84 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
86 <DEFAULTS>: Delay computation of variables based on $at_dir...

107 Autoconf version in which the AC_PROG_INSTALL change was done.
108 Suggested by Paul Eggert.
110 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
112 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
113 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
114 mode, we change to the source directory, also set $ac_pwd so we
115 do not go back to the build tree for the next config subdir.
116 * tests/torture.at (Deep Package): Extend test to contain two
117 config subdirs on the top level.
119 Fix parallel `maintainer-check'.

185 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
187 * tests/torture.at (srcdir): Fix quoting.
189 Do not pass top_srcdir to configure scripts in testsuite.
190 * tests/autotest.at (srcdir propagation): Copy install-sh to

193 * tests/base.at (Input/Output): Likewise.
194 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
195 config.guess, and config.sub to test source tree.
196 Drop AC_CONFIG_AUX_DIR setting.

198 * tests/torture.at (Substitute a 2000-byte string): Drop
199 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
200 (Substitute a newline, datarootdir workaround): Likewise.
201 (Define a newline): Adjust for linenumber changes in configure.ac.
202 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
204 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
205 if `pwd` contains whitespace.
207 Quote $abs_top_srcdir in tests.

209 * tests/tools.at (Syntax of the shell scripts): Likewise.
211 * tests/m4sh.at (LINENO): Quote $0.
213 Fix testsuite program wrapper for whitespace in `pwd`.
214 The problem here is that the usual mantra is that command
215 variables can contain arguments, thus we cannot just escape
216 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
217 $top_builddir/tests directory early in $PATH, so that the
218 wrappers are found by their plain name.
219 * tests/wrapper.as: Put $testdir early in $PATH.
220 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
222 Proper config.status --file/--header and $srcdir escaping.

228 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
230 Fix Autotest for whitespace in `pwd`.
231 * lib/autotest/general.m4 (AT_INIT)
232 <at_func_create_debugging_script, Driver Loop>:
234 * tests/autotest.at (whitespace in absolute testdir): New test.
236 * lib/autom4te.in: Quote @datadir@.
238 Proper file name escaping in Autoconf programs and Perl modules.
239 This includes escaping of characters special to the shell
240 as well as special to Perl, e.g., leading `<' or `>'.
241 For example, when $file starts with `>', `open ">$file"'
242 wrongly tries to append to a different file.
243 * bin/autoconf.as: Fix quoting for autom4te options.
244 * lib/Autom4te/General.pm (shell_quote): New function, taken
245 from coreutils, written by Jim Meyering.
247 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
249 * bin/autoreconf.in (parse_args): Likewise.
250 * bin/autoscan.in (main): Likewise.
251 * bin/autoupdate.in (main): Likewise.
252 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
253 * bin/ifnames.in: Likewise, XFile usage fixes.
254 * tests/tools.at (autom4te and whitespace in file names): Extend
255 test. Test twice, with special characters allowed on w32, and the
256 rest. Test leading and trailing whitespace, for `open_quote'.
257 (autotools and whitespace in file names): New, analogous test.
258 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
259 by Russ Allbery and Eric Blake.
262 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
263 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
264 * lib/Autom4te/FileUtils.pm (open_quote): New function.
265 (update_file, contents): Use it.
267 * Makefile.am (autom4te-update): Rewrite for git.
269 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
271 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
274 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
275 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
277 2007-12-04 Eric Blake <ebb9@byu.net>
279 Manually resync with gnulib, since 'make cvs-update' no longer works.
280 * build-aux/config.guess: New upstream version.
281 * build-aux/config.sub: Likewise.
283 When using older automake, don't downgrade build-aux/texinfo.tex.
284 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
285 * doc/Makefile.am (TEXINFO_TEX): Add.
287 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
289 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
290 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
291 #undef as this runs afoul of our new way of creating config.h.
292 Problem reported by Jim Meyering in
293 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
295 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
297 Fix autom4te for unusual characters in input file names.
298 * bin/autom4te.in (files_to_options): Quote active characters
300 * tests/tools.at (autom4te and white space in file names):
303 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
304 Document that Tru64 awk always splits $0.
306 2007-11-24 Stepan Kasal <kasal@ucw.cz>
308 * lib/autotest/general.m4 (AT_INIT): Do not extract the
309 `#AT_STOP_...' line at the end of each test.
311 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
313 * lib/autotest/general.m4 (AT_INIT): For awk line number
314 extraction script, ensure `$at_group' has a defined value
315 even for the empty set, and properly quote its usage inside
318 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
320 * doc/autoconf.texi (Shell Functions): New chapter. Document
321 IRIX sh $0 issue in functions, move content from ...
322 (Portable Shell): ... here.
323 (Shell Script Compiler): Note that shell functions are not
324 totally unportable any more.
326 2007-11-22 Stepan Kasal <kasal@ucw.cz>
327 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
329 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
330 extracting the line numbers of the last needed test.
332 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
334 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
337 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
339 Fix IRIX testsuite debugging failures: $0 in functions.
340 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
341 Do not use $0 inside a function, as IRIX sh will set that to the
342 function name rather than the script invocation name.
344 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
345 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
347 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
348 to extract test scripts.
349 (AT_INIT): Extract and cache test script line numbers.
351 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
353 * lib/autotest/general.m4: Revert 2007-11-15 patch and
354 subsequent fixups; the awk -> here-document conversion trashes
355 performance too much with AIX sh.
357 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
359 * tests/local.at: Do not test m4, perl with AT_TESTED.
361 Diagnose and guard against write errors dealing with config.status.
362 The general idea is this: all write failures from `configure'
363 writing `config.status' are indicated by $ac_write_error, which
364 is only checked at the end. This is safe because config.status
365 code is not executed before the file is complete. Other write
366 failures, be they inside config.status, or in sub shell/awk
367 scripts spawned from configure or config.status, typically need
368 earlier checking, as their results are used right afterwards.
369 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
370 before writing config.status, check afterwards.
371 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
372 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
373 Set `ac_write_error' for write failures to config.status. Barf
374 upon write failures to temporary files.
375 Adjust note about closing and reopening the here-document.
376 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
377 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
378 reopening the here-document.
379 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
380 Ensure `ac_write_error' does not escape into config.status.
381 Also, add a couple of code paths not yet exercised in the test
382 suite: a config file with input from stdin, and a config header
384 Suggestion for catching write errors by Bruno Haible.
386 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
388 Avoid error with Tru64 awk and testsuite lines with many words.
389 * lib/autotest/general.m4 (AT_INIT): In the awk script that
390 reads the testsuite, set the field separator to an unusual value,
391 in order to not run over the limit of 199 fields. Tru64 4.0D awk
392 even splits the input if $i, i>0, was never accessed in the script.
394 Revert 2007-10-17 change.
395 * TODO: Multiline args in config files and headers mean something
396 different and are not fixed, see
397 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

456 2007-11-13 Jim Meyering <meyering@redhat.com>
458 Clean up the rule to create "expr".
459 * tests/Makefile.am (expr): Don't redirect directly to target.
460 Redirect just once, not for each echo statement.
461 Use $@, not literal "expr".
463 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
465 Don't worry about preprocessor when testing long long.
466 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html

468 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
469 These no longer check for preprocessor flaws.
470 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
471 Do not check for preprocessor flaws.
473 2007-11-13 Jim Meyering <meyering@redhat.com>
475 Adapt dependencies, now that a version change doesn't modify configure.ac
476 * GNUmakefile: Remove "make clean" kludge.

485 ":;{" shorthand as in previous patch.
487 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
489 * doc/autoconf.texi (Limitations of Builtins): Document problem
490 with { ... } a bit more clearly. Suggest ":;{" as a shorthand

502 Remove the autoreconf-provided INSTALL, so that we regenerate it.
503 * GNUmakefile (dummy): Remove INSTALL.
505 Remove racy commands to build scripts in bin/ and tests/.
506 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
507 are guaranteed to be built, remove the rules that tried to build
508 them. Before, with a parallel build, these rules could lead to
509 two processes writing tests/wrapper.in concurrently.
511 Build in man/ only *after* building in bin/ and tests/.
512 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
513 in both bin/ and tests/.
515 Accommodate non-srcdir build-from-checkout.
516 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
517 Use git's --git-dir=$srcdir/.git option.
518 Add quotes, in case tarball_version_file contains shell meta-characters.
519 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
520 * configure.ac: Pass "." to git-version-gen.
522 Avoid spurious test failures due to version skew.
523 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

552 Ignore configure --help* errors due to LINENO-impaired shells.
553 * tests/torture.at (Configuring subdirectories, Deep Package):
554 In the --help* tests in read-only trees, make `.' temporarily
555 writable again for the `stderr' file, and ignore errors due to
556 the attempt to write configure.lineno.
557 Report by Patrick Welche.
559 2007-11-10 Jim Meyering <meyering@redhat.com>
561 Generate package.m4 in build-dir, not srcdir.
562 * tests/Makefile.am (package.m4): Adjust target.
563 Don't redirect directly to $@.
564 (CLEANFILES): Add package.m4.
565 ($(TESTSUITE)): Depend on just-built package.m4, not the one
567 When running $(AUTOTEST), search "." before searching $(srcdir).
569 Avoid a race condition that would make parallel "distclean" fail.
570 * tests/Makefile.am (distclean-generic): Replace the default,
571 automake-provided rule with an identical one, but with an additional
572 dependency on distclean-local. Simply adding the dependency would
573 cause automake not to emit the rule at all.
574 * BUGS: Building with -jN works, now.
576 Distribute git-version-gen.
577 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
578 since GNUmakefile is distributed, and requires it for dist* rules.
580 Remove two more generated files from version control.
581 * INSTALL: Remove generated file.
582 * lib/autoscan/autoscan.list: Remove generated file.
584 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
586 * GNUmakefile (PATH): Remove stray apostrophes; they become
587 part of PATH, which isn't wanted here.

596 Report by Bob Friesenhahn.
598 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
599 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
600 function, to parametrize arithmetic with expr vs. the shell.
601 Use it where possible.
602 Suggestion by Benoit Sigoure.
604 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
606 Adjust the documentation of autotest WRT atlocal.
607 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
608 when using Automake, to write a rule to produce atlocal, since it's
609 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
610 distributed, not atconfig.in.
612 2007-11-04 Eric Blake <ebb9@byu.net>
614 Update list information.
615 * README: Mention new autoconf-commit list.

630 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
631 * build-aux/git-version-gen: This syncs from coreutils.
633 Adjust the build procedure so "make check" works reliably.
634 * README-hacking: Include an extra step between "make" and
635 "make check" to ensure that the latter passes.
637 Use just-built tools, when possible.
638 * GNUmakefile (PATH): Set and export here, ...
639 (dummy): ... rather than here.

669 2007-11-03 Jim Meyering <meyering@redhat.com>
671 Remove automake-provided files from version control.

674 * build-aux/missing: Remove file.
675 * build-aux/mdate-sh: Remove file.

691 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
692 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
693 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
694 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
695 Suggested by Paul Eggert.
697 2007-10-28 Jim Meyering <meyering@redhat.com>
699 * README-hacking: Autoconf, Automake, and Perl are required to build.
700 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
702 2007-10-28 Jim Meyering <meyering@redhat.com>
704 README-hacking: Recommend running autoreconf -vi.
705 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
706 so that we use just-built tools when they're available.
707 Suggestions from Ralf Wildenhues.
709 2007-10-28 Jim Meyering <meyering@redhat.com>
711 Make inter-release --version output more useful.
713 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
714 which indicates that it is built using the 19th change set
715 (in _some_ repository) following the "v2.61a" tag, and that 58dd
716 is a prefix of the commit SHA1.
717 * build-aux/git-version-gen: New file.
718 * configure.ac: Run it to set the version.
719 (AM_INIT_AUTOMAKE): Don't check NEWS here.

721 in distribution tarballs, never in a checked-out repository.
722 * .gitignore: Add .version here, too. Just in case.
723 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
724 not configure.ac, now that the version number changes automatically.
726 Ensure that $(VERSION) is up to date for dist-related targets.
727 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
728 git-version-gen doesn't match $(VERSION), but only for dist targets.
730 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

772 Don't check for bug in HP-UX 11.00 cpp.
773 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
774 Use -1ull rather than -1u, since that causes problems with gnulib; see
775 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

793 escaping of backslash in here-documents.
795 Fix `Deep Package' test failure on FreeBSD.

799 this resolution. Fixes test failure on FreeBSD.
801 Fix config header generation with AIX awk.

2025 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2026 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2027 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2028 works but the latter doesn't, then it's a valid type.
2029 This lets people use function types and so forth.
2030 For C++ there doesn't seem to be a simple solution, so leave it alone.
2031 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2032 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2033 AC_CHECK_TYPE; that wasn't documented or necessary.
2035 2007-04-11 Stepan Kasal <kasal@ucw.cz>

2121 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
2122 Reindent for sanity's sake.
2124 2007-02-24 Eric Blake <ebb9@byu.net>

2204 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2205 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2206 substitution will still be done by the special code.

2228 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2230 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2231 early on the reader side, drop stderr of the input to avoid
2232 `broken pipe' error output; this may happen even with shell
2233 builtin `echo' of some bash versions. Reports by Ian Macdonald
2234 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2236 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2238 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

2249 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2250 * doc/autoconf.texi (Signed Overflow Examples): Give more
2251 discussion about the allow_superuser_privileges example,
2252 and change it a bit to make things clearer.
2253 (Optimization and Wraparound): Clarify whether the compiler
2254 will generate an infinite loop for the example derived from
2255 Autoconf's mktime test.
2256 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2257 Also, clarify unsigned multiplication overflow.
2259 2007-01-04 Eric Blake <ebb9@byu.net>
2261 * bin/Makefile.am (RELEASE_YEAR): New macro.
2262 (edit): Use it to supply correct copyright year to scripts.
2263 * bin/autoconf.as (version): Use it.
2264 * bin/autoheader.in ($version): Likewise.
2265 * bin/autom4te.in ($version): Likewise.
2266 * bin/autoreconf.in ($version): Likewise.
2267 * bin/autoscan.in ($version): Likewise.

2269 * bin/ifnames.in ($version): Likewise.
2271 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2273 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2274 feedback. The most important changes document what happens when
2275 you convert an out-of-range value to a signed integer type, and
2276 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2279 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2280 rewrite, taking notions from the recent discussion on the gcc and
2281 autoconf mailing lists; please see
2282 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2283 and follow the many links.
2284 (Integer Overflow Basics, Signed Overflow Examples):
2285 (Optimization and Wraparound, Signed Overflow Advice):
2286 (Signed Integer Division): New sections.
2288 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2290 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2291 preprocessor macro arguments in traced name.
2292 * doc/autoconf.texi (Defining symbols): Document longstanding
2293 support for AC_DEFINE-ing macros with arguments, and document
2294 behavior when the same variable has multiple AC_DEFINEs.
2295 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2296 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2297 macros directly, giving much shorter and simpler code.
2299 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2301 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2302 space before "$ac_configure_args" to prevent a 'config.status
2303 --recheck' failure if ac_configure_args doesn't contain a leading
2304 space. This works around a problem with the XEmacs configure.ac,
2305 which uses the (undocumented) ac_configure_args variable
2306 inconsistently with Autoconf.
2308 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2310 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2311 Include <limits.h>, and use its INT_MAX to rewrite the
2312 j loop so that it does not overflow 'int'. Problem reported by
2314 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2315 Play it safe by shifting left by 1 rather than multiplying by 2,
2316 as GCC is less likely to optimize this away when the value
2317 is signed (when it assumes overflow leads to undefined behavior).
2318 Also, don't assume time_t uses two's complement.
2320 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2322 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2323 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2324 dumps core on it. Report by Tim Rice.
2326 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2328 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2329 --disable-option-checking to --help output even when
2330 AC_PRESERVE_HELP_ORDER is not used.
2331 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2332 --with argument, rather than argument with [-.] replaced by
2334 * NEWS: Fix typo in previous change; the news was in the
2337 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2339 * NEWS: Warnings are now generated by default for unknown
2340 --enable-* and --with-* options.
2341 * doc/autoconf.texi (Option Checking): Renamed from
2342 (Configure Option Checking). Tighten up the wording a bit.
2343 (External Software, Package Options): Cross-reference to Option
2344 Checking, and use this to shorten our section.
2345 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2346 "$x" to test "x$foo" != x.
2347 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2348 Don't warn if $enable_option_checking is "no".
2349 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2350 ac_unrecognized_opts to the empty string.
2351 Don't echo the unrecognized opts, as this might mishandle
2352 backslashes or leading -.
2353 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2354 usage next to the other --disable-FEATURE options in the
2357 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2359 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2360 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2361 Print warning for unrecognized --with and --enable options
2362 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2363 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2364 Disable option checking when subdirs are configured.
2365 (AC_OUTPUT): If warnings are enabled, print warning about
2366 unrecognized --with and --enable options at the end of
2367 the configure output (as well as at the beginning).
2368 * doc/autoconf.texi (Option Checking): New node.
2369 Document new option warning functionality.
2371 2006-12-16 Eric Blake <ebb9@byu.net>
2373 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2374 * NEWS: Start news for current version.
2376 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2378 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2379 Define HAVE_GETMNTENT to 1, not to the empty string.
2380 Problem originally reported by Jochen Friedrich in
2381 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2383 This change prompted by a problem report by Andrey Simonenko in
2384 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2385 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2386 object-like macros only, in the traditional portable character
2388 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2389 Warn about attempts to define things that are not identifiers.
2390 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2391 awful hack that AC_DEFINEd macro names containing parentheses.
2393 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2395 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2396 too drastic, even if Texinfo in theory requires it for info mode.
2398 (config.status Invocation): Renamed back from Recreating a
2400 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2401 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2403 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2405 * NEWS: Version 2.61a.
2407 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2408 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2410 * NEWS: Document changes with echo and printf, and the lack
2411 of limits on the total size of multi-line values of substituted
2412 variables, and the AC_FUNC_FSEEKO fix.
2414 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2416 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2417 Writing configure.ac.
2418 (Autoconf Input Layout): Renamed from configure.ac Layout.
2419 (Recreating a Configuration): Renamed from config.status Invocation.
2420 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2421 (acconfig Header): Renamed from acconfig.h.
2422 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2423 (Writing Testsuites): Renamed from Writing testsuite.at.
2424 (Autom4te Cache): Renamed from autom4te.cache.
2426 * BUGS: Remove mention of VPATH problem, since it's now documented
2427 not to be a bug in the Autoconf build procedure itself, but rather
2428 a problem with the proprietary `make' programs.
2430 * doc/autoconf.texi (Build Directories): Add a cross reference
2433 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2434 * doc/standards.texi: Sync from gnulib.
2436 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2437 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2438 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2439 generated automatically.
2441 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2443 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2444 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2445 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2447 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2449 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2450 `CEOF$ac_eof' special marker, the awk script cannot contain a
2451 line matching `^CEOF', so this is not needed any more.
2452 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2453 special marker in the test.
2455 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2457 * tests/tools.at (autom4te preselections): Use `find -newer';
2458 remove one of the sleeps.
2460 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2461 more readable, using ...
2462 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2464 * doc/autoconf.texi (autoheader Invocation): Do not double-
2465 quote the parameter of `AH_BOTTOM' in the example.
2467 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2469 * doc/autoconf.texi (Configuration Headers): Remove the
2470 example with multiple input files.
2471 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2472 multiple input files.
2474 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2476 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2477 creating the awk substitution script, handle one input line at a
2478 time, so that the maximum length of a substituted (multi-line)
2479 value is not limited by the size of the sed pattern space.
2480 The trade-off is a slightly repetitive sed script.
2481 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2482 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2483 * tests/torture.at (Substitute a 2000-byte string): Increase the
2484 test with several long lines, they should not be caught by sed
2487 * tests/tools.at (autom4te preselections): New test, to flag
2488 entries missing from autom4te.cfg.
2489 Report by David Byron <dbyron@hheld.com>.
2491 * tests/torture.at (Substitute a 2000-byte string): Actually use
2492 AC_PROG_AWK, so the last change works as intended.
2493 (Substitute and define special characters): Likewise.
2494 (Substitute a newline): Likewise.
2496 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2497 instead of `awk' consistently.
2498 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2499 * tests/torture.at (Torturing config.status): Test both the
2500 result of AC_PROG_AWK and plain awk.
2501 (Substitute a 2000-byte string): Likewise.
2502 (Substitute and define special characters): Likewise.
2503 (Substitute a newline): Likewise.
2505 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2507 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2508 can be assigned to a function pointer. Problem reported by
2509 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2510 part of a patch by Ralf Wildenhues in that same bug report.
2512 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2514 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2515 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2517 2006-12-01 Eric Blake <ebb9@byu.net>
2519 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2520 cross-compiling from cygwin to mingw.
2521 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2522 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2523 to lib/autoconf/c.m4.
2525 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2527 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2528 string for more reliable failure. Wrap the entire test that
2529 causes the broken Solaris printf to dump core, in a subshell,
2530 so the segmentation fault message is reliably suppressed.
2531 Fix shell expansion errors by using /usr/ucb/echo always;
2532 avoid an error on systems without it by another subshell.
2533 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2534 subshell-$as_echo to `as_echo', for better error message.
2536 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2538 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2539 `BASH_SOURCE' contain a newline, set them to empty, as they may
2542 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2544 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2545 years and is too hard to maintain now. The last straw was
2546 reported by Jerker Baeck in
2547 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2548 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2549 * doc/autoconf.texi (Particular Functions): Move
2550 AC_FUNC_SETVBUF_REVERSED from here...
2551 (Obsolete Macros): ... to here. Say that it does nothing now.
2552 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2553 Turn into (almost) a no-op.
2555 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2557 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2558 These macros are obsolescent and new applications shouldn't need them.
2559 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2560 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2561 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2562 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2563 (AC_FUNC_VPRINTF): Likewise.
2564 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2565 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2566 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2568 * doc/autoconf.texi (Setting Output Variables): Mention that
2569 @VAR1@VAR2 has unspecified behavior. Problem reported by
2571 * NEWS: Mention this.
2573 * Makefile.am: Put only a single '#' into the copyright notice,
2574 so that it's also present in the output file. Standardize wording
2575 in makefile copyright notices to match GNU coding standards.
2576 * bin/Makefile.am: Likewise.
2577 * doc/Makefile.am: Likewise.
2578 * lib/Makefile.am: Likewise.
2579 * lib/freeze.mk: Likewise.
2580 * lib/autoconf/Makefile.am: Likewise.
2581 * lib/autoscan/Makefile.am: Likewise.
2582 * lib/autotest/Makefile.am: Likewise.
2583 * lib/m4sugar/Makefile.am: Likewise.
2584 * man/Makefile.am: Likewise.
2585 * tests/Makefile.am: Likewise.
2586 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2589 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2592 in the sed script that mangles the awk script: delete up to the
2593 first exclamation mark only.
2594 * tests/torture.at (Substitute and define special characters):
2597 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2599 Rewrite config files generation: avoid quadratic growth in
2600 the number of substituted variables by using awk instead of sed
2601 for the bulk of the substitutions.
2602 * NEWS: Mention this.
2603 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2604 forbidden in the output (and thus input) file.
2605 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2606 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2607 generate just one large awk script for substitutions,
2608 eliminating much of the earlier complexity, while adding some
2609 new complexity. Only expand the substitution templates at
2610 configure time, for smaller configure script size. If
2611 _AC_SUBST_FILES are used, test 'awk' for working getline support
2612 at config.status time. If absent, interpolate through the
2613 shell. The awk script was written with much help
2614 from Paolo Bonzini and Paul Eggert.
2615 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2616 (_AC_SED_FRAG_NUM): Likewise.
2617 (_AC_SUBST_CMDS): Renamed from...
2618 (_AC_SED_CMDS): ...this.
2619 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2620 * tests/torture.at (Substitute a 2000-byte string): Also
2621 substitute a line with 1000 words, and a variable with several
2623 (Substitute and define special characters): Test awk special
2624 characters, and put substitution input strings `@foo@' in the
2625 output, to test that no recursion happens; test several other
2626 combinations from Paolo Bonzini.
2628 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2630 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2631 that replaced echo with AS_ECHO where this wasn't necessary.
2632 Problem reportd by Ralf Wildenhues.
2633 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2634 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2635 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2637 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2639 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2641 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2643 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2644 that traditional Awk lacks 3-arg "split". It has it.
2645 Mention that FS must be a single character, and a few other
2646 99-byte limits of traditional Awk.
2647 Mention that if (i in a) doesn't work with traditional Awk.
2649 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2651 * tests/autotest.at (BSx641-newline in command):
2652 (BS-BS-newline in command, BSx640-newline in command):
2653 (Newline-CODE-BS-newline in command):
2654 (Single-quote-BS-newline in command):
2655 (Single-quote-newline-BS-newline in command):
2656 Use printf '%s\n' instead of echo, for portability to hosts
2657 where echo interprets backslashes. This will break on hosts
2658 that lack printf, but for now let's assume all such hosts
2659 are dead (if not, we should get reports of test failures).
2661 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2663 'echo' has some portability problems, when given a first argument
2664 with a leading '-', or when given any argument containing '\'.
2665 Avoid using 'echo' in these cases.
2666 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2667 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
2668 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2669 * lib/autotest/general.m4 (AT_INIT): Likewise.
2670 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2671 argument might be unportable.
2672 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
2673 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
2674 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
2675 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
2676 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
2677 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
2678 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
2679 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
2680 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
2681 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
2682 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
2683 (AC_PROG_MAKE_SET): Likewise.
2684 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
2685 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
2686 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
2687 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
2688 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
2689 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
2690 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2691 * bin/autoconf.as: Redo verbose flag implementation, as the old
2692 scheme wouldn't work with AS_ECHO.
2693 * lib/autotest/general.m4 (AT_INIT): Likewise.
2694 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2695 Don't use ECHO_T, since ECHO_N is now reliable.
2696 * lib/autotest/general.m4 (AT_INIT): Likewise.
2697 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2698 rather than using a here-document to put the script into a file.
2699 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2701 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2702 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2703 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2704 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2705 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2706 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2707 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2708 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2709 operand, as AS_ECHO requires. Avoid double file name expansion.
2710 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2711 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2712 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2713 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2714 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2715 Double-quote strings that would otherwise contain M4 comments.
2716 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2718 * configure.ac (AC_INIT): Bump to 2.61a.
2721 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2725 * configure.ac (AC_INIT): Bump to 2.61.
2728 * tests/autotest.at (Macro with backslash in a test title):
2729 Comment out for now, as this tests neither fails nor passes
2730 reliably. Problem reported by Ralf Wildenhues.
2732 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2734 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2735 in previous change, which caused test failures.
2737 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2739 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2740 code for --enable, --disable, --with, and --without to...
2741 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2742 * doc/autoconf.texi (Package Options):
2743 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2745 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2747 Import these changes from config via gnulib:
2749 2006-11-15 Ben Elliston <bje@gnu.org>
2751 From Josselin Mouette <joss@debian.org>:

2804 first argument may also contain dots.
2806 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
2808 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
2809 benefit of platforms like Solaris+GCC where it is common to have a
2810 non-working g++ installation.
2812 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2813 and Joel E. Denny <jdenny@ces.clemson.edu>

2817 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2820 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2822 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2823 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2824 Imported from a similar patch to gnulib by Bruno Haible.
2826 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2828 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
2829 * doc/autoconf.texi (C Compiler): Document them.
2830 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
2831 New macros, taken from gnulib.

2839 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2841 * tests/torture.at (Configuring subdirectories): Do not skip
2842 Automake 1.10 nor future Automake 11.1 (sic).
2844 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2845 and Stepan Kasal <kasal@ucw.cz>
2847 Handle special characters in test case titles correctly.
2848 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
2850 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
2851 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
2852 argument. Extend to check titles printed by ./micro-suite and
2853 ./micro-suite -l and the title in micro-suite.log.
2854 (Backquote in a test title,
2855 Single-quote in a test title,
2856 Double-quote in a test title): Don't expect failure anymore.
2857 (Backslash in a test title): Put a non-whitespace character after the
2858 backslash so that Bourne shells might actually see it as an escape
2860 (Brackets in a test title,
2861 Pound in a test title,
2862 Comma in a test title,
2863 Quoted Macro in a test title,
2864 Macro in a test title,
2865 Macro with single-quote in a test title): New tests.
2866 (Macro with backquote in a test title,
2867 Macro with double-quote in a test title,
2868 Macro with backslash in a test title): New tests expected to fail.
2869 * tests/torture.at (#define header templates): M4-quote this title in
2870 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2871 The visible effect was a stray [] in the testsuite output.
2873 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2875 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2876 `trap ... 0' inside a function, for AIX sh.
2878 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2880 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2881 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2882 5363) simply issues a warning when dividing by zero at compile
2883 time. Problem reported by Elias Pipping.
2885 2006-10-26 Eric Blake <ebb9@byu.net>
2888 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2889 show effect on macros that expand with commas.
2890 Reported by Joel E. Denny.
2892 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
2893 Also work with M4 1.4.8.

2900 2006-10-25 Stepan Kasal <kasal@ucw.cz>
2902 * tests/tools.at (autom4te --force): New test, verifies that
2903 `--force' always rewrites the output file.
2905 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2907 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
2908 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
2910 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2912 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
2914 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2916 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2917 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2918 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2919 reported by Nelson H. F. Beebe for Coreutils 6.4.
2921 * tests/tools.at (autoconf --trace: user macros): Remove test
2922 for tracing multiline macros, since m4 1.4.7a uses a different
2923 way to number lines. Problem reported by Ralf Wildenhues.
2925 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2927 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2928 /dev/null since the heuristics for interactive behaviour was
2931 * bin/autom4te.in: With --force, always refresh the output
2932 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
2934 * bin/autoconf.as: Fix the verbose message at the end.
2936 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>
2938 * configure.ac (AC_INIT): Bump to 2.60c.
2941 2006-10-22 Paul Eggert <eggert@cs.ucla.edu>
2943 * NEWS: Version 2.60b.

3001 (Imported from Automake.)
3002 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3003 which incorrectly sets the mode of an existing destination
3004 directory. In some cases the unpatched install-sh could do the
3005 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3006 system. We hope this is rare in practice, but it's clearly worth
3007 fixing. Problem reported by Alex Unleashed in
3008 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3009 Also, don't bother to check for -m bugs unless we're using -m;
3010 suggested by Stepan Kasal.

3087 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3088 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3089 Use a better substitute, by inspecting the output of "ls"
3090 rather than just using ":".
3091 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3092 rather than AS_EXECUTABLE_P, since we needn't worry about
3093 non-regular files here.
3095 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3096 due to configuration hassles with this. See Tonya Underwood's report

3109 initialization which is not inherited through the environment
3110 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

3120 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3121 comment about ac_cpp_err; it was incorrect, and anyway
3122 ac_cpp_err is being removed below.
3123 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3124 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3125 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3127 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3128 with werror_flag and conftest.err and so forth. This is more
3129 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3130 and anyway the user shouldn't normally want to see this gorp logged.
3131 Problem reported by Ralf Wildenhues.
3132 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3133 empty, not 'no', since the rest of the code uses 'test -z'.

3137 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

3141 Problem reported by mwoehlke in
3142 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3144 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3145 than creating a file to use with test -x; this is much faster.
3147 2006-10-02 Bruno Haible <bruno@clisp.org>
3149 * lib/autom4te.in (Automake-preselections): Add

3154 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3155 standard error, `experr' should be used, not `expout'.

3159 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3160 fseeko testing program twice; just use the earlier result.
3161 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3162 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3163 still doesn't let the program compile.
3164 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3167 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3168 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3169 include it, without including anything else.
3170 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3172 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3177 `error.h', and include it, for a `error_at_line' prototype.
3178 Use a nonempty format string in the link test.
3179 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3180 for a declaration of wait3.

3186 can apply to constants too, and that it checks for macro defns.
3187 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

3189 values. Problem reported by Ralf Wildenhues.

3404 broken lex libraries like native ia64-hp-hpux11.22; see
3405 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

3534 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
3535 -Wundef -Werror". Problem reported by David Fang in
3536 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

3559 problems with arg script text that doesn't end in newline, and

3596 less skeptical about "volatile", after discussion with
3597 Bruno Haible on bug-gnulib.

3603 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3604 compiler complains about it, even if things works after the
3605 complaint. Problem reported by Peter O'Gorman.

3608 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3609 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3611 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3613 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3614 after -R regardless of host. Patrick Welche reports that this

3626 under AC_C_VOLATILE.
3627 (Volatile Objects): Be a little less skeptical about what
3628 "volatile" means. Derived from thoughts by Ben Pfaff in
3629 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3631 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3635 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3637 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3638 more globally, since the 2006-06-30 patch didn't suffice. Problem
3639 reported by Keith Marshall. Also, don't bother with builddir2,
3640 since it shouldn't be needed any more.
3642 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

3645 Document AC_COMPUTE_INT. Fix wrong statements on Default

3661 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3663 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3664 Require that long long int be at least 64 bits wide. C99 requires
3665 this and enough programs depend on it so we should check for it.
3666 Bruno Haible reports in
3667 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3668 that long long int is 32 bits wide with some nonstandard compilers.

3671 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3673 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3674 to a nonexistent file, so that we don't have to worry about
3675 a local site configuration that doesn't use /usr/local.
3676 Problem reported by Keith Marshall in
3677 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3679 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3681 * doc/autoconf.texi: Be more consistent about using @acronym with
3682 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3683 quite right (it talked about "OSF/Tru64", even though the
3684 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3685 and it even mentioned "OSF 4"!) and at this point there's little
3686 reason to talk about OSF any more, since it died in 1994.
3687 (Specific Compiler Characteristics): Simplify example of
3688 negative-size array.
3689 (File Descriptors): Reorder to make the text flow better.
3690 Remove joke about "appreciate the various levels"; I didn't get it.
3691 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3692 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3693 (File Descriptors, Limitations of Usual Tools):
3694 Tone down the advice against renaming or removing open files.
3695 (Limitations of Usual Tools): Add a new section, on 'rm'.
3697 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3699 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3700 -lXt in LIBS, idea from Karsten Hopp; this was due since
3703 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3704 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3705 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3706 (which belong to Xt, not X itself). See Debian bug 327655.
3708 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3710 * configure.ac (AC_INIT): Bump to 2.60a.
3713 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3717 * configure.ac, NEWS: Update.

3721 * config/texinfo.tex: Sync from upstream.
3723 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3724 quadrigraph correctly in traces.
3726 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:

3730 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3732 * doc/autoconf.texi (Changed Directory Variables): New node,
3733 to document the whole `datarootdir' business a bit better.
3735 * tests/torture.at (datarootdir workaround): Extend test.
3736 Prompted by report by Alexandre Julliard.
3738 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3740 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3741 when using default mode of IBM C 6 for AIX. Problem and two-line
3742 fix reported by Larry Jones.
3744 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3746 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3747 about literal '${datarootdir}' if a definition is found in the
3750 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3752 * NEWS: Use "M4" rather than "m4" when appropriate.
3753 Problem reported by Eric Blake.
3754 * doc/autoconf.texi: Likewise.
3755 Use @acronym around BSD, GCC, and GNU when appropriate.
3756 (Why GNU M4): Renamed from "Why GNU m4".
3757 (Redefined M4 Macros): Mention that Posix
3758 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3759 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3762 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3764 * bin/autom4te.in (handle_output): Do not forbid the empty
3766 * tests/tools.at (autoconf: the empty token): New test.
3768 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3770 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3771 calls, so that we do not care whether they are LIFO or FIFO;
3772 in the m4_wrap, do not check which diversion is the topmost
3773 one, just check that the stack is balanced at the end.
3774 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3775 base diversion forever--pop the previous diversion before
3776 opening the new one; consequently, remove the m4_wrap call.
3777 * lib/autotest/general.m4 (AT_INIT): Likewise.
3778 * tests/m4sugar.at: Do not use
3779 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

3782 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3784 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3785 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3786 Rework example of m4wrap token-pasting trouble so that it doesn't
3787 care whether it's LIFO or FIFO.
3788 Fix some "contrary to"s that are awkward in English.
3790 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3792 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3793 to `yes' instead of `int$1_t' if the type is found, for more
3794 consistent configure output (where $1 is the number of bits).
3795 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3796 Suggested by Bruno Haible.
3798 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3799 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3800 with system headers. Report by Bruno Haible.
3802 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3804 * config/config.guess, config/config.sub: Sync from upstream.
3806 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3807 in order to avoid picking up an older installed frozen m4sh.m4f.
3808 Besides an outdated shell startup, this could have been created
3809 by an earlier M4 version with incompatible frozen file format.
3811 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3813 * README: Recommend m4 1.4.4 instead of 1.4.3..
3814 * doc/autoconf.texi: Likewise.
3815 (Special Chars in Names): Say that $(.FOO) is portable, as
3816 suggested by Stepan Kasal.
3817 (Installation Directory Variables, Build Directories):
3818 (Automatic Remaking, Subdirectories, Fortran Compiler):
3819 (Making testsuite Scripts, Defining Directories):
3820 Quote variable usages better.
3821 (Making testsuite Scripts): Add clean-local rule to makefile
3822 snippet, by Eric Blake.
3823 (Installation Directory Variables): Fix table item font.
3824 Reword slightly to clarify. Generalize advice about
3825 not using special characters to include all file-related
3826 vars, not just VPATH.
3827 (Special Chars in Variables): Warn about special characters in
3829 (Assignments): Clarify default-value example as suggested by
3831 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3832 (Special Shell Variables): Note leading ./ or ../, as suggested
3834 (Limitations of Builtins): Under cd, warn about CDPATH.
3835 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3838 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3840 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3841 `@var', for texi2html.
3842 (Systemology): Some more word wrapping, for DVI output.
3843 (autom4te Invocation): The short option for `--melt' is `-M',
3846 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3848 * doc/autoconf.texi: More formatting and English tweaks,
3849 many suggested by Ralf Wildenhues.
3850 Reword to avoid "@code{...}'s" and the like, since it's ugly
3851 with Emacs info mode. discontents -> woes.
3852 Put a few "will"s back. time stamp -> timestamp.
3853 side-effect -> side effect.
3855 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3857 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3858 Warn about $@ not persisting. Problem reported by Julien Danjou in
3859 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3860 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3861 Mention other special chars, too.
3863 2006-06-14 Eric Blake <ebb9@byu.net>
3865 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3867 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3869 * doc/autoconf.texi: Some systematic minor improvements, as
3870 follows. Use "makefile" when talking about makefiles
3871 generally (which might be named "makefile" or "Makefile" or even
3872 "foo.mk"), "Makefile" when talking about a specific makefile
3873 called "Makefile". This unclutters the text from weird quotes
3874 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3875 values" rather than "@var{foo}s" and similar constructs containing
3876 "}s". Use "Make rules" rather than "Makefile rules". Minor
3877 English-language improvements. Change the prefix "sub-" to "sub"
3879 Put blank lines around examples more consistently.
3880 Avoid "rather" and "very" as intensifiers.
3881 Avoid "will" as an auxiliary.
3882 (Limitations of Make): Split this node into....
3883 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3884 (Leading _ in Macro Names, Backslash-Newline-Newline):
3885 (Backslash-Newline Comments, Long Lines in Makefiles):
3886 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3887 (obj/ and Make, make -k Status, VPATH and Make):
3888 (VPATH and Double-colon, $< in Explicit Rules):
3889 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3890 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3891 New nodes, resulting from splitup of Limitations of Make.
3892 All cross-references changed. Raise the top node from
3893 a section to a chapter, and all subnodes accordingly.
3894 Redo the introductory wording to match the new organization.
3895 (Installation Directory Variables): Use an example that is
3896 closer to what Autoconf actually does. Mention that VPATH's
3897 value should not contain metacharacters or white space.
3898 (Fortran Compiler): Fix a VPATH bug in an example.
3899 (Leading _ in Macro Names): Mention that this problem is no longer
3900 of practical concern.
3901 (VPATH and Make): Reword the advice to make it clearer
3902 that Autoconf and Automake support VPATH in non-GNU make, but
3903 many packages have bugs in this area.
3904 ($< in Explicit Rules): Refer to Build Directories rather
3905 than using a (non-VPATH-safe) example.
3906 (Automatic Rule Rewriting): Mention the sort of disaster that
3907 can ensue with Solaris-style rule rewriting with VPATH.
3909 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3911 * doc/install.texi (Compilers and Options): Weaken the
3912 suggestion to use GNU make for VPATH builds.
3914 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3915 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3917 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3918 in regular expression.
3920 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3922 * doc/autoconf.texi (Installation Directory Variables):
3923 Drop extra @samp from `@table @samp' item.
3924 (Limitations of Usual Tools): Comment fix.
3925 Do not nest @samp just to point to other table items.
3926 (Writing testsuite.at) <AT_CHECK>: The second argument to
3927 `@dvar' is already @samp'ed.
3928 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3929 do not use @var in the second argument.
3931 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3933 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3934 $as_shell.exe too. Problem reported by Andreas Buening in
3935 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3937 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3939 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3940 `unused variable' compiler warning, for `-Wall -Werror'.
3941 Reported by Jaap Haitsma in
3942 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3944 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3946 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3947 case the compiler dumps core. Problem reported for
3948 OpenServer 5.0.7 by Tim Rice in
3949 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

3953 2006-06-06 Tim Rice <tim@multitalents.net>.
3955 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3956 "ERROR" only shows up in "make check" output if there is an

3980 * config/texinfo.tex: Sync from upstream.
3982 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3983 seen, invoke libtoolize with `--ltdl' argument.
3984 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3986 Suggested by Eric Blake.
3988 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

3998 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4000 * doc/autoconf.texi: Modernize some of the references to Solaris.
4002 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4004 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4005 message issued by AC_REQUIRE.
4006 * tests/m4sugar.at: Check m4_require's error message.
4007 * tests/base.at: Check AC_REQUIRE's error message.
4008 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4010 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4012 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4013 `expout' as the last parameter.
4014 * tests/tools.at: Adapt to the above change.
4016 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4018 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4019 information about race-free implementations of mkdir.

4028 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4030 * NEWS: GNU make now recommended for VPATH builds.
4031 Mention that some macros are now documented to be obsolescent.
4032 * doc/autoconf.texi:
4033 Prefer "current" to "modern" to describe
4034 currently-used (albeit perhaps old-fashioned) hosts.
4035 Mention which ancient features no longer need to be worried about.
4036 setgid -> set-group-ID
4037 setuid -> set-user-ID (these are the Posix terms)
4038 Fix some misuses of "only".
4039 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4040 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

4049 (Installation Directory Variables): shall -> should
4050 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4051 Mention that it's now safe to use 3 and 4.
4052 (Limitations of Usual Tools): cp -r is now specified by Posix.
4053 Omit longwinded and obsolescent discussion of cp -f.
4054 Modernize discussion of expr, ls.
4055 (Limitations of Make): Modernize discussion of VPATH builds.
4056 Mention $? as a workaround in some cases.
4057 * doc/install.texi (Basic Installation):
4058 Mention "./configure; make; make install" first. Be more
4059 specific about why this file is generic. Remove unnecessary
4060 parens. Remove misleading "only". Remove obsolete advice
4061 about csh. Don't say "configure" takes awhile; say it
4062 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4063 and CC=c99 rather than CC=c89, as these are blessed by current
4064 Posix. Recommend GNU make if doing a VPATH build.
4066 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4068 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4069 examples involving shell prompts.
4071 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4072 and Paul Eggert <eggert@cs.ucla.edu>
4074 * doc/autoconf.texi (Here-Documents): Add details about the
4075 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4076 use "here-documents" instead of "here documents".
4078 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4080 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

4084 * doc/autoconf.texi (File System Conventions): Warn about ":"
4085 anywhere in directory names.
4087 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4089 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4090 about quoting the case statement, just in case.
4091 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4092 was fixed in ksh93g; reported by Ralf Wildenhues.
4094 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4096 * doc/autoconf.texi (System Services): Do not document

4106 argument with leading hyphen. Problem reported by Paul Eggert.
4108 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4110 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4111 about quoting ac_try: quote all of it, if any of it seems suspicious.
4112 This means we don't have to worry about ${ or sed any more.
4113 Also, double-quote the case statement, to work around misuses via
4114 underquoting as reported by Ralf Wildenhues in
4115 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4116 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4117 undocumented and dangerous macro.

4129 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4130 since evidently some packages rely on the old, broken behavior.
4131 Problem reported by Ralf Wildenhues in
4132 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4133 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4134 pre-2006-05-26 definitions, but leave in the comments that
4135 these macros are dangerous and should not be used.
4136 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4137 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4138 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4139 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4140 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4142 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4144 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4145 the use of 'tr', since this is our only use of 'tr'.
4147 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4148 and Paul Eggert <eggert@cs.ucla.edu>
4150 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4151 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4153 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4155 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4156 the output file in the `${datarootdir}' test.
4158 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4159 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4161 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4162 mention of `datarootdir' in the input file(s), but literal
4163 `${datarootdir}' in the output file, and we haven't warned yet,
4164 then warn as well: the user may have (erroneously) used
4165 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4166 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4167 * tests/torture.at (datarootdir workaround): Extend this test.
4170 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4171 and Paul Eggert <eggert@cs.ucla.edu>
4173 * doc/autoconf.texi (autoheader Invocation): The first argument to
4174 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4175 alternatives and clear up the language a bit.
4177 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4179 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4180 ac_config_guess, ac_config_sub, ac_configure.
4181 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4182 Fix typo that prevented an unnecessary space from being removed.
4183 Problems reported by Ralf Wildenhues in:
4184 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4186 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4188 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4189 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4190 Don't use the term "thread-safe" to talk about mkdir race
4191 conditions, since the problem is more a process than a thread
4192 issue. Problem reported by Stepan Kasal in:
4193 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4194 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4195 the test for 'install' more closely. Look at MKDIR_P first.
4196 Look in the PATH, and at /opt/sfw/bin.
4197 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4198 Don't bother to try mkdir -p, since we already check mkdir --version;
4199 just look at the version number. (There's no easy way to check
4200 for race-free implementations.)
4201 * tests/tools.at (autoconf: subdirectories): Adjust to above
4202 changes, since MKDIR_P now might end in "/mkdir -p".
4204 * doc/autoconf.texi (autoheader Invocation): Mention that the
4205 first arg of AC_DEFINE_UNQUOTED must be a literal.
4206 Problem reported by Ben Pfaff in
4207 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4209 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4210 * doc/autoconf.texi (Special Chars in Variables): New section.
4211 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4212 (Installation Directory Variables): Quote $(datadir) better.
4213 (Limitations of Builtins): Describe some of eval's trickiness.
4215 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4216 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4217 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4218 in front of every arg, not just trailing args. Quote apostrophes.
4219 (_AC_EVAL_ECHO): New macro.
4220 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4221 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4223 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4224 exposed by quoting of eval argument. Put the command on line line
4226 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4227 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4228 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4229 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4230 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4231 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4232 Use eval more safely.
4233 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4234 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4236 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4237 lines, exposed by quoting of eval argument.
4239 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4240 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4242 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4243 initialization of `ac_cv_exeext', do not override it if it was
4244 already set, unless it was set to `no', for compatibility with
4245 Autoconf-2.13, and comment this.
4246 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4247 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4248 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4249 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4250 Document that this test may be overridden by setting
4253 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4255 Revert these two patches:
4257 2006-04-06 Eric Blake <ebb9@byu.net>
4258 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4259 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4262 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4263 Clean up _AC_COMPILER_EXEEXT* macros.
4264 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4265 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4266 ac_file to the name of the default output file and call
4267 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4268 initial `rm' of the candidate files...
4269 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4270 the same list in subsequent `rm' calls, and for the temporary
4271 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4272 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4273 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4274 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4275 no longer needed) by libtool. Make it a cache check.
4276 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4277 copied here by mistake.
4278 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4279 _AC_COMPILER_EXEEXT.
4280 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4281 _AC_COMPILER_OBJEXT directly.
4282 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4284 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4286 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4287 Fix description of how the buggy `sed' works.
4289 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4293 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4294 ENOLCK. Only mention `make -j' when applicable. Only raise
4295 fatal errors when `make -j' is involved. Improve error message.
4297 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4299 * doc/autoconf.texi (Here-Documents): We now know more about
4300 the variable expansion in here documents bug.
4301 Thanks to Tim Rice and Stepan Kasal.
4303 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4304 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4306 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4308 * tests/autotest.at (Multiline command from M4 expansion):
4309 No failure to be expected if the shell quotes newlines in
4310 commands in the `set -x' output. Report by Tim Rice.
4313 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4315 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4316 expansion in the here-documents used by config.status, as that
4317 runs afoul of the Korn shell version M-12/28/93d bug described in
4318 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4319 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4320 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4322 2006-05-23 Jim Meyering <jim@meyering.net>
4324 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4325 Fix typo introduced with 2006-04-02 change. It reversed the sense
4328 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4330 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4331 ac_dB slightly, to save bytes in the script.
4332 Max out at 50 lines, rather than 96; this is more likely
4333 (though not guaranteed) to avoid obscure 'sed' failures.
4335 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4337 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4338 `tr -d -' as bad option argument. Work around this by deleting
4339 an unrelated character.
4340 Report by Tim Rice <tim@multitalents.net>.
4342 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4343 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4344 Stepan Kasal <kasal@ucw.cz>
4346 * doc/autoconf.texi (Particular Programs): Do not promise that
4347 we always prefer the GNU version of the program, and that we
4348 search according to PATH; both rules can have exceptions.
4349 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4350 AC_PROG_SED. Move descriptions of limitations
4351 to the Limitations of Usual Tools section.
4352 (Limitations of Usual Tools) <sed>: Mention script length
4353 limitations with Solaris /usr/ucb/sed.
4354 <grep>: Fix wording for empty alternative. Mention that -c and
4355 -l should not be combined, and that -E and -F should not be
4358 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4359 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4361 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4362 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4364 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4366 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4367 AC_DEFINE is now passed to m4_pattern_allow.
4368 * NEWS: Mention that; likewise for AC_SUBST.
4369 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4370 the parameter to m4_pattern_allow.
4371 * tests/tools.at: Add a check for that.
4373 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4375 * lib/autoconf/status.m4: Fix typos.
4377 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4379 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4380 only the files that this macro generates.
4382 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4384 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4385 the HP-UX sed limitation of 99 commands, labels do not count.
4386 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4388 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4390 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4392 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4393 Import the following fix from coreutils:
4395 2006-01-13 Jim Meyering <jim@meyering.net>
4397 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4398 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4399 not double-quote uses of that variable, to accommodate the rare
4400 case in which getmntent is available in none of the libraries
4401 checked. This happens at least on FreeBSD 5.0.
4403 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4405 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4406 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4407 some other programs unwisely rely on these undocumented vars.
4408 But put in warning comments about them.
4409 Problem reported by Ralf Wildenhues in
4410 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4411 * NEWS: Document that these variables are intended to go away.
4413 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4415 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4416 and set the language to C++ (analogous to the equivalent Fortran
4419 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4420 * doc/autoconf.texi (C++ Compiler): Document it.
4421 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4424 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4426 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4427 that caused config.status to generate 100-command sed scripts; the
4428 portable limit is 99.
4430 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4432 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4433 variable `ac_d' instead of `d' to avoid infringing namespace.
4434 Report by Ralf Menzel.
4436 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4438 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4439 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4440 * tests/tools.at (autoconf: subdirectories): New test, taken from
4441 the corresponding problem report by Ralf Wildenhues in:
4442 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4444 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4445 Quote some uses of shell variables if they might suffer unexpected
4446 globbing. This doesn't fix all instances of quoting problems that
4447 I found, just the easy ones that look safe.
4448 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4449 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4450 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4451 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4452 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4453 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4459 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4461 * bin/autoreconf.in ($help): Reword according to the manual.
4462 Suggested by Olly Betts.
4464 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4465 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4467 * bin/autoreconf.in: Pass the directory argument to
4468 `require_configure_ac'. Fix comment.
4469 * tests/torture.at (Configuring subdirectories): Expose this.
4470 Reported by Olly Betts.
4472 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4474 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4475 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4476 Automake as follows:
4478 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4479 `$configure_in' instead of `configure.in', to preserve
4480 directory component.
4482 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4484 * config/config.guess, config/config.sub, config/texinfo.tex,
4485 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4487 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4489 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4490 test for C99 conformance; (bool) 0.5 is an integer constant
4491 expression, but (bool) -0.5 is not. Problem reported by Fedor
4492 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4494 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4496 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4497 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4498 Warn about obsolete install-sh files. Remove stray sentence
4499 fragment and fix cross reference.
4500 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4501 install -d; this undoes the 2006-05-10 change.
4502 (MKDIR_P): Mark with AN_MAKEVAR.
4503 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4504 that we don't require $INSTALL to be thread-safe. Move comments
4505 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4506 of AC_PROG_INSTALL. Output a message saying that we're checking
4507 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4508 MKDIR_P instead of AC_SUBST.
4509 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4510 Special magic for MKDIR_P, too.
4511 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4513 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4515 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4517 Sync from Automake, as follows:
4519 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4520 * config/install-sh: Initialize IFS, so field splitting isn't
4522 * config/mkinstalldirs: Likewise.
4523 * config/missing: Remove superfluous quotes. Replace all uses of
4524 `[' by `test', for consistency, and for..
4525 * config/missing (sed_minuso, sed_output): New variables.
4526 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4527 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4528 Fixes `missing' to detect `--output' for help2man. Fixes
4529 PR automake/483. Report by Dennis J. Linse.
4530 (autom4te): Document in `missing --help'.
4532 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4534 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4535 * config/install-sh: Don't use 'path' to talk about file names,
4536 as per GNU coding standards. Close a race condition reported by Ralf
4537 Wildenhues and Stepan Kasal. There is still a race condition
4538 on hosts that predate Posix 1003.1-1992, but we can't help this.
4539 Don't mishandle weird characters like space on pre-Posix hosts.
4540 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4541 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4542 AC_PROG_MKDIR_P from AS_MKDIR_P.
4543 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4544 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4545 earlier editions are not (including Automake 1.8.3).
4546 Do not suggest mkinstalldirs for thread-safety.
4547 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4548 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4549 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4550 presence of special characters and race conditions.
4551 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4552 in Autoconf's name space.
4554 2006-05-10 Bruno Haible <bruno@clisp.org>
4555 and Paul Eggert <eggert@cs.ucla.edu>
4557 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4558 from Automake with minor changes.
4559 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4561 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4563 * config/install-sh: Update to Automake CVS version, as follows:
4564 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4565 * lib/install-sh: Simplify the expr implementation of dirname.
4566 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4567 * lib/install-sh: Handle --, and diagnose unknown options.
4569 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4571 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4572 `./autom4te' to create `./testsuite', since the `all' target
4573 will ensure its presence, but `installcheck' should not create
4574 the uninstalled wrappers.
4576 * tests/torture.at (Unusual Automake input files): Skip if we
4577 detect automake < 1.8.
4579 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4581 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4582 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4583 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4586 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4588 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4589 munge (multiple) white space and other oddities.
4590 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4591 single quotes in variable assignment.
4592 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4593 and similar failures by adding multiple spaces, tabs, and other
4595 Report and different test suggested by Francesco Romani
4596 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4598 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4599 single quotes, we only need to search for single quotes; this
4600 both simplifies the search pattern, and makes us less
4601 susceptible to `echo' variations for arguments not containing
4603 (_AC_ARG_VAR_VALIDATE): Likewise.
4605 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4607 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4608 `$*' and IFS concatenation issue with traditional shells and
4609 bash-2.04. Report by Seanster@Seanster.com.
4611 2006-05-03 Bruno Haible <bruno@clisp.org>
4613 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4614 precisely which Mac OS X versions have the od problem.
4616 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4618 * doc/autoconf.texi: Use @option systematically.
4620 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4621 and Bruno Haible <bruno@clisp.org>
4623 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4625 (Integer Overflow): Mention the special case of integer division
4628 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4630 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4631 traditional shells like the Solaris one that do not use the
4632 first IFS character for assembling `$*'.
4633 Prompted by a related report from autoconf_bug@nro.ca.
4635 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4636 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4638 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4639 Mention more problems with the -e option.
4641 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4644 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4646 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4647 in URLs to improve DVI formatted output (requires texinfo 4.6).
4648 (System Services, Systemology, Shellology): Likewise.
4649 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4652 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4654 (Runtime): Fix macro argument names to match description:
4655 `action-if-found' -> `action-if-true' and similarly.
4656 (Obsolete Macros): Likewise.
4657 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4658 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4659 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4661 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4663 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4666 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4669 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4671 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
4672 /bin/sh set unsorted output.
4673 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
4674 * tests/local.at: Likewise.

4681 (Writing Test Programs): Fix some langauge. Recommend exiting
4682 with status 1, not merely nonzero. Clarify exit declaration.
4683 (Run Time): Move C exit status stuff to new Exiting Portably section.

4689 * bin/autoconf.as (me): Replace by as_me.
4691 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4693 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4694 since as_me isn't set yet.
4696 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4698 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4699 a few minor bugs in this area.
4701 * doc/autoconf.texi (Programming in M4sh): Comment out the
4702 documentation of AS_BASENAME, for now.
4703 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4704 (Limitations of Builtins) <basename>: Do not refer to
4706 * bin/autoconf.as (me): Don't use AS_BASENAME.
4707 (dir): Remove the unused variable.
4708 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4709 AS_DETECT_REQUIRED. All uses changed.
4710 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
4712 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

4715 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4716 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4717 (_AS_DIRNAME_PREPARE): Likewise.

4719 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4720 (AS_DIRNAME): Use "dirname --".
4722 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4724 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4725 of "run time" and "run-time" changed to "runtime", for consistency.
4726 * lib/autoconf/fortran.m4: Likewise (in comment).
4727 * lib/autoconf/functions.m4: Likewise.
4728 * lib/autoconf/general.m4: Likewise.
4729 * lib/autoconf/headers.m4: Likewise.
4731 * doc/autoconf.texi (Run Time): Document the exit status situation
4732 with more accuracy and detail.
4734 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4736 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4737 Archive is not officially `GNU' any more. Update URL.
4738 (Defining Directories): Likewise
4739 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4741 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4743 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4744 newline from the `trap' code to finish `config.log'; the NetBSD
4745 /bin/sh resets the exit status after an empty command, as
4746 documented in doc/autoconf.texi.
4747 Reported by Dalibor Topic <robilad@kaffe.org>.
4749 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4751 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4752 Suggested by Bruno Haible.
4754 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4756 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4757 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4758 Instead, just list the shells that we know work.
4759 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4760 changed. Be more cautious about the _cv_ variable.
4761 * tests/tools.at (Syntax of the shell scripts): Check the
4762 _cv_ variable once, at first, to avoid an internal autoconf error
4763 when sh -n does not work.
4765 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4767 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4769 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4771 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4772 use ">&-" since we're only 99.999% sure that this is portable,
4773 and since the MinGW bug is fixed in a different way.
4774 * lib/autotest/general.m4 (AT_INIT): Likewise.
4776 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4778 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4779 before opening config.log, to avoid hitting a bug on MinGW.
4781 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4783 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4784 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4785 This works around a MinGW bug reported by Eric Paire.
4786 Make sure that all writes to the log file append to it,
4787 rather than possibly losing data.
4788 * lib/autotest/general.m4 (AT_INIT): Likewise.
4790 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4792 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4795 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4799 * configure.ac (AC_INIT): Bump to 2.59d.
4801 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4805 * Makefile.maint (news-date-check): Do not require a leading `*'
4806 before the release date in NEWS.
4808 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4809 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4811 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4812 the instantiated file do not contain the string 'datarootdir'
4813 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4814 @mandir@, replace the reference '${datarootdir}' by the value.
4815 * tests/torture.at (datarootdir workaround): New test.
4816 * NEWS: Advertise this temporary fixup.
4817 Based on a patch by Bruno Haible, reported and analyzed by
4818 Paul Eggert and Noah Misch.
4820 2006-04-12 Eric Blake <ebb9@byu.net>
4822 * tests/autotest.at (Debugging a failed test): Fix comment.
4824 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4826 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4827 all the changes since 2006-04-07.
4829 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4831 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4832 succeeded, but `ln -s file dir' failed, take care to remove the
4833 leftover target before the next test, to prevent its spurious
4834 failure; also make sure `ln file dir' works before selecting it.
4835 Thanks to Keith Marshall for pointing this out.
4838 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4839 assignments in `at_debug_args', so that we put them correctly
4840 in the `run' script.
4841 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4842 Reported by Eric Blake.
4844 2006-04-11 Eric Blake <ebb9@byu.net>
4846 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4847 top-level tests after micro-suite has been run. Used in...
4848 (Debugging a successful test, Debugging script and environment),
4849 (Debugging a failed test): ...these new tests. The first of these
4851 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4852 macro, split out from...
4853 (AT_INIT): ...here, so that using -d also generates a run script.
4854 Document that -d inhibits top-level logging.
4855 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4856 inhibits top-level logging; debug scripts are created.
4858 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4860 * tests/autotest.at (Empty test, Empty check): New test to check it.
4862 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4865 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4867 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4868 the files if a problem appears. Make the empty *.at files
4869 read-only, too. Proposed by Ralf Wildenhues.
4871 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4873 * config/Makefile.am: Add comment to force updated Makefile.in.
4875 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4876 space only patch to this file, this patch causes the Makefile.in
4877 files that include freeze.mk to be updated, and thus have a
4878 newer time stamp again, which in turn makes a pristine CVS
4879 checkout have correct time stamps.
4881 * Makefile.maint (cvs-sv): New macro, to be used..
4882 (config.guess-url_prefix, config.sub-url_prefix)
4883 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4884 point to CVS text checkout of Gnulib files.
4885 (copyright-check): Bump current year.
4886 (announcement): Do not hard-wire `./announce-gen'.
4887 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4889 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4891 (wget_files): Update config.guess, config.sub, texinfo.tex by
4892 `wget-update', now that their URLs work again.
4894 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4896 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4897 Problem noted by Paul D. Smith.
4899 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4901 * doc/autoconf.texi: Remove unused words from word list.
4902 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4903 .x-sc_trailing_space: New files.
4905 * doc/standards.texi: Sync from gnulib.
4907 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4908 `LIBOBJDIR' as experimental.
4910 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4911 with a target directory; it's internally implemented as `cp'
4912 anyway, but since Autoconf advertises the possibility to use
4913 a target directory when LN_S is `ln -s', we need to find out.
4914 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4915 analyzed by Keith Marshall <keith.marshall@total.com>.
4919 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4921 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4922 confdefs.h as-is. In general, if it has backslash-newline or the
4923 like, then it doesn't work either to sort or to remove empty
4926 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4928 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4930 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4932 * lib/autom4te.in (Automake-preselections): Preselect
4935 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4937 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4938 apostrophe within a single-quoted string, as this is the usual
4939 tradition and is easier to read than '"'"'. Don't rely on the
4940 shell treating "$/" like '$/'. Use a more-consistent indenting
4943 2006-04-09 Eric Blake <ebb9@byu.net>
4945 * tests/autotest.at (Backquote command substitution),
4946 (Multiline backquote command substitution): Remove mistaken
4947 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4949 (Parenthetical command substitution, Multiline parenthetical
4950 command substitution): here.
4952 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

4984 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4985 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4986 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4987 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

5014 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5016 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5017 of the warning introduced by the 2001-08-28 change.

5027 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5029 Revert the patch from 2006-04-01 and only improve
5030 _AS_DETECT_BETTER_SHELL:
5032 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5033 skip nonexistent directories.
5034 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5035 only shell candidates which exist.
5036 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5037 * lib/autotest/general.m4 (AT_INIT): No need to give three
5038 parameters to _AS_PATH_WALK.
5040 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5041 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5043 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5044 distinguish m4sugar macros.
5045 * tests/tools.at (autoupdating with aclocal and m4_include):
5046 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5047 test case by Noah Misch <noah@cs.caltech.edu>.
5049 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5051 Revert my change from 2006-03-17, in other words:
5052 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5054 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
5055 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
5058 2006-04-07 Eric Blake <ebb9@byu.net>
5060 * doc/autoconf.texi (Programming in M4sh): Document that
5061 AS_MKDIR_P exits the script on failure.
5062 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5064 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5066 * config/elisp-comp, config/install-sh, config/mdate-sh,
5067 config/missing, config/mkinstalldirs: Sync from Automake.

5081 Eric Blake <ebb9@byu.net>,
5082 Paul Eggert <eggert@cs.ucla.edu>,
5083 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5085 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5086 whether `set' quotes correctly: redirect stderr of the tested
5087 `set', and use a subshell, for Ultrix; use `sed' instead of
5088 `grep' for zsh `set' which may write binary output; match only
5089 at the beginning of a line, to avoid false positives.
5090 In order to avoid false positives by unrelated variables with
5091 multiline content, put the dump algorithm in a subshell and
5092 unset all variables containing newlines (except some which are
5093 special to the shell). Warn about cache variables that are
5096 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5098 * config/config.guess, config/config.sub, config/texinfo.tex:
5101 * tests/mktests.sh: Reword comments.

5138 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5139 ac_config_<foo>s again, sometimes normalized, sometimes not.
5140 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5141 (AC_CONFIG_COMMANDS): Do not do so here.
5142 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5143 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5144 2005-07-25 rewrite. Noticed by Noah Misch.
5146 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5147 _AC_PRESERVE_HELP_ORDER, ...
5148 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5150 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
5151 inside m4_expand_once; it is redundant.
5153 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
5154 for --help from Cygnus `configure.'
5156 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5169 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
5170 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
5171 * doc/autoconf.texi (Help Formatting): New node.
5172 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
5174 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5176 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
5177 lib/autoconf/specific.m4, lib/autoconf/status.m4,
5178 lib/autoconf/types.m4, lib/autotest/general.m4,
5179 tests/mktests.sh, tests/torture.at: White space cleanup:
5180 remove some SPACE before TAB, or add quoting ('' or @&t@).
5182 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
5184 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
5186 2006-04-05 Eric Blake <ebb9@byu.net>
5188 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
5189 empty test suite works.
5190 * tests/autotest.at (Empty test suite): Remove xfail.
5192 2006-04-05 Noah Misch <noah@cs.caltech.edu>

5195 TAGS to ac_config_<foo>s.
5196 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
5197 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
5198 normalizing it, consistent it with previous releases.
5199 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
5201 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5203 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5204 Use simplified args that Eric Blake originally suggested.
5206 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5208 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5209 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5210 Use 'comm' rather than N instances of grep; this also fixes a bug
5211 whereby substrings were incorrectly matched, causing us to not
5212 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5213 (exclude_list): Exclude empty macros.
5214 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
5216 Use awk rather than grep -E or egrep, to avoid
5217 portability problems with regular expressions containing newlines.

5226 a subdirectory subject to Cygnus `configure'.
5227 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
5229 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
5230 report request when we have no AC_PACKAGE_BUGREPORT.
5232 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5236 * tests/mktests.sh: Update copyright year in the header of the
5239 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
5240 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
5241 typedef'ed restricted pointer, to catch a compiler bug on
5242 HP-UX 11.x, and fix warnings so it passes with -Werror.
5243 (_AC_PROG_CC_C99): Likewise.
5244 Reported by Albert Chin <china@thewrittenword.com>.

5387 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
5388 switch all of them on and of when necessary. Fixes the bug when

6111 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6112 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6113 make its content writable before removing it. Remove an errorneous

6142 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6144 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6145 calls, so that the final expansion of this macro is shorter.
6146 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6147 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6148 the cleanup there. Use AS_VAR_* macros, to be more general.
6149 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.

6178 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6179 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

6200 Update limitations about when to call AC_CONFIG_HEADERS.
6201 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6202 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6203 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6204 ``Configuration Actions''; fix their index entries.
6206 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6207 options correctly. Process N-M as M-N if M is smaller than N.
6208 Process ranges correctly so that N-N will run only N.
6209 Sort and uniquify the tests that will be run. If there is more
6210 than one test, reinsert the banners for the tests.
6211 * tests/autotest.at (Keywords): Unmark XFAIL.
6213 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6215 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6216 before passing the macro name to AH_TEMPLATE.
6218 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6219 now opens log after option processing; in particular, --version
6220 and --help do not touch config.log.

6237 Prepend to LIBS, not append, in examples.
6239 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6241 When building in place, set srcdir="."; suggested by Tim Van Holder.
6243 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6244 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6245 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6246 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6247 does not mean "no --srcdir option".
6249 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6263 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6265 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

6281 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6283 Rewrite substantial part of lib/autoconf/status.m4.
6284 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6285 and CONFIG_COMMANDS are not processed in four separate loops.
6286 Instead, there is one main loop. This alows that the common code
6287 is expanded only once, thus config.status (and configure) is smaller.
6289 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6290 the AC_LIST_FILES and cousins macros are no longer used.
6292 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6293 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6294 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6295 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6296 contain the initialization, nor the for loop, nor the associated
6297 commands; all these go to ...
6298 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6299 _AC_OUTPUT_CONFIG_STATUS.
6300 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6301 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6302 (_AC_OUTPUT_FILE): The creation of the sed script ...
6303 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6304 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6305 _AC_OUTPUT_MAIN_LOOP.
6306 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6307 _AC_CONFIG_COMMANDS): Use ...
6308 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6309 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6310 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6311 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6312 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6313 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6315 (_AC_CONFIG_UNIQUE): Update.
6316 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6317 Replaced by this ...
6318 (_AC_LIST_TAGS): ... new common macro.
6319 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6320 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6321 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6322 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6323 this didn't belong to the `config commands' section.
6324 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6325 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6326 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6327 to the `config commands' section either.
6328 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6329 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6331 ... and many changes to the comments nearby.
6333 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6334 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6335 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6336 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6337 (#define header templates): The comment at the top of the generated
6338 header now includes the name(s) of the source file(s).
6340 Several unrelated small changes:
6342 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6343 parameter to AC_DIAGNOSE.
6344 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6345 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6346 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6347 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6349 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6350 in AC_OUTPUT doesn't double-quote it either.
6351 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6354 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6356 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6357 versions of Portland Group compiler produce single- and double-quoted
6358 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6359 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6361 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6363 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6364 This is a corrected version of yesterday's patch.
6366 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6368 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

6372 ac_cv_build_alias to ac_build_alias.
6373 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6375 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6376 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6377 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6378 (AC_ARG_VAR): ... here.
6379 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6382 Keep a list of all precious variables and process them with one simple
6383 for loop, instead of expanding all commands, or, OTOH, complicated
6384 processing of output of "set".
6385 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6386 variable names in new macro...
6387 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6388 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6389 a loop to assign all ac_env_* and ac_cv_env_* variables.
6390 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6392 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6393 its value to shell variable ac_precious_vars and call
6394 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6395 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6396 _AC_ARG_VAR_VALIDATE.
6398 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

6416 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6417 They are generated by the Tru64 v5.1B shell.

6426 Fix cases when the varsions of Autoconf and Autotest don't match.
6427 Reported by Noah Misch.
6428 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
6429 at_top_builddir, for compatibility with older autotest.
6430 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
6431 is not set, use at_top_builddir, for compatibility with older
6432 versions of autoconf.
6434 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6436 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
6437 Problem reported by Patrick Welche.
6439 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
6441 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6442 sed substitution command, so that we allow | in program prefixes
6443 and program suffixes. (& is a problem anyway; we're not fixing
6445 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
6446 configure_input, top_builddir, srcdir, etc.
6447 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6448 PATH_SEPARATOR in AUTOTEST_PATH.
6450 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6458 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6459 directories with weird names. Apparently some people like living
6460 on the edge. However, improve the test that "pwd" actually does
6461 report a name for the working directory.

6481 document to output the default config_* lists to config.status.
6482 Don't recognize option --file, if the functionality is not there.
6483 Likewise for --header; moreover, recognize --he and --h as shortcuts
6484 for --help in that case.
6486 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6487 matches the order of execution. No code changed.

6511 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6512 the directory specific variables; but don't call it for configure_input.
6514 2005-06-28 Derek Price <derek@ximbiot.com>
6516 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6519 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
6521 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
6522 directory have inherent problems with special characters like spaces,
6523 due to limitations in Make syntax. Problem reported by Alexandre
6525 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
6526 Also, fix Tru64 porting problem with shell patterns,

6539 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
6540 variable into diagnostic. Make the diagnostic an error, not a warning,
6541 because we really don't support spaces and suchlike in dir names.
6542 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6543 Don't worry about backslashes in srcdir; it can't happen now.

6587 * doc/autoconf.texi:
6588 Don't mention Solaris versions so much, if a
6589 problem is common to all extant versions of Solaris. Say "SunOS
6590 4" instead of "SunOS" for SunOS 4.
6591 (awk): Mention more of the limitations of traditional Awk.
6592 (cat): Don't talk about cat -v.
6594 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
6596 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
6597 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

6616 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
6617 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
6619 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
6620 (.x.1): Ignore the time stamp in the .TH line when deciding whether
6621 to update the man page. That way, we don't have to check in new

6636 Problem reported by Ralf Menzel.
6638 2005-06-08 Derek Price <derek@ximbiot.com>
6640 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6641 renaming them since they are about to be redefined anyhow.
6643 2005-06-08 Derek Price <derek@ximbiot.com>
6645 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6646 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6647 Move m4_undefine to alphabetical order.
6649 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6651 * README: Recommend GNU M4 1.4.3 or later.
6652 * doc/autoconf.texi (Introduction): Likewise.
6653 Reword to avoid some formatting glitches.
6654 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6655 Clarify explanation of HP compiler bug.
6656 Redo example output tp match current CVS snapshot.
6657 Use @example.org in email addresses when the examples
6658 might get inadvertently cut-and-pasted into user code.
6659 Remove example of autom4te usage that doesn't seem to work now.
6660 Use modern AC_INIT (except when the example is meant to be
6661 shown with Autoconf 2.13).
6662 Update ksh info for Solaris 9 and later.
6664 Modernize description of Automake versions a bit.
6665 Don't claim a future version of Autoconf is near.
6666 * doc/install.texi: Reword to avoid some formatting glitches.
6668 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6670 * doc/autoconf.texi: Add [] to examples, so that the manual
6671 follows its own advice about quoting better.
6672 Reword to avoid some formatting glitches.
6673 * doc/installt.exi: Reword to avoid some formatting glitches.
6675 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6676 Tru64 ksh pattern matching bug. Reported against Libtool by
6677 Albert Chin <libtool@mlists.thewrittenword.com> and
6678 Nicolas Joly <njoly@pasteur.fr>.
6680 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6682 m4_cdr of one-member list was [[]] (one-member list containing an
6683 empty string) instead of [] (an empty list. Callers were skewed to
6684 match this misbehaviour. As a consequence of this:
6685 - m4_foreach([x], [], [foo]) expanded to `foo', while
6686 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6687 This bug has been fixed:
6689 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6690 expand to an empty string; print error msg if called without
6692 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6693 misbehaviour; handle [] and [[]] correctly.
6695 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6697 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
6698 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
6699 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
6701 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6703 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6704 swallow records with more than 99 fields.
6705 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6706 parse the long line.
6708 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6710 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6711 swallow literals longer than 399. Reported by Ralf Wildenhues.
6712 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
6713 to workaround this limitation.
6715 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
6717 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6718 to gfortran, and make these the first two compiler names
6719 checked (following the general autoconf preference for gcc).
6721 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6723 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6724 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6725 (testsuite): Make sure autotest.m4f is up-to-date before using it.
6727 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
6729 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6730 expression of unbounded size when processing the --list
6731 option. This runs afoul of a limit of 399 bytes per regular
6732 expression on AIX. Problem reported by Ralf Wildenhues.
6734 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
6736 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
6737 * doc/autoconf.texi (Particular Headers): Reword example
6738 for multiline stdbool replacement.
6739 (Setting Output Variables): Reword text a bit. Don't
6740 give all the details about |#_!!_#|.
6741 Reword description of line replacement.
6743 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6745 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6746 now contain newlines, and substituted files must be referenced on
6747 a line alone; the sed scripts to substitute them are now very
6749 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6750 commands can be put in a sed script portably.
6751 * doc/autoconf.texi (Setting Output Variables): Document above
6752 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
6753 use of multiline substitution.
6754 * tests/torture.at: No longer expect substitution of newline to fail.
6756 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
6758 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
6759 From Ralf Menzel (trivial change).
6761 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6763 * tests/local.at: Don't attempt to check for negated character
6764 classes in shell scripts. The test was too brittle.
6766 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6768 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6769 * doc/autoconf.texi (Limitations of Builtins): Document this
6772 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6774 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6775 common code; used in many places in the tree.
6776 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
6777 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6779 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
6781 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
6782 messages when ac_unique_file is not found.
6783 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6784 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6785 commands, for consistency with AC_MSG_ERROR and such.
6787 * bin/autoconf.as: Make more use of "shift 2" in option processing.
6789 * bin/Makefile.am: Merge the two rules for creating scripts.
6791 2005-05-23 Stepan Kasal <kasal@ucw.cz>
6793 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
6794 obsolete; it was never documented.
6795 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
6797 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6799 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6800 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6801 (ac_top_builddir): ... this ...
6802 (ac_top_build_prefix): ... to this; the old name is also kept, for
6803 backward compatibility.
6804 (ac_top_builddir_sub): New variable, without the trailing slash,
6806 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6807 * doc/autoconf.texi (Configuration Actions): Rename
6808 ac_top_builddir to ac_top_build_prefix.
6809 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
6810 at_top_builddir to at_top_build_prefix.
6811 * lib/autotest/general.m4 (AT_INIT): Likewise.
6813 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6815 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6818 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6820 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6821 argument to m4_foreach. I guess it was necessary in the past,
6822 but I think it's a no-op now.
6824 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6826 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6827 ``cat <<_ACEOF'' commands to one.
6828 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6829 * lib/autoconf/status.m4: On various places, use expr instead of
6831 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6832 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6833 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6835 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6836 the wrong patterns between ``case'' and ``esac.'' The previous
6837 code had false positives.
6839 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6841 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

6884 2005-05-13 Stepan Kasal <kasal@ucw.cz>
6886 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
6888 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
6889 enough arguments, similarly as in m4_bpatsubsts.
6891 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6893 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
6896 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6898 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6899 for absolute directory names in one loop.
6900 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
6901 abbreviations of --version and --debug.
6903 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6905 * doc/autoconf.texi (Autoconf Language): Be more precise about
6906 quoting rules. Problems noted by Stepan Kasal.
6907 Also, throughout this document, be more careful about white space.
6908 "blank", "white space", and "space" all have different meanings
6909 and we should be careful to say what we mean.
6911 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6913 Fix C++ related problems reported by Werner Lemberg.
6914 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6915 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6916 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6917 avoid problems with C++ and throw.
6918 * tests/compile.at: .cpp, not .cc.
6920 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6922 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6924 * doc/autoconf.texi (Generic Functions): Typos.
6926 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6928 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6929 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6930 set by latest automake.
6932 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6934 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6935 outputs 0 on GNU/Linux these days.
6937 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6939 * doc/autoconf.texi (Autoconf Language): Add more description
6940 about quoting heuristics.
6941 (Limitations of Builtins): Describe "set -" problems.
6943 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6945 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6948 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6949 by AC_DEFINE; it was a mistake.
6950 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6952 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6954 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6956 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6958 * doc/autoconf.texi (External Software): Quadrigraphs are not
6959 processed correctly in AS_HELP_STRING; avoid this in the examples.
6960 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6961 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6962 comment and reduce m4_default([foo], []) to [foo].
6963 (m4_strip): Update the explanation.
6965 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6967 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6968 Remove core.conftest.* too; it's generated by Tru64 5.1.
6969 Problem reported by Jennis Pruett.
6970 * lib/autoconf/functions.m4
6971 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6972 Don't bother to remove core files; AC_RUN_IFELSE should do that
6975 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6977 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6979 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6981 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

6984 2005-04-15 Stepan Kasal <kasal@ucw.cz>
6986 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
6989 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6991 * doc/autoconf.texi (External Software, Package Options): Add
6992 examples showing how to implement --with-* and --enable-* options.
6994 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6996 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6997 as well as configure.in. Problem reported by Gregorio Guidi.
6999 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7001 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7002 pattern for alloca snippet.

7015 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7017 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7019 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7020 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7021 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7022 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7023 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7025 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7027 * NEWS: The configure command now warns you if you attempt to use
7028 a directory whose name contains a special character like space,
7030 * doc/autoconf.texi (Installation Directory Variables): Allow
7031 "," in file names. Do not use \@; it's not a portable regexp.
7032 * bin/Makefile.am (edit): Likewise.
7033 * lib/Makefile.am (edit): Likewise.
7034 * tests/Makefile.am (edit): Likewise.
7035 * tests/semantics.at: Likewise.
7036 * tests/torture.at: Likewise.
7037 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7038 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7039 * doc/autoconf.texi (File System Conventions): Warn about
7040 unportable file names.
7041 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7043 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7044 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7045 ac_pwd, and quote srcdir.
7046 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7048 * doc/autoconf.texi: Fix some systematic formatting problems.
7049 ".)" needs a following @: if not at the end of a sentence, and
7050 similarly for "!)". "etc." should be preceded by a comma.
7051 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7053 2005-03-22 Bruno Haible <bruno@clisp.org>
7055 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7056 argument is often called 'build-aux'.
7058 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7060 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7061 macro AC_TRY_LINK is obsolete.
7062 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7065 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7067 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7068 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7069 from a Common Lisp's `cl'.
7070 (AC_PROG_CXX): Behave according to the documentation: don't
7071 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7072 make the variable CCC precious; use `cl.exe', not `cl'.
7074 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7075 Alexandre Duret-Lutz <adl@gnu.org>
7077 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7078 /dev/null, as "configure" shouldn't read stdin, and this insulates
7079 us from problems (e.g., when testing for "cl"). Also, do this
7080 redirection before invoking "hostname" or "uname", and keep the
7081 original input stream available via...
7082 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7083 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7084 bother with "</dev/null" since it's now done at the top of
7086 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7087 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7088 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7089 * doc/autoconf.texi (File Descriptor Macros): New section.
7090 (Printing Messages): Mention it.
7091 * tests/base.at (Input/Output): New test.
7093 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7095 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7096 newline if neither \c nor -n work, as that would output two
7097 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7099 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7101 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7102 This causes that any required macros inside will get before the if.
7103 * doc/autoconf.texi (autom4te.cache): A typo.
7105 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7107 Undo previous change, except keep the change to
7108 lib/autoconf/programs.m4 that replaced grep with shell
7109 pattern-matching. This is because net-snmp configure reads stdin.
7110 Reported by Noah Misch.
7112 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7114 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7115 from /dev/null, as "configure" shouldn't read stdin, and this
7116 insulates us from problems (e.g., when testing for "cl").
7117 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7118 before invoking "hostname" or "uname".
7119 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7120 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7121 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7122 "</dev/null" since it's now done at the top of 'configure'.
7123 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7124 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7125 Also, replace grep with shell pattern-matching, to save a process.
7127 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7129 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7130 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7131 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7134 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7136 * doc/autoconf.texi (Limitations of Usual Tools): Document that

7150 Mention that shells no longer inherit IFS.
7151 Don't recommend PATH_SEPARATOR=';' so strongly.
7152 Mention that $RANDOM might expand to the empty string.
7153 "symlink" and "soft link" -> "symbolic link".
7154 Improve mktemp description (reported by Bruno Haible).

7230 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7232 Try not to generated lines of unlimited length, as POSIX places a
7233 2047-byte limit on line length of portable text files.
7234 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7235 Use newline as a separator, not space.

7270 Modified from a suggestion by Stepan Kasal.
7272 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

7293 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7294 Update the long comment explaining it.
7296 m4_require no longer writes an ``is required by'' line to the
7297 execution stack. It contains only one bit of non-redundant
7298 information: that the macro was required, not called. And even
7299 this bit is useless in most situations: have you ever met a macro
7300 which both calls and requires the same macro?
7302 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7303 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7310 (_m4_require_call): Use it.
7311 * tests/m4sugar.at (m4_require): Expect output without the
7312 ``is required by'' messages.
7314 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

7348 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
7350 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7351 Warn about newline stripping in `` and $(). Update Solaris
7353 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7354 X insulates us from future changes to Posix.
7355 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7358 2005-01-19 Stepan Kasal <kasal@ucw.cz>
7360 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

7380 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7382 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
7383 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update

7404 (_m4_divert_n_stack): New macro; the expansion is
7405 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
7407 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
7408 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7409 stored in _m4_divert_diversion or _m4_divert_dump.
7410 (m4_divert_pop): When the parameter is given, compare the symbolic
7411 name with the last diversion pushed on the stack. Previously, the
7412 current diversion was compared with the numeric value of the
7413 diversion given as the parameter.
7414 (m4_require): If the macro hasn't been expanded yet, call ...
7415 (_m4_require_call): this new macro.

7448 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

7720 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
7722 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7723 "char c = '\200';" rather than "char c = 0x80;" as the

7725 overflow on signed char hosts.
7727 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
7728 to -qlanglvl=ansi. We don't want to disable extensions.

7841 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7842 "/usr/include", clear ac_x_includes instead of leaving it as "no"

7888 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7889 doc/fdl.texi, doc/standards.texi: Sync with master copy.

7910 This isn't a complete fix but it's an improvement.
7912 * bin/autoconf.as (autom4te_options): New var.
7913 Use it instead of appending to AUTOM4TE, so that we can allow
7914 spaces in the build directory's absolute name.
7915 * bin/autoheader.in ($autoconf): Allow spaces in file names.

7947 * lib/autom4te.in (Automake-preselections): Preselect
7948 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7950 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7952 * lib/autom4te.in (Automake-preselections): Preselect
7953 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

7966 with pdksh, too. Problem reported by Patrick Welche via
7968 * doc/autoconf.texi (Shellology): Note that set -o posix is
7969 useful for pkdsh, too.
7971 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7973 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7974 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7975 Don't fail if ENV or BASH_ENV is readonly.

7988 names like "aux". Problem reported by Eric Blake.
7990 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7991 by zero instead of array size, so that we can use any arithmetic
7992 constant expression (instead of requiring an integer constant
7993 expression). This allows us to test expressions like DBL_MAX <
7994 LDBL_MAX, which didn't conform to the C standard using the old
7996 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7997 now that we can do floating-point tests at compile time.
7999 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8001 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8002 and LDBL_EPSILON, as the resulting expression isn't an
8003 integer constant expression and violates the C standard.
8004 Problem reported by Nelson H. F. Beebe. Also, check
8005 for "L" suffix, and check that long double doesn't have
8006 worse range or precision than double, that mixed-mode
8007 arithmetic doesn't generate a diagnostic, that double
8008 constants fit in long double.

8037 change). Patch reported by Ralf Wildenhues in
8038 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8040 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8041 function F exists if the compiler and linker let you compile an
8042 expression like (F != 0). Recent versions of GCC optimize away
8043 the reference to F in that case, since every function address must
8044 be nonzero, so the link succeeds even if F does not exist.
8045 Problem reported by Manu in
8046 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8048 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8049 "Unix". Many uses changed.
8050 (Limitations of Builtins): Explain better why the ! command isn't
8053 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8055 * lib/autom4te.in (Automake-preselections): Preselect
8056 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8058 2004-05-19 Kevin Ryde <user42@zip.com.au>
8060 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8061 referencing AC_FUNC_STRERROR_R.
8063 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8064 note pessimistic assumption when cross compiling.
8066 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8068 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8069 (until 2004) invoked subcommands with sh -e, contra POSIX.
8070 Reported by Kevin Ryde.
8072 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8074 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8075 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8076 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8077 `test -f " /usr/bin/grep"', which _always_ failed.
8078 (AC_PROG_SED): Ditto bogus PATH fix.
8079 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8080 requires that grep correctly supports _multiple_ `-e' options, rather
8081 than stating only that grep should accept `-e'.
8083 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8085 Port to C99, which requires that 'exit' be declared.
8087 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8088 to ensure that stdlib.h is included.
8089 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8090 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8091 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8092 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8093 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8094 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8095 when using 'exit' in a test; C99 requires that 'exit' be declared.
8097 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8099 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8100 now prefers 'grep' implementations that accept -e.
8101 (Limitations of Usual Tools): Describe problems of traditional
8102 egrep and fgrep with long input lines, and of traditional grep
8104 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8105 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8106 All callers changed. Append /usr/xpg4/bin to the PATH, for
8108 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8109 the user with complaints about multiple -e options.
8110 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8111 Define it with AC_PROG_GREP.
8112 * configure.ac (AC_PROG_GREP): Add.
8113 * lib/freeze.mk (GREP): New macro.
8115 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8117 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8118 a possible candidate only after all others fail, rather than
8119 consulting it first. This improves backward compatibility by
8120 better reflecting the way shell selection occurred in previous
8121 versions of Autoconf, and should help to avoid triggering latent
8122 problems in other packages, such as the one in Automake where zsh
8123 is not handled robustly:
8124 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8125 Although it is not Autoconf's responsibility to work around
8126 problems in Automake, it nevertheless makes sense to avoid
8127 introducing unnecessary incompatibilites.
8129 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8130 Gary V. Vaughan <gary@gnu.org>
8132 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8133 how deeply nested we are when a suitable tool is found, set the
8134 ac_path_TOOL_found flag.
8135 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8136 nested we are in this macro. Break out of all 3 nested loops if
8137 ac_path_TOOL_found is set.
8139 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8141 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8142 of the _AS_PATH_WALK loop too if GNU flavor is found.
8144 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8146 * doc/autoconf.texi (Limitations of Make): Update documentation
8147 for `$<'. New entry `Long lines', based on a report from Simon
8148 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8149 paragraph about DJGPP, based on a mail from Richard Dawe.
8151 2004-04-20 Paul Eggert <eggert@twinsun.com>
8153 * tests/c.at (C keywords): Don't assume that GCC supports
8154 "restrict" and "inline", as sufficiently-old GCC versions do not
8155 (also, GCC configured to be in pedantic C89 mode does not).
8156 Problem reported by Sumit Pandya in:
8157 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8159 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8160 consider -g to work if it generates warnings when plain compiles
8161 don't. Problem reported by Braden McDaniel in:
8162 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8164 * doc/autoconf.texi (Slashes): New section, to document a problem
8165 reported by Jim Meyering in:
8166 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8168 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8169 linker output files before linking, to work around IRIX 6 linker bug.
8170 Problem reported by Rainer Orth in:
8171 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8173 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8175 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8176 best tool so far counter rely on the tool path variable name to
8177 avoid checks for one tool being affected by the results of running
8178 the length check on a previous tool.
8180 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8181 match expression argument, as different greps have different
8182 regular expression flavours.
8183 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8185 (AC_PROG_EGREP): Pass 'EGREP$'.
8186 (AC_PROG_GREP): Pass 'GREP$'.
8188 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8190 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8191 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8193 2004-03-29 Paul Eggert <eggert@twinsun.com>
8195 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8196 Types, Specific Compiler Characteristics, System Services,
8197 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8198 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8199 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8200 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8202 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

8211 2004-03-28 Paul Eggert <eggert@twinsun.com>
8213 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8214 now defines HAVE_DECL_TZNAME if it is declared, when
8215 HAVE_STRUCT_TM_TM_ZONE is not defined.
8216 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8217 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
8223 superfluous backslashing of quotes (") in sed expressions;
8224 thanks to Paul Eggert.
8226 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8228 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8229 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8230 H. F. Beebe for the bug report.
8232 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8234 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8235 quoted -cmdline argument in Portland Group compiler (bug
8236 reported by Jeffrey J. Barteet).
8238 2004-03-25 Kevin Ryde <user42@zip.com.au>
8240 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

8265 * tests/mktests.sh: Do not generate tests for the
8267 * NEWS: Document these changes.
8269 * doc/autoconf.texi: Avoid macros with unbraced arguments,
8270 they make TeX hang up.

8280 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
8281 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
8284 2004-03-03 Paul Eggert <eggert@twinsun.com>
8286 * bin/Makefile.am (edit): Don't use $< in a context where
8287 POSIX doesn't require support for it. Use $@.in instead.
8288 Problem reported by Anthony N. Frasso in
8289 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
8290 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
8292 2004-02-23 Gary V. Vaughan <gary@gnu.org>
8294 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
8295 from the next generation of Libtool.
8296 * lib/autom4te.in (Autoreconf-preselections): Ditto.
8298 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8300 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8301 is not always thread-safe. Report from Nathanael Nerode.
8303 2004-02-18 Paul Eggert <eggert@twinsun.com>
8305 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8306 problem on QNX reported by Stephen Rasku in
8307 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
8309 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
8310 $(m4sh_m4f_dependencies); this removes a FIXME.
8311 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
8312 (MAINTAINERCLEANFILES): Split into pieces,
8313 one per related section. Add $(srcdir)/wrapper.in.
8315 2004-02-09 Paul Eggert <eggert@twinsun.com>
8317 * doc/autoconf.texi (Setting Output Variables): Emphasize that
8318 AC_SUBST provides no portable way to escape literal newlines.
8320 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8321 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8322 Darwin uses -lcrt2.o and there's little point to cataloging all
8323 the system variants. Partial fix reported by Andreas Waechter in:
8324 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
8325 for bug reported by Nelson H. F. Beebe in:

8338 refer to the correct file.
8339 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
8340 the behavior of the third argument.
8341 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
8342 correctly the behavior of the third argument. Document
8343 what the three macros that AU_DEFUN defines do. Fix
8344 warning message when the third argument includes $0
8345 (reported by Alexandre Duret-Lutz).

8348 Eric Sunshine <sunshine@sunshineco.com>
8349 Paul Eggert <eggert@twinsun.com>
8351 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

8368 use AS_INIT_WITH_SHELL_FN.
8369 * bin/autoconf.in, tests/wrapper.in: Regenerated.
8371 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

8397 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
8399 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8400 2003 (except 1997) to the list of copyright years. This undoes
8401 the 2003-05-22 change, which removed the older years from the list.
8402 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8408 grep or ggrep program in PATH that accepts as long lines as
8410 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
8412 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
8413 egrep and fgrep respectively if $GREP -E/-F don't work.
8414 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
8415 _AC_PROG_GREP, and AC_PROG_SED.

8446 2004-01-26 Paul Eggert <eggert@twinsun.com>
8448 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8449 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8450 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8451 not <inttypes.h>. Problem reported by Tim Mooney in
8452 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8453 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8456 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8457 otherwise "make check" fails because it forbids cmp (I guess
8458 because cmp treats files as binary on DOS-like systems).
8460 * tests/mktests.sh: Update copyright date to 2004, since some tests
8461 have changed in 2004.
8463 2004-01-23 Gary V. Vaughan <gary@gnu.org>
8465 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
8466 non-truncating sed or gsed program in PATH.
8467 * tests/acprograms.at: Add it.
8468 * doc/autoconf.texi (Particular Programs): Document it.
8471 2004-01-15 Paul Eggert <eggert@twinsun.com>
8473 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8474 -std1 disables some useful extensions on Tru64. Problem reported
8476 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
8478 2004-01-14 Paul Eggert <eggert@twinsun.com>
8480 * doc/autoconf.texi (Programming in M4sh): Document that
8481 AS_MKDIR_P succeeds if the destination is a symbolic link
8482 to an existing directory.

8505 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8506 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8507 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8508 AC_COMPILE_IFELSE, since we now assume our caller invokes
8509 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.

8511 of AC_RUN_IFELSE; this avoids the warning mentioned above.

8993 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8994 directory for AC_CONFIG_COMMANDS' first argument exists.
8995 This makes valid the invocation of _AC_SRCPATH that follows.
8996 Reported by Eric Sunshine.
8997 * doc/autoconf.texi (Configuration Commands): Adjust.
8999 2003-09-26 Akim Demaille <akim@epita.fr>
9001 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9002 Reported by Ralf Corsepius.
9004 2003-09-26 Akim Demaille <akim@epita.fr>
9006 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the

9011 2003-09-26 Paul Eggert <eggert@twinsun.com>
9013 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

9020 The test suite are sometimes assigning timings incorrectly.
9021 Reported by Henk Krus.
9022 Diagnosed by Nicolas Joly.
9024 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9026 Instead of making AT_help a sequence of assignments to grow
9027 $at_help_all, just make AT_help_all be the growing contents of
9028 $at_help_all, and make a single assignment in...

9040 * bin/Makefile.am (edit): Handle '@configure_input@'.
9041 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9042 (ifnames): chmod -w.
9043 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9044 executables, not bin/ executables! Otherwise all the magic needed
9045 to find non installed files is turned off. This caused a failure
9046 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9047 as found in its environment (sent by tests/autoreconf): pointing
9048 to bin/autom4te that could not find its files.
9049 * tests/mktests.sh: Force the replacement of generated files, for
9050 the sake of "mv" program that are interactive when overwriting a

9145 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9147 Add support for newer Fortran dialects. The F77 interface is
9148 unchanged, and continues to support Fortran 77. New FC macros
9149 correspond to all the old F77 macros, with output variables FC,
9150 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9151 available dialect, but older dialects can be specified. There are
9152 new macros AC_FC_SRCEXT to set the source extension, and
9153 AC_FC_FREEFORM to accept free-form source files.

9275 ($help): Use Autom4te::ChannelDefs::usage.
9276 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9277 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9279 2003-08-21 Akim Demaille <akim@epita.fr>
9281 First stab at preserving warnings between calls to autom4te,
9282 including when the cache is used.
9284 There are still several issues: (i) there are too many runs of m4
9285 (one for include, one for warnings, and some more), (ii) warnings
9286 spreading on several lines are not handled gracefully, (iii) the
9287 code meant to have the call stack display for errors does not work
9288 (its handling should move from m4 to autom4te).
9290 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9292 (@preselect): Add m4_warn.
9293 ($exit_status): Remove, use $exit_code.
9294 ($help): Use Autom4te::ChannelDefs::usage.
9295 (&handle_m4): No longer define the m4_warnings.
9296 At each run, extract and report the warnings.
9297 Always cache the result, including if the exit status is on
9298 failure, since if nothing changes, we should result in the same
9299 failure, hence we can use the cache.
9300 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9301 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9303 (m4_warn): Redefine as a do-nothing: it is its invocation that
9304 matters, as warnings are now reported via traces.
9305 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9306 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9307 the latter reveals calls to the former.
9311 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9313 2003-08-21 Akim Demaille <akim@epita.fr>
9315 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9337 2003-08-20 Akim Demaille <akim@epita.fr>
9339 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9340 Reported by Alexandre Duret-Lutz.

9344 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9345 * bin/autom4te: Adjust.
9346 In particular, be Autoconf tools are really silent when properly
9347 working, bind the verbosity of the 'note' channel to $verbose.
9348 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9349 (&xsystem, &contents): Remove, since they are exported by...

9411 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9412 shorter column three. Add DESCRIPTION to log file content.
9414 2003-08-13 Derek Price <derek@ximbiot.com>
9416 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

9472 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9473 not all of them. This fixes 1. the fact that when testing
9474 Autoconf there are many many config.log, 2. the incorrect use of
9475 top_srcdir to find config.log.
9476 Don't mix the detailed output of failed test with the summary of
9477 failures. Rather, append detailed log afterwards.

9502 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
9503 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
9504 ensuring we add -std1 for full-ANSI.
9506 * doc/autoconf.texi (hdrindex): New macro.

9564 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9566 * lib/Autom4te/General.pm (END): Rewrite exit code processing.

9570 63 for version mismatches.
9572 2003-05-23 Akim Demaille <akim@epita.fr>
9574 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9575 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9576 the middle of a line).
9577 * lib/m4sugar/m4sugar.m4: Likewise.
9578 Remove useless spaces in comments.
9580 2003-05-23 Akim Demaille <akim@epita.fr>
9582 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
9583 exit 63, so that we (or Automake's "missing") can tell the
9584 difference with a plain failure.

9594 Paul Eggert <eggert@twinsun.com>
9596 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9597 Remove `#include <stdlib.h>' from the list; we should never
9598 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9599 resulting namespace pollution would cause other tests to fail.
9600 Configure scripts run with some older versions of g++ and HP's
9601 aCC would fail due to such an #include. Problems reported by
9602 Matthew Mueller in <http://bugs.debian.org/120704> and by
9604 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9605 In the test, use the test declaration before including <stdlib.h>,
9606 as that's closer to how it'll be used.
9608 2003-05-23 Akim Demaille <akim@epita.fr>
9610 * doc/autoconf.texi (Header Portability): ucred.h.
9613 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9615 Overhaul Autotest's logging: generate separate log files
9616 in testsuite.dir/NNN/testsuite.log, and append them to
9617 testsuite.log instead of re-running the test verbosely.
9619 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9620 file descriptor, write 0 to at_status_file instead of setting
9621 at_status=0, initialize some new variables (at_status_file,
9622 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9623 to rerun the tests, instead append the at_group_log to the
9624 at_suite_log when a test fails.
9625 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9626 with the AS_MESSAGE_LOG_FD redirected to stdout.
9627 (AT_CLEANUP): save the output status in $at_status_file
9628 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9630 (AT_CHECK): since tests are run with a redirected stdout,
9631 and used to be re-run in verbose mode, turn some $at_verbose
9632 into echo, and don't redirect the output of testing stdout
9635 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9636 the name of the debugging directory and information about

9756 2003-05-06 Akim Demaille <akim@epita.fr>
9758 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9759 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9760 by aclocal.m4 is changed it might require the importing of another
9761 m4 extension file, i.e., aclocal must be run.
9763 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9764 (&parse_args): Use --force with aclocal if required and supported.
9765 (&autoreconf_current_directory): Use &run_aclocal.

9772 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9773 argument instead of a file name, so that the request file remains
9774 open during the whole autom4te run.

9776 (&freeze): Lock the $icache_file.
9778 2003-04-29 Derek Price <derek@ximbiot.com>
9780 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9781 seperator with m4_append_uniq(). It doesn't work.
9782 (AT_CLEANUP): Add `;' to end of at_help_all.
9783 (AT_INIT): Allow --keywords to be specified more than once. When
9784 grepping $at_help_all for keywords, use the field and keyword
9785 seperators to ensure a complete keyword match. Alter at_prev handling
9786 to support the new --keywords behavior.

9792 entries on one line, for brevity and to make it easier for me to
9793 sort my dir-example file in the Texinfo distribution :).

10008 $ac_prefix_program.
10011 2002-12-23 Paul Eggert <eggert@twinsun.com>
10013 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10014 innocuous variant befor including <limits.h> or <assert.h>. This
10015 works around a bug reported by Albert Chin: HP-UX 11i
10016 (and earlier versions) have a <limits.h> that declares
10017 gettimeofday and many other functions.
10019 2002-12-03 Paul Eggert <eggert@twinsun.com>
10023 * NEWS, configure.ac: Update version.
10025 * doc/fdl.texi: Upgrade to FDL version 1.2.
10027 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10028 nontrivially in main's body, so that f's external declaration is
10029 not optimized away in AIX. This should fix the bug reported by
10031 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10033 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10034 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10035 defined, to support freestanding compilers. This should fix the
10036 bug reported by Momchil Velkov in
10037 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10039 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10040 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10041 obsolete AC_CHECK_TYPE. The missing empty arg was reported

10052 \(.*\) match is too long and there is something more to be checked.

10071 Update from masters.
10073 2002-11-14 Akim Demaille <akim@epita.fr>
10075 * Makefile.maint: Sync with Bison, i.e.:
10076 (po-check): Scan .l and .y files instead of the
10077 .c and the .h files that they generate. This fixes the bug
10078 reported by Tim Van Holder in:
10079 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10080 Look for N_ as well as for _. Try to avoid matching #define for
10084 2002-11-14 Akim Demaille <akim@epita.fr>

10096 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10097 than assigning in main, to avoid HP cc +O3 optimizing it away.
10099 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10101 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10102 option. Process --recheck after parsing all options. Pass -q
10103 option to configure on --recheck.
10104 (AC_OUTPUT): Pass -q from configure to config.status.
10105 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10106 arguments to record.
10107 * doc/autoconf.texi (config.status Invocation): Document
10108 config.status -q option.
10110 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10112 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10113 Makefile.in if Makefile.am exists.
10114 (output): Strip `.am' from Makefiles. Don't
10115 output AC_CONFIG_FILES if no Makefiles were found.

10135 Reported by Ezra Peisach.
10137 2002-11-05 Akim Demaille <akim@epita.fr>
10139 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10141 We _have_ to stop using the old compatibility scheme that tried to
10142 avoid useless backslashes because Libtool 1.4.3 contains a
10143 AC_DEFINE([error_t], [int],
10144 [Define to a type to use for \`error_t' if it is not
10145 otherwise available.])
10146 We _have_ to quote the single quote and backslashes with \. The
10147 old compatibility scheme saw that ` was backslashed, and therefore
10148 did not quote the single quote. Hence before this patch, Autoconf
10149 was not compatible with Libtool.
10151 2002-11-04 Paul Eggert <eggert@twinsun.com>
10153 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10194 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10195 Make variable, not a shell variable.
10196 Suggested by Bruno Haible.
10198 2002-10-31 Akim Demaille <akim@epita.fr>
10200 * bin/autom4te.in (load_configuration): Reject #args out of any

10223 Problem reported by Bruno Haible.

10227 * doc/autoconf.texi (Header Templates): Put also in words what the

10229 (Customizing autom4te): s/--cache=/--cache /.
10231 2002-10-29 Akim Demaille <akim@epita.fr>

10510 (AT_CHECK_M4SUGAR): Use it.
10511 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10513 * tests/tools.at (autom4te): Now it does exit 1.
10515 2002-10-17 Akim Demaille <akim@epita.fr>
10517 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
10518 Fixes the `AC_ARG_VAR' test failures.
10519 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
10520 * lib/freeze.mk (check-forbidden-patterns): New.
10521 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
10522 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
10523 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
10525 Reported months ago by H. Merijn Brand.
10527 2002-10-17 Akim Demaille <akim@epita.fr>
10529 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
10531 2002-10-16 Paul Eggert <eggert@twinsun.com>
10533 * Makefile.maint (wget_files): Remove ansi2knr.c.
10534 (ansi2knr.c-url_prefix): Remove.
10536 2002-10-16 Akim Demaille <akim@epita.fr>
10538 Because of caching, some files that no longer exist and are no
10539 longer required can still cause errors.
10540 Reported by Alexandre Duret-Lutz.
10542 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
10543 to frozen files in @ARGV, as @ARGV must remain being a list of
10544 files. Rather, at M4 call sites, use this...
10545 (&files_to_options): New function.
10546 (&freeze): Use &error.
10547 (&up_to_date): If a file that was included according to the cache
10548 is no longer there, then the output is out dated.
10549 (&main): Don't even check whether a file is up to date is anyway
10551 * tests/tools.at (autom4te cache): New.
10553 2002-10-16 Akim Demaille <akim@epita.fr>
10555 * bin/autoconf.as: Kill dead options.
10556 * bin/autoupdate.in (&parse_args): Kill old options.
10557 * bin/autoreconf.in (&parse_args): Remove dead options.
10559 (&autoreconf): Report the directories we enter *and leave*, so
10560 that error messages can be easily located, and use GNU Make
10561 format, so that Emacs' compile mode understands us.
10562 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
10563 if some file was changed instead of `print'.
10564 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
10565 (&parse_args): Remove the dead options.
10566 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
10567 autoheader's quiet mode.
10568 (AT_CHECK_AUTOUPDATE): Likewise.
10569 * tests/tools.at (autoupdate): Adjust.
10570 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10572 2002-10-11 Akim Demaille <akim@epita.fr>
10574 No longer use CPP to check for the existing of headers: use CC to
10575 check for compilability.
10577 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
10578 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
10579 (_AC_CHECK_HEADER_NEW): Rename as...
10580 (AC_CHECK_HEADER): this.
10582 * lib/autotest/general.m4 (AT_INIT): Include the failed test
10583 numbers in the Subject suggestion.
10585 2002-10-11 Akim Demaille <akim@epita.fr>
10587 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
10588 Suggest using AC_CHECK_DECLS instead.
10590 2002-10-11 Akim Demaille <akim@epita.fr>
10592 * tests/torture.at (AC_ARG_VAR): Have configure report the value
10595 2002-10-11 Akim Demaille <akim@epita.fr>
10597 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
10598 file name to enable parallel executions.
10599 From Sam Varshavchik.
10601 2002-10-08 Akim Demaille <akim@epita.fr>
10603 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10604 aclocal invocation, as Gettext macros might not be visible to
10606 Instead of blindly running autopoint, scan configure.ac (not the
10607 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10608 Reported by Paul D. Smith.
10610 2002-10-08 Paul Eggert <eggert@twinsun.com>
10612 Work around problems found when POSIXLY_CORRECT=1 is set.
10613 None of this seems to have anything to do with POSIX, really,
10614 but it's how Perl getopt works.
10615 * bin/autom4te.in (parse_args): Configure GetOpt with
10617 * doc/autoconf.texi (Invoking autom4te):
10618 --warning -> --warnings.
10619 * lib/autom4te.in: --warning -> --warnings.
10621 2002-09-28 Akim Demaille <akim@epita.fr>
10623 * doc/autoconf.texi (autom4te.cache): New section.
10625 2002-09-28 Akim Demaille <akim@epita.fr>
10627 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
10628 (Automake-preselections): Update.
10629 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
10631 2002-09-28 Akim Demaille <akim@epita.fr>
10633 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
10634 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
10635 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10636 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
10638 2002-09-28 Akim Demaille <akim@epita.fr>
10640 * tests/torture.at (Configuring subdirectories): Be robust to
10641 users who use config.site to require for a cache: in this case,
10642 the two last configure runs, using two different sets of
10643 arguments, trigger a legitimate error.
10645 2002-09-28 Akim Demaille <akim@epita.fr>
10647 * tests/m4sh.at (Functions Support, Functions and return Support):
10650 2002-09-28 Akim Demaille <akim@epita.fr>
10652 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
10653 autoheader are Perl programs.
10654 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
10655 (autom4te): Specify that the sources are in the $srcdir.
10656 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10658 2002-09-28 Akim Demaille <akim@epita.fr>

10661 (tm_zone): Move their rules to...
10662 * lib/autoconf/types.m4: here, using AN_ macros.
10663 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10664 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
10665 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
10666 * lib/autoconf/programs.m4: here.

10668 (ETAGS_FOR_AUTOCONF): New.
10671 2002-09-28 Akim Demaille <akim@epita.fr>

10675 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
10676 that were listed in the original autoscan.list.
10677 * lib/autoconf/headers.m4: Similarly with headers.
10678 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10679 (.m4.m4f): Don't pass --prepend-include, since that's done by
10680 tests/autom4te itself.
10681 * lib/autoscan/Makefile.am: Include freeze.mk.
10682 (autoscan.list): New target --this file is no longer a source.
10683 (autoscan.pre): New file.
10685 2002-09-28 Akim Demaille <akim@epita.fr>
10687 * bin/autoscan.in (@kinds): Make them singular.
10689 (&init_tables): When --debug, report the list of rules to ease
10690 tracking changes in autoscan.list.
10691 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10693 2002-09-28 Akim Demaille <akim@epita.fr>
10695 * lib/autoscan/functions, lib/autoscan/headers,
10696 * lib/autoscan/identifiers, lib/autoscan/makevars,
10697 * lib/autoscan/programs: Merge into...
10698 * lib/autoscan/autoscan.list: this.
10699 * bin/autoscan.in (&init_tables): Adjust.
10701 2002-09-28 Akim Demaille <akim@epita.fr>
10703 * lib/autoscan/functions, lib/autoscan/headers,
10704 * lib/autoscan/identifiers, lib/autoscan/makevars,
10705 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10706 `functions' line is now prefixed with `function:'.
10707 * bin/autoscan.in (&init_tables): Adjust.
10709 2002-09-28 Akim Demaille <akim@epita.fr>
10711 From now on, autoscan files must always map a macro name to a
10712 word: there is no `default' macro for autoscan.
10714 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10716 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10719 2002-09-28 Akim Demaille <akim@epita.fr>
10721 * bin/autoscan.in (%c_keywords): Remove.
10722 (&used): Keep only track of the words we might be interested in.
10723 (&output_kind): It is no longer needed to look for non active
10726 2002-09-27 Akim Demaille <akim@epita.fr>
10728 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
10729 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
10730 * lib/autoscan/functions: Adjust.
10731 * doc/autoconf.texi (Particular Functions): Adjust.
10733 2002-09-27 Akim Demaille <akim@epita.fr>
10735 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
10737 Thanks to Bill Moseley and Paul Eggert.
10738 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10739 the tmpdir must be created.
10740 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
10741 dir be in the build tree, instead of $TMPDIR.
10743 2002-09-27 Akim Demaille <akim@epita.fr>
10745 * bin/autoscan.in: Improve the comments.
10746 (&parse_args): Drop obsolete undocumented options.
10747 (&output_kind): Output warnings.
10748 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
10749 (getwd): Trigger a warning.
10751 2002-09-26 Akim Demaille <akim@epita.fr>
10753 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10754 Reported by Ralf Corsepius.
10755 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10757 2002-09-26 Akim Demaille <akim@epita.fr>
10759 Single suffix rules and seperated dependencies are not portable.
10761 * doc/autoconf.texi (Installation Directory Variables): Update.
10762 (Limitations of Make): Some about `Single Suffix Rules and
10763 Separated Dependencies'.
10764 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10765 (ifnames, autoscan, autom4te): Un-factor into several rules.
10767 2002-09-25 Paul Eggert <eggert@twinsun.com>
10769 * BUGS (Interoperability bugs): New section. Mention libtool
10770 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10772 2002-09-24 Paul Eggert <eggert@twinsun.com>
10774 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10775 make handles suffix-rules differently from GNU make.
10777 * bin/Makefile.am (SUFFIXES, .in): Remove.
10778 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10779 Move the body of the old .in rule here.
10781 2002-09-16 Akim Demaille <akim@epita.fr>
10783 i960 compilers create `b.out' files by default.
10784 Reported by Ralf Corsepius.
10786 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10787 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10789 2002-09-13 Paul Eggert <eggert@twinsun.com>
10791 * doc/autoconf.texi (Particular Headers): Remove obsolete
10792 reference to `struct timezone' in the description of
10795 2002-09-13 Akim Demaille <akim@epita.fr>
10799 * config/config.sub, config/config.guess: Update.
10800 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10801 * Makefile.am: Adjust.
10803 2002-09-13 Akim Demaille <akim@epita.fr>
10805 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10806 reading config.log when the compiler is rejected.
10807 Suggested by Guido Draheim.
10809 2002-09-13 Akim Demaille <akim@epita.fr>
10811 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10812 (chdir_init) might hang when stat'ing mounted directories.
10813 Reported by Vance Shipley.
10815 2002-09-12 Akim Demaille <akim@epita.fr>
10817 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10820 2002-09-12 Akim Demaille <akim@epita.fr>
10822 * doc/autoconf.texi (Defining Symbols): Present two different
10823 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10824 difference between 1 argument calls, and 2-3 argument calls.
10826 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10828 * doc/autoconf.texi: Review grammar and punctuation.
10830 2002-09-11 Paul Eggert <eggert@twinsun.com>
10832 * doc/autoconf.texi: Fix minor formatting, spelling, and
10834 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10835 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10838 2002-09-11 Akim Demaille <akim@epita.fr>
10840 * doc/autoconf.texi (Questions): Rename as...
10842 (Defining Directories): New.
10844 2002-09-09 Akim Demaille <akim@epita.fr>
10846 * doc/autoconf.texi (Making testsuite Scripts): Update.
10847 Suggested by Nishio Futoshi.
10849 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10851 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10852 plain `@' is wanted.
10854 2002-09-09 Akim Demaille <akim@epita.fr>
10856 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10857 `duplicates', since the algorithm was too naive and could keep
10858 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10859 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10860 Reported by Ralf Corsepius.
10861 * tests/torture.at (Configuring subdirectories): Exercise these
10864 2002-09-09 Akim Demaille <akim@epita.fr>
10866 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10867 looking for a replacement file.
10868 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10869 directory is relative.
10870 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10871 directory definition.
10872 Reported by Andreas Schwab and Jim Meyering.
10874 2002-09-06 Akim Demaille <akim@epita.fr>
10876 * doc/autoconf.texi (Setting Output Variables): Clarify what
10877 precious variables are.
10878 Suggested by Pontus Skoeld.
10880 2002-09-05 Akim Demaille <akim@epita.fr>
10882 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10883 (ifnames, autoscan, autom4te): Since we don't only depend on
10884 configure.ac variables (such as VERSION etc.), but also on prefix
10885 and so forth, depend on Makefile, not configure.ac.
10886 Reported by Alexandre Duret-Lutz.
10887 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10889 2002-09-05 Kevin Ryde <user42@zip.com.au>
10891 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10892 doesn't seem to be confined to ia64, just say "some versions".
10894 2002-09-04 Akim Demaille <akim@epita.fr>
10896 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10898 * Makefile.am (maintainer-clean-local): Remove.
10899 (MAINTAINERCLEANFILES): Remove COPYING.
10901 2002-09-03 Paul Eggert <eggert@twinsun.com>
10903 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10904 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10907 2002-09-03 Akim Demaille <akim@epita.fr>
10909 * configure.ac: Bump to 2.53d.
10910 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10911 as of today, on Automake's team suggestion.
10913 2002-09-03 Akim Demaille <akim@epita.fr>
10917 2002-09-02 Akim Demaille <akim@epita.fr>
10919 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10921 * configure.ac: Disable SITE_MACRO_DIR.
10923 2002-09-02 Jim Meyering <meyering@lucent.com>
10925 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10926 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10927 Also, tweak grammar: s/make sure to/be sure to/.
10929 2002-09-02 Paul Eggert <eggert@twinsun.com>
10931 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10932 directory names are generally preferable to physical names.
10934 2002-09-02 Akim Demaille <akim@epita.fr>
10936 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10937 Reported by Raja R. Harinath.
10938 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10939 * bin/autoupdate.in: Use error instead of die.
10941 2002-09-01 Paul Eggert <eggert@twinsun.com>
10943 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10944 ordinary shell concatenation rather than echo+tr+sed command that
10945 runs afoul of a long-line-related sed bug in Solaris 8.
10947 * bin/autoheader.in (parse_args): --warning -> --warnings.
10949 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10950 stdout, as traditional "ls" does.
10951 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10952 _AC_COMPILER_EXEEXT_O): Likewise.
10953 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10955 * bin/autoconf.as: Add --prepend-include option. This patch was
10956 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10957 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10959 * bin/autoconf.in, configure: Regenerate.
10961 * doc/autoconf.texi (Special Shell Variables): Mention
10962 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10964 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10965 MAILPATH and set PS1, PS2, PS4 to default values, to work
10966 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10967 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10968 the Autoconf documentation specifies; fall back to "unset" only if
10969 this fails. Use a shell for-loop for this rather than an m4 loop,
10970 to shorten the output script.
10972 2002-08-30 Paul Eggert <eggert@twinsun.com>
10974 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10975 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10976 for the CDPATH problem. Document PWD.
10977 (Limitations of Builtins): Document the problem that "cd $foo" and
10978 "ls $foo" may refer to different directories in shells conforming
10979 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10980 example, since the old example is now out of date.
10982 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10983 FOO" and "ls FOO" talk about different directories; this catches
10984 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10987 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10988 of rolling our own unset.
10989 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10990 in practice we needn't worry about CDPATH if unset doesn't work.

11016 * lib/Autom4te/General.pm (&xqx): New.
11017 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11018 hand, which is not portable.

11027 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the

11345 This improves on an earlier suggestion by H. Peter Anvin.
11347 2002-05-16 Paul Eggert <eggert@twinsun.com>
11349 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11350 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11351 Both macros now accept an optional source-dir arg.
11352 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11354 * NEWS: Document this.
11355 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11357 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11358 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11359 not for GNU extensions; this undoes part of the 2000-11-03 change,
11360 reverting to 2.13-compatible behavior.
11361 Add new optional argument DIR.
11362 (AC_FUNC_FNMATCH_GNU): New macro.
11364 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11366 2002-05-08 Paul Eggert <eggert@twinsun.com>
11368 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11369 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11370 and it causes a 'test' syntax error if it fails.
11371 Bug reported by Stephen Gildea.
11373 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11374 If prototypes are supported, use them to check this at compile-time,
11375 instead of trying to check it at run-time. If we must do a run-time
11376 check, assume that setvbuf is standard when cross-compiling, as
11377 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11378 Bug reported by Paul D. Smith.
11380 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11381 argument specifying location of getloadavg.c. This removes a
11382 FIXME. This idea was taken from Jim Meyering's implementation in
11384 * doc/autoconf.texi (Particular Functions): Document this.
11385 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11386 that's what the code does; this fixes a bug reported by
11389 2002-05-03 Akim Demaille <akim@epita.fr>
11391 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11392 autopoint instead of gettextize.
11393 ($uses_alocal): Rename as...
11394 ($uses_aclocal): this.
11395 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11396 Suggested by Bruno Haible.
11398 2002-05-03 Akim Demaille <akim@epita.fr>
11400 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11402 2002-04-29 Paul Eggert <eggert@twinsun.com>
11404 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11405 files to be 1 second older; just set them to be the same time.
11406 Also, sleep 1 second after the first aclocal, to work around
11407 problems with sub-second time stamps on the input files.
11409 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11411 * doc/autoconf.texi: Mention "set -e -x" lossage
11412 under node "Limitations of Builtins".
11414 2002-04-29 Akim Demaille <akim@epita.fr>
11416 * doc/install.texi: Better wording for setting variables when
11418 From Christian Cornelssen.
11420 2002-04-29 Akim Demaille <akim@epita.fr>
11422 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11423 of lack of $LINENO support, then the test will compare the $LINENO
11424 in testsuite vs. the lineno in the test file. This is wrong, of
11426 Be sure to protect it.
11427 Reported by Patrick Welche.
11429 2002-04-25 Akim Demaille <akim@epita.fr>
11431 * doc/autoconf.texi (Obsolete Macros): Typo.
11432 Reported by Vladimir Volovich.
11434 2002-04-25 Akim Demaille <akim@epita.fr>
11436 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11437 than some of the input files, hence, on the second run of aclocal,
11438 if some of its input are younger, make them older.
11439 Suggested by Paul Eggert.
11441 2002-04-25 Akim Demaille <akim@epita.fr>
11443 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11448 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
11449 and ac_subst_vars be sh variables containing the list of
11450 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11452 (_AC_INIT_PREPARE): Use them to log them.
11453 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11454 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11455 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11456 _AC_SUBST_FILES and _AC_SUBST_VARS.
11457 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11459 2002-04-24 Akim Demaille <akim@epita.fr>
11461 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11462 autoheader, so that automake does not complain about a missing
11463 config.h.in that was to be created.
11465 2002-04-23 Akim Demaille <akim@epita.fr>
11467 * bin/autoheader.in (parse_args): --warning takes an argument.
11470 2002-04-22 Peter Eisentraut <peter_e@gmx.net>

11517 Minor spelling and grammar fixes.
11519 * doc/autoconf.texi: Follow the outline suggested in the GNU
11520 Sample Texts sections of the Texinfo 4.2 manual. Most
11521 importantly, this makes sure that the copyright notices appear in
11522 all output formats. You probably need Texinfo 4.2 to generate

11562 * doc/autoconf.texi (Shell Substitutions): Explain it.
11563 From Oliver Kiddle and Peter Stephenson.
11565 Have M4sh perform minimal shell sanitizing.
11567 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
11569 (_AS_PREPARE): this new macro.
11571 (AS_INIT): Invoke AS_SHELL_SANITIZE.

11574 Adjust Autoconf and Autotest.
11576 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11577 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.

11579 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

11585 * tests/wrapsh.as: New, precursor of wrapsh.in.
11586 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
11587 on Autotest and M4sh.
11588 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
11589 (wrapsh.in): New target.

11623 Use dnl, not the KILL diversion.
11625 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
11626 (AC_CONFIG_LINKS): here.
11628 Don't use the KILL diversion, as it kills spurious output, which
11629 results in failures being hidden.
11630 Use m4_defn where appropriate.
11631 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11632 after the second argument.
11634 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
11635 syntax, as it is provided by M4sugar.

11677 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11678 to avoid versions of HP C which don't allow that.
11680 2002-03-27 Paul Eggert <eggert@twinsun.com>
11682 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

11696 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11697 as POSIX requires, as it doesn't work with Zsh.
11698 * doc/autoconf.texi (Assignments): Document the problem.
11700 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

11703 about VPATH, overriding of macros in sub-makes, and handling of

11708 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11709 problem with here-document buffer boundaries.
11711 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11712 when reinvoking the shell, to work around problems with installers
11713 who put strange things like "cd" commands in their environments.

11733 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

11737 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11738 (Limitations of Usual Tools): Add mkdir section.
11740 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11741 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11742 back on AS_DIRNAME to compute prefixes otherwise; this is
11743 roughly what mkinstalldirs does. That way, we need not have
11744 our own filename disassembler. The old disassembler did not
11745 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11747 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11748 Create at_test_all by a series of assignments,
11749 not by a single assignment of a long string. The latter causes ksh
11750 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11751 presumably because of a buffer overrun.
11753 2002-03-14 Paul Eggert <eggert@twinsun.com>
11755 * lib/autotest/general.m4 (at_times_skip):
11756 Renamed from at_times. Now a boolean.
11757 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11758 says 'times: not found'.

11799 subdirectory should exist.
11801 2002-03-08 Akim Demaille <akim@epita.fr>
11803 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11805 2002-03-08 Akim Demaille <akim@epita.fr>
11807 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11808 aliases the actual variables, and modifications of the former
11811 2002-03-08 Akim Demaille <akim@epita.fr>
11813 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11814 because of C-c: have m4 output in tmp files, then mv them.

11848 * doc/autoconf.texi (Transforming Names): Equality between target
11849 and host is irrelevant.
11850 (Specifying Names, Canonicalizing): Remove all references to the
11851 backward compatibility hooks. Rather, collect them all into...
11852 (Hosts and Cross-Compilation): this new section.
11853 * doc/install.texi (System Type): Ditto.
11854 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11855 that `--host' implies cross-compilation.

11859 * doc/autoconf.texi (Evaluation Macros): New.
11860 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11862 (_m4_foreach): Define the variant with immediate evaluation so
11863 that it contains exactly the items, not an expression which
11864 evaluation is the current item.
11865 (m4_re_string, m4_re_word): Don't over quote them.
11867 2002-03-04 Akim Demaille <akim@epita.fr>
11869 Instead of having stacking `shift's evaluated at the end, let
11870 `foreach' loops immediately evaluate them.
11872 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11873 $*. This is the n-th time I change my mind, but hopefully this is
11876 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11878 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11879 it was only a hack for m4_text_wrap.
11880 (m4_car2): Remove, replaced by...
11882 (_m4_foreach): Adjust.
11883 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11884 m4_bpatsubst for clarification.

11991 Implement `autom4te --freeze'.
11993 * bin/autom4te.in (&freeze): New.
11994 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11995 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11997 2002-02-05 Akim Demaille <akim@epita.fr>
11999 * bin/autom4te.in (&parse_args): Implement `frozen files are
12000 optional are the sum of the previous files on the command line'.
12001 Also, pass `--reload-state=' on them, so...
12002 (handle_m4): don't.
12003 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12004 (M4sh): Rely on M4sugar.
12005 (Autotest, M4sh, M4sugar): Use frozen files.
12007 2002-01-31 Akim Demaille <akim@epita.fr>
12009 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12010 * doc/autoconf.texi (Initializing configure): Adjust.
12012 2002-01-30 Akim Demaille <akim@epita.fr>
12014 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12015 alphanumeric to `-' instead of `_'.
12017 2002-01-30 Akim Demaille <akim@epita.fr>
12019 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12020 for plain code, the other for cross-compilation code. The latter
12021 is now run with GCC only.
12022 * doc/autoconf.texi (Compilers and Preprocessors): New.
12024 2002-01-30 Akim Demaille <akim@epita.fr>
12026 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

12029 change AC_INIT default values.
12031 2002-01-29 Akim Demaille <akim@epita.fr>
12033 * tests/torture.at (Configuring subdirectories): Use configure.in,
12034 so that aclocal 1.4 works.
12035 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12037 2002-01-28 Akim Demaille <akim@epita.fr>
12039 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12042 2002-01-28 Akim Demaille <akim@epita.fr>
12044 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12045 AUTOTEST_PATH *after* it was set.
12046 Don't put `.' in the PATH: the user should be precise and `./' if
12047 needed. In addition, given that the test suite does some `cd', if
12048 `.' is in the path, the `tested programs' sections will report
12049 programs found in the test suite's directory, while during the
12050 tests (performed in their own directory), these programs are no
12051 longer visible. In other words, the results is confusing and
12053 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
12055 2002-01-24 Akim Demaille <akim@epita.fr>
12059 2002-01-24 Akim Demaille <akim@epita.fr>
12061 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
12062 * doc/autoconf.texi: Finally add Akim as an author.
12064 2002-01-24 Akim Demaille <akim@epita.fr>
12066 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12067 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12068 Bourne. Use /bin/sh.
12069 From Andreas Buening.
12071 2002-01-24 Akim Demaille <akim@epita.fr>
12073 * config/config.guess, config/config.sub, config/texinfo.tex:
12074 Update from masters.
12076 2002-01-24 Akim Demaille <akim@epita.fr>

12081 * config/missing.m4, config/sanity.m4, config/select.m4,
12082 * config/strip.m4: Remove, to ease sync'ing with any version of

12087 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
12088 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
12089 Reported by Geir Ove Myhr.
12091 2002-01-21 Akim Demaille <akim@epita.fr>

12095 2002-01-21 Akim Demaille <akim@epita.fr>
12097 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12098 message on invalid options.
12099 * bin/autom4te.in (parse_args): Don't use
12100 Autoconf::General::getopt with non valid options.
12102 2002-01-17 Jim Meyering <meyering@lucent.com>
12104 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12105 $ac_cv_exeext so we don't use an old, invalid, cached value.
12107 2002-01-11 Akim Demaille <akim@epita.fr>
12109 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

12118 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
12119 package.m4, since is really depends upon configure.ac, not
12121 * doc/autoconf.texi (testsuite Scripts): Adjust.
12122 * tests/Makefile.am (package.m4): New.
12123 EXTRA_DIST it since its a source.
12125 2002-01-06 Akim Demaille <akim@epita.fr>
12127 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12128 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12129 and PACKAGE_BUGREPORT from here...
12130 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12132 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12133 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12134 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12135 * tests/tools.at (autoheader): Adjust.
12136 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
12138 2002-01-06 Akim Demaille <akim@epita.fr>

12151 sometimes needing writable input.
12153 2001-12-17 Jim Meyering <meyering@lucent.com>
12155 * doc/autoconf.texi (New Macros): Tweak wording.
12157 2001-12-14 Akim Demaille <akim@epita.fr>
12159 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12160 trailing files, don't apply `-rf' to files which might not be
12161 created by configure (core, core.*, and *.core), but just `rm -f'.
12162 Suggested by Jonathan Kamens.
12164 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12166 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12168 2001-12-14 Akim Demaille <akim@epita.fr>
12170 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12172 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
12174 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
12175 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12176 abs_srcdir, top_srcpath to abs_top_srcdir.
12177 (_AC_OUTPUT_FILES): Adjust.
12178 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
12179 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12180 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12182 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

12186 search path from the LPATH line in the $F77 -v output.
12188 2001-12-12 Kevin Ryde <user42@zip.com.au>
12190 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12191 forbidden file descriptors table.
12193 2001-11-26 Akim Demaille <akim@epita.fr>
12195 * bin/autoscan.in (%c_keywords): Build it at top level.
12196 Map to 1 in order to simplify its uses.
12198 2001-11-26 Akim Demaille <akim@epita.fr>
12200 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12201 Remove $filepath, useless.
12202 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12203 variables, they are really part of the tokens.
12204 Split the input line on spaces and then look for tokens.
12205 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12206 because of `lex$U.$(OBJEXT)'.
12207 (&scan_files): Use "@list" instead of join.
12208 * doc/Makefile.am (CLEANFILES): Add *.fns.
12210 2001-11-26 Akim Demaille <akim@epita.fr>

12213 Remove, replaced by...
12214 * tests/wrappl.in: Be common for all the Perl executables.
12215 In particular autoscan and autoheader want -I.
12216 * configure.ac: Adjust.
12217 * lib/autoscan/headers: errno.h is portable.
12219 2001-11-26 Akim Demaille <akim@epita.fr>
12221 * bin/autoscan.in (used): New.
12224 2001-11-26 Akim Demaille <akim@epita.fr>
12226 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12228 (&scan_sh_file): Remove a duplicate pattern.
12229 (&check_configure_ac): Use long options.
12230 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

12235 Before, having a line containing the opening of a multi line
12236 comment made the whole line be ignored.
12238 2001-11-26 Akim Demaille <akim@epita.fr>
12240 * doc/autoconf.texi (Using an Autotest Test Suite): New.
12241 (testsuite Scripts): Be one of its subsection.
12242 (Autotest Logs): New.

12246 Test groups are now run two directories deeper.
12248 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12249 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12251 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12252 top_srcdir, builddir and top_builddir.
12253 Use `at_*dir' relatively to the directory containing the
12254 suite, use `*dir' when relatively to the current group dir.
12256 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12258 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12259 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12260 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12263 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12265 * doc/autoconf.texi (Using System Type): Add an example of `case
12266 $host' usage so people quit using `case $target' everywhere.
12268 2001-11-22 Akim Demaille <akim@epita.fr>
12270 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12271 spotted by Jim Meyering.
12273 2001-11-16 Paul Eggert <eggert@twinsun.com>
12275 This patch implements a `long double' suggestion by Oliver Kiddle.
12277 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12278 static, to catch errors if the value isn't known at compile-time
12279 and the compiler supports dynamic arrays. Change its name from
12280 `_array_' to `test_array' to avoid potential name clashes.
12281 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12282 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12283 better than double. Catch a bug in GCC 2.95.2 x86.
12284 * doc/autoconf.texi (C Compiler): Document the above.
12287 2001-11-13 Akim Demaille <akim@epita.fr>
12289 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12291 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12293 2001-11-13 Akim Demaille <akim@epita.fr>
12295 * lib/autotest/general.m4 (AT_INIT): After having run the test
12296 group, go back to the initial directory, not to at_suite_dir.
12298 2001-11-13 Akim Demaille <akim@epita.fr>
12300 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12301 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12302 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12304 (AT_CHECK_CONFIGURE): Use absolute paths.
12305 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12306 The problem is still the old one: there is no means in M4 (that I
12307 know about) to create a defining macro, because there is no means
12308 to create `$1' etc., therefore, the defining macro ``swallows''
12309 all the arguments meant to the defined macro.
12311 2001-11-13 Akim Demaille <akim@epita.fr>
12313 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12314 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12316 * tests/aclocal.m4: Remove, as it is no longer used.
12318 2001-11-13 Akim Demaille <akim@epita.fr>
12320 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12321 variable names when referring to a single test group, or to
12322 `suite' when referring to the whole test suite.
12323 `at_last_test' is removed: m4 compute at_format itself.
12324 (at_stdout, at_stder1, at_stderr): New variables.
12325 (AT_CHECK): Use them.
12327 2001-11-13 Akim Demaille <akim@epita.fr>
12329 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12331 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12332 Do it as soon as a test fails, don't wait till the end of the test
12334 Don't remove $as_me.[0-9]*, since these files no longer exist.
12336 2001-11-13 Akim Demaille <akim@epita.fr>
12338 * tests/tools.at: Use absolute paths, since we are no longer run
12341 2001-11-13 Akim Demaille <akim@epita.fr>
12343 Now that tests are running in their own private dir, there is no
12344 need to list the files to remove at the end of tests groups.
12346 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12347 (AT_data_files, at_data_files): Remove.
12348 (AT_CLEANUP, AT_DATA): Simplify.
12350 Remove the group dir if !debug && !failed.
12351 * tests/atspecific.m4: Adjust.
12353 2001-11-13 Akim Demaille <akim@epita.fr>
12355 Start a new layout for Autotest: `testsuite' creates
12356 `testsuite.dir' in which the at-check-line etc. files are to be
12357 found, and `testsuite.dir/003' where the test group 3 is run.
12359 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12360 at_check_line_file, at_format, at_test_normalized, at_group_dir
12362 Create the directories.
12363 Use absolute paths for at- files.
12364 (AT_CHECK): Adjust.
12366 2001-11-11 Michael Matz <matz@kde.org>
12368 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12370 (m4_car): Properly quote arguments.
12372 2001-11-13 Akim Demaille <akim@epita.fr>
12374 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12375 with stricter rules on LIBOBJS.
12377 2001-11-12 Paul Eggert <eggert@twinsun.com>
12379 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12380 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12383 2001-11-12 Akim Demaille <akim@epita.fr>
12385 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12387 2001-11-12 Akim Demaille <akim@epita.fr>
12389 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12390 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12391 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12392 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12393 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12394 specify to what the macro should be defined (typically to 1).
12396 2001-11-12 Akim Demaille <akim@epita.fr>
12398 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12401 2001-11-12 Akim Demaille <akim@epita.fr>
12403 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12404 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12405 definition used by Automake where LEX is +/- "${missing} lex" and
12406 `missing' itself contains variables.
12408 2001-11-12 Akim Demaille <akim@epita.fr>
12410 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12411 Now that M4sh pushes BODY, the comments were output at the end of
12414 2001-11-08 Akim Demaille <akim@epita.fr>
12416 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12417 that we can trace macros from aclocal.m4.
12418 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12419 obsoleted, and redirect to the former anyway.
12420 Reported by Ralf Corsepius.
12422 2001-11-08 Akim Demaille <akim@epita.fr>
12424 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12425 processed only if present.
12426 * tests/torture.at (Configuring subdirectories): Use autoreconf
12427 instead of successive calls to autoconf.
12428 Add a nonexistent subdirectory to exercise the patch above.
12429 Reported by Ralf Corsepius.
12431 2001-11-08 Kevin Ryde <user42@zip.com.au>
12433 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12434 doesn't accept .S files.
12436 2001-11-07 Akim Demaille <akim@epita.fr>
12438 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

12440 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
12441 * bin/autom4te.in (warn_forbidden): New.
12442 (handle_output): Use it.
12443 Read m4_pattern_forbid with messages.
12445 2001-11-05 Akim Demaille <akim@epita.fr>
12447 * bin/autom4te.in (--normalize): Remove.
12448 * lib/autom4te.in: Adjust.
12450 2001-11-05 Akim Demaille <akim@epita.fr>
12452 * tests/Makefile.am (testsuite): Rename this target as...
12453 ($(TESTSUITE)): this.
12456 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12458 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12459 the --prefix option, also remove it's argument.
12461 2001-11-05 Akim Demaille <akim@epita.fr>
12463 * doc/autoconf.texi (testsuite Invocation): Update.
12464 (Writing testsuite.at): Update.
12466 2001-11-03 Akim Demaille <akim@epita.fr>
12468 * doc/autoconf.texi: s/@code/@command/ where appropriate.
12470 2001-11-03 Akim Demaille <akim@epita.fr>
12472 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12473 (&file_name_is_absolute): New, wrappers around routines from
12475 Use and export them.
12476 (&find_configure_ac): Optionally take a directory where to look at.
12477 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12479 Default @ARGV to `.', not find_configure_ac.

12481 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12482 * doc/autoconf.texi (autoreconf Invocation): Update.
12484 2001-11-03 Akim Demaille <akim@epita.fr>
12486 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12487 (@export_forward_subs): New.
12488 Add basename, dirname, and fileparse.
12490 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12491 Don't look for aclocal flags if we already know aclocal is not
12493 Move aclocal.m4t only if it exists.
12494 Reported by Ezra Peisach.
12496 2001-11-03 Akim Demaille <akim@epita.fr>
12498 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12499 passed on command line, defaulting to ./configure.ac if present.
12500 (&maybe_autoreconf, File::Find): Remove, unused.
12501 (&autoreconf): If autoconf is not used, don't try to trace.
12503 2001-11-02 Akim Demaille <akim@epita.fr>
12505 * configure.ac: Bump to 2.52g.
12507 2001-11-02 Akim Demaille <akim@epita.fr>
12511 2001-11-02 Akim Demaille <akim@epita.fr>
12513 * config/config.guess, config/config.sub, doc/standards.texi:
12514 * config/lispdir.m4: Update from masters.
12515 * configure.ac: Bump to 2.52f.
12517 2001-11-02 Akim Demaille <akim@epita.fr>
12519 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12520 Don't run aclocal when aclocal.m4 is not from aclocal.
12522 Don't run libtoolize and gettextize if --install is not given.
12524 2001-11-01 Paul Eggert <eggert@twinsun.com>
12526 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12527 be invoked before _AS_LINENO_PREPARE.
12528 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12529 than character ranges.
12531 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12532 invoking AS_BASENAME. Set the locale variables to 'C' if
12533 possible, as POSIX requires this to get the traditional
12535 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12537 2001-10-31 Paul Eggert <eggert@twinsun.com>
12539 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12540 with {}, as that triggers a bug in Bash 2.05.
12542 (_AS_LINENO_PREPARE): Use Sed rather than
12543 Awk. Fix the sed prepass to work even if there are multiple
12544 instances of $LINENO on the same line. Do not substitute for
12545 other variables like $LINENOT. Do not check file dates; such a
12546 check is unreliable on sufficiently fast machines, and removing
12547 the check makes the code simpler and more reliable. Check for
12548 output and chmod failures.
12550 * doc/autoconf.texi (Special Shell Variables): Document
12553 2001-10-31 Akim Demaille <akim@epita.fr>

12558 2001-10-31 Akim Demaille <akim@epita.fr>
12560 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12561 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12562 provided, while it is optional.
12563 * configure.ac: Adjust.
12565 2001-10-26 Paul Eggert <eggert@twinsun.com>
12567 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12568 lib/Autom4te/Struct.pm:
12569 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12572 * doc/autoconf.texi (Special Shell Variables): Document some
12573 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12575 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12576 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12577 eval $LINENO is not portable in practice.
12579 2001-10-24 Akim Demaille <akim@epita.fr>
12581 * lib/Autom4te/General.pm (backname): New.
12583 2001-10-24 Akim Demaille <akim@epita.fr>

12591 2.05's use of ANSI quoting in its `set' builtin.
12593 2001-10-22 Paul Eggert <eggert@twinsun.com>
12595 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12596 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12597 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12598 POSIX decided to standardize on the int flavor of strerror_r.
12599 Always do char* test, as there's no reason not to.
12600 Assign to a char* var, to catch strerror_r that returns int*.
12602 * doc/autoconf.texi (Particular Functions):
12603 Document the above changes. Also, document the fact that
12604 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12606 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12608 2001-10-20 Akim Demaille <akim@epita.fr>

12613 2001-10-20 Akim Demaille <akim@epita.fr>
12615 * lib/Autom4te/General.pm (&update_file): If destination is
12616 unchanged, remove the source.

12618 * bin/autoreconf.in: No longer support --m4dir.
12619 (&autoreconf): Display the full path of the configure.ac we are
12621 Trace it only once.
12622 Be sure to honor --force with gettextize.
12623 Always run aclocal.
12624 * doc/autoconf.texi: Adjust.
12626 2001-10-20 Akim Demaille <akim@epita.fr>
12628 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12630 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12631 `intl' is already present, as it refuses unless --force.
12632 (&parse_args): Use -I, --include instead of the old Autoconf
12634 ($localdir, $autoconf_dir): Remove.
12636 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12638 2001-10-19 Jens Petersen <petersen@redhat.com>
12640 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

12653 comment, explain how to install automatic mode selection.
12656 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
12658 * bin/autoreconf.in (autoreconf): Display the path to the
12659 configure.ac being studied.
12661 2001-10-18 Paul Eggert <eggert@twinsun.com>
12663 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
12664 long, to work around a bug in the HP C compiler version HP92453-01
12667 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
12668 (AS_BASENAME_EXPR): New macro.
12669 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12670 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
12671 and fall back on 'sed' only if the other two fail. This makes
12672 AS_BASENAME act more like AS_DIRNAME.
12673 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
12674 contains white space.
12675 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
12676 Use AS_DIRNAME, since I think it's now DOS-friendly.
12677 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
12678 Allow "dirname //FOO" to return either / or //, as POSIX allows

12683 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

12689 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

12729 bother with $force since...
12730 * lib/Autom4te/General.pm: does.
12732 2001-10-08 Akim Demaille <akim@epita.fr>
12734 * bin/autoreconf.in: Rewrite in Perl.
12735 * configure.ac: Adjust.

12819 empty, and if we can find a shell that does support LINENO,
12820 then set CONFIG_SHELL to that shell and then re-execute
12821 ourselves with CONFIG_SHELL.
12823 2001-10-05 Paul Eggert <eggert@twinsun.com>
12825 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
12826 doesn't exist. Remove *.tmp, as a .tmp file is created during the

12897 Don't use nested parenthesization. This patch was originally

12899 but somehow it didn't get incorporated then.
12900 * doc/autoconf.texi (Limitations of Usual Tools):

12906 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12907 Check for `expr' arithmetic overflow, and for compilation failure,
12908 and invoke a new argument $4 if either is discovered.
12909 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
12910 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
12912 2001-09-28 Akim Demaille <akim@epita.fr>
12914 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

12944 * tests/fortran.at (GNU Fortran 77): there.

13135 (Limitations of Usual Tools): Refer to it when discussing dirname.
13136 Also, update discussion of POSIX standard to reflect latest draft.

13139 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13141 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13142 Do not pass a first argument with leading '-'
13143 to expr, by parenthesizing initial integers that might be negative.
13145 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13146 now merely checks whether it is an error to pass an argument
13149 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13150 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13151 whether it is a (compile-time) error to pass an argument to

13169 Add test for AS_BASENAME.
13170 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13171 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13172 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13173 * tests/base.at: Fixed the expected responses. The old ones were
13175 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13176 the documentation claims it should (and how it behaved in 2.13).
13178 2001-09-18 Akim Demaille <akim@epita.fr>
13180 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13181 the AC_CONFIG_COMMANDS invocation.

13185 No longer to be shipped.

13189 Use `m4_PACKAGE_STRING'.
13190 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13191 the only optional argument is the name of the test suite.
13192 Expect `package.m4' to define the package signature.
13193 * lib/autom4te.in (Autotest): Add `package.m4?'.
13194 * tests/Makefile.am (package.m4): New.

13214 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13215 Always include <stdio.h> and <stdlib.h>. Evaluate
13216 the expression in an extra function before these includes. Call
13217 fprintf "%d" only after ensuring the argument is of type 'int'.
13218 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13220 2001-09-17 Paul Eggert <eggert@twinsun.com>
13222 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13223 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13224 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13225 when they don't exist.
13227 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13228 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13231 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13232 version with the version used by fileutils 4.1, except use

13278 * lib/autotest/general.m4 (AT_INIT): Create and remove
13279 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13280 test suites can cohabit.

13284 * tests/mktests.sh: Don't output banners for empty test files.

13390 2001-09-05 Akim Demaille <akim@epita.fr>
13392 Be ready to handle filenames as stupid as `dnl.at', for if even
13393 the maintainer is dumb enough to do that...
13395 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13396 excellence in M4 quotation: consider `__file__' is active.
13398 And BTW, when invoking m4, pass the --include in the right order:

13422 * doc/autoconf.texi (autoscan Invocation): Adjust.
13424 2001-09-05 Akim Demaille <akim@epita.fr>
13426 CVS GNU M4 doesn't like `undefine(undefined)'.
13428 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
13429 New, extracted from main.
13430 Use IO::File wherever possible.
13431 (input.m4): Be constant, use -I instead of hard coding $tmp.
13432 Therefore be a quoted heredoc.
13433 Don't invoke `_au_disable', since ac was not loaded, but just

13459 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
13461 2001-08-31 Akim Demaille <akim@epita.fr>
13463 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
13464 (testsuite Scripts): There is no such thing as `atconfig.in'.
13465 And actually one diagram is missing: test suite runtime.
13467 2001-08-31 Akim Demaille <akim@epita.fr>
13469 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
13472 2001-08-31 Akim Demaille <akim@epita.fr>
13474 * bin/autoupdate.in (@include): `installcheck' revealed the path
13475 to m4sugar was lacking!
13477 2001-08-31 Akim Demaille <akim@epita.fr>
13479 * man/Makefile.am (.x.1): We really have to pass
13480 autom4te_perllibdir.

13490 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
13491 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
13492 Use directly autom4te, not autoconf.

13495 2001-08-31 Akim Demaille <akim@epita.fr>

13517 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
13518 (autoheader): Pass --force since the test suite goes too fast for
13520 Adjust to the new autoheader messages.
13522 2001-08-31 Akim Demaille <akim@epita.fr>
13524 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

13534 Drop AC_MACRODIR dead for real.
13535 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
13536 `autoheader: `config.hin' is created'.
13537 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
13539 2001-08-31 Akim Demaille <akim@epita.fr>
13541 * bin/autoheader.in: Rewrite in Perl.
13542 * tests/autoheader: Adjust.
13544 2001-08-31 Akim Demaille <akim@epita.fr>

13547 Map --localdir, --autoconf-dir onto it.
13548 Forward autom4te's options instead of interpreting them.
13549 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
13550 There is no such envvar since the inception of autom4te.cfg.
13551 * bin/autom4te.in (&parse_args): Uniquify `@include'.
13552 * bin/autoupdate.in: Adjust, and perform more control.

13554 * tests/autoconf: Dittowise.
13556 2001-08-31 Akim Demaille <akim@epita.fr>
13558 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
13559 * bin/autom4te.in (&find_file): Support `FILE?' standing for
13561 Use -e, not -f, since /dev/null for instance is OK.
13562 (&parse_args): Adjust.
13563 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
13565 2001-08-31 Akim Demaille <akim@epita.fr>

13572 * lib/Autom4te/General.pm (&find_peer): Remove.
13573 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
13574 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
13575 * man/Makefile.am: Let help2man rely on PATH instead of trying to
13576 find the executables for it.
13577 * tests/Makefile.am: Major cleanup. Too lazy to document...
13578 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13580 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13581 indeed related to running the test suite, while passing
13582 --autoconf-dir and others is related to running non installed
13583 Autoconf executables. So don't do that, leave it to...
13584 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
13585 * tests/autoscan: New.
13586 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

13602 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
13603 Suggested by Paul Eggert.
13605 2001-08-29 Akim Demaille <akim@epita.fr>
13607 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
13608 download in a tmp dir.
13610 2001-08-29 Akim Demaille <akim@epita.fr>
13612 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

13632 foo=`(command) 2>/dev/null`

13636 (AT-devnull): this.

13783 the name of the directory they're in, instead of the filename,

13872 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
13873 * NEWS, README, README-alpha, TODO, tests/README: This package is
13874 `Autoconf', not `autoconf' (the executable).
13876 2001-08-20 Akim Demaille <akim@epita.fr>
13878 Info readers seem to need `Index' in the index node title :(

13931 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

13994 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

14012 * doc/autoconf.texi: Work around Texinfo buglets.
14013 (Transformation Rules): One example is enough, users are expected
14014 to have their brains on. And BTW, use DESTDIR.
14015 (dvar): New macro. Use it.
14017 2001-08-17 Akim Demaille <akim@epita.fr>
14019 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

14072 autom4te.cache (it's a directory, not a file.
14073 * Makefile.am: Ditto (but maintainer-clean-local).
14075 2001-08-15 Akim Demaille <akim@epita.fr>
14077 * bin/autom4te.in (@m4_warning): New.
14078 (&handle_m4): Use it.
14079 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14080 warnings are issued at each run.
14081 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14082 is in the src tree.
14084 2001-08-15 Akim Demaille <akim@epita.fr>
14086 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
14087 don't waste time running `autoupdate --version' works.
14088 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
14090 2001-08-13 Akim Demaille <akim@epita.fr>

14149 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14151 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14152 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14153 * doc/autoconf.texi (C Compiler Characteristics): Update
14154 documentation for AC_C_BIGENDIAN.
14156 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

14159 magic values from an object file when cross-compiling.
14160 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14162 2001-08-10 Akim Demaille <akim@epita.fr>
14164 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14166 Suggested by Russ Allbery.
14168 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14170 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14171 current $prefix to the sub-configures.
14173 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14175 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14176 extension (needed on BeOS). Reported by Guido van Rossum.
14178 2001-08-09 Akim Demaille <akim@epita.fr>
14180 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14182 2001-08-07 Akim Demaille <akim@epita.fr>
14184 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14186 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14187 No need to remove the files before and after the each test, before
14188 each test and at the end of the suite is enough.
14189 Display only the children `times', not the shell's.
14190 If the test failed or was skipped, at-times is not available.
14192 2001-08-07 Akim Demaille <akim@epita.fr>
14194 Always produce testsuite.log, including when there are no
14195 failures. This helps getting information on skipped tests, and
14196 duration of the tests. Err, implement the latter btw.
14198 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14199 Dump information on the first run of each test.
14200 (AT_CLEANUP): Create `at-times' containing the duration of the
14203 2001-08-07 Akim Demaille <akim@epita.fr>
14205 The use of `dumpstat' revealed that `len' was used although it
14206 should not. m4_text_wrap was using it, but in the Autoconf world
14207 where it is legal. Hence (i) test M4sh in its own world, not
14208 Autoconf's, and (ii), ahem, fix the bug :)
14210 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14211 does not like `' instead of [].
14212 (AT_INIT): Forbid `^_?AT_'.
14213 And don't output such tokens.
14214 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14215 `script.as', and `autom4te.cache'.
14216 Remove `empty' and `macro' which are no longer used.
14217 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14218 * tests/m4sugar.at: Use it.
14219 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14221 2001-08-07 Akim Demaille <akim@epita.fr>

14225 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14227 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14229 2001-08-04 Akim Demaille <akim@epita.fr>
14231 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14232 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14234 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14235 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)

14238 2001-08-04 Akim Demaille <akim@epita.fr>
14240 Don't rely on M4sugar outputting the patterns in files, since we
14241 might process the output _without_ running m4, hence without these
14244 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14245 * bin/autom4te.in (@Request::includes): Remove, unused.
14246 (@Request::source): Rename as...
14247 (@Request::input): this.
14248 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14249 (&handle_output): Fetch the patterns from the traces.
14250 `$forbidden' and `$allowed' are constant: use m//o.
14251 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14252 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14254 2001-08-04 Akim Demaille <akim@epita.fr>
14256 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14257 autoconf', i.e., in addition to caching traces, cache the output.
14259 * bin/autom4te.in (Request::cache): Rename as...
14260 (Request::id): this.
14261 ($cache, $icache, $tcache, $ocache): New.
14262 (&handle_m4): Save M4 output in the cache instead of $tmp.
14263 (&handle_output): Adjust.
14264 (&up_to_date_p): Check that the output cache is up to date too.
14265 (top level): Run `&handle_m4' iff force or the cache is invalid.
14266 Run `&handle_output' if the output cache is more recent.
14268 2001-08-04 Akim Demaille <akim@epita.fr>
14270 * bin/autom4te.in ($force): New.
14271 (&parse_args, &print_usage): -f, --force is a new option.
14272 (&handle_output): CPP directives might have spaces after `#'.
14273 (&parse_args): The first file only can be frozen.
14275 2001-08-04 Akim Demaille <akim@epita.fr>
14277 Don't let autom4te compute the `include' traces several times:
14278 first check that the trace cache file is up to date, and then
14279 compare its timestamp with that of the output.
14281 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14282 the preamble. Don't require 5.005 as Autom4te::General does it,
14283 and better yet (use `use', not `require'!).
14284 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14285 Class::Struct as Autom4te::Struct.
14286 * lib/Autom4te/General.pm (File::stat): Use it.
14287 (&mtime): New, export it.
14288 * bin/autom4te.in: Use it.
14289 Declare `$req' is invalid if it is outdated.
14290 Don't declare it valid before saving it if something went wrong.
14292 2001-08-04 Akim Demaille <akim@epita.fr>

14295 must be proposed to the users.
14297 * bin/autom4te.in (@required_trace): Remove.
14299 (&parse_args, &print_usage): -p, --preselect is a new option.

14305 * tests/tools.at (autoconf --trace: user macros): Check traces on
14306 macros invoked without arguments, and macros invoked with multiple

14316 * bin/autoconf.in ($@): Work around the usual sh bug.
14319 2001-08-03 Akim Demaille <akim@epita.fr>
14321 Clean up the handling of the M4 builtins tracing exception.

14326 (@m4_builtin): this.
14327 (%m4_builtin_alternate_name): New.
14328 (&parse_args): Complete the trace requests with alternate names.

14335 m4_if, and m4_wrap.
14337 2001-08-03 Akim Demaille <akim@epita.fr>
14339 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
14340 (m4_divert_pop): Dump the whole diversion stack when a diversion
14342 * bin/autom4te.in (&handle_output): Remember of the first
14343 occurrence of a possibly undefined macro, not the last.
