3 The regs_allocated field in a struct re_pattern_buffer refers
4 to the state of a particular re_registers struct when used in
5 successive matches using the same compiled pattern. Avoid a
6 SEGV in `renamesyms' resulting from using a new re_registers
7 with an existing re_pattern_buffer:
9 * modules/gnu.c (m4_pattern_buffer): Wrapper struct for associated
10 pattern buffer and registers.
11 (m4_regexp_search): New function to call re_regexp_search with
12 correctly matched pattern buffer and register instantiations.
13 (m4_regexp_compile): Return an m4_pattern_buffer. Adust all
16 2006-07-04 Gary V. Vaughan <gary@gnu.org>
18 * ltdl/m4/m4-getopt.m4 (M4_GETOPT): Update to take into account
19 changes to gnulib getopt.m4 since last build.
20 * Makefile.am (src_m4_SOURCES): Only compile shipped getopt module
21 if the system getopt fails M4_GETOPT tests.
23 2006-06-22 Eric Blake <ebb9@byu.net>
25 * Makefile.am (EXTRA_DIST): Distribute gnulib-cache.m4.
26 Reported by Bruno Haible.
28 2006-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
30 * m4/module.c (m4__module_exit): Avoid ltdl memory leak.
32 2006-06-19 Eric Blake <ebb9@byu.net>
36 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
39 (clean-local): Split into and depend upon...
40 (clean-local-tests, clean-local-src): ...these two. The latter
41 removes the libtool object directory below `src', to work around
42 a buglet in Automake, failing to list it.
43 (EXTRA_DIST): Distribute modules/perl.c.
45 2006-06-19 Eric Blake <ebb9@byu.net>
47 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
48 right side of dependency; VPATH does that.
49 (stamp-vcl): Update to use libtool's algorithm.
50 (EXTRA_DIST): Distribute stamp-vcl.
51 Reported by Ralf Wildenhues.
52 (TESTSUITE): Revert earlier change that used absolute path, as
53 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
54 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
55 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
56 atlocal takes care of it instead.
57 (check-local, installcheck-local, clean-local): Inline absolute
58 path to testsuite here, rather than relative path to testsuite
61 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
63 * m4/m4private.h (DELETE): Cast away const here...
64 * src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.
65 * src/freeze.c (reload_frozen_state): Avoid uninitialized
68 2006-06-19 Eric Blake <ebb9@byu.net>
70 * Makefile.am (doc/m4.1): Build in $(srcdir), to match where
71 .info pages are built.
72 Reported by Ralf Wildenhues.
73 (EXTRA_DIST): Inline definition of testsuite, so that make dist
76 2006-06-16 Eric Blake <ebb9@byu.net>
78 Follow recommendations from autoconf manual for autotest.
79 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
80 turn it into an absolute path until autotest provides an option
81 that allows us to avoid changing directories. Properly quote
83 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
84 (check-recursive): Delete unused target.

86 (CD_TESTDIR): Simplify.
87 (m4__cd): Delete unused macro.
88 (check-local): Let TESTSUITEFLAGS influence the run.
89 (installcheck-local): Let TESTSUITEFLAGS override

97 * configure.ac (M4_DEFAULT_PRELOAD): Fix typo in last commit.
99 * ltdl/m4/m4-error.m4 (M4_ERROR): Use M4_ instead of m4_ to avoid
100 clashes with m4sugar.
101 * ltdl/m4/m4-getopt.m4 (M4_GETOPT): Likewise.

107 * ltdl/m4/debug.m4 (M4_CHECK_DEBUGGING): Likewise.
108 * configure.ac: Likewise.
109 (M4_DEFAULT_PRELOAD): Use as a macro, not shell variable.
110 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
112 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
114 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
115 const mpq_t is not assignable from plain mpq_t. Avoid
116 type-punning warnings caused trying to mix these types.
117 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
118 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

129 * Makefile.am (modules_mpeval_la_LIBADD): Readd $(LIBADD_GMP).
131 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
132 Eric Blake <ebb9@byu.net>
134 Allow `make dist' to work again.
135 * Makefile.am (EXTRA_DIST): doc/helptoman.pl is gone.
136 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
137 (cvs-dist): Fix typo.
138 * NEWS: Match current version number.

142 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
145 * bootstrap: Do not run libtoolize manually, this is done
146 correctly by autoreconf. Invoke autoreconf with --no-recursive
147 to avoid unnecessary rerunning of autotools for libltdl.
149 2006-06-13 Eric Blake <ebb9@byu.net>
153 2006-06-12 Eric Blake <ebb9@byu.net>
155 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't

158 * m4/input.c (m4__next_token): Avoid bzero.
159 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
160 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
161 than distributing outdated helptoman.pl.
162 * doc/helptoman.pl: Delete.
164 2006-06-10 Eric Blake <ebb9@byu.net>
166 * README (Patches): Document the current dependence on CVS

175 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
176 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
177 done by gnulib or automake, or which autoconf has declared
179 * m4/m4private.h (Includes): Assume C89 or better, and use errno

193 * ChangeLog: Change encoding to UTF-8.
195 Avoid compiler warnings.
196 * m4/macro.c (trace_format): Don't mark this as a printf format,
197 since we don't accept the same set of modifiers as printf. It
198 would be nice if gcc let us specify a custom format archetype.
199 * src/main.c (main): Cast away const.
201 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
202 Eric Blake <ebb9@byu.net>
204 * modules/time.c (ctime): Pass correctly typed variable to

242 * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
245 2005-12-05 Gary V. Vaughan <gary@gnu.org>
247 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
248 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
249 Reported by Eric Blake <ebb9@byu.net>
251 2005-12-04 Gary V. Vaughan <gary@gnu.org>
253 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
254 http caching as -C is no longer supported by wget 1.10.x.
255 Reported by Eric Blake <ebb9@byu.net>
257 2005-10-20 Gary V. Vaughan <gary@gnu.org>

261 (iface_id): ...an lt_dlinterface_id type.
262 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
263 throughout, instead of calling obsolete lt_dlhandle_find directly.
264 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
265 throughout, instead of calling obsolete lt_dlhandle_next.
266 * m4/m4private.h (m4__module_find): Declare it.
267 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
268 Use m4__module_next instead of obsolete lt_dlhandle_next.

275 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
276 these files under source control anymore.

279 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
281 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
282 file escaped the address updates on 2005-05-01.
284 2005-07-07 Gary V. Vaughan <gary@gnu.org>
286 * bootstrap: Allow user overriding of gnulib-tool location, and
287 correctly determine module source directories whether gnulib-tool
288 is given as a relative or absolute path, or is found by searching

303 * doc/m4.texinfo (History): Add better notes on the ancestory of
304 GNU m4, and other historical interest.
306 2005-05-08 Gary V. Vaughan <gary@gnu.org>

315 macro renaming by regular expression.
316 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
317 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
318 to stop the new generated tests from choking.
320 2005-05-07 Gary V. Vaughan <gary@gnu.org>
322 Since most of the build is handled from a single Makefile.am now,
323 we can teach make about the dependencies between the m4 binary and
324 the preopened modules it is built against:
326 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
328 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
329 of the preopened modules have changed.
331 2005-05-07 Gary V. Vaughan <gary@gnu.org>
333 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
334 have a native implementation.
336 2005-05-06 Gary V. Vaughan <gary@gnu.org>
338 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
339 handled already by gnu/exit.h.
341 * configure.ac (gl_MODULES): Add assert to support a
342 --disable-assert configure time option for NDEBUG setting.
344 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
345 * bootstrap (src_modules): Add version-etc-fsf.
346 * src/main.c (version_etc_copyright): Removed.
348 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.

358 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
360 Forward port of a patch that allowed m4-1.4.2 to compile on
363 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
365 * src/m4.h: And include them as appropriate.
366 * src/main.c, src/stackovf.h: Don't include signal.h literally;
367 m4.h will include the correct file.
369 2005-05-04 Gary V. Vaughan <gary@gnu.org>
371 * m4/m4private.h: Make errno visible for the sources patched
374 2005-05-04 Paul Eggert <eggert@twinsun.com>
376 * src/main.c (print_program_name_CB): Preserve errno, since

378 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
379 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
380 * m4/path.c (m4_path_search): Don't let "free" trash errno when
383 * m4/output.c (m4_insert_file): Don't assume errno has a valid
384 value simply because fread returns zero. This fixes a
385 portability bug reported by Marion Hakanson in
386 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
388 2005-05-04 Santiago Vila <sanvila@debian.org>
390 * tests/stackovf.test: Use tempfile if available.

394 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
395 * m4/output.c (m4_insert_file): Do not mix buffered and
396 unbuffered I/O, as this breaks on the Hurd.
398 2005-05-04 Gary V. Vaughan <gary@gnu.org>
400 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
401 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
402 and libtoolize does a better job of ltdl importing now too, so
403 take advantage of that while updating the tree:
405 * acm4, config: Moved from here...
406 * ltdl/m4, ltdl/config: ...to here.
407 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
408 src/Makefile.am, tests/Makefile.am: Removed...
409 * Makefile.am: ...and migrated to here, with adjustments to
410 compensate for relative path differences.
411 * commit: Adjust relative paths.
412 * configure.ac: Adjust relative paths.
413 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
415 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
416 the meanwhile, CVS HEAD libtool is needed.
417 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
418 stricly new enough, we also need a patch.
419 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
420 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
421 (gl_MODULES): Don't list getopt and version-etc, as they don't
423 * bootstrap: After running gnulib-tool to import the listed
424 modules, fetch getopt and version-etc into src manually.
425 (ltdldir): Change to ltdl.
426 * src/main.c: Adjust for changes in version-etc API.
427 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
428 but works when the getopt module isn't to be included in the lib.
429 * README: Add note about patching autoconf and automake to

435 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
436 empty file rather than to a nonexistent file. This closes a
437 common security hole.
438 * modules/m4.c (m4_maketemp): Implement the above, by using
439 mkstemp rather than mktemp.

488 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
489 (m4_is_syntax_macro_escaped): Similarly protect function
490 definitions from macro expansion under -DNDEBUG by #undefing the
491 matching macro names before each definition. Also, move all the
492 function definitions to the end of the file so that any
493 invocations in the rest of the file pick up the fast macro

506 * gnulib/*: Don't store any of the gnulib files in arch, as they
507 generate spurious changes.

509 gnulib macros now share our macro directory.
510 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
511 * bootstrap: Call gnulib-tool to import from the gnulib tree.
512 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
513 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
514 the gettext macros from autopoint that overwrite the gnulib-tool
515 imported versions. Import sources and Makefile.am into the `gnu'
516 directory. Changed all callers.
517 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
518 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
519 for imported modules.
520 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
521 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
522 hardcoding the gnulib macros they wrap.
524 2004-07-15 Gary V. Vaughan <gary@gnu.org>
526 Latest CVS libtool can preload modules in libraries, including
527 its own module loaders! Tweak m4 so that it doesn't try to treat
528 libltdl's module loaders as m4 modules when freezing and on exit:
530 * gnulib/acm4/*.m4: Don't store these files in arch since they
531 generate spurious changes.
532 * bootstrap: Simplify initial libtoolize call, since CVS
533 libtoolize is smarter these days.
534 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
536 * m4/module.h (m4__module_exit): Missing declaration.
537 * m4/m4private.h (m4__module_next): New function declaration.
538 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
539 encapsulation. Changed all callers.
540 (m4__module_interface): New function to verify m4 loadable module
542 (m4__module_init): Register the interface validator.
543 (m4__module_exit): Only close my own modules.
544 * modules/m4.c (unistd.h): Provide missing declaration.
545 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
546 (m4_expand_ranges): More missing declarations.
547 * modules/modtest.c (export_test): Ditto.
548 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
549 * src/main.c (main): Bump copyright year.
550 * tests/modules.at: Fix sed syntax error.
553 2004-06-17 Gary V. Vaughan <gary@gnu.org>
555 Tweaking to enable compilation with latest CVS libtool and
556 libltdl. We can't just dump the library files directly into the
557 m4 directory anymore now that libltdl is built from pieces itself:
559 * bootstrap: Rewritten to use latest libtoolize sanely, and to
560 set up libltdl subdirectory.
561 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
562 gnulib subdirectory's config.
563 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
564 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
566 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
567 configure.ac, so use AC_WITH_LTDL instead.
568 * Makefile.am (SUBDIRS): Add libltdl.
569 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
571 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
572 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
573 (libm4_la_LIBADD): Add LIBLTDL.
574 * m4/ltdl.c, m4/ltdl.h: Removed.
575 * m4/m4module.h: Include canonical ltdl.h.
578 2004-06-14 Gary V. Vaughan <gary@gnu.org>
580 * gnulib/import: Now updates makefile fragments, and configure.ac.
581 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
582 * gnulib/m4/Makefile.am: include it.
583 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
584 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
585 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
586 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
587 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
588 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
589 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
590 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
591 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
592 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
593 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
594 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
595 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
597 * gnulib/m4/getopt_int.h: New source file from latest gnulib
599 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
600 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
601 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
602 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
603 Updated source files from latest gnulib.
605 2004-02-29 Gary V. Vaughan <gary@gnu.org>
607 * config/mailnotify: New file for mailing commit notifications,
608 imported from cvs-utils.
609 * commit: Updated from cvs-utils and tweaked for m4.
611 2003-12-01 Gary V. Vaughan <gary@gnu.org>
613 * config/mkstamp: Updated from CVS libtool.
614 * configure.ac: Generate a gnu coding standards compliant version
615 number, and use it for the banner.
616 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
617 mhen the TIMESTAMP changes in ChangeLog, but the file modification
618 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
619 contain the previous version number.
620 * src/main.c: Make --version output conform to the GNU standard.
622 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
623 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
624 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
625 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
626 time_la_SOURCES): ...so that these are defaulted correctly, and
627 can be removed from this file.
628 (AM_LDFLAGS): Add -module...
629 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
630 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
631 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
632 the individual settings can be removed.
633 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
634 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
635 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
636 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
637 time_la_LIBADD): ...so that these are picked up as a deplib of
638 libm4 and don't need to be set explicitly.
640 2003-11-18 Gary V. Vaughan <gary@gnu.org>
642 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
643 from the standard build. It is too fragile.
645 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
646 CVS libtool after merging m4 changes across to libtool.
648 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
649 * m4/path.c (search_path_add): Ditto.
651 2003-11-13 Gary V. Vaughan <gary@gnu.org>
653 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
654 libtool tags we don't use in configure. This reduces the size
655 of the script from over 1Mb to under 700Kb.
657 2003-11-13 Gary V. Vaughan <gary@gnu.org>
659 The import script was not written properly, and the last gnulib
660 import was incomplete. Fixed that problem, and reimport our
661 gnulib dependencies, which picks up the address calculation
662 overflow checks described by Paul below. Also tweak the clients
663 of the gnulib xalloc module not to use deprecated macros:
665 * gnulib/import: Recurse through module dependencies rather than
666 naively descending only one level.
667 * configure.ac: Add calls to gnulib's strnlen and extension module
669 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
671 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
672 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
673 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
674 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
676 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
677 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
678 place of `xcalloc (1, S)'.
679 * m4/m4.c (m4_create): Likewise.
680 * m4/m4private.h (m4_symbol_value_create): Likewise.
681 * m4/symtab.c (symtab_fetch): Likewise.
682 * m4/syntax.c (m4_syntax_create): Likewise.
683 * src/freeze.c (reload_frozen_state): Likewise.
684 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
686 * m4/symtab.c (m4_symtab_create): Likewise.
688 2003-11-13 Gary V. Vaughan <gary@gnu.org>
690 * tests/module.at: Comment typo.
692 2003-10-10 Gary V. Vaughan <gary@gnu.org>
694 * tests/modules.at (modules: importing): Apply some lateral
695 thinking, and use AT_CHECK to compare the output of a sed pass
696 over stderr against the canonical strerror string.
698 * tests/modules.at (modules: importing): Edit the generated stderr
699 output to canonicalize strerror output, before a comparison.
701 2003-10-10 Gary V. Vaughan <gary@gnu.org>
703 Tru64UNIX perl is sloppy with namespace pollution. This patch is
704 careful not to trip over the mess:
706 * modules/perl.c: Some builds of perl install headers that contain
707 `#define try __builtin_try'. Be sure to undefine that macro
708 before `m4/hash.h' gets included, which uses the `try' symbol.
709 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
710 `false' before including `stdbool.h'.
711 (DELETE): This symbol is not in m4's namespace, and is in any
712 case only used internally...
713 * m4/m4private.h (DELETE): ...so move it to here.
714 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
716 2003-10-08 Paul Eggert <eggert@twinsun.com>
718 Don't use XMALLOC and XCALLOC. Once we install the
719 corresponding patch into gnulib, this will fix some
720 address-calculation overflow bugs on hosts where calloc (A, B)
721 returns garbage when A*B overflows.
723 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
724 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
725 xmalloc, XCALLOC with xcalloc.
726 * m4/m4.c (m4_create): Likewise.
727 * m4/m4private.h (m4_symbol_value_create): Likewise.
728 * m4/output.c (m4_output_init): Likewise.
729 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
730 * m4/syntax.c (remove_syntax_attribute): Likewise.
731 * src/freeze.c (reload_frozen_state): Likewise.
732 * src/main.c (main): Likewise.
734 2003-10-07 Gary V. Vaughan <gary@gnu.org>
736 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
737 gnulib/acm4 directories for aclocal m4 macros.
738 * gnulib/Makefile.am (EXTRA_DIST): Removed.
739 (MAINTAINERCLEANFILES): Add Makefile.in.
740 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
742 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
743 * gnulib/import: New file. Temporary script for updating gnulib
744 imported files, until gnulib-tool is working.
745 * gnulib/config/codeset.m4, gnulib/config/error.m4,
746 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

783 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
784 gnulib/import script.
785 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
786 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

789 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
790 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
791 gnulib with gnulib/import script.
792 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
793 guards ready for gnulib-tool to autoupdate on import.

795 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
796 config/stackovf.m4: Moved from here...
797 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
798 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,

802 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
803 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,

808 (version_etc): Call with new variadic API.
810 2003-09-16 Gary V. Vaughan <gary@gnu.org>
812 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
813 version-etc module from CVS gnulib.
814 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
815 * src/Makefile.am: Build it.
816 * src/main.c: Use it.

819 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
820 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
823 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
824 Gary V. Vaughan <gary@gnu.org>
826 * bootstrap: Separate options.
827 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
828 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
830 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
831 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
832 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
833 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
834 $(LTLIBINTL) for gettext support on cygwin.
835 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
836 have $(LTLIBINTL) from the preloaded module la files.
837 * README: Remove the warning about using --disable-nls on Windows
840 2003-09-15 Gary V. Vaughan <gary@gnu.org>
842 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
843 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
846 2003-09-12 Gary V. Vaughan <gary@gnu.org>
848 * doc/STYLE: Document the gnulib header naming conventions, and
850 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
851 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,

857 module from CVS gnulib.
858 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
859 (gl_FUNC_STRTOL): In favour of the module macro.
861 2003-09-12 Gary V. Vaughan <gary@gnu.org>
863 Replace the getopt code with CVS gnulib getopt. The source files
864 detect whether they are in a glibc environment and preprocess away
865 all of the code if there is a system getopt, so we can compile
866 them into the m4 executable unconditionally:
868 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
869 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
870 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
872 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
874 * src/Makefile.am: Adjust.
875 * src/main.c: Always include our shipped getopt.h.
876 * po/POTFILES.in: Use new location of getopt.c.
878 2003-09-12 Gary V. Vaughan <gary@gnu.org>
880 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
881 * config/Makefile.am: Removed. Automake 1.8 distributes the files
882 in this directory automatically.
883 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
885 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
887 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
889 * modules/Makefile.am (pkglibexecdir): Set it here.
890 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
892 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
893 Import regex module from CVS gnulib.
894 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
895 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
896 do extra substitutions for Makefile.
897 * configure.ac: Use it.
898 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
899 from regex_.h if necessary.
900 * m4/system_.h: Include the correct version of regex.h.
901 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
903 * po/POTFILES.in: Use new location of regex.c.
905 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
906 realloc.c: automake distributes these files already.
908 2003-09-12 Gary V. Vaughan <gary@gnu.org>
910 Replace the xstrzdup code by importing the xstrndup module from
911 CVS gnulib, along with its dependencies: strndup and strnlen:
913 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
914 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
916 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
917 gnulib/config/strndup.m4: Ditto wrt strndup.
918 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
920 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
921 However, contrary to gnulib, we install xstrndup.h.
922 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
923 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
924 is an artifact of the old m4 portability layer.
925 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
926 * m4/system_.h: Include xstrndup.h.
927 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
929 2003-09-11 Gary V. Vaughan <gary@gnu.org>
931 Reimport the latest xalloc module from CVS gnulib, and adjust the
932 m4 sources to take advantage of xalloc xfree. Also create a new
933 macro DELETE with the same semantics as the old m4 XFREE macro,
934 and carefully tweak callers:
936 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
938 * m4/utility.c (xfree): Removed. This function is now supplied by
940 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
941 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
942 * m4/symtab.c (m4_symtab_create): Ditto.
943 * m4/system_.h: Removed XFREE redefine.
944 (DELETE): New macro with same functionality as the original m4
945 XFREE macro, but based on xalloc.h now. Changed all callers.
946 * src/main.c (main): Use XMALLOC macro.
947 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
949 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
951 2003-09-10 Gary V. Vaughan <gary@gnu.org>
953 Import the xalloc module from CVS gnulib, along with its
954 dependencies: exitfail, malloc and realloc. We had different
955 semantics for our XFREE and a function xfree() not supplied by
956 gnulib, so also a bit of work to keep everything running
959 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
960 (gl_XALLOC): Use gnulib equivalents.
961 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
962 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
963 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
964 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
966 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
967 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
968 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
970 (pkgincdir): Removed. Use pkgincludedir instead.
971 * m4/m4private.h (XFREE): xfree already checks for NULL.
972 * m4/system_.h: Use xalloc module, and remove macros already
973 supplied by xalloc.h.
974 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
975 moved the old definition from m4/xmalloc.c to here for now.
977 2003-09-09 Gary V. Vaughan <gary@gnu.org>
979 Import the error and progname modules from CVS gnulib. Our old
980 error.c subsumed the functionality of both, so a little adjustment
981 was required to accomodate the split in sources. Also added more
982 wrapper macros to choose between a system installed error.h or our
983 shipped gnulib error module:
985 * m4/error.c, m4/error.h: Removed.
986 * m4/Makefile.am: Adjust.
987 (pkgincdir): Removed. Use pkgincludedir instead.
988 * m4/module.h, src/main.c: Don't include `m4/error.h'.
989 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
991 * gnulib/m4/progname.c: Imported from CVS gnulib.
992 * gnulib/m4/progname.h: Ditto.
993 * src/main.c: Adjust to use progname module.
994 * gnulib/m4/error.c: Imported from CVS gnulib.
995 * gnulib/m4/error_.h: Ditto.
996 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
997 if appropriate, and link a local error.h if the system version is
999 (libgnu_la_SOURCES) Add progname module sources.
1000 * gnulib/config/error.m4: Imported from CVS gnulib.
1001 * gnulib/config/strerror_r.m4: Ditto.
1002 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
1003 to have ERROR_H for Makefile substitutions and tell system.h
1004 whether the system error.h should be used, or a locally installed
1006 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
1008 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1010 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
1011 s/gettext_.h/gettext.h/.
1013 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
1014 automake have been fixed.
1016 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
1017 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
1018 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
1019 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
1021 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1023 The gnulib obstack module requires the gnulib gettext module for
1024 systems that do not have GNU gettext installed. Because we use
1025 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
1026 that directory incase it clashes with the system gettext.h. This
1027 delta uses gettext_.h and extra rules in the Makefile to make a
1028 link to gettext.h when needed:
1030 * Makefile.am (auxdir): Removed. No longer used.
1031 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
1032 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
1034 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
1035 Makefile based build.
1036 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
1037 of the macros are kept.
1038 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
1039 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
1040 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
1041 distributes these automatically.
1042 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
1043 warning from automake-1.7a.
1044 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
1045 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
1047 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
1048 wrt. m4_FUNC_OBSTACK.
1049 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
1050 wrt. m4_sys_STACKOVF.
1051 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
1052 wrt. _m4_LIB_GMP, m4_LIB_GMP.
1053 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
1054 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
1056 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
1057 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
1058 gettext.h link on deficient systems.
1059 (pkginc_HEADERS): Mention $(GETTEXT_H).
1060 (EXTRA_HEADERS): Mention gettext.h.
1061 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
1062 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
1063 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
1064 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
1065 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
1066 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
1067 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
1068 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
1069 gnulib/config/po.m4, gnulib/config/progtest.m4,
1070 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
1071 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
1073 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1075 We can't mirror the gnulib directory structure here, since we need
1076 to be able to eg. `#include <m4/obstack.h>' from our source files,
1077 which is much easier if the local obstack.h is created in a
1078 directory named m4. Rather than trying to symlink everything into
1079 the m4 directory, now we build a libtool convenience library from
1080 the sources we get from gnulib and link that with libm4.la:
1082 * gnulib/config/extensions.m4: Imported from CVS gnulib.
1083 * gnulib/config/unlocked-io.m4: Ditto.
1084 * gnulib/m4/unlocked-io.h: Ditto.
1085 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
1086 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
1087 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
1088 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
1089 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
1090 * m4/Makefile.am: Adjust.
1091 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
1092 macros we redistribute.
1093 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
1094 library among others.
1095 (GNULIB_SRCS, GNULIB_MACROS): Removed.
1096 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
1097 * config/m4-obstack.m4: Adjust.
1098 * po/POTFILES.in: Adjust.
1099 * configure.ac: Reformatting. Call newly imported gnulib macros.
1100 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
1101 bogus calls of `#include "m4.h"'.
1102 * Makefile.am: INCLUDES has been deprecated in favour of
1104 * m4/Makefile.am: Ditto.
1105 * modules/Makefile.am: Ditto.
1106 * src/Makefile.am: Ditto.
1108 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1110 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
1112 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1114 Migrate the obstack support into the gnulib directories for easy
1115 synchronisation with upstream files in gnulib:
1117 * config/gnu-obstack.m4: Moved from here...
1118 * config/m4-obstack.m4: ...to here.
1119 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
1120 * m4/obstack.c, m4/obstack_.h: Moved from here...
1121 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
1122 * po/POTFILES.in: Adjust.
1123 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
1124 * m4/Makefile.am: Add a whole new section to link the obstack
1125 sources from the gnulib tree if necessary.
1126 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
1128 * config/m4-obstack.m4: Rewrite as a wrapper for
1129 gnulib/m4/obstack.m4.
1131 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1133 GNU M4 currently builds with a number of files adapted from
1134 upstream sources. Recently the gnulib project on savannah.gnu.org
1135 has pulled together a great many of these externally maintained
1136 files. This delta is the beginnings of isolating those files
1137 maintained in gnulib to make it easy to synchronise M4 with the
1138 upstream files prior to releases.
1140 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
1142 (SUBDIRS): Added new gnulib subdirectory.
1143 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
1144 * config/stdbool.m4: Moved from here...
1145 * gnulib/m4/stdbool.m4: ...to here.
1146 * m4/stdbool_.h: Moved from here...
1147 * gnulib/lib/stdbool_.h: ...to here.
1148 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
1150 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
1151 code to work with new stdbool_.h location.
1152 (gnulib_srcdir): New.
1154 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1156 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
1157 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
1159 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
1160 (EXTRA_DIST): Use it.
1162 * bootstrap: CVS autoreconf leaves file droppings. Remove
1163 aclocal.m4t incase autoreconf doesn't.
1165 2003-08-29 Gary V. Vaughan <gary@gnu.org>
1167 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
1168 the other gnulib imports, renamed to m4/obstack_.h.
1169 * m4/obstack.c: Updated from CVS gnulib.
1170 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
1171 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
1172 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
1173 about vpath already, and $top_srcdir upsets CVS Automake, so the
1174 $top_srcdir reference was removed.
1176 * m4/system-h.in: For consistency with the gnulib imports, renamed
1178 * m4/Makefile (EXTRA_HEADERS): Adjust.
1179 * configure.ac (AC_CONFIG_FILES): Adjust.
1181 * m4/stdbool_.h: New file from gnulib for systems without their
1183 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
1184 * config/stdbool.m4: New file. Macros from gnulib for same.
1185 * configure.ac: Use it.
1187 2003-08-27 Gary V. Vaughan <gary@gnu.org>
1189 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

1236 * src/main.c: Ditto.
1237 * src/stackovf.c: Ditto.
1239 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
1240 ac_default_headers is an autoconf internal variable.
1241 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
1242 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1244 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
1245 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
1248 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1250 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
1252 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
1253 possible or faking one with a typedef. Changed all callers.
1255 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1257 Still cleaning up the users' module API, by taking out the stuff
1258 that isn't used by any existing modules, and moving specialised
1259 functions out of libm4 and into the module they are used by.
1261 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
1262 * m4/utility.c (m4_skip_space): ...to here the home of its only
1263 use, made static and renamed to `skip_space'. Changed all
1265 * m4/m4module.h (m4_expand_ranges): Removed prototype.
1266 * m4/utility.c (m4_expand_ranges): Moved definition from here...
1267 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
1269 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
1271 * modules/gnu.c (builtin_syntax): Import and use in this
1272 builtin implementation.
1273 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
1275 * m4/macro.c (trace_flush): Except here where the macro is now
1277 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1278 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
1280 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1281 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
1283 2003-08-14 Gary V. Vaughan <gary@gnu.org>
1285 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
1286 compiler based AC_CHECK_HEADER that was introduced in
1288 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1289 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
1290 * configure.ac: Use renamed M4_AC_LIB_GMP.
1292 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
1293 macro that requires arguments! This stops the shell's bad
1294 substitution error at configure time.
1296 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
1297 variables to the testsuite shell. Set the value of USE_GMP so
1298 that the gmp test will run!
1299 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
1301 2003-08-11 Gary V. Vaughan <gary@gnu.org>
1303 Libltdl already has an excellent mechanism for accessing C symbols
1304 in modules. Lets use that! Remove all the exporting cruft and
1305 just use lt_dlsym in conjunction with a few conventions to
1306 simplify module writers' jobs. Also removed the table address
1307 caching code and otherwise simplified the module loader quite a
1308 bit. To access exported symbols in other modules, first the
1309 exporting module must name the symbols <modname>_LTX_<symname>,
1310 and the importing module must define a function type called
1311 <symname>_func. The importer then adds
1312 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
1313 that wishes to call out to the exported functions. Care must be
1314 taken that <symname> is non-NULL in the importing module incase
1315 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
1316 definition was in the importers source. Study
1317 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
1318 m4_module_import will attempt to automatically load a module
1319 required for symbol access if it is not loaded already.
1321 * TODO: Removed the items fixed in this delta.
1322 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
1324 * m4/ltdl.h (lt_dlhandle_find): Declare it.
1325 * m4/module.c (m4_module_unload): Use it.
1326 * src/freeze.c (reload_frozen_state): Ditto.
1327 * m4/m4module.h (m4_export): Deleted. Removed all references.
1328 (M4_MODULE_IMPORT): New user convenience macro for importing
1329 arbitrary symbols from other modules.
1330 * m4/module.c (m4_module_import): New function to service
1331 M4_MODULE_IMPORT macro.
1332 (module_data): Removed. Looking up the tables on demand with
1333 lt_dlsym, rather than caching their addresses here simplifies the
1335 (m4_get_module_builtin_table, m4_get_module_macro_table):
1336 Removed. Changed all callers.
1337 (set_module_macro_table, set_module_builtin_table): Renamed to
1338 install_macro_table and install_builtin_table respectively, and
1339 simplified now that the cache is no more.
1340 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1341 import m4_dump_symbols from the m4 module.
1342 (builtin_esyscmd): Likewise for m4_set_sysval and
1344 * modules/m4.c (m4_export_table): Removed. Functions are
1345 addressed with the new mechanism which doesn't need this.
1346 (m4_set_sysval): New exported accessor function to prevent
1347 problems with variable access on inferior architectures.
1348 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1349 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1350 that we can have some type safety.
1351 * modules/modtest.c (export_test): C level exported function for
1352 testing the new import mechanism.
1353 * modules/import.c: New file for the import end of the test.
1354 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1355 * tests/modules.at: New test cases for intermodule symbol
1358 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1360 * m4/m4module.c (m4_string): Moved from here...
1361 * m4/m4private.c (m4_string): ...to here.
1363 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1365 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1367 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1368 already available to module writers through
1369 m4_{get,set}_nesting_limit_opt(), so moved from here...
1370 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1371 (m4_create): Use it.
1373 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1375 Aside from auditing path.c for m4module.h api obfuscation, this
1376 delta introduces the concept of private struct members in opaque
1377 data types to GNU m4: See the STYLE file for details.
1379 * TODO: Remind ourselves that a rewrite of path.c is needed.
1380 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1382 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1383 here and renamed. These type definitions are for internal api use
1384 only. Changed all callers.
1385 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1387 * m4/path.c (search_path_env_init, search_path_add): ...to here
1388 and renamed. These calls were never used outside this file.
1389 Changed all callers.
1390 (dirpath): Moved functionality of this static declaration...
1391 * m4/m4private.h (struct m4): ...to this new internal only
1392 search_path field. Changed all callers.
1393 (m4__get_search_path): Added new internal api accessor.
1394 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1395 (m4_include_init): Removed...
1396 * m4/m4.c (m4_create): ...because the new m4 field is now
1398 (m4_delete): Recycle search_path memory.
1399 * src/main.c (main): Don't call m4_include_init now that it's
1401 * doc/STYLE: Document convention for private fields in opaque
1404 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1406 Sometimes exporting the address of a symbol from a module isn't
1407 enough for other modules to call that symbol correctly. If
1408 custom data types are used for function parameters, they need to
1409 be known to the caller. This change introduces the concept of
1410 $(prefix)/include/modules/$(modulename).h to declare those
1411 structures. Also we move m4_dump_symbols from libm4 to the m4
1412 module to show this concept in action.
1414 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1415 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1416 exporting data structures from modules/m4.c.
1417 * modules/m4.c, modules/gnu.c: Include it.
1418 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1419 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1421 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1423 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1424 ...to here, with slight renaming.
1425 (m4_export_table): Prototype and add m4_dump_symbols.
1426 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1427 definition of m4_dump_symbols.
1428 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1429 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1431 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1433 Create an export table in modules/m4.c in readiness for beefing up
1434 the module loader to track module exports and imports.
1436 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1437 * m4/debug.c (m4_debug_flush_files): Moved...
1438 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1439 * modules/gnu.c (builtin_esysval): Use it.
1440 * m4/m4module.h (m4_export): New type for declaring module symbols
1442 * modules/m4.c (m4_export_table): List symbols exported from this
1443 module for use by other modules.
1445 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1447 An experiment: There is loads of code in libm4 which should be in
1448 the m4 module, but is also used by another module. Just because
1449 some linkers won't cope with calls across dynamic runtime loaded
1450 objects I initially left the code in libm4. It will tidy the
1451 module api immensely if this code moves to the right place, I just
1452 need to remember to invent a suitable calling mechanism at some
1453 point. For now, only modules that are statically linked and
1454 preloaded will get this treatment, so the only platforms that will
1455 break are those that require all symbols to be resolved at link
1458 * TODO: Reminder that what I am doing could reduce portability
1459 unless I do something more robust later.
1460 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1461 * m4/utility.c (m4_sysval): No longer declared in libm4.
1462 * modules/Makefile.am: Reformatting.
1463 * modules/m4.c (m4_sysval): Declare it at place of use.
1464 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1466 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1468 * m4/m4module.h: Reformatting and rearranging lines a bit.
1469 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1471 (m4_call_macro, m4_expand_input): Renamed...
1472 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1474 (m4_expansion_level, m4_process_macro): Moved...
1475 * m4/macro.c (expansion_level, process_macro): ...to here, and
1478 * m4/m4module.h (program_name): Not used by modules at all, so
1480 * src/main.c (program_name): ...to here.
1481 (print_program_name): Renamed...
1482 (print_program_name_CB): ...to conform to the STYLE guide.
1484 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1486 More refactoring of the m4module.h API. Replace #defines with an
1487 enum, and move non-public functions out of the public API.
1489 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1491 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1492 * m4/debug.c (m4_debug, trace): Moved...
1493 * m4/m4private.h (struct m4): ...to fields of this struct.
1494 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1496 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1497 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1498 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1499 * m4/m4module.h (m4_context_field_table): Add entries for new
1500 debug_file and trace_messages fields.
1501 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1502 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1503 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1504 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1505 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1506 (m4_is_debug_bit): New macro to simplfy checks against the debug
1508 (m4_trace_format, m4_trace_header, m4_trace_flush)
1509 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1511 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1512 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1513 * m4/macro.c (trace_format, trace_header, trace_flush)
1514 (trace_prepre, trace_pre, trace_post): ...to these newly static
1515 functions, since they are only ever used from this file. Changed
1518 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1520 Change the macros for checking syntax so that matching against
1521 multiple possible syntax classes can be done with a single
1522 comparison some of the time. The various classes are now bits of
1523 an int that can be checked with bitwise logic operators.
1525 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1526 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
1527 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
1528 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
1529 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
1530 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
1531 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
1532 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
1533 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
1534 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
1535 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1536 Replace all calls with invocations of these...
1537 (m4_is_syntax, m4_has_syntax): ...New macros.
1538 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1539 is no longer required with new macros. Changed all callers.
1541 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1543 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1544 values are returned as part of the internal interface, so they
1546 * m4/private.h: ...to here.
1547 * m4/macro.c (expand_token): Check for out of range
1548 m4_peek_input() results before looking up in the syntax table.
1549 (collect_arguments): Ditto.
1551 * NEWS: Note `$' syntax class.
1553 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1554 Gary V. Vaughan <gary@gnu.org>
1556 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1557 --traditional `define' now smashes all the definitions.
1559 * NEWS: Explain this.
1560 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1561 (Extensions): Explain that extensions that are incompatible with
1562 POSIX are disabled if POSIXLY_CORRECT is set.
1563 (Incompatibilities): Remove.
1564 (Define, Other Incompat): Explain difference
1565 between GNU and POSIX behavior of define, pushdef, popdef.
1566 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
1567 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
1568 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
1569 (m4_get_posixly_correct_opt): New macro.
1570 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
1572 * modules/m4.c (builtin_functions): defn now takes any number of args.
1573 (builtin_define): Smash all the definitions if
1575 (builtin_defn)): Allow any number of arguments.
1576 (builtin_undivert): Do not allow nonnumeric arguments
1578 * src/main.c (main): Set posixly-correct behavior if either
1579 POSIXLY_CORRECT is set, or if -G is given.
1580 * tests/builtins.at: New test for smashed definitions.
1582 2003-06-27 Gary V. Vaughan <gary@gnu.org>
1584 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1585 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1586 not to slow the parser down.
1587 (M4__IS_STRING): New macro to test string syntax class membership.
1588 * m4/syntax.c: Adjust docucomment.
1589 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1590 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1591 * m4/input.c (init_builtin_token): Comment typo.
1592 (m4__next_token): Comment typo.
1593 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1594 by using the new M4__IS_STRING macro.
1595 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1596 variable references in macro expansions.
1598 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1599 (Epatsubst and Patsubst): Typo.
1602 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1604 Move the global variables that pertain to syntax to a new `struct
1605 m4_syntax_table', and then add one of these to `struct m4'. The
1606 ripple effect through the code to both change formerly global
1607 references, and make sure a suitable context is available in
1608 lexical scope is disproportionately large compared to the size of
1609 the change proper. This change is a large part of decoupling
1610 syntax.c from the rest of the code that uses it.
1612 * m4/m4private.h (struct m4): Add a syntax field.
1613 * m4/m4.c (m4_create): Initialise it,
1614 (m4_delete): Recycle it.
1615 (m4_get_symtab): Remove hand coded version...
1616 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1618 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1619 can generate m4_get_symbol_table. Add a new row for
1620 m4_get_syntax_table.
1621 (M4SYNTAX): Syntactic sugar for module writers.
1622 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1623 (m4_syntax_table): New home for syntax related formerly global
1625 * m4/m4private.h (struct m4_syntax_table): Define it.
1626 * m4/input.c (m4_input_init): Initialisation of these formerly
1627 global variables moved...
1628 * m4/syntax.c (m4_syntax_create): ...to here.
1629 * m4/input.c (m4_input_exit): And similarly, recycling of the
1630 memory used by those values moved...
1631 * m4/syntax.c (m4_syntax_delete): ...to here.
1632 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1633 Moved to m4/m4private.h.
1634 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1635 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1636 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1637 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1638 objects. Changed all callers that used to directly access the
1640 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1641 Removed and incorporated into m4_syntax_table structure.
1642 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1643 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1644 instead of requiring a `struct m4' to generate its own errors.
1645 Changed all callers.
1646 * src/main.c (main): Now that the syntax table is initialised as
1647 part of m4_create, we have to manually wipe the syntax entries if
1648 we are about to read a frozen file.
1650 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1652 * doc/STYLE: Added notes on callback naming schemes.
1654 * m4/module.c (m4_set_module_macro_table)
1655 (m4_set_module_builtin_table): Declarations weren't changed when
1656 definitions were renamed on 2003-06-19.
1658 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1659 neither used nor particularly appropriate since it exposes the
1660 internal workings of the hash module. I haven't yet decided
1661 whether to remove it entirely.
1663 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1665 Two related changes, and a huge knockon effect throughout the
1666 source: Moved the option variables out of global space and into
1667 `struct m4'; made `m4_symtab' a real datatype, so that its api
1668 is not marred passing `struct m4' around just so it can decide
1669 whether to keep traced symbol names or not. Added setters and
1670 getters for the formerly global option variables, and obviously
1671 changed a vast number of functions to take a `struct m4' and use
1672 the getter funcs to find option values.
1674 * m4/utility.c (interactive, sync_output, debug_level)
1675 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1676 (max_debug_argument_length, warning_status, nesting_limit)
1677 (discard_comments): Removed.
1678 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1679 (debug_level, max_debug_argument_length, prefix_all_builtins)
1680 (suppress_warnings, discard_comments, interactive, sync_output):
1681 Removed from here...
1682 * m4/m4private.h (struct m4): ...and equivalent fields added to
1684 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1685 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1686 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1687 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1688 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1689 macros for the new fields.
1690 * m4/m4module.h (m4_context_field_table)
1691 (m4_context_opt_bit_table): Helper macros used to generate
1692 prototypes, setters and getters for new option fields
1694 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1695 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1696 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1697 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1698 (m4_get_interactive_opt, m4_get_sync_output_opt)
1699 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
1700 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
1701 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
1702 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1703 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1704 setter and getter functions generated by cpp from
1705 m4_context_field_table and m4_context_opt_bit_table, exported as
1706 part of the module api. Changed all callers.
1707 * m4/symtab (struct m4_symtab): Used as the concrete type for
1709 (m4_symtab_create): Allocate and initialise a new struct.
1710 (m4_symtab_apply): New function that works like m4_hash_apply, but
1711 with different callbacks specific to symbol tables. Changed all
1713 (symbol_destroy, arg_destroy, arg_copy): Renamed
1714 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1715 they have unused parameters for a reason!
1716 (dump_symbol_CB): New callback to dump the contents of a single
1718 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1719 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1720 Changed all callers.
1721 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1722 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1723 Although I'm not convinced these semantics are correct, they are
1724 at least consistent with how things were before this delta. Also
1725 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1727 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1729 Tie down the interface to libm4 some more. Make more structures
1730 opaque to modules by moving them to m4private.h, and writing
1731 setters and getters. To win back the speed penalty for doing this
1732 also wrote macroized versions that do know about structure layout
1733 in m4private.h and #include that file into modules when NDEBUG is
1734 defined at compile time. There are still some accessor macros in
1735 m4private.h that need to go, but that is not necessary to clean
1738 * m4/m4module.h (m4_symbol_type): Moved...
1739 * m4/m4private.h (m4__symbol_type): ...to here.
1740 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1741 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1742 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1743 (m4_get_symbol_func, m4_symbol_value_create)
1744 (m4_symbol_value_delete, m4_set_symbol_value_text)
1745 (m4_set_symbol_value_func): New exported api to symbols.
1746 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1747 and m4_is_symbol_value_func.
1748 * m4/m4module.h: Prototype these guys.
1749 * m4/module.c (m4_set_module_macro_table)
1750 (m4_set_module_builtin_table): Make these static, there is no
1751 reason to pollute the api with them.
1752 * m4/m4private.h: Reformatting.
1753 (m4_get_symtab): Only define when NDEBUG is defined.
1754 (m4_get_symbol_value, m4_get_symbol_traced)
1755 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1756 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1757 (m4_get_symbol_func, m4_symbol_value_create)
1758 (m4_symbol_value_delete, m4_set_symbol_value_text)
1759 (m4_set_symbol_value_func): Macro implementations of the new
1760 functions when NDEBUG is defined.
1761 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1762 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1763 Superceded by the above. All callers changed.
1764 (M4ARG): Removed. This is no longer different to the
1765 m4/m4module.h definition.
1766 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1767 NDEBUG is defined. That way we exercise the same (albeit slower)
1768 api that external modules must use.
1770 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1772 Renamed some of the types and their accessors to make more sense.
1773 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1774 has a stack of SYMBOL_VALUEs.
1776 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1777 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1778 m4_get_symbol_value_type, m4_get_symbol_value_text,
1779 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1780 Changed all callers.
1781 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1782 (m4_get_token_type): Renamed
1783 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1784 to the internal api.
1785 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1787 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1788 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1789 (m4__token_type): Moved here from m4module.h.
1790 (m4__next_token): Renamed from m4_next_token.
1791 * m4/symtab.c: Removed some of the parameterised macro support
1792 functions for modularisation later.
1793 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1794 m4_hash_dup to perform a true deep copy of the SRC.
1795 (arg_copy): Callback for m4_symbol_value_copy.
1796 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1797 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1798 m4_get_symbol_value_func. Changed all callers.
1800 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1802 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1804 * m4/hash.c: Internal symbol renaming and formatting.
1805 (m4_hash_dup): New function to facilitate deep copies of hash
1807 (m4_hash_apply_func): Returns a void* now, which is a richer type
1808 for returning exceptions (NULL means keep going).
1809 (m4_hash_apply): Ditto.
1810 * m4/hash.h: Declare exported symbols with an explicit extern.
1813 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1815 Still refactoring furiously. This delta represents a change in
1816 semantics to symtab.c. Instead of building temporary m4_tokens
1817 in the caller, and copying fields in the methods, we now create
1818 the actual m4_token for hashing in the caller so the methods just
1819 slot them in directly. Also, this means that we don't lookup a
1820 symbol and get back an allocated but VOID token to copy fields
1821 into, we create the token we want to push and pass that to
1822 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1823 a few other small changes to stop knowledge of the implementation
1824 of symtab.c leaking out into other files.
1826 * m4/macro.c (expand_argument): Comment typo corrected.
1827 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1829 (m4_symbol_pushdef): Take an extra value parameter and use this
1830 directly as the new top of the value stack. All callers changed
1831 to build a token and pass responsibility for memory in, rather
1832 than copying as we used to.
1833 (m4_symbol_define): Also use the new value parameter directly as a
1834 replacement for the top of the value stack. All callers changed
1835 to build a token as above.
1836 (m4_set_symbol_traced): New function to set the traced bit on the
1837 named symbol, creating it if necessary.
1838 (symbol_popval): The guts of the old m4_symbol_popdef.
1839 (m4_symbol_popdef): Use it.
1840 * m4/builtin.c (m4_symbol_set_token): Removed,
1841 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1843 * m4/module.c (m4_set_module_builtin_table)
1844 (m4_set_module_macro_table): ...with these more orthogonal
1846 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1847 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1849 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1850 (m4_arg_signature_parse): Moved...
1851 * m4/symtab.c: ...to here.
1852 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1853 screw something up. Moved...
1854 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1855 actually does a proper deep copy of source to dest.
1857 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1859 Further refactoring to stabilise the module API. Renaming some
1860 functions for orthogonality, and judicious definition migration to
1861 move things out of the set of exported symbols.
1863 * doc/STYLE: New file. Notes on coding style.
1864 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1866 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1867 m4_get_module_name, m4_get_module_builtin_table,
1868 m4_get_module_macro_table which are verb phrases. Changed all
1870 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1872 * m4/module.c (m4_set_module_builtin_table)
1873 (m4_set_module_macro_table): ...here, and renamed. Changed all
1875 * m4/m4module.c (m4_module_data): This...
1876 * m4/m4private.c (struct m4_module_data): ...and this...
1877 * m4/module.c (module_data) ...consolidated here and no longer
1878 exported. Changed all callers.
1880 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1882 Begin work on lifting the curse of the global variables. To start
1883 with create a `struct m4' context container, and replace
1884 `m4__symtab' with `context->symtab' throughout. This means
1885 initialising a context container in main, and adjusting many
1886 functions between main and the module entry points so that the
1887 container gets passed through. It would have been nice to
1888 defer this until after 1.5, but it has a major effect on the
1889 user's module writing ABI, so it needs to be addressed now - at
1890 least in the areas that impact the ABI. An interrelated change
1891 in the symtab API removes the dependency on a global symbol table,
1892 and instead focuses on a passed table (from the context
1895 * TODO: Reminders for finishing context functionality.
1896 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
1897 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
1898 global variables and eventually allow m4 to be reentrant.
1899 * m4/m4private.h (m4): Define the new structure here...
1900 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
1901 don't carry the overhead of a function call.
1902 * m4/m4module.h: Prototype extern functions from m4/m4.c.
1903 (m4): Declare type for new struct m4 objects.
1904 (M4SYMTAB): User macro to ease finding the symbol table for the
1905 current context for module developers.
1906 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
1908 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
1909 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
1910 (m4_call_macro, m4_dump_symbols, m4_expand_input)
1911 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
1912 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
1913 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
1914 m4* context parameter. Changed definitions and all callers.
1915 (m4_symtab): Alias for m4_hash to decouple the
1916 m4_symtab api from m4_hash.
1917 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
1919 (m4_symtab_create): New function to return an initialised
1921 (m4_symtab_delete): New function to delete an m4_symtab's memory.
1922 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
1923 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
1924 instead of simply using the global m4__symtab. Changed
1925 definitions and all callers.
1926 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
1927 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
1928 * src/main.c (main): Create a context and use that instead of the
1929 former global m4__symtab.
1931 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1933 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
1934 to the callback. Callbacks should not need to hardcode the
1935 hashtable they are working from, nor should we have to waste the
1936 userdata parameter to pass the table in.
1937 * m4/hash.h (m4_hash_apply_func): Require the initial table
1939 * m4/symtab.c (symtab_destroy): Use the passed table instead
1940 of hardcoding m4__symtab.
1941 (m4_symbol_popdef): Don't use the userdata parameter to pass the
1942 table to arg_destroy.
1943 (arg_destroy): Use the hash parameter, ignore userdata.
1944 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
1946 (traceon, traceoff): Call set_trace with the extra initial
1949 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1951 More refactoring to stabilise the module api, this time for
1952 symtab.c. Additionally, start to pay attention to function names
1953 that don't contain a verb like they should.
1955 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
1956 wrapper for m4_hash_apply to decouple the symtab module from the
1958 (m4_symbol_builtin, m4_symbol_macro): Renamed to
1959 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
1961 (m4_symbol_delete): Create a macro version to save a function
1963 (m4_token_t, m4_data_t): These violate the POSIX reserved
1964 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
1966 (m4_token_type): Renamed to m4_token_get_type.
1967 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
1968 (m4_symtab_exit): Removed from the exported module
1970 * m4/m4private.h (m4__symtab, m4__symtab_init)
1971 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
1972 renamed and added to the internal api. Changed all callers.
1973 (m4_symtab_apply): A faster macro version of the function for
1974 users of the internal api.
1975 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
1976 symbol_destroy and arg_destroy.
1977 (symtab_debug): Added a prototype.
1978 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
1979 so that callers in this file get the faster macro versions from
1982 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1984 Refactoring modules to rationalise the API into an external
1985 documented (eventually!) API for use by modules in the `m4_'
1986 namespace declared in m4/m4module.h, an internal API between the
1987 source files we ship (including our shipped modules) in the `m4__'
1988 namespace declared in m4/m4private.h and making the rest as
1989 cohesive as possible with liberal use of the `static' keyword.
1990 This change represents an audit to m4/module.c along these
1993 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
1994 Removed. No longer used.
1995 (m4_module_close): Removed prototypes.
1996 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
1997 from the exported module api...
1998 * m4/m4private.h (m4__module_init, m4__module_open)
1999 (m4__module_exit): ...and renamed and added to the internal api.
2000 Changed all callers.
2001 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
2002 Centralised definitions after renaming...
2003 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
2004 (M4_FINISH_SYMBOL): ...and removing from here.
2005 (m4_module_dlerror, m4_module_remove, m4_module_close)
2006 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
2007 module_remove, module_close and caller_id.
2008 (MODULE_SELF_NAME): New macro to make reporting self errors
2010 (m4_module_load, module_close, module_remove): Use it.
2011 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
2013 * src/main.c (main): Use it.
2015 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2017 * README: Remove references to --enable-changeword, which has been
2018 removed from the code.
2020 2003-06-11 Gary V. Vaughan <gary@gnu.org>
2022 Getting rid of the annoying bug with configure --enable-debug,
2023 which spewed -e: command not found errors. This was an interaction
2024 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
2025 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
2026 branch-1-5) to get the full fix.
2028 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
2029 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
2030 and then use the probed value of $SED.
2031 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
2032 this, it messes up the AC_REQUIRE stack.
2034 2003-06-10 Gary V. Vaughan <gary@gnu.org>
2036 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
2037 the destroy callback.
2038 (m4_arg_destroy): Use the hash address to free the hash node key
2041 2003-06-06 Gary V. Vaughan <gary@gnu.org>
2043 First cut at formal parameters in macros.
2045 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
2046 * m4/xstrzdup.c: New file.
2047 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
2048 associative array of parameter names to details.
2049 (m4_symbol_token): Capture macro names with parameter lists.
2050 (m4_arg_signature_parse): And build an associative array to hang
2051 from the symbol structure to map names to details.
2052 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
2053 m4_hash_resize idiom. Now that we potentially add a little hash
2054 table to many of the entries in the symbol table, added an extra
2055 arg to set the initial size. Changed all callers.
2056 (m4_hash_apply): New function that is basically a generalised
2058 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
2059 all callers to call m4_hash_apply instead.
2060 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
2061 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
2062 m4_arg_signature association that might be attached to the symbol,
2063 * m4/hash.h (m4_hash_apply_func): Replacement type for...
2064 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
2065 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
2067 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
2068 (M4_IS_IDENT): Detect characters that can be safely used in
2070 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
2071 * m4/macro.c: Corrected grammar in some comments. Use `token'
2072 rather than `td' for m4_token variables.
2073 (m4_process_macro): If we find a dollar followed by some
2074 M4_IS_IDENT characters, replace that with the contents of the argv
2075 entry with offset stored in the m4_token_arg associated with the
2076 collected identifier.
2078 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2080 Begin preparations for supporting formal parameters in m4 macros.
2082 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
2083 the details of a formal parameter.
2084 (m4_token): Add an arg_signature member to hold a hash table for
2085 looking up formal parameters.
2086 * m4/input.c: Update more bitrotted comments.
2087 (m4_push_builtin): Initialise arg_signature member.
2088 (init_builtin_token): Copy arg_signature member.
2089 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
2090 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
2092 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
2093 (m4_macro_pushdef, m4_macro_define): ...these, And...
2094 (m4_symbol_token): ...wrapped around this new function, which
2095 vastly simplifies the arguments required by the functions it
2097 Changed all callers.
2099 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2101 * m4/macro.c: Format changes.
2103 2003-06-04 Gary V. Vaughan <gary@gnu.org>
2105 * m4/input.c: Updated various bitrotted comments.
2106 (m4_push_builtin): Just pass the whole m4_token, rather than
2107 extracting all the fields in the caller. This also allows us to
2108 check the token type for consistency.
2109 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
2110 Renamed to builtin_funcs, builtin_peek, builtin_read,
2111 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
2112 the code. Changed all callers.
2113 (struct input_block): Similarly renamed u_m member to u_b, and
2114 changed all callers.
2115 (m4_next_token): Use bzero to initialise the data fields.
2116 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
2118 2003-05-29 Gary V. Vaughan <gary@gnu.org>
2120 These changes were necessary to get m4 to build on my iBook
2121 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
2122 (GCC) 3.1 20020420 (prerelease)":
2124 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
2125 inclusion of module loader headers.
2126 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
2127 * m4/Makefile.am: Ditto.
2128 (libm4_la_LIBADD): Added $(LTLIBINTL).
2129 * m4/utility.c (program_name): Removed declaration in favour of
2130 the one already in error.c!
2131 * m4/m4module.h (program_name): Define to program_invocation_name
2132 when using GNU C library. Use an explicit extern declaration.
2133 (interactive, sync_output, debug_level, hash_table_size)

2143 (m4_current_line, m4_current_diversion, m4_output_current_line):
2144 Don't rely on default, use an explicit extern.
2145 * m4/error.h (error, error_at_line, error_print_progname)
2146 (error_message_count, error_one_per_line): Ditto.
2147 * m4/ltdl.c: Update from CVS libtool.
2149 * commit: Update from CVS cvs-utils.
2151 2002-11-04 Akim Demaille <akim@epita.fr>
2153 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
2155 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
2157 2002-11-04 Akim Demaille <akim@epita.fr>
2159 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
2161 2002-11-04 Akim Demaille <akim@epita.fr>
2163 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
2164 used as `external', and Libtool 1.4.3.
2166 (LTLIBOBJS): Don't play with it.
2168 * Makefile.am (SUBDIRS): Remove intl.
2169 (ACLOCAL_AMFLAGS): Add -I config.
2170 (EXTRA_DIST): Add config/config.rpath.
2173 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
2175 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2177 Preparations for refactoring syntax tables to allow reverse
2178 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
2179 speed of normal lookups in an array of unsigned short.
2181 * m4/input.c (single_quotes, single_comments, use_macro_escape):
2183 * m4/m4private.h (m4__single_quotes, m4__single_comments,
2184 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
2185 is for internal symbols which unavoidably pollute the global
2186 namespace, but are not published APIs.
2187 Adjusted all callers.
2188 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
2189 m4_set_comment, m4_set_syntax, set_syntax_internal,
2190 unset_syntax_attribute): Moved from this file...
2191 * m4/syntax.c: New. ...to this file.
2192 Also added an m4_syntax_exit stub for orthogonality.
2193 * src/main.c (main): Use it.
2194 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
2195 * m4/m4module.h: Reformatting. New prototypes.
2197 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2199 * bootstrap (aclocal_apiversion): The aclocal apiversion is
2200 distinct from the automake release number (in that the apiversion
2201 apparently has no micro-version-component).
2202 (aclocal_apilibdir): Use it.
2204 2002-05-28 Gary V. Vaughan <gary@gnu.org>
2206 * m4/hash.c (m4_hash_resize): New function.
2207 * m4/hash.h: Add prototype.
2208 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
2209 benchmarking to find a good value for, say, autoconf. This is
2210 already a little quicker than before for me.
2212 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
2213 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
2215 * m4/hash.h: Adjust prototypes.
2217 2002-01-22 Akim Demaille <akim@epita.fr>
2219 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
2221 * tests/Makefile.am (package.m4): New.
2222 * tests/atlocal.in: Adjust to CVS Autotest.
2223 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
2224 * configure.ac: LIBOBJ is a forbidden string.
2225 Simplify AM_INIT_AUTOMAKE invocation.
2226 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
2229 2001-10-19 Akim Demaille <akim@epita.fr>
2231 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
2233 2001-10-19 Akim Demaille <akim@epita.fr>
2235 * m4/input.c (m4_next_token): Display where was opened what is
2238 2001-10-19 Akim Demaille <akim@epita.fr>
2240 * m4/macro.c (expand_argument): Display where was opened what is
2243 2001-10-18 Akim Demaille <akim@epita.fr>
2245 * m4/input.c, modules/m4.c: Formatting changes.
2247 2001-10-17 Gary V. Vaughan <gary@gnu.org>
2249 * bootstrap: s/configure.in/configure.ac/
2251 2001-10-16 Gary V. Vaughan <gary@gnu.org>
2253 * m4/symtab.c (m4_symbol_destroy): This function calls
2254 m4_symbol_popdef, which recycles a symbols memory when the last
2255 definition is popped. Since we were passing the address of the
2256 symbol name found in the symbol table, and it was being removed
2257 partway through m4_symbol_destroy() we were referencing freed
2258 memory for the balance of the function. Now we take a copy of the
2259 symbol name tring and use that as a key into the symbol
2260 table... that way if the original symbol name is freed, the copy
2263 2001-10-13 Akim Demaille <akim@epita.fr>
2265 * m4/ltdl.c: Update.
2267 2001-10-13 Akim Demaille <akim@epita.fr>
2269 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
2270 Don't gettextize internal error messages.
2272 2001-10-13 Akim Demaille <akim@epita.fr>
2274 * tests/macros.at (Arity and defn): New failing test.
2275 (Arity, defn, and freeze): New.
2277 Fix `Arity and defn'.
2279 * m4/input.c (m4_push_macro): Don't forget the arity.
2280 * modules/m4.c (defn): Likewise.
2282 2001-10-13 Akim Demaille <akim@epita.fr>
2284 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
2286 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
2287 (Propagation of traceon, Propagation of --trace): this new file.
2289 2001-10-13 Akim Demaille <akim@epita.fr>
2291 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
2292 interface instead of (name, argc...).
2293 Upon failure, specify which argument was guilty.
2296 2001-10-13 Akim Demaille <akim@epita.fr>
2298 * modules/evalparse.c: Save translators' time: don't translate
2299 internal error messages.
2300 (m4_evaluate): Simplify/normalize error messages.
2301 * doc/m4.texinfo (Eval): Adjust.
2303 2001-10-13 Akim Demaille <akim@epita.fr>
2305 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
2306 where no checking is needed.
2307 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
2308 interface instead of (name, argc...).
2310 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
2313 2001-10-13 Akim Demaille <akim@epita.fr>
2315 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
2316 exclude the builtin name from the count.
2317 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
2318 calling ifelse with a single argument is valid.
2319 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
2320 with 1 and 2 args, mostly to strengthen the test suite.
2322 2001-10-13 Akim Demaille <akim@epita.fr>
2324 * m4/output.c (m4_make_diversion, m4_insert_file)
2325 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
2327 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2329 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
2330 since we call these things builtins in the rest of the code!
2332 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
2334 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2336 Rather than forcing each builtin definition to manage its own
2337 argument range checking, tabulate the maxima and minima for all
2338 builtins in each module. This forces us to consider what the
2339 valid ranges for each builtin should be, and moves the checking
2340 code out of each builtin implementation and into the builtin
2341 caller infrastructure.
2343 * m4/m4module.h (struct m4_builtin): Add argument minima and
2345 * m4/m4private.h (struct m4_token): Reflect them here too.
2346 * m4/input.c (struct input_block): ...and here.
2347 (m4_token_copy): New function for token copying.
2348 (init_macro_token): Copy them from a token to the input stack.
2349 (m4_next_token): Don't forget to initialise them for text
2351 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2352 check argument counts before calling the builtin handler.
2353 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2354 (m4_symbol_macro): Likewise.
2355 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2356 parameters. Updated all callers.
2357 (m4_builtin_define): Ditto.
2358 (m4_macro_pushdef, m4_macro_define): Ditto.
2359 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2360 * modules/evalparse.c: Declare argument counts for defined
2361 builtins and remove explicit calls to m4_bad_argc().
2362 * modules/gnu.c: Ditto.
2363 * modules/load.c: Ditto.
2364 * modules/m4.c: Ditto.
2365 * modules/modtest.c: Ditto.
2366 * modules/mpeval.c: Ditto.
2367 * modules/perl.c: Ditto.
2368 * modules/shadow.c: Ditto.
2369 * modules/stdlib.c: Ditto.
2370 * modules/time.c: Ditto.
2373 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2375 The trace semantics now attach the trace bit to a symbol name.
2376 For as long as a traceon(`foo') is active, calls to foo will be
2377 traced regardless of intervening undefines or module unloads.
2378 Fixed the flag propogation issues differently to the fixes
2379 reverted with the last attempt at nailing down trace:
2381 * m4/m4private.h: This file is not visible outside of the m4
2382 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2383 on typing. Updated all clients.
2384 (m4_token): New typedef contains the fields that need to be passed
2385 around with the low level tokeniser.
2386 (m4_token_data): Removed.
2387 (m4_symbol): Now contains the traced flag again.
2388 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2389 the trace bit set. This change is contained entirely within this
2390 module and doesn't leak out into the callers. Updated all
2392 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2393 new fields in m4_token. Updated all clients.
2394 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2395 that `groks_macro_args' and `blind_if_no_args' flags are retained
2396 when defn() results are passed around in m4 code. Updated all
2398 (m4_builtin_define): Ditto.
2399 (m4_macro_pushdef, m4_macro_define): Ditto.
2400 * m4/input.c (struct input_block): Add a flags field to facilitate
2402 (m4_push_macro): ...use it.
2403 (init_macro_token): Retrieve it.
2404 (m4_next_token): Initialise it.
2405 * m4/macro.c (expand_argument): Copy it.
2406 * m4/m4module.h: Adjust.
2407 * tests/builtins.at: Adjust the expected output of the trace
2408 tests to reflect the change in semantics.
2409 * tests/modules.at (modules: trace): Check that unloading a
2410 module which supplies a traced symbol definition doesn't lose te
2413 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2415 * modules/gnu.c (m4_macro_table): Display the timetamp when
2416 expanding __m4_version__.
2418 * configure.ac (--with-modules): Forgot a comma in the
2419 AC_HELP_STRING parameter list.
2421 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2423 * bootstrap: Remove aclocal.m4t when it is no longer required.
2425 2001-10-05 Akim Demaille <akim@epita.fr>
2427 * tests/Makefile.am: Adjust for gnuprog2.
2428 * tests/m4.in: There can be a leading path.
2429 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2430 * tests/testsuite.at: Adjust to the most recent Autotest.
2431 (AT_CHECK_M4_FILTER): Fix and rename as...
2433 * tests/others.at: Use it.
2435 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2436 variable in shell scripts, one uses `$'...
2438 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2440 * configure.ac: `rm -f $m4_getopt_h' was lost.
2442 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2444 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2445 time. Define it for config.h in order to...
2446 * src/main.c (main): ...display the timestamp for --version.
2448 2001-10-04 Akim Demaille <akim@epita.fr>
2450 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2451 previous builtins `regexp' and `patsubst'.
2452 (regexp, patsubst): Use them.
2453 (eregexp, epatsubst): New builtins.
2454 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2455 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2456 (Extensions): More info on REs.
2458 2001-10-04 Akim Demaille <akim@epita.fr>
2460 * modules/modtest.c (init_handler): Consistently output to stderr.
2461 (finish_handler): New.
2462 (test): The `if' is an `assert'.
2463 * tests/modules.at: Adjust.
2465 2001-10-04 Akim Demaille <akim@epita.fr>
2467 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2469 2001-10-01 Akim Demaille <akim@epita.fr>
2471 * tests/generate.awk: Tag the tests with `documentation'.
2472 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2473 Use the make the existing modtest tests more uniform, and complete
2474 the set of possibilities.
2476 2001-10-01 Akim Demaille <akim@epita.fr>
2478 * config/gmp.m4: Consult the user before using GMP: use
2480 * configure.ac: Adjust.
2481 * modules/gmp.c: No protection needed as the module is not built
2484 2001-10-01 Akim Demaille <akim@epita.fr>
2486 * tests/generate.awk: Remove debugging code.
2487 (fatal): Specify the current location.
2489 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2490 * modules/gnu.c, modules/m4.c: Use M4ARG.
2492 2001-10-01 Akim Demaille <akim@epita.fr>
2494 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2495 (m4_regexp_compile): New.
2496 (regexp, patsubst): Use it.
2498 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2500 Reinstate the memory handling improvements from the patch I just
2501 reverted. Relevant ChangeLog entries repeated here:
2503 * m4/module.c (m4_module_remove): New function that holds the core
2504 of the old m4_module_unload.
2505 (m4_module_unload): Use it.
2506 (m4_module_unload_all): When we know the modules will never be
2507 used again (i.e. on exit), free up as much module memory as
2508 possible. There are still some artifacts from resident modules
2509 living inside ltdl.c, but everything else is freed.
2510 * m4/debug.c (m4_debug_exit): Free memory allocated in
2512 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2513 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2514 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2515 * m4/m4module.h: Updated prototypes.
2516 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2517 * m4/hash.h: Updated prototypes.
2518 * src/main.c (main): Use all these new functions to clean up as
2519 much memory as possible before exit.
2521 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2523 Reverted my large patch for removing the old m4_symbol
2524 structure on 2001-09-20. We are still not happy about the way
2525 trace works in conjunction with defn and undefine, and leaving
2526 the reverted patch active prevents us from moving the traced
2527 bit from the definition back to the symbol.
2529 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2531 * configure.in: Moved to...
2532 * configure.ac: ...here. Added a libtool like timestamped
2533 banner, and tidied up the libltdl cruft.
2534 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2535 * modules/Makefile.am (INCLTDL): Removed. This is required
2536 only when libltdl is configured in a subdirectory.
2537 * src/Makefile.am: Ditto.
2538 (LIBADD_DL): No need to add this again, libtool already knows
2539 that libm4.la depends on it.
2540 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2543 * TODO: stackovf.c is basically broken.
2544 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2546 2001-09-28 Akim Demaille <akim@epita.fr>
2548 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2550 2001-09-27 Akim Demaille <akim@epita.fr>
2552 * tests/m4.in: Don't use short options.
2553 Simplify the stderr signature normalization.
2555 2001-09-27 Akim Demaille <akim@epita.fr>
2557 tests/m4 shall be position independent.
2561 * tests/testsuite.at: No args to AT_INIT.
2562 * configure.in, tests/Makefile.am: Adjust.
2564 2001-09-22 Akim Demaille <akim@epita.fr>
2566 Autotest has changed again.
2568 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2569 (package.m4): Remove.
2570 * configure.in: Adjust to LIBADD_GMP.
2572 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2574 * config/gmp.m4 (AC_ARG_WITH): Removed.
2575 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2576 (AC_LIB_GMP): When performing a test compile against libgmp,
2577 include the header gmp.h if possible, and link against -lgmp. If
2578 they both work define USE_GMP.
2579 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2580 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2583 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2585 * m4/evalparse.c: Moved to...
2586 * modules/evalparse.c: ...here. This code is shared between
2587 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2588 the libm4 API with its details. Moderately rewritten to interface
2589 into its clients more simply.
2590 * m4/eval.c: Deleted. Migrated functionality to...
2591 * modules/m4.c: ...here.
2592 (builtin_eval): Implemented in terms of the new interface style.
2593 * modules/mpeval.c (builtin_mpeval): Ditto.
2594 * m4/m4module.h: Removed references to the former m4/eval.c.
2595 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2596 (EXTRA_libm4_la_SOURCES): Deleted.
2597 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2598 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2600 2001-09-20 Akim Demaille <akim@epita.fr>
2602 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2604 By default, use gmp.
2606 * configure.in: Adjust.
2607 Use Automake conditionals for USE_GMP.
2608 Always compute sizeof (long long int).
2609 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2610 before, it was used _only_ if mpeval was not activated.
2611 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2612 (mpeval_la_LIBADD): New macros.
2613 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2615 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2616 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2619 2001-09-20 Akim Demaille <akim@epita.fr>
2621 * tests/Makefile.am (package.m4): New.
2622 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2624 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2626 More cleanup. After the last patch, m4_symbol holds nothing but
2627 the head of a chain of m4_token_data. So I have removed the old
2628 m4_symbol, so that m4_token_data chains are stored directly in the
2629 value cell of a hash table node. But there's more... m4_symbol
2630 was a more natural name for the symbol value cell, and now that it
2631 is gone I have renamed the former m4_token_data structure to
2632 m4_symbol. This change turned out to be a pig to get right, since
2633 the original code didn't need to modify the value cell itself,
2634 since changing the chain happened inside the m4_symbol that used
2635 to be returned -- I had to pass the address of the value cell
2636 across various function calls, incase the head value changed. I
2637 also tightened up the memory management to help me find a nasty
2638 memory corruption bug that took me all night to track down...
2640 * m4/m4private.h (struct m4_symbol): Removed.
2641 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2643 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2644 value cell. Updated all callers.
2645 * m4/symtab.c: Took advantage of the simplification in the data
2646 structures to rewrite a lot of this file more simply. There is
2647 still some room for optimisation here, but we should tackle that
2648 systematically closer to the release.
2650 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2651 revealed. This version is ahead of CVS libtool until I get chance
2652 to flush my changes.
2653 * m4/module.c (m4_module_remove): New function that holds the core
2654 of the old m4_module_unload.
2655 (m4_module_unload): Use it.
2656 (m4_module_unload_all): When we know the modules will never be
2657 used again (i.e. on exit), free up as much module memory as
2658 possible. There are still some artifacts from resident modules
2659 living inside ltdl.c, but everything else is freed.
2660 * m4/debug.c (m4_debug_exit): Free memory allocated in
2662 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2663 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2664 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2665 * m4/m4module.h: Updated prototypes.
2666 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2667 * m4/hash.h: Updated prototypes.
2668 * src/main.c (main): Use all these new functions to clean up as
2669 much memory as possible before exit.
2671 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2673 The `traced' flag needs to be attached to the definition of a
2674 symbol rather than the current symbol containing the definition.
2675 Implementing this showed up some long standing post 1.4 bugs in
2676 flag propogation which I also fixed.
2678 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2679 (struct m4_token_data): And add it back in here.
2680 * m4/input.c (init_macro_token): Propogate the traced flag
2682 * m4/macro.c (expand_argument): Ditto.
2683 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2686 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2688 * m4/m4private.h (struct m4_token_data): Simplified by removing
2689 the redundant `traced' flag, and one level of structure nesting.
2690 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2691 * m4/input.c (init_macro_token): No need to initialise removed
2693 * m4/macro.c (expand_argument): No need to copy it either.
2694 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2697 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2698 dependant on multiple symbols with the same key, so preserving
2699 relative symbol order in each bucket during resizing is no longer
2700 required. The resize function is considerably faster as a result.
2702 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2703 s/m4_symbol_insert/m4_symbol_define/g;
2704 s/m4_builtin_insert/m4_builtin_define/g;
2705 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2707 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2709 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2710 commits, the m4_lookup_symbol dispatch function is split into
2711 specialised functions that must be called directly.
2713 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2714 * m4/symtab.c (m4_lookup_symbol): Removed.
2715 (m4_symbol_builtin, m4_symbol_macro): New functions.
2716 * m4/builtin.c (m4_builtin_define): Split into...
2717 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2718 (m4_macro_define): Split into...
2719 (m4_macro_pushdef, m4_macro_insert): ...these.
2720 * src/main.c (main): Set command line macros from `-D' parameters
2721 using `m4_macro_define'.
2723 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2725 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2726 this from m4_remove_table_reference_symbols().
2727 * m4/m4module.h, m4/module.c: Updated all references.
2729 2001-09-07 Akim Demaille <akim@epita.fr>
2731 * modules/stdlib.c, modules/times.c: Misc cleanups.
2733 2001-09-07 Akim Demaille <akim@epita.fr>
2735 * configure.in: We now need Autoconf 2.52e.
2736 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2737 and `M4_SYMBOL_DELETE'.
2738 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2739 * src/main.c (main): Adjust.
2741 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2743 Fix the obstack.h problem once and for all! At configure time we
2744 can test for a system supplied obstack.h: depending on the
2745 result, we now generate system.h with an #include of the correct
2746 header. As a bonus, I've also added a --with-included-obstack,
2747 incase the user doesn't like the system obstack for some
2748 reason... and also we can test the shipped obstack on a system
2749 that has oe of its own. We also now need to be careful to add
2750 build directories to the include search path, since the generated
2751 system.h will be in the build tree.
2753 * configure.in (AC_CONFIG_FILES): Generate system.h from
2755 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2756 include the system obstack header or the copy shipped with M4.
2757 Allow the user to override configure and force the build to use
2758 the shipped version.
2759 * m4/system-h.in: New file, template for...
2760 * m4/system.h: ...this. Now deleted.
2761 * m4/m4module.h: Include system.h before everything else.
2762 * src/freeze.c: Ditto.
2763 * m4/Makefile.am (dist-hook): Remove generated system.h.
2764 (INCLUDES): Check builddir for generated headers before checking
2766 * modules/Makefile.am (INCLUDES): Ditto.
2767 * src/Makefile.am (INCLUDES): Ditto.
2769 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2771 * TODO: Remove the items that have been addressed already.
2773 2001-09-05 Akim Demaille <akim@epita.fr>
2775 * src/main.c (main): Standardize --version.
2777 2001-09-05 Akim Demaille <akim@epita.fr>
2779 * modules/format.c (format): Have a bigger `str'.
2781 2001-09-05 Akim Demaille <akim@epita.fr>
2783 Rationalize warnings, reporting the macro name as if it were a
2784 program name, and assertions.
2786 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2788 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2790 Use assert for internal errors.
2791 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2793 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2795 * tests/builtins.at (pushpop): Adjust.
2797 2001-09-05 Akim Demaille <akim@epita.fr>
2799 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2802 2001-09-05 Akim Demaille <akim@epita.fr>
2804 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2805 * m4/macro.c, m4/symtab.c: Adjust.
2807 2001-09-05 Akim Demaille <akim@epita.fr>
2809 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2810 (m4_symbol_pop, m4_symbol_del): this.
2811 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2812 (m4_symbol_popdef, m4_symbol_delete): New.
2813 (m4_lookup_symbol): Adjust.
2814 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2816 2001-09-05 Akim Demaille <akim@epita.fr>
2818 * m4/m4module.h (m4_symbol_lookup): Rename as...
2819 (m4_symbol_lookup_t): this.
2821 2001-09-05 Akim Demaille <akim@epita.fr>
2823 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2825 * m4/symtab.c (m4_lookup_symbol): Adjust.
2827 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2829 Bootstrap will now work with Libtool 1.4.1 or higher:
2830 * bootstrap: Remove stale autom4te.cache files when
2832 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2834 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2835 libtool.m4 directly.
2836 Run libtoolize to refresh ltmain.sh.
2837 * config/ltmain.sh: Deleted.
2838 * acinclude.m4: Deleted.
2839 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2841 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2842 implementation for the cvs impaired libtool user.
2844 2001-09-03 Akim Demaille <akim@epita.fr>
2846 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2848 Avoid using `default' in switch, as it hides useful compiler
2849 warnings when a case is forgotten.
2851 2001-09-03 Akim Demaille <akim@epita.fr>
2853 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2854 is no such thing as `WITH_MODULES'.
2856 2001-09-03 Akim Demaille <akim@epita.fr>
2858 Improve the test suite's selfcontainedness.
2860 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2861 (Include, Undivert): Tag the other input files.
2862 * tests/generate.awk: Catch `@comment file:'.
2863 `-I $src' is no longer needed.
2864 `next' is really like `return': the rest is skipped.
2865 Adjust to `input.m4'.
2866 (fatal): New function.
2867 * tests/foo, tests/incl.m4: Remove.
2869 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2871 The shadowing mechanism and, infact, the whole symbol table
2872 implementation was creaking under the weight of the features piled
2873 on top of it. We now have a separate hash table module which will
2874 dynamically resize to keep symbol density withing good performace
2875 limits, and a new symtab module layered above it. Symbol lookups
2876 are now marginally more efficient (since the shadowed flag is no
2877 longer required) and symbol removal, such as on module unload, is
2878 considerably faster due to a reorganisation of the data structures
2881 * src/main.c (main): Don't mention `-H'.
2882 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2885 * m4/hash.c: New generalised dynamic hash table data structure
2887 * m4/hash.h: Public interface.
2888 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2889 (libm4_la_SOURCES): Add hash.c.
2890 * m4/symtab.c: More or less rewritten from scratch, within the
2891 bounds of the previous API.
2892 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
2893 call. Updated all callers.
2894 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
2895 declarations to reflect API changes.
2896 (M4INIT): Generate a declaration too, to avoid the warning with
2897 --enable-debug builds.
2900 * m4/utility.c (hash_table_size): Removed.
2901 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
2902 names, which are then looked up by builtin_dumpdef() as necessary.
2903 This implies a small speedup in builtin_symbols(), which discarded
2904 all of the symbol info under the old call.
2905 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
2906 shadowing is implicit in respect to the new data structures.
2907 symbol names are no longer duplicated here, they are stored in the
2908 key field of the hash table.
2909 Moved macro_args and blind_no_args...
2910 (m4_token_data): ...to here.
2911 m4/macro.c (expand_macro): Added a name argument since the symbol
2912 name is no longer copied into each struct m4_symbol. Modified all
2914 (collect_arguments): Ditto.
2915 * modules/m4.c (set_trace): Ditto.
2916 * modules/gnu.c (builtin_symbols): Updated.
2917 * src/freeze.c (produce_symbol_dump): Much improved in light of
2918 the improved symbol table layout.
2920 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2922 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
2924 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
2925 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
2926 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
2927 SYMBOL_HANDLE): Ditto.
2928 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
2929 modules/gnu.c, modules/m4.c, src/freeze.c,
2930 src/main.c: Updated all references.
2932 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
2933 Automake 1.5 chokes on dynamic source file lists, Besides, it is
2934 already listed in m4_LDADD... how did that ever used to work?
2935 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
2937 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2938 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
2940 * tests/m4: Don't call the m4 wrapper script with libtool, it
2941 works fine all by itself.
2943 2001-08-30 Gary V. Vaughan <gary@gnu.org>
2945 The experimental `changeword' feature never took off, and has
2946 no obvious advantages over `changesyntax' to compensate the
2947 enormous speed penalty it carries:
2948 * configure.in (ENABLE_CHANGEWORD): Removed.
2949 * m4/m4module.h (m4_set_word_regexp): Removed.
2950 * m4/m4private.h (m4_token_data): Removed original_text field.
2951 * m4/utility.c (m4_token_data_orig_text): Removed.
2952 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
2953 * m4/macro.c: Ditto.
2954 * src/main.c: Ditto.
2955 * modules/Makefile.am (changeword.la): Removed.
2956 * modules/changeword.c: File removed.
2957 * doc/m4.texinfo: References to changeword and --word-regexp
2959 * po/POTFILES.in: modules/changeword.c removed.
2960 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
2961 * tests/builtins.at (changeword): Test removed.
2963 2001-08-30 Akim Demaille <akim@epita.fr>
2965 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
2966 This also help having a single list of m4 files: in
2968 * config/Makefile.am (STANDARD_MACROS): Rename as...
2969 (ACLOCAL_MACROS): this.
2970 (list-standard-macros): Remove.
2973 2001-08-29 Gary V. Vaughan <gary@gnu.org>
2975 In an attempt to moderate my egomania...
2976 * tests/modules.at: Remove attributions.
2978 * tests/generate.awk: When making substitutions to "@&t@", either
2979 "&" or "\&" in the substitution string argument to gsub refer back
2980 to the matched text. "@\\&t@" seems to work though, Tests 43 and
2983 2001-08-29 Akim Demaille <akim@epita.fr>
2985 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
2986 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
2987 (sync-lines, trace, translit, undivert, wrap): Move to...
2988 * tests/builtins.at: this new file.
2989 * tests/others.at (Discard comments, import-environment): Move to...
2990 * tests/options.at: this new file.
2992 2001-08-29 Akim Demaille <akim@epita.fr>
2994 * tests/others.at (Freezing modules)
2995 (--module-directory: absolute path, modpath2, modpath3)
2996 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
2997 * tests/modules.at: here, new file.
2998 * tests/others.at, tests/generate.awk: Add a banner.
2999 * tests/testsuite.at: Adjust.
3000 (AT_CHECK_M4_FILTER): New, but unused.
3002 2001-08-29 Akim Demaille <akim@epita.fr>
3004 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
3006 * tests/others.at (wrap): Inline wrap.m4.
3007 (shadow): Inline shadow.m4.
3008 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
3009 * tests/m4: Simplify.
3011 2001-08-29 Akim Demaille <akim@epita.fr>
3013 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
3016 2001-08-29 Akim Demaille <akim@epita.fr>
3018 * tests/generate.awk (normalize): s/@__@/@&t@/.
3020 2001-08-28 Akim Demaille <akim@epita.fr>
3022 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
3024 2001-08-28 Gary V. Vaughan <gary@gnu.org>
3026 * bootstrap (generate.awk): Generate test cases with new script.
3028 2001-08-27 Akim Demaille <akim@epita.fr>
3030 * tests/Makefile.am (installcheck-local): Don't use
3031 `dc_install_base' which is not visible here, but `exec_prefix'
3032 which is clearly the RT anyway.
3033 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
3034 related to testing a now installed m4.
3035 * tests/m4: Do it here.
3037 2001-08-27 Akim Demaille <akim@epita.fr>
3039 * tests/others.at (indir): Formatting change.
3041 2001-08-27 Akim Demaille <akim@epita.fr>
3043 * tests/Makefile.am (installcheck-local): New.
3044 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
3046 Prefer options over envvars.
3047 * src/main.c (main): First bug caught by the test suite (yeah!):
3048 --batch lacked a `break' which resulted in an accidental
3049 invocation of --discard-comments.
3051 2001-08-27 Akim Demaille <akim@epita.fr>
3053 * tests/others.at (capitalize, changeword, comments, ddivert)
3054 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
3055 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
3056 (sysv-args, trace, translit, undivert): Don't rely on files in
3057 examples/: AT_DATA them.
3059 2001-08-27 Akim Demaille <akim@epita.fr>
3061 Let the test suite use a wrapper around the not installed m4 to
3062 pretend it is (installed).
3064 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
3065 such a way that m4 does not process them.
3066 * configure.in: The package name seems to be `m4', not `M4'.
3068 * tests/atlocal.in (at_package, M4): Remove.
3069 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
3071 2001-08-27 Akim Demaille <akim@epita.fr>
3073 * tests/Makefile.am (CLEANFILES): Remove.
3074 (DISTCLEANFILES, clean-local): New.
3075 * examples/mktests.sh: Remove.
3077 2001-08-27 Akim Demaille <akim@epita.fr>
3079 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
3080 Don't use aclocal: it's written by hand.
3081 * aclocal.m4: m4_include all the files instead of being built by
3083 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
3084 until it reads the traces by itself.
3085 * configure.in: Require Autoconf 2.42c as we are now using
3086 AC_CONFIG_TESTDIR instead of AT_CONFIG.
3087 Catch unexpanded `jm_' macros.
3088 * config/atconfig.m4: Remove.
3089 * config/error.m4: new.
3090 * config/Makefile.am: Ship the files included by aclocal.m4.
3091 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
3092 (TESTSUITE_AT): this, to please Automake.
3093 (TESTSUITE): This target uses autotest/autotest.m4, not
3094 autotest/general.m4.
3095 * tests/testsuite.at: Prereq Autotest 2.52c.
3096 * examples/Makefile.am (pkgdata_DATA): Rename as...

3098 * doc/Makefile.am (man_MANS): Rename as...
3099 (dist_man_mans): this.
3101 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3103 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
3104 Robert Collins, building on Cygwin no longer requires Windows
3105 import and export symbol decorations.
3106 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
3107 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
3108 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3109 * m4/error.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

3111 * m4/macro.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3112 * m4/output.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3113 * m4/utilty.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3114 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3115 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
3117 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
3118 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
3120 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3122 Ansify the source. Previously we had a mix, where my code was
3123 in a K&R compatible style, and the preexisting code was in ANSI
3124 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
3125 and now the code base is much cleaner.
3127 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
3128 VOID macro and all users.
3129 * m4/m4module.h: Ansify function prototypes and headers.
3130 * m4/builtin.c: Ditto.
3131 * m4/evalparse.c: Ditto.
3132 * m4/input.c: Ditto.
3133 * m4/macro.c: Ditto.
3134 * m4/module.c: Ditto.
3135 * m4/output.c: Ditto.
3137 * m4/symtab.c: Ditto.
3138 * m4/utility.c: Ditto.
3139 * modules/format.c: Ditto.
3140 * modules/gnu.c: Ditto.
3141 * modules/m4.c: Ditto.
3142 * modules/mpeval.c: Ditto.
3143 * src/freeze.c: Ditto.
3145 * src/main.c: Ditto.
3147 2001-08-20 Akim Demaille <akim@epita.fr>
3149 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
3150 generated with stock 2.52.
3152 2001-08-20 Akim Demaille <akim@epita.fr>
3154 * config/atconfig.m4: New, until part of Autoconf per se.
3155 * configure.in (AT_CONFIG): Use it.
3157 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
3158 * tests/atlocal.in: New.
3159 * tests/generate.awk: For the time being, the empty quadrigraph is
3161 * tests/others.at (changeword, gmp): Check the configuration
3162 variable against `yes'.
3163 * tests/testsuite.at (dnl): Allow it, as it's used all over the
3166 2001-08-20 Akim Demaille <akim@epita.fr>
3168 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
3169 * modules/m4.c (undivert): Disable the possibility of undiverting
3170 several files at once: it is not documented, it is inconsistent
3171 with the other macros, it can be straightforwardly mocked by
3172 several invocations, and most importantly, it prevents the
3173 possibility of other kinds of extension.

3184 2001-08-20 Akim Demaille <akim@epita.fr>
3186 Use sprintf, not ecft and friends since it is standard, portable,
3187 simplifies the code, and since the latter is even deprecated

3397 (M4FINISH_HANDLER): And similarly for finish functions.
3398 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
3399 -- Add indirection to the CONC macro so that arguments are
3401 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
3402 * modules/shadow.c (m4_init_module): Ditto.

3410 (m4_module_data): ...structure without all the wrapper fields.

3414 instead of the old module argument.
3415 (m4_builtin_table_install): Ditto.
3416 * modules/load.c (m4_resident_module): Removed. This is no
3417 longer implemented as a magic symbol...

3435 various tokens that are passed between functions.
3436 (struct m4_symbol): Removed the module field. The
3437 module association does not belong with the symbol...
3438 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
3439 that the module implementation code is from. Added a handle
3441 (m4_push_macro): Add a `handle' argument. Changed all callers.
3442 (init_macro_token): Set the `handle' field for the
3444 * m4/macro.c (expand_argument): Copy the new handle field during
3446 * modules/m4.c (macro_install): Use the new handle field to
3447 optimise the search for the correct builtin structure, and pass
3448 the handle details to m4_builtin_define.
3450 2001-08-15 Akim Demaille <akim@epita.fr>
3452 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
3453 when creating `m4/obstack.h'.
3454 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
3456 * tests/defs: Make them absolute.
3457 (CDPATH) Neutralize.
3458 * tests/gethem: Use them.
3460 2001-08-14 Gary V. Vaughan <gary@gnu.org>
3462 * config/ltmain.sh: Doh! Import again for a quoting fix that
3463 prevented any regression test from passing.
3465 * m4/m4module.h (obstack.h): Choose between installed version
3466 and shipped version based on configure tests.
3467 * src/freeze.c (obstack.h): Ditto.

3475 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.

3477 shell variable m4_cv_func_obstack_h.
3478 * tests/defs (M4): Be more careful about relative path to libtool
3479 script and m4 binary by using $srcdir.
3481 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3482 optargs to the existing libltdl search path.
3483 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
3484 * m4/ltdl.c: Updated.

3490 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3491 interactive mode off.
3493 2001-08-10 Akim Demaille <akim@epita.fr>
3495 * configure.in: Require Autoconf 2.52.
3496 (AC_ARG_PROGRAM): Remove, handled by Automake.
3497 (m4_getopt): Rename as...
3498 (m4_getopt_h): this.

3501 * config/gnu-obstack.m4: Require Autoconf 2.52.
3502 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

3512 * src/main.c (main): Fix improper uses of error (missing format
3515 2001-08-07 Akim Demaille <akim@epita.fr>
3517 Improve `make distcheck'.
3519 * configure.in: Be sure to be able to run `mkconfig.sh' when src

3522 * doc/m4.texinfo (Include): Add missing blank.

3554 feature to mark modules as resident if they export
3555 `m4_resident_module' as TRUE.
3556 (m4_module_unload): Do not remove resident modules, and take care
3557 with symbol insertion and deletion with resident modules.
3558 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3559 use resident modules feature.
3561 2000-11-30 Gary V. Vaughan <gary@gnu.org>
3563 * TODO: Updated. Removed some cruft that has since been fixed
3564 or implemented. Added some more entries.

3622 Move the implementation of GMP support for the mpeval() builtin
3623 into a loadable module that depends on libgmp. mpeval() and
3624 eval() share a common parser, now in m4/evalparser.c; the code
3625 in m4/numb.c and m4/numb.h is now physically split between
3626 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3627 mpeval() backend), rather than being differentiated by cpp
3628 macros and multiple inclusion. The mpeval module is always
3629 built but will generate an diagnostic if it is used from an
3630 installation that didn't link in the gmp library.
3631 * modules/Makefile.am: build and install the new mpeval module.
3632 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3633 and m4/numb.h that are required for gmp support in mpeval().
3634 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3635 * m4/evalmp.c: Removed.
3636 * m4/m4module.h: Removed conditional prototype for
3638 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3639 and m4/numb.h that do not rely on gmp.
3640 * m4/evalparse.c: New file, contains the shared parts of the
3641 eval() and evalmp() parser implementations, and is no longer
3642 unencumbered by cpp magic to uncover the right parts.
3643 * m4/numb.h: Removed. It's former contents are split between
3644 m4/eval.c and modules/mpeval.c.
3647 * tests/other-tests/changeword.test: New test. Rudimentary
3648 testing of changeword builtin runs only if --wnable-changeword
3649 was used at configure time.
3650 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3651 alternation correctly. Split into two expressions to compensate.
3652 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3653 * modules/Makefile.am: Build changeword module.
3654 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3655 only when --enable-changeword was passed to configure.
3656 (builtin_changeword): If --enable-changeword was not used, then
3657 report that changeword() builtin has no support in m4 binary.
3659 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3661 * src/main.c (main): Fixed a particularly nasty bug is
3662 user_search_path setting -- the -M flag processing must be
3663 extremely careful with search path ordering, or else the default
3664 installed module directory (possibly containing modules from a
3665 previous release) is placed earlier in the search path than any -M
3666 arguments (which are relied upon to load uninstalled modules with
3667 most of the tests in the regresion suite).
3669 * modules/load.c (builtin_load): Nasty hack to prevent adding
3670 symbols to symtab again if a module is loaded more than once.
3671 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3673 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3674 possible NULL pointer dereference.
3676 * m4/module.c (m4_module_find_by_modname): Renamed from
3677 m4_module_modname_find. Fixed all references.
3678 (m4_module_find_by_builtin): New function.
3680 * modules/modfreeze.test: load the `load' module with each
3682 * src/freeze.c (produce_frozen_state): Simplified in light of
3683 module field in m4_symbol. Allow a third argument for text macros
3684 to name the originating module.
3685 (reload_frozen_state): ditto.
3686 * m4/m4module.h: Fixup prototypes.
3687 * m4/builtin.h (m4_builtin_define): Add a module argument so
3688 that symbols can be registered against the defining module.
3689 (m4_macro_define): ditto.
3690 * m4/m4private.h (m4_symbol): Make the module field const to save
3691 on casting in the rest of the code.
3692 (SYMBOL_MODULE): New macro.
3694 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3695 symbol reference maintenance bugs when removing a symbol from the
3698 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3700 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3702 * configure.in (m4_cv_func_obstack): A better check for whether
3703 libc has an obstack implementation.
3704 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3706 * configure.in (--with-modules): Changed semantics. This
3707 option is now used to list modules to be preopened.
3708 * src/m4.h: #include "ltdl.h" unconditionally.
3709 * src/main.c: Removed all dependencies on WITH_MODULES.
3710 * src/freeze.c: ditto.
3711 * modules/Makefile.am: ditto.
3712 * m4/m4.c (builtin_m4exit): ditto.
3713 * modules/modpath1.test: ditto.
3714 * modules/modpath2.test: ditto.
3715 * modules/modpath3.test: ditto.
3716 * modules/modpath4.test: ditto.
3717 * modules/modtest.test: ditto.
3718 * modules/shadow.test: ditto.
3719 * modules/unload.test: ditto.
3721 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3722 comes up on demand in LTLIBOBJS now.
3723 * configure.in (getopt_long): Creating and relying on a link for
3724 getopt.h on hosts with no getopt_long() of thier own works
3725 correctly now. This is necessary so that callers of getopt_long()
3726 can simply `#include <getopt.h>': the naive way of doing this
3727 would end up using our own getopt.h and the installed
3728 getopt_long(), which is asking for trouble!
3729 (obstack_init): A similar argument applies to obstack.h and
3732 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3733 On Solaris-2.5 (at least) the native dlopen implementation
3734 gets confused about m4.o when looking for module "m4". This
3735 version always looks for .la an .$lib_ext suffixed names first
3736 to work around the problem. Sigh.
3738 * po/POTFILES.in: Take account of these file movements.
3739 * src/Makefile.am (m4_SOURCES): removed eval.c.
3740 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3741 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3742 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3743 * modules/m4.c (builtin_eval): Use m4_evaluate().
3744 * m4/eval.c: Moved here from src/eval.c to facilitate
3745 implementation of eval() builtin as part of the `m4' loadable
3747 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3748 * m4/numb.c: Moved here from src/numb.c, since it is #included
3749 into eval.c at compile time.
3750 * m4/m4module.h (m4_evaluate): Added prototype.
3751 * src/m4.h (evaluate): Removed prototype.
3753 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3755 * modules/perl.c (builtin_perleval): Use PL_na for
3756 compatibility with perl-5.6.
3758 * src/main.c (main): It is now safe to
3759 ``m4_module_install("m4")'', without tripping over the m4
3761 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3762 versions having fixed the insidious module search order bug.
3764 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3765 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3767 * configure.in: Figure out whether to use the installed
3768 getopt.h or the supplied one.
3769 * src/Makefile.am: ditto.
3771 * po/POTFILES.in: List files in their new positions.
3773 * config/ltmain.sh: This needs to be checked in to match the
3774 libtool macros copied to acinclude.m4 (until a released
3775 libtool copes with m4's needs).
3776 * bootstrap: Run gettextize.
3778 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3780 * AUTHORS: Added my details.
3783 * bootstrap: temporary update until released libtool catches up.
3785 * All files: Use new GNU GPL copyright blurb with current contact

3792 other autoconfiscated packages.
3794 * configure.in (M4_AC_CHECK_DEBUGGING): Use it.
3795 * config/debug.m4: New file implementing configure macros to add
3796 suitable debug flags to the compiler invocation.

3818 normally -- i.e. without the -G option.
3819 * modules/gnu.c: New file implementing a new loadable module wuth
3820 definitions for all the gnu extension builtins.
3821 * modules/format.c: Moved here from src/format.c. Now included
3824 * src/main.c (main): Load the traditional module if m4 was
3825 started in `no_gnu_extensions' mode.
3826 * modules/traditional.c: New file implementing the ``unix'' macro,
3827 required when m4 is executed in traditional mode, as a loadable
3830 * src/main.c: Renamed from m4.c to avoid confusion with
3832 (main): Always load the m4 module.
3833 * modules/m4.c: New file implementing a new loadable module with
3834 definitions for all m4 builtins that are not gnu extensions.

3840 the migration of all builtin implementations to loadable modules.
3841 * m4/macro.c: Moved this file here from the src directory,
3842 renaming all exported symbols to use the prefix ``m4_''.

3845 * m4/symtab.c: ditto.
3846 * m4/debug.c: ditto.
3847 * m4/input.c: ditto.
3848 * m4/output.c: ditto.
3850 * m4/ltdl.h, m4/ltdl.c: ditto.
3851 * m4/utility.c: Odd functions moved here from files in the src
3852 directory to facilitate builtin migration.
3854 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3856 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3857 error message, to make translators' jobs a little easier.
3858 (builtin_builtin): ditto.
3859 (builtin_traceon): ditto.
3860 (builtin_traceoff): ditto.
3861 Reported by Akim Demaille <akim@epita.fr>

3864 pkgincludedir instead.

3887 makeinfo calculates them for us, and to make any future
3888 reorganisation easier.
3889 (Frozen files): Document format version 2.
3890 `V' now takes argument `2'.

4033 initialised from here when loading a frozen file.
4035 * src/builtin.c: Much improved macro definition style.
4036 * src/m4private.h: Internal structures for m4_builtin and

4105 increment serial number.

4109 it doesn't rely on the src directory.

4163 * src/ltdl.c: Use access() to abort doomed module load attempts
4164 if module file does not exist.
4166 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
4167 getopt1.o will already be used if appropriate, so I moved getopt.c
4168 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
4170 * modules/modpath1.test: Use correct filename in header line.
4171 * modules/modpath2.test: ditto.
4172 * modules/modpath3.test: ditto.
4173 * modules/modpath4.test: ditto.
4175 Without these changes lt_dlopen("test") attempts to
4176 LoadLibrary("/bin/test") on Windows, which although harmless
4177 generates a spurious error message which spoils most of the tests:
4178 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
4179 (TESTS): s/test.test /modtest.test /
4180 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
4181 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
4182 * modules/modpath1.test: s/test.m4 /modtest.m4 /
4183 * modules/modpath2.test: ditto.
4184 * modules/modpath4.test: ditto.
4185 * modules/modpath3.test: s/-m test /-m modtest /
4186 * modules/shadow.m4: use {un,}loadmodule(`modtest').
4188 2000-01-16 Gary V. Vaughan <gary@gnu.org>
4190 * src/ltdl.c (find_file): Updated to new version with fixed memory
4191 allocation bug in `next'.
4192 * src/ltdl.h: updated to match.
4194 * modules/Makefile.am: Cleaned up and reordered.
4196 2000-01-16 René Seindal <rene@seindal.dk>
4198 * modules/Makefile.am (TESTS): New tests for the module system.
4200 * modules/*.test: New files.
4202 * src/m4.c (main): Added call to module_init().
4203 Treats -M and -m as the arguments -D -U and -t, ie deferred.
4205 * src/m4.h: Added declaration of module_init().
4207 * src/module.c (module_init): No longer static
4209 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
4210 Added to shut up automake about non standard libtool library
4213 * src/module.c: Disabled DEBUG by default.
4215 * modules/README: Changed example from unload.m4 to shadow.m4
4217 * modules/shadow.m4: Renamed from unload.m4
4219 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
4221 * src/m4.c (main): Functionality for -m and -M were reversed.
4224 2000-01-12 Gary V. Vaughan <gary@gnu.org>
4226 * doc/help2man.pl: updated to version 1.020.
4228 * lib/COPYING.LIB: updated to version 2.1.
4230 * lib/m4module.h: restructure the M4_SCOPE code to work when
4231 creating a dll which links with libm4.la and both DLL_EXPORT
4232 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
4235 2000-01-11 Gary V. Vaughan <gary@gnu.org>
4237 Merged the following changes from my tree:
4239 1999-06-15 Gary V. Vaughan <gary@gnu.org>
4241 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
4242 ported to compile shared libs.
4244 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
4245 use `__declspec(dllimport)' when linking libm4.la on win32.
4246 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
4248 * configure.in (M4OBJS): Discover whether we need the shipped
4249 implementation of getopt_long.
4250 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
4251 main binary here, as opposed to the module library in lib/libm4.la.
4253 1999-06-14 Gary V. Vaughan <gary@gnu.org>
4255 * modules/README: Updated to describe the improved libltdl based
4257 * README (cygwin): Added some compilation notes for building m4
4258 correctly under cygwin.
4259 * TODO: Cleaned out the entries for the module system since they
4260 are now implemented.
4262 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
4263 all instances of __P with M4_PARAMS.
4265 * lib/getdate.h: removed unreferenced file.
4267 * lib/m4private.h: New file to define the private interface to the
4268 token_data struct, which must be shared between m4module.c, and
4269 builtin.c but not exported to modules built from the installed
4270 m4module.h since it's size changes depending on compile time
4273 * src/m4.h: Lots of stuff moved to lib/m4module.h.
4275 * lib/m4module.h: New file to define the interface available when
4276 compiling m4 modules.
4277 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
4278 necessary for module compilation into this new file.
4280 * lib/Makefile.am (include_HEADERS): install headers (renamed to
4281 avoid nameclash with other system headers) necessary for compiling
4283 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
4284 so that modules can include the (renamed) installed headers and
4285 be guaranteed a matching implementation.
4286 * lib/m4error.h: renamed from error.h.
4287 * lib/m4obstack.h: renamed from obstack.h.
4288 * lib/m4regex.h: renamed from regex.h.
4289 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
4290 implementation, simply include the shipped version
4291 unconditionally, otherwise it is hard for a module to know
4292 whether the m4obstack.h header it is using matches the
4293 implementation it ends up linking against.
4294 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
4297 1999-05-18 Gary V. Vaughan <gary@gnu.org>
4299 * examples/misc.test: Don't run this test on machines which don't
4300 have a root user in /etc/passwd (e.g. cygwin).
4302 * tests/get-them (/^@example$/): Error messages might have a
4303 ``.exe'' suffix to the program name, or else use the libtool
4304 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
4305 of these cases are now catered for when comparing error messages
4307 * tests/other-tests/*.test: ditto.
4308 * examples/*.test: ditto.
4310 * tests/defs (M4): use libtool execute mode.
4311 * examples/defs (M4): ditto.
4313 * tests/get-them (END): explicitly close any open file.
4314 (printthem): In a regular expression, '{' is the start of a repeat
4315 count! Use `[{]' for a literal open brace.
4316 (/^@node /): Don't use substr on a string shorter than the trim
4319 1999-05-17 Gary V. Vaughan <gary@gnu.org>
4321 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
4323 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
4325 2000-01-10 Andreas Schwab <schwab@suse.de>
4327 * tests/other-tests/gmp.test: Find config.sh in build directory.
4329 * configure.in: Find tests/mkconfig.sh in $srcdir.
4331 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
4332 <signal.h> (for SUS2 compliant systems).
4334 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
4337 2000-01-10 René Seindal <rene@seindal.dk>
4341 * TODO, NEWS: Cleaned up and updated.
4343 * src/m4.c (main): New variable exit_status for exit status in
4344 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4345 file cannot be read instead of EXIT_SUCCESS.
4347 * src/builtin.c (m4_indir): Changed error message to help
4348 translators (from Akim Demaille <demaille@inf.enst.fr>).
4350 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4353 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4356 * src/input.c (match_input): Reordering of code, to avoid multiple
4357 calls to push_string_init() from obstack_grow(), which can happen
4358 with some compilers (found and fixed by James Bonfield
4359 <jkb@mrc-lmb.cam.ac.uk>).
4361 * src/stackovf.c: Added prototypes for ultrix.
4362 (setup_stackovf_trap): Added __P to cast.
4363 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4365 2000-01-09 René Seindal <rene@seindal.dk>
4367 * doc/m4.texinfo (Changequote): Added comment about changing
4368 quotes when the old quote is a part of the new.
4370 * src/builtin.c (expand_ranges): Added break after trailing dash.
4371 This caused misbehavious on some systems (found and fixed by Akim
4372 Demaille <demaille@inf.enst.fr>).
4374 * AUTHORS: Thomas Tanner included
4376 * acconfig.h: Added entry for ss_sp (see below).
4378 * configure.in (use_stackovf): Added check for stack_t with member
4379 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
4380 <eggert@twinsun.com>).
4382 * doc/m4.texinfo (Frozen files): Added a simpler example for
4383 generating frozen files from several input files.
4385 1999-11-14 Paul Eggert <eggert@twinsun.com>
4387 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
4388 lib/regex.c, lib/xmalloc.c.
4390 1999-11-10 René Seindal <rene@seindal.dk>
4392 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4394 * src/module.c: reindented.
4395 (module_load): return if this is a repeated load of same module.
4396 (module_init): slight change of logic to avoid repeated
4397 initialisation debug messages.
4399 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4400 in the distribution.
4402 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
4403 automake warnings about missing lib prefix.
4404 (time_la_LDFLAGS): ditto
4405 (stdlib_la_LDFLAGS): ditto
4407 1999-11-10 Paul Eggert <eggert@twinsun.com>
4409 * src/m4.h: Include error.h, since our macros use error.
4410 * src/m4.c: Don't need to include error.h.
4412 1999-11-09 Paul Eggert <eggert@twinsun.com>
4414 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4415 and zero, as Solaris 7 cc does.
4416 (bcopy): Remove macro; no longer needed with new obstack.h.
4418 * src/output.c (freeze_diversions): Don't assume that a
4419 diversion size can fit in `int'. Check for diversion file
4420 size too large to be printed with `unsigned long'.
4422 * src/Makefile.am (CFLAGS): Omit -Wall.
4424 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4426 * src/debug.c (trace_format):
4427 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.
4429 * src/freeze.c (produce_frozen_state):
4430 Don't assume string lengths fit in int.
4432 1999-10-13 René Seindal <rene@seindal.dk>
4434 * configure.in (ALL_LINGUAS): Added Greek translation (el).
4435 (ALL_LINGUAS): Added Czech translation (cs).
4437 1999-03-30 Gary V. Vaughan <gary@gnu.org>
4439 * src/builtin.c: moved module loading functions into...
4440 * src/module.c: entirely new implementation using libltdl.
4441 * po/POTFILES.in: added src/module.c.
4442 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
4443 are modules, not linktime libraries.
4444 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4445 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4446 avoidance on exported symbols.
4447 * modules/test.c (m4_macro_table, m4_init_module,
4448 m4_finish_module): ditto.
4449 * modules/time.c (m4_macro_table): ditto.
4451 * modules/time2.m4: new file which requires command line loading
4453 * src/m4.c (--load-module): dynamically load named runtime module
4454 into running executable before reading the source.
4455 (--module-directory): prepend a directory to the module search
4457 (module_init()): Do this the first time we load a module instead;
4458 if the module subsystem is broken normal m4 scripts can still run.
4459 * src/m4.h (install_builtin_table): is now exported.
4461 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4463 * src/module.c: removed. No longer required.
4464 * po/POTFILES.in: removed src/module.c.
4466 * Makefile.am (MAINTAINERCLEANFILES): Remove all the files that
4467 the bootstrap script can recreate.
4468 * acm4/Makefile.am (MAINTAINERCLEANFILES): ditto.
4469 * doc/Makefile.am (MAINTAINERCLEANFILES): ditto.
4470 * examples/Makefile.am (MAINTAINERCLEANFILES): ditto.
4471 * lib/Makefile.am (MAINTAINERCLEANFILES): ditto.
4472 (AUTOMAKE_OPTIONS): reduced strictness to allow COPYING.LIB.
4473 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
4474 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4475 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
4477 * acinclude.m4: removed. `aclocal -I acm4' handles this much
4479 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4480 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4481 the installed gettext.m4 file when running aclocal.
4483 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4485 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
4486 distinguish this from the last prerelease.
4487 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
4488 in its own subdirectory.
4490 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
4491 lib prefix on a module" feature.
4492 (LDFLAGS): Added `-module -avoid-version' flags to build
4493 versionless module libraries.
4494 * src/builtin.c (m4_load_module): use libltdl.
4495 (module_unload_all): use libltdl.
4496 * src/m4.c (module_init): initialise module loading on demand for
4497 better diagnostics, and so that m4 will still work even if
4498 the module code is broken.
4499 * src/m4.h (module_init): removed. No longer relevant.
4500 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4501 exported symbols for compatibility with dlpreopening.
4502 * modules/test.c (m4_macro_table, m4_init_module,
4503 m4_finish_module): ditto.
4504 * modules/time.c (m4_macro_table): ditto.
4506 * bootstrap: New file. Runs all the autoutils in the right order
4507 after a fresh checkout, or a make maintainer-clean.
4509 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4511 * src/builtin.c (dump_symbols): New function, factoring common
4512 content of m4_dumpdef and m4_symbols.
4513 (m4_dumpdef): Use it.
4514 (m4_symbols): New function, implementing `symbols'. Use it.
4515 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4516 file compile with modern makeinfo.
4517 (Symbols): New node, documenting symbols.
4518 (direntry): Modernize.
4520 1998-12-11 René Seindal <rene@seindal.dk>
4522 * src/builtin.c (predefined_tab): New predefined macros
4523 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
4524 configure time options.
4526 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4528 * src/module.c (module_try_load): Don't try to be clever and
4529 overwrite argument string. Instead allocate all constructed
4530 strings locally, since they can have arbitrary lengths. Make
4531 arguments pointers to const.
4532 (module_search): Simplify due to above change.
4534 1998-11-29 René Seindal <rene@seindal.dk>
4538 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
4540 * tests/other-tests/import-environment.{m4,test}: New test.
4542 * tests/other-tests/discard-comments.{m4,test}: New test.
4544 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
4546 * src/m4.c (main): New option -c --discard-comments.
4547 New global variable discard_comments.
4549 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
4550 discarded, ie never returned from next_token().
4551 Added declaration of discard_comments.
4553 * src/input.c (next_token): Now loops until token type is not
4554 TOKEN_NONE. Comments are now given this type when comments should
4557 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
4560 1998-11-28 René Seindal <rene@seindal.dk>
4562 * src/m4.c (main): New option --import-environment (no single
4565 * When configured with --with-gmp both the normal (fast) eval()
4566 and the gmp aware mpeval() are defined. To restore previous
4567 bahaviour use "define(`eval', defn(`mpeval'))".
4569 * tests/other-tests/gmp.m4: Changed to use mpeval().
4571 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4572 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4574 * src/eval.c: Now includes "numb.c" directly. Everything in this
4575 file must by static, except evaluate(), which is changed to
4576 mp_evaluate() if USE_GMP in force.
4578 * src/numb.c: Changed to be included by eval.c instead of being
4579 compiled separately. Everything is declared static.
4581 * src/numb.h: Removed declarations of functions, as numb.c is now
4584 * src/builtin.c: Declaration of m4_mpeval() added.
4585 Inserted `mpeval' in builtin table.
4586 (do_eval): New function with common code for m4_eval and m4_mpeval.
4587 (m4_mpeval): New function for gmp version of eval.
4589 * src/m4.h: Declaration of mp_evaluate().
4591 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
4592 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
4594 * src/m4.c (main): m4 --version also shows which options were used
4595 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4597 1998-11-27 René Seindal <rene@seindal.dk>
4599 * Error messages now always print program name before input file
4600 name as specified by GNU coding standards. Reported by Akim
4601 Demaille <demaille@inf.enst.fr>.
4603 * doc/m4.texinfo (Include): Change due to changed error message
4607 * tests/get-them: Minor change to sed script due to changed error
4610 * src/m4.c (print_program_name): New func used to print program
4611 name, input file and line number in error (). Used as an
4612 error_print_progname handler.
4613 (reference_error): Removed.
4614 (main): Assigns error_print_progname.
4616 * src/m4.h (M4ERROR): Removed reference_error ().
4618 1998-11-25 René Seindal <rene@seindal.dk>
4620 * Updated to libtool 1.2b.
4622 * src/builtin.c (install_builtin_table): Added braces to avoid
4623 warning of ambiguous 'else'.
4625 * src/module.c: Inserted search path code from path.c modified to
4627 (module_init): Configured default path used only if M4MODPATH is
4629 (module_try_load): Now reads libMODULE.la as generated by libtool
4630 for actual module name.
4631 (module_load): Gives better error messages on failure.
4633 * src/m4.h: Added declarations of structures and functions for
4634 generic search path handling.
4636 * src/path.c: Removed all module specific code and introduced new
4637 functions of more generic search path handling.
4639 1998-11-24 René Seindal <rene@seindal.dk>
4641 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4642 included gettext, as <libintl.h> might not be found
4643 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4645 1998-11-22 René Seindal <rene@seindal.dk>
4647 * src/output.c (insert_diversion): Fixed bug that might cause m4
4648 to read from standard output! Triggered by input
4649 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4650 so now 'undivert(0)' does nothing.
4652 1998-11-18 René Seindal <rene@seindal.dk>
4656 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4657 could be changed when compiling a illegal regexp, causing later
4658 use of the regexp to dump core.
4660 * src/module.c (module_load): Changed error message to conform to
4663 * src/m4.c (usage): Added message about reporting bugs.
4665 * doc/m4.texinfo (Changeword): Corrected a wrong example.
4666 (Changeword): Added note about the type of regexps used.
4668 * ltconfig, ltmain.sh: New files from Libtool 1.2.
4670 * configure.in: Added calls to AM_ENABLE_SHARED, AM_DISABLE_STATIC
4671 and AM_PROG_LIBTOOL.
4673 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
4676 * modules/Makefile.am: Changed completely to compile modules using
4677 libtool. The modules are compiled as shared libraries, and are
4678 renamed when installed.
4680 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4681 USE_SHL_LOAD to HAVE_SHL_LOAD
4683 * src/builtin.c (shipout_string): Now tests for a NULL string.
4685 * src/module.c: New level of indirection around non-portable
4686 functions to load shared objects. Intended to encapsulate the non
4687 portable parts better and to reduce the number of #ifdefs in the
4690 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
4691 directory modules/ to the distribution.
4693 1998-11-15 René Seindal <rene@seindal.dk>
4697 * modules/stdlib.c: New module `stdlib' defining some standard
4698 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
4699 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4701 * src/builtin.c (shipout_string): New convenience function for
4702 builtins and modules.
4704 * src/module.c (module_load): Tentative support for
4705 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
4707 * Makefile.am (SUBDIRS): Directory modules added if configured.
4709 * modules/Makefile.am: Now correctly compiles and installs
4710 modules in pkglibexecdir.
4712 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
4713 These two are now initialised by autoconf macros.
4715 * src/path.c (module_env_init): MODULE_PATH is always on the
4718 * src/Makefile.am: Now generated pathconf.h which defined the
4719 default MODULE_PATH.

4722 where modules are installed.
4724 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4725 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4726 build and install automatically, and it is prepared for other
4727 interfacec than dlopen().
4729 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4730 current version of GNU m4. It is a GNU extension.

4810 1998-10-07 René Seindal <rene@seindal.dk>
4814 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4815 .test, as the files are no longer just m4 input.
4817 * tests/get-them (FILE): Changed .m4 extension to .test.
4819 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
4820 Otherwise quoted strings with leading whitespace first in a macro

4824 (expand_argument): Do.
4826 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

4832 builtin_table on the stack without installing its contents.
4833 (find_builtin_by_name): Added call to push_builtin_table() if
4834 reading frozen files. Otherwise the builtins named in the frozen
4835 files could not be found.

4838 1998-10-04 René Seindal <rene@seindal.dk>
4842 * configure.in (ALL_LINGUAS): Added Polish pl.po
4844 1998-10-03 René Seindal <rene@seindal.dk>

4854 * src/builtin.h: New file, declares some functions from builtin.c
4855 that are of use for other modules (shipout_int, numeric_arg,
4856 skip_space, bad_argc), and the macros ARG() and DECLARE().
4858 * src/builtin.c (install_builtin_table): New function. Each
4859 module brings in a builtin_table, which is pushed on a stack.
4860 (struct builtin_table): New struct for list of builtin_tables.
4861 (m4_loadmodule): New function to implement builtin "loadmodule".
4862 (shipout_int): No longer static, to be used by modules.

4880 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
4883 * configure.in: Added modules/Makefile to AC_OUTPUT.
4885 * configure.in: Added code to implement --with-modules. Tests for
4888 * acconfig.h: Added WITH_MODULES
4890 1998-10-02 René Seindal <rene@seindal.dk>
4892 * examples/Makefile.am (pkgdata_DATA): Removed special target for
4893 check and variables TESTS. These tests are now run from the
4896 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
4897 directory. The files stay there but the tests are run from the
4900 * tests/Makefile.am (EXTRA_DIST): Added run-test.
4902 * tests/run-test: New file. Run a test manually
4904 * tests/Makefile.am, tests/get_them: Moved automatically generated
4905 tests (from the manual) to sub directory tests/gentest/. The
4906 tests/ directory had gotten a bit messy.
4908 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4910 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
4911 wrap}.test: Added a few testcases.
4913 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4917 * lib/Makefile.am (noinst_HEADERS): regex.h added
4919 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
4920 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
4922 * acm4/Makefile.am: created providing rules to create
4923 $(top_srcdir)/acinclude.m4 to be used by aclocal.
4925 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
4926 `C'. Reported by Ulrich Drepper.
4928 * Makefile.am (SUBDIRS): Removed checks directory
4929 * configure.in (AC_OUTPUT): Removed checks/Makefile
4931 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
4932 the space when m4.texinfo is edited and whitespace.el is active.
4933 (Defn,example): idem.
4935 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4937 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
4938 ../COPYING. ../Makefile is a file which is certainly present when
4939 test is executed in testSubDir. One can't be sure that the COPYING
4940 file is in .. or ../.. in all situations, the ../Makefile is
4943 * doc/m4.texinfo (Include): adjusted expected test output
4944 according to new tests, i.e. the input will always come from the
4945 file `in' created by the test.
4947 * tests/Makefile.am: Added three lines at the top to get
4948 esyscmd.1.test working.
4950 * tests/get-them: modified to generate clearer tests who will need
4951 less maintenance when new test examples are created in
4952 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
4953 need the generic file `defs') shell scripts creating `in', `ok',
4954 `out' and when apropriate `okerr' and `err' in the directory
4955 `testSubDir' when executed. The compare of `ok' and `out'
4956 (and of `okerr' and `err') will be the exit status of the test.
4957 `out' must match `ok' (and `okerr' must match `err') for the test
4960 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
4961 the tests generated by tests/get-them getting it input normally
4962 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
4963 (dot) before the numeric part) is reserved for all other (hand
4964 written) tests. The `+' means one or more times.
4966 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4968 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
4969 supported short man page to refer to info documentation

4996 "changesyntax" to modify the syntax table.
4998 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
4999 table. All categories are assigned a syntax code and tokens are
5000 read according to this table.
5002 1998-08-09 René Seindal <rene@seindal.dk>
5004 * src/numb.{c,h}: New files, implements multiple precision eval
5005 using GNU gmp. Originally submitted by John Gerard Makecki
5006 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
5008 * doc/m4.texinfo (Eval): Added documentation for multiple
5009 precision arithmetic library support.
5011 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
5012 to accommodate multiple precision eval.

5021 patch from Mike Howard <mike@clove.com>
5023 1998-08-06 René Seindal <rene@seindal.dk>
5025 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
5028 1998-08-03 René Seindal <rene@seindal.dk>
5032 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
5033 and _ macro. M4 now builds with --disable-nls.
5035 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
5036 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
5038 * configure.in (ALL_LINGUAS): Added complete list of translations:

5084 src/stackovf.c: Rename _ to __P.
5085 * src/m4.h: Declare _ as a macro returning its argument, or else,
5086 include <libintl.h> and declare _ as gettext.

5143 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
5144 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

5164 Remove the sed filter after ansi2knr for debug.c. Use $O instead
5165 of $U, put underline in extensions rather than in basenames. Use
5166 implicit rules, now that regularity makes this possible.
5167 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
5168 of ansi2knr whenever it is needed.
5169 * configure.in: Adjusted for correct STACKOVF substitution.
5170 * src/debug.c (trace_format): When not __STDC__, use (...) as a

5187 Reported by Jim Kingdon.
5189 * {,/*}Makefile.in: Use && after all cd, in case they fail.
5191 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

5211 Reported by David MacKenzie.
5213 1994-10-01 François Pinard <pinard@iro.umontreal.ca>

5217 Reported by Jim Meyering.
5219 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
5221 * src/stackovf.c: Declare the handler_t typedef earlier in the
5222 code, use it for stackovf_handler.
5223 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
5224 casting sigsegv_handler.
5225 Reported by Robert Bernstein.
5227 * src/m4.c (main): Initialize program_name to argv[0] without
5229 Reported by Karl Berry.
5231 1994-09-18 François Pinard <pinard@iro.umontreal.ca>

5234 Reported by Karl Berry.
5236 1994-09-14 François Pinard <pinard@iro.umontreal.ca>
5238 * lib/Makefile.in (mostlyclean): Added.
5239 (TAGS): Make in $(srcdir).
5241 * configure.in: Use `choke me' in test, like everywhere!

5251 * Makefile.in: Make TAGS in lib also, not just in src.
5252 Reported by Karl Berry.
5254 * Makefile.in (distclean, realclean): Instead of recursively
5255 calling $(MAKE) for the -local part, allow parallel execution of
5256 -recursive and -local, only delay the removal of config.status,
5257 which is repeated in both goals.
5259 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
5263 * Makefile.in: Group all *clean-recursive goals in one, using sed
5264 to remove `-recursive' while calling make recursively. Also, use
5265 a subshell for each recursive $(MAKE).

5269 Reported by Kaveh R. Ghazi.
5271 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
5272 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
5275 * configure.in: Use date instead of touch for stamp-h.
5276 * Makefile.in (stamp-h.in): Idem.
5278 * Makefile.in (distclean, realclean): Force serial execution of
5279 both goals, in case parallel makes are being used.
5280 Reported by Jim Meyering.

5331 calling a function by that name. Declare the variable.
5332 * src/m4.h: Adjust declaration for prefix_all_buitins.
5333 * src/builtin.c (builtin_init): Merge in functionality from
5334 previous prefix_all_buitins function, while making entries in the
5335 symbol table, but not modifying the builtin description itself.
5337 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5338 because *many* compilers do not accept an empty `default:'.

5352 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
5353 a per buffer MAXIMUM_BUFFER_SIZE.
5355 * src/output.c (output_text): New function, for optimizing the
5356 output of strings of characters. Use it.
5358 1994-08-30 François Pinard <pinard@iro.umontreal.ca>

5363 * Makefile.in: Adjusted.
5364 * configure.in: Configure new Makefiles.
5366 * m4.h: Declare STRING typedef. Use it for comment and quote
5367 strings, adjusting all references. (This is the rudiments of a
5368 beginning for the eventual withdrawal of NUL terminated strings.)
5369 * output.c (shipout_text): Accept a length parameter, and use it.
5370 All callers adjusted.
5372 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
5374 * m4.h: Include <unistd.h> if it exists.

5390 * m4.c: Still accept -N, but do nothing with it.
5391 Reported by David MacKenzie.
5394 * output.c (freeze_diversions): New function.
5395 * m4.h: Declare freeze_diversions.
5396 * freeze.c: Document frozen file format, revise it, call
5397 freeze_diversions to add diversions to frozen format, and code to
5398 reload them properly.
5399 * m4.c: Do not undivert automatically at end when status being
5400 frozen. Do not call builtin_init when reloading frozen state.
5402 Speed up diversion processing:
5403 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5404 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5405 structure and variables, cached variables out of output_diversion,
5406 reallocate_diversion_for and OUTPUT_CHARACTER.
5407 (shipout_text, make_diversion, insert_diversion): Adapted to new

5415 dist works from another build directory.
5417 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5419 * symtab.c (hack_all_symbols): Use hash_table_size instead of
5420 constant HASHMAX, for -H option to work better.
5422 * builtin.c (DECLARE): Simplify by using _ ().
5424 * freeze.c: New file.
5425 * Makefile.in: Compile it, distribute it.
5426 * m4.c: Recognize, document and process --freeze-state (-F) and
5427 --reload-state (-R) options. Pass a true flag to builtin_init
5428 only if no reloading some state.
5429 * builtin.c (define_builtin): Remove static specifier.
5430 (find_builtin_by_name): Remove static specifier.

5446 Reported by Akiko Matsushita.
5448 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5450 * m4.h: Include <sys/types.h>.
5451 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5452 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5454 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm

5458 * debug.c: Prototype the forward declaration of debug_set_file.
5460 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5461 shadowing of this variable.
5462 * output.c (insert_diversion): Idem.
5464 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5465 (input_init): Duplicate default quote and comment strings.

5474 * m4.c (usage): Reorganize the --help output by topic. Include a
5475 description for debugging flags.
5477 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5479 * configure.in: If sigaction is available and SA_ONSTACK defined,
5480 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5481 defined, use sigvec. Else don't compile stackovf.c.
5482 * stackovf.c (setup_stackovf_trap): Idem.
5483 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5486 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
5488 * m4.c (usage): Replace printf par fputs.
5490 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5494 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5496 * configure.in: Check for sigaction and sigvec. Add a new delayed
5497 check for RLIMIT_STACK, combine in the checking for getrlimit.
5498 All those things are not universally available.
5499 * stackovf.c: Split setting up the trap handler and catching
5500 signals, for better taking care of various configure outcomes.
5501 * examples/stackovf.sh: Correct a typo.
5502 Reported by Eric Backus, Jim Avera and Jim Meyering.
5504 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5506 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5508 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5510 * Makefile.in: Modify so parallel make will not try making
5511 lib/libm4.a twice simultaneously.
5512 Reported by Jim Meyering.
5514 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5516 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5517 error message, for when no code possibility exists. Even if this
5518 line is completely #ifdef'ed out, it brings a syntax error.
5519 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5521 * Makefile.in (install): Have install depend on all too, for lib
5522 to be remade as needed.
5524 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5525 providing ulimit, instead of using only ksh.
5526 Reported by Jim Avera and Joseph E. Sacco.
5528 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5530 * Makefile.in (check): Have it depend on all instead of m4. In
5531 this way, a change in lib will be detected and processed.
5533 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5534 instead of using sscanf which stops as soon as there is a
5535 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5536 and divert(1xyzzy) were all accepted without any warning or error
5538 * m4.h: Declare strtol as long if not including stdlib.h.
5539 * configure.in: Check for limits.h, and replace strtol if missing.
5540 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5541 * lib/strtol.c: New file, from elsewhere.
5542 Reported by Andreas Schwab.
5544 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5546 * macro.c (expand_macro): Cast value to (boolean) prior to
5547 assigning it to traced.
5548 Reported by Tom McConnell.
5550 * Makefile.in (m4): Always make all in lib first.
5551 Reported by Jim Meyering.
5553 1994-07-06 Jim Avera <jima@netcom.com>
5555 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5556 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5557 handlers), and a default error message if the fault address is not
5558 available (when neither siginfo.h nor BSD sigcontext are supported).
5559 * configure.in: Changes for stackovf.h: Check for sigcontext,
5560 sigaction, sigstack, and define rlim_t as int if necessary.
5561 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5562 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5563 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5565 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5567 * configure.in: Use AC_SET_MAKE.
5568 * Makefile.in: Use @SET_MAKE@.
5569 Reported by Jim Meyering.
5571 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
5572 Reported by Ian Taylor.
5574 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5576 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5577 because siginfo.h is unrelated to standard headers, and siginfo.h
5578 is already checked for.
5579 Reported by Joseph E. Sacco.
5581 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5583 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5586 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5588 * builtin.c (substitute): Use \& to represent this part of the
5589 string which was matched by the whole regexp, instead of
5590 representing the whole string. Any usage of \0 issues a warning
5591 and acts like \&, it will disappear in some subsequent release.
5593 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5595 * m4.c: Complete prototype for forwarded declaration of usage.
5597 * input.c (init_macro_token): Correct own reference in error
5598 message. Previous name get_macro_func was referred to instead.
5599 (next_char): Correct own reference in error message. Previous
5600 name advance_input was referred to instead.
5602 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5603 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5604 and_term, not_term, logical_not_term, cmp_term, shift_term,
5605 add_term, mult_term, exp_term, unary_term, simple_term): Add
5606 prototype to forwarded declarations. Declare parameter v1 as
5607 eval_t * instead of int *. Same for local variable v2 in dyadic
5608 functions. Same for result in exp_term.
5609 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5610 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5611 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5612 (shipout_int): Cast first argument of ntoa to eval_t.
5613 Reported by Thorsten Ohl.
5615 * macro.c: Complete the prototypes of forwarded expand_macro and
5617 Reported by Thorsten Ohl.
5619 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5620 The Ultrix 3.1 compiler cannot do much with void pointers.
5622 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5623 * m4.c (xfree): Replace void * by voidstar.
5624 Reported by Tom McConnell.
5626 * ansi2knr.1: New, from elsewhere.
5627 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5629 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5630 stamp-h does not exist yet. This avoids running it a second time
5631 just after the initial ./configure.
5632 Reported by David MacKenzie and Tom McConnell.
5634 * m4.h: Replace the enum debug_info declaration with a series of
5635 #define's. The Ultrix 3.1 compiler would otherwise need casting
5636 (int) to most references, when used in expressions.
5637 Reported by Tom McConnell.
5639 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5641 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5642 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5643 calls the compiler. Previously, FP_PROTOTYPES was only calling
5644 the preprocessor; by not being subject to CFLAGS, this was
5645 discouraging those flags asking for ANSI compilation.
5646 * acconfig.h: Document HAVE_PROTOTYPES.
5647 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5648 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5649 Reported by Eric Backus.
5651 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5652 from the environment. Default CFLAGS to -g if not set.
5653 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5654 * lib/Makefile.in: Have CFLAGS substituted from configure.
5655 Reported by Eric Backus and Tom McConnell.
5657 * configure.in: m4_undefine changeword before using AC_ENABLE.
5659 * m4.h: Declare prototypes for error (for ANSI compilers only),
5660 prefix_all_builtins and reference_error.
5661 Reported by Tom McConnell.
5663 * input.c (set_word_regexp): Do not try to initialize the array
5664 test from a string, this does not work with non-ANSI compilers.
5665 Reported by Eric Backus.
5667 * Makefile.in (dist): Clean examples/ before saving it.
5668 (distclean-local): Also remove stamp-h.
5669 Reported by Eric Backus.
5671 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
5673 Reported by Tom McConnell.
5675 * checks/Makefile.in (clean): Depends on mostlyclean.
5676 (mostlyclean): New goal.
5678 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
5680 * Makefile.in (DISTFILES): Distribute install.sh.
5681 * install.sh: New file, copied from elsewhere.
5682 Reported by Assar Westerlund and Kaveh R. Ghazi.
5684 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
5686 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
5687 * acconfig.h: Explain ENABLE_CHANGEWORD.
5689 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
5690 from code provided by Pete Chown]
5691 * m4.h: Add original_text field to u_t variant of union u.
5692 Declare TOKEN_DATA_FUNC macro.
5693 * builtin.c: Declare changeword.
5694 (m4_changeword): New function.
5695 * input.c: Include "regex.h", define variables with word regexps.
5696 (input_init): Initialize the word regexp.
5697 (set_word_regexp): New.
5698 (next_token): Declare local variables, use the previous code if
5699 default_word_regexp is true. Else, match using a new code. Save
5701 * macro.c (expand_token): Ship out original text if not a macro
5703 Reported by Krste Asanovic and Pete Chown.
5705 [These modifs all depend upon ENABLE_CHANGEWORD]
5706 * m4.h: Declare external user_word_regexp.
5707 * m4.c: Declare user_word_regexp, and initialize it from
5708 --word-regexp or -W, or NULL if not specified.
5709 * input.c: Use user_word_regexp if specified, instead of
5710 DEFAULT_WORD_REGEXP.
5712 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
5715 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
5716 * checks/Makefile.in: Empty the suffix list.
5717 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
5719 * m4.c: Declare nesting_limit and initialize it to 250.
5720 Implement -LNUMBER or --nesting-limit=NUMBER to change its
5722 * m4.h: Declare nesting_limit as external.
5723 * macro.c (expand_macro): Stop execution whenever nesting limit
5725 Reported by Bengt Mertensson.
5727 * eval.c (evaluate): Diagnose excess characters in eval input.
5728 Things like `eval(08)' used to return 0 with no diagnostic.
5730 * m4.h: Capitalize first letter of all macro arguments in
5733 * m4.c: Declare warning_status, initialize it to 0. Add new
5734 option -E, or --fatal-warnings, which sets warning_status to
5735 EXIT_FAILURE instead.
5736 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
5737 EXIT_FAILURE if not otherwise done by header files.
5738 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
5739 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
5740 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
5741 argument of all M4ERROR calls.
5742 Reported by Noah Friedman.
5744 * examples/incl-test.m4: Renamed from incl_test.m4.
5745 * examples/include.m4: Include incl-test.m4 instead of
5747 * examples/multiquotes.m4: Renamed from multi-quotes.m.
5749 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
5751 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
5752 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
5753 also tested it on a Sun Sparc workstation running SunOS 4.x.
5755 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5756 49.format check, abusing a `union values' argument with sprintf
5757 without selecting the proper field. Now, save the formatting type
5758 first, delaying the fetch of the corresponding argument.
5759 Reported by Joseph E. Sacco and Tom Quinn.
5761 * format.c (format): Remove const from char *fmt declaration when
5762 not HAVE_EFGCVT, because a NUL may be forced into it.
5764 * m4.h: Declare atof() when not STDC_HEADERS.
5765 Reported by Joseph E. Sacco.
5767 * Regenerate configure using Autoconf 1.11, this corrects a
5768 problem about an incorrect cpp seting on NeXT 3.1.
5769 Reported by Alexander Lehmann.
5771 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
5773 * m4.h (_): Change argument from `x' to `Args'.
5775 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
5777 * m4.h: Rename Args() to _().

5784 standard headers, getrlimit and sigaction, define USE_STACKOVF and
5785 substitute ${U}stackovf.o for STACKOVF.
5786 * acconfig.h: Declare USE_STACKOVF.
5787 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
5788 * m4.h: Declare setup_stackovf_trap().

5794 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
5796 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
5798 1994-01-30 <pinard@iro.umontreal.ca>
5800 * m4.h: Remove definition of volatile, not used anymore.
5801 Reported by Jim Meyering and Joseph E. Sacco.
5803 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
5804 of `if ... else /* nothing */' for if macros.
5805 Reported by Jim Meyering.
5807 * builtin.c (m4_regexp): Reorganize the code for avoiding a
5808 warning from gcc about `repl' possibly used before defined.
5809 Reported by Jim Meyering.
5811 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5812 Reported by Jim Meyering.
5814 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5816 * m4.h: Move the conditional definition of volatile after the
5817 inclusion of system files, because they may define it first.
5819 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5821 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5822 get around a problem with Alpha make seeing a syntax error, there.
5823 Reported by Vern Paxson.
5825 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
5827 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.

5838 * m4.c: Initialize show_help and show_version to zero.
5840 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
5841 Use them in exit() and usage() calls.
5843 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
5845 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5846 syserr() macro. Delete errref, add reference_error and M4ERROR.
5847 * m4.c: Replace errref, which was returning an input reference
5848 string, with reference_error, which prints it on standard error.
5849 * builtin.c, output.c: Use errno as second parameter to error,
5850 instead of using syserr() with %s.
5851 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5852 Doing so, the program name appears after the input reference
5853 instead of before, which eases M-x next-error processing.
5855 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5857 * checks/get-them: Escape braces with backslashes in patterns,
5858 because HPUX-9.01 awk needs this.

5869 * *.c: Use error() systematically in place of all error macros,
5870 now that error() flushes stdout first. Make needed adjustments.
5872 * m4.h: Remove const in sys_errlist[] declaration, it creates
5873 conflicts on SGI and Alpha.
5874 Reported by Kaveh R. Ghazi.
5876 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

5894 * input.c (input_init): Initialize quote and comment strings
5895 explicitely instead of calling set_quotes and set_comment: by
5896 doing so, we ensure we do not free uninitialized variables.

5899 expected is on the left and the obtained on the right.
5901 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
5902 macros. Delete declarations for m4error, warning, fatal and
5903 internal_error, add declaration for error_message_prefix.
5904 * m4.c: Delete m4error, warning, fatal and internal_error
5905 routines, add error_message_prefix routine.
5906 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
5907 warning with WARNING*, fatal with FATAL* and internal_error with
5909 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
5910 this is not needed anymore.
5912 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
5913 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
5914 and debug_message, add declaration for debug_message_prefix.

5916 Delete debug_print and debug_message routines, add
5917 debug_message_prefix routine.
5918 * builtin.c, debug.c: Replace debug_print routine calls with
5919 DEBUG_PRINT* macro calls.

5925 (trace_format): Use stdarg instead of varargs if __STDC__.
5927 * configure.in: Remove checks for vfprintf and _doprnt. These
5928 implementations use varargs tricks which are not portable enough.
5929 * lib/vfprintf.c: Deleted.
5930 * lib/_doprnt.c: Deleted.
5931 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.

5951 Reported by Joel Sherrill.
5953 * builtin.c (prefix_all_builtins): Instead of the table size, use
5954 the null entry at end for stopping the loop. It was overwritten.
5955 Reported by Andreas Schwab and Jim Meyering.
5957 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
5958 Reported by Kaveh R. Ghazi.

6037 Reported by Jim Avera.
6039 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,
6040 etc., arguments, then ignore the superfluous one. m4 used to
6041 diagnose missing arguments and return the empty string.

6213 * lib/alloca.c: New, from elsewhere.
6214 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
6216 * m4.h: Do not define index/rindex if already defined. If
6217 FALSE/TRUE are already defined, do not redefine them, but merely
6218 define boolean typedef to int.
6220 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
6221 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
6222 because some C compilers do not like connectives with #ifdef.
6223 * m4.h: Define `volatile' only if __GNUC__, instead of once for
6224 __GNUC__ and once for __STDC__.
6225 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
6227 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
6228 Makefile dependencies. Without it, make keeps destroying and
6229 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
6231 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
6232 to diversion/DIVERSION, this was a spelling error.

6235 * version.h: Deleted.
6236 * Makefile.in: Remove references to version.h.
6238 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
6239 production, by using a simpler and more robust algorithm. This
6240 solves the problem of synclines sometimes written in the middle of
6241 an output line. Delete sync_line() and output_lines variable.
6242 * m4.h: Remove sync_line prototype and output_lines declaration.
6243 * input.c (next_char), output.c (shipout_text): Remove references
6245 * input.c (push_file, pop_file): Merely put the value -1 in
6246 output_current_line instead of calling sync_line, for delaying a
6247 single `#line NUM FILE' before next output line. Do not test
6248 for sync_output, because this is unnecessary clutter.
6249 * output.c (make_divertion, insert_divertion): Idem.
6250 * input.c: Rename must_advance_line to start_of_input_line, for
6253 * debug.c (trace_header): Select a new debug line format, which
6254 better complies with GNU standards for formatting error messages.
6255 With option `-dfl', M-x next-error might be used on the output.
6256 * m4.c (vmesg): Adjust format of error output to GNU standards.
6257 * m4.texinfo: Adjust examples for `make check' to work.
6259 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
6260 case for enum debug_info constants, which were all lower case.
6262 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
6264 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
6265 collected patches. I tried a few times using newer regex.[ch], it
6266 mysteriously stopped aborting with this one. Insecure feeling...
6267 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
6269 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
6271 * m4.c: Change `--no-warnings' to `--silent'.
6272 Reported by David MacKenzie.
6274 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
6275 leave it off for now. See comment in m4.c for justification.
6276 Reported by David MacKenzie.
6278 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
6279 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
6281 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
6283 * Makefile.in: Ensure recursive cleaning is done before local
6284 cleaning for all clean goals.
6286 * builtin.c (ntoa): Ensure the value is always interpreted as a
6287 signed quantity, whatever the radix is.
6289 1992-11-18 Jim Meyering <meyering@idefix>
6291 * builtin.c, format.c, input.c: Split long lines.
6292 * m4.c: Use typedef macro_definition instead of struct
6294 * symtab.c: Use typedef symbol instead of struct symbol.
6296 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
6298 * *.[ch]: Remove all trailing whitespace, in code and comments.
6300 * configure.in: Find some awk.
6301 * Makefile.in: Add $(AWK) to MDEFINES.
6302 * checks/Makefile.in: Transmit $(AWK) to get_them.
6303 * checks/get_them: Use $AWK instead of gawk. Add a close in the
6304 awk script when switching files, because without this, mawk runs
6305 out of file descriptors.
6307 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
6309 * Makefile.in (realclean): Delete m4.info*.

6317 recognizable by next-error, also use a better message.
6319 1992-11-16 Jim Meyering <meyering@idefix>
6321 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
6322 And use that only if __GNUC__ since we're using it's GCC-specific
6323 semantics that tell the compiler the associated function doesn't
6326 * builtin.c (substitute): Don't use character as an array index.
6327 (dumpdef_cmp): Make formal arguments `const void *' to avoid
6328 warnings with gcc -W -Wall on systems with qsort prototype.
6329 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
6332 * eval.c (most functions): Add parentheses to assignments used
6333 as truth values go avoid warnings from gcc -Wall.
6335 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
6336 any functions that don't need external scope.
6338 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6339 (many functions and arrays): Declare `const'.
6341 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6343 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6344 removing the declaration from m4.h. Also rename false to FALSE
6347 * lib/Makefile.in (Makefile): New goal.
6349 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6350 so heavily loaded. It gets more easily overridable, calling make.
6351 Reported by Jim Meyering.
6353 * Makefile.in (dist): Get .fname from the current directory name,
6354 instead of from version.h. I need updating many files manually,
6355 when the version changes, version.h is just one of them.
6357 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6359 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6360 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6361 Reported by Tom McConnell.
6363 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6365 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6366 39.cleardiv, which were describing missing or spurious newlines.
6367 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6368 do not depend on machine word size, `/bin/false' implementation,
6369 or `wc' output format. `make check' is more dependable, now.
6371 * checks/check_them: Summarize the failed tests by listing their
6372 name, at end. If none, issue `All checks successful'. Output
6373 `Checking' instead of `Input file:'.
6375 * checks/get_them, checks/check_them: Reindented.
6377 * Makefile.in (dist): chmod a+r before making the tar file.
6379 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6381 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6383 * input.c (next_token): Reinitialize token_buttom just after using
6384 it as a watermark with obstack_free. Or else, a future token, big
6385 enough for triggering reallocation of the obstack chunk, could
6386 void the initialized value of token_buttom, later causing panic in
6387 obstack_free. Rename token_buttom to token_bottom everywhere.
6389 * m4.h: Before declaring errno, first include <errno.h> and
6390 ensure that it does not define errno.
6391 Reported by Richard Stallman.
6393 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6395 * builtin.c: Define and use DECLARE macro for builtins.
6397 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6398 argument, this is a common idiom for introducing long comments.
6400 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6401 arguments. The last argument was silently ignored.
6403 * m4.c (cmd_error): Add a missing semicolon before va_end().
6405 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6407 * Makefile.in: Now handle protoized sources. Define and use U.
6408 Compile and use ansi2knr with old compilers. Update DISTFILES.
6409 Add `aclocal.m4' to `configure' dependencies.
6410 * ansi2knr.c: New, from Ghostscript distribution.
6411 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6412 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6413 * aclocal.m4: New, provide FP_PROTOTYPES.
6414 * m4.h: Conditionnaly protoized through Args, save for varags.
6415 * builtin.c: Protoized. Then:
6416 Include <sys/types.h> if size_t is not defined, before "regex.h".
6417 (m4_ifelse): Fetch built-in name properly for diagnostic.
6418 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6419 (m4_regexp): Add const to `msg' declaration.
6420 (m4_patsubst): Add const to `msg' declaration.
6421 * debug.c: Protoized, save for varargs.
6422 * eval.c: Protoized.
6423 * format.c: Protoized.
6424 * input.c: Protoized.
6425 * m4.c: Protoized, save for varargs. Then:
6426 (xfree): Accept void * instead of char *.
6427 (xmalloc): Return void * instead of char *.
6428 (xrealloc): Accept and return void * instead of char *.
6429 * macro.c: Protoized.
6430 * output.c: Protoized.
6431 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6432 * symtab.c: Protoized.
6434 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6436 * m4.texinfo: Remove directory from diagnostics in 30.include,
6437 51.eval, 56.errprint and 57.m4exit tests.
6439 * m4.h: Remove declarations for int or void system functions, they
6440 cause more conflicting trouble than they make good.
6442 * configure.in: Avoid configuration header file. Add some tests.
6443 * m4.h: Remove #include "config.h".
6444 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6445 Then, rewritten for better compliance with GNU standards.
6447 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6449 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6450 because of a misplaced #endif.
6452 * Many *.[hc] files: Correct intra-line spacing here and there,
6453 according to GNU indent 1.6 advice.
6455 * configure.in: New, using Autoconf 1.2.
6456 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6457 * Delete old configure.in, configure, etc/configure.in,
6458 etc/configure, lib/configure.in, lib/configure and config/*.
6459 Reported by Jason Merrill.

6472 * checks/get_them: New location for etc/get_examples.
6473 * checks/check_them: New location for etc/check_examples.

6479 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6481 * Makefile.in (check): Add m4 as dependency.
6483 * m4.c: Accept --no-warnings instead of --no_warnings, and

6508 Reported by Michael Fetterman.
6510 * eval.c, input.c, m4.h: Remove last comma in enums.
6511 Reported by Mike Lijewski.
6513 * Transfer of maintenance duties from René to François.

6529 * The built-in format can now be configured to use sprintf as
6530 the formatting engine, for systems without [efg]cvt(3).
6532 * GNU library code is moved to the ./lib subdirectory; other
6533 utility files are now in ./etc.

6540 Francois Pinard and Roland H. Pesch for providing me with reports.
6542 * The builtins incr and decr are now implemented without use of
6545 * The builtin indir is added, to allow for indirect macro calls
6546 (allows use of "illegal" macro names).
6548 * The debugging and tracing facilities has been enhanced
6549 considerably. See the manual for details.
6551 * The -tMACRO option is added, marks MACRO for tracing as soon
6554 * Builtins are traced after renaming iff they were before.
