2014 2005-10-17 Gary V. Vaughan <gary@gnu.org>
2016 * doc/m4.info: Generated files are not kept in the repository.
2018 2005-05-01 Gary V. Vaughan <gary@gnu.org>
2020 The FSF are moving offices today. Changed their contact address
2021 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
2022 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
2024 Also, some of the files here were never updated from the previous
2025 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
2026 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
2028 2005-03-31 Mike Frysinger <vapier@gentoo.org>

2036 2005-03-31 Gary V. Vaughan <gary@gnu.org>
2038 Changes needed to automate the release process for 1.4.3:
2040 * Makefile.in (dist): Make .tar.bz2 tarball too.
2041 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
2042 (cvs-news): Look 1 line further down for NEWS release number.
2043 (cvs-dist): We don't use automake, so make dist is fine.
2044 Remove double . before suffixes.
2045 (cvs-release): Don't mention manual.html.
2046 (fetch): Get latest gendocs files.
2047 (web-manual): Rewritten to use gendoc for multiformat manuals.
2048 * doc/gendocs.sh: Don't save an old version in m4 CVS!
2049 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
2050 preserving, but case insensitive, so generating html docs per node
2051 clashes between Index.html, the node file, and index.html, the
2052 top-level of the document tree...
2053 (Index macro): ...so renamed to this. Changed all references.
2055 2005-03-31 Gary V. Vaughan <gary@gnu.org> (tiny change)

2072 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)
2074 * doc/m4.texinfo (Patsubst): Re-add trailing space required by
2075 checks/47.patsubst, with a redundant @comment to prevent emacs
2076 from removing it accidentally again.
2077 * checks/get-them: Allow for trailing spaces tucked behind
2078 @comment marks.
2080 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

2107 recognition macros.
2108 * src/freeze.c (produce_frozen_state): Use \n line-endings even
2109 on Windows, so that the frozen file reader will work.
2110 Reported by Josef T. Burger.
2112 * src/m4.c (main): Modernise the --version output.
2114 2005-02-03 Gary V. Vaughan <gary@gnu.org>
2116 Modernise the configury a little to prevent spurious errors from
2117 Autoconf-2.59's autoreconf:
2119 * config.h.in: Renamed to...
2120 * config-h.in: ...this to better support DOS 8.3 file systems.
2121 * acconfig.h: Removed.
2122 * configure.in: Renamed to...
2123 * configure.ac: ...this, and AC_DEFINE used to declare config.h
2124 entry comments. Slight reorganisation and reformatting.
2125 * aclocal.m4: Use third argument to AC_DEFINE to declare config.h
2126 entry comments.
2127 (AC_INIT): Use a modern 3 argument call.

2130 s/PRODUCT/PACKAGE/g.
2131 * Makefile.in (DISTFILES): Removed acconfig.h, configure.in,
2132 config.h.in. Added configure.ac, config-h.in.
2133 (stamp-h.in): Removed acconfig.h from dependencies.
2134 (configure): Depends on configure.ac, not configure.in.
2135 * doc/Makefile.in (stamp-vti): Ditto.
2136 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for
2137 difference between PRODUCT="m4" and PACKAGE="GNU M4".
2138 * configure: Regenerated.
2140 2005-02-03 Noah Misch <noah@cs.caltech.edu>
2142 * src/output.c (mkstemp): Make non-static, and build regardless of
2143 HAVE_TMPFILE; src/builtin.c also needs this replacement.
2144 * NEWS: Update.
2146 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
2148 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
2149 changes from your editor buffer first.
2151 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.

2153 * NEWS: Updated.
2155 2004-09-09 Andreas Schwab <schwab@suse.de>

2172 * News: Describe 1.4.2's changes.
2174 * src/m4.c (reference_error): Preserve errno, since M4ERROR
2175 relies on this.
2176 * src/builtin.c (m4_esyscmd): Clear errno before calling popen.
2177 (m4_maketemp): Clear errno before calling mkstemp.
2178 * src/path.c (path_search): Don't let "free" trash errno when
2179 returning NULL.
2180 * src/output.c (insert_file): Don't assume errno has a valid
2181 value simply because fread returns zero. This fixes a
2182 portability bug reported by Marion Hakanson in
2183 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
2185 2004-06-09 Gary V. Vaughan <gary@gnu.org>

2200 to pacify Texinfo 4.7.
2201 * doc/Makefile.in (info): Remove info-1, info-2, info-3.
2203 * src/m4.h, src/debug.c: Use #ifdef __STDC__, not #if __STDC__, to
2204 pacify Sun C compilers.
2206 2003-09-28 Akim Demaille <akim@epita.fr>
2208 * src/symtab.c (lookup_symbol): Fix an uninitialized-variable

2226 2001-02-01 Matt Kraai <kraai@debian.org>
2228 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
2229 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
2230 empty file rather than to a nonexistent file. This closes a common
2231 security hole.
2232 * src/builtin.c (m4_maketemp): Implement the above, by using
2233 mkstemp rather than mktemp. (trivial change)
2235 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
2237 * src/builtin.c (expand_ranges): Added break after trailing dash.
2238 This caused misbehaviors on some systems.

2249 be opened, return immediately after producing the error message.
2250 Reported by Andreas Schwab.
2252 * configure.in: Check for const only after having found possible
2253 ANSIfying compiler flags, this is of no use to check it before.
2254 Reported by Alexander Lehmann.
2256 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
2258 * src/macro.c (collect_arguments): Cast obstack arguments to
2259 (voidstar), so avoiding compiler warnings.
2260 Reported by Joseph E. Sacco.
2262 * src/freeze.c (produce_frozen_state): Cast printed lengths to
2263 (int) so they correspond to %d format items.
2264 Reported by Joseph E. Sacco.
2266 * src/m4.c (main): Cast the argument to xfree to (voidstar).
2267 * src/symtab.c (free_symbol): Idem.
2268 Reported by Karl Vogel.
2270 Mon Oct 31 02:11:19 1994 Francois Pinard (pinard@icule)

2279 Sun Oct 30 08:13:03 1994 Francois Pinard (pinard@icule)
2281 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
2282 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
2283 defines __STDC__ to 0, for indicating it is *not* ANSI!
2284 Reported by Kaveh R. Ghazi.
2286 * configure.in: Added obsolescent tests for AIX and Minix.
2288 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
2289 which texclean does not exist anymore.
2290 Reported by Eric Backus, Jim Meyering, John David Anglin and
2291 Joseph E. Sacco.

2298 * src/ansi2knr.c: New version, sent by Peter Deutsch.
2299 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
2300 ANSI2KNR, depending on the fact the compiler is ANSI or not.
2301 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
2302 Remove the sed filter after ansi2knr for debug.c. Use $O instead
2303 of $U, put underline in extensions rather than in basenames. Use
2304 implicit rules, now that regularity makes this possible.
2305 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
2306 of ansi2knr whenever it is needed.
2307 * configure.in: Adjusted for correct STACKOVF substitution.
2308 * src/debug.c (trace_format): When not __STDC__, use (...) as a
2309 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
2310 Reported by David MacKenzie.
2312 * Makefile.in: Remove binprefix. Use transform_name instead.
2313 Reported by David MacKenzie.
2315 * doc/Makefile.in: Create version.texi, use it, clean it.
2316 Reported by Jim Meyering.
2318 Fri Oct 28 20:33:55 1994 Francois Pinard (pinard@icule)
2320 * Makefile.in (all, install, uninstall): Depend on Makefile.
2322 * Makefile.in: For actions invoking $(MAKE) from within compound
2323 sh statements, exit non-zero if the sub-make fails. Otherwise,
2324 the top-level make may exit successfully when it should fail.
2325 Reported by Jim Kingdon.
2327 * {,/*}Makefile.in: Use && after all cd, in case they fail.
2329 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
2330 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
2331 * configure.in: Substitute PRODUCT and VERSION.
2333 * {,*/}Makefile.in (dist): Always try a hard link before a copy.
2335 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
2337 * Makefile.in (mostlyclean-local): Do not remove *~.
2338 * */Makefile.in (mostlyclean): Idem.
2339 Reported by Robert E. Brown and Richard Stallman.
2341 Sun Oct 9 08:30:13 1994 Francois Pinard (pinard@icule)

2345 Sun Oct 2 16:48:10 1994 Francois Pinard (pinard@icule)
2347 * configure.in: Use AC_ARG_PROGRAM.
2348 * aclocal.m4 (fp_C_PROTOTYPES): Substitute @kr@ by kr or empty.
2349 Reported by David MacKenzie.
2351 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)
2353 * configure.in: Do not add -O to CFLAGS for GNU C, now that
2354 configure does it automatically.
2355 Reported by Jim Meyering.
2357 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
2359 * src/stackovf.c: Declare the handler_t typedef earlier in the
2360 code, use it for stackovf_handler.
2361 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
2362 casting sigsegv_handler.
2363 Reported by Robert Bernstein.
2365 * src/m4.c (main): Initialize program_name to argv[0] without
2366 basename'ing it.
2367 Reported by Karl Berry.
2369 Sun Sep 18 11:42:50 1994 Francois Pinard (pinard@icule)
2371 * src/Makefile.in (TAGS): Include a ../lib/TAGS reference.
2372 Reported by Karl Berry.

2376 * lib/Makefile.in (mostlyclean): Added.
2377 (TAGS): Make in $(srcdir).
2379 * configure.in: Use `choke me' in test, like everywhere!

2382 unreacheable and useless.
2384 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
2386 * lib/Makefile.in (DISTFILES): Distribute TAGS.
2387 (distclean): Do not remove TAGS.
2388 (realclean): Remove it.
2389 * Makefile.in: Make TAGS in lib also, not just in src.
2390 Reported by Karl Berry.
2392 * Makefile.in (distclean, realclean): Instead of recursively
2393 calling $(MAKE) for the -local part, allow parallel execution of
2394 -recursive and -local, only delay the removal of config.status,
2395 which is repeated in both goals.
2396 \f
2397 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
2399 Release 1.3.
2400 * Makefile.in: Group all *clean-recursive goals in one, using sed
2401 to remove `-recursive' while calling make recursively. Also, use
2402 a subshell for each recursive $(MAKE).
2403 Reported by Jim Meyering.
2405 * src/m4.h (memcpy): Define with bcopy for BSD systems.
2406 Reported by Kaveh R. Ghazi.
2408 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2409 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
2410 specify it.
2412 * configure.in: Use date instead of touch for stamp-h.
2413 * Makefile.in (stamp-h.in): Idem.
2415 * Makefile.in (distclean, realclean): Force serial execution of
2416 both goals, in case parallel makes are being used.
2417 Reported by Jim Meyering.
2419 * src/Makefile.in (DISTFILES): Distribute TAGS.
2420 (distclean): Do not remove TAGS.
2421 (realclean): Remove it.
2422 Reported by Karl Berry.

2429 Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
2431 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
2432 ./install.sh will not be correctly referred to in sub-Makefiles.
2433 Reported by John David Anglin.
2435 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
2436 Reported by Eric Backus.
2438 * Makefile.in, checks/Makefile.in, doc/Makefile.in,
2439 examples/Makefile.in, lib/Makefile.in, src/Makefile.in: Limit
2440 config.status into remaking this directory's Makefile only.
2441 * Makefile.in (stamp-h): Do not check nor touch stamp-h.

2443 Reported by Jim Meyering.
2445 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)
2447 * configure.in: Correct stack overflow detection logic, taking
2448 care of systems having only incomplete implementations (like for
2449 Pyramid 9820 OSx 5.0d).
2450 Reported by Kaveh R. Ghazi.
2452 * src/Makefile.in (TAGS): Remote -t from etags call.
2454 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)
2456 * lib/Makefile.in (install): Depend on all.
2458 Wed Aug 31 11:17:21 1994 Francois Pinard (pinard@icule)
2460 * examples/Makefile.in (mostlyclean): Do not depend on texclean.
2461 Reported by Jim Meyering and John David Anglin.
2463 * Makefile.in (distclean-local): Delete config.log.
2464 Reported by Jim Meyering.
2466 Solidify frozen files with respect to -P:
2467 * src/m4.c: Have -P set prefix_all_buitins variable instead of
2468 calling a function by that name. Declare the variable.
2469 * src/m4.h: Adjust declaration for prefix_all_buitins.
2470 * src/builtin.c (builtin_init): Merge in functionality from
2471 previous prefix_all_buitins function, while making entries in the
2472 symbol table, but not modifying the builtin description itself.
2474 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2475 because *many* compilers do not accept an empty `default:'.
2476 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2477 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2479 * configure.in: Use AC_TYPE_SIGNAL.
2480 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
2481 Reported by Robert Bernstein.
2483 * checks/Makefile.in (check): Modify PATH so check-them will find
2484 m4 in the src directory.
2485 * Makefile.in (check): Don't.
2486 Reported by Akiko Matsushita and Jim Meyering.
2488 * src/output.c (make_room_for, output_character_helper): New
2489 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
2490 a per buffer MAXIMUM_BUFFER_SIZE.
2492 * src/output.c (output_text): New function, for optimizing the
2493 output of strings of characters. Use it.
2495 Tue Aug 30 01:44:29 1994 Francois Pinard (pinard@icule)
2497 * doc, src: New directories reorganizing the distribution.
2498 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
2499 files.
2500 * Makefile.in: Adjusted.
2501 * configure.in: Configure new Makefiles.
2503 * m4.h: Declare STRING typedef. Use it for comment and quote
2504 strings, adjusting all references. (This is the rudiments of a
2505 beginning for the eventual withdrawal of NUL terminated strings.)
2506 * output.c (shipout_text): Accept a length parameter, and use it.

2511 * m4.h: Include <unistd.h> if it exists.
2512 * stackovf.c: Don't.
2514 Clean up for current_diversion variable:
2515 * output.c: Move current_diversion from builtin.c.
2516 * m4.h: Declare current_diversion so builtin.c can access it.
2517 * output.c (output_init, make_diversion): Initialize or update
2518 current_diversion.
2519 * builtin.c (builtin_init, m4_divert): Leave current_diversion

2522 Remove limit on number of diversions:
2523 * output.c: Replace ndiversion by diversions, declare it.
2524 (output_init): Allocate only diversion 0.
2525 (make_diversion): Allocate new diversions as needed.
2526 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
2527 * m4.c: Still accept -N, but do nothing with it.
2528 Reported by David MacKenzie.
2530 Freeze diversions:
2531 * output.c (freeze_diversions): New function.
2532 * m4.h: Declare freeze_diversions.
2533 * freeze.c: Document frozen file format, revise it, call
2534 freeze_diversions to add diversions to frozen format, and code to
2535 reload them properly.
2536 * m4.c: Do not undivert automatically at end when status being
2537 frozen. Do not call builtin_init when reloading frozen state.
2539 Speed up diversion processing:
2540 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2541 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2542 structure and variables, cached variables out of output_diversion,
2543 reallocate_diversion_for and OUTPUT_CHARACTER.
2544 (shipout_text, make_diversion, insert_diversion): Adapted to new
2545 structures.
2546 (insert_file): Use better buffering.
2547 Reported by David MacKenzie.
2549 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
2551 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
2552 dist works from another build directory.
2554 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2556 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2557 constant HASHMAX, for -H option to work better.
2559 * builtin.c (DECLARE): Simplify by using _ ().
2561 * freeze.c: New file.
2562 * Makefile.in: Compile it, distribute it.
2563 * m4.c: Recognize, document and process --freeze-state (-F) and
2564 --reload-state (-R) options. Pass a true flag to builtin_init
2565 only if no reloading some state.

2574 specifier.
2576 * configure.in: Implement --with-dmalloc.
2577 * acconfig.h: Document WITH_DMALLOC.

2580 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2582 * m4.c (long_options): Use "error-output", the dash was missing.
2583 Reported by Akiko Matsushita.
2585 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2587 * m4.h: Include <sys/types.h>.
2588 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2589 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2590 int.
2591 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2592 as size_t, not int.
2593 * builtin.c (dump_args): Declare len as size_t, not int.
2595 * debug.c: Prototype the forward declaration of debug_set_file.
2597 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2598 shadowing of this variable.
2599 * output.c (insert_diversion): Idem.
2601 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2602 (input_init): Duplicate default quote and comment strings.

2606 Duplicate even default comment strings.
2608 * configure.in: Updated for Autoconf 2.0.
2609 * Makefile.in (distclean-local): Also delete config.cache.
2611 * m4.c (usage): Reorganize the --help output by topic. Include a
2612 description for debugging flags.
2614 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2616 * configure.in: If sigaction is available and SA_ONSTACK defined,
2617 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2618 defined, use sigvec. Else don't compile stackovf.c.
2619 * stackovf.c (setup_stackovf_trap): Idem.
2620 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2621 and Simon Leinen.
2623 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2625 * m4.c (usage): Replace printf par fputs.
2626 \f
2627 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2629 * Release 1.2
2631 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2633 * configure.in: Check for sigaction and sigvec. Add a new delayed
2634 check for RLIMIT_STACK, combine in the checking for getrlimit.
2635 All those things are not universally available.
2636 * stackovf.c: Split setting up the trap handler and catching
2637 signals, for better taking care of various configure outcomes.
2638 * examples/stackovf.sh: Correct a typo.
2639 Reported by Eric Backus, Jim Avera and Jim Meyering.
2641 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2643 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2645 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2647 * Makefile.in: Modify so parallel make will not try making
2648 lib/libm4.a twice simultaneously.
2649 Reported by Jim Meyering.
2651 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2653 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2654 error message, for when no code possibility exists. Even if this
2655 line is completely #ifdef'ed out, it brings a syntax error.
2656 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2658 * Makefile.in (install): Have install depend on all too, for lib
2659 to be remade as needed.
2661 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2662 providing ulimit, instead of using only ksh.
2663 Reported by Jim Avera and Joseph E. Sacco.
2665 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2667 * Makefile.in (check): Have it depend on all instead of m4. In
2668 this way, a change in lib will be detected and processed.
2670 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2671 instead of using sscanf which stops as soon as there is a
2672 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2673 and divert(1xyzzy) were all accepted without any warning or error
2674 messages.
2675 * m4.h: Declare strtol as long if not including stdlib.h.
2676 * configure.in: Check for limits.h, and replace strtol if missing.
2677 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2678 * lib/strtol.c: New file, from elsewhere.
2679 Reported by Andreas Schwab.
2681 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2683 * macro.c (expand_macro): Cast value to (boolean) prior to
2684 assigning it to traced.
2685 Reported by Tom McConnell.
2687 * Makefile.in (m4): Always make all in lib first.
2688 Reported by Jim Meyering.
2690 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2692 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2693 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2694 handlers), and a default error message if the fault address is not
2695 available (when neither siginfo.h nor BSD sigcontext are supported).
2696 * configure.in: Changes for stackovf.h: Check for sigcontext,
2697 sigaction, sigstack, and define rlim_t as int if necessary.
2698 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2699 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2700 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2702 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2704 * configure.in: Use AC_SET_MAKE.
2705 * Makefile.in: Use @SET_MAKE@.
2706 Reported by Jim Meyering.
2708 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2709 Reported by Ian Taylor.
2711 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2713 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2714 because siginfo.h is unrelated to standard headers, and siginfo.h
2715 is already checked for.
2716 Reported by Joseph E. Sacco.
2718 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2719 PROTOTYPES.
2720 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2721 AC_PROTOTYPES.
2723 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2725 * builtin.c (substitute): Use \& to represent this part of the
2726 string which was matched by the whole regexp, instead of
2727 representing the whole string. Any usage of \0 issues a warning
2728 and acts like \&, it will disappear in some subsequent release.
2730 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2732 * m4.c: Complete prototype for forwarded declaration of usage.
2734 * input.c (init_macro_token): Correct own reference in error
2735 message. Previous name get_macro_func was referred to instead.
2736 (next_char): Correct own reference in error message. Previous
2737 name advance_input was referred to instead.
2739 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2740 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2741 and_term, not_term, logical_not_term, cmp_term, shift_term,
2742 add_term, mult_term, exp_term, unary_term, simple_term): Add
2743 prototype to forwarded declarations. Declare parameter v1 as
2744 eval_t * instead of int *. Same for local variable v2 in dyadic
2745 functions. Same for result in exp_term.
2746 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2747 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2748 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2749 (shipout_int): Cast first argument of ntoa to eval_t.
2750 Reported by Thorsten Ohl.
2752 * macro.c: Complete the prototypes of forwarded expand_macro and
2753 expand_token.
2754 Reported by Thorsten Ohl.
2756 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2757 The Ultrix 3.1 compiler cannot do much with void pointers.
2759 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2760 * m4.c (xfree): Replace void * by voidstar.
2761 Reported by Tom McConnell.
2763 * ansi2knr.1: New, from elsewhere.
2764 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2766 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2767 stamp-h does not exist yet. This avoids running it a second time
2768 just after the initial ./configure.
2769 Reported by David MacKenzie and Tom McConnell.
2771 * m4.h: Replace the enum debug_info declaration with a series of
2772 #define's. The Ultrix 3.1 compiler would otherwise need casting
2773 (int) to most references, when used in expressions.
2774 Reported by Tom McConnell.
2776 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2778 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2779 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2780 calls the compiler. Previously, FP_PROTOTYPES was only calling
2781 the preprocessor; by not being subject to CFLAGS, this was
2782 discouraging those flags asking for ANSI compilation.
2783 * acconfig.h: Document HAVE_PROTOTYPES.
2784 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2785 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2786 Reported by Eric Backus.
2788 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2789 from the environment. Default CFLAGS to -g if not set.
2790 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2791 * lib/Makefile.in: Have CFLAGS substituted from configure.
2792 Reported by Eric Backus and Tom McConnell.
2794 * configure.in: m4_undefine changeword before using AC_ENABLE.
2796 * m4.h: Declare prototypes for error (for ANSI compilers only),
2797 prefix_all_builtins and reference_error.
2798 Reported by Tom McConnell.
2800 * input.c (set_word_regexp): Do not try to initialize the array
2801 test from a string, this does not work with non-ANSI compilers.
2802 Reported by Eric Backus.
2804 * Makefile.in (dist): Clean examples/ before saving it.
2805 (distclean-local): Also remove stamp-h.
2806 Reported by Eric Backus.
2808 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2809 non ANSI compilers.
2810 Reported by Tom McConnell.
2812 * checks/Makefile.in (clean): Depends on mostlyclean.
2813 (mostlyclean): New goal.
2815 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2817 * Makefile.in (DISTFILES): Distribute install.sh.
2818 * install.sh: New file, copied from elsewhere.
2819 Reported by Assar Westerlund and Kaveh R. Ghazi.
2821 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2823 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2824 * acconfig.h: Explain ENABLE_CHANGEWORD.
2826 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2827 from code provided by Pete Chown]
2828 * m4.h: Add original_text field to u_t variant of union u.
2829 Declare TOKEN_DATA_FUNC macro.
2830 * builtin.c: Declare changeword.
2831 (m4_changeword): New function.
2832 * input.c: Include "regex.h", define variables with word regexps.
2833 (input_init): Initialize the word regexp.
2834 (set_word_regexp): New.
2835 (next_token): Declare local variables, use the previous code if
2836 default_word_regexp is true. Else, match using a new code. Save
2837 the original text.
2838 * macro.c (expand_token): Ship out original text if not a macro
2839 name.
2840 Reported by Krste Asanovic and Pete Chown.
2842 [These modifs all depend upon ENABLE_CHANGEWORD]
2843 * m4.h: Declare external user_word_regexp.
2844 * m4.c: Declare user_word_regexp, and initialize it from
2845 --word-regexp or -W, or NULL if not specified.
2846 * input.c: Use user_word_regexp if specified, instead of
2847 DEFAULT_WORD_REGEXP.
2849 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2850 agree with it.
2852 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2853 * checks/Makefile.in: Empty the suffix list.
2854 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2856 * m4.c: Declare nesting_limit and initialize it to 250.
2857 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2858 value.
2859 * m4.h: Declare nesting_limit as external.
2860 * macro.c (expand_macro): Stop execution whenever nesting limit
2861 is exceeded.
2862 Reported by Bengt Mertensson.
2864 * eval.c (evaluate): Diagnose excess characters in eval input.
2865 Things like `eval(08)' used to return 0 with no diagnostic.
2867 * m4.h: Capitalize first letter of all macro arguments in
2868 definitions.
2870 * m4.c: Declare warning_status, initialize it to 0. Add new
2871 option -E, or --fatal-warnings, which sets warning_status to
2872 EXIT_FAILURE instead.
2873 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2874 EXIT_FAILURE if not otherwise done by header files.
2875 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2876 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2877 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2878 argument of all M4ERROR calls.
2879 Reported by Noah Friedman.
2881 * examples/incl-test.m4: Renamed from incl_test.m4.
2882 * examples/include.m4: Include incl-test.m4 instead of
2883 incl_test.m4.
2884 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2886 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2888 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2889 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2890 also tested it on a Sun Sparc workstation running SunOS 4.x.
2892 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2893 49.format check, abusing a `union values' argument with sprintf
2894 without selecting the proper field. Now, save the formatting type
2895 first, delaying the fetch of the corresponding argument.
2896 Reported by Joseph E. Sacco and Tom Quinn.
2898 * format.c (format): Remove const from char *fmt declaration when
2899 not HAVE_EFGCVT, because a NUL may be forced into it.
2901 * m4.h: Declare atof() when not STDC_HEADERS.
2902 Reported by Joseph E. Sacco.
2904 * Regenerate configure using Autoconf 1.11, this corrects a
2905 problem about an incorrect cpp seting on NeXT 3.1.
2906 Reported by Alexander Lehmann.
2908 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2910 * m4.h (_): Change argument from `x' to `Args'.
2912 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2914 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2915 bringing more evil than good on a few systems.
2916 Reported by Greg A. Woods.
2918 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2920 * m4.h: Rename Args() to _().
2921 * m4.h: Remove extern specifier from all function declarations.
2923 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2925 * stackovf.c: New file implementing stack-overflow detection.
2926 * configure.in: Check for getrlimit, sigaction. If all of
2927 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2928 substitute ${U}stackovf.o for STACKOVF.
2929 * acconfig.h: Declare USE_STACKOVF.
2930 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2931 * m4.h: Declare setup_stackovf_trap().
2932 * m4.c: Call setup_stackovf_trap().
2933 * tests/stackovf_test.sh: New file.
2935 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2937 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2939 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2941 Sun Jan 30 14:24:19 1994 (pinard at icule)
2943 * m4.h: Remove definition of volatile, not used anymore.
2944 Reported by Jim Meyering and Joseph E. Sacco.
2946 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2947 of `if ... else /* nothing */' for if macros.
2948 Reported by Jim Meyering.
2950 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2951 warning from gcc about `repl' possibly used before defined.
2952 Reported by Jim Meyering.
2954 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2955 Reported by Jim Meyering.
2957 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2959 * m4.h: Move the conditional definition of volatile after the
2960 inclusion of system files, because they may define it first.
2962 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2964 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2965 get around a problem with Alpha make seeing a syntax error, there.
2966 Reported by Vern Paxson.
2968 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2970 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2971 Reported by Richard Stallman.
2973 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2975 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2976 instead of AC_HAVE_FUNCS.
2977 Reported by Noah Friedman.
2979 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2981 * m4.c: Initialize show_help and show_version to zero.
2983 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2984 Use them in exit() and usage() calls.
2986 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2988 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2989 syserr() macro. Delete errref, add reference_error and M4ERROR.
2990 * m4.c: Replace errref, which was returning an input reference
2991 string, with reference_error, which prints it on standard error.
2992 * builtin.c, output.c: Use errno as second parameter to error,
2993 instead of using syserr() with %s.
2994 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2995 Doing so, the program name appears after the input reference
2996 instead of before, which eases M-x next-error processing.
2998 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
3000 * checks/get-them: Escape braces with backslashes in patterns,
3001 because HPUX-9.01 awk needs this.
3002 Reported by Jim Meyering.
3004 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
3006 * builtin.c: Declare "FILE *popen ();".

3009 macros, replace error_message_prefix() declaration by errref()'s.
3010 Declare xrealloc, for use in errref().
3011 * m4.c: Delete error_message_prefix() function, add errref().
3012 * *.c: Use error() systematically in place of all error macros,
3013 now that error() flushes stdout first. Make needed adjustments.
3015 * m4.h: Remove const in sys_errlist[] declaration, it creates
3016 conflicts on SGI and Alpha.
3017 Reported by Kaveh R. Ghazi.
3019 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

3035 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
3037 * input.c (input_init): Initialize quote and comment strings
3038 explicitely instead of calling set_quotes and set_comment: by
3039 doing so, we ensure we do not free uninitialized variables.
3041 * checks/check-them: Reverse arguments to both diff, so the
3042 expected is on the left and the obtained on the right.
3044 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

3048 routines, add error_message_prefix routine.
3049 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
3050 warning with WARNING*, fatal with FATAL* and internal_error with
3051 INTERNAL_ERROR*.
3052 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
3053 this is not needed anymore.

3068 (trace_format): Use stdarg instead of varargs if __STDC__.
3070 * configure.in: Remove checks for vfprintf and _doprnt. These
3071 implementations use varargs tricks which are not portable enough.

3093 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
3094 Reported by Joel Sherrill.
3096 * builtin.c (prefix_all_builtins): Instead of the table size, use
3097 the null entry at end for stopping the loop. It was overwritten.
3098 Reported by Andreas Schwab and Jim Meyering.
3100 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
3101 Reported by Kaveh R. Ghazi.

3127 * Release 1.1
3129 * configure.in: Do not copy check files in the build hierarchy.

3291 ensure 777 mode for directories, so older tar's will restore file
3292 modes properly.
3294 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
3296 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),

3339 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
3341 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
3342 might well use CFLAGS is s/he needs it.
3344 * Makefile.in: Allow installation of info files from a separate

3357 * lib/alloca.c: New, from elsewhere.
3358 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3360 * m4.h: Do not define index/rindex if already defined. If
3361 FALSE/TRUE are already defined, do not redefine them, but merely
3362 define boolean typedef to int.
3364 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3365 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3366 because some C compilers do not like connectives with #ifdef.
3367 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3368 __GNUC__ and once for __STDC__.
3369 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3371 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3372 Makefile dependencies. Without it, make keeps destroying and
3373 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3375 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3376 to diversion/DIVERSION, this was a spelling error.
3378 * m4.c: Declare version[], remove #include "version.h".
3379 * version.h: Deleted.
3380 * Makefile.in: Remove references to version.h.
3382 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3383 production, by using a simpler and more robust algorithm. This
3384 solves the problem of synclines sometimes written in the middle of
3385 an output line. Delete sync_line() and output_lines variable.
3386 * m4.h: Remove sync_line prototype and output_lines declaration.
3387 * input.c (next_char), output.c (shipout_text): Remove references
3388 to output_lines.
3389 * input.c (push_file, pop_file): Merely put the value -1 in
3390 output_current_line instead of calling sync_line, for delaying a
3391 single `#line NUM FILE' before next output line. Do not test
3392 for sync_output, because this is unnecessary clutter.
3393 * output.c (make_divertion, insert_divertion): Idem.
3394 * input.c: Rename must_advance_line to start_of_input_line, for
3395 consistency.
3397 * debug.c (trace_header): Select a new debug line format, which
3398 better complies with GNU standards for formatting error messages.
3399 With option `-dfl', M-x next-error might be used on the output.
3400 * m4.c (vmesg): Adjust format of error output to GNU standards.
3401 * m4.texinfo: Adjust examples for `make check' to work.
3403 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3404 case for enum debug_info constants, which were all lower case.
3406 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3407 re_search_2.
3408 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3409 collected patches. I tried a few times using newer regex.[ch], it
3410 mysteriously stopped aborting with this one. Insecure feeling...
3411 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3413 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3415 * m4.c: Change `--no-warnings' to `--silent'.
3416 Reported by David MacKenzie.
3418 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3419 leave it off for now. See comment in m4.c for justification.
3420 Reported by David MacKenzie.
3422 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3423 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3425 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3427 * Makefile.in: Ensure recursive cleaning is done before local
3428 cleaning for all clean goals.
3430 * builtin.c (ntoa): Ensure the value is always interpreted as a
3431 signed quantity, whatever the radix is.
3433 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3435 * builtin.c, format.c, input.c: Split long lines.
3436 * m4.c: Use typedef macro_definition instead of struct
3437 macro_definition.
3438 * symtab.c: Use typedef symbol instead of struct symbol.
3440 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3442 * *.[ch]: Remove all trailing whitespace, in code and comments.
3444 * configure.in: Find some awk.
3445 * Makefile.in: Add $(AWK) to MDEFINES.
3446 * checks/Makefile.in: Transmit $(AWK) to get_them.
3447 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3448 awk script when switching files, because without this, mawk runs
3449 out of file descriptors.
3451 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3453 * Makefile.in (realclean): Delete m4.info*.
3454 Reported by Jim Meyering.
3456 * Makefile.in: Adjust and link with checks/Makefile.
3457 * checks/Makefile.in: New.
3458 * configure.in: Output checks/Makefile.
3460 * checks/get_them: Have the dnl header of each test more
3461 recognizable by next-error, also use a better message.
3463 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3465 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3466 And use that only if __GNUC__ since we're using it's GCC-specific
3467 semantics that tell the compiler the associated function doesn't
3468 return.
3470 * builtin.c (substitute): Don't use character as an array index.
3471 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3472 warnings with gcc -W -Wall on systems with qsort prototype.
3473 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3474 from gcc -W -Wall.
3476 * eval.c (most functions): Add parentheses to assignments used
3477 as truth values go avoid warnings from gcc -Wall.
3479 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3480 any functions that don't need external scope.
3482 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3483 (many functions and arrays): Declare `const'.
3485 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3487 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3488 removing the declaration from m4.h. Also rename false to FALSE
3489 and true to TRUE.
3491 * lib/Makefile.in (Makefile): New goal.
3493 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3494 so heavily loaded. It gets more easily overridable, calling make.
3495 Reported by Jim Meyering.
3497 * Makefile.in (dist): Get .fname from the current directory name,
3498 instead of from version.h. I need updating many files manually,
3499 when the version changes, version.h is just one of them.
3501 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3503 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3504 `boolean'. This tag conflicts with <sys/types.h> on SVR4.

3507 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3509 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3510 39.cleardiv, which were describing missing or spurious newlines.
3511 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3512 do not depend on machine word size, `/bin/false' implementation,
3513 or `wc' output format. `make check' is more dependable, now.
3515 * checks/check_them: Summarize the failed tests by listing their
3516 name, at end. If none, issue `All checks successful'. Output
3517 `Checking' instead of `Input file:'.
3519 * checks/get_them, checks/check_them: Reindented.
3521 * Makefile.in (dist): chmod a+r before making the tar file.
3523 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3525 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3527 * input.c (next_token): Reinitialize token_buttom just after using
3528 it as a watermark with obstack_free. Or else, a future token, big
3529 enough for triggering reallocation of the obstack chunk, could
3530 void the initialized value of token_buttom, later causing panic in
3531 obstack_free. Rename token_buttom to token_bottom everywhere.
3533 * m4.h: Before declaring errno, first include <errno.h> and
3534 ensure that it does not define errno.
3535 Reported by Richard Stallman.
3537 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3539 * builtin.c: Define and use DECLARE macro for builtins.
3541 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3542 argument, this is a common idiom for introducing long comments.
3544 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3545 arguments. The last argument was silently ignored.
3547 * m4.c (cmd_error): Add a missing semicolon before va_end().
3549 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3551 * Makefile.in: Now handle protoized sources. Define and use U.

3566 * eval.c: Protoized.
3567 * format.c: Protoized.
3568 * input.c: Protoized.

3572 (xrealloc): Accept and return void * instead of char *.
3573 * macro.c: Protoized.

3578 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3580 * m4.texinfo: Remove directory from diagnostics in 30.include,
3581 51.eval, 56.errprint and 57.m4exit tests.
3583 * m4.h: Remove declarations for int or void system functions, they
3584 cause more conflicting trouble than they make good.
