20 2008-03-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
22 On MinGW, substitution of CR and 0xFF fails.
23 * tests/torture.at (Substitute and define special characters):
24 MinGW awk cannot handle 0xFF, and on MinGW, the test does the
25 wrong thing for CR.
27 2008-03-04 Eric Blake <ebb9@byu.net>
29 Pull in recent maintainer improvements from coreutils.
30 * GNUmakefile (_is-dist-target): 'make distclean' should not
31 trigger autoreconf.
32 (_dummy): Change directories before removing autom4te.cache.

83 * GNUmakefile: Merge from coreutils.
84 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
85 not .version.
86 * configure.ac (AC_INIT): Use .tarball-version, not .version.
87 * build-aux/git-version-gen: Update from gnulib.
89 2008-03-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

103 Be nice with file systems that don't handle unusual characters.
104 * tests/atlocal.in (func_sanitize_file_name)
105 (func_sanitize_dir_name): New shell functions.
106 * tests/tools.at (autom4te and whitespace in file names)
107 (autotools and whitespace in file names): Use them.

109 Cover more potentially problemtic file names. Use the new
110 functions.
112 Properly handle funny file names for headers in config.status.
113 The test suite did not cover this bug because the code was not
114 quoting properly the arguments of `rm -f' (which "fails" silently)
115 as well as the arguments of `diff' (whose output was redirected to
116 /dev/null so we couldn't see its error message).
117 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
118 file names passed to `rm' and `diff'.
119 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
120 Add a regression test.
122 2008-03-01 Benoit Sigoure <tsuna@lrde.epita.fr>

131 2008-03-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
133 Ignore errors from ./run on w32.
134 * tests/autotest.at (whitespace in absolute testdir):
135 Ignore stderr for `./run' which fails to remove the
136 busy test directory on w32.
138 2008-02-22 Eric Blake <ebb9@byu.net>
140 Improve documentation for writing autotest suites.

175 * lib/autotest/general.m4 (AT_INIT): Fix --clean to work
176 again, broken since introduction of `-C dir'.
177 * tests/autotest.at (Choosing where testsuite is run): Test it.
179 2008-01-30 Paul Eggert <eggert@cs.ucla.edu>
181 * doc/autoconf.texi: Update Back-Cover text to reflect new GNU wording.
183 2008-01-29 Eric Blake <ebb9@byu.net>
185 Fix more autotest regressions.
186 * lib/autotest/general.m4 (AT_LINE): Fix regression from
187 2007-10-04 when file name is `dnl'.

199 More corner cases in testsuite VAR=VALUE handling.
200 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS): Fix quoting
201 bug.
202 <PARSE_ARGS_END>: Also detect leading digits in assignments.
203 * tests/autotest.at (Using atlocal): Enhance test to catch last
204 bug.

207 bug.
209 2008-01-28 Eric Blake <ebb9@byu.net>
211 Fix regression in handling VAR=VALUE arguments to testsuite.
212 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect
213 leading = as invalid. Defer use of command-line variable
214 assignments...

224 BSD behavior on binary input.
226 Minor testsuite improvements.
227 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
228 forks when sanitizing PATH. Always output machine information,
229 not just when atconfig was located.
231 Add 'testsuite -C dir'.
232 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
233 detection...
234 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
235 argument.
236 <DEFAULTS>: Delay computation of variables based on $at_dir...
237 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
238 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
239 <PARSE_ARGS>: Parse new option.
240 <HELP_TUNING>: Document it.
241 * tests/autotest.at (Choosing where testsuite is run): New test
242 for this feature.
243 (Keywords and ranges): Add test for missing -k argument.
244 * NEWS: Document this.
245 * doc/autoconf.texi (testsuite Invocation): Likewise.
247 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
249 * build-aux/config.guess, build-aux/config.sub,
250 build-aux/texinfo.tex: Sync from gnulib.
251 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
252 Likewise.
254 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
256 * doc/autoconf.texi (Particular Programs): Do not mention the
257 Autoconf version in which the AC_PROG_INSTALL change was done.
258 Suggested by Paul Eggert.
260 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
262 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
263 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
264 mode, we change to the source directory, also set $ac_pwd so we
265 do not go back to the build tree for the next config subdir.
266 * tests/torture.at (Deep Package): Extend test to contain two
267 config subdirs on the top level.
269 Fix parallel `maintainer-check'.
270 * Makefile.am (maintainer-check-tests): Depend on `all'.
271 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
272 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):

298 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
300 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
301 check_SCRIPTS. Building the wrappers for `all' allows help2man
302 to use them for the manpages.
303 Report by Benoit Sigoure.
305 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
307 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
309 Fix some write failure cases in Autotest.

319 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
320 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
321 (m4_require): Use m4_do, not m4_join.
323 Fix some whitespace tests on cygwin.
324 * tests/tools.at (autom4te and whitespace in file names): Restore
325 font-lock. Create $TMPDIR before it might be used.
327 Fix spurious testsuite failure with M4 1.4.11.
328 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
330 Optimize AC_REQUIRE.
331 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
332 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
333 (m4_require): Avoid extra macro calls.
335 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
337 * tests/torture.at (srcdir): Fix quoting.
339 Do not pass top_srcdir to configure scripts in testsuite.
340 * tests/autotest.at (srcdir propagation): Copy install-sh to
341 source tree.
342 (my only test): Drop setting of `top_srcdir'.
343 * tests/base.at (Input/Output): Likewise.
344 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
345 config.guess, and config.sub to test source tree.
346 Drop AC_CONFIG_AUX_DIR setting.
347 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
348 * tests/torture.at (Substitute a 2000-byte string): Drop
349 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
350 (Substitute a newline, datarootdir workaround): Likewise.
351 (Define a newline): Adjust for linenumber changes in configure.ac.
352 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
354 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
355 if `pwd` contains whitespace.
357 Quote $abs_top_srcdir in tests.
358 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
359 * tests/tools.at (Syntax of the shell scripts): Likewise.
361 * tests/m4sh.at (LINENO): Quote $0.
363 Fix testsuite program wrapper for whitespace in `pwd`.
364 The problem here is that the usual mantra is that command
365 variables can contain arguments, thus we cannot just escape
366 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
367 $top_builddir/tests directory early in $PATH, so that the
368 wrappers are found by their plain name.
369 * tests/wrapper.as: Put $testdir early in $PATH.
370 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
372 Proper config.status --file/--header and $srcdir escaping.

378 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
380 Fix Autotest for whitespace in `pwd`.
381 * lib/autotest/general.m4 (AT_INIT)
382 <at_func_create_debugging_script, Driver Loop>:
383 Quote $at_group_dir.
384 * tests/autotest.at (whitespace in absolute testdir): New test.
386 * lib/autom4te.in: Quote @datadir@.
388 Proper file name escaping in Autoconf programs and Perl modules.
389 This includes escaping of characters special to the shell
390 as well as special to Perl, e.g., leading `<' or `>'.
391 For example, when $file starts with `>', `open ">$file"'
392 wrongly tries to append to a different file.
393 * bin/autoconf.as: Fix quoting for autom4te options.
394 * lib/Autom4te/General.pm (shell_quote): New function, taken
395 from coreutils, written by Jim Meyering.
396 (mktmpdir): Use it.
397 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
398 and open_quote.
399 * bin/autoreconf.in (parse_args): Likewise.
400 * bin/autoscan.in (main): Likewise.
401 * bin/autoupdate.in (main): Likewise.
402 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
403 * bin/ifnames.in: Likewise, XFile usage fixes.
404 * tests/tools.at (autom4te and whitespace in file names): Extend
405 test. Test twice, with special characters allowed on w32, and the
406 rest. Test leading and trailing whitespace, for `open_quote'.
407 (autotools and whitespace in file names): New, analogous test.
408 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
409 by Russ Allbery and Eric Blake.
411 Sync from Automake.
412 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
413 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
414 * lib/Autom4te/FileUtils.pm (open_quote): New function.
415 (update_file, contents): Use it.
417 * Makefile.am (autom4te-update): Rewrite for git.
419 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
421 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
423 Fix copyright years.
424 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
425 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
427 2007-12-04 Eric Blake <ebb9@byu.net>
429 Manually resync with gnulib, since 'make cvs-update' no longer works.
430 * build-aux/config.guess: New upstream version.
431 * build-aux/config.sub: Likewise.
433 When using older automake, don't downgrade build-aux/texinfo.tex.
434 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
435 * doc/Makefile.am (TEXINFO_TEX): Add.
437 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
439 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
440 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
441 #undef as this runs afoul of our new way of creating config.h.
442 Problem reported by Jim Meyering in
443 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
445 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
447 Fix autom4te for unusual characters in input file names.
448 * bin/autom4te.in (files_to_options): Quote active characters
449 for the shell.
450 * tests/tools.at (autom4te and white space in file names):
451 New test.
453 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
454 Document that Tru64 awk always splits $0.
456 2007-11-24 Stepan Kasal <kasal@ucw.cz>
458 * lib/autotest/general.m4 (AT_INIT): Do not extract the
459 `#AT_STOP_...' line at the end of each test.
461 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
463 * lib/autotest/general.m4 (AT_INIT): For awk line number
464 extraction script, ensure `$at_group' has a defined value
465 even for the empty set, and properly quote its usage inside
466 the awk script.
468 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
470 * doc/autoconf.texi (Shell Functions): New chapter. Document
471 IRIX sh $0 issue in functions, move content from ...
472 (Portable Shell): ... here.
473 (Shell Script Compiler): Note that shell functions are not
474 totally unportable any more.
476 2007-11-22 Stepan Kasal <kasal@ucw.cz>
477 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
479 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
480 extracting the line numbers of the last needed test.
482 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
484 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
485 Fix quoting.
487 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
489 Fix IRIX testsuite debugging failures: $0 in functions.
490 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
491 Do not use $0 inside a function, as IRIX sh will set that to the
492 function name rather than the script invocation name.
494 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
495 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
497 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
498 to extract test scripts.
499 (AT_INIT): Extract and cache test script line numbers.
501 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
503 * lib/autotest/general.m4: Revert 2007-11-15 patch and
504 subsequent fixups; the awk -> here-document conversion trashes
505 performance too much with AIX sh.
507 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
509 * tests/local.at: Do not test m4, perl with AT_TESTED.
511 Diagnose and guard against write errors dealing with config.status.
512 The general idea is this: all write failures from `configure'
513 writing `config.status' are indicated by $ac_write_error, which
514 is only checked at the end. This is safe because config.status
515 code is not executed before the file is complete. Other write
516 failures, be they inside config.status, or in sub shell/awk
517 scripts spawned from configure or config.status, typically need
518 earlier checking, as their results are used right afterwards.
519 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
520 before writing config.status, check afterwards.
521 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
522 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
523 Set `ac_write_error' for write failures to config.status. Barf
524 upon write failures to temporary files.
525 Adjust note about closing and reopening the here-document.
526 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
527 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
528 reopening the here-document.
529 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
530 Ensure `ac_write_error' does not escape into config.status.
531 Also, add a couple of code paths not yet exercised in the test
532 suite: a config file with input from stdin, and a config header
533 output to stdout.
534 Suggestion for catching write errors by Bruno Haible.
536 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
538 Avoid error with Tru64 awk and testsuite lines with many words.
539 * lib/autotest/general.m4 (AT_INIT): In the awk script that
540 reads the testsuite, set the field separator to an unusual value,
541 in order to not run over the limit of 199 fields. Tru64 4.0D awk
542 even splits the input if $i, i>0, was never accessed in the script.
544 Revert 2007-10-17 change.
545 * TODO: Multiline args in config files and headers mean something
546 different and are not fixed, see

552 2007-11-16 Stepan Kasal <kasal@ucw.cz>
554 AC_*_TOOL does not canonicalize the prefix
555 * doc/autoconf.texi (Generic Programs): Do not say that
556 the *_TOOL macros canonicalize, they simply use the `host_alias'.

560 Diagnose write errors in config.status instantiations.
561 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
562 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
563 on write errors.
564 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
565 Extend test to also check for some write error failures, using...
566 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
567 Report by Bruno Haible.
569 Indentation fixups.
570 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

578 (_AC_OUTPUT_FILE): Mention it here.
580 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
581 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
583 * lib/autotest/general.m4 (at_func_test): Remove.
584 (AT_INIT): Pre-extract test groups into separate files.
585 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
586 Remove at-test-source files together with the $at_group_dir.
587 * tests/autotest.at (Long test source lines): New test.
589 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
591 Shell functions and variables may share a namespace.
592 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
593 limitation.
595 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
597 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
598 gnulib.
600 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
602 * lib/autoconf/status.m4: Fix a couple of comment typos.
604 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
606 2007-11-13 Jim Meyering <meyering@redhat.com>
608 Clean up the rule to create "expr".
609 * tests/Makefile.am (expr): Don't redirect directly to target.
610 Redirect just once, not for each echo statement.
611 Use $@, not literal "expr".
613 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
615 Don't worry about preprocessor when testing long long.
616 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
617 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
618 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
619 These no longer check for preprocessor flaws.
620 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
621 Do not check for preprocessor flaws.
623 2007-11-13 Jim Meyering <meyering@redhat.com>
625 Adapt dependencies, now that a version change doesn't modify configure.ac
626 * GNUmakefile: Remove "make clean" kludge.
627 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
628 configure.ac.
629 Don't redirect directly to target.
630 Use $@, not literal "version.m4".
632 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
634 * doc/autoconf.texi (Making testsuite Scripts): Document
635 ":;{" shorthand as in previous patch.
637 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
639 * doc/autoconf.texi (Limitations of Builtins): Document problem
640 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
641 for the workaround.
642 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
643 Use ":;{" shorthand.
644 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
646 2007-11-12 Jim Meyering <meyering@redhat.com>
648 Add more non-srcdir build support.
649 * GNUmakefile (dummy): Split a long line.
650 Add -v option to autoreconf invocation.
652 Remove the autoreconf-provided INSTALL, so that we regenerate it.
653 * GNUmakefile (dummy): Remove INSTALL.
655 Remove racy commands to build scripts in bin/ and tests/.
656 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
657 are guaranteed to be built, remove the rules that tried to build
658 them. Before, with a parallel build, these rules could lead to
659 two processes writing tests/wrapper.in concurrently.
661 Build in man/ only *after* building in bin/ and tests/.
662 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
663 in both bin/ and tests/.
665 Accommodate non-srcdir build-from-checkout.
666 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
667 Use git's --git-dir=$srcdir/.git option.
668 Add quotes, in case tarball_version_file contains shell meta-characters.
669 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
670 * configure.ac: Pass "." to git-version-gen.
672 Avoid spurious test failures due to version skew.
673 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
675 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

678 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
679 Remove conftest.dSYM directory.
680 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
681 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
682 Remove `conftest.*' recursively.

690 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
692 Fix typos in variable names.
693 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
695 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
697 Document that $((expression)) is not portable.
698 * doc/autoconf.texi (Shell Substitutions): Here.
700 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
702 Ignore configure --help* errors due to LINENO-impaired shells.
703 * tests/torture.at (Configuring subdirectories, Deep Package):
704 In the --help* tests in read-only trees, make `.' temporarily
705 writable again for the `stderr' file, and ignore errors due to
706 the attempt to write configure.lineno.
707 Report by Patrick Welche.
709 2007-11-10 Jim Meyering <meyering@redhat.com>
711 Generate package.m4 in build-dir, not srcdir.
712 * tests/Makefile.am (package.m4): Adjust target.
713 Don't redirect directly to $@.
714 (CLEANFILES): Add package.m4.
715 ($(TESTSUITE)): Depend on just-built package.m4, not the one
716 in $(srcdir).
717 When running $(AUTOTEST), search "." before searching $(srcdir).
719 Avoid a race condition that would make parallel "distclean" fail.
720 * tests/Makefile.am (distclean-generic): Replace the default,
721 automake-provided rule with an identical one, but with an additional
722 dependency on distclean-local. Simply adding the dependency would
723 cause automake not to emit the rule at all.
724 * BUGS: Building with -jN works, now.
726 Distribute git-version-gen.
727 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
728 since GNUmakefile is distributed, and requires it for dist* rules.
730 Remove two more generated files from version control.
731 * INSTALL: Remove generated file.
732 * lib/autoscan/autoscan.list: Remove generated file.
734 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
736 * GNUmakefile (PATH): Remove stray apostrophes; they become
737 part of PATH, which isn't wanted here.
739 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
741 New config files output variable `top_build_prefix'.
742 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
743 `top_build_prefix'.
744 * doc/autoconf.texi (Preset Output Variables): Document it.
745 * NEWS: Update.
746 Report by Bob Friesenhahn.
748 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
749 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
750 function, to parametrize arithmetic with expr vs. the shell.
751 Use it where possible.
752 Suggestion by Benoit Sigoure.
754 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
756 Adjust the documentation of autotest WRT atlocal.
757 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
758 when using Automake, to write a rule to produce atlocal, since it's
759 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
760 distributed, not atconfig.in.
762 2007-11-04 Eric Blake <ebb9@byu.net>
764 Update list information.
765 * README: Mention new autoconf-commit list.
766 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
768 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
770 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
772 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
774 * build-aux/.gitignore: Ignore mkinstalldirs.
776 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
778 2007-11-03 Jim Meyering <meyering@redhat.com>
780 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
781 * build-aux/git-version-gen: This syncs from coreutils.
783 Adjust the build procedure so "make check" works reliably.
784 * README-hacking: Include an extra step between "make" and
785 "make check" to ensure that the latter passes.
787 Use just-built tools, when possible.
788 * GNUmakefile (PATH): Set and export here, ...
789 (dummy): ... rather than here.
791 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
792 and Andreas Schwab <schwab@suse.de>
794 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
795 exit status bug.
797 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
799 * configure.ac (AC_PREREQ): Require version 2.60, for
800 AC_PROG_SED, AC_PROG_GREP.
802 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
803 and Jim Meyering <meyering@redhat.com>

807 Document a bug in GNU Bash with compound commands and redirections.
808 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
809 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
810 workaround.
812 2007-11-03 Eric Blake <ebb9@byu.net>
814 Support m4 1.4.5 in testsuite.
815 * tests/torture.at (Define a newline): Exclude line numbers in
816 error message.
817 Reported by Ralf Wildenhues.
819 2007-11-03 Jim Meyering <meyering@redhat.com>
821 Remove automake-provided files from version control.
822 * build-aux/elisp-comp: Remove file.
823 * build-aux/install-sh: Remove file.
824 * build-aux/missing: Remove file.
825 * build-aux/mdate-sh: Remove file.
826 * build-aux/.gitignore: New file.
827 Suggestion from Ralf Wildenhues.
829 2007-11-03 Eric Blake <ebb9@byu.net>
831 Adjust version comparison to account for git snapshot numbers.

836 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
838 2007-10-30 Bruno Haible <bruno@clisp.org>
840 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
841 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
842 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
843 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
844 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
845 Suggested by Paul Eggert.
847 2007-10-28 Jim Meyering <meyering@redhat.com>
849 * README-hacking: Autoconf, Automake, and Perl are required to build.
850 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
852 2007-10-28 Jim Meyering <meyering@redhat.com>
854 README-hacking: Recommend running autoreconf -vi.
855 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
856 so that we use just-built tools when they're available.
857 Suggestions from Ralf Wildenhues.
859 2007-10-28 Jim Meyering <meyering@redhat.com>
861 Make inter-release --version output more useful.
863 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
864 which indicates that it is built using the 19th change set
865 (in _some_ repository) following the "v2.61a" tag, and that 58dd
866 is a prefix of the commit SHA1.
867 * build-aux/git-version-gen: New file.
868 * configure.ac: Run it to set the version.
869 (AM_INIT_AUTOMAKE): Don't check NEWS here.
870 * Makefile.am (dist-hook): Arrange so that .version appears only
871 in distribution tarballs, never in a checked-out repository.
872 * .gitignore: Add .version here, too. Just in case.
873 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
874 not configure.ac, now that the version number changes automatically.
876 Ensure that $(VERSION) is up to date for dist-related targets.
877 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
878 git-version-gen doesn't match $(VERSION), but only for dist targets.
880 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
882 Fix `Deep Package' failure with a configure script early in PATH
883 * tests/torture.at (Deep Package): Add `.' early in PATH.

908 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
909 and Eric Blake <ebb9@byu.net>
911 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
912 problem reported by Bruno Haible in
913 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
915 2007-10-22 Eric Blake <ebb9@byu.net>
917 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
918 preprocessor.
920 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
922 Don't check for bug in HP-UX 11.00 cpp.
923 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
924 Use -1ull rather than -1u, since that causes problems with gnulib; see
925 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

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

947 unnecessarily. Do not try running `/bin/sh configure' with a
948 configure script to be found in $PATH, if the shell does not do
949 this resolution. Fixes test failure on FreeBSD.
951 Fix config header generation with AIX awk.
952 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
953 script, use helper array D_is_set, as `" 0"' does not evaluate
954 to true for AIX awk.

995 array of banner text from a special diversion.
996 <PARSE_ARGS_END>: No longer need awk to find banners.
997 <TESTS>: Banners are no longer processed by main driver loop, so
998 we no longer need case statement.
999 (AT_BANNER): Rewrite to populate new diversion.
1000 (AT_SETUP): Each test invokes its own banner. No output is needed
1001 to the TESTS diversion.

2134 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

2154 for C++; this drops support for anonymous struct and union types,
2155 which were problematic anyway.

2174 with objects too. Document the restrictions on its use.
2175 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2176 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2177 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2178 works but the latter doesn't, then it's a valid type.
2179 This lets people use function types and so forth.
2180 For C++ there doesn't seem to be a simple solution, so leave it alone.
2181 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2182 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2183 AC_CHECK_TYPE; that wasn't documented or necessary.

2240 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
2241 (Limitations of Usual Tools): Also list \< and \>, and mention that
2242 HP-UX's grep, like the one from Solaris, does not support that syntax.
2244 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2246 * doc/autoconf.texi (Specifying Names): `--host' does not

2353 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2354 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2355 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2356 substitution will still be done by the special code.
2357 Report by Jim Meyering.

2425 you convert an out-of-range value to a signed integer type, and
2426 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2427 a + b.
2429 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2430 rewrite, taking notions from the recent discussion on the gcc and
2431 autoconf mailing lists; please see
2432 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2433 and follow the many links.
2434 (Integer Overflow Basics, Signed Overflow Examples):
2435 (Optimization and Wraparound, Signed Overflow Advice):
2436 (Signed Integer Division): New sections.
2438 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2440 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2441 preprocessor macro arguments in traced name.
2442 * doc/autoconf.texi (Defining symbols): Document longstanding
2443 support for AC_DEFINE-ing macros with arguments, and document
2444 behavior when the same variable has multiple AC_DEFINEs.
2445 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2446 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2447 macros directly, giving much shorter and simpler code.
2449 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2451 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2452 space before "$ac_configure_args" to prevent a 'config.status
2453 --recheck' failure if ac_configure_args doesn't contain a leading
2454 space. This works around a problem with the XEmacs configure.ac,
2455 which uses the (undocumented) ac_configure_args variable
2456 inconsistently with Autoconf.
2458 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2460 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2461 Include <limits.h>, and use its INT_MAX to rewrite the
2462 j loop so that it does not overflow 'int'. Problem reported by
2463 Ralf Wildenhues in
2464 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2465 Play it safe by shifting left by 1 rather than multiplying by 2,
2466 as GCC is less likely to optimize this away when the value
2467 is signed (when it assumes overflow leads to undefined behavior).
2468 Also, don't assume time_t uses two's complement.
2470 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2472 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2473 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2474 dumps core on it. Report by Tim Rice.
2476 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2478 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2479 --disable-option-checking to --help output even when
2480 AC_PRESERVE_HELP_ORDER is not used.
2481 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2482 --with argument, rather than argument with [-.] replaced by
2483 underscores.
2484 * NEWS: Fix typo in previous change; the news was in the
2485 wrong section.
2487 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2489 * NEWS: Warnings are now generated by default for unknown
2490 --enable-* and --with-* options.
2491 * doc/autoconf.texi (Option Checking): Renamed from
2492 (Configure Option Checking). Tighten up the wording a bit.
2493 (External Software, Package Options): Cross-reference to Option
2494 Checking, and use this to shorten our section.
2495 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2496 "$x" to test "x$foo" != x.
2497 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2498 Don't warn if $enable_option_checking is "no".
2499 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2500 ac_unrecognized_opts to the empty string.
2501 Don't echo the unrecognized opts, as this might mishandle
2502 backslashes or leading -.
2503 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2504 usage next to the other --disable-FEATURE options in the
2505 help string.
2507 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2509 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2510 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2511 Print warning for unrecognized --with and --enable options
2512 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2513 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2514 Disable option checking when subdirs are configured.
2515 (AC_OUTPUT): If warnings are enabled, print warning about
2516 unrecognized --with and --enable options at the end of
2517 the configure output (as well as at the beginning).
2518 * doc/autoconf.texi (Option Checking): New node.
2519 Document new option warning functionality.
2521 2006-12-16 Eric Blake <ebb9@byu.net>
2523 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2524 * NEWS: Start news for current version.
2526 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2528 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2529 Define HAVE_GETMNTENT to 1, not to the empty string.
2530 Problem originally reported by Jochen Friedrich in
2531 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2533 This change prompted by a problem report by Andrey Simonenko in
2534 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2535 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2536 object-like macros only, in the traditional portable character
2537 set.
2538 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2539 Warn about attempts to define things that are not identifiers.
2540 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2541 awful hack that AC_DEFINEd macro names containing parentheses.
2543 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2545 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2546 too drastic, even if Texinfo in theory requires it for info mode.
2548 (config.status Invocation): Renamed back from Recreating a
2549 Configuration).
2550 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2551 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2553 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2555 * NEWS: Version 2.61a.
2557 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2558 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2560 * NEWS: Document changes with echo and printf, and the lack
2561 of limits on the total size of multi-line values of substituted
2562 variables, and the AC_FUNC_FSEEKO fix.
2564 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2566 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2567 Writing configure.ac.
2568 (Autoconf Input Layout): Renamed from configure.ac Layout.
2569 (Recreating a Configuration): Renamed from config.status Invocation.
2570 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2571 (acconfig Header): Renamed from acconfig.h.
2572 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2573 (Writing Testsuites): Renamed from Writing testsuite.at.
2574 (Autom4te Cache): Renamed from autom4te.cache.
2576 * BUGS: Remove mention of VPATH problem, since it's now documented
2577 not to be a bug in the Autoconf build procedure itself, but rather
2578 a problem with the proprietary `make' programs.
2580 * doc/autoconf.texi (Build Directories): Add a cross reference
2581 to VPATH and Make.
2583 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2584 * doc/standards.texi: Sync from gnulib.
2586 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2587 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2588 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2589 generated automatically.
2591 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2593 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2594 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2595 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2597 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2599 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2600 `CEOF$ac_eof' special marker, the awk script cannot contain a
2601 line matching `^CEOF', so this is not needed any more.
2602 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2603 special marker in the test.
2605 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2607 * tests/tools.at (autom4te preselections): Use `find -newer';
2608 remove one of the sleeps.
2610 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2611 more readable, using ...
2612 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2614 * doc/autoconf.texi (autoheader Invocation): Do not double-
2615 quote the parameter of `AH_BOTTOM' in the example.
2617 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2619 * doc/autoconf.texi (Configuration Headers): Remove the
2620 example with multiple input files.
2621 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2622 multiple input files.
2624 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2627 creating the awk substitution script, handle one input line at a
2628 time, so that the maximum length of a substituted (multi-line)
2629 value is not limited by the size of the sed pattern space.
2630 The trade-off is a slightly repetitive sed script.
2631 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2632 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2633 * tests/torture.at (Substitute a 2000-byte string): Increase the
2634 test with several long lines, they should not be caught by sed
2635 limits any more.
2637 * tests/tools.at (autom4te preselections): New test, to flag
2638 entries missing from autom4te.cfg.
2639 Report by David Byron <dbyron@hheld.com>.
2641 * tests/torture.at (Substitute a 2000-byte string): Actually use
2642 AC_PROG_AWK, so the last change works as intended.
2643 (Substitute and define special characters): Likewise.
2644 (Substitute a newline): Likewise.
2646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2647 instead of `awk' consistently.
2648 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2649 * tests/torture.at (Torturing config.status): Test both the
2650 result of AC_PROG_AWK and plain awk.
2651 (Substitute a 2000-byte string): Likewise.
2652 (Substitute and define special characters): Likewise.
2653 (Substitute a newline): Likewise.
2655 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2657 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2658 can be assigned to a function pointer. Problem reported by
2659 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2660 part of a patch by Ralf Wildenhues in that same bug report.
2662 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2664 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2665 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2667 2006-12-01 Eric Blake <ebb9@byu.net>
2669 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2670 cross-compiling from cygwin to mingw.
2671 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2672 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2673 to lib/autoconf/c.m4.
2675 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2677 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2678 string for more reliable failure. Wrap the entire test that
2679 causes the broken Solaris printf to dump core, in a subshell,
2680 so the segmentation fault message is reliably suppressed.
2681 Fix shell expansion errors by using /usr/ucb/echo always;
2682 avoid an error on systems without it by another subshell.
2683 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2684 subshell-$as_echo to `as_echo', for better error message.
2686 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2688 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2689 `BASH_SOURCE' contain a newline, set them to empty, as they may
2690 not be unset.
2692 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2694 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2695 years and is too hard to maintain now. The last straw was
2696 reported by Jerker Baeck in
2697 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2698 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2699 * doc/autoconf.texi (Particular Functions): Move
2700 AC_FUNC_SETVBUF_REVERSED from here...
2701 (Obsolete Macros): ... to here. Say that it does nothing now.
2702 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2703 Turn into (almost) a no-op.
2705 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2706 (AC_C_VOLATILE):
2707 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2708 These macros are obsolescent and new applications shouldn't need them.
2709 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2710 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2711 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2712 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2713 (AC_FUNC_VPRINTF): Likewise.
2714 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2715 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2716 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2718 * doc/autoconf.texi (Setting Output Variables): Mention that
2719 @VAR1@VAR2 has unspecified behavior. Problem reported by
2720 Ralf Wildenhues.
2721 * NEWS: Mention this.
2723 * Makefile.am: Put only a single '#' into the copyright notice,
2724 so that it's also present in the output file. Standardize wording
2725 in makefile copyright notices to match GNU coding standards.
2726 * bin/Makefile.am: Likewise.
2727 * doc/Makefile.am: Likewise.
2728 * lib/Makefile.am: Likewise.
2729 * lib/freeze.mk: Likewise.
2730 * lib/autoconf/Makefile.am: Likewise.
2731 * lib/autoscan/Makefile.am: Likewise.
2732 * lib/autotest/Makefile.am: Likewise.
2733 * lib/m4sugar/Makefile.am: Likewise.
2734 * man/Makefile.am: Likewise.
2735 * tests/Makefile.am: Likewise.
2736 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2737 one-line file.
2739 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2741 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2742 in the sed script that mangles the awk script: delete up to the
2743 first exclamation mark only.
2744 * tests/torture.at (Substitute and define special characters):
2745 Test '!' too.
2747 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2749 Rewrite config files generation: avoid quadratic growth in
2750 the number of substituted variables by using awk instead of sed
2751 for the bulk of the substitutions.
2752 * NEWS: Mention this.
2753 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2754 forbidden in the output (and thus input) file.
2755 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2756 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2757 generate just one large awk script for substitutions,
2758 eliminating much of the earlier complexity, while adding some
2759 new complexity. Only expand the substitution templates at
2760 configure time, for smaller configure script size. If
2761 _AC_SUBST_FILES are used, test 'awk' for working getline support
2762 at config.status time. If absent, interpolate through the
2763 shell. The awk script was written with much help
2764 from Paolo Bonzini and Paul Eggert.
2765 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2766 (_AC_SED_FRAG_NUM): Likewise.
2767 (_AC_SUBST_CMDS): Renamed from...
2768 (_AC_SED_CMDS): ...this.
2769 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2770 * tests/torture.at (Substitute a 2000-byte string): Also
2771 substitute a line with 1000 words, and a variable with several
2772 long lines.
2773 (Substitute and define special characters): Test awk special
2774 characters, and put substitution input strings `@foo@' in the
2775 output, to test that no recursion happens; test several other
2776 combinations from Paolo Bonzini.
2778 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2780 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2781 that replaced echo with AS_ECHO where this wasn't necessary.
2782 Problem reportd by Ralf Wildenhues.
2783 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2784 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2785 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2787 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2789 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2791 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2793 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2794 that traditional Awk lacks 3-arg "split". It has it.
2795 Mention that FS must be a single character, and a few other
2796 99-byte limits of traditional Awk.
2797 Mention that if (i in a) doesn't work with traditional Awk.
2799 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2801 * tests/autotest.at (BSx641-newline in command):
2802 (BS-BS-newline in command, BSx640-newline in command):
2803 (Newline-CODE-BS-newline in command):
2804 (Single-quote-BS-newline in command):
2805 (Single-quote-newline-BS-newline in command):
2806 Use printf '%s\n' instead of echo, for portability to hosts
2807 where echo interprets backslashes. This will break on hosts
2808 that lack printf, but for now let's assume all such hosts
2809 are dead (if not, we should get reports of test failures).
2811 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2813 'echo' has some portability problems, when given a first argument
2814 with a leading '-', or when given any argument containing '\'.
2815 Avoid using 'echo' in these cases.
2816 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2817 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

2819 * lib/autotest/general.m4 (AT_INIT): Likewise.
2820 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2821 argument might be unportable.

2823 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

2825 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
2826 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
2827 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):

2840 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2841 * bin/autoconf.as: Redo verbose flag implementation, as the old
2842 scheme wouldn't work with AS_ECHO.
2843 * lib/autotest/general.m4 (AT_INIT): Likewise.
2844 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2845 Don't use ECHO_T, since ECHO_N is now reliable.
2846 * lib/autotest/general.m4 (AT_INIT): Likewise.
2847 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2848 rather than using a here-document to put the script into a file.
2849 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2850 use AS_ECHO.
2851 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2852 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2853 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2854 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2855 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2856 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2857 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2858 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2859 operand, as AS_ECHO requires. Avoid double file name expansion.
2860 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2861 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

2863 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

2868 * configure.ac (AC_INIT): Bump to 2.61a.
2869 * NEWS: Likewise.
2871 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>

2875 * configure.ac (AC_INIT): Bump to 2.61.
2876 * NEWS: Likewise.
2878 * tests/autotest.at (Macro with backslash in a test title):
2879 Comment out for now, as this tests neither fails nor passes
2880 reliably. Problem reported by Ralf Wildenhues.
2882 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2884 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2885 in previous change, which caused test failures.
2887 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2889 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2890 code for --enable, --disable, --with, and --without to...
2891 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2892 * doc/autoconf.texi (Package Options):
2893 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2895 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

2926 * standards.texi: core -> memory, throughout.
2927 (CPU Portability): show correct example of calling write

2929 Both of these suggestions from Eugene Y. Vasserman.
2932 Import these changes from texinfo via gnulib:
2934 2006-11-08 Karl Berry <karl@gnu.org>
2936 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
2937 as well as pdf images, since they are supported in pdftex with
2938 no further ado.
2940 2006-11-05 Karl Berry <karl@gnu.org>
2942 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

2946 * NEWS: Document the AC_ARG_WITH change.
2948 2006-11-13 Bruno Haible <bruno@clisp.org>

2956 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
2958 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
2959 benefit of platforms like Solaris+GCC where it is common to have a
2960 non-working g++ installation.
2962 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2963 and Joel E. Denny <jdenny@ces.clemson.edu>
2964 and Paul Eggert <eggert@cs.ucla.edu>

2970 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2972 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2973 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2974 Imported from a similar patch to gnulib by Bruno Haible.
2976 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2978 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
2979 * doc/autoconf.texi (C Compiler): Document them.
2980 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
2981 New macros, taken from gnulib.
2983 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

2991 * tests/torture.at (Configuring subdirectories): Do not skip
2992 Automake 1.10 nor future Automake 11.1 (sic).
2994 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2995 and Stepan Kasal <kasal@ucw.cz>
2997 Handle special characters in test case titles correctly.

3003 ./micro-suite -l and the title in micro-suite.log.
3004 (Backquote in a test title,
3005 Single-quote in a test title,
3006 Double-quote in a test title): Don't expect failure anymore.
3007 (Backslash in a test title): Put a non-whitespace character after the
3008 backslash so that Bourne shells might actually see it as an escape
3009 sequence.
3010 (Brackets in a test title,
3011 Pound in a test title,
3012 Comma in a test title,
3013 Quoted Macro in a test title,
3014 Macro in a test title,

3016 (Macro with backquote in a test title,
3017 Macro with double-quote in a test title,
3018 Macro with backslash in a test title): New tests expected to fail.
3019 * tests/torture.at (#define header templates): M4-quote this title in
3020 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3021 The visible effect was a stray [] in the testsuite output.
3023 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3025 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3026 `trap ... 0' inside a function, for AIX sh.
3028 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3030 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3031 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3032 5363) simply issues a warning when dividing by zero at compile
3033 time. Problem reported by Elias Pipping.
3035 2006-10-26 Eric Blake <ebb9@byu.net>
3037 * THANKS: Update.
3038 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3039 show effect on macros that expand with commas.
3040 Reported by Joel E. Denny.
3042 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3043 Also work with M4 1.4.8.

3047 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
3048 Jim Meyering.
3050 2006-10-25 Stepan Kasal <kasal@ucw.cz>

3055 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3057 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

3064 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3066 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3067 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3068 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3069 reported by Nelson H. F. Beebe for Coreutils 6.4.
3071 * tests/tools.at (autoconf --trace: user macros): Remove test
3072 for tracing multiline macros, since m4 1.4.7a uses a different
3073 way to number lines. Problem reported by Ralf Wildenhues.
3075 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3077 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3078 /dev/null since the heuristics for interactive behaviour was
3079 fixed in CVS m4.
3081 * bin/autom4te.in: With --force, always refresh the output
3082 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3084 * bin/autoconf.as: Fix the verbose message at the end.
3086 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3099 * NEWS: Remove AC_CACHE_CHECK_INT.
3100 * doc/autoconf.texi (Caching Results): Likewise.

3102 AC_CACHE_CHECK_INT, since it's no longer public.
3103 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3104 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3106 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3108 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
3110 2006-10-19 Eric Blake <ebb9@byu.net>
3112 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
3113 (m4_maketemp): Avoid warnings with M4 1.9a.

3115 m4_mkstemp.
3116 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

3132 2006-10-14 Stepan Kasal <kasal@ucw.cz>
3134 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
3135 looking for special shell characters.
3136 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3137 macro defined by AS_VAR_PUSHDEF before passing it as a
3138 parameter.
3139 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
3140 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

3149 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3151 (Imported from Automake.)
3152 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3153 which incorrectly sets the mode of an existing destination
3154 directory. In some cases the unpatched install-sh could do the
3155 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3156 system. We hope this is rare in practice, but it's clearly worth
3157 fixing. Problem reported by Alex Unleashed in
3158 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3159 Also, don't bother to check for -m bugs unless we're using -m;
3160 suggested by Stepan Kasal.
3162 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3164 Import this change from Automake:
3166 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
3167 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
3168 is enabled by default with gnu and gnits strictness.
3169 Report from Bruno Haible.
3171 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
3172 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
3173 gnu and gnits modes.
3175 Import this change from Config:
3177 2006-09-20 Ben Elliston <bje@gnu.org>
3178 * build-aux/config.sub (score, score-*): New.
3180 Import this change from Gnulib:
3182 2006-09-16 Karl Berry <karl@gnu.org>
3183 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
3184 to avoid sectioning errors.
3186 Import these changes from Texinfo:
3188 2006-10-04 Karl Berry <karl@gnu.org>
3189 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
3190 (\quoteexpand): rename to \rquoteexpand.
3191 (\codequoteleft): new def, to look for @set codequotebacktick.
3192 (\lquoteexpand, \quoteexpand): new defs.
3193 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
3194 (\code): must use new \...Char values, since now ` is active.
3196 2006-08-26 Karl Berry <karl@gnu.org>
3197 * build-aux/texinfo.tex (\textdegree): New command.
3199 2006-08-12 Karl Berry <karl@gnu.org>
3200 * build-aux/texinfo.tex (error \box0): smaller font.
3202 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3204 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
3206 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3208 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3209 added to the template can get mangled.
3211 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3213 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3214 include the default headers, and redefine obstack_chunk_alloc
3215 and obstack_chunk_free. Fixes false failure with glibc.
3217 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3219 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
3220 for backward compatibility with Libtool 1.5.22. Problem reported
3221 by Ralf Wildenhues.
3223 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3225 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
3226 AC_PROG_CC.
3227 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
3229 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3231 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
3232 the NonStop platform.
3233 * doc/autoconf.texi (Posix Variants): Likewise.
3234 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3236 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3237 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3238 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3239 Use a better substitute, by inspecting the output of "ls"
3240 rather than just using ":".
3241 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3242 rather than AS_EXECUTABLE_P, since we needn't worry about
3243 non-regular files here.
3245 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3246 due to configuration hassles with this. See Tonya Underwood's report
3247 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
3248 * doc/autoconf.texi (Special Shell Variables): Likewise.
3250 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3251 Stepan Kasal <kasal@ucw.cz>
3253 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
3254 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
3256 2006-10-11 Stepan Kasal <kasal@ucw.cz>
3258 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3259 initialization which is not inherited through the environment
3260 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3261 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
3263 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3265 * doc/autoconf.texi (Limitations of Usual Tools): Describe
3266 problems with mkdir -p -m.
3268 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3270 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3271 comment about ac_cpp_err; it was incorrect, and anyway
3272 ac_cpp_err is being removed below.
3273 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3274 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3275 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3276 nobody uses it.
3277 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3278 with werror_flag and conftest.err and so forth. This is more
3279 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3280 and anyway the user shouldn't normally want to see this gorp logged.
3281 Problem reported by Ralf Wildenhues.
3282 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3283 empty, not 'no', since the rest of the code uses 'test -z'.
3285 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3287 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3288 Use a single call to AC_DO_TOKENS rather than multiple, for
3289 efficiency.
3290 (_AC_LINK_IFELSE): Test that resulting file is executable.
3291 Problem reported by mwoehlke in
3292 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3294 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3295 than creating a file to use with test -x; this is much faster.
3297 2006-10-02 Bruno Haible <bruno@clisp.org>
3299 * lib/autom4te.in (Automake-preselections): Add
3300 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3302 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3304 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3305 standard error, `experr' should be used, not `expout'.
3307 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
3309 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3310 fseeko testing program twice; just use the earlier result.
3311 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3312 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3313 still doesn't let the program compile.
3314 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3315 failed.
3317 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3318 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

3447 to catch glibc bug 2821
3448 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
3450 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
3451 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
3452 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
3453 assume C89.

3475 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

3551 deal with LEXLIB.
3552 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
3553 didn't work if some values were cached but not others. Test for
3554 broken lex libraries like native ia64-hp-hpux11.22; see
3555 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
3556 work around the problem by preferring an empty LEXLIB to -lfl or
3557 -ll. Let the user set LEXLIB='' to indicate no library needed.
3559 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
3560 * README: Likewise.

3755 complaint. Problem reported by Peter O'Gorman.
3757 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3758 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3759 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3761 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3763 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3764 after -R regardless of host. Patrick Welche reports that this
3765 fixes things on NetBSD 3.99.
3767 * NEWS: Recommend M4 1.4.5.
3768 * README: Likewise.
3769 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
3770 * tests/tools.at (autom4te cache): Update wording of diagnostic
3771 to match M4 1.4.5.
3773 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3775 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3776 under AC_C_VOLATILE.
3777 (Volatile Objects): Be a little less skeptical about what
3778 "volatile" means. Derived from thoughts by Ben Pfaff in
3779 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3781 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3783 * doc/autoconf.texi: Fix some typos.
3785 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3787 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3788 more globally, since the 2006-06-30 patch didn't suffice. Problem
3789 reported by Keith Marshall. Also, don't bother with builddir2,
3790 since it shouldn't be needed any more.
3792 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3794 * doc/autoconf.texi (Generic compiler characteristics):
3795 Document AC_COMPUTE_INT. Fix wrong statements on Default
3796 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
3798 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
3799 (_AC_COMPUTE_INT): Add obsoletion warnings.
3800 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
3801 AC_COMPUTE_INT.
3803 * NEWS: Document change.
3805 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
3807 * doc/autoconf.texi (Volatile Objects): New section.
3809 * NEWS: Document previous change.
3811 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3813 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3814 Require that long long int be at least 64 bits wide. C99 requires
3815 this and enough programs depend on it so we should check for it.
3816 Bruno Haible reports in
3817 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3818 that long long int is 32 bits wide with some nonstandard compilers.
3819 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3821 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3823 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3824 to a nonexistent file, so that we don't have to worry about
3825 a local site configuration that doesn't use /usr/local.
3826 Problem reported by Keith Marshall in
3827 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3829 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3831 * doc/autoconf.texi: Be more consistent about using @acronym with
3832 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3833 quite right (it talked about "OSF/Tru64", even though the
3834 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3835 and it even mentioned "OSF 4"!) and at this point there's little
3836 reason to talk about OSF any more, since it died in 1994.
3837 (Specific Compiler Characteristics): Simplify example of
3838 negative-size array.
3839 (File Descriptors): Reorder to make the text flow better.
3840 Remove joke about "appreciate the various levels"; I didn't get it.
3841 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3842 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3843 (File Descriptors, Limitations of Usual Tools):
3844 Tone down the advice against renaming or removing open files.
3845 (Limitations of Usual Tools): Add a new section, on 'rm'.
3847 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3849 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3850 -lXt in LIBS, idea from Karsten Hopp; this was due since
3851 this change:
3853 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3854 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3855 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3856 (which belong to Xt, not X itself). See Debian bug 327655.
3858 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3860 * configure.ac (AC_INIT): Bump to 2.60a.
3861 * NEWS: Update.
3863 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3865 Version 2.60.
3867 * configure.ac, NEWS: Update.
3869 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3871 * config/texinfo.tex: Sync from upstream.
3873 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3874 quadrigraph correctly in traces.
3876 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3877 Fix typos.
3879 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3880 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3881 not defined.
3882 * doc/autoconf.texi (Changed Directory Variables): New node,
3883 to document the whole `datarootdir' business a bit better.
3884 * NEWS: Update.
3885 * tests/torture.at (datarootdir workaround): Extend test.
3886 Prompted by report by Alexandre Julliard.
3888 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3890 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3891 when using default mode of IBM C 6 for AIX. Problem and two-line
3892 fix reported by Larry Jones.
3894 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3896 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3897 about literal '${datarootdir}' if a definition is found in the
3898 output file.
3900 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3902 * NEWS: Use "M4" rather than "m4" when appropriate.
3903 Problem reported by Eric Blake.
3904 * doc/autoconf.texi: Likewise.
3905 Use @acronym around BSD, GCC, and GNU when appropriate.
3906 (Why GNU M4): Renamed from "Why GNU m4".
3907 (Redefined M4 Macros): Mention that Posix
3908 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3909 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3910 to int.
3912 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3914 * bin/autom4te.in (handle_output): Do not forbid the empty
3915 pattern.
3916 * tests/tools.at (autoconf: the empty token): New test.
3918 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3920 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3921 calls, so that we do not care whether they are LIFO or FIFO;
3922 in the m4_wrap, do not check which diversion is the topmost
3923 one, just check that the stack is balanced at the end.
3924 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3925 base diversion forever--pop the previous diversion before
3926 opening the new one; consequently, remove the m4_wrap call.
3927 * lib/autotest/general.m4 (AT_INIT): Likewise.
3928 * tests/m4sugar.at: Do not use
3929 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3931 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3932 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3934 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3935 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3936 Rework example of m4wrap token-pasting trouble so that it doesn't
3937 care whether it's LIFO or FIFO.
3938 Fix some "contrary to"s that are awkward in English.
3940 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3942 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3943 to `yes' instead of `int$1_t' if the type is found, for more
3944 consistent configure output (where $1 is the number of bits).
3945 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3946 Suggested by Bruno Haible.
3948 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3949 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3950 with system headers. Report by Bruno Haible.
3952 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3954 * config/config.guess, config/config.sub: Sync from upstream.
3956 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3957 in order to avoid picking up an older installed frozen m4sh.m4f.
3958 Besides an outdated shell startup, this could have been created
3959 by an earlier M4 version with incompatible frozen file format.
3961 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3963 * README: Recommend m4 1.4.4 instead of 1.4.3..
3964 * doc/autoconf.texi: Likewise.
3965 (Special Chars in Names): Say that $(.FOO) is portable, as
3966 suggested by Stepan Kasal.
3967 (Installation Directory Variables, Build Directories):
3968 (Automatic Remaking, Subdirectories, Fortran Compiler):
3969 (Making testsuite Scripts, Defining Directories):
3970 Quote variable usages better.
3971 (Making testsuite Scripts): Add clean-local rule to makefile
3972 snippet, by Eric Blake.
3973 (Installation Directory Variables): Fix table item font.
3974 Reword slightly to clarify. Generalize advice about
3975 not using special characters to include all file-related
3976 vars, not just VPATH.
3977 (Special Chars in Variables): Warn about special characters in
3978 $(srcdir) too.
3979 (Assignments): Clarify default-value example as suggested by
3980 Ralf Wildenhues in
3981 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3982 (Special Shell Variables): Note leading ./ or ../, as suggested
3983 by Eric Blake.
3984 (Limitations of Builtins): Under cd, warn about CDPATH.
3985 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3986 Ralf Wildenhues.
3988 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3990 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3991 `@var', for texi2html.
3992 (Systemology): Some more word wrapping, for DVI output.
3993 (autom4te Invocation): The short option for `--melt' is `-M',
3994 not `-m'.
3996 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3998 * doc/autoconf.texi: More formatting and English tweaks,
3999 many suggested by Ralf Wildenhues.
4000 Reword to avoid "@code{...}'s" and the like, since it's ugly
4001 with Emacs info mode. discontents -> woes.
4002 Put a few "will"s back. time stamp -> timestamp.
4003 side-effect -> side effect.
4005 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4007 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4008 Warn about $@ not persisting. Problem reported by Julien Danjou in
4009 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4010 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4011 Mention other special chars, too.
4013 2006-06-14 Eric Blake <ebb9@byu.net>
4015 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4017 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4019 * doc/autoconf.texi: Some systematic minor improvements, as
4020 follows. Use "makefile" when talking about makefiles
4021 generally (which might be named "makefile" or "Makefile" or even
4022 "foo.mk"), "Makefile" when talking about a specific makefile
4023 called "Makefile". This unclutters the text from weird quotes
4024 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4025 values" rather than "@var{foo}s" and similar constructs containing
4026 "}s". Use "Make rules" rather than "Makefile rules". Minor
4027 English-language improvements. Change the prefix "sub-" to "sub"
4028 and "re-" to "re".
4029 Put blank lines around examples more consistently.
4030 Avoid "rather" and "very" as intensifiers.
4031 Avoid "will" as an auxiliary.
4032 (Limitations of Make): Split this node into....
4033 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4034 (Leading _ in Macro Names, Backslash-Newline-Newline):
4035 (Backslash-Newline Comments, Long Lines in Makefiles):
4036 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4037 (obj/ and Make, make -k Status, VPATH and Make):
4038 (VPATH and Double-colon, $< in Explicit Rules):
4039 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4040 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4041 New nodes, resulting from splitup of Limitations of Make.
4042 All cross-references changed. Raise the top node from
4043 a section to a chapter, and all subnodes accordingly.
4044 Redo the introductory wording to match the new organization.
4045 (Installation Directory Variables): Use an example that is
4046 closer to what Autoconf actually does. Mention that VPATH's
4047 value should not contain metacharacters or white space.
4048 (Fortran Compiler): Fix a VPATH bug in an example.
4049 (Leading _ in Macro Names): Mention that this problem is no longer
4050 of practical concern.
4051 (VPATH and Make): Reword the advice to make it clearer
4052 that Autoconf and Automake support VPATH in non-GNU make, but
4053 many packages have bugs in this area.
4054 ($< in Explicit Rules): Refer to Build Directories rather
4055 than using a (non-VPATH-safe) example.
4056 (Automatic Rule Rewriting): Mention the sort of disaster that
4057 can ensue with Solaris-style rule rewriting with VPATH.
4059 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4061 * doc/install.texi (Compilers and Options): Weaken the
4062 suggestion to use GNU make for VPATH builds.
4064 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4065 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4067 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4068 in regular expression.
4070 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4072 * doc/autoconf.texi (Installation Directory Variables):
4073 Drop extra @samp from `@table @samp' item.
4074 (Limitations of Usual Tools): Comment fix.
4075 Do not nest @samp just to point to other table items.
4076 (Writing testsuite.at) <AT_CHECK>: The second argument to
4077 `@dvar' is already @samp'ed.
4078 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4079 do not use @var in the second argument.
4081 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4083 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4084 $as_shell.exe too. Problem reported by Andreas Buening in
4085 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4087 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4089 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4090 `unused variable' compiler warning, for `-Wall -Werror'.
4091 Reported by Jaap Haitsma in
4092 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4094 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4096 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4097 case the compiler dumps core. Problem reported for
4098 OpenServer 5.0.7 by Tim Rice in
4099 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4100 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4101 Likewise.
4103 2006-06-06 Tim Rice <tim@multitalents.net>.
4105 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4106 "ERROR" only shows up in "make check" output if there is an
4107 error.
4109 2006-06-06 Eric Blake <ebb9@byu.net>
4111 * tests/tools.at (automatically allowed tokens): Fix typo.
4113 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4115 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4117 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4118 typically overflows on x86 CPUs, even though the C standard
4119 requires otherwise.
4121 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4123 * configure.ac (AC_INIT): Bump to 2.59e.
4124 * NEWS: Update.
4126 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4128 Version 2.59d.
4130 * config/texinfo.tex: Sync from upstream.
4132 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4133 seen, invoke libtoolize with `--ltdl' argument.
4134 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4135 * NEWS: Update.
4136 Suggested by Eric Blake.
4138 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4140 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4141 reported by Ralf Wildenhues.
4142 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
4144 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4158 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4159 to...
4160 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4161 AT_CHECK_M4.
4162 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4163 `expout' as the last parameter.
4164 * tests/tools.at: Adapt to the above change.
4166 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4168 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4169 information about race-free implementations of mkdir.
4171 2006-06-04 Eric Blake <ebb9@byu.net>
4173 * bin/autoreconf.in (help): Document M4 environment variable.
4174 * bin/autoconf.as (Usage): Likewise.
4175 * bin/autom4te.in (help): Likewise.
4176 * doc/autoconf.texi (autom4te Invocation): Likewise.
4178 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4180 * NEWS: GNU make now recommended for VPATH builds.
4181 Mention that some macros are now documented to be obsolescent.
4182 * doc/autoconf.texi:
4183 Prefer "current" to "modern" to describe
4184 currently-used (albeit perhaps old-fashioned) hosts.
4185 Mention which ancient features no longer need to be worried about.
4186 setgid -> set-group-ID
4187 setuid -> set-user-ID (these are the Posix terms)
4188 Fix some misuses of "only".
4189 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4190 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4191 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4192 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
4193 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
4194 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
4195 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
4196 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4197 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4198 Mention that these macros are obsolescent.
4199 (Installation Directory Variables): shall -> should
4200 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4201 Mention that it's now safe to use 3 and 4.
4202 (Limitations of Usual Tools): cp -r is now specified by Posix.
4203 Omit longwinded and obsolescent discussion of cp -f.
4204 Modernize discussion of expr, ls.
4205 (Limitations of Make): Modernize discussion of VPATH builds.
4206 Mention $? as a workaround in some cases.
4207 * doc/install.texi (Basic Installation):
4208 Mention "./configure; make; make install" first. Be more
4209 specific about why this file is generic. Remove unnecessary
4210 parens. Remove misleading "only". Remove obsolete advice
4211 about csh. Don't say "configure" takes awhile; say it
4212 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4213 and CC=c99 rather than CC=c89, as these are blessed by current
4214 Posix. Recommend GNU make if doing a VPATH build.
4216 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4218 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4219 examples involving shell prompts.
4221 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4222 and Paul Eggert <eggert@cs.ucla.edu>
4224 * doc/autoconf.texi (Here-Documents): Add details about the
4225 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4226 use "here-documents" instead of "here documents".
4228 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4230 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4232 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4234 * doc/autoconf.texi (File System Conventions): Warn about ":"
4235 anywhere in directory names.
4237 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4239 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4240 about quoting the case statement, just in case.
4241 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4242 was fixed in ksh93g; reported by Ralf Wildenhues.
4244 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4246 * doc/autoconf.texi (System Services): Do not document
4247 overriding EXEEXT via ac_cv_exeext=ext.
4248 (Particular Programs) <AC_PROG_MKDIR_P>:
4249 Document that ${MKDIR_P} understands --.
4250 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
4251 comment.
4253 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4255 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4256 argument with leading hyphen. Problem reported by Paul Eggert.
4258 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4260 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4261 about quoting ac_try: quote all of it, if any of it seems suspicious.
4262 This means we don't have to worry about ${ or sed any more.
4263 Also, double-quote the case statement, to work around misuses via
4264 underquoting as reported by Ralf Wildenhues in
4265 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4266 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4267 undocumented and dangerous macro.
4268 Problem reported by Ralf Wildenhues in
4269 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4271 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4273 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4274 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
4275 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
4277 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4279 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4280 since evidently some packages rely on the old, broken behavior.
4281 Problem reported by Ralf Wildenhues in
4282 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4283 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4284 pre-2006-05-26 definitions, but leave in the comments that
4285 these macros are dangerous and should not be used.
4286 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4287 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4288 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4289 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4290 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4292 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4294 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4295 the use of 'tr', since this is our only use of 'tr'.
4297 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 and Paul Eggert <eggert@cs.ucla.edu>
4300 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4301 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4303 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4305 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4306 the output file in the `${datarootdir}' test.
4308 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4309 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4311 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4312 mention of `datarootdir' in the input file(s), but literal
4313 `${datarootdir}' in the output file, and we haven't warned yet,
4314 then warn as well: the user may have (erroneously) used
4315 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4316 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4317 * tests/torture.at (datarootdir workaround): Extend this test.
4318 * NEWS: Update.
4320 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4321 and Paul Eggert <eggert@cs.ucla.edu>
4323 * doc/autoconf.texi (autoheader Invocation): The first argument to
4324 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4325 alternatives and clear up the language a bit.
4327 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4329 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4330 ac_config_guess, ac_config_sub, ac_configure.
4331 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4332 Fix typo that prevented an unnecessary space from being removed.
4333 Problems reported by Ralf Wildenhues in:
4334 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4336 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4338 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4339 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4340 Don't use the term "thread-safe" to talk about mkdir race
4341 conditions, since the problem is more a process than a thread
4342 issue. Problem reported by Stepan Kasal in:
4343 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4344 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4345 the test for 'install' more closely. Look at MKDIR_P first.
4346 Look in the PATH, and at /opt/sfw/bin.
4347 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4348 Don't bother to try mkdir -p, since we already check mkdir --version;
4349 just look at the version number. (There's no easy way to check
4350 for race-free implementations.)
4351 * tests/tools.at (autoconf: subdirectories): Adjust to above
4352 changes, since MKDIR_P now might end in "/mkdir -p".
4354 * doc/autoconf.texi (autoheader Invocation): Mention that the
4355 first arg of AC_DEFINE_UNQUOTED must be a literal.
4356 Problem reported by Ben Pfaff in
4357 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4359 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4360 * doc/autoconf.texi (Special Chars in Variables): New section.
4361 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4362 (Installation Directory Variables): Quote $(datadir) better.
4363 (Limitations of Builtins): Describe some of eval's trickiness.
4365 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4366 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4367 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4368 in front of every arg, not just trailing args. Quote apostrophes.
4369 (_AC_EVAL_ECHO): New macro.
4370 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4371 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4372 removed.
4373 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4374 exposed by quoting of eval argument. Put the command on line line
4375 so it logs better.
4376 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4377 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4378 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4379 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4380 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4381 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4382 Use eval more safely.
4383 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4384 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4385 to be replaced.
4386 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4387 lines, exposed by quoting of eval argument.
4389 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4390 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4392 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4393 initialization of `ac_cv_exeext', do not override it if it was
4394 already set, unless it was set to `no', for compatibility with
4395 Autoconf-2.13, and comment this.
4396 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4397 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4398 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4399 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4400 Document that this test may be overridden by setting
4401 `ac_cv_exeext'.
4403 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4405 Revert these two patches:
4407 2006-04-06 Eric Blake <ebb9@byu.net>
4408 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4409 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4410 2006-04-01.
4412 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4413 Clean up _AC_COMPILER_EXEEXT* macros.
4414 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4415 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4416 ac_file to the name of the default output file and call
4417 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4418 initial `rm' of the candidate files...
4419 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4420 the same list in subsequent `rm' calls, and for the temporary
4421 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4422 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4423 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4424 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4425 no longer needed) by libtool. Make it a cache check.
4426 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4427 copied here by mistake.
4428 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4429 _AC_COMPILER_EXEEXT.
4430 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4431 _AC_COMPILER_OBJEXT directly.
4432 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4434 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4436 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4437 Fix description of how the buggy `sed' works.
4439 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4441 Sync from Automake:
4443 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4444 ENOLCK. Only mention `make -j' when applicable. Only raise
4445 fatal errors when `make -j' is involved. Improve error message.
4447 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4449 * doc/autoconf.texi (Here-Documents): We now know more about
4450 the variable expansion in here documents bug.
4451 Thanks to Tim Rice and Stepan Kasal.
4453 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4454 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4456 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4458 * tests/autotest.at (Multiline command from M4 expansion):
4459 No failure to be expected if the shell quotes newlines in
4460 commands in the `set -x' output. Report by Tim Rice.
4461 * THANKS: Update.
4463 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4465 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4466 expansion in the here-documents used by config.status, as that
4467 runs afoul of the Korn shell version M-12/28/93d bug described in
4468 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4469 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4470 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4472 2006-05-23 Jim Meyering <jim@meyering.net>
4474 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4475 Fix typo introduced with 2006-04-02 change. It reversed the sense
4476 of the test.
4478 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4480 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4481 ac_dB slightly, to save bytes in the script.
4482 Max out at 50 lines, rather than 96; this is more likely
4483 (though not guaranteed) to avoid obscure 'sed' failures.
4485 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4487 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4488 `tr -d -' as bad option argument. Work around this by deleting
4489 an unrelated character.
4490 Report by Tim Rice <tim@multitalents.net>.
4492 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4493 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4494 Stepan Kasal <kasal@ucw.cz>
4496 * doc/autoconf.texi (Particular Programs): Do not promise that
4497 we always prefer the GNU version of the program, and that we
4498 search according to PATH; both rules can have exceptions.
4499 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4500 AC_PROG_SED. Move descriptions of limitations
4501 to the Limitations of Usual Tools section.
4502 (Limitations of Usual Tools) <sed>: Mention script length
4503 limitations with Solaris /usr/ucb/sed.
4504 <grep>: Fix wording for empty alternative. Mention that -c and
4505 -l should not be combined, and that -E and -F should not be
4506 combined.
4508 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4509 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4511 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4512 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4514 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4516 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4517 AC_DEFINE is now passed to m4_pattern_allow.
4518 * NEWS: Mention that; likewise for AC_SUBST.
4519 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4520 the parameter to m4_pattern_allow.
4521 * tests/tools.at: Add a check for that.
4523 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4525 * lib/autoconf/status.m4: Fix typos.
4527 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4529 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4530 only the files that this macro generates.
4532 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4534 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4535 the HP-UX sed limitation of 99 commands, labels do not count.
4536 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4537 in the comment.
4538 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4540 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4542 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4543 Import the following fix from coreutils:
4545 2006-01-13 Jim Meyering <jim@meyering.net>
4547 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4548 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4549 not double-quote uses of that variable, to accommodate the rare
4550 case in which getmntent is available in none of the libraries
4551 checked. This happens at least on FreeBSD 5.0.
4553 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4555 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4556 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4557 some other programs unwisely rely on these undocumented vars.
4558 But put in warning comments about them.
4559 Problem reported by Ralf Wildenhues in
4560 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4561 * NEWS: Document that these variables are intended to go away.
4563 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4565 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4566 and set the language to C++ (analogous to the equivalent Fortran
4567 tests).
4569 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4570 * doc/autoconf.texi (C++ Compiler): Document it.
4571 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4572 * NEWS: Update.
4574 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4576 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4577 that caused config.status to generate 100-command sed scripts; the
4578 portable limit is 99.
4580 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4582 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4583 variable `ac_d' instead of `d' to avoid infringing namespace.
4584 Report by Ralf Menzel.
4586 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4588 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4589 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4590 * tests/tools.at (autoconf: subdirectories): New test, taken from
4591 the corresponding problem report by Ralf Wildenhues in:
4592 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4594 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4595 Quote some uses of shell variables if they might suffer unexpected
4596 globbing. This doesn't fix all instances of quoting problems that
4597 I found, just the easy ones that look safe.
4598 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4599 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4600 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4601 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4602 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4603 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4604 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4605 Likewise.
4606 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4607 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4609 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4611 * bin/autoreconf.in ($help): Reword according to the manual.
4612 Suggested by Olly Betts.
4614 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4615 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4617 * bin/autoreconf.in: Pass the directory argument to
4618 `require_configure_ac'. Fix comment.
4619 * tests/torture.at (Configuring subdirectories): Expose this.
4620 Reported by Olly Betts.
4622 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4624 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4625 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4626 Automake as follows:
4628 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4629 `$configure_in' instead of `configure.in', to preserve
4630 directory component.
4632 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4634 * config/config.guess, config/config.sub, config/texinfo.tex,
4635 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4637 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4639 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4640 test for C99 conformance; (bool) 0.5 is an integer constant
4641 expression, but (bool) -0.5 is not. Problem reported by Fedor
4642 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4644 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4646 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4647 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4648 Warn about obsolete install-sh files. Remove stray sentence
4649 fragment and fix cross reference.
4650 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4651 install -d; this undoes the 2006-05-10 change.
4652 (MKDIR_P): Mark with AN_MAKEVAR.
4653 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4654 that we don't require $INSTALL to be thread-safe. Move comments
4655 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4656 of AC_PROG_INSTALL. Output a message saying that we're checking
4657 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4658 MKDIR_P instead of AC_SUBST.
4659 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4660 Special magic for MKDIR_P, too.
4661 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4662 a dnl.
4663 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4665 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4667 Sync from Automake, as follows:
4669 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4670 * config/install-sh: Initialize IFS, so field splitting isn't
4671 turned off later.
4672 * config/mkinstalldirs: Likewise.
4673 * config/missing: Remove superfluous quotes. Replace all uses of
4674 `[' by `test', for consistency, and for..
4675 * config/missing (sed_minuso, sed_output): New variables.
4676 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4677 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4678 Fixes `missing' to detect `--output' for help2man. Fixes
4679 PR automake/483. Report by Dennis J. Linse.
4680 (autom4te): Document in `missing --help'.
4682 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4684 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4685 * config/install-sh: Don't use 'path' to talk about file names,
4686 as per GNU coding standards. Close a race condition reported by Ralf
4687 Wildenhues and Stepan Kasal. There is still a race condition
4688 on hosts that predate Posix 1003.1-1992, but we can't help this.
4689 Don't mishandle weird characters like space on pre-Posix hosts.
4690 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4691 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4692 AC_PROG_MKDIR_P from AS_MKDIR_P.
4693 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4694 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4695 earlier editions are not (including Automake 1.8.3).
4696 Do not suggest mkinstalldirs for thread-safety.
4697 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4698 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4699 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4700 presence of special characters and race conditions.
4701 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4702 in Autoconf's name space.
4704 2006-05-10 Bruno Haible <bruno@clisp.org>
4705 and Paul Eggert <eggert@cs.ucla.edu>
4707 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4708 from Automake with minor changes.
4709 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4711 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4713 * config/install-sh: Update to Automake CVS version, as follows:
4714 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4715 * lib/install-sh: Simplify the expr implementation of dirname.
4716 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4717 * lib/install-sh: Handle --, and diagnose unknown options.
4719 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4721 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4722 `./autom4te' to create `./testsuite', since the `all' target
4723 will ensure its presence, but `installcheck' should not create
4724 the uninstalled wrappers.
4726 * tests/torture.at (Unusual Automake input files): Skip if we
4727 detect automake < 1.8.
4729 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4731 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4732 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4733 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4734 * NEWS: Update.
4736 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4739 munge (multiple) white space and other oddities.
4740 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4741 single quotes in variable assignment.
4742 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4743 and similar failures by adding multiple spaces, tabs, and other
4744 special characters.
4745 Report and different test suggested by Francesco Romani
4746 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4748 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4749 single quotes, we only need to search for single quotes; this
4750 both simplifies the search pattern, and makes us less
4751 susceptible to `echo' variations for arguments not containing
4752 single quotes.
4753 (_AC_ARG_VAR_VALIDATE): Likewise.
4755 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4757 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4758 `$*' and IFS concatenation issue with traditional shells and
4759 bash-2.04. Report by Seanster@Seanster.com.
4761 2006-05-03 Bruno Haible <bruno@clisp.org>
4763 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4764 precisely which Mac OS X versions have the od problem.
4766 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4768 * doc/autoconf.texi: Use @option systematically.
4770 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4771 and Bruno Haible <bruno@clisp.org>
4773 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4774 about 'od'.
4775 (Integer Overflow): Mention the special case of integer division
4776 overflow.
4778 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4780 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4781 traditional shells like the Solaris one that do not use the
4782 first IFS character for assembling `$*'.
4783 Prompted by a related report from autoconf_bug@nro.ca.
4785 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4786 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4788 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4789 Mention more problems with the -e option.
4791 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4793 * NEWS: Typo.
4794 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4796 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4797 in URLs to improve DVI formatted output (requires texinfo 4.6).
4798 (System Services, Systemology, Shellology): Likewise.
4799 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4800 output.
4802 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4803 continuous text.
4804 (Runtime): Fix macro argument names to match description:
4805 `action-if-found' -> `action-if-true' and similarly.
4806 (Obsolete Macros): Likewise.
4807 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4808 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4809 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4811 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4813 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4815 * ChangeLog: Typo.
4816 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4817 DVI output.
4819 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4821 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
4822 /bin/sh set unsorted output.
4823 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
4824 * tests/local.at: Likewise.
4826 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
4828 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
4829 (Integer Overflow, Null Pointers, Buffer Overruns):
4830 (Floating Point Portability, Exiting Portably): New sections.
4831 (Writing Test Programs): Fix some langauge. Recommend exiting
4832 with status 1, not merely nonzero. Clarify exit declaration.
4833 (Run Time): Move C exit status stuff to new Exiting Portably section.
4834 (Systemology): Mention Posix and levenez. Update v7 reference.
4835 (Portable Shell): Mention the Posix shell.
4837 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4839 * bin/autoconf.as (me): Replace by as_me.
4841 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4843 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4844 since as_me isn't set yet.
4846 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4848 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4849 a few minor bugs in this area.
4851 * doc/autoconf.texi (Programming in M4sh): Comment out the
4852 documentation of AS_BASENAME, for now.
4853 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4854 (Limitations of Builtins) <basename>: Do not refer to
4855 AS_BASENAME.
4856 * bin/autoconf.as (me): Don't use AS_BASENAME.
4857 (dir): Remove the unused variable.
4858 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4859 AS_DETECT_REQUIRED. All uses changed.
4860 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
4861 All uses changed.
4862 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
4863 (AS_BASENAME): Use "basename --" to protect against leading "-".
4864 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
4865 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4866 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4867 (_AS_DIRNAME_PREPARE): Likewise.
4868 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4869 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4870 (AS_DIRNAME): Use "dirname --".
4872 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4874 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4875 of "run time" and "run-time" changed to "runtime", for consistency.
4876 * lib/autoconf/fortran.m4: Likewise (in comment).
4877 * lib/autoconf/functions.m4: Likewise.
4878 * lib/autoconf/general.m4: Likewise.
4879 * lib/autoconf/headers.m4: Likewise.
4881 * doc/autoconf.texi (Run Time): Document the exit status situation
4882 with more accuracy and detail.
4884 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4886 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4887 Archive is not officially `GNU' any more. Update URL.
4888 (Defining Directories): Likewise
4889 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4891 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4893 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4894 newline from the `trap' code to finish `config.log'; the NetBSD
4895 /bin/sh resets the exit status after an empty command, as
4896 documented in doc/autoconf.texi.
4897 Reported by Dalibor Topic <robilad@kaffe.org>.
4899 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4901 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4902 Suggested by Bruno Haible.
4904 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4906 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4907 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4908 Instead, just list the shells that we know work.
4909 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4910 changed. Be more cautious about the _cv_ variable.
4911 * tests/tools.at (Syntax of the shell scripts): Check the
4912 _cv_ variable once, at first, to avoid an internal autoconf error
4913 when sh -n does not work.
4915 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4917 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4919 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4921 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4922 use ">&-" since we're only 99.999% sure that this is portable,
4923 and since the MinGW bug is fixed in a different way.
4924 * lib/autotest/general.m4 (AT_INIT): Likewise.
4926 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4928 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4929 before opening config.log, to avoid hitting a bug on MinGW.
4931 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4933 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4934 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4935 This works around a MinGW bug reported by Eric Paire.
4936 Make sure that all writes to the log file append to it,
4937 rather than possibly losing data.
4938 * lib/autotest/general.m4 (AT_INIT): Likewise.
4940 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4942 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4943 description.
4945 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4947 * NEWS: Update.
4949 * configure.ac (AC_INIT): Bump to 2.59d.
4951 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4953 Version 2.59c.
4955 * Makefile.maint (news-date-check): Do not require a leading `*'
4956 before the release date in NEWS.
4958 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4959 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4961 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4962 the instantiated file do not contain the string 'datarootdir'
4963 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4964 @mandir@, replace the reference '${datarootdir}' by the value.
4965 * tests/torture.at (datarootdir workaround): New test.
4966 * NEWS: Advertise this temporary fixup.
4967 Based on a patch by Bruno Haible, reported and analyzed by
4968 Paul Eggert and Noah Misch.
4970 2006-04-12 Eric Blake <ebb9@byu.net>
4972 * tests/autotest.at (Debugging a failed test): Fix comment.
4974 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4976 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4977 all the changes since 2006-04-07.
4979 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4981 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4982 succeeded, but `ln -s file dir' failed, take care to remove the
4983 leftover target before the next test, to prevent its spurious
4984 failure; also make sure `ln file dir' works before selecting it.
4985 Thanks to Keith Marshall for pointing this out.
4986 * THANKS: Update.
4988 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4989 assignments in `at_debug_args', so that we put them correctly
4990 in the `run' script.
4991 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4992 Reported by Eric Blake.
4994 2006-04-11 Eric Blake <ebb9@byu.net>
4996 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4997 top-level tests after micro-suite has been run. Used in...
4998 (Debugging a successful test, Debugging script and environment),
4999 (Debugging a failed test): ...these new tests. The first of these
5000 is fixed by...
5001 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5002 macro, split out from...
5003 (AT_INIT): ...here, so that using -d also generates a run script.
5004 Document that -d inhibits top-level logging.
5005 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5006 inhibits top-level logging; debug scripts are created.
5008 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5009 check.
5010 * tests/autotest.at (Empty test, Empty check): New test to check it.
5012 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5013 from gcc.
5015 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5017 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5018 the files if a problem appears. Make the empty *.at files
5019 read-only, too. Proposed by Ralf Wildenhues.
5021 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5023 * config/Makefile.am: Add comment to force updated Makefile.in.
5025 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5026 space only patch to this file, this patch causes the Makefile.in
5027 files that include freeze.mk to be updated, and thus have a
5028 newer time stamp again, which in turn makes a pristine CVS
5029 checkout have correct time stamps.
5031 * Makefile.maint (cvs-sv): New macro, to be used..
5032 (config.guess-url_prefix, config.sub-url_prefix)
5033 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5034 point to CVS text checkout of Gnulib files.
5035 (copyright-check): Bump current year.
5036 (announcement): Do not hard-wire `./announce-gen'.
5037 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5038 correctly.
5039 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5040 `chmod +x'.
5041 (wget_files): Update config.guess, config.sub, texinfo.tex by
5042 `wget-update', now that their URLs work again.
5044 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5046 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5047 Problem noted by Paul D. Smith.
5049 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5051 * doc/autoconf.texi: Remove unused words from word list.
5052 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5053 .x-sc_trailing_space: New files.
5055 * doc/standards.texi: Sync from gnulib.
5057 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5058 `LIBOBJDIR' as experimental.
5060 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5061 with a target directory; it's internally implemented as `cp'
5062 anyway, but since Autoconf advertises the possibility to use
5063 a target directory when LN_S is `ln -s', we need to find out.
5064 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5065 analyzed by Keith Marshall <keith.marshall@total.com>.
5067 * THANKS: Update.
5069 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5071 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5072 confdefs.h as-is. In general, if it has backslash-newline or the
5073 like, then it doesn't work either to sort or to remove empty
5074 lines.
5076 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5078 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5080 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5082 * lib/autom4te.in (Automake-preselections): Preselect
5083 _AM_SUBST_NOTMAKE.
5085 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5087 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5088 apostrophe within a single-quoted string, as this is the usual
5089 tradition and is easier to read than '"'"'. Don't rely on the
5090 shell treating "$/" like '$/'. Use a more-consistent indenting
5091 style for the trap.
5093 2006-04-09 Eric Blake <ebb9@byu.net>

5180 _AS_DETECT_BETTER_SHELL:
5182 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5183 skip nonexistent directories.
5184 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5185 only shell candidates which exist.
5186 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5187 * lib/autotest/general.m4 (AT_INIT): No need to give three

5190 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5191 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5193 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5194 distinguish m4sugar macros.
5195 * tests/tools.at (autoupdating with aclocal and m4_include):

5197 test case by Noah Misch <noah@cs.caltech.edu>.
5199 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5201 Revert my change from 2006-03-17, in other words:
5202 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5203 and DUALCASE=1.
5204 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
5205 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
5206 it is set.
5208 2006-04-07 Eric Blake <ebb9@byu.net>
5210 * doc/autoconf.texi (Programming in M4sh): Document that
5211 AS_MKDIR_P exits the script on failure.
5212 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5214 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5216 * config/elisp-comp, config/install-sh, config/mdate-sh,
5217 config/missing, config/mkinstalldirs: Sync from Automake.

5233 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5235 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5236 whether `set' quotes correctly: redirect stderr of the tested
5237 `set', and use a subshell, for Ultrix; use `sed' instead of
5238 `grep' for zsh `set' which may write binary output; match only
5239 at the beginning of a line, to avoid false positives.
5240 In order to avoid false positives by unrelated variables with
5241 multiline content, put the dump algorithm in a subshell and
5242 unset all variables containing newlines (except some which are
5243 special to the shell). Warn about cache variables that are
5244 unset.
5246 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5257 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
5258 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
5259 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
5260 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
5262 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
5263 shell issue with double-quoted command substitutions of native
5264 commands.

5285 * tests/Makefile.am (maintainer-check-posix):
5286 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
5288 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5289 ac_config_<foo>s again, sometimes normalized, sometimes not.
5290 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5291 (AC_CONFIG_COMMANDS): Do not do so here.
5292 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5293 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5294 2005-07-25 rewrite. Noticed by Noah Misch.
5296 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5297 _AC_PRESERVE_HELP_ORDER, ...
5298 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5300 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
5301 inside m4_expand_once; it is redundant.

5304 for --help from Cygnus `configure.'
5306 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5346 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
5347 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
5348 normalizing it, consistent it with previous releases.

5351 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5353 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5354 Use simplified args that Eric Blake originally suggested.
5356 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5358 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5359 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5360 Use 'comm' rather than N instances of grep; this also fixes a bug
5361 whereby substrings were incorrectly matched, causing us to not
5362 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5363 (exclude_list): Exclude empty macros.

5377 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
5379 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
5380 report request when we have no AC_PACKAGE_BUGREPORT.
5382 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5447 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5448 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5449 ac_file to the name of the default output file and call
5450 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5451 initial `rm' of the candidate files...
5452 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5453 the same list in subsequent `rm' calls, and for the temporary
5454 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

5456 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5457 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5458 no longer needed) by libtool. Make it a cache check.
5459 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5460 copied here by mistake.
5461 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5462 _AC_COMPILER_EXEEXT.

5498 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
5499 subordinate tools.
5500 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
5501 * doc/autoconf.texi (autoreconf Invocation): Document it.
5503 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

6238 by the function rather than ignoring it.
6239 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6240 comparing its address. Intel's interprocedural optimization was

6274 problems if the testsuite were running too fast.
6276 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6278 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6279 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6280 (which belong to Xt, not X itself). See Debian bug 327655.
6281 * NEWS: Mention this.

6290 suggested by Ben Elliston. Handle weird characters correctly.
6292 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6294 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6295 calls, so that the final expansion of this macro is shorter.
6296 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6297 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6298 the cleanup there. Use AS_VAR_* macros, to be more general.
6299 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6301 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6303 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

6321 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6323 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting

6325 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6326 "if $undefined_var;" succeeds with my shell.
6328 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6329 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6330 but change the m4_divert_text to m4_divert_once.

6342 parameters by the first character from IFS.

6348 first header appears, define AH_HEADER.
6349 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6350 Update limitations about when to call AC_CONFIG_HEADERS.
6351 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6352 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6353 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6354 ``Configuration Actions''; fix their index entries.
6356 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6357 options correctly. Process N-M as M-N if M is smaller than N.
6358 Process ranges correctly so that N-N will run only N.
6359 Sort and uniquify the tests that will be run. If there is more
6360 than one test, reinsert the banners for the tests.

6366 before passing the macro name to AH_TEMPLATE.

6389 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6391 When building in place, set srcdir="."; suggested by Tim Van Holder.
6393 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6394 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6395 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6396 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6397 does not mean "no --srcdir option".
6399 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6401 * tests/autoscan.at (autoscan): New file.

6404 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
6406 * tests/autotest.at (Keywords): Test keywords combinations.
6408 2005-08-12 Stepan Kasal <kasal@ucw.cz>
6410 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6411 add "2>&1"; gzip 1.2.4 prints help on stderr.
6413 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6415 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6416 was pushdef'ed twice while popped only once. Push it only once.
6417 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.

6428 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6429 "<tab>" in comment, so that the point is understandable.
6431 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6433 Rewrite substantial part of lib/autoconf/status.m4.
6434 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6435 and CONFIG_COMMANDS are not processed in four separate loops.
6436 Instead, there is one main loop. This alows that the common code
6437 is expanded only once, thus config.status (and configure) is smaller.
6439 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6440 the AC_LIST_FILES and cousins macros are no longer used.
6442 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6443 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6444 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6445 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6446 contain the initialization, nor the for loop, nor the associated
6447 commands; all these go to ...
6448 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6449 _AC_OUTPUT_CONFIG_STATUS.
6450 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6451 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6452 (_AC_OUTPUT_FILE): The creation of the sed script ...
6453 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6454 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6455 _AC_OUTPUT_MAIN_LOOP.

6471 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6472 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6473 this didn't belong to the `config commands' section.
6474 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6475 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6476 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6477 to the `config commands' section either.
6478 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6479 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.

6496 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6497 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6498 with AU::AC_OUTPUT.
6499 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6500 in AC_OUTPUT doesn't double-quote it either.
6501 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6502 parameters.

6526 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6527 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6528 (AC_ARG_VAR): ... here.

6540 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6541 to INIT_PREPARE.
6542 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6543 its value to shell variable ac_precious_vars and call
6544 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6545 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6546 _AC_ARG_VAR_VALIDATE.

6582 versions of autoconf.
6584 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6586 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

6591 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6592 sed substitution command, so that we allow | in program prefixes

6596 configure_input, top_builddir, srcdir, etc.
6597 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6598 PATH_SEPARATOR in AUTOTEST_PATH.
6600 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6608 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6609 directories with weird names. Apparently some people like living

6630 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
6631 document to output the default config_* lists to config.status.

6633 Likewise for --header; moreover, recognize --he and --h as shortcuts
6634 for --help in that case.
6636 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6637 matches the order of execution. No code changed.

6659 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
6660 (AC_SUBST): Call it.
6661 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6662 the directory specific variables; but don't call it for configure_input.
6664 2005-06-28 Derek Price <derek@ximbiot.com>
6666 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6667 addition.
6669 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
6671 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
6672 directory have inherent problems with special characters like spaces,
6673 due to limitations in Make syntax. Problem reported by Alexandre
6674 Duret-Lutz.
6675 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

6690 variable into diagnostic. Make the diagnostic an error, not a warning,
6691 because we really don't support spaces and suchlike in dir names.
6692 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6693 Don't worry about backslashes in srcdir; it can't happen now.
6694 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
6695 Simplify ac_optarg handling.

6710 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
6712 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

6718 2005-06-21 Stepan Kasal <kasal@ucw.cz>
6720 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
6721 b, t, r, w commands require single space, while : cannot have any.
6722 (Special Shell Variables): Fix sed code this in the example.
6723 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
6724 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
6726 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
6727 expand to the empty list. Don't use two pairs of m4_changequote,
6728 it's not necessary.
6730 2005-06-20 Derek Price <derek@ximbiot.com>
6732 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

6736 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
6737 * doc/autoconf.texi:
6738 Don't mention Solaris versions so much, if a
6739 problem is common to all extant versions of Solaris. Say "SunOS
6740 4" instead of "SunOS" for SunOS 4.
6741 (awk): Mention more of the limitations of traditional Awk.
6742 (cat): Don't talk about cat -v.
6744 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

6749 to be compatible with glibc strverscmp.
6750 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
6752 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
6753 on Mac OS X 10.4 reported by Peter O'Gorman in:

6755 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
6756 Use shell builtins rather than 'expr', to work around expr bug.
6758 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
6760 * doc/autoconf.texi: "filesystem" -> "file system".
6761 "behaviour" -> "behavior".

6774 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
6775 quotes and backslashes. Patch from Derek Price.

6780 AS_TR_SH.
6782 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
6784 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6785 -u, since it outputs chatter if the input files are the same.
6786 Problem reported by Ralf Menzel.
6788 2005-06-08 Derek Price <derek@ximbiot.com>
6790 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6791 renaming them since they are about to be redefined anyhow.
6793 2005-06-08 Derek Price <derek@ximbiot.com>
6795 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6796 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6797 Move m4_undefine to alphabetical order.
6799 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6801 * README: Recommend GNU M4 1.4.3 or later.
6802 * doc/autoconf.texi (Introduction): Likewise.
6803 Reword to avoid some formatting glitches.
6804 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6805 Clarify explanation of HP compiler bug.
6806 Redo example output tp match current CVS snapshot.
6807 Use @example.org in email addresses when the examples
6808 might get inadvertently cut-and-pasted into user code.
6809 Remove example of autom4te usage that doesn't seem to work now.
6810 Use modern AC_INIT (except when the example is meant to be
6811 shown with Autoconf 2.13).
6812 Update ksh info for Solaris 9 and later.
6813 KB -> kB.
6814 Modernize description of Automake versions a bit.
6815 Don't claim a future version of Autoconf is near.

6822 Reword to avoid some formatting glitches.
6823 * doc/installt.exi: Reword to avoid some formatting glitches.
6825 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6826 Tru64 ksh pattern matching bug. Reported against Libtool by
6827 Albert Chin <libtool@mlists.thewrittenword.com> and
6828 Nicolas Joly <njoly@pasteur.fr>.
6830 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6832 m4_cdr of one-member list was [[]] (one-member list containing an
6833 empty string) instead of [] (an empty list. Callers were skewed to
6834 match this misbehaviour. As a consequence of this:
6835 - m4_foreach([x], [], [foo]) expanded to `foo', while
6836 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6837 This bug has been fixed:
6839 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6840 expand to an empty string; print error msg if called without
6841 an argument list.
6842 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6843 misbehaviour; handle [] and [[]] correctly.

6851 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6853 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6854 swallow records with more than 99 fields.
6855 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6856 parse the long line.
6858 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6860 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6861 swallow literals longer than 399. Reported by Ralf Wildenhues.

6865 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
6867 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6868 to gfortran, and make these the first two compiler names
6869 checked (following the general autoconf preference for gcc).
6871 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6873 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

6879 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6880 expression of unbounded size when processing the --list
6881 option. This runs afoul of a limit of 399 bytes per regular
6882 expression on AIX. Problem reported by Ralf Wildenhues.
6884 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

6893 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6895 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6896 now contain newlines, and substituted files must be referenced on
6897 a line alone; the sed scripts to substitute them are now very
6898 different.
6899 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6900 commands can be put in a sed script portably.
6901 * doc/autoconf.texi (Setting Output Variables): Document above

6906 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
6908 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
6909 From Ralf Menzel (trivial change).
6911 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6913 * tests/local.at: Don't attempt to check for negated character
6914 classes in shell scripts. The test was too brittle.
6916 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6918 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6919 * doc/autoconf.texi (Limitations of Builtins): Document this
6920 limitation.
6922 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6924 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6925 common code; used in many places in the tree.
6926 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
6927 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6929 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
6931 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
6932 messages when ac_unique_file is not found.
6933 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6934 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6935 commands, for consistency with AC_MSG_ERROR and such.
6937 * bin/autoconf.as: Make more use of "shift 2" in option processing.
6939 * bin/Makefile.am: Merge the two rules for creating scripts.
6941 2005-05-23 Stepan Kasal <kasal@ucw.cz>
6943 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
6944 obsolete; it was never documented.
6945 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
6947 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6949 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6950 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6951 (ac_top_builddir): ... this ...
6952 (ac_top_build_prefix): ... to this; the old name is also kept, for
6953 backward compatibility.
6954 (ac_top_builddir_sub): New variable, without the trailing slash,
6955 always nonempty.
6956 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6957 * doc/autoconf.texi (Configuration Actions): Rename
6958 ac_top_builddir to ac_top_build_prefix.
6959 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
6960 at_top_builddir to at_top_build_prefix.
6961 * lib/autotest/general.m4 (AT_INIT): Likewise.
6963 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6965 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6966 of confdefs.h .
6968 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6970 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6971 argument to m4_foreach. I guess it was necessary in the past,
6972 but I think it's a no-op now.
6974 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6976 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6977 ``cat <<_ACEOF'' commands to one.
6978 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6979 * lib/autoconf/status.m4: On various places, use expr instead of
6980 ``echo|sed.''
6981 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6982 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6983 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6984 a range.
6985 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6986 the wrong patterns between ``case'' and ``esac.'' The previous
6987 code had false positives.
6989 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6991 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6992 as on 2005-05-02.
6993 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
6994 Mention LIBOBJDIR.

7034 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7036 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7037 check.
7038 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7039 enough arguments, similarly as in m4_bpatsubsts.
7041 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7043 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7044 of absolute paths.
7046 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7048 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7049 for absolute directory names in one loop.
7050 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7051 abbreviations of --version and --debug.
7053 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7055 * doc/autoconf.texi (Autoconf Language): Be more precise about
7056 quoting rules. Problems noted by Stepan Kasal.
7057 Also, throughout this document, be more careful about white space.
7058 "blank", "white space", and "space" all have different meanings
7059 and we should be careful to say what we mean.
7061 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7063 Fix C++ related problems reported by Werner Lemberg.
7064 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7065 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7066 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7067 avoid problems with C++ and throw.
7068 * tests/compile.at: .cpp, not .cc.
7070 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7072 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7074 * doc/autoconf.texi (Generic Functions): Typos.
7076 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7078 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7079 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7080 set by latest automake.
7082 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7084 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7085 outputs 0 on GNU/Linux these days.
7087 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7089 * doc/autoconf.texi (Autoconf Language): Add more description
7090 about quoting heuristics.
7091 (Limitations of Builtins): Describe "set -" problems.
7093 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7095 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7096 not newline.
7098 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7099 by AC_DEFINE; it was a mistake.
7100 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7102 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7104 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7106 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7108 * doc/autoconf.texi (External Software): Quadrigraphs are not
7109 processed correctly in AS_HELP_STRING; avoid this in the examples.
7110 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7111 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7112 comment and reduce m4_default([foo], []) to [foo].
7113 (m4_strip): Update the explanation.
7115 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7117 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7118 Remove core.conftest.* too; it's generated by Tru64 5.1.
7119 Problem reported by Jennis Pruett.
7120 * lib/autoconf/functions.m4
7121 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7122 Don't bother to remove core files; AC_RUN_IFELSE should do that
7123 for you.
7125 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7127 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7129 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7131 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7132 Report from Horst Wente.
7134 2005-04-15 Stepan Kasal <kasal@ucw.cz>
7136 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
7137 the comment.
7139 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7141 * doc/autoconf.texi (External Software, Package Options): Add
7142 examples showing how to implement --with-* and --enable-* options.
7144 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7146 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7147 as well as configure.in. Problem reported by Gregorio Guidi.
7149 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7151 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7152 pattern for alloca snippet.
7154 2005-04-04 Stepan Kasal <kasal@ucw.cz>
7156 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
7158 2005-04-01 Stepan Kasal <kasal@ucw.cz>
7160 * doc/autoconf.texi (Generic Programs): Fix a typo.
7162 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
7164 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7165 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7167 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7169 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7170 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7171 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7172 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7173 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7175 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7177 * NEWS: The configure command now warns you if you attempt to use
7178 a directory whose name contains a special character like space,
7179 newline, or "\".
7180 * doc/autoconf.texi (Installation Directory Variables): Allow
7181 "," in file names. Do not use \@; it's not a portable regexp.
7182 * bin/Makefile.am (edit): Likewise.
7183 * lib/Makefile.am (edit): Likewise.
7184 * tests/Makefile.am (edit): Likewise.
7185 * tests/semantics.at: Likewise.
7186 * tests/torture.at: Likewise.
7187 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7188 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7189 * doc/autoconf.texi (File System Conventions): Warn about
7190 unportable file names.
7191 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7192 (AC_INIT): Use it.
7193 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7194 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7195 ac_pwd, and quote srcdir.
7196 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7198 * doc/autoconf.texi: Fix some systematic formatting problems.
7199 ".)" needs a following @: if not at the end of a sentence, and
7200 similarly for "!)". "etc." should be preceded by a comma.
7201 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7203 2005-03-22 Bruno Haible <bruno@clisp.org>
7205 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7206 argument is often called 'build-aux'.
7208 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7210 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7211 macro AC_TRY_LINK is obsolete.
7212 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7213 `AC_CONFIG_FILES'.
7215 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7217 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7218 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7219 from a Common Lisp's `cl'.
7220 (AC_PROG_CXX): Behave according to the documentation: don't
7221 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7222 make the variable CCC precious; use `cl.exe', not `cl'.
7224 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7225 Alexandre Duret-Lutz <adl@gnu.org>
7227 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7228 /dev/null, as "configure" shouldn't read stdin, and this insulates
7229 us from problems (e.g., when testing for "cl"). Also, do this
7230 redirection before invoking "hostname" or "uname", and keep the
7231 original input stream available via...
7232 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7233 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7234 bother with "</dev/null" since it's now done at the top of
7235 'configure'.
7236 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7237 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7238 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7239 * doc/autoconf.texi (File Descriptor Macros): New section.
7240 (Printing Messages): Mention it.
7241 * tests/base.at (Input/Output): New test.
7243 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7245 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7246 newline if neither \c nor -n work, as that would output two
7247 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7249 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7251 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7252 This causes that any required macros inside will get before the if.
7253 * doc/autoconf.texi (autom4te.cache): A typo.
7255 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7257 Undo previous change, except keep the change to
7258 lib/autoconf/programs.m4 that replaced grep with shell
7259 pattern-matching. This is because net-snmp configure reads stdin.
7260 Reported by Noah Misch.
7262 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7264 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7265 from /dev/null, as "configure" shouldn't read stdin, and this
7266 insulates us from problems (e.g., when testing for "cl").
7267 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7268 before invoking "hostname" or "uname".
7269 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7270 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7271 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7272 "</dev/null" since it's now done at the top of 'configure'.
7273 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7274 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7275 Also, replace grep with shell pattern-matching, to save a process.
7277 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7279 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7280 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7281 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7282 compiler.
7284 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7286 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7287 grep -q isn't portable. Improve grep -s explanation.
7288 Problem reported by Dan Manthey.
7290 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
7292 * doc/autoconf.texi (Special Shell Variables): Clarify
7293 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
7295 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7297 * doc/autoconf.texi: Use @acronym for DJGPP.
7298 Fix some @code's that should have been @env's, and vice versa.
7299 Sort environment variable names.
7300 Mention that shells no longer inherit IFS.
7301 Don't recommend PATH_SEPARATOR=';' so strongly.
7302 Mention that $RANDOM might expand to the empty string.
7303 "symlink" and "soft link" -> "symbolic link".
7304 Improve mktemp description (reported by Bruno Haible).
7306 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
7308 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
7309 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
7310 Likewise.
7311 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
7312 Likewise.
7314 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
7316 * NEWS: Mention AT_COPYRIGHT.
7318 * tests/local.at (AT_CMP): Use diff directly on input files rather
7319 than copying them.
7321 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
7322 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
7324 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7325 and Paul Eggert <eggert@cs.ucla.edu>
7327 * tests/autotest.at (Empty test suite): New test.
7328 * tests/torture.at (Substitute and define special characters)
7329 (Substitute a 2000-byte string, Define to a 2000-byte string)
7330 (Substitute a newline, Define a newline): New tests.
7332 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7334 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
7335 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
7336 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
7337 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
7338 (Standard regular expressions): New test.
7339 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip

7344 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
7345 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

7380 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7382 Try not to generated lines of unlimited length, as POSIX places a
7383 2047-byte limit on line length of portable text files.
7384 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7385 Use newline as a separator, not space.

7443 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7444 Update the long comment explaining it.
7446 m4_require no longer writes an ``is required by'' line to the
7447 execution stack. It contains only one bit of non-redundant
7448 information: that the macro was required, not called. And even
7449 this bit is useless in most situations: have you ever met a macro
7450 which both calls and requires the same macro?
7452 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7453 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7460 (_m4_require_call): Use it.
7461 * tests/m4sugar.at (m4_require): Expect output without the
7462 ``is required by'' messages.
7464 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7466 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
7467 rather than x for expr.
7469 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
7470 this is safe.
7471 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
7472 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

7487 config.h.in is always recreated when --force.

7493 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
7495 * doc/autoconf.texi (Limitations of Builtins): Clarify that
7496 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
7498 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
7500 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7501 Warn about newline stripping in `` and $(). Update Solaris
7502 version to 9.
7503 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7504 X insulates us from future changes to Posix.
7505 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7506 stripping.
7508 2005-01-19 Stepan Kasal <kasal@ucw.cz>

7528 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
7530 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7532 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7554 (_m4_divert_n_stack): New macro; the expansion is
7555 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
7556 otherwise.
7557 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
7558 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7559 stored in _m4_divert_diversion or _m4_divert_dump.
7560 (m4_divert_pop): When the parameter is given, compare the symbolic
7561 name with the last diversion pushed on the stack. Previously, the
7562 current diversion was compared with the numeric value of the
7563 diversion given as the parameter.
7564 (m4_require): If the macro hasn't been expanded yet, call ...
7565 (_m4_require_call): this new macro.

7598 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

7600 not essential. Reported by Magnus Therning.
7601 * tests/torture.at (autoreconf.): New banner.
7602 (autoreconf and non-AC configure): Rename to `Non-Autoconf

7651 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
7652 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

7814 * doc/autoconf.texi (Libraries): Clarify problems with AC_CHECK_LIB
7815 and suggest AC_SEARCH_LIBS. Suggested by Noah Misch and Stepan Kasal.
7817 2004-12-08 Noah Misch <noah@cs.caltech.edu>
7819 * configure.ac (test suite): Cease to generate wrapper scripts.

7824 (wrapper.in): Generate it in the build directory.
7825 (MAINTAINERCLEANFILES): Delete wrapper.in.
7826 (CLEANFILES): Add wrapper.in.
7827 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
7828 the output. Replace each $as_me with a @wrap_program@.
7829 * tests/wrapper.in: Delete it; we always build it.
7831 * bin/Makefile.am (autoconf.in): Generate it in the build directory.

7842 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
7844 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7846 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
7847 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
7848 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
7849 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
7851 2004-12-07 Stepan Kasal <kasal@ucw.cz>
7853 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

7865 out the common code to ...
7866 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
7867 value of the #define--default to 1, iff the macro was called
7868 with exactly one parameter.
7870 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
7872 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7873 "char c = '\200';" rather than "char c = 0x80;" as the
7874 latter doesn't conform to the strict C standard due to
7875 overflow on signed char hosts.
7877 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
7878 to -qlanglvl=ansi. We don't want to disable extensions.

7938 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
7939 the $1_found variable, don't test whether the file is executable;

7977 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
7978 Problem reported by Stepan Kasal.
7980 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
7982 Fix problems reported by Andreas Buening in:
7983 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
7984 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
7985 in test makefile.
7986 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
7987 readable; it's not true in OS/2-emx.
7989 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7991 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7992 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7993 (trivial change). Problem and patch reported by Andrew Church in:
7994 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7996 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
7998 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

8023 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8024 texinfo.tex for now (done by hand now).
8025 * Makefile.maint (wget_files, cvs_files):
8026 Remove ansi2knr.c; nobody uses it.
8027 (ansi2knr.c-url_prefix): Remove.
8028 (cvs-update): Fix test for failure. I don't know why it ever
8029 worked...
8031 * doc/autoconf.texi: Update URLs, some of which went stale.
8032 Use @uref rather than @href.
8034 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8035 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8037 * config/config.guess, config/config.sub, config/elisp-comp,
8038 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8039 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8041 * NEWS, TODO, configure.ac, bin/autoscan.in,
8042 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8043 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8047 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8048 tests/tools.at, tests/torture.at:
8049 Use "file name" rather than "filename" or "path",
8050 to be consistent with the terminology of the GNU coding standards.
8052 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8054 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8055 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8056 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8057 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8059 More fixes to support spaces in the name of the build directory.
8060 This isn't a complete fix but it's an improvement.
8062 * bin/autoconf.as (autom4te_options): New var.
8063 Use it instead of appending to AUTOM4TE, so that we can allow
8064 spaces in the build directory's absolute name.
8065 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8066 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

8069 main program): Likewise.
8071 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8073 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8074 From Ralf Corsepius in:

8077 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8079 * doc/autoconf.texi (Function Portability): Document isinf and
8080 and isnan. From a suggestion by Kevin Ryde.
8082 * lib/Autom4te/General.pm (END): Return correct exit status even
8083 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8085 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8087 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8088 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8089 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8091 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8093 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8094 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8095 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8096 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8097 * lib/autom4te.in (Automake-preselections): Preselect
8098 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8100 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8102 * lib/autom4te.in (Automake-preselections): Preselect
8103 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8104 trace them.
8106 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8108 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8109 Tru64.
8110 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8111 Document problem with "`""`" in pdksh POSIX mode.
8113 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8115 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8116 with pdksh, too. Problem reported by Patrick Welche via
8117 Gary V. Vaughan.
8118 * doc/autoconf.texi (Shellology): Note that set -o posix is
8119 useful for pkdsh, too.
8121 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8123 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8124 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8125 Don't fail if ENV or BASH_ENV is readonly.
8126 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8127 etc. are read only. Problem reported by Ludovic Courtes.
8129 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8131 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8132 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8133 (trivial change)
8135 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8137 * doc/autoconf.texi (File System Conventions): Warn about
8138 names like "aux". Problem reported by Eric Blake.
8140 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8141 by zero instead of array size, so that we can use any arithmetic
8142 constant expression (instead of requiring an integer constant
8143 expression). This allows us to test expressions like DBL_MAX <
8144 LDBL_MAX, which didn't conform to the C standard using the old
8145 method.
8146 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8147 now that we can do floating-point tests at compile time.
8149 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8151 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8152 and LDBL_EPSILON, as the resulting expression isn't an
8153 integer constant expression and violates the C standard.
8154 Problem reported by Nelson H. F. Beebe. Also, check
8155 for "L" suffix, and check that long double doesn't have
8156 worse range or precision than double, that mixed-mode
8157 arithmetic doesn't generate a diagnostic, that double
8158 constants fit in long double.
8160 2004-06-03 Kevin Ryde <user42@zip.com.au>
8162 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8163 malloc(0) and realloc(NULL,size).
8165 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8166 Bob Proulx.
8168 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8170 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8171 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8172 by Jim Meyering.
8174 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8176 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8177 can be rewritten using if-then-else. Suggested by Bruno Haible.
8179 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8181 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8182 Problem reported by Stepan Kasal.
8184 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8186 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8187 change). Patch reported by Ralf Wildenhues in
8188 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8190 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8191 function F exists if the compiler and linker let you compile an
8192 expression like (F != 0). Recent versions of GCC optimize away
8193 the reference to F in that case, since every function address must
8194 be nonzero, so the link succeeds even if F does not exist.
8195 Problem reported by Manu in
8196 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8198 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8199 "Unix". Many uses changed.
8200 (Limitations of Builtins): Explain better why the ! command isn't
8201 portable.
8203 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8205 * lib/autom4te.in (Automake-preselections): Preselect
8206 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8208 2004-05-19 Kevin Ryde <user42@zip.com.au>
8210 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8211 referencing AC_FUNC_STRERROR_R.
8213 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8214 note pessimistic assumption when cross compiling.
8216 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8218 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8219 (until 2004) invoked subcommands with sh -e, contra POSIX.
8220 Reported by Kevin Ryde.
8222 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8224 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8225 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8226 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8227 `test -f " /usr/bin/grep"', which _always_ failed.
8228 (AC_PROG_SED): Ditto bogus PATH fix.
8229 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8230 requires that grep correctly supports _multiple_ `-e' options, rather
8231 than stating only that grep should accept `-e'.
8233 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8235 Port to C99, which requires that 'exit' be declared.
8237 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8238 to ensure that stdlib.h is included.
8239 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8240 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8241 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8242 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8243 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8244 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8245 when using 'exit' in a test; C99 requires that 'exit' be declared.
8247 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8249 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8250 now prefers 'grep' implementations that accept -e.
8251 (Limitations of Usual Tools): Describe problems of traditional
8252 egrep and fgrep with long input lines, and of traditional grep
8253 with -e.
8254 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8255 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8256 All callers changed. Append /usr/xpg4/bin to the PATH, for
8257 Solaris.
8258 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8259 the user with complaints about multiple -e options.
8260 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8261 Define it with AC_PROG_GREP.
8262 * configure.ac (AC_PROG_GREP): Add.
8263 * lib/freeze.mk (GREP): New macro.
8265 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8267 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8268 a possible candidate only after all others fail, rather than
8269 consulting it first. This improves backward compatibility by
8270 better reflecting the way shell selection occurred in previous
8271 versions of Autoconf, and should help to avoid triggering latent
8272 problems in other packages, such as the one in Automake where zsh
8273 is not handled robustly:
8274 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8275 Although it is not Autoconf's responsibility to work around
8276 problems in Automake, it nevertheless makes sense to avoid
8277 introducing unnecessary incompatibilites.
8279 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8280 Gary V. Vaughan <gary@gnu.org>
8282 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8283 how deeply nested we are when a suitable tool is found, set the
8284 ac_path_TOOL_found flag.
8285 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8286 nested we are in this macro. Break out of all 3 nested loops if
8287 ac_path_TOOL_found is set.
8289 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8291 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8292 of the _AS_PATH_WALK loop too if GNU flavor is found.
8294 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8296 * doc/autoconf.texi (Limitations of Make): Update documentation
8297 for `$<'. New entry `Long lines', based on a report from Simon
8298 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8299 paragraph about DJGPP, based on a mail from Richard Dawe.
8301 2004-04-20 Paul Eggert <eggert@twinsun.com>
8303 * tests/c.at (C keywords): Don't assume that GCC supports
8304 "restrict" and "inline", as sufficiently-old GCC versions do not
8305 (also, GCC configured to be in pedantic C89 mode does not).
8306 Problem reported by Sumit Pandya in:
8307 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8309 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8310 consider -g to work if it generates warnings when plain compiles
8311 don't. Problem reported by Braden McDaniel in:
8312 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8314 * doc/autoconf.texi (Slashes): New section, to document a problem
8315 reported by Jim Meyering in:
8316 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8318 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8319 linker output files before linking, to work around IRIX 6 linker bug.
8320 Problem reported by Rainer Orth in:
8321 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8323 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8325 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8326 best tool so far counter rely on the tool path variable name to
8327 avoid checks for one tool being affected by the results of running
8328 the length check on a previous tool.
8330 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8331 match expression argument, as different greps have different
8332 regular expression flavours.
8333 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8334 literals.
8335 (AC_PROG_EGREP): Pass 'EGREP$'.
8336 (AC_PROG_GREP): Pass 'GREP$'.
8338 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8340 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8341 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8343 2004-03-29 Paul Eggert <eggert@twinsun.com>
8345 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8346 Types, Specific Compiler Characteristics, System Services,
8347 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8348 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8349 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8350 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8351 Likewise.
8352 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
8353 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
8354 AC_TYPE_OFF_T): Likewise.
8355 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
8356 Likewise.
8358 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
8359 pacify libtool 1.5.2. Fix quoting problems in sed command.
8361 2004-03-28 Paul Eggert <eggert@twinsun.com>
8363 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8364 now defines HAVE_DECL_TZNAME if it is declared, when
8365 HAVE_STRUCT_TM_TM_ZONE is not defined.
8366 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8367 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
8368 for HAVE_TZNAME.
8370 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
8372 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
8373 superfluous backslashing of quotes (") in sed expressions;
8374 thanks to Paul Eggert.
8376 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8378 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8379 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8380 H. F. Beebe for the bug report.
8382 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8384 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8385 quoted -cmdline argument in Portland Group compiler (bug
8386 reported by Jeffrey J. Barteet).
8388 2004-03-25 Kevin Ryde <user42@zip.com.au>
8390 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
8391 (Run Time): ... here, where it's now mentioned.
8393 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
8395 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
8396 inherits from language Autoconf-without-aclocal-m4.
8397 (Customizing autom4te): Adjust example; the cache must now be
8398 disabled for language Autoconf-without-aclocal-m4.
8400 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
8401 Nathanael Nerode <neroden@twcny.rr.com>

8409 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
8410 AC_CHECK_TARGET_TOOLS, and warn for future changes
8411 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
8412 AC_CHECK_TOOLS.
8413 (Specifying Names): Document the reason for these future
8414 behavioral changes.
8415 * tests/mktests.sh: Do not generate tests for the
8416 new macros.
8417 * NEWS: Document these changes.
8419 * doc/autoconf.texi: Avoid macros with unbraced arguments,
8420 they make TeX hang up.
8422 2004-03-15 Paul Eggert <eggert@bogus.example.com>
8424 * NEWS: New macro AC_CHECK_ALIGNOF.
8425 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
8426 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
8427 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
8428 vowel.
8429 (AC_CHECK_ALIGNOF): New macro.
8430 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
8431 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
8432 those for sizeof.
8434 2004-03-03 Paul Eggert <eggert@twinsun.com>
8436 * bin/Makefile.am (edit): Don't use $< in a context where
8437 POSIX doesn't require support for it. Use $@.in instead.
8438 Problem reported by Anthony N. Frasso in
8439 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
8440 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
8442 2004-02-23 Gary V. Vaughan <gary@gnu.org>
8444 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
8445 from the next generation of Libtool.
8446 * lib/autom4te.in (Autoreconf-preselections): Ditto.
8448 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8450 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8451 is not always thread-safe. Report from Nathanael Nerode.
8453 2004-02-18 Paul Eggert <eggert@twinsun.com>
8455 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8456 problem on QNX reported by Stephen Rasku in
8457 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
8459 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
8460 $(m4sh_m4f_dependencies); this removes a FIXME.
8461 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
8462 (MAINTAINERCLEANFILES): Split into pieces,
8463 one per related section. Add $(srcdir)/wrapper.in.
8465 2004-02-09 Paul Eggert <eggert@twinsun.com>
8467 * doc/autoconf.texi (Setting Output Variables): Emphasize that
8468 AC_SUBST provides no portable way to escape literal newlines.
8470 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8471 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8472 Darwin uses -lcrt2.o and there's little point to cataloging all
8473 the system variants. Partial fix reported by Andreas Waechter in:
8474 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
8475 for bug reported by Nelson H. F. Beebe in:

8478 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
8480 * doc/autoconf.texi (AU_DEFUN): Fix English,
8481 suggested by Paul Eggert.
8482 * lib/autoconf/autoupdate.m4: Correct reference to
8483 acobsolete.m4, suggested by Alexandre Duret-Lutz.
8485 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
8487 * bin/autoupdate.in: Define __file__ so that warnings
8488 refer to the correct file.
8489 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
8490 the behavior of the third argument.
8491 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
8492 correctly the behavior of the third argument. Document
8493 what the three macros that AU_DEFUN defines do. Fix
8494 warning message when the third argument includes $0
8495 (reported by Alexandre Duret-Lutz).
8497 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
8498 Eric Sunshine <sunshine@sunshineco.com>
8499 Paul Eggert <eggert@twinsun.com>
8501 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
8502 (AS_INIT): Output shell initialization there. Removed optional
8503 parameter. Expand _AS_SHELL_FN_SPY.
8504 (AS_INIT_WITH_SHELL_FN): Removed.
8505 (_AS_SHELL_FN_SPY): New macro.
8506 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
8507 macros.
8508 (AS_SHELL_SANITIZE): Remove loop to find better shell
8509 and documentation for the parameter.
8510 (_AS_DETECT_BETTER_SHELL): Move it here.
8511 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
8512 (_AS_RUN): Move it here, support testing with eval.
8513 (AS_REQUIRE_SHELL_FN): Require shell functions when
8514 it is used.
8515 (_AS_LINENO_WORKS): Put around braces, we do not
8516 trigger the bash bug anymore.
8517 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
8518 use AS_INIT_WITH_SHELL_FN.
8519 * bin/autoconf.in, tests/wrapper.in: Regenerated.
8521 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
8523 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
8524 * doc/autoconf.texi: Don't say that the third parameter
8525 is broken.
8526 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
8527 (AU_DEFUN): Honor the third parameter, create autoupdate
8528 macros with AU_DEFINE.
8529 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
8530 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
8531 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
8532 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
8533 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

8537 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
8538 * lib/autoconf/status.m4: Remove FIXME.
8539 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
8540 that the macro is not present anymore in the updated
8541 configure.ac.
8542 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
8543 of autoupdate.
8545 2004-01-28 Paul Eggert <eggert@twinsun.com>
8547 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
8548 copyright years.
8549 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8550 2003 (except 1997) to the list of copyright years. This undoes
8551 the 2003-05-22 change, which removed the older years from the list.
8552 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
8554 2004-01-27 Gary V. Vaughan <gary@gnu.org>
8555 Albert Chin-A-Young <china@thewrittenword.com>

8558 grep or ggrep program in PATH that accepts as long lines as
8559 possible.
8560 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
8561 AC_PROG_GREP.
8562 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
8563 egrep and fgrep respectively if $GREP -E/-F don't work.
8564 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
8565 _AC_PROG_GREP, and AC_PROG_SED.
8566 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
8567 longest input length accepted by a command.
8568 (AC_PROG_SED): Use it.
8569 * doc/autoconf.texi (Particular Programs): Document the changes.
8570 * NEWS: Updated.
8572 2004-01-27 Paul Eggert <eggert@twinsun.com>
8574 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

8576 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
8577 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
8579 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
8580 bin/autoconf.in, config/Makefile.in, config/config.guess,
8581 config/config.sub, config/install-sh, config/mdate-sh,

8594 sources.
8596 2004-01-26 Paul Eggert <eggert@twinsun.com>
8598 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8599 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8600 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8601 not <inttypes.h>. Problem reported by Tim Mooney in
8602 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8603 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8604 Likewise.
8606 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8607 otherwise "make check" fails because it forbids cmp (I guess
8608 because cmp treats files as binary on DOS-like systems).
8610 * tests/mktests.sh: Update copyright date to 2004, since some tests
8611 have changed in 2004.
8613 2004-01-23 Gary V. Vaughan <gary@gnu.org>
8615 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
8616 non-truncating sed or gsed program in PATH.
8617 * tests/acprograms.at: Add it.
8618 * doc/autoconf.texi (Particular Programs): Document it.
8619 * NEWS: Updated.
8621 2004-01-15 Paul Eggert <eggert@twinsun.com>
8623 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8624 -std1 disables some useful extensions on Tru64. Problem reported
8625 by N. Lichtmaier in
8626 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
8628 2004-01-14 Paul Eggert <eggert@twinsun.com>
8630 * doc/autoconf.texi (Programming in M4sh): Document that
8631 AS_MKDIR_P succeeds if the destination is a symbolic link
8632 to an existing directory.
8633 (Limitations of Usual Tools): Note that mkdir -p might not
8634 succeed on symlinks to directories.
8636 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
8638 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
8639 * bin/autoheader.in: Grammar fix in message.
8640 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
8641 Test for dir before calling mkdir -p. (trivial changes)
8643 2004-01-13 Eric Blake <ebb9@byu.net>
8645 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
8646 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
8648 2004-01-10 Jim Meyering <jim@meyering.net>
8650 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
8652 2004-01-09 Paul Eggert <eggert@twinsun.com>
8654 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8655 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8656 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8657 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8658 AC_COMPILE_IFELSE, since we now assume our caller invokes
8659 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8660 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8661 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8662 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8664 2004-01-07 Paul Eggert <eggert@twinsun.com>
8666 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8667 `"'...'"`, as it's confusing (and I suspect it may not work on
8668 some platforms). The code was incorrect anyway, as it assumed
8669 that \$ evaluated to itself in that context. Reported by
8670 Alexandre Duret-Lutz.
8672 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
8674 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
8675 and _LT_AC_TAGCONFIG.
8677 2004-01-06 Paul Eggert <eggert@twinsun.com>
8679 * doc/autoconf.texi (One Macro Call): Fix an incorrect
8680 example, and add more examples. Reported by Eric Sunshine.
8682 2004-01-05 Paul Eggert <eggert@twinsun.com>
8684 * doc/autoconf.texi (Limitations of Usual Tools):

9175 AT_help_all.
9176 Instead of making AT_help a sequence of assignments to grow
9177 $at_help_all, just make AT_help_all be the growing contents of
9178 $at_help_all, and make a single assignment in...
9179 (AT_INIT): here.
9180 (at_times_skip): Flip the meaning and rename as...
9181 (at_times_p): this.
9182 (AT_INIT): When summarizing the test that ran, remove
9183 $at_times_file after use, and check it is present before trying to
9184 use it.
9186 2003-09-25 Akim Demaille <akim@epita.fr>
9188 Version 2.57d.
9190 * bin/Makefile.am (edit): Handle '@configure_input@'.
9191 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9192 (ifnames): chmod -w.
9193 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9194 executables, not bin/ executables! Otherwise all the magic needed
9195 to find non installed files is turned off. This caused a failure
9196 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9197 as found in its environment (sent by tests/autoreconf): pointing
9198 to bin/autom4te that could not find its files.
9199 * tests/mktests.sh: Force the replacement of generated files, for
9200 the sake of "mv" program that are interactive when overwriting a
9201 -w file.
9202 * config/install-sh: Upgrade from CVS Automake.
9204 2003-09-23 Paul Eggert <eggert@twinsun.com>

9207 versus test -L issues.
9209 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9210 Paul Eggert <eggert@twinsun.com>
9212 Trivial change to support GCC's configuration procedure.
9213 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
9214 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
9215 about inconsistency if the preprocessor is set to give errors for
9216 any warning.
9217 * doc/autoconf.texi (C Compiler Characteristics): Document this.
9219 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

9232 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
9233 from masters.
9235 2003-09-12 Akim Demaille <akim@epita.fr>
9237 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
9238 not asm/types.h.
9240 2003-09-11 Akim Demaille <akim@epita.fr>
9242 * doc/autoconf.texi (Header Portability): linux/random.h.
9243 From Peter Hendrickson.
9245 2003-09-10 Akim Demaille <akim@epita.fr>
9247 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
9248 willing to edit the output files.
9250 2003-09-10 Akim Demaille <akim@epita.fr>
9252 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
9253 and AC_FC_FREEFORM.
9254 * tests/mktests.sh: Skip AC_FC_SRCEXT.
9255 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
9257 2003-09-09 Akim Demaille <akim@epita.fr>
9259 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
9260 Reported by Gary Vaughan.

9266 trailing files.
9268 2003-09-07 Paul Eggert <eggert@twinsun.com>
9270 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
9271 Improve the accuracy of the wording about obsolescence.
9272 From a suggestion by Ian Lance Taylor in
9273 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
9275 2003-09-05 Paul Eggert <eggert@twinsun.com>
9277 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
9278 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
9280 2003-09-04 Akim Demaille <akim@epita.fr>
9282 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
9283 AC_FUNC_WAIT3.
9285 2003-09-04 Akim Demaille <akim@epita.fr>
9287 * bin/autom4te.in: Use &fatal where more appropriate than &error.
9288 (freeze): When exiting, use $exit_code.
9289 * lib/autoconf/fortran.m4: Comment changes.

9295 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9297 Add support for newer Fortran dialects. The F77 interface is
9298 unchanged, and continues to support Fortran 77. New FC macros
9299 correspond to all the old F77 macros, with output variables FC,
9300 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9301 available dialect, but older dialects can be specified. There are
9302 new macros AC_FC_SRCEXT to set the source extension, and
9303 AC_FC_FREEFORM to accept free-form source files.
9305 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
9306 New macros.
9307 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
9308 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

9310 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

9323 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
9324 Rewrite in terms of the above.
9325 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
9326 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
9327 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
9328 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
9330 2003-09-02 Paul Eggert <eggert@twinsun.com>
9332 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
9333 Document problems with timestamp resolution that 'make', 'cp -p', and
9334 'touch -r' have.
9336 2003-08-27 Akim Demaille <akim@epita.fr>
9338 * tests/m4sugar.at (cross_warning): Make sure to enable the
9339 output, so that we can track spurious m4sugar output.
9340 * tests/local.at: Require 2.57.
9341 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9342 are defaulted by AT_CHECK anyway.
9343 Use AT_CHECK_AUTOM4TE.
9344 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
9345 missing dnl.
9347 2003-08-27 Akim Demaille <akim@epita.fr>
9349 * bin/autoheader.in: Issue the "Using auxiliary..." message only
9350 when -Wobsolete is set.
9351 Set it on by default.
9352 Suggested by Klee Dienes.

9396 2003-08-22 Akim Demaille <akim@epita.fr>
9398 Output stack traces in warnings.
9400 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
9401 Replace the former...
9402 (m4_warn): Pass the call stack to _m4_warn.
9403 * bin/autom4te.in: Adjust to output the call stack.
9404 * tests/m4sugar.at (m4@&t@_warn): Adjust.
9406 2003-08-22 Akim Demaille <akim@epita.fr>
9408 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
9409 * bin/autom4te.in: Adjust.
9411 2003-08-21 Akim Demaille <akim@epita.fr>
9413 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
9414 (&verbose): Remove.
9415 (&getopt): Adjust the note and verb channels, depending upon
9416 --verbose.
9417 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
9418 * bin/autoupdate.in: Adjust.
9419 Use &verb, not &verbose.
9421 2003-08-21 Akim Demaille <akim@epita.fr>
9423 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9424 &parse_WARNINGS.
9425 ($help): Use Autom4te::ChannelDefs::usage.
9426 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9427 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9429 2003-08-21 Akim Demaille <akim@epita.fr>
9431 First stab at preserving warnings between calls to autom4te,
9432 including when the cache is used.
9434 There are still several issues: (i) there are too many runs of m4
9435 (one for include, one for warnings, and some more), (ii) warnings
9436 spreading on several lines are not handled gracefully, (iii) the
9437 code meant to have the call stack display for errors does not work
9438 (its handling should move from m4 to autom4te).
9440 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9441 Use them.
9442 (@preselect): Add m4_warn.
9443 ($exit_status): Remove, use $exit_code.
9444 ($help): Use Autom4te::ChannelDefs::usage.
9445 (&handle_m4): No longer define the m4_warnings.
9446 At each run, extract and report the warnings.
9447 Always cache the result, including if the exit status is on
9448 failure, since if nothing changes, we should result in the same
9449 failure, hence we can use the cache.
9450 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9451 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9452 Remove.
9453 (m4_warn): Redefine as a do-nothing: it is its invocation that
9454 matters, as warnings are now reported via traces.
9455 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9456 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9457 the latter reveals calls to the former.
9459 Adjust the tests.
9461 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9463 2003-08-21 Akim Demaille <akim@epita.fr>
9465 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
9466 Use them.
9468 2003-08-21 Akim Demaille <akim@epita.fr>
9470 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
9471 forward order.
9472 * lib/Autom4te/ChannelDefs.pm: Doc typos.
9473 (&parse_warnings): Accept a list of warning requests.
9474 (&usage): Return a string, not a side effect.
9475 (cross): New warning category.
9477 2003-08-21 Akim Demaille <akim@epita.fr>
9479 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
9480 (&require_configure_ac): Accept an optional directory argument.
9481 ($configure_ac): Remove.
9482 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
9483 (&catfile): Remove.
9484 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
9485 * bin/autoscan.in: Adjust.
9487 2003-08-20 Akim Demaille <akim@epita.fr>
9489 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9490 Reported by Alexandre Duret-Lutz.
9492 2003-08-20 Akim Demaille <akim@epita.fr>
9494 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9495 * bin/autom4te: Adjust.
9496 In particular, be Autoconf tools are really silent when properly
9497 working, bind the verbosity of the 'note' channel to $verbose.
9498 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9499 (&xsystem, &contents): Remove, since they are exported by...
9500 * lib/Autom4te/FileUtils.pm: this.
9501 More perldoc.
9502 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
9503 * lib/Autom4te/FileUtils.pm: here.
9505 2003-08-20 Akim Demaille <akim@epita.fr>
9507 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
9508 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
9509 from CVS Automake.
9511 2003-08-20 Akim Demaille <akim@epita.fr>

9514 (autom4te-update): New.
9515 * Makefile.cfg (update): Bind autom4te-update.
9517 2003-08-19 Derek Price <derek@ximbiot.com>
9519 * lib/autotest/general.m4: Comment various HELP_* diversions.
9520 (PARSE_ARGS_BEGIN): New section for option parsing related

9529 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
9531 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
9533 * lib/autom4te.in (Automake-preselections): Preselect
9534 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
9535 and m4_sinclude.
9537 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
9539 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
9540 (Autoconf-without-aclocal-m4): ... this new language.
9541 * doc/autoconf.texi (autom4te Invocation): Mention
9542 Autoconf-without-aclocal-m4.

9558 2003-08-14 Derek Price <derek@ximbiot.com>
9560 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
9561 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9562 shorter column three. Add DESCRIPTION to log file content.
9564 2003-08-13 Derek Price <derek@ximbiot.com>
9566 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
9567 output.
9569 2003-08-12 Derek Price <derek@ximbiot.com>
9571 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
9572 (AT_CHECK_NOESCAPE): Move core functionality to...
9573 (_AT_CHECK): ...this new macro.
9575 2003-08-07 Derek Price <derek@ximbiot.com>
9577 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
9578 (AT_CHECK_NOESCAPE): ...to this new macro.
9580 2003-07-31 Paul Eggert <eggert@twinsun.com>
9582 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
9583 in Bash 2.01. Problem reported by Brian Gough in
9584 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
9586 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
9588 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
9589 -lcrt1.o, for OS X. (trivial change)
9591 2003-07-07 Paul Eggert <eggert@twinsun.com>
9593 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
9594 inside '#ifndef __cplusplus'. Problem reported by
9595 Bob Friesenhahn.
9597 2003-07-06 Bill Clarke <llib@computer.org>
9599 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
9600 'long', not 'int', for benefit of Sun's recent C++ compilers
9601 (trivial change). See:
9602 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
9603 (This really should be 'intptr_t', not 'long', but that would
9604 take more work.)
9606 2003-06-25 Akim Demaille <akim@epita.fr>
9608 * lib/Makefile.am (autom4te.cfg): Make it read only.
9609 Depend on Makefile since it contains substitutions.
9610 From Paolo Bonzini.

9612 This change was made on autom4te.cfg which is generated.
9613 Reported by Raja R. Harinath.
9615 2003-06-25 Akim Demaille <akim@epita.fr>
9617 * doc/autoconf.texi (Header Portability): sys/mount.h.
9618 From Gareth McCaughan.
9620 2003-06-23 Akim Demaille <akim@epita.fr>
9622 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9623 not all of them. This fixes 1. the fact that when testing
9624 Autoconf there are many many config.log, 2. the incorrect use of
9625 top_srcdir to find config.log.
9626 Don't mix the detailed output of failed test with the summary of
9627 failures. Rather, append detailed log afterwards.
9629 2003-06-23 Akim Demaille <akim@epita.fr>
9631 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
9632 always run: output config.log on $at_group_log.
9634 2003-06-23 Akim Demaille <akim@epita.fr>
9636 * tests/torture.at (#define header templates): Don't use quotes in

9642 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
9643 * tests/atspecific.m4: Rename as...
9644 * tests/local.at: This.
9645 * tests/suite.at: Move the globals into...
9646 * tests/local.at: here.
9647 * tests/Makefile.am: Adjust.
9648 * doc/autoconf.texi (testsuite Scripts): Adjust.
9650 2003-06-21 Kevin Ryde <user42@zip.com.au>
9652 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
9653 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
9654 ensuring we add -std1 for full-ANSI.
9656 * doc/autoconf.texi (hdrindex): New macro.

9699 PODify.
9701 2003-05-28 Paul Eggert <eggert@twinsun.com>
9703 * NEWS, doc/autoconf.texi (Particular Functions),
9704 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
9705 is the inverse of localtime.
9707 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>

9714 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9716 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
9717 Do not call `_exit()', simply modify `$?'.
9718 (xsystem): Reset $! before running system, and check it afterward.
9719 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
9720 63 for version mismatches.
9722 2003-05-23 Akim Demaille <akim@epita.fr>
9724 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9725 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9726 the middle of a line).
9727 * lib/m4sugar/m4sugar.m4: Likewise.
9728 Remove useless spaces in comments.
9730 2003-05-23 Akim Demaille <akim@epita.fr>
9732 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
9733 exit 63, so that we (or Automake's "missing") can tell the
9734 difference with a plain failure.
9735 * doc/autoconf.texi (Notices): Adjust.
9737 2003-05-23 Akim Demaille <akim@epita.fr>

9744 Paul Eggert <eggert@twinsun.com>
9746 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9747 Remove `#include <stdlib.h>' from the list; we should never
9748 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9749 resulting namespace pollution would cause other tests to fail.
9750 Configure scripts run with some older versions of g++ and HP's
9751 aCC would fail due to such an #include. Problems reported by
9752 Matthew Mueller in <http://bugs.debian.org/120704> and by
9753 Keith Bostic in
9754 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9755 In the test, use the test declaration before including <stdlib.h>,
9756 as that's closer to how it'll be used.
9758 2003-05-23 Akim Demaille <akim@epita.fr>
9760 * doc/autoconf.texi (Header Portability): ucred.h.
9761 From Ian Redfern.
9763 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9765 Overhaul Autotest's logging: generate separate log files
9766 in testsuite.dir/NNN/testsuite.log, and append them to
9767 testsuite.log instead of re-running the test verbosely.
9769 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9770 file descriptor, write 0 to at_status_file instead of setting
9771 at_status=0, initialize some new variables (at_status_file,
9772 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9773 to rerun the tests, instead append the at_group_log to the
9774 at_suite_log when a test fails.
9775 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9776 with the AS_MESSAGE_LOG_FD redirected to stdout.
9777 (AT_CLEANUP): save the output status in $at_status_file
9778 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9779 its original place.
9780 (AT_CHECK): since tests are run with a redirected stdout,
9781 and used to be re-run in verbose mode, turn some $at_verbose
9782 into echo, and don't redirect the output of testing stdout
9783 and stderr.
9785 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9786 the name of the debugging directory and information about
9787 its contents.
9789 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9791 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
9792 parameter.

9904 and truncate.
9906 2003-05-06 Akim Demaille <akim@epita.fr>
9908 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9909 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9910 by aclocal.m4 is changed it might require the importing of another
9911 m4 extension file, i.e., aclocal must be run.
9913 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9914 (&parse_args): Use --force with aclocal if required and supported.

9922 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9923 argument instead of a file name, so that the request file remains
9924 open during the whole autom4te run.
9925 ($icache_file): New.
9926 (&freeze): Lock the $icache_file.
9928 2003-04-29 Derek Price <derek@ximbiot.com>
9930 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9931 seperator with m4_append_uniq(). It doesn't work.
9932 (AT_CLEANUP): Add `;' to end of at_help_all.
9933 (AT_INIT): Allow --keywords to be specified more than once. When
9934 grepping $at_help_all for keywords, use the field and keyword
9935 seperators to ensure a complete keyword match. Alter at_prev handling
9936 to support the new --keywords behavior.
9938 2003-04-27 Karl Berry <karl@freefriends.org>
9940 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9941 align better with others. I also made some of the individual
9942 entries on one line, for brevity and to make it easier for me to
9943 sort my dir-example file in the Texinfo distribution :).
9945 2003-04-12 Jim Meyering <jim@meyering.net>

10010 header causes problems.
10012 2003-03-28 Akim Demaille <akim@epita.fr>
10014 * tests/torture.at (Configuring subdirectories): Require aclocal
10015 1.4, otherwise the test fails, as it does support configure.ac.
10016 This fixes the "test 40 failed" bug reports.
10018 2003-03-28 Akim Demaille <akim@epita.fr>
10020 * doc/autoconf.texi (C Compiler): `#line' portability.

10089 (Automake): Automake 1.5+ no longer requires special tools to be
10090 present on the developer's host.

10135 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10136 format starting with "-".
10138 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10140 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10141 is not portable inside Makefile.
10143 2003-02-20 Akim Demaille <akim@epita.fr>
10145 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10146 compiler says yeah, but preproc says nope, compiler is right.
10147 Conversely, prompt the reader to send a bug report to the
10148 maintainers of the package, not of Autoconf.
10150 2003-02-20 Klee Dienes <kdienes@apple.com>
10152 * bin/autoreconf.in (autoreconf_current_directory): Properly
10153 handle an empty aclocal.m4.

10159 From Larry Jones.
10161 2002-12-23 Paul Eggert <eggert@twinsun.com>
10163 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10164 innocuous variant befor including <limits.h> or <assert.h>. This
10165 works around a bug reported by Albert Chin: HP-UX 11i
10166 (and earlier versions) have a <limits.h> that declares
10167 gettimeofday and many other functions.
10169 2002-12-03 Paul Eggert <eggert@twinsun.com>
10171 Version 2.57.
10173 * NEWS, configure.ac: Update version.
10175 * doc/fdl.texi: Upgrade to FDL version 1.2.
10177 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10178 nontrivially in main's body, so that f's external declaration is
10179 not optimized away in AIX. This should fix the bug reported by
10180 Martin Frydl in
10181 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10183 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10184 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10185 defined, to support freestanding compilers. This should fix the
10186 bug reported by Momchil Velkov in
10187 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10189 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10190 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10191 obsolete AC_CHECK_TYPE. The missing empty arg was reported
10192 by Simon Josefsson in
10193 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
10195 * Makefile.maint (www-gnu): New macro.
10196 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
10197 the location has moved.
10199 2002-12-02 Martin Frydl <martin@systinet.com>
10201 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
10202 \(.*\) match is too long and there is something more to be checked.
10203 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
10205 2002-11-15 Akim Demaille <akim@epita.fr>
10207 Version 2.56.
10209 * config/install-sh: chmod +x.
10210 From Paul Eggert.
10211 * config/move-if-change: Indenting changes.
10212 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
10213 * configure.ac (AM_INIT_AUTOMAKE): here.
10214 Require 1.7.1.
10216 2002-11-14 Akim Demaille <akim@epita.fr>
10218 Version 2.55.
10220 * config/config.guess, config/config.sub, config/install-sh:
10221 Update from masters.
10223 2002-11-14 Akim Demaille <akim@epita.fr>
10225 * Makefile.maint: Sync with Bison, i.e.:
10226 (po-check): Scan .l and .y files instead of the
10227 .c and the .h files that they generate. This fixes the bug
10228 reported by Tim Van Holder in:
10229 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10230 Look for N_ as well as for _. Try to avoid matching #define for
10231 N_ and _.
10232 From Paul Eggert.
10234 2002-11-14 Akim Demaille <akim@epita.fr>
10236 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10237 From Paul Eggert and Albert Chin-A-Young.
10239 2002-11-14 Akim Demaille <akim@epita.fr>
10241 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10242 From Paul Eggert and Albert Chin-A-Young.
10244 2002-11-14 Kevin Ryde <user42@zip.com.au>
10246 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10247 than assigning in main, to avoid HP cc +O3 optimizing it away.
10249 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10251 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10252 option. Process --recheck after parsing all options. Pass -q
10253 option to configure on --recheck.
10254 (AC_OUTPUT): Pass -q from configure to config.status.
10255 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10256 arguments to record.
10257 * doc/autoconf.texi (config.status Invocation): Document
10258 config.status -q option.
10260 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10262 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10263 Makefile.in if Makefile.am exists.
10264 (output): Strip `.am' from Makefiles. Don't
10265 output AC_CONFIG_FILES if no Makefiles were found.
10267 2002-11-07 Akim Demaille <akim@epita.fr>
10269 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

10272 (local_updates): New.
10274 2002-11-06 Akim Demaille <akim@epita.fr>
10276 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
10277 declaration in extern "C" too.
10278 Reported by Roberto Bagnara.
10280 2002-11-06 Akim Demaille <akim@epita.fr>
10282 * tests/torture.at (Configuring subdirectories): Don't use grep
10283 -w.
10284 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
10285 Reported by Ezra Peisach.
10287 2002-11-05 Akim Demaille <akim@epita.fr>
10289 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10290 Remove.
10291 We _have_ to stop using the old compatibility scheme that tried to
10292 avoid useless backslashes because Libtool 1.4.3 contains a
10293 AC_DEFINE([error_t], [int],
10294 [Define to a type to use for \`error_t' if it is not
10295 otherwise available.])
10296 We _have_ to quote the single quote and backslashes with \. The
10297 old compatibility scheme saw that ` was backslashed, and therefore
10298 did not quote the single quote. Hence before this patch, Autoconf
10299 was not compatible with Libtool.
10301 2002-11-04 Paul Eggert <eggert@twinsun.com>
10303 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
10304 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
10305 LC_NAME, LC_PAPER, LC_TELEPHONE.

10308 2002-11-04 Akim Demaille <akim@epita.fr>
10310 Version 2.54c.
10312 * Makefile.maint (update, cvs-update, po-update, do-po-update):
10313 New.
10314 * config/texinfo.tex: Update.
10316 2002-11-03 Akim Demaille <akim@epita.fr>
10318 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
10319 from...
10320 (&autoreconf): here.
10321 ($help, $make, &parse_args, &autoreconf_current_directory):
10322 Support -m/--make.

10331 to ac_cv_func_realloc_0_nonnull.
10332 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
10334 2002-10-31 Akim Demaille <akim@epita.fr>
10336 The test suite was no longer checking for trailing envvars and files.
10338 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
10339 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
10341 2002-10-31 Akim Demaille <akim@epita.fr>
10343 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
10344 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10345 Make variable, not a shell variable.
10346 Suggested by Bruno Haible.
10348 2002-10-31 Akim Demaille <akim@epita.fr>
10350 * bin/autom4te.in (load_configuration): Reject #args out of any
10351 language.

10369 2002-10-29 Paul Eggert <eggert@twinsun.com>
10371 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
10372 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
10373 Problem reported by Bruno Haible.
10375 2002-10-29 Akim Demaille <akim@epita.fr>
10377 * doc/autoconf.texi (Header Templates): Put also in words what the
10378 pictures says to assist free style readers.

10397 * tests/torture.at (Deep Package): New test.

10615 From Art Haas.
10617 2002-10-22 Akim Demaille <akim@epita.fr>
10619 Restore the 2002-10-11 Akim Demaille <akim@epita.fr> patch:

10628 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
10629 words about HP-UX cmp: it was actually a user-written cmp.
10631 2002-10-22 Akim Demaille <akim@epita.fr>
10633 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
10634 are a few warnings.
10635 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
10636 Quote for Perl '' strings, not "".
10637 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
10638 strings.
10640 2002-10-22 Akim Demaille <akim@epita.fr>
10642 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
10643 characters is a syntax warning now.
10644 (_AS_QUOTE): Accept $2 as list of characters to quote.
10645 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
10646 Quote for Perl, not sh.
10647 * bin/autoheader.in: When $debug, report the file which is
10648 `do'ne.
10649 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
10650 `@', to tickle Perl's lists.
10651 Reported by Carlos Velasco.
10653 2002-10-18 Akim Demaille <akim@epita.fr>
10655 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
10656 missing included files _are_ errors.
10657 Thanks to Alexandre Duret-Lutz.
10658 * tests/tools.at (autom4te cache): Adjust.
10659 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

10667 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
10668 Fixes the `AC_ARG_VAR' test failures.
10669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
10670 * lib/freeze.mk (check-forbidden-patterns): New.
10671 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
10672 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
10673 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
10674 /dev/null.
10675 Reported months ago by H. Merijn Brand.
10677 2002-10-17 Akim Demaille <akim@epita.fr>

10681 2002-10-16 Paul Eggert <eggert@twinsun.com>
10683 * Makefile.maint (wget_files): Remove ansi2knr.c.
10684 (ansi2knr.c-url_prefix): Remove.
10686 2002-10-16 Akim Demaille <akim@epita.fr>
10688 Because of caching, some files that no longer exist and are no
10689 longer required can still cause errors.
10690 Reported by Alexandre Duret-Lutz.
10692 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
10693 to frozen files in @ARGV, as @ARGV must remain being a list of
10694 files. Rather, at M4 call sites, use this...
10695 (&files_to_options): New function.
10696 (&freeze): Use &error.
10697 (&up_to_date): If a file that was included according to the cache
10698 is no longer there, then the output is out dated.
10699 (&main): Don't even check whether a file is up to date is anyway
10700 --force is given.
10701 * tests/tools.at (autom4te cache): New.
10703 2002-10-16 Akim Demaille <akim@epita.fr>
10705 * bin/autoconf.as: Kill dead options.
10706 * bin/autoupdate.in (&parse_args): Kill old options.
10707 * bin/autoreconf.in (&parse_args): Remove dead options.
10708 Factor some code.
10709 (&autoreconf): Report the directories we enter *and leave*, so
10710 that error messages can be easily located, and use GNU Make
10711 format, so that Emacs' compile mode understands us.
10712 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
10713 if some file was changed instead of `print'.
10714 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
10715 (&parse_args): Remove the dead options.
10716 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
10717 autoheader's quiet mode.

10722 2002-10-11 Akim Demaille <akim@epita.fr>
10724 No longer use CPP to check for the existing of headers: use CC to
10725 check for compilability.
10727 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
10728 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

10730 (AC_CHECK_HEADER): this.
10732 * lib/autotest/general.m4 (AT_INIT): Include the failed test
10733 numbers in the Subject suggestion.
10735 2002-10-11 Akim Demaille <akim@epita.fr>
10737 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.

10740 2002-10-11 Akim Demaille <akim@epita.fr>
10742 * tests/torture.at (AC_ARG_VAR): Have configure report the value
10743 of `precious'.
10745 2002-10-11 Akim Demaille <akim@epita.fr>
10747 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
10748 file name to enable parallel executions.
10749 From Sam Varshavchik.
10751 2002-10-08 Akim Demaille <akim@epita.fr>
10753 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10754 aclocal invocation, as Gettext macros might not be visible to
10755 aclocal.
10756 Instead of blindly running autopoint, scan configure.ac (not the
10757 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10758 Reported by Paul D. Smith.
10760 2002-10-08 Paul Eggert <eggert@twinsun.com>
10762 Work around problems found when POSIXLY_CORRECT=1 is set.
10763 None of this seems to have anything to do with POSIX, really,
10764 but it's how Perl getopt works.
10765 * bin/autom4te.in (parse_args): Configure GetOpt with
10766 "permute", too.
10767 * doc/autoconf.texi (Invoking autom4te):
10768 --warning -> --warnings.
10769 * lib/autom4te.in: --warning -> --warnings.
10771 2002-09-28 Akim Demaille <akim@epita.fr>
10773 * doc/autoconf.texi (autom4te.cache): New section.

10788 2002-09-28 Akim Demaille <akim@epita.fr>
10790 * tests/torture.at (Configuring subdirectories): Be robust to
10791 users who use config.site to require for a cache: in this case,
10792 the two last configure runs, using two different sets of
10793 arguments, trigger a legitimate error.
10795 2002-09-28 Akim Demaille <akim@epita.fr>
10797 * tests/m4sh.at (Functions Support, Functions and return Support):
10798 New.

10805 (autom4te): Specify that the sources are in the $srcdir.
10806 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10808 2002-09-28 Akim Demaille <akim@epita.fr>
10810 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
10811 (tm_zone): Move their rules to...
10812 * lib/autoconf/types.m4: here, using AN_ macros.
10813 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10814 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
10815 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
10816 * lib/autoconf/programs.m4: here.

10819 Use it.

10823 * lib/autoconf/autoscan.m4: New file.
10824 * lib/autoconf/autoconf.m4: Include it.
10825 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
10826 that were listed in the original autoscan.list.
10827 * lib/autoconf/headers.m4: Similarly with headers.
10828 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10829 (.m4.m4f): Don't pass --prepend-include, since that's done by
10830 tests/autom4te itself.
10831 * lib/autoscan/Makefile.am: Include freeze.mk.
10832 (autoscan.list): New target --this file is no longer a source.
10833 (autoscan.pre): New file.
10835 2002-09-28 Akim Demaille <akim@epita.fr>
10837 * bin/autoscan.in (@kinds): Make them singular.
10838 Adjust all uses.
10839 (&init_tables): When --debug, report the list of rules to ease
10840 tracking changes in autoscan.list.
10841 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10843 2002-09-28 Akim Demaille <akim@epita.fr>
10845 * lib/autoscan/functions, lib/autoscan/headers,
10846 * lib/autoscan/identifiers, lib/autoscan/makevars,
10847 * lib/autoscan/programs: Merge into...
10848 * lib/autoscan/autoscan.list: this.
10849 * bin/autoscan.in (&init_tables): Adjust.
10851 2002-09-28 Akim Demaille <akim@epita.fr>
10853 * lib/autoscan/functions, lib/autoscan/headers,
10854 * lib/autoscan/identifiers, lib/autoscan/makevars,
10855 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10856 `functions' line is now prefixed with `function:'.
10857 * bin/autoscan.in (&init_tables): Adjust.
10859 2002-09-28 Akim Demaille <akim@epita.fr>
10861 From now on, autoscan files must always map a macro name to a
10862 word: there is no `default' macro for autoscan.
10864 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10865 all.
10866 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10867 explicit.
10869 2002-09-28 Akim Demaille <akim@epita.fr>
10871 * bin/autoscan.in (%c_keywords): Remove.
10872 (&used): Keep only track of the words we might be interested in.

10874 checks.

10898 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
10899 (getwd): Trigger a warning.
10901 2002-09-26 Akim Demaille <akim@epita.fr>
10903 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10904 Reported by Ralf Corsepius.
10905 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10907 2002-09-26 Akim Demaille <akim@epita.fr>
10909 Single suffix rules and seperated dependencies are not portable.

10913 Separated Dependencies'.
10914 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10915 (ifnames, autoscan, autom4te): Un-factor into several rules.
10917 2002-09-25 Paul Eggert <eggert@twinsun.com>
10919 * BUGS (Interoperability bugs): New section. Mention libtool
10920 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10922 2002-09-24 Paul Eggert <eggert@twinsun.com>

10956 reading config.log when the compiler is rejected.
10957 Suggested by Guido Draheim.
10959 2002-09-13 Akim Demaille <akim@epita.fr>
10961 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10962 (chdir_init) might hang when stat'ing mounted directories.
10963 Reported by Vance Shipley.
10965 2002-09-12 Akim Demaille <akim@epita.fr>
10967 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10968 the lists.
10970 2002-09-12 Akim Demaille <akim@epita.fr>
10972 * doc/autoconf.texi (Defining Symbols): Present two different
10973 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

10978 * doc/autoconf.texi: Review grammar and punctuation.

10982 * doc/autoconf.texi: Fix minor formatting, spelling, and
10983 grammatical typos.
10984 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10985 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10986 is obsolescent.
10988 2002-09-11 Akim Demaille <akim@epita.fr>
10990 * doc/autoconf.texi (Questions): Rename as...
10991 (FAQ): this.

11002 plain `@' is wanted.
11004 2002-09-09 Akim Demaille <akim@epita.fr>
11006 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11007 `duplicates', since the algorithm was too naive and could keep
11008 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11009 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11010 Reported by Ralf Corsepius.
11011 * tests/torture.at (Configuring subdirectories): Exercise these
11012 cases.
11014 2002-09-09 Akim Demaille <akim@epita.fr>
11016 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when

11032 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11033 (ifnames, autoscan, autom4te): Since we don't only depend on
11034 configure.ac variables (such as VERSION etc.), but also on prefix
11035 and so forth, depend on Makefile, not configure.ac.
11036 Reported by Alexandre Duret-Lutz.
11037 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11039 2002-09-05 Kevin Ryde <user42@zip.com.au>
11041 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11042 doesn't seem to be confined to ia64, just say "some versions".
11044 2002-09-04 Akim Demaille <akim@epita.fr>
11046 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11047 Automake 1.6c.
11048 * Makefile.am (maintainer-clean-local): Remove.
11049 (MAINTAINERCLEANFILES): Remove COPYING.

11059 * configure.ac: Bump to 2.53d.
11060 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11061 as of today, on Automake's team suggestion.
11063 2002-09-03 Akim Demaille <akim@epita.fr>
11065 Version 2.53c.
11067 2002-09-02 Akim Demaille <akim@epita.fr>

11075 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11076 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11077 Also, tweak grammar: s/make sure to/be sure to/.
11079 2002-09-02 Paul Eggert <eggert@twinsun.com>
11081 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11082 directory names are generally preferable to physical names.
11084 2002-09-02 Akim Demaille <akim@epita.fr>
11086 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11087 Reported by Raja R. Harinath.
11088 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11089 * bin/autoupdate.in: Use error instead of die.
11091 2002-09-01 Paul Eggert <eggert@twinsun.com>
11093 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11094 ordinary shell concatenation rather than echo+tr+sed command that
11095 runs afoul of a long-line-related sed bug in Solaris 8.
11097 * bin/autoheader.in (parse_args): --warning -> --warnings.
11099 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11100 stdout, as traditional "ls" does.
11101 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11102 _AC_COMPILER_EXEEXT_O): Likewise.
11103 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11105 * bin/autoconf.as: Add --prepend-include option. This patch was
11106 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11107 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11109 * bin/autoconf.in, configure: Regenerate.
11111 * doc/autoconf.texi (Special Shell Variables): Mention
11112 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11114 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11115 MAILPATH and set PS1, PS2, PS4 to default values, to work
11116 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11117 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11118 the Autoconf documentation specifies; fall back to "unset" only if
11119 this fails. Use a shell for-loop for this rather than an m4 loop,
11120 to shorten the output script.
11122 2002-08-30 Paul Eggert <eggert@twinsun.com>
11124 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11125 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11126 for the CDPATH problem. Document PWD.
11127 (Limitations of Builtins): Document the problem that "cd $foo" and
11128 "ls $foo" may refer to different directories in shells conforming
11129 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11130 example, since the old example is now out of date.
11132 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11133 FOO" and "ls FOO" talk about different directories; this catches
11134 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11135 spaghetti.
11137 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11138 of rolling our own unset.
11139 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11140 in practice we needn't worry about CDPATH if unset doesn't work.
11142 * Makefile.in, aclocal.m4, bin/Makefile.in,
11143 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11144 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11145 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11146 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11147 tests/Makefile.in: Regenerate with Automake 1.6.3.
11149 * config/config.guess, config/config.sub, config/mkinstalldirs:
11150 Update.
11152 * configure: Regenerate with self.
11154 2002-08-30 Kevin Ryde <user42@zip.com.au>
11156 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11157 default output.
11159 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11161 * bin/autom4te.in (Request::load): Correctly test for "do" read
11162 failure.
11164 2002-08-29 Akim Demaille <akim@epita.fr>
11166 * lib/Autom4te/General.pm (&xqx): New.
11167 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11168 hand, which is not portable.
11169 (&error): New.
11170 * bin/autom4te.in: Use them.
11171 Use &error instead of die.
11172 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11173 Adjust.
11175 2002-08-17 Paul Eggert <eggert@twinsun.com>
11177 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11178 default list of compilers to try, since it was long ago superseded
11179 by the ksh fc builtin. Suggested by Steven G. Johnson.
11181 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11183 * doc/autoconf.texi (Invoking autom4te): End the option table,
11184 fixing a bug introduced by the previous patch.
11185 (Limitations of Make): Add a 'target lookup' subentry in the
11186 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11188 2002-07-29 Mark D. Roth <roth@feep.net>
11190 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11191 options and use $AUTOM4TE_PATH.
11192 * doc/autoconf.texi: Remove documentation of autom4te
11193 --include-envvar and --site-macro-subdir options and document
11194 use of $AUTOM4TE_PATH.
11195 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11196 arguments from each language section.
11198 2002-07-29 Paul Eggert <eggert@twinsun.com>
11200 * doc/install.texi: Include copyright symbol in copyright notice.
11202 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11203 Replace with:
11204 (AM_MAKEINFOFLAGS): New macro.
11205 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11206 * Makefile.am (INSTALL): Use the new macros.
11207 Use -o rather than --output, since "missing" does not grok --output.
11209 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11211 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11212 comments do not always work. Never trust the exit status of
11213 `make -k'.
11215 2002-07-24 Kevin Ryde <user42@zip.com.au>
11217 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11218 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11220 2002-07-23 Paul Eggert <eggert@twinsun.com>
11222 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11223 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11224 apparently treats PATH="nonexistent" as if it contained ".".
11225 Bug reported by Stefan `Sec' Zehl.
11227 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11229 * doc/autoconf.texi (Limitations of Make): Mention the special
11230 handling of the obj/ directory by BSD make.

11242 2002-07-19 Akim Demaille <akim@epita.fr>
11244 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
11246 2002-07-18 Akim Demaille <akim@epita.fr>
11248 Version 2.53b.
11250 2002-07-18 Akim Demaille <akim@epita.fr>
11252 * config/config.guess, config/config.sub: Update.
11254 2002-07-18 Akim Demaille <akim@epita.fr>
11256 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
11257 Automake's parts.

11277 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
11278 latter was not run.

11282 * lib/Autom4te/General.pm (find_file): Browse the directories in
11283 the order they are given.

11344 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
11346 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
11347 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

11349 so that Emacs setups GNU style for perl-mode and cperl-mode.
11351 2002-06-27 Paul Eggert <eggert@twinsun.com>
11353 * config/install-sh: Quote $src. Prefer || to test's -o option,
11354 as per "Limitations of Builtins".
11355 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
11356 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11358 * tests/mktests.sh: Use grep instead of fgrep, as per
11359 "Limitations of Builtins".
11361 2002-06-15 Paul Eggert <eggert@twinsun.com>
11363 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
11364 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
11365 so that we consistently test the just-built programs.
11366 * tests/wrappl.as: Likewise.
11368 2002-06-12 Paul Eggert <eggert@twinsun.com>
11370 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
11371 name, so that symlinks to 'autoconf' work properly. Bug reported
11372 by Bruno Haible.
11373 * bin/autoheader.in (AUTOM4TE): Likewise.
11374 * bin/autoreconf.in (autoconf, autoheader): Likewise.
11375 * bin/autoscan.in (autom4te): Likewise.
11376 * bin/autoupdate.in (autom4te): Likewise.
11378 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
11379 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
11380 on Solaris 2.5.1.
11382 2002-06-11 Andreas Schwab <schwab@suse.de>
11384 * doc/autoconf.texi: Add more dir entries.
11386 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
11388 * bin/autom4te.in ($cache): Don't define using `$me', the name
11389 of the cache should not depend on the name under which autom4te
11390 was installed.
11392 2002-06-07 Akim Demaille <akim@epita.fr>
11394 * tests/tools.at (autoconf: forbidden tokens, basic)
11395 (autoconf: forbidden tokens, exceptions): Adjust to the change of
11396 words in autom4te.in.
11398 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

11407 (AC_REPLACE_FNMATCH): this.
11408 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
11409 AC_FUNC_FNMATCH_GNU.
11411 2002-06-07 Akim Demaille <akim@epita.fr>
11413 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
11414 Rosetta Stone for Unix.
11416 2002-06-07 Akim Demaille <akim@epita.fr>
11418 * bin/autom4te.in (warn_forbidden): When rejecting a token,
11419 suggest m4_pattern_allow.
11420 Suggested by Adam J. Richter.
11422 2002-06-07 Akim Demaille <akim@epita.fr>
11424 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
11425 ac_config_libobj_dir.
11426 (AC_CONFIG_LIBOBJ_DIR): New.
11427 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
11428 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
11429 Use ac_config_libobj_dir to find the replacement files.
11430 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
11431 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
11432 (AC_REPLACE_FNMATCH_GNU): these.
11433 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
11434 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
11435 * tests/mktests.sh (ac_exclude_list): Don't check
11436 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
11438 2002-06-06 Paul Eggert <eggert@twinsun.com>
11440 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
11441 if ln doesn't work.
11442 * NEWS: Likewise.
11443 * doc/autoconf.texi (Configuration Links): Likewise.
11444 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
11446 2002-06-05 Paul Eggert <eggert@twinsun.com>
11448 * config/config.guess, config/config.sub, config/texinfo.tex:
11449 Update from masters.
11451 2002-05-29 Paul Eggert <eggert@twinsun.com>
11453 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

11466 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
11467 * doc/autoconf.texi (Particular Programs): Document them.
11468 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
11469 * NEWS: Likewise.
11471 2002-05-27 Paul Eggert <eggert@twinsun.com>
11473 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
11474 * NEWS, doc/autoconf.texi (Particular Types): Document it.
11475 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
11476 instead of AC_MBSTATE_T, which never existed.
11478 2002-05-23 Akim Demaille <akim@epita.fr>
11480 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
11481 version of Autoconf that is discussed.
11483 2002-05-22 Paul Eggert <eggert@twinsun.com>
11485 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
11486 from the default list of compilers to try. Suggested by
11487 Kate Hedstrom.
11488 * NEWS: Document the above.
11489 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
11491 2002-05-17 Paul Eggert <eggert@twinsun.com>
11493 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
11494 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
11495 This improves on an earlier suggestion by H. Peter Anvin.
11497 2002-05-16 Paul Eggert <eggert@twinsun.com>
11499 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11500 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11501 Both macros now accept an optional source-dir arg.
11502 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11504 * NEWS: Document this.
11505 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11507 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11508 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11509 not for GNU extensions; this undoes part of the 2000-11-03 change,
11510 reverting to 2.13-compatible behavior.
11511 Add new optional argument DIR.
11512 (AC_FUNC_FNMATCH_GNU): New macro.
11514 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11516 2002-05-08 Paul Eggert <eggert@twinsun.com>
11518 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11519 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11520 and it causes a 'test' syntax error if it fails.
11521 Bug reported by Stephen Gildea.
11523 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11524 If prototypes are supported, use them to check this at compile-time,
11525 instead of trying to check it at run-time. If we must do a run-time
11526 check, assume that setvbuf is standard when cross-compiling, as
11527 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11528 Bug reported by Paul D. Smith.
11530 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11531 argument specifying location of getloadavg.c. This removes a
11532 FIXME. This idea was taken from Jim Meyering's implementation in
11533 textutils.
11534 * doc/autoconf.texi (Particular Functions): Document this.
11535 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11536 that's what the code does; this fixes a bug reported by
11537 Paul D. Smith.
11539 2002-05-03 Akim Demaille <akim@epita.fr>
11541 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11542 autopoint instead of gettextize.
11543 ($uses_alocal): Rename as...
11544 ($uses_aclocal): this.
11545 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11546 Suggested by Bruno Haible.
11548 2002-05-03 Akim Demaille <akim@epita.fr>
11550 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11552 2002-04-29 Paul Eggert <eggert@twinsun.com>
11554 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11555 files to be 1 second older; just set them to be the same time.
11556 Also, sleep 1 second after the first aclocal, to work around
11557 problems with sub-second time stamps on the input files.
11559 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11561 * doc/autoconf.texi: Mention "set -e -x" lossage
11562 under node "Limitations of Builtins".
11564 2002-04-29 Akim Demaille <akim@epita.fr>
11566 * doc/install.texi: Better wording for setting variables when
11567 running configure.
11568 From Christian Cornelssen.
11570 2002-04-29 Akim Demaille <akim@epita.fr>
11572 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11573 of lack of $LINENO support, then the test will compare the $LINENO
11574 in testsuite vs. the lineno in the test file. This is wrong, of
11575 course.
11576 Be sure to protect it.
11577 Reported by Patrick Welche.
11579 2002-04-25 Akim Demaille <akim@epita.fr>
11581 * doc/autoconf.texi (Obsolete Macros): Typo.
11582 Reported by Vladimir Volovich.
11584 2002-04-25 Akim Demaille <akim@epita.fr>
11586 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11587 than some of the input files, hence, on the second run of aclocal,
11588 if some of its input are younger, make them older.
11589 Suggested by Paul Eggert.
11591 2002-04-25 Akim Demaille <akim@epita.fr>
11593 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
11594 Thanks to Paul Eggert.
11596 2002-04-25 Akim Demaille <akim@epita.fr>
11598 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
11599 and ac_subst_vars be sh variables containing the list of
11600 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11601 DEFAULT diversion.
11602 (_AC_INIT_PREPARE): Use them to log them.
11603 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11604 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11605 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11606 _AC_SUBST_FILES and _AC_SUBST_VARS.
11607 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11609 2002-04-24 Akim Demaille <akim@epita.fr>
11611 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11612 autoheader, so that automake does not complain about a missing
11613 config.h.in that was to be created.
11615 2002-04-23 Akim Demaille <akim@epita.fr>
11617 * bin/autoheader.in (parse_args): --warning takes an argument.
11618 Fixes PR/220.
11620 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
11622 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
11623 and bb.out when cleaning up.
11625 2002-04-22 Akim Demaille <akim@epita.fr>
11627 Version 2.53a.
11629 2002-04-22 Akim Demaille <akim@epita.fr>
11631 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
11633 2002-04-22 Akim Demaille <akim@epita.fr>
11635 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
11636 comma.
11637 Reported by Gregory Giannoni.
11639 2002-04-22 Akim Demaille <akim@epita.fr>
11641 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
11642 Fixes false failures on Darwin.
11644 2002-04-21 Paul Eggert <eggert@twinsun.com>
11646 * TODO, bin/autoupdate.in, doc/autoconf.texi,

11648 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
11649 tests/tools.at: Minor spelling and grammar fixes.
11651 2002-04-20 Paul Eggert <eggert@twinsun.com>
11653 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
11654 ZSH_VERSION fixes. Bug reported by Raja R Harinath.

11666 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
11667 Minor spelling and grammar fixes.
11669 * doc/autoconf.texi: Follow the outline suggested in the GNU
11670 Sample Texts sections of the Texinfo 4.2 manual. Most
11671 importantly, this makes sure that the copyright notices appear in
11672 all output formats. You probably need Texinfo 4.2 to generate
11673 the manual now.
11675 Fix some bugs when using "$@" when there might be zero positional
11676 arguments in cases where this matters.
11678 * bin/autoconf.as: Rewrite so that the problem does not come up.

11693 Use Zsh alias to work around problem.
11694 * tests/atgeneral.m4 (AT_INIT): Likewise.
11696 * tests/c.at: We can't have zero arguments, so remove workaround
11697 that is not portable to Zsh.
11699 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
11701 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
11702 from aclocal.m4 too.
11704 2002-04-12 Akim Demaille <akim@epita.fr>

11708 2002-04-10 Akim Demaille <akim@epita.fr>
11710 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
11711 workaround for ${1+"$@"}.
11712 * doc/autoconf.texi (Shell Substitutions): Explain it.
11713 From Oliver Kiddle and Peter Stephenson.
11715 Have M4sh perform minimal shell sanitizing.
11717 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
11718 part into...
11719 (_AS_PREPARE): this new macro.
11720 (AS_PREPARE): New.
11721 (AS_INIT): Invoke AS_SHELL_SANITIZE.
11722 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
11724 Adjust Autoconf and Autotest.
11726 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11727 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11728 * lib/autotest/general.m4 (AT_INIT): Likewise.
11729 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11730 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
11731 AS_SHELL_SANITIZE.
11733 Use this M4sh to generate Autoconf's shell scripts.
11735 * tests/wrapsh.as: New, precursor of wrapsh.in.
11736 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
11737 on Autotest and M4sh.
11738 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
11739 (wrapsh.in): New target.
11740 * bin/autoconf.as: New, precursor of autoconf.in.
11741 (autoconf.in): New target.
11743 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
11745 * doc/autoconf.texi (Limitations of Make): Mention the issue
11746 with indented comments in rules.
11748 2002-04-09 Andreas Schwab <schwab@suse.de>
11750 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
11751 ac_top_builddir when setting ac_abs_top_builddir.
11753 2002-04-06 Kevin Ryde <user42@zip.com.au>
11755 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
11756 (Portable Shell): Cross reference to Systemology.
11758 2002-04-05 Akim Demaille <akim@epita.fr>
11760 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
11761 directories when descending in a SUBDIRS.
11762 Reported by Ezra Peisach.
11764 2002-04-04 Andreas Schwab <schwab@suse.de>
11766 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
11767 contains no literal separators.
11769 2002-04-03 Akim Demaille <akim@epita.fr>
11771 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
11772 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
11773 Use dnl, not the KILL diversion.
11774 Extracted from...
11775 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
11776 (AC_CONFIG_LINKS): here.
11777 Adjust.
11778 Don't use the KILL diversion, as it kills spurious output, which
11779 results in failures being hidden.
11780 Use m4_defn where appropriate.
11781 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11782 after the second argument.
11783 Use m4_defn.
11784 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
11785 syntax, as it is provided by M4sugar.
11786 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
11788 2002-04-03 Andreas Schwab <schwab@suse.de>
11790 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
11791 expanded if $# <= 2.
11793 * bin/autoreconf.in (autoreconf): Run automake after rerunning
11794 aclocal.
11796 2002-04-03 Akim Demaille <akim@epita.fr>

11800 Also recognize *.bb and *.bbg as compilation byproducts.
11801 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
11802 (_AC_COMPILER_OBJEXT): Use them.
11803 Fixes Debian #138666.
11805 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11807 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11809 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11810 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11811 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11812 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11813 (AC_C_CONST): Same.
11814 (AC_C_INLINE): Same.
11815 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
11816 * doc/autoconf.texi, NEWS: Document.
11817 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
11818 AC_C_CROSS.
11820 2002-04-02 Akim Demaille <akim@epita.fr>

11823 _AS_MKDIR_P_PREPARE.
11825 2002-03-28 Kevin Ryde <user42@zip.com.au>
11827 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11828 to avoid versions of HP C which don't allow that.
11830 2002-03-27 Paul Eggert <eggert@twinsun.com>
11832 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11833 (AS_SHELL_SANITIZE): Invoke it.
11834 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
11836 2002-03-26 Akim Demaille <akim@epita.fr>
11838 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
11840 2002-03-26 Akim Demaille <akim@epita.fr>
11842 * doc/autoconf.texi (Introduction): The GNATS base moved.
11844 2002-03-25 Paul Eggert <eggert@twinsun.com>
11846 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11847 as POSIX requires, as it doesn't work with Zsh.
11848 * doc/autoconf.texi (Assignments): Document the problem.
11850 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11852 * doc/autoconf.texi (Limitations of Make): Mention more issue
11853 about VPATH, overriding of macros in sub-makes, and handling of
11854 SHELL.
11856 2002-03-21 Paul Eggert <eggert@twinsun.com>
11858 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11859 problem with here-document buffer boundaries.
11861 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11862 when reinvoking the shell, to work around problems with installers
11863 who put strange things like "cd" commands in their environments.
11865 2002-03-19 Akim Demaille <akim@epita.fr>
11867 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
11868 From Aaron Ucko.
11870 2002-03-19 Akim Demaille <akim@epita.fr>
11872 * bin/autoscan.in (scan_file): Specify the location in `&used'
11873 invocations.
11874 From Nicolas Joly.
11876 2002-03-19 Akim Demaille <akim@epita.fr>
11878 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
11879 From Nishio Futoshi.
11881 2002-03-19 Akim Demaille <akim@epita.fr>
11883 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11885 2002-03-18 Paul Eggert <eggert@twinsun.com>
11887 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11888 (Limitations of Usual Tools): Add mkdir section.
11890 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11891 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11892 back on AS_DIRNAME to compute prefixes otherwise; this is
11893 roughly what mkinstalldirs does. That way, we need not have
11894 our own filename disassembler. The old disassembler did not
11895 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11897 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11898 Create at_test_all by a series of assignments,
11899 not by a single assignment of a long string. The latter causes ksh
11900 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11901 presumably because of a buffer overrun.
11903 2002-03-14 Paul Eggert <eggert@twinsun.com>
11905 * lib/autotest/general.m4 (at_times_skip):
11906 Renamed from at_times. Now a boolean.
11907 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11908 says 'times: not found'.
11910 2002-03-14 Akim Demaille <akim@epita.fr>
11912 * bin/autoreconf.in (&study_gettextize): New.
11913 (&autoreconf): Handle newest gettextize.
11914 Rerun aclocal if needed.
11915 Suggested by Andreas Schwab.
11917 2002-03-13 Akim Demaille <akim@epita.fr>
11919 * doc/autoconf.texi (Special Shell Variables): More about IFS.
11921 2002-03-13 Akim Demaille <akim@epita.fr>
11923 * doc/autoconf.texi (Header Portability): New.
11924 Add information about stdint.h and inttypes.h from Paul Eggert.
11926 2002-03-13 Akim Demaille <akim@epita.fr>
11928 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11929 -p'.
11930 From Bob Proulx.
11932 2002-03-12 Akim Demaille <akim@epita.fr>
11934 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11935 m4_require.
11937 2002-03-11 Andreas Schwab <schwab@suse.de>
11939 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11940 does not do it if --with-lispdir is given.
11942 2002-03-08 Akim Demaille <akim@epita.fr>
11944 Version 2.53.
11946 2002-03-08 Akim Demaille <akim@epita.fr>
11948 * doc/autoconf.texi (Subdirectories): Clarify that the
11949 subdirectory should exist.
11951 2002-03-08 Akim Demaille <akim@epita.fr>
11953 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11955 2002-03-08 Akim Demaille <akim@epita.fr>
11957 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11958 aliases the actual variables, and modifications of the former
11959 affect the latter.
11961 2002-03-08 Akim Demaille <akim@epita.fr>
11963 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11964 because of C-c: have m4 output in tmp files, then mv them.
11966 2002-03-08 Akim Demaille <akim@epita.fr>
11968 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

11976 2002-03-05 Akim Demaille <akim@epita.fr>
11978 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11979 Kevin Ryde.
11981 2002-03-05 Akim Demaille <akim@epita.fr>
11983 Version 2.52i.
11985 2002-03-04 Akim Demaille <akim@epita.fr>
11987 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11988 * lib/autoconf/general.m4 (AC_INIT): More informative error
11989 message for LIBOBJ.
11991 2002-03-04 Akim Demaille <akim@epita.fr>
11993 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11994 parallel builds.
11996 2002-03-04 Akim Demaille <akim@epita.fr>
11998 * doc/autoconf.texi (Transforming Names): Equality between target
11999 and host is irrelevant.
12000 (Specifying Names, Canonicalizing): Remove all references to the
12001 backward compatibility hooks. Rather, collect them all into...
12002 (Hosts and Cross-Compilation): this new section.
12003 * doc/install.texi (System Type): Ditto.
12004 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12005 that `--host' implies cross-compilation.
12007 2002-03-04 Akim Demaille <akim@epita.fr>
12009 * doc/autoconf.texi (Evaluation Macros): New.
12010 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12011 useless.
12012 (_m4_foreach): Define the variant with immediate evaluation so
12013 that it contains exactly the items, not an expression which
12014 evaluation is the current item.
12015 (m4_re_string, m4_re_word): Don't over quote them.
12017 2002-03-04 Akim Demaille <akim@epita.fr>
12019 Instead of having stacking `shift's evaluated at the end, let
12020 `foreach' loops immediately evaluate them.
12022 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12023 $*. This is the n-th time I change my mind, but hopefully this is
12024 the last...
12025 (m4_lquote): New.
12026 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12027 efficient.
12028 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12029 it was only a hack for m4_text_wrap.
12030 (m4_car2): Remove, replaced by...
12031 (m4_cdr): New.
12032 (_m4_foreach): Adjust.
12033 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12034 m4_bpatsubst for clarification.
12036 2002-03-04 Akim Demaille <akim@epita.fr>

12042 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
12043 on old systems like SunOS.

12065 From Akinori Musha.
12067 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
12069 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
12070 translate \r\n to \n.
12072 2002-02-07 Akim Demaille <akim@epita.fr>
12074 Version 2.52h.
12076 2002-02-07 Akim Demaille <akim@epita.fr>
12078 Fix Autoconf PR/209.
12079 Also reported by Frank Denis.

12083 2002-02-07 Akim Demaille <akim@epita.fr>
12085 Fix Autoconf PR/207:
12086 AC_PREFIX_PROGRAM fails with dashed program names
12088 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12089 variable when looking for the prefix program.
12090 Now it also works for shell variables.
12092 2002-02-07 Akim Demaille <akim@epita.fr>
12094 * doc/autoconf.texi (Limitations of Builtins): More about
12095 case/esac.

12099 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
12100 case/esac, some shells don't support it.
12101 Reported by Zack Weinberg.
12102 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12104 2002-02-06 Akim Demaille <akim@epita.fr>
12106 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12107 sure not to introduce newlines in at_groups.
12108 * lib/autotest/Makefile.am (autotest.m4f): Typo.
12110 2002-02-06 Akim Demaille <akim@epita.fr>
12112 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12113 is not available.
12115 2002-02-05 Paul Eggert <eggert@twinsun.com>
12117 * doc/autoconf.texi (Specific Compiler Characteristics):
12118 Describe HP-UX cc bug workaround more accurately.
12119 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12120 not unsigned long.
12121 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12122 cross-compilers, too. This undoes some of the most recent change
12123 to this file.
12125 2002-02-05 Akim Demaille <akim@epita.fr>
12127 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12128 to make sure they are up to date when `check' is run.
12130 2002-02-05 Akim Demaille <akim@epita.fr>
12132 * doc/autoconf.texi (Making testsuite Scripts): Document
12133 package.m4.

12137 * lib/freeze.mk: New.
12139 2002-02-05 Akim Demaille <akim@epita.fr>
12141 Implement `autom4te --freeze'.
12143 * bin/autom4te.in (&freeze): New.
12144 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12145 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12147 2002-02-05 Akim Demaille <akim@epita.fr>
12149 * bin/autom4te.in (&parse_args): Implement `frozen files are
12150 optional are the sum of the previous files on the command line'.
12151 Also, pass `--reload-state=' on them, so...
12152 (handle_m4): don't.
12153 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12154 (M4sh): Rely on M4sugar.
12155 (Autotest, M4sh, M4sugar): Use frozen files.
12157 2002-01-31 Akim Demaille <akim@epita.fr>
12159 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12160 * doc/autoconf.texi (Initializing configure): Adjust.
12162 2002-01-30 Akim Demaille <akim@epita.fr>
12164 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12165 alphanumeric to `-' instead of `_'.
12167 2002-01-30 Akim Demaille <akim@epita.fr>
12169 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12170 for plain code, the other for cross-compilation code. The latter
12171 is now run with GCC only.

12177 values.

12185 Reported by Alexandre Duret-Lutz and Larry Schmitt.

12189 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12190 needs an argument.
12192 2002-01-28 Akim Demaille <akim@epita.fr>
12194 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12195 AUTOTEST_PATH *after* it was set.
12196 Don't put `.' in the PATH: the user should be precise and `./' if
12197 needed. In addition, given that the test suite does some `cd', if
12198 `.' is in the path, the `tested programs' sections will report
12199 programs found in the test suite's directory, while during the
12200 tests (performed in their own directory), these programs are no
12201 longer visible. In other words, the results is confusing and
12202 useless.
12203 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
12205 2002-01-24 Akim Demaille <akim@epita.fr>

12216 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12217 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12218 Bourne. Use /bin/sh.

12233 Automake.
12235 2002-01-24 Akim Demaille <akim@epita.fr>
12237 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
12238 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
12239 Reported by Geir Ove Myhr.
12241 2002-01-21 Akim Demaille <akim@epita.fr>
12243 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
12245 2002-01-21 Akim Demaille <akim@epita.fr>
12247 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12248 message on invalid options.
12249 * bin/autom4te.in (parse_args): Don't use
12250 Autoconf::General::getopt with non valid options.
12252 2002-01-17 Jim Meyering <meyering@lucent.com>
12254 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12255 $ac_cv_exeext so we don't use an old, invalid, cached value.
12257 2002-01-11 Akim Demaille <akim@epita.fr>
12259 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
12260 Meyering.

12262 limitation.

12266 2002-01-06 Akim Demaille <akim@epita.fr>
12268 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
12269 package.m4, since is really depends upon configure.ac, not
12270 configure.
12271 * doc/autoconf.texi (testsuite Scripts): Adjust.
12272 * tests/Makefile.am (package.m4): New.
12273 EXTRA_DIST it since its a source.
12275 2002-01-06 Akim Demaille <akim@epita.fr>
12277 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12278 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12279 and PACKAGE_BUGREPORT from here...
12280 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12281 arguments.
12282 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12283 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12284 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12285 * tests/tools.at (autoheader): Adjust.
12286 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
12288 2002-01-06 Akim Demaille <akim@epita.fr>

12294 * doc/autoconf.texi (Output): Improved wording regarding use of
12295 AC_OUTPUT.
12296 From Olly Betts.
12298 2001-12-18 Kevin Ryde <user42@zip.com.au>
12300 * doc/autoconf.texi (Function Portability): Add notes on sscanf
12301 sometimes needing writable input.
12303 2001-12-17 Jim Meyering <meyering@lucent.com>
12305 * doc/autoconf.texi (New Macros): Tweak wording.
12307 2001-12-14 Akim Demaille <akim@epita.fr>
12309 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12310 trailing files, don't apply `-rf' to files which might not be
12311 created by configure (core, core.*, and *.core), but just `rm -f'.
12312 Suggested by Jonathan Kamens.
12314 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12316 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12318 2001-12-14 Akim Demaille <akim@epita.fr>
12320 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12322 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

12325 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12326 abs_srcdir, top_srcpath to abs_top_srcdir.
12327 (_AC_OUTPUT_FILES): Adjust.

12329 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12330 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12332 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
12334 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
12335 C/Fortran linking on HP/UX, by extracting the Fortran library
12336 search path from the LPATH line in the $F77 -v output.
12338 2001-12-12 Kevin Ryde <user42@zip.com.au>
12340 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12341 forbidden file descriptors table.
12343 2001-11-26 Akim Demaille <akim@epita.fr>
12345 * bin/autoscan.in (%c_keywords): Build it at top level.
12346 Map to 1 in order to simplify its uses.
12348 2001-11-26 Akim Demaille <akim@epita.fr>
12350 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12351 Remove $filepath, useless.
12352 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12353 variables, they are really part of the tokens.
12354 Split the input line on spaces and then look for tokens.
12355 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12356 because of `lex$U.$(OBJEXT)'.
12357 (&scan_files): Use "@list" instead of join.
12358 * doc/Makefile.am (CLEANFILES): Add *.fns.
12360 2001-11-26 Akim Demaille <akim@epita.fr>
12362 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
12363 Remove, replaced by...
12364 * tests/wrappl.in: Be common for all the Perl executables.
12365 In particular autoscan and autoheader want -I.
12366 * configure.ac: Adjust.
12367 * lib/autoscan/headers: errno.h is portable.
12369 2001-11-26 Akim Demaille <akim@epita.fr>
12371 * bin/autoscan.in (used): New.
12372 Use it.
12374 2001-11-26 Akim Demaille <akim@epita.fr>
12376 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12377 directives.
12378 (&scan_sh_file): Remove a duplicate pattern.
12379 (&check_configure_ac): Use long options.
12380 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
12382 2001-11-26 Akim Demaille <akim@epita.fr>
12384 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
12385 Before, having a line containing the opening of a multi line
12386 comment made the whole line be ignored.
12388 2001-11-26 Akim Demaille <akim@epita.fr>
12390 * doc/autoconf.texi (Using an Autotest Test Suite): New.
12391 (testsuite Scripts): Be one of its subsection.
12392 (Autotest Logs): New.
12394 2001-11-26 Akim Demaille <akim@epita.fr>
12396 Test groups are now run two directories deeper.
12398 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12399 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12400 at_top_builddir.
12401 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12402 top_srcdir, builddir and top_builddir.
12403 Use `at_*dir' relatively to the directory containing the
12404 suite, use `*dir' when relatively to the current group dir.
12406 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12408 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12409 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12410 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12411 spelling errors.
12413 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12415 * doc/autoconf.texi (Using System Type): Add an example of `case
12416 $host' usage so people quit using `case $target' everywhere.
12418 2001-11-22 Akim Demaille <akim@epita.fr>
12420 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12421 spotted by Jim Meyering.
12423 2001-11-16 Paul Eggert <eggert@twinsun.com>
12425 This patch implements a `long double' suggestion by Oliver Kiddle.
12427 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12428 static, to catch errors if the value isn't known at compile-time
12429 and the compiler supports dynamic arrays. Change its name from
12430 `_array_' to `test_array' to avoid potential name clashes.
12431 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12432 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12433 better than double. Catch a bug in GCC 2.95.2 x86.
12434 * doc/autoconf.texi (C Compiler): Document the above.
12435 * NEWS: Likewise.
12437 2001-11-13 Akim Demaille <akim@epita.fr>
12439 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12440 hand.
12441 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12443 2001-11-13 Akim Demaille <akim@epita.fr>
12445 * lib/autotest/general.m4 (AT_INIT): After having run the test
12446 group, go back to the initial directory, not to at_suite_dir.
12448 2001-11-13 Akim Demaille <akim@epita.fr>
12450 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12451 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12452 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12453 option.
12454 (AT_CHECK_CONFIGURE): Use absolute paths.
12455 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12456 The problem is still the old one: there is no means in M4 (that I
12457 know about) to create a defining macro, because there is no means
12458 to create `$1' etc., therefore, the defining macro ``swallows''
12459 all the arguments meant to the defined macro.
12461 2001-11-13 Akim Demaille <akim@epita.fr>
12463 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12464 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12465 configure.ac.
12466 * tests/aclocal.m4: Remove, as it is no longer used.
12468 2001-11-13 Akim Demaille <akim@epita.fr>
12470 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12471 variable names when referring to a single test group, or to
12472 `suite' when referring to the whole test suite.
12473 `at_last_test' is removed: m4 compute at_format itself.
12474 (at_stdout, at_stder1, at_stderr): New variables.
12475 (AT_CHECK): Use them.
12477 2001-11-13 Akim Demaille <akim@epita.fr>
12479 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12480 in PATH.
12481 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12482 Do it as soon as a test fails, don't wait till the end of the test
12483 suite.
12484 Don't remove $as_me.[0-9]*, since these files no longer exist.
12486 2001-11-13 Akim Demaille <akim@epita.fr>
12488 * tests/tools.at: Use absolute paths, since we are no longer run
12489 in place.
12491 2001-11-13 Akim Demaille <akim@epita.fr>
12493 Now that tests are running in their own private dir, there is no
12494 need to list the files to remove at the end of tests groups.
12496 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12497 (AT_data_files, at_data_files): Remove.

12499 (AT_INIT): Adjust.
12500 Remove the group dir if !debug && !failed.
12501 * tests/atspecific.m4: Adjust.
12503 2001-11-13 Akim Demaille <akim@epita.fr>
12505 Start a new layout for Autotest: `testsuite' creates
12506 `testsuite.dir' in which the at-check-line etc. files are to be
12507 found, and `testsuite.dir/003' where the test group 3 is run.
12509 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12510 at_check_line_file, at_format, at_test_normalized, at_group_dir
12511 are new variables.
12512 Create the directories.
12513 Use absolute paths for at- files.
12514 (AT_CHECK): Adjust.
12516 2001-11-11 Michael Matz <matz@kde.org>
12518 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12519 (m4_car2): New.
12520 (m4_car): Properly quote arguments.
12522 2001-11-13 Akim Demaille <akim@epita.fr>
12524 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12525 with stricter rules on LIBOBJS.
12527 2001-11-12 Paul Eggert <eggert@twinsun.com>
12529 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12530 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12531 __PROTOTYPES too.
12533 2001-11-12 Akim Demaille <akim@epita.fr>
12535 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12537 2001-11-12 Akim Demaille <akim@epita.fr>

12542 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12543 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12544 specify to what the macro should be defined (typically to 1).
12546 2001-11-12 Akim Demaille <akim@epita.fr>
12548 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12549 From Jim Meyering.
12551 2001-11-12 Akim Demaille <akim@epita.fr>
12553 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12554 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12555 definition used by Automake where LEX is +/- "${missing} lex" and
12556 `missing' itself contains variables.
12558 2001-11-12 Akim Demaille <akim@epita.fr>
12560 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12561 Now that M4sh pushes BODY, the comments were output at the end of
12562 the test suites.
12564 2001-11-08 Akim Demaille <akim@epita.fr>
12566 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12567 that we can trace macros from aclocal.m4.
12568 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12569 obsoleted, and redirect to the former anyway.
12570 Reported by Ralf Corsepius.
12572 2001-11-08 Akim Demaille <akim@epita.fr>
12574 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12575 processed only if present.
12576 * tests/torture.at (Configuring subdirectories): Use autoreconf
12577 instead of successive calls to autoconf.
12578 Add a nonexistent subdirectory to exercise the patch above.
12579 Reported by Ralf Corsepius.
12581 2001-11-08 Kevin Ryde <user42@zip.com.au>
12583 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12584 doesn't accept .S files.

12591 * bin/autom4te.in (warn_forbidden): New.
12592 (handle_output): Use it.
12593 Read m4_pattern_forbid with messages.
12595 2001-11-05 Akim Demaille <akim@epita.fr>
12597 * bin/autom4te.in (--normalize): Remove.
12598 * lib/autom4te.in: Adjust.
12600 2001-11-05 Akim Demaille <akim@epita.fr>
12602 * tests/Makefile.am (testsuite): Rename this target as...
12603 ($(TESTSUITE)): this.
12604 From Nicolas Joly.
12606 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12608 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12609 the --prefix option, also remove it's argument.
12611 2001-11-05 Akim Demaille <akim@epita.fr>
12613 * doc/autoconf.texi (testsuite Invocation): Update.
12614 (Writing testsuite.at): Update.

12622 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12623 (&file_name_is_absolute): New, wrappers around routines from
12624 File::Spec.
12625 Use and export them.
12626 (&find_configure_ac): Optionally take a directory where to look at.
12627 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12628 the arguments.
12629 Default @ARGV to `.', not find_configure_ac.
12630 (&autoreconf): Argument is a directory.
12631 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12632 * doc/autoconf.texi (autoreconf Invocation): Update.
12634 2001-11-03 Akim Demaille <akim@epita.fr>
12636 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12637 (@export_forward_subs): New.
12638 Add basename, dirname, and fileparse.
12639 (@EXPORT): Adjust.
12640 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12641 Don't look for aclocal flags if we already know aclocal is not
12642 used.
12643 Move aclocal.m4t only if it exists.
12644 Reported by Ezra Peisach.
12646 2001-11-03 Akim Demaille <akim@epita.fr>
12648 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12649 passed on command line, defaulting to ./configure.ac if present.
12650 (&maybe_autoreconf, File::Find): Remove, unused.
12651 (&autoreconf): If autoconf is not used, don't try to trace.
12653 2001-11-02 Akim Demaille <akim@epita.fr>
12655 * configure.ac: Bump to 2.52g.
12657 2001-11-02 Akim Demaille <akim@epita.fr>
12659 Version 2.52f.
12661 2001-11-02 Akim Demaille <akim@epita.fr>
12663 * config/config.guess, config/config.sub, doc/standards.texi:
12664 * config/lispdir.m4: Update from masters.
12665 * configure.ac: Bump to 2.52f.
12667 2001-11-02 Akim Demaille <akim@epita.fr>
12669 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12670 Don't run aclocal when aclocal.m4 is not from aclocal.
12671 From Ezra Peisach.
12672 Don't run libtoolize and gettextize if --install is not given.
12674 2001-11-01 Paul Eggert <eggert@twinsun.com>
12676 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12677 be invoked before _AS_LINENO_PREPARE.
12678 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12679 than character ranges.
12681 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12682 invoking AS_BASENAME. Set the locale variables to 'C' if
12683 possible, as POSIX requires this to get the traditional
12684 behavior.
12685 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12687 2001-10-31 Paul Eggert <eggert@twinsun.com>
12689 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12690 with {}, as that triggers a bug in Bash 2.05.
12692 (_AS_LINENO_PREPARE): Use Sed rather than
12693 Awk. Fix the sed prepass to work even if there are multiple
12694 instances of $LINENO on the same line. Do not substitute for
12695 other variables like $LINENOT. Do not check file dates; such a
12696 check is unreliable on sufficiently fast machines, and removing
12697 the check makes the code simpler and more reliable. Check for
12698 output and chmod failures.
12700 * doc/autoconf.texi (Special Shell Variables): Document
12701 the above.
12703 2001-10-31 Akim Demaille <akim@epita.fr>
12705 * tests/Makefile.am (atconfig): Remove this target, Automake
12706 handles it now.
12708 2001-10-31 Akim Demaille <akim@epita.fr>
12710 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12711 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12712 provided, while it is optional.
12713 * configure.ac: Adjust.
12715 2001-10-26 Paul Eggert <eggert@twinsun.com>
12717 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12718 lib/Autom4te/Struct.pm:
12719 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12720 with 5.005_02.
12722 * doc/autoconf.texi (Special Shell Variables): Document some
12723 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12725 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12726 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12727 eval $LINENO is not portable in practice.
12729 2001-10-24 Akim Demaille <akim@epita.fr>
12731 * lib/Autom4te/General.pm (backname): New.
12733 2001-10-24 Akim Demaille <akim@epita.fr>
12735 * m4/: Remove, merged into...
12736 * config/: here.
12738 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
12740 * doc/autoconf.texi (Shellology): Mention the problems with bash
12741 2.05's use of ANSI quoting in its `set' builtin.
12743 2001-10-22 Paul Eggert <eggert@twinsun.com>
12745 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12746 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12747 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12748 POSIX decided to standardize on the int flavor of strerror_r.
12749 Always do char* test, as there's no reason not to.
12750 Assign to a char* var, to catch strerror_r that returns int*.
12752 * doc/autoconf.texi (Particular Functions):
12753 Document the above changes. Also, document the fact that
12754 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12756 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12758 2001-10-20 Akim Demaille <akim@epita.fr>
12760 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
12761 the executable was missing from the log.

12765 * lib/Autom4te/General.pm (&update_file): If destination is
12766 unchanged, remove the source.
12767 (&up_to_date_p): Don't be verbose, be debug.
12768 * bin/autoreconf.in: No longer support --m4dir.
12769 (&autoreconf): Display the full path of the configure.ac we are
12770 studying.
12771 Trace it only once.
12772 Be sure to honor --force with gettextize.
12773 Always run aclocal.
12774 * doc/autoconf.texi: Adjust.
12776 2001-10-20 Akim Demaille <akim@epita.fr>
12778 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12779 Remove, dead.
12780 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12781 `intl' is already present, as it refuses unless --force.
12782 (&parse_args): Use -I, --include instead of the old Autoconf
12783 options.
12784 ($localdir, $autoconf_dir): Remove.
12785 (@include): New.
12786 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12788 2001-10-19 Jens Petersen <petersen@redhat.com>

12797 Don't mention `automatically' in addition to `generated'.
12798 * tests/torture.at (#define header templates): Adjust.
12800 2001-10-19 Akim Demaille <akim@epita.fr>
12802 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
12803 comment, explain how to install automatic mode selection.
12804 From Russ Allbery.
12806 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
12808 * bin/autoreconf.in (autoreconf): Display the path to the
12809 configure.ac being studied.
12811 2001-10-18 Paul Eggert <eggert@twinsun.com>
12813 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
12814 long, to work around a bug in the HP C compiler version HP92453-01
12815 B.11.11.23709.GP.
12817 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
12818 (AS_BASENAME_EXPR): New macro.
12819 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12820 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
12821 and fall back on 'sed' only if the other two fail. This makes
12822 AS_BASENAME act more like AS_DIRNAME.
12823 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
12824 contains white space.
12825 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
12826 Use AS_DIRNAME, since I think it's now DOS-friendly.
12827 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
12828 Allow "dirname //FOO" to return either / or //, as POSIX allows
12829 either behavior.
12831 2001-10-10 Akim Demaille <akim@epita.fr>
12833 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

12835 From Eric Sharkey.

12839 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

12934 2001-10-08 Akim Demaille <akim@epita.fr>
12936 Use `add-log-current-defun-function' for ChangeLog creation.
12937 Suggested by Tom Tromey.

12954 include handle the m4_pattern_*, no longer push the
12955 BODY diversion nor set the /bin/sh line, AS_INIT does it.
12956 * lib/autotest/general.m4 (AT_INIT): Likewise.
12957 * tests/base.at: Adjust the tests to use AS_INIT.
12958 * tests/tools.at (AT_DATA_FORBIDDEN): New.

12964 * doc/autoconf.texi (config.status Invocation):
12965 CONFIG_SHELL defaults to a shell that supports LINENO if available.

12968 shell does not support LINENO, and if CONFIG_SHELL is unset or
12969 empty, and if we can find a shell that does support LINENO,
12970 then set CONFIG_SHELL to that shell and then re-execute
12971 ourselves with CONFIG_SHELL.
12973 2001-10-05 Paul Eggert <eggert@twinsun.com>
12975 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
12976 doesn't exist. Remove *.tmp, as a .tmp file is created during the
12977 build of $(TESTSUITE).
12979 2001-10-05 Akim Demaille <akim@epita.fr>
12981 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

13002 (AS_SHELL_SANITIZE): here. Use it.
13003 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
13004 From Paul Eggert.
13006 2001-10-04 Akim Demaille <akim@epita.fr>
13008 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
13009 combination of Awk and sed to replace $LINENO.
13011 2001-10-02 Paul Eggert <eggert@twinsun.com>
13013 * doc/autoconf.texi (Limitations of Builtins): You can't use
13014 "source"; it's not portable. Remove confusing and
13015 somewhat-incorrect example involving "." and "/".
13017 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13018 compatibility with POSIX shells.
13020 2001-10-02 Akim Demaille <akim@epita.fr>

13023 instead of exec'ing to preserve $0 and $@.
13025 2001-10-01 Akim Demaille <akim@epita.fr>
13027 * tests/testsuite (AT_INIT) <at_pass_list>: New.
13028 Don't run twice the same test.

13046 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13047 Don't use nested parenthesization. This patch was originally
13048 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13049 but somehow it didn't get incorporated then.
13050 * doc/autoconf.texi (Limitations of Usual Tools):
13051 Clarify remark about sed and nested parenthesization.
13053 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13054 Report an error if the size cannot be determined even though
13055 the type exists.
13056 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13057 Check for `expr' arithmetic overflow, and for compilation failure,
13058 and invoke a new argument $4 if either is discovered.
13059 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13060 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13062 2001-09-28 Akim Demaille <akim@epita.fr>

13070 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
13071 (AT_TESTED): this.

13073 Output `AT_tested' only when existing.
13074 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
13076 2001-09-27 Akim Demaille <akim@epita.fr>
13078 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
13079 generates too many bug reports.
13081 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
13082 status when executing the ACTION-IF-FALSE.
13083 * tests/base.at (AC_TRY_*): Rename as...

13090 * tests/c.at (Extensions, C keywords)
13091 (Broken/missing compilers, AC_PROG_CPP with warnings)
13092 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
13093 (AC_PROG_CPP requires AC_PROG_CC): here and...
13094 * tests/fortran.at (GNU Fortran 77): there.
13095 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13096 AC_TRY_RUN is about compilation, not shell commands.
13097 (Test Programs): AC_TRY_RUN works as used to be advertised.
13099 2001-09-27 Akim Demaille <akim@epita.fr>
13101 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13102 Raja R Harinath:
13103 Be sure to detect when $LINENO always returns the same value.
13104 Look for the original script, basename($0) is certainly not
13105 enough.
13106 Pass the CLI arguments to `$as_me.lineno'.
13108 2001-09-25 Akim Demaille <akim@epita.fr>
13110 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

13118 of --language now.
13120 2001-09-23 Akim Demaille <akim@epita.fr>
13122 * doc/autoconf.texi (Top): Wrap in @ifnottex.
13124 2001-09-23 Akim Demaille <akim@epita.fr>
13126 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
13127 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
13128 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
13129 builddir, buildpath, top_builddir, and top_buildpath.
13130 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
13131 the current directory.
13132 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
13133 variables *before* changing the current directory.

13136 variables.
13138 * lib/autotest/general.m4: Do not reset AT_victims.
13139 Don't compute at_srcdir nor at_top_srcdir.
13141 * tests/tools.at: Hence use top_srcdir.
13143 * tests/Makefile.am, tests/autoconf, tests/autoheader,
13144 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
13145 Remove.
13146 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
13147 * tests/wrapsh.in, tests/autoupdate.in: New.
13148 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
13149 * configure.ac: Build the position independent wrappers.
13151 * man/Makefile.am: Now that test wrappers are position
13152 independent, use them and drop dark envvar magic.
13154 2001-09-23 Akim Demaille <akim@epita.fr>
13156 * doc/autoconf.texi (Common Shell Constructs): Rename as...
13157 (Programming in M4sh): this.
13158 Promote to @section.

13175 over-escaping.

13185 (Autoconf): Adjust.
13187 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
13189 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

13198 2001-09-22 Akim Demaille <akim@epita.fr>
13200 * lib/autoconf/autotest.m4: Create `package.m4'.
13201 * tests/Makefile.am (package.m4): Remove.
13203 2001-09-22 Akim Demaille <akim@epita.fr>
13205 Rely on `$LINENO' when possible instead of `__oline__'.
13207 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13208 `$LINENO' support replacement when not supported.
13209 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
13210 them explicitly to be sure they are not output before this section
13211 (via m4_require). Cosmetic only.
13212 * lib/autoconf/c.m4, lib/autoconf/general.m4,
13213 * lib/autoconf/programs.m4: Replace all the occurrences of
13214 `__oline__' with `$LINENO'.
13215 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
13217 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
13219 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
13220 character (u: -> ue) in a code comment.
13221 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
13222 it works.
13224 2001-09-21 Akim Demaille <akim@epita.fr>
13226 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13227 Suggested by Jim Meyering.
13229 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13231 * lib/autoconf/programs.m4: Use extensions listed in
13232 $ac_executable_extensions when looking for programs.
13234 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13236 * lib/autoconf/general.m4: Fix a small Englisho.
13237 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
13238 setting up ac_dir_suffix and ac_top_builddir.
13239 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
13241 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13243 * doc/autoconf.texi (File System Conventions): Clarify the use of
13244 PATH_SEPARATOR.
13245 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
13246 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
13247 be used instead of ':'.
13248 * lib/autotest/general.m4: Replace occurrences of ':' in
13249 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
13251 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13253 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
13254 arguments. Fixed a typo.
13256 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13258 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13259 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13261 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13263 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
13264 * bin/autoupdate.in: Ditto.
13265 * bin/autoheader.in: Reworded a few comments.
13266 * bin/autoconf.in: Reworded help text for a few options.
13267 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
13268 * bin/autoscan.in, bin/autoupdate.in: Ditto.
13270 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13272 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13273 already have $file). Set output files to binary mode (helps avoid
13274 CR issues on DOSish systems).
13276 2001-09-19 Akim Demaille <akim@epita.fr>
13278 * lib/autotest/general.m4: Englishoes.
13279 From Tim Van Holder and Alexey Mahotkin.
13281 2001-09-18 Paul Eggert <eggert@twinsun.com>
13283 * doc/autoconf.texi (Common Shell Constructs): New node,
13284 documenting AS_DIRNAME.
13285 (Limitations of Usual Tools): Refer to it when discussing dirname.
13286 Also, update discussion of POSIX standard to reflect latest draft.
13288 * lib/autoconf/c.m4:
13289 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13291 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13292 Do not pass a first argument with leading '-'
13293 to expr, by parenthesizing initial integers that might be negative.
13295 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13296 now merely checks whether it is an error to pass an argument
13297 to getpgrp.
13299 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13300 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13301 whether it is a (compile-time) error to pass an argument to
13302 getpgrp. This simpler test supports the revised documentation,
13303 and is all that AC_FUNC_GETPGRP's users really need.
13305 2001-09-18 Akim Demaille <akim@epita.fr>
13307 * doc/autoconf.texi (Limitations of Make) <$<>: New.
13309 2001-09-18 Akim Demaille <akim@epita.fr>
13311 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
13312 `{}'.
13313 * lib/autotest/general.m4 (AT_INIT): Adjust.
13315 2001-09-18 Paul Wagland <paul@wagland.net>
13317 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13318 correctly.
13319 Add test for AS_BASENAME.
13320 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13321 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13322 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13323 * tests/base.at: Fixed the expected responses. The old ones were
13324 one line out...
13325 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13326 the documentation claims it should (and how it behaved in 2.13).
13328 2001-09-18 Akim Demaille <akim@epita.fr>
13330 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13331 the AC_CONFIG_COMMANDS invocation.
13332 This also solves the name clash problems.
13333 Don't set the package's ID.
13334 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13335 No longer to be shipped.
13336 (version.in): Remove.
13337 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13338 * lib/autoconf/status.m4: Adjust.
13339 Use `m4_PACKAGE_STRING'.
13340 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13341 the only optional argument is the name of the test suite.
13342 Expect `package.m4' to define the package signature.
13343 * lib/autom4te.in (Autotest): Add `package.m4?'.
13344 * tests/Makefile.am (package.m4): New.
13345 * tests/suite.at: ifnames is a victim.
13347 2001-09-18 Akim Demaille <akim@epita.fr>
13349 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13350 AC_LIBSOURCE, AC_CONFIG_FILES.
13351 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13352 program version string doesn't match the package's.
13353 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
13354 after `(cached)'.
13356 2001-09-17 Paul Eggert <eggert@twinsun.com>
13358 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13359 Allow expression to return any value that can fit into unsigned long
13360 (not int, as before). Check for output errors.
13362 2001-09-17 Bruno Haible <haible@ilog.fr>
13364 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13365 Always include <stdio.h> and <stdlib.h>. Evaluate
13366 the expression in an extra function before these includes. Call
13367 fprintf "%d" only after ensuring the argument is of type 'int'.
13368 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13370 2001-09-17 Paul Eggert <eggert@twinsun.com>
13372 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13373 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13374 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13375 when they don't exist.
13377 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13378 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13379 need it.
13381 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13382 version with the version used by fileutils 4.1, except use
13383 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13384 we don't need it.
13386 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13388 2001-09-13 Akim Demaille <akim@epita.fr>
13390 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
13391 _first_.
13392 Reported by Gerrit P. Haase.
13394 2001-09-13 Akim Demaille <akim@epita.fr>
13396 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
13397 m4_defn'ing is valid.
13399 2001-09-13 Akim Demaille <akim@epita.fr>
13401 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
13402 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
13403 Use it.
13405 2001-09-13 Akim Demaille <akim@epita.fr>

13428 * lib/autotest/general.m4 (AT_INIT): Create and remove
13429 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

13540 2001-09-05 Akim Demaille <akim@epita.fr>

13543 the maintainer is dumb enough to do that...
13545 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13546 excellence in M4 quotation: consider `__file__' is active.
13548 And BTW, when invoking m4, pass the --include in the right order:
13549 the wrong one.
13551 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
13552 4m.

13579 New, extracted from main.
13580 Use IO::File wherever possible.
13581 (input.m4): Be constant, use -I instead of hard coding $tmp.

13583 Don't invoke `_au_disable', since ac was not loaded, but just
13584 `unm4.m4'.
13586 2001-08-31 Akim Demaille <akim@epita.fr>
13588 Version 2.52d.

13613 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
13614 (testsuite Scripts): There is no such thing as `atconfig.in'.
13615 And actually one diagram is missing: test suite runtime.
13617 2001-08-31 Akim Demaille <akim@epita.fr>
13619 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
13620 inverse order.
13622 2001-08-31 Akim Demaille <akim@epita.fr>
13624 * bin/autoupdate.in (@include): `installcheck' revealed the path
13625 to m4sugar was lacking!
13627 2001-08-31 Akim Demaille <akim@epita.fr>
13629 * man/Makefile.am (.x.1): We really have to pass
13630 autom4te_perllibdir.
13632 2001-08-31 Akim Demaille <akim@epita.fr>
13634 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

13640 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
13641 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
13642 Use directly autom4te, not autoconf.

13667 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
13668 (autoheader): Pass --force since the test suite goes too fast for
13669 the time stamps.
13670 Adjust to the new autoheader messages.
13672 2001-08-31 Akim Demaille <akim@epita.fr>
13674 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
13675 Check the completeness of the #template.

13685 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
13686 `autoheader: `config.hin' is created'.
13687 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
13689 2001-08-31 Akim Demaille <akim@epita.fr>
13691 * bin/autoheader.in: Rewrite in Perl.

13694 2001-08-31 Akim Demaille <akim@epita.fr>

13697 Map --localdir, --autoconf-dir onto it.
13698 Forward autom4te's options instead of interpreting them.
13699 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
13700 There is no such envvar since the inception of autom4te.cfg.
13701 * bin/autom4te.in (&parse_args): Uniquify `@include'.
13702 * bin/autoupdate.in: Adjust, and perform more control.

13706 2001-08-31 Akim Demaille <akim@epita.fr>
13708 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
13709 * bin/autom4te.in (&find_file): Support `FILE?' standing for
13710 optionally `FILE'.
13711 Use -e, not -f, since /dev/null for instance is OK.
13712 (&parse_args): Adjust.
13713 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
13715 2001-08-31 Akim Demaille <akim@epita.fr>
13717 * configure.ac: Also find tested executables in bin.
13718 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
13719 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
13720 installed peer executables, only PATH is allowed to resolve it.
13721 Pass `autoconf_dir' via options, not via invisible envvars.
13722 * lib/Autom4te/General.pm (&find_peer): Remove.
13723 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
13724 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
13725 * man/Makefile.am: Let help2man rely on PATH instead of trying to
13726 find the executables for it.
13727 * tests/Makefile.am: Major cleanup. Too lazy to document...
13728 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13729 We only need PERL.
13730 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13731 indeed related to running the test suite, while passing
13732 --autoconf-dir and others is related to running non installed
13733 Autoconf executables. So don't do that, leave it to...
13734 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
13735 * tests/autoscan: New.
13736 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
13737 refer to library files: rely on --language.

13741 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

13750 2001-08-29 Akim Demaille <akim@epita.fr>
13752 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
13753 Suggested by Paul Eggert.
13755 2001-08-29 Akim Demaille <akim@epita.fr>
13757 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
13758 download in a tmp dir.
13760 2001-08-29 Akim Demaille <akim@epita.fr>
13762 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

13781 * lib/autotest/general.m4: Use
13782 foo=`(command) 2>/dev/null`

13785 (at-devnull): Rename as...

13787 (--clean): Remove AT-* files too.

13823 * lib/autotest/general.m4 (AT_INIT): Log the command line.
13824 Support `VAR=VAL' as arguments.

13844 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as

13846 readable.
13847 Adjust callers.
13848 * doc/autoconf.texi (Configuration Actions): Document the vars
13849 available in commands.
13850 Emphasize the risks of collisions in init-cmds.

14302 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14303 * doc/autoconf.texi (C Compiler Characteristics): Update
14304 documentation for AC_C_BIGENDIAN.
14306 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14308 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
14309 magic values from an object file when cross-compiling.
14310 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14312 2001-08-10 Akim Demaille <akim@epita.fr>
14314 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14315 effects.
14316 Suggested by Russ Allbery.
14318 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14320 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14321 current $prefix to the sub-configures.
14323 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14325 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14326 extension (needed on BeOS). Reported by Guido van Rossum.
14328 2001-08-09 Akim Demaille <akim@epita.fr>
14330 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14332 2001-08-07 Akim Demaille <akim@epita.fr>
14334 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14335 removed.
14336 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14337 No need to remove the files before and after the each test, before
14338 each test and at the end of the suite is enough.
14339 Display only the children `times', not the shell's.
14340 If the test failed or was skipped, at-times is not available.
14342 2001-08-07 Akim Demaille <akim@epita.fr>
14344 Always produce testsuite.log, including when there are no
14345 failures. This helps getting information on skipped tests, and
14346 duration of the tests. Err, implement the latter btw.
14348 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14349 Dump information on the first run of each test.
14350 (AT_CLEANUP): Create `at-times' containing the duration of the
14351 test group.
14353 2001-08-07 Akim Demaille <akim@epita.fr>
14355 The use of `dumpstat' revealed that `len' was used although it
14356 should not. m4_text_wrap was using it, but in the Autoconf world
14357 where it is legal. Hence (i) test M4sh in its own world, not
14358 Autoconf's, and (ii), ahem, fix the bug :)
14360 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14361 does not like `' instead of [].
14362 (AT_INIT): Forbid `^_?AT_'.
14363 And don't output such tokens.
14364 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14365 `script.as', and `autom4te.cache'.
14366 Remove `empty' and `macro' which are no longer used.
14367 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14368 * tests/m4sugar.at: Use it.
14369 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14371 2001-08-07 Akim Demaille <akim@epita.fr>
14373 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14375 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14377 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14379 2001-08-04 Akim Demaille <akim@epita.fr>
14381 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14382 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14383 AC_TRY_LINK.
14384 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14385 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14386 (AC_F77_MAIN): Likewise.
14388 2001-08-04 Akim Demaille <akim@epita.fr>
14390 Don't rely on M4sugar outputting the patterns in files, since we
14391 might process the output _without_ running m4, hence without these
14392 files.
14394 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14395 * bin/autom4te.in (@Request::includes): Remove, unused.
14396 (@Request::source): Rename as...
14397 (@Request::input): this.
14398 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14399 (&handle_output): Fetch the patterns from the traces.
14400 `$forbidden' and `$allowed' are constant: use m//o.
14401 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14402 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14404 2001-08-04 Akim Demaille <akim@epita.fr>
14406 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14407 autoconf', i.e., in addition to caching traces, cache the output.
14409 * bin/autom4te.in (Request::cache): Rename as...
14410 (Request::id): this.
14411 ($cache, $icache, $tcache, $ocache): New.
14412 (&handle_m4): Save M4 output in the cache instead of $tmp.
14413 (&handle_output): Adjust.
14414 (&up_to_date_p): Check that the output cache is up to date too.
14415 (top level): Run `&handle_m4' iff force or the cache is invalid.
14416 Run `&handle_output' if the output cache is more recent.
14418 2001-08-04 Akim Demaille <akim@epita.fr>
14420 * bin/autom4te.in ($force): New.
14421 (&parse_args, &print_usage): -f, --force is a new option.
14422 (&handle_output): CPP directives might have spaces after `#'.
14423 (&parse_args): The first file only can be frozen.
14425 2001-08-04 Akim Demaille <akim@epita.fr>
14427 Don't let autom4te compute the `include' traces several times:
14428 first check that the trace cache file is up to date, and then
14429 compare its timestamp with that of the output.
14431 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14432 the preamble. Don't require 5.005 as Autom4te::General does it,
14433 and better yet (use `use', not `require'!).
14434 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14435 Class::Struct as Autom4te::Struct.
14436 * lib/Autom4te/General.pm (File::stat): Use it.
14437 (&mtime): New, export it.
14438 * bin/autom4te.in: Use it.
14439 Declare `$req' is invalid if it is outdated.
14440 Don't declare it valid before saving it if something went wrong.
14442 2001-08-04 Akim Demaille <akim@epita.fr>
14444 Autom4te shall not encode Autoconf data, and preselecting traces
14445 must be proposed to the users.
14447 * bin/autom4te.in (@required_trace): Remove.
14448 (@preselect): New.
14449 (&parse_args, &print_usage): -p, --preselect is a new option.
14450 (&up_to_date_p): Adjust.
14451 * bin/autoconf.in: Preselect some Autoconf macros.
14453 2001-08-04 Akim Demaille <akim@epita.fr>
14455 * tests/tools.at (autoconf --trace: user macros): Check traces on
14456 macros invoked without arguments, and macros invoked with multiple
14457 lines arguments.
14459 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
14461 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
14462 arguments.
14464 2001-08-03 Akim Demaille <akim@epita.fr>
14466 * bin/autoconf.in ($@): Work around the usual sh bug.
14467 From Nicolas Joly.
14469 2001-08-03 Akim Demaille <akim@epita.fr>
14471 Clean up the handling of the M4 builtins tracing exception.
14473 * bin/autom4te.in (Request::request): Don't complete M4 builtins
14474 trace requests.
14475 (@m4_builtins): Rename as...
14476 (@m4_builtin): this.
14477 (%m4_builtin_alternate_name): New.
14478 (&parse_args): Complete the trace requests with alternate names.
14479 (&handle_traces): Hence no longer do it here.
14480 (&trace_requests): Remove, unused.

14484 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
14485 m4_if, and m4_wrap.

14489 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
14490 (m4_divert_pop): Dump the whole diversion stack when a diversion
14491 mismatch happens.
14492 * bin/autom4te.in (&handle_output): Remember of the first
14493 occurrence of a possibly undefined macro, not the last.
14494 Complain about the possibly undefined macros in the same order as
14495 the appear in the output.
14496 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
14497 * tests/tools.at (autoconf: forbidden tokens, basic)
14498 (autoconf: forbidden tokens, exceptions): No longer sort
14499 autoconf's stderr, as it is now deterministic.
14500 Check that `dnl' is caught.
14502 2001-08-01 Akim Demaille <akim@epita.fr>
14504 * configure.ac: Bump to 2.52c.

14519 `die'.

14521 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
14522 `END', as `Autom4te::General::END' will be triggered.
14523 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
14524 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

14959 cross-language link tests can be performed successfully.
