2657 Reported by John David Anglin.
2659 * src/ansi2knr.c: New version, sent by Peter Deutsch.
2660 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
2661 ANSI2KNR, depending on the fact the compiler is ANSI or not.
2662 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
2663 Remove the sed filter after ansi2knr for debug.c. Use $O instead
2664 of $U, put underline in extensions rather than in basenames. Use
2665 implicit rules, now that regularity makes this possible.
2666 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
2667 of ansi2knr whenever it is needed.
2668 * configure.in: Adjusted for correct STACKOVF substitution.
2669 * src/debug.c (trace_format): When not __STDC__, use (...) as a
2670 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

2681 * Makefile.in (all, install, uninstall): Depend on Makefile.
2683 * Makefile.in: For actions invoking $(MAKE) from within compound
2684 sh statements, exit non-zero if the sub-make fails. Otherwise,

2686 Reported by Jim Kingdon.
2688 * {,/*}Makefile.in: Use && after all cd, in case they fail.
2690 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

2720 * src/stackovf.c: Declare the handler_t typedef earlier in the
2721 code, use it for stackovf_handler.
2722 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
2723 casting sigsegv_handler.
2724 Reported by Robert Bernstein.
2726 * src/m4.c (main): Initialize program_name to argv[0] without

2738 (TAGS): Make in $(srcdir).
2740 * configure.in: Use `choke me' in test, like everywhere!
2742 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
2743 unreacheable and useless.
2745 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.

2753 * Makefile.in (distclean, realclean): Instead of recursively
2754 calling $(MAKE) for the -local part, allow parallel execution of
2755 -recursive and -local, only delay the removal of config.status,
2756 which is repeated in both goals.
2758 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
2761 * Makefile.in: Group all *clean-recursive goals in one, using sed
2762 to remove `-recursive' while calling make recursively. Also, use
2763 a subshell for each recursive $(MAKE).
2764 Reported by Jim Meyering.
2766 * src/m4.h (memcpy): Define with bcopy for BSD systems.
2767 Reported by Kaveh R. Ghazi.
2769 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2770 4.1.3 requires -ldl to link even ansik2nr, and we need a way to

2790 Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
2792 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for

2804 Reported by Jim Meyering.
2806 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)
2808 * configure.in: Correct stack overflow detection logic, taking
2809 care of systems having only incomplete implementations (like for

2829 calling a function by that name. Declare the variable.
2830 * src/m4.h: Adjust declaration for prefix_all_buitins.
2831 * src/builtin.c (builtin_init): Merge in functionality from
2832 previous prefix_all_buitins function, while making entries in the
2833 symbol table, but not modifying the builtin description itself.
2835 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2836 because *many* compilers do not accept an empty `default:'.
2837 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2838 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2840 * configure.in: Use AC_TYPE_SIGNAL.
2841 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
2842 Reported by Robert Bernstein.

2846 * Makefile.in (check): Don't.
2847 Reported by Akiko Matsushita and Jim Meyering.
2849 * src/output.c (make_room_for, output_character_helper): New

2851 a per buffer MAXIMUM_BUFFER_SIZE.
2853 * src/output.c (output_text): New function, for optimizing the
2854 output of strings of characters. Use it.

2858 * doc, src: New directories reorganizing the distribution.
2859 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
2861 * Makefile.in: Adjusted.
2862 * configure.in: Configure new Makefiles.
2864 * m4.h: Declare STRING typedef. Use it for comment and quote
2865 strings, adjusting all references. (This is the rudiments of a
2866 beginning for the eventual withdrawal of NUL terminated strings.)
2867 * output.c (shipout_text): Accept a length parameter, and use it.
2868 All callers adjusted.
2870 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2872 * m4.h: Include <unistd.h> if it exists.

2892 * output.c (freeze_diversions): New function.
2893 * m4.h: Declare freeze_diversions.
2894 * freeze.c: Document frozen file format, revise it, call
2895 freeze_diversions to add diversions to frozen format, and code to
2896 reload them properly.
2897 * m4.c: Do not undivert automatically at end when status being
2898 frozen. Do not call builtin_init when reloading frozen state.
2900 Speed up diversion processing:
2901 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2902 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2903 structure and variables, cached variables out of output_diversion,
2904 reallocate_diversion_for and OUTPUT_CHARACTER.
2905 (shipout_text, make_diversion, insert_diversion): Adapted to new
2907 (insert_file): Use better buffering.
2908 Reported by David MacKenzie.

2915 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2917 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2918 constant HASHMAX, for -H option to work better.
2920 * builtin.c (DECLARE): Simplify by using _ ().
2922 * freeze.c: New file.
2923 * Makefile.in: Compile it, distribute it.
2924 * m4.c: Recognize, document and process --freeze-state (-F) and
2925 --reload-state (-R) options. Pass a true flag to builtin_init
2926 only if no reloading some state.
2927 * builtin.c (define_builtin): Remove static specifier.
2928 (find_builtin_by_name): Remove static specifier.
2929 (builtin_init): Accept and obey a flag argument.

2941 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2943 * m4.c (long_options): Use "error-output", the dash was missing.
2944 Reported by Akiko Matsushita.
2946 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2948 * m4.h: Include <sys/types.h>.
2949 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2950 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2952 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2954 * builtin.c (dump_args): Declare len as size_t, not int.
2956 * debug.c: Prototype the forward declaration of debug_set_file.
2958 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2959 shadowing of this variable.
2960 * output.c (insert_diversion): Idem.
2962 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2963 (input_init): Duplicate default quote and comment strings.
2964 (set_quotes): Free previous quote strings in all cases. Duplicate
2965 even default quote strings.
2966 (set_comment): Free previous comment strings in all cases.

2972 * m4.c (usage): Reorganize the --help output by topic. Include a
2973 description for debugging flags.
2975 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2977 * configure.in: If sigaction is available and SA_ONSTACK defined,
2978 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2979 defined, use sigvec. Else don't compile stackovf.c.
2980 * stackovf.c (setup_stackovf_trap): Idem.
2981 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2984 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2986 * m4.c (usage): Replace printf par fputs.
2988 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2992 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2994 * configure.in: Check for sigaction and sigvec. Add a new delayed
2995 check for RLIMIT_STACK, combine in the checking for getrlimit.
2996 All those things are not universally available.
2997 * stackovf.c: Split setting up the trap handler and catching
2998 signals, for better taking care of various configure outcomes.
2999 * examples/stackovf.sh: Correct a typo.
3000 Reported by Eric Backus, Jim Avera and Jim Meyering.
3002 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
3004 * ansi2knr.c: New version sent by its author, Peter Deutsch.
3006 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
3008 * Makefile.in: Modify so parallel make will not try making
3009 lib/libm4.a twice simultaneously.
3010 Reported by Jim Meyering.
3012 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
3014 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
3015 error message, for when no code possibility exists. Even if this
3016 line is completely #ifdef'ed out, it brings a syntax error.
3017 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
3019 * Makefile.in (install): Have install depend on all too, for lib
3020 to be remade as needed.
3022 * examples/stackovf.sh: Try ksh, bsh and bash for shells
3023 providing ulimit, instead of using only ksh.
3024 Reported by Jim Avera and Joseph E. Sacco.
3026 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
3028 * Makefile.in (check): Have it depend on all instead of m4. In
3029 this way, a change in lib will be detected and processed.
3031 * builtin.c (numeric_arg): Use strtol and verify the conversion,
3032 instead of using sscanf which stops as soon as there is a
3033 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
3034 and divert(1xyzzy) were all accepted without any warning or error
3036 * m4.h: Declare strtol as long if not including stdlib.h.
3037 * configure.in: Check for limits.h, and replace strtol if missing.
3038 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
3039 * lib/strtol.c: New file, from elsewhere.
3040 Reported by Andreas Schwab.
3042 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
3044 * macro.c (expand_macro): Cast value to (boolean) prior to
3045 assigning it to traced.
3046 Reported by Tom McConnell.
3048 * Makefile.in (m4): Always make all in lib first.
3049 Reported by Jim Meyering.
3051 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
3053 * stackovf.c: Isolated OS-dependent sections; Improved portability,
3054 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
3055 handlers), and a default error message if the fault address is not
3056 available (when neither siginfo.h nor BSD sigcontext are supported).
3057 * configure.in: Changes for stackovf.h: Check for sigcontext,
3058 sigaction, sigstack, and define rlim_t as int if necessary.
3059 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
3060 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
3061 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
3063 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
3065 * configure.in: Use AC_SET_MAKE.
3066 * Makefile.in: Use @SET_MAKE@.
3067 Reported by Jim Meyering.
3069 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
3070 Reported by Ian Taylor.
3072 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
3074 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
3075 because siginfo.h is unrelated to standard headers, and siginfo.h
3076 is already checked for.
3077 Reported by Joseph E. Sacco.
3079 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
3081 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
3084 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
3086 * builtin.c (substitute): Use \& to represent this part of the
3087 string which was matched by the whole regexp, instead of
3088 representing the whole string. Any usage of \0 issues a warning
3089 and acts like \&, it will disappear in some subsequent release.
3091 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
3093 * m4.c: Complete prototype for forwarded declaration of usage.
3095 * input.c (init_macro_token): Correct own reference in error
3096 message. Previous name get_macro_func was referred to instead.
3097 (next_char): Correct own reference in error message. Previous
3098 name advance_input was referred to instead.
3100 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
3101 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
3102 and_term, not_term, logical_not_term, cmp_term, shift_term,
3103 add_term, mult_term, exp_term, unary_term, simple_term): Add
3104 prototype to forwarded declarations. Declare parameter v1 as
3105 eval_t * instead of int *. Same for local variable v2 in dyadic
3106 functions. Same for result in exp_term.
3107 * builtin.c (m4_eval): Declare value as eval_t instead of int.
3108 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
3109 unsigned_eval_t instead of unsigned int. Change casts accordingly.
3110 (shipout_int): Cast first argument of ntoa to eval_t.
3111 Reported by Thorsten Ohl.
3113 * macro.c: Complete the prototypes of forwarded expand_macro and
3115 Reported by Thorsten Ohl.
3117 * m4.h: Define voidstar as void * or char * depending on __STDC__.
3118 The Ultrix 3.1 compiler cannot do much with void pointers.
3120 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
3121 * m4.c (xfree): Replace void * by voidstar.
3122 Reported by Tom McConnell.
3124 * ansi2knr.1: New, from elsewhere.
3125 * Makefile.in (DISTFILES): Distribute ansi2knr.1
3127 * Makefile.in (stamp-h.in): Avoid running ./config.status if
3128 stamp-h does not exist yet. This avoids running it a second time
3129 just after the initial ./configure.
3130 Reported by David MacKenzie and Tom McConnell.
3132 * m4.h: Replace the enum debug_info declaration with a series of
3133 #define's. The Ultrix 3.1 compiler would otherwise need casting
3134 (int) to most references, when used in expressions.
3135 Reported by Tom McConnell.
3137 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
3139 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
3140 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
3141 calls the compiler. Previously, FP_PROTOTYPES was only calling
3142 the preprocessor; by not being subject to CFLAGS, this was
3143 discouraging those flags asking for ANSI compilation.
3144 * acconfig.h: Document HAVE_PROTOTYPES.
3145 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
3146 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
3147 Reported by Eric Backus.
3149 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
3150 from the environment. Default CFLAGS to -g if not set.
3151 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
3152 * lib/Makefile.in: Have CFLAGS substituted from configure.
3153 Reported by Eric Backus and Tom McConnell.
3155 * configure.in: m4_undefine changeword before using AC_ENABLE.
3157 * m4.h: Declare prototypes for error (for ANSI compilers only),
3158 prefix_all_builtins and reference_error.
3159 Reported by Tom McConnell.
3161 * input.c (set_word_regexp): Do not try to initialize the array

3223 Reported by Bengt Mertensson.
3225 * eval.c (evaluate): Diagnose excess characters in eval input.
3226 Things like `eval(08)' used to return 0 with no diagnostic.
3228 * m4.h: Capitalize first letter of all macro arguments in
3231 * m4.c: Declare warning_status, initialize it to 0. Add new
3232 option -E, or --fatal-warnings, which sets warning_status to

3247 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
3249 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
3250 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
3251 also tested it on a Sun Sparc workstation running SunOS 4.x.
3253 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
3254 49.format check, abusing a `union values' argument with sprintf
3255 without selecting the proper field. Now, save the formatting type
3256 first, delaying the fetch of the corresponding argument.
3257 Reported by Joseph E. Sacco and Tom Quinn.
3259 * format.c (format): Remove const from char *fmt declaration when
3260 not HAVE_EFGCVT, because a NUL may be forced into it.

3309 Reported by Jim Meyering.
3311 * builtin.c (m4_regexp): Reorganize the code for avoiding a
3312 warning from gcc about `repl' possibly used before defined.
3313 Reported by Jim Meyering.
3315 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
3316 Reported by Jim Meyering.
3318 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
3320 * m4.h: Move the conditional definition of volatile after the
3321 inclusion of system files, because they may define it first.
3323 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
3325 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
3326 get around a problem with Alpha make seeing a syntax error, there.

3342 * m4.c: Initialize show_help and show_version to zero.
3344 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
3345 Use them in exit() and usage() calls.
3347 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
3349 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
3350 syserr() macro. Delete errref, add reference_error and M4ERROR.
3351 * m4.c: Replace errref, which was returning an input reference
3352 string, with reference_error, which prints it on standard error.
3353 * builtin.c, output.c: Use errno as second parameter to error,
3354 instead of using syserr() with %s.
3355 * *.c: Use M4ERROR instead of error: no more errref() with %s.
3356 Doing so, the program name appears after the input reference
3357 instead of before, which eases M-x next-error processing.
3359 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
3361 * checks/get-them: Escape braces with backslashes in patterns,

3371 Declare xrealloc, for use in errref().
3372 * m4.c: Delete error_message_prefix() function, add errref().
3373 * *.c: Use error() systematically in place of all error macros,
3374 now that error() flushes stdout first. Make needed adjustments.
3376 * m4.h: Remove const in sys_errlist[] declaration, it creates
3377 conflicts on SGI and Alpha.
3378 Reported by Kaveh R. Ghazi.
3380 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

3398 * input.c (input_init): Initialize quote and comment strings
3399 explicitely instead of calling set_quotes and set_comment: by
3400 doing so, we ensure we do not free uninitialized variables.

3403 expected is on the left and the obtained on the right.
3405 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
3406 macros. Delete declarations for m4error, warning, fatal and
3407 internal_error, add declaration for error_message_prefix.
3408 * m4.c: Delete m4error, warning, fatal and internal_error
3409 routines, add error_message_prefix routine.
3410 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
3411 warning with WARNING*, fatal with FATAL* and internal_error with
3413 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
3414 this is not needed anymore.
3416 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and

3420 Delete debug_print and debug_message routines, add
3421 debug_message_prefix routine.
3422 * builtin.c, debug.c: Replace debug_print routine calls with
3423 DEBUG_PRINT* macro calls.

3429 (trace_format): Use stdarg instead of varargs if __STDC__.
3431 * configure.in: Remove checks for vfprintf and _doprnt. These
3432 implementations use varargs tricks which are not portable enough.

3455 Reported by Joel Sherrill.
3457 * builtin.c (prefix_all_builtins): Instead of the table size, use
3458 the null entry at end for stopping the loop. It was overwritten.

3680 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
3681 (libm4.a): Remove the library before creating it.
3682 (distclean): Remove tags and TAGS too.
3684 Wed Dec 23 12:46:55 1992 Francois Pinard (pinard at icule)
3686 * Makefile.in (dvi, m4.dvi): New goals.
3688 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
3689 macro.c, output.c, path.c, symtab.c: Change Copyright from
3690 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
3692 * examples/divert.m4: Deleted, this bug has been corrected.
3694 * Makefile.in (texclean, mostlyclean): New goals.
3696 * Makefile.in (clean): Remove clutter from ansi2knr.
3697 Reported by Pierre Gaumond.
3698 Reported by Greg A. Woods.
3700 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
3702 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
3703 might well use CFLAGS is s/he needs it.
3705 * Makefile.in: Allow installation of info files from a separate
3707 Reported by Jason Merrill.
3708 Reported by David MacKenzie.
3709 Reported by Skip Montanaro.
3710 Reported by Erez Zadok.
3711 Reported by Assar Westerlund.
3713 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
3716 This is still a beta release for the future GNU m4 version 1.1.
3718 * lib/alloca.c: New, from elsewhere.
3719 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3721 * m4.h: Do not define index/rindex if already defined. If
3722 FALSE/TRUE are already defined, do not redefine them, but merely
3723 define boolean typedef to int.
3725 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3726 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3727 because some C compilers do not like connectives with #ifdef.
3728 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3729 __GNUC__ and once for __STDC__.
3730 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3732 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3733 Makefile dependencies. Without it, make keeps destroying and
3734 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3736 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3737 to diversion/DIVERSION, this was a spelling error.
3739 * m4.c: Declare version[], remove #include "version.h".
3740 * version.h: Deleted.
3741 * Makefile.in: Remove references to version.h.
3743 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3744 production, by using a simpler and more robust algorithm. This
3745 solves the problem of synclines sometimes written in the middle of
3746 an output line. Delete sync_line() and output_lines variable.
3747 * m4.h: Remove sync_line prototype and output_lines declaration.
3748 * input.c (next_char), output.c (shipout_text): Remove references
3750 * input.c (push_file, pop_file): Merely put the value -1 in
3751 output_current_line instead of calling sync_line, for delaying a
3752 single `#line NUM FILE' before next output line. Do not test
3753 for sync_output, because this is unnecessary clutter.
3754 * output.c (make_divertion, insert_divertion): Idem.
3755 * input.c: Rename must_advance_line to start_of_input_line, for
3758 * debug.c (trace_header): Select a new debug line format, which
3759 better complies with GNU standards for formatting error messages.
3760 With option `-dfl', M-x next-error might be used on the output.
3761 * m4.c (vmesg): Adjust format of error output to GNU standards.
3762 * m4.texinfo: Adjust examples for `make check' to work.
3764 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3765 case for enum debug_info constants, which were all lower case.
3767 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3769 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3770 collected patches. I tried a few times using newer regex.[ch], it
3771 mysteriously stopped aborting with this one. Insecure feeling...
3772 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3774 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3776 * m4.c: Change `--no-warnings' to `--silent'.
3777 Reported by David MacKenzie.
3779 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3780 leave it off for now. See comment in m4.c for justification.
3781 Reported by David MacKenzie.
3783 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3784 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3786 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3788 * Makefile.in: Ensure recursive cleaning is done before local
3789 cleaning for all clean goals.
3791 * builtin.c (ntoa): Ensure the value is always interpreted as a
3792 signed quantity, whatever the radix is.
3794 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3796 * builtin.c, format.c, input.c: Split long lines.
3797 * m4.c: Use typedef macro_definition instead of struct
3799 * symtab.c: Use typedef symbol instead of struct symbol.
3801 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3803 * *.[ch]: Remove all trailing whitespace, in code and comments.
3805 * configure.in: Find some awk.
3806 * Makefile.in: Add $(AWK) to MDEFINES.
3807 * checks/Makefile.in: Transmit $(AWK) to get_them.
3808 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3809 awk script when switching files, because without this, mawk runs
3810 out of file descriptors.
3812 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3814 * Makefile.in (realclean): Delete m4.info*.
3815 Reported by Jim Meyering.
3817 * Makefile.in: Adjust and link with checks/Makefile.
3818 * checks/Makefile.in: New.
3819 * configure.in: Output checks/Makefile.
3821 * checks/get_them: Have the dnl header of each test more
3822 recognizable by next-error, also use a better message.
3824 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3826 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3827 And use that only if __GNUC__ since we're using it's GCC-specific
3828 semantics that tell the compiler the associated function doesn't
3831 * builtin.c (substitute): Don't use character as an array index.
3832 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3833 warnings with gcc -W -Wall on systems with qsort prototype.
3834 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3837 * eval.c (most functions): Add parentheses to assignments used
3838 as truth values go avoid warnings from gcc -Wall.
3840 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3841 any functions that don't need external scope.
3843 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3844 (many functions and arrays): Declare `const'.
3846 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3848 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3849 removing the declaration from m4.h. Also rename false to FALSE
3852 * lib/Makefile.in (Makefile): New goal.
3854 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3855 so heavily loaded. It gets more easily overridable, calling make.
3856 Reported by Jim Meyering.
3858 * Makefile.in (dist): Get .fname from the current directory name,
3859 instead of from version.h. I need updating many files manually,
3860 when the version changes, version.h is just one of them.
3862 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3864 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3865 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3866 Reported by Tom McConnell.
3868 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3870 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3871 39.cleardiv, which were describing missing or spurious newlines.
3872 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3873 do not depend on machine word size, `/bin/false' implementation,
3874 or `wc' output format. `make check' is more dependable, now.
3876 * checks/check_them: Summarize the failed tests by listing their
3877 name, at end. If none, issue `All checks successful'. Output
3878 `Checking' instead of `Input file:'.
3880 * checks/get_them, checks/check_them: Reindented.
3882 * Makefile.in (dist): chmod a+r before making the tar file.
3884 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3886 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3888 * input.c (next_token): Reinitialize token_buttom just after using
3889 it as a watermark with obstack_free. Or else, a future token, big
3890 enough for triggering reallocation of the obstack chunk, could
3891 void the initialized value of token_buttom, later causing panic in
3892 obstack_free. Rename token_buttom to token_bottom everywhere.
3894 * m4.h: Before declaring errno, first include <errno.h> and
3895 ensure that it does not define errno.
3896 Reported by Richard Stallman.
3898 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3900 * builtin.c: Define and use DECLARE macro for builtins.
3902 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3903 argument, this is a common idiom for introducing long comments.
3905 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3906 arguments. The last argument was silently ignored.
3908 * m4.c (cmd_error): Add a missing semicolon before va_end().
3910 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3912 * Makefile.in: Now handle protoized sources. Define and use U.
3913 Compile and use ansi2knr with old compilers. Update DISTFILES.
3914 Add `aclocal.m4' to `configure' dependencies.
3915 * ansi2knr.c: New, from Ghostscript distribution.
3916 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3917 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3918 * aclocal.m4: New, provide FP_PROTOTYPES.
3919 * m4.h: Conditionnaly protoized through Args, save for varags.
3920 * builtin.c: Protoized. Then:
3921 Include <sys/types.h> if size_t is not defined, before "regex.h".
3922 (m4_ifelse): Fetch built-in name properly for diagnostic.
3923 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
3924 (m4_regexp): Add const to `msg' declaration.
3925 (m4_patsubst): Add const to `msg' declaration.
3926 * debug.c: Protoized, save for varargs.
3927 * eval.c: Protoized.
3928 * format.c: Protoized.
3929 * input.c: Protoized.
3930 * m4.c: Protoized, save for varargs. Then:
3931 (xfree): Accept void * instead of char *.
3932 (xmalloc): Return void * instead of char *.
3933 (xrealloc): Accept and return void * instead of char *.
3934 * macro.c: Protoized.
3935 * output.c: Protoized.
3936 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3937 * symtab.c: Protoized.
3939 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3941 * m4.texinfo: Remove directory from diagnostics in 30.include,
3942 51.eval, 56.errprint and 57.m4exit tests.
3944 * m4.h: Remove declarations for int or void system functions, they
3945 cause more conflicting trouble than they make good.
3947 * configure.in: Avoid configuration header file. Add some tests.
3948 * m4.h: Remove #include "config.h".
3949 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3950 Then, rewritten for better compliance with GNU standards.
3952 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3954 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3955 because of a misplaced #endif.
3957 * Many *.[hc] files: Correct intra-line spacing here and there,
3958 according to GNU indent 1.6 advice.
3960 * configure.in: New, using Autoconf 1.2.
3961 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
3962 * Delete old configure.in, configure, etc/configure.in,
3963 etc/configure, lib/configure.in, lib/configure and config/*.

3971 * version.h: De-automatize, force value in.
3973 * m4.c: Changes in order to use a newer getopt.h.
3974 Reported by David MacKenzie.
3976 * checks/: New name for examples/.
3977 * checks/get_them: New location for etc/get_examples.
3978 * checks/check_them: New location for etc/check_examples.

3984 Tue Mar 10 00:29:46 1992 Francois Pinard (pinard at icule)
3986 * Makefile.in (check): Add m4 as dependency.
3988 * m4.c: Accept --no-warnings instead of --no_warnings, and
3989 --no-gnu-extensions instead of --no_gnu_extensions. Make the
3990 usage message more informative.
3991 Reported by David MacKenzie.

4007 Reported by Richard Stallman.
4009 * config/hmake-unicos, config/s-unicos.h: New files.
4010 Reported by Hal Peterson.
4012 * eval.c (exp_term): Have N^0 return 1.
4013 Reported by Michael Fetterman.
4015 * eval.c, input.c, m4.h: Remove last comma in enums.
4016 Reported by Mike Lijewski.

4034 * The built-in format can now be configured to use sprintf as
4035 the formatting engine, for systems without [efg]cvt(3).
4037 * GNU library code is moved to the ./lib subdirectory; other
4038 utility files are now in ./etc.

4045 Francois Pinard and Roland H. Pesch for providing me with reports.
4047 * The builtins incr and decr are now implemented without use of
4050 * The builtin indir is added, to allow for indirect macro calls
4051 (allows use of "illegal" macro names).
4053 * The debugging and tracing facilities has been enhanced
4054 considerably. See the manual for details.
4056 * The -tMACRO option is added, marks MACRO for tracing as soon
4059 * Builtins are traced after renaming iff they were before.
