1127 xvasprintf.
1128 * src/format.c [HAVE_EFGCVT]: Delete this code, and use *printf

1184 time with changequote. Document a traditional incompatibility
1185 with partial input spanning file boundaries.

1188 start with lower case, and don't end sentence with punctuation.
1189 * src/debug.c (trace_pre): Update message wording.

1665 Also, some of the files here were never updated from the previous
1666 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
1667 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.

1686 (cvs-release): Don't mention manual.html.
1687 (fetch): Get latest gendocs files.
1688 (web-manual): Rewritten to use gendoc for multiformat manuals.

1690 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1691 preserving, but case insensitive, so generating html docs per node
1692 clashes between Index.html, the node file, and index.html, the
1693 top-level of the document tree...
1694 (Index macro): ...so renamed to this. Changed all references.

1751 on Windows, so that the frozen file reader will work.
1752 Reported by Josef T. Burger.
1754 * src/m4.c (main): Modernise the --version output.
1756 2005-02-03 Gary V. Vaughan <gary@gnu.org>

1777 * doc/Makefile.in (stamp-vti): Ditto.
1778 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for

1784 * src/output.c (mkstemp): Make non-static, and build regardless of
1785 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1786 * NEWS: Update.

1818 relies on this.
1819 * src/builtin.c (m4_esyscmd): Clear errno before calling popen.
1820 (m4_maketemp): Clear errno before calling mkstemp.
1821 * src/path.c (path_search): Don't let "free" trash errno when
1822 returning NULL.
1823 * src/output.c (insert_file): Don't assume errno has a valid
1824 value simply because fread returns zero. This fixes a
1825 portability bug reported by Marion Hakanson in
1826 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

1873 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1874 empty file rather than to a nonexistent file. This closes a common
1875 security hole.
1876 * src/builtin.c (m4_maketemp): Implement the above, by using
1877 mkstemp rather than mktemp. (trivial change)
1879 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1881 * src/builtin.c (expand_ranges): Added break after trailing dash.

1899 Reported by Alexander Lehmann.
1901 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
1903 * src/macro.c (collect_arguments): Cast obstack arguments to
1904 (voidstar), so avoiding compiler warnings.
1905 Reported by Joseph E. Sacco.
1907 * src/freeze.c (produce_frozen_state): Cast printed lengths to

1912 * src/symtab.c (free_symbol): Idem.

1927 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1928 defines __STDC__ to 0, for indicating it is *not* ANSI!
1929 Reported by Kaveh R. Ghazi.
1931 * configure.in: Added obsolescent tests for AIX and Minix.
1933 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
1934 which texclean does not exist anymore.
1935 Reported by Eric Backus, Jim Meyering, John David Anglin and

1946 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1947 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1948 of $U, put underline in extensions rather than in basenames. Use
1949 implicit rules, now that regularity makes this possible.
1950 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1951 of ansi2knr whenever it is needed.
1952 * configure.in: Adjusted for correct STACKOVF substitution.
1953 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1954 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

1958 Reported by David MacKenzie.

1970 Reported by Jim Kingdon.
1972 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1974 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

1994 Reported by David MacKenzie.
1996 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)

1999 configure does it automatically.
2000 Reported by Jim Meyering.
2002 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)

2021 * lib/Makefile.in (mostlyclean): Added.
2022 (TAGS): Make in $(srcdir).
2024 * configure.in: Use `choke me' in test, like everywhere!
2026 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
2027 unreacheable and useless.

2034 * Makefile.in: Make TAGS in lib also, not just in src.
2035 Reported by Karl Berry.
2037 * Makefile.in (distclean, realclean): Instead of recursively
2038 calling $(MAKE) for the -local part, allow parallel execution of
2039 -recursive and -local, only delay the removal of config.status,
2040 which is repeated in both goals.
2041 \f

2044 * Release 1.3.
2046 * Makefile.in: Group all *clean-recursive goals in one, using sed
2047 to remove `-recursive' while calling make recursively. Also, use

2052 Reported by Kaveh R. Ghazi.
2054 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2055 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
2056 specify it.
2058 * configure.in: Use date instead of touch for stamp-h.
2059 * Makefile.in (stamp-h.in): Idem.
2061 * Makefile.in (distclean, realclean): Force serial execution of

2075 Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
2077 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
2078 ./install.sh will not be correctly referred to in sub-Makefiles.

2094 care of systems having only incomplete implementations (like for
2095 Pyramid 9820 OSx 5.0d).
2096 Reported by Kaveh R. Ghazi.
2098 * src/Makefile.in (TAGS): Remote -t from etags call.
2100 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)

2115 * src/m4.h: Adjust declaration for prefix_all_buitins.
2116 * src/builtin.c (builtin_init): Merge in functionality from
2117 previous prefix_all_buitins function, while making entries in the

2120 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2121 because *many* compilers do not accept an empty `default:'.
2122 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2123 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2125 * configure.in: Use AC_TYPE_SIGNAL.
2126 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
2127 Reported by Robert Bernstein.
2129 * checks/Makefile.in (check): Modify PATH so check-them will find
2130 m4 in the src directory.
2131 * Makefile.in (check): Don't.
2132 Reported by Akiko Matsushita and Jim Meyering.

2144 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
2145 files.
2146 * Makefile.in: Adjusted.
2147 * configure.in: Configure new Makefiles.
2149 * m4.h: Declare STRING typedef. Use it for comment and quote
2150 strings, adjusting all references. (This is the rudiments of a
2151 beginning for the eventual withdrawal of NUL terminated strings.)
2152 * output.c (shipout_text): Accept a length parameter, and use it.
2153 All callers adjusted.
2155 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2157 * m4.h: Include <unistd.h> if it exists.

2177 * output.c (freeze_diversions): New function.
2178 * m4.h: Declare freeze_diversions.
2179 * freeze.c: Document frozen file format, revise it, call

2181 reload them properly.
2182 * m4.c: Do not undivert automatically at end when status being
2183 frozen. Do not call builtin_init when reloading frozen state.
2185 Speed up diversion processing:
2186 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2187 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2188 structure and variables, cached variables out of output_diversion,
2189 reallocate_diversion_for and OUTPUT_CHARACTER.
2190 (shipout_text, make_diversion, insert_diversion): Adapted to new
2191 structures.
2192 (insert_file): Use better buffering.
2193 Reported by David MacKenzie.

2198 dist works from another build directory.
2200 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2202 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2203 constant HASHMAX, for -H option to work better.

2207 * freeze.c: New file.
2208 * Makefile.in: Compile it, distribute it.
2209 * m4.c: Recognize, document and process --freeze-state (-F) and

2229 Reported by Akiko Matsushita.
2231 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2233 * m4.h: Include <sys/types.h>.
2234 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2235 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2236 int.
2237 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2238 as size_t, not int.
2239 * builtin.c (dump_args): Declare len as size_t, not int.
2241 * debug.c: Prototype the forward declaration of debug_set_file.
2243 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2244 shadowing of this variable.
2245 * output.c (insert_diversion): Idem.
2247 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2248 (input_init): Duplicate default quote and comment strings.

2257 * m4.c (usage): Reorganize the --help output by topic. Include a
2258 description for debugging flags.
2260 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2262 * configure.in: If sigaction is available and SA_ONSTACK defined,
2263 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2264 defined, use sigvec. Else don't compile stackovf.c.
2265 * stackovf.c (setup_stackovf_trap): Idem.
2266 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2267 and Simon Leinen.
2269 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2271 * m4.c (usage): Replace printf par fputs.
2272 \f
2273 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2275 * Release 1.2
2277 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2279 * configure.in: Check for sigaction and sigvec. Add a new delayed
2280 check for RLIMIT_STACK, combine in the checking for getrlimit.
2281 All those things are not universally available.
2282 * stackovf.c: Split setting up the trap handler and catching
2283 signals, for better taking care of various configure outcomes.
2284 * examples/stackovf.sh: Correct a typo.
2285 Reported by Eric Backus, Jim Avera and Jim Meyering.
2287 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2289 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2291 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2293 * Makefile.in: Modify so parallel make will not try making
2294 lib/libm4.a twice simultaneously.
2295 Reported by Jim Meyering.
2297 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2299 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2300 error message, for when no code possibility exists. Even if this
2301 line is completely #ifdef'ed out, it brings a syntax error.
2302 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2304 * Makefile.in (install): Have install depend on all too, for lib
2305 to be remade as needed.
2307 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2308 providing ulimit, instead of using only ksh.
2309 Reported by Jim Avera and Joseph E. Sacco.
2311 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2313 * Makefile.in (check): Have it depend on all instead of m4. In
2314 this way, a change in lib will be detected and processed.
2316 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2317 instead of using sscanf which stops as soon as there is a
2318 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2319 and divert(1xyzzy) were all accepted without any warning or error
2320 messages.
2321 * m4.h: Declare strtol as long if not including stdlib.h.
2322 * configure.in: Check for limits.h, and replace strtol if missing.
2323 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2324 * lib/strtol.c: New file, from elsewhere.
2325 Reported by Andreas Schwab.
2327 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2329 * macro.c (expand_macro): Cast value to (boolean) prior to
2330 assigning it to traced.
2331 Reported by Tom McConnell.
2333 * Makefile.in (m4): Always make all in lib first.
2334 Reported by Jim Meyering.
2336 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2338 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2339 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2340 handlers), and a default error message if the fault address is not
2341 available (when neither siginfo.h nor BSD sigcontext are supported).
2342 * configure.in: Changes for stackovf.h: Check for sigcontext,
2343 sigaction, sigstack, and define rlim_t as int if necessary.
2344 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2345 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2346 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2348 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2350 * configure.in: Use AC_SET_MAKE.
2351 * Makefile.in: Use @SET_MAKE@.
2352 Reported by Jim Meyering.
2354 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2355 Reported by Ian Taylor.
2357 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2359 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2360 because siginfo.h is unrelated to standard headers, and siginfo.h
2361 is already checked for.
2362 Reported by Joseph E. Sacco.
2364 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2365 PROTOTYPES.
2366 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2367 AC_PROTOTYPES.
2369 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2371 * builtin.c (substitute): Use \& to represent this part of the
2372 string which was matched by the whole regexp, instead of
2373 representing the whole string. Any usage of \0 issues a warning
2374 and acts like \&, it will disappear in some subsequent release.
2376 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2378 * m4.c: Complete prototype for forwarded declaration of usage.
2380 * input.c (init_macro_token): Correct own reference in error
2381 message. Previous name get_macro_func was referred to instead.
2382 (next_char): Correct own reference in error message. Previous
2383 name advance_input was referred to instead.
2385 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2386 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2387 and_term, not_term, logical_not_term, cmp_term, shift_term,
2388 add_term, mult_term, exp_term, unary_term, simple_term): Add
2389 prototype to forwarded declarations. Declare parameter v1 as
2390 eval_t * instead of int *. Same for local variable v2 in dyadic
2391 functions. Same for result in exp_term.
2392 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2393 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2394 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2395 (shipout_int): Cast first argument of ntoa to eval_t.
2396 Reported by Thorsten Ohl.
2398 * macro.c: Complete the prototypes of forwarded expand_macro and
2399 expand_token.
2400 Reported by Thorsten Ohl.
2402 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2403 The Ultrix 3.1 compiler cannot do much with void pointers.
2405 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2406 * m4.c (xfree): Replace void * by voidstar.
2407 Reported by Tom McConnell.
2409 * ansi2knr.1: New, from elsewhere.
2410 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2412 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2413 stamp-h does not exist yet. This avoids running it a second time
2414 just after the initial ./configure.
2415 Reported by David MacKenzie and Tom McConnell.
2417 * m4.h: Replace the enum debug_info declaration with a series of
2418 #define's. The Ultrix 3.1 compiler would otherwise need casting
2419 (int) to most references, when used in expressions.
2420 Reported by Tom McConnell.
2422 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2424 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2425 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2426 calls the compiler. Previously, FP_PROTOTYPES was only calling
2427 the preprocessor; by not being subject to CFLAGS, this was
2428 discouraging those flags asking for ANSI compilation.
2429 * acconfig.h: Document HAVE_PROTOTYPES.
2430 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2431 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2432 Reported by Eric Backus.
2434 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2435 from the environment. Default CFLAGS to -g if not set.
2436 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2437 * lib/Makefile.in: Have CFLAGS substituted from configure.
2438 Reported by Eric Backus and Tom McConnell.
2440 * configure.in: m4_undefine changeword before using AC_ENABLE.
2442 * m4.h: Declare prototypes for error (for ANSI compilers only),
2443 prefix_all_builtins and reference_error.
2444 Reported by Tom McConnell.
2446 * input.c (set_word_regexp): Do not try to initialize the array
2447 test from a string, this does not work with non-ANSI compilers.
2448 Reported by Eric Backus.
2450 * Makefile.in (dist): Clean examples/ before saving it.
2451 (distclean-local): Also remove stamp-h.
2452 Reported by Eric Backus.
2454 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2455 non ANSI compilers.
2456 Reported by Tom McConnell.
2458 * checks/Makefile.in (clean): Depends on mostlyclean.
2459 (mostlyclean): New goal.
2461 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2463 * Makefile.in (DISTFILES): Distribute install.sh.
2464 * install.sh: New file, copied from elsewhere.
2465 Reported by Assar Westerlund and Kaveh R. Ghazi.
2467 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2469 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2470 * acconfig.h: Explain ENABLE_CHANGEWORD.
2472 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2473 from code provided by Pete Chown]
2474 * m4.h: Add original_text field to u_t variant of union u.
2475 Declare TOKEN_DATA_FUNC macro.
2476 * builtin.c: Declare changeword.
2477 (m4_changeword): New function.
2478 * input.c: Include "regex.h", define variables with word regexps.
2479 (input_init): Initialize the word regexp.
2480 (set_word_regexp): New.
2481 (next_token): Declare local variables, use the previous code if
2482 default_word_regexp is true. Else, match using a new code. Save
2483 the original text.
2484 * macro.c (expand_token): Ship out original text if not a macro
2485 name.
2486 Reported by Krste Asanovic and Pete Chown.
2488 [These modifs all depend upon ENABLE_CHANGEWORD]
2489 * m4.h: Declare external user_word_regexp.
2490 * m4.c: Declare user_word_regexp, and initialize it from
2491 --word-regexp or -W, or NULL if not specified.
2492 * input.c: Use user_word_regexp if specified, instead of
2493 DEFAULT_WORD_REGEXP.
2495 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2496 agree with it.
2498 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2499 * checks/Makefile.in: Empty the suffix list.
2500 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2502 * m4.c: Declare nesting_limit and initialize it to 250.
2503 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2504 value.
2505 * m4.h: Declare nesting_limit as external.
2506 * macro.c (expand_macro): Stop execution whenever nesting limit
2507 is exceeded.
2508 Reported by Bengt Mertensson.
2510 * eval.c (evaluate): Diagnose excess characters in eval input.
2511 Things like `eval(08)' used to return 0 with no diagnostic.
2513 * m4.h: Capitalize first letter of all macro arguments in
2514 definitions.
2516 * m4.c: Declare warning_status, initialize it to 0. Add new
2517 option -E, or --fatal-warnings, which sets warning_status to
2518 EXIT_FAILURE instead.
2519 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2520 EXIT_FAILURE if not otherwise done by header files.
2521 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.

2532 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2534 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2535 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2536 also tested it on a Sun Sparc workstation running SunOS 4.x.
2538 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2539 49.format check, abusing a `union values' argument with sprintf
2540 without selecting the proper field. Now, save the formatting type
2541 first, delaying the fetch of the corresponding argument.
2542 Reported by Joseph E. Sacco and Tom Quinn.
2544 * format.c (format): Remove const from char *fmt declaration when
2545 not HAVE_EFGCVT, because a NUL may be forced into it.

2548 Reported by Joseph E. Sacco.
2550 * Regenerate configure using Autoconf 1.11, this corrects a

2575 * acconfig.h: Declare USE_STACKOVF.
2576 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2577 * m4.h: Declare setup_stackovf_trap().

2589 * m4.h: Remove definition of volatile, not used anymore.
2590 Reported by Jim Meyering and Joseph E. Sacco.

2594 Reported by Jim Meyering.
2596 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2597 warning from gcc about `repl' possibly used before defined.
2598 Reported by Jim Meyering.
2600 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2601 Reported by Jim Meyering.
2603 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2605 * m4.h: Move the conditional definition of volatile after the
2606 inclusion of system files, because they may define it first.
2608 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2610 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to

2627 * m4.c: Initialize show_help and show_version to zero.
2629 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2630 Use them in exit() and usage() calls.
2632 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2634 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2635 syserr() macro. Delete errref, add reference_error and M4ERROR.
2636 * m4.c: Replace errref, which was returning an input reference
2637 string, with reference_error, which prints it on standard error.
2638 * builtin.c, output.c: Use errno as second parameter to error,
2639 instead of using syserr() with %s.
2640 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2641 Doing so, the program name appears after the input reference
2642 instead of before, which eases M-x next-error processing.
2644 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2646 * checks/get-them: Escape braces with backslashes in patterns,

2656 Declare xrealloc, for use in errref().
2657 * m4.c: Delete error_message_prefix() function, add errref().
2658 * *.c: Use error() systematically in place of all error macros,
2659 now that error() flushes stdout first. Make needed adjustments.
2661 * m4.h: Remove const in sys_errlist[] declaration, it creates
2662 conflicts on SGI and Alpha.
2663 Reported by Kaveh R. Ghazi.
2665 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2683 * input.c (input_init): Initialize quote and comment strings
2684 explicitely instead of calling set_quotes and set_comment: by

2688 expected is on the left and the obtained on the right.
2690 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2691 macros. Delete declarations for m4error, warning, fatal and
2692 internal_error, add declaration for error_message_prefix.
2693 * m4.c: Delete m4error, warning, fatal and internal_error
2694 routines, add error_message_prefix routine.
2695 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2696 warning with WARNING*, fatal with FATAL* and internal_error with
2697 INTERNAL_ERROR*.
2698 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2699 this is not needed anymore.
2701 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
2702 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print

2705 Delete debug_print and debug_message routines, add
2706 debug_message_prefix routine.
2707 * builtin.c, debug.c: Replace debug_print routine calls with

2714 (trace_format): Use stdarg instead of varargs if __STDC__.
2716 * configure.in: Remove checks for vfprintf and _doprnt. These
2717 implementations use varargs tricks which are not portable enough.

2719 * lib/_doprnt.c: Deleted.
2720 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.

2740 Reported by Joel Sherrill.
2742 * builtin.c (prefix_all_builtins): Instead of the table size, use
2743 the null entry at end for stopping the loop. It was overwritten.
2744 Reported by Andreas Schwab and Jim Meyering.

3014 __GNUC__ and once for __STDC__.
3015 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3017 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3018 Makefile dependencies. Without it, make keeps destroying and
3019 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3021 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3022 to diversion/DIVERSION, this was a spelling error.
3024 * m4.c: Declare version[], remove #include "version.h".
3025 * version.h: Deleted.
3026 * Makefile.in: Remove references to version.h.
3028 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3029 production, by using a simpler and more robust algorithm. This
3030 solves the problem of synclines sometimes written in the middle of
3031 an output line. Delete sync_line() and output_lines variable.
3032 * m4.h: Remove sync_line prototype and output_lines declaration.
3033 * input.c (next_char), output.c (shipout_text): Remove references
3034 to output_lines.
3035 * input.c (push_file, pop_file): Merely put the value -1 in
3036 output_current_line instead of calling sync_line, for delaying a
3037 single `#line NUM FILE' before next output line. Do not test
3038 for sync_output, because this is unnecessary clutter.
3039 * output.c (make_divertion, insert_divertion): Idem.
3040 * input.c: Rename must_advance_line to start_of_input_line, for
3041 consistency.
3043 * debug.c (trace_header): Select a new debug line format, which
3044 better complies with GNU standards for formatting error messages.
3045 With option `-dfl', M-x next-error might be used on the output.
3046 * m4.c (vmesg): Adjust format of error output to GNU standards.
3047 * m4.texinfo: Adjust examples for `make check' to work.
3049 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3050 case for enum debug_info constants, which were all lower case.
3052 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3053 re_search_2.
3054 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3055 collected patches. I tried a few times using newer regex.[ch], it
3056 mysteriously stopped aborting with this one. Insecure feeling...
3057 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3059 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3061 * m4.c: Change `--no-warnings' to `--silent'.
3062 Reported by David MacKenzie.
3064 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3065 leave it off for now. See comment in m4.c for justification.
3066 Reported by David MacKenzie.
3068 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3069 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3071 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3073 * Makefile.in: Ensure recursive cleaning is done before local
3074 cleaning for all clean goals.
3076 * builtin.c (ntoa): Ensure the value is always interpreted as a
3077 signed quantity, whatever the radix is.
3079 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3081 * builtin.c, format.c, input.c: Split long lines.
3082 * m4.c: Use typedef macro_definition instead of struct
3083 macro_definition.
3084 * symtab.c: Use typedef symbol instead of struct symbol.
3086 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3088 * *.[ch]: Remove all trailing whitespace, in code and comments.
3090 * configure.in: Find some awk.
3091 * Makefile.in: Add $(AWK) to MDEFINES.
3092 * checks/Makefile.in: Transmit $(AWK) to get_them.
3093 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3094 awk script when switching files, because without this, mawk runs
3095 out of file descriptors.
3097 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3099 * Makefile.in (realclean): Delete m4.info*.
3100 Reported by Jim Meyering.
3102 * Makefile.in: Adjust and link with checks/Makefile.
3103 * checks/Makefile.in: New.
3104 * configure.in: Output checks/Makefile.
3106 * checks/get_them: Have the dnl header of each test more
3107 recognizable by next-error, also use a better message.
3109 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3111 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3112 And use that only if __GNUC__ since we're using it's GCC-specific
3113 semantics that tell the compiler the associated function doesn't
3114 return.
3116 * builtin.c (substitute): Don't use character as an array index.
3117 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3118 warnings with gcc -W -Wall on systems with qsort prototype.
3119 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3120 from gcc -W -Wall.
3122 * eval.c (most functions): Add parentheses to assignments used
3123 as truth values go avoid warnings from gcc -Wall.
3125 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3126 any functions that don't need external scope.
3128 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3129 (many functions and arrays): Declare `const'.
3131 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3133 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3134 removing the declaration from m4.h. Also rename false to FALSE
3135 and true to TRUE.
3137 * lib/Makefile.in (Makefile): New goal.
3139 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3140 so heavily loaded. It gets more easily overridable, calling make.
3141 Reported by Jim Meyering.
3143 * Makefile.in (dist): Get .fname from the current directory name,
3144 instead of from version.h. I need updating many files manually,
3145 when the version changes, version.h is just one of them.
3147 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3149 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3150 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3151 Reported by Tom McConnell.
3153 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3155 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3156 39.cleardiv, which were describing missing or spurious newlines.
3157 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3158 do not depend on machine word size, `/bin/false' implementation,
3159 or `wc' output format. `make check' is more dependable, now.
3161 * checks/check_them: Summarize the failed tests by listing their
3162 name, at end. If none, issue `All checks successful'. Output
3163 `Checking' instead of `Input file:'.
3165 * checks/get_them, checks/check_them: Reindented.
3167 * Makefile.in (dist): chmod a+r before making the tar file.
3169 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3171 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3173 * input.c (next_token): Reinitialize token_buttom just after using
3174 it as a watermark with obstack_free. Or else, a future token, big
3175 enough for triggering reallocation of the obstack chunk, could
3176 void the initialized value of token_buttom, later causing panic in
3177 obstack_free. Rename token_buttom to token_bottom everywhere.
3179 * m4.h: Before declaring errno, first include <errno.h> and
3180 ensure that it does not define errno.
3181 Reported by Richard Stallman.
3183 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3185 * builtin.c: Define and use DECLARE macro for builtins.
3187 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3188 argument, this is a common idiom for introducing long comments.
3190 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3191 arguments. The last argument was silently ignored.
3193 * m4.c (cmd_error): Add a missing semicolon before va_end().
3195 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3197 * Makefile.in: Now handle protoized sources. Define and use U.
3198 Compile and use ansi2knr with old compilers. Update DISTFILES.
3199 Add `aclocal.m4' to `configure' dependencies.
3200 * ansi2knr.c: New, from Ghostscript distribution.
3201 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3202 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3203 * aclocal.m4: New, provide FP_PROTOTYPES.
3204 * m4.h: Conditionnaly protoized through Args, save for varags.
3205 * builtin.c: Protoized. Then:
3206 Include <sys/types.h> if size_t is not defined, before "regex.h".
3207 (m4_ifelse): Fetch built-in name properly for diagnostic.
3208 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
3209 (m4_regexp): Add const to `msg' declaration.
3210 (m4_patsubst): Add const to `msg' declaration.
3211 * debug.c: Protoized, save for varargs.
3212 * eval.c: Protoized.
3213 * format.c: Protoized.
3214 * input.c: Protoized.
3215 * m4.c: Protoized, save for varargs. Then:
3216 (xfree): Accept void * instead of char *.
3217 (xmalloc): Return void * instead of char *.
3218 (xrealloc): Accept and return void * instead of char *.
3219 * macro.c: Protoized.
3220 * output.c: Protoized.
3221 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3222 * symtab.c: Protoized.
3224 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3226 * m4.texinfo: Remove directory from diagnostics in 30.include,
3227 51.eval, 56.errprint and 57.m4exit tests.
3229 * m4.h: Remove declarations for int or void system functions, they
3230 cause more conflicting trouble than they make good.
3232 * configure.in: Avoid configuration header file. Add some tests.
3233 * m4.h: Remove #include "config.h".
3234 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3235 Then, rewritten for better compliance with GNU standards.
3237 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3239 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3240 because of a misplaced #endif.
3242 * Many *.[hc] files: Correct intra-line spacing here and there,
3243 according to GNU indent 1.6 advice.
3245 * configure.in: New, using Autoconf 1.2.
3246 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
3247 * Delete old configure.in, configure, etc/configure.in,
3248 etc/configure, lib/configure.in, lib/configure and config/*.
3249 Reported by Jason Merrill.

3252 Reported by Jason Merrill.
3254 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
3255 etc/nextvers.sh. Release numbers will be edited `by hand'.
3256 * version.h: De-automatize, force value in.
3258 * m4.c: Changes in order to use a newer getopt.h.
3259 Reported by David MacKenzie.
3261 * checks/: New name for examples/.
3262 * checks/get_them: New location for etc/get_examples.
3263 * checks/check_them: New location for etc/check_examples.
3264 * Makefile.in, checks/get_them, checks/check_them: Adjust.
3265 * lib/vfprintf.c: New location for etc/vfprintf.c.
3266 * Delete empty etc/.
3267 * examples/: New name for test/.
3269 Tue Mar 10 00:29:46 1992 Francois Pinard (pinard at icule)
3271 * Makefile.in (check): Add m4 as dependency.
3273 * m4.c: Accept --no-warnings instead of --no_warnings, and
3274 --no-gnu-extensions instead of --no_gnu_extensions. Make the
3275 usage message more informative.
3276 Reported by David MacKenzie.

3292 Reported by Richard Stallman.
3294 * config/hmake-unicos, config/s-unicos.h: New files.
3295 Reported by Hal Peterson.
3297 * eval.c (exp_term): Have N^0 return 1.
3298 Reported by Michael Fetterman.
3300 * eval.c, input.c, m4.h: Remove last comma in enums.
3301 Reported by Mike Lijewski.
3303 * Transfer of maintenance duties from Rene' to Franc,ois.
3304 \f

3308 reports and feedback.
3310 * Uses GNU configure, taken from the gdb distribution.
3312 * Uses GNU getopt(), with long option names.
3314 * The -Q/+quiet option is added, which suppresses warnings about
3315 missing or superflous arguments to built-in macros.
3317 * Added default options via the M4OPTS environment variable.
3319 * The built-in format can now be configured to use sprintf as
3320 the formatting engine, for systems without [efg]cvt(3).

3330 Francois Pinard and Roland H. Pesch for providing me with reports.
3332 * The builtins incr and decr are now implemented without use of
3333 eval.
3335 * The builtin indir is added, to allow for indirect macro calls
3336 (allows use of "illegal" macro names).
3338 * The debugging and tracing facilities has been enhanced
3339 considerably. See the manual for details.
3341 * The -tMACRO option is added, marks MACRO for tracing as soon
3342 as it is defined.

3359 * A bug in the multi-character quoting code is fixed.
3361 * Several typos in the manual has been corrected. More probably
3362 persist.
3364 * The m4.info file is now installed along with the program.
3365 \f
