27 and http://austingroupbugs.net/view.php?id=255.
28 * doc/autoconf.texi (Shell Substitutions) <${var+value}>: New
30 <${var=literal}>: Tweak wording. Add mention of an ambiguity
32 * tests/torture.at (Substitute and define special characters):
33 Make test more robust; here, the outer "" is in a here-doc, and
34 does not violate the quoting rules of thumb just documented.
36 2010-08-25 Eric Blake <eblake@redhat.com>
38 m4sh: revert incorrect mix of "${a='b'}"
39 * bin/autoconf.as: Revert leak of literal '' into assignment.
40 * tests/tools.at (autom4te preselections): Likewise.
42 m4sh: revert regression in AS_TMPDIR

44 rename $tmp to $as_tmp was wrong; config.status relies on it.
46 m4sh: reduce size of AS_VAR_TEST_SET
47 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Make more compact.
49 tests: improve some shell assumption testing

85 2010-08-24 Paul Eggert <eggert@cs.ucla.edu>
87 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
88 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
89 &s;" test into the main program, as C99 might plausibly be
90 interpreted as not requiring support for this construction in
91 static initializers. Remove the "#if defined __xlc__" stuff, as
92 the bug is not present in recent xlc implementations, and they
93 reject the test for other (valid) reasons. People using ancient
94 xlc versions, if any, are suggested to update to fixed versions.

109 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by
110 extension clang) check in favor of a gnulib test. Force failure,
111 rather than merely testing for a compiler extension.

1727 Work around DJGPP shell function return bug with command substitutions.
1728 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1729 shell function which also contains a command substitution causes
1730 the shell to barf. For more details and a fix see:
1731 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>

1760 DJGPP fix: remove both conftest and conftest.exe.
1761 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1762 and both `conftest' and `conftest.exe' with `-o conftest', but not

3545 STOP (to avoid fork bombs with ksh).
3546 Inside the job processes, add PIPE handler to write back the

6627 Cover more potentially problemtic file names. Use the new
6630 Properly handle funny file names for headers in config.status.
6631 The test suite did not cover this bug because the code was not
6632 quoting properly the arguments of `rm -f' (which "fails" silently)
6633 as well as the arguments of `diff' (whose output was redirected to
6634 /dev/null so we couldn't see its error message).

6749 Add 'testsuite -C dir'.
6750 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6752 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6754 <DEFAULTS>: Delay computation of variables based on $at_dir...
6755 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6756 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6757 <PARSE_ARGS>: Parse new option.
6758 <HELP_TUNING>: Document it.
6759 * tests/autotest.at (Choosing where testsuite is run): New test

6768 build-aux/texinfo.tex: Sync from gnulib.

6774 * doc/autoconf.texi (Particular Programs): Do not mention the
6775 Autoconf version in which the AC_PROG_INSTALL change was done.
6776 Suggested by Paul Eggert.
6778 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6780 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6781 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6782 mode, we change to the source directory, also set $ac_pwd so we
6783 do not go back to the build tree for the next config subdir.
6784 * tests/torture.at (Deep Package): Extend test to contain two
6785 config subdirs on the top level.
6787 Fix parallel `maintainer-check'.
6788 * Makefile.am (maintainer-check-tests): Depend on `all'.
6789 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

6816 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6818 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6819 check_SCRIPTS. Building the wrappers for `all' allows help2man
6820 to use them for the manpages.
6821 Report by Benoit Sigoure.
6823 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6825 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6839 (m4_require): Use m4_do, not m4_join.
6841 Fix some whitespace tests on cygwin.
6842 * tests/tools.at (autom4te and whitespace in file names): Restore
6843 font-lock. Create $TMPDIR before it might be used.

6848 Optimize AC_REQUIRE.

6861 * tests/base.at (Input/Output): Likewise.
6862 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6863 config.guess, and config.sub to test source tree.

6865 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6866 * tests/torture.at (Substitute a 2000-byte string): Drop
6867 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6868 (Substitute a newline, datarootdir workaround): Likewise.
6869 (Define a newline): Adjust for linenumber changes in configure.ac.
6870 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

6879 * tests/m4sh.at (LINENO): Quote $0.
6881 Fix testsuite program wrapper for whitespace in `pwd`.
6882 The problem here is that the usual mantra is that command
6883 variables can contain arguments, thus we cannot just escape
6884 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6885 $top_builddir/tests directory early in $PATH, so that the
6886 wrappers are found by their plain name.
6887 * tests/wrapper.as: Put $testdir early in $PATH.
6888 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

6900 <at_func_create_debugging_script, Driver Loop>:
6901 Quote $at_group_dir.
6902 * tests/autotest.at (whitespace in absolute testdir): New test.
6904 * lib/autom4te.in: Quote @datadir@.
6906 Proper file name escaping in Autoconf programs and Perl modules.
6907 This includes escaping of characters special to the shell
6908 as well as special to Perl, e.g., leading `<' or `>'.
6909 For example, when $file starts with `>', `open ">$file"'
6910 wrongly tries to append to a different file.
6911 * bin/autoconf.as: Fix quoting for autom4te options.
6912 * lib/Autom4te/General.pm (shell_quote): New function, taken
6913 from coreutils, written by Jim Meyering.

6917 * bin/autoreconf.in (parse_args): Likewise.

6921 * bin/ifnames.in: Likewise, XFile usage fixes.
6922 * tests/tools.at (autom4te and whitespace in file names): Extend
6923 test. Test twice, with special characters allowed on w32, and the
6924 rest. Test leading and trailing whitespace, for `open_quote'.
6925 (autotools and whitespace in file names): New, analogous test.
6926 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6927 by Russ Allbery and Eric Blake.
6930 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6931 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6932 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6933 (update_file, contents): Use it.
6935 * Makefile.am (autom4te-update): Rewrite for git.
6937 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6939 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6941 Fix copyright years.
6942 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,

6955 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6957 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6958 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6959 #undef as this runs afoul of our new way of creating config.h.
6960 Problem reported by Jim Meyering in
6961 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

6965 Fix autom4te for unusual characters in input file names.
6966 * bin/autom4te.in (files_to_options): Quote active characters
6968 * tests/tools.at (autom4te and white space in file names):
6971 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6972 Document that Tru64 awk always splits $0.
6974 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6976 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6977 `#AT_STOP_...' line at the end of each test.
6979 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6981 * lib/autotest/general.m4 (AT_INIT): For awk line number
6982 extraction script, ensure `$at_group' has a defined value
6983 even for the empty set, and properly quote its usage inside
6986 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6988 * doc/autoconf.texi (Shell Functions): New chapter. Document
6989 IRIX sh $0 issue in functions, move content from ...
6990 (Portable Shell): ... here.
6991 (Shell Script Compiler): Note that shell functions are not
6992 totally unportable any more.
6994 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6995 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6997 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6998 extracting the line numbers of the last needed test.
7000 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7002 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7005 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7007 Fix IRIX testsuite debugging failures: $0 in functions.
7008 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7009 Do not use $0 inside a function, as IRIX sh will set that to the
7010 function name rather than the script invocation name.
7012 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7013 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7015 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7016 to extract test scripts.
7017 (AT_INIT): Extract and cache test script line numbers.
7019 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7021 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7022 subsequent fixups; the awk -> here-document conversion trashes
7023 performance too much with AIX sh.
7025 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7027 * tests/local.at: Do not test m4, perl with AT_TESTED.
7029 Diagnose and guard against write errors dealing with config.status.
7030 The general idea is this: all write failures from `configure'
7031 writing `config.status' are indicated by $ac_write_error, which
7032 is only checked at the end. This is safe because config.status
7033 code is not executed before the file is complete. Other write
7034 failures, be they inside config.status, or in sub shell/awk
7035 scripts spawned from configure or config.status, typically need
7036 earlier checking, as their results are used right afterwards.
7037 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7038 before writing config.status, check afterwards.
7039 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7040 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7041 Set `ac_write_error' for write failures to config.status. Barf
7042 upon write failures to temporary files.
7043 Adjust note about closing and reopening the here-document.
7044 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7045 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7046 reopening the here-document.
7047 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7048 Ensure `ac_write_error' does not escape into config.status.
7049 Also, add a couple of code paths not yet exercised in the test
7050 suite: a config file with input from stdin, and a config header
7052 Suggestion for catching write errors by Bruno Haible.
7054 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7056 Avoid error with Tru64 awk and testsuite lines with many words.
7057 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7058 reads the testsuite, set the field separator to an unusual value,
7059 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7060 even splits the input if $i, i>0, was never accessed in the script.
7062 Revert 2007-10-17 change.
7063 * TODO: Multiline args in config files and headers mean something
7064 different and are not fixed, see
7065 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
7066 Report by Stepan Kasal.
7068 * doc/autoconf.texi (Generic Programs): Fix typo.
7070 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7072 AC_*_TOOL does not canonicalize the prefix
7073 * doc/autoconf.texi (Generic Programs): Do not say that
7074 the *_TOOL macros canonicalize, they simply use the `host_alias'.
7076 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7078 Diagnose write errors in config.status instantiations.
7079 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7080 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7082 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7083 Extend test to also check for some write error failures, using...
7084 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7085 Report by Bruno Haible.
7088 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
7090 (_AT_CHECK): Use less indentation, to save space.
7092 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7094 Add witness macro for @top_build_prefix@ substitution.
7095 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
7096 (_AC_OUTPUT_FILE): Mention it here.
7098 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7099 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7101 * lib/autotest/general.m4 (at_func_test): Remove.
7102 (AT_INIT): Pre-extract test groups into separate files.
7103 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7104 Remove at-test-source files together with the $at_group_dir.
7105 * tests/autotest.at (Long test source lines): New test.
7107 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7109 Shell functions and variables may share a namespace.
7110 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
7113 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
7115 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7118 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7120 * lib/autoconf/status.m4: Fix a couple of comment typos.
7122 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7124 2007-11-13 Jim Meyering <meyering@redhat.com>
7126 Clean up the rule to create "expr".
7127 * tests/Makefile.am (expr): Don't redirect directly to target.
7128 Redirect just once, not for each echo statement.
7129 Use $@, not literal "expr".
7131 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7133 Don't worry about preprocessor when testing long long.
7134 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7135 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7136 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7137 These no longer check for preprocessor flaws.
7138 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7139 Do not check for preprocessor flaws.
7141 2007-11-13 Jim Meyering <meyering@redhat.com>
7143 Adapt dependencies, now that a version change doesn't modify configure.ac
7144 * GNUmakefile: Remove "make clean" kludge.
7145 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7147 Don't redirect directly to target.
7148 Use $@, not literal "version.m4".
7150 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7152 * doc/autoconf.texi (Making testsuite Scripts): Document
7153 ":;{" shorthand as in previous patch.
7155 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7157 * doc/autoconf.texi (Limitations of Builtins): Document problem
7158 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7160 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7161 Use ":;{" shorthand.
7162 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7164 2007-11-12 Jim Meyering <meyering@redhat.com>
7166 Add more non-srcdir build support.
7167 * GNUmakefile (dummy): Split a long line.
7168 Add -v option to autoreconf invocation.
7170 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7171 * GNUmakefile (dummy): Remove INSTALL.
7173 Remove racy commands to build scripts in bin/ and tests/.
7174 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7175 are guaranteed to be built, remove the rules that tried to build
7176 them. Before, with a parallel build, these rules could lead to
7177 two processes writing tests/wrapper.in concurrently.
7179 Build in man/ only *after* building in bin/ and tests/.
7180 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7181 in both bin/ and tests/.
7183 Accommodate non-srcdir build-from-checkout.
7184 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7185 Use git's --git-dir=$srcdir/.git option.
7186 Add quotes, in case tarball_version_file contains shell meta-characters.
7187 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7188 * configure.ac: Pass "." to git-version-gen.
7190 Avoid spurious test failures due to version skew.
7191 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7193 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7195 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7196 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7197 Remove conftest.dSYM directory.
7198 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7199 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7200 Remove `conftest.*' recursively.
7201 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7202 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7204 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7206 Report and analysis by Jeff Squyres and Peter O'Gorman.
7208 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7210 Fix typos in variable names.
7211 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7213 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7215 Document that $((expression)) is not portable.
7216 * doc/autoconf.texi (Shell Substitutions): Here.
7218 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7220 Ignore configure --help* errors due to LINENO-impaired shells.
7221 * tests/torture.at (Configuring subdirectories, Deep Package):
7222 In the --help* tests in read-only trees, make `.' temporarily
7223 writable again for the `stderr' file, and ignore errors due to
7224 the attempt to write configure.lineno.
7225 Report by Patrick Welche.
7227 2007-11-10 Jim Meyering <meyering@redhat.com>
7229 Generate package.m4 in build-dir, not srcdir.
7230 * tests/Makefile.am (package.m4): Adjust target.
7231 Don't redirect directly to $@.
7232 (CLEANFILES): Add package.m4.
7233 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7235 When running $(AUTOTEST), search "." before searching $(srcdir).
7237 Avoid a race condition that would make parallel "distclean" fail.
7238 * tests/Makefile.am (distclean-generic): Replace the default,
7239 automake-provided rule with an identical one, but with an additional
7240 dependency on distclean-local. Simply adding the dependency would
7241 cause automake not to emit the rule at all.
7242 * BUGS: Building with -jN works, now.
7244 Distribute git-version-gen.
7245 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7246 since GNUmakefile is distributed, and requires it for dist* rules.
7248 Remove two more generated files from version control.
7249 * INSTALL: Remove generated file.
7250 * lib/autoscan/autoscan.list: Remove generated file.
7252 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7254 * GNUmakefile (PATH): Remove stray apostrophes; they become
7255 part of PATH, which isn't wanted here.
7257 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7259 New config files output variable `top_build_prefix'.
7260 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7262 * doc/autoconf.texi (Preset Output Variables): Document it.
7264 Report by Bob Friesenhahn.
7266 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7267 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7268 function, to parametrize arithmetic with expr vs. the shell.
7269 Use it where possible.
7270 Suggestion by Benoit Sigoure.
7272 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7274 Adjust the documentation of autotest WRT atlocal.
7275 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7276 when using Automake, to write a rule to produce atlocal, since it's
7277 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7278 distributed, not atconfig.in.
7280 2007-11-04 Eric Blake <ebb9@byu.net>
7282 Update list information.
7283 * README: Mention new autoconf-commit list.
7284 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7286 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7288 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7290 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7292 * build-aux/.gitignore: Ignore mkinstalldirs.
7294 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7296 2007-11-03 Jim Meyering <meyering@redhat.com>
7298 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7299 * build-aux/git-version-gen: This syncs from coreutils.
7301 Adjust the build procedure so "make check" works reliably.
7302 * README-hacking: Include an extra step between "make" and
7303 "make check" to ensure that the latter passes.
7305 Use just-built tools, when possible.
7306 * GNUmakefile (PATH): Set and export here, ...
7307 (dummy): ... rather than here.
7309 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7310 and Andreas Schwab <schwab@suse.de>

7315 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7317 * configure.ac (AC_PREREQ): Require version 2.60, for
7318 AC_PROG_SED, AC_PROG_GREP.
7320 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7321 and Jim Meyering <meyering@redhat.com>

7330 2007-11-03 Eric Blake <ebb9@byu.net>
7332 Support m4 1.4.5 in testsuite.
7333 * tests/torture.at (Define a newline): Exclude line numbers in
7335 Reported by Ralf Wildenhues.
7337 2007-11-03 Jim Meyering <meyering@redhat.com>
7339 Remove automake-provided files from version control.
7340 * build-aux/elisp-comp: Remove file.
7341 * build-aux/install-sh: Remove file.
7342 * build-aux/missing: Remove file.
7343 * build-aux/mdate-sh: Remove file.
7344 * build-aux/.gitignore: New file.
7345 Suggestion from Ralf Wildenhues.
7347 2007-11-03 Eric Blake <ebb9@byu.net>
7349 Adjust version comparison to account for git snapshot numbers.
7350 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

7353 <m4_version_compare>: Document this change.
7354 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7356 2007-10-30 Bruno Haible <bruno@clisp.org>
7358 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7359 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7360 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7361 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7362 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7363 Suggested by Paul Eggert.
7365 2007-10-28 Jim Meyering <meyering@redhat.com>
7367 * README-hacking: Autoconf, Automake, and Perl are required to build.
7368 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7370 2007-10-28 Jim Meyering <meyering@redhat.com>
7372 README-hacking: Recommend running autoreconf -vi.
7373 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7374 so that we use just-built tools when they're available.
7375 Suggestions from Ralf Wildenhues.
7377 2007-10-28 Jim Meyering <meyering@redhat.com>
7379 Make inter-release --version output more useful.
7381 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7382 which indicates that it is built using the 19th change set
7383 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7384 is a prefix of the commit SHA1.
7385 * build-aux/git-version-gen: New file.
7386 * configure.ac: Run it to set the version.
7387 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7388 * Makefile.am (dist-hook): Arrange so that .version appears only
7389 in distribution tarballs, never in a checked-out repository.
7390 * .gitignore: Add .version here, too. Just in case.
7391 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7392 not configure.ac, now that the version number changes automatically.
7394 Ensure that $(VERSION) is up to date for dist-related targets.
7395 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7396 git-version-gen doesn't match $(VERSION), but only for dist targets.
7398 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7435 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7438 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7440 Don't check for bug in HP-UX 11.00 cpp.
7441 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):

8670 must not be anonymous.

8672 for C++; this drops support for anonymous struct and union types,
8673 which were problematic anyway.

8693 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8694 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8695 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8696 works but the latter doesn't, then it's a valid type.
8697 This lets people use function types and so forth.
8698 For C++ there doesn't seem to be a simple solution, so leave it alone.
8699 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8700 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8701 AC_CHECK_TYPE; that wasn't documented or necessary.

8942 feedback. The most important changes document what happens when
8943 you convert an out-of-range value to a signed integer type, and
8944 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8947 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8948 rewrite, taking notions from the recent discussion on the gcc and
8949 autoconf mailing lists; please see
8950 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8951 and follow the many links.
8952 (Integer Overflow Basics, Signed Overflow Examples):
8953 (Optimization and Wraparound, Signed Overflow Advice):
8954 (Signed Integer Division): New sections.
8956 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8958 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8959 preprocessor macro arguments in traced name.
8960 * doc/autoconf.texi (Defining symbols): Document longstanding
8961 support for AC_DEFINE-ing macros with arguments, and document
8962 behavior when the same variable has multiple AC_DEFINEs.
8963 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8964 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8965 macros directly, giving much shorter and simpler code.
8967 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8969 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8970 space before "$ac_configure_args" to prevent a 'config.status
8971 --recheck' failure if ac_configure_args doesn't contain a leading
8972 space. This works around a problem with the XEmacs configure.ac,
8973 which uses the (undocumented) ac_configure_args variable
8974 inconsistently with Autoconf.
8976 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8978 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8979 Include <limits.h>, and use its INT_MAX to rewrite the
8980 j loop so that it does not overflow 'int'. Problem reported by
8982 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8983 Play it safe by shifting left by 1 rather than multiplying by 2,
8984 as GCC is less likely to optimize this away when the value
8985 is signed (when it assumes overflow leads to undefined behavior).
8986 Also, don't assume time_t uses two's complement.
8988 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8990 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8991 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8992 dumps core on it. Report by Tim Rice.
8994 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8996 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8997 --disable-option-checking to --help output even when
8998 AC_PRESERVE_HELP_ORDER is not used.
8999 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
9000 --with argument, rather than argument with [-.] replaced by
9002 * NEWS: Fix typo in previous change; the news was in the
9005 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
9007 * NEWS: Warnings are now generated by default for unknown
9008 --enable-* and --with-* options.
9009 * doc/autoconf.texi (Option Checking): Renamed from
9010 (Configure Option Checking). Tighten up the wording a bit.
9011 (External Software, Package Options): Cross-reference to Option
9012 Checking, and use this to shorten our section.
9013 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9014 "$x" to test "x$foo" != x.
9015 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9016 Don't warn if $enable_option_checking is "no".
9017 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9018 ac_unrecognized_opts to the empty string.
9019 Don't echo the unrecognized opts, as this might mishandle
9020 backslashes or leading -.
9021 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9022 usage next to the other --disable-FEATURE options in the
9025 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9027 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9028 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9029 Print warning for unrecognized --with and --enable options
9030 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9031 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9032 Disable option checking when subdirs are configured.
9033 (AC_OUTPUT): If warnings are enabled, print warning about
9034 unrecognized --with and --enable options at the end of
9035 the configure output (as well as at the beginning).
9036 * doc/autoconf.texi (Option Checking): New node.
9037 Document new option warning functionality.
9039 2006-12-16 Eric Blake <ebb9@byu.net>
9041 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9042 * NEWS: Start news for current version.
9044 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9046 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9047 Define HAVE_GETMNTENT to 1, not to the empty string.
9048 Problem originally reported by Jochen Friedrich in
9049 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9051 This change prompted by a problem report by Andrey Simonenko in
9052 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9053 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9054 object-like macros only, in the traditional portable character
9056 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9057 Warn about attempts to define things that are not identifiers.
9058 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9059 awful hack that AC_DEFINEd macro names containing parentheses.
9061 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9063 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9064 too drastic, even if Texinfo in theory requires it for info mode.
9066 (config.status Invocation): Renamed back from Recreating a
9068 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9069 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9071 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9073 * NEWS: Version 2.61a.
9075 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9076 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9078 * NEWS: Document changes with echo and printf, and the lack
9079 of limits on the total size of multi-line values of substituted
9080 variables, and the AC_FUNC_FSEEKO fix.
9082 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9084 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9085 Writing configure.ac.
9086 (Autoconf Input Layout): Renamed from configure.ac Layout.
9087 (Recreating a Configuration): Renamed from config.status Invocation.
9088 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9089 (acconfig Header): Renamed from acconfig.h.
9090 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9091 (Writing Testsuites): Renamed from Writing testsuite.at.
9092 (Autom4te Cache): Renamed from autom4te.cache.
9094 * BUGS: Remove mention of VPATH problem, since it's now documented
9095 not to be a bug in the Autoconf build procedure itself, but rather
9096 a problem with the proprietary `make' programs.
9098 * doc/autoconf.texi (Build Directories): Add a cross reference
9101 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9102 * doc/standards.texi: Sync from gnulib.
9104 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9105 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9106 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9107 generated automatically.
9109 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9111 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9112 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9113 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9115 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9117 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9118 `CEOF$ac_eof' special marker, the awk script cannot contain a
9119 line matching `^CEOF', so this is not needed any more.
9120 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9121 special marker in the test.
9123 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9125 * tests/tools.at (autom4te preselections): Use `find -newer';
9126 remove one of the sleeps.
9128 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9129 more readable, using ...
9130 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9132 * doc/autoconf.texi (autoheader Invocation): Do not double-
9133 quote the parameter of `AH_BOTTOM' in the example.
9135 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9137 * doc/autoconf.texi (Configuration Headers): Remove the
9138 example with multiple input files.
9139 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9140 multiple input files.
9142 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9144 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9145 creating the awk substitution script, handle one input line at a
9146 time, so that the maximum length of a substituted (multi-line)
9147 value is not limited by the size of the sed pattern space.
9148 The trade-off is a slightly repetitive sed script.
9149 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9150 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9151 * tests/torture.at (Substitute a 2000-byte string): Increase the
9152 test with several long lines, they should not be caught by sed
9155 * tests/tools.at (autom4te preselections): New test, to flag
9156 entries missing from autom4te.cfg.
9157 Report by David Byron <dbyron@hheld.com>.
9159 * tests/torture.at (Substitute a 2000-byte string): Actually use
9160 AC_PROG_AWK, so the last change works as intended.
9161 (Substitute and define special characters): Likewise.
9162 (Substitute a newline): Likewise.
9164 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9165 instead of `awk' consistently.
9166 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9167 * tests/torture.at (Torturing config.status): Test both the
9168 result of AC_PROG_AWK and plain awk.
9169 (Substitute a 2000-byte string): Likewise.
9170 (Substitute and define special characters): Likewise.
9171 (Substitute a newline): Likewise.
9173 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9175 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9176 can be assigned to a function pointer. Problem reported by
9177 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9178 part of a patch by Ralf Wildenhues in that same bug report.
9180 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9182 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9183 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9185 2006-12-01 Eric Blake <ebb9@byu.net>
9187 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9188 cross-compiling from cygwin to mingw.
9189 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9190 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9191 to lib/autoconf/c.m4.
9193 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9195 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9196 string for more reliable failure. Wrap the entire test that
9197 causes the broken Solaris printf to dump core, in a subshell,
9198 so the segmentation fault message is reliably suppressed.
9199 Fix shell expansion errors by using /usr/ucb/echo always;
9200 avoid an error on systems without it by another subshell.
9201 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9202 subshell-$as_echo to `as_echo', for better error message.
9204 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9206 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9207 `BASH_SOURCE' contain a newline, set them to empty, as they may
9210 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9212 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9213 years and is too hard to maintain now. The last straw was
9214 reported by Jerker Baeck in
9215 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9216 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9217 * doc/autoconf.texi (Particular Functions): Move
9218 AC_FUNC_SETVBUF_REVERSED from here...
9219 (Obsolete Macros): ... to here. Say that it does nothing now.
9220 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9221 Turn into (almost) a no-op.
9223 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9225 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9226 These macros are obsolescent and new applications shouldn't need them.
9227 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9228 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
9229 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
9230 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
9231 (AC_FUNC_VPRINTF): Likewise.
9232 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
9233 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9234 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9236 * doc/autoconf.texi (Setting Output Variables): Mention that
9237 @VAR1@VAR2 has unspecified behavior. Problem reported by
9239 * NEWS: Mention this.
9241 * Makefile.am: Put only a single '#' into the copyright notice,
9242 so that it's also present in the output file. Standardize wording
9243 in makefile copyright notices to match GNU coding standards.
9244 * bin/Makefile.am: Likewise.

9252 * man/Makefile.am: Likewise.
9253 * tests/Makefile.am: Likewise.
9254 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
9257 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9260 in the sed script that mangles the awk script: delete up to the
9261 first exclamation mark only.
9262 * tests/torture.at (Substitute and define special characters):
9265 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9267 Rewrite config files generation: avoid quadratic growth in
9268 the number of substituted variables by using awk instead of sed
9269 for the bulk of the substitutions.
9270 * NEWS: Mention this.
9271 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9272 forbidden in the output (and thus input) file.
9273 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9274 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9275 generate just one large awk script for substitutions,
9276 eliminating much of the earlier complexity, while adding some
9277 new complexity. Only expand the substitution templates at
9278 configure time, for smaller configure script size. If
9279 _AC_SUBST_FILES are used, test 'awk' for working getline support
9280 at config.status time. If absent, interpolate through the
9281 shell. The awk script was written with much help
9282 from Paolo Bonzini and Paul Eggert.
9283 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9284 (_AC_SED_FRAG_NUM): Likewise.
9285 (_AC_SUBST_CMDS): Renamed from...
9286 (_AC_SED_CMDS): ...this.
9287 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9288 * tests/torture.at (Substitute a 2000-byte string): Also
9289 substitute a line with 1000 words, and a variable with several
9291 (Substitute and define special characters): Test awk special
9292 characters, and put substitution input strings `@foo@' in the
9293 output, to test that no recursion happens; test several other
9294 combinations from Paolo Bonzini.
9296 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9298 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9299 that replaced echo with AS_ECHO where this wasn't necessary.
9300 Problem reportd by Ralf Wildenhues.
9301 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9302 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9303 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9305 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9307 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9309 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9311 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9312 that traditional Awk lacks 3-arg "split". It has it.
9313 Mention that FS must be a single character, and a few other
9314 99-byte limits of traditional Awk.
9315 Mention that if (i in a) doesn't work with traditional Awk.
9317 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9319 * tests/autotest.at (BSx641-newline in command):
9320 (BS-BS-newline in command, BSx640-newline in command):
9321 (Newline-CODE-BS-newline in command):
9322 (Single-quote-BS-newline in command):
9323 (Single-quote-newline-BS-newline in command):
9324 Use printf '%s\n' instead of echo, for portability to hosts
9325 where echo interprets backslashes. This will break on hosts
9326 that lack printf, but for now let's assume all such hosts
9327 are dead (if not, we should get reports of test failures).
9329 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9331 'echo' has some portability problems, when given a first argument
9332 with a leading '-', or when given any argument containing '\'.
9333 Avoid using 'echo' in these cases.
9334 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9337 * lib/autotest/general.m4 (AT_INIT): Likewise.
9338 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
9339 argument might be unportable.

9358 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9359 * bin/autoconf.as: Redo verbose flag implementation, as the old
9360 scheme wouldn't work with AS_ECHO.
9361 * lib/autotest/general.m4 (AT_INIT): Likewise.
9362 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9363 Don't use ECHO_T, since ECHO_N is now reliable.
9364 * lib/autotest/general.m4 (AT_INIT): Likewise.
9365 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9366 rather than using a here-document to put the script into a file.
9367 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9369 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9370 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9371 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

9377 operand, as AS_ECHO requires. Avoid double file name expansion.
9378 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9379 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

9381 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

9396 * tests/autotest.at (Macro with backslash in a test title):
9397 Comment out for now, as this tests neither fails nor passes
9398 reliably. Problem reported by Ralf Wildenhues.

9485 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
9488 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9490 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9491 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9492 Imported from a similar patch to gnulib by Bruno Haible.
9494 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

9513 and Stepan Kasal <kasal@ucw.cz>
9515 Handle special characters in test case titles correctly.

9518 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9519 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9520 argument. Extend to check titles printed by ./micro-suite and

9523 Single-quote in a test title,
9524 Double-quote in a test title): Don't expect failure anymore.
9525 (Backslash in a test title): Put a non-whitespace character after the
9526 backslash so that Bourne shells might actually see it as an escape
9528 (Brackets in a test title,
9529 Pound in a test title,
9530 Comma in a test title,
9531 Quoted Macro in a test title,
9532 Macro in a test title,

9534 (Macro with backquote in a test title,
9535 Macro with double-quote in a test title,
9536 Macro with backslash in a test title): New tests expected to fail.
9537 * tests/torture.at (#define header templates): M4-quote this title in
9538 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9539 The visible effect was a stray [] in the testsuite output.
9541 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9543 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9544 `trap ... 0' inside a function, for AIX sh.
9546 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9548 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9549 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9550 5363) simply issues a warning when dividing by zero at compile
9551 time. Problem reported by Elias Pipping.
9553 2006-10-26 Eric Blake <ebb9@byu.net>
9556 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9557 show effect on macros that expand with commas.

9582 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9584 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9585 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9586 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9587 reported by Nelson H. F. Beebe for Coreutils 6.4.
9589 * tests/tools.at (autoconf --trace: user macros): Remove test
9590 for tracing multiline macros, since m4 1.4.7a uses a different
9591 way to number lines. Problem reported by Ralf Wildenhues.
9593 2006-10-24 Stepan Kasal <kasal@ucw.cz>

9617 * NEWS: Remove AC_CACHE_CHECK_INT.
9618 * doc/autoconf.texi (Caching Results): Likewise.
9619 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9620 AC_CACHE_CHECK_INT, since it's no longer public.
9621 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9622 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9652 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
9653 looking for special shell characters.
9654 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
9655 macro defined by AS_VAR_PUSHDEF before passing it as a

9667 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9669 (Imported from Automake.)
9670 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9671 which incorrectly sets the mode of an existing destination
9672 directory. In some cases the unpatched install-sh could do the
9673 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9674 system. We hope this is rare in practice, but it's clearly worth
9675 fixing. Problem reported by Alex Unleashed in
9676 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9677 Also, don't bother to check for -m bugs unless we're using -m;
9678 suggested by Stepan Kasal.

9682 Import this change from Automake:
9684 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
9685 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
9686 is enabled by default with gnu and gnits strictness.
9687 Report from Bruno Haible.
9689 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

9691 gnu and gnits modes.
9693 Import this change from Config:

9698 Import this change from Gnulib:
9700 2006-09-16 Karl Berry <karl@gnu.org>
9701 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
9702 to avoid sectioning errors.
9704 Import these changes from Texinfo:
9706 2006-10-04 Karl Berry <karl@gnu.org>
9707 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

9711 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
9712 (\code): must use new \...Char values, since now ` is active.
9714 2006-08-26 Karl Berry <karl@gnu.org>
9715 * build-aux/texinfo.tex (\textdegree): New command.
9717 2006-08-12 Karl Berry <karl@gnu.org>

9722 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
9724 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9726 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9727 added to the template can get mangled.
9729 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9731 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9732 include the default headers, and redefine obstack_chunk_alloc
9733 and obstack_chunk_free. Fixes false failure with glibc.
9735 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9737 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9750 the NonStop platform.
9751 * doc/autoconf.texi (Posix Variants): Likewise.
9752 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9754 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9755 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9756 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9757 Use a better substitute, by inspecting the output of "ls"
9758 rather than just using ":".
9759 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9760 rather than AS_EXECUTABLE_P, since we needn't worry about
9761 non-regular files here.
9763 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9764 due to configuration hassles with this. See Tonya Underwood's report
9765 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
9766 * doc/autoconf.texi (Special Shell Variables): Likewise.

9774 2006-10-11 Stepan Kasal <kasal@ucw.cz>
9776 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9777 initialization which is not inherited through the environment
9778 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9779 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
9781 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

9784 problems with mkdir -p -m.
9786 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9788 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9789 comment about ac_cpp_err; it was incorrect, and anyway
9790 ac_cpp_err is being removed below.
9791 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9792 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9793 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9795 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9796 with werror_flag and conftest.err and so forth. This is more
9797 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9798 and anyway the user shouldn't normally want to see this gorp logged.
9799 Problem reported by Ralf Wildenhues.
9800 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9801 empty, not 'no', since the rest of the code uses 'test -z'.
9803 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9805 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9806 Use a single call to AC_DO_TOKENS rather than multiple, for
9808 (_AC_LINK_IFELSE): Test that resulting file is executable.
9809 Problem reported by mwoehlke in
9810 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9812 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9813 than creating a file to use with test -x; this is much faster.
9815 2006-10-02 Bruno Haible <bruno@clisp.org>
9817 * lib/autom4te.in (Automake-preselections): Add
9818 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9820 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9822 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9823 standard error, `experr' should be used, not `expout'.
9825 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9827 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9828 fseeko testing program twice; just use the earlier result.
9829 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9830 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9831 still doesn't let the program compile.
9832 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9835 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9836 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9837 include it, without including anything else.
9838 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9840 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
9842 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9844 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9845 `error.h', and include it, for a `error_at_line' prototype.
9846 Use a nonempty format string in the link test.
9847 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9848 for a declaration of wait3.
9850 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9852 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
9853 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
9854 can apply to constants too, and that it checks for macro defns.
9855 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

10297 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
10299 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10301 * doc/autoconf.texi: Fix some typos.
10303 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10305 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10306 more globally, since the 2006-06-30 patch didn't suffice. Problem
10307 reported by Keith Marshall. Also, don't bother with builddir2,
10308 since it shouldn't be needed any more.
10310 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10312 * doc/autoconf.texi (Generic compiler characteristics):
10313 Document AC_COMPUTE_INT. Fix wrong statements on Default
10314 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
10316 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
10317 (_AC_COMPUTE_INT): Add obsoletion warnings.
10318 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
10321 * NEWS: Document change.
10323 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
10325 * doc/autoconf.texi (Volatile Objects): New section.
10327 * NEWS: Document previous change.
10329 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10331 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10332 Require that long long int be at least 64 bits wide. C99 requires
10333 this and enough programs depend on it so we should check for it.
10334 Bruno Haible reports in
10335 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10336 that long long int is 32 bits wide with some nonstandard compilers.
10337 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
10339 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10341 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10342 to a nonexistent file, so that we don't have to worry about
10343 a local site configuration that doesn't use /usr/local.
10344 Problem reported by Keith Marshall in
10345 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10347 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10349 * doc/autoconf.texi: Be more consistent about using @acronym with
10350 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10351 quite right (it talked about "OSF/Tru64", even though the
10352 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10353 and it even mentioned "OSF 4"!) and at this point there's little
10354 reason to talk about OSF any more, since it died in 1994.
10355 (Specific Compiler Characteristics): Simplify example of
10356 negative-size array.
10357 (File Descriptors): Reorder to make the text flow better.
10358 Remove joke about "appreciate the various levels"; I didn't get it.
10359 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10360 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10361 (File Descriptors, Limitations of Usual Tools):
10362 Tone down the advice against renaming or removing open files.
10363 (Limitations of Usual Tools): Add a new section, on 'rm'.
10365 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10367 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10368 -lXt in LIBS, idea from Karsten Hopp; this was due since
10371 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10372 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10373 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10374 (which belong to Xt, not X itself). See Debian bug 327655.
10376 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10378 * configure.ac (AC_INIT): Bump to 2.60a.
10381 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10385 * configure.ac, NEWS: Update.
10387 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10389 * config/texinfo.tex: Sync from upstream.
10391 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10392 quadrigraph correctly in traces.
10394 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10397 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10398 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10400 * doc/autoconf.texi (Changed Directory Variables): New node,
10401 to document the whole `datarootdir' business a bit better.
10403 * tests/torture.at (datarootdir workaround): Extend test.
10404 Prompted by report by Alexandre Julliard.
10406 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10408 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10409 when using default mode of IBM C 6 for AIX. Problem and two-line
10410 fix reported by Larry Jones.
10412 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10414 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10415 about literal '${datarootdir}' if a definition is found in the
10418 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10420 * NEWS: Use "M4" rather than "m4" when appropriate.
10421 Problem reported by Eric Blake.
10422 * doc/autoconf.texi: Likewise.
10423 Use @acronym around BSD, GCC, and GNU when appropriate.
10424 (Why GNU M4): Renamed from "Why GNU m4".
10425 (Redefined M4 Macros): Mention that Posix
10426 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10427 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10430 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10432 * bin/autom4te.in (handle_output): Do not forbid the empty
10434 * tests/tools.at (autoconf: the empty token): New test.
10436 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10438 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10439 calls, so that we do not care whether they are LIFO or FIFO;
10440 in the m4_wrap, do not check which diversion is the topmost
10441 one, just check that the stack is balanced at the end.
10442 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10443 base diversion forever--pop the previous diversion before
10444 opening the new one; consequently, remove the m4_wrap call.
10445 * lib/autotest/general.m4 (AT_INIT): Likewise.
10446 * tests/m4sugar.at: Do not use
10447 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10449 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10450 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10452 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10453 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10454 Rework example of m4wrap token-pasting trouble so that it doesn't
10455 care whether it's LIFO or FIFO.
10456 Fix some "contrary to"s that are awkward in English.
10458 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10460 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10461 to `yes' instead of `int$1_t' if the type is found, for more
10462 consistent configure output (where $1 is the number of bits).
10463 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10464 Suggested by Bruno Haible.
10466 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10467 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10468 with system headers. Report by Bruno Haible.
10470 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10472 * config/config.guess, config/config.sub: Sync from upstream.
10474 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10475 in order to avoid picking up an older installed frozen m4sh.m4f.
10476 Besides an outdated shell startup, this could have been created
10477 by an earlier M4 version with incompatible frozen file format.
10479 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10481 * README: Recommend m4 1.4.4 instead of 1.4.3..
10482 * doc/autoconf.texi: Likewise.
10483 (Special Chars in Names): Say that $(.FOO) is portable, as
10484 suggested by Stepan Kasal.
10485 (Installation Directory Variables, Build Directories):
10486 (Automatic Remaking, Subdirectories, Fortran Compiler):
10487 (Making testsuite Scripts, Defining Directories):
10488 Quote variable usages better.
10489 (Making testsuite Scripts): Add clean-local rule to makefile
10490 snippet, by Eric Blake.
10491 (Installation Directory Variables): Fix table item font.
10492 Reword slightly to clarify. Generalize advice about
10493 not using special characters to include all file-related
10494 vars, not just VPATH.
10495 (Special Chars in Variables): Warn about special characters in
10497 (Assignments): Clarify default-value example as suggested by
10499 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10500 (Special Shell Variables): Note leading ./ or ../, as suggested
10502 (Limitations of Builtins): Under cd, warn about CDPATH.
10503 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10506 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10508 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10509 `@var', for texi2html.
10510 (Systemology): Some more word wrapping, for DVI output.
10511 (autom4te Invocation): The short option for `--melt' is `-M',
10514 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10516 * doc/autoconf.texi: More formatting and English tweaks,
10517 many suggested by Ralf Wildenhues.
10518 Reword to avoid "@code{...}'s" and the like, since it's ugly
10519 with Emacs info mode. discontents -> woes.
10520 Put a few "will"s back. time stamp -> timestamp.
10521 side-effect -> side effect.
10523 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10525 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10526 Warn about $@ not persisting. Problem reported by Julien Danjou in
10527 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10528 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10529 Mention other special chars, too.
10531 2006-06-14 Eric Blake <ebb9@byu.net>
10533 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10535 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10537 * doc/autoconf.texi: Some systematic minor improvements, as
10538 follows. Use "makefile" when talking about makefiles
10539 generally (which might be named "makefile" or "Makefile" or even
10540 "foo.mk"), "Makefile" when talking about a specific makefile
10541 called "Makefile". This unclutters the text from weird quotes
10542 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10543 values" rather than "@var{foo}s" and similar constructs containing
10544 "}s". Use "Make rules" rather than "Makefile rules". Minor
10545 English-language improvements. Change the prefix "sub-" to "sub"
10547 Put blank lines around examples more consistently.
10548 Avoid "rather" and "very" as intensifiers.
10549 Avoid "will" as an auxiliary.
10550 (Limitations of Make): Split this node into....
10551 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10552 (Leading _ in Macro Names, Backslash-Newline-Newline):
10553 (Backslash-Newline Comments, Long Lines in Makefiles):
10554 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10555 (obj/ and Make, make -k Status, VPATH and Make):
10556 (VPATH and Double-colon, $< in Explicit Rules):
10557 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10558 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10559 New nodes, resulting from splitup of Limitations of Make.
10560 All cross-references changed. Raise the top node from
10561 a section to a chapter, and all subnodes accordingly.
10562 Redo the introductory wording to match the new organization.
10563 (Installation Directory Variables): Use an example that is
10564 closer to what Autoconf actually does. Mention that VPATH's
10565 value should not contain metacharacters or white space.
10566 (Fortran Compiler): Fix a VPATH bug in an example.
10567 (Leading _ in Macro Names): Mention that this problem is no longer
10568 of practical concern.
10569 (VPATH and Make): Reword the advice to make it clearer
10570 that Autoconf and Automake support VPATH in non-GNU make, but
10571 many packages have bugs in this area.
10572 ($< in Explicit Rules): Refer to Build Directories rather
10573 than using a (non-VPATH-safe) example.
10574 (Automatic Rule Rewriting): Mention the sort of disaster that
10575 can ensue with Solaris-style rule rewriting with VPATH.
10577 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10579 * doc/install.texi (Compilers and Options): Weaken the
10580 suggestion to use GNU make for VPATH builds.
10582 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10583 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10585 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10586 in regular expression.
10588 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10590 * doc/autoconf.texi (Installation Directory Variables):
10591 Drop extra @samp from `@table @samp' item.
10592 (Limitations of Usual Tools): Comment fix.
10593 Do not nest @samp just to point to other table items.
10594 (Writing testsuite.at) <AT_CHECK>: The second argument to
10595 `@dvar' is already @samp'ed.
10596 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10597 do not use @var in the second argument.
10599 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10601 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10602 $as_shell.exe too. Problem reported by Andreas Buening in
10603 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10605 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10607 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10608 `unused variable' compiler warning, for `-Wall -Werror'.
10609 Reported by Jaap Haitsma in
10610 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10612 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10614 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10615 case the compiler dumps core. Problem reported for
10616 OpenServer 5.0.7 by Tim Rice in
10617 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10618 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10621 2006-06-06 Tim Rice <tim@multitalents.net>.
10623 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10624 "ERROR" only shows up in "make check" output if there is an

10629 * tests/tools.at (automatically allowed tokens): Fix typo.
10631 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10633 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10635 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10636 typically overflows on x86 CPUs, even though the C standard
10637 requires otherwise.
10639 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10641 * configure.ac (AC_INIT): Bump to 2.59e.
10644 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10648 * config/texinfo.tex: Sync from upstream.
10650 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10651 seen, invoke libtoolize with `--ltdl' argument.
10652 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10654 Suggested by Eric Blake.
10656 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10658 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10659 reported by Ralf Wildenhues.

10675 * tests/base.at: Check AC_REQUIRE's error message.
10676 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10678 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10680 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10681 `expout' as the last parameter.
10682 * tests/tools.at: Adapt to the above change.
10684 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10686 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10687 information about race-free implementations of mkdir.
10689 2006-06-04 Eric Blake <ebb9@byu.net>
10691 * bin/autoreconf.in (help): Document M4 environment variable.

10694 * doc/autoconf.texi (autom4te Invocation): Likewise.
10696 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10698 * NEWS: GNU make now recommended for VPATH builds.
10699 Mention that some macros are now documented to be obsolescent.
10700 * doc/autoconf.texi:
10701 Prefer "current" to "modern" to describe
10702 currently-used (albeit perhaps old-fashioned) hosts.
10703 Mention which ancient features no longer need to be worried about.
10704 setgid -> set-group-ID
10705 setuid -> set-user-ID (these are the Posix terms)
10706 Fix some misuses of "only".
10707 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10708 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10709 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

10716 Mention that these macros are obsolescent.
10717 (Installation Directory Variables): shall -> should
10718 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10719 Mention that it's now safe to use 3 and 4.
10720 (Limitations of Usual Tools): cp -r is now specified by Posix.
10721 Omit longwinded and obsolescent discussion of cp -f.
10722 Modernize discussion of expr, ls.
10723 (Limitations of Make): Modernize discussion of VPATH builds.
10724 Mention $? as a workaround in some cases.
10725 * doc/install.texi (Basic Installation):
10726 Mention "./configure; make; make install" first. Be more
10727 specific about why this file is generic. Remove unnecessary
10728 parens. Remove misleading "only". Remove obsolete advice
10729 about csh. Don't say "configure" takes awhile; say it
10730 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10731 and CC=c99 rather than CC=c89, as these are blessed by current
10732 Posix. Recommend GNU make if doing a VPATH build.
10734 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10736 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

10740 and Paul Eggert <eggert@cs.ucla.edu>
10742 * doc/autoconf.texi (Here-Documents): Add details about the
10743 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

10755 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10757 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10758 about quoting the case statement, just in case.
10759 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10760 was fixed in ksh93g; reported by Ralf Wildenhues.
10762 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10764 * doc/autoconf.texi (System Services): Do not document
10765 overriding EXEEXT via ac_cv_exeext=ext.
10766 (Particular Programs) <AC_PROG_MKDIR_P>:
10767 Document that ${MKDIR_P} understands --.
10768 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10771 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10773 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10774 argument with leading hyphen. Problem reported by Paul Eggert.
10776 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10778 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10779 about quoting ac_try: quote all of it, if any of it seems suspicious.
10780 This means we don't have to worry about ${ or sed any more.
10781 Also, double-quote the case statement, to work around misuses via
10782 underquoting as reported by Ralf Wildenhues in
10783 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10784 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10785 undocumented and dangerous macro.
10786 Problem reported by Ralf Wildenhues in
10787 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
10789 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10791 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10792 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10793 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10795 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10797 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10798 since evidently some packages rely on the old, broken behavior.
10799 Problem reported by Ralf Wildenhues in
10800 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10801 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10802 pre-2006-05-26 definitions, but leave in the comments that
10803 these macros are dangerous and should not be used.
10804 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10805 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10806 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10807 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10808 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10810 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10812 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10813 the use of 'tr', since this is our only use of 'tr'.
10815 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10816 and Paul Eggert <eggert@cs.ucla.edu>
10818 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10819 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10821 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10823 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10824 the output file in the `${datarootdir}' test.
10826 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10827 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10829 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10830 mention of `datarootdir' in the input file(s), but literal
10831 `${datarootdir}' in the output file, and we haven't warned yet,
10832 then warn as well: the user may have (erroneously) used
10833 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10834 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10835 * tests/torture.at (datarootdir workaround): Extend this test.
10838 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10839 and Paul Eggert <eggert@cs.ucla.edu>
10841 * doc/autoconf.texi (autoheader Invocation): The first argument to
10842 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10843 alternatives and clear up the language a bit.
10845 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10847 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10848 ac_config_guess, ac_config_sub, ac_configure.
10849 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10850 Fix typo that prevented an unnecessary space from being removed.
10851 Problems reported by Ralf Wildenhues in:
10852 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10854 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10856 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10857 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10858 Don't use the term "thread-safe" to talk about mkdir race
10859 conditions, since the problem is more a process than a thread
10860 issue. Problem reported by Stepan Kasal in:
10861 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10862 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10863 the test for 'install' more closely. Look at MKDIR_P first.
10864 Look in the PATH, and at /opt/sfw/bin.
10865 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10866 Don't bother to try mkdir -p, since we already check mkdir --version;
10867 just look at the version number. (There's no easy way to check
10868 for race-free implementations.)
10869 * tests/tools.at (autoconf: subdirectories): Adjust to above
10870 changes, since MKDIR_P now might end in "/mkdir -p".
10872 * doc/autoconf.texi (autoheader Invocation): Mention that the
10873 first arg of AC_DEFINE_UNQUOTED must be a literal.
10874 Problem reported by Ben Pfaff in
10875 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10877 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10878 * doc/autoconf.texi (Special Chars in Variables): New section.
10879 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10880 (Installation Directory Variables): Quote $(datadir) better.
10881 (Limitations of Builtins): Describe some of eval's trickiness.
10883 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10884 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10885 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10886 in front of every arg, not just trailing args. Quote apostrophes.
10887 (_AC_EVAL_ECHO): New macro.
10888 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10889 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10891 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10892 exposed by quoting of eval argument. Put the command on line line
10894 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10895 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10896 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10897 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10898 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10899 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10900 Use eval more safely.
10901 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10902 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10904 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10905 lines, exposed by quoting of eval argument.
10907 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10908 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10910 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10911 initialization of `ac_cv_exeext', do not override it if it was
10912 already set, unless it was set to `no', for compatibility with
10913 Autoconf-2.13, and comment this.
10914 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10915 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10916 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10917 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10918 Document that this test may be overridden by setting
10921 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10923 Revert these two patches:
10925 2006-04-06 Eric Blake <ebb9@byu.net>
10926 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10927 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10930 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10931 Clean up _AC_COMPILER_EXEEXT* macros.
10932 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10933 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10934 ac_file to the name of the default output file and call
10935 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10936 initial `rm' of the candidate files...
10937 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10938 the same list in subsequent `rm' calls, and for the temporary
10939 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10940 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10941 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10942 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10943 no longer needed) by libtool. Make it a cache check.
10944 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10945 copied here by mistake.
10946 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10947 _AC_COMPILER_EXEEXT.
10948 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10949 _AC_COMPILER_OBJEXT directly.
10950 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10952 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10954 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10955 Fix description of how the buggy `sed' works.
10957 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10959 Sync from Automake:
10961 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10962 ENOLCK. Only mention `make -j' when applicable. Only raise
10963 fatal errors when `make -j' is involved. Improve error message.
10965 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10967 * doc/autoconf.texi (Here-Documents): We now know more about
10968 the variable expansion in here documents bug.
10969 Thanks to Tim Rice and Stepan Kasal.
10971 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10972 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10974 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10976 * tests/autotest.at (Multiline command from M4 expansion):
10977 No failure to be expected if the shell quotes newlines in
10978 commands in the `set -x' output. Report by Tim Rice.
10981 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10983 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10984 expansion in the here-documents used by config.status, as that
10985 runs afoul of the Korn shell version M-12/28/93d bug described in
10986 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10987 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10988 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10990 2006-05-23 Jim Meyering <jim@meyering.net>
10992 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10993 Fix typo introduced with 2006-04-02 change. It reversed the sense
10996 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10998 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10999 ac_dB slightly, to save bytes in the script.
11000 Max out at 50 lines, rather than 96; this is more likely
11001 (though not guaranteed) to avoid obscure 'sed' failures.
11003 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11005 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11006 `tr -d -' as bad option argument. Work around this by deleting
11007 an unrelated character.
11008 Report by Tim Rice <tim@multitalents.net>.
11010 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11011 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11012 Stepan Kasal <kasal@ucw.cz>
11014 * doc/autoconf.texi (Particular Programs): Do not promise that
11015 we always prefer the GNU version of the program, and that we
11016 search according to PATH; both rules can have exceptions.
11017 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11018 AC_PROG_SED. Move descriptions of limitations
11019 to the Limitations of Usual Tools section.
11020 (Limitations of Usual Tools) <sed>: Mention script length
11021 limitations with Solaris /usr/ucb/sed.
11022 <grep>: Fix wording for empty alternative. Mention that -c and
11023 -l should not be combined, and that -E and -F should not be
11026 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11027 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11029 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11030 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11032 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11034 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11035 AC_DEFINE is now passed to m4_pattern_allow.
11036 * NEWS: Mention that; likewise for AC_SUBST.
11037 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11038 the parameter to m4_pattern_allow.
11039 * tests/tools.at: Add a check for that.
11041 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11043 * lib/autoconf/status.m4: Fix typos.
11045 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11047 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11048 only the files that this macro generates.
11050 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11052 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11053 the HP-UX sed limitation of 99 commands, labels do not count.
11054 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11056 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11058 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11060 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11061 Import the following fix from coreutils:
11063 2006-01-13 Jim Meyering <jim@meyering.net>
11065 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11066 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11067 not double-quote uses of that variable, to accommodate the rare
11068 case in which getmntent is available in none of the libraries
11069 checked. This happens at least on FreeBSD 5.0.
11071 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11073 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11074 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11075 some other programs unwisely rely on these undocumented vars.
11076 But put in warning comments about them.
11077 Problem reported by Ralf Wildenhues in
11078 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11079 * NEWS: Document that these variables are intended to go away.
11081 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11083 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11084 and set the language to C++ (analogous to the equivalent Fortran
11087 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11088 * doc/autoconf.texi (C++ Compiler): Document it.
11089 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11092 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11094 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11095 that caused config.status to generate 100-command sed scripts; the
11096 portable limit is 99.
11098 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11100 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11101 variable `ac_d' instead of `d' to avoid infringing namespace.
11102 Report by Ralf Menzel.
11104 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11106 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11107 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11108 * tests/tools.at (autoconf: subdirectories): New test, taken from
11109 the corresponding problem report by Ralf Wildenhues in:
11110 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11112 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11113 Quote some uses of shell variables if they might suffer unexpected
11114 globbing. This doesn't fix all instances of quoting problems that
11115 I found, just the easy ones that look safe.
11116 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11117 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11118 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11119 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11120 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

11127 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11129 * bin/autoreconf.in ($help): Reword according to the manual.
11130 Suggested by Olly Betts.
11132 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11133 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11135 * bin/autoreconf.in: Pass the directory argument to
11136 `require_configure_ac'. Fix comment.
11137 * tests/torture.at (Configuring subdirectories): Expose this.
11138 Reported by Olly Betts.
11140 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11142 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11143 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11144 Automake as follows:
11146 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11147 `$configure_in' instead of `configure.in', to preserve
11148 directory component.
11150 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11152 * config/config.guess, config/config.sub, config/texinfo.tex,
11153 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11155 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11157 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11158 test for C99 conformance; (bool) 0.5 is an integer constant
11159 expression, but (bool) -0.5 is not. Problem reported by Fedor
11160 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11162 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11164 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11165 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11166 Warn about obsolete install-sh files. Remove stray sentence
11167 fragment and fix cross reference.
11168 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11169 install -d; this undoes the 2006-05-10 change.
11170 (MKDIR_P): Mark with AN_MAKEVAR.
11171 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11172 that we don't require $INSTALL to be thread-safe. Move comments
11173 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11174 of AC_PROG_INSTALL. Output a message saying that we're checking
11175 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11176 MKDIR_P instead of AC_SUBST.
11177 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11178 Special magic for MKDIR_P, too.
11179 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11181 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11183 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11185 Sync from Automake, as follows:
11187 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11188 * config/install-sh: Initialize IFS, so field splitting isn't
11190 * config/mkinstalldirs: Likewise.
11191 * config/missing: Remove superfluous quotes. Replace all uses of
11192 `[' by `test', for consistency, and for..
11193 * config/missing (sed_minuso, sed_output): New variables.
11194 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11195 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11196 Fixes `missing' to detect `--output' for help2man. Fixes
11197 PR automake/483. Report by Dennis J. Linse.
11198 (autom4te): Document in `missing --help'.
11200 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11202 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11203 * config/install-sh: Don't use 'path' to talk about file names,
11204 as per GNU coding standards. Close a race condition reported by Ralf
11205 Wildenhues and Stepan Kasal. There is still a race condition
11206 on hosts that predate Posix 1003.1-1992, but we can't help this.
11207 Don't mishandle weird characters like space on pre-Posix hosts.
11208 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11209 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11210 AC_PROG_MKDIR_P from AS_MKDIR_P.
11211 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11212 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11213 earlier editions are not (including Automake 1.8.3).
11214 Do not suggest mkinstalldirs for thread-safety.
11215 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11216 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11217 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11218 presence of special characters and race conditions.
11219 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11220 in Autoconf's name space.
11222 2006-05-10 Bruno Haible <bruno@clisp.org>
11223 and Paul Eggert <eggert@cs.ucla.edu>
11225 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11226 from Automake with minor changes.
11227 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11229 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11231 * config/install-sh: Update to Automake CVS version, as follows:
11232 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11233 * lib/install-sh: Simplify the expr implementation of dirname.
11234 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11235 * lib/install-sh: Handle --, and diagnose unknown options.
11237 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11239 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11240 `./autom4te' to create `./testsuite', since the `all' target
11241 will ensure its presence, but `installcheck' should not create
11242 the uninstalled wrappers.
11244 * tests/torture.at (Unusual Automake input files): Skip if we
11245 detect automake < 1.8.
11247 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11249 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11250 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11251 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11254 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11256 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11257 munge (multiple) white space and other oddities.
11258 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11259 single quotes in variable assignment.
11260 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11261 and similar failures by adding multiple spaces, tabs, and other
11262 special characters.
11263 Report and different test suggested by Francesco Romani
11264 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11266 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11267 single quotes, we only need to search for single quotes; this
11268 both simplifies the search pattern, and makes us less
11269 susceptible to `echo' variations for arguments not containing
11271 (_AC_ARG_VAR_VALIDATE): Likewise.
11273 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11275 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11276 `$*' and IFS concatenation issue with traditional shells and
11277 bash-2.04. Report by Seanster@Seanster.com.
11279 2006-05-03 Bruno Haible <bruno@clisp.org>
11281 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11282 precisely which Mac OS X versions have the od problem.
11284 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11286 * doc/autoconf.texi: Use @option systematically.
11288 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11289 and Bruno Haible <bruno@clisp.org>
11291 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11293 (Integer Overflow): Mention the special case of integer division
11296 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11298 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11299 traditional shells like the Solaris one that do not use the
11300 first IFS character for assembling `$*'.
11301 Prompted by a related report from autoconf_bug@nro.ca.
11303 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11304 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11306 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11307 Mention more problems with the -e option.
11309 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11312 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11314 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11315 in URLs to improve DVI formatted output (requires texinfo 4.6).
11316 (System Services, Systemology, Shellology): Likewise.
11317 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11320 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11322 (Runtime): Fix macro argument names to match description:
11323 `action-if-found' -> `action-if-true' and similarly.
11324 (Obsolete Macros): Likewise.
11325 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11326 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11327 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11329 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11331 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11334 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
11337 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11340 /bin/sh set unsorted output.
11341 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
11342 * tests/local.at: Likewise.
11344 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11346 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11347 (Integer Overflow, Null Pointers, Buffer Overruns):
11348 (Floating Point Portability, Exiting Portably): New sections.
11349 (Writing Test Programs): Fix some langauge. Recommend exiting
11350 with status 1, not merely nonzero. Clarify exit declaration.
11351 (Run Time): Move C exit status stuff to new Exiting Portably section.
11352 (Systemology): Mention Posix and levenez. Update v7 reference.
11353 (Portable Shell): Mention the Posix shell.
11355 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11357 * bin/autoconf.as (me): Replace by as_me.
11359 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11362 since as_me isn't set yet.
11364 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11366 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11367 a few minor bugs in this area.
11369 * doc/autoconf.texi (Programming in M4sh): Comment out the
11370 documentation of AS_BASENAME, for now.
11371 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11372 (Limitations of Builtins) <basename>: Do not refer to
11374 * bin/autoconf.as (me): Don't use AS_BASENAME.
11375 (dir): Remove the unused variable.
11376 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11377 AS_DETECT_REQUIRED. All uses changed.
11378 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11380 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11381 (AS_BASENAME): Use "basename --" to protect against leading "-".
11382 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11383 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11384 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11385 (_AS_DIRNAME_PREPARE): Likewise.
11386 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11387 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11388 (AS_DIRNAME): Use "dirname --".
11390 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11392 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11393 of "run time" and "run-time" changed to "runtime", for consistency.
11394 * lib/autoconf/fortran.m4: Likewise (in comment).
11395 * lib/autoconf/functions.m4: Likewise.
11396 * lib/autoconf/general.m4: Likewise.
11397 * lib/autoconf/headers.m4: Likewise.
11399 * doc/autoconf.texi (Run Time): Document the exit status situation
11400 with more accuracy and detail.
11402 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11404 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11405 Archive is not officially `GNU' any more. Update URL.
11406 (Defining Directories): Likewise
11407 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11409 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11411 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11412 newline from the `trap' code to finish `config.log'; the NetBSD
11413 /bin/sh resets the exit status after an empty command, as
11414 documented in doc/autoconf.texi.
11415 Reported by Dalibor Topic <robilad@kaffe.org>.
11417 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11419 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11420 Suggested by Bruno Haible.
11422 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11424 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11425 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11426 Instead, just list the shells that we know work.
11427 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11428 changed. Be more cautious about the _cv_ variable.
11429 * tests/tools.at (Syntax of the shell scripts): Check the
11430 _cv_ variable once, at first, to avoid an internal autoconf error
11431 when sh -n does not work.
11433 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11435 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11437 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11439 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11440 use ">&-" since we're only 99.999% sure that this is portable,
11441 and since the MinGW bug is fixed in a different way.
11442 * lib/autotest/general.m4 (AT_INIT): Likewise.
11444 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11446 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11447 before opening config.log, to avoid hitting a bug on MinGW.
11449 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11451 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11452 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11453 This works around a MinGW bug reported by Eric Paire.
11454 Make sure that all writes to the log file append to it,
11455 rather than possibly losing data.
11456 * lib/autotest/general.m4 (AT_INIT): Likewise.
11458 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11460 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11463 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11467 * configure.ac (AC_INIT): Bump to 2.59d.
11469 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11473 * Makefile.maint (news-date-check): Do not require a leading `*'
11474 before the release date in NEWS.
11476 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11477 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11479 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11480 the instantiated file do not contain the string 'datarootdir'
11481 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11482 @mandir@, replace the reference '${datarootdir}' by the value.
11483 * tests/torture.at (datarootdir workaround): New test.
11484 * NEWS: Advertise this temporary fixup.
11485 Based on a patch by Bruno Haible, reported and analyzed by
11486 Paul Eggert and Noah Misch.
11488 2006-04-12 Eric Blake <ebb9@byu.net>
11490 * tests/autotest.at (Debugging a failed test): Fix comment.
11492 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11494 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11495 all the changes since 2006-04-07.
11497 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11499 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11500 succeeded, but `ln -s file dir' failed, take care to remove the
11501 leftover target before the next test, to prevent its spurious
11502 failure; also make sure `ln file dir' works before selecting it.
11503 Thanks to Keith Marshall for pointing this out.
11506 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11507 assignments in `at_debug_args', so that we put them correctly
11508 in the `run' script.
11509 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11510 Reported by Eric Blake.
11512 2006-04-11 Eric Blake <ebb9@byu.net>
11514 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11515 top-level tests after micro-suite has been run. Used in...
11516 (Debugging a successful test, Debugging script and environment),
11517 (Debugging a failed test): ...these new tests. The first of these
11519 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11520 macro, split out from...
11521 (AT_INIT): ...here, so that using -d also generates a run script.
11522 Document that -d inhibits top-level logging.
11523 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11524 inhibits top-level logging; debug scripts are created.
11526 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11528 * tests/autotest.at (Empty test, Empty check): New test to check it.
11530 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11533 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11535 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11536 the files if a problem appears. Make the empty *.at files
11537 read-only, too. Proposed by Ralf Wildenhues.
11539 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11541 * config/Makefile.am: Add comment to force updated Makefile.in.
11543 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11544 space only patch to this file, this patch causes the Makefile.in
11545 files that include freeze.mk to be updated, and thus have a
11546 newer time stamp again, which in turn makes a pristine CVS
11547 checkout have correct time stamps.
11549 * Makefile.maint (cvs-sv): New macro, to be used..
11550 (config.guess-url_prefix, config.sub-url_prefix)
11551 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11552 point to CVS text checkout of Gnulib files.
11553 (copyright-check): Bump current year.
11554 (announcement): Do not hard-wire `./announce-gen'.
11555 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11557 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11559 (wget_files): Update config.guess, config.sub, texinfo.tex by
11560 `wget-update', now that their URLs work again.
11562 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11564 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11565 Problem noted by Paul D. Smith.
11567 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11569 * doc/autoconf.texi: Remove unused words from word list.
11570 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11571 .x-sc_trailing_space: New files.
11573 * doc/standards.texi: Sync from gnulib.
11575 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11576 `LIBOBJDIR' as experimental.
11578 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11579 with a target directory; it's internally implemented as `cp'
11580 anyway, but since Autoconf advertises the possibility to use
11581 a target directory when LN_S is `ln -s', we need to find out.
11582 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11583 analyzed by Keith Marshall <keith.marshall@total.com>.
11587 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11589 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11590 confdefs.h as-is. In general, if it has backslash-newline or the
11591 like, then it doesn't work either to sort or to remove empty
11594 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11596 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11598 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11600 * lib/autom4te.in (Automake-preselections): Preselect
11603 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11605 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11606 apostrophe within a single-quoted string, as this is the usual
11607 tradition and is easier to read than '"'"'. Don't rely on the
11608 shell treating "$/" like '$/'. Use a more-consistent indenting
11609 style for the trap.
11611 2006-04-09 Eric Blake <ebb9@byu.net>
11613 * tests/autotest.at (Backquote command substitution),
11614 (Multiline backquote command substitution): Remove mistaken
11615 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11617 (Parenthetical command substitution, Multiline parenthetical
11618 command substitution): here.
11620 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11622 Import macros from gnulib (often changing their name).
11624 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

11704 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11705 * lib/autotest/general.m4 (AT_INIT): No need to give three

11753 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11754 whether `set' quotes correctly: redirect stderr of the tested
11755 `set', and use a subshell, for Ultrix; use `sed' instead of
11756 `grep' for zsh `set' which may write binary output; match only
11757 at the beginning of a line, to avoid false positives.
11758 In order to avoid false positives by unrelated variables with
11759 multiline content, put the dump algorithm in a subshell and
11760 unset all variables containing newlines (except some which are
11761 special to the shell). Warn about cache variables that are

11808 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11809 (AC_CONFIG_COMMANDS): Do not do so here.
11810 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11811 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

11818 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

11877 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11878 Use 'comm' rather than N instances of grep; this also fixes a bug

11974 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11975 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11976 no longer needed) by libtool. Make it a cache check.

11978 copied here by mistake.

12758 comparing its address. Intel's interprocedural optimization was

12810 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12812 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12813 calls, so that the final expansion of this macro is shorter.
12814 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12815 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12816 the cleanup there. Use AS_VAR_* macros, to be more general.

12868 Update limitations about when to call AC_CONFIG_HEADERS.
12869 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12870 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12871 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12872 ``Configuration Actions''; fix their index entries.
12874 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12875 options correctly. Process N-M as M-N if M is smaller than N.
12876 Process ranges correctly so that N-N will run only N.
12877 Sort and uniquify the tests that will be run. If there is more
12878 than one test, reinsert the banners for the tests.

12884 before passing the macro name to AH_TEMPLATE.

12909 When building in place, set srcdir="."; suggested by Tim Van Holder.
12911 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12912 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12913 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12914 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12915 does not mean "no --srcdir option".
12917 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12919 * tests/autoscan.at (autoscan): New file.

12926 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12928 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,

12931 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12933 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

12946 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12947 "<tab>" in comment, so that the point is understandable.
12949 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12951 Rewrite substantial part of lib/autoconf/status.m4.
12952 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12953 and CONFIG_COMMANDS are not processed in four separate loops.
12954 Instead, there is one main loop. This alows that the common code
12955 is expanded only once, thus config.status (and configure) is smaller.
12957 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12958 the AC_LIST_FILES and cousins macros are no longer used.
12960 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12961 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12962 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12963 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12964 contain the initialization, nor the for loop, nor the associated
12965 commands; all these go to ...
12966 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12967 _AC_OUTPUT_CONFIG_STATUS.
12968 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12969 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12970 (_AC_OUTPUT_FILE): The creation of the sed script ...
12971 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12972 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12973 _AC_OUTPUT_MAIN_LOOP.

12989 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12990 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12991 this didn't belong to the `config commands' section.
12992 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12993 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12994 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12995 to the `config commands' section either.

13008 Several unrelated small changes:
13010 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13011 parameter to AC_DIAGNOSE.
13012 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13013 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13014 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13015 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13016 with AU::AC_OUTPUT.
13017 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13018 in AC_OUTPUT doesn't double-quote it either.
13019 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

13046 (AC_ARG_VAR): ... here.
13047 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13050 Keep a list of all precious variables and process them with one simple
13051 for loop, instead of expanding all commands, or, OTOH, complicated
13052 processing of output of "set".

13058 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
13060 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13061 its value to shell variable ac_precious_vars and call
13062 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13063 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13064 _AC_ARG_VAR_VALIDATE.

13085 They are generated by the Tru64 v5.1B shell.
13087 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13089 Fix my changes from 2005-07-01; reported by Noah Misch.
13090 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13091 description, the macro now accepts only a single tag.

13094 Fix cases when the varsions of Autoconf and Autotest don't match.
13095 Reported by Noah Misch.
13096 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13097 at_top_builddir, for compatibility with older autotest.
13098 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix

13104 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

13109 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13110 sed substitution command, so that we allow | in program prefixes

13114 configure_input, top_builddir, srcdir, etc.
13115 * lib/autotest/general.m4 (AT_INIT): Likewise, for

13120 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13121 for loop over config.site files using `set', to allow
13122 directory names containing IFS characters.
13124 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13126 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13127 directories with weird names. Apparently some people like living

13132 2005-07-01 Stepan Kasal <kasal@ucw.cz>

13148 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13149 document to output the default config_* lists to config.status.
13150 Don't recognize option --file, if the functionality is not there.
13151 Likewise for --header; moreover, recognize --he and --h as shortcuts
13152 for --help in that case.
13154 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13155 matches the order of execution. No code changed.

13176 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13177 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13178 (AC_SUBST): Call it.
13179 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13180 the directory specific variables; but don't call it for configure_input.
13182 2005-06-28 Derek Price <derek@ximbiot.com>
13184 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13187 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13189 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13190 directory have inherent problems with special characters like spaces,
13191 due to limitations in Make syntax. Problem reported by Alexandre
13193 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13194 Also, fix Tru64 porting problem with shell patterns,

13208 variable into diagnostic. Make the diagnostic an error, not a warning,
13209 because we really don't support spaces and suchlike in dir names.
13210 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13211 Don't worry about backslashes in srcdir; it can't happen now.

13222 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13224 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13225 that '\|' is not allowed in BREs; recommend using newline separated

13238 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13239 b, t, r, w commands require single space, while : cannot have any.
13240 (Special Shell Variables): Fix sed code this in the example.
13241 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13242 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13244 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13245 expand to the empty list. Don't use two pairs of m4_changequote,
13246 it's not necessary.
13248 2005-06-20 Derek Price <derek@ximbiot.com>
13250 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13252 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13254 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13255 * doc/autoconf.texi:
13256 Don't mention Solaris versions so much, if a
13257 problem is common to all extant versions of Solaris. Say "SunOS
13258 4" instead of "SunOS" for SunOS 4.
13259 (awk): Mention more of the limitations of traditional Awk.
13260 (cat): Don't talk about cat -v.

13273 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13274 Use shell builtins rather than 'expr', to work around expr bug.
13276 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13278 * doc/autoconf.texi: "filesystem" -> "file system".
13279 "behaviour" -> "behavior".

13288 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13289 to update the man page. That way, we don't have to check in new
13290 man pages every month.
13292 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13293 quotes and backslashes. Patch from Derek Price.

13302 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13303 -u, since it outputs chatter if the input files are the same.
13304 Problem reported by Ralf Menzel.
13306 2005-06-08 Derek Price <derek@ximbiot.com>
13308 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13309 renaming them since they are about to be redefined anyhow.
13311 2005-06-08 Derek Price <derek@ximbiot.com>
13313 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13314 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13315 Move m4_undefine to alphabetical order.
13317 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13319 * README: Recommend GNU M4 1.4.3 or later.
13320 * doc/autoconf.texi (Introduction): Likewise.
13321 Reword to avoid some formatting glitches.
13322 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13323 Clarify explanation of HP compiler bug.
13324 Redo example output tp match current CVS snapshot.
13325 Use @example.org in email addresses when the examples
13326 might get inadvertently cut-and-pasted into user code.
13327 Remove example of autom4te usage that doesn't seem to work now.
13328 Use modern AC_INIT (except when the example is meant to be
13329 shown with Autoconf 2.13).
13330 Update ksh info for Solaris 9 and later.
13332 Modernize description of Automake versions a bit.
13333 Don't claim a future version of Autoconf is near.

13339 follows its own advice about quoting better.
13340 Reword to avoid some formatting glitches.
13341 * doc/installt.exi: Reword to avoid some formatting glitches.
13343 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13344 Tru64 ksh pattern matching bug. Reported against Libtool by
13345 Albert Chin <libtool@mlists.thewrittenword.com> and
13346 Nicolas Joly <njoly@pasteur.fr>.
13348 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13350 m4_cdr of one-member list was [[]] (one-member list containing an
13351 empty string) instead of [] (an empty list. Callers were skewed to
13352 match this misbehaviour. As a consequence of this:
13353 - m4_foreach([x], [], [foo]) expanded to `foo', while
13354 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13355 This bug has been fixed:
13357 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13358 expand to an empty string; print error msg if called without
13360 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13361 misbehaviour; handle [] and [[]] correctly.
13363 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13365 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13366 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13367 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13369 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13371 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13372 swallow records with more than 99 fields.
13373 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13374 parse the long line.
13376 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13378 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13379 swallow literals longer than 399. Reported by Ralf Wildenhues.
13380 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13381 to workaround this limitation.
13383 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13385 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13386 to gfortran, and make these the first two compiler names
13387 checked (following the general autoconf preference for gcc).
13389 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13391 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13392 (DISTCLEANFILES): Remove $(check_SCRIPTS).

13397 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13398 expression of unbounded size when processing the --list
13399 option. This runs afoul of a limit of 399 bytes per regular

13405 * doc/autoconf.texi (Particular Headers): Reword example
13406 for multiline stdbool replacement.
13407 (Setting Output Variables): Reword text a bit. Don't
13408 give all the details about |#_!!_#|.
13409 Reword description of line replacement.
13411 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13413 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13414 now contain newlines, and substituted files must be referenced on
13415 a line alone; the sed scripts to substitute them are now very
13417 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13418 commands can be put in a sed script portably.
13419 * doc/autoconf.texi (Setting Output Variables): Document above
13420 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13421 use of multiline substitution.
13422 * tests/torture.at: No longer expect substitution of newline to fail.
13424 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
13426 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
13427 From Ralf Menzel (trivial change).
13429 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13431 * tests/local.at: Don't attempt to check for negated character
13432 classes in shell scripts. The test was too brittle.
13434 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13436 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13437 * doc/autoconf.texi (Limitations of Builtins): Document this
13440 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13442 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13443 common code; used in many places in the tree.
13444 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13445 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13447 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13449 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13450 messages when ac_unique_file is not found.
13451 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13452 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13453 commands, for consistency with AC_MSG_ERROR and such.
13455 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13457 * bin/Makefile.am: Merge the two rules for creating scripts.
13459 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13461 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13462 obsolete; it was never documented.
13463 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13465 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13467 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13468 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13469 (ac_top_builddir): ... this ...
13470 (ac_top_build_prefix): ... to this; the old name is also kept, for
13471 backward compatibility.
13472 (ac_top_builddir_sub): New variable, without the trailing slash,
13474 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13475 * doc/autoconf.texi (Configuration Actions): Rename
13476 ac_top_builddir to ac_top_build_prefix.
13477 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13478 at_top_builddir to at_top_build_prefix.
13479 * lib/autotest/general.m4 (AT_INIT): Likewise.
13481 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13483 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13486 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13488 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13489 argument to m4_foreach. I guess it was necessary in the past,
13490 but I think it's a no-op now.
13492 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13494 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13495 ``cat <<_ACEOF'' commands to one.
13496 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13497 * lib/autoconf/status.m4: On various places, use expr instead of
13499 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13500 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13501 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13503 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13504 the wrong patterns between ``case'' and ``esac.'' The previous
13505 code had false positives.
13507 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13509 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13552 2005-05-13 Stepan Kasal <kasal@ucw.cz>
13554 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
13556 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
13557 enough arguments, similarly as in m4_bpatsubsts.
13559 2005-05-12 Stepan Kasal <kasal@ucw.cz>
13561 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
13564 2005-05-11 Stepan Kasal <kasal@ucw.cz>
13566 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
13567 for absolute directory names in one loop.
13568 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
13569 abbreviations of --version and --debug.
13571 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13573 * doc/autoconf.texi (Autoconf Language): Be more precise about
13574 quoting rules. Problems noted by Stepan Kasal.
13575 Also, throughout this document, be more careful about white space.
13576 "blank", "white space", and "space" all have different meanings
13577 and we should be careful to say what we mean.
13579 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13581 Fix C++ related problems reported by Werner Lemberg.
13582 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
13583 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
13584 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
13585 avoid problems with C++ and throw.
13586 * tests/compile.at: .cpp, not .cc.
13588 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
13590 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13592 * doc/autoconf.texi (Generic Functions): Typos.
13594 2005-05-02 Gary V. Vaughan <gary@gnu.org>
13596 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
13597 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
13598 set by latest automake.
13600 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13602 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13603 outputs 0 on GNU/Linux these days.
13605 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13607 * doc/autoconf.texi (Autoconf Language): Add more description
13608 about quoting heuristics.
13609 (Limitations of Builtins): Describe "set -" problems.
13611 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13613 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13616 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13617 by AC_DEFINE; it was a mistake.
13618 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13620 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13622 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13624 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13626 * doc/autoconf.texi (External Software): Quadrigraphs are not
13627 processed correctly in AS_HELP_STRING; avoid this in the examples.
13628 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13629 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13630 comment and reduce m4_default([foo], []) to [foo].
13631 (m4_strip): Update the explanation.
13633 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13635 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13636 Remove core.conftest.* too; it's generated by Tru64 5.1.
13637 Problem reported by Jennis Pruett.
13638 * lib/autoconf/functions.m4
13639 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13640 Don't bother to remove core files; AC_RUN_IFELSE should do that
13643 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13645 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
13647 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
13649 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
13650 Report from Horst Wente.
13652 2005-04-15 Stepan Kasal <kasal@ucw.cz>
13654 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
13657 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
13659 * doc/autoconf.texi (External Software, Package Options): Add
13660 examples showing how to implement --with-* and --enable-* options.
13662 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13664 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13665 as well as configure.in. Problem reported by Gregorio Guidi.
13667 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13669 * doc/autoconf.texi (Particular Functions): Use gnulib's current
13670 pattern for alloca snippet.
13672 2005-04-04 Stepan Kasal <kasal@ucw.cz>
13674 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

13680 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
13682 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
13683 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13685 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13687 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13688 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13689 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13690 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13691 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13693 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13695 * NEWS: The configure command now warns you if you attempt to use
13696 a directory whose name contains a special character like space,
13698 * doc/autoconf.texi (Installation Directory Variables): Allow
13699 "," in file names. Do not use \@; it's not a portable regexp.
13700 * bin/Makefile.am (edit): Likewise.
13701 * lib/Makefile.am (edit): Likewise.
13702 * tests/Makefile.am (edit): Likewise.
13703 * tests/semantics.at: Likewise.
13704 * tests/torture.at: Likewise.
13705 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
13706 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13707 * doc/autoconf.texi (File System Conventions): Warn about
13708 unportable file names.
13709 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13711 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13712 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13713 ac_pwd, and quote srcdir.
13714 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13716 * doc/autoconf.texi: Fix some systematic formatting problems.
13717 ".)" needs a following @: if not at the end of a sentence, and
13718 similarly for "!)". "etc." should be preceded by a comma.
13719 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13721 2005-03-22 Bruno Haible <bruno@clisp.org>
13723 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13724 argument is often called 'build-aux'.
13726 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13728 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13729 macro AC_TRY_LINK is obsolete.
13730 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13733 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13735 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13736 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13737 from a Common Lisp's `cl'.
13738 (AC_PROG_CXX): Behave according to the documentation: don't
13739 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13740 make the variable CCC precious; use `cl.exe', not `cl'.
13742 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13743 Alexandre Duret-Lutz <adl@gnu.org>
13745 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13746 /dev/null, as "configure" shouldn't read stdin, and this insulates
13747 us from problems (e.g., when testing for "cl"). Also, do this
13748 redirection before invoking "hostname" or "uname", and keep the
13749 original input stream available via...
13750 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13751 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13752 bother with "</dev/null" since it's now done at the top of
13754 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13755 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13756 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13757 * doc/autoconf.texi (File Descriptor Macros): New section.
13758 (Printing Messages): Mention it.
13759 * tests/base.at (Input/Output): New test.
13761 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13763 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13764 newline if neither \c nor -n work, as that would output two
13765 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13767 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13769 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13770 This causes that any required macros inside will get before the if.
13771 * doc/autoconf.texi (autom4te.cache): A typo.
13773 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13775 Undo previous change, except keep the change to
13776 lib/autoconf/programs.m4 that replaced grep with shell
13777 pattern-matching. This is because net-snmp configure reads stdin.
13778 Reported by Noah Misch.
13780 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13782 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13783 from /dev/null, as "configure" shouldn't read stdin, and this
13784 insulates us from problems (e.g., when testing for "cl").
13785 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13786 before invoking "hostname" or "uname".
13787 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13788 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13789 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13790 "</dev/null" since it's now done at the top of 'configure'.
13791 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13792 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13793 Also, replace grep with shell pattern-matching, to save a process.
13795 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13797 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13798 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13799 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13802 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13804 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13805 grep -q isn't portable. Improve grep -s explanation.
13806 Problem reported by Dan Manthey.
13808 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13810 * doc/autoconf.texi (Special Shell Variables): Clarify
13811 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13813 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13815 * doc/autoconf.texi: Use @acronym for DJGPP.
13816 Fix some @code's that should have been @env's, and vice versa.
13817 Sort environment variable names.
13818 Mention that shells no longer inherit IFS.
13819 Don't recommend PATH_SEPARATOR=';' so strongly.
13820 Mention that $RANDOM might expand to the empty string.
13821 "symlink" and "soft link" -> "symbolic link".
13822 Improve mktemp description (reported by Bruno Haible).
13824 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13826 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13827 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13829 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13832 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13834 * NEWS: Mention AT_COPYRIGHT.

13961 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13962 Update the long comment explaining it.
13964 m4_require no longer writes an ``is required by'' line to the
13965 execution stack. It contains only one bit of non-redundant
13966 information: that the macro was required, not called. And even
13967 this bit is useless in most situations: have you ever met a macro
13968 which both calls and requires the same macro?
13970 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13971 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13980 ``is required by'' messages.

14016 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14018 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14019 Warn about newline stripping in `` and $(). Update Solaris
14021 (Limitations of Builtins): Use expr "X...", not expr "x...", as

14072 (_m4_divert_n_stack): New macro; the expansion is
14073 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14075 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14076 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14077 stored in _m4_divert_diversion or _m4_divert_dump.
14078 (m4_divert_pop): When the parameter is given, compare the symbolic
14079 name with the last diversion pushed on the stack. Previously, the
14080 current diversion was compared with the numeric value of the
14081 diversion given as the parameter.
14082 (m4_require): If the macro hasn't been expanded yet, call ...
14083 (_m4_require_call): this new macro.

14116 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

14299 Suggested by Stepan Kasal.
14301 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
14303 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,

14364 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
14365 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14366 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14367 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
14369 2004-12-07 Stepan Kasal <kasal@ucw.cz>
14371 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

14388 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
14390 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14391 "char c = '\200';" rather than "char c = 0x80;" as the
14392 latter doesn't conform to the strict C standard due to
14393 overflow on signed char hosts.
14395 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14396 to -qlanglvl=ansi. We don't want to disable extensions.

14471 limitations. Reorder paragraphs for clarity.
14473 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>

14507 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14509 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14510 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14511 (trivial change). Problem and patch reported by Andrew Church in:
14512 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14514 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14544 Remove ansi2knr.c; nobody uses it.
14545 (ansi2knr.c-url_prefix): Remove.
14546 (cvs-update): Fix test for failure. I don't know why it ever
14549 * doc/autoconf.texi: Update URLs, some of which went stale.
14550 Use @uref rather than @href.
14552 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14553 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14555 * config/config.guess, config/config.sub, config/elisp-comp,

14566 tests/tools.at, tests/torture.at:
14567 Use "file name" rather than "filename" or "path",
14568 to be consistent with the terminology of the GNU coding standards.
14570 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14572 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14573 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14574 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14575 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.

14578 This isn't a complete fix but it's an improvement.
14580 * bin/autoconf.as (autom4te_options): New var.
14581 Use it instead of appending to AUTOM4TE, so that we can allow
14582 spaces in the build directory's absolute name.
14583 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14584 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14585 AT_CHECK_NOESCAPE): Likewise.

14597 * doc/autoconf.texi (Function Portability): Document isinf and
14598 and isnan. From a suggestion by Kevin Ryde.
14600 * lib/Autom4te/General.pm (END): Return correct exit status even
14601 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14603 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14605 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14606 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14607 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14609 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14611 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

14618 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14620 * lib/autom4te.in (Automake-preselections): Preselect
14621 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14624 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14626 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14628 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14629 Document problem with "`""`" in pdksh POSIX mode.
14631 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14633 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14634 with pdksh, too. Problem reported by Patrick Welche via
14636 * doc/autoconf.texi (Shellology): Note that set -o posix is
14637 useful for pkdsh, too.
14639 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14641 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14642 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14643 Don't fail if ENV or BASH_ENV is readonly.
14644 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14645 etc. are read only. Problem reported by Ludovic Courtes.
14647 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14649 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

14653 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14655 * doc/autoconf.texi (File System Conventions): Warn about
14656 names like "aux". Problem reported by Eric Blake.
14658 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14659 by zero instead of array size, so that we can use any arithmetic
14660 constant expression (instead of requiring an integer constant
14661 expression). This allows us to test expressions like DBL_MAX <
14662 LDBL_MAX, which didn't conform to the C standard using the old
14664 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14665 now that we can do floating-point tests at compile time.
14667 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14669 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14670 and LDBL_EPSILON, as the resulting expression isn't an
14671 integer constant expression and violates the C standard.
14672 Problem reported by Nelson H. F. Beebe. Also, check
14673 for "L" suffix, and check that long double doesn't have
14674 worse range or precision than double, that mixed-mode
14675 arithmetic doesn't generate a diagnostic, that double
14676 constants fit in long double.
14678 2004-06-03 Kevin Ryde <user42@zip.com.au>
14680 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14681 malloc(0) and realloc(NULL,size).
14683 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14686 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14688 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14689 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14692 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14694 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14695 can be rewritten using if-then-else. Suggested by Bruno Haible.

14699 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14700 Problem reported by Stepan Kasal.
14702 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14704 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14705 change). Patch reported by Ralf Wildenhues in
14706 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14708 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14709 function F exists if the compiler and linker let you compile an
14710 expression like (F != 0). Recent versions of GCC optimize away
14711 the reference to F in that case, since every function address must
14712 be nonzero, so the link succeeds even if F does not exist.
14713 Problem reported by Manu in
14714 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14716 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14717 "Unix". Many uses changed.

14723 * lib/autom4te.in (Automake-preselections): Preselect
14724 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14726 2004-05-19 Kevin Ryde <user42@zip.com.au>
14728 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14729 referencing AC_FUNC_STRERROR_R.
14731 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14732 note pessimistic assumption when cross compiling.
14734 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14736 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14737 (until 2004) invoked subcommands with sh -e, contra POSIX.
14738 Reported by Kevin Ryde.
14740 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14742 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14743 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14744 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14745 `test -f " /usr/bin/grep"', which _always_ failed.
14746 (AC_PROG_SED): Ditto bogus PATH fix.
14747 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14748 requires that grep correctly supports _multiple_ `-e' options, rather
14749 than stating only that grep should accept `-e'.
14751 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14753 Port to C99, which requires that 'exit' be declared.
14755 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14756 to ensure that stdlib.h is included.
14757 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14758 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14759 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14760 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14761 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14762 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14763 when using 'exit' in a test; C99 requires that 'exit' be declared.
14765 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14767 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14768 now prefers 'grep' implementations that accept -e.
14769 (Limitations of Usual Tools): Describe problems of traditional
14770 egrep and fgrep with long input lines, and of traditional grep
14772 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14773 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14774 All callers changed. Append /usr/xpg4/bin to the PATH, for
14776 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14777 the user with complaints about multiple -e options.
14778 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14779 Define it with AC_PROG_GREP.
14780 * configure.ac (AC_PROG_GREP): Add.
14781 * lib/freeze.mk (GREP): New macro.
14783 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14785 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14786 a possible candidate only after all others fail, rather than
14787 consulting it first. This improves backward compatibility by
14788 better reflecting the way shell selection occurred in previous
14789 versions of Autoconf, and should help to avoid triggering latent
14790 problems in other packages, such as the one in Automake where zsh
14791 is not handled robustly:
14792 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14793 Although it is not Autoconf's responsibility to work around
14794 problems in Automake, it nevertheless makes sense to avoid
14795 introducing unnecessary incompatibilites.
14797 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14798 Gary V. Vaughan <gary@gnu.org>
14800 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14801 how deeply nested we are when a suitable tool is found, set the
14802 ac_path_TOOL_found flag.
14803 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14804 nested we are in this macro. Break out of all 3 nested loops if
14805 ac_path_TOOL_found is set.
14807 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14809 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14810 of the _AS_PATH_WALK loop too if GNU flavor is found.
14812 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14814 * doc/autoconf.texi (Limitations of Make): Update documentation
14815 for `$<'. New entry `Long lines', based on a report from Simon
14816 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14817 paragraph about DJGPP, based on a mail from Richard Dawe.
14819 2004-04-20 Paul Eggert <eggert@twinsun.com>
14821 * tests/c.at (C keywords): Don't assume that GCC supports
14822 "restrict" and "inline", as sufficiently-old GCC versions do not
14823 (also, GCC configured to be in pedantic C89 mode does not).
14824 Problem reported by Sumit Pandya in:
14825 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14827 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14828 consider -g to work if it generates warnings when plain compiles
14829 don't. Problem reported by Braden McDaniel in:
14830 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14832 * doc/autoconf.texi (Slashes): New section, to document a problem
14833 reported by Jim Meyering in:
14834 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14836 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14837 linker output files before linking, to work around IRIX 6 linker bug.
14838 Problem reported by Rainer Orth in:
14839 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14841 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14843 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14844 best tool so far counter rely on the tool path variable name to
14845 avoid checks for one tool being affected by the results of running
14846 the length check on a previous tool.
14848 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14849 match expression argument, as different greps have different
14850 regular expression flavours.
14851 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14853 (AC_PROG_EGREP): Pass 'EGREP$'.
14854 (AC_PROG_GREP): Pass 'GREP$'.
14856 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14858 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14859 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14861 2004-03-29 Paul Eggert <eggert@twinsun.com>
14863 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14864 Types, Specific Compiler Characteristics, System Services,
14865 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14866 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14867 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

14879 2004-03-28 Paul Eggert <eggert@twinsun.com>
14881 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14882 now defines HAVE_DECL_TZNAME if it is declared, when
14883 HAVE_STRUCT_TM_TM_ZONE is not defined.
14884 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14885 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14888 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14890 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14891 superfluous backslashing of quotes (") in sed expressions;
14892 thanks to Paul Eggert.
14894 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14896 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14897 Fortran compiler is ifort, also added pghpf; thanks to Nelson
14898 H. F. Beebe for the bug report.

14943 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
14944 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

14952 2004-03-03 Paul Eggert <eggert@twinsun.com>
14954 * bin/Makefile.am (edit): Don't use $< in a context where
14955 POSIX doesn't require support for it. Use $@.in instead.
14956 Problem reported by Anthony N. Frasso in
14957 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
14958 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

14966 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14968 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
14969 is not always thread-safe. Report from Nathanael Nerode.

14973 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14974 problem on QNX reported by Stephen Rasku in
14975 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
14977 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
14978 $(m4sh_m4f_dependencies); this removes a FIXME.
14979 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
14980 (MAINTAINERCLEANFILES): Split into pieces,
14981 one per related section. Add $(srcdir)/wrapper.in.
14983 2004-02-09 Paul Eggert <eggert@twinsun.com>
14985 * doc/autoconf.texi (Setting Output Variables): Emphasize that
14986 AC_SUBST provides no portable way to escape literal newlines.
14988 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14989 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14990 Darwin uses -lcrt2.o and there's little point to cataloging all
14991 the system variants. Partial fix reported by Andreas Waechter in:

15008 the behavior of the third argument.
15009 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
15010 correctly the behavior of the third argument. Document
15011 what the three macros that AU_DEFUN defines do. Fix

15019 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
15020 (AS_INIT): Output shell initialization there. Removed optional
15021 parameter. Expand _AS_SHELL_FN_SPY.
15022 (AS_INIT_WITH_SHELL_FN): Removed.
15023 (_AS_SHELL_FN_SPY): New macro.
15024 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

15067 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
15068 2003 (except 1997) to the list of copyright years. This undoes
15069 the 2003-05-22 change, which removed the older years from the list.
15070 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

15076 grep or ggrep program in PATH that accepts as long lines as
15078 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

15081 egrep and fgrep respectively if $GREP -E/-F don't work.
15082 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15083 _AC_PROG_GREP, and AC_PROG_SED.
15084 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
15085 longest input length accepted by a command.

15114 2004-01-26 Paul Eggert <eggert@twinsun.com>
15116 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15117 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15118 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15119 not <inttypes.h>. Problem reported by Tim Mooney in
15120 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15121 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15124 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15125 otherwise "make check" fails because it forbids cmp (I guess
15126 because cmp treats files as binary on DOS-like systems).
15128 * tests/mktests.sh: Update copyright date to 2004, since some tests
15129 have changed in 2004.
15131 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15133 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15134 non-truncating sed or gsed program in PATH.
15135 * tests/acprograms.at: Add it.
15136 * doc/autoconf.texi (Particular Programs): Document it.
15139 2004-01-15 Paul Eggert <eggert@twinsun.com>
15141 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since

15148 * doc/autoconf.texi (Programming in M4sh): Document that
15149 AS_MKDIR_P succeeds if the destination is a symbolic link
15150 to an existing directory.
15151 (Limitations of Usual Tools): Note that mkdir -p might not

15172 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15173 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15174 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15175 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15176 AC_COMPILE_IFELSE, since we now assume our caller invokes
15177 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15178 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15179 of AC_RUN_IFELSE; this avoids the warning mentioned above.

15184 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15185 `"'...'"`, as it's confusing (and I suspect it may not work on
15186 some platforms). The code was incorrect anyway, as it assumed
15187 that \$ evaluated to itself in that context. Reported by
15188 Alexandre Duret-Lutz.

15653 Problem reported by Lars J. Aas in
15654 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15655 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15656 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
15657 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
15659 2003-09-26 Akim Demaille <akim@epita.fr>
15661 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15662 directory for AC_CONFIG_COMMANDS' first argument exists.
15663 This makes valid the invocation of _AC_SRCPATH that follows.
15664 Reported by Eric Sunshine.

15688 The test suite are sometimes assigning timings incorrectly.
15689 Reported by Henk Krus.
15690 Diagnosed by Nicolas Joly.
15692 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15694 Instead of making AT_help a sequence of assignments to grow
15695 $at_help_all, just make AT_help_all be the growing contents of
15696 $at_help_all, and make a single assignment in...
15698 (at_times_skip): Flip the meaning and rename as...

15708 * bin/Makefile.am (edit): Handle '@configure_input@'.
15709 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
15710 (ifnames): chmod -w.
15711 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15712 executables, not bin/ executables! Otherwise all the magic needed
15713 to find non installed files is turned off. This caused a failure
15714 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15715 as found in its environment (sent by tests/autoreconf): pointing
15716 to bin/autom4te that could not find its files.
15717 * tests/mktests.sh: Force the replacement of generated files, for
15718 the sake of "mv" program that are interactive when overwriting a

15727 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15728 Paul Eggert <eggert@twinsun.com>
15730 Trivial change to support GCC's configuration procedure.

15798 2003-09-04 Akim Demaille <akim@epita.fr>

15811 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
15813 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15815 Add support for newer Fortran dialects. The F77 interface is
15816 unchanged, and continues to support Fortran 77. New FC macros
15817 correspond to all the old F77 macros, with output variables FC,
15818 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15819 available dialect, but older dialects can be specified. There are
15820 new macros AC_FC_SRCEXT to set the source extension, and
15821 AC_FC_FREEFORM to accept free-form source files.

15947 2003-08-21 Akim Demaille <akim@epita.fr>
15949 First stab at preserving warnings between calls to autom4te,
15950 including when the cache is used.
15952 There are still several issues: (i) there are too many runs of m4
15953 (one for include, one for warnings, and some more), (ii) warnings
15954 spreading on several lines are not handled gracefully, (iii) the
15955 code meant to have the call stack display for errors does not work
15956 (its handling should move from m4 to autom4te).
15958 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15960 (@preselect): Add m4_warn.
15961 ($exit_status): Remove, use $exit_code.
15962 ($help): Use Autom4te::ChannelDefs::usage.
15963 (&handle_m4): No longer define the m4_warnings.
15964 At each run, extract and report the warnings.
15965 Always cache the result, including if the exit status is on
15966 failure, since if nothing changes, we should result in the same
15967 failure, hence we can use the cache.
15968 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15969 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15971 (m4_warn): Redefine as a do-nothing: it is its invocation that
15972 matters, as warnings are now reported via traces.
15973 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15974 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15975 the latter reveals calls to the former.
15979 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15981 2003-08-21 Akim Demaille <akim@epita.fr>

16001 (&catfile): Remove.
16002 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
16003 * bin/autoscan.in: Adjust.
16005 2003-08-20 Akim Demaille <akim@epita.fr>
16007 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
16008 Reported by Alexandre Duret-Lutz.
16010 2003-08-20 Akim Demaille <akim@epita.fr>
16012 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
16013 * bin/autom4te: Adjust.
16014 In particular, be Autoconf tools are really silent when properly
16015 working, bind the verbosity of the 'note' channel to $verbose.
16016 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
16017 (&xsystem, &contents): Remove, since they are exported by...
16018 * lib/Autom4te/FileUtils.pm: this.

16021 * lib/Autom4te/FileUtils.pm: here.

16119 (trivial change). See:
16120 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

16126 * lib/Makefile.am (autom4te.cfg): Make it read only.
16127 Depend on Makefile since it contains substitutions.
16128 From Paolo Bonzini.
16129 * lib/autom4te.in (args): Add local.at? for Autotest args.
16130 This change was made on autom4te.cfg which is generated.
16131 Reported by Raja R. Harinath.
16133 2003-06-25 Akim Demaille <akim@epita.fr>
16135 * doc/autoconf.texi (Header Portability): sys/mount.h.
16136 From Gareth McCaughan.
16138 2003-06-23 Akim Demaille <akim@epita.fr>
16140 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16141 not all of them. This fixes 1. the fact that when testing
16142 Autoconf there are many many config.log, 2. the incorrect use of
16143 top_srcdir to find config.log.
16144 Don't mix the detailed output of failed test with the summary of
16145 failures. Rather, append detailed log afterwards.
16147 2003-06-23 Akim Demaille <akim@epita.fr>
16149 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
16150 always run: output config.log on $at_group_log.
16152 2003-06-23 Akim Demaille <akim@epita.fr>
16154 * tests/torture.at (#define header templates): Don't use quotes in
16155 C++ comments as it puzzles Emacs' sh font-lock-mode.
16157 2003-06-23 Akim Demaille <akim@epita.fr>
16159 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
16160 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
16161 * tests/atspecific.m4: Rename as...
16162 * tests/local.at: This.
16163 * tests/suite.at: Move the globals into...
16164 * tests/local.at: here.
16165 * tests/Makefile.am: Adjust.
16166 * doc/autoconf.texi (testsuite Scripts): Adjust.
16168 2003-06-21 Kevin Ryde <user42@zip.com.au>
16170 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
16171 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
16172 ensuring we add -std1 for full-ANSI.
16174 * doc/autoconf.texi (hdrindex): New macro.
16175 Add index entries for portability of various standard header files.
16177 2003-06-20 Akim Demaille <akim@epita.fr>

16207 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
16208 (AT_INIT): Support for expected failures.
16210 2003-06-02 Akim Demaille <akim@epita.fr>
16212 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

16219 2003-05-28 Paul Eggert <eggert@twinsun.com>
16221 * NEWS, doc/autoconf.texi (Particular Functions),
16222 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
16223 is the inverse of localtime.
16225 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
16227 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
16228 (handle_exec_errors): New function. Work around $! being
16229 altered by WEXITSTATUS.
16230 (xqx, xsystem): Use handle_exec_errors.
16232 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16234 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16235 Do not call `_exit()', simply modify `$?'.
16236 (xsystem): Reset $! before running system, and check it afterward.
16237 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16238 63 for version mismatches.
16240 2003-05-23 Akim Demaille <akim@epita.fr>
16242 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16243 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16244 the middle of a line).
16245 * lib/m4sugar/m4sugar.m4: Likewise.
16246 Remove useless spaces in comments.
16248 2003-05-23 Akim Demaille <akim@epita.fr>
16250 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
16251 exit 63, so that we (or Automake's "missing") can tell the
16252 difference with a plain failure.
16253 * doc/autoconf.texi (Notices): Adjust.
16255 2003-05-23 Akim Demaille <akim@epita.fr>
16257 * Makefile.am, bin/Makefile.am, config/Makefile.am,
16258 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
16259 White spaces cleanup.
16261 2003-05-22 Jim Meyering <jim@meyering.net>
16262 Paul Eggert <eggert@twinsun.com>
16264 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16265 Remove `#include <stdlib.h>' from the list; we should never
16266 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16267 resulting namespace pollution would cause other tests to fail.
16268 Configure scripts run with some older versions of g++ and HP's
16269 aCC would fail due to such an #include. Problems reported by
16270 Matthew Mueller in <http://bugs.debian.org/120704> and by
16272 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16273 In the test, use the test declaration before including <stdlib.h>,
16274 as that's closer to how it'll be used.
16276 2003-05-23 Akim Demaille <akim@epita.fr>
16278 * doc/autoconf.texi (Header Portability): ucred.h.
16281 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16283 Overhaul Autotest's logging: generate separate log files
16284 in testsuite.dir/NNN/testsuite.log, and append them to
16285 testsuite.log instead of re-running the test verbosely.
16287 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16288 file descriptor, write 0 to at_status_file instead of setting
16289 at_status=0, initialize some new variables (at_status_file,
16290 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16291 to rerun the tests, instead append the at_group_log to the
16292 at_suite_log when a test fails.
16293 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16294 with the AS_MESSAGE_LOG_FD redirected to stdout.
16295 (AT_CLEANUP): save the output status in $at_status_file
16296 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16297 its original place.
16298 (AT_CHECK): since tests are run with a redirected stdout,
16299 and used to be re-run in verbose mode, turn some $at_verbose
16300 into echo, and don't redirect the output of testing stdout
16303 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16304 the name of the debugging directory and information about
16307 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

16424 2003-05-06 Akim Demaille <akim@epita.fr>
16426 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16427 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16428 by aclocal.m4 is changed it might require the importing of another
16429 m4 extension file, i.e., aclocal must be run.
16431 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16432 (&parse_args): Use --force with aclocal if required and supported.

16446 2003-04-29 Derek Price <derek@ximbiot.com>
16448 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16449 seperator with m4_append_uniq(). It doesn't work.
16450 (AT_CLEANUP): Add `;' to end of at_help_all.
16451 (AT_INIT): Allow --keywords to be specified more than once. When
16452 grepping $at_help_all for keywords, use the field and keyword
16453 seperators to ensure a complete keyword match. Alter at_prev handling
16454 to support the new --keywords behavior.
16456 2003-04-27 Karl Berry <karl@freefriends.org>
16458 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16459 align better with others. I also made some of the individual
16460 entries on one line, for brevity and to make it easier for me to
16461 sort my dir-example file in the Texinfo distribution :).

16527 reading the section "Present But Cannot Be Compiled" when the
16528 header causes problems.

16532 * tests/torture.at (Configuring subdirectories): Require aclocal
16533 1.4, otherwise the test fails, as it does support configure.ac.

16606 Tru64 make in the "target lookup" section.
16607 (Automake): Automake 1.5+ no longer requires special tools to be
16608 present on the developer's host.

16624 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16625 to cope with DOS-style absolute paths, when constructing
16628 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16629 When constructing paths with IFS=:, quote the path. If we're
16630 constructing a DOS-style absolute path, we don't want to split it

16653 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16654 format starting with "-".
16656 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16658 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16659 is not portable inside Makefile.
16661 2003-02-20 Akim Demaille <akim@epita.fr>
16663 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

16681 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16682 innocuous variant befor including <limits.h> or <assert.h>. This
16683 works around a bug reported by Albert Chin: HP-UX 11i
16684 (and earlier versions) have a <limits.h> that declares
16685 gettimeofday and many other functions.
16687 2002-12-03 Paul Eggert <eggert@twinsun.com>
16691 * NEWS, configure.ac: Update version.
16693 * doc/fdl.texi: Upgrade to FDL version 1.2.
16695 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16696 nontrivially in main's body, so that f's external declaration is
16697 not optimized away in AIX. This should fix the bug reported by
16699 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16701 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16702 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16703 defined, to support freestanding compilers. This should fix the
16704 bug reported by Momchil Velkov in
16705 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16707 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16708 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16739 Update from masters.
16741 2002-11-14 Akim Demaille <akim@epita.fr>
16743 * Makefile.maint: Sync with Bison, i.e.:
16744 (po-check): Scan .l and .y files instead of the
16745 .c and the .h files that they generate. This fixes the bug
16746 reported by Tim Van Holder in:
16747 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16748 Look for N_ as well as for _. Try to avoid matching #define for
16752 2002-11-14 Akim Demaille <akim@epita.fr>
16754 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16755 From Paul Eggert and Albert Chin-A-Young.
16757 2002-11-14 Akim Demaille <akim@epita.fr>
16759 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16760 From Paul Eggert and Albert Chin-A-Young.

16764 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16765 than assigning in main, to avoid HP cc +O3 optimizing it away.

16769 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16770 option. Process --recheck after parsing all options. Pass -q
16771 option to configure on --recheck.
16772 (AC_OUTPUT): Pass -q from configure to config.status.
16773 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16774 arguments to record.
16775 * doc/autoconf.texi (config.status Invocation): Document
16776 config.status -q option.
16778 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16780 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16781 Makefile.in if Makefile.am exists.
16782 (output): Strip `.am' from Makefiles. Don't
16783 output AC_CONFIG_FILES if no Makefiles were found.

16803 Reported by Ezra Peisach.
16805 2002-11-05 Akim Demaille <akim@epita.fr>
16807 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16809 We _have_ to stop using the old compatibility scheme that tried to
16810 avoid useless backslashes because Libtool 1.4.3 contains a
16811 AC_DEFINE([error_t], [int],
16812 [Define to a type to use for \`error_t' if it is not
16813 otherwise available.])
16814 We _have_ to quote the single quote and backslashes with \. The
16815 old compatibility scheme saw that ` was backslashed, and therefore
16816 did not quote the single quote. Hence before this patch, Autoconf
16817 was not compatible with Libtool.
16819 2002-11-04 Paul Eggert <eggert@twinsun.com>
16821 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16841 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16843 2002-10-31 Bruno Haible <bruno@clisp.org>

16861 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16862 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16863 Make variable, not a shell variable.
16864 Suggested by Bruno Haible.
16866 2002-10-31 Akim Demaille <akim@epita.fr>
16868 * bin/autom4te.in (load_configuration): Reject #args out of any
16871 2002-10-31 Akim Demaille <akim@epita.fr>
16873 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

16891 Problem reported by Bruno Haible.

16897 (Customizing autom4te): s/--cache=/--cache /.
16899 2002-10-29 Akim Demaille <akim@epita.fr>
16901 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

17149 2002-10-22 Akim Demaille <akim@epita.fr>

17206 Because of caching, some files that no longer exist and are no
17207 longer required can still cause errors.
17208 Reported by Alexandre Duret-Lutz.
17210 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17215 (&up_to_date): If a file that was included according to the cache

17230 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17231 if some file was changed instead of `print'.
17232 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17267 From Sam Varshavchik.
17269 2002-10-08 Akim Demaille <akim@epita.fr>
17271 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17272 aclocal invocation, as Gettext macros might not be visible to
17274 Instead of blindly running autopoint, scan configure.ac (not the
17275 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17276 Reported by Paul D. Smith.
17278 2002-10-08 Paul Eggert <eggert@twinsun.com>
17280 Work around problems found when POSIXLY_CORRECT=1 is set.
17281 None of this seems to have anything to do with POSIX, really,
17282 but it's how Perl getopt works.
17283 * bin/autom4te.in (parse_args): Configure GetOpt with
17285 * doc/autoconf.texi (Invoking autom4te):
17286 --warning -> --warnings.

17308 * tests/torture.at (Configuring subdirectories): Be robust to
17309 users who use config.site to require for a cache: in this case,
17310 the two last configure runs, using two different sets of
17311 arguments, trigger a legitimate error.
17313 2002-09-28 Akim Demaille <akim@epita.fr>

17350 (autoscan.list): New target --this file is no longer a source.

17477 2002-09-13 Akim Demaille <akim@epita.fr>

17550 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17551 (ifnames, autoscan, autom4te): Since we don't only depend on
17552 configure.ac variables (such as VERSION etc.), but also on prefix

17554 Reported by Alexandre Duret-Lutz.

17599 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17600 directory names are generally preferable to physical names.
17602 2002-09-02 Akim Demaille <akim@epita.fr>
17604 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17605 Reported by Raja R. Harinath.
17606 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17607 * bin/autoupdate.in: Use error instead of die.
17609 2002-09-01 Paul Eggert <eggert@twinsun.com>
17611 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17612 ordinary shell concatenation rather than echo+tr+sed command that
17613 runs afoul of a long-line-related sed bug in Solaris 8.
17615 * bin/autoheader.in (parse_args): --warning -> --warnings.
17617 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17618 stdout, as traditional "ls" does.
17619 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17620 _AC_COMPILER_EXEEXT_O): Likewise.
17621 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17623 * bin/autoconf.as: Add --prepend-include option. This patch was
17624 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17625 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17627 * bin/autoconf.in, configure: Regenerate.
17629 * doc/autoconf.texi (Special Shell Variables): Mention
17630 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17632 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17633 MAILPATH and set PS1, PS2, PS4 to default values, to work
17634 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17635 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17636 the Autoconf documentation specifies; fall back to "unset" only if
17637 this fails. Use a shell for-loop for this rather than an m4 loop,
17638 to shorten the output script.
17640 2002-08-30 Paul Eggert <eggert@twinsun.com>
17642 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17643 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17644 for the CDPATH problem. Document PWD.
17645 (Limitations of Builtins): Document the problem that "cd $foo" and
17646 "ls $foo" may refer to different directories in shells conforming
17647 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17648 example, since the old example is now out of date.
17650 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17651 FOO" and "ls FOO" talk about different directories; this catches
17652 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17655 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17656 of rolling our own unset.
17657 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17658 in practice we needn't worry about CDPATH if unset doesn't work.
17660 * Makefile.in, aclocal.m4, bin/Makefile.in,
17661 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17662 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17663 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17664 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17665 tests/Makefile.in: Regenerate with Automake 1.6.3.
17667 * config/config.guess, config/config.sub, config/mkinstalldirs:
17670 * configure: Regenerate with self.
17672 2002-08-30 Kevin Ryde <user42@zip.com.au>
17674 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17677 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17679 * bin/autom4te.in (Request::load): Correctly test for "do" read
17682 2002-08-29 Akim Demaille <akim@epita.fr>
17684 * lib/Autom4te/General.pm (&xqx): New.
17685 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17686 hand, which is not portable.
17688 * bin/autom4te.in: Use them.
17689 Use &error instead of die.
17690 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17693 2002-08-17 Paul Eggert <eggert@twinsun.com>
17695 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17696 default list of compilers to try, since it was long ago superseded
17697 by the ksh fc builtin. Suggested by Steven G. Johnson.
17699 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17701 * doc/autoconf.texi (Invoking autom4te): End the option table,
17702 fixing a bug introduced by the previous patch.
17703 (Limitations of Make): Add a 'target lookup' subentry in the
17704 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17706 2002-07-29 Mark D. Roth <roth@feep.net>
17708 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17709 options and use $AUTOM4TE_PATH.
17710 * doc/autoconf.texi: Remove documentation of autom4te
17711 --include-envvar and --site-macro-subdir options and document
17712 use of $AUTOM4TE_PATH.
17713 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17714 arguments from each language section.
17716 2002-07-29 Paul Eggert <eggert@twinsun.com>
17718 * doc/install.texi: Include copyright symbol in copyright notice.
17720 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17722 (AM_MAKEINFOFLAGS): New macro.
17723 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17724 * Makefile.am (INSTALL): Use the new macros.
17725 Use -o rather than --output, since "missing" does not grok --output.
17727 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17729 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17730 comments do not always work. Never trust the exit status of
17733 2002-07-24 Kevin Ryde <user42@zip.com.au>
17735 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17736 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17738 2002-07-23 Paul Eggert <eggert@twinsun.com>
17740 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17741 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17742 apparently treats PATH="nonexistent" as if it contained ".".
17743 Bug reported by Stefan `Sec' Zehl.
17745 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17747 * doc/autoconf.texi (Limitations of Make): Mention the special
17748 handling of the obj/ directory by BSD make.

17768 2002-07-18 Akim Demaille <akim@epita.fr>
17770 * config/config.guess, config/config.sub: Update.
17772 2002-07-18 Akim Demaille <akim@epita.fr>
17774 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

17794 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
17795 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17796 latter was not run.

17800 * lib/Autom4te/General.pm (find_file): Browse the directories in

17866 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
17867 so that Emacs setups GNU style for perl-mode and cperl-mode.
17869 2002-06-27 Paul Eggert <eggert@twinsun.com>
17871 * config/install-sh: Quote $src. Prefer || to test's -o option,
17872 as per "Limitations of Builtins".
17873 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
17874 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
17876 * tests/mktests.sh: Use grep instead of fgrep, as per
17877 "Limitations of Builtins".
17879 2002-06-15 Paul Eggert <eggert@twinsun.com>
17881 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
17882 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
17883 so that we consistently test the just-built programs.
17884 * tests/wrappl.as: Likewise.
17886 2002-06-12 Paul Eggert <eggert@twinsun.com>
17888 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
17889 name, so that symlinks to 'autoconf' work properly. Bug reported
17891 * bin/autoheader.in (AUTOM4TE): Likewise.
17892 * bin/autoreconf.in (autoconf, autoheader): Likewise.
17893 * bin/autoscan.in (autom4te): Likewise.
17894 * bin/autoupdate.in (autom4te): Likewise.
17896 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
17897 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
17900 2002-06-11 Andreas Schwab <schwab@suse.de>
17902 * doc/autoconf.texi: Add more dir entries.
17904 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
17906 * bin/autom4te.in ($cache): Don't define using `$me', the name
17907 of the cache should not depend on the name under which autom4te
17910 2002-06-07 Akim Demaille <akim@epita.fr>
17912 * tests/tools.at (autoconf: forbidden tokens, basic)
17913 (autoconf: forbidden tokens, exceptions): Adjust to the change of
17914 words in autom4te.in.
17916 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
17918 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
17919 _AC_LANG_PROGRAM_C_F77_HOOKS.
17921 2002-06-07 Akim Demaille <akim@epita.fr>
17923 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
17925 (AC_REPLACE_FNMATCH): this.
17926 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,

17929 2002-06-07 Akim Demaille <akim@epita.fr>
17931 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
17932 Rosetta Stone for Unix.
17934 2002-06-07 Akim Demaille <akim@epita.fr>
17936 * bin/autom4te.in (warn_forbidden): When rejecting a token,
17937 suggest m4_pattern_allow.
17938 Suggested by Adam J. Richter.
17940 2002-06-07 Akim Demaille <akim@epita.fr>
17942 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

17956 2002-06-06 Paul Eggert <eggert@twinsun.com>
17958 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
17959 if ln doesn't work.
17961 * doc/autoconf.texi (Configuration Links): Likewise.
17962 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
17964 2002-06-05 Paul Eggert <eggert@twinsun.com>
17966 * config/config.guess, config/config.sub, config/texinfo.tex:
17967 Update from masters.
17969 2002-05-29 Paul Eggert <eggert@twinsun.com>

17984 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
17985 * doc/autoconf.texi (Particular Programs): Document them.

17989 2002-05-27 Paul Eggert <eggert@twinsun.com>
17991 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
17992 * NEWS, doc/autoconf.texi (Particular Types): Document it.
17993 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
17994 instead of AC_MBSTATE_T, which never existed.
17996 2002-05-23 Akim Demaille <akim@epita.fr>
17998 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
17999 version of Autoconf that is discussed.
18001 2002-05-22 Paul Eggert <eggert@twinsun.com>
18003 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
18004 from the default list of compilers to try. Suggested by
18006 * NEWS: Document the above.
18007 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
18009 2002-05-17 Paul Eggert <eggert@twinsun.com>
18011 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
18012 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
18013 This improves on an earlier suggestion by H. Peter Anvin.
18015 2002-05-16 Paul Eggert <eggert@twinsun.com>
18017 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18018 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18019 Both macros now accept an optional source-dir arg.
18020 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18022 * NEWS: Document this.
18023 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18025 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18026 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18027 not for GNU extensions; this undoes part of the 2000-11-03 change,
18028 reverting to 2.13-compatible behavior.
18029 Add new optional argument DIR.
18030 (AC_FUNC_FNMATCH_GNU): New macro.
18032 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
18034 2002-05-08 Paul Eggert <eggert@twinsun.com>
18036 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18037 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18038 and it causes a 'test' syntax error if it fails.
18039 Bug reported by Stephen Gildea.
18041 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18042 If prototypes are supported, use them to check this at compile-time,
18043 instead of trying to check it at run-time. If we must do a run-time
18044 check, assume that setvbuf is standard when cross-compiling, as
18045 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18046 Bug reported by Paul D. Smith.
18048 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18049 argument specifying location of getloadavg.c. This removes a
18050 FIXME. This idea was taken from Jim Meyering's implementation in
18052 * doc/autoconf.texi (Particular Functions): Document this.
18053 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18054 that's what the code does; this fixes a bug reported by
18057 2002-05-03 Akim Demaille <akim@epita.fr>
18059 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18060 autopoint instead of gettextize.
18061 ($uses_alocal): Rename as...
18062 ($uses_aclocal): this.
18063 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18064 Suggested by Bruno Haible.
18066 2002-05-03 Akim Demaille <akim@epita.fr>
18068 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18070 2002-04-29 Paul Eggert <eggert@twinsun.com>
18072 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18073 files to be 1 second older; just set them to be the same time.
18074 Also, sleep 1 second after the first aclocal, to work around
18075 problems with sub-second time stamps on the input files.
18077 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18079 * doc/autoconf.texi: Mention "set -e -x" lossage
18080 under node "Limitations of Builtins".
18082 2002-04-29 Akim Demaille <akim@epita.fr>
18084 * doc/install.texi: Better wording for setting variables when
18086 From Christian Cornelssen.
18088 2002-04-29 Akim Demaille <akim@epita.fr>
18090 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18091 of lack of $LINENO support, then the test will compare the $LINENO
18092 in testsuite vs. the lineno in the test file. This is wrong, of
18094 Be sure to protect it.
18095 Reported by Patrick Welche.
18097 2002-04-25 Akim Demaille <akim@epita.fr>
18099 * doc/autoconf.texi (Obsolete Macros): Typo.
18100 Reported by Vladimir Volovich.
18102 2002-04-25 Akim Demaille <akim@epita.fr>
18104 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18105 than some of the input files, hence, on the second run of aclocal,
18106 if some of its input are younger, make them older.
18107 Suggested by Paul Eggert.
18109 2002-04-25 Akim Demaille <akim@epita.fr>
18111 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18117 and ac_subst_vars be sh variables containing the list of
18118 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18120 (_AC_INIT_PREPARE): Use them to log them.
18121 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18122 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18123 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18124 _AC_SUBST_FILES and _AC_SUBST_VARS.
18125 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18127 2002-04-24 Akim Demaille <akim@epita.fr>
18129 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18130 autoheader, so that automake does not complain about a missing
18131 config.h.in that was to be created.
18133 2002-04-23 Akim Demaille <akim@epita.fr>
18135 * bin/autoheader.in (parse_args): --warning takes an argument.

18185 Minor spelling and grammar fixes.
18187 * doc/autoconf.texi: Follow the outline suggested in the GNU
18188 Sample Texts sections of the Texinfo 4.2 manual. Most
18189 importantly, this makes sure that the copyright notices appear in
18190 all output formats. You probably need Texinfo 4.2 to generate

18194 arguments in cases where this matters.

18217 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
18219 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
18220 from aclocal.m4 too.
18222 2002-04-12 Akim Demaille <akim@epita.fr>

18226 2002-04-10 Akim Demaille <akim@epita.fr>
18228 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18229 workaround for ${1+"$@"}.
18230 * doc/autoconf.texi (Shell Substitutions): Explain it.
18231 From Oliver Kiddle and Peter Stephenson.
18233 Have M4sh perform minimal shell sanitizing.
18235 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18237 (_AS_PREPARE): this new macro.
18239 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18240 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18242 Adjust Autoconf and Autotest.
18244 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18245 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18246 * lib/autotest/general.m4 (AT_INIT): Likewise.
18247 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18248 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18251 Use this M4sh to generate Autoconf's shell scripts.
18253 * tests/wrapsh.as: New, precursor of wrapsh.in.
18254 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18255 on Autotest and M4sh.
18256 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18257 (wrapsh.in): New target.
18258 * bin/autoconf.as: New, precursor of autoconf.in.
18259 (autoconf.in): New target.
18261 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

18264 with indented comments in rules.
18266 2002-04-09 Andreas Schwab <schwab@suse.de>
18268 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
18269 ac_top_builddir when setting ac_abs_top_builddir.

18273 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
18274 (Portable Shell): Cross reference to Systemology.
18276 2002-04-05 Akim Demaille <akim@epita.fr>
18278 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
18279 directories when descending in a SUBDIRS.
18280 Reported by Ezra Peisach.
18282 2002-04-04 Andreas Schwab <schwab@suse.de>
18284 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18285 contains no literal separators.
18287 2002-04-03 Akim Demaille <akim@epita.fr>
18289 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18290 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18291 Use dnl, not the KILL diversion.
18293 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18294 (AC_CONFIG_LINKS): here.
18296 Don't use the KILL diversion, as it kills spurious output, which
18297 results in failures being hidden.
18298 Use m4_defn where appropriate.
18299 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18300 after the second argument.
18302 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18303 syntax, as it is provided by M4sugar.
18304 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
18306 2002-04-03 Andreas Schwab <schwab@suse.de>

18309 expanded if $# <= 2.

18325 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18327 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18328 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18329 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
18330 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
18331 (AC_C_CONST): Same.
18332 (AC_C_INLINE): Same.
18333 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
18334 * doc/autoconf.texi, NEWS: Document.

18343 2002-03-28 Kevin Ryde <user42@zip.com.au>
18345 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18346 to avoid versions of HP C which don't allow that.
18348 2002-03-27 Paul Eggert <eggert@twinsun.com>
18350 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18351 (AS_SHELL_SANITIZE): Invoke it.
18352 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

18362 2002-03-25 Paul Eggert <eggert@twinsun.com>
18364 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18365 as POSIX requires, as it doesn't work with Zsh.
18366 * doc/autoconf.texi (Assignments): Document the problem.
18368 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18370 * doc/autoconf.texi (Limitations of Make): Mention more issue
18371 about VPATH, overriding of macros in sub-makes, and handling of
18374 2002-03-21 Paul Eggert <eggert@twinsun.com>
18376 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18377 problem with here-document buffer boundaries.
18379 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18380 when reinvoking the shell, to work around problems with installers
18381 who put strange things like "cd" commands in their environments.
18383 2002-03-19 Akim Demaille <akim@epita.fr>

18405 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18406 (Limitations of Usual Tools): Add mkdir section.
18408 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18409 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18410 back on AS_DIRNAME to compute prefixes otherwise; this is
18411 roughly what mkinstalldirs does. That way, we need not have
18412 our own filename disassembler. The old disassembler did not
18413 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18415 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18416 Create at_test_all by a series of assignments,
18417 not by a single assignment of a long string. The latter causes ksh
18418 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18419 presumably because of a buffer overrun.
18421 2002-03-14 Paul Eggert <eggert@twinsun.com>
18423 * lib/autotest/general.m4 (at_times_skip):
18424 Renamed from at_times. Now a boolean.
18425 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18426 says 'times: not found'.

18442 Add information about stdint.h and inttypes.h from Paul Eggert.
18444 2002-03-13 Akim Demaille <akim@epita.fr>

18455 2002-03-11 Andreas Schwab <schwab@suse.de>

18458 does not do it if --with-lispdir is given.

18467 subdirectory should exist.
18469 2002-03-08 Akim Demaille <akim@epita.fr>
18471 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18473 2002-03-08 Akim Demaille <akim@epita.fr>
18475 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18476 aliases the actual variables, and modifications of the former
18479 2002-03-08 Akim Demaille <akim@epita.fr>
18481 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18482 because of C-c: have m4 output in tmp files, then mv them.
18484 2002-03-08 Akim Demaille <akim@epita.fr>

18505 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18506 * lib/autoconf/general.m4 (AC_INIT): More informative error
18507 message for LIBOBJ.
18509 2002-03-04 Akim Demaille <akim@epita.fr>

18516 * doc/autoconf.texi (Transforming Names): Equality between target
18517 and host is irrelevant.
18518 (Specifying Names, Canonicalizing): Remove all references to the
18519 backward compatibility hooks. Rather, collect them all into...
18520 (Hosts and Cross-Compilation): this new section.
18521 * doc/install.texi (System Type): Ditto.
18522 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18523 that `--host' implies cross-compilation.
18525 2002-03-04 Akim Demaille <akim@epita.fr>
18527 * doc/autoconf.texi (Evaluation Macros): New.
18528 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18530 (_m4_foreach): Define the variant with immediate evaluation so
18531 that it contains exactly the items, not an expression which
18532 evaluation is the current item.
18533 (m4_re_string, m4_re_word): Don't over quote them.
18535 2002-03-04 Akim Demaille <akim@epita.fr>
18537 Instead of having stacking `shift's evaluated at the end, let
18538 `foreach' loops immediately evaluate them.
18540 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18541 $*. This is the n-th time I change my mind, but hopefully this is
18544 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18546 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18547 it was only a hack for m4_text_wrap.
18548 (m4_car2): Remove, replaced by...
18550 (_m4_foreach): Adjust.
18551 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18552 m4_bpatsubst for clarification.

18603 Fix Autoconf PR/207:
18604 AC_PREFIX_PROGRAM fails with dashed program names
18606 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18607 variable when looking for the prefix program.
18608 Now it also works for shell variables.
18610 2002-02-07 Akim Demaille <akim@epita.fr>

18622 2002-02-06 Akim Demaille <akim@epita.fr>
18624 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18625 sure not to introduce newlines in at_groups.
18626 * lib/autotest/Makefile.am (autotest.m4f): Typo.
18628 2002-02-06 Akim Demaille <akim@epita.fr>
18630 * tests/torture.at (Configuring subdirectories): Skip if aclocal
18633 2002-02-05 Paul Eggert <eggert@twinsun.com>
18635 * doc/autoconf.texi (Specific Compiler Characteristics):
18636 Describe HP-UX cc bug workaround more accurately.
18637 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
18639 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
18640 cross-compilers, too. This undoes some of the most recent change
18643 2002-02-05 Akim Demaille <akim@epita.fr>
18645 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
18646 to make sure they are up to date when `check' is run.
18648 2002-02-05 Akim Demaille <akim@epita.fr>
18650 * doc/autoconf.texi (Making testsuite Scripts): Document
18653 2002-02-05 Akim Demaille <akim@epita.fr>
18655 * lib/freeze.mk: New.
18657 2002-02-05 Akim Demaille <akim@epita.fr>
18659 Implement `autom4te --freeze'.
18661 * bin/autom4te.in (&freeze): New.
18662 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
18663 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
18665 2002-02-05 Akim Demaille <akim@epita.fr>
18667 * bin/autom4te.in (&parse_args): Implement `frozen files are
18668 optional are the sum of the previous files on the command line'.
18669 Also, pass `--reload-state=' on them, so...
18670 (handle_m4): don't.
18671 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18672 (M4sh): Rely on M4sugar.
18673 (Autotest, M4sh, M4sugar): Use frozen files.
18675 2002-01-31 Akim Demaille <akim@epita.fr>
18677 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
18678 * doc/autoconf.texi (Initializing configure): Adjust.
18680 2002-01-30 Akim Demaille <akim@epita.fr>
18682 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
18683 alphanumeric to `-' instead of `_'.
18685 2002-01-30 Akim Demaille <akim@epita.fr>
18687 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
18688 for plain code, the other for cross-compilation code. The latter
18689 is now run with GCC only.

18703 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18705 2002-01-28 Akim Demaille <akim@epita.fr>
18707 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18710 2002-01-28 Akim Demaille <akim@epita.fr>
18712 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18713 AUTOTEST_PATH *after* it was set.
18714 Don't put `.' in the PATH: the user should be precise and `./' if
18715 needed. In addition, given that the test suite does some `cd', if
18716 `.' is in the path, the `tested programs' sections will report
18717 programs found in the test suite's directory, while during the
18718 tests (performed in their own directory), these programs are no
18719 longer visible. In other words, the results is confusing and
18721 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18732 2002-01-24 Akim Demaille <akim@epita.fr>
18734 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
18735 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
18736 Bourne. Use /bin/sh.
18737 From Andreas Buening.
18739 2002-01-24 Akim Demaille <akim@epita.fr>
18741 * config/config.guess, config/config.sub, config/texinfo.tex:
18742 Update from masters.
18744 2002-01-24 Akim Demaille <akim@epita.fr>

18755 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
18756 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
18757 Reported by Geir Ove Myhr.
18759 2002-01-21 Akim Demaille <akim@epita.fr>

18763 2002-01-21 Akim Demaille <akim@epita.fr>
18765 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
18766 message on invalid options.
18767 * bin/autom4te.in (parse_args): Don't use
18768 Autoconf::General::getopt with non valid options.
18770 2002-01-17 Jim Meyering <meyering@lucent.com>
18772 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
18773 $ac_cv_exeext so we don't use an old, invalid, cached value.
18775 2002-01-11 Akim Demaille <akim@epita.fr>
18777 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

18784 2002-01-06 Akim Demaille <akim@epita.fr>
18786 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18787 package.m4, since is really depends upon configure.ac, not
18789 * doc/autoconf.texi (testsuite Scripts): Adjust.
18790 * tests/Makefile.am (package.m4): New.
18791 EXTRA_DIST it since its a source.
18793 2002-01-06 Akim Demaille <akim@epita.fr>
18795 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18796 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18797 and PACKAGE_BUGREPORT from here...
18798 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18800 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18801 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18802 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18803 * tests/tools.at (autoheader): Adjust.
18804 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18806 2002-01-06 Akim Demaille <akim@epita.fr>

18823 * doc/autoconf.texi (New Macros): Tweak wording.
18825 2001-12-14 Akim Demaille <akim@epita.fr>
18827 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18828 trailing files, don't apply `-rf' to files which might not be
18829 created by configure (core, core.*, and *.core), but just `rm -f'.
18830 Suggested by Jonathan Kamens.
18832 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18834 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18836 2001-12-14 Akim Demaille <akim@epita.fr>
18838 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18840 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18842 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18843 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18844 abs_srcdir, top_srcpath to abs_top_srcdir.
18845 (_AC_OUTPUT_FILES): Adjust.
18846 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

18856 2001-12-12 Kevin Ryde <user42@zip.com.au>
18858 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18859 forbidden file descriptors table.
18861 2001-11-26 Akim Demaille <akim@epita.fr>
18863 * bin/autoscan.in (%c_keywords): Build it at top level.

18868 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18869 Remove $filepath, useless.
18870 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18871 variables, they are really part of the tokens.
18872 Split the input line on spaces and then look for tokens.
18873 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18874 because of `lex$U.$(OBJEXT)'.
18875 (&scan_files): Use "@list" instead of join.
18876 * doc/Makefile.am (CLEANFILES): Add *.fns.
18878 2001-11-26 Akim Demaille <akim@epita.fr>

18881 Remove, replaced by...
18882 * tests/wrappl.in: Be common for all the Perl executables.
18883 In particular autoscan and autoheader want -I.
18884 * configure.ac: Adjust.
18885 * lib/autoscan/headers: errno.h is portable.
18887 2001-11-26 Akim Demaille <akim@epita.fr>
18889 * bin/autoscan.in (used): New.
18892 2001-11-26 Akim Demaille <akim@epita.fr>

18904 comment made the whole line be ignored.

18908 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18909 (testsuite Scripts): Be one of its subsection.
18910 (Autotest Logs): New.
18912 2001-11-26 Akim Demaille <akim@epita.fr>
18914 Test groups are now run two directories deeper.
18916 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18917 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18919 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18920 top_srcdir, builddir and top_builddir.
18921 Use `at_*dir' relatively to the directory containing the
18922 suite, use `*dir' when relatively to the current group dir.

18928 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18931 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18933 * doc/autoconf.texi (Using System Type): Add an example of `case
18934 $host' usage so people quit using `case $target' everywhere.
18936 2001-11-22 Akim Demaille <akim@epita.fr>
18938 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18939 spotted by Jim Meyering.
18941 2001-11-16 Paul Eggert <eggert@twinsun.com>
18943 This patch implements a `long double' suggestion by Oliver Kiddle.
18945 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18946 static, to catch errors if the value isn't known at compile-time
18947 and the compiler supports dynamic arrays. Change its name from
18948 `_array_' to `test_array' to avoid potential name clashes.
18949 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18950 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18951 better than double. Catch a bug in GCC 2.95.2 x86.
18952 * doc/autoconf.texi (C Compiler): Document the above.
18955 2001-11-13 Akim Demaille <akim@epita.fr>
18957 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18959 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18961 2001-11-13 Akim Demaille <akim@epita.fr>
18963 * lib/autotest/general.m4 (AT_INIT): After having run the test
18964 group, go back to the initial directory, not to at_suite_dir.
18966 2001-11-13 Akim Demaille <akim@epita.fr>
18968 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18969 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18970 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18972 (AT_CHECK_CONFIGURE): Use absolute paths.
18973 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18974 The problem is still the old one: there is no means in M4 (that I
18975 know about) to create a defining macro, because there is no means
18976 to create `$1' etc., therefore, the defining macro ``swallows''
18977 all the arguments meant to the defined macro.
18979 2001-11-13 Akim Demaille <akim@epita.fr>
18981 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18982 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18984 * tests/aclocal.m4: Remove, as it is no longer used.
18986 2001-11-13 Akim Demaille <akim@epita.fr>
18988 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18989 variable names when referring to a single test group, or to
18990 `suite' when referring to the whole test suite.
18991 `at_last_test' is removed: m4 compute at_format itself.
18992 (at_stdout, at_stder1, at_stderr): New variables.
18993 (AT_CHECK): Use them.
18995 2001-11-13 Akim Demaille <akim@epita.fr>
18997 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18999 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19000 Do it as soon as a test fails, don't wait till the end of the test
19002 Don't remove $as_me.[0-9]*, since these files no longer exist.
19004 2001-11-13 Akim Demaille <akim@epita.fr>
19006 * tests/tools.at: Use absolute paths, since we are no longer run
19009 2001-11-13 Akim Demaille <akim@epita.fr>
19011 Now that tests are running in their own private dir, there is no
19012 need to list the files to remove at the end of tests groups.
19014 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19015 (AT_data_files, at_data_files): Remove.
19016 (AT_CLEANUP, AT_DATA): Simplify.
19018 Remove the group dir if !debug && !failed.
19019 * tests/atspecific.m4: Adjust.
19021 2001-11-13 Akim Demaille <akim@epita.fr>
19023 Start a new layout for Autotest: `testsuite' creates
19024 `testsuite.dir' in which the at-check-line etc. files are to be
19025 found, and `testsuite.dir/003' where the test group 3 is run.
19027 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19028 at_check_line_file, at_format, at_test_normalized, at_group_dir
19030 Create the directories.
19031 Use absolute paths for at- files.
19032 (AT_CHECK): Adjust.
19034 2001-11-11 Michael Matz <matz@kde.org>
19036 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19038 (m4_car): Properly quote arguments.
19040 2001-11-13 Akim Demaille <akim@epita.fr>
19042 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19043 with stricter rules on LIBOBJS.
19045 2001-11-12 Paul Eggert <eggert@twinsun.com>
19047 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19048 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19051 2001-11-12 Akim Demaille <akim@epita.fr>
19053 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.

19060 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19061 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19062 specify to what the macro should be defined (typically to 1).
19064 2001-11-12 Akim Demaille <akim@epita.fr>
19066 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19069 2001-11-12 Akim Demaille <akim@epita.fr>
19071 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19072 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19073 definition used by Automake where LEX is +/- "${missing} lex" and
19074 `missing' itself contains variables.
19076 2001-11-12 Akim Demaille <akim@epita.fr>
19078 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19079 Now that M4sh pushes BODY, the comments were output at the end of
19082 2001-11-08 Akim Demaille <akim@epita.fr>
19084 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19085 that we can trace macros from aclocal.m4.
19086 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19087 obsoleted, and redirect to the former anyway.
19088 Reported by Ralf Corsepius.
19090 2001-11-08 Akim Demaille <akim@epita.fr>
19092 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19093 processed only if present.
19094 * tests/torture.at (Configuring subdirectories): Use autoreconf
19095 instead of successive calls to autoconf.
19096 Add a nonexistent subdirectory to exercise the patch above.
19097 Reported by Ralf Corsepius.
19099 2001-11-08 Kevin Ryde <user42@zip.com.au>
19101 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

19120 * tests/Makefile.am (testsuite): Rename this target as...
19121 ($(TESTSUITE)): this.
19124 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19126 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19127 the --prefix option, also remove it's argument.
19129 2001-11-05 Akim Demaille <akim@epita.fr>
19131 * doc/autoconf.texi (testsuite Invocation): Update.
19132 (Writing testsuite.at): Update.

19143 Use and export them.
19144 (&find_configure_ac): Optionally take a directory where to look at.
19145 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19147 Default @ARGV to `.', not find_configure_ac.
19148 (&autoreconf): Argument is a directory.
19149 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19150 * doc/autoconf.texi (autoreconf Invocation): Update.
19152 2001-11-03 Akim Demaille <akim@epita.fr>
19154 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19155 (@export_forward_subs): New.
19156 Add basename, dirname, and fileparse.
19158 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19159 Don't look for aclocal flags if we already know aclocal is not
19161 Move aclocal.m4t only if it exists.
19162 Reported by Ezra Peisach.
19164 2001-11-03 Akim Demaille <akim@epita.fr>
19166 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19167 passed on command line, defaulting to ./configure.ac if present.
19168 (&maybe_autoreconf, File::Find): Remove, unused.
19169 (&autoreconf): If autoconf is not used, don't try to trace.
19171 2001-11-02 Akim Demaille <akim@epita.fr>
19173 * configure.ac: Bump to 2.52g.
19175 2001-11-02 Akim Demaille <akim@epita.fr>
19179 2001-11-02 Akim Demaille <akim@epita.fr>
19181 * config/config.guess, config/config.sub, doc/standards.texi:
19182 * config/lispdir.m4: Update from masters.
19183 * configure.ac: Bump to 2.52f.
19185 2001-11-02 Akim Demaille <akim@epita.fr>
19187 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19188 Don't run aclocal when aclocal.m4 is not from aclocal.
19190 Don't run libtoolize and gettextize if --install is not given.
19192 2001-11-01 Paul Eggert <eggert@twinsun.com>
19194 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19195 be invoked before _AS_LINENO_PREPARE.
19196 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19197 than character ranges.
19199 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19200 invoking AS_BASENAME. Set the locale variables to 'C' if
19201 possible, as POSIX requires this to get the traditional
19203 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19205 2001-10-31 Paul Eggert <eggert@twinsun.com>
19207 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19208 with {}, as that triggers a bug in Bash 2.05.
19210 (_AS_LINENO_PREPARE): Use Sed rather than
19211 Awk. Fix the sed prepass to work even if there are multiple
19212 instances of $LINENO on the same line. Do not substitute for
19213 other variables like $LINENOT. Do not check file dates; such a
19214 check is unreliable on sufficiently fast machines, and removing
19215 the check makes the code simpler and more reliable. Check for
19216 output and chmod failures.
19218 * doc/autoconf.texi (Special Shell Variables): Document
19221 2001-10-31 Akim Demaille <akim@epita.fr>
19223 * tests/Makefile.am (atconfig): Remove this target, Automake
19226 2001-10-31 Akim Demaille <akim@epita.fr>
19228 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19229 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19230 provided, while it is optional.
19231 * configure.ac: Adjust.
19233 2001-10-26 Paul Eggert <eggert@twinsun.com>
19235 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19236 lib/Autom4te/Struct.pm:
19237 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19240 * doc/autoconf.texi (Special Shell Variables): Document some
19241 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19243 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19244 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19245 eval $LINENO is not portable in practice.
19247 2001-10-24 Akim Demaille <akim@epita.fr>
19249 * lib/Autom4te/General.pm (backname): New.
19251 2001-10-24 Akim Demaille <akim@epita.fr>

19261 2001-10-22 Paul Eggert <eggert@twinsun.com>
19263 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19264 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19265 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19266 POSIX decided to standardize on the int flavor of strerror_r.
19267 Always do char* test, as there's no reason not to.
19268 Assign to a char* var, to catch strerror_r that returns int*.
19270 * doc/autoconf.texi (Particular Functions):
19271 Document the above changes. Also, document the fact that
19272 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19274 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19276 2001-10-20 Akim Demaille <akim@epita.fr>
19278 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

19281 2001-10-20 Akim Demaille <akim@epita.fr>
19283 * lib/Autom4te/General.pm (&update_file): If destination is
19284 unchanged, remove the source.
19285 (&up_to_date_p): Don't be verbose, be debug.
19286 * bin/autoreconf.in: No longer support --m4dir.
19287 (&autoreconf): Display the full path of the configure.ac we are
19289 Trace it only once.
19290 Be sure to honor --force with gettextize.
19291 Always run aclocal.
19292 * doc/autoconf.texi: Adjust.
19294 2001-10-20 Akim Demaille <akim@epita.fr>
19296 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19298 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19299 `intl' is already present, as it refuses unless --force.
19300 (&parse_args): Use -I, --include instead of the old Autoconf
19302 ($localdir, $autoconf_dir): Remove.
19304 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19306 2001-10-19 Jens Petersen <petersen@redhat.com>
19308 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19324 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
19326 * bin/autoreconf.in (autoreconf): Display the path to the
19327 configure.ac being studied.
19329 2001-10-18 Paul Eggert <eggert@twinsun.com>
19331 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19332 long, to work around a bug in the HP C compiler version HP92453-01
19335 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19336 (AS_BASENAME_EXPR): New macro.
19337 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19338 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19339 and fall back on 'sed' only if the other two fail. This makes
19340 AS_BASENAME act more like AS_DIRNAME.
19341 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19342 contains white space.
19343 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19344 Use AS_DIRNAME, since I think it's now DOS-friendly.
19345 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
19346 Allow "dirname //FOO" to return either / or //, as POSIX allows
19349 2001-10-10 Akim Demaille <akim@epita.fr>
19351 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

19357 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

19472 include handle the m4_pattern_*, no longer push the

19483 CONFIG_SHELL defaults to a shell that supports LINENO if available.
19485 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
19486 shell does not support LINENO, and if CONFIG_SHELL is unset or
19487 empty, and if we can find a shell that does support LINENO,
19488 then set CONFIG_SHELL to that shell and then re-execute
19489 ourselves with CONFIG_SHELL.
19491 2001-10-05 Paul Eggert <eggert@twinsun.com>
19493 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19494 doesn't exist. Remove *.tmp, as a .tmp file is created during the

19565 Don't use nested parenthesization. This patch was originally
19566 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,

19576 and invoke a new argument $4 if either is discovered.
19577 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
19578 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

19796 * lib/autotest/general.m4: Englishoes.
19797 From Tim Van Holder and Alexey Mahotkin.

19801 * doc/autoconf.texi (Common Shell Constructs): New node,
19802 documenting AS_DIRNAME.
19803 (Limitations of Usual Tools): Refer to it when discussing dirname.
19804 Also, update discussion of POSIX standard to reflect latest draft.
19806 * lib/autoconf/c.m4:
19807 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19809 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19810 Do not pass a first argument with leading '-'
19811 to expr, by parenthesizing initial integers that might be negative.
19813 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19814 now merely checks whether it is an error to pass an argument
19817 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19818 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19819 whether it is a (compile-time) error to pass an argument to
19820 getpgrp. This simpler test supports the revised documentation,
19821 and is all that AC_FUNC_GETPGRP's users really need.
19823 2001-09-18 Akim Demaille <akim@epita.fr>
19825 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19837 Add test for AS_BASENAME.
19838 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19839 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19840 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19841 * tests/base.at: Fixed the expected responses. The old ones were
19843 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19844 the documentation claims it should (and how it behaved in 2.13).
19846 2001-09-18 Akim Demaille <akim@epita.fr>
19848 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19849 the AC_CONFIG_COMMANDS invocation.
19850 This also solves the name clash problems.
19851 Don't set the package's ID.
19852 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19853 No longer to be shipped.
19854 (version.in): Remove.

19856 * lib/autoconf/status.m4: Adjust.
19857 Use `m4_PACKAGE_STRING'.
19858 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19859 the only optional argument is the name of the test suite.
19860 Expect `package.m4' to define the package signature.
19861 * lib/autom4te.in (Autotest): Add `package.m4?'.
19862 * tests/Makefile.am (package.m4): New.
19863 * tests/suite.at: ifnames is a victim.
19865 2001-09-18 Akim Demaille <akim@epita.fr>
19867 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19868 AC_LIBSOURCE, AC_CONFIG_FILES.
19869 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19870 program version string doesn't match the package's.
19871 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19876 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19877 Allow expression to return any value that can fit into unsigned long

19882 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19883 Always include <stdio.h> and <stdlib.h>. Evaluate
19884 the expression in an extra function before these includes. Call
19885 fprintf "%d" only after ensuring the argument is of type 'int'.
19886 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19888 2001-09-17 Paul Eggert <eggert@twinsun.com>
19890 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19891 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19892 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19893 when they don't exist.
19895 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19896 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19899 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19900 version with the version used by fileutils 4.1, except use
19901 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19904 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19906 2001-09-13 Akim Demaille <akim@epita.fr>

19946 * lib/autotest/general.m4 (AT_INIT): Create and remove
19947 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19948 test suites can cohabit.
19950 2001-09-13 Akim Demaille <akim@epita.fr>
19952 * tests/mktests.sh: Don't output banners for empty test files.

20051 to avoid GCC warnings.
20054 2001-09-05 Akim Demaille <akim@epita.fr>

20058 2001-09-05 Akim Demaille <akim@epita.fr>
20060 Be ready to handle filenames as stupid as `dnl.at', for if even
20061 the maintainer is dumb enough to do that...
20063 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20064 excellence in M4 quotation: consider `__file__' is active.
20066 And BTW, when invoking m4, pass the --include in the right order:
20069 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

20097 New, extracted from main.
20098 Use IO::File wherever possible.

20100 Therefore be a quoted heredoc.
20101 Don't invoke `_au_disable', since ac was not loaded, but just

20129 2001-08-31 Akim Demaille <akim@epita.fr>
20131 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20132 (testsuite Scripts): There is no such thing as `atconfig.in'.
20133 And actually one diagram is missing: test suite runtime.
20135 2001-08-31 Akim Demaille <akim@epita.fr>
20137 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20140 2001-08-31 Akim Demaille <akim@epita.fr>
20142 * bin/autoupdate.in (@include): `installcheck' revealed the path
20143 to m4sugar was lacking!
20145 2001-08-31 Akim Demaille <akim@epita.fr>

20204 `autoheader: `config.hin' is created'.
20205 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20207 2001-08-31 Akim Demaille <akim@epita.fr>

20215 Map --localdir, --autoconf-dir onto it.
20216 Forward autom4te's options instead of interpreting them.

20218 There is no such envvar since the inception of autom4te.cfg.

20240 * lib/Autom4te/General.pm (&find_peer): Remove.
20241 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

20243 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20244 find the executables for it.
20245 * tests/Makefile.am: Major cleanup. Too lazy to document...
20246 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20248 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20249 indeed related to running the test suite, while passing
20250 --autoconf-dir and others is related to running non installed
20251 Autoconf executables. So don't do that, leave it to...

20253 * tests/autoscan: New.
20254 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20271 Suggested by Paul Eggert.
20273 2001-08-29 Akim Demaille <akim@epita.fr>
20275 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20276 download in a tmp dir.
20278 2001-08-29 Akim Demaille <akim@epita.fr>
20280 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

20450 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
20451 the name of the directory they're in, instead of the filename,

20540 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
20541 * NEWS, README, README-alpha, TODO, tests/README: This package is

20544 2001-08-20 Akim Demaille <akim@epita.fr>

20662 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

20680 * doc/autoconf.texi: Work around Texinfo buglets.
20681 (Transformation Rules): One example is enough, users are expected

20683 (dvar): New macro. Use it.
20685 2001-08-17 Akim Demaille <akim@epita.fr>
20687 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

20740 autom4te.cache (it's a directory, not a file.
20741 * Makefile.am: Ditto (but maintainer-clean-local).
20743 2001-08-15 Akim Demaille <akim@epita.fr>
20745 * bin/autom4te.in (@m4_warning): New.
20746 (&handle_m4): Use it.
20747 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20748 warnings are issued at each run.
20749 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20750 is in the src tree.
20752 2001-08-15 Akim Demaille <akim@epita.fr>

20755 don't waste time running `autoupdate --version' works.
20756 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
20758 2001-08-13 Akim Demaille <akim@epita.fr>

20817 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20819 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20820 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20821 * doc/autoconf.texi (C Compiler Characteristics): Update
20822 documentation for AC_C_BIGENDIAN.
20824 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

20827 magic values from an object file when cross-compiling.
20828 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20830 2001-08-10 Akim Demaille <akim@epita.fr>
20832 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20834 Suggested by Russ Allbery.
20836 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20838 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20839 current $prefix to the sub-configures.
20841 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20843 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20844 extension (needed on BeOS). Reported by Guido van Rossum.
20846 2001-08-09 Akim Demaille <akim@epita.fr>
20848 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20850 2001-08-07 Akim Demaille <akim@epita.fr>
20852 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20854 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20855 No need to remove the files before and after the each test, before
20856 each test and at the end of the suite is enough.
20857 Display only the children `times', not the shell's.
20858 If the test failed or was skipped, at-times is not available.
20860 2001-08-07 Akim Demaille <akim@epita.fr>
20862 Always produce testsuite.log, including when there are no
20863 failures. This helps getting information on skipped tests, and
20864 duration of the tests. Err, implement the latter btw.
20866 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20867 Dump information on the first run of each test.
20868 (AT_CLEANUP): Create `at-times' containing the duration of the
20871 2001-08-07 Akim Demaille <akim@epita.fr>
20873 The use of `dumpstat' revealed that `len' was used although it
20874 should not. m4_text_wrap was using it, but in the Autoconf world
20875 where it is legal. Hence (i) test M4sh in its own world, not
20876 Autoconf's, and (ii), ahem, fix the bug :)
20878 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20879 does not like `' instead of [].
20880 (AT_INIT): Forbid `^_?AT_'.
20881 And don't output such tokens.
20882 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20883 `script.as', and `autom4te.cache'.
20884 Remove `empty' and `macro' which are no longer used.
20885 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20886 * tests/m4sugar.at: Use it.
20887 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20889 2001-08-07 Akim Demaille <akim@epita.fr>
20891 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20893 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20895 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.

20906 2001-08-04 Akim Demaille <akim@epita.fr>
20908 Don't rely on M4sugar outputting the patterns in files, since we
20909 might process the output _without_ running m4, hence without these
20912 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20913 * bin/autom4te.in (@Request::includes): Remove, unused.
20914 (@Request::source): Rename as...
20915 (@Request::input): this.
20916 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20917 (&handle_output): Fetch the patterns from the traces.
20918 `$forbidden' and `$allowed' are constant: use m//o.
20919 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20920 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20922 2001-08-04 Akim Demaille <akim@epita.fr>
20924 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20925 autoconf', i.e., in addition to caching traces, cache the output.
20927 * bin/autom4te.in (Request::cache): Rename as...
20928 (Request::id): this.
20929 ($cache, $icache, $tcache, $ocache): New.
20930 (&handle_m4): Save M4 output in the cache instead of $tmp.
20931 (&handle_output): Adjust.
20932 (&up_to_date_p): Check that the output cache is up to date too.
20933 (top level): Run `&handle_m4' iff force or the cache is invalid.
20934 Run `&handle_output' if the output cache is more recent.
