5462 font-lock. Create $TMPDIR before it might be used.
5464 Fix spurious testsuite failure with M4 1.4.11.
5465 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5467 Optimize AC_REQUIRE.
5468 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5469 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5470 (m4_require): Avoid extra macro calls.
5472 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5474 * tests/torture.at (srcdir): Fix quoting.
5476 Do not pass top_srcdir to configure scripts in testsuite.
5477 * tests/autotest.at (srcdir propagation): Copy install-sh to
5479 (my only test): Drop setting of `top_srcdir'.
5480 * tests/base.at (Input/Output): Likewise.
5481 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5482 config.guess, and config.sub to test source tree.
5483 Drop AC_CONFIG_AUX_DIR setting.
5484 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5485 * tests/torture.at (Substitute a 2000-byte string): Drop
5486 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5487 (Substitute a newline, datarootdir workaround): Likewise.
5488 (Define a newline): Adjust for linenumber changes in configure.ac.
5489 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5491 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5492 if `pwd` contains whitespace.
5494 Quote $abs_top_srcdir in tests.
5495 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
5496 * tests/tools.at (Syntax of the shell scripts): Likewise.
5498 * tests/m4sh.at (LINENO): Quote $0.
5500 Fix testsuite program wrapper for whitespace in `pwd`.
5501 The problem here is that the usual mantra is that command
5502 variables can contain arguments, thus we cannot just escape
5503 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5504 $top_builddir/tests directory early in $PATH, so that the
5505 wrappers are found by their plain name.
5506 * tests/wrapper.as: Put $testdir early in $PATH.
5507 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5509 Proper config.status --file/--header and $srcdir escaping.
5510 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
5511 characters in $ac_file_inputs.
5512 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
5514 * tests/torture.at (datarootdir workaround): Adjust.
5515 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5517 Fix Autotest for whitespace in `pwd`.
5518 * lib/autotest/general.m4 (AT_INIT)
5519 <at_func_create_debugging_script, Driver Loop>:
5520 Quote $at_group_dir.
5521 * tests/autotest.at (whitespace in absolute testdir): New test.
5523 * lib/autom4te.in: Quote @datadir@.
5525 Proper file name escaping in Autoconf programs and Perl modules.
5526 This includes escaping of characters special to the shell
5527 as well as special to Perl, e.g., leading `<' or `>'.
5528 For example, when $file starts with `>', `open ">$file"'
5529 wrongly tries to append to a different file.
5530 * bin/autoconf.as: Fix quoting for autom4te options.
5531 * lib/Autom4te/General.pm (shell_quote): New function, taken
5532 from coreutils, written by Jim Meyering.
5534 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
5536 * bin/autoreconf.in (parse_args): Likewise.
5537 * bin/autoscan.in (main): Likewise.
5538 * bin/autoupdate.in (main): Likewise.
5539 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
5540 * bin/ifnames.in: Likewise, XFile usage fixes.
5541 * tests/tools.at (autom4te and whitespace in file names): Extend
5542 test. Test twice, with special characters allowed on w32, and the
5543 rest. Test leading and trailing whitespace, for `open_quote'.
5544 (autotools and whitespace in file names): New, analogous test.
5545 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5546 by Russ Allbery and Eric Blake.
5549 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5550 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5551 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5552 (update_file, contents): Use it.
5554 * Makefile.am (autom4te-update): Rewrite for git.
5556 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5558 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5560 Fix copyright years.
5561 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5562 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5564 2007-12-04 Eric Blake <ebb9@byu.net>
5566 Manually resync with gnulib, since 'make cvs-update' no longer works.
5567 * build-aux/config.guess: New upstream version.
5568 * build-aux/config.sub: Likewise.
5570 When using older automake, don't downgrade build-aux/texinfo.tex.
5571 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
5572 * doc/Makefile.am (TEXINFO_TEX): Add.
5574 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5576 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5577 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5578 #undef as this runs afoul of our new way of creating config.h.
5579 Problem reported by Jim Meyering in
5580 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
5582 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5584 Fix autom4te for unusual characters in input file names.
5585 * bin/autom4te.in (files_to_options): Quote active characters
5587 * tests/tools.at (autom4te and white space in file names):
5590 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5591 Document that Tru64 awk always splits $0.
5593 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5595 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5596 `#AT_STOP_...' line at the end of each test.
5598 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5600 * lib/autotest/general.m4 (AT_INIT): For awk line number
5601 extraction script, ensure `$at_group' has a defined value
5602 even for the empty set, and properly quote its usage inside
5605 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5607 * doc/autoconf.texi (Shell Functions): New chapter. Document
5608 IRIX sh $0 issue in functions, move content from ...
5609 (Portable Shell): ... here.
5610 (Shell Script Compiler): Note that shell functions are not
5611 totally unportable any more.
5613 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5614 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5616 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5617 extracting the line numbers of the last needed test.
5619 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5621 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5624 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5626 Fix IRIX testsuite debugging failures: $0 in functions.
5627 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5628 Do not use $0 inside a function, as IRIX sh will set that to the
5629 function name rather than the script invocation name.
5631 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5632 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5634 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5635 to extract test scripts.
5636 (AT_INIT): Extract and cache test script line numbers.
5638 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5640 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5641 subsequent fixups; the awk -> here-document conversion trashes
5642 performance too much with AIX sh.
5644 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5646 * tests/local.at: Do not test m4, perl with AT_TESTED.
5648 Diagnose and guard against write errors dealing with config.status.
5649 The general idea is this: all write failures from `configure'
5650 writing `config.status' are indicated by $ac_write_error, which
5651 is only checked at the end. This is safe because config.status
5652 code is not executed before the file is complete. Other write
5653 failures, be they inside config.status, or in sub shell/awk
5654 scripts spawned from configure or config.status, typically need
5655 earlier checking, as their results are used right afterwards.
5656 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5657 before writing config.status, check afterwards.
5658 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5659 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5660 Set `ac_write_error' for write failures to config.status. Barf
5661 upon write failures to temporary files.
5662 Adjust note about closing and reopening the here-document.
5663 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5664 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5665 reopening the here-document.
5666 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5667 Ensure `ac_write_error' does not escape into config.status.
5668 Also, add a couple of code paths not yet exercised in the test
5669 suite: a config file with input from stdin, and a config header
5671 Suggestion for catching write errors by Bruno Haible.
5673 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5675 Avoid error with Tru64 awk and testsuite lines with many words.
5676 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5677 reads the testsuite, set the field separator to an unusual value,
5678 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5679 even splits the input if $i, i>0, was never accessed in the script.
5681 Revert 2007-10-17 change.
5682 * TODO: Multiline args in config files and headers mean something
5683 different and are not fixed, see
5684 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
5685 Report by Stepan Kasal.
5687 * doc/autoconf.texi (Generic Programs): Fix typo.
5689 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5691 AC_*_TOOL does not canonicalize the prefix
5692 * doc/autoconf.texi (Generic Programs): Do not say that
5693 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5695 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5697 Diagnose write errors in config.status instantiations.
5698 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5699 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5701 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5702 Extend test to also check for some write error failures, using...
5703 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
5704 Report by Bruno Haible.
5707 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
5709 (_AT_CHECK): Use less indentation, to save space.
5711 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5713 Add witness macro for @top_build_prefix@ substitution.
5714 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
5715 (_AC_OUTPUT_FILE): Mention it here.
5717 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
5718 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5720 * lib/autotest/general.m4 (at_func_test): Remove.
5721 (AT_INIT): Pre-extract test groups into separate files.
5722 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5723 Remove at-test-source files together with the $at_group_dir.
5724 * tests/autotest.at (Long test source lines): New test.
5726 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5728 Shell functions and variables may share a namespace.
5729 * doc/autoconf.texi (Portable Shell): Mention Solaris sh

5734 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
5737 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5739 * lib/autoconf/status.m4: Fix a couple of comment typos.
5741 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
5743 2007-11-13 Jim Meyering <meyering@redhat.com>
5745 Clean up the rule to create "expr".
5746 * tests/Makefile.am (expr): Don't redirect directly to target.
5747 Redirect just once, not for each echo statement.
5748 Use $@, not literal "expr".
5750 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
5752 Don't worry about preprocessor when testing long long.
5753 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5754 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5755 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5756 These no longer check for preprocessor flaws.
5757 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5758 Do not check for preprocessor flaws.
5760 2007-11-13 Jim Meyering <meyering@redhat.com>
5762 Adapt dependencies, now that a version change doesn't modify configure.ac
5763 * GNUmakefile: Remove "make clean" kludge.
5764 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
5766 Don't redirect directly to target.
5767 Use $@, not literal "version.m4".
5769 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5771 * doc/autoconf.texi (Making testsuite Scripts): Document
5772 ":;{" shorthand as in previous patch.
5774 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
5776 * doc/autoconf.texi (Limitations of Builtins): Document problem
5777 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
5779 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
5780 Use ":;{" shorthand.
5781 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
5783 2007-11-12 Jim Meyering <meyering@redhat.com>
5785 Add more non-srcdir build support.
5786 * GNUmakefile (dummy): Split a long line.
5787 Add -v option to autoreconf invocation.
5789 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5790 * GNUmakefile (dummy): Remove INSTALL.
5792 Remove racy commands to build scripts in bin/ and tests/.
5793 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5794 are guaranteed to be built, remove the rules that tried to build
5795 them. Before, with a parallel build, these rules could lead to
5796 two processes writing tests/wrapper.in concurrently.
5798 Build in man/ only *after* building in bin/ and tests/.
5799 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5800 in both bin/ and tests/.
5802 Accommodate non-srcdir build-from-checkout.
5803 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5804 Use git's --git-dir=$srcdir/.git option.
5805 Add quotes, in case tarball_version_file contains shell meta-characters.
5806 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5807 * configure.ac: Pass "." to git-version-gen.
5809 Avoid spurious test failures due to version skew.
5810 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
5812 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5814 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
5815 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):

5817 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
5818 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):

5837 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5839 Ignore configure --help* errors due to LINENO-impaired shells.
5840 * tests/torture.at (Configuring subdirectories, Deep Package):
5841 In the --help* tests in read-only trees, make `.' temporarily
5842 writable again for the `stderr' file, and ignore errors due to
5843 the attempt to write configure.lineno.
5844 Report by Patrick Welche.
5846 2007-11-10 Jim Meyering <meyering@redhat.com>
5848 Generate package.m4 in build-dir, not srcdir.
5849 * tests/Makefile.am (package.m4): Adjust target.
5850 Don't redirect directly to $@.
5851 (CLEANFILES): Add package.m4.
5852 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5854 When running $(AUTOTEST), search "." before searching $(srcdir).
5856 Avoid a race condition that would make parallel "distclean" fail.
5857 * tests/Makefile.am (distclean-generic): Replace the default,
5858 automake-provided rule with an identical one, but with an additional
5859 dependency on distclean-local. Simply adding the dependency would
5860 cause automake not to emit the rule at all.
5861 * BUGS: Building with -jN works, now.
5863 Distribute git-version-gen.
5864 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5865 since GNUmakefile is distributed, and requires it for dist* rules.
5867 Remove two more generated files from version control.
5868 * INSTALL: Remove generated file.
5869 * lib/autoscan/autoscan.list: Remove generated file.
5871 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5873 * GNUmakefile (PATH): Remove stray apostrophes; they become
5874 part of PATH, which isn't wanted here.
5876 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5878 New config files output variable `top_build_prefix'.
5879 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5881 * doc/autoconf.texi (Preset Output Variables): Document it.
5883 Report by Bob Friesenhahn.
5885 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5886 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5887 function, to parametrize arithmetic with expr vs. the shell.
5888 Use it where possible.
5889 Suggestion by Benoit Sigoure.
5891 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
5893 Adjust the documentation of autotest WRT atlocal.
5894 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5895 when using Automake, to write a rule to produce atlocal, since it's
5896 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5897 distributed, not atconfig.in.

5920 Adjust the build procedure so "make check" works reliably.
5921 * README-hacking: Include an extra step between "make" and
5922 "make check" to ensure that the latter passes.
5924 Use just-built tools, when possible.

5998 Make inter-release --version output more useful.
6000 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6001 which indicates that it is built using the 19th change set
6002 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6003 is a prefix of the commit SHA1.
6004 * build-aux/git-version-gen: New file.

6014 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6015 git-version-gen doesn't match $(VERSION), but only for dist targets.

7314 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7315 works but the latter doesn't, then it's a valid type.

7450 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
7452 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
7453 input from /dev/null in awk test, so even Solaris /usr/bin/awk
7454 will not wait for input with a script containing only a BEGIN

7488 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7490 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7491 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7492 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7493 substitution will still be done by the special code.

7508 Test all 8 bit non-NUL characters.
7509 Report against Automake by Patrick Welche.
7511 2007-01-15 Stepan Kasal <kasal@ucw.cz>
7513 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
7515 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7517 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7518 early on the reader side, drop stderr of the input to avoid
7519 `broken pipe' error output; this may happen even with shell
7520 builtin `echo' of some bash versions. Reports by Ian Macdonald
7521 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7523 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7525 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
7526 separate items of `ac_user_opts', to avoid long lines.
7527 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
7529 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7535 Fix some wording problems noted by Paolo Bonzini in:
7536 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7537 * doc/autoconf.texi (Signed Overflow Examples): Give more
7538 discussion about the allow_superuser_privileges example,
7539 and change it a bit to make things clearer.
7540 (Optimization and Wraparound): Clarify whether the compiler
7541 will generate an infinite loop for the example derived from
7542 Autoconf's mktime test.
7543 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7544 Also, clarify unsigned multiplication overflow.
7546 2007-01-04 Eric Blake <ebb9@byu.net>
7548 * bin/Makefile.am (RELEASE_YEAR): New macro.
7549 (edit): Use it to supply correct copyright year to scripts.
7550 * bin/autoconf.as (version): Use it.
7551 * bin/autoheader.in ($version): Likewise.
7552 * bin/autom4te.in ($version): Likewise.
7553 * bin/autoreconf.in ($version): Likewise.
7554 * bin/autoscan.in ($version): Likewise.
7555 * bin/autoupdate.in ($version): Likewise.
7556 * bin/ifnames.in ($version): Likewise.
7558 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7560 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7561 feedback. The most important changes document what happens when
7562 you convert an out-of-range value to a signed integer type, and
7563 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7566 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7567 rewrite, taking notions from the recent discussion on the gcc and
7568 autoconf mailing lists; please see
7569 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7570 and follow the many links.
7571 (Integer Overflow Basics, Signed Overflow Examples):
7572 (Optimization and Wraparound, Signed Overflow Advice):
7573 (Signed Integer Division): New sections.
7575 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7577 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7578 preprocessor macro arguments in traced name.
7579 * doc/autoconf.texi (Defining symbols): Document longstanding
7580 support for AC_DEFINE-ing macros with arguments, and document
7581 behavior when the same variable has multiple AC_DEFINEs.
7582 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7583 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7584 macros directly, giving much shorter and simpler code.
7586 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7588 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7589 space before "$ac_configure_args" to prevent a 'config.status
7590 --recheck' failure if ac_configure_args doesn't contain a leading
7591 space. This works around a problem with the XEmacs configure.ac,
7592 which uses the (undocumented) ac_configure_args variable
7593 inconsistently with Autoconf.
7595 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7597 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7598 Include <limits.h>, and use its INT_MAX to rewrite the
7599 j loop so that it does not overflow 'int'. Problem reported by
7601 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7602 Play it safe by shifting left by 1 rather than multiplying by 2,
7603 as GCC is less likely to optimize this away when the value
7604 is signed (when it assumes overflow leads to undefined behavior).
7605 Also, don't assume time_t uses two's complement.
7607 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7609 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7610 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7611 dumps core on it. Report by Tim Rice.
7613 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7615 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7616 --disable-option-checking to --help output even when
7617 AC_PRESERVE_HELP_ORDER is not used.
7618 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7619 --with argument, rather than argument with [-.] replaced by
7621 * NEWS: Fix typo in previous change; the news was in the
7624 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7626 * NEWS: Warnings are now generated by default for unknown
7627 --enable-* and --with-* options.
7628 * doc/autoconf.texi (Option Checking): Renamed from
7629 (Configure Option Checking). Tighten up the wording a bit.
7630 (External Software, Package Options): Cross-reference to Option
7631 Checking, and use this to shorten our section.
7632 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7633 "$x" to test "x$foo" != x.
7634 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7635 Don't warn if $enable_option_checking is "no".
7636 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7637 ac_unrecognized_opts to the empty string.
7638 Don't echo the unrecognized opts, as this might mishandle
7639 backslashes or leading -.
7640 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7641 usage next to the other --disable-FEATURE options in the
7644 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7646 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7647 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7648 Print warning for unrecognized --with and --enable options
7649 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7650 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7651 Disable option checking when subdirs are configured.
7652 (AC_OUTPUT): If warnings are enabled, print warning about
7653 unrecognized --with and --enable options at the end of
7654 the configure output (as well as at the beginning).
7655 * doc/autoconf.texi (Option Checking): New node.
7656 Document new option warning functionality.
7658 2006-12-16 Eric Blake <ebb9@byu.net>
7660 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7661 * NEWS: Start news for current version.
7663 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7665 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7666 Define HAVE_GETMNTENT to 1, not to the empty string.
7667 Problem originally reported by Jochen Friedrich in
7668 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7670 This change prompted by a problem report by Andrey Simonenko in
7671 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7672 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7673 object-like macros only, in the traditional portable character
7675 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7676 Warn about attempts to define things that are not identifiers.
7677 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7678 awful hack that AC_DEFINEd macro names containing parentheses.
7680 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7682 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7683 too drastic, even if Texinfo in theory requires it for info mode.
7685 (config.status Invocation): Renamed back from Recreating a
7687 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7688 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7690 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7692 * NEWS: Version 2.61a.
7694 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7695 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7697 * NEWS: Document changes with echo and printf, and the lack
7698 of limits on the total size of multi-line values of substituted
7699 variables, and the AC_FUNC_FSEEKO fix.
7701 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7703 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7704 Writing configure.ac.
7705 (Autoconf Input Layout): Renamed from configure.ac Layout.
7706 (Recreating a Configuration): Renamed from config.status Invocation.
7707 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7708 (acconfig Header): Renamed from acconfig.h.
7709 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7710 (Writing Testsuites): Renamed from Writing testsuite.at.
7711 (Autom4te Cache): Renamed from autom4te.cache.
7713 * BUGS: Remove mention of VPATH problem, since it's now documented
7714 not to be a bug in the Autoconf build procedure itself, but rather
7715 a problem with the proprietary `make' programs.
7717 * doc/autoconf.texi (Build Directories): Add a cross reference
7720 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7721 * doc/standards.texi: Sync from gnulib.
7723 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7724 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7725 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7726 generated automatically.
7728 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7730 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7731 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7732 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7734 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7736 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7737 `CEOF$ac_eof' special marker, the awk script cannot contain a
7738 line matching `^CEOF', so this is not needed any more.
7739 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7740 special marker in the test.
7742 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7744 * tests/tools.at (autom4te preselections): Use `find -newer';
7745 remove one of the sleeps.
7747 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7748 more readable, using ...
7749 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7751 * doc/autoconf.texi (autoheader Invocation): Do not double-
7752 quote the parameter of `AH_BOTTOM' in the example.
7754 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7756 * doc/autoconf.texi (Configuration Headers): Remove the
7757 example with multiple input files.
7758 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7759 multiple input files.
7761 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7763 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7764 creating the awk substitution script, handle one input line at a
7765 time, so that the maximum length of a substituted (multi-line)
7766 value is not limited by the size of the sed pattern space.
7767 The trade-off is a slightly repetitive sed script.
7768 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7769 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7770 * tests/torture.at (Substitute a 2000-byte string): Increase the
7771 test with several long lines, they should not be caught by sed
7774 * tests/tools.at (autom4te preselections): New test, to flag
7775 entries missing from autom4te.cfg.
7776 Report by David Byron <dbyron@hheld.com>.
7778 * tests/torture.at (Substitute a 2000-byte string): Actually use
7779 AC_PROG_AWK, so the last change works as intended.
7780 (Substitute and define special characters): Likewise.
7781 (Substitute a newline): Likewise.
7783 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7784 instead of `awk' consistently.
7785 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7786 * tests/torture.at (Torturing config.status): Test both the
7787 result of AC_PROG_AWK and plain awk.
7788 (Substitute a 2000-byte string): Likewise.
7789 (Substitute and define special characters): Likewise.
7790 (Substitute a newline): Likewise.
7792 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7794 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7795 can be assigned to a function pointer. Problem reported by
7796 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7797 part of a patch by Ralf Wildenhues in that same bug report.
7799 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7801 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7802 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7804 2006-12-01 Eric Blake <ebb9@byu.net>
7806 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7807 cross-compiling from cygwin to mingw.
7808 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7809 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7810 to lib/autoconf/c.m4.
7812 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7814 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7815 string for more reliable failure. Wrap the entire test that
7816 causes the broken Solaris printf to dump core, in a subshell,
7817 so the segmentation fault message is reliably suppressed.
7818 Fix shell expansion errors by using /usr/ucb/echo always;
7819 avoid an error on systems without it by another subshell.
7820 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7821 subshell-$as_echo to `as_echo', for better error message.
7823 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7825 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7826 `BASH_SOURCE' contain a newline, set them to empty, as they may
7829 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7831 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7832 years and is too hard to maintain now. The last straw was
7833 reported by Jerker Baeck in
7834 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7835 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7836 * doc/autoconf.texi (Particular Functions): Move
7837 AC_FUNC_SETVBUF_REVERSED from here...
7838 (Obsolete Macros): ... to here. Say that it does nothing now.
7839 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7840 Turn into (almost) a no-op.
7842 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7844 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.

7856 @VAR1@VAR2 has unspecified behavior. Problem reported by
7858 * NEWS: Mention this.
7860 * Makefile.am: Put only a single '#' into the copyright notice,
7861 so that it's also present in the output file. Standardize wording
7862 in makefile copyright notices to match GNU coding standards.

7876 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7878 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7879 in the sed script that mangles the awk script: delete up to the
7880 first exclamation mark only.
7881 * tests/torture.at (Substitute and define special characters):
7884 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7886 Rewrite config files generation: avoid quadratic growth in
7887 the number of substituted variables by using awk instead of sed
7888 for the bulk of the substitutions.
7889 * NEWS: Mention this.
7890 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7891 forbidden in the output (and thus input) file.
7892 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7893 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7894 generate just one large awk script for substitutions,
7895 eliminating much of the earlier complexity, while adding some
7896 new complexity. Only expand the substitution templates at
7897 configure time, for smaller configure script size. If
7898 _AC_SUBST_FILES are used, test 'awk' for working getline support
7899 at config.status time. If absent, interpolate through the
7900 shell. The awk script was written with much help
7901 from Paolo Bonzini and Paul Eggert.
7902 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7903 (_AC_SED_FRAG_NUM): Likewise.
7904 (_AC_SUBST_CMDS): Renamed from...
7905 (_AC_SED_CMDS): ...this.
7906 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7907 * tests/torture.at (Substitute a 2000-byte string): Also
7908 substitute a line with 1000 words, and a variable with several
7910 (Substitute and define special characters): Test awk special
7911 characters, and put substitution input strings `@foo@' in the
7912 output, to test that no recursion happens; test several other
7913 combinations from Paolo Bonzini.
7915 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7917 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7918 that replaced echo with AS_ECHO where this wasn't necessary.
7919 Problem reportd by Ralf Wildenhues.
7920 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7921 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7922 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7924 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7926 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7928 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7930 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7931 that traditional Awk lacks 3-arg "split". It has it.
7932 Mention that FS must be a single character, and a few other
7933 99-byte limits of traditional Awk.
7934 Mention that if (i in a) doesn't work with traditional Awk.
7936 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
7938 * tests/autotest.at (BSx641-newline in command):

7940 (Newline-CODE-BS-newline in command):
7941 (Single-quote-BS-newline in command):
7942 (Single-quote-newline-BS-newline in command):
7943 Use printf '%s\n' instead of echo, for portability to hosts
7944 where echo interprets backslashes. This will break on hosts
7945 that lack printf, but for now let's assume all such hosts
7946 are dead (if not, we should get reports of test failures).
7948 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7950 'echo' has some portability problems, when given a first argument
7951 with a leading '-', or when given any argument containing '\'.
7952 Avoid using 'echo' in these cases.
7953 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

7956 * lib/autotest/general.m4 (AT_INIT): Likewise.
7957 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
7958 argument might be unportable.

7977 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
7978 * bin/autoconf.as: Redo verbose flag implementation, as the old
7979 scheme wouldn't work with AS_ECHO.
7980 * lib/autotest/general.m4 (AT_INIT): Likewise.
7981 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7982 Don't use ECHO_T, since ECHO_N is now reliable.
7983 * lib/autotest/general.m4 (AT_INIT): Likewise.
7984 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7985 rather than using a here-document to put the script into a file.
7986 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7988 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7989 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7990 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7991 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7992 * lib/autotest/general.m4 (AT_SETUP): Likewise.
7993 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
7994 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7995 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
7996 operand, as AS_ECHO requires. Avoid double file name expansion.
7997 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7998 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7999 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8000 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8001 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8002 Double-quote strings that would otherwise contain M4 comments.
8003 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8005 * configure.ac (AC_INIT): Bump to 2.61a.
8008 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8012 * configure.ac (AC_INIT): Bump to 2.61.
8015 * tests/autotest.at (Macro with backslash in a test title):
8016 Comment out for now, as this tests neither fails nor passes
8017 reliably. Problem reported by Ralf Wildenhues.
8019 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8021 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8022 in previous change, which caused test failures.

8096 benefit of platforms like Solaris+GCC where it is common to have a
8097 non-working g++ installation.

8100 and Joel E. Denny <jdenny@ces.clemson.edu>
8101 and Paul Eggert <eggert@cs.ucla.edu>
8103 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
8104 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
8107 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8109 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8110 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
8111 Imported from a similar patch to gnulib by Bruno Haible.
8113 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8115 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

8132 and Stepan Kasal <kasal@ucw.cz>
8134 Handle special characters in test case titles correctly.
8135 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8137 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8138 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8139 argument. Extend to check titles printed by ./micro-suite and
8140 ./micro-suite -l and the title in micro-suite.log.
8141 (Backquote in a test title,
8142 Single-quote in a test title,
8143 Double-quote in a test title): Don't expect failure anymore.
8144 (Backslash in a test title): Put a non-whitespace character after the
8145 backslash so that Bourne shells might actually see it as an escape
8147 (Brackets in a test title,
8148 Pound in a test title,
8149 Comma in a test title,
8150 Quoted Macro in a test title,

8154 Macro with double-quote in a test title,
8155 Macro with backslash in a test title): New tests expected to fail.
8156 * tests/torture.at (#define header templates): M4-quote this title in
8157 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8158 The visible effect was a stray [] in the testsuite output.
8160 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8162 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8163 `trap ... 0' inside a function, for AIX sh.
8165 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8167 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8168 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8169 5363) simply issues a warning when dividing by zero at compile
8170 time. Problem reported by Elias Pipping.
8172 2006-10-26 Eric Blake <ebb9@byu.net>
8175 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8176 show effect on macros that expand with commas.

8201 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8203 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8204 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8205 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8206 reported by Nelson H. F. Beebe for Coreutils 6.4.
8208 * tests/tools.at (autoconf --trace: user macros): Remove test
8209 for tracing multiline macros, since m4 1.4.7a uses a different
8210 way to number lines. Problem reported by Ralf Wildenhues.
8212 2006-10-24 Stepan Kasal <kasal@ucw.cz>
8214 * bin/autom4te.in (handle_m4): Do not redirect stdin to
8215 /dev/null since the heuristics for interactive behaviour was

8240 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8241 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

8272 looking for special shell characters.
8273 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
8274 macro defined by AS_VAR_PUSHDEF before passing it as a

8286 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8288 (Imported from Automake.)
8289 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8290 which incorrectly sets the mode of an existing destination
8291 directory. In some cases the unpatched install-sh could do the
8292 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8293 system. We hope this is rare in practice, but it's clearly worth
8294 fixing. Problem reported by Alex Unleashed in
8295 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8296 Also, don't bother to check for -m bugs unless we're using -m;
8297 suggested by Stepan Kasal.

8329 (\lquoteexpand, \quoteexpand): new defs.
8330 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
8331 (\code): must use new \...Char values, since now ` is active.

8341 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
8343 2006-10-13 Stepan Kasal <kasal@ucw.cz>
8345 * doc/autoconf.texi (Autoheader Macros): Warn that the text
8346 added to the template can get mangled.
8348 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8350 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8351 include the default headers, and redefine obstack_chunk_alloc
8352 and obstack_chunk_free. Fixes false failure with glibc.

8366 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8368 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
8369 the NonStop platform.
8370 * doc/autoconf.texi (Posix Variants): Likewise.
8371 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8373 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8374 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8375 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8376 Use a better substitute, by inspecting the output of "ls"
8377 rather than just using ":".
8378 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8379 rather than AS_EXECUTABLE_P, since we needn't worry about
8380 non-regular files here.
8382 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8383 due to configuration hassles with this. See Tonya Underwood's report
8384 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
8385 * doc/autoconf.texi (Special Shell Variables): Likewise.

8395 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
8396 initialization which is not inherited through the environment
8397 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8398 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8407 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8408 comment about ac_cpp_err; it was incorrect, and anyway
8409 ac_cpp_err is being removed below.
8410 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8411 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8412 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8414 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8415 with werror_flag and conftest.err and so forth. This is more
8416 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8417 and anyway the user shouldn't normally want to see this gorp logged.
8418 Problem reported by Ralf Wildenhues.
8419 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8420 empty, not 'no', since the rest of the code uses 'test -z'.
8422 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
8424 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8425 Use a single call to AC_DO_TOKENS rather than multiple, for
8427 (_AC_LINK_IFELSE): Test that resulting file is executable.
8428 Problem reported by mwoehlke in
8429 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8431 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8432 than creating a file to use with test -x; this is much faster.
8434 2006-10-02 Bruno Haible <bruno@clisp.org>
8436 * lib/autom4te.in (Automake-preselections): Add
8437 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8439 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8441 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

8444 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
8446 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
8447 fseeko testing program twice; just use the earlier result.
8448 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8449 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8450 still doesn't let the program compile.
8451 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8454 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8455 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8456 include it, without including anything else.

8459 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8463 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
8464 `error.h', and include it, for a `error_at_line' prototype.
8465 Use a nonempty format string in the link test.
8466 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
8467 for a declaration of wait3.

8472 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
8473 can apply to constants too, and that it checks for macro defns.
8474 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
8475 and simply cast the identifier to void. This handles structure
8476 values. Problem reported by Ralf Wildenhues.

8566 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
8567 for the existence of the directory at configure-time. That's
8568 too late, anyway. Problem reported by Stefan Seefeld.
8570 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
8571 7.1.4 /usr/bin/posix/sh described by Tim Rice in
8572 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.

8576 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
8577 works with GNU M4 1.4.3 again; make the normalized form

8687 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
8689 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
8690 didn't work if some values were cached but not others. Test for
8691 broken lex libraries like native ia64-hp-hpux11.22; see
8692 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8693 work around the problem by preferring an empty LEXLIB to -lfl or
8694 -ll. Let the user set LEXLIB='' to indicate no library needed.
8696 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

8816 longer supported by Sun.
8818 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
8820 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
8821 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8822 -Wundef -Werror". Problem reported by David Fang in
8823 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8845 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
8846 problems with arg script text that doesn't end in newline, and
8847 with '-e a...'. Problems reported by Ralf Wildenhues.
8849 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
8851 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
8852 check for libXt by a check for libX11.

8883 less skeptical about "volatile", after discussion with
8884 Bruno Haible on bug-gnulib.

8886 leading white space from text. From Bruno Haible.
8888 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
8890 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
8891 compiler complains about it, even if things works after the
8892 complaint. Problem reported by Peter O'Gorman.
8894 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
8895 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
8896 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
8898 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
8900 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
8901 after -R regardless of host. Patrick Welche reports that this

8912 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
8913 under AC_C_VOLATILE.
8914 (Volatile Objects): Be a little less skeptical about what
8915 "volatile" means. Derived from thoughts by Ben Pfaff in
8916 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
8918 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8922 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
8924 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8925 more globally, since the 2006-06-30 patch didn't suffice. Problem
8926 reported by Keith Marshall. Also, don't bother with builddir2,
8927 since it shouldn't be needed any more.
8929 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

8948 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8950 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8951 Require that long long int be at least 64 bits wide. C99 requires
8952 this and enough programs depend on it so we should check for it.
8953 Bruno Haible reports in
8954 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8955 that long long int is 32 bits wide with some nonstandard compilers.
8956 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
8958 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
8960 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8961 to a nonexistent file, so that we don't have to worry about
8962 a local site configuration that doesn't use /usr/local.
8963 Problem reported by Keith Marshall in
8964 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8966 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8968 * doc/autoconf.texi: Be more consistent about using @acronym with
8969 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8970 quite right (it talked about "OSF/Tru64", even though the
8971 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8972 and it even mentioned "OSF 4"!) and at this point there's little
8973 reason to talk about OSF any more, since it died in 1994.
8974 (Specific Compiler Characteristics): Simplify example of
8975 negative-size array.
8976 (File Descriptors): Reorder to make the text flow better.
8977 Remove joke about "appreciate the various levels"; I didn't get it.
8978 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8979 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8980 (File Descriptors, Limitations of Usual Tools):
8981 Tone down the advice against renaming or removing open files.
8982 (Limitations of Usual Tools): Add a new section, on 'rm'.
8984 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8986 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8987 -lXt in LIBS, idea from Karsten Hopp; this was due since
8990 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8991 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8992 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8993 (which belong to Xt, not X itself). See Debian bug 327655.
8995 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8997 * configure.ac (AC_INIT): Bump to 2.60a.

9017 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9019 * doc/autoconf.texi (Changed Directory Variables): New node,
9020 to document the whole `datarootdir' business a bit better.
9022 * tests/torture.at (datarootdir workaround): Extend test.
9023 Prompted by report by Alexandre Julliard.
9025 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9027 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9028 when using default mode of IBM C 6 for AIX. Problem and two-line
9029 fix reported by Larry Jones.
9031 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9033 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9034 about literal '${datarootdir}' if a definition is found in the
9037 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9039 * NEWS: Use "M4" rather than "m4" when appropriate.
9040 Problem reported by Eric Blake.
9041 * doc/autoconf.texi: Likewise.
9042 Use @acronym around BSD, GCC, and GNU when appropriate.
9043 (Why GNU M4): Renamed from "Why GNU m4".
9044 (Redefined M4 Macros): Mention that Posix
9045 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9046 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9049 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9051 * bin/autom4te.in (handle_output): Do not forbid the empty
9053 * tests/tools.at (autoconf: the empty token): New test.
9055 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9057 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9058 calls, so that we do not care whether they are LIFO or FIFO;
9059 in the m4_wrap, do not check which diversion is the topmost
9060 one, just check that the stack is balanced at the end.
9061 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9062 base diversion forever--pop the previous diversion before
9063 opening the new one; consequently, remove the m4_wrap call.
9064 * lib/autotest/general.m4 (AT_INIT): Likewise.
9065 * tests/m4sugar.at: Do not use
9066 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

9069 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9071 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9072 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9073 Rework example of m4wrap token-pasting trouble so that it doesn't
9074 care whether it's LIFO or FIFO.
9075 Fix some "contrary to"s that are awkward in English.
9077 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9079 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9080 to `yes' instead of `int$1_t' if the type is found, for more
9081 consistent configure output (where $1 is the number of bits).
9082 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9083 Suggested by Bruno Haible.
9085 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9086 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9087 with system headers. Report by Bruno Haible.
9089 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9091 * config/config.guess, config/config.sub: Sync from upstream.
9093 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9094 in order to avoid picking up an older installed frozen m4sh.m4f.
9095 Besides an outdated shell startup, this could have been created
9096 by an earlier M4 version with incompatible frozen file format.
9098 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9100 * README: Recommend m4 1.4.4 instead of 1.4.3..
9101 * doc/autoconf.texi: Likewise.
9102 (Special Chars in Names): Say that $(.FOO) is portable, as
9103 suggested by Stepan Kasal.
9104 (Installation Directory Variables, Build Directories):
9105 (Automatic Remaking, Subdirectories, Fortran Compiler):
9106 (Making testsuite Scripts, Defining Directories):
9107 Quote variable usages better.
9108 (Making testsuite Scripts): Add clean-local rule to makefile
9109 snippet, by Eric Blake.
9110 (Installation Directory Variables): Fix table item font.
9111 Reword slightly to clarify. Generalize advice about
9112 not using special characters to include all file-related
9113 vars, not just VPATH.
9114 (Special Chars in Variables): Warn about special characters in
9116 (Assignments): Clarify default-value example as suggested by
9118 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9119 (Special Shell Variables): Note leading ./ or ../, as suggested
9121 (Limitations of Builtins): Under cd, warn about CDPATH.
9122 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9125 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9127 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9128 `@var', for texi2html.
9129 (Systemology): Some more word wrapping, for DVI output.
9130 (autom4te Invocation): The short option for `--melt' is `-M',
9133 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9135 * doc/autoconf.texi: More formatting and English tweaks,
9136 many suggested by Ralf Wildenhues.
9137 Reword to avoid "@code{...}'s" and the like, since it's ugly
9138 with Emacs info mode. discontents -> woes.
9139 Put a few "will"s back. time stamp -> timestamp.
9140 side-effect -> side effect.
9142 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9144 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9145 Warn about $@ not persisting. Problem reported by Julien Danjou in
9146 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9147 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9148 Mention other special chars, too.
9150 2006-06-14 Eric Blake <ebb9@byu.net>
9152 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9154 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9156 * doc/autoconf.texi: Some systematic minor improvements, as
9157 follows. Use "makefile" when talking about makefiles
9158 generally (which might be named "makefile" or "Makefile" or even
9159 "foo.mk"), "Makefile" when talking about a specific makefile
9160 called "Makefile". This unclutters the text from weird quotes
9161 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9162 values" rather than "@var{foo}s" and similar constructs containing
9163 "}s". Use "Make rules" rather than "Makefile rules". Minor
9164 English-language improvements. Change the prefix "sub-" to "sub"
9166 Put blank lines around examples more consistently.
9167 Avoid "rather" and "very" as intensifiers.
9168 Avoid "will" as an auxiliary.
9169 (Limitations of Make): Split this node into....
9170 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9171 (Leading _ in Macro Names, Backslash-Newline-Newline):
9172 (Backslash-Newline Comments, Long Lines in Makefiles):
9173 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9174 (obj/ and Make, make -k Status, VPATH and Make):
9175 (VPATH and Double-colon, $< in Explicit Rules):
9176 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9177 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9178 New nodes, resulting from splitup of Limitations of Make.
9179 All cross-references changed. Raise the top node from
9180 a section to a chapter, and all subnodes accordingly.
9181 Redo the introductory wording to match the new organization.
9182 (Installation Directory Variables): Use an example that is
9183 closer to what Autoconf actually does. Mention that VPATH's
9184 value should not contain metacharacters or white space.
9185 (Fortran Compiler): Fix a VPATH bug in an example.
9186 (Leading _ in Macro Names): Mention that this problem is no longer
9187 of practical concern.
9188 (VPATH and Make): Reword the advice to make it clearer
9189 that Autoconf and Automake support VPATH in non-GNU make, but
9190 many packages have bugs in this area.
9191 ($< in Explicit Rules): Refer to Build Directories rather
9192 than using a (non-VPATH-safe) example.
9193 (Automatic Rule Rewriting): Mention the sort of disaster that
9194 can ensue with Solaris-style rule rewriting with VPATH.
9196 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9198 * doc/install.texi (Compilers and Options): Weaken the
9199 suggestion to use GNU make for VPATH builds.
9201 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9202 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9204 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9205 in regular expression.
9207 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9209 * doc/autoconf.texi (Installation Directory Variables):
9210 Drop extra @samp from `@table @samp' item.
9211 (Limitations of Usual Tools): Comment fix.
9212 Do not nest @samp just to point to other table items.
9213 (Writing testsuite.at) <AT_CHECK>: The second argument to
9214 `@dvar' is already @samp'ed.
9215 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9216 do not use @var in the second argument.
9218 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9220 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9221 $as_shell.exe too. Problem reported by Andreas Buening in
9222 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.

9227 `unused variable' compiler warning, for `-Wall -Werror'.
9228 Reported by Jaap Haitsma in
9229 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9231 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9233 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9234 case the compiler dumps core. Problem reported for
9235 OpenServer 5.0.7 by Tim Rice in
9236 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9237 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9240 2006-06-06 Tim Rice <tim@multitalents.net>.
9242 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9243 "ERROR" only shows up in "make check" output if there is an

9248 * tests/tools.at (automatically allowed tokens): Fix typo.
9250 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9252 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.

9267 * config/texinfo.tex: Sync from upstream.
9269 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9270 seen, invoke libtoolize with `--ltdl' argument.
9271 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9273 Suggested by Eric Blake.

9287 * doc/autoconf.texi: Modernize some of the references to Solaris.
9289 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9291 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9292 message issued by AC_REQUIRE.
9293 * tests/m4sugar.at: Check m4_require's error message.
9294 * tests/base.at: Check AC_REQUIRE's error message.
9295 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9297 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9299 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9300 `expout' as the last parameter.
9301 * tests/tools.at: Adapt to the above change.
9303 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9305 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9306 information about race-free implementations of mkdir.
9308 2006-06-04 Eric Blake <ebb9@byu.net>
9310 * bin/autoreconf.in (help): Document M4 environment variable.
9311 * bin/autoconf.as (Usage): Likewise.
9312 * bin/autom4te.in (help): Likewise.
9313 * doc/autoconf.texi (autom4te Invocation): Likewise.
9315 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9317 * NEWS: GNU make now recommended for VPATH builds.
9318 Mention that some macros are now documented to be obsolescent.
9319 * doc/autoconf.texi:
9320 Prefer "current" to "modern" to describe
9321 currently-used (albeit perhaps old-fashioned) hosts.
9322 Mention which ancient features no longer need to be worried about.
9323 setgid -> set-group-ID
9324 setuid -> set-user-ID (these are the Posix terms)
9325 Fix some misuses of "only".
9326 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9327 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9328 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
9329 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
9330 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
9331 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
9332 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
9333 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
9334 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
9335 Mention that these macros are obsolescent.
9336 (Installation Directory Variables): shall -> should
9337 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9338 Mention that it's now safe to use 3 and 4.
9339 (Limitations of Usual Tools): cp -r is now specified by Posix.
9340 Omit longwinded and obsolescent discussion of cp -f.
9341 Modernize discussion of expr, ls.
9342 (Limitations of Make): Modernize discussion of VPATH builds.
9343 Mention $? as a workaround in some cases.
9344 * doc/install.texi (Basic Installation):
9345 Mention "./configure; make; make install" first. Be more
9346 specific about why this file is generic. Remove unnecessary
9347 parens. Remove misleading "only". Remove obsolete advice
9348 about csh. Don't say "configure" takes awhile; say it
9349 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9350 and CC=c99 rather than CC=c89, as these are blessed by current
9351 Posix. Recommend GNU make if doing a VPATH build.
9353 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9355 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9356 examples involving shell prompts.
9358 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9359 and Paul Eggert <eggert@cs.ucla.edu>
9361 * doc/autoconf.texi (Here-Documents): Add details about the
9362 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9363 use "here-documents" instead of "here documents".
9365 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9367 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
9369 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
9371 * doc/autoconf.texi (File System Conventions): Warn about ":"
9372 anywhere in directory names.
9374 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9376 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9377 about quoting the case statement, just in case.
9378 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9379 was fixed in ksh93g; reported by Ralf Wildenhues.
9381 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9383 * doc/autoconf.texi (System Services): Do not document
9384 overriding EXEEXT via ac_cv_exeext=ext.
9385 (Particular Programs) <AC_PROG_MKDIR_P>:
9386 Document that ${MKDIR_P} understands --.
9387 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
9390 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9392 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
9393 argument with leading hyphen. Problem reported by Paul Eggert.
9395 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9397 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9398 about quoting ac_try: quote all of it, if any of it seems suspicious.
9399 This means we don't have to worry about ${ or sed any more.
9400 Also, double-quote the case statement, to work around misuses via
9401 underquoting as reported by Ralf Wildenhues in
9402 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9403 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9404 undocumented and dangerous macro.
9405 Problem reported by Ralf Wildenhues in
9406 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
9408 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9410 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
9411 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
9412 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
9414 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9416 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9417 since evidently some packages rely on the old, broken behavior.
9418 Problem reported by Ralf Wildenhues in
9419 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9420 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9421 pre-2006-05-26 definitions, but leave in the comments that
9422 these macros are dangerous and should not be used.
9423 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9424 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9425 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9426 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9427 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9429 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9431 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9432 the use of 'tr', since this is our only use of 'tr'.
9434 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9435 and Paul Eggert <eggert@cs.ucla.edu>
9437 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9438 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9440 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9442 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9443 the output file in the `${datarootdir}' test.
9445 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9446 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9448 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9449 mention of `datarootdir' in the input file(s), but literal
9450 `${datarootdir}' in the output file, and we haven't warned yet,
9451 then warn as well: the user may have (erroneously) used
9452 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9453 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9454 * tests/torture.at (datarootdir workaround): Extend this test.
9457 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9458 and Paul Eggert <eggert@cs.ucla.edu>
9460 * doc/autoconf.texi (autoheader Invocation): The first argument to
9461 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9462 alternatives and clear up the language a bit.
9464 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9466 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9467 ac_config_guess, ac_config_sub, ac_configure.
9468 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9469 Fix typo that prevented an unnecessary space from being removed.
9470 Problems reported by Ralf Wildenhues in:
9471 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9473 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9475 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9476 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9477 Don't use the term "thread-safe" to talk about mkdir race
9478 conditions, since the problem is more a process than a thread
9479 issue. Problem reported by Stepan Kasal in:
9480 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9481 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9482 the test for 'install' more closely. Look at MKDIR_P first.
9483 Look in the PATH, and at /opt/sfw/bin.
9484 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9485 Don't bother to try mkdir -p, since we already check mkdir --version;
9486 just look at the version number. (There's no easy way to check
9487 for race-free implementations.)
9488 * tests/tools.at (autoconf: subdirectories): Adjust to above
9489 changes, since MKDIR_P now might end in "/mkdir -p".
9491 * doc/autoconf.texi (autoheader Invocation): Mention that the
9492 first arg of AC_DEFINE_UNQUOTED must be a literal.
9493 Problem reported by Ben Pfaff in
9494 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9496 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9497 * doc/autoconf.texi (Special Chars in Variables): New section.
9498 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9499 (Installation Directory Variables): Quote $(datadir) better.
9500 (Limitations of Builtins): Describe some of eval's trickiness.
9502 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9503 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9504 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9505 in front of every arg, not just trailing args. Quote apostrophes.
9506 (_AC_EVAL_ECHO): New macro.
9507 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9508 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9510 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9511 exposed by quoting of eval argument. Put the command on line line
9513 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9514 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9515 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9516 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9517 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9518 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9519 Use eval more safely.
9520 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9521 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9523 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9524 lines, exposed by quoting of eval argument.
9526 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9527 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9529 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9530 initialization of `ac_cv_exeext', do not override it if it was
9531 already set, unless it was set to `no', for compatibility with
9532 Autoconf-2.13, and comment this.
9533 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9534 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9535 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9536 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9537 Document that this test may be overridden by setting
9540 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9542 Revert these two patches:
9544 2006-04-06 Eric Blake <ebb9@byu.net>
9545 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9546 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9549 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9550 Clean up _AC_COMPILER_EXEEXT* macros.
9551 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9552 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9553 ac_file to the name of the default output file and call
9554 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9555 initial `rm' of the candidate files...
9556 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9557 the same list in subsequent `rm' calls, and for the temporary
9558 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9559 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9560 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9561 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9562 no longer needed) by libtool. Make it a cache check.
9563 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9564 copied here by mistake.
9565 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9566 _AC_COMPILER_EXEEXT.
9567 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9568 _AC_COMPILER_OBJEXT directly.
9569 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9571 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9573 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9574 Fix description of how the buggy `sed' works.
9576 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9580 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9581 ENOLCK. Only mention `make -j' when applicable. Only raise
9582 fatal errors when `make -j' is involved. Improve error message.
9584 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9586 * doc/autoconf.texi (Here-Documents): We now know more about
9587 the variable expansion in here documents bug.
9588 Thanks to Tim Rice and Stepan Kasal.
9590 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9591 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9593 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9595 * tests/autotest.at (Multiline command from M4 expansion):
9596 No failure to be expected if the shell quotes newlines in
9597 commands in the `set -x' output. Report by Tim Rice.
9600 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9602 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9603 expansion in the here-documents used by config.status, as that
9604 runs afoul of the Korn shell version M-12/28/93d bug described in
9605 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9606 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9607 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9609 2006-05-23 Jim Meyering <jim@meyering.net>
9611 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9612 Fix typo introduced with 2006-04-02 change. It reversed the sense
9615 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9617 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9618 ac_dB slightly, to save bytes in the script.
9619 Max out at 50 lines, rather than 96; this is more likely
9620 (though not guaranteed) to avoid obscure 'sed' failures.
9622 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9624 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9625 `tr -d -' as bad option argument. Work around this by deleting
9626 an unrelated character.
9627 Report by Tim Rice <tim@multitalents.net>.
9629 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9630 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9631 Stepan Kasal <kasal@ucw.cz>
9633 * doc/autoconf.texi (Particular Programs): Do not promise that
9634 we always prefer the GNU version of the program, and that we
9635 search according to PATH; both rules can have exceptions.
9636 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9637 AC_PROG_SED. Move descriptions of limitations
9638 to the Limitations of Usual Tools section.
9639 (Limitations of Usual Tools) <sed>: Mention script length
9640 limitations with Solaris /usr/ucb/sed.
9641 <grep>: Fix wording for empty alternative. Mention that -c and
9642 -l should not be combined, and that -E and -F should not be
9645 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9646 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9648 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9649 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9651 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9653 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9654 AC_DEFINE is now passed to m4_pattern_allow.
9655 * NEWS: Mention that; likewise for AC_SUBST.
9656 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9657 the parameter to m4_pattern_allow.
9658 * tests/tools.at: Add a check for that.
9660 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9662 * lib/autoconf/status.m4: Fix typos.
9664 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9666 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9667 only the files that this macro generates.
9669 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9671 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9672 the HP-UX sed limitation of 99 commands, labels do not count.
9673 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9675 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9677 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9679 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9680 Import the following fix from coreutils:
9682 2006-01-13 Jim Meyering <jim@meyering.net>
9684 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9685 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9686 not double-quote uses of that variable, to accommodate the rare
9687 case in which getmntent is available in none of the libraries
9688 checked. This happens at least on FreeBSD 5.0.
9690 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9692 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9693 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9694 some other programs unwisely rely on these undocumented vars.
9695 But put in warning comments about them.
9696 Problem reported by Ralf Wildenhues in
9697 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9698 * NEWS: Document that these variables are intended to go away.
9700 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9702 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9703 and set the language to C++ (analogous to the equivalent Fortran
9706 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9707 * doc/autoconf.texi (C++ Compiler): Document it.
9708 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9711 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9713 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9714 that caused config.status to generate 100-command sed scripts; the
9715 portable limit is 99.
9717 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9719 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9720 variable `ac_d' instead of `d' to avoid infringing namespace.
9721 Report by Ralf Menzel.
9723 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9725 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9726 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9727 * tests/tools.at (autoconf: subdirectories): New test, taken from
9728 the corresponding problem report by Ralf Wildenhues in:
9729 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9731 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9732 Quote some uses of shell variables if they might suffer unexpected
9733 globbing. This doesn't fix all instances of quoting problems that
9734 I found, just the easy ones that look safe.
9735 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9736 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9737 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9738 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9739 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
9740 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9741 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
9743 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
9744 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
9746 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9748 * bin/autoreconf.in ($help): Reword according to the manual.
9749 Suggested by Olly Betts.
9751 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9752 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9754 * bin/autoreconf.in: Pass the directory argument to
9755 `require_configure_ac'. Fix comment.
9756 * tests/torture.at (Configuring subdirectories): Expose this.
9757 Reported by Olly Betts.
9759 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9761 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9762 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9763 Automake as follows:
9765 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9766 `$configure_in' instead of `configure.in', to preserve
9767 directory component.
9769 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9771 * config/config.guess, config/config.sub, config/texinfo.tex,
9772 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9774 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9776 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9777 test for C99 conformance; (bool) 0.5 is an integer constant
9778 expression, but (bool) -0.5 is not. Problem reported by Fedor
9779 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9781 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9783 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9784 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9785 Warn about obsolete install-sh files. Remove stray sentence
9786 fragment and fix cross reference.
9787 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9788 install -d; this undoes the 2006-05-10 change.
9789 (MKDIR_P): Mark with AN_MAKEVAR.
9790 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9791 that we don't require $INSTALL to be thread-safe. Move comments
9792 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9793 of AC_PROG_INSTALL. Output a message saying that we're checking
9794 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9795 MKDIR_P instead of AC_SUBST.
9796 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9797 Special magic for MKDIR_P, too.
9798 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9800 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9802 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9804 Sync from Automake, as follows:
9806 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9807 * config/install-sh: Initialize IFS, so field splitting isn't
9809 * config/mkinstalldirs: Likewise.
9810 * config/missing: Remove superfluous quotes. Replace all uses of
9811 `[' by `test', for consistency, and for..
9812 * config/missing (sed_minuso, sed_output): New variables.
9813 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9814 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9815 Fixes `missing' to detect `--output' for help2man. Fixes
9816 PR automake/483. Report by Dennis J. Linse.
9817 (autom4te): Document in `missing --help'.
9819 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9821 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9822 * config/install-sh: Don't use 'path' to talk about file names,
9823 as per GNU coding standards. Close a race condition reported by Ralf
9824 Wildenhues and Stepan Kasal. There is still a race condition
9825 on hosts that predate Posix 1003.1-1992, but we can't help this.
9826 Don't mishandle weird characters like space on pre-Posix hosts.
9827 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9828 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9829 AC_PROG_MKDIR_P from AS_MKDIR_P.
9830 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9831 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9832 earlier editions are not (including Automake 1.8.3).
9833 Do not suggest mkinstalldirs for thread-safety.
9834 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9835 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9836 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9837 presence of special characters and race conditions.
9838 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9839 in Autoconf's name space.
9841 2006-05-10 Bruno Haible <bruno@clisp.org>
9842 and Paul Eggert <eggert@cs.ucla.edu>
9844 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9845 from Automake with minor changes.
9846 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9848 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9850 * config/install-sh: Update to Automake CVS version, as follows:
9851 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9852 * lib/install-sh: Simplify the expr implementation of dirname.
9853 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9854 * lib/install-sh: Handle --, and diagnose unknown options.
9856 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9858 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9859 `./autom4te' to create `./testsuite', since the `all' target
9860 will ensure its presence, but `installcheck' should not create
9861 the uninstalled wrappers.
9863 * tests/torture.at (Unusual Automake input files): Skip if we
9864 detect automake < 1.8.
9866 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9868 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9869 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9870 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9873 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9875 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9876 munge (multiple) white space and other oddities.
9877 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9878 single quotes in variable assignment.
9879 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9880 and similar failures by adding multiple spaces, tabs, and other
9882 Report and different test suggested by Francesco Romani
9883 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9885 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9886 single quotes, we only need to search for single quotes; this
9887 both simplifies the search pattern, and makes us less
9888 susceptible to `echo' variations for arguments not containing
9890 (_AC_ARG_VAR_VALIDATE): Likewise.
9892 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9894 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9895 `$*' and IFS concatenation issue with traditional shells and
9896 bash-2.04. Report by Seanster@Seanster.com.
9898 2006-05-03 Bruno Haible <bruno@clisp.org>
9900 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9901 precisely which Mac OS X versions have the od problem.
9903 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9905 * doc/autoconf.texi: Use @option systematically.
9907 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9908 and Bruno Haible <bruno@clisp.org>
9910 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9912 (Integer Overflow): Mention the special case of integer division
9915 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9917 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9918 traditional shells like the Solaris one that do not use the
9919 first IFS character for assembling `$*'.
9920 Prompted by a related report from autoconf_bug@nro.ca.
9922 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9923 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9925 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
9926 Mention more problems with the -e option.
9928 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9931 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9933 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9934 in URLs to improve DVI formatted output (requires texinfo 4.6).
9935 (System Services, Systemology, Shellology): Likewise.
9936 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9939 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9941 (Runtime): Fix macro argument names to match description:
9942 `action-if-found' -> `action-if-true' and similarly.
9943 (Obsolete Macros): Likewise.
9944 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9945 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9946 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9948 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9950 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9953 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
9956 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9958 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
9959 /bin/sh set unsorted output.
9960 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
9961 * tests/local.at: Likewise.

9965 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
9966 (Integer Overflow, Null Pointers, Buffer Overruns):
9967 (Floating Point Portability, Exiting Portably): New sections.
9968 (Writing Test Programs): Fix some langauge. Recommend exiting
9969 with status 1, not merely nonzero. Clarify exit declaration.
9970 (Run Time): Move C exit status stuff to new Exiting Portably section.
9971 (Systemology): Mention Posix and levenez. Update v7 reference.
9972 (Portable Shell): Mention the Posix shell.
9974 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9976 * bin/autoconf.as (me): Replace by as_me.
9978 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9980 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9981 since as_me isn't set yet.
9983 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9985 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9986 a few minor bugs in this area.
9988 * doc/autoconf.texi (Programming in M4sh): Comment out the
9989 documentation of AS_BASENAME, for now.
9990 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9991 (Limitations of Builtins) <basename>: Do not refer to
9993 * bin/autoconf.as (me): Don't use AS_BASENAME.
9994 (dir): Remove the unused variable.
9995 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
9996 AS_DETECT_REQUIRED. All uses changed.
9997 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
9999 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
10000 (AS_BASENAME): Use "basename --" to protect against leading "-".

10002 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
10003 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
10004 (_AS_DIRNAME_PREPARE): Likewise.
10005 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
10006 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
10007 (AS_DIRNAME): Use "dirname --".
10009 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10011 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10012 of "run time" and "run-time" changed to "runtime", for consistency.
10013 * lib/autoconf/fortran.m4: Likewise (in comment).
10014 * lib/autoconf/functions.m4: Likewise.
10015 * lib/autoconf/general.m4: Likewise.
10016 * lib/autoconf/headers.m4: Likewise.
10018 * doc/autoconf.texi (Run Time): Document the exit status situation
10019 with more accuracy and detail.
10021 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10023 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10024 Archive is not officially `GNU' any more. Update URL.
10025 (Defining Directories): Likewise
10026 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10028 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10030 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10031 newline from the `trap' code to finish `config.log'; the NetBSD
10032 /bin/sh resets the exit status after an empty command, as
10033 documented in doc/autoconf.texi.
10034 Reported by Dalibor Topic <robilad@kaffe.org>.
10036 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10038 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10039 Suggested by Bruno Haible.
10041 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10043 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10044 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10045 Instead, just list the shells that we know work.
10046 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10047 changed. Be more cautious about the _cv_ variable.
10048 * tests/tools.at (Syntax of the shell scripts): Check the
10049 _cv_ variable once, at first, to avoid an internal autoconf error
10050 when sh -n does not work.
10052 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10054 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10056 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10058 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10059 use ">&-" since we're only 99.999% sure that this is portable,
10060 and since the MinGW bug is fixed in a different way.
10061 * lib/autotest/general.m4 (AT_INIT): Likewise.
10063 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10065 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10066 before opening config.log, to avoid hitting a bug on MinGW.
10068 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10070 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10071 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10072 This works around a MinGW bug reported by Eric Paire.
10073 Make sure that all writes to the log file append to it,
10074 rather than possibly losing data.
10075 * lib/autotest/general.m4 (AT_INIT): Likewise.
10077 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10079 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10082 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10086 * configure.ac (AC_INIT): Bump to 2.59d.
10088 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10092 * Makefile.maint (news-date-check): Do not require a leading `*'
10093 before the release date in NEWS.
10095 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10096 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10098 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10099 the instantiated file do not contain the string 'datarootdir'
10100 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10101 @mandir@, replace the reference '${datarootdir}' by the value.
10102 * tests/torture.at (datarootdir workaround): New test.
10103 * NEWS: Advertise this temporary fixup.
10104 Based on a patch by Bruno Haible, reported and analyzed by
10105 Paul Eggert and Noah Misch.
10107 2006-04-12 Eric Blake <ebb9@byu.net>
10109 * tests/autotest.at (Debugging a failed test): Fix comment.
10111 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10113 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10114 all the changes since 2006-04-07.
10116 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10118 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10119 succeeded, but `ln -s file dir' failed, take care to remove the
10120 leftover target before the next test, to prevent its spurious
10121 failure; also make sure `ln file dir' works before selecting it.
10122 Thanks to Keith Marshall for pointing this out.
10125 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10126 assignments in `at_debug_args', so that we put them correctly
10127 in the `run' script.
10128 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10129 Reported by Eric Blake.
10131 2006-04-11 Eric Blake <ebb9@byu.net>
10133 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10134 top-level tests after micro-suite has been run. Used in...
10135 (Debugging a successful test, Debugging script and environment),
10136 (Debugging a failed test): ...these new tests. The first of these
10138 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10139 macro, split out from...
10140 (AT_INIT): ...here, so that using -d also generates a run script.
10141 Document that -d inhibits top-level logging.
10142 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10143 inhibits top-level logging; debug scripts are created.
10145 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10147 * tests/autotest.at (Empty test, Empty check): New test to check it.
10149 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10152 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10154 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10155 the files if a problem appears. Make the empty *.at files
10156 read-only, too. Proposed by Ralf Wildenhues.
10158 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10160 * config/Makefile.am: Add comment to force updated Makefile.in.
10162 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10163 space only patch to this file, this patch causes the Makefile.in
10164 files that include freeze.mk to be updated, and thus have a
10165 newer time stamp again, which in turn makes a pristine CVS
10166 checkout have correct time stamps.
10168 * Makefile.maint (cvs-sv): New macro, to be used..
10169 (config.guess-url_prefix, config.sub-url_prefix)
10170 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10171 point to CVS text checkout of Gnulib files.
10172 (copyright-check): Bump current year.
10173 (announcement): Do not hard-wire `./announce-gen'.
10174 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10176 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10178 (wget_files): Update config.guess, config.sub, texinfo.tex by
10179 `wget-update', now that their URLs work again.
10181 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10183 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10184 Problem noted by Paul D. Smith.
10186 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10188 * doc/autoconf.texi: Remove unused words from word list.
10189 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10190 .x-sc_trailing_space: New files.
10192 * doc/standards.texi: Sync from gnulib.
10194 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10195 `LIBOBJDIR' as experimental.
10197 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10198 with a target directory; it's internally implemented as `cp'
10199 anyway, but since Autoconf advertises the possibility to use
10200 a target directory when LN_S is `ln -s', we need to find out.
10201 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10202 analyzed by Keith Marshall <keith.marshall@total.com>.
10206 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10208 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10209 confdefs.h as-is. In general, if it has backslash-newline or the
10210 like, then it doesn't work either to sort or to remove empty

10215 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10217 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10219 * lib/autom4te.in (Automake-preselections): Preselect
10222 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10224 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10225 apostrophe within a single-quoted string, as this is the usual
10226 tradition and is easier to read than '"'"'. Don't rely on the
10227 shell treating "$/" like '$/'. Use a more-consistent indenting
10228 style for the trap.
10230 2006-04-09 Eric Blake <ebb9@byu.net>
10232 * tests/autotest.at (Backquote command substitution),
10233 (Multiline backquote command substitution): Remove mistaken
10234 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10236 (Parenthetical command substitution, Multiline parenthetical
10237 command substitution): here.

10270 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,

10272 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10273 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10274 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10275 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

10299 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10301 2006-04-08 Stepan Kasal <kasal@ucw.cz>

10312 that contains braces.
10314 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10316 Revert the patch from 2006-04-01 and only improve
10317 _AS_DETECT_BETTER_SHELL:
10319 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10320 skip nonexistent directories.
10321 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10322 only shell candidates which exist.
10323 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10324 * lib/autotest/general.m4 (AT_INIT): No need to give three
10325 parameters to _AS_PATH_WALK.
10327 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
10328 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10330 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
10331 distinguish m4sugar macros.
10332 * tests/tools.at (autoupdating with aclocal and m4_include):
10333 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10334 test case by Noah Misch <noah@cs.caltech.edu>.
10336 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10338 Revert my change from 2006-03-17, in other words:
10339 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10341 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
10342 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
10345 2006-04-07 Eric Blake <ebb9@byu.net>
10347 * doc/autoconf.texi (Programming in M4sh): Document that
10348 AS_MKDIR_P exits the script on failure.
10349 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10351 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10353 * config/elisp-comp, config/install-sh, config/mdate-sh,

10369 Paul Eggert <eggert@cs.ucla.edu>,
10370 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10372 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10373 whether `set' quotes correctly: redirect stderr of the tested
10374 `set', and use a subshell, for Ultrix; use `sed' instead of
10375 `grep' for zsh `set' which may write binary output; match only
10376 at the beginning of a line, to avoid false positives.
10377 In order to avoid false positives by unrelated variables with
10378 multiline content, put the dump algorithm in a subshell and
10379 unset all variables containing newlines (except some which are
10380 special to the shell). Warn about cache variables that are

10388 * tests/mktests.sh: Reword comments.
10390 * tests/mktests.sh: Only skip internal macros starting with
10391 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10392 Update exclusion lists for the test suite to this end:
10393 (AC_ARG_VAR): Do test this now.
10394 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
10395 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
10396 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
10397 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
10399 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
10400 shell issue with double-quoted command substitutions of native

10422 * tests/Makefile.am (maintainer-check-posix):
10423 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
10425 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
10426 ac_config_<foo>s again, sometimes normalized, sometimes not.
10427 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10428 (AC_CONFIG_COMMANDS): Do not do so here.
10429 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10430 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10431 2005-07-25 rewrite. Noticed by Noah Misch.
10433 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
10434 _AC_PRESERVE_HELP_ORDER, ...
10435 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
10437 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
10438 inside m4_expand_once; it is redundant.
10440 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
10441 for --help from Cygnus `configure.'
10443 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
10445 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
10446 on a patch proposed by Ralf Wildenhues.
10448 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10450 * lib/autoconf/status.m4: Replace <space>''<tab> with
10451 <tab><space> where this makes sense.
10453 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
10454 Noah Misch <noah@cs.caltech.edu>
10456 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.

10458 * doc/autoconf.texi (Help Formatting): New node.
10459 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
10461 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10463 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
10464 lib/autoconf/specific.m4, lib/autoconf/status.m4,
10465 lib/autoconf/types.m4, lib/autotest/general.m4,
10466 tests/mktests.sh, tests/torture.at: White space cleanup:
10467 remove some SPACE before TAB, or add quoting ('' or @&t@).
10469 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.

10473 2006-04-05 Eric Blake <ebb9@byu.net>
10475 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
10476 empty test suite works.
10477 * tests/autotest.at (Empty test suite): Remove xfail.
10479 2006-04-05 Noah Misch <noah@cs.caltech.edu>

10482 TAGS to ac_config_<foo>s.
10483 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
10484 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
10485 normalizing it, consistent it with previous releases.
10486 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10488 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10490 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
10491 Use simplified args that Eric Blake originally suggested.
10493 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
10495 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10496 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10497 Use 'comm' rather than N instances of grep; this also fixes a bug
10498 whereby substrings were incorrectly matched, causing us to not
10499 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10500 (exclude_list): Exclude empty macros.
10501 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

10506 Switch from grep to awk syntax.
10507 (ac_exclude_script): Renamed from ac_exclude_egrep.
10508 (au_exclude_script): Renamed from au_exclude_egrep.
10510 2006-04-04 Noah Misch <noah@cs.caltech.edu>
10512 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
10513 a subdirectory subject to Cygnus `configure'.
10514 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
10516 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
10517 report request when we have no AC_PACKAGE_BUGREPORT.

10531 Reported by Albert Chin <china@thewrittenword.com>.

10547 * THANKS: Add myself.
10549 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10551 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
10552 to log, point to testsuite output tree.
10554 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
10556 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
10557 * doc/autoconf.texi (Function Portability): Mention that C++
10558 has trouble with 'exit'.
10559 (Guidelines): Test programs shouldn't use 'exit'.
10560 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10561 Remove; all uses removed.
10562 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

10582 Clean up _AC_COMPILER_EXEEXT* macros.
10584 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10585 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10586 ac_file to the name of the default output file and call
10587 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10588 initial `rm' of the candidate files...
10589 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10590 the same list in subsequent `rm' calls, and for the temporary
10591 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10592 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10593 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10594 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10595 no longer needed) by libtool. Make it a cache check.
10596 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10597 copied here by mistake.

11374 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11375 by the function rather than ignoring it.
11376 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11377 comparing its address. Intel's interprocedural optimization was

11427 suggested by Ben Elliston. Handle weird characters correctly.
11429 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11431 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11432 calls, so that the final expansion of this macro is shorter.
11433 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11434 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11435 the cleanup there. Use AS_VAR_* macros, to be more general.

11465 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11466 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

11482 Stepan Kasal <kasal@ucw.cz>

11485 first header appears, define AH_HEADER.
11486 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11487 Update limitations about when to call AC_CONFIG_HEADERS.
11488 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11489 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11490 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11491 ``Configuration Actions''; fix their index entries.
11493 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11494 options correctly. Process N-M as M-N if M is smaller than N.
11495 Process ranges correctly so that N-N will run only N.

11503 before passing the macro name to AH_TEMPLATE.

11524 Prepend to LIBS, not append, in examples.
11526 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11528 When building in place, set srcdir="."; suggested by Tim Van Holder.
11530 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11531 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11532 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11533 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11534 does not mean "no --srcdir option".
11536 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11538 * tests/autoscan.at (autoscan): New file.
11539 * tests/suite.at: Use it.
11540 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11541 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11543 * tests/autotest.at (Keywords): Test keywords combinations.
11545 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11547 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11548 add "2>&1"; gzip 1.2.4 prints help on stderr.
11550 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11552 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11553 was pushdef'ed twice while popped only once. Push it only once.
11554 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11556 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11558 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
11559 prefixed by mere "===", not "configure: === ".
11561 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11563 * Makefile.maint: Update from Bison.
11565 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11566 "<tab>" in comment, so that the point is understandable.
11568 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11570 Rewrite substantial part of lib/autoconf/status.m4.
11571 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11572 and CONFIG_COMMANDS are not processed in four separate loops.
11573 Instead, there is one main loop. This alows that the common code
11574 is expanded only once, thus config.status (and configure) is smaller.
11576 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11577 the AC_LIST_FILES and cousins macros are no longer used.
11579 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11580 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11581 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11582 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11583 contain the initialization, nor the for loop, nor the associated
11584 commands; all these go to ...
11585 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11586 _AC_OUTPUT_CONFIG_STATUS.
11587 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11588 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11589 (_AC_OUTPUT_FILE): The creation of the sed script ...
11590 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11591 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11592 _AC_OUTPUT_MAIN_LOOP.
11593 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11594 _AC_CONFIG_COMMANDS): Use ...
11595 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11596 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11597 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11598 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11599 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11600 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11602 (_AC_CONFIG_UNIQUE): Update.
11603 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11604 Replaced by this ...
11605 (_AC_LIST_TAGS): ... new common macro.
11606 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11607 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11608 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11609 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11610 this didn't belong to the `config commands' section.
11611 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11612 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11613 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11614 to the `config commands' section either.
11615 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11616 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11618 ... and many changes to the comments nearby.
11620 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11621 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11622 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11623 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11624 (#define header templates): The comment at the top of the generated
11625 header now includes the name(s) of the source file(s).
11627 Several unrelated small changes:
11629 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11630 parameter to AC_DIAGNOSE.
11631 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11632 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11633 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11634 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11635 with AU::AC_OUTPUT.
11636 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11637 in AC_OUTPUT doesn't double-quote it either.
11638 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11641 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11643 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11644 versions of Portland Group compiler produce single- and double-quoted
11645 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11646 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11648 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11650 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11651 This is a corrected version of yesterday's patch.
11653 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11655 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11656 path, too; insert a "===" to emphasize the line.
11658 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11659 ac_cv_build_alias to ac_build_alias.
11660 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11662 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11663 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11664 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11665 (AC_ARG_VAR): ... here.
11666 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11669 Keep a list of all precious variables and process them with one simple
11670 for loop, instead of expanding all commands, or, OTOH, complicated
11671 processing of output of "set".
11672 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11673 variable names in new macro...
11674 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11675 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11676 a loop to assign all ac_env_* and ac_cv_env_* variables.
11677 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11679 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11680 its value to shell variable ac_precious_vars and call
11681 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11682 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11683 _AC_ARG_VAR_VALIDATE.
11685 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

11704 They are generated by the Tru64 v5.1B shell.
11706 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11708 Fix my changes from 2005-07-01; reported by Noah Misch.
11709 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11710 description, the macro now accepts only a single tag.
11711 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11713 Fix cases when the varsions of Autoconf and Autotest don't match.
11714 Reported by Noah Misch.
11715 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11716 at_top_builddir, for compatibility with older autotest.
11717 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11718 is not set, use at_top_builddir, for compatibility with older

11723 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11724 Problem reported by Patrick Welche.
11726 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11728 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11729 sed substitution command, so that we allow | in program prefixes
11730 and program suffixes. (& is a problem anyway; we're not fixing
11732 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
11733 configure_input, top_builddir, srcdir, etc.
11734 * lib/autotest/general.m4 (AT_INIT): Likewise, for
11735 PATH_SEPARATOR in AUTOTEST_PATH.
11737 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11739 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11740 for loop over config.site files using `set', to allow
11741 directory names containing IFS characters.
11743 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11745 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11746 directories with weird names. Apparently some people like living

11765 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
11767 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11768 document to output the default config_* lists to config.status.
11769 Don't recognize option --file, if the functionality is not there.
11770 Likewise for --header; moreover, recognize --he and --h as shortcuts
11771 for --help in that case.
11773 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11774 matches the order of execution. No code changed.

11793 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11795 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11796 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11797 (AC_SUBST): Call it.
11798 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11799 the directory specific variables; but don't call it for configure_input.
11801 2005-06-28 Derek Price <derek@ximbiot.com>
11803 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11806 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11808 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

11810 due to limitations in Make syntax. Problem reported by Alexandre
11812 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

11825 from Justace Clutter.
11826 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11827 variable into diagnostic. Make the diagnostic an error, not a warning,
11828 because we really don't support spaces and suchlike in dir names.
11829 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11830 Don't worry about backslashes in srcdir; it can't happen now.
11831 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
11832 Simplify ac_optarg handling.

11841 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11843 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11844 that '\|' is not allowed in BREs; recommend using newline separated
11845 list of patterns instead of multiple -e options.
11847 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11849 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11859 (Special Shell Variables): Fix sed code this in the example.
11860 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11861 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11863 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11864 expand to the empty list. Don't use two pairs of m4_changequote,
11865 it's not necessary.
11867 2005-06-20 Derek Price <derek@ximbiot.com>
11869 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11871 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11873 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11874 * doc/autoconf.texi:
11875 Don't mention Solaris versions so much, if a
11876 problem is common to all extant versions of Solaris. Say "SunOS
11877 4" instead of "SunOS" for SunOS 4.
11878 (awk): Mention more of the limitations of traditional Awk.
11879 (cat): Don't talk about cat -v.

11886 to be compatible with glibc strverscmp.
11887 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11889 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
11890 on Mac OS X 10.4 reported by Peter O'Gorman in:
11891 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
11892 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11893 Use shell builtins rather than 'expr', to work around expr bug.
11895 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11897 * doc/autoconf.texi: "filesystem" -> "file system".
11898 "behaviour" -> "behavior".

11909 man pages every month.
11911 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11912 quotes and backslashes. Patch from Derek Price.

11921 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11922 -u, since it outputs chatter if the input files are the same.
11923 Problem reported by Ralf Menzel.
11925 2005-06-08 Derek Price <derek@ximbiot.com>
11927 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11928 renaming them since they are about to be redefined anyhow.
11930 2005-06-08 Derek Price <derek@ximbiot.com>
11932 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11933 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11934 Move m4_undefine to alphabetical order.
11936 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11938 * README: Recommend GNU M4 1.4.3 or later.
11939 * doc/autoconf.texi (Introduction): Likewise.
11940 Reword to avoid some formatting glitches.
11941 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11942 Clarify explanation of HP compiler bug.
11943 Redo example output tp match current CVS snapshot.
11944 Use @example.org in email addresses when the examples
11945 might get inadvertently cut-and-pasted into user code.
11946 Remove example of autom4te usage that doesn't seem to work now.
11947 Use modern AC_INIT (except when the example is meant to be
11948 shown with Autoconf 2.13).
11949 Update ksh info for Solaris 9 and later.
11951 Modernize description of Automake versions a bit.
11952 Don't claim a future version of Autoconf is near.
11953 * doc/install.texi: Reword to avoid some formatting glitches.
11955 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11957 * doc/autoconf.texi: Add [] to examples, so that the manual
11958 follows its own advice about quoting better.
11959 Reword to avoid some formatting glitches.
11960 * doc/installt.exi: Reword to avoid some formatting glitches.
11962 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11963 Tru64 ksh pattern matching bug. Reported against Libtool by
11964 Albert Chin <libtool@mlists.thewrittenword.com> and
11965 Nicolas Joly <njoly@pasteur.fr>.
11967 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11969 m4_cdr of one-member list was [[]] (one-member list containing an
11970 empty string) instead of [] (an empty list. Callers were skewed to
11971 match this misbehaviour. As a consequence of this:
11972 - m4_foreach([x], [], [foo]) expanded to `foo', while
11973 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11974 This bug has been fixed:
11976 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11977 expand to an empty string; print error msg if called without
11979 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11980 misbehaviour; handle [] and [[]] correctly.
11982 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11984 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11985 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11986 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11988 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11990 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11991 swallow records with more than 99 fields.
11992 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11993 parse the long line.
11995 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11997 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11998 swallow literals longer than 399. Reported by Ralf Wildenhues.
11999 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12000 to workaround this limitation.
12002 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12004 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12005 to gfortran, and make these the first two compiler names
12006 checked (following the general autoconf preference for gcc).
12008 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12010 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12011 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12012 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12014 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12016 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12017 expression of unbounded size when processing the --list
12018 option. This runs afoul of a limit of 399 bytes per regular
12019 expression on AIX. Problem reported by Ralf Wildenhues.
12021 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
12023 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
12024 * doc/autoconf.texi (Particular Headers): Reword example
12025 for multiline stdbool replacement.
12026 (Setting Output Variables): Reword text a bit. Don't
12027 give all the details about |#_!!_#|.
12028 Reword description of line replacement.
12030 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12032 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12033 now contain newlines, and substituted files must be referenced on
12034 a line alone; the sed scripts to substitute them are now very
12036 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12037 commands can be put in a sed script portably.
12038 * doc/autoconf.texi (Setting Output Variables): Document above
12039 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12040 use of multiline substitution.
12041 * tests/torture.at: No longer expect substitution of newline to fail.
12043 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
12045 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
12046 From Ralf Menzel (trivial change).
12048 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12050 * tests/local.at: Don't attempt to check for negated character
12051 classes in shell scripts. The test was too brittle.
12053 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12055 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12056 * doc/autoconf.texi (Limitations of Builtins): Document this
12059 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12061 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12062 common code; used in many places in the tree.
12063 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
12064 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
12066 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12068 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12069 messages when ac_unique_file is not found.
12070 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12071 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12072 commands, for consistency with AC_MSG_ERROR and such.
12074 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12076 * bin/Makefile.am: Merge the two rules for creating scripts.
12078 2005-05-23 Stepan Kasal <kasal@ucw.cz>
12080 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
12081 obsolete; it was never documented.
12082 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
12084 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12086 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12087 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12088 (ac_top_builddir): ... this ...
12089 (ac_top_build_prefix): ... to this; the old name is also kept, for
12090 backward compatibility.
12091 (ac_top_builddir_sub): New variable, without the trailing slash,
12093 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12094 * doc/autoconf.texi (Configuration Actions): Rename
12095 ac_top_builddir to ac_top_build_prefix.
12096 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
12097 at_top_builddir to at_top_build_prefix.
12098 * lib/autotest/general.m4 (AT_INIT): Likewise.
12100 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12102 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
12105 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12107 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12108 argument to m4_foreach. I guess it was necessary in the past,
12109 but I think it's a no-op now.
12111 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12113 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12114 ``cat <<_ACEOF'' commands to one.
12115 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12116 * lib/autoconf/status.m4: On various places, use expr instead of
12118 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12119 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12120 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12122 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12123 the wrong patterns between ``case'' and ``esac.'' The previous
12124 code had false positives.
12126 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12128 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

12171 2005-05-13 Stepan Kasal <kasal@ucw.cz>
12173 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
12175 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
12176 enough arguments, similarly as in m4_bpatsubsts.
12178 2005-05-12 Stepan Kasal <kasal@ucw.cz>
12180 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

12186 for absolute directory names in one loop.
12187 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
12188 abbreviations of --version and --debug.
12190 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12192 * doc/autoconf.texi (Autoconf Language): Be more precise about
12193 quoting rules. Problems noted by Stepan Kasal.
12194 Also, throughout this document, be more careful about white space.
12195 "blank", "white space", and "space" all have different meanings
12196 and we should be careful to say what we mean.
12198 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12200 Fix C++ related problems reported by Werner Lemberg.
12201 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
12202 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
12203 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
12204 avoid problems with C++ and throw.
12205 * tests/compile.at: .cpp, not .cc.
12207 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
12209 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12211 * doc/autoconf.texi (Generic Functions): Typos.
12213 2005-05-02 Gary V. Vaughan <gary@gnu.org>
12215 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
12216 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
12217 set by latest automake.
12219 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12221 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12222 outputs 0 on GNU/Linux these days.
12224 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
12226 * doc/autoconf.texi (Autoconf Language): Add more description
12227 about quoting heuristics.
12228 (Limitations of Builtins): Describe "set -" problems.
12230 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12232 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12235 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12236 by AC_DEFINE; it was a mistake.
12237 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12239 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12241 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12243 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12245 * doc/autoconf.texi (External Software): Quadrigraphs are not
12246 processed correctly in AS_HELP_STRING; avoid this in the examples.
12247 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12248 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12249 comment and reduce m4_default([foo], []) to [foo].
12250 (m4_strip): Update the explanation.
12252 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12254 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12255 Remove core.conftest.* too; it's generated by Tru64 5.1.
12256 Problem reported by Jennis Pruett.
12257 * lib/autoconf/functions.m4
12258 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12259 Don't bother to remove core files; AC_RUN_IFELSE should do that
12262 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12264 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
12266 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
12268 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

12271 2005-04-15 Stepan Kasal <kasal@ucw.cz>
12273 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
12276 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
12278 * doc/autoconf.texi (External Software, Package Options): Add
12279 examples showing how to implement --with-* and --enable-* options.
12281 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12283 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
12284 as well as configure.in. Problem reported by Gregorio Guidi.
12286 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12288 * doc/autoconf.texi (Particular Functions): Use gnulib's current
12289 pattern for alloca snippet.

12299 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
12301 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
12302 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
12304 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12306 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12307 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12308 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12309 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12310 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12312 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12314 * NEWS: The configure command now warns you if you attempt to use
12315 a directory whose name contains a special character like space,
12317 * doc/autoconf.texi (Installation Directory Variables): Allow
12318 "," in file names. Do not use \@; it's not a portable regexp.
12319 * bin/Makefile.am (edit): Likewise.
12320 * lib/Makefile.am (edit): Likewise.
12321 * tests/Makefile.am (edit): Likewise.
12322 * tests/semantics.at: Likewise.
12323 * tests/torture.at: Likewise.
12324 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
12325 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
12326 * doc/autoconf.texi (File System Conventions): Warn about
12327 unportable file names.
12328 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
12330 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12331 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12332 ac_pwd, and quote srcdir.
12333 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12335 * doc/autoconf.texi: Fix some systematic formatting problems.
12336 ".)" needs a following @: if not at the end of a sentence, and
12337 similarly for "!)". "etc." should be preceded by a comma.
12338 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12340 2005-03-22 Bruno Haible <bruno@clisp.org>
12342 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12343 argument is often called 'build-aux'.
12345 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12347 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12348 macro AC_TRY_LINK is obsolete.
12349 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12352 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12354 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12355 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12356 from a Common Lisp's `cl'.
12357 (AC_PROG_CXX): Behave according to the documentation: don't
12358 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12359 make the variable CCC precious; use `cl.exe', not `cl'.
12361 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12362 Alexandre Duret-Lutz <adl@gnu.org>
12364 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12365 /dev/null, as "configure" shouldn't read stdin, and this insulates
12366 us from problems (e.g., when testing for "cl"). Also, do this
12367 redirection before invoking "hostname" or "uname", and keep the
12368 original input stream available via...
12369 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12370 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12371 bother with "</dev/null" since it's now done at the top of
12373 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
12374 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12375 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12376 * doc/autoconf.texi (File Descriptor Macros): New section.
12377 (Printing Messages): Mention it.
12378 * tests/base.at (Input/Output): New test.
12380 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12382 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12383 newline if neither \c nor -n work, as that would output two
12384 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12386 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12388 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12389 This causes that any required macros inside will get before the if.
12390 * doc/autoconf.texi (autom4te.cache): A typo.
12392 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12394 Undo previous change, except keep the change to
12395 lib/autoconf/programs.m4 that replaced grep with shell
12396 pattern-matching. This is because net-snmp configure reads stdin.
12397 Reported by Noah Misch.
12399 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12401 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12402 from /dev/null, as "configure" shouldn't read stdin, and this
12403 insulates us from problems (e.g., when testing for "cl").
12404 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12405 before invoking "hostname" or "uname".
12406 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12407 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12408 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12409 "</dev/null" since it's now done at the top of 'configure'.

12411 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

12417 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12418 avoid thinking that Allegro Common Lisp's "cl" command is a C++

12423 * doc/autoconf.texi (Limitations of Usual Tools): Document that

12435 Fix some @code's that should have been @env's, and vice versa.
12436 Sort environment variable names.

12438 Don't recommend PATH_SEPARATOR=';' so strongly.
12439 Mention that $RANDOM might expand to the empty string.
12440 "symlink" and "soft link" -> "symbolic link".
12441 Improve mktemp description (reported by Bruno Haible).

12479 CPPFLAGS to `configure' instead of setting it in `configure'.
12481 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

12580 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12581 Update the long comment explaining it.
12583 m4_require no longer writes an ``is required by'' line to the
12584 execution stack. It contains only one bit of non-redundant
12585 information: that the macro was required, not called. And even
12586 this bit is useless in most situations: have you ever met a macro
12587 which both calls and requires the same macro?
12589 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12590 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12597 (_m4_require_call): Use it.
12598 * tests/m4sugar.at (m4_require): Expect output without the
12599 ``is required by'' messages.

12635 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12637 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12638 Warn about newline stripping in `` and $(). Update Solaris
12640 (Limitations of Builtins): Use expr "X...", not expr "x...", as
12641 X insulates us from future changes to Posix.
12642 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
12645 2005-01-19 Stepan Kasal <kasal@ucw.cz>

12691 (_m4_divert_n_stack): New macro; the expansion is
12692 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
12694 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12695 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12696 stored in _m4_divert_diversion or _m4_divert_dump.
12697 (m4_divert_pop): When the parameter is given, compare the symbolic
12698 name with the last diversion pushed on the stack. Previously, the
12699 current diversion was compared with the numeric value of the
12700 diversion given as the parameter.
12701 (m4_require): If the macro hasn't been expanded yet, call ...
12702 (_m4_require_call): this new macro.

12735 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

13009 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13010 "char c = '\200';" rather than "char c = 0x80;" as the

13015 to -qlanglvl=ansi. We don't want to disable extensions.

13128 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13129 "/usr/include", clear ac_x_includes instead of leaving it as "no"

13197 This isn't a complete fix but it's an improvement.
13199 * bin/autoconf.as (autom4te_options): New var.
13200 Use it instead of appending to AUTOM4TE, so that we can allow
13201 spaces in the build directory's absolute name.
13202 * bin/autoheader.in ($autoconf): Allow spaces in file names.

13253 with pdksh, too. Problem reported by Patrick Welche via

13256 useful for pkdsh, too.
13258 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13260 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13261 _AS_UNSET_PREPARE, so that we can use $as_unset directly.

13275 names like "aux". Problem reported by Eric Blake.
13277 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13278 by zero instead of array size, so that we can use any arithmetic
13279 constant expression (instead of requiring an integer constant
13280 expression). This allows us to test expressions like DBL_MAX <
13281 LDBL_MAX, which didn't conform to the C standard using the old
13283 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13284 now that we can do floating-point tests at compile time.
13286 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13288 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13289 and LDBL_EPSILON, as the resulting expression isn't an
13290 integer constant expression and violates the C standard.
13291 Problem reported by Nelson H. F. Beebe. Also, check
13292 for "L" suffix, and check that long double doesn't have
13293 worse range or precision than double, that mixed-mode
13294 arithmetic doesn't generate a diagnostic, that double
13295 constants fit in long double.
13297 2004-06-03 Kevin Ryde <user42@zip.com.au>
13299 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13300 malloc(0) and realloc(NULL,size).
13302 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13305 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13307 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13308 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13311 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13313 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13314 can be rewritten using if-then-else. Suggested by Bruno Haible.
13316 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13318 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13319 Problem reported by Stepan Kasal.
13321 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13323 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13324 change). Patch reported by Ralf Wildenhues in
13325 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13327 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13328 function F exists if the compiler and linker let you compile an
13329 expression like (F != 0). Recent versions of GCC optimize away
13330 the reference to F in that case, since every function address must
13331 be nonzero, so the link succeeds even if F does not exist.
13332 Problem reported by Manu in
13333 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13335 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13336 "Unix". Many uses changed.
13337 (Limitations of Builtins): Explain better why the ! command isn't
13340 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13342 * lib/autom4te.in (Automake-preselections): Preselect
13343 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

13347 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13348 referencing AC_FUNC_STRERROR_R.
13350 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13351 note pessimistic assumption when cross compiling.
13353 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13355 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13356 (until 2004) invoked subcommands with sh -e, contra POSIX.
13357 Reported by Kevin Ryde.
13359 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13361 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13362 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13363 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13364 `test -f " /usr/bin/grep"', which _always_ failed.
13365 (AC_PROG_SED): Ditto bogus PATH fix.
13366 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13367 requires that grep correctly supports _multiple_ `-e' options, rather
13368 than stating only that grep should accept `-e'.
13370 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13372 Port to C99, which requires that 'exit' be declared.
13374 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13375 to ensure that stdlib.h is included.
13376 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13377 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13378 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13379 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13380 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13381 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13382 when using 'exit' in a test; C99 requires that 'exit' be declared.
13384 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13386 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13387 now prefers 'grep' implementations that accept -e.
13388 (Limitations of Usual Tools): Describe problems of traditional
13389 egrep and fgrep with long input lines, and of traditional grep
13391 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13392 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13393 All callers changed. Append /usr/xpg4/bin to the PATH, for
13395 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13396 the user with complaints about multiple -e options.
13397 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13398 Define it with AC_PROG_GREP.
13399 * configure.ac (AC_PROG_GREP): Add.
13400 * lib/freeze.mk (GREP): New macro.
13402 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13404 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13405 a possible candidate only after all others fail, rather than
13406 consulting it first. This improves backward compatibility by
13407 better reflecting the way shell selection occurred in previous
13408 versions of Autoconf, and should help to avoid triggering latent
13409 problems in other packages, such as the one in Automake where zsh
13410 is not handled robustly:
13411 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13412 Although it is not Autoconf's responsibility to work around
13413 problems in Automake, it nevertheless makes sense to avoid
13414 introducing unnecessary incompatibilites.
13416 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13417 Gary V. Vaughan <gary@gnu.org>
13419 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13420 how deeply nested we are when a suitable tool is found, set the
13421 ac_path_TOOL_found flag.
13422 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13423 nested we are in this macro. Break out of all 3 nested loops if
13424 ac_path_TOOL_found is set.
13426 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13428 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13429 of the _AS_PATH_WALK loop too if GNU flavor is found.
13431 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13433 * doc/autoconf.texi (Limitations of Make): Update documentation
13434 for `$<'. New entry `Long lines', based on a report from Simon
13435 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13436 paragraph about DJGPP, based on a mail from Richard Dawe.
13438 2004-04-20 Paul Eggert <eggert@twinsun.com>
13440 * tests/c.at (C keywords): Don't assume that GCC supports
13441 "restrict" and "inline", as sufficiently-old GCC versions do not
13442 (also, GCC configured to be in pedantic C89 mode does not).
13443 Problem reported by Sumit Pandya in:
13444 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13446 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13447 consider -g to work if it generates warnings when plain compiles
13448 don't. Problem reported by Braden McDaniel in:
13449 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13451 * doc/autoconf.texi (Slashes): New section, to document a problem
13452 reported by Jim Meyering in:
13453 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13455 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13456 linker output files before linking, to work around IRIX 6 linker bug.
13457 Problem reported by Rainer Orth in:
13458 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13460 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13462 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13463 best tool so far counter rely on the tool path variable name to
13464 avoid checks for one tool being affected by the results of running
13465 the length check on a previous tool.
13467 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13468 match expression argument, as different greps have different
13469 regular expression flavours.
13470 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13472 (AC_PROG_EGREP): Pass 'EGREP$'.
13473 (AC_PROG_GREP): Pass 'GREP$'.
13475 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13477 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13478 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13480 2004-03-29 Paul Eggert <eggert@twinsun.com>
13482 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13483 Types, Specific Compiler Characteristics, System Services,
13484 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13485 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13486 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

13500 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13501 now defines HAVE_DECL_TZNAME if it is declared, when
13502 HAVE_STRUCT_TM_TM_ZONE is not defined.
13503 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13504 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

13509 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13510 superfluous backslashing of quotes (") in sed expressions;
13511 thanks to Paul Eggert.

13573 * bin/Makefile.am (edit): Don't use $< in a context where
13574 POSIX doesn't require support for it. Use $@.in instead.

13733 2004-01-26 Paul Eggert <eggert@twinsun.com>
13735 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13736 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13737 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13738 not <inttypes.h>. Problem reported by Tim Mooney in
13739 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13740 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13743 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13744 otherwise "make check" fails because it forbids cmp (I guess
13745 because cmp treats files as binary on DOS-like systems).
13747 * tests/mktests.sh: Update copyright date to 2004, since some tests
13748 have changed in 2004.
13750 2004-01-23 Gary V. Vaughan <gary@gnu.org>
13752 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
13753 non-truncating sed or gsed program in PATH.
13754 * tests/acprograms.at: Add it.
13755 * doc/autoconf.texi (Particular Programs): Document it.
13758 2004-01-15 Paul Eggert <eggert@twinsun.com>
13760 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13761 -std1 disables some useful extensions on Tru64. Problem reported
13762 by N. Lichtmaier in
13763 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
13765 2004-01-14 Paul Eggert <eggert@twinsun.com>
13767 * doc/autoconf.texi (Programming in M4sh): Document that
13768 AS_MKDIR_P succeeds if the destination is a symbolic link
13769 to an existing directory.
13770 (Limitations of Usual Tools): Note that mkdir -p might not
13771 succeed on symlinks to directories.
13773 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13775 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13776 * bin/autoheader.in: Grammar fix in message.
13777 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13778 Test for dir before calling mkdir -p. (trivial changes)

13783 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
13785 2004-01-10 Jim Meyering <jim@meyering.net>
13787 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
13789 2004-01-09 Paul Eggert <eggert@twinsun.com>
13791 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13792 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13793 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13794 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13795 AC_COMPILE_IFELSE, since we now assume our caller invokes
13796 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13797 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13798 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13799 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13801 2004-01-07 Paul Eggert <eggert@twinsun.com>
13803 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13804 `"'...'"`, as it's confusing (and I suspect it may not work on
13805 some platforms). The code was incorrect anyway, as it assumed
13806 that \$ evaluated to itself in that context. Reported by
13807 Alexandre Duret-Lutz.
13809 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13811 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13812 and _LT_AC_TAGCONFIG.
13814 2004-01-06 Paul Eggert <eggert@twinsun.com>
13816 * doc/autoconf.texi (One Macro Call): Fix an incorrect
13817 example, and add more examples. Reported by Eric Sunshine.
13819 2004-01-05 Paul Eggert <eggert@twinsun.com>
13821 * doc/autoconf.texi (Limitations of Usual Tools):
13822 Remove warning against "rm -fr" introduced yesterday; it
13825 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
13826 autoscan, autoupdate, ifnames): Don't use chmod -w.
13827 * lib/Makefile.am (autom4te.cfg): Likewise.

13835 by doing lineno substitution only on lines containing "$LINENO".
13837 2004-01-04 Paul Eggert <eggert@twinsun.com>
13839 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13840 Use "rm -f" to remove conftest.sed, not plain "rm".
13841 Bug reported by David Relson in
13842 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13844 * Makefile.am (autom4te-update):
13845 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13846 * Makefile.maint (my-distcheck, do-po-update): Likewise.
13847 * doc/autoconf.texi (Guidelines): Likewise.
13848 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

13854 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
13856 * doc/autoconf.texi (Limitations of Usual Tools):
13857 Warn against "rm -fr".
13859 2004-01-03 Paul Eggert <eggert@twinsun.com>
13861 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13862 -c -o might not work. From a suggestion by Kevin Ryde.
13863 (C Compiler, Generating Sources, Limitations
13864 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13865 Don't put '-o' after non-options, as POSIX doesn't allow this.
13866 Mention that cc's name might be gcc or c89 or whatever.
13868 2004-01-04 Kevin Ryde <user42@zip.com.au>
13870 * doc/autoconf.texi: Add various further index entries.
13872 2003-12-29 Paul Eggert <eggert@twinsun.com>
13874 * bin/autoreconf.in (autoreconf_current_directory):
13875 Fix typo: mkdir without umask arg.
13877 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13879 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13880 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13881 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13882 explanation clearer.
13884 2003-12-24 Andreas Schwab <schwab@suse.de>
13886 * doc/autoconf.texi (Default Includes): Fix misspelling of

13891 * configure.ac: Test if sh -n works.
13892 * configure: Regenerate.
13893 * tests/atlocal.in: Store the result here.
13894 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

13896 of explicitly testing.
13897 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
13898 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13899 * tests/tools.at (Syntax of the shell scripts): Simplify
13900 using AT_CHECK_SHELL_SYNTAX.

13902 AT_CHECK_PERL_SYNTAX.

13920 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
13922 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

13984 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13985 than $target since the latter is not usual, add guidelines on when to
13986 use or not use the system type.

14190 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
14192 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14193 cache variable instead of $G77 to decide whether to include -O2,
14194 since $G77 is specific to Fortran 77.
14196 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14198 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14199 free" flag. Re-order flags tested into rough order of popularity.
14201 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14203 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14204 arguments so that it can be used with syntax identical to
14205 AC_PROG_F77, and so that we can more easily decide to
14206 remove/deprecate the DIALECT optional argument in the future if it
14207 proves troublesome.
14208 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14209 non-freeform-supporting compilers. Document freeform flags.
14211 2003-10-03 Akim Demaille <akim@epita.fr>
14213 * configure.ac: Look for emacs, not macs.
14214 Reported by Eric Sunshine.
14216 2003-10-03 Akim Demaille <akim@epita.fr>
14218 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
14219 * bin/autoreconf.in (autoreconf_current_directory): Create the
14220 AUX_DIR if needed, for sake of automake --add-missing etc.
14221 Suggested by Alexandre Duret-Lutz.
14223 2003-10-03 Akim Demaille <akim@epita.fr>
14225 * configure.ac: Quotation and formatting changes.
14226 (EMACS): Don't set it if it is not recent enough to support

14272 Problem reported by Lars J. Aas in
14273 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14274 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14275 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
14276 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
14278 2003-09-26 Akim Demaille <akim@epita.fr>
14280 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14281 directory for AC_CONFIG_COMMANDS' first argument exists.
14282 This makes valid the invocation of _AC_SRCPATH that follows.
14283 Reported by Eric Sunshine.
14284 * doc/autoconf.texi (Configuration Commands): Adjust.
14286 2003-09-26 Akim Demaille <akim@epita.fr>

14293 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
14295 Actually, use AU_ALIAS.
14298 2003-09-26 Paul Eggert <eggert@twinsun.com>
14300 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
14301 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
14302 Problem reported by Eric Sunshine in:

14307 The test suite are sometimes assigning timings incorrectly.
14308 Reported by Henk Krus.
14309 Diagnosed by Nicolas Joly.
14311 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14313 Instead of making AT_help a sequence of assignments to grow
14314 $at_help_all, just make AT_help_all be the growing contents of
14315 $at_help_all, and make a single assignment in...
14317 (at_times_skip): Flip the meaning and rename as...
14318 (at_times_p): this.
14319 (AT_INIT): When summarizing the test that ran, remove
14320 $at_times_file after use, and check it is present before trying to
14323 2003-09-25 Akim Demaille <akim@epita.fr>
14327 * bin/Makefile.am (edit): Handle '@configure_input@'.
14328 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
14329 (ifnames): chmod -w.
14330 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14331 executables, not bin/ executables! Otherwise all the magic needed
14332 to find non installed files is turned off. This caused a failure
14333 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14334 as found in its environment (sent by tests/autoreconf): pointing
14335 to bin/autom4te that could not find its files.
14336 * tests/mktests.sh: Force the replacement of generated files, for
14337 the sake of "mv" program that are interactive when overwriting a
14339 * config/install-sh: Upgrade from CVS Automake.
14341 2003-09-23 Paul Eggert <eggert@twinsun.com>

14344 versus test -L issues.
14346 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
14347 Paul Eggert <eggert@twinsun.com>
14349 Trivial change to support GCC's configuration procedure.
14350 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
14351 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
14352 about inconsistency if the preprocessor is set to give errors for

14385 willing to edit the output files.
14387 2003-09-10 Akim Demaille <akim@epita.fr>
14389 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
14390 and AC_FC_FREEFORM.
14391 * tests/mktests.sh: Skip AC_FC_SRCEXT.
14392 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

14417 2003-09-04 Akim Demaille <akim@epita.fr>

14428 2003-09-04 Akim Demaille <akim@epita.fr>
14430 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
14432 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14434 Add support for newer Fortran dialects. The F77 interface is
14435 unchanged, and continues to support Fortran 77. New FC macros
14436 correspond to all the old F77 macros, with output variables FC,
14437 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14438 available dialect, but older dialects can be specified. There are
14439 new macros AC_FC_SRCEXT to set the source extension, and
14440 AC_FC_FREEFORM to accept free-form source files.
14442 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

14478 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
14479 are defaulted by AT_CHECK anyway.
14480 Use AT_CHECK_AUTOM4TE.

14556 Use &verb, not &verbose.
14558 2003-08-21 Akim Demaille <akim@epita.fr>
14560 * bin/autoheader.in (&parse_args): Use &parse_warnings and
14562 ($help): Use Autom4te::ChannelDefs::usage.
14563 * bin/autoscan.in: Use Autom4te::ChannelDefs.
14564 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14566 2003-08-21 Akim Demaille <akim@epita.fr>
14568 First stab at preserving warnings between calls to autom4te,
14569 including when the cache is used.
14571 There are still several issues: (i) there are too many runs of m4
14572 (one for include, one for warnings, and some more), (ii) warnings
14573 spreading on several lines are not handled gracefully, (iii) the
14574 code meant to have the call stack display for errors does not work
14575 (its handling should move from m4 to autom4te).
14577 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14579 (@preselect): Add m4_warn.
14580 ($exit_status): Remove, use $exit_code.
14581 ($help): Use Autom4te::ChannelDefs::usage.
14582 (&handle_m4): No longer define the m4_warnings.
14583 At each run, extract and report the warnings.
14584 Always cache the result, including if the exit status is on
14585 failure, since if nothing changes, we should result in the same
14586 failure, hence we can use the cache.
14587 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14588 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14590 (m4_warn): Redefine as a do-nothing: it is its invocation that
14591 matters, as warnings are now reported via traces.
14592 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14593 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14594 the latter reveals calls to the former.
14598 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

14627 Reported by Alexandre Duret-Lutz.

14631 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14632 * bin/autom4te: Adjust.
14633 In particular, be Autoconf tools are really silent when properly
14634 working, bind the verbosity of the 'note' channel to $verbose.
14635 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14636 (&xsystem, &contents): Remove, since they are exported by...

14708 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
14709 (AT_CHECK_NOESCAPE): Move core functionality to...
14710 (_AT_CHECK): ...this new macro.
14712 2003-08-07 Derek Price <derek@ximbiot.com>
14714 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
14715 (AT_CHECK_NOESCAPE): ...to this new macro.
14717 2003-07-31 Paul Eggert <eggert@twinsun.com>
14719 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
14720 in Bash 2.01. Problem reported by Brian Gough in

14725 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
14726 -lcrt1.o, for OS X. (trivial change)
14728 2003-07-07 Paul Eggert <eggert@twinsun.com>
14730 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
14731 inside '#ifndef __cplusplus'. Problem reported by
14734 2003-07-06 Bill Clarke <llib@computer.org>
14736 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
14737 'long', not 'int', for benefit of Sun's recent C++ compilers
14738 (trivial change). See:
14739 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

14745 * lib/Makefile.am (autom4te.cfg): Make it read only.
14746 Depend on Makefile since it contains substitutions.
14747 From Paolo Bonzini.

14755 From Gareth McCaughan.
14757 2003-06-23 Akim Demaille <akim@epita.fr>
14759 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14760 not all of them. This fixes 1. the fact that when testing
14761 Autoconf there are many many config.log, 2. the incorrect use of
14762 top_srcdir to find config.log.
14763 Don't mix the detailed output of failed test with the summary of
14764 failures. Rather, append detailed log afterwards.
14766 2003-06-23 Akim Demaille <akim@epita.fr>
14768 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
14769 always run: output config.log on $at_group_log.
14771 2003-06-23 Akim Demaille <akim@epita.fr>
14773 * tests/torture.at (#define header templates): Don't use quotes in
14774 C++ comments as it puzzles Emacs' sh font-lock-mode.
14776 2003-06-23 Akim Demaille <akim@epita.fr>
14778 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
14779 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
14780 * tests/atspecific.m4: Rename as...

14789 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
14790 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
14791 ensuring we add -std1 for full-ANSI.
14793 * doc/autoconf.texi (hdrindex): New macro.
14794 Add index entries for portability of various standard header files.
14796 2003-06-20 Akim Demaille <akim@epita.fr>

14804 2003-06-20 Akim Demaille <akim@epita.fr>

14811 * lib/autotest/general.m4: Use at_times_file only if used.
14814 2003-06-20 Akim Demaille <akim@epita.fr>
14816 * config/config.guess, config/config.sub, config/elisp-comp,

14822 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
14823 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
14824 (TEST_SCRIPT): New diversion.

14826 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
14827 (AT_INIT): Support for expected failures.
14829 2003-06-02 Akim Demaille <akim@epita.fr>
14831 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
14833 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
14834 Autoconf nor Automake.
14835 (&contents): New, from Automake.
14838 2003-05-28 Paul Eggert <eggert@twinsun.com>
14840 * NEWS, doc/autoconf.texi (Particular Functions),

14842 is the inverse of localtime.
14844 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
14846 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14847 (handle_exec_errors): New function. Work around $! being
14848 altered by WEXITSTATUS.
14849 (xqx, xsystem): Use handle_exec_errors.
14851 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14853 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14854 Do not call `_exit()', simply modify `$?'.
14855 (xsystem): Reset $! before running system, and check it afterward.
14856 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14857 63 for version mismatches.
14859 2003-05-23 Akim Demaille <akim@epita.fr>
14861 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14862 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14863 the middle of a line).
14864 * lib/m4sugar/m4sugar.m4: Likewise.
14865 Remove useless spaces in comments.
14867 2003-05-23 Akim Demaille <akim@epita.fr>
14869 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14870 exit 63, so that we (or Automake's "missing") can tell the
14871 difference with a plain failure.
14872 * doc/autoconf.texi (Notices): Adjust.
14874 2003-05-23 Akim Demaille <akim@epita.fr>
14876 * Makefile.am, bin/Makefile.am, config/Makefile.am,
14877 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
14878 White spaces cleanup.
14880 2003-05-22 Jim Meyering <jim@meyering.net>
14881 Paul Eggert <eggert@twinsun.com>
14883 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14884 Remove `#include <stdlib.h>' from the list; we should never
14885 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14886 resulting namespace pollution would cause other tests to fail.
14887 Configure scripts run with some older versions of g++ and HP's
14888 aCC would fail due to such an #include. Problems reported by
14889 Matthew Mueller in <http://bugs.debian.org/120704> and by
14891 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14892 In the test, use the test declaration before including <stdlib.h>,
14893 as that's closer to how it'll be used.
14895 2003-05-23 Akim Demaille <akim@epita.fr>
14897 * doc/autoconf.texi (Header Portability): ucred.h.
14900 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14902 Overhaul Autotest's logging: generate separate log files
14903 in testsuite.dir/NNN/testsuite.log, and append them to
14904 testsuite.log instead of re-running the test verbosely.
14906 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14907 file descriptor, write 0 to at_status_file instead of setting
14908 at_status=0, initialize some new variables (at_status_file,
14909 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14910 to rerun the tests, instead append the at_group_log to the
14911 at_suite_log when a test fails.
14912 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14913 with the AS_MESSAGE_LOG_FD redirected to stdout.
14914 (AT_CLEANUP): save the output status in $at_status_file
14915 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14916 its original place.
14917 (AT_CHECK): since tests are run with a redirected stdout,
14918 and used to be re-run in verbose mode, turn some $at_verbose
14919 into echo, and don't redirect the output of testing stdout
14922 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14923 the name of the debugging directory and information about
14926 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

15040 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
15043 2003-05-06 Akim Demaille <akim@epita.fr>
15045 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15046 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15047 by aclocal.m4 is changed it might require the importing of another
15048 m4 extension file, i.e., aclocal must be run.
15050 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15051 (&parse_args): Use --force with aclocal if required and supported.

15065 2003-04-29 Derek Price <derek@ximbiot.com>
15067 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15068 seperator with m4_append_uniq(). It doesn't work.
15069 (AT_CLEANUP): Add `;' to end of at_help_all.
15070 (AT_INIT): Allow --keywords to be specified more than once. When
15071 grepping $at_help_all for keywords, use the field and keyword
15072 seperators to ensure a complete keyword match. Alter at_prev handling
15073 to support the new --keywords behavior.
15075 2003-04-27 Karl Berry <karl@freefriends.org>
15077 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15078 align better with others. I also made some of the individual
15079 entries on one line, for brevity and to make it easier for me to
15080 sort my dir-example file in the Texinfo distribution :).

15147 header causes problems.
15149 2003-03-28 Akim Demaille <akim@epita.fr>
15151 * tests/torture.at (Configuring subdirectories): Require aclocal
15152 1.4, otherwise the test fails, as it does support configure.ac.

15175 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
15176 obsolete AC_HELP_STRING.
15177 (AC_HELP_STRING): AU_DEFUN to...
15178 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.

15241 * bin/ifnames.in: Add final newline to help and version messages.
15243 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15244 to cope with DOS-style absolute paths, when constructing
15247 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15248 When constructing paths with IFS=:, quote the path. If we're
15249 constructing a DOS-style absolute path, we don't want to split it
15252 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
15255 2003-02-25 Pavel Roskin <proski@gnu.org>

15272 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
15273 format starting with "-".
15275 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15277 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15278 is not portable inside Makefile.
15280 2003-02-20 Akim Demaille <akim@epita.fr>
15282 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15283 compiler says yeah, but preproc says nope, compiler is right.
15284 Conversely, prompt the reader to send a bug report to the
15285 maintainers of the package, not of Autoconf.
15287 2003-02-20 Klee Dienes <kdienes@apple.com>
15289 * bin/autoreconf.in (autoreconf_current_directory): Properly
15290 handle an empty aclocal.m4.

15295 $ac_prefix_program.
15298 2002-12-23 Paul Eggert <eggert@twinsun.com>
15300 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15301 innocuous variant befor including <limits.h> or <assert.h>. This
15302 works around a bug reported by Albert Chin: HP-UX 11i
15303 (and earlier versions) have a <limits.h> that declares
15304 gettimeofday and many other functions.
15306 2002-12-03 Paul Eggert <eggert@twinsun.com>
15310 * NEWS, configure.ac: Update version.
15312 * doc/fdl.texi: Upgrade to FDL version 1.2.
15314 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15315 nontrivially in main's body, so that f's external declaration is
15316 not optimized away in AIX. This should fix the bug reported by
15318 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15320 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15321 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15322 defined, to support freestanding compilers. This should fix the
15323 bug reported by Momchil Velkov in
15324 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15326 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15327 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

15358 Update from masters.
15360 2002-11-14 Akim Demaille <akim@epita.fr>
15362 * Makefile.maint: Sync with Bison, i.e.:
15363 (po-check): Scan .l and .y files instead of the
15364 .c and the .h files that they generate. This fixes the bug
15365 reported by Tim Van Holder in:
15366 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15367 Look for N_ as well as for _. Try to avoid matching #define for
15371 2002-11-14 Akim Demaille <akim@epita.fr>
15373 * doc/autoconf.texi (C Compiler): Compiling several files at once.
15374 From Paul Eggert and Albert Chin-A-Young.
15376 2002-11-14 Akim Demaille <akim@epita.fr>
15378 * doc/autoconf.texi (C Compiler): Solitary backslashes.
15379 From Paul Eggert and Albert Chin-A-Young.

15383 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15384 than assigning in main, to avoid HP cc +O3 optimizing it away.
15386 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15388 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15389 option. Process --recheck after parsing all options. Pass -q
15390 option to configure on --recheck.
15391 (AC_OUTPUT): Pass -q from configure to config.status.
15392 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15393 arguments to record.
15394 * doc/autoconf.texi (config.status Invocation): Document
15395 config.status -q option.
15397 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15399 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15400 Makefile.in if Makefile.am exists.
15401 (output): Strip `.am' from Makefiles. Don't
15402 output AC_CONFIG_FILES if no Makefiles were found.

15422 Reported by Ezra Peisach.
15424 2002-11-05 Akim Demaille <akim@epita.fr>
15426 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15428 We _have_ to stop using the old compatibility scheme that tried to
15429 avoid useless backslashes because Libtool 1.4.3 contains a
15430 AC_DEFINE([error_t], [int],
15431 [Define to a type to use for \`error_t' if it is not
15432 otherwise available.])
15433 We _have_ to quote the single quote and backslashes with \. The
15434 old compatibility scheme saw that ` was backslashed, and therefore
15435 did not quote the single quote. Hence before this patch, Autoconf
15436 was not compatible with Libtool.
15438 2002-11-04 Paul Eggert <eggert@twinsun.com>
15440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15458 ($help, $make, &parse_args, &autoreconf_current_directory):
15460 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15462 2002-10-31 Bruno Haible <bruno@clisp.org>

15480 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
15481 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15482 Make variable, not a shell variable.
15483 Suggested by Bruno Haible.
15485 2002-10-31 Akim Demaille <akim@epita.fr>
15487 * bin/autom4te.in (load_configuration): Reject #args out of any
15490 2002-10-31 Akim Demaille <akim@epita.fr>
15492 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
15493 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

15506 2002-10-29 Paul Eggert <eggert@twinsun.com>

15509 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
15510 Problem reported by Bruno Haible.
15512 2002-10-29 Akim Demaille <akim@epita.fr>
15514 * doc/autoconf.texi (Header Templates): Put also in words what the
15515 pictures says to assist free style readers.
15516 (Customizing autom4te): s/--cache=/--cache /.
15518 2002-10-29 Akim Demaille <akim@epita.fr>
15520 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
15522 sparc_address_test returns void.
15523 Use it with an argument, as prototyped.
15526 2002-10-29 Akim Demaille <akim@epita.fr>

15827 Reported by Alexandre Duret-Lutz.
15829 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15886 From Sam Varshavchik.
15888 2002-10-08 Akim Demaille <akim@epita.fr>
15890 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15891 aclocal invocation, as Gettext macros might not be visible to
15893 Instead of blindly running autopoint, scan configure.ac (not the
15894 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
15895 Reported by Paul D. Smith.
15897 2002-10-08 Paul Eggert <eggert@twinsun.com>

15902 * bin/autom4te.in (parse_args): Configure GetOpt with
15904 * doc/autoconf.texi (Invoking autom4te):

15927 * tests/torture.at (Configuring subdirectories): Be robust to

16151 2002-09-09 Akim Demaille <akim@epita.fr>
16153 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16154 looking for a replacement file.
16155 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16156 directory is relative.
16157 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16158 directory definition.
16159 Reported by Andreas Schwab and Jim Meyering.
16161 2002-09-06 Akim Demaille <akim@epita.fr>
16163 * doc/autoconf.texi (Setting Output Variables): Clarify what
16164 precious variables are.
16165 Suggested by Pontus Skoeld.
16167 2002-09-05 Akim Demaille <akim@epita.fr>
16169 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16170 (ifnames, autoscan, autom4te): Since we don't only depend on
16171 configure.ac variables (such as VERSION etc.), but also on prefix
16172 and so forth, depend on Makefile, not configure.ac.
16173 Reported by Alexandre Duret-Lutz.
16174 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16176 2002-09-05 Kevin Ryde <user42@zip.com.au>
16178 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16179 doesn't seem to be confined to ia64, just say "some versions".
16181 2002-09-04 Akim Demaille <akim@epita.fr>
16183 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16185 * Makefile.am (maintainer-clean-local): Remove.
16186 (MAINTAINERCLEANFILES): Remove COPYING.
16188 2002-09-03 Paul Eggert <eggert@twinsun.com>
16190 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16191 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16194 2002-09-03 Akim Demaille <akim@epita.fr>
16196 * configure.ac: Bump to 2.53d.
16197 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16198 as of today, on Automake's team suggestion.
16200 2002-09-03 Akim Demaille <akim@epita.fr>
16204 2002-09-02 Akim Demaille <akim@epita.fr>
16206 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16208 * configure.ac: Disable SITE_MACRO_DIR.
16210 2002-09-02 Jim Meyering <meyering@lucent.com>
16212 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16213 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16214 Also, tweak grammar: s/make sure to/be sure to/.
16216 2002-09-02 Paul Eggert <eggert@twinsun.com>
16218 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16219 directory names are generally preferable to physical names.
16221 2002-09-02 Akim Demaille <akim@epita.fr>
16223 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16224 Reported by Raja R. Harinath.
16225 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16226 * bin/autoupdate.in: Use error instead of die.
16228 2002-09-01 Paul Eggert <eggert@twinsun.com>
16230 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16231 ordinary shell concatenation rather than echo+tr+sed command that
16232 runs afoul of a long-line-related sed bug in Solaris 8.
16234 * bin/autoheader.in (parse_args): --warning -> --warnings.
16236 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16237 stdout, as traditional "ls" does.
16238 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16239 _AC_COMPILER_EXEEXT_O): Likewise.
16240 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16242 * bin/autoconf.as: Add --prepend-include option. This patch was
16243 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16244 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16246 * bin/autoconf.in, configure: Regenerate.
16248 * doc/autoconf.texi (Special Shell Variables): Mention
16249 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16251 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16252 MAILPATH and set PS1, PS2, PS4 to default values, to work
16253 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16254 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16255 the Autoconf documentation specifies; fall back to "unset" only if
16256 this fails. Use a shell for-loop for this rather than an m4 loop,
16257 to shorten the output script.
16259 2002-08-30 Paul Eggert <eggert@twinsun.com>
16261 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16262 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16263 for the CDPATH problem. Document PWD.
16264 (Limitations of Builtins): Document the problem that "cd $foo" and
16265 "ls $foo" may refer to different directories in shells conforming
16266 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16267 example, since the old example is now out of date.
16269 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16270 FOO" and "ls FOO" talk about different directories; this catches
16271 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16274 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16275 of rolling our own unset.
16276 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16277 in practice we needn't worry about CDPATH if unset doesn't work.
16279 * Makefile.in, aclocal.m4, bin/Makefile.in,
16280 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16281 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16282 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16283 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16284 tests/Makefile.in: Regenerate with Automake 1.6.3.
16286 * config/config.guess, config/config.sub, config/mkinstalldirs:
16289 * configure: Regenerate with self.
16291 2002-08-30 Kevin Ryde <user42@zip.com.au>

16301 2002-08-29 Akim Demaille <akim@epita.fr>
16303 * lib/Autom4te/General.pm (&xqx): New.
16304 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16305 hand, which is not portable.
16307 * bin/autom4te.in: Use them.
16308 Use &error instead of die.
16309 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16312 2002-08-17 Paul Eggert <eggert@twinsun.com>
16314 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16315 default list of compilers to try, since it was long ago superseded
16316 by the ksh fc builtin. Suggested by Steven G. Johnson.
16318 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16320 * doc/autoconf.texi (Invoking autom4te): End the option table,
16321 fixing a bug introduced by the previous patch.
16322 (Limitations of Make): Add a 'target lookup' subentry in the
16323 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16325 2002-07-29 Mark D. Roth <roth@feep.net>
16327 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16328 options and use $AUTOM4TE_PATH.
16329 * doc/autoconf.texi: Remove documentation of autom4te
16330 --include-envvar and --site-macro-subdir options and document
16331 use of $AUTOM4TE_PATH.
16332 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16333 arguments from each language section.
16335 2002-07-29 Paul Eggert <eggert@twinsun.com>
16337 * doc/install.texi: Include copyright symbol in copyright notice.
16339 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16341 (AM_MAKEINFOFLAGS): New macro.
16342 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16343 * Makefile.am (INSTALL): Use the new macros.
16344 Use -o rather than --output, since "missing" does not grok --output.
16346 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16348 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16349 comments do not always work. Never trust the exit status of
16352 2002-07-24 Kevin Ryde <user42@zip.com.au>
16354 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16355 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16357 2002-07-23 Paul Eggert <eggert@twinsun.com>
16359 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16360 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16361 apparently treats PATH="nonexistent" as if it contained ".".
16362 Bug reported by Stefan `Sec' Zehl.
16364 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16366 * doc/autoconf.texi (Limitations of Make): Mention the special

16626 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
16628 2002-05-17 Paul Eggert <eggert@twinsun.com>
16630 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
16631 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
16632 This improves on an earlier suggestion by H. Peter Anvin.
16634 2002-05-16 Paul Eggert <eggert@twinsun.com>
16636 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16637 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16638 Both macros now accept an optional source-dir arg.
16639 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16641 * NEWS: Document this.
16642 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16644 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16645 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16646 not for GNU extensions; this undoes part of the 2000-11-03 change,
16647 reverting to 2.13-compatible behavior.
16648 Add new optional argument DIR.
16649 (AC_FUNC_FNMATCH_GNU): New macro.
16651 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
16653 2002-05-08 Paul Eggert <eggert@twinsun.com>
16655 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16656 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16657 and it causes a 'test' syntax error if it fails.
16658 Bug reported by Stephen Gildea.
16660 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16661 If prototypes are supported, use them to check this at compile-time,
16662 instead of trying to check it at run-time. If we must do a run-time
16663 check, assume that setvbuf is standard when cross-compiling, as
16664 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16665 Bug reported by Paul D. Smith.
16667 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16668 argument specifying location of getloadavg.c. This removes a
16669 FIXME. This idea was taken from Jim Meyering's implementation in
16671 * doc/autoconf.texi (Particular Functions): Document this.
16672 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16673 that's what the code does; this fixes a bug reported by
16676 2002-05-03 Akim Demaille <akim@epita.fr>
16678 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16679 autopoint instead of gettextize.
16680 ($uses_alocal): Rename as...
16681 ($uses_aclocal): this.
16682 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16683 Suggested by Bruno Haible.
16685 2002-05-03 Akim Demaille <akim@epita.fr>
16687 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16689 2002-04-29 Paul Eggert <eggert@twinsun.com>
16691 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16692 files to be 1 second older; just set them to be the same time.
16693 Also, sleep 1 second after the first aclocal, to work around
16694 problems with sub-second time stamps on the input files.
16696 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16698 * doc/autoconf.texi: Mention "set -e -x" lossage
16699 under node "Limitations of Builtins".
16701 2002-04-29 Akim Demaille <akim@epita.fr>
16703 * doc/install.texi: Better wording for setting variables when
16705 From Christian Cornelssen.
16707 2002-04-29 Akim Demaille <akim@epita.fr>
16709 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16710 of lack of $LINENO support, then the test will compare the $LINENO
16711 in testsuite vs. the lineno in the test file. This is wrong, of
16713 Be sure to protect it.
16714 Reported by Patrick Welche.
16716 2002-04-25 Akim Demaille <akim@epita.fr>
16718 * doc/autoconf.texi (Obsolete Macros): Typo.
16719 Reported by Vladimir Volovich.
16721 2002-04-25 Akim Demaille <akim@epita.fr>
16723 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16724 than some of the input files, hence, on the second run of aclocal,
16725 if some of its input are younger, make them older.
16726 Suggested by Paul Eggert.
16728 2002-04-25 Akim Demaille <akim@epita.fr>
16730 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16735 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
16736 and ac_subst_vars be sh variables containing the list of
16737 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
16739 (_AC_INIT_PREPARE): Use them to log them.
16740 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16741 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16742 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16743 _AC_SUBST_FILES and _AC_SUBST_VARS.
16744 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16746 2002-04-24 Akim Demaille <akim@epita.fr>
16748 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16749 autoheader, so that automake does not complain about a missing
16750 config.h.in that was to be created.
16752 2002-04-23 Akim Demaille <akim@epita.fr>
16754 * bin/autoheader.in (parse_args): --warning takes an argument.
16757 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
16759 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

16804 Minor spelling and grammar fixes.
16806 * doc/autoconf.texi: Follow the outline suggested in the GNU
16807 Sample Texts sections of the Texinfo 4.2 manual. Most
16808 importantly, this makes sure that the copyright notices appear in
16809 all output formats. You probably need Texinfo 4.2 to generate

16850 From Oliver Kiddle and Peter Stephenson.
16852 Have M4sh perform minimal shell sanitizing.
16854 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
16856 (_AS_PREPARE): this new macro.
16858 (AS_INIT): Invoke AS_SHELL_SANITIZE.

16861 Adjust Autoconf and Autotest.

16872 * tests/wrapsh.as: New, precursor of wrapsh.in.

16874 on Autotest and M4sh.

16910 Use dnl, not the KILL diversion.
16912 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
16913 (AC_CONFIG_LINKS): here.
16915 Don't use the KILL diversion, as it kills spurious output, which
16916 results in failures being hidden.
16917 Use m4_defn where appropriate.
16918 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
16919 after the second argument.
16921 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
16922 syntax, as it is provided by M4sugar.

16987 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

16995 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16996 problem with here-document buffer boundaries.
16998 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16999 when reinvoking the shell, to work around problems with installers
17000 who put strange things like "cd" commands in their environments.

17025 (Limitations of Usual Tools): Add mkdir section.
17027 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17028 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17029 back on AS_DIRNAME to compute prefixes otherwise; this is
17030 roughly what mkinstalldirs does. That way, we need not have
17031 our own filename disassembler. The old disassembler did not
17032 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17034 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17035 Create at_test_all by a series of assignments,
17036 not by a single assignment of a long string. The latter causes ksh
17037 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17038 presumably because of a buffer overrun.

17045 says 'times: not found'.

17128 2002-03-04 Akim Demaille <akim@epita.fr>
17130 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17133 2002-03-04 Akim Demaille <akim@epita.fr>
17135 * doc/autoconf.texi (Transforming Names): Equality between target
17136 and host is irrelevant.
17137 (Specifying Names, Canonicalizing): Remove all references to the
17138 backward compatibility hooks. Rather, collect them all into...
17139 (Hosts and Cross-Compilation): this new section.
17140 * doc/install.texi (System Type): Ditto.
17141 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17142 that `--host' implies cross-compilation.
17144 2002-03-04 Akim Demaille <akim@epita.fr>
17146 * doc/autoconf.texi (Evaluation Macros): New.
17147 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17149 (_m4_foreach): Define the variant with immediate evaluation so
17150 that it contains exactly the items, not an expression which
17151 evaluation is the current item.
17152 (m4_re_string, m4_re_word): Don't over quote them.
17154 2002-03-04 Akim Demaille <akim@epita.fr>
17156 Instead of having stacking `shift's evaluated at the end, let
17157 `foreach' loops immediately evaluate them.
17159 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17160 $*. This is the n-th time I change my mind, but hopefully this is
17163 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17165 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17166 it was only a hack for m4_text_wrap.
17167 (m4_car2): Remove, replaced by...
17169 (_m4_foreach): Adjust.
17170 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17171 m4_bpatsubst for clarification.

17223 AC_PREFIX_PROGRAM fails with dashed program names
17225 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

17244 sure not to introduce newlines in at_groups.

17262 2002-02-05 Akim Demaille <akim@epita.fr>
17264 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
17265 to make sure they are up to date when `check' is run.
17267 2002-02-05 Akim Demaille <akim@epita.fr>

17281 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

17284 2002-02-05 Akim Demaille <akim@epita.fr>
17286 * bin/autom4te.in (&parse_args): Implement `frozen files are
17287 optional are the sum of the previous files on the command line'.
17288 Also, pass `--reload-state=' on them, so...
17289 (handle_m4): don't.
17290 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17291 (M4sh): Rely on M4sugar.
17292 (Autotest, M4sh, M4sugar): Use frozen files.

17329 2002-01-28 Akim Demaille <akim@epita.fr>
17331 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17332 AUTOTEST_PATH *after* it was set.
17333 Don't put `.' in the PATH: the user should be precise and `./' if
17334 needed. In addition, given that the test suite does some `cd', if
17335 `.' is in the path, the `tested programs' sections will report
17336 programs found in the test suite's directory, while during the
17337 tests (performed in their own directory), these programs are no
17338 longer visible. In other words, the results is confusing and
17340 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17384 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
17385 message on invalid options.
17386 * bin/autom4te.in (parse_args): Don't use
17387 Autoconf::General::getopt with non valid options.
17389 2002-01-17 Jim Meyering <meyering@lucent.com>
17391 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
17392 $ac_cv_exeext so we don't use an old, invalid, cached value.

17406 package.m4, since is really depends upon configure.ac, not
17408 * doc/autoconf.texi (testsuite Scripts): Adjust.
17409 * tests/Makefile.am (package.m4): New.
17410 EXTRA_DIST it since its a source.
17412 2002-01-06 Akim Demaille <akim@epita.fr>
17414 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17415 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17416 and PACKAGE_BUGREPORT from here...
17417 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17419 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17420 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17421 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
17422 * tests/tools.at (autoheader): Adjust.

17442 * doc/autoconf.texi (New Macros): Tweak wording.
17444 2001-12-14 Akim Demaille <akim@epita.fr>
17446 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17447 trailing files, don't apply `-rf' to files which might not be
17448 created by configure (core, core.*, and *.core), but just `rm -f'.
17449 Suggested by Jonathan Kamens.
17451 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

17475 2001-12-12 Kevin Ryde <user42@zip.com.au>

17478 forbidden file descriptors table.
17480 2001-11-26 Akim Demaille <akim@epita.fr>
17482 * bin/autoscan.in (%c_keywords): Build it at top level.
17483 Map to 1 in order to simplify its uses.
17485 2001-11-26 Akim Demaille <akim@epita.fr>
17487 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17488 Remove $filepath, useless.
17489 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17490 variables, they are really part of the tokens.
17491 Split the input line on spaces and then look for tokens.
17492 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17493 because of `lex$U.$(OBJEXT)'.
17494 (&scan_files): Use "@list" instead of join.

17500 Remove, replaced by...
17501 * tests/wrappl.in: Be common for all the Perl executables.
17502 In particular autoscan and autoheader want -I.
17503 * configure.ac: Adjust.
17504 * lib/autoscan/headers: errno.h is portable.
17506 2001-11-26 Akim Demaille <akim@epita.fr>
17508 * bin/autoscan.in (used): New.

17533 Test groups are now run two directories deeper.
17535 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,

17538 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17539 top_srcdir, builddir and top_builddir.
17540 Use `at_*dir' relatively to the directory containing the
17541 suite, use `*dir' when relatively to the current group dir.

17550 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17552 * doc/autoconf.texi (Using System Type): Add an example of `case
17553 $host' usage so people quit using `case $target' everywhere.
17555 2001-11-22 Akim Demaille <akim@epita.fr>
17557 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17558 spotted by Jim Meyering.
17560 2001-11-16 Paul Eggert <eggert@twinsun.com>
17562 This patch implements a `long double' suggestion by Oliver Kiddle.
17564 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17565 static, to catch errors if the value isn't known at compile-time
17566 and the compiler supports dynamic arrays. Change its name from
17567 `_array_' to `test_array' to avoid potential name clashes.
17568 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17569 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17570 better than double. Catch a bug in GCC 2.95.2 x86.
17571 * doc/autoconf.texi (C Compiler): Document the above.
17574 2001-11-13 Akim Demaille <akim@epita.fr>
17576 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17578 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17580 2001-11-13 Akim Demaille <akim@epita.fr>
17582 * lib/autotest/general.m4 (AT_INIT): After having run the test
17583 group, go back to the initial directory, not to at_suite_dir.
17585 2001-11-13 Akim Demaille <akim@epita.fr>
17587 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17588 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17589 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17591 (AT_CHECK_CONFIGURE): Use absolute paths.
17592 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17593 The problem is still the old one: there is no means in M4 (that I
17594 know about) to create a defining macro, because there is no means
17595 to create `$1' etc., therefore, the defining macro ``swallows''
17596 all the arguments meant to the defined macro.
17598 2001-11-13 Akim Demaille <akim@epita.fr>
17600 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.

17607 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17608 variable names when referring to a single test group, or to
17609 `suite' when referring to the whole test suite.
17610 `at_last_test' is removed: m4 compute at_format itself.
17611 (at_stdout, at_stder1, at_stderr): New variables.
17612 (AT_CHECK): Use them.
17614 2001-11-13 Akim Demaille <akim@epita.fr>
17616 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17618 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17619 Do it as soon as a test fails, don't wait till the end of the test
17621 Don't remove $as_me.[0-9]*, since these files no longer exist.
17623 2001-11-13 Akim Demaille <akim@epita.fr>
17625 * tests/tools.at: Use absolute paths, since we are no longer run
17628 2001-11-13 Akim Demaille <akim@epita.fr>
17630 Now that tests are running in their own private dir, there is no
17631 need to list the files to remove at the end of tests groups.
17633 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17634 (AT_data_files, at_data_files): Remove.
17635 (AT_CLEANUP, AT_DATA): Simplify.
17637 Remove the group dir if !debug && !failed.
17638 * tests/atspecific.m4: Adjust.
17640 2001-11-13 Akim Demaille <akim@epita.fr>
17642 Start a new layout for Autotest: `testsuite' creates
17643 `testsuite.dir' in which the at-check-line etc. files are to be
17644 found, and `testsuite.dir/003' where the test group 3 is run.
17646 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17647 at_check_line_file, at_format, at_test_normalized, at_group_dir
17649 Create the directories.
17650 Use absolute paths for at- files.
17651 (AT_CHECK): Adjust.
17653 2001-11-11 Michael Matz <matz@kde.org>
17655 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17657 (m4_car): Properly quote arguments.
17659 2001-11-13 Akim Demaille <akim@epita.fr>
17661 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17662 with stricter rules on LIBOBJS.
17664 2001-11-12 Paul Eggert <eggert@twinsun.com>
17666 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17667 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17670 2001-11-12 Akim Demaille <akim@epita.fr>
17672 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17674 2001-11-12 Akim Demaille <akim@epita.fr>

17679 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17680 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17681 specify to what the macro should be defined (typically to 1).
17683 2001-11-12 Akim Demaille <akim@epita.fr>
17685 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17688 2001-11-12 Akim Demaille <akim@epita.fr>
17690 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17691 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17692 definition used by Automake where LEX is +/- "${missing} lex" and
17693 `missing' itself contains variables.
17695 2001-11-12 Akim Demaille <akim@epita.fr>
17697 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17698 Now that M4sh pushes BODY, the comments were output at the end of
17701 2001-11-08 Akim Demaille <akim@epita.fr>
17703 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17704 that we can trace macros from aclocal.m4.
17705 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17706 obsoleted, and redirect to the former anyway.
17707 Reported by Ralf Corsepius.
17709 2001-11-08 Akim Demaille <akim@epita.fr>
17711 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17712 processed only if present.
17713 * tests/torture.at (Configuring subdirectories): Use autoreconf
17714 instead of successive calls to autoconf.
17715 Add a nonexistent subdirectory to exercise the patch above.
17716 Reported by Ralf Corsepius.
17718 2001-11-08 Kevin Ryde <user42@zip.com.au>
17720 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17721 doesn't accept .S files.

17728 * bin/autom4te.in (warn_forbidden): New.
17729 (handle_output): Use it.
17730 Read m4_pattern_forbid with messages.
17732 2001-11-05 Akim Demaille <akim@epita.fr>

17735 * lib/autom4te.in: Adjust.
17737 2001-11-05 Akim Demaille <akim@epita.fr>
17739 * tests/Makefile.am (testsuite): Rename this target as...
17740 ($(TESTSUITE)): this.
17743 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17745 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17746 the --prefix option, also remove it's argument.
17748 2001-11-05 Akim Demaille <akim@epita.fr>
17750 * doc/autoconf.texi (testsuite Invocation): Update.
17751 (Writing testsuite.at): Update.
17753 2001-11-03 Akim Demaille <akim@epita.fr>
17755 * doc/autoconf.texi: s/@code/@command/ where appropriate.
17757 2001-11-03 Akim Demaille <akim@epita.fr>
17759 * lib/Autom4te/General.pm: (&catfile, &canonfile)
17760 (&file_name_is_absolute): New, wrappers around routines from
17762 Use and export them.
17763 (&find_configure_ac): Optionally take a directory where to look at.
17764 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17766 Default @ARGV to `.', not find_configure_ac.
17767 (&autoreconf): Argument is a directory.
17768 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17769 * doc/autoconf.texi (autoreconf Invocation): Update.
17771 2001-11-03 Akim Demaille <akim@epita.fr>
17773 * lib/Autom4te/General.pm (@export_vars, @export_subs)
17774 (@export_forward_subs): New.
17775 Add basename, dirname, and fileparse.
17777 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
17778 Don't look for aclocal flags if we already know aclocal is not
17780 Move aclocal.m4t only if it exists.
17781 Reported by Ezra Peisach.
17783 2001-11-03 Akim Demaille <akim@epita.fr>
17785 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17786 passed on command line, defaulting to ./configure.ac if present.
17787 (&maybe_autoreconf, File::Find): Remove, unused.
17788 (&autoreconf): If autoconf is not used, don't try to trace.
17790 2001-11-02 Akim Demaille <akim@epita.fr>
17792 * configure.ac: Bump to 2.52g.
17794 2001-11-02 Akim Demaille <akim@epita.fr>
17798 2001-11-02 Akim Demaille <akim@epita.fr>
17800 * config/config.guess, config/config.sub, doc/standards.texi:
17801 * config/lispdir.m4: Update from masters.
17802 * configure.ac: Bump to 2.52f.
17804 2001-11-02 Akim Demaille <akim@epita.fr>
17806 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17807 Don't run aclocal when aclocal.m4 is not from aclocal.
17809 Don't run libtoolize and gettextize if --install is not given.
17811 2001-11-01 Paul Eggert <eggert@twinsun.com>
17813 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17814 be invoked before _AS_LINENO_PREPARE.
17815 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17816 than character ranges.
17818 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17819 invoking AS_BASENAME. Set the locale variables to 'C' if
17820 possible, as POSIX requires this to get the traditional
17822 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17824 2001-10-31 Paul Eggert <eggert@twinsun.com>
17826 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17827 with {}, as that triggers a bug in Bash 2.05.
17829 (_AS_LINENO_PREPARE): Use Sed rather than
17830 Awk. Fix the sed prepass to work even if there are multiple
17831 instances of $LINENO on the same line. Do not substitute for
17832 other variables like $LINENOT. Do not check file dates; such a
17833 check is unreliable on sufficiently fast machines, and removing
17834 the check makes the code simpler and more reliable. Check for
17835 output and chmod failures.
17837 * doc/autoconf.texi (Special Shell Variables): Document
17840 2001-10-31 Akim Demaille <akim@epita.fr>
17842 * tests/Makefile.am (atconfig): Remove this target, Automake
17845 2001-10-31 Akim Demaille <akim@epita.fr>
17847 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17848 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17849 provided, while it is optional.
17850 * configure.ac: Adjust.
17852 2001-10-26 Paul Eggert <eggert@twinsun.com>
17854 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17855 lib/Autom4te/Struct.pm:
17856 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17859 * doc/autoconf.texi (Special Shell Variables): Document some
17860 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17862 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17863 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17864 eval $LINENO is not portable in practice.
17866 2001-10-24 Akim Demaille <akim@epita.fr>
17868 * lib/Autom4te/General.pm (backname): New.
17870 2001-10-24 Akim Demaille <akim@epita.fr>
17872 * m4/: Remove, merged into...
17875 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
17877 * doc/autoconf.texi (Shellology): Mention the problems with bash
17878 2.05's use of ANSI quoting in its `set' builtin.
17880 2001-10-22 Paul Eggert <eggert@twinsun.com>
17882 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17883 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17884 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17885 POSIX decided to standardize on the int flavor of strerror_r.
17886 Always do char* test, as there's no reason not to.
17887 Assign to a char* var, to catch strerror_r that returns int*.
17889 * doc/autoconf.texi (Particular Functions):
17890 Document the above changes. Also, document the fact that
17891 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17893 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17895 2001-10-20 Akim Demaille <akim@epita.fr>
17897 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

17902 * lib/Autom4te/General.pm (&update_file): If destination is
17903 unchanged, remove the source.
17904 (&up_to_date_p): Don't be verbose, be debug.
17905 * bin/autoreconf.in: No longer support --m4dir.
17906 (&autoreconf): Display the full path of the configure.ac we are
17908 Trace it only once.
17909 Be sure to honor --force with gettextize.
17910 Always run aclocal.
17911 * doc/autoconf.texi: Adjust.
17913 2001-10-20 Akim Demaille <akim@epita.fr>
17915 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17917 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17918 `intl' is already present, as it refuses unless --force.
17919 (&parse_args): Use -I, --include instead of the old Autoconf
17921 ($localdir, $autoconf_dir): Remove.
17923 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17925 2001-10-19 Jens Petersen <petersen@redhat.com>
17927 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17943 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17945 * bin/autoreconf.in (autoreconf): Display the path to the
17946 configure.ac being studied.
17948 2001-10-18 Paul Eggert <eggert@twinsun.com>
17950 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17951 long, to work around a bug in the HP C compiler version HP92453-01
17954 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17955 (AS_BASENAME_EXPR): New macro.
17956 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17957 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17958 and fall back on 'sed' only if the other two fail. This makes
17959 AS_BASENAME act more like AS_DIRNAME.
17960 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17961 contains white space.
17962 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17963 Use AS_DIRNAME, since I think it's now DOS-friendly.
17964 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
17965 Allow "dirname //FOO" to return either / or //, as POSIX allows
17968 2001-10-10 Akim Demaille <akim@epita.fr>
17970 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

17976 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
17977 m4_define, since...

18014 (Syntax of the shell scripts): Don't.

18105 shell does not support LINENO, and if CONFIG_SHELL is unset or
18106 empty, and if we can find a shell that does support LINENO,
18107 then set CONFIG_SHELL to that shell and then re-execute
18108 ourselves with CONFIG_SHELL.
18110 2001-10-05 Paul Eggert <eggert@twinsun.com>
18112 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
18113 doesn't exist. Remove *.tmp, as a .tmp file is created during the

18155 compatibility with POSIX shells.

18184 Don't use nested parenthesization. This patch was originally
18185 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
18186 but somehow it didn't get incorporated then.

18194 Check for `expr' arithmetic overflow, and for compilation failure,
18195 and invoke a new argument $4 if either is discovered.
18196 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
18197 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

18231 * tests/fortran.at (GNU Fortran 77): there.
18232 * doc/autoconf.texi (autoconf Invocation): Fix the example:
18233 AC_TRY_RUN is about compilation, not shell commands.

18276 Don't compute at_srcdir nor at_top_srcdir.
18278 * tests/tools.at: Hence use top_srcdir.
18280 * tests/Makefile.am, tests/autoconf, tests/autoheader,

18338 * tests/Makefile.am (package.m4): Remove.
18340 2001-09-22 Akim Demaille <akim@epita.fr>
18342 Rely on `$LINENO' when possible instead of `__oline__'.

18361 2001-09-21 Akim Demaille <akim@epita.fr>
18363 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
18364 Suggested by Jim Meyering.
18366 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18368 * lib/autoconf/programs.m4: Use extensions listed in

18398 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18400 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

18407 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18409 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
18410 already have $file). Set output files to binary mode (helps avoid

18413 2001-09-19 Akim Demaille <akim@epita.fr>
18415 * lib/autotest/general.m4: Englishoes.
18416 From Tim Van Holder and Alexey Mahotkin.
18418 2001-09-18 Paul Eggert <eggert@twinsun.com>
18420 * doc/autoconf.texi (Common Shell Constructs): New node,
18421 documenting AS_DIRNAME.
18422 (Limitations of Usual Tools): Refer to it when discussing dirname.
18423 Also, update discussion of POSIX standard to reflect latest draft.
18425 * lib/autoconf/c.m4:
18426 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18428 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18429 Do not pass a first argument with leading '-'
18430 to expr, by parenthesizing initial integers that might be negative.
18432 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18433 now merely checks whether it is an error to pass an argument
18436 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18437 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18438 whether it is a (compile-time) error to pass an argument to
18439 getpgrp. This simpler test supports the revised documentation,
18440 and is all that AC_FUNC_GETPGRP's users really need.
18442 2001-09-18 Akim Demaille <akim@epita.fr>
18444 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18454 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18456 Add test for AS_BASENAME.
18457 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18458 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18459 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18460 * tests/base.at: Fixed the expected responses. The old ones were
18462 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18463 the documentation claims it should (and how it behaved in 2.13).
18465 2001-09-18 Akim Demaille <akim@epita.fr>
18467 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18468 the AC_CONFIG_COMMANDS invocation.
18469 This also solves the name clash problems.
18470 Don't set the package's ID.
18471 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18472 No longer to be shipped.
18473 (version.in): Remove.
18474 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18475 * lib/autoconf/status.m4: Adjust.
18476 Use `m4_PACKAGE_STRING'.
18477 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18478 the only optional argument is the name of the test suite.
18479 Expect `package.m4' to define the package signature.
18480 * lib/autom4te.in (Autotest): Add `package.m4?'.
18481 * tests/Makefile.am (package.m4): New.
18482 * tests/suite.at: ifnames is a victim.
18484 2001-09-18 Akim Demaille <akim@epita.fr>
18486 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18487 AC_LIBSOURCE, AC_CONFIG_FILES.
18488 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18489 program version string doesn't match the package's.
18490 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
18493 2001-09-17 Paul Eggert <eggert@twinsun.com>
18495 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18496 Allow expression to return any value that can fit into unsigned long
18497 (not int, as before). Check for output errors.
18499 2001-09-17 Bruno Haible <haible@ilog.fr>
18501 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18502 Always include <stdio.h> and <stdlib.h>. Evaluate
18503 the expression in an extra function before these includes. Call
18504 fprintf "%d" only after ensuring the argument is of type 'int'.
18505 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18507 2001-09-17 Paul Eggert <eggert@twinsun.com>
18509 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18510 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18511 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18512 when they don't exist.
18514 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18515 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18518 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18519 version with the version used by fileutils 4.1, except use
18520 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18523 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18525 2001-09-13 Akim Demaille <akim@epita.fr>

18533 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
18534 m4_defn'ing is valid.

18549 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
18551 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
18552 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
18553 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
18554 AT_tests_all for consistency.
18556 (AT_VICTIMS): Similar to AT_KEYWORDS.

18561 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
18563 2001-09-13 Akim Demaille <akim@epita.fr>
18565 * lib/autotest/general.m4 (AT_INIT): Create and remove
18566 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18567 test suites can cohabit.
18569 2001-09-13 Akim Demaille <akim@epita.fr>

18677 2001-09-05 Akim Demaille <akim@epita.fr>

18680 the maintainer is dumb enough to do that...
18682 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18683 excellence in M4 quotation: consider `__file__' is active.
18685 And BTW, when invoking m4, pass the --include in the right order:

18756 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

18860 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

18863 find the executables for it.
18864 * tests/Makefile.am: Major cleanup. Too lazy to document...
18865 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18867 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18868 indeed related to running the test suite, while passing
18869 --autoconf-dir and others is related to running non installed
18870 Autoconf executables. So don't do that, leave it to...

18872 * tests/autoscan: New.
18873 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

18892 2001-08-29 Akim Demaille <akim@epita.fr>
18894 * Makefile.maint (do-po-update): Wget refuses to overwrite files:

19050 (AMTAR): Help automake define it.
19051 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
19052 needed, 1.5 can have a macro and a target with the same name.

19281 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

19299 * doc/autoconf.texi: Work around Texinfo buglets.
19300 (Transformation Rules): One example is enough, users are expected

19306 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

19359 autom4te.cache (it's a directory, not a file.
19360 * Makefile.am: Ditto (but maintainer-clean-local).
19362 2001-08-15 Akim Demaille <akim@epita.fr>
19364 * bin/autom4te.in (@m4_warning): New.
19365 (&handle_m4): Use it.
19366 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

19436 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19438 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19439 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19440 * doc/autoconf.texi (C Compiler Characteristics): Update
19441 documentation for AC_C_BIGENDIAN.
19443 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19445 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
19446 magic values from an object file when cross-compiling.
19447 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19449 2001-08-10 Akim Demaille <akim@epita.fr>
19451 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19453 Suggested by Russ Allbery.
19455 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19457 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19458 current $prefix to the sub-configures.
19460 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19462 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19463 extension (needed on BeOS). Reported by Guido van Rossum.
19465 2001-08-09 Akim Demaille <akim@epita.fr>
19467 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19469 2001-08-07 Akim Demaille <akim@epita.fr>
19471 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19473 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19474 No need to remove the files before and after the each test, before
19475 each test and at the end of the suite is enough.
19476 Display only the children `times', not the shell's.
19477 If the test failed or was skipped, at-times is not available.
19479 2001-08-07 Akim Demaille <akim@epita.fr>
19481 Always produce testsuite.log, including when there are no
19482 failures. This helps getting information on skipped tests, and
19483 duration of the tests. Err, implement the latter btw.
19485 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19486 Dump information on the first run of each test.
19487 (AT_CLEANUP): Create `at-times' containing the duration of the
19490 2001-08-07 Akim Demaille <akim@epita.fr>
19492 The use of `dumpstat' revealed that `len' was used although it
19493 should not. m4_text_wrap was using it, but in the Autoconf world
19494 where it is legal. Hence (i) test M4sh in its own world, not
19495 Autoconf's, and (ii), ahem, fix the bug :)
19497 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19498 does not like `' instead of [].
