5475 forks when sanitizing PATH. Always output machine information,
5476 not just when atconfig was located.
5478 Add 'testsuite -C dir'.
5479 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5481 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5483 <DEFAULTS>: Delay computation of variables based on $at_dir...
5484 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5485 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5486 <PARSE_ARGS>: Parse new option.
5487 <HELP_TUNING>: Document it.
5488 * tests/autotest.at (Choosing where testsuite is run): New test
5490 (Keywords and ranges): Add test for missing -k argument.

5497 build-aux/texinfo.tex: Sync from gnulib.
5498 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
5501 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5503 * doc/autoconf.texi (Particular Programs): Do not mention the
5504 Autoconf version in which the AC_PROG_INSTALL change was done.
5505 Suggested by Paul Eggert.
5507 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5509 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5510 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5511 mode, we change to the source directory, also set $ac_pwd so we
5512 do not go back to the build tree for the next config subdir.
5513 * tests/torture.at (Deep Package): Extend test to contain two
5514 config subdirs on the top level.
5516 Fix parallel `maintainer-check'.
5517 * Makefile.am (maintainer-check-tests): Depend on `all'.
5518 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
5519 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
5521 (maintainer-check): Serialize the testsuite runs.

5567 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5568 (m4_require): Use m4_do, not m4_join.
5570 Fix some whitespace tests on cygwin.
5571 * tests/tools.at (autom4te and whitespace in file names): Restore
5572 font-lock. Create $TMPDIR before it might be used.

5575 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5577 Optimize AC_REQUIRE.
5578 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5579 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5580 (m4_require): Avoid extra macro calls.
5582 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5584 * tests/torture.at (srcdir): Fix quoting.
5586 Do not pass top_srcdir to configure scripts in testsuite.
5587 * tests/autotest.at (srcdir propagation): Copy install-sh to
5589 (my only test): Drop setting of `top_srcdir'.
5590 * tests/base.at (Input/Output): Likewise.
5591 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5592 config.guess, and config.sub to test source tree.
5593 Drop AC_CONFIG_AUX_DIR setting.
5594 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5595 * tests/torture.at (Substitute a 2000-byte string): Drop
5596 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5597 (Substitute a newline, datarootdir workaround): Likewise.
5598 (Define a newline): Adjust for linenumber changes in configure.ac.
5599 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5601 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5602 if `pwd` contains whitespace.

5606 * tests/tools.at (Syntax of the shell scripts): Likewise.
5608 * tests/m4sh.at (LINENO): Quote $0.
5610 Fix testsuite program wrapper for whitespace in `pwd`.
5611 The problem here is that the usual mantra is that command
5612 variables can contain arguments, thus we cannot just escape
5613 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5614 $top_builddir/tests directory early in $PATH, so that the
5615 wrappers are found by their plain name.
5616 * tests/wrapper.as: Put $testdir early in $PATH.
5617 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5619 Proper config.status --file/--header and $srcdir escaping.

5629 <at_func_create_debugging_script, Driver Loop>:
5630 Quote $at_group_dir.
5631 * tests/autotest.at (whitespace in absolute testdir): New test.
5633 * lib/autom4te.in: Quote @datadir@.
5635 Proper file name escaping in Autoconf programs and Perl modules.
5636 This includes escaping of characters special to the shell
5637 as well as special to Perl, e.g., leading `<' or `>'.
5638 For example, when $file starts with `>', `open ">$file"'
5639 wrongly tries to append to a different file.
5640 * bin/autoconf.as: Fix quoting for autom4te options.
5641 * lib/Autom4te/General.pm (shell_quote): New function, taken
5642 from coreutils, written by Jim Meyering.
5644 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

5651 * tests/tools.at (autom4te and whitespace in file names): Extend
5652 test. Test twice, with special characters allowed on w32, and the
5653 rest. Test leading and trailing whitespace, for `open_quote'.
5654 (autotools and whitespace in file names): New, analogous test.
5655 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5656 by Russ Allbery and Eric Blake.
5659 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5660 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5661 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5662 (update_file, contents): Use it.
5664 * Makefile.am (autom4te-update): Rewrite for git.
5666 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5668 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5670 Fix copyright years.
5671 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5672 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5674 2007-12-04 Eric Blake <ebb9@byu.net>

5682 * doc/Makefile.am (TEXINFO_TEX): Add.
5684 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5686 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5687 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5688 #undef as this runs afoul of our new way of creating config.h.
5689 Problem reported by Jim Meyering in
5690 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5706 `#AT_STOP_...' line at the end of each test.
5708 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5710 * lib/autotest/general.m4 (AT_INIT): For awk line number
5711 extraction script, ensure `$at_group' has a defined value
5712 even for the empty set, and properly quote its usage inside
5715 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5717 * doc/autoconf.texi (Shell Functions): New chapter. Document
5718 IRIX sh $0 issue in functions, move content from ...
5719 (Portable Shell): ... here.
5720 (Shell Script Compiler): Note that shell functions are not
5721 totally unportable any more.
5723 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5724 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5726 * lib/autotest/general.m4 (AT_INIT): Exit awk script after

5734 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5736 Fix IRIX testsuite debugging failures: $0 in functions.
5737 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5738 Do not use $0 inside a function, as IRIX sh will set that to the
5739 function name rather than the script invocation name.
5741 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5742 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5744 * lib/autotest/general.m4 (at_func_test): Use cached line numbers

5746 (AT_INIT): Extract and cache test script line numbers.
5748 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5750 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5751 subsequent fixups; the awk -> here-document conversion trashes
5752 performance too much with AIX sh.
5754 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5756 * tests/local.at: Do not test m4, perl with AT_TESTED.
5758 Diagnose and guard against write errors dealing with config.status.
5759 The general idea is this: all write failures from `configure'
5760 writing `config.status' are indicated by $ac_write_error, which
5761 is only checked at the end. This is safe because config.status
5762 code is not executed before the file is complete. Other write
5763 failures, be they inside config.status, or in sub shell/awk
5764 scripts spawned from configure or config.status, typically need
5765 earlier checking, as their results are used right afterwards.
5766 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5767 before writing config.status, check afterwards.
5768 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5769 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5770 Set `ac_write_error' for write failures to config.status. Barf
5771 upon write failures to temporary files.
5772 Adjust note about closing and reopening the here-document.
5773 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5774 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5775 reopening the here-document.
5776 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5777 Ensure `ac_write_error' does not escape into config.status.
5778 Also, add a couple of code paths not yet exercised in the test
5779 suite: a config file with input from stdin, and a config header
5781 Suggestion for catching write errors by Bruno Haible.
5783 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5785 Avoid error with Tru64 awk and testsuite lines with many words.
5786 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5787 reads the testsuite, set the field separator to an unusual value,
5788 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5789 even splits the input if $i, i>0, was never accessed in the script.
5791 Revert 2007-10-17 change.
5792 * TODO: Multiline args in config files and headers mean something
5793 different and are not fixed, see

5799 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5801 AC_*_TOOL does not canonicalize the prefix
5802 * doc/autoconf.texi (Generic Programs): Do not say that
5803 the *_TOOL macros canonicalize, they simply use the `host_alias'.

5807 Diagnose write errors in config.status instantiations.
5808 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

5855 Clean up the rule to create "expr".
5856 * tests/Makefile.am (expr): Don't redirect directly to target.

5863 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5864 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5865 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5866 These no longer check for preprocessor flaws.
5867 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5868 Do not check for preprocessor flaws.
5870 2007-11-13 Jim Meyering <meyering@redhat.com>
5872 Adapt dependencies, now that a version change doesn't modify configure.ac
5873 * GNUmakefile: Remove "make clean" kludge.

5876 Don't redirect directly to target.

5897 Add -v option to autoreconf invocation.
5899 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5900 * GNUmakefile (dummy): Remove INSTALL.
5902 Remove racy commands to build scripts in bin/ and tests/.
5903 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5904 are guaranteed to be built, remove the rules that tried to build
5905 them. Before, with a parallel build, these rules could lead to
5906 two processes writing tests/wrapper.in concurrently.
5908 Build in man/ only *after* building in bin/ and tests/.
5909 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5910 in both bin/ and tests/.
5912 Accommodate non-srcdir build-from-checkout.
5913 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5914 Use git's --git-dir=$srcdir/.git option.

5916 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5917 * configure.ac: Pass "." to git-version-gen.
5919 Avoid spurious test failures due to version skew.

5947 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5949 Ignore configure --help* errors due to LINENO-impaired shells.
5950 * tests/torture.at (Configuring subdirectories, Deep Package):
5951 In the --help* tests in read-only trees, make `.' temporarily
5952 writable again for the `stderr' file, and ignore errors due to
5953 the attempt to write configure.lineno.
5954 Report by Patrick Welche.
5956 2007-11-10 Jim Meyering <meyering@redhat.com>
5958 Generate package.m4 in build-dir, not srcdir.
5959 * tests/Makefile.am (package.m4): Adjust target.
5960 Don't redirect directly to $@.
5961 (CLEANFILES): Add package.m4.
5962 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5964 When running $(AUTOTEST), search "." before searching $(srcdir).
5966 Avoid a race condition that would make parallel "distclean" fail.
5967 * tests/Makefile.am (distclean-generic): Replace the default,
5968 automake-provided rule with an identical one, but with an additional
5969 dependency on distclean-local. Simply adding the dependency would
5970 cause automake not to emit the rule at all.
5971 * BUGS: Building with -jN works, now.
5973 Distribute git-version-gen.
5974 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5975 since GNUmakefile is distributed, and requires it for dist* rules.
5977 Remove two more generated files from version control.
5978 * INSTALL: Remove generated file.
5979 * lib/autoscan/autoscan.list: Remove generated file.
5981 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5983 * GNUmakefile (PATH): Remove stray apostrophes; they become
5984 part of PATH, which isn't wanted here.
5986 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5988 New config files output variable `top_build_prefix'.
5989 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5991 * doc/autoconf.texi (Preset Output Variables): Document it.
5993 Report by Bob Friesenhahn.
5995 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5996 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5997 function, to parametrize arithmetic with expr vs. the shell.
5998 Use it where possible.
5999 Suggestion by Benoit Sigoure.
6001 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6003 Adjust the documentation of autotest WRT atlocal.
6004 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6005 when using Automake, to write a rule to produce atlocal, since it's
6006 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6007 distributed, not atconfig.in.
6009 2007-11-04 Eric Blake <ebb9@byu.net>
6011 Update list information.
6012 * README: Mention new autoconf-commit list.

6019 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6021 * build-aux/.gitignore: Ignore mkinstalldirs.
6023 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6025 2007-11-03 Jim Meyering <meyering@redhat.com>
6027 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6028 * build-aux/git-version-gen: This syncs from coreutils.
6030 Adjust the build procedure so "make check" works reliably.
6031 * README-hacking: Include an extra step between "make" and
6032 "make check" to ensure that the latter passes.
6034 Use just-built tools, when possible.
6035 * GNUmakefile (PATH): Set and export here, ...
6036 (dummy): ... rather than here.
6038 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6039 and Andreas Schwab <schwab@suse.de>
6041 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6044 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6046 * configure.ac (AC_PREREQ): Require version 2.60, for
6047 AC_PROG_SED, AC_PROG_GREP.
6049 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6050 and Jim Meyering <meyering@redhat.com>

6059 2007-11-03 Eric Blake <ebb9@byu.net>
6061 Support m4 1.4.5 in testsuite.
6062 * tests/torture.at (Define a newline): Exclude line numbers in
6064 Reported by Ralf Wildenhues.
6066 2007-11-03 Jim Meyering <meyering@redhat.com>
6068 Remove automake-provided files from version control.
6069 * build-aux/elisp-comp: Remove file.
6070 * build-aux/install-sh: Remove file.
6071 * build-aux/missing: Remove file.
6072 * build-aux/mdate-sh: Remove file.
6073 * build-aux/.gitignore: New file.
6074 Suggestion from Ralf Wildenhues.
6076 2007-11-03 Eric Blake <ebb9@byu.net>
6078 Adjust version comparison to account for git snapshot numbers.
6079 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

6082 <m4_version_compare>: Document this change.
6083 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6085 2007-10-30 Bruno Haible <bruno@clisp.org>
6087 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6088 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6089 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6090 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6091 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6092 Suggested by Paul Eggert.
6094 2007-10-28 Jim Meyering <meyering@redhat.com>
6096 * README-hacking: Autoconf, Automake, and Perl are required to build.
6097 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6099 2007-10-28 Jim Meyering <meyering@redhat.com>
6101 README-hacking: Recommend running autoreconf -vi.
6102 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6103 so that we use just-built tools when they're available.
6104 Suggestions from Ralf Wildenhues.
6106 2007-10-28 Jim Meyering <meyering@redhat.com>
6108 Make inter-release --version output more useful.
6110 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6111 which indicates that it is built using the 19th change set
6112 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6113 is a prefix of the commit SHA1.
6114 * build-aux/git-version-gen: New file.
6115 * configure.ac: Run it to set the version.
6116 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6117 * Makefile.am (dist-hook): Arrange so that .version appears only
6118 in distribution tarballs, never in a checked-out repository.
6119 * .gitignore: Add .version here, too. Just in case.
6120 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6121 not configure.ac, now that the version number changes automatically.
6123 Ensure that $(VERSION) is up to date for dist-related targets.
6124 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6125 git-version-gen doesn't match $(VERSION), but only for dist targets.
6127 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6129 Fix `Deep Package' failure with a configure script early in PATH

6159 problem reported by Bruno Haible in
6160 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.

6164 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6167 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6169 Don't check for bug in HP-UX 11.00 cpp.
6170 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6171 Use -1ull rather than -1u, since that causes problems with gnulib; see
6172 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

6190 escaping of backslash in here-documents.
6192 Fix `Deep Package' test failure on FreeBSD.
6193 * tests/torture.at (Deep Package): Do not add `.' to $PATH
6194 unnecessarily. Do not try running `/bin/sh configure' with a
6195 configure script to be found in $PATH, if the shell does not do
6196 this resolution. Fixes test failure on FreeBSD.
6198 Fix config header generation with AIX awk.
6199 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6200 script, use helper array D_is_set, as `" 0"' does not evaluate
6201 to true for AIX awk.

6242 array of banner text from a special diversion.
6243 <PARSE_ARGS_END>: No longer need awk to find banners.
6244 <TESTS>: Banners are no longer processed by main driver loop, so
6245 we no longer need case statement.

6344 use $as_myself, not $0.

7422 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7423 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7424 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7425 works but the latter doesn't, then it's a valid type.
7426 This lets people use function types and so forth.
7427 For C++ there doesn't seem to be a simple solution, so leave it alone.
7428 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7429 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7430 AC_CHECK_TYPE; that wasn't documented or necessary.
7432 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7434 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

7518 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
7519 Reindent for sanity's sake.
7521 2007-02-24 Eric Blake <ebb9@byu.net>

7600 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7601 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7602 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7603 substitution will still be done by the special code.

7619 Report against Automake by Patrick Welche.
7621 2007-01-15 Stepan Kasal <kasal@ucw.cz>
7623 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
7625 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7627 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7628 early on the reader side, drop stderr of the input to avoid
7629 `broken pipe' error output; this may happen even with shell
7630 builtin `echo' of some bash versions. Reports by Ian Macdonald
7631 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7633 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7635 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

7646 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7647 * doc/autoconf.texi (Signed Overflow Examples): Give more
7648 discussion about the allow_superuser_privileges example,
7649 and change it a bit to make things clearer.
7650 (Optimization and Wraparound): Clarify whether the compiler
7651 will generate an infinite loop for the example derived from
7652 Autoconf's mktime test.
7653 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7654 Also, clarify unsigned multiplication overflow.
7656 2007-01-04 Eric Blake <ebb9@byu.net>
7658 * bin/Makefile.am (RELEASE_YEAR): New macro.
7659 (edit): Use it to supply correct copyright year to scripts.
7660 * bin/autoconf.as (version): Use it.
7661 * bin/autoheader.in ($version): Likewise.
7662 * bin/autom4te.in ($version): Likewise.
7663 * bin/autoreconf.in ($version): Likewise.
7664 * bin/autoscan.in ($version): Likewise.

7666 * bin/ifnames.in ($version): Likewise.
7668 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7670 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7671 feedback. The most important changes document what happens when
7672 you convert an out-of-range value to a signed integer type, and
7673 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7676 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7677 rewrite, taking notions from the recent discussion on the gcc and
7678 autoconf mailing lists; please see
7679 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7680 and follow the many links.
7681 (Integer Overflow Basics, Signed Overflow Examples):
7682 (Optimization and Wraparound, Signed Overflow Advice):
7683 (Signed Integer Division): New sections.
7685 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7687 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7688 preprocessor macro arguments in traced name.
7689 * doc/autoconf.texi (Defining symbols): Document longstanding
7690 support for AC_DEFINE-ing macros with arguments, and document
7691 behavior when the same variable has multiple AC_DEFINEs.
7692 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7693 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7694 macros directly, giving much shorter and simpler code.
7696 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7698 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7699 space before "$ac_configure_args" to prevent a 'config.status
7700 --recheck' failure if ac_configure_args doesn't contain a leading
7701 space. This works around a problem with the XEmacs configure.ac,
7702 which uses the (undocumented) ac_configure_args variable
7703 inconsistently with Autoconf.
7705 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7707 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7708 Include <limits.h>, and use its INT_MAX to rewrite the
7709 j loop so that it does not overflow 'int'. Problem reported by
7711 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7712 Play it safe by shifting left by 1 rather than multiplying by 2,
7713 as GCC is less likely to optimize this away when the value
7714 is signed (when it assumes overflow leads to undefined behavior).
7715 Also, don't assume time_t uses two's complement.
7717 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7719 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7720 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7721 dumps core on it. Report by Tim Rice.
7723 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7725 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7726 --disable-option-checking to --help output even when
7727 AC_PRESERVE_HELP_ORDER is not used.
7728 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7729 --with argument, rather than argument with [-.] replaced by
7731 * NEWS: Fix typo in previous change; the news was in the
7734 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7736 * NEWS: Warnings are now generated by default for unknown
7737 --enable-* and --with-* options.
7738 * doc/autoconf.texi (Option Checking): Renamed from
7739 (Configure Option Checking). Tighten up the wording a bit.
7740 (External Software, Package Options): Cross-reference to Option
7741 Checking, and use this to shorten our section.
7742 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7743 "$x" to test "x$foo" != x.
7744 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7745 Don't warn if $enable_option_checking is "no".
7746 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7747 ac_unrecognized_opts to the empty string.
7748 Don't echo the unrecognized opts, as this might mishandle
7749 backslashes or leading -.
7750 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7751 usage next to the other --disable-FEATURE options in the
7754 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7756 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7757 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7758 Print warning for unrecognized --with and --enable options
7759 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7760 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7761 Disable option checking when subdirs are configured.
7762 (AC_OUTPUT): If warnings are enabled, print warning about
7763 unrecognized --with and --enable options at the end of
7764 the configure output (as well as at the beginning).
7765 * doc/autoconf.texi (Option Checking): New node.
7766 Document new option warning functionality.
7768 2006-12-16 Eric Blake <ebb9@byu.net>
7770 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7771 * NEWS: Start news for current version.
7773 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7775 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7776 Define HAVE_GETMNTENT to 1, not to the empty string.
7777 Problem originally reported by Jochen Friedrich in
7778 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7780 This change prompted by a problem report by Andrey Simonenko in
7781 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7782 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7783 object-like macros only, in the traditional portable character
7785 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7786 Warn about attempts to define things that are not identifiers.
7787 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7788 awful hack that AC_DEFINEd macro names containing parentheses.
7790 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7792 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7793 too drastic, even if Texinfo in theory requires it for info mode.
7795 (config.status Invocation): Renamed back from Recreating a
7797 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7798 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7800 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7802 * NEWS: Version 2.61a.
7804 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7805 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7807 * NEWS: Document changes with echo and printf, and the lack
7808 of limits on the total size of multi-line values of substituted
7809 variables, and the AC_FUNC_FSEEKO fix.
7811 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7813 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7814 Writing configure.ac.
7815 (Autoconf Input Layout): Renamed from configure.ac Layout.
7816 (Recreating a Configuration): Renamed from config.status Invocation.
7817 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7818 (acconfig Header): Renamed from acconfig.h.
7819 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7820 (Writing Testsuites): Renamed from Writing testsuite.at.
7821 (Autom4te Cache): Renamed from autom4te.cache.
7823 * BUGS: Remove mention of VPATH problem, since it's now documented
7824 not to be a bug in the Autoconf build procedure itself, but rather
7825 a problem with the proprietary `make' programs.
7827 * doc/autoconf.texi (Build Directories): Add a cross reference
7830 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7831 * doc/standards.texi: Sync from gnulib.
7833 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7834 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7835 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7836 generated automatically.
7838 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7840 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7841 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7842 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7844 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7846 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7847 `CEOF$ac_eof' special marker, the awk script cannot contain a
7848 line matching `^CEOF', so this is not needed any more.
7849 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7850 special marker in the test.
7852 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7854 * tests/tools.at (autom4te preselections): Use `find -newer';
7855 remove one of the sleeps.
7857 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7858 more readable, using ...
7859 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7861 * doc/autoconf.texi (autoheader Invocation): Do not double-
7862 quote the parameter of `AH_BOTTOM' in the example.
7864 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7866 * doc/autoconf.texi (Configuration Headers): Remove the
7867 example with multiple input files.
7868 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7869 multiple input files.
7871 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7873 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7874 creating the awk substitution script, handle one input line at a
7875 time, so that the maximum length of a substituted (multi-line)
7876 value is not limited by the size of the sed pattern space.
7877 The trade-off is a slightly repetitive sed script.
7878 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7879 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7880 * tests/torture.at (Substitute a 2000-byte string): Increase the
7881 test with several long lines, they should not be caught by sed
7884 * tests/tools.at (autom4te preselections): New test, to flag
7885 entries missing from autom4te.cfg.
7886 Report by David Byron <dbyron@hheld.com>.
7888 * tests/torture.at (Substitute a 2000-byte string): Actually use
7889 AC_PROG_AWK, so the last change works as intended.
7890 (Substitute and define special characters): Likewise.
7891 (Substitute a newline): Likewise.
7893 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7894 instead of `awk' consistently.
7895 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7896 * tests/torture.at (Torturing config.status): Test both the
7897 result of AC_PROG_AWK and plain awk.
7898 (Substitute a 2000-byte string): Likewise.
7899 (Substitute and define special characters): Likewise.
7900 (Substitute a newline): Likewise.
7902 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7904 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7905 can be assigned to a function pointer. Problem reported by
7906 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7907 part of a patch by Ralf Wildenhues in that same bug report.
7909 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7911 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7912 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7914 2006-12-01 Eric Blake <ebb9@byu.net>
7916 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7917 cross-compiling from cygwin to mingw.
7918 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7919 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7920 to lib/autoconf/c.m4.
7922 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7924 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7925 string for more reliable failure. Wrap the entire test that
7926 causes the broken Solaris printf to dump core, in a subshell,
7927 so the segmentation fault message is reliably suppressed.
7928 Fix shell expansion errors by using /usr/ucb/echo always;
7929 avoid an error on systems without it by another subshell.
7930 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7931 subshell-$as_echo to `as_echo', for better error message.
7933 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7935 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7936 `BASH_SOURCE' contain a newline, set them to empty, as they may
7939 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7941 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7942 years and is too hard to maintain now. The last straw was
7943 reported by Jerker Baeck in
7944 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7945 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7946 * doc/autoconf.texi (Particular Functions): Move
7947 AC_FUNC_SETVBUF_REVERSED from here...
7948 (Obsolete Macros): ... to here. Say that it does nothing now.
7949 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7950 Turn into (almost) a no-op.
7952 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7954 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7955 These macros are obsolescent and new applications shouldn't need them.
7956 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
7957 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
7958 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
7959 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7960 (AC_FUNC_VPRINTF): Likewise.
7961 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
7962 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
7963 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7965 * doc/autoconf.texi (Setting Output Variables): Mention that
7966 @VAR1@VAR2 has unspecified behavior. Problem reported by
7968 * NEWS: Mention this.
7970 * Makefile.am: Put only a single '#' into the copyright notice,
7971 so that it's also present in the output file. Standardize wording
7972 in makefile copyright notices to match GNU coding standards.
7973 * bin/Makefile.am: Likewise.
7974 * doc/Makefile.am: Likewise.
7975 * lib/Makefile.am: Likewise.
7976 * lib/freeze.mk: Likewise.
7977 * lib/autoconf/Makefile.am: Likewise.
7978 * lib/autoscan/Makefile.am: Likewise.

7980 * lib/m4sugar/Makefile.am: Likewise.
7981 * man/Makefile.am: Likewise.
7982 * tests/Makefile.am: Likewise.
7983 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
7986 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7988 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7989 in the sed script that mangles the awk script: delete up to the
7990 first exclamation mark only.
7991 * tests/torture.at (Substitute and define special characters):
7994 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7996 Rewrite config files generation: avoid quadratic growth in
7997 the number of substituted variables by using awk instead of sed
7998 for the bulk of the substitutions.
7999 * NEWS: Mention this.
8000 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8001 forbidden in the output (and thus input) file.
8002 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8003 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8004 generate just one large awk script for substitutions,
8005 eliminating much of the earlier complexity, while adding some
8006 new complexity. Only expand the substitution templates at
8007 configure time, for smaller configure script size. If
8008 _AC_SUBST_FILES are used, test 'awk' for working getline support
8009 at config.status time. If absent, interpolate through the
8010 shell. The awk script was written with much help
8011 from Paolo Bonzini and Paul Eggert.
8012 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8013 (_AC_SED_FRAG_NUM): Likewise.
8014 (_AC_SUBST_CMDS): Renamed from...
8015 (_AC_SED_CMDS): ...this.
8016 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8017 * tests/torture.at (Substitute a 2000-byte string): Also
8018 substitute a line with 1000 words, and a variable with several
8020 (Substitute and define special characters): Test awk special
8021 characters, and put substitution input strings `@foo@' in the
8022 output, to test that no recursion happens; test several other
8023 combinations from Paolo Bonzini.
8025 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8027 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8028 that replaced echo with AS_ECHO where this wasn't necessary.
8029 Problem reportd by Ralf Wildenhues.
8030 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8031 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8032 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8034 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8036 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8038 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8040 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8041 that traditional Awk lacks 3-arg "split". It has it.
8042 Mention that FS must be a single character, and a few other
8043 99-byte limits of traditional Awk.
8044 Mention that if (i in a) doesn't work with traditional Awk.
8046 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8048 * tests/autotest.at (BSx641-newline in command):
8049 (BS-BS-newline in command, BSx640-newline in command):
8050 (Newline-CODE-BS-newline in command):
8051 (Single-quote-BS-newline in command):
8052 (Single-quote-newline-BS-newline in command):
8053 Use printf '%s\n' instead of echo, for portability to hosts
8054 where echo interprets backslashes. This will break on hosts
8055 that lack printf, but for now let's assume all such hosts
8056 are dead (if not, we should get reports of test failures).
8058 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8060 'echo' has some portability problems, when given a first argument
8061 with a leading '-', or when given any argument containing '\'.
8062 Avoid using 'echo' in these cases.
8063 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
8064 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
8065 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8066 * lib/autotest/general.m4 (AT_INIT): Likewise.
8067 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
8068 argument might be unportable.
8069 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
8070 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
8071 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
8072 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
8073 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
8074 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
8075 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
8076 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
8077 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
8078 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
8079 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
8080 (AC_PROG_MAKE_SET): Likewise.
8081 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
8082 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
8083 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
8084 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
8085 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
8086 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
8087 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
8088 * bin/autoconf.as: Redo verbose flag implementation, as the old
8089 scheme wouldn't work with AS_ECHO.
8090 * lib/autotest/general.m4 (AT_INIT): Likewise.
8091 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8092 Don't use ECHO_T, since ECHO_N is now reliable.
8093 * lib/autotest/general.m4 (AT_INIT): Likewise.
8094 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8095 rather than using a here-document to put the script into a file.
8096 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8098 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8099 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8100 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8101 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8102 * lib/autotest/general.m4 (AT_SETUP): Likewise.
8103 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
8104 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8105 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
8106 operand, as AS_ECHO requires. Avoid double file name expansion.
8107 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8108 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8109 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8110 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8111 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8112 Double-quote strings that would otherwise contain M4 comments.
8113 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8115 * configure.ac (AC_INIT): Bump to 2.61a.
8118 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8122 * configure.ac (AC_INIT): Bump to 2.61.
8125 * tests/autotest.at (Macro with backslash in a test title):
8126 Comment out for now, as this tests neither fails nor passes
8127 reliably. Problem reported by Ralf Wildenhues.
8129 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8131 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8132 in previous change, which caused test failures.
8134 2006-11-16 Stepan Kasal <kasal@ucw.cz>
8136 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
8137 code for --enable, --disable, --with, and --without to...
8138 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8139 * doc/autoconf.texi (Package Options):
8140 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
8142 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8144 Import these changes from config via gnulib:
8146 2006-11-15 Ben Elliston <bje@gnu.org>
8148 From Josselin Mouette <joss@debian.org>:

8201 first argument may also contain dots.
8203 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
8205 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
8206 benefit of platforms like Solaris+GCC where it is common to have a
8207 non-working g++ installation.
8209 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8210 and Joel E. Denny <jdenny@ces.clemson.edu>

8214 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
8217 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8219 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8220 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
8221 Imported from a similar patch to gnulib by Bruno Haible.
8223 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8225 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
8226 * doc/autoconf.texi (C Compiler): Document them.
8227 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
8228 New macros, taken from gnulib.

8236 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8238 * tests/torture.at (Configuring subdirectories): Do not skip
8239 Automake 1.10 nor future Automake 11.1 (sic).
8241 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
8242 and Stepan Kasal <kasal@ucw.cz>
8244 Handle special characters in test case titles correctly.
8245 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8247 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8248 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8249 argument. Extend to check titles printed by ./micro-suite and
8250 ./micro-suite -l and the title in micro-suite.log.
8251 (Backquote in a test title,
8252 Single-quote in a test title,
8253 Double-quote in a test title): Don't expect failure anymore.
8254 (Backslash in a test title): Put a non-whitespace character after the
8255 backslash so that Bourne shells might actually see it as an escape
8257 (Brackets in a test title,
8258 Pound in a test title,
8259 Comma in a test title,
8260 Quoted Macro in a test title,
8261 Macro in a test title,
8262 Macro with single-quote in a test title): New tests.
8263 (Macro with backquote in a test title,
8264 Macro with double-quote in a test title,
8265 Macro with backslash in a test title): New tests expected to fail.
8266 * tests/torture.at (#define header templates): M4-quote this title in
8267 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8268 The visible effect was a stray [] in the testsuite output.
8270 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8272 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8273 `trap ... 0' inside a function, for AIX sh.
8275 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8277 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8278 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8279 5363) simply issues a warning when dividing by zero at compile
8280 time. Problem reported by Elias Pipping.
8282 2006-10-26 Eric Blake <ebb9@byu.net>
8285 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8286 show effect on macros that expand with commas.
8287 Reported by Joel E. Denny.
8289 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8290 Also work with M4 1.4.8.

8297 2006-10-25 Stepan Kasal <kasal@ucw.cz>
8299 * tests/tools.at (autom4te --force): New test, verifies that
8300 `--force' always rewrites the output file.
8302 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8304 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
8305 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
8307 2006-10-24 Stepan Kasal <kasal@ucw.cz>
8309 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
8311 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8313 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8314 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8315 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8316 reported by Nelson H. F. Beebe for Coreutils 6.4.
8318 * tests/tools.at (autoconf --trace: user macros): Remove test
8319 for tracing multiline macros, since m4 1.4.7a uses a different
8320 way to number lines. Problem reported by Ralf Wildenhues.
8322 2006-10-24 Stepan Kasal <kasal@ucw.cz>
8324 * bin/autom4te.in (handle_m4): Do not redirect stdin to
8325 /dev/null since the heuristics for interactive behaviour was
8328 * bin/autom4te.in: With --force, always refresh the output
8329 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
8331 * bin/autoconf.as: Fix the verbose message at the end.
8333 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>
8335 * configure.ac (AC_INIT): Bump to 2.60c.
8338 2006-10-22 Paul Eggert <eggert@cs.ucla.edu>
8340 * NEWS: Version 2.60b.

8343 2006-10-15 Karl Berry <karl@gnu.org>
8344 * build-aux/texinfo.tex: automake 1.10
8346 * NEWS: Remove AC_CACHE_CHECK_INT.
8347 * doc/autoconf.texi (Caching Results): Likewise.

8398 (Imported from Automake.)
8399 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8400 which incorrectly sets the mode of an existing destination
8401 directory. In some cases the unpatched install-sh could do the
8402 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8403 system. We hope this is rare in practice, but it's clearly worth
8404 fixing. Problem reported by Alex Unleashed in
8405 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8406 Also, don't bother to check for -m bugs unless we're using -m;
8407 suggested by Stepan Kasal.

8461 include the default headers, and redefine obstack_chunk_alloc
8462 and obstack_chunk_free. Fixes false failure with glibc.

8484 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8485 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8486 Use a better substitute, by inspecting the output of "ls"
8487 rather than just using ":".
8488 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8489 rather than AS_EXECUTABLE_P, since we needn't worry about
8490 non-regular files here.
8492 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8493 due to configuration hassles with this. See Tonya Underwood's report

8505 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
8506 initialization which is not inherited through the environment
8507 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8508 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8517 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8518 comment about ac_cpp_err; it was incorrect, and anyway
8519 ac_cpp_err is being removed below.
8520 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8521 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8522 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8524 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8525 with werror_flag and conftest.err and so forth. This is more
8526 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8527 and anyway the user shouldn't normally want to see this gorp logged.
8528 Problem reported by Ralf Wildenhues.
8529 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8530 empty, not 'no', since the rest of the code uses 'test -z'.
8532 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
8534 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8535 Use a single call to AC_DO_TOKENS rather than multiple, for
8537 (_AC_LINK_IFELSE): Test that resulting file is executable.
8538 Problem reported by mwoehlke in
8539 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8541 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8542 than creating a file to use with test -x; this is much faster.
8544 2006-10-02 Bruno Haible <bruno@clisp.org>
8546 * lib/autom4te.in (Automake-preselections): Add
8547 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8549 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8551 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
8552 standard error, `experr' should be used, not `expout'.

8556 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
8557 fseeko testing program twice; just use the earlier result.
8558 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8559 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8560 still doesn't let the program compile.
8561 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8564 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8565 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8566 include it, without including anything else.
8567 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8569 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8573 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
8574 `error.h', and include it, for a `error_at_line' prototype.
8575 Use a nonempty format string in the link test.
8576 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
8577 for a declaration of wait3.

8583 can apply to constants too, and that it checks for macro defns.
8584 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

8586 values. Problem reported by Ralf Wildenhues.

8801 broken lex libraries like native ia64-hp-hpux11.22; see
8802 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

8931 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8932 -Wundef -Werror". Problem reported by David Fang in
8933 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8956 problems with arg script text that doesn't end in newline, and

8993 less skeptical about "volatile", after discussion with
8994 Bruno Haible on bug-gnulib.
8995 (Limitations of Usual Tools): Warn about sed stripping
8996 leading white space from text. From Bruno Haible.

9000 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
9001 compiler complains about it, even if things works after the
9002 complaint. Problem reported by Peter O'Gorman.

9005 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

9008 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9010 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
9011 after -R regardless of host. Patrick Welche reports that this

9023 under AC_C_VOLATILE.
9024 (Volatile Objects): Be a little less skeptical about what
9025 "volatile" means. Derived from thoughts by Ben Pfaff in
9026 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
9028 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9032 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9034 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9035 more globally, since the 2006-06-30 patch didn't suffice. Problem
9036 reported by Keith Marshall. Also, don't bother with builddir2,
9037 since it shouldn't be needed any more.
9039 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9042 Document AC_COMPUTE_INT. Fix wrong statements on Default

9058 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9060 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9061 Require that long long int be at least 64 bits wide. C99 requires
9062 this and enough programs depend on it so we should check for it.
9063 Bruno Haible reports in
9064 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9065 that long long int is 32 bits wide with some nonstandard compilers.

9068 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
9070 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9071 to a nonexistent file, so that we don't have to worry about
9072 a local site configuration that doesn't use /usr/local.
9073 Problem reported by Keith Marshall in
9074 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9076 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9078 * doc/autoconf.texi: Be more consistent about using @acronym with
9079 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9080 quite right (it talked about "OSF/Tru64", even though the
9081 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9082 and it even mentioned "OSF 4"!) and at this point there's little
9083 reason to talk about OSF any more, since it died in 1994.
9084 (Specific Compiler Characteristics): Simplify example of
9085 negative-size array.
9086 (File Descriptors): Reorder to make the text flow better.
9087 Remove joke about "appreciate the various levels"; I didn't get it.
9088 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
9089 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9090 (File Descriptors, Limitations of Usual Tools):
9091 Tone down the advice against renaming or removing open files.
9092 (Limitations of Usual Tools): Add a new section, on 'rm'.
9094 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9096 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9097 -lXt in LIBS, idea from Karsten Hopp; this was due since
9100 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9101 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9102 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9103 (which belong to Xt, not X itself). See Debian bug 327655.
9105 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9107 * configure.ac (AC_INIT): Bump to 2.60a.

9118 * config/texinfo.tex: Sync from upstream.
9120 * bin/autom4te.in (handle_traces): Transform the `@S|@'
9121 quadrigraph correctly in traces.
9123 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:

9127 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9129 * doc/autoconf.texi (Changed Directory Variables): New node,
9130 to document the whole `datarootdir' business a bit better.
9132 * tests/torture.at (datarootdir workaround): Extend test.
9133 Prompted by report by Alexandre Julliard.
9135 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9137 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9138 when using default mode of IBM C 6 for AIX. Problem and two-line
9139 fix reported by Larry Jones.
9141 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9144 about literal '${datarootdir}' if a definition is found in the
9147 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9149 * NEWS: Use "M4" rather than "m4" when appropriate.
9150 Problem reported by Eric Blake.
9151 * doc/autoconf.texi: Likewise.
9152 Use @acronym around BSD, GCC, and GNU when appropriate.
9153 (Why GNU M4): Renamed from "Why GNU m4".
9154 (Redefined M4 Macros): Mention that Posix
9155 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9156 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9159 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9161 * bin/autom4te.in (handle_output): Do not forbid the empty
9163 * tests/tools.at (autoconf: the empty token): New test.
9165 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9167 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9168 calls, so that we do not care whether they are LIFO or FIFO;
9169 in the m4_wrap, do not check which diversion is the topmost
9170 one, just check that the stack is balanced at the end.
9171 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9172 base diversion forever--pop the previous diversion before
9173 opening the new one; consequently, remove the m4_wrap call.
9174 * lib/autotest/general.m4 (AT_INIT): Likewise.
9175 * tests/m4sugar.at: Do not use
9176 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

9179 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9181 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9182 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9183 Rework example of m4wrap token-pasting trouble so that it doesn't
9184 care whether it's LIFO or FIFO.
9185 Fix some "contrary to"s that are awkward in English.
9187 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9189 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9190 to `yes' instead of `int$1_t' if the type is found, for more
9191 consistent configure output (where $1 is the number of bits).
9192 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9193 Suggested by Bruno Haible.
9195 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9196 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9197 with system headers. Report by Bruno Haible.
9199 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9201 * config/config.guess, config/config.sub: Sync from upstream.
9203 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9204 in order to avoid picking up an older installed frozen m4sh.m4f.
9205 Besides an outdated shell startup, this could have been created
9206 by an earlier M4 version with incompatible frozen file format.
9208 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9210 * README: Recommend m4 1.4.4 instead of 1.4.3..
9211 * doc/autoconf.texi: Likewise.
9212 (Special Chars in Names): Say that $(.FOO) is portable, as
9213 suggested by Stepan Kasal.
9214 (Installation Directory Variables, Build Directories):
9215 (Automatic Remaking, Subdirectories, Fortran Compiler):
9216 (Making testsuite Scripts, Defining Directories):
9217 Quote variable usages better.
9218 (Making testsuite Scripts): Add clean-local rule to makefile
9219 snippet, by Eric Blake.
9220 (Installation Directory Variables): Fix table item font.
9221 Reword slightly to clarify. Generalize advice about
9222 not using special characters to include all file-related
9223 vars, not just VPATH.
9224 (Special Chars in Variables): Warn about special characters in
9226 (Assignments): Clarify default-value example as suggested by
9228 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9229 (Special Shell Variables): Note leading ./ or ../, as suggested
9231 (Limitations of Builtins): Under cd, warn about CDPATH.
9232 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9235 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9237 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9238 `@var', for texi2html.
9239 (Systemology): Some more word wrapping, for DVI output.
9240 (autom4te Invocation): The short option for `--melt' is `-M',
9243 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9245 * doc/autoconf.texi: More formatting and English tweaks,
9246 many suggested by Ralf Wildenhues.
9247 Reword to avoid "@code{...}'s" and the like, since it's ugly
9248 with Emacs info mode. discontents -> woes.
9249 Put a few "will"s back. time stamp -> timestamp.
9250 side-effect -> side effect.
9252 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9254 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9255 Warn about $@ not persisting. Problem reported by Julien Danjou in
9256 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9257 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9258 Mention other special chars, too.
9260 2006-06-14 Eric Blake <ebb9@byu.net>
9262 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9264 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9266 * doc/autoconf.texi: Some systematic minor improvements, as
9267 follows. Use "makefile" when talking about makefiles
9268 generally (which might be named "makefile" or "Makefile" or even
9269 "foo.mk"), "Makefile" when talking about a specific makefile
9270 called "Makefile". This unclutters the text from weird quotes
9271 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9272 values" rather than "@var{foo}s" and similar constructs containing
9273 "}s". Use "Make rules" rather than "Makefile rules". Minor
9274 English-language improvements. Change the prefix "sub-" to "sub"
9276 Put blank lines around examples more consistently.
9277 Avoid "rather" and "very" as intensifiers.
9278 Avoid "will" as an auxiliary.
9279 (Limitations of Make): Split this node into....
9280 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9281 (Leading _ in Macro Names, Backslash-Newline-Newline):
9282 (Backslash-Newline Comments, Long Lines in Makefiles):
9283 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9284 (obj/ and Make, make -k Status, VPATH and Make):
9285 (VPATH and Double-colon, $< in Explicit Rules):
9286 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9287 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9288 New nodes, resulting from splitup of Limitations of Make.
9289 All cross-references changed. Raise the top node from
9290 a section to a chapter, and all subnodes accordingly.
9291 Redo the introductory wording to match the new organization.
9292 (Installation Directory Variables): Use an example that is
9293 closer to what Autoconf actually does. Mention that VPATH's
9294 value should not contain metacharacters or white space.
9295 (Fortran Compiler): Fix a VPATH bug in an example.
9296 (Leading _ in Macro Names): Mention that this problem is no longer
9297 of practical concern.
9298 (VPATH and Make): Reword the advice to make it clearer
9299 that Autoconf and Automake support VPATH in non-GNU make, but
9300 many packages have bugs in this area.
9301 ($< in Explicit Rules): Refer to Build Directories rather
9302 than using a (non-VPATH-safe) example.
9303 (Automatic Rule Rewriting): Mention the sort of disaster that
9304 can ensue with Solaris-style rule rewriting with VPATH.
9306 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9308 * doc/install.texi (Compilers and Options): Weaken the
9309 suggestion to use GNU make for VPATH builds.
9311 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9312 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9314 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9315 in regular expression.

9319 * doc/autoconf.texi (Installation Directory Variables):
9320 Drop extra @samp from `@table @samp' item.
9321 (Limitations of Usual Tools): Comment fix.
9322 Do not nest @samp just to point to other table items.
9323 (Writing testsuite.at) <AT_CHECK>: The second argument to
9324 `@dvar' is already @samp'ed.
9325 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9326 do not use @var in the second argument.
9328 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9330 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9331 $as_shell.exe too. Problem reported by Andreas Buening in
9332 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9334 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9336 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9337 `unused variable' compiler warning, for `-Wall -Werror'.
9338 Reported by Jaap Haitsma in
9339 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9341 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9343 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9344 case the compiler dumps core. Problem reported for
9345 OpenServer 5.0.7 by Tim Rice in
9346 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

9350 2006-06-06 Tim Rice <tim@multitalents.net>.
9352 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9353 "ERROR" only shows up in "make check" output if there is an

9377 * config/texinfo.tex: Sync from upstream.
9379 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9380 seen, invoke libtoolize with `--ltdl' argument.
9381 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9383 Suggested by Eric Blake.
9385 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

9397 * doc/autoconf.texi: Modernize some of the references to Solaris.
9399 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9401 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9402 message issued by AC_REQUIRE.
9403 * tests/m4sugar.at: Check m4_require's error message.
9404 * tests/base.at: Check AC_REQUIRE's error message.
9405 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9407 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9409 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9410 `expout' as the last parameter.
9411 * tests/tools.at: Adapt to the above change.
9413 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9415 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9416 information about race-free implementations of mkdir.

9425 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9427 * NEWS: GNU make now recommended for VPATH builds.
9428 Mention that some macros are now documented to be obsolescent.
9429 * doc/autoconf.texi:
9430 Prefer "current" to "modern" to describe
9431 currently-used (albeit perhaps old-fashioned) hosts.
9432 Mention which ancient features no longer need to be worried about.
9433 setgid -> set-group-ID
9434 setuid -> set-user-ID (these are the Posix terms)
9435 Fix some misuses of "only".

9446 (Installation Directory Variables): shall -> should
9447 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9448 Mention that it's now safe to use 3 and 4.
9449 (Limitations of Usual Tools): cp -r is now specified by Posix.
9450 Omit longwinded and obsolescent discussion of cp -f.
9451 Modernize discussion of expr, ls.
9452 (Limitations of Make): Modernize discussion of VPATH builds.
9453 Mention $? as a workaround in some cases.
9454 * doc/install.texi (Basic Installation):
9455 Mention "./configure; make; make install" first. Be more
9456 specific about why this file is generic. Remove unnecessary
9457 parens. Remove misleading "only". Remove obsolete advice
9458 about csh. Don't say "configure" takes awhile; say it
9459 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9460 and CC=c99 rather than CC=c89, as these are blessed by current
9461 Posix. Recommend GNU make if doing a VPATH build.
9463 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9465 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9466 examples involving shell prompts.

9469 and Paul Eggert <eggert@cs.ucla.edu>
9471 * doc/autoconf.texi (Here-Documents): Add details about the
9472 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9473 use "here-documents" instead of "here documents".
9475 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9477 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

9482 anywhere in directory names.
9484 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9486 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9487 about quoting the case statement, just in case.
9488 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9489 was fixed in ksh93g; reported by Ralf Wildenhues.

9503 argument with leading hyphen. Problem reported by Paul Eggert.
9505 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9507 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9508 about quoting ac_try: quote all of it, if any of it seems suspicious.
9509 This means we don't have to worry about ${ or sed any more.
9510 Also, double-quote the case statement, to work around misuses via
9511 underquoting as reported by Ralf Wildenhues in
9512 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

9528 Problem reported by Ralf Wildenhues in
9529 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9530 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9531 pre-2006-05-26 definitions, but leave in the comments that
9532 these macros are dangerous and should not be used.
9533 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9534 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9535 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9536 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.

9539 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9541 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9542 the use of 'tr', since this is our only use of 'tr'.
9544 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9545 and Paul Eggert <eggert@cs.ucla.edu>
9547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

9550 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9552 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9553 the output file in the `${datarootdir}' test.
9555 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9556 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9558 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9559 mention of `datarootdir' in the input file(s), but literal
9560 `${datarootdir}' in the output file, and we haven't warned yet,
9561 then warn as well: the user may have (erroneously) used
9562 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9563 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9564 * tests/torture.at (datarootdir workaround): Extend this test.

9568 and Paul Eggert <eggert@cs.ucla.edu>
9570 * doc/autoconf.texi (autoheader Invocation): The first argument to
9571 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9572 alternatives and clear up the language a bit.
9574 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9576 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9577 ac_config_guess, ac_config_sub, ac_configure.
9578 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9579 Fix typo that prevented an unnecessary space from being removed.
9580 Problems reported by Ralf Wildenhues in:
9581 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9583 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9585 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9586 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9587 Don't use the term "thread-safe" to talk about mkdir race
9588 conditions, since the problem is more a process than a thread
9589 issue. Problem reported by Stepan Kasal in:
9590 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9591 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9592 the test for 'install' more closely. Look at MKDIR_P first.
9593 Look in the PATH, and at /opt/sfw/bin.
9594 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9595 Don't bother to try mkdir -p, since we already check mkdir --version;
9596 just look at the version number. (There's no easy way to check
9597 for race-free implementations.)
9598 * tests/tools.at (autoconf: subdirectories): Adjust to above
9599 changes, since MKDIR_P now might end in "/mkdir -p".
9601 * doc/autoconf.texi (autoheader Invocation): Mention that the
9602 first arg of AC_DEFINE_UNQUOTED must be a literal.
9603 Problem reported by Ben Pfaff in
9604 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9606 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9607 * doc/autoconf.texi (Special Chars in Variables): New section.
9608 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9609 (Installation Directory Variables): Quote $(datadir) better.
9610 (Limitations of Builtins): Describe some of eval's trickiness.
9612 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9613 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9615 in front of every arg, not just trailing args. Quote apostrophes.
9616 (_AC_EVAL_ECHO): New macro.
9617 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9618 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9620 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9621 exposed by quoting of eval argument. Put the command on line line
9623 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9624 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9625 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9626 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9627 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9628 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9629 Use eval more safely.
9630 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9631 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9633 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9634 lines, exposed by quoting of eval argument.
9636 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9637 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9639 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9640 initialization of `ac_cv_exeext', do not override it if it was
9641 already set, unless it was set to `no', for compatibility with
9642 Autoconf-2.13, and comment this.
9643 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9644 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9645 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9646 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9647 Document that this test may be overridden by setting
9650 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9652 Revert these two patches:
9654 2006-04-06 Eric Blake <ebb9@byu.net>
9655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9656 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9659 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9660 Clean up _AC_COMPILER_EXEEXT* macros.
9661 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9662 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9663 ac_file to the name of the default output file and call
9664 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9665 initial `rm' of the candidate files...
9666 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9667 the same list in subsequent `rm' calls, and for the temporary
9668 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9669 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9670 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9671 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9672 no longer needed) by libtool. Make it a cache check.
9673 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9674 copied here by mistake.
9675 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9676 _AC_COMPILER_EXEEXT.
9677 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9678 _AC_COMPILER_OBJEXT directly.
9679 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9681 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9683 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9684 Fix description of how the buggy `sed' works.
9686 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9690 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9691 ENOLCK. Only mention `make -j' when applicable. Only raise
9692 fatal errors when `make -j' is involved. Improve error message.
9694 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9696 * doc/autoconf.texi (Here-Documents): We now know more about
9697 the variable expansion in here documents bug.
9698 Thanks to Tim Rice and Stepan Kasal.
9700 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9701 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9703 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9705 * tests/autotest.at (Multiline command from M4 expansion):
9706 No failure to be expected if the shell quotes newlines in
9707 commands in the `set -x' output. Report by Tim Rice.
9710 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9712 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9713 expansion in the here-documents used by config.status, as that
9714 runs afoul of the Korn shell version M-12/28/93d bug described in
9715 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9716 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9717 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9719 2006-05-23 Jim Meyering <jim@meyering.net>
9721 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9722 Fix typo introduced with 2006-04-02 change. It reversed the sense
9725 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9727 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9728 ac_dB slightly, to save bytes in the script.
9729 Max out at 50 lines, rather than 96; this is more likely
9730 (though not guaranteed) to avoid obscure 'sed' failures.

9734 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9735 `tr -d -' as bad option argument. Work around this by deleting
9736 an unrelated character.
9737 Report by Tim Rice <tim@multitalents.net>.
9739 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9740 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9741 Stepan Kasal <kasal@ucw.cz>
9743 * doc/autoconf.texi (Particular Programs): Do not promise that
9744 we always prefer the GNU version of the program, and that we
9745 search according to PATH; both rules can have exceptions.
9746 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9747 AC_PROG_SED. Move descriptions of limitations
9748 to the Limitations of Usual Tools section.
9749 (Limitations of Usual Tools) <sed>: Mention script length
9750 limitations with Solaris /usr/ucb/sed.
9751 <grep>: Fix wording for empty alternative. Mention that -c and
9752 -l should not be combined, and that -E and -F should not be
9755 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9756 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9758 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9759 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9761 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9763 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9764 AC_DEFINE is now passed to m4_pattern_allow.
9765 * NEWS: Mention that; likewise for AC_SUBST.
9766 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9767 the parameter to m4_pattern_allow.
9768 * tests/tools.at: Add a check for that.
9770 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9772 * lib/autoconf/status.m4: Fix typos.
9774 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9776 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9777 only the files that this macro generates.
9779 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9781 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9782 the HP-UX sed limitation of 99 commands, labels do not count.
9783 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9785 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9787 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9789 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9790 Import the following fix from coreutils:
9792 2006-01-13 Jim Meyering <jim@meyering.net>
9794 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9795 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9796 not double-quote uses of that variable, to accommodate the rare
9797 case in which getmntent is available in none of the libraries
9798 checked. This happens at least on FreeBSD 5.0.
9800 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9802 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9803 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9804 some other programs unwisely rely on these undocumented vars.
9805 But put in warning comments about them.
9806 Problem reported by Ralf Wildenhues in
9807 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9808 * NEWS: Document that these variables are intended to go away.
9810 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9812 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9813 and set the language to C++ (analogous to the equivalent Fortran
9816 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9817 * doc/autoconf.texi (C++ Compiler): Document it.
9818 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9821 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9823 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9824 that caused config.status to generate 100-command sed scripts; the
9825 portable limit is 99.
9827 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9829 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9830 variable `ac_d' instead of `d' to avoid infringing namespace.
9831 Report by Ralf Menzel.
9833 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9835 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9836 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9837 * tests/tools.at (autoconf: subdirectories): New test, taken from
9838 the corresponding problem report by Ralf Wildenhues in:
9839 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9841 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9842 Quote some uses of shell variables if they might suffer unexpected
9843 globbing. This doesn't fix all instances of quoting problems that
9844 I found, just the easy ones that look safe.
9845 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9846 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9847 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9848 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9849 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
9850 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9851 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
9853 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.

9856 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9858 * bin/autoreconf.in ($help): Reword according to the manual.
9859 Suggested by Olly Betts.
9861 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9862 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9864 * bin/autoreconf.in: Pass the directory argument to
9865 `require_configure_ac'. Fix comment.
9866 * tests/torture.at (Configuring subdirectories): Expose this.
9867 Reported by Olly Betts.
9869 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9871 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9872 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9873 Automake as follows:
9875 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9876 `$configure_in' instead of `configure.in', to preserve
9877 directory component.
9879 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9881 * config/config.guess, config/config.sub, config/texinfo.tex,
9882 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9884 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9886 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9887 test for C99 conformance; (bool) 0.5 is an integer constant
9888 expression, but (bool) -0.5 is not. Problem reported by Fedor
9889 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9891 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9893 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9894 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9895 Warn about obsolete install-sh files. Remove stray sentence
9896 fragment and fix cross reference.
9897 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9898 install -d; this undoes the 2006-05-10 change.
9899 (MKDIR_P): Mark with AN_MAKEVAR.
9900 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9901 that we don't require $INSTALL to be thread-safe. Move comments
9902 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9903 of AC_PROG_INSTALL. Output a message saying that we're checking
9904 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9905 MKDIR_P instead of AC_SUBST.
9906 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9907 Special magic for MKDIR_P, too.
9908 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9910 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9912 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9914 Sync from Automake, as follows:
9916 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9917 * config/install-sh: Initialize IFS, so field splitting isn't
9919 * config/mkinstalldirs: Likewise.
9920 * config/missing: Remove superfluous quotes. Replace all uses of
9921 `[' by `test', for consistency, and for..
9922 * config/missing (sed_minuso, sed_output): New variables.
9923 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9924 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9925 Fixes `missing' to detect `--output' for help2man. Fixes
9926 PR automake/483. Report by Dennis J. Linse.
9927 (autom4te): Document in `missing --help'.
9929 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9931 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9932 * config/install-sh: Don't use 'path' to talk about file names,
9933 as per GNU coding standards. Close a race condition reported by Ralf
9934 Wildenhues and Stepan Kasal. There is still a race condition
9935 on hosts that predate Posix 1003.1-1992, but we can't help this.
9936 Don't mishandle weird characters like space on pre-Posix hosts.
9937 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9938 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9939 AC_PROG_MKDIR_P from AS_MKDIR_P.
9940 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9941 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9942 earlier editions are not (including Automake 1.8.3).
9943 Do not suggest mkinstalldirs for thread-safety.
9944 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9945 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9946 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9947 presence of special characters and race conditions.
9948 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9949 in Autoconf's name space.
9951 2006-05-10 Bruno Haible <bruno@clisp.org>
9952 and Paul Eggert <eggert@cs.ucla.edu>
9954 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9955 from Automake with minor changes.

9958 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9960 * config/install-sh: Update to Automake CVS version, as follows:
9961 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9962 * lib/install-sh: Simplify the expr implementation of dirname.
9963 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9964 * lib/install-sh: Handle --, and diagnose unknown options.
9966 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9968 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9969 `./autom4te' to create `./testsuite', since the `all' target
9970 will ensure its presence, but `installcheck' should not create
9971 the uninstalled wrappers.
9973 * tests/torture.at (Unusual Automake input files): Skip if we
9974 detect automake < 1.8.
9976 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9978 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9979 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9980 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9983 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9985 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9986 munge (multiple) white space and other oddities.
9987 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9988 single quotes in variable assignment.
9989 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9990 and similar failures by adding multiple spaces, tabs, and other
9992 Report and different test suggested by Francesco Romani
9993 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9995 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9996 single quotes, we only need to search for single quotes; this
9997 both simplifies the search pattern, and makes us less
9998 susceptible to `echo' variations for arguments not containing
10000 (_AC_ARG_VAR_VALIDATE): Likewise.
10002 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10004 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10005 `$*' and IFS concatenation issue with traditional shells and

10010 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10011 precisely which Mac OS X versions have the od problem.
10013 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10015 * doc/autoconf.texi: Use @option systematically.
10017 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10018 and Bruno Haible <bruno@clisp.org>
10020 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10022 (Integer Overflow): Mention the special case of integer division
10025 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10027 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10028 traditional shells like the Solaris one that do not use the
10029 first IFS character for assembling `$*'.
10030 Prompted by a related report from autoconf_bug@nro.ca.
10032 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10033 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10035 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10036 Mention more problems with the -e option.

10041 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10043 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10044 in URLs to improve DVI formatted output (requires texinfo 4.6).
10045 (System Services, Systemology, Shellology): Likewise.
10046 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10049 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10051 (Runtime): Fix macro argument names to match description:
10052 `action-if-found' -> `action-if-true' and similarly.
10053 (Obsolete Macros): Likewise.
10054 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10055 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10056 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10058 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10060 * doc/autoconf.texi (Limitations of Make): Clean up markup.

10076 (Integer Overflow, Null Pointers, Buffer Overruns):
10077 (Floating Point Portability, Exiting Portably): New sections.
10078 (Writing Test Programs): Fix some langauge. Recommend exiting
10079 with status 1, not merely nonzero. Clarify exit declaration.
10080 (Run Time): Move C exit status stuff to new Exiting Portably section.

10090 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10091 since as_me isn't set yet.
10093 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10095 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10096 a few minor bugs in this area.
10098 * doc/autoconf.texi (Programming in M4sh): Comment out the
10099 documentation of AS_BASENAME, for now.
10100 (Shell Substitutions): Do not use AS_DIRNAME in an example.

10138 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10140 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10141 newline from the `trap' code to finish `config.log'; the NetBSD
10142 /bin/sh resets the exit status after an empty command, as
10143 documented in doc/autoconf.texi.
10144 Reported by Dalibor Topic <robilad@kaffe.org>.
10146 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10148 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10149 Suggested by Bruno Haible.
10151 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10153 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10154 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10155 Instead, just list the shells that we know work.
10156 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10157 changed. Be more cautious about the _cv_ variable.
10158 * tests/tools.at (Syntax of the shell scripts): Check the
10159 _cv_ variable once, at first, to avoid an internal autoconf error
10160 when sh -n does not work.
10162 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10164 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10166 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10168 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10169 use ">&-" since we're only 99.999% sure that this is portable,
10170 and since the MinGW bug is fixed in a different way.
10171 * lib/autotest/general.m4 (AT_INIT): Likewise.
10173 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10175 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10176 before opening config.log, to avoid hitting a bug on MinGW.
10178 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10180 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10181 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10182 This works around a MinGW bug reported by Eric Paire.
10183 Make sure that all writes to the log file append to it,
10184 rather than possibly losing data.
10185 * lib/autotest/general.m4 (AT_INIT): Likewise.
10187 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10189 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10192 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10196 * configure.ac (AC_INIT): Bump to 2.59d.
10198 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10202 * Makefile.maint (news-date-check): Do not require a leading `*'
10203 before the release date in NEWS.
10205 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10206 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10208 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10209 the instantiated file do not contain the string 'datarootdir'
10210 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10211 @mandir@, replace the reference '${datarootdir}' by the value.
10212 * tests/torture.at (datarootdir workaround): New test.
10213 * NEWS: Advertise this temporary fixup.
10214 Based on a patch by Bruno Haible, reported and analyzed by
10215 Paul Eggert and Noah Misch.
10217 2006-04-12 Eric Blake <ebb9@byu.net>
10219 * tests/autotest.at (Debugging a failed test): Fix comment.
10221 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10223 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10224 all the changes since 2006-04-07.
10226 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10228 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10229 succeeded, but `ln -s file dir' failed, take care to remove the
10230 leftover target before the next test, to prevent its spurious
10231 failure; also make sure `ln file dir' works before selecting it.
10232 Thanks to Keith Marshall for pointing this out.
10235 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10236 assignments in `at_debug_args', so that we put them correctly
10237 in the `run' script.
10238 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10239 Reported by Eric Blake.
10241 2006-04-11 Eric Blake <ebb9@byu.net>
10243 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10244 top-level tests after micro-suite has been run. Used in...
10245 (Debugging a successful test, Debugging script and environment),
10246 (Debugging a failed test): ...these new tests. The first of these
10248 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10249 macro, split out from...
10250 (AT_INIT): ...here, so that using -d also generates a run script.
10251 Document that -d inhibits top-level logging.
10252 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10253 inhibits top-level logging; debug scripts are created.
10255 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10257 * tests/autotest.at (Empty test, Empty check): New test to check it.
10259 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10262 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10264 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10265 the files if a problem appears. Make the empty *.at files
10266 read-only, too. Proposed by Ralf Wildenhues.
10268 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10270 * config/Makefile.am: Add comment to force updated Makefile.in.
10272 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10273 space only patch to this file, this patch causes the Makefile.in
10274 files that include freeze.mk to be updated, and thus have a
10275 newer time stamp again, which in turn makes a pristine CVS
10276 checkout have correct time stamps.
10278 * Makefile.maint (cvs-sv): New macro, to be used..
10279 (config.guess-url_prefix, config.sub-url_prefix)
10280 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10281 point to CVS text checkout of Gnulib files.
10282 (copyright-check): Bump current year.
10283 (announcement): Do not hard-wire `./announce-gen'.
10284 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10286 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10288 (wget_files): Update config.guess, config.sub, texinfo.tex by
10289 `wget-update', now that their URLs work again.
10291 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10293 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10294 Problem noted by Paul D. Smith.
10296 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10298 * doc/autoconf.texi: Remove unused words from word list.
10299 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10300 .x-sc_trailing_space: New files.
10302 * doc/standards.texi: Sync from gnulib.
10304 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10305 `LIBOBJDIR' as experimental.
10307 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10308 with a target directory; it's internally implemented as `cp'
10309 anyway, but since Autoconf advertises the possibility to use
10310 a target directory when LN_S is `ln -s', we need to find out.
10311 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10312 analyzed by Keith Marshall <keith.marshall@total.com>.
10316 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10318 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10319 confdefs.h as-is. In general, if it has backslash-newline or the
10320 like, then it doesn't work either to sort or to remove empty
10323 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10325 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10327 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10329 * lib/autom4te.in (Automake-preselections): Preselect
10332 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10334 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10335 apostrophe within a single-quoted string, as this is the usual
10336 tradition and is easier to read than '"'"'. Don't rely on the
10337 shell treating "$/" like '$/'. Use a more-consistent indenting
10338 style for the trap.
10340 2006-04-09 Eric Blake <ebb9@byu.net>
10342 * tests/autotest.at (Backquote command substitution),
10343 (Multiline backquote command substitution): Remove mistaken
10344 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10346 (Parenthetical command substitution, Multiline parenthetical
10347 command substitution): here.
10349 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10351 Import macros from gnulib (often changing their name).

10379 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10380 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10381 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10382 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10383 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10384 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10385 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10386 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10387 (Coding Style). Don't mention m4_expand_once.
10388 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10398 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10399 Catch a bug in an HP-UX C compiler.
10400 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

10408 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10409 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10411 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10413 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10414 of the warning introduced by the 2001-08-28 change.
10416 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10417 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10419 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10420 variables shall be overriden by the cache.
10421 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10422 that contains braces.
10424 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10426 Revert the patch from 2006-04-01 and only improve
10427 _AS_DETECT_BETTER_SHELL:
10429 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10430 skip nonexistent directories.
10431 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10432 only shell candidates which exist.
10433 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10434 * lib/autotest/general.m4 (AT_INIT): No need to give three
10435 parameters to _AS_PATH_WALK.
10437 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
10438 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10440 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
10441 distinguish m4sugar macros.
10442 * tests/tools.at (autoupdating with aclocal and m4_include):
10443 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10444 test case by Noah Misch <noah@cs.caltech.edu>.
10446 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10448 Revert my change from 2006-03-17, in other words:
10449 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10451 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
10452 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
10455 2006-04-07 Eric Blake <ebb9@byu.net>
10457 * doc/autoconf.texi (Programming in M4sh): Document that
10458 AS_MKDIR_P exits the script on failure.
10459 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10461 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10463 * config/elisp-comp, config/install-sh, config/mdate-sh,
10464 config/missing, config/mkinstalldirs: Sync from Automake.
10466 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
10469 * doc/make-stds.texi: Sync from gnulib.
10471 2006-04-06 Eric Blake <ebb9@byu.net>
10473 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10474 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10477 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
10478 Eric Blake <ebb9@byu.net>,
10479 Paul Eggert <eggert@cs.ucla.edu>,
10480 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10482 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10483 whether `set' quotes correctly: redirect stderr of the tested
10484 `set', and use a subshell, for Ultrix; use `sed' instead of
10485 `grep' for zsh `set' which may write binary output; match only
10486 at the beginning of a line, to avoid false positives.
10487 In order to avoid false positives by unrelated variables with
10488 multiline content, put the dump algorithm in a subshell and
10489 unset all variables containing newlines (except some which are
10490 special to the shell). Warn about cache variables that are
10493 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10495 * config/config.guess, config/config.sub, config/texinfo.tex:
10496 Sync from upstream.
10498 * tests/mktests.sh: Reword comments.
10500 * tests/mktests.sh: Only skip internal macros starting with
10501 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10502 Update exclusion lists for the test suite to this end:
10503 (AC_ARG_VAR): Do test this now.
10504 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
10505 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
10506 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
10507 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
10509 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
10510 shell issue with double-quoted command substitutions of native
10512 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
10515 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

10523 (sc_tight_scope): Do not fail for non-existing `src' directory.
10524 (sc_changelog): Skip the Copyright footer.
10525 * lib/autoconf/lang.m4: Remove trailing space.
10527 * lib/autoconf/status.m4: More replacements to
10528 <tab><space> where this makes sense.
10530 2006-04-06 Stepan Kasal <kasal@ucw.cz>
10532 * tests/Makefile.am (maintainer-check-posix):
10533 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
10535 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
10536 ac_config_<foo>s again, sometimes normalized, sometimes not.
10537 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10538 (AC_CONFIG_COMMANDS): Do not do so here.
10539 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10540 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10541 2005-07-25 rewrite. Noticed by Noah Misch.
10543 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
10544 _AC_PRESERVE_HELP_ORDER, ...
10545 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
10547 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
10548 inside m4_expand_once; it is redundant.
10550 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
10551 for --help from Cygnus `configure.'
10553 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
10555 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
10556 on a patch proposed by Ralf Wildenhues.
10558 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10560 * lib/autoconf/status.m4: Replace <space>''<tab> with
10561 <tab><space> where this makes sense.
10563 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
10564 Noah Misch <noah@cs.caltech.edu>
10566 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
10567 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
10568 * doc/autoconf.texi (Help Formatting): New node.
10569 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
10571 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10573 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
10574 lib/autoconf/specific.m4, lib/autoconf/status.m4,
10575 lib/autoconf/types.m4, lib/autotest/general.m4,
10576 tests/mktests.sh, tests/torture.at: White space cleanup:
10577 remove some SPACE before TAB, or add quoting ('' or @&t@).
10579 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
10581 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
10583 2006-04-05 Eric Blake <ebb9@byu.net>
10585 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
10586 empty test suite works.
10587 * tests/autotest.at (Empty test suite): Remove xfail.
10589 2006-04-05 Noah Misch <noah@cs.caltech.edu>
10591 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
10592 TAGS to ac_config_<foo>s.
10593 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
10594 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
10595 normalizing it, consistent it with previous releases.
10596 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10598 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10600 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
10601 Use simplified args that Eric Blake originally suggested.
10603 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
10605 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10606 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10607 Use 'comm' rather than N instances of grep; this also fixes a bug
10608 whereby substrings were incorrectly matched, causing us to not
10609 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10610 (exclude_list): Exclude empty macros.
10611 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
10613 Use awk rather than grep -E or egrep, to avoid
10614 portability problems with regular expressions containing newlines.
10615 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
10616 Switch from grep to awk syntax.
10617 (ac_exclude_script): Renamed from ac_exclude_egrep.

11537 suggested by Ben Elliston. Handle weird characters correctly.
11539 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11541 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11542 calls, so that the final expansion of this macro is shorter.
11543 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11544 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11545 the cleanup there. Use AS_VAR_* macros, to be more general.
11546 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11548 * lib/autoconf/general.m4: Use AS_IF where appropriate.

11573 "if $undefined_var;" succeeds with my shell.
11575 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11576 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11577 but change the m4_divert_text to m4_divert_once.
11579 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11581 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11582 Work around bug in Solaris /usr/xpg4/bin/awk.
11583 The bug is present in at least Solaris 8 through 10.
11585 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11587 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11588 some evil values and relying on the fact that $* concatenates the
11589 parameters by the first character from IFS.
11591 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11592 Stepan Kasal <kasal@ucw.cz>

11595 first header appears, define AH_HEADER.
11596 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11597 Update limitations about when to call AC_CONFIG_HEADERS.
11598 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11599 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11600 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11601 ``Configuration Actions''; fix their index entries.
11603 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11604 options correctly. Process N-M as M-N if M is smaller than N.
11605 Process ranges correctly so that N-N will run only N.
11606 Sort and uniquify the tests that will be run. If there is more
11607 than one test, reinsert the banners for the tests.

11613 before passing the macro name to AH_TEMPLATE.
11615 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

11638 When building in place, set srcdir="."; suggested by Tim Van Holder.
11640 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11641 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11642 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11643 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11644 does not mean "no --srcdir option".
11646 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11648 * tests/autoscan.at (autoscan): New file.
11649 * tests/suite.at: Use it.

11655 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11657 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11658 add "2>&1"; gzip 1.2.4 prints help on stderr.
11660 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11662 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11663 was pushdef'ed twice while popped only once. Push it only once.

11675 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11676 "<tab>" in comment, so that the point is understandable.
11678 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11680 Rewrite substantial part of lib/autoconf/status.m4.
11681 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11682 and CONFIG_COMMANDS are not processed in four separate loops.
11683 Instead, there is one main loop. This alows that the common code
11684 is expanded only once, thus config.status (and configure) is smaller.
11686 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11687 the AC_LIST_FILES and cousins macros are no longer used.
11689 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11690 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11691 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11692 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11693 contain the initialization, nor the for loop, nor the associated
11694 commands; all these go to ...
11695 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11696 _AC_OUTPUT_CONFIG_STATUS.
11697 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11698 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11699 (_AC_OUTPUT_FILE): The creation of the sed script ...
11700 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11701 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11702 _AC_OUTPUT_MAIN_LOOP.
11703 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11704 _AC_CONFIG_COMMANDS): Use ...
11705 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11706 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11707 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11708 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11709 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11710 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11712 (_AC_CONFIG_UNIQUE): Update.
11713 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11714 Replaced by this ...
11715 (_AC_LIST_TAGS): ... new common macro.
11716 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11717 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11718 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11719 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11720 this didn't belong to the `config commands' section.
11721 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11722 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11723 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11724 to the `config commands' section either.
11725 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11726 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11728 ... and many changes to the comments nearby.
11730 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11731 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11732 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11733 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11734 (#define header templates): The comment at the top of the generated
11735 header now includes the name(s) of the source file(s).
11737 Several unrelated small changes:
11739 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11740 parameter to AC_DIAGNOSE.
11741 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11742 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11743 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11744 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11745 with AU::AC_OUTPUT.
11746 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11747 in AC_OUTPUT doesn't double-quote it either.
11748 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11751 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11753 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11754 versions of Portland Group compiler produce single- and double-quoted
11755 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11756 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11758 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11760 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11761 This is a corrected version of yesterday's patch.
11763 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11765 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11766 path, too; insert a "===" to emphasize the line.
11768 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11769 ac_cv_build_alias to ac_build_alias.
11770 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11772 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11773 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11774 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11775 (AC_ARG_VAR): ... here.
11776 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11779 Keep a list of all precious variables and process them with one simple
11780 for loop, instead of expanding all commands, or, OTOH, complicated
11781 processing of output of "set".
11782 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11783 variable names in new macro...
11784 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11785 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11786 a loop to assign all ac_env_* and ac_cv_env_* variables.
11787 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11789 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11790 its value to shell variable ac_precious_vars and call
11791 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11792 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11793 _AC_ARG_VAR_VALIDATE.
11795 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

11814 They are generated by the Tru64 v5.1B shell.
11816 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11818 Fix my changes from 2005-07-01; reported by Noah Misch.
11819 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11820 description, the macro now accepts only a single tag.
11821 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11823 Fix cases when the varsions of Autoconf and Autotest don't match.
11824 Reported by Noah Misch.
11825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11826 at_top_builddir, for compatibility with older autotest.
11827 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11828 is not set, use at_top_builddir, for compatibility with older
11829 versions of autoconf.
11831 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
11833 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11834 Problem reported by Patrick Welche.
11836 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11838 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11839 sed substitution command, so that we allow | in program prefixes
11840 and program suffixes. (& is a problem anyway; we're not fixing

11843 configure_input, top_builddir, srcdir, etc.
11844 * lib/autotest/general.m4 (AT_INIT): Likewise, for
11845 PATH_SEPARATOR in AUTOTEST_PATH.
11847 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11849 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11850 for loop over config.site files using `set', to allow
11851 directory names containing IFS characters.
11853 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11855 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11856 directories with weird names. Apparently some people like living
11857 on the edge. However, improve the test that "pwd" actually does
11858 report a name for the working directory.
11859 * NEWS: Remove the claim that we test for funny chars in dir names.
11861 2005-07-01 Stepan Kasal <kasal@ucw.cz>

11875 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
11877 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11878 document to output the default config_* lists to config.status.
11879 Don't recognize option --file, if the functionality is not there.
11880 Likewise for --header; moreover, recognize --he and --h as shortcuts
11881 for --help in that case.
11883 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11884 matches the order of execution. No code changed.
11886 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11888 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

11896 2005-06-29 Stepan Kasal <kasal@ucw.cz>
11898 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
11899 descriptors to child processes; reported by Norman Gray.

11903 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11905 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11906 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11907 (AC_SUBST): Call it.
11908 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11909 the directory specific variables; but don't call it for configure_input.
11911 2005-06-28 Derek Price <derek@ximbiot.com>
11913 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11916 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11918 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11919 directory have inherent problems with special characters like spaces,
11920 due to limitations in Make syntax. Problem reported by Alexandre
11922 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11923 Also, fix Tru64 porting problem with shell patterns,

11934 Fix some more shell quoting problems. Prompted by a bug report
11935 from Justace Clutter.
11936 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11937 variable into diagnostic. Make the diagnostic an error, not a warning,
11938 because we really don't support spaces and suchlike in dir names.
11939 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11940 Don't worry about backslashes in srcdir; it can't happen now.

11953 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11954 that '\|' is not allowed in BREs; recommend using newline separated
11955 list of patterns instead of multiple -e options.
11957 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11959 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11965 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11967 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11968 b, t, r, w commands require single space, while : cannot have any.
11969 (Special Shell Variables): Fix sed code this in the example.
11970 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11971 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11973 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11974 expand to the empty list. Don't use two pairs of m4_changequote,
11975 it's not necessary.
11977 2005-06-20 Derek Price <derek@ximbiot.com>
11979 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11981 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11983 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11984 * doc/autoconf.texi:
11985 Don't mention Solaris versions so much, if a
11986 problem is common to all extant versions of Solaris. Say "SunOS
11987 4" instead of "SunOS" for SunOS 4.
11988 (awk): Mention more of the limitations of traditional Awk.
11989 (cat): Don't talk about cat -v.
11991 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
11993 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
11994 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
11995 but the implementation is entirely different and is designed
11996 to be compatible with glibc strverscmp.
11997 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11999 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12000 on Mac OS X 10.4 reported by Peter O'Gorman in:
12001 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
12002 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12003 Use shell builtins rather than 'expr', to work around expr bug.
12005 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12007 * doc/autoconf.texi: "filesystem" -> "file system".
12008 "behaviour" -> "behavior".

12010 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12012 * lib/m4sugar/m4sh.m4: Likewise.
12013 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12014 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12016 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12017 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12018 to update the man page. That way, we don't have to check in new
12019 man pages every month.
12021 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12022 quotes and backslashes. Patch from Derek Price.

12031 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12032 -u, since it outputs chatter if the input files are the same.
12033 Problem reported by Ralf Menzel.
12035 2005-06-08 Derek Price <derek@ximbiot.com>
12037 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12038 renaming them since they are about to be redefined anyhow.
12040 2005-06-08 Derek Price <derek@ximbiot.com>
12042 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12043 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12044 Move m4_undefine to alphabetical order.
12046 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12048 * README: Recommend GNU M4 1.4.3 or later.
12049 * doc/autoconf.texi (Introduction): Likewise.
12050 Reword to avoid some formatting glitches.
12051 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12052 Clarify explanation of HP compiler bug.
12053 Redo example output tp match current CVS snapshot.
12054 Use @example.org in email addresses when the examples
12055 might get inadvertently cut-and-pasted into user code.
12056 Remove example of autom4te usage that doesn't seem to work now.
12057 Use modern AC_INIT (except when the example is meant to be
12058 shown with Autoconf 2.13).
12059 Update ksh info for Solaris 9 and later.
12061 Modernize description of Automake versions a bit.
12062 Don't claim a future version of Autoconf is near.
12063 * doc/install.texi: Reword to avoid some formatting glitches.
12065 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12067 * doc/autoconf.texi: Add [] to examples, so that the manual
12068 follows its own advice about quoting better.
12069 Reword to avoid some formatting glitches.
12070 * doc/installt.exi: Reword to avoid some formatting glitches.
12072 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12073 Tru64 ksh pattern matching bug. Reported against Libtool by
12074 Albert Chin <libtool@mlists.thewrittenword.com> and
12075 Nicolas Joly <njoly@pasteur.fr>.
12077 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12079 m4_cdr of one-member list was [[]] (one-member list containing an
12080 empty string) instead of [] (an empty list. Callers were skewed to
12081 match this misbehaviour. As a consequence of this:
12082 - m4_foreach([x], [], [foo]) expanded to `foo', while
12083 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12084 This bug has been fixed:
12086 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12087 expand to an empty string; print error msg if called without
12089 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12090 misbehaviour; handle [] and [[]] correctly.
12092 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12094 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12095 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12096 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12098 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12100 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12101 swallow records with more than 99 fields.
12102 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12103 parse the long line.
12105 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12107 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12108 swallow literals longer than 399. Reported by Ralf Wildenhues.
12109 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12110 to workaround this limitation.
12112 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12114 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12115 to gfortran, and make these the first two compiler names
12116 checked (following the general autoconf preference for gcc).
12118 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12120 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12121 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12122 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12124 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12126 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12127 expression of unbounded size when processing the --list
12128 option. This runs afoul of a limit of 399 bytes per regular
12129 expression on AIX. Problem reported by Ralf Wildenhues.
12131 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
12133 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
12134 * doc/autoconf.texi (Particular Headers): Reword example
12135 for multiline stdbool replacement.
12136 (Setting Output Variables): Reword text a bit. Don't
12137 give all the details about |#_!!_#|.
12138 Reword description of line replacement.
12140 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12143 now contain newlines, and substituted files must be referenced on
12144 a line alone; the sed scripts to substitute them are now very
12146 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12147 commands can be put in a sed script portably.
12148 * doc/autoconf.texi (Setting Output Variables): Document above
12149 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12150 use of multiline substitution.

12160 * tests/local.at: Don't attempt to check for negated character
12161 classes in shell scripts. The test was too brittle.
12163 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12165 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12166 * doc/autoconf.texi (Limitations of Builtins): Document this
12169 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12171 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12172 common code; used in many places in the tree.

12176 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12178 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12179 messages when ac_unique_file is not found.
12180 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12181 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12182 commands, for consistency with AC_MSG_ERROR and such.
12184 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12186 * bin/Makefile.am: Merge the two rules for creating scripts.

12194 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12196 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12197 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12198 (ac_top_builddir): ... this ...
12199 (ac_top_build_prefix): ... to this; the old name is also kept, for
12200 backward compatibility.
12201 (ac_top_builddir_sub): New variable, without the trailing slash,
12203 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12204 * doc/autoconf.texi (Configuration Actions): Rename
12205 ac_top_builddir to ac_top_build_prefix.
12206 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

12217 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12218 argument to m4_foreach. I guess it was necessary in the past,
12219 but I think it's a no-op now.
12221 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12223 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12224 ``cat <<_ACEOF'' commands to one.
12225 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12226 * lib/autoconf/status.m4: On various places, use expr instead of
12228 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12229 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12230 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12232 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12233 the wrong patterns between ``case'' and ``esac.'' The previous
12234 code had false positives.

12303 quoting rules. Problems noted by Stepan Kasal.
12304 Also, throughout this document, be more careful about white space.
12305 "blank", "white space", and "space" all have different meanings
12306 and we should be careful to say what we mean.
12308 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12310 Fix C++ related problems reported by Werner Lemberg.
12311 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

12345 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12346 by AC_DEFINE; it was a mistake.

12353 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12355 * doc/autoconf.texi (External Software): Quadrigraphs are not
12356 processed correctly in AS_HELP_STRING; avoid this in the examples.
12357 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12358 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12359 comment and reduce m4_default([foo], []) to [foo].
12360 (m4_strip): Update the explanation.
12362 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12364 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12365 Remove core.conftest.* too; it's generated by Tru64 5.1.
12366 Problem reported by Jennis Pruett.
12367 * lib/autoconf/functions.m4
12368 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12369 Don't bother to remove core files; AC_RUN_IFELSE should do that

12374 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12414 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12416 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12417 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12418 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12419 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12420 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

12424 * NEWS: The configure command now warns you if you attempt to use
12425 a directory whose name contains a special character like space,
12427 * doc/autoconf.texi (Installation Directory Variables): Allow
12428 "," in file names. Do not use \@; it's not a portable regexp.

12440 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12441 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12442 ac_pwd, and quote srcdir.
12443 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12445 * doc/autoconf.texi: Fix some systematic formatting problems.
12446 ".)" needs a following @: if not at the end of a sentence, and
12447 similarly for "!)". "etc." should be preceded by a comma.
12448 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12450 2005-03-22 Bruno Haible <bruno@clisp.org>
12452 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12453 argument is often called 'build-aux'.
12455 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12457 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12458 macro AC_TRY_LINK is obsolete.
12459 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12462 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12464 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12465 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12466 from a Common Lisp's `cl'.
12467 (AC_PROG_CXX): Behave according to the documentation: don't
12468 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12469 make the variable CCC precious; use `cl.exe', not `cl'.

12472 Alexandre Duret-Lutz <adl@gnu.org>
12474 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12475 /dev/null, as "configure" shouldn't read stdin, and this insulates
12476 us from problems (e.g., when testing for "cl"). Also, do this
12477 redirection before invoking "hostname" or "uname", and keep the
12478 original input stream available via...
12479 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12480 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

12490 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12492 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12493 newline if neither \c nor -n work, as that would output two
12494 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12496 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12498 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12499 This causes that any required macros inside will get before the if.
12500 * doc/autoconf.texi (autom4te.cache): A typo.
12502 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12504 Undo previous change, except keep the change to
12505 lib/autoconf/programs.m4 that replaced grep with shell
12506 pattern-matching. This is because net-snmp configure reads stdin.
12507 Reported by Noah Misch.
12509 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12511 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12512 from /dev/null, as "configure" shouldn't read stdin, and this
12513 insulates us from problems (e.g., when testing for "cl").
12514 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12515 before invoking "hostname" or "uname".
12516 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12517 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12518 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12519 "</dev/null" since it's now done at the top of 'configure'.
12520 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12521 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12522 Also, replace grep with shell pattern-matching, to save a process.

12526 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12527 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12528 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12531 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12533 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12534 grep -q isn't portable. Improve grep -s explanation.
12535 Problem reported by Dan Manthey.

12542 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12544 * doc/autoconf.texi: Use @acronym for DJGPP.
12545 Fix some @code's that should have been @env's, and vice versa.
12546 Sort environment variable names.
12547 Mention that shells no longer inherit IFS.
12548 Don't recommend PATH_SEPARATOR=';' so strongly.
12549 Mention that $RANDOM might expand to the empty string.
12550 "symlink" and "soft link" -> "symbolic link".
12551 Improve mktemp description (reported by Bruno Haible).

12589 CPPFLAGS to `configure' instead of setting it in `configure'.
12591 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

12627 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

12690 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12691 Update the long comment explaining it.
12693 m4_require no longer writes an ``is required by'' line to the
12694 execution stack. It contains only one bit of non-redundant
12695 information: that the macro was required, not called. And even
12696 this bit is useless in most situations: have you ever met a macro
12697 which both calls and requires the same macro?
12699 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12700 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12703 (m4_expansion_stack_pop): Remove the misplaced comment.
12704 (m4_require): Don't put the ``is required by'' line to the

12706 (_m4_divert_grow): New macro, counter for the temporary diversions.
12707 (_m4_require_call): Use it.
12708 * tests/m4sugar.at (m4_require): Expect output without the
12709 ``is required by'' messages.

12745 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12747 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12748 Warn about newline stripping in `` and $(). Update Solaris
12750 (Limitations of Builtins): Use expr "X...", not expr "x...", as
12751 X insulates us from future changes to Posix.
12752 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
12755 2005-01-19 Stepan Kasal <kasal@ucw.cz>

12800 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
12801 (_m4_divert_n_stack): New macro; the expansion is
12802 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
12804 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12805 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12806 stored in _m4_divert_diversion or _m4_divert_dump.
12807 (m4_divert_pop): When the parameter is given, compare the symbolic
12808 name with the last diversion pushed on the stack. Previously, the
12809 current diversion was compared with the numeric value of the
12810 diversion given as the parameter.
12811 (m4_require): If the macro hasn't been expanded yet, call ...
12812 (_m4_require_call): this new macro.

13119 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13120 "char c = '\200';" rather than "char c = 0x80;" as the

13299 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13301 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13302 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13303 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13304 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13306 More fixes to support spaces in the name of the build directory.
13307 This isn't a complete fix but it's an improvement.
13309 * bin/autoconf.as (autom4te_options): New var.
13310 Use it instead of appending to AUTOM4TE, so that we can allow
13311 spaces in the build directory's absolute name.
13312 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13313 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13314 AT_CHECK_NOESCAPE): Likewise.
13315 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13316 main program): Likewise.
13318 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
13320 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

13324 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
13326 * doc/autoconf.texi (Function Portability): Document isinf and
13327 and isnan. From a suggestion by Kevin Ryde.
13329 * lib/Autom4te/General.pm (END): Return correct exit status even
13330 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13332 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13334 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13335 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13336 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13338 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13340 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13341 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13342 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13343 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13344 * lib/autom4te.in (Automake-preselections): Preselect
13345 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13347 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13349 * lib/autom4te.in (Automake-preselections): Preselect
13350 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13353 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13355 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
13357 * doc/autoconf.texi (Shellology): Mention BIN_SH.
13358 Document problem with "`""`" in pdksh POSIX mode.
13360 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13362 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13363 with pdksh, too. Problem reported by Patrick Welche via
13365 * doc/autoconf.texi (Shellology): Note that set -o posix is
13366 useful for pkdsh, too.
13368 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13370 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13371 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13372 Don't fail if ENV or BASH_ENV is readonly.
13373 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13374 etc. are read only. Problem reported by Ludovic Courtes.
13376 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13378 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13379 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13382 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13384 * doc/autoconf.texi (File System Conventions): Warn about
13385 names like "aux". Problem reported by Eric Blake.
13387 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13388 by zero instead of array size, so that we can use any arithmetic
13389 constant expression (instead of requiring an integer constant
13390 expression). This allows us to test expressions like DBL_MAX <
13391 LDBL_MAX, which didn't conform to the C standard using the old
13393 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13394 now that we can do floating-point tests at compile time.
13396 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13398 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13399 and LDBL_EPSILON, as the resulting expression isn't an
13400 integer constant expression and violates the C standard.
13401 Problem reported by Nelson H. F. Beebe. Also, check
13402 for "L" suffix, and check that long double doesn't have
13403 worse range or precision than double, that mixed-mode
13404 arithmetic doesn't generate a diagnostic, that double
13405 constants fit in long double.
13407 2004-06-03 Kevin Ryde <user42@zip.com.au>
13409 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13410 malloc(0) and realloc(NULL,size).
13412 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13415 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13417 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13418 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13421 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13423 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13424 can be rewritten using if-then-else. Suggested by Bruno Haible.
13426 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13428 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13429 Problem reported by Stepan Kasal.
13431 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13433 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13434 change). Patch reported by Ralf Wildenhues in
13435 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13437 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13438 function F exists if the compiler and linker let you compile an
13439 expression like (F != 0). Recent versions of GCC optimize away
13440 the reference to F in that case, since every function address must
13441 be nonzero, so the link succeeds even if F does not exist.
13442 Problem reported by Manu in
13443 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13445 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13446 "Unix". Many uses changed.
13447 (Limitations of Builtins): Explain better why the ! command isn't
13450 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13452 * lib/autom4te.in (Automake-preselections): Preselect
13453 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13455 2004-05-19 Kevin Ryde <user42@zip.com.au>
13457 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13458 referencing AC_FUNC_STRERROR_R.
13460 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13461 note pessimistic assumption when cross compiling.
13463 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13465 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13466 (until 2004) invoked subcommands with sh -e, contra POSIX.
13467 Reported by Kevin Ryde.
13469 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13471 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13472 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13473 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13474 `test -f " /usr/bin/grep"', which _always_ failed.
13475 (AC_PROG_SED): Ditto bogus PATH fix.
13476 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13477 requires that grep correctly supports _multiple_ `-e' options, rather
13478 than stating only that grep should accept `-e'.
13480 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13482 Port to C99, which requires that 'exit' be declared.
13484 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13485 to ensure that stdlib.h is included.
13486 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13487 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13488 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13489 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13490 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13491 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13492 when using 'exit' in a test; C99 requires that 'exit' be declared.
13494 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13496 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13497 now prefers 'grep' implementations that accept -e.
13498 (Limitations of Usual Tools): Describe problems of traditional
13499 egrep and fgrep with long input lines, and of traditional grep
13501 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13502 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13503 All callers changed. Append /usr/xpg4/bin to the PATH, for
13505 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13506 the user with complaints about multiple -e options.
13507 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13508 Define it with AC_PROG_GREP.
13509 * configure.ac (AC_PROG_GREP): Add.
13510 * lib/freeze.mk (GREP): New macro.
13512 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13514 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13515 a possible candidate only after all others fail, rather than
13516 consulting it first. This improves backward compatibility by
13517 better reflecting the way shell selection occurred in previous
13518 versions of Autoconf, and should help to avoid triggering latent
13519 problems in other packages, such as the one in Automake where zsh
13520 is not handled robustly:
13521 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13522 Although it is not Autoconf's responsibility to work around
13523 problems in Automake, it nevertheless makes sense to avoid
13524 introducing unnecessary incompatibilites.
13526 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13527 Gary V. Vaughan <gary@gnu.org>
13529 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13530 how deeply nested we are when a suitable tool is found, set the
13531 ac_path_TOOL_found flag.
13532 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13533 nested we are in this macro. Break out of all 3 nested loops if
13534 ac_path_TOOL_found is set.
13536 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13538 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13539 of the _AS_PATH_WALK loop too if GNU flavor is found.
13541 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13543 * doc/autoconf.texi (Limitations of Make): Update documentation
13544 for `$<'. New entry `Long lines', based on a report from Simon
13545 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13546 paragraph about DJGPP, based on a mail from Richard Dawe.
13548 2004-04-20 Paul Eggert <eggert@twinsun.com>
13550 * tests/c.at (C keywords): Don't assume that GCC supports
13551 "restrict" and "inline", as sufficiently-old GCC versions do not
13552 (also, GCC configured to be in pedantic C89 mode does not).
13553 Problem reported by Sumit Pandya in:
13554 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13556 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13557 consider -g to work if it generates warnings when plain compiles
13558 don't. Problem reported by Braden McDaniel in:
13559 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13561 * doc/autoconf.texi (Slashes): New section, to document a problem
13562 reported by Jim Meyering in:
13563 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13565 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13566 linker output files before linking, to work around IRIX 6 linker bug.
13567 Problem reported by Rainer Orth in:
13568 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13570 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13572 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13573 best tool so far counter rely on the tool path variable name to
13574 avoid checks for one tool being affected by the results of running
13575 the length check on a previous tool.
13577 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13578 match expression argument, as different greps have different
13579 regular expression flavours.
13580 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13582 (AC_PROG_EGREP): Pass 'EGREP$'.
13583 (AC_PROG_GREP): Pass 'GREP$'.
13585 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13587 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13588 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13590 2004-03-29 Paul Eggert <eggert@twinsun.com>
13592 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13593 Types, Specific Compiler Characteristics, System Services,
13594 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13595 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13596 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
13597 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
13599 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

13608 2004-03-28 Paul Eggert <eggert@twinsun.com>
13610 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13611 now defines HAVE_DECL_TZNAME if it is declared, when
13612 HAVE_STRUCT_TM_TM_ZONE is not defined.
13613 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13614 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
13617 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
13619 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13620 superfluous backslashing of quotes (") in sed expressions;
13621 thanks to Paul Eggert.
13623 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
13625 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
13626 Fortran compiler is ifort, also added pghpf; thanks to Nelson
13627 H. F. Beebe for the bug report.
13629 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
13631 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
13632 quoted -cmdline argument in Portland Group compiler (bug
13633 reported by Jeffrey J. Barteet).

13643 inherits from language Autoconf-without-aclocal-m4.
13644 (Customizing autom4te): Adjust example; the cache must now be
13645 disabled for language Autoconf-without-aclocal-m4.

13672 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
13673 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
13674 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
13676 (AC_CHECK_ALIGNOF): New macro.
13677 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

13681 2004-03-03 Paul Eggert <eggert@twinsun.com>
13683 * bin/Makefile.am (edit): Don't use $< in a context where
13684 POSIX doesn't require support for it. Use $@.in instead.
13685 Problem reported by Anthony N. Frasso in
13686 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

13706 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
13707 $(m4sh_m4f_dependencies); this removes a FIXME.
13708 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
13709 (MAINTAINERCLEANFILES): Split into pieces,
13710 one per related section. Add $(srcdir)/wrapper.in.
13712 2004-02-09 Paul Eggert <eggert@twinsun.com>

13715 AC_SUBST provides no portable way to escape literal newlines.
13717 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13718 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13719 Darwin uses -lcrt2.o and there's little point to cataloging all
13720 the system variants. Partial fix reported by Andreas Waechter in:
13721 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

13727 * doc/autoconf.texi (AU_DEFUN): Fix English,
13728 suggested by Paul Eggert.
13729 * lib/autoconf/autoupdate.m4: Correct reference to
13730 acobsolete.m4, suggested by Alexandre Duret-Lutz.
13732 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
13734 * bin/autoupdate.in: Define __file__ so that warnings

13759 (_AS_RUN): Move it here, support testing with eval.
13760 (AS_REQUIRE_SHELL_FN): Require shell functions when
13762 (_AS_LINENO_WORKS): Put around braces, we do not
13763 trigger the bash bug anymore.

13765 use AS_INIT_WITH_SHELL_FN.
13766 * bin/autoconf.in, tests/wrapper.in: Regenerated.

13798 the 2003-05-22 change, which removed the older years from the list.
13799 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13807 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

13810 egrep and fgrep respectively if $GREP -E/-F don't work.
13811 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13812 _AC_PROG_GREP, and AC_PROG_SED.
13813 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13814 longest input length accepted by a command.

13845 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13846 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13847 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13848 not <inttypes.h>. Problem reported by Tim Mooney in
13849 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13850 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13853 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13854 otherwise "make check" fails because it forbids cmp (I guess
13855 because cmp treats files as binary on DOS-like systems).
13857 * tests/mktests.sh: Update copyright date to 2004, since some tests
13858 have changed in 2004.
13860 2004-01-23 Gary V. Vaughan <gary@gnu.org>

13863 non-truncating sed or gsed program in PATH.
13864 * tests/acprograms.at: Add it.
13865 * doc/autoconf.texi (Particular Programs): Document it.
13868 2004-01-15 Paul Eggert <eggert@twinsun.com>
13870 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13871 -std1 disables some useful extensions on Tru64. Problem reported
13872 by N. Lichtmaier in

13875 2004-01-14 Paul Eggert <eggert@twinsun.com>
13877 * doc/autoconf.texi (Programming in M4sh): Document that
13878 AS_MKDIR_P succeeds if the destination is a symbolic link
13879 to an existing directory.
13880 (Limitations of Usual Tools): Note that mkdir -p might not
13881 succeed on symlinks to directories.
13883 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13885 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

13895 2004-01-10 Jim Meyering <jim@meyering.net>

13899 2004-01-09 Paul Eggert <eggert@twinsun.com>
13901 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13902 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13903 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13904 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13905 AC_COMPILE_IFELSE, since we now assume our caller invokes
13906 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13907 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13908 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13909 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13911 2004-01-07 Paul Eggert <eggert@twinsun.com>
13913 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13914 `"'...'"`, as it's confusing (and I suspect it may not work on
13915 some platforms). The code was incorrect anyway, as it assumed
13916 that \$ evaluated to itself in that context. Reported by
13917 Alexandre Duret-Lutz.
13919 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13921 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13922 and _LT_AC_TAGCONFIG.

13949 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13950 Use "rm -f" to remove conftest.sed, not plain "rm".
13951 Bug reported by David Relson in
13952 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13954 * Makefile.am (autom4te-update):
13955 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

13971 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13972 -c -o might not work. From a suggestion by Kevin Ryde.
13973 (C Compiler, Generating Sources, Limitations
13974 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13975 Don't put '-o' after non-options, as POSIX doesn't allow this.
13976 Mention that cc's name might be gcc or c89 or whatever.
13978 2004-01-04 Kevin Ryde <user42@zip.com.au>
13980 * doc/autoconf.texi: Add various further index entries.

13987 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13989 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13990 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13991 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13992 explanation clearer.
13994 2003-12-24 Andreas Schwab <schwab@suse.de>
13996 * doc/autoconf.texi (Default Includes): Fix misspelling of

14003 * tests/atlocal.in: Store the result here.
14004 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14008 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14009 * tests/tools.at (Syntax of the shell scripts): Simplify

14079 parameter of AU_DEFUN.

14083 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
14084 the expanded body, consistently with other macros such as AC_USG.
14086 2003-11-17 Paul Eggert <eggert@twinsun.com>
14088 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
14089 into the initial confdefs.h, to work around a bug in NextStep 3.3
14090 patch 3 reported by Eric Sunshine.
14092 2003-11-15 Kevin Ryde <user42@zip.com.au>
14094 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
14095 than $target since the latter is not usual, add guidelines on when to
14096 use or not use the system type.

14100 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

14273 Problems reported by Eric Sunshine.
14275 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
14277 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
14278 -mGLOB_options_string stuff for Intel ifc, which can cause

14302 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14303 cache variable instead of $G77 to decide whether to include -O2,
14304 since $G77 is specific to Fortran 77.

14308 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14309 free" flag. Re-order flags tested into rough order of popularity.
14311 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14313 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14314 arguments so that it can be used with syntax identical to
14315 AC_PROG_F77, and so that we can more easily decide to
14316 remove/deprecate the DIALECT optional argument in the future if it
14317 proves troublesome.
14318 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14319 non-freeform-supporting compilers. Document freeform flags.
14321 2003-10-03 Akim Demaille <akim@epita.fr>

14383 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14384 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14385 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

14388 2003-09-26 Akim Demaille <akim@epita.fr>
14390 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14391 directory for AC_CONFIG_COMMANDS' first argument exists.
14392 This makes valid the invocation of _AC_SRCPATH that follows.
14393 Reported by Eric Sunshine.

14417 The test suite are sometimes assigning timings incorrectly.
14418 Reported by Henk Krus.
14419 Diagnosed by Nicolas Joly.
14421 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14423 Instead of making AT_help a sequence of assignments to grow
14424 $at_help_all, just make AT_help_all be the growing contents of
14425 $at_help_all, and make a single assignment in...
14427 (at_times_skip): Flip the meaning and rename as...
14428 (at_times_p): this.

14439 (ifnames): chmod -w.
14440 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14441 executables, not bin/ executables! Otherwise all the magic needed
14442 to find non installed files is turned off. This caused a failure
14443 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14444 as found in its environment (sent by tests/autoreconf): pointing
14445 to bin/autom4te that could not find its files.
14446 * tests/mktests.sh: Force the replacement of generated files, for
14447 the sake of "mv" program that are interactive when overwriting a

14497 2003-09-10 Akim Demaille <akim@epita.fr>
14499 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
14500 and AC_FC_FREEFORM.

14542 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14544 Add support for newer Fortran dialects. The F77 interface is
14545 unchanged, and continues to support Fortran 77. New FC macros
14546 correspond to all the old F77 macros, with output variables FC,
14547 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14548 available dialect, but older dialects can be specified. There are
14549 new macros AC_FC_SRCEXT to set the source extension, and
14550 AC_FC_FREEFORM to accept free-form source files.
14552 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

14589 are defaulted by AT_CHECK anyway.
14590 Use AT_CHECK_AUTOM4TE.

14674 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14676 2003-08-21 Akim Demaille <akim@epita.fr>
14678 First stab at preserving warnings between calls to autom4te,
14679 including when the cache is used.
14681 There are still several issues: (i) there are too many runs of m4
14682 (one for include, one for warnings, and some more), (ii) warnings
14683 spreading on several lines are not handled gracefully, (iii) the
14684 code meant to have the call stack display for errors does not work
14685 (its handling should move from m4 to autom4te).
14687 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14689 (@preselect): Add m4_warn.
14690 ($exit_status): Remove, use $exit_code.
14691 ($help): Use Autom4te::ChannelDefs::usage.
14692 (&handle_m4): No longer define the m4_warnings.
14693 At each run, extract and report the warnings.
14694 Always cache the result, including if the exit status is on
14695 failure, since if nothing changes, we should result in the same
14696 failure, hence we can use the cache.
14697 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14698 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14700 (m4_warn): Redefine as a do-nothing: it is its invocation that
14701 matters, as warnings are now reported via traces.
14702 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14703 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14704 the latter reveals calls to the former.
14708 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14710 2003-08-21 Akim Demaille <akim@epita.fr>
14712 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

14721 (&usage): Return a string, not a side effect.
14722 (cross): New warning category.

14742 * bin/autom4te: Adjust.
14743 In particular, be Autoconf tools are really silent when properly
14744 working, bind the verbosity of the 'note' channel to $verbose.
14745 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14746 (&xsystem, &contents): Remove, since they are exported by...
14747 * lib/Autom4te/FileUtils.pm: this.
14749 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
14750 * lib/Autom4te/FileUtils.pm: here.
14752 2003-08-20 Akim Demaille <akim@epita.fr>
14754 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

14865 From Gareth McCaughan.
14867 2003-06-23 Akim Demaille <akim@epita.fr>
14869 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14870 not all of them. This fixes 1. the fact that when testing
14871 Autoconf there are many many config.log, 2. the incorrect use of
14872 top_srcdir to find config.log.
14873 Don't mix the detailed output of failed test with the summary of
14874 failures. Rather, append detailed log afterwards.
14876 2003-06-23 Akim Demaille <akim@epita.fr>
14878 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
14879 always run: output config.log on $at_group_log.

14958 altered by WEXITSTATUS.
14959 (xqx, xsystem): Use handle_exec_errors.
14961 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14963 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14964 Do not call `_exit()', simply modify `$?'.
14965 (xsystem): Reset $! before running system, and check it afterward.
14966 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14967 63 for version mismatches.
14969 2003-05-23 Akim Demaille <akim@epita.fr>
14971 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14972 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14973 the middle of a line).

14979 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14980 exit 63, so that we (or Automake's "missing") can tell the
14981 difference with a plain failure.

14991 Paul Eggert <eggert@twinsun.com>
14993 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14994 Remove `#include <stdlib.h>' from the list; we should never
14995 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14996 resulting namespace pollution would cause other tests to fail.
14997 Configure scripts run with some older versions of g++ and HP's
14998 aCC would fail due to such an #include. Problems reported by
14999 Matthew Mueller in <http://bugs.debian.org/120704> and by
15001 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15002 In the test, use the test declaration before including <stdlib.h>,
15003 as that's closer to how it'll be used.

15007 * doc/autoconf.texi (Header Portability): ucred.h.
15010 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15012 Overhaul Autotest's logging: generate separate log files
15013 in testsuite.dir/NNN/testsuite.log, and append them to
15014 testsuite.log instead of re-running the test verbosely.
15016 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15017 file descriptor, write 0 to at_status_file instead of setting
15018 at_status=0, initialize some new variables (at_status_file,
15019 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15020 to rerun the tests, instead append the at_group_log to the
15021 at_suite_log when a test fails.
15022 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15023 with the AS_MESSAGE_LOG_FD redirected to stdout.
15024 (AT_CLEANUP): save the output status in $at_status_file
15025 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15026 its original place.
15027 (AT_CHECK): since tests are run with a redirected stdout,
15028 and used to be re-run in verbose mode, turn some $at_verbose
15029 into echo, and don't redirect the output of testing stdout
15032 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15033 the name of the debugging directory and information about

15157 by aclocal.m4 is changed it might require the importing of another
15158 m4 extension file, i.e., aclocal must be run.
15160 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15161 (&parse_args): Use --force with aclocal if required and supported.
15162 (&autoreconf_current_directory): Use &run_aclocal.

15166 Lock autom4te's cache.
15168 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
15169 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
15170 argument instead of a file name, so that the request file remains
15171 open during the whole autom4te run.
15172 ($icache_file): New.
15173 (&freeze): Lock the $icache_file.
15175 2003-04-29 Derek Price <derek@ximbiot.com>
15177 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15178 seperator with m4_append_uniq(). It doesn't work.
15179 (AT_CLEANUP): Add `;' to end of at_help_all.
15180 (AT_INIT): Allow --keywords to be specified more than once. When
15181 grepping $at_help_all for keywords, use the field and keyword
15182 seperators to ensure a complete keyword match. Alter at_prev handling
15183 to support the new --keywords behavior.
15185 2003-04-27 Karl Berry <karl@freefriends.org>
15187 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15188 align better with others. I also made some of the individual
15189 entries on one line, for brevity and to make it easier for me to
15190 sort my dir-example file in the Texinfo distribution :).

15255 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
15256 reading the section "Present But Cannot Be Compiled" when the
15257 header causes problems.
15259 2003-03-28 Akim Demaille <akim@epita.fr>
15261 * tests/torture.at (Configuring subdirectories): Require aclocal
15262 1.4, otherwise the test fails, as it does support configure.ac.
15263 This fixes the "test 40 failed" bug reports.
15265 2003-03-28 Akim Demaille <akim@epita.fr>
15267 * doc/autoconf.texi (C Compiler): `#line' portability.

15283 2003-03-26 Derek Price <derek@ximbiot.com>
15285 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
15286 obsolete AC_HELP_STRING.
15287 (AC_HELP_STRING): AU_DEFUN to...
15288 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
15289 * tests/m4sh.at (AS_HELP_STRING): New test.
15291 * tests/acgeneral.at: Regenerated.
15293 2003-03-26 Derek Price <derek@ximbiot.com>
15295 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
15296 sense. Verbosify the diversion definitions comment.

15321 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): Normalize
15322 file name for the m4 program, when it has an "exe" file extension.
15323 DJGPP's error messages include the error code in brackets -
15324 remove the error code during normalization.

15333 about `$<' in inference rules, it was a bogus interpretation of
15334 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
15335 Tru64 make in the "target lookup" section.
15336 (Automake): Automake 1.5+ no longer requires special tools to be
15337 present on the developer's host.
15339 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
15341 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
15342 to a shell that can handle redirection or quoting correctly.
15343 Override SHELL with the shell detected by configure.
15344 Use of $^O suggested by Tim van Holder.
15345 * bin/autom4te.in (BEGIN): Likewise.
15346 * bin/autoreconf.in (BEGIN): Likewise.
15347 * bin/autoscan.in (BEGIN): Likewise.
15348 * bin/autoupdate.in (BEGIN): Likewise.
15349 * bin/ifnames.in (BEGIN): Likewise.
15351 * bin/ifnames.in: Add final newline to help and version messages.
15353 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15354 to cope with DOS-style absolute paths, when constructing
15357 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15358 When constructing paths with IFS=:, quote the path. If we're
15359 constructing a DOS-style absolute path, we don't want to split it
15362 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
15365 2003-02-25 Pavel Roskin <proski@gnu.org>
15367 * bin/autoheader.in: Add missing newline when printing

15372 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
15373 2002-09-01 patch by replacing "test -n" with "test -z".
15374 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
15375 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
15377 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
15378 to fix a mismatch between example and discussion.
15380 2003-02-24 Kevin Ryde <user42@zip.com.au>
15382 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
15383 format starting with "-".
15385 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15387 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15388 is not portable inside Makefile.
15390 2003-02-20 Akim Demaille <akim@epita.fr>
15392 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15393 compiler says yeah, but preproc says nope, compiler is right.
15394 Conversely, prompt the reader to send a bug report to the
15395 maintainers of the package, not of Autoconf.
15397 2003-02-20 Klee Dienes <kdienes@apple.com>
15399 * bin/autoreconf.in (autoreconf_current_directory): Properly
15400 handle an empty aclocal.m4.

15404 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
15405 $ac_prefix_program.
15408 2002-12-23 Paul Eggert <eggert@twinsun.com>
15410 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15411 innocuous variant befor including <limits.h> or <assert.h>. This
15412 works around a bug reported by Albert Chin: HP-UX 11i
15413 (and earlier versions) have a <limits.h> that declares
15414 gettimeofday and many other functions.
15416 2002-12-03 Paul Eggert <eggert@twinsun.com>
15420 * NEWS, configure.ac: Update version.
15422 * doc/fdl.texi: Upgrade to FDL version 1.2.
15424 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15425 nontrivially in main's body, so that f's external declaration is
15426 not optimized away in AIX. This should fix the bug reported by
15428 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15430 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15431 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15432 defined, to support freestanding compilers. This should fix the
15433 bug reported by Momchil Velkov in
15434 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15436 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15437 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
15438 obsolete AC_CHECK_TYPE. The missing empty arg was reported

15440 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
15442 * Makefile.maint (www-gnu): New macro.
15443 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
15444 the location has moved.

15448 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15449 \(.*\) match is too long and there is something more to be checked.
15450 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
15452 2002-11-15 Akim Demaille <akim@epita.fr>

15468 Update from masters.
15470 2002-11-14 Akim Demaille <akim@epita.fr>
15472 * Makefile.maint: Sync with Bison, i.e.:
15473 (po-check): Scan .l and .y files instead of the
15474 .c and the .h files that they generate. This fixes the bug
15475 reported by Tim Van Holder in:
15476 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15477 Look for N_ as well as for _. Try to avoid matching #define for
15481 2002-11-14 Akim Demaille <akim@epita.fr>
15483 * doc/autoconf.texi (C Compiler): Compiling several files at once.
15484 From Paul Eggert and Albert Chin-A-Young.
15486 2002-11-14 Akim Demaille <akim@epita.fr>
15488 * doc/autoconf.texi (C Compiler): Solitary backslashes.
15489 From Paul Eggert and Albert Chin-A-Young.
15491 2002-11-14 Kevin Ryde <user42@zip.com.au>
15493 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15494 than assigning in main, to avoid HP cc +O3 optimizing it away.
15496 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15498 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15499 option. Process --recheck after parsing all options. Pass -q
15500 option to configure on --recheck.
15501 (AC_OUTPUT): Pass -q from configure to config.status.
15502 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15503 arguments to record.
15504 * doc/autoconf.texi (config.status Invocation): Document
15505 config.status -q option.
15507 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15509 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15510 Makefile.in if Makefile.am exists.
15511 (output): Strip `.am' from Makefiles. Don't
15512 output AC_CONFIG_FILES if no Makefiles were found.
15514 2002-11-07 Akim Demaille <akim@epita.fr>
15516 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
15517 (local_updates): New.

15519 (local_updates): New.
15521 2002-11-06 Akim Demaille <akim@epita.fr>
15523 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
15524 declaration in extern "C" too.

15532 Reported by Ezra Peisach.
15534 2002-11-05 Akim Demaille <akim@epita.fr>
15536 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15538 We _have_ to stop using the old compatibility scheme that tried to
15539 avoid useless backslashes because Libtool 1.4.3 contains a
15540 AC_DEFINE([error_t], [int],
15541 [Define to a type to use for \`error_t' if it is not
15542 otherwise available.])
15543 We _have_ to quote the single quote and backslashes with \. The
15544 old compatibility scheme saw that ` was backslashed, and therefore
15545 did not quote the single quote. Hence before this patch, Autoconf
15546 was not compatible with Libtool.
15548 2002-11-04 Paul Eggert <eggert@twinsun.com>
15550 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15567 (&autoreconf): here.
15568 ($help, $make, &parse_args, &autoreconf_current_directory):
15570 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15572 2002-10-31 Bruno Haible <bruno@clisp.org>

15586 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
15588 2002-10-31 Akim Demaille <akim@epita.fr>
15590 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
15591 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15592 Make variable, not a shell variable.
15593 Suggested by Bruno Haible.
15595 2002-10-31 Akim Demaille <akim@epita.fr>
15597 * bin/autom4te.in (load_configuration): Reject #args out of any
15600 2002-10-31 Akim Demaille <akim@epita.fr>
15602 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
15603 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
15604 (_AC_RUN_IFELSE): Use it.
15605 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

15613 * doc/autoconf.texi (autom4te Invocation): Adjust.
15614 Suggested by Tim van Holder.
15616 2002-10-29 Paul Eggert <eggert@twinsun.com>
15618 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
15619 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
15620 Problem reported by Bruno Haible.
15622 2002-10-29 Akim Demaille <akim@epita.fr>
15624 * doc/autoconf.texi (Header Templates): Put also in words what the
15625 pictures says to assist free style readers.
15626 (Customizing autom4te): s/--cache=/--cache /.
15628 2002-10-29 Akim Demaille <akim@epita.fr>
15630 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
15632 sparc_address_test returns void.
15633 Use it with an argument, as prototyped.
15636 2002-10-29 Akim Demaille <akim@epita.fr>
15638 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

15937 Reported by Alexandre Duret-Lutz.
15939 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16000 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16001 aclocal invocation, as Gettext macros might not be visible to

16004 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16005 Reported by Paul D. Smith.
16007 2002-10-08 Paul Eggert <eggert@twinsun.com>

16037 * tests/torture.at (Configuring subdirectories): Be robust to

16142 * bin/autoscan.in: Improve the comments.
16143 (&parse_args): Drop obsolete undocumented options.
16144 (&output_kind): Output warnings.
16145 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

16151 Reported by Ralf Corsepius.
16152 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16154 2002-09-26 Akim Demaille <akim@epita.fr>
16156 Single suffix rules and seperated dependencies are not portable.
16158 * doc/autoconf.texi (Installation Directory Variables): Update.
16159 (Limitations of Make): Some about `Single Suffix Rules and
16160 Separated Dependencies'.
16161 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16162 (ifnames, autoscan, autom4te): Un-factor into several rules.
16164 2002-09-25 Paul Eggert <eggert@twinsun.com>
16166 * BUGS (Interoperability bugs): New section. Mention libtool
16167 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16169 2002-09-24 Paul Eggert <eggert@twinsun.com>
16171 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16172 make handles suffix-rules differently from GNU make.
16174 * bin/Makefile.am (SUFFIXES, .in): Remove.
16175 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16176 Move the body of the old .in rule here.
16178 2002-09-16 Akim Demaille <akim@epita.fr>
16180 i960 compilers create `b.out' files by default.
16181 Reported by Ralf Corsepius.
16183 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16184 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16186 2002-09-13 Paul Eggert <eggert@twinsun.com>
16188 * doc/autoconf.texi (Particular Headers): Remove obsolete
16189 reference to `struct timezone' in the description of

16197 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16198 * Makefile.am: Adjust.
16200 2002-09-13 Akim Demaille <akim@epita.fr>
16202 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16203 reading config.log when the compiler is rejected.
16204 Suggested by Guido Draheim.
16206 2002-09-13 Akim Demaille <akim@epita.fr>
16208 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16209 (chdir_init) might hang when stat'ing mounted directories.
16210 Reported by Vance Shipley.
16212 2002-09-12 Akim Demaille <akim@epita.fr>
16214 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16217 2002-09-12 Akim Demaille <akim@epita.fr>
16219 * doc/autoconf.texi (Defining Symbols): Present two different
16220 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16221 difference between 1 argument calls, and 2-3 argument calls.
16223 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16225 * doc/autoconf.texi: Review grammar and punctuation.
16227 2002-09-11 Paul Eggert <eggert@twinsun.com>
16229 * doc/autoconf.texi: Fix minor formatting, spelling, and
16231 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16232 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16235 2002-09-11 Akim Demaille <akim@epita.fr>
16237 * doc/autoconf.texi (Questions): Rename as...
16239 (Defining Directories): New.
16241 2002-09-09 Akim Demaille <akim@epita.fr>
16243 * doc/autoconf.texi (Making testsuite Scripts): Update.
16244 Suggested by Nishio Futoshi.
16246 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16248 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16249 plain `@' is wanted.
16251 2002-09-09 Akim Demaille <akim@epita.fr>
16253 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16254 `duplicates', since the algorithm was too naive and could keep
16255 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16256 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16257 Reported by Ralf Corsepius.
16258 * tests/torture.at (Configuring subdirectories): Exercise these
16261 2002-09-09 Akim Demaille <akim@epita.fr>
16263 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16264 looking for a replacement file.
16265 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16266 directory is relative.
16267 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16268 directory definition.
16269 Reported by Andreas Schwab and Jim Meyering.
16271 2002-09-06 Akim Demaille <akim@epita.fr>
16273 * doc/autoconf.texi (Setting Output Variables): Clarify what
16274 precious variables are.
16275 Suggested by Pontus Skoeld.
16277 2002-09-05 Akim Demaille <akim@epita.fr>
16279 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16280 (ifnames, autoscan, autom4te): Since we don't only depend on
16281 configure.ac variables (such as VERSION etc.), but also on prefix
16282 and so forth, depend on Makefile, not configure.ac.
16283 Reported by Alexandre Duret-Lutz.
16284 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16286 2002-09-05 Kevin Ryde <user42@zip.com.au>
16288 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16289 doesn't seem to be confined to ia64, just say "some versions".
16291 2002-09-04 Akim Demaille <akim@epita.fr>
16293 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16295 * Makefile.am (maintainer-clean-local): Remove.
16296 (MAINTAINERCLEANFILES): Remove COPYING.
16298 2002-09-03 Paul Eggert <eggert@twinsun.com>
16300 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16301 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16304 2002-09-03 Akim Demaille <akim@epita.fr>
16306 * configure.ac: Bump to 2.53d.
16307 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16308 as of today, on Automake's team suggestion.
16310 2002-09-03 Akim Demaille <akim@epita.fr>
16314 2002-09-02 Akim Demaille <akim@epita.fr>
16316 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16318 * configure.ac: Disable SITE_MACRO_DIR.
16320 2002-09-02 Jim Meyering <meyering@lucent.com>
16322 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16323 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16324 Also, tweak grammar: s/make sure to/be sure to/.
16326 2002-09-02 Paul Eggert <eggert@twinsun.com>
16328 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16329 directory names are generally preferable to physical names.
16331 2002-09-02 Akim Demaille <akim@epita.fr>
16333 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16334 Reported by Raja R. Harinath.
16335 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16336 * bin/autoupdate.in: Use error instead of die.
16338 2002-09-01 Paul Eggert <eggert@twinsun.com>
16340 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16341 ordinary shell concatenation rather than echo+tr+sed command that
16342 runs afoul of a long-line-related sed bug in Solaris 8.
16344 * bin/autoheader.in (parse_args): --warning -> --warnings.
16346 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16347 stdout, as traditional "ls" does.
16348 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16349 _AC_COMPILER_EXEEXT_O): Likewise.
16350 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16352 * bin/autoconf.as: Add --prepend-include option. This patch was
16353 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16354 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16356 * bin/autoconf.in, configure: Regenerate.
16358 * doc/autoconf.texi (Special Shell Variables): Mention
16359 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16362 MAILPATH and set PS1, PS2, PS4 to default values, to work
16363 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16364 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16365 the Autoconf documentation specifies; fall back to "unset" only if
16366 this fails. Use a shell for-loop for this rather than an m4 loop,
16367 to shorten the output script.
16369 2002-08-30 Paul Eggert <eggert@twinsun.com>
16371 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16372 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16373 for the CDPATH problem. Document PWD.
16374 (Limitations of Builtins): Document the problem that "cd $foo" and
16375 "ls $foo" may refer to different directories in shells conforming
16376 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16377 example, since the old example is now out of date.
16379 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16380 FOO" and "ls FOO" talk about different directories; this catches
16381 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16384 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16385 of rolling our own unset.
16386 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16387 in practice we needn't worry about CDPATH if unset doesn't work.
16389 * Makefile.in, aclocal.m4, bin/Makefile.in,
16390 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16391 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16392 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16393 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16394 tests/Makefile.in: Regenerate with Automake 1.6.3.
16396 * config/config.guess, config/config.sub, config/mkinstalldirs:
16399 * configure: Regenerate with self.
16401 2002-08-30 Kevin Ryde <user42@zip.com.au>

16411 2002-08-29 Akim Demaille <akim@epita.fr>
16413 * lib/Autom4te/General.pm (&xqx): New.
16414 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16415 hand, which is not portable.
16417 * bin/autom4te.in: Use them.
16418 Use &error instead of die.
16419 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16422 2002-08-17 Paul Eggert <eggert@twinsun.com>
16424 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16425 default list of compilers to try, since it was long ago superseded
16426 by the ksh fc builtin. Suggested by Steven G. Johnson.
16428 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16430 * doc/autoconf.texi (Invoking autom4te): End the option table,
16431 fixing a bug introduced by the previous patch.
16432 (Limitations of Make): Add a 'target lookup' subentry in the
16433 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16435 2002-07-29 Mark D. Roth <roth@feep.net>
16437 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16438 options and use $AUTOM4TE_PATH.
16439 * doc/autoconf.texi: Remove documentation of autom4te
16440 --include-envvar and --site-macro-subdir options and document
16441 use of $AUTOM4TE_PATH.
16442 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16443 arguments from each language section.
16445 2002-07-29 Paul Eggert <eggert@twinsun.com>
16447 * doc/install.texi: Include copyright symbol in copyright notice.
16449 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16451 (AM_MAKEINFOFLAGS): New macro.
16452 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16453 * Makefile.am (INSTALL): Use the new macros.
16454 Use -o rather than --output, since "missing" does not grok --output.
16456 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16458 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16459 comments do not always work. Never trust the exit status of
16462 2002-07-24 Kevin Ryde <user42@zip.com.au>
16464 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16465 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16467 2002-07-23 Paul Eggert <eggert@twinsun.com>
16469 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16470 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16471 apparently treats PATH="nonexistent" as if it contained ".".
16472 Bug reported by Stefan `Sec' Zehl.
16474 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16476 * doc/autoconf.texi (Limitations of Make): Mention the special
16477 handling of the obj/ directory by BSD make.

16523 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
16524 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
16525 latter was not run.
16527 2002-07-17 Akim Demaille <akim@epita.fr>
16529 * lib/Autom4te/General.pm (find_file): Browse the directories in
16530 the order they are given.

16663 2002-06-07 Akim Demaille <akim@epita.fr>
16665 * bin/autom4te.in (warn_forbidden): When rejecting a token,

16742 This improves on an earlier suggestion by H. Peter Anvin.
16744 2002-05-16 Paul Eggert <eggert@twinsun.com>
16746 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16747 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16748 Both macros now accept an optional source-dir arg.
16749 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16751 * NEWS: Document this.
16752 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16754 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16755 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16756 not for GNU extensions; this undoes part of the 2000-11-03 change,
16757 reverting to 2.13-compatible behavior.
16758 Add new optional argument DIR.
16759 (AC_FUNC_FNMATCH_GNU): New macro.

16765 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16766 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16767 and it causes a 'test' syntax error if it fails.
16768 Bug reported by Stephen Gildea.
16770 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16771 If prototypes are supported, use them to check this at compile-time,
16772 instead of trying to check it at run-time. If we must do a run-time
16773 check, assume that setvbuf is standard when cross-compiling, as
16774 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16775 Bug reported by Paul D. Smith.
16777 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16778 argument specifying location of getloadavg.c. This removes a
16779 FIXME. This idea was taken from Jim Meyering's implementation in
16781 * doc/autoconf.texi (Particular Functions): Document this.
16782 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16783 that's what the code does; this fixes a bug reported by

16788 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16789 autopoint instead of gettextize.
16790 ($uses_alocal): Rename as...
16791 ($uses_aclocal): this.
16792 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16793 Suggested by Bruno Haible.
16795 2002-05-03 Akim Demaille <akim@epita.fr>
16797 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16799 2002-04-29 Paul Eggert <eggert@twinsun.com>
16801 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16802 files to be 1 second older; just set them to be the same time.
16803 Also, sleep 1 second after the first aclocal, to work around
16804 problems with sub-second time stamps on the input files.
16806 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16808 * doc/autoconf.texi: Mention "set -e -x" lossage
16809 under node "Limitations of Builtins".

16815 From Christian Cornelssen.
16817 2002-04-29 Akim Demaille <akim@epita.fr>
16819 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16820 of lack of $LINENO support, then the test will compare the $LINENO
16821 in testsuite vs. the lineno in the test file. This is wrong, of
16823 Be sure to protect it.
16824 Reported by Patrick Welche.
16826 2002-04-25 Akim Demaille <akim@epita.fr>
16828 * doc/autoconf.texi (Obsolete Macros): Typo.
16829 Reported by Vladimir Volovich.
16831 2002-04-25 Akim Demaille <akim@epita.fr>
16833 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16834 than some of the input files, hence, on the second run of aclocal,
16835 if some of its input are younger, make them older.
16836 Suggested by Paul Eggert.
16838 2002-04-25 Akim Demaille <akim@epita.fr>
16840 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16849 (_AC_INIT_PREPARE): Use them to log them.
16850 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16851 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16852 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16853 _AC_SUBST_FILES and _AC_SUBST_VARS.
16854 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16856 2002-04-24 Akim Demaille <akim@epita.fr>
16858 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16859 autoheader, so that automake does not complain about a missing
16860 config.h.in that was to be created.
16862 2002-04-23 Akim Demaille <akim@epita.fr>

17114 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
17117 2002-03-19 Akim Demaille <akim@epita.fr>

17123 2002-03-19 Akim Demaille <akim@epita.fr>

17126 From Nishio Futoshi.
17128 2002-03-19 Akim Demaille <akim@epita.fr>
17130 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
17132 2002-03-18 Paul Eggert <eggert@twinsun.com>
17134 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17135 (Limitations of Usual Tools): Add mkdir section.
17137 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17138 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17139 back on AS_DIRNAME to compute prefixes otherwise; this is
17140 roughly what mkinstalldirs does. That way, we need not have
17141 our own filename disassembler. The old disassembler did not
17142 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17144 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17145 Create at_test_all by a series of assignments,
17146 not by a single assignment of a long string. The latter causes ksh
17147 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17148 presumably because of a buffer overrun.
17150 2002-03-14 Paul Eggert <eggert@twinsun.com>
17152 * lib/autotest/general.m4 (at_times_skip):
17153 Renamed from at_times. Now a boolean.
17154 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17155 says 'times: not found'.
17157 2002-03-14 Akim Demaille <akim@epita.fr>
17159 * bin/autoreconf.in (&study_gettextize): New.
17160 (&autoreconf): Handle newest gettextize.

17202 2002-03-08 Akim Demaille <akim@epita.fr>
17204 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17205 aliases the actual variables, and modifications of the former
17208 2002-03-08 Akim Demaille <akim@epita.fr>
17210 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17211 because of C-c: have m4 output in tmp files, then mv them.

17234 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17235 * lib/autoconf/general.m4 (AC_INIT): More informative error
17236 message for LIBOBJ.
17238 2002-03-04 Akim Demaille <akim@epita.fr>

17243 2002-03-04 Akim Demaille <akim@epita.fr>
17245 * doc/autoconf.texi (Transforming Names): Equality between target
17246 and host is irrelevant.
17247 (Specifying Names, Canonicalizing): Remove all references to the
17248 backward compatibility hooks. Rather, collect them all into...
17249 (Hosts and Cross-Compilation): this new section.
17250 * doc/install.texi (System Type): Ditto.
17251 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17252 that `--host' implies cross-compilation.
17254 2002-03-04 Akim Demaille <akim@epita.fr>
17256 * doc/autoconf.texi (Evaluation Macros): New.
17257 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17259 (_m4_foreach): Define the variant with immediate evaluation so
17260 that it contains exactly the items, not an expression which
17261 evaluation is the current item.
17262 (m4_re_string, m4_re_word): Don't over quote them.
17264 2002-03-04 Akim Demaille <akim@epita.fr>
17266 Instead of having stacking `shift's evaluated at the end, let
17267 `foreach' loops immediately evaluate them.
17269 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17270 $*. This is the n-th time I change my mind, but hopefully this is
17273 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17275 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17276 it was only a hack for m4_text_wrap.
17277 (m4_car2): Remove, replaced by...
17279 (_m4_foreach): Adjust.
17280 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17281 m4_bpatsubst for clarification.

17332 Fix Autoconf PR/207:
17333 AC_PREFIX_PROGRAM fails with dashed program names
17335 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

17372 2002-02-05 Akim Demaille <akim@epita.fr>
17374 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17396 * bin/autom4te.in (&parse_args): Implement `frozen files are
17397 optional are the sum of the previous files on the command line'.
17398 Also, pass `--reload-state=' on them, so...
17399 (handle_m4): don't.

17401 (M4sh): Rely on M4sugar.

17439 2002-01-28 Akim Demaille <akim@epita.fr>
17441 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17442 AUTOTEST_PATH *after* it was set.
17443 Don't put `.' in the PATH: the user should be precise and `./' if
17444 needed. In addition, given that the test suite does some `cd', if
17445 `.' is in the path, the `tested programs' sections will report
17446 programs found in the test suite's directory, while during the
17447 tests (performed in their own directory), these programs are no
17448 longer visible. In other words, the results is confusing and
17450 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17497 Autoconf::General::getopt with non valid options.

17501 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

17519 * tests/Makefile.am (package.m4): New.
17520 EXTRA_DIST it since its a source.
17522 2002-01-06 Akim Demaille <akim@epita.fr>

17525 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17526 and PACKAGE_BUGREPORT from here...
17527 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17529 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17530 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17531 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
17532 * tests/tools.at (autoheader): Adjust.

17556 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17557 trailing files, don't apply `-rf' to files which might not be
17558 created by configure (core, core.*, and *.core), but just `rm -f'.
17559 Suggested by Jonathan Kamens.
17561 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

17600 variables, they are really part of the tokens.
17601 Split the input line on spaces and then look for tokens.
17602 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17603 because of `lex$U.$(OBJEXT)'.

17629 2001-11-26 Akim Demaille <akim@epita.fr>
17631 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
17632 Before, having a line containing the opening of a multi line
17633 comment made the whole line be ignored.
17635 2001-11-26 Akim Demaille <akim@epita.fr>
17637 * doc/autoconf.texi (Using an Autotest Test Suite): New.
17638 (testsuite Scripts): Be one of its subsection.
17639 (Autotest Logs): New.
17641 2001-11-26 Akim Demaille <akim@epita.fr>
17643 Test groups are now run two directories deeper.
17645 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17646 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17648 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17649 top_srcdir, builddir and top_builddir.
17650 Use `at_*dir' relatively to the directory containing the
17651 suite, use `*dir' when relatively to the current group dir.
17653 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17655 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17656 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17657 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17660 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17662 * doc/autoconf.texi (Using System Type): Add an example of `case
17663 $host' usage so people quit using `case $target' everywhere.
17665 2001-11-22 Akim Demaille <akim@epita.fr>
17667 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17668 spotted by Jim Meyering.
17670 2001-11-16 Paul Eggert <eggert@twinsun.com>
17672 This patch implements a `long double' suggestion by Oliver Kiddle.
17674 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17675 static, to catch errors if the value isn't known at compile-time
17676 and the compiler supports dynamic arrays. Change its name from
17677 `_array_' to `test_array' to avoid potential name clashes.
17678 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17679 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17680 better than double. Catch a bug in GCC 2.95.2 x86.
17681 * doc/autoconf.texi (C Compiler): Document the above.
17684 2001-11-13 Akim Demaille <akim@epita.fr>
17686 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17688 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17690 2001-11-13 Akim Demaille <akim@epita.fr>
17692 * lib/autotest/general.m4 (AT_INIT): After having run the test
17693 group, go back to the initial directory, not to at_suite_dir.
17695 2001-11-13 Akim Demaille <akim@epita.fr>
17697 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17698 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17699 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17701 (AT_CHECK_CONFIGURE): Use absolute paths.
17702 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17703 The problem is still the old one: there is no means in M4 (that I
17704 know about) to create a defining macro, because there is no means
17705 to create `$1' etc., therefore, the defining macro ``swallows''
17706 all the arguments meant to the defined macro.
17708 2001-11-13 Akim Demaille <akim@epita.fr>
17710 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17711 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17713 * tests/aclocal.m4: Remove, as it is no longer used.
17715 2001-11-13 Akim Demaille <akim@epita.fr>
17717 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17718 variable names when referring to a single test group, or to
17719 `suite' when referring to the whole test suite.
17720 `at_last_test' is removed: m4 compute at_format itself.
17721 (at_stdout, at_stder1, at_stderr): New variables.
17722 (AT_CHECK): Use them.
17724 2001-11-13 Akim Demaille <akim@epita.fr>
17726 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17728 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17729 Do it as soon as a test fails, don't wait till the end of the test
17731 Don't remove $as_me.[0-9]*, since these files no longer exist.
17733 2001-11-13 Akim Demaille <akim@epita.fr>
17735 * tests/tools.at: Use absolute paths, since we are no longer run
17738 2001-11-13 Akim Demaille <akim@epita.fr>
17740 Now that tests are running in their own private dir, there is no
17741 need to list the files to remove at the end of tests groups.
17743 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17744 (AT_data_files, at_data_files): Remove.
17745 (AT_CLEANUP, AT_DATA): Simplify.
17747 Remove the group dir if !debug && !failed.
17748 * tests/atspecific.m4: Adjust.
17750 2001-11-13 Akim Demaille <akim@epita.fr>
17752 Start a new layout for Autotest: `testsuite' creates
17753 `testsuite.dir' in which the at-check-line etc. files are to be
17754 found, and `testsuite.dir/003' where the test group 3 is run.
17756 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17757 at_check_line_file, at_format, at_test_normalized, at_group_dir
17759 Create the directories.
17760 Use absolute paths for at- files.
17761 (AT_CHECK): Adjust.
17763 2001-11-11 Michael Matz <matz@kde.org>
17765 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17767 (m4_car): Properly quote arguments.
17769 2001-11-13 Akim Demaille <akim@epita.fr>
17771 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17772 with stricter rules on LIBOBJS.
17774 2001-11-12 Paul Eggert <eggert@twinsun.com>
17776 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17777 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17780 2001-11-12 Akim Demaille <akim@epita.fr>
17782 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17784 2001-11-12 Akim Demaille <akim@epita.fr>
17786 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17787 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17788 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17789 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17790 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17791 specify to what the macro should be defined (typically to 1).
17793 2001-11-12 Akim Demaille <akim@epita.fr>
17795 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17798 2001-11-12 Akim Demaille <akim@epita.fr>
17800 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17801 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17802 definition used by Automake where LEX is +/- "${missing} lex" and
17803 `missing' itself contains variables.
17805 2001-11-12 Akim Demaille <akim@epita.fr>
17807 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17808 Now that M4sh pushes BODY, the comments were output at the end of
17811 2001-11-08 Akim Demaille <akim@epita.fr>
17813 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17814 that we can trace macros from aclocal.m4.
17815 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17816 obsoleted, and redirect to the former anyway.
17817 Reported by Ralf Corsepius.
17819 2001-11-08 Akim Demaille <akim@epita.fr>
17821 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17822 processed only if present.
17823 * tests/torture.at (Configuring subdirectories): Use autoreconf
17824 instead of successive calls to autoconf.
17825 Add a nonexistent subdirectory to exercise the patch above.
17826 Reported by Ralf Corsepius.
17828 2001-11-08 Kevin Ryde <user42@zip.com.au>
17830 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17831 doesn't accept .S files.
17833 2001-11-07 Akim Demaille <akim@epita.fr>
17835 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
17836 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
17837 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
17838 * bin/autom4te.in (warn_forbidden): New.
17839 (handle_output): Use it.
17840 Read m4_pattern_forbid with messages.
17842 2001-11-05 Akim Demaille <akim@epita.fr>
17844 * bin/autom4te.in (--normalize): Remove.
17845 * lib/autom4te.in: Adjust.
17847 2001-11-05 Akim Demaille <akim@epita.fr>
17849 * tests/Makefile.am (testsuite): Rename this target as...
17850 ($(TESTSUITE)): this.
17853 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17855 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17856 the --prefix option, also remove it's argument.
17858 2001-11-05 Akim Demaille <akim@epita.fr>
17860 * doc/autoconf.texi (testsuite Invocation): Update.
17861 (Writing testsuite.at): Update.
17863 2001-11-03 Akim Demaille <akim@epita.fr>
17865 * doc/autoconf.texi: s/@code/@command/ where appropriate.
17867 2001-11-03 Akim Demaille <akim@epita.fr>
17869 * lib/Autom4te/General.pm: (&catfile, &canonfile)
17870 (&file_name_is_absolute): New, wrappers around routines from
17872 Use and export them.
17873 (&find_configure_ac): Optionally take a directory where to look at.
17874 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17876 Default @ARGV to `.', not find_configure_ac.
17877 (&autoreconf): Argument is a directory.
17878 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17879 * doc/autoconf.texi (autoreconf Invocation): Update.
17881 2001-11-03 Akim Demaille <akim@epita.fr>
17883 * lib/Autom4te/General.pm (@export_vars, @export_subs)
17884 (@export_forward_subs): New.
17885 Add basename, dirname, and fileparse.
17887 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
17888 Don't look for aclocal flags if we already know aclocal is not
17890 Move aclocal.m4t only if it exists.
17891 Reported by Ezra Peisach.
17893 2001-11-03 Akim Demaille <akim@epita.fr>
17895 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17896 passed on command line, defaulting to ./configure.ac if present.
17897 (&maybe_autoreconf, File::Find): Remove, unused.
17898 (&autoreconf): If autoconf is not used, don't try to trace.
17900 2001-11-02 Akim Demaille <akim@epita.fr>
17902 * configure.ac: Bump to 2.52g.
17904 2001-11-02 Akim Demaille <akim@epita.fr>
17908 2001-11-02 Akim Demaille <akim@epita.fr>
17910 * config/config.guess, config/config.sub, doc/standards.texi:
17911 * config/lispdir.m4: Update from masters.
17912 * configure.ac: Bump to 2.52f.
17914 2001-11-02 Akim Demaille <akim@epita.fr>
17916 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17917 Don't run aclocal when aclocal.m4 is not from aclocal.
17919 Don't run libtoolize and gettextize if --install is not given.
17921 2001-11-01 Paul Eggert <eggert@twinsun.com>
17923 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17924 be invoked before _AS_LINENO_PREPARE.
17925 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17926 than character ranges.
17928 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17929 invoking AS_BASENAME. Set the locale variables to 'C' if
17930 possible, as POSIX requires this to get the traditional
17932 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17934 2001-10-31 Paul Eggert <eggert@twinsun.com>
17936 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17937 with {}, as that triggers a bug in Bash 2.05.
17939 (_AS_LINENO_PREPARE): Use Sed rather than
17940 Awk. Fix the sed prepass to work even if there are multiple
17941 instances of $LINENO on the same line. Do not substitute for
17942 other variables like $LINENOT. Do not check file dates; such a
17943 check is unreliable on sufficiently fast machines, and removing
17944 the check makes the code simpler and more reliable. Check for
17945 output and chmod failures.
17947 * doc/autoconf.texi (Special Shell Variables): Document
17950 2001-10-31 Akim Demaille <akim@epita.fr>
17952 * tests/Makefile.am (atconfig): Remove this target, Automake
17955 2001-10-31 Akim Demaille <akim@epita.fr>
17957 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17958 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17959 provided, while it is optional.
17960 * configure.ac: Adjust.
17962 2001-10-26 Paul Eggert <eggert@twinsun.com>
17964 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17965 lib/Autom4te/Struct.pm:
17966 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17969 * doc/autoconf.texi (Special Shell Variables): Document some
17970 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17972 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17973 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17974 eval $LINENO is not portable in practice.
17976 2001-10-24 Akim Demaille <akim@epita.fr>
17978 * lib/Autom4te/General.pm (backname): New.
17980 2001-10-24 Akim Demaille <akim@epita.fr>
17982 * m4/: Remove, merged into...
17985 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
17987 * doc/autoconf.texi (Shellology): Mention the problems with bash
17988 2.05's use of ANSI quoting in its `set' builtin.
17990 2001-10-22 Paul Eggert <eggert@twinsun.com>
17992 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17993 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17994 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17995 POSIX decided to standardize on the int flavor of strerror_r.
17996 Always do char* test, as there's no reason not to.
17997 Assign to a char* var, to catch strerror_r that returns int*.
17999 * doc/autoconf.texi (Particular Functions):
18000 Document the above changes. Also, document the fact that
18001 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18003 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18005 2001-10-20 Akim Demaille <akim@epita.fr>
18007 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
18008 the executable was missing from the log.
18010 2001-10-20 Akim Demaille <akim@epita.fr>
18012 * lib/Autom4te/General.pm (&update_file): If destination is
18013 unchanged, remove the source.
18014 (&up_to_date_p): Don't be verbose, be debug.
18015 * bin/autoreconf.in: No longer support --m4dir.
18016 (&autoreconf): Display the full path of the configure.ac we are
18018 Trace it only once.
18019 Be sure to honor --force with gettextize.
18020 Always run aclocal.
18021 * doc/autoconf.texi: Adjust.
18023 2001-10-20 Akim Demaille <akim@epita.fr>
18025 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18027 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18028 `intl' is already present, as it refuses unless --force.
18029 (&parse_args): Use -I, --include instead of the old Autoconf
18031 ($localdir, $autoconf_dir): Remove.
18033 (&maybe_autoreconf): New, to preserve $_ for File::Find.
18035 2001-10-19 Jens Petersen <petersen@redhat.com>
18037 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
18038 * doc/autoconf.texi (Particular Programs): Likewise.
18040 2001-10-19 Akim Demaille <akim@epita.fr>
18042 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
18043 file in @configure_input@.
18044 Don't mention `automatically' in addition to `generated'.
18045 * tests/torture.at (#define header templates): Adjust.
18047 2001-10-19 Akim Demaille <akim@epita.fr>
18049 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
18050 comment, explain how to install automatic mode selection.
18053 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
18055 * bin/autoreconf.in (autoreconf): Display the path to the
18056 configure.ac being studied.
18058 2001-10-18 Paul Eggert <eggert@twinsun.com>
18060 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
18061 long, to work around a bug in the HP C compiler version HP92453-01
18064 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
18065 (AS_BASENAME_EXPR): New macro.
18066 (AS_BASENAME_SED): Do not assume GNU sed semantics.
18067 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
18068 and fall back on 'sed' only if the other two fail. This makes
18069 AS_BASENAME act more like AS_DIRNAME.
18070 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
18071 contains white space.
18072 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
18073 Use AS_DIRNAME, since I think it's now DOS-friendly.
18074 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
18075 Allow "dirname //FOO" to return either / or //, as POSIX allows
18078 2001-10-10 Akim Demaille <akim@epita.fr>
18080 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
18081 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
18084 2001-10-10 Akim Demaille <akim@epita.fr>
18086 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
18087 m4_define, since...
18088 (_AS_ECHO_N): AS_REQUIREs it.
18090 2001-10-10 Akim Demaille <akim@epita.fr>
18092 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
18093 (AC_INCLUDES_DEFAULT): Move to...
18094 * lib/autoconf/headers.m4: here.
18095 * lib/autoconf/types.m4: Comment changes.
18096 * doc/autoconf.texi: Specify where the default includes are used
18097 in the macro prototypes.

18108 --debug, not when --verbose.
18109 * lib/autom4te.in (Autoreconf-preselections): New.
18110 (Autoconf): Use it.
18112 2001-10-08 Akim Demaille <akim@epita.fr>
18114 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
18116 2001-10-08 Akim Demaille <akim@epita.fr>
18118 * doc/autoconf.texi (autoreconf Invocation): Adjust.

18525 * lib/autotest/general.m4: Englishoes.
18526 From Tim Van Holder and Alexey Mahotkin.
18528 2001-09-18 Paul Eggert <eggert@twinsun.com>
18530 * doc/autoconf.texi (Common Shell Constructs): New node,
18531 documenting AS_DIRNAME.
18532 (Limitations of Usual Tools): Refer to it when discussing dirname.
18533 Also, update discussion of POSIX standard to reflect latest draft.

18536 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18538 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18539 Do not pass a first argument with leading '-'
18540 to expr, by parenthesizing initial integers that might be negative.
18542 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18543 now merely checks whether it is an error to pass an argument
18546 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18547 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18548 whether it is a (compile-time) error to pass an argument to
18549 getpgrp. This simpler test supports the revised documentation,
18550 and is all that AC_FUNC_GETPGRP's users really need.

18566 Add test for AS_BASENAME.
18567 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18568 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18569 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18570 * tests/base.at: Fixed the expected responses. The old ones were
18572 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18573 the documentation claims it should (and how it behaved in 2.13).
18575 2001-09-18 Akim Demaille <akim@epita.fr>
18577 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

18582 No longer to be shipped.

18589 Expect `package.m4' to define the package signature.
18590 * lib/autom4te.in (Autotest): Add `package.m4?'.
18591 * tests/Makefile.am (package.m4): New.

18611 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):

18619 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18620 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18621 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18622 when they don't exist.
18624 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18625 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

18629 version with the version used by fileutils 4.1, except use

18675 * lib/autotest/general.m4 (AT_INIT): Create and remove
18676 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

18780 to avoid GCC warnings.
18783 2001-09-05 Akim Demaille <akim@epita.fr>

18787 2001-09-05 Akim Demaille <akim@epita.fr>
18789 Be ready to handle filenames as stupid as `dnl.at', for if even
18790 the maintainer is dumb enough to do that...
18792 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18793 excellence in M4 quotation: consider `__file__' is active.
18795 And BTW, when invoking m4, pass the --include in the right order:

18826 New, extracted from main.
18827 Use IO::File wherever possible.

18860 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
18861 (testsuite Scripts): There is no such thing as `atconfig.in'.

18866 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
18869 2001-08-31 Akim Demaille <akim@epita.fr>

18944 Map --localdir, --autoconf-dir onto it.
18945 Forward autom4te's options instead of interpreting them.

18947 There is no such envvar since the inception of autom4te.cfg.
18948 * bin/autom4te.in (&parse_args): Uniquify `@include'.

18969 * lib/Autom4te/General.pm (&find_peer): Remove.
18970 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
18971 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
18972 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18973 find the executables for it.
18974 * tests/Makefile.am: Major cleanup. Too lazy to document...
18975 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18977 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18978 indeed related to running the test suite, while passing
18979 --autoconf-dir and others is related to running non installed
18980 Autoconf executables. So don't do that, leave it to...

18982 * tests/autoscan: New.
18983 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

18999 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
19000 Suggested by Paul Eggert.
19002 2001-08-29 Akim Demaille <akim@epita.fr>
19004 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19005 download in a tmp dir.
19007 2001-08-29 Akim Demaille <akim@epita.fr>

19507 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
19508 endianness for comparison instead of relying on AT_CHECK_ENV.
19510 2001-08-11 Paul Eggert <eggert@twinsun.com>
19512 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

19546 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19548 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19549 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19550 * doc/autoconf.texi (C Compiler Characteristics): Update
19551 documentation for AC_C_BIGENDIAN.
19553 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19555 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
19556 magic values from an object file when cross-compiling.
19557 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19559 2001-08-10 Akim Demaille <akim@epita.fr>
19561 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19563 Suggested by Russ Allbery.
19565 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19567 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19568 current $prefix to the sub-configures.
19570 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19572 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19573 extension (needed on BeOS). Reported by Guido van Rossum.
19575 2001-08-09 Akim Demaille <akim@epita.fr>
19577 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19579 2001-08-07 Akim Demaille <akim@epita.fr>
19581 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19583 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19584 No need to remove the files before and after the each test, before
19585 each test and at the end of the suite is enough.
19586 Display only the children `times', not the shell's.
19587 If the test failed or was skipped, at-times is not available.
19589 2001-08-07 Akim Demaille <akim@epita.fr>
19591 Always produce testsuite.log, including when there are no
19592 failures. This helps getting information on skipped tests, and
19593 duration of the tests. Err, implement the latter btw.
19595 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19596 Dump information on the first run of each test.
19597 (AT_CLEANUP): Create `at-times' containing the duration of the
19600 2001-08-07 Akim Demaille <akim@epita.fr>
19602 The use of `dumpstat' revealed that `len' was used although it
19603 should not. m4_text_wrap was using it, but in the Autoconf world
19604 where it is legal. Hence (i) test M4sh in its own world, not
19605 Autoconf's, and (ii), ahem, fix the bug :)
19607 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19608 does not like `' instead of [].
19609 (AT_INIT): Forbid `^_?AT_'.
19610 And don't output such tokens.
19611 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19612 `script.as', and `autom4te.cache'.
19613 Remove `empty' and `macro' which are no longer used.
19614 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19615 * tests/m4sugar.at: Use it.
19616 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19618 2001-08-07 Akim Demaille <akim@epita.fr>
19620 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
19622 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
19624 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19626 2001-08-04 Akim Demaille <akim@epita.fr>
19628 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19629 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19631 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19632 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19633 (AC_F77_MAIN): Likewise.
19635 2001-08-04 Akim Demaille <akim@epita.fr>
19637 Don't rely on M4sugar outputting the patterns in files, since we
19638 might process the output _without_ running m4, hence without these
19641 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19642 * bin/autom4te.in (@Request::includes): Remove, unused.
19643 (@Request::source): Rename as...
19644 (@Request::input): this.
19645 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19646 (&handle_output): Fetch the patterns from the traces.
19647 `$forbidden' and `$allowed' are constant: use m//o.
19648 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
19649 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19651 2001-08-04 Akim Demaille <akim@epita.fr>
19653 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19654 autoconf', i.e., in addition to caching traces, cache the output.
19656 * bin/autom4te.in (Request::cache): Rename as...
19657 (Request::id): this.
19658 ($cache, $icache, $tcache, $ocache): New.
19659 (&handle_m4): Save M4 output in the cache instead of $tmp.
19660 (&handle_output): Adjust.
19661 (&up_to_date_p): Check that the output cache is up to date too.
19662 (top level): Run `&handle_m4' iff force or the cache is invalid.
19663 Run `&handle_output' if the output cache is more recent.
19665 2001-08-04 Akim Demaille <akim@epita.fr>
19667 * bin/autom4te.in ($force): New.
19668 (&parse_args, &print_usage): -f, --force is a new option.
19669 (&handle_output): CPP directives might have spaces after `#'.
19670 (&parse_args): The first file only can be frozen.
19672 2001-08-04 Akim Demaille <akim@epita.fr>
19674 Don't let autom4te compute the `include' traces several times:
19675 first check that the trace cache file is up to date, and then
19676 compare its timestamp with that of the output.
19678 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19679 the preamble. Don't require 5.005 as Autom4te::General does it,
19680 and better yet (use `use', not `require'!).
19681 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19682 Class::Struct as Autom4te::Struct.
19683 * lib/Autom4te/General.pm (File::stat): Use it.
19684 (&mtime): New, export it.
19685 * bin/autom4te.in: Use it.
19686 Declare `$req' is invalid if it is outdated.
19687 Don't declare it valid before saving it if something went wrong.
19689 2001-08-04 Akim Demaille <akim@epita.fr>
19691 Autom4te shall not encode Autoconf data, and preselecting traces
19692 must be proposed to the users.
19694 * bin/autom4te.in (@required_trace): Remove.
19696 (&parse_args, &print_usage): -p, --preselect is a new option.
19697 (&up_to_date_p): Adjust.
19698 * bin/autoconf.in: Preselect some Autoconf macros.
19700 2001-08-04 Akim Demaille <akim@epita.fr>
19702 * tests/tools.at (autoconf --trace: user macros): Check traces on
19703 macros invoked without arguments, and macros invoked with multiple
19706 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
19708 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
19711 2001-08-03 Akim Demaille <akim@epita.fr>
19713 * bin/autoconf.in ($@): Work around the usual sh bug.
19716 2001-08-03 Akim Demaille <akim@epita.fr>
19718 Clean up the handling of the M4 builtins tracing exception.
19720 * bin/autom4te.in (Request::request): Don't complete M4 builtins

19723 (@m4_builtin): this.
19724 (%m4_builtin_alternate_name): New.
19725 (&parse_args): Complete the trace requests with alternate names.

19732 m4_if, and m4_wrap.

19736 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
19737 (m4_divert_pop): Dump the whole diversion stack when a diversion
19739 * bin/autom4te.in (&handle_output): Remember of the first
19740 occurrence of a possibly undefined macro, not the last.
19741 Complain about the possibly undefined macros in the same order as
19742 the appear in the output.
19743 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19744 * tests/tools.at (autoconf: forbidden tokens, basic)
19745 (autoconf: forbidden tokens, exceptions): No longer sort
19746 autoconf's stderr, as it is now deterministic.
19747 Check that `dnl' is caught.
19749 2001-08-01 Akim Demaille <akim@epita.fr>
19751 * configure.ac: Bump to 2.52c.

19768 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
19769 `END', as `Autom4te::General::END' will be triggered.
19770 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19771 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
19772 system to run `mv', `rm', and `cmp'.

19776 * lib/Autom4te/General.pm (&unique): New.
