3957 Pull in recent maintainer improvements from coreutils.
3958 * GNUmakefile (_is-dist-target): 'make distclean' should not

3963 * configure.ac (AC_CONFIG_LINKS): Copy GNUmakefile into VPATH
3964 builds, after initial bootstrap.

4035 (autotools and whitespace in file names): Use them.
4036 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4037 Cover more potentially problemtic file names. Use the new
4040 Properly handle funny file names for headers in config.status.
4041 The test suite did not cover this bug because the code was not
4042 quoting properly the arguments of `rm -f' (which "fails" silently)
4043 as well as the arguments of `diff' (whose output was redirected to
4044 /dev/null so we couldn't see its error message).
4045 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
4046 file names passed to `rm' and `diff'.
4047 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

4157 not just when atconfig was located.
4159 Add 'testsuite -C dir'.
4160 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
4162 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
4164 <DEFAULTS>: Delay computation of variables based on $at_dir...
4165 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
4166 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
4167 <PARSE_ARGS>: Parse new option.
4168 <HELP_TUNING>: Document it.
4169 * tests/autotest.at (Choosing where testsuite is run): New test
4171 (Keywords and ranges): Add test for missing -k argument.
4172 * NEWS: Document this.
4173 * doc/autoconf.texi (testsuite Invocation): Likewise.
4175 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4184 * doc/autoconf.texi (Particular Programs): Do not mention the
4185 Autoconf version in which the AC_PROG_INSTALL change was done.
4186 Suggested by Paul Eggert.
4188 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4190 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4191 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4192 mode, we change to the source directory, also set $ac_pwd so we
4193 do not go back to the build tree for the next config subdir.
4194 * tests/torture.at (Deep Package): Extend test to contain two
4195 config subdirs on the top level.
4197 Fix parallel `maintainer-check'.
4198 * Makefile.am (maintainer-check-tests): Depend on `all'.
4199 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
4200 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
4202 (maintainer-check): Serialize the testsuite runs.

4230 to use them for the manpages.
4231 Report by Benoit Sigoure.

4249 (m4_require): Use m4_do, not m4_join.
4251 Fix some whitespace tests on cygwin.
4252 * tests/tools.at (autom4te and whitespace in file names): Restore
4253 font-lock. Create $TMPDIR before it might be used.
4255 Fix spurious testsuite failure with M4 1.4.11.
4256 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4258 Optimize AC_REQUIRE.
4259 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4260 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4261 (m4_require): Avoid extra macro calls.
4263 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4265 * tests/torture.at (srcdir): Fix quoting.
4267 Do not pass top_srcdir to configure scripts in testsuite.
4268 * tests/autotest.at (srcdir propagation): Copy install-sh to
4270 (my only test): Drop setting of `top_srcdir'.
4271 * tests/base.at (Input/Output): Likewise.
4272 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
4273 config.guess, and config.sub to test source tree.
4274 Drop AC_CONFIG_AUX_DIR setting.
4275 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
4276 * tests/torture.at (Substitute a 2000-byte string): Drop
4277 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
4278 (Substitute a newline, datarootdir workaround): Likewise.
4279 (Define a newline): Adjust for linenumber changes in configure.ac.
4280 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

4287 * tests/tools.at (Syntax of the shell scripts): Likewise.
4289 * tests/m4sh.at (LINENO): Quote $0.
4291 Fix testsuite program wrapper for whitespace in `pwd`.
4292 The problem here is that the usual mantra is that command
4293 variables can contain arguments, thus we cannot just escape
4294 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4295 $top_builddir/tests directory early in $PATH, so that the
4296 wrappers are found by their plain name.
4297 * tests/wrapper.as: Put $testdir early in $PATH.
4298 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4300 Proper config.status --file/--header and $srcdir escaping.

4310 <at_func_create_debugging_script, Driver Loop>:
4311 Quote $at_group_dir.
4312 * tests/autotest.at (whitespace in absolute testdir): New test.
4314 * lib/autom4te.in: Quote @datadir@.
4316 Proper file name escaping in Autoconf programs and Perl modules.
4317 This includes escaping of characters special to the shell
4318 as well as special to Perl, e.g., leading `<' or `>'.
4319 For example, when $file starts with `>', `open ">$file"'
4320 wrongly tries to append to a different file.
4321 * bin/autoconf.as: Fix quoting for autom4te options.
4322 * lib/Autom4te/General.pm (shell_quote): New function, taken
4323 from coreutils, written by Jim Meyering.
4325 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

4331 * bin/ifnames.in: Likewise, XFile usage fixes.
4332 * tests/tools.at (autom4te and whitespace in file names): Extend
4333 test. Test twice, with special characters allowed on w32, and the
4334 rest. Test leading and trailing whitespace, for `open_quote'.
4335 (autotools and whitespace in file names): New, analogous test.
4336 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4337 by Russ Allbery and Eric Blake.

4341 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4342 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4343 (update_file, contents): Use it.
4345 * Makefile.am (autom4te-update): Rewrite for git.
4347 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4349 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4351 Fix copyright years.
4352 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4353 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

4365 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4367 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4368 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4369 #undef as this runs afoul of our new way of creating config.h.
4370 Problem reported by Jim Meyering in
4371 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

4375 Fix autom4te for unusual characters in input file names.
4376 * bin/autom4te.in (files_to_options): Quote active characters
4378 * tests/tools.at (autom4te and white space in file names):
4381 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
4382 Document that Tru64 awk always splits $0.
4384 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4386 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4387 `#AT_STOP_...' line at the end of each test.
4389 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4391 * lib/autotest/general.m4 (AT_INIT): For awk line number
4392 extraction script, ensure `$at_group' has a defined value
4393 even for the empty set, and properly quote its usage inside
4396 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4398 * doc/autoconf.texi (Shell Functions): New chapter. Document
4399 IRIX sh $0 issue in functions, move content from ...
4400 (Portable Shell): ... here.
4401 (Shell Script Compiler): Note that shell functions are not
4402 totally unportable any more.
4404 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4405 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4407 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4408 extracting the line numbers of the last needed test.
4410 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4415 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4417 Fix IRIX testsuite debugging failures: $0 in functions.
4418 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4419 Do not use $0 inside a function, as IRIX sh will set that to the
4420 function name rather than the script invocation name.
4422 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4423 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4425 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4426 to extract test scripts.
4427 (AT_INIT): Extract and cache test script line numbers.
4429 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4431 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4432 subsequent fixups; the awk -> here-document conversion trashes
4433 performance too much with AIX sh.
4435 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4437 * tests/local.at: Do not test m4, perl with AT_TESTED.
4439 Diagnose and guard against write errors dealing with config.status.
4440 The general idea is this: all write failures from `configure'
4441 writing `config.status' are indicated by $ac_write_error, which
4442 is only checked at the end. This is safe because config.status
4443 code is not executed before the file is complete. Other write
4444 failures, be they inside config.status, or in sub shell/awk
4445 scripts spawned from configure or config.status, typically need
4446 earlier checking, as their results are used right afterwards.
4447 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4448 before writing config.status, check afterwards.
4449 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4450 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4451 Set `ac_write_error' for write failures to config.status. Barf
4452 upon write failures to temporary files.
4453 Adjust note about closing and reopening the here-document.
4454 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4455 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4456 reopening the here-document.
4457 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4458 Ensure `ac_write_error' does not escape into config.status.
4459 Also, add a couple of code paths not yet exercised in the test
4460 suite: a config file with input from stdin, and a config header
4462 Suggestion for catching write errors by Bruno Haible.
4464 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4466 Avoid error with Tru64 awk and testsuite lines with many words.
4467 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4468 reads the testsuite, set the field separator to an unusual value,
4469 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4470 even splits the input if $i, i>0, was never accessed in the script.
4472 Revert 2007-10-17 change.
4473 * TODO: Multiline args in config files and headers mean something
4474 different and are not fixed, see

4480 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4482 AC_*_TOOL does not canonicalize the prefix
4483 * doc/autoconf.texi (Generic Programs): Do not say that
4484 the *_TOOL macros canonicalize, they simply use the `host_alias'.

4488 Diagnose write errors in config.status instantiations.
4489 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4490 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4492 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

4494 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4495 Report by Bruno Haible.
4498 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4500 (_AT_CHECK): Use less indentation, to save space.
4502 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4504 Add witness macro for @top_build_prefix@ substitution.
4505 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4506 (_AC_OUTPUT_FILE): Mention it here.
4508 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4509 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4511 * lib/autotest/general.m4 (at_func_test): Remove.
4512 (AT_INIT): Pre-extract test groups into separate files.
4513 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4514 Remove at-test-source files together with the $at_group_dir.
4515 * tests/autotest.at (Long test source lines): New test.
4517 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4519 Shell functions and variables may share a namespace.
4520 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4523 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4525 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4528 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4530 * lib/autoconf/status.m4: Fix a couple of comment typos.
4532 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4534 2007-11-13 Jim Meyering <meyering@redhat.com>
4536 Clean up the rule to create "expr".
4537 * tests/Makefile.am (expr): Don't redirect directly to target.
4538 Redirect just once, not for each echo statement.
4539 Use $@, not literal "expr".
4541 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4543 Don't worry about preprocessor when testing long long.
4544 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4545 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4546 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4547 These no longer check for preprocessor flaws.
4548 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4549 Do not check for preprocessor flaws.
4551 2007-11-13 Jim Meyering <meyering@redhat.com>
4553 Adapt dependencies, now that a version change doesn't modify configure.ac
4554 * GNUmakefile: Remove "make clean" kludge.
4555 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4557 Don't redirect directly to target.
4558 Use $@, not literal "version.m4".
4560 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4562 * doc/autoconf.texi (Making testsuite Scripts): Document
4563 ":;{" shorthand as in previous patch.
4565 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4567 * doc/autoconf.texi (Limitations of Builtins): Document problem
4568 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4570 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4571 Use ":;{" shorthand.
4572 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4574 2007-11-12 Jim Meyering <meyering@redhat.com>
4576 Add more non-srcdir build support.
4577 * GNUmakefile (dummy): Split a long line.
4578 Add -v option to autoreconf invocation.
4580 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4581 * GNUmakefile (dummy): Remove INSTALL.
4583 Remove racy commands to build scripts in bin/ and tests/.
4584 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4585 are guaranteed to be built, remove the rules that tried to build
4586 them. Before, with a parallel build, these rules could lead to
4587 two processes writing tests/wrapper.in concurrently.
4589 Build in man/ only *after* building in bin/ and tests/.
4590 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4591 in both bin/ and tests/.
4593 Accommodate non-srcdir build-from-checkout.
4594 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4595 Use git's --git-dir=$srcdir/.git option.
4596 Add quotes, in case tarball_version_file contains shell meta-characters.
4597 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4598 * configure.ac: Pass "." to git-version-gen.
4600 Avoid spurious test failures due to version skew.
4601 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4603 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4605 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4606 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4607 Remove conftest.dSYM directory.
4608 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4609 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4610 Remove `conftest.*' recursively.

4612 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4614 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4616 Report and analysis by Jeff Squyres and Peter O'Gorman.
4618 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
4620 Fix typos in variable names.
4621 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4623 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4625 Document that $((expression)) is not portable.
4626 * doc/autoconf.texi (Shell Substitutions): Here.
4628 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4630 Ignore configure --help* errors due to LINENO-impaired shells.
4631 * tests/torture.at (Configuring subdirectories, Deep Package):
4632 In the --help* tests in read-only trees, make `.' temporarily
4633 writable again for the `stderr' file, and ignore errors due to
4634 the attempt to write configure.lineno.
4635 Report by Patrick Welche.
4637 2007-11-10 Jim Meyering <meyering@redhat.com>
4639 Generate package.m4 in build-dir, not srcdir.
4640 * tests/Makefile.am (package.m4): Adjust target.
4641 Don't redirect directly to $@.
4642 (CLEANFILES): Add package.m4.
4643 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4645 When running $(AUTOTEST), search "." before searching $(srcdir).
4647 Avoid a race condition that would make parallel "distclean" fail.
4648 * tests/Makefile.am (distclean-generic): Replace the default,
4649 automake-provided rule with an identical one, but with an additional
4650 dependency on distclean-local. Simply adding the dependency would
4651 cause automake not to emit the rule at all.
4652 * BUGS: Building with -jN works, now.
4654 Distribute git-version-gen.
4655 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4656 since GNUmakefile is distributed, and requires it for dist* rules.
4658 Remove two more generated files from version control.
4659 * INSTALL: Remove generated file.
4660 * lib/autoscan/autoscan.list: Remove generated file.
4662 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4664 * GNUmakefile (PATH): Remove stray apostrophes; they become
4665 part of PATH, which isn't wanted here.
4667 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4669 New config files output variable `top_build_prefix'.
4670 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4672 * doc/autoconf.texi (Preset Output Variables): Document it.
4674 Report by Bob Friesenhahn.
4676 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4677 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4678 function, to parametrize arithmetic with expr vs. the shell.
4679 Use it where possible.
4680 Suggestion by Benoit Sigoure.
4682 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4684 Adjust the documentation of autotest WRT atlocal.
4685 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4686 when using Automake, to write a rule to produce atlocal, since it's
4687 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4688 distributed, not atconfig.in.
4690 2007-11-04 Eric Blake <ebb9@byu.net>
4692 Update list information.
4693 * README: Mention new autoconf-commit list.
4694 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
4696 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4698 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
4700 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
4702 * build-aux/.gitignore: Ignore mkinstalldirs.
4704 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
4706 2007-11-03 Jim Meyering <meyering@redhat.com>
4708 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4709 * build-aux/git-version-gen: This syncs from coreutils.
4711 Adjust the build procedure so "make check" works reliably.
4712 * README-hacking: Include an extra step between "make" and
4713 "make check" to ensure that the latter passes.
4715 Use just-built tools, when possible.
4716 * GNUmakefile (PATH): Set and export here, ...
4717 (dummy): ... rather than here.
4719 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4720 and Andreas Schwab <schwab@suse.de>
4722 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
4725 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4727 * configure.ac (AC_PREREQ): Require version 2.60, for
4728 AC_PROG_SED, AC_PROG_GREP.
4730 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
4731 and Jim Meyering <meyering@redhat.com>

4745 Reported by Ralf Wildenhues.
4747 2007-11-03 Jim Meyering <meyering@redhat.com>
4749 Remove automake-provided files from version control.

4751 * build-aux/install-sh: Remove file.
4752 * build-aux/missing: Remove file.
4753 * build-aux/mdate-sh: Remove file.
4754 * build-aux/.gitignore: New file.
4755 Suggestion from Ralf Wildenhues.
4757 2007-11-03 Eric Blake <ebb9@byu.net>
4759 Adjust version comparison to account for git snapshot numbers.
4760 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

4763 <m4_version_compare>: Document this change.
4764 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
4766 2007-10-30 Bruno Haible <bruno@clisp.org>
4768 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
4769 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
4770 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
4771 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
4772 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
4773 Suggested by Paul Eggert.
4775 2007-10-28 Jim Meyering <meyering@redhat.com>
4777 * README-hacking: Autoconf, Automake, and Perl are required to build.
4778 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
4780 2007-10-28 Jim Meyering <meyering@redhat.com>
4782 README-hacking: Recommend running autoreconf -vi.
4783 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
4784 so that we use just-built tools when they're available.
4785 Suggestions from Ralf Wildenhues.
4787 2007-10-28 Jim Meyering <meyering@redhat.com>
4789 Make inter-release --version output more useful.
4791 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4792 which indicates that it is built using the 19th change set
4793 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4794 is a prefix of the commit SHA1.
4795 * build-aux/git-version-gen: New file.
4796 * configure.ac: Run it to set the version.
4797 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4798 * Makefile.am (dist-hook): Arrange so that .version appears only
4799 in distribution tarballs, never in a checked-out repository.
4800 * .gitignore: Add .version here, too. Just in case.
4801 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4802 not configure.ac, now that the version number changes automatically.
4804 Ensure that $(VERSION) is up to date for dist-related targets.
4805 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4806 git-version-gen doesn't match $(VERSION), but only for dist targets.
4808 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4848 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
4850 Don't check for bug in HP-UX 11.00 cpp.
4851 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
4852 Use -1ull rather than -1u, since that causes problems with gnulib; see
4853 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

4877 this resolution. Fixes test failure on FreeBSD.
4879 Fix config header generation with AIX awk.
4880 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
4881 script, use helper array D_is_set, as `" 0"' does not evaluate

4923 array of banner text from a special diversion.
4924 <PARSE_ARGS_END>: No longer need awk to find banners.
4925 <TESTS>: Banners are no longer processed by main driver loop, so
4926 we no longer need case statement.

5957 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
5958 choice, since that's what we do with --enable-largefile etc.
5959 Redo indenting and assignments to simplify things a bit, and make
5960 the parens work with Emacs.

6062 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
6063 for a.* when searching for executables, as this prevents users

6077 AC_CHECK_TYPE, AC_CHECK_TYPES.
6078 * doc/autoconf.texi (Generic types): C types must be type-names
6079 (the C terminology), not type-ids (the C++ term). C++ types
6080 must not be anonymous.
6081 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
6082 for C++; this drops support for anonymous struct and union types,
6083 which were problematic anyway.

6102 with objects too. Document the restrictions on its use.
6103 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6104 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6105 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6106 works but the latter doesn't, then it's a valid type.
6107 This lets people use function types and so forth.
6108 For C++ there doesn't seem to be a simple solution, so leave it alone.
6109 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6110 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
6111 AC_CHECK_TYPE; that wasn't documented or necessary.
6113 2007-04-11 Stepan Kasal <kasal@ucw.cz>
6115 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

6166 2007-03-17 Jim Meyering <jim@meyering.net>
6168 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
6169 (Limitations of Usual Tools): Also list \< and \>, and mention that
6170 HP-UX's grep, like the one from Solaris, does not support that syntax.
6172 2007-03-09 Stepan Kasal <kasal@ucw.cz>

6281 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
6282 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6283 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6284 substitution will still be done by the special code.

6308 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6309 early on the reader side, drop stderr of the input to avoid
6310 `broken pipe' error output; this may happen even with shell
6311 builtin `echo' of some bash versions. Reports by Ian Macdonald

6329 discussion about the allow_superuser_privileges example,
6330 and change it a bit to make things clearer.
6331 (Optimization and Wraparound): Clarify whether the compiler
6332 will generate an infinite loop for the example derived from
6333 Autoconf's mktime test.
6334 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6335 Also, clarify unsigned multiplication overflow.
6337 2007-01-04 Eric Blake <ebb9@byu.net>
6339 * bin/Makefile.am (RELEASE_YEAR): New macro.
6340 (edit): Use it to supply correct copyright year to scripts.

6349 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6351 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6352 feedback. The most important changes document what happens when
6353 you convert an out-of-range value to a signed integer type, and
6354 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6357 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6358 rewrite, taking notions from the recent discussion on the gcc and
6359 autoconf mailing lists; please see
6360 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6361 and follow the many links.
6362 (Integer Overflow Basics, Signed Overflow Examples):

6364 (Signed Integer Division): New sections.
6366 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6368 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6369 preprocessor macro arguments in traced name.
6370 * doc/autoconf.texi (Defining symbols): Document longstanding
6371 support for AC_DEFINE-ing macros with arguments, and document
6372 behavior when the same variable has multiple AC_DEFINEs.
6373 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6374 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6375 macros directly, giving much shorter and simpler code.
6377 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6379 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6380 space before "$ac_configure_args" to prevent a 'config.status
6381 --recheck' failure if ac_configure_args doesn't contain a leading
6382 space. This works around a problem with the XEmacs configure.ac,
6383 which uses the (undocumented) ac_configure_args variable
6384 inconsistently with Autoconf.
6386 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6388 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6389 Include <limits.h>, and use its INT_MAX to rewrite the
6390 j loop so that it does not overflow 'int'. Problem reported by
6392 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6393 Play it safe by shifting left by 1 rather than multiplying by 2,
6394 as GCC is less likely to optimize this away when the value
6395 is signed (when it assumes overflow leads to undefined behavior).
6396 Also, don't assume time_t uses two's complement.
6398 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6400 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6401 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6402 dumps core on it. Report by Tim Rice.

6417 * NEWS: Warnings are now generated by default for unknown
6418 --enable-* and --with-* options.
6419 * doc/autoconf.texi (Option Checking): Renamed from
6420 (Configure Option Checking). Tighten up the wording a bit.
6421 (External Software, Package Options): Cross-reference to Option
6422 Checking, and use this to shorten our section.
6423 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6424 "$x" to test "x$foo" != x.
6425 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6426 Don't warn if $enable_option_checking is "no".
6427 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6428 ac_unrecognized_opts to the empty string.
6429 Don't echo the unrecognized opts, as this might mishandle
6430 backslashes or leading -.
6431 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6432 usage next to the other --disable-FEATURE options in the
6435 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6437 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6438 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6439 Print warning for unrecognized --with and --enable options
6440 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6441 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6442 Disable option checking when subdirs are configured.
6443 (AC_OUTPUT): If warnings are enabled, print warning about
6444 unrecognized --with and --enable options at the end of
6445 the configure output (as well as at the beginning).
6446 * doc/autoconf.texi (Option Checking): New node.
6447 Document new option warning functionality.
6449 2006-12-16 Eric Blake <ebb9@byu.net>
6451 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6452 * NEWS: Start news for current version.
6454 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6456 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6457 Define HAVE_GETMNTENT to 1, not to the empty string.
6458 Problem originally reported by Jochen Friedrich in
6459 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6461 This change prompted by a problem report by Andrey Simonenko in
6462 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6463 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6464 object-like macros only, in the traditional portable character
6466 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6467 Warn about attempts to define things that are not identifiers.
6468 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6469 awful hack that AC_DEFINEd macro names containing parentheses.
6471 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6473 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6474 too drastic, even if Texinfo in theory requires it for info mode.
6476 (config.status Invocation): Renamed back from Recreating a
6478 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6479 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6481 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6483 * NEWS: Version 2.61a.
6485 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6486 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6488 * NEWS: Document changes with echo and printf, and the lack
6489 of limits on the total size of multi-line values of substituted
6490 variables, and the AC_FUNC_FSEEKO fix.
6492 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6494 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6495 Writing configure.ac.
6496 (Autoconf Input Layout): Renamed from configure.ac Layout.
6497 (Recreating a Configuration): Renamed from config.status Invocation.
6498 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6499 (acconfig Header): Renamed from acconfig.h.
6500 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6501 (Writing Testsuites): Renamed from Writing testsuite.at.
6502 (Autom4te Cache): Renamed from autom4te.cache.
6504 * BUGS: Remove mention of VPATH problem, since it's now documented
6505 not to be a bug in the Autoconf build procedure itself, but rather
6506 a problem with the proprietary `make' programs.
6508 * doc/autoconf.texi (Build Directories): Add a cross reference
6511 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6512 * doc/standards.texi: Sync from gnulib.
6514 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6515 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6516 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6517 generated automatically.
6519 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6521 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6522 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6523 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6525 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6527 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6528 `CEOF$ac_eof' special marker, the awk script cannot contain a
6529 line matching `^CEOF', so this is not needed any more.
6530 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6531 special marker in the test.
6533 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6535 * tests/tools.at (autom4te preselections): Use `find -newer';
6536 remove one of the sleeps.
6538 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6539 more readable, using ...
6540 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6542 * doc/autoconf.texi (autoheader Invocation): Do not double-
6543 quote the parameter of `AH_BOTTOM' in the example.
6545 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6547 * doc/autoconf.texi (Configuration Headers): Remove the
6548 example with multiple input files.
6549 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6550 multiple input files.
6552 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6554 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6555 creating the awk substitution script, handle one input line at a
6556 time, so that the maximum length of a substituted (multi-line)
6557 value is not limited by the size of the sed pattern space.
6558 The trade-off is a slightly repetitive sed script.
6559 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6560 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6561 * tests/torture.at (Substitute a 2000-byte string): Increase the
6562 test with several long lines, they should not be caught by sed
6565 * tests/tools.at (autom4te preselections): New test, to flag
6566 entries missing from autom4te.cfg.
6567 Report by David Byron <dbyron@hheld.com>.
6569 * tests/torture.at (Substitute a 2000-byte string): Actually use
6570 AC_PROG_AWK, so the last change works as intended.
6571 (Substitute and define special characters): Likewise.
6572 (Substitute a newline): Likewise.
6574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6575 instead of `awk' consistently.
6576 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6577 * tests/torture.at (Torturing config.status): Test both the
6578 result of AC_PROG_AWK and plain awk.
6579 (Substitute a 2000-byte string): Likewise.
6580 (Substitute and define special characters): Likewise.
6581 (Substitute a newline): Likewise.
6583 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6585 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6586 can be assigned to a function pointer. Problem reported by
6587 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6588 part of a patch by Ralf Wildenhues in that same bug report.
6590 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6592 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6593 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6595 2006-12-01 Eric Blake <ebb9@byu.net>
6597 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6598 cross-compiling from cygwin to mingw.
6599 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6600 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6601 to lib/autoconf/c.m4.
6603 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6605 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6606 string for more reliable failure. Wrap the entire test that
6607 causes the broken Solaris printf to dump core, in a subshell,
6608 so the segmentation fault message is reliably suppressed.
6609 Fix shell expansion errors by using /usr/ucb/echo always;
6610 avoid an error on systems without it by another subshell.
6611 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6612 subshell-$as_echo to `as_echo', for better error message.
6614 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6616 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6617 `BASH_SOURCE' contain a newline, set them to empty, as they may
6620 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6622 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6623 years and is too hard to maintain now. The last straw was
6624 reported by Jerker Baeck in
6625 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6626 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6627 * doc/autoconf.texi (Particular Functions): Move
6628 AC_FUNC_SETVBUF_REVERSED from here...
6629 (Obsolete Macros): ... to here. Say that it does nothing now.
6630 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6631 Turn into (almost) a no-op.
6633 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6635 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6636 These macros are obsolescent and new applications shouldn't need them.
6637 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6638 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

6643 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6644 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6646 * doc/autoconf.texi (Setting Output Variables): Mention that
6647 @VAR1@VAR2 has unspecified behavior. Problem reported by
6649 * NEWS: Mention this.
6651 * Makefile.am: Put only a single '#' into the copyright notice,
6652 so that it's also present in the output file. Standardize wording
6653 in makefile copyright notices to match GNU coding standards.
6654 * bin/Makefile.am: Likewise.

6667 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6670 in the sed script that mangles the awk script: delete up to the
6671 first exclamation mark only.
6672 * tests/torture.at (Substitute and define special characters):
6675 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6677 Rewrite config files generation: avoid quadratic growth in
6678 the number of substituted variables by using awk instead of sed
6679 for the bulk of the substitutions.
6680 * NEWS: Mention this.
6681 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6682 forbidden in the output (and thus input) file.
6683 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6684 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6685 generate just one large awk script for substitutions,
6686 eliminating much of the earlier complexity, while adding some
6687 new complexity. Only expand the substitution templates at
6688 configure time, for smaller configure script size. If
6689 _AC_SUBST_FILES are used, test 'awk' for working getline support
6690 at config.status time. If absent, interpolate through the
6691 shell. The awk script was written with much help
6692 from Paolo Bonzini and Paul Eggert.
6693 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6694 (_AC_SED_FRAG_NUM): Likewise.
6695 (_AC_SUBST_CMDS): Renamed from...
6696 (_AC_SED_CMDS): ...this.
6697 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6698 * tests/torture.at (Substitute a 2000-byte string): Also
6699 substitute a line with 1000 words, and a variable with several
6701 (Substitute and define special characters): Test awk special
6702 characters, and put substitution input strings `@foo@' in the
6703 output, to test that no recursion happens; test several other
6704 combinations from Paolo Bonzini.
6706 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6708 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6709 that replaced echo with AS_ECHO where this wasn't necessary.
6710 Problem reportd by Ralf Wildenhues.
6711 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6712 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6713 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6715 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6717 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6719 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6721 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6722 that traditional Awk lacks 3-arg "split". It has it.
6723 Mention that FS must be a single character, and a few other
6724 99-byte limits of traditional Awk.
6725 Mention that if (i in a) doesn't work with traditional Awk.
6727 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6729 * tests/autotest.at (BSx641-newline in command):
6730 (BS-BS-newline in command, BSx640-newline in command):
6731 (Newline-CODE-BS-newline in command):
6732 (Single-quote-BS-newline in command):
6733 (Single-quote-newline-BS-newline in command):
6734 Use printf '%s\n' instead of echo, for portability to hosts
6735 where echo interprets backslashes. This will break on hosts
6736 that lack printf, but for now let's assume all such hosts
6737 are dead (if not, we should get reports of test failures).
6739 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6741 'echo' has some portability problems, when given a first argument
6742 with a leading '-', or when given any argument containing '\'.
6743 Avoid using 'echo' in these cases.
6744 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
6745 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
6746 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6747 * lib/autotest/general.m4 (AT_INIT): Likewise.
6748 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
6749 argument might be unportable.

6768 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
6769 * bin/autoconf.as: Redo verbose flag implementation, as the old
6770 scheme wouldn't work with AS_ECHO.
6771 * lib/autotest/general.m4 (AT_INIT): Likewise.
6772 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6773 Don't use ECHO_T, since ECHO_N is now reliable.
6774 * lib/autotest/general.m4 (AT_INIT): Likewise.
6775 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6776 rather than using a here-document to put the script into a file.
6777 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6779 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6780 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6781 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6782 bug, but we might as well stop using ECHO_N and ECHO_C internally.
6783 * lib/autotest/general.m4 (AT_SETUP): Likewise.

6785 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6786 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
6787 operand, as AS_ECHO requires. Avoid double file name expansion.
6788 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6789 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
6790 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
6791 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
6792 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
6793 Double-quote strings that would otherwise contain M4 comments.
6794 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
6796 * configure.ac (AC_INIT): Bump to 2.61a.
6799 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6803 * configure.ac (AC_INIT): Bump to 2.61.
6806 * tests/autotest.at (Macro with backslash in a test title):
6807 Comment out for now, as this tests neither fails nor passes
6808 reliably. Problem reported by Ralf Wildenhues.
6810 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
6812 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
6813 in previous change, which caused test failures.
6815 2006-11-16 Stepan Kasal <kasal@ucw.cz>
6817 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
6818 code for --enable, --disable, --with, and --without to...
6819 (_AC_INIT_PARSE_ENABLE): ... a new macro.
6820 * doc/autoconf.texi (Package Options):

6825 Import these changes from config via gnulib:
6827 2006-11-15 Ben Elliston <bje@gnu.org>
6829 From Josselin Mouette <joss@debian.org>:

6843 Import this change from coreutils:
6845 2006-02-13 Jim Meyering <jim@meyering.net>
6847 * GNUmakefile (all): Emit diagnostics to stderr, not stdout.
6850 Import this change from gnustandards via gnulib:
6852 2006-11-15 Karl Berry <karl@gnu.org>
6854 * standards.texi: core -> memory, throughout.
6855 (CPU Portability): show correct example of calling write
6856 on a char value; thanks to Paul Eggert for the code.
6857 Both of these suggestions from Eugene Y. Vasserman.
6860 Import these changes from texinfo via gnulib:
6862 2006-11-08 Karl Berry <karl@gnu.org>

6900 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
6901 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

6933 Single-quote in a test title,
6934 Double-quote in a test title): Don't expect failure anymore.
6935 (Backslash in a test title): Put a non-whitespace character after the
6936 backslash so that Bourne shells might actually see it as an escape

6945 Macro with double-quote in a test title,
6946 Macro with backslash in a test title): New tests expected to fail.
6947 * tests/torture.at (#define header templates): M4-quote this title in
6948 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
6949 The visible effect was a stray [] in the testsuite output.
6951 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6953 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
6954 `trap ... 0' inside a function, for AIX sh.
6956 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
6958 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6959 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6960 5363) simply issues a warning when dividing by zero at compile
6961 time. Problem reported by Elias Pipping.
6963 2006-10-26 Eric Blake <ebb9@byu.net>
6966 * doc/autoconf.texi (Evaluation Macros): Improve the example to

6995 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6996 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6997 reported by Nelson H. F. Beebe for Coreutils 6.4.
6999 * tests/tools.at (autoconf --trace: user macros): Remove test
7000 for tracing multiline macros, since m4 1.4.7a uses a different

7077 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
7079 (Imported from Automake.)
7080 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7081 which incorrectly sets the mode of an existing destination
7082 directory. In some cases the unpatched install-sh could do the
7083 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7084 system. We hope this is rare in practice, but it's clearly worth
7085 fixing. Problem reported by Alex Unleashed in
7086 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7087 Also, don't bother to check for -m bugs unless we're using -m;
7088 suggested by Stepan Kasal.

7137 added to the template can get mangled.
7139 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7141 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
7142 include the default headers, and redefine obstack_chunk_alloc
7143 and obstack_chunk_free. Fixes false failure with glibc.

7164 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
7165 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7166 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7167 Use a better substitute, by inspecting the output of "ls"
7168 rather than just using ":".
7169 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7170 rather than AS_EXECUTABLE_P, since we needn't worry about
7171 non-regular files here.
7173 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7174 due to configuration hassles with this. See Tonya Underwood's report

7198 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7199 comment about ac_cpp_err; it was incorrect, and anyway
7200 ac_cpp_err is being removed below.
7201 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7202 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7203 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7205 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7206 with werror_flag and conftest.err and so forth. This is more
7207 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7208 and anyway the user shouldn't normally want to see this gorp logged.
7209 Problem reported by Ralf Wildenhues.
7210 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7211 empty, not 'no', since the rest of the code uses 'test -z'.

7215 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7216 Use a single call to AC_DO_TOKENS rather than multiple, for
7218 (_AC_LINK_IFELSE): Test that resulting file is executable.
7219 Problem reported by mwoehlke in
7220 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7222 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7223 than creating a file to use with test -x; this is much faster.
7225 2006-10-02 Bruno Haible <bruno@clisp.org>
7227 * lib/autom4te.in (Automake-preselections): Add
7228 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7230 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7232 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

7239 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7240 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7241 still doesn't let the program compile.
7242 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7245 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7246 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7247 include it, without including anything else.
7248 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7250 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

7357 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
7358 for the existence of the directory at configure-time. That's
7359 too late, anyway. Problem reported by Stefan Seefeld.
7361 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
7362 7.1.4 /usr/bin/posix/sh described by Tim Rice in

7378 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
7379 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
7380 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

7403 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
7404 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
7405 accept files with extension `.f'. For consistency, also prefer

7428 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
7429 except the first two arguments are reversed.
7430 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
7431 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
7432 caches nor outputs a diagnostic. Suggested by Bruno Haible.

7477 for the default, which the user can override.
7478 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
7480 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
7481 didn't work if some values were cached but not others. Test for
7482 broken lex libraries like native ia64-hp-hpux11.22; see
7483 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
7484 work around the problem by preferring an empty LEXLIB to -lfl or
7485 -ll. Let the user set LEXLIB='' to indicate no library needed.
7487 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
7489 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

7590 * doc/autoconf.texi (Particular Programs): Mention that
7591 @INSTALL@ and @MKDIR_P@ may vary for different output files.

7612 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
7613 -Wundef -Werror". Problem reported by David Fang in

7637 problems with arg script text that doesn't end in newline, and

7640 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
7642 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

7674 less skeptical about "volatile", after discussion with
7675 Bruno Haible on bug-gnulib.
7676 (Limitations of Usual Tools): Warn about sed stripping
7677 leading white space from text. From Bruno Haible.

7686 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

7689 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
7691 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

7704 under AC_C_VOLATILE.
7705 (Volatile Objects): Be a little less skeptical about what
7706 "volatile" means. Derived from thoughts by Ben Pfaff in

7713 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
7715 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7716 more globally, since the 2006-06-30 patch didn't suffice. Problem
7717 reported by Keith Marshall. Also, don't bother with builddir2,
7718 since it shouldn't be needed any more.
7720 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
7722 * doc/autoconf.texi (Generic compiler characteristics):
7723 Document AC_COMPUTE_INT. Fix wrong statements on Default

7739 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7741 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7742 Require that long long int be at least 64 bits wide. C99 requires
7743 this and enough programs depend on it so we should check for it.
7744 Bruno Haible reports in
7745 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7746 that long long int is 32 bits wide with some nonstandard compilers.

7749 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7751 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7752 to a nonexistent file, so that we don't have to worry about
7753 a local site configuration that doesn't use /usr/local.
7754 Problem reported by Keith Marshall in
7755 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7757 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7759 * doc/autoconf.texi: Be more consistent about using @acronym with
7760 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7761 quite right (it talked about "OSF/Tru64", even though the
7762 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7763 and it even mentioned "OSF 4"!) and at this point there's little
7764 reason to talk about OSF any more, since it died in 1994.
7765 (Specific Compiler Characteristics): Simplify example of
7766 negative-size array.
7767 (File Descriptors): Reorder to make the text flow better.
7768 Remove joke about "appreciate the various levels"; I didn't get it.
7769 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7770 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7771 (File Descriptors, Limitations of Usual Tools):
7772 Tone down the advice against renaming or removing open files.
7773 (Limitations of Usual Tools): Add a new section, on 'rm'.
7775 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7777 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7778 -lXt in LIBS, idea from Karsten Hopp; this was due since
7781 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7782 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7783 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7784 (which belong to Xt, not X itself). See Debian bug 327655.

7795 * configure.ac, NEWS: Update.
7797 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7799 * config/texinfo.tex: Sync from upstream.
7801 * bin/autom4te.in (handle_traces): Transform the `@S|@'
7802 quadrigraph correctly in traces.
7804 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
7807 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
7808 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7810 * doc/autoconf.texi (Changed Directory Variables): New node,
7811 to document the whole `datarootdir' business a bit better.
7813 * tests/torture.at (datarootdir workaround): Extend test.
7814 Prompted by report by Alexandre Julliard.
7816 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7818 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7819 when using default mode of IBM C 6 for AIX. Problem and two-line
7820 fix reported by Larry Jones.
7822 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7824 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7825 about literal '${datarootdir}' if a definition is found in the
7828 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7830 * NEWS: Use "M4" rather than "m4" when appropriate.
7831 Problem reported by Eric Blake.
7832 * doc/autoconf.texi: Likewise.
7833 Use @acronym around BSD, GCC, and GNU when appropriate.
7834 (Why GNU M4): Renamed from "Why GNU m4".
7835 (Redefined M4 Macros): Mention that Posix
7836 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7837 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7840 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7842 * bin/autom4te.in (handle_output): Do not forbid the empty
7844 * tests/tools.at (autoconf: the empty token): New test.
7846 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7848 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7849 calls, so that we do not care whether they are LIFO or FIFO;
7850 in the m4_wrap, do not check which diversion is the topmost
7851 one, just check that the stack is balanced at the end.
7852 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7853 base diversion forever--pop the previous diversion before
7854 opening the new one; consequently, remove the m4_wrap call.
7855 * lib/autotest/general.m4 (AT_INIT): Likewise.
7856 * tests/m4sugar.at: Do not use
7857 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
7859 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7860 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7862 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7863 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7864 Rework example of m4wrap token-pasting trouble so that it doesn't
7865 care whether it's LIFO or FIFO.
7866 Fix some "contrary to"s that are awkward in English.
7868 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7870 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7871 to `yes' instead of `int$1_t' if the type is found, for more
7872 consistent configure output (where $1 is the number of bits).
7873 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7874 Suggested by Bruno Haible.
7876 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7877 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7878 with system headers. Report by Bruno Haible.
7880 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7882 * config/config.guess, config/config.sub: Sync from upstream.
7884 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7885 in order to avoid picking up an older installed frozen m4sh.m4f.
7886 Besides an outdated shell startup, this could have been created
7887 by an earlier M4 version with incompatible frozen file format.
7889 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7891 * README: Recommend m4 1.4.4 instead of 1.4.3..
7892 * doc/autoconf.texi: Likewise.
7893 (Special Chars in Names): Say that $(.FOO) is portable, as
7894 suggested by Stepan Kasal.
7895 (Installation Directory Variables, Build Directories):
7896 (Automatic Remaking, Subdirectories, Fortran Compiler):
7897 (Making testsuite Scripts, Defining Directories):
7898 Quote variable usages better.
7899 (Making testsuite Scripts): Add clean-local rule to makefile
7900 snippet, by Eric Blake.
7901 (Installation Directory Variables): Fix table item font.
7902 Reword slightly to clarify. Generalize advice about
7903 not using special characters to include all file-related
7904 vars, not just VPATH.
7905 (Special Chars in Variables): Warn about special characters in
7907 (Assignments): Clarify default-value example as suggested by
7909 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7910 (Special Shell Variables): Note leading ./ or ../, as suggested
7912 (Limitations of Builtins): Under cd, warn about CDPATH.
7913 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7916 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7918 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7919 `@var', for texi2html.
7920 (Systemology): Some more word wrapping, for DVI output.
7921 (autom4te Invocation): The short option for `--melt' is `-M',
7924 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7926 * doc/autoconf.texi: More formatting and English tweaks,
7927 many suggested by Ralf Wildenhues.
7928 Reword to avoid "@code{...}'s" and the like, since it's ugly
7929 with Emacs info mode. discontents -> woes.
7930 Put a few "will"s back. time stamp -> timestamp.
7931 side-effect -> side effect.
7933 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7935 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7936 Warn about $@ not persisting. Problem reported by Julien Danjou in
7937 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7938 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7939 Mention other special chars, too.
7941 2006-06-14 Eric Blake <ebb9@byu.net>
7943 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7945 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7947 * doc/autoconf.texi: Some systematic minor improvements, as
7948 follows. Use "makefile" when talking about makefiles
7949 generally (which might be named "makefile" or "Makefile" or even
7950 "foo.mk"), "Makefile" when talking about a specific makefile
7951 called "Makefile". This unclutters the text from weird quotes
7952 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7953 values" rather than "@var{foo}s" and similar constructs containing
7954 "}s". Use "Make rules" rather than "Makefile rules". Minor
7955 English-language improvements. Change the prefix "sub-" to "sub"
7957 Put blank lines around examples more consistently.
7958 Avoid "rather" and "very" as intensifiers.
7959 Avoid "will" as an auxiliary.
7960 (Limitations of Make): Split this node into....
7961 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7962 (Leading _ in Macro Names, Backslash-Newline-Newline):
7963 (Backslash-Newline Comments, Long Lines in Makefiles):
7964 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7965 (obj/ and Make, make -k Status, VPATH and Make):
7966 (VPATH and Double-colon, $< in Explicit Rules):
7967 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7968 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7969 New nodes, resulting from splitup of Limitations of Make.
7970 All cross-references changed. Raise the top node from
7971 a section to a chapter, and all subnodes accordingly.
7972 Redo the introductory wording to match the new organization.
7973 (Installation Directory Variables): Use an example that is
7974 closer to what Autoconf actually does. Mention that VPATH's
7975 value should not contain metacharacters or white space.
7976 (Fortran Compiler): Fix a VPATH bug in an example.
7977 (Leading _ in Macro Names): Mention that this problem is no longer
7978 of practical concern.
7979 (VPATH and Make): Reword the advice to make it clearer
7980 that Autoconf and Automake support VPATH in non-GNU make, but
7981 many packages have bugs in this area.
7982 ($< in Explicit Rules): Refer to Build Directories rather
7983 than using a (non-VPATH-safe) example.
7984 (Automatic Rule Rewriting): Mention the sort of disaster that
7985 can ensue with Solaris-style rule rewriting with VPATH.
7987 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7989 * doc/install.texi (Compilers and Options): Weaken the
7990 suggestion to use GNU make for VPATH builds.
7992 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7993 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7995 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7996 in regular expression.
7998 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8000 * doc/autoconf.texi (Installation Directory Variables):
8001 Drop extra @samp from `@table @samp' item.
8002 (Limitations of Usual Tools): Comment fix.
8003 Do not nest @samp just to point to other table items.
8004 (Writing testsuite.at) <AT_CHECK>: The second argument to
8005 `@dvar' is already @samp'ed.
8006 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8007 do not use @var in the second argument.
8009 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8011 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8012 $as_shell.exe too. Problem reported by Andreas Buening in
8013 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8015 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8017 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8018 `unused variable' compiler warning, for `-Wall -Werror'.
8019 Reported by Jaap Haitsma in
8020 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8022 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8024 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8025 case the compiler dumps core. Problem reported for
8026 OpenServer 5.0.7 by Tim Rice in
8027 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

8031 2006-06-06 Tim Rice <tim@multitalents.net>.
8033 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8034 "ERROR" only shows up in "make check" output if there is an

8058 * config/texinfo.tex: Sync from upstream.
8060 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8061 seen, invoke libtoolize with `--ltdl' argument.
8062 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8064 Suggested by Eric Blake.
8066 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8068 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
8069 reported by Ralf Wildenhues.

8086 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8088 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8090 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8091 `expout' as the last parameter.
8092 * tests/tools.at: Adapt to the above change.
8094 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8096 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8097 information about race-free implementations of mkdir.

8106 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8108 * NEWS: GNU make now recommended for VPATH builds.
8109 Mention that some macros are now documented to be obsolescent.
8110 * doc/autoconf.texi:
8111 Prefer "current" to "modern" to describe
8112 currently-used (albeit perhaps old-fashioned) hosts.
8113 Mention which ancient features no longer need to be worried about.
8114 setgid -> set-group-ID
8115 setuid -> set-user-ID (these are the Posix terms)
8116 Fix some misuses of "only".
8117 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8118 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
8119 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

8127 (Installation Directory Variables): shall -> should
8128 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8129 Mention that it's now safe to use 3 and 4.
8130 (Limitations of Usual Tools): cp -r is now specified by Posix.
8131 Omit longwinded and obsolescent discussion of cp -f.
8132 Modernize discussion of expr, ls.
8133 (Limitations of Make): Modernize discussion of VPATH builds.
8134 Mention $? as a workaround in some cases.
8135 * doc/install.texi (Basic Installation):
8136 Mention "./configure; make; make install" first. Be more
8137 specific about why this file is generic. Remove unnecessary
8138 parens. Remove misleading "only". Remove obsolete advice
8139 about csh. Don't say "configure" takes awhile; say it
8140 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8141 and CC=c99 rather than CC=c89, as these are blessed by current
8142 Posix. Recommend GNU make if doing a VPATH build.
8144 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8146 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8147 examples involving shell prompts.

8150 and Paul Eggert <eggert@cs.ucla.edu>
8152 * doc/autoconf.texi (Here-Documents): Add details about the
8153 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
8154 use "here-documents" instead of "here documents".

8186 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8188 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8189 about quoting ac_try: quote all of it, if any of it seems suspicious.
8190 This means we don't have to worry about ${ or sed any more.
8191 Also, double-quote the case statement, to work around misuses via
8192 underquoting as reported by Ralf Wildenhues in
8193 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8194 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
8195 undocumented and dangerous macro.
8196 Problem reported by Ralf Wildenhues in
8197 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
8199 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8207 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
8208 since evidently some packages rely on the old, broken behavior.
8209 Problem reported by Ralf Wildenhues in
8210 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8211 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8212 pre-2006-05-26 definitions, but leave in the comments that
8213 these macros are dangerous and should not be used.
8214 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8215 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8216 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8217 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8218 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8220 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8222 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8223 the use of 'tr', since this is our only use of 'tr'.
8225 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8226 and Paul Eggert <eggert@cs.ucla.edu>
8228 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8229 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8231 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8233 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8234 the output file in the `${datarootdir}' test.
8236 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8237 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8240 mention of `datarootdir' in the input file(s), but literal
8241 `${datarootdir}' in the output file, and we haven't warned yet,
8242 then warn as well: the user may have (erroneously) used
8243 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8244 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8245 * tests/torture.at (datarootdir workaround): Extend this test.
8248 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8249 and Paul Eggert <eggert@cs.ucla.edu>
8251 * doc/autoconf.texi (autoheader Invocation): The first argument to
8252 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8253 alternatives and clear up the language a bit.
8255 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8257 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8258 ac_config_guess, ac_config_sub, ac_configure.
8259 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8260 Fix typo that prevented an unnecessary space from being removed.
8261 Problems reported by Ralf Wildenhues in:
8262 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8264 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8266 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8267 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8268 Don't use the term "thread-safe" to talk about mkdir race
8269 conditions, since the problem is more a process than a thread
8270 issue. Problem reported by Stepan Kasal in:
8271 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8272 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8273 the test for 'install' more closely. Look at MKDIR_P first.
8274 Look in the PATH, and at /opt/sfw/bin.
8275 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8276 Don't bother to try mkdir -p, since we already check mkdir --version;
8277 just look at the version number. (There's no easy way to check
8278 for race-free implementations.)
8279 * tests/tools.at (autoconf: subdirectories): Adjust to above
8280 changes, since MKDIR_P now might end in "/mkdir -p".
8282 * doc/autoconf.texi (autoheader Invocation): Mention that the
8283 first arg of AC_DEFINE_UNQUOTED must be a literal.
8284 Problem reported by Ben Pfaff in
8285 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8287 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8288 * doc/autoconf.texi (Special Chars in Variables): New section.
8289 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8290 (Installation Directory Variables): Quote $(datadir) better.
8291 (Limitations of Builtins): Describe some of eval's trickiness.
8293 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8294 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8295 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8296 in front of every arg, not just trailing args. Quote apostrophes.
8297 (_AC_EVAL_ECHO): New macro.
8298 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8299 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8301 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8302 exposed by quoting of eval argument. Put the command on line line
8304 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8305 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8306 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8307 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8308 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8309 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8310 Use eval more safely.
8311 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8312 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8314 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8315 lines, exposed by quoting of eval argument.
8317 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8318 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8320 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8321 initialization of `ac_cv_exeext', do not override it if it was
8322 already set, unless it was set to `no', for compatibility with
8323 Autoconf-2.13, and comment this.
8324 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8325 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8326 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8327 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8328 Document that this test may be overridden by setting
8331 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8333 Revert these two patches:
8335 2006-04-06 Eric Blake <ebb9@byu.net>
8336 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8337 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8340 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8341 Clean up _AC_COMPILER_EXEEXT* macros.
8342 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8343 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8344 ac_file to the name of the default output file and call
8345 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8346 initial `rm' of the candidate files...
8347 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8348 the same list in subsequent `rm' calls, and for the temporary
8349 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8350 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8351 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8352 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8353 no longer needed) by libtool. Make it a cache check.
8354 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8355 copied here by mistake.
8356 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8357 _AC_COMPILER_EXEEXT.
8358 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8359 _AC_COMPILER_OBJEXT directly.
8360 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8362 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8364 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8365 Fix description of how the buggy `sed' works.
8367 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8371 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8372 ENOLCK. Only mention `make -j' when applicable. Only raise
8373 fatal errors when `make -j' is involved. Improve error message.
8375 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8377 * doc/autoconf.texi (Here-Documents): We now know more about
8378 the variable expansion in here documents bug.
8379 Thanks to Tim Rice and Stepan Kasal.
8381 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8382 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8384 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8386 * tests/autotest.at (Multiline command from M4 expansion):
8387 No failure to be expected if the shell quotes newlines in
8388 commands in the `set -x' output. Report by Tim Rice.
8391 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8393 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8394 expansion in the here-documents used by config.status, as that
8395 runs afoul of the Korn shell version M-12/28/93d bug described in
8396 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8397 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8398 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8400 2006-05-23 Jim Meyering <jim@meyering.net>
8402 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8403 Fix typo introduced with 2006-04-02 change. It reversed the sense
8406 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8408 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8409 ac_dB slightly, to save bytes in the script.
8410 Max out at 50 lines, rather than 96; this is more likely
8411 (though not guaranteed) to avoid obscure 'sed' failures.
8413 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8415 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8416 `tr -d -' as bad option argument. Work around this by deleting
8417 an unrelated character.
8418 Report by Tim Rice <tim@multitalents.net>.
8420 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8421 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8422 Stepan Kasal <kasal@ucw.cz>
8424 * doc/autoconf.texi (Particular Programs): Do not promise that
8425 we always prefer the GNU version of the program, and that we
8426 search according to PATH; both rules can have exceptions.
8427 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8428 AC_PROG_SED. Move descriptions of limitations
8429 to the Limitations of Usual Tools section.
8430 (Limitations of Usual Tools) <sed>: Mention script length
8431 limitations with Solaris /usr/ucb/sed.
8432 <grep>: Fix wording for empty alternative. Mention that -c and
8433 -l should not be combined, and that -E and -F should not be
8436 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8437 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8439 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8440 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8442 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8444 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8445 AC_DEFINE is now passed to m4_pattern_allow.
8446 * NEWS: Mention that; likewise for AC_SUBST.
8447 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8448 the parameter to m4_pattern_allow.
8449 * tests/tools.at: Add a check for that.
8451 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8453 * lib/autoconf/status.m4: Fix typos.
8455 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8457 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8458 only the files that this macro generates.
8460 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8462 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8463 the HP-UX sed limitation of 99 commands, labels do not count.
8464 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8466 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8468 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8470 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8471 Import the following fix from coreutils:
8473 2006-01-13 Jim Meyering <jim@meyering.net>
8475 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8476 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8477 not double-quote uses of that variable, to accommodate the rare
8478 case in which getmntent is available in none of the libraries
8479 checked. This happens at least on FreeBSD 5.0.
8481 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8483 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8484 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8485 some other programs unwisely rely on these undocumented vars.
8486 But put in warning comments about them.
8487 Problem reported by Ralf Wildenhues in
8488 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8489 * NEWS: Document that these variables are intended to go away.
8491 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8493 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8494 and set the language to C++ (analogous to the equivalent Fortran
8497 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8498 * doc/autoconf.texi (C++ Compiler): Document it.
8499 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8502 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8504 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8505 that caused config.status to generate 100-command sed scripts; the
8506 portable limit is 99.
8508 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8510 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8511 variable `ac_d' instead of `d' to avoid infringing namespace.
8512 Report by Ralf Menzel.
8514 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8516 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8517 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8518 * tests/tools.at (autoconf: subdirectories): New test, taken from
8519 the corresponding problem report by Ralf Wildenhues in:
8520 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8522 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8523 Quote some uses of shell variables if they might suffer unexpected
8524 globbing. This doesn't fix all instances of quoting problems that
8525 I found, just the easy ones that look safe.
8526 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8527 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8528 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8529 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8530 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8531 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8532 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8534 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8535 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8537 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8539 * bin/autoreconf.in ($help): Reword according to the manual.
8540 Suggested by Olly Betts.
8542 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8543 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8545 * bin/autoreconf.in: Pass the directory argument to
8546 `require_configure_ac'. Fix comment.
8547 * tests/torture.at (Configuring subdirectories): Expose this.
8548 Reported by Olly Betts.
8550 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8552 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8553 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8554 Automake as follows:
8556 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8557 `$configure_in' instead of `configure.in', to preserve
8558 directory component.
8560 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8562 * config/config.guess, config/config.sub, config/texinfo.tex,
8563 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8565 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8567 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8568 test for C99 conformance; (bool) 0.5 is an integer constant
8569 expression, but (bool) -0.5 is not. Problem reported by Fedor
8570 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8572 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8574 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8575 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8576 Warn about obsolete install-sh files. Remove stray sentence
8577 fragment and fix cross reference.
8578 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8579 install -d; this undoes the 2006-05-10 change.
8580 (MKDIR_P): Mark with AN_MAKEVAR.
8581 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8582 that we don't require $INSTALL to be thread-safe. Move comments
8583 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8584 of AC_PROG_INSTALL. Output a message saying that we're checking
8585 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8586 MKDIR_P instead of AC_SUBST.
8587 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8588 Special magic for MKDIR_P, too.
8589 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8591 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8593 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8595 Sync from Automake, as follows:
8597 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8598 * config/install-sh: Initialize IFS, so field splitting isn't
8600 * config/mkinstalldirs: Likewise.
8601 * config/missing: Remove superfluous quotes. Replace all uses of
8602 `[' by `test', for consistency, and for..
8603 * config/missing (sed_minuso, sed_output): New variables.
8604 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8605 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8606 Fixes `missing' to detect `--output' for help2man. Fixes
8607 PR automake/483. Report by Dennis J. Linse.
8608 (autom4te): Document in `missing --help'.
8610 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8612 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8613 * config/install-sh: Don't use 'path' to talk about file names,
8614 as per GNU coding standards. Close a race condition reported by Ralf
8615 Wildenhues and Stepan Kasal. There is still a race condition
8616 on hosts that predate Posix 1003.1-1992, but we can't help this.
8617 Don't mishandle weird characters like space on pre-Posix hosts.
8618 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8619 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8620 AC_PROG_MKDIR_P from AS_MKDIR_P.
8621 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8622 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8623 earlier editions are not (including Automake 1.8.3).
8624 Do not suggest mkinstalldirs for thread-safety.
8625 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8626 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8627 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8628 presence of special characters and race conditions.
8629 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8630 in Autoconf's name space.
8632 2006-05-10 Bruno Haible <bruno@clisp.org>
8633 and Paul Eggert <eggert@cs.ucla.edu>
8635 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8636 from Automake with minor changes.
8637 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8639 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8641 * config/install-sh: Update to Automake CVS version, as follows:
8642 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8643 * lib/install-sh: Simplify the expr implementation of dirname.
8644 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8645 * lib/install-sh: Handle --, and diagnose unknown options.
8647 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8649 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8650 `./autom4te' to create `./testsuite', since the `all' target
8651 will ensure its presence, but `installcheck' should not create
8652 the uninstalled wrappers.
8654 * tests/torture.at (Unusual Automake input files): Skip if we
8655 detect automake < 1.8.
8657 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8659 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8660 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8661 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8664 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8666 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8667 munge (multiple) white space and other oddities.
8668 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8669 single quotes in variable assignment.
8670 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8671 and similar failures by adding multiple spaces, tabs, and other
8673 Report and different test suggested by Francesco Romani
8674 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8676 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8677 single quotes, we only need to search for single quotes; this
8678 both simplifies the search pattern, and makes us less
8679 susceptible to `echo' variations for arguments not containing
8681 (_AC_ARG_VAR_VALIDATE): Likewise.
8683 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8685 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document

8769 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8771 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8772 since as_me isn't set yet.
8774 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8776 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8777 a few minor bugs in this area.
8779 * doc/autoconf.texi (Programming in M4sh): Comment out the
8780 documentation of AS_BASENAME, for now.
8781 (Shell Substitutions): Do not use AS_DIRNAME in an example.

8819 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8821 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8822 newline from the `trap' code to finish `config.log'; the NetBSD
8823 /bin/sh resets the exit status after an empty command, as
8824 documented in doc/autoconf.texi.
8825 Reported by Dalibor Topic <robilad@kaffe.org>.
8827 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8829 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8830 Suggested by Bruno Haible.
8832 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8834 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8835 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8836 Instead, just list the shells that we know work.
8837 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8838 changed. Be more cautious about the _cv_ variable.
8839 * tests/tools.at (Syntax of the shell scripts): Check the
8840 _cv_ variable once, at first, to avoid an internal autoconf error
8841 when sh -n does not work.
8843 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8845 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8847 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8849 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8850 use ">&-" since we're only 99.999% sure that this is portable,
8851 and since the MinGW bug is fixed in a different way.
8852 * lib/autotest/general.m4 (AT_INIT): Likewise.
8854 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8856 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8857 before opening config.log, to avoid hitting a bug on MinGW.
8859 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8861 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8862 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8863 This works around a MinGW bug reported by Eric Paire.
8864 Make sure that all writes to the log file append to it,
8865 rather than possibly losing data.
8866 * lib/autotest/general.m4 (AT_INIT): Likewise.
8868 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8870 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8873 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8877 * configure.ac (AC_INIT): Bump to 2.59d.
8879 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8883 * Makefile.maint (news-date-check): Do not require a leading `*'
8884 before the release date in NEWS.
8886 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8887 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8889 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8890 the instantiated file do not contain the string 'datarootdir'
8891 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8892 @mandir@, replace the reference '${datarootdir}' by the value.
8893 * tests/torture.at (datarootdir workaround): New test.
8894 * NEWS: Advertise this temporary fixup.
8895 Based on a patch by Bruno Haible, reported and analyzed by
8896 Paul Eggert and Noah Misch.
8898 2006-04-12 Eric Blake <ebb9@byu.net>
8900 * tests/autotest.at (Debugging a failed test): Fix comment.
8902 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8904 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8905 all the changes since 2006-04-07.
8907 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8909 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8910 succeeded, but `ln -s file dir' failed, take care to remove the
8911 leftover target before the next test, to prevent its spurious
8912 failure; also make sure `ln file dir' works before selecting it.
8913 Thanks to Keith Marshall for pointing this out.
8916 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8917 assignments in `at_debug_args', so that we put them correctly
8918 in the `run' script.
8919 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8920 Reported by Eric Blake.
8922 2006-04-11 Eric Blake <ebb9@byu.net>
8924 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8925 top-level tests after micro-suite has been run. Used in...
8926 (Debugging a successful test, Debugging script and environment),
8927 (Debugging a failed test): ...these new tests. The first of these
8929 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8930 macro, split out from...
8931 (AT_INIT): ...here, so that using -d also generates a run script.
8932 Document that -d inhibits top-level logging.
8933 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8934 inhibits top-level logging; debug scripts are created.
8936 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8938 * tests/autotest.at (Empty test, Empty check): New test to check it.
8940 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8943 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8945 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8946 the files if a problem appears. Make the empty *.at files
8947 read-only, too. Proposed by Ralf Wildenhues.
8949 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8951 * config/Makefile.am: Add comment to force updated Makefile.in.
8953 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8954 space only patch to this file, this patch causes the Makefile.in
8955 files that include freeze.mk to be updated, and thus have a
8956 newer time stamp again, which in turn makes a pristine CVS
8957 checkout have correct time stamps.
8959 * Makefile.maint (cvs-sv): New macro, to be used..
8960 (config.guess-url_prefix, config.sub-url_prefix)
8961 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8962 point to CVS text checkout of Gnulib files.
8963 (copyright-check): Bump current year.
8964 (announcement): Do not hard-wire `./announce-gen'.
8965 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8967 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8969 (wget_files): Update config.guess, config.sub, texinfo.tex by
8970 `wget-update', now that their URLs work again.
8972 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8974 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8975 Problem noted by Paul D. Smith.
8977 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8979 * doc/autoconf.texi: Remove unused words from word list.
8980 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8981 .x-sc_trailing_space: New files.
8983 * doc/standards.texi: Sync from gnulib.
8985 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8986 `LIBOBJDIR' as experimental.
8988 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8989 with a target directory; it's internally implemented as `cp'
8990 anyway, but since Autoconf advertises the possibility to use
8991 a target directory when LN_S is `ln -s', we need to find out.
8992 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8993 analyzed by Keith Marshall <keith.marshall@total.com>.
8997 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8999 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9000 confdefs.h as-is. In general, if it has backslash-newline or the
9001 like, then it doesn't work either to sort or to remove empty
9004 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9006 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9008 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9010 * lib/autom4te.in (Automake-preselections): Preselect
9013 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9015 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9016 apostrophe within a single-quoted string, as this is the usual
9017 tradition and is easier to read than '"'"'. Don't rely on the
9018 shell treating "$/" like '$/'. Use a more-consistent indenting
9021 2006-04-09 Eric Blake <ebb9@byu.net>
9023 * tests/autotest.at (Backquote command substitution),
9024 (Multiline backquote command substitution): Remove mistaken
9025 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9027 (Parenthetical command substitution, Multiline parenthetical
9028 command substitution): here.
9030 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9032 Import macros from gnulib (often changing their name).

9063 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9064 (C Compiler): Move AC_C_LONG_DOUBLE to ...
9065 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
9066 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
9067 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
9068 (Coding Style). Don't mention m4_expand_once.

9105 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9107 Revert the patch from 2006-04-01 and only improve
9108 _AS_DETECT_BETTER_SHELL:
9110 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9111 skip nonexistent directories.

9161 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9163 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9164 whether `set' quotes correctly: redirect stderr of the tested
9165 `set', and use a subshell, for Ultrix; use `sed' instead of
9166 `grep' for zsh `set' which may write binary output; match only
9167 at the beginning of a line, to avoid false positives.
9168 In order to avoid false positives by unrelated variables with
9169 multiline content, put the dump algorithm in a subshell and
9170 unset all variables containing newlines (except some which are
9171 special to the shell). Warn about cache variables that are

9176 * config/config.guess, config/config.sub, config/texinfo.tex:
9179 * tests/mktests.sh: Reword comments.

9184 (AC_ARG_VAR): Do test this now.
9185 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
9186 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).

9217 ac_config_<foo>s again, sometimes normalized, sometimes not.
9218 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9219 (AC_CONFIG_COMMANDS): Do not do so here.
9220 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9221 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

9232 for --help from Cygnus `configure.'
9234 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

9282 Use simplified args that Eric Blake originally suggested.
9284 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
9286 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
9287 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
9288 Use 'comm' rather than N instances of grep; this also fixes a bug
9289 whereby substrings were incorrectly matched, causing us to not
9290 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
9291 (exclude_list): Exclude empty macros.
9292 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
9294 Use awk rather than grep -E or egrep, to avoid

9377 ac_file to the name of the default output file and call
9378 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9379 initial `rm' of the candidate files...
9380 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9381 the same list in subsequent `rm' calls, and for the temporary

10101 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10102 ac_clean_files and LIBOBJS.
10104 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10106 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
10107 Factor functionality to..
10108 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
10109 `AC_SUBST($1)' in the public version.
10110 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
10111 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
10114 2005-11-01 Stepan Kasal <kasal@ucw.cz>
10116 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
10119 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10121 * NEWS: Move AH_HEADER mention to right place.
10123 2005-10-27 Stepan Kasal <kasal@ucw.cz>
10125 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
10126 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
10128 2005-10-25 Stepan Kasal <kasal@ucw.cz>
10130 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
10131 conftst2.$ac_objext.
10132 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
10134 2005-10-24 Stepan Kasal <kasal@ucw.cz>
10136 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
10137 conftest.o, to see whether the compiler really obeys; rm the object
10138 file before and after the test and register it with ac_clean_files.
10139 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
10141 2005-10-21 Stepan Kasal <kasal@ucw.cz>
10143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
10144 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
10145 code so that the most common case requires less forks.
10147 2005-10-20 Stepan Kasal <kasal@ucw.cz>
10149 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
10150 not portable; thanks to Paul Eggert and Alexandre.
10152 * NEWS: Fix an old typo.
10154 2005-10-20 Jim Meyering <jim@meyering.net>
10156 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
10157 the latter'', in two places.
10159 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
10161 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
10162 AC_LANG_PROGRAM, fixing a typo. Don't give details about
10163 the inner workings of AC_LANG_FUNC_LINK_TRY.
10164 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
10165 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
10166 by the function rather than ignoring it.
10167 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
10168 comparing its address. Intel's interprocedural optimization was
10169 outsmarting the old heuristic. Problem reported by
10172 2005-10-19 Stepan Kasal <kasal@ucw.cz>
10174 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

10181 2005-10-04 Stepan Kasal <kasal@ucw.cz>
10183 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
10184 before removing it (chmod -R u+rwx); there are three instances of this.
10186 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10187 Stepan Kasal <kasal@ucw.cz>
10189 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
10190 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
10191 make its content writable before removing it. Remove an errorneous
10192 comment from the end, where the logs of the failed tests are copied
10193 to the main log file.
10195 2005-09-27 Stepan Kasal <kasal@ucw.cz>
10197 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
10198 in case the computer is too quick. Double quote the configure.ac
10201 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
10202 problems if the testsuite were running too fast.
10204 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10206 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10207 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10208 (which belong to Xt, not X itself). See Debian bug 327655.
10209 * NEWS: Mention this.
10211 2005-09-07 Stepan Kasal <kasal@ucw.cz>
10213 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
10215 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
10217 * config/move-if-change: Don't output "$2 is unchanged";
10218 suggested by Ben Elliston. Handle weird characters correctly.
10220 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10222 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10223 calls, so that the final expansion of this macro is shorter.
10224 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10225 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10226 the cleanup there. Use AS_VAR_* macros, to be more general.
10227 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10229 * lib/autoconf/general.m4: Use AS_IF where appropriate.
10231 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
10233 2005-09-01 Stepan Kasal <kasal@ucw.cz>
10235 * doc/autoconf.texi (Configuration Headers): Add an index entry
10238 2005-08-26 Pavel Roskin <proski@gnu.org>
10240 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
10241 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
10244 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10246 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10247 The previous patch didn't work, so try a better one.
10249 2005-08-26 Stepan Kasal <kasal@ucw.cz>
10251 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
10252 in the example. Reported by Bruno Haible.
10253 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
10254 "if $undefined_var;" succeeds with my shell.
10256 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10257 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
10258 but change the m4_divert_text to m4_divert_once.
10260 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10262 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10263 Work around bug in Solaris /usr/xpg4/bin/awk.
10264 The bug is present in at least Solaris 8 through 10.
10266 2005-08-24 Stepan Kasal <kasal@ucw.cz>
10268 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
10269 some evil values and relying on the fact that $* concatenates the
10270 parameters by the first character from IFS.
10272 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10273 Stepan Kasal <kasal@ucw.cz>
10275 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10276 first header appears, define AH_HEADER.
10277 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10278 Update limitations about when to call AC_CONFIG_HEADERS.
10279 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10280 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10281 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10282 ``Configuration Actions''; fix their index entries.
10284 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10285 options correctly. Process N-M as M-N if M is smaller than N.
10286 Process ranges correctly so that N-N will run only N.
10287 Sort and uniquify the tests that will be run. If there is more
10288 than one test, reinsert the banners for the tests.
10289 * tests/autotest.at (Keywords): Unmark XFAIL.
10291 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10293 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10294 before passing the macro name to AH_TEMPLATE.
10296 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10297 now opens log after option processing; in particular, --version
10298 and --help do not touch config.log.
10300 * Makefile.maint: Revert the change from 2005-08-12.
10302 2005-08-22 Stepan Kasal <kasal@ucw.cz>
10304 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
10306 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

10310 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
10311 (Autotest Logs, Writing testsuite.at, testsuite Invocation):

10315 Prepend to LIBS, not append, in examples.
10317 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10319 When building in place, set srcdir="."; suggested by Tim Van Holder.
10321 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10322 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10323 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10324 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10325 does not mean "no --srcdir option".
10327 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10329 * tests/autoscan.at (autoscan): New file.
10330 * tests/suite.at: Use it.
10331 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10332 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10334 * tests/autotest.at (Keywords): Test keywords combinations.
10336 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10338 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10339 add "2>&1"; gzip 1.2.4 prints help on stderr.
10341 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10343 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10344 was pushdef'ed twice while popped only once. Push it only once.
10345 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10347 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10349 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

10354 * Makefile.maint: Update from Bison.
10356 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10357 "<tab>" in comment, so that the point is understandable.
10359 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10361 Rewrite substantial part of lib/autoconf/status.m4.
10362 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10363 and CONFIG_COMMANDS are not processed in four separate loops.
10364 Instead, there is one main loop. This alows that the common code
10365 is expanded only once, thus config.status (and configure) is smaller.
10367 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10368 the AC_LIST_FILES and cousins macros are no longer used.
10370 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10371 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10372 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10373 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10374 contain the initialization, nor the for loop, nor the associated
10375 commands; all these go to ...
10376 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10377 _AC_OUTPUT_CONFIG_STATUS.
10378 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10379 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10380 (_AC_OUTPUT_FILE): The creation of the sed script ...
10381 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10382 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10383 _AC_OUTPUT_MAIN_LOOP.
10384 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10385 _AC_CONFIG_COMMANDS): Use ...
10386 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10387 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10388 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10389 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10390 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10391 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10393 (_AC_CONFIG_UNIQUE): Update.
10394 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10395 Replaced by this ...
10396 (_AC_LIST_TAGS): ... new common macro.
10397 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10398 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10399 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10400 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10401 this didn't belong to the `config commands' section.
10402 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10403 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10404 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10405 to the `config commands' section either.
10406 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10407 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10409 ... and many changes to the comments nearby.
10411 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10412 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10413 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10414 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10415 (#define header templates): The comment at the top of the generated
10416 header now includes the name(s) of the source file(s).
10418 Several unrelated small changes:
10420 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10421 parameter to AC_DIAGNOSE.
10422 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10423 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10424 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10425 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10426 with AU::AC_OUTPUT.
10427 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10428 in AC_OUTPUT doesn't double-quote it either.
10429 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10432 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10434 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10435 versions of Portland Group compiler produce single- and double-quoted
10436 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10437 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10439 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10441 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10442 This is a corrected version of yesterday's patch.
10444 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10446 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10447 path, too; insert a "===" to emphasize the line.
10449 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10450 ac_cv_build_alias to ac_build_alias.
10451 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10453 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10454 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10455 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10456 (AC_ARG_VAR): ... here.
10457 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10460 Keep a list of all precious variables and process them with one simple
10461 for loop, instead of expanding all commands, or, OTOH, complicated
10462 processing of output of "set".
10463 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10464 variable names in new macro...
10465 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10466 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10467 a loop to assign all ac_env_* and ac_cv_env_* variables.
10468 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10470 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10471 its value to shell variable ac_precious_vars and call
10472 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10473 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10474 _AC_ARG_VAR_VALIDATE.
10476 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10477 and the AC_SUBSTs ...

10481 the ac_subst_files section in config.log.

10494 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10495 They are generated by the Tru64 v5.1B shell.
10497 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10499 Fix my changes from 2005-07-01; reported by Noah Misch.
10500 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10501 description, the macro now accepts only a single tag.
10502 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10504 Fix cases when the varsions of Autoconf and Autotest don't match.
10505 Reported by Noah Misch.
10506 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10507 at_top_builddir, for compatibility with older autotest.
10508 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10509 is not set, use at_top_builddir, for compatibility with older
10510 versions of autoconf.
10512 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
10514 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10515 Problem reported by Patrick Welche.
10517 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10519 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10520 sed substitution command, so that we allow | in program prefixes
10521 and program suffixes. (& is a problem anyway; we're not fixing
10523 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
10524 configure_input, top_builddir, srcdir, etc.
10525 * lib/autotest/general.m4 (AT_INIT): Likewise, for
10526 PATH_SEPARATOR in AUTOTEST_PATH.
10528 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
10530 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10531 for loop over config.site files using `set', to allow
10532 directory names containing IFS characters.
10534 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10536 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10537 directories with weird names. Apparently some people like living
10538 on the edge. However, improve the test that "pwd" actually does
10539 report a name for the working directory.
10540 * NEWS: Remove the claim that we test for funny chars in dir names.
10542 2005-07-01 Stepan Kasal <kasal@ucw.cz>

10558 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10559 document to output the default config_* lists to config.status.
10560 Don't recognize option --file, if the functionality is not there.
10561 Likewise for --header; moreover, recognize --he and --h as shortcuts
10562 for --help in that case.
10564 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10565 matches the order of execution. No code changed.

10587 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10588 (AC_SUBST): Call it.
10589 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10590 the directory specific variables; but don't call it for configure_input.
10592 2005-06-28 Derek Price <derek@ximbiot.com>
10594 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10597 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10599 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10600 directory have inherent problems with special characters like spaces,
10601 due to limitations in Make syntax. Problem reported by Alexandre
10603 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10604 Also, fix Tru64 porting problem with shell patterns,

10616 from Justace Clutter.
10617 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10618 variable into diagnostic. Make the diagnostic an error, not a warning,
10619 because we really don't support spaces and suchlike in dir names.
10620 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10621 Don't worry about backslashes in srcdir; it can't happen now.

10634 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10635 that '\|' is not allowed in BREs; recommend using newline separated
10636 list of patterns instead of multiple -e options.

10646 2005-06-21 Stepan Kasal <kasal@ucw.cz>
10648 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
10649 b, t, r, w commands require single space, while : cannot have any.
10650 (Special Shell Variables): Fix sed code this in the example.
10651 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10652 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10654 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10655 expand to the empty list. Don't use two pairs of m4_changequote,
10656 it's not necessary.
10658 2005-06-20 Derek Price <derek@ximbiot.com>
10660 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10662 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10664 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10665 * doc/autoconf.texi:
10666 Don't mention Solaris versions so much, if a
10667 problem is common to all extant versions of Solaris. Say "SunOS
10668 4" instead of "SunOS" for SunOS 4.
10669 (awk): Mention more of the limitations of traditional Awk.
10670 (cat): Don't talk about cat -v.
10672 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
10674 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
10675 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

10678 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10680 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

10683 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10684 Use shell builtins rather than 'expr', to work around expr bug.
10686 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10688 * doc/autoconf.texi: "filesystem" -> "file system".
10689 "behaviour" -> "behavior".

10691 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10693 * lib/m4sugar/m4sh.m4: Likewise.
10694 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
10695 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

10698 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10699 to update the man page. That way, we don't have to check in new
10700 man pages every month.
10702 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10703 quotes and backslashes. Patch from Derek Price.

10713 -u, since it outputs chatter if the input files are the same.
10714 Problem reported by Ralf Menzel.
10716 2005-06-08 Derek Price <derek@ximbiot.com>
10718 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10719 renaming them since they are about to be redefined anyhow.
10721 2005-06-08 Derek Price <derek@ximbiot.com>
10723 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10724 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10725 Move m4_undefine to alphabetical order.
10727 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10729 * README: Recommend GNU M4 1.4.3 or later.
10730 * doc/autoconf.texi (Introduction): Likewise.
10731 Reword to avoid some formatting glitches.
10732 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10733 Clarify explanation of HP compiler bug.
10734 Redo example output tp match current CVS snapshot.
10735 Use @example.org in email addresses when the examples
10736 might get inadvertently cut-and-pasted into user code.
10737 Remove example of autom4te usage that doesn't seem to work now.
10738 Use modern AC_INIT (except when the example is meant to be
10739 shown with Autoconf 2.13).
10740 Update ksh info for Solaris 9 and later.
10742 Modernize description of Automake versions a bit.
10743 Don't claim a future version of Autoconf is near.
10744 * doc/install.texi: Reword to avoid some formatting glitches.
10746 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10748 * doc/autoconf.texi: Add [] to examples, so that the manual
10749 follows its own advice about quoting better.
10750 Reword to avoid some formatting glitches.
10751 * doc/installt.exi: Reword to avoid some formatting glitches.
10753 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10754 Tru64 ksh pattern matching bug. Reported against Libtool by
10755 Albert Chin <libtool@mlists.thewrittenword.com> and
10756 Nicolas Joly <njoly@pasteur.fr>.
10758 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10760 m4_cdr of one-member list was [[]] (one-member list containing an
10761 empty string) instead of [] (an empty list. Callers were skewed to
10762 match this misbehaviour. As a consequence of this:
10763 - m4_foreach([x], [], [foo]) expanded to `foo', while
10764 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10765 This bug has been fixed:
10767 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10768 expand to an empty string; print error msg if called without
10770 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10771 misbehaviour; handle [] and [[]] correctly.
10773 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10775 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10776 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10777 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10779 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10781 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10782 swallow records with more than 99 fields.
10783 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10784 parse the long line.
10786 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10788 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10789 swallow literals longer than 399. Reported by Ralf Wildenhues.
10790 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10791 to workaround this limitation.
10793 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
10795 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
10796 to gfortran, and make these the first two compiler names

10801 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

10805 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
10807 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10808 expression of unbounded size when processing the --list
10809 option. This runs afoul of a limit of 399 bytes per regular
10810 expression on AIX. Problem reported by Ralf Wildenhues.
10812 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

10815 * doc/autoconf.texi (Particular Headers): Reword example
10816 for multiline stdbool replacement.
10817 (Setting Output Variables): Reword text a bit. Don't
10818 give all the details about |#_!!_#|.
10819 Reword description of line replacement.
10821 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10823 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10824 now contain newlines, and substituted files must be referenced on
10825 a line alone; the sed scripts to substitute them are now very
10827 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10828 commands can be put in a sed script portably.
10829 * doc/autoconf.texi (Setting Output Variables): Document above
10830 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
10831 use of multiline substitution.

10837 From Ralf Menzel (trivial change).
10839 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10841 * tests/local.at: Don't attempt to check for negated character
10842 classes in shell scripts. The test was too brittle.
10844 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10846 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

10850 2005-05-24 Stepan Kasal <kasal@ucw.cz>
10852 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

10857 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
10859 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
10860 messages when ac_unique_file is not found.
10861 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10862 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10863 commands, for consistency with AC_MSG_ERROR and such.

10878 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
10879 (ac_top_builddir): ... this ...
10880 (ac_top_build_prefix): ... to this; the old name is also kept, for
10881 backward compatibility.
10882 (ac_top_builddir_sub): New variable, without the trailing slash,
10884 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
10885 * doc/autoconf.texi (Configuration Actions): Rename
10886 ac_top_builddir to ac_top_build_prefix.

10898 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10899 argument to m4_foreach. I guess it was necessary in the past,
10900 but I think it's a no-op now.
10902 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10904 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10905 ``cat <<_ACEOF'' commands to one.
10906 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10907 * lib/autoconf/status.m4: On various places, use expr instead of

10913 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10914 the wrong patterns between ``case'' and ``esac.'' The previous
10915 code had false positives.

10981 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10983 * doc/autoconf.texi (Autoconf Language): Be more precise about
10984 quoting rules. Problems noted by Stepan Kasal.
10985 Also, throughout this document, be more careful about white space.
10986 "blank", "white space", and "space" all have different meanings
10987 and we should be careful to say what we mean.

11023 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
11026 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11027 by AC_DEFINE; it was a mistake.
11028 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
11030 2005-04-25 Stepan Kasal <kasal@ucw.cz>

11034 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11036 * doc/autoconf.texi (External Software): Quadrigraphs are not
11037 processed correctly in AS_HELP_STRING; avoid this in the examples.
11038 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11039 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11040 comment and reduce m4_default([foo], []) to [foo].
11041 (m4_strip): Update the explanation.
11043 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11045 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11046 Remove core.conftest.* too; it's generated by Tru64 5.1.
11047 Problem reported by Jennis Pruett.
11048 * lib/autoconf/functions.m4
11049 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

11097 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11098 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11099 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11100 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11101 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

11105 * NEWS: The configure command now warns you if you attempt to use
11106 a directory whose name contains a special character like space,
11108 * doc/autoconf.texi (Installation Directory Variables): Allow
11109 "," in file names. Do not use \@; it's not a portable regexp.

11122 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
11123 ac_pwd, and quote srcdir.
11124 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11126 * doc/autoconf.texi: Fix some systematic formatting problems.
11127 ".)" needs a following @: if not at the end of a sentence, and
11128 similarly for "!)". "etc." should be preceded by a comma.
11129 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11131 2005-03-22 Bruno Haible <bruno@clisp.org>
11133 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
11134 argument is often called 'build-aux'.
11136 2005-03-07 Stepan Kasal <kasal@ucw.cz>
11138 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
11139 macro AC_TRY_LINK is obsolete.
11140 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
11143 2005-02-24 Stepan Kasal <kasal@ucw.cz>
11145 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11146 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11147 from a Common Lisp's `cl'.
11148 (AC_PROG_CXX): Behave according to the documentation: don't
11149 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11150 make the variable CCC precious; use `cl.exe', not `cl'.
11152 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11153 Alexandre Duret-Lutz <adl@gnu.org>
11155 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11156 /dev/null, as "configure" shouldn't read stdin, and this insulates
11157 us from problems (e.g., when testing for "cl"). Also, do this
11158 redirection before invoking "hostname" or "uname", and keep the
11159 original input stream available via...
11160 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11161 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

11171 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11173 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11174 newline if neither \c nor -n work, as that would output two
11175 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11177 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11179 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
11180 This causes that any required macros inside will get before the if.
11181 * doc/autoconf.texi (autom4te.cache): A typo.
11183 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11185 Undo previous change, except keep the change to
11186 lib/autoconf/programs.m4 that replaced grep with shell
11187 pattern-matching. This is because net-snmp configure reads stdin.
11188 Reported by Noah Misch.
11190 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
11192 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11193 from /dev/null, as "configure" shouldn't read stdin, and this
11194 insulates us from problems (e.g., when testing for "cl").
11195 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11196 before invoking "hostname" or "uname".
11197 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11198 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11199 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11200 "</dev/null" since it's now done at the top of 'configure'.
11201 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11202 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11203 Also, replace grep with shell pattern-matching, to save a process.
11205 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
11207 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11208 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11209 avoid thinking that Allegro Common Lisp's "cl" command is a C++
11212 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
11214 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11215 grep -q isn't portable. Improve grep -s explanation.
11216 Problem reported by Dan Manthey.
11218 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
11220 * doc/autoconf.texi (Special Shell Variables): Clarify
11221 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
11223 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11225 * doc/autoconf.texi: Use @acronym for DJGPP.
11226 Fix some @code's that should have been @env's, and vice versa.
11227 Sort environment variable names.
11228 Mention that shells no longer inherit IFS.
11229 Don't recommend PATH_SEPARATOR=';' so strongly.
11230 Mention that $RANDOM might expand to the empty string.
11231 "symlink" and "soft link" -> "symbolic link".
11232 Improve mktemp description (reported by Bruno Haible).

11270 CPPFLAGS to `configure' instead of setting it in `configure'.
11272 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
11273 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

11308 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

11371 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11372 Update the long comment explaining it.
11374 m4_require no longer writes an ``is required by'' line to the
11375 execution stack. It contains only one bit of non-redundant
11376 information: that the macro was required, not called. And even
11377 this bit is useless in most situations: have you ever met a macro
11378 which both calls and requires the same macro?
11380 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11381 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11384 (m4_expansion_stack_pop): Remove the misplaced comment.
11385 (m4_require): Don't put the ``is required by'' line to the
11386 execution stack; slightly improve the out-of-a-defun error message.
11387 (_m4_divert_grow): New macro, counter for the temporary diversions.
11388 (_m4_require_call): Use it.
11389 * tests/m4sugar.at (m4_require): Expect output without the
11390 ``is required by'' messages.

11800 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11801 "char c = '\200';" rather than "char c = 0x80;" as the

11866 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
11867 the $1_found variable, don't test whether the file is executable;
11868 Both things are checked ...
11869 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
11870 the former ``test -f''.
11871 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
11873 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

11880 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
11881 limitations. Reorder paragraphs for clarity.
11883 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
11885 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
11886 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
11887 variants", "Unix", and some related minor wording fixups.
11889 (Shellology, Special Shell Variables): Document that the Zsh
11890 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

11904 * doc/autoconf.texi (auindex): New macro.
11905 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
11906 Problem reported by Stepan Kasal.
11908 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
11910 Fix problems reported by Andreas Buening in:

11912 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11914 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
11915 readable; it's not true in OS/2-emx.
11917 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
11919 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11920 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11921 (trivial change). Problem and patch reported by Andrew Church in:
11922 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
11924 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
11926 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

11929 Also, fix some minor spacing and punctuation bugs.
11931 2004-09-02 Akim Demaille <akim@epita.fr>
11933 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
11934 "case" to restore ordering.
11935 Reported by Stepan Kasal.
11937 2004-08-26 Akim Demaille <akim@epita.fr>

11952 texinfo.tex for now (done by hand now).
11953 * Makefile.maint (wget_files, cvs_files):
11954 Remove ansi2knr.c; nobody uses it.
11955 (ansi2knr.c-url_prefix): Remove.
11956 (cvs-update): Fix test for failure. I don't know why it ever
11959 * doc/autoconf.texi: Update URLs, some of which went stale.
11960 Use @uref rather than @href.
11962 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
11963 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
11965 * config/config.guess, config/config.sub, config/elisp-comp,
11966 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
11967 doc/fdl.texi, doc/standards.texi: Sync with master copy.
11969 * NEWS, TODO, configure.ac, bin/autoscan.in,
11970 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
11971 doc/install.texi, lib/Autom4te/Configure_ac.pm,

11976 tests/tools.at, tests/torture.at:
11977 Use "file name" rather than "filename" or "path",
11978 to be consistent with the terminology of the GNU coding standards.
11980 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
11982 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
11983 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
11984 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
11985 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
11987 More fixes to support spaces in the name of the build directory.
11988 This isn't a complete fix but it's an improvement.
11990 * bin/autoconf.as (autom4te_options): New var.
11991 Use it instead of appending to AUTOM4TE, so that we can allow
11992 spaces in the build directory's absolute name.
11993 * bin/autoheader.in ($autoconf): Allow spaces in file names.
11994 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
11995 AT_CHECK_NOESCAPE): Likewise.
11996 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
11997 main program): Likewise.
11999 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
12001 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

12005 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
12007 * doc/autoconf.texi (Function Portability): Document isinf and
12008 and isnan. From a suggestion by Kevin Ryde.
12010 * lib/Autom4te/General.pm (END): Return correct exit status even
12011 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
12013 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
12015 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
12016 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
12017 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
12019 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
12021 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
12022 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
12023 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
12024 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
12025 * lib/autom4te.in (Automake-preselections): Preselect
12026 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
12028 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12030 * lib/autom4te.in (Automake-preselections): Preselect
12031 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12034 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12036 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12038 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12039 Document problem with "`""`" in pdksh POSIX mode.
12041 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12043 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12044 with pdksh, too. Problem reported by Patrick Welche via
12046 * doc/autoconf.texi (Shellology): Note that set -o posix is
12047 useful for pkdsh, too.
12049 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12051 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12052 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12053 Don't fail if ENV or BASH_ENV is readonly.
12054 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12055 etc. are read only. Problem reported by Ludovic Courtes.
12057 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12059 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12060 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12063 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12065 * doc/autoconf.texi (File System Conventions): Warn about
12066 names like "aux". Problem reported by Eric Blake.
12068 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12069 by zero instead of array size, so that we can use any arithmetic
12070 constant expression (instead of requiring an integer constant
12071 expression). This allows us to test expressions like DBL_MAX <
12072 LDBL_MAX, which didn't conform to the C standard using the old
12074 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12075 now that we can do floating-point tests at compile time.
12077 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12079 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12080 and LDBL_EPSILON, as the resulting expression isn't an
12081 integer constant expression and violates the C standard.
12082 Problem reported by Nelson H. F. Beebe. Also, check
12083 for "L" suffix, and check that long double doesn't have
12084 worse range or precision than double, that mixed-mode
12085 arithmetic doesn't generate a diagnostic, that double
12086 constants fit in long double.
12088 2004-06-03 Kevin Ryde <user42@zip.com.au>
12090 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12091 malloc(0) and realloc(NULL,size).
12093 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12096 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12098 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12099 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12102 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12104 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12105 can be rewritten using if-then-else. Suggested by Bruno Haible.
12107 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12109 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12110 Problem reported by Stepan Kasal.
12112 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12114 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12115 change). Patch reported by Ralf Wildenhues in
12116 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12118 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12119 function F exists if the compiler and linker let you compile an
12120 expression like (F != 0). Recent versions of GCC optimize away
12121 the reference to F in that case, since every function address must
12122 be nonzero, so the link succeeds even if F does not exist.
12123 Problem reported by Manu in
12124 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12126 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12127 "Unix". Many uses changed.
12128 (Limitations of Builtins): Explain better why the ! command isn't
12131 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12133 * lib/autom4te.in (Automake-preselections): Preselect
12134 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
12136 2004-05-19 Kevin Ryde <user42@zip.com.au>
12138 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12139 referencing AC_FUNC_STRERROR_R.
12141 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12142 note pessimistic assumption when cross compiling.
12144 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12146 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12147 (until 2004) invoked subcommands with sh -e, contra POSIX.
12148 Reported by Kevin Ryde.
12150 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12152 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12153 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12154 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12155 `test -f " /usr/bin/grep"', which _always_ failed.
12156 (AC_PROG_SED): Ditto bogus PATH fix.
12157 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12158 requires that grep correctly supports _multiple_ `-e' options, rather
12159 than stating only that grep should accept `-e'.
12161 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12163 Port to C99, which requires that 'exit' be declared.
12165 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12166 to ensure that stdlib.h is included.
12167 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12168 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12169 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12170 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12171 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12172 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12173 when using 'exit' in a test; C99 requires that 'exit' be declared.
12175 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12177 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12178 now prefers 'grep' implementations that accept -e.
12179 (Limitations of Usual Tools): Describe problems of traditional
12180 egrep and fgrep with long input lines, and of traditional grep
12182 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12183 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12184 All callers changed. Append /usr/xpg4/bin to the PATH, for
12186 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12187 the user with complaints about multiple -e options.
12188 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12189 Define it with AC_PROG_GREP.
12190 * configure.ac (AC_PROG_GREP): Add.
12191 * lib/freeze.mk (GREP): New macro.
12193 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12195 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12196 a possible candidate only after all others fail, rather than
12197 consulting it first. This improves backward compatibility by
12198 better reflecting the way shell selection occurred in previous
12199 versions of Autoconf, and should help to avoid triggering latent
12200 problems in other packages, such as the one in Automake where zsh
12201 is not handled robustly:
12202 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12203 Although it is not Autoconf's responsibility to work around
12204 problems in Automake, it nevertheless makes sense to avoid
12205 introducing unnecessary incompatibilites.
12207 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12208 Gary V. Vaughan <gary@gnu.org>
12210 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12211 how deeply nested we are when a suitable tool is found, set the
12212 ac_path_TOOL_found flag.
12213 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12214 nested we are in this macro. Break out of all 3 nested loops if
12215 ac_path_TOOL_found is set.
12217 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12219 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12220 of the _AS_PATH_WALK loop too if GNU flavor is found.
12222 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12224 * doc/autoconf.texi (Limitations of Make): Update documentation
12225 for `$<'. New entry `Long lines', based on a report from Simon
12226 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12227 paragraph about DJGPP, based on a mail from Richard Dawe.
12229 2004-04-20 Paul Eggert <eggert@twinsun.com>
12231 * tests/c.at (C keywords): Don't assume that GCC supports
12232 "restrict" and "inline", as sufficiently-old GCC versions do not
12233 (also, GCC configured to be in pedantic C89 mode does not).
12234 Problem reported by Sumit Pandya in:
12235 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12237 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12238 consider -g to work if it generates warnings when plain compiles
12239 don't. Problem reported by Braden McDaniel in:
12240 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12242 * doc/autoconf.texi (Slashes): New section, to document a problem
12243 reported by Jim Meyering in:
12244 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12246 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12247 linker output files before linking, to work around IRIX 6 linker bug.
12248 Problem reported by Rainer Orth in:
12249 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
12251 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12253 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12254 best tool so far counter rely on the tool path variable name to
12255 avoid checks for one tool being affected by the results of running
12256 the length check on a previous tool.
12258 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12259 match expression argument, as different greps have different
12260 regular expression flavours.
12261 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12263 (AC_PROG_EGREP): Pass 'EGREP$'.
12264 (AC_PROG_GREP): Pass 'GREP$'.
12266 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12268 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12269 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12271 2004-03-29 Paul Eggert <eggert@twinsun.com>
12273 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12274 Types, Specific Compiler Characteristics, System Services,
12275 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12276 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12277 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
12278 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
12280 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
12281 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,

12289 2004-03-28 Paul Eggert <eggert@twinsun.com>
12291 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12292 now defines HAVE_DECL_TZNAME if it is declared, when
12293 HAVE_STRUCT_TM_TM_ZONE is not defined.
12294 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12295 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
12298 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
12300 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
12301 superfluous backslashing of quotes (") in sed expressions;

12387 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

12396 AC_SUBST provides no portable way to escape literal newlines.
12398 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12399 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12400 Darwin uses -lcrt2.o and there's little point to cataloging all
12401 the system variants. Partial fix reported by Andreas Waechter in:

12427 Paul Eggert <eggert@twinsun.com>
12429 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12430 (AS_INIT): Output shell initialization there. Removed optional
12431 parameter. Expand _AS_SHELL_FN_SPY.

12446 use AS_INIT_WITH_SHELL_FN.

12477 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

12479 the 2003-05-22 change, which removed the older years from the list.
12480 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

12493 _AC_PROG_GREP, and AC_PROG_SED.
12494 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12495 longest input length accepted by a command.

12524 2004-01-26 Paul Eggert <eggert@twinsun.com>
12526 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12527 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12528 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12529 not <inttypes.h>. Problem reported by Tim Mooney in
12530 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12531 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12534 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12535 otherwise "make check" fails because it forbids cmp (I guess
12536 because cmp treats files as binary on DOS-like systems).
12538 * tests/mktests.sh: Update copyright date to 2004, since some tests
12539 have changed in 2004.
12541 2004-01-23 Gary V. Vaughan <gary@gnu.org>

12544 non-truncating sed or gsed program in PATH.

12549 2004-01-15 Paul Eggert <eggert@twinsun.com>
12551 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12552 -std1 disables some useful extensions on Tru64. Problem reported
12553 by N. Lichtmaier in
12554 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12556 2004-01-14 Paul Eggert <eggert@twinsun.com>
12558 * doc/autoconf.texi (Programming in M4sh): Document that
12559 AS_MKDIR_P succeeds if the destination is a symbolic link
12560 to an existing directory.
12561 (Limitations of Usual Tools): Note that mkdir -p might not
12562 succeed on symlinks to directories.
12564 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12566 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12567 * bin/autoheader.in: Grammar fix in message.
12568 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12569 Test for dir before calling mkdir -p. (trivial changes)

12576 2004-01-10 Jim Meyering <jim@meyering.net>
12578 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12580 2004-01-09 Paul Eggert <eggert@twinsun.com>
12582 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12583 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12584 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12585 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12586 AC_COMPILE_IFELSE, since we now assume our caller invokes
12587 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12588 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12589 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12590 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12592 2004-01-07 Paul Eggert <eggert@twinsun.com>
12594 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12595 `"'...'"`, as it's confusing (and I suspect it may not work on
12596 some platforms). The code was incorrect anyway, as it assumed
12597 that \$ evaluated to itself in that context. Reported by
12598 Alexandre Duret-Lutz.
12600 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12602 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12603 and _LT_AC_TAGCONFIG.

12630 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12631 Use "rm -f" to remove conftest.sed, not plain "rm".
12632 Bug reported by David Relson in
12633 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12635 * Makefile.am (autom4te-update):
12636 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

12653 -c -o might not work. From a suggestion by Kevin Ryde.
12654 (C Compiler, Generating Sources, Limitations
12655 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12656 Don't put '-o' after non-options, as POSIX doesn't allow this.
12657 Mention that cc's name might be gcc or c89 or whatever.
12659 2004-01-04 Kevin Ryde <user42@zip.com.au>
12661 * doc/autoconf.texi: Add various further index entries.

12670 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12671 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

12684 * tests/atlocal.in: Store the result here.

12689 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
12690 * tests/tools.at (Syntax of the shell scripts): Simplify

12958 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
12959 -mGLOB_options_string stuff for Intel ifc, which can cause

12983 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
12984 cache variable instead of $G77 to decide whether to include -O2,
12985 since $G77 is specific to Fortran 77.

12989 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
12990 free" flag. Re-order flags tested into rough order of popularity.
12992 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
12994 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
12995 arguments so that it can be used with syntax identical to
12996 AC_PROG_F77, and so that we can more easily decide to
12997 remove/deprecate the DIALECT optional argument in the future if it
12998 proves troublesome.
12999 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13000 non-freeform-supporting compilers. Document freeform flags.
13002 2003-10-03 Akim Demaille <akim@epita.fr>

13064 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13065 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13066 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
13067 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
13069 2003-09-26 Akim Demaille <akim@epita.fr>
13071 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13072 directory for AC_CONFIG_COMMANDS' first argument exists.
13073 This makes valid the invocation of _AC_SRCPATH that follows.
13074 Reported by Eric Sunshine.
13075 * doc/autoconf.texi (Configuration Commands): Adjust.
13077 2003-09-26 Akim Demaille <akim@epita.fr>

13098 The test suite are sometimes assigning timings incorrectly.
13099 Reported by Henk Krus.
13100 Diagnosed by Nicolas Joly.
13102 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13104 Instead of making AT_help a sequence of assignments to grow
13105 $at_help_all, just make AT_help_all be the growing contents of
13106 $at_help_all, and make a single assignment in...
13108 (at_times_skip): Flip the meaning and rename as...
13109 (at_times_p): this.
13110 (AT_INIT): When summarizing the test that ran, remove

13120 (ifnames): chmod -w.
13121 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13122 executables, not bin/ executables! Otherwise all the magic needed
13123 to find non installed files is turned off. This caused a failure
13124 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13125 as found in its environment (sent by tests/autoreconf): pointing
13126 to bin/autom4te that could not find its files.
13127 * tests/mktests.sh: Force the replacement of generated files, for
13128 the sake of "mv" program that are interactive when overwriting a
13130 * config/install-sh: Upgrade from CVS Automake.

13137 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
13138 Paul Eggert <eggert@twinsun.com>
13140 Trivial change to support GCC's configuration procedure.

13181 and AC_FC_FREEFORM.

13203 2003-09-05 Paul Eggert <eggert@twinsun.com>
13205 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

13223 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13225 Add support for newer Fortran dialects. The F77 interface is
13226 unchanged, and continues to support Fortran 77. New FC macros
13227 correspond to all the old F77 macros, with output variables FC,
13228 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13229 available dialect, but older dialects can be specified. There are
13230 new macros AC_FC_SRCEXT to set the source extension, and
13231 AC_FC_FREEFORM to accept free-form source files.
13233 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
13235 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

13357 2003-08-21 Akim Demaille <akim@epita.fr>
13359 First stab at preserving warnings between calls to autom4te,
13360 including when the cache is used.
13362 There are still several issues: (i) there are too many runs of m4
13363 (one for include, one for warnings, and some more), (ii) warnings
13364 spreading on several lines are not handled gracefully, (iii) the
13365 code meant to have the call stack display for errors does not work
13366 (its handling should move from m4 to autom4te).
13368 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13370 (@preselect): Add m4_warn.
13371 ($exit_status): Remove, use $exit_code.
13372 ($help): Use Autom4te::ChannelDefs::usage.
13373 (&handle_m4): No longer define the m4_warnings.
13374 At each run, extract and report the warnings.
13375 Always cache the result, including if the exit status is on
13376 failure, since if nothing changes, we should result in the same
13377 failure, hence we can use the cache.
13378 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13379 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13381 (m4_warn): Redefine as a do-nothing: it is its invocation that
13382 matters, as warnings are now reported via traces.
13383 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13384 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13385 the latter reveals calls to the former.
13389 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

13418 Reported by Alexandre Duret-Lutz.

13422 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13423 * bin/autom4te: Adjust.
13424 In particular, be Autoconf tools are really silent when properly
13425 working, bind the verbosity of the 'note' channel to $verbose.
13426 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13427 (&xsystem, &contents): Remove, since they are exported by...

13548 2003-06-23 Akim Demaille <akim@epita.fr>
13550 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13551 not all of them. This fixes 1. the fact that when testing
13552 Autoconf there are many many config.log, 2. the incorrect use of
13553 top_srcdir to find config.log.
13554 Don't mix the detailed output of failed test with the summary of
13555 failures. Rather, append detailed log afterwards.
13557 2003-06-23 Akim Demaille <akim@epita.fr>
13559 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

13642 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
13644 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
13645 Do not call `_exit()', simply modify `$?'.
13646 (xsystem): Reset $! before running system, and check it afterward.
13647 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
13648 63 for version mismatches.
13650 2003-05-23 Akim Demaille <akim@epita.fr>
13652 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

13674 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13675 Remove `#include <stdlib.h>' from the list; we should never
13676 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13677 resulting namespace pollution would cause other tests to fail.
13678 Configure scripts run with some older versions of g++ and HP's
13679 aCC would fail due to such an #include. Problems reported by
13680 Matthew Mueller in <http://bugs.debian.org/120704> and by
13682 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13683 In the test, use the test declaration before including <stdlib.h>,
13684 as that's closer to how it'll be used.
13686 2003-05-23 Akim Demaille <akim@epita.fr>
13688 * doc/autoconf.texi (Header Portability): ucred.h.
13691 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13693 Overhaul Autotest's logging: generate separate log files
13694 in testsuite.dir/NNN/testsuite.log, and append them to
13695 testsuite.log instead of re-running the test verbosely.
13697 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13698 file descriptor, write 0 to at_status_file instead of setting
13699 at_status=0, initialize some new variables (at_status_file,
13700 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13701 to rerun the tests, instead append the at_group_log to the
13702 at_suite_log when a test fails.
13703 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13704 with the AS_MESSAGE_LOG_FD redirected to stdout.
13705 (AT_CLEANUP): save the output status in $at_status_file
13706 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13707 its original place.
13708 (AT_CHECK): since tests are run with a redirected stdout,
13709 and used to be re-run in verbose mode, turn some $at_verbose
13710 into echo, and don't redirect the output of testing stdout

13837 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13838 by aclocal.m4 is changed it might require the importing of another
13839 m4 extension file, i.e., aclocal must be run.

14117 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

14213 Reported by Ezra Peisach.
14215 2002-11-05 Akim Demaille <akim@epita.fr>
14217 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14219 We _have_ to stop using the old compatibility scheme that tried to
14220 avoid useless backslashes because Libtool 1.4.3 contains a
14221 AC_DEFINE([error_t], [int],
14222 [Define to a type to use for \`error_t' if it is not
14223 otherwise available.])
14224 We _have_ to quote the single quote and backslashes with \. The
14225 old compatibility scheme saw that ` was backslashed, and therefore
14226 did not quote the single quote. Hence before this patch, Autoconf
14227 was not compatible with Libtool.
14229 2002-11-04 Paul Eggert <eggert@twinsun.com>

14618 Reported by Alexandre Duret-Lutz.
14620 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14681 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14682 aclocal invocation, as Gettext macros might not be visible to

14713 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14714 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
14716 2002-09-28 Akim Demaille <akim@epita.fr>
14718 * tests/torture.at (Configuring subdirectories): Be robust to
14719 users who use config.site to require for a cache: in this case,
14720 the two last configure runs, using two different sets of
14721 arguments, trigger a legitimate error.
14723 2002-09-28 Akim Demaille <akim@epita.fr>
14725 * tests/m4sh.at (Functions Support, Functions and return Support):
14728 2002-09-28 Akim Demaille <akim@epita.fr>
14730 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
14731 autoheader are Perl programs.
14732 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
14733 (autom4te): Specify that the sources are in the $srcdir.

14741 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
14742 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
14743 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

14756 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
14757 (.m4.m4f): Don't pass --prepend-include, since that's done by
14758 tests/autom4te itself.
14759 * lib/autoscan/Makefile.am: Include freeze.mk.
14760 (autoscan.list): New target --this file is no longer a source.
14761 (autoscan.pre): New file.
14763 2002-09-28 Akim Demaille <akim@epita.fr>
14765 * bin/autoscan.in (@kinds): Make them singular.
14767 (&init_tables): When --debug, report the list of rules to ease
14768 tracking changes in autoscan.list.
14769 * lib/autoscan/autoscan.list (function): Strip comments, sort.
14771 2002-09-28 Akim Demaille <akim@epita.fr>
14773 * lib/autoscan/functions, lib/autoscan/headers,
14774 * lib/autoscan/identifiers, lib/autoscan/makevars,
14775 * lib/autoscan/programs: Merge into...
14776 * lib/autoscan/autoscan.list: this.
14777 * bin/autoscan.in (&init_tables): Adjust.
14779 2002-09-28 Akim Demaille <akim@epita.fr>
14781 * lib/autoscan/functions, lib/autoscan/headers,
14782 * lib/autoscan/identifiers, lib/autoscan/makevars,
14783 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
14784 `functions' line is now prefixed with `function:'.
14785 * bin/autoscan.in (&init_tables): Adjust.
14787 2002-09-28 Akim Demaille <akim@epita.fr>
14789 From now on, autoscan files must always map a macro name to a
14790 word: there is no `default' macro for autoscan.
14792 * bin/autoscan.in (&init_tables): Reject entries with no macro at
14794 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
14797 2002-09-28 Akim Demaille <akim@epita.fr>
14799 * bin/autoscan.in (%c_keywords): Remove.
14800 (&used): Keep only track of the words we might be interested in.
14801 (&output_kind): It is no longer needed to look for non active
14804 2002-09-27 Akim Demaille <akim@epita.fr>
14806 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

14808 * lib/autoscan/functions: Adjust.
14809 * doc/autoconf.texi (Particular Functions): Adjust.
14811 2002-09-27 Akim Demaille <akim@epita.fr>

14815 Thanks to Bill Moseley and Paul Eggert.
14816 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
14817 the tmpdir must be created.
14818 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
14819 dir be in the build tree, instead of $TMPDIR.
14821 2002-09-27 Akim Demaille <akim@epita.fr>
14823 * bin/autoscan.in: Improve the comments.
14824 (&parse_args): Drop obsolete undocumented options.

14832 Reported by Ralf Corsepius.
14833 * doc/autoconf.texi (autoreconf Invocation): Likewise.
14835 2002-09-26 Akim Demaille <akim@epita.fr>
14837 Single suffix rules and seperated dependencies are not portable.
14839 * doc/autoconf.texi (Installation Directory Variables): Update.
14840 (Limitations of Make): Some about `Single Suffix Rules and
14841 Separated Dependencies'.
14842 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14843 (ifnames, autoscan, autom4te): Un-factor into several rules.
14845 2002-09-25 Paul Eggert <eggert@twinsun.com>
14847 * BUGS (Interoperability bugs): New section. Mention libtool
14848 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
14850 2002-09-24 Paul Eggert <eggert@twinsun.com>
14852 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
14853 make handles suffix-rules differently from GNU make.
14855 * bin/Makefile.am (SUFFIXES, .in): Remove.
14856 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
14857 Move the body of the old .in rule here.
14859 2002-09-16 Akim Demaille <akim@epita.fr>
14861 i960 compilers create `b.out' files by default.
14862 Reported by Ralf Corsepius.
14864 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
14865 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
14867 2002-09-13 Paul Eggert <eggert@twinsun.com>
14869 * doc/autoconf.texi (Particular Headers): Remove obsolete
14870 reference to `struct timezone' in the description of
14873 2002-09-13 Akim Demaille <akim@epita.fr>
14877 * config/config.sub, config/config.guess: Update.
14878 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
14879 * Makefile.am: Adjust.
14881 2002-09-13 Akim Demaille <akim@epita.fr>
14883 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
14884 reading config.log when the compiler is rejected.
14885 Suggested by Guido Draheim.
14887 2002-09-13 Akim Demaille <akim@epita.fr>
14889 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
14890 (chdir_init) might hang when stat'ing mounted directories.
14891 Reported by Vance Shipley.
14893 2002-09-12 Akim Demaille <akim@epita.fr>
14895 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
14898 2002-09-12 Akim Demaille <akim@epita.fr>
14900 * doc/autoconf.texi (Defining Symbols): Present two different
14901 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
14902 difference between 1 argument calls, and 2-3 argument calls.
14904 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
14906 * doc/autoconf.texi: Review grammar and punctuation.
14908 2002-09-11 Paul Eggert <eggert@twinsun.com>
14910 * doc/autoconf.texi: Fix minor formatting, spelling, and
14912 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
14913 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
14916 2002-09-11 Akim Demaille <akim@epita.fr>
14918 * doc/autoconf.texi (Questions): Rename as...
14920 (Defining Directories): New.
14922 2002-09-09 Akim Demaille <akim@epita.fr>
14924 * doc/autoconf.texi (Making testsuite Scripts): Update.
14925 Suggested by Nishio Futoshi.
14927 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
14929 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14930 plain `@' is wanted.
14932 2002-09-09 Akim Demaille <akim@epita.fr>
14934 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14935 `duplicates', since the algorithm was too naive and could keep
14936 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14937 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14938 Reported by Ralf Corsepius.
14939 * tests/torture.at (Configuring subdirectories): Exercise these
14942 2002-09-09 Akim Demaille <akim@epita.fr>
14944 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14945 looking for a replacement file.
14946 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14947 directory is relative.
14948 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14949 directory definition.
14950 Reported by Andreas Schwab and Jim Meyering.
14952 2002-09-06 Akim Demaille <akim@epita.fr>
14954 * doc/autoconf.texi (Setting Output Variables): Clarify what
14955 precious variables are.
14956 Suggested by Pontus Skoeld.
14958 2002-09-05 Akim Demaille <akim@epita.fr>
14960 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14961 (ifnames, autoscan, autom4te): Since we don't only depend on
14962 configure.ac variables (such as VERSION etc.), but also on prefix
14963 and so forth, depend on Makefile, not configure.ac.
14964 Reported by Alexandre Duret-Lutz.
14965 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14967 2002-09-05 Kevin Ryde <user42@zip.com.au>
14969 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14970 doesn't seem to be confined to ia64, just say "some versions".
14972 2002-09-04 Akim Demaille <akim@epita.fr>
14974 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14976 * Makefile.am (maintainer-clean-local): Remove.
14977 (MAINTAINERCLEANFILES): Remove COPYING.
14979 2002-09-03 Paul Eggert <eggert@twinsun.com>
14981 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14982 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14985 2002-09-03 Akim Demaille <akim@epita.fr>
14987 * configure.ac: Bump to 2.53d.
14988 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14989 as of today, on Automake's team suggestion.
14991 2002-09-03 Akim Demaille <akim@epita.fr>
14995 2002-09-02 Akim Demaille <akim@epita.fr>
14997 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14999 * configure.ac: Disable SITE_MACRO_DIR.
15001 2002-09-02 Jim Meyering <meyering@lucent.com>
15003 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15004 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15005 Also, tweak grammar: s/make sure to/be sure to/.
15007 2002-09-02 Paul Eggert <eggert@twinsun.com>
15009 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15010 directory names are generally preferable to physical names.
15012 2002-09-02 Akim Demaille <akim@epita.fr>
15014 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15015 Reported by Raja R. Harinath.
15016 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15017 * bin/autoupdate.in: Use error instead of die.
15019 2002-09-01 Paul Eggert <eggert@twinsun.com>
15021 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15022 ordinary shell concatenation rather than echo+tr+sed command that
15023 runs afoul of a long-line-related sed bug in Solaris 8.
15025 * bin/autoheader.in (parse_args): --warning -> --warnings.
15027 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15028 stdout, as traditional "ls" does.
15029 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15030 _AC_COMPILER_EXEEXT_O): Likewise.
15031 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15033 * bin/autoconf.as: Add --prepend-include option. This patch was
15034 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15035 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15037 * bin/autoconf.in, configure: Regenerate.
15039 * doc/autoconf.texi (Special Shell Variables): Mention
15040 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15042 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15043 MAILPATH and set PS1, PS2, PS4 to default values, to work
15044 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15045 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15046 the Autoconf documentation specifies; fall back to "unset" only if
15047 this fails. Use a shell for-loop for this rather than an m4 loop,
15048 to shorten the output script.
15050 2002-08-30 Paul Eggert <eggert@twinsun.com>
15052 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15053 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15054 for the CDPATH problem. Document PWD.
15055 (Limitations of Builtins): Document the problem that "cd $foo" and
15056 "ls $foo" may refer to different directories in shells conforming
15057 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15058 example, since the old example is now out of date.
15060 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15061 FOO" and "ls FOO" talk about different directories; this catches
15062 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15065 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15066 of rolling our own unset.
15067 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15068 in practice we needn't worry about CDPATH if unset doesn't work.
15070 * Makefile.in, aclocal.m4, bin/Makefile.in,
15071 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15072 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15073 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15074 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15075 tests/Makefile.in: Regenerate with Automake 1.6.3.
15077 * config/config.guess, config/config.sub, config/mkinstalldirs:
15080 * configure: Regenerate with self.
15082 2002-08-30 Kevin Ryde <user42@zip.com.au>
15084 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
15087 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
15089 * bin/autom4te.in (Request::load): Correctly test for "do" read
15092 2002-08-29 Akim Demaille <akim@epita.fr>
15094 * lib/Autom4te/General.pm (&xqx): New.
15095 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15096 hand, which is not portable.
15098 * bin/autom4te.in: Use them.
15099 Use &error instead of die.
15100 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15103 2002-08-17 Paul Eggert <eggert@twinsun.com>
15105 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15106 default list of compilers to try, since it was long ago superseded
15107 by the ksh fc builtin. Suggested by Steven G. Johnson.
15109 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15111 * doc/autoconf.texi (Invoking autom4te): End the option table,
15112 fixing a bug introduced by the previous patch.
15113 (Limitations of Make): Add a 'target lookup' subentry in the
15114 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15116 2002-07-29 Mark D. Roth <roth@feep.net>
15118 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15119 options and use $AUTOM4TE_PATH.
15120 * doc/autoconf.texi: Remove documentation of autom4te
15121 --include-envvar and --site-macro-subdir options and document
15122 use of $AUTOM4TE_PATH.
15123 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15124 arguments from each language section.
15126 2002-07-29 Paul Eggert <eggert@twinsun.com>
15128 * doc/install.texi: Include copyright symbol in copyright notice.
15130 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15132 (AM_MAKEINFOFLAGS): New macro.
15133 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15134 * Makefile.am (INSTALL): Use the new macros.
15135 Use -o rather than --output, since "missing" does not grok --output.
15137 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15139 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15140 comments do not always work. Never trust the exit status of
15143 2002-07-24 Kevin Ryde <user42@zip.com.au>
15145 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15146 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15148 2002-07-23 Paul Eggert <eggert@twinsun.com>
15150 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15151 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15152 apparently treats PATH="nonexistent" as if it contained ".".
15153 Bug reported by Stefan `Sec' Zehl.
15155 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15157 * doc/autoconf.texi (Limitations of Make): Mention the special
15158 handling of the obj/ directory by BSD make.
15160 2002-07-20 Kevin Ryde <user42@zip.com.au>
15162 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

15184 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

15191 2002-07-18 Akim Demaille <akim@epita.fr>,
15192 Alexandre Duret-Lutz <duret_g@epita.fr>
15194 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
15195 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

15279 2002-06-27 Paul Eggert <eggert@twinsun.com>
15281 * config/install-sh: Quote $src. Prefer || to test's -o option,
15282 as per "Limitations of Builtins".

15423 This improves on an earlier suggestion by H. Peter Anvin.
15425 2002-05-16 Paul Eggert <eggert@twinsun.com>
15427 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15428 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15429 Both macros now accept an optional source-dir arg.
15430 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15432 * NEWS: Document this.
15433 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15435 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15436 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15437 not for GNU extensions; this undoes part of the 2000-11-03 change,
15438 reverting to 2.13-compatible behavior.

15446 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15447 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15448 and it causes a 'test' syntax error if it fails.
15449 Bug reported by Stephen Gildea.
15451 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15452 If prototypes are supported, use them to check this at compile-time,
15453 instead of trying to check it at run-time. If we must do a run-time
15454 check, assume that setvbuf is standard when cross-compiling, as
15455 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15456 Bug reported by Paul D. Smith.
15458 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15459 argument specifying location of getloadavg.c. This removes a
15460 FIXME. This idea was taken from Jim Meyering's implementation in
15462 * doc/autoconf.texi (Particular Functions): Document this.
15463 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15464 that's what the code does; this fixes a bug reported by
15467 2002-05-03 Akim Demaille <akim@epita.fr>
15469 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15470 autopoint instead of gettextize.
15471 ($uses_alocal): Rename as...
15472 ($uses_aclocal): this.
15473 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15474 Suggested by Bruno Haible.
15476 2002-05-03 Akim Demaille <akim@epita.fr>
15478 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
15480 2002-04-29 Paul Eggert <eggert@twinsun.com>
15482 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15483 files to be 1 second older; just set them to be the same time.
15484 Also, sleep 1 second after the first aclocal, to work around
15485 problems with sub-second time stamps on the input files.
15487 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15489 * doc/autoconf.texi: Mention "set -e -x" lossage
15490 under node "Limitations of Builtins".

15496 From Christian Cornelssen.
15498 2002-04-29 Akim Demaille <akim@epita.fr>
15500 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15501 of lack of $LINENO support, then the test will compare the $LINENO
15502 in testsuite vs. the lineno in the test file. This is wrong, of
15504 Be sure to protect it.
15505 Reported by Patrick Welche.
15507 2002-04-25 Akim Demaille <akim@epita.fr>
15509 * doc/autoconf.texi (Obsolete Macros): Typo.
15510 Reported by Vladimir Volovich.
15512 2002-04-25 Akim Demaille <akim@epita.fr>
15514 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15515 than some of the input files, hence, on the second run of aclocal,
15516 if some of its input are younger, make them older.
15517 Suggested by Paul Eggert.
15519 2002-04-25 Akim Demaille <akim@epita.fr>
15521 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15526 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
15527 and ac_subst_vars be sh variables containing the list of
15528 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15530 (_AC_INIT_PREPARE): Use them to log them.
15531 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15532 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15533 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15534 _AC_SUBST_FILES and _AC_SUBST_VARS.
15535 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15537 2002-04-24 Akim Demaille <akim@epita.fr>
15539 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15540 autoheader, so that automake does not complain about a missing
15541 config.h.in that was to be created.
15543 2002-04-23 Akim Demaille <akim@epita.fr>

15690 Reported by Ezra Peisach.
15692 2002-04-04 Andreas Schwab <schwab@suse.de>
15694 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
15695 contains no literal separators.
15697 2002-04-03 Akim Demaille <akim@epita.fr>
15699 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
15700 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
15701 Use dnl, not the KILL diversion.
15703 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15704 (AC_CONFIG_LINKS): here.
15706 Don't use the KILL diversion, as it kills spurious output, which
15707 results in failures being hidden.
15708 Use m4_defn where appropriate.
15709 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15710 after the second argument.
15712 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15713 syntax, as it is provided by M4sugar.

15719 expanded if $# <= 2.

15730 (_AC_COMPILER_OBJEXT): Use them.
15731 Fixes Debian #138666.
15733 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
15735 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
15737 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
15738 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
15739 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
15740 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
15741 (AC_C_CONST): Same.

15755 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15756 to avoid versions of HP C which don't allow that.
15758 2002-03-27 Paul Eggert <eggert@twinsun.com>
15760 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
15761 (AS_SHELL_SANITIZE): Invoke it.

15772 2002-03-25 Paul Eggert <eggert@twinsun.com>
15774 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15775 as POSIX requires, as it doesn't work with Zsh.
15776 * doc/autoconf.texi (Assignments): Document the problem.
15778 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

15786 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15787 problem with here-document buffer boundaries.
15789 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15790 when reinvoking the shell, to work around problems with installers
15791 who put strange things like "cd" commands in their environments.

15811 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

15816 (Limitations of Usual Tools): Add mkdir section.
15818 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15819 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15820 back on AS_DIRNAME to compute prefixes otherwise; this is
15821 roughly what mkinstalldirs does. That way, we need not have
15822 our own filename disassembler. The old disassembler did not
15823 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15825 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15826 Create at_test_all by a series of assignments,
15827 not by a single assignment of a long string. The latter causes ksh
15828 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15829 presumably because of a buffer overrun.
15831 2002-03-14 Paul Eggert <eggert@twinsun.com>
15833 * lib/autotest/general.m4 (at_times_skip):
15834 Renamed from at_times. Now a boolean.
15835 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15836 says 'times: not found'.
15838 2002-03-14 Akim Demaille <akim@epita.fr>
15840 * bin/autoreconf.in (&study_gettextize): New.
15841 (&autoreconf): Handle newest gettextize.

15865 2002-03-11 Andreas Schwab <schwab@suse.de>

15868 does not do it if --with-lispdir is given.

15877 subdirectory should exist.
15879 2002-03-08 Akim Demaille <akim@epita.fr>
15881 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15883 2002-03-08 Akim Demaille <akim@epita.fr>
15885 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15886 aliases the actual variables, and modifications of the former
15889 2002-03-08 Akim Demaille <akim@epita.fr>
15891 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15892 because of C-c: have m4 output in tmp files, then mv them.

15915 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
15916 * lib/autoconf/general.m4 (AC_INIT): More informative error
15917 message for LIBOBJ.
15919 2002-03-04 Akim Demaille <akim@epita.fr>

15924 2002-03-04 Akim Demaille <akim@epita.fr>
15926 * doc/autoconf.texi (Transforming Names): Equality between target
15927 and host is irrelevant.
15928 (Specifying Names, Canonicalizing): Remove all references to the
15929 backward compatibility hooks. Rather, collect them all into...
15930 (Hosts and Cross-Compilation): this new section.
15931 * doc/install.texi (System Type): Ditto.
15932 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15933 that `--host' implies cross-compilation.
15935 2002-03-04 Akim Demaille <akim@epita.fr>
15937 * doc/autoconf.texi (Evaluation Macros): New.
15938 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
15940 (_m4_foreach): Define the variant with immediate evaluation so
15941 that it contains exactly the items, not an expression which
15942 evaluation is the current item.
15943 (m4_re_string, m4_re_word): Don't over quote them.
15945 2002-03-04 Akim Demaille <akim@epita.fr>
15947 Instead of having stacking `shift's evaluated at the end, let
15948 `foreach' loops immediately evaluate them.
15950 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15951 $*. This is the n-th time I change my mind, but hopefully this is
15954 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15956 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15957 it was only a hack for m4_text_wrap.
15958 (m4_car2): Remove, replaced by...
15960 (_m4_foreach): Adjust.
15961 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15962 m4_bpatsubst for clarification.

16013 Fix Autoconf PR/207:
16014 AC_PREFIX_PROGRAM fails with dashed program names
16016 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

16078 optional are the sum of the previous files on the command line'.
16079 Also, pass `--reload-state=' on them, so...
16080 (handle_m4): don't.
16081 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
16082 (M4sh): Rely on M4sugar.
16083 (Autotest, M4sh, M4sugar): Use frozen files.

16113 Reported by Alexandre Duret-Lutz and Larry Schmitt.
16115 2002-01-28 Akim Demaille <akim@epita.fr>
16117 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
16120 2002-01-28 Akim Demaille <akim@epita.fr>
16122 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
16123 AUTOTEST_PATH *after* it was set.
16124 Don't put `.' in the PATH: the user should be precise and `./' if
16125 needed. In addition, given that the test suite does some `cd', if
16126 `.' is in the path, the `tested programs' sections will report
16127 programs found in the test suite's directory, while during the
16128 tests (performed in their own directory), these programs are no
16129 longer visible. In other words, the results is confusing and

16194 2002-01-06 Akim Demaille <akim@epita.fr>
16196 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
16197 package.m4, since is really depends upon configure.ac, not
16199 * doc/autoconf.texi (testsuite Scripts): Adjust.
16200 * tests/Makefile.am (package.m4): New.
16201 EXTRA_DIST it since its a source.
16203 2002-01-06 Akim Demaille <akim@epita.fr>
16205 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
16206 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16207 and PACKAGE_BUGREPORT from here...
16208 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16210 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16211 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
16212 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
16213 * tests/tools.at (autoheader): Adjust.
16214 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
16216 2002-01-06 Akim Demaille <akim@epita.fr>

16222 * doc/autoconf.texi (Output): Improved wording regarding use of
16226 2001-12-18 Kevin Ryde <user42@zip.com.au>
16228 * doc/autoconf.texi (Function Portability): Add notes on sscanf
16229 sometimes needing writable input.
16231 2001-12-17 Jim Meyering <meyering@lucent.com>
16233 * doc/autoconf.texi (New Macros): Tweak wording.
16235 2001-12-14 Akim Demaille <akim@epita.fr>
16237 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16238 trailing files, don't apply `-rf' to files which might not be
16239 created by configure (core, core.*, and *.core), but just `rm -f'.
16240 Suggested by Jonathan Kamens.
16242 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
16244 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
16246 2001-12-14 Akim Demaille <akim@epita.fr>
16248 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
16250 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
16252 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
16253 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
16254 abs_srcdir, top_srcpath to abs_top_srcdir.
16255 (_AC_OUTPUT_FILES): Adjust.
16256 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
16257 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
16258 * tests/wrappl.in, tests/wrapsh.in: Adjust.
16260 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
16262 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
16263 C/Fortran linking on HP/UX, by extracting the Fortran library
16264 search path from the LPATH line in the $F77 -v output.
16266 2001-12-12 Kevin Ryde <user42@zip.com.au>
16268 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
16269 forbidden file descriptors table.
16271 2001-11-26 Akim Demaille <akim@epita.fr>
16273 * bin/autoscan.in (%c_keywords): Build it at top level.
16274 Map to 1 in order to simplify its uses.
16276 2001-11-26 Akim Demaille <akim@epita.fr>
16278 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
16279 Remove $filepath, useless.
16280 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
16281 variables, they are really part of the tokens.
16282 Split the input line on spaces and then look for tokens.
16283 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
16284 because of `lex$U.$(OBJEXT)'.
16285 (&scan_files): Use "@list" instead of join.
16286 * doc/Makefile.am (CLEANFILES): Add *.fns.
16288 2001-11-26 Akim Demaille <akim@epita.fr>
16290 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
16291 Remove, replaced by...
16292 * tests/wrappl.in: Be common for all the Perl executables.
16293 In particular autoscan and autoheader want -I.
16294 * configure.ac: Adjust.
16295 * lib/autoscan/headers: errno.h is portable.
16297 2001-11-26 Akim Demaille <akim@epita.fr>
16299 * bin/autoscan.in (used): New.
16302 2001-11-26 Akim Demaille <akim@epita.fr>
16304 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
16306 (&scan_sh_file): Remove a duplicate pattern.
16307 (&check_configure_ac): Use long options.
16308 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
16310 2001-11-26 Akim Demaille <akim@epita.fr>
16312 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
16313 Before, having a line containing the opening of a multi line
16314 comment made the whole line be ignored.
16316 2001-11-26 Akim Demaille <akim@epita.fr>
16318 * doc/autoconf.texi (Using an Autotest Test Suite): New.
16319 (testsuite Scripts): Be one of its subsection.
16320 (Autotest Logs): New.
16322 2001-11-26 Akim Demaille <akim@epita.fr>
16324 Test groups are now run two directories deeper.
16326 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16327 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16329 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16330 top_srcdir, builddir and top_builddir.
16331 Use `at_*dir' relatively to the directory containing the
16332 suite, use `*dir' when relatively to the current group dir.
16334 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
16336 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
16337 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
16338 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
16341 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16343 * doc/autoconf.texi (Using System Type): Add an example of `case
16344 $host' usage so people quit using `case $target' everywhere.
16346 2001-11-22 Akim Demaille <akim@epita.fr>
16348 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16349 spotted by Jim Meyering.
16351 2001-11-16 Paul Eggert <eggert@twinsun.com>
16353 This patch implements a `long double' suggestion by Oliver Kiddle.
16355 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16356 static, to catch errors if the value isn't known at compile-time
16357 and the compiler supports dynamic arrays. Change its name from
16358 `_array_' to `test_array' to avoid potential name clashes.
16359 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16360 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16361 better than double. Catch a bug in GCC 2.95.2 x86.
16362 * doc/autoconf.texi (C Compiler): Document the above.
16365 2001-11-13 Akim Demaille <akim@epita.fr>
16367 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16369 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16371 2001-11-13 Akim Demaille <akim@epita.fr>
16373 * lib/autotest/general.m4 (AT_INIT): After having run the test
16374 group, go back to the initial directory, not to at_suite_dir.
16376 2001-11-13 Akim Demaille <akim@epita.fr>
16378 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16379 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16380 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16382 (AT_CHECK_CONFIGURE): Use absolute paths.
16383 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16384 The problem is still the old one: there is no means in M4 (that I
16385 know about) to create a defining macro, because there is no means
16386 to create `$1' etc., therefore, the defining macro ``swallows''
16387 all the arguments meant to the defined macro.
16389 2001-11-13 Akim Demaille <akim@epita.fr>
16391 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16392 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16394 * tests/aclocal.m4: Remove, as it is no longer used.
16396 2001-11-13 Akim Demaille <akim@epita.fr>
16398 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16399 variable names when referring to a single test group, or to
16400 `suite' when referring to the whole test suite.
16401 `at_last_test' is removed: m4 compute at_format itself.
16402 (at_stdout, at_stder1, at_stderr): New variables.
16403 (AT_CHECK): Use them.
16405 2001-11-13 Akim Demaille <akim@epita.fr>
16407 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16409 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16410 Do it as soon as a test fails, don't wait till the end of the test
16412 Don't remove $as_me.[0-9]*, since these files no longer exist.
16414 2001-11-13 Akim Demaille <akim@epita.fr>
16416 * tests/tools.at: Use absolute paths, since we are no longer run
16419 2001-11-13 Akim Demaille <akim@epita.fr>
16421 Now that tests are running in their own private dir, there is no
16422 need to list the files to remove at the end of tests groups.
16424 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16425 (AT_data_files, at_data_files): Remove.
16426 (AT_CLEANUP, AT_DATA): Simplify.
16428 Remove the group dir if !debug && !failed.
16429 * tests/atspecific.m4: Adjust.
16431 2001-11-13 Akim Demaille <akim@epita.fr>
16433 Start a new layout for Autotest: `testsuite' creates
16434 `testsuite.dir' in which the at-check-line etc. files are to be
16435 found, and `testsuite.dir/003' where the test group 3 is run.
16437 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16438 at_check_line_file, at_format, at_test_normalized, at_group_dir
16440 Create the directories.
16441 Use absolute paths for at- files.
16442 (AT_CHECK): Adjust.
16444 2001-11-11 Michael Matz <matz@kde.org>
16446 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16448 (m4_car): Properly quote arguments.
16450 2001-11-13 Akim Demaille <akim@epita.fr>
16452 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16453 with stricter rules on LIBOBJS.
16455 2001-11-12 Paul Eggert <eggert@twinsun.com>
16457 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16458 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16461 2001-11-12 Akim Demaille <akim@epita.fr>
16463 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16465 2001-11-12 Akim Demaille <akim@epita.fr>
16467 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16468 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16469 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16470 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16471 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16472 specify to what the macro should be defined (typically to 1).
16474 2001-11-12 Akim Demaille <akim@epita.fr>
16476 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16479 2001-11-12 Akim Demaille <akim@epita.fr>
16481 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16482 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16483 definition used by Automake where LEX is +/- "${missing} lex" and
16484 `missing' itself contains variables.
16486 2001-11-12 Akim Demaille <akim@epita.fr>
16488 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16489 Now that M4sh pushes BODY, the comments were output at the end of
16492 2001-11-08 Akim Demaille <akim@epita.fr>
16494 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16495 that we can trace macros from aclocal.m4.
16496 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16497 obsoleted, and redirect to the former anyway.
16498 Reported by Ralf Corsepius.
16500 2001-11-08 Akim Demaille <akim@epita.fr>
16502 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16503 processed only if present.
16504 * tests/torture.at (Configuring subdirectories): Use autoreconf
16505 instead of successive calls to autoconf.
16506 Add a nonexistent subdirectory to exercise the patch above.
16507 Reported by Ralf Corsepius.
16509 2001-11-08 Kevin Ryde <user42@zip.com.au>
16511 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16512 doesn't accept .S files.
16514 2001-11-07 Akim Demaille <akim@epita.fr>
16516 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
16517 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
16518 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16519 * bin/autom4te.in (warn_forbidden): New.
16520 (handle_output): Use it.
16521 Read m4_pattern_forbid with messages.
16523 2001-11-05 Akim Demaille <akim@epita.fr>
16525 * bin/autom4te.in (--normalize): Remove.
16526 * lib/autom4te.in: Adjust.
16528 2001-11-05 Akim Demaille <akim@epita.fr>
16530 * tests/Makefile.am (testsuite): Rename this target as...
16531 ($(TESTSUITE)): this.
16534 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16536 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16537 the --prefix option, also remove it's argument.
16539 2001-11-05 Akim Demaille <akim@epita.fr>
16541 * doc/autoconf.texi (testsuite Invocation): Update.
16542 (Writing testsuite.at): Update.
16544 2001-11-03 Akim Demaille <akim@epita.fr>
16546 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16548 2001-11-03 Akim Demaille <akim@epita.fr>
16550 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16551 (&file_name_is_absolute): New, wrappers around routines from
16553 Use and export them.
16554 (&find_configure_ac): Optionally take a directory where to look at.
16555 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16557 Default @ARGV to `.', not find_configure_ac.
16558 (&autoreconf): Argument is a directory.
16559 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16560 * doc/autoconf.texi (autoreconf Invocation): Update.
16562 2001-11-03 Akim Demaille <akim@epita.fr>
16564 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16565 (@export_forward_subs): New.
16566 Add basename, dirname, and fileparse.
16568 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16569 Don't look for aclocal flags if we already know aclocal is not
16571 Move aclocal.m4t only if it exists.
16572 Reported by Ezra Peisach.
16574 2001-11-03 Akim Demaille <akim@epita.fr>
16576 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16577 passed on command line, defaulting to ./configure.ac if present.
16578 (&maybe_autoreconf, File::Find): Remove, unused.
16579 (&autoreconf): If autoconf is not used, don't try to trace.
16581 2001-11-02 Akim Demaille <akim@epita.fr>
16583 * configure.ac: Bump to 2.52g.
16585 2001-11-02 Akim Demaille <akim@epita.fr>
16589 2001-11-02 Akim Demaille <akim@epita.fr>
16591 * config/config.guess, config/config.sub, doc/standards.texi:
16592 * config/lispdir.m4: Update from masters.
16593 * configure.ac: Bump to 2.52f.
16595 2001-11-02 Akim Demaille <akim@epita.fr>
16597 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16598 Don't run aclocal when aclocal.m4 is not from aclocal.
16600 Don't run libtoolize and gettextize if --install is not given.
16602 2001-11-01 Paul Eggert <eggert@twinsun.com>
16604 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16605 be invoked before _AS_LINENO_PREPARE.
16606 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16607 than character ranges.
16609 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16610 invoking AS_BASENAME. Set the locale variables to 'C' if
16611 possible, as POSIX requires this to get the traditional
16613 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16615 2001-10-31 Paul Eggert <eggert@twinsun.com>
16617 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16618 with {}, as that triggers a bug in Bash 2.05.
16620 (_AS_LINENO_PREPARE): Use Sed rather than
16621 Awk. Fix the sed prepass to work even if there are multiple
16622 instances of $LINENO on the same line. Do not substitute for
16623 other variables like $LINENOT. Do not check file dates; such a
16624 check is unreliable on sufficiently fast machines, and removing
16625 the check makes the code simpler and more reliable. Check for
16626 output and chmod failures.
16628 * doc/autoconf.texi (Special Shell Variables): Document
16631 2001-10-31 Akim Demaille <akim@epita.fr>
16633 * tests/Makefile.am (atconfig): Remove this target, Automake
16636 2001-10-31 Akim Demaille <akim@epita.fr>
16638 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16639 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16640 provided, while it is optional.
16641 * configure.ac: Adjust.
16643 2001-10-26 Paul Eggert <eggert@twinsun.com>
16645 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16646 lib/Autom4te/Struct.pm:
16647 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16650 * doc/autoconf.texi (Special Shell Variables): Document some
16651 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16653 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16654 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16655 eval $LINENO is not portable in practice.
16657 2001-10-24 Akim Demaille <akim@epita.fr>
16659 * lib/Autom4te/General.pm (backname): New.
16661 2001-10-24 Akim Demaille <akim@epita.fr>
16663 * m4/: Remove, merged into...
16666 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
16668 * doc/autoconf.texi (Shellology): Mention the problems with bash
16669 2.05's use of ANSI quoting in its `set' builtin.
16671 2001-10-22 Paul Eggert <eggert@twinsun.com>
16673 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16674 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16675 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16676 POSIX decided to standardize on the int flavor of strerror_r.
16677 Always do char* test, as there's no reason not to.

17173 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
17174 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
17175 be used instead of ':'.
17176 * lib/autotest/general.m4: Replace occurrences of ':' in
17177 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
17179 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17181 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
17182 arguments. Fixed a typo.
17184 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17186 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
17187 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
17189 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17191 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

17198 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17200 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
17201 already have $file). Set output files to binary mode (helps avoid
17202 CR issues on DOSish systems).
17204 2001-09-19 Akim Demaille <akim@epita.fr>
17206 * lib/autotest/general.m4: Englishoes.
17207 From Tim Van Holder and Alexey Mahotkin.
17209 2001-09-18 Paul Eggert <eggert@twinsun.com>
17211 * doc/autoconf.texi (Common Shell Constructs): New node,
17212 documenting AS_DIRNAME.
17213 (Limitations of Usual Tools): Refer to it when discussing dirname.
17214 Also, update discussion of POSIX standard to reflect latest draft.
17216 * lib/autoconf/c.m4:
17217 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17219 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17220 Do not pass a first argument with leading '-'
17221 to expr, by parenthesizing initial integers that might be negative.
17223 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17224 now merely checks whether it is an error to pass an argument
17227 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17228 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17229 whether it is a (compile-time) error to pass an argument to
17230 getpgrp. This simpler test supports the revised documentation,
17231 and is all that AC_FUNC_GETPGRP's users really need.
17233 2001-09-18 Akim Demaille <akim@epita.fr>
17235 * doc/autoconf.texi (Limitations of Make) <$<>: New.

17245 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17247 Add test for AS_BASENAME.
17248 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17249 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17250 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17251 * tests/base.at: Fixed the expected responses. The old ones were
17253 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17254 the documentation claims it should (and how it behaved in 2.13).
17256 2001-09-18 Akim Demaille <akim@epita.fr>
17258 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17259 the AC_CONFIG_COMMANDS invocation.
17260 This also solves the name clash problems.
17261 Don't set the package's ID.
17262 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17263 No longer to be shipped.
17264 (version.in): Remove.
17265 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
17266 * lib/autoconf/status.m4: Adjust.
17267 Use `m4_PACKAGE_STRING'.
17268 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17269 the only optional argument is the name of the test suite.
17270 Expect `package.m4' to define the package signature.
17271 * lib/autom4te.in (Autotest): Add `package.m4?'.
17272 * tests/Makefile.am (package.m4): New.
17273 * tests/suite.at: ifnames is a victim.
17275 2001-09-18 Akim Demaille <akim@epita.fr>
17277 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17278 AC_LIBSOURCE, AC_CONFIG_FILES.
17279 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
17280 program version string doesn't match the package's.
17281 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
17284 2001-09-17 Paul Eggert <eggert@twinsun.com>
17286 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17287 Allow expression to return any value that can fit into unsigned long
17288 (not int, as before). Check for output errors.

17292 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17293 Always include <stdio.h> and <stdlib.h>. Evaluate
17294 the expression in an extra function before these includes. Call
17295 fprintf "%d" only after ensuring the argument is of type 'int'.
17296 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17298 2001-09-17 Paul Eggert <eggert@twinsun.com>
17300 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17301 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17302 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17303 when they don't exist.
17305 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17306 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17309 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17310 version with the version used by fileutils 4.1, except use
17311 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
17314 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
17316 2001-09-13 Akim Demaille <akim@epita.fr>

17356 * lib/autotest/general.m4 (AT_INIT): Create and remove
17357 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
17358 test suites can cohabit.
17360 2001-09-13 Akim Demaille <akim@epita.fr>
17362 * tests/mktests.sh: Don't output banners for empty test files.

17468 2001-09-05 Akim Demaille <akim@epita.fr>
17470 Be ready to handle filenames as stupid as `dnl.at', for if even
17471 the maintainer is dumb enough to do that...
17473 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17474 excellence in M4 quotation: consider `__file__' is active.
17476 And BTW, when invoking m4, pass the --include in the right order:

17558 autom4te_perllibdir.

17562 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

17624 * bin/autoconf.in (--include, -I): New option.
17625 Map --localdir, --autoconf-dir onto it.
17626 Forward autom4te's options instead of interpreting them.
17627 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
17628 There is no such envvar since the inception of autom4te.cfg.
17629 * bin/autom4te.in (&parse_args): Uniquify `@include'.
17630 * bin/autoupdate.in: Adjust, and perform more control.
17631 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
17632 * tests/autoconf: Dittowise.
17634 2001-08-31 Akim Demaille <akim@epita.fr>
17636 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
17637 * bin/autom4te.in (&find_file): Support `FILE?' standing for
17639 Use -e, not -f, since /dev/null for instance is OK.
17640 (&parse_args): Adjust.
17641 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

17650 * lib/Autom4te/General.pm (&find_peer): Remove.
17651 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
17652 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
17653 * man/Makefile.am: Let help2man rely on PATH instead of trying to
17654 find the executables for it.
17655 * tests/Makefile.am: Major cleanup. Too lazy to document...
17656 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17658 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17659 indeed related to running the test suite, while passing
17660 --autoconf-dir and others is related to running non installed
17661 Autoconf executables. So don't do that, leave it to...
17662 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
17663 * tests/autoscan: New.
17664 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

17681 Suggested by Paul Eggert.
17683 2001-08-29 Akim Demaille <akim@epita.fr>
17685 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
17686 download in a tmp dir.
17688 2001-08-29 Akim Demaille <akim@epita.fr>

18072 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

18090 * doc/autoconf.texi: Work around Texinfo buglets.
18091 (Transformation Rules): One example is enough, users are expected

18140 2001-08-15 Akim Demaille <akim@epita.fr>
18142 * Makefile.maint (CVS): New.
18143 (local-check): Run changelog-check. last.

18145 (cvs-dist): depends upon it.
18147 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
18149 * tests/Makefile.am: Use a clean-local rule to remove
18150 autom4te.cache (it's a directory, not a file.
18151 * Makefile.am: Ditto (but maintainer-clean-local).
18153 2001-08-15 Akim Demaille <akim@epita.fr>
18155 * bin/autom4te.in (@m4_warning): New.
18156 (&handle_m4): Use it.
18157 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
18158 warnings are issued at each run.
18159 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
18160 is in the src tree.
18162 2001-08-15 Akim Demaille <akim@epita.fr>
18164 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
18165 don't waste time running `autoupdate --version' works.
18166 * tests/tools.at (autoupdating AC_PREREQ): Likewise.

18236 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
18237 magic values from an object file when cross-compiling.
18238 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
18240 2001-08-10 Akim Demaille <akim@epita.fr>
18242 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18244 Suggested by Russ Allbery.
18246 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18248 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18249 current $prefix to the sub-configures.
18251 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
18253 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
18254 extension (needed on BeOS). Reported by Guido van Rossum.
18256 2001-08-09 Akim Demaille <akim@epita.fr>
18258 * bin/autom4te.in ($icache): Load it only if older than autom4te.
18260 2001-08-07 Akim Demaille <akim@epita.fr>
18262 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
18264 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18265 No need to remove the files before and after the each test, before
18266 each test and at the end of the suite is enough.
18267 Display only the children `times', not the shell's.
18268 If the test failed or was skipped, at-times is not available.
18270 2001-08-07 Akim Demaille <akim@epita.fr>
18272 Always produce testsuite.log, including when there are no
18273 failures. This helps getting information on skipped tests, and
18274 duration of the tests. Err, implement the latter btw.
18276 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
18277 Dump information on the first run of each test.
18278 (AT_CLEANUP): Create `at-times' containing the duration of the
18281 2001-08-07 Akim Demaille <akim@epita.fr>
18283 The use of `dumpstat' revealed that `len' was used although it
18284 should not. m4_text_wrap was using it, but in the Autoconf world
18285 where it is legal. Hence (i) test M4sh in its own world, not
18286 Autoconf's, and (ii), ahem, fix the bug :)
18288 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18289 does not like `' instead of [].
18290 (AT_INIT): Forbid `^_?AT_'.
18291 And don't output such tokens.
18292 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
18293 `script.as', and `autom4te.cache'.
18294 Remove `empty' and `macro' which are no longer used.
18295 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
18296 * tests/m4sugar.at: Use it.
18297 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
18299 2001-08-07 Akim Demaille <akim@epita.fr>
18301 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
18303 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
18305 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
18307 2001-08-04 Akim Demaille <akim@epita.fr>
18309 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
18310 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
18312 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
18313 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
18314 (AC_F77_MAIN): Likewise.
18316 2001-08-04 Akim Demaille <akim@epita.fr>
18318 Don't rely on M4sugar outputting the patterns in files, since we
18319 might process the output _without_ running m4, hence without these
18322 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18323 * bin/autom4te.in (@Request::includes): Remove, unused.
18324 (@Request::source): Rename as...
18325 (@Request::input): this.
18326 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
18327 (&handle_output): Fetch the patterns from the traces.
18328 `$forbidden' and `$allowed' are constant: use m//o.
18329 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18330 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18332 2001-08-04 Akim Demaille <akim@epita.fr>
18334 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18335 autoconf', i.e., in addition to caching traces, cache the output.
18337 * bin/autom4te.in (Request::cache): Rename as...
18338 (Request::id): this.
18339 ($cache, $icache, $tcache, $ocache): New.
18340 (&handle_m4): Save M4 output in the cache instead of $tmp.
18341 (&handle_output): Adjust.
18342 (&up_to_date_p): Check that the output cache is up to date too.
18343 (top level): Run `&handle_m4' iff force or the cache is invalid.
18344 Run `&handle_output' if the output cache is more recent.
18346 2001-08-04 Akim Demaille <akim@epita.fr>
18348 * bin/autom4te.in ($force): New.
18349 (&parse_args, &print_usage): -f, --force is a new option.
18350 (&handle_output): CPP directives might have spaces after `#'.
18351 (&parse_args): The first file only can be frozen.
18353 2001-08-04 Akim Demaille <akim@epita.fr>
18355 Don't let autom4te compute the `include' traces several times:
18356 first check that the trace cache file is up to date, and then
18357 compare its timestamp with that of the output.
18359 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18360 the preamble. Don't require 5.005 as Autom4te::General does it,
18361 and better yet (use `use', not `require'!).
18362 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18363 Class::Struct as Autom4te::Struct.
18364 * lib/Autom4te/General.pm (File::stat): Use it.
18365 (&mtime): New, export it.
18366 * bin/autom4te.in: Use it.
18367 Declare `$req' is invalid if it is outdated.
18368 Don't declare it valid before saving it if something went wrong.
18370 2001-08-04 Akim Demaille <akim@epita.fr>
18372 Autom4te shall not encode Autoconf data, and preselecting traces
18373 must be proposed to the users.
18375 * bin/autom4te.in (@required_trace): Remove.
18377 (&parse_args, &print_usage): -p, --preselect is a new option.
18378 (&up_to_date_p): Adjust.
18379 * bin/autoconf.in: Preselect some Autoconf macros.
18381 2001-08-04 Akim Demaille <akim@epita.fr>
18383 * tests/tools.at (autoconf --trace: user macros): Check traces on
18384 macros invoked without arguments, and macros invoked with multiple
18387 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

18392 2001-08-03 Akim Demaille <akim@epita.fr>
18394 * bin/autoconf.in ($@): Work around the usual sh bug.
18397 2001-08-03 Akim Demaille <akim@epita.fr>
18399 Clean up the handling of the M4 builtins tracing exception.
18401 * bin/autom4te.in (Request::request): Don't complete M4 builtins

18404 (@m4_builtin): this.
18405 (%m4_builtin_alternate_name): New.
18406 (&parse_args): Complete the trace requests with alternate names.
18407 (&handle_traces): Hence no longer do it here.
18408 (&trace_requests): Remove, unused.

18412 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
18413 m4_if, and m4_wrap.
18415 2001-08-03 Akim Demaille <akim@epita.fr>
18417 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
18418 (m4_divert_pop): Dump the whole diversion stack when a diversion
18420 * bin/autom4te.in (&handle_output): Remember of the first
18421 occurrence of a possibly undefined macro, not the last.
18422 Complain about the possibly undefined macros in the same order as
18423 the appear in the output.
18424 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18425 * tests/tools.at (autoconf: forbidden tokens, basic)
18426 (autoconf: forbidden tokens, exceptions): No longer sort
18427 autoconf's stderr, as it is now deterministic.
18428 Check that `dnl' is caught.
18430 2001-08-01 Akim Demaille <akim@epita.fr>
18432 * configure.ac: Bump to 2.52c.

18449 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
18450 `END', as `Autom4te::General::END' will be triggered.
18451 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18452 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
18453 system to run `mv', `rm', and `cmp'.
