): Accept and return void * instead of char *.
3566 * macro.c: Protoized.
3567 * output.c: Protoized.
3568 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3569 * symtab.c: Protoized.
3571 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3573 * m4.texinfo: Remove directory from diagnostics in 30.include,
3574 51.eval, 56.errprint and 57.m4exit tests.
3576 * m4.h: Remove declarations for int or void system functions, they
3577 cause more conflicting trouble than they make good.
3579 * configure.in: Avoid configuration header file. Add some tests.
3580 * m4.h: Remove #include "config.h".
3581 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3582 Then, rewritten for better compliance with GNU standards.
3584 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3586 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3587 because of a misplaced #endif.

3639 Reported by Richard Stallman.
3641 * config/hmake-unicos, config/s-unicos.h: New files.
3642 Reported by Hal Peterson.
3644 * eval.c (exp_term): Have N^0 return 1.
3645 Reported by Michael Fetterman.
3647 * eval.c, input.c, m4.h: Remove last comma in enums.
3648 Reported by Mike Lijewski.

3655 reports and feedback.
3657 * Uses GNU configure, taken from the gdb distribution.
3659 * Uses GNU getopt(), with long option names.
3661 * The -Q/+quiet option is added, which suppresses warnings about
3662 missing or superflous arguments to built-in macros.
