4952 * doc/autoconf.texi (Particular Programs): Do not mention the
4953 Autoconf version in which the AC_PROG_INSTALL change was done.
4954 Suggested by Paul Eggert.
4956 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4958 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4959 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4960 mode, we change to the source directory, also set $ac_pwd so we
4961 do not go back to the build tree for the next config subdir.
4962 * tests/torture.at (Deep Package): Extend test to contain two
4963 config subdirs on the top level.
4965 Fix parallel `maintainer-check'.
4966 * Makefile.am (maintainer-check-tests): Depend on `all'.
4967 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
4968 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
4970 (maintainer-check): Serialize the testsuite runs.
4972 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
4973 in feature string for --enable/--with. Convert to underscore
4976 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
4977 `install -c file1 file2 dir' works.
4978 * doc/autoconf.texi (Particular Programs): Document this.
4981 2008-01-21 Eric Blake <ebb9@byu.net>
4983 Improve documentation about default include directives.
4984 * doc/autoconf.texi (Generic Headers, Generic Declarations)
4985 (Generic Structures, Generic Types)
4986 (Generic Compiler Characteristics): Add links to
4987 AC_INCLUDES_DEFAULT.
4988 Reported by Reuben Thomas.
4990 2008-01-15 Eric Blake <ebb9@byu.net>
4992 * lib/m4sugar/m4sugar.m4 (m4_qlen): Use fewer macros.
4994 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4996 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
4997 check_SCRIPTS. Building the wrappers for `all' allows help2man
4998 to use them for the manpages.
4999 Report by Benoit Sigoure.
5001 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
5003 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5005 Fix some write failure cases in Autotest.
5006 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
5007 upon write failures for --help, --version, --list.
5008 Guard against write failures for intermediate created scripts.
5009 <at_func_create_debugging_script>: Do not make the debugging
5010 script executable if it is not complete.
5012 2007-12-12 Eric Blake <ebb9@byu.net>
5014 Fix thinko in earlier patch - m4_join isn't defined yet.
5015 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5016 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5017 (m4_require): Use m4_do, not m4_join.
5019 Fix some whitespace tests on cygwin.
5020 * tests/tools.at (autom4te and whitespace in file names): Restore
5021 font-lock. Create $TMPDIR before it might be used.
5023 Fix spurious testsuite failure with M4 1.4.11.
5024 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5026 Optimize AC_REQUIRE.
5027 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5028 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5029 (m4_require): Avoid extra macro calls.
5031 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5033 * tests/torture.at (srcdir): Fix quoting.
5035 Do not pass top_srcdir to configure scripts in testsuite.
5036 * tests/autotest.at (srcdir propagation): Copy install-sh to
5038 (my only test): Drop setting of `top_srcdir'.
5039 * tests/base.at (Input/Output): Likewise.
5040 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5041 config.guess, and config.sub to test source tree.
5042 Drop AC_CONFIG_AUX_DIR setting.
5043 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5044 * tests/torture.at (Substitute a 2000-byte string): Drop
5045 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5046 (Substitute a newline, datarootdir workaround): Likewise.
5047 (Define a newline): Adjust for linenumber changes in configure.ac.
5048 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5050 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5051 if `pwd` contains whitespace.
5053 Quote $abs_top_srcdir in tests.
5054 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
5055 * tests/tools.at (Syntax of the shell scripts): Likewise.
5057 * tests/m4sh.at (LINENO): Quote $0.
5059 Fix testsuite program wrapper for whitespace in `pwd`.
5060 The problem here is that the usual mantra is that command
5061 variables can contain arguments, thus we cannot just escape
5062 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5063 $top_builddir/tests directory early in $PATH, so that the
5064 wrappers are found by their plain name.
5065 * tests/wrapper.as: Put $testdir early in $PATH.
5066 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5068 Proper config.status --file/--header and $srcdir escaping.
5069 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
5070 characters in $ac_file_inputs.
5071 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
5073 * tests/torture.at (datarootdir workaround): Adjust.
5074 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5076 Fix Autotest for whitespace in `pwd`.
5077 * lib/autotest/general.m4 (AT_INIT)
5078 <at_func_create_debugging_script, Driver Loop>:
5079 Quote $at_group_dir.
5080 * tests/autotest.at (whitespace in absolute testdir): New test.
5082 * lib/autom4te.in: Quote @datadir@.
5084 Proper file name escaping in Autoconf programs and Perl modules.
5085 This includes escaping of characters special to the shell
5086 as well as special to Perl, e.g., leading `<' or `>'.
5087 For example, when $file starts with `>', `open ">$file"'
5088 wrongly tries to append to a different file.
5089 * bin/autoconf.as: Fix quoting for autom4te options.
5090 * lib/Autom4te/General.pm (shell_quote): New function, taken
5091 from coreutils, written by Jim Meyering.
5093 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
5095 * bin/autoreconf.in (parse_args): Likewise.
5096 * bin/autoscan.in (main): Likewise.
5097 * bin/autoupdate.in (main): Likewise.
5098 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
5099 * bin/ifnames.in: Likewise, XFile usage fixes.
5100 * tests/tools.at (autom4te and whitespace in file names): Extend
5101 test. Test twice, with special characters allowed on w32, and the
5102 rest. Test leading and trailing whitespace, for `open_quote'.
5103 (autotools and whitespace in file names): New, analogous test.
5104 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5105 by Russ Allbery and Eric Blake.
5108 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5109 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5110 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5111 (update_file, contents): Use it.
5113 * Makefile.am (autom4te-update): Rewrite for git.
5115 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5117 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5119 Fix copyright years.
5120 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5121 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5123 2007-12-04 Eric Blake <ebb9@byu.net>
5125 Manually resync with gnulib, since 'make cvs-update' no longer works.
5126 * build-aux/config.guess: New upstream version.
5127 * build-aux/config.sub: Likewise.
5129 When using older automake, don't downgrade build-aux/texinfo.tex.
5130 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
5131 * doc/Makefile.am (TEXINFO_TEX): Add.
5133 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5135 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5136 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5137 #undef as this runs afoul of our new way of creating config.h.
5138 Problem reported by Jim Meyering in
5139 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
5141 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5143 Fix autom4te for unusual characters in input file names.
5144 * bin/autom4te.in (files_to_options): Quote active characters
5146 * tests/tools.at (autom4te and white space in file names):
5149 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5150 Document that Tru64 awk always splits $0.
5152 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5154 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5155 `#AT_STOP_...' line at the end of each test.
5157 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5159 * lib/autotest/general.m4 (AT_INIT): For awk line number
5160 extraction script, ensure `$at_group' has a defined value
5161 even for the empty set, and properly quote its usage inside
5164 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5166 * doc/autoconf.texi (Shell Functions): New chapter. Document
5167 IRIX sh $0 issue in functions, move content from ...
5168 (Portable Shell): ... here.
5169 (Shell Script Compiler): Note that shell functions are not
5170 totally unportable any more.
5172 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5173 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5175 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5176 extracting the line numbers of the last needed test.
5178 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5180 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5183 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5185 Fix IRIX testsuite debugging failures: $0 in functions.
5186 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5187 Do not use $0 inside a function, as IRIX sh will set that to the
5188 function name rather than the script invocation name.
5190 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5191 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5193 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5194 to extract test scripts.
5195 (AT_INIT): Extract and cache test script line numbers.
5197 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5199 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5200 subsequent fixups; the awk -> here-document conversion trashes
5201 performance too much with AIX sh.
5203 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5205 * tests/local.at: Do not test m4, perl with AT_TESTED.
5207 Diagnose and guard against write errors dealing with config.status.
5208 The general idea is this: all write failures from `configure'
5209 writing `config.status' are indicated by $ac_write_error, which
5210 is only checked at the end. This is safe because config.status
5211 code is not executed before the file is complete. Other write
5212 failures, be they inside config.status, or in sub shell/awk
5213 scripts spawned from configure or config.status, typically need
5214 earlier checking, as their results are used right afterwards.
5215 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5216 before writing config.status, check afterwards.
5217 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5218 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5219 Set `ac_write_error' for write failures to config.status. Barf
5220 upon write failures to temporary files.
5221 Adjust note about closing and reopening the here-document.
5222 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5223 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5224 reopening the here-document.
5225 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5226 Ensure `ac_write_error' does not escape into config.status.
5227 Also, add a couple of code paths not yet exercised in the test
5228 suite: a config file with input from stdin, and a config header
5230 Suggestion for catching write errors by Bruno Haible.
5232 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5234 Avoid error with Tru64 awk and testsuite lines with many words.
5235 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5236 reads the testsuite, set the field separator to an unusual value,
5237 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5238 even splits the input if $i, i>0, was never accessed in the script.
5240 Revert 2007-10-17 change.
5241 * TODO: Multiline args in config files and headers mean something
5242 different and are not fixed, see
5243 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

5248 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5250 AC_*_TOOL does not canonicalize the prefix
5251 * doc/autoconf.texi (Generic Programs): Do not say that
5252 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5254 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5256 Diagnose write errors in config.status instantiations.
5257 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5258 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5260 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

5276 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
5277 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5279 * lib/autotest/general.m4 (at_func_test): Remove.
5280 (AT_INIT): Pre-extract test groups into separate files.
5281 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5282 Remove at-test-source files together with the $at_group_dir.
5283 * tests/autotest.at (Long test source lines): New test.
5285 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5287 Shell functions and variables may share a namespace.

5293 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
5296 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5298 * lib/autoconf/status.m4: Fix a couple of comment typos.
5300 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
5302 2007-11-13 Jim Meyering <meyering@redhat.com>
5304 Clean up the rule to create "expr".
5305 * tests/Makefile.am (expr): Don't redirect directly to target.
5306 Redirect just once, not for each echo statement.
5307 Use $@, not literal "expr".
5309 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
5311 Don't worry about preprocessor when testing long long.
5312 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5313 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5314 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5315 These no longer check for preprocessor flaws.
5316 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5317 Do not check for preprocessor flaws.
5319 2007-11-13 Jim Meyering <meyering@redhat.com>
5321 Adapt dependencies, now that a version change doesn't modify configure.ac
5322 * GNUmakefile: Remove "make clean" kludge.
5323 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
5325 Don't redirect directly to target.
5326 Use $@, not literal "version.m4".
5328 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5331 ":;{" shorthand as in previous patch.
5333 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>

5336 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
5338 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
5339 Use ":;{" shorthand.
5340 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
5342 2007-11-12 Jim Meyering <meyering@redhat.com>
5344 Add more non-srcdir build support.
5345 * GNUmakefile (dummy): Split a long line.
5346 Add -v option to autoreconf invocation.
5348 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5349 * GNUmakefile (dummy): Remove INSTALL.
5351 Remove racy commands to build scripts in bin/ and tests/.
5352 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5353 are guaranteed to be built, remove the rules that tried to build
5354 them. Before, with a parallel build, these rules could lead to
5355 two processes writing tests/wrapper.in concurrently.
5357 Build in man/ only *after* building in bin/ and tests/.
5358 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5359 in both bin/ and tests/.
5361 Accommodate non-srcdir build-from-checkout.
5362 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5363 Use git's --git-dir=$srcdir/.git option.
5364 Add quotes, in case tarball_version_file contains shell meta-characters.
5365 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5366 * configure.ac: Pass "." to git-version-gen.
5368 Avoid spurious test failures due to version skew.
5369 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

5396 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5398 Ignore configure --help* errors due to LINENO-impaired shells.
5399 * tests/torture.at (Configuring subdirectories, Deep Package):
5400 In the --help* tests in read-only trees, make `.' temporarily
5401 writable again for the `stderr' file, and ignore errors due to
5402 the attempt to write configure.lineno.
5403 Report by Patrick Welche.
5405 2007-11-10 Jim Meyering <meyering@redhat.com>
5407 Generate package.m4 in build-dir, not srcdir.
5408 * tests/Makefile.am (package.m4): Adjust target.
5409 Don't redirect directly to $@.
5410 (CLEANFILES): Add package.m4.
5411 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5413 When running $(AUTOTEST), search "." before searching $(srcdir).
5415 Avoid a race condition that would make parallel "distclean" fail.
5416 * tests/Makefile.am (distclean-generic): Replace the default,
5417 automake-provided rule with an identical one, but with an additional
5418 dependency on distclean-local. Simply adding the dependency would
5419 cause automake not to emit the rule at all.
5420 * BUGS: Building with -jN works, now.
5422 Distribute git-version-gen.
5423 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5424 since GNUmakefile is distributed, and requires it for dist* rules.
5426 Remove two more generated files from version control.
5427 * INSTALL: Remove generated file.
5428 * lib/autoscan/autoscan.list: Remove generated file.
5430 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5432 * GNUmakefile (PATH): Remove stray apostrophes; they become
5433 part of PATH, which isn't wanted here.
5435 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5454 when using Automake, to write a rule to produce atlocal, since it's
5455 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5456 distributed, not atconfig.in.

5557 Make inter-release --version output more useful.
5559 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5560 which indicates that it is built using the 19th change set
5561 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5562 is a prefix of the commit SHA1.
5563 * build-aux/git-version-gen: New file.

5568 * .gitignore: Add .version here, too. Just in case.
5569 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5570 not configure.ac, now that the version number changes automatically.
5572 Ensure that $(VERSION) is up to date for dist-related targets.
5573 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5574 git-version-gen doesn't match $(VERSION), but only for dist targets.

5645 this resolution. Fixes test failure on FreeBSD.
5647 Fix config header generation with AIX awk.
5648 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
5649 script, use helper array D_is_set, as `" 0"' does not evaluate

6871 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6872 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6873 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6874 works but the latter doesn't, then it's a valid type.
6875 This lets people use function types and so forth.
6876 For C++ there doesn't seem to be a simple solution, so leave it alone.
6877 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6878 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

6940 2007-03-09 Stepan Kasal <kasal@ucw.cz>
6942 * doc/autoconf.texi (Specifying Names): `--host' does not
6943 change the build type.
6945 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

6967 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
6968 Reindent for sanity's sake.
6970 2007-02-24 Eric Blake <ebb9@byu.net>
6972 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

6981 status of rm so we know when it failed.
6982 If cleaning of test dir failed before running the test, warn.
6983 Output the line separator in verbose mode before the warning
6984 to make clear the warning belongs to the following test.

7050 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7051 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7052 substitution will still be done by the special code.

7068 Report against Automake by Patrick Welche.
7070 2007-01-15 Stepan Kasal <kasal@ucw.cz>
7072 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
7074 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7076 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7077 early on the reader side, drop stderr of the input to avoid
7078 `broken pipe' error output; this may happen even with shell
7079 builtin `echo' of some bash versions. Reports by Ian Macdonald
7080 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7082 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7084 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

7095 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7096 * doc/autoconf.texi (Signed Overflow Examples): Give more
7097 discussion about the allow_superuser_privileges example,
7098 and change it a bit to make things clearer.
7099 (Optimization and Wraparound): Clarify whether the compiler
7100 will generate an infinite loop for the example derived from
7101 Autoconf's mktime test.
7102 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7103 Also, clarify unsigned multiplication overflow.
7105 2007-01-04 Eric Blake <ebb9@byu.net>
7107 * bin/Makefile.am (RELEASE_YEAR): New macro.
7108 (edit): Use it to supply correct copyright year to scripts.
7109 * bin/autoconf.as (version): Use it.
7110 * bin/autoheader.in ($version): Likewise.
7111 * bin/autom4te.in ($version): Likewise.
7112 * bin/autoreconf.in ($version): Likewise.
7113 * bin/autoscan.in ($version): Likewise.

7115 * bin/ifnames.in ($version): Likewise.
7117 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7119 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7120 feedback. The most important changes document what happens when
7121 you convert an out-of-range value to a signed integer type, and
7122 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7125 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7126 rewrite, taking notions from the recent discussion on the gcc and
7127 autoconf mailing lists; please see
7128 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7129 and follow the many links.
7130 (Integer Overflow Basics, Signed Overflow Examples):
7131 (Optimization and Wraparound, Signed Overflow Advice):
7132 (Signed Integer Division): New sections.
7134 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7136 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7137 preprocessor macro arguments in traced name.
7138 * doc/autoconf.texi (Defining symbols): Document longstanding
7139 support for AC_DEFINE-ing macros with arguments, and document
7140 behavior when the same variable has multiple AC_DEFINEs.
7141 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7142 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7143 macros directly, giving much shorter and simpler code.
7145 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7147 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7148 space before "$ac_configure_args" to prevent a 'config.status
7149 --recheck' failure if ac_configure_args doesn't contain a leading
7150 space. This works around a problem with the XEmacs configure.ac,
7151 which uses the (undocumented) ac_configure_args variable
7152 inconsistently with Autoconf.
7154 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7156 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7157 Include <limits.h>, and use its INT_MAX to rewrite the
7158 j loop so that it does not overflow 'int'. Problem reported by
7160 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7161 Play it safe by shifting left by 1 rather than multiplying by 2,
7162 as GCC is less likely to optimize this away when the value
7163 is signed (when it assumes overflow leads to undefined behavior).
7164 Also, don't assume time_t uses two's complement.
7166 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7168 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7169 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7170 dumps core on it. Report by Tim Rice.
7172 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7174 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7175 --disable-option-checking to --help output even when
7176 AC_PRESERVE_HELP_ORDER is not used.
7177 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7178 --with argument, rather than argument with [-.] replaced by
7180 * NEWS: Fix typo in previous change; the news was in the
7183 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7185 * NEWS: Warnings are now generated by default for unknown
7186 --enable-* and --with-* options.
7187 * doc/autoconf.texi (Option Checking): Renamed from
7188 (Configure Option Checking). Tighten up the wording a bit.
7189 (External Software, Package Options): Cross-reference to Option
7190 Checking, and use this to shorten our section.
7191 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7192 "$x" to test "x$foo" != x.
7193 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7194 Don't warn if $enable_option_checking is "no".
7195 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7196 ac_unrecognized_opts to the empty string.
7197 Don't echo the unrecognized opts, as this might mishandle
7198 backslashes or leading -.
7199 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7200 usage next to the other --disable-FEATURE options in the
7203 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7205 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7206 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7207 Print warning for unrecognized --with and --enable options
7208 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7209 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7210 Disable option checking when subdirs are configured.
7211 (AC_OUTPUT): If warnings are enabled, print warning about
7212 unrecognized --with and --enable options at the end of
7213 the configure output (as well as at the beginning).
7214 * doc/autoconf.texi (Option Checking): New node.
7215 Document new option warning functionality.
7217 2006-12-16 Eric Blake <ebb9@byu.net>
7219 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7220 * NEWS: Start news for current version.
7222 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7224 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7225 Define HAVE_GETMNTENT to 1, not to the empty string.
7226 Problem originally reported by Jochen Friedrich in
7227 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7229 This change prompted by a problem report by Andrey Simonenko in
7230 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7231 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7232 object-like macros only, in the traditional portable character
7234 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7235 Warn about attempts to define things that are not identifiers.
7236 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7237 awful hack that AC_DEFINEd macro names containing parentheses.
7239 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7241 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7242 too drastic, even if Texinfo in theory requires it for info mode.
7244 (config.status Invocation): Renamed back from Recreating a
7246 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7247 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7249 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7251 * NEWS: Version 2.61a.
7253 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7256 * NEWS: Document changes with echo and printf, and the lack
7257 of limits on the total size of multi-line values of substituted
7258 variables, and the AC_FUNC_FSEEKO fix.
7260 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7262 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7263 Writing configure.ac.
7264 (Autoconf Input Layout): Renamed from configure.ac Layout.
7265 (Recreating a Configuration): Renamed from config.status Invocation.
7266 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7267 (acconfig Header): Renamed from acconfig.h.
7268 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7269 (Writing Testsuites): Renamed from Writing testsuite.at.
7270 (Autom4te Cache): Renamed from autom4te.cache.
7272 * BUGS: Remove mention of VPATH problem, since it's now documented
7273 not to be a bug in the Autoconf build procedure itself, but rather
7274 a problem with the proprietary `make' programs.
7276 * doc/autoconf.texi (Build Directories): Add a cross reference
7279 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7280 * doc/standards.texi: Sync from gnulib.
7282 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7283 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7284 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7285 generated automatically.
7287 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7289 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7290 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7291 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7293 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7295 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7296 `CEOF$ac_eof' special marker, the awk script cannot contain a
7297 line matching `^CEOF', so this is not needed any more.
7298 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7299 special marker in the test.
7301 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7303 * tests/tools.at (autom4te preselections): Use `find -newer';
7304 remove one of the sleeps.
7306 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7307 more readable, using ...
7308 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7310 * doc/autoconf.texi (autoheader Invocation): Do not double-
7311 quote the parameter of `AH_BOTTOM' in the example.
7313 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7315 * doc/autoconf.texi (Configuration Headers): Remove the
7316 example with multiple input files.
7317 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7318 multiple input files.
7320 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7322 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7323 creating the awk substitution script, handle one input line at a
7324 time, so that the maximum length of a substituted (multi-line)
7325 value is not limited by the size of the sed pattern space.
7326 The trade-off is a slightly repetitive sed script.
7327 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7328 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7329 * tests/torture.at (Substitute a 2000-byte string): Increase the
7330 test with several long lines, they should not be caught by sed
7333 * tests/tools.at (autom4te preselections): New test, to flag
7334 entries missing from autom4te.cfg.
7335 Report by David Byron <dbyron@hheld.com>.
7337 * tests/torture.at (Substitute a 2000-byte string): Actually use
7338 AC_PROG_AWK, so the last change works as intended.
7339 (Substitute and define special characters): Likewise.
7340 (Substitute a newline): Likewise.
7342 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7343 instead of `awk' consistently.
7344 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7345 * tests/torture.at (Torturing config.status): Test both the
7346 result of AC_PROG_AWK and plain awk.
7347 (Substitute a 2000-byte string): Likewise.
7348 (Substitute and define special characters): Likewise.
7349 (Substitute a newline): Likewise.
7351 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7353 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7354 can be assigned to a function pointer. Problem reported by
7355 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7356 part of a patch by Ralf Wildenhues in that same bug report.
7358 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7360 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7361 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7363 2006-12-01 Eric Blake <ebb9@byu.net>
7365 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7366 cross-compiling from cygwin to mingw.
7367 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7368 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7369 to lib/autoconf/c.m4.
7371 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7373 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7374 string for more reliable failure. Wrap the entire test that
7375 causes the broken Solaris printf to dump core, in a subshell,
7376 so the segmentation fault message is reliably suppressed.
7377 Fix shell expansion errors by using /usr/ucb/echo always;
7378 avoid an error on systems without it by another subshell.
7379 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7380 subshell-$as_echo to `as_echo', for better error message.
7382 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7384 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or

7390 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7391 years and is too hard to maintain now. The last straw was
7392 reported by Jerker Baeck in
7393 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7394 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7395 * doc/autoconf.texi (Particular Functions): Move
7396 AC_FUNC_SETVBUF_REVERSED from here...
7397 (Obsolete Macros): ... to here. Say that it does nothing now.
7398 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7399 Turn into (almost) a no-op.
7401 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7403 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7404 These macros are obsolescent and new applications shouldn't need them.
7405 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
7406 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

7412 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7414 * doc/autoconf.texi (Setting Output Variables): Mention that
7415 @VAR1@VAR2 has unspecified behavior. Problem reported by
7417 * NEWS: Mention this.
7419 * Makefile.am: Put only a single '#' into the copyright notice,
7420 so that it's also present in the output file. Standardize wording
7421 in makefile copyright notices to match GNU coding standards.

7435 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7437 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7438 in the sed script that mangles the awk script: delete up to the
7439 first exclamation mark only.
7440 * tests/torture.at (Substitute and define special characters):
7443 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7445 Rewrite config files generation: avoid quadratic growth in
7446 the number of substituted variables by using awk instead of sed
7447 for the bulk of the substitutions.
7448 * NEWS: Mention this.
7449 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7450 forbidden in the output (and thus input) file.
7451 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7452 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7453 generate just one large awk script for substitutions,
7454 eliminating much of the earlier complexity, while adding some
7455 new complexity. Only expand the substitution templates at
7456 configure time, for smaller configure script size. If
7457 _AC_SUBST_FILES are used, test 'awk' for working getline support
7458 at config.status time. If absent, interpolate through the
7459 shell. The awk script was written with much help
7460 from Paolo Bonzini and Paul Eggert.
7461 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7462 (_AC_SED_FRAG_NUM): Likewise.

7465 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7466 * tests/torture.at (Substitute a 2000-byte string): Also
7467 substitute a line with 1000 words, and a variable with several
7469 (Substitute and define special characters): Test awk special
7470 characters, and put substitution input strings `@foo@' in the
7471 output, to test that no recursion happens; test several other
7472 combinations from Paolo Bonzini.
7474 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7476 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7477 that replaced echo with AS_ECHO where this wasn't necessary.
7478 Problem reportd by Ralf Wildenhues.
7479 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7480 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7481 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7483 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7485 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7487 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7489 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7490 that traditional Awk lacks 3-arg "split". It has it.
7491 Mention that FS must be a single character, and a few other
7492 99-byte limits of traditional Awk.
7493 Mention that if (i in a) doesn't work with traditional Awk.

7499 (Newline-CODE-BS-newline in command):
7500 (Single-quote-BS-newline in command):
7501 (Single-quote-newline-BS-newline in command):
7502 Use printf '%s\n' instead of echo, for portability to hosts
7503 where echo interprets backslashes. This will break on hosts
7504 that lack printf, but for now let's assume all such hosts
7505 are dead (if not, we should get reports of test failures).
7507 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7509 'echo' has some portability problems, when given a first argument
7510 with a leading '-', or when given any argument containing '\'.
7511 Avoid using 'echo' in these cases.

7538 scheme wouldn't work with AS_ECHO.
7539 * lib/autotest/general.m4 (AT_INIT): Likewise.
7540 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7541 Don't use ECHO_T, since ECHO_N is now reliable.
7542 * lib/autotest/general.m4 (AT_INIT): Likewise.
7543 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7544 rather than using a here-document to put the script into a file.
7545 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7547 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7548 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7549 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7550 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7551 * lib/autotest/general.m4 (AT_SETUP): Likewise.

7553 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7554 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
7555 operand, as AS_ECHO requires. Avoid double file name expansion.
7556 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7557 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7558 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7559 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7560 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7561 Double-quote strings that would otherwise contain M4 comments.
7562 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7564 * configure.ac (AC_INIT): Bump to 2.61a.
7567 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7571 * configure.ac (AC_INIT): Bump to 2.61.
7574 * tests/autotest.at (Macro with backslash in a test title):
7575 Comment out for now, as this tests neither fails nor passes
7576 reliably. Problem reported by Ralf Wildenhues.
7578 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7580 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

7691 and Stepan Kasal <kasal@ucw.cz>
7693 Handle special characters in test case titles correctly.
7694 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
7696 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
7697 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
7698 argument. Extend to check titles printed by ./micro-suite and
7699 ./micro-suite -l and the title in micro-suite.log.
7700 (Backquote in a test title,
7701 Single-quote in a test title,
7702 Double-quote in a test title): Don't expect failure anymore.
7703 (Backslash in a test title): Put a non-whitespace character after the
7704 backslash so that Bourne shells might actually see it as an escape
7706 (Brackets in a test title,
7707 Pound in a test title,
7708 Comma in a test title,

7726 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7727 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7728 5363) simply issues a warning when dividing by zero at compile

7763 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
7764 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
7765 reported by Nelson H. F. Beebe for Coreutils 6.4.
7767 * tests/tools.at (autoconf --trace: user macros): Remove test
7768 for tracing multiline macros, since m4 1.4.7a uses a different

7848 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7849 which incorrectly sets the mode of an existing destination
7850 directory. In some cases the unpatched install-sh could do the
7851 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7852 system. We hope this is rare in practice, but it's clearly worth
7853 fixing. Problem reported by Alex Unleashed in
7854 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7855 Also, don't bother to check for -m bugs unless we're using -m;
7856 suggested by Stepan Kasal.

7933 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7934 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7935 Use a better substitute, by inspecting the output of "ls"
7936 rather than just using ":".
7937 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7938 rather than AS_EXECUTABLE_P, since we needn't worry about
7939 non-regular files here.
7941 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7942 due to configuration hassles with this. See Tonya Underwood's report

7954 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
7955 initialization which is not inherited through the environment

7964 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
7966 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7967 comment about ac_cpp_err; it was incorrect, and anyway
7968 ac_cpp_err is being removed below.
7969 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7970 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7971 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7973 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7974 with werror_flag and conftest.err and so forth. This is more
7975 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7976 and anyway the user shouldn't normally want to see this gorp logged.
7977 Problem reported by Ralf Wildenhues.
7978 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7979 empty, not 'no', since the rest of the code uses 'test -z'.

7983 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7984 Use a single call to AC_DO_TOKENS rather than multiple, for
7986 (_AC_LINK_IFELSE): Test that resulting file is executable.
7987 Problem reported by mwoehlke in
7988 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7990 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7991 than creating a file to use with test -x; this is much faster.
7993 2006-10-02 Bruno Haible <bruno@clisp.org>
7995 * lib/autom4te.in (Automake-preselections): Add

8005 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

8007 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8008 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8009 still doesn't let the program compile.
8010 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8013 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8014 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

8023 `error.h', and include it, for a `error_at_line' prototype.
8024 Use a nonempty format string in the link test.
8025 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
8026 for a declaration of wait3.

8032 can apply to constants too, and that it checks for macro defns.
8033 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

8035 values. Problem reported by Ralf Wildenhues.

8250 broken lex libraries like native ia64-hp-hpux11.22; see
8251 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

8379 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
8380 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8381 -Wundef -Werror". Problem reported by David Fang in
8382 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8404 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
8405 problems with arg script text that doesn't end in newline, and
8406 with '-e a...'. Problems reported by Ralf Wildenhues.
8408 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
8410 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

8429 the compiler created a file "b.out" when it didn't create anything
8431 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):

8442 less skeptical about "volatile", after discussion with
8443 Bruno Haible on bug-gnulib.
8444 (Limitations of Usual Tools): Warn about sed stripping
8445 leading white space from text. From Bruno Haible.
8447 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
8449 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
8450 compiler complains about it, even if things works after the
8451 complaint. Problem reported by Peter O'Gorman.

8457 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
8459 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
8460 after -R regardless of host. Patrick Welche reports that this

8472 under AC_C_VOLATILE.
8473 (Volatile Objects): Be a little less skeptical about what
8474 "volatile" means. Derived from thoughts by Ben Pfaff in
8475 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
8477 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8481 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
8483 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8484 more globally, since the 2006-06-30 patch didn't suffice. Problem
8485 reported by Keith Marshall. Also, don't bother with builddir2,
8486 since it shouldn't be needed any more.
8488 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

8491 Document AC_COMPUTE_INT. Fix wrong statements on Default

8505 * NEWS: Document previous change.
8507 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8509 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8510 Require that long long int be at least 64 bits wide. C99 requires
8511 this and enough programs depend on it so we should check for it.
8512 Bruno Haible reports in
8513 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8514 that long long int is 32 bits wide with some nonstandard compilers.
8515 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
8517 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
8519 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8520 to a nonexistent file, so that we don't have to worry about
8521 a local site configuration that doesn't use /usr/local.
8522 Problem reported by Keith Marshall in
8523 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8525 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8527 * doc/autoconf.texi: Be more consistent about using @acronym with
8528 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8529 quite right (it talked about "OSF/Tru64", even though the
8530 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8531 and it even mentioned "OSF 4"!) and at this point there's little
8532 reason to talk about OSF any more, since it died in 1994.
8533 (Specific Compiler Characteristics): Simplify example of
8534 negative-size array.
8535 (File Descriptors): Reorder to make the text flow better.
8536 Remove joke about "appreciate the various levels"; I didn't get it.
8537 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8538 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8539 (File Descriptors, Limitations of Usual Tools):
8540 Tone down the advice against renaming or removing open files.
8541 (Limitations of Usual Tools): Add a new section, on 'rm'.
8543 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8545 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8546 -lXt in LIBS, idea from Karsten Hopp; this was due since
8549 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8550 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8551 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8552 (which belong to Xt, not X itself). See Debian bug 327655.
8554 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8556 * configure.ac (AC_INIT): Bump to 2.60a.
8559 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8563 * configure.ac, NEWS: Update.
8565 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8567 * config/texinfo.tex: Sync from upstream.
8569 * bin/autom4te.in (handle_traces): Transform the `@S|@'
8570 quadrigraph correctly in traces.
8572 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
8575 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
8576 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8578 * doc/autoconf.texi (Changed Directory Variables): New node,
8579 to document the whole `datarootdir' business a bit better.
8581 * tests/torture.at (datarootdir workaround): Extend test.
8582 Prompted by report by Alexandre Julliard.
8584 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8586 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8587 when using default mode of IBM C 6 for AIX. Problem and two-line
8588 fix reported by Larry Jones.
8590 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8592 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8593 about literal '${datarootdir}' if a definition is found in the
8596 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8598 * NEWS: Use "M4" rather than "m4" when appropriate.
8599 Problem reported by Eric Blake.
8600 * doc/autoconf.texi: Likewise.
8601 Use @acronym around BSD, GCC, and GNU when appropriate.
8602 (Why GNU M4): Renamed from "Why GNU m4".
8603 (Redefined M4 Macros): Mention that Posix
8604 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8605 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8608 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8610 * bin/autom4te.in (handle_output): Do not forbid the empty
8612 * tests/tools.at (autoconf: the empty token): New test.
8614 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8616 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8617 calls, so that we do not care whether they are LIFO or FIFO;
8618 in the m4_wrap, do not check which diversion is the topmost
8619 one, just check that the stack is balanced at the end.
8620 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8621 base diversion forever--pop the previous diversion before
8622 opening the new one; consequently, remove the m4_wrap call.
8623 * lib/autotest/general.m4 (AT_INIT): Likewise.
8624 * tests/m4sugar.at: Do not use
8625 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
8627 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8628 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8630 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8631 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8632 Rework example of m4wrap token-pasting trouble so that it doesn't
8633 care whether it's LIFO or FIFO.
8634 Fix some "contrary to"s that are awkward in English.
8636 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8638 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8639 to `yes' instead of `int$1_t' if the type is found, for more
8640 consistent configure output (where $1 is the number of bits).
8641 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8642 Suggested by Bruno Haible.
8644 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8645 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8646 with system headers. Report by Bruno Haible.
8648 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8650 * config/config.guess, config/config.sub: Sync from upstream.
8652 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8653 in order to avoid picking up an older installed frozen m4sh.m4f.
8654 Besides an outdated shell startup, this could have been created
8655 by an earlier M4 version with incompatible frozen file format.
8657 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8659 * README: Recommend m4 1.4.4 instead of 1.4.3..
8660 * doc/autoconf.texi: Likewise.
8661 (Special Chars in Names): Say that $(.FOO) is portable, as
8662 suggested by Stepan Kasal.
8663 (Installation Directory Variables, Build Directories):
8664 (Automatic Remaking, Subdirectories, Fortran Compiler):
8665 (Making testsuite Scripts, Defining Directories):
8666 Quote variable usages better.
8667 (Making testsuite Scripts): Add clean-local rule to makefile
8668 snippet, by Eric Blake.
8669 (Installation Directory Variables): Fix table item font.
8670 Reword slightly to clarify. Generalize advice about
8671 not using special characters to include all file-related
8672 vars, not just VPATH.
8673 (Special Chars in Variables): Warn about special characters in
8675 (Assignments): Clarify default-value example as suggested by
8677 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8678 (Special Shell Variables): Note leading ./ or ../, as suggested
8680 (Limitations of Builtins): Under cd, warn about CDPATH.
8681 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8684 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8686 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8687 `@var', for texi2html.
8688 (Systemology): Some more word wrapping, for DVI output.
8689 (autom4te Invocation): The short option for `--melt' is `-M',
8692 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8694 * doc/autoconf.texi: More formatting and English tweaks,
8695 many suggested by Ralf Wildenhues.
8696 Reword to avoid "@code{...}'s" and the like, since it's ugly
8697 with Emacs info mode. discontents -> woes.
8698 Put a few "will"s back. time stamp -> timestamp.
8699 side-effect -> side effect.
8701 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8703 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8704 Warn about $@ not persisting. Problem reported by Julien Danjou in
8705 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8706 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8707 Mention other special chars, too.
8709 2006-06-14 Eric Blake <ebb9@byu.net>
8711 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8713 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8715 * doc/autoconf.texi: Some systematic minor improvements, as
8716 follows. Use "makefile" when talking about makefiles
8717 generally (which might be named "makefile" or "Makefile" or even
8718 "foo.mk"), "Makefile" when talking about a specific makefile
8719 called "Makefile". This unclutters the text from weird quotes
8720 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8721 values" rather than "@var{foo}s" and similar constructs containing
8722 "}s". Use "Make rules" rather than "Makefile rules". Minor
8723 English-language improvements. Change the prefix "sub-" to "sub"
8725 Put blank lines around examples more consistently.
8726 Avoid "rather" and "very" as intensifiers.
8727 Avoid "will" as an auxiliary.
8728 (Limitations of Make): Split this node into....
8729 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8730 (Leading _ in Macro Names, Backslash-Newline-Newline):
8731 (Backslash-Newline Comments, Long Lines in Makefiles):
8732 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8733 (obj/ and Make, make -k Status, VPATH and Make):
8734 (VPATH and Double-colon, $< in Explicit Rules):
8735 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8736 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8737 New nodes, resulting from splitup of Limitations of Make.
8738 All cross-references changed. Raise the top node from
8739 a section to a chapter, and all subnodes accordingly.
8740 Redo the introductory wording to match the new organization.
8741 (Installation Directory Variables): Use an example that is
8742 closer to what Autoconf actually does. Mention that VPATH's
8743 value should not contain metacharacters or white space.
8744 (Fortran Compiler): Fix a VPATH bug in an example.
8745 (Leading _ in Macro Names): Mention that this problem is no longer
8746 of practical concern.
8747 (VPATH and Make): Reword the advice to make it clearer
8748 that Autoconf and Automake support VPATH in non-GNU make, but
8749 many packages have bugs in this area.
8750 ($< in Explicit Rules): Refer to Build Directories rather
8751 than using a (non-VPATH-safe) example.
8752 (Automatic Rule Rewriting): Mention the sort of disaster that
8753 can ensue with Solaris-style rule rewriting with VPATH.
8755 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8757 * doc/install.texi (Compilers and Options): Weaken the
8758 suggestion to use GNU make for VPATH builds.
8760 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8761 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8763 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8764 in regular expression.
8766 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8768 * doc/autoconf.texi (Installation Directory Variables):
8769 Drop extra @samp from `@table @samp' item.
8770 (Limitations of Usual Tools): Comment fix.
8771 Do not nest @samp just to point to other table items.
8772 (Writing testsuite.at) <AT_CHECK>: The second argument to
8773 `@dvar' is already @samp'ed.
8774 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8775 do not use @var in the second argument.

8779 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8780 $as_shell.exe too. Problem reported by Andreas Buening in
8781 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8783 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8785 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8786 `unused variable' compiler warning, for `-Wall -Werror'.
8787 Reported by Jaap Haitsma in
8788 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.

8792 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8793 case the compiler dumps core. Problem reported for
8794 OpenServer 5.0.7 by Tim Rice in
8795 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

8799 2006-06-06 Tim Rice <tim@multitalents.net>.
8801 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8802 "ERROR" only shows up in "make check" output if there is an

8826 * config/texinfo.tex: Sync from upstream.
8828 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8829 seen, invoke libtoolize with `--ltdl' argument.
8830 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8832 Suggested by Eric Blake.
8834 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

8850 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8851 message issued by AC_REQUIRE.
8852 * tests/m4sugar.at: Check m4_require's error message.
8853 * tests/base.at: Check AC_REQUIRE's error message.
8854 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8856 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8858 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8859 `expout' as the last parameter.
8860 * tests/tools.at: Adapt to the above change.
8862 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8864 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8865 information about race-free implementations of mkdir.

8874 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8876 * NEWS: GNU make now recommended for VPATH builds.
8877 Mention that some macros are now documented to be obsolescent.
8878 * doc/autoconf.texi:
8879 Prefer "current" to "modern" to describe
8880 currently-used (albeit perhaps old-fashioned) hosts.
8881 Mention which ancient features no longer need to be worried about.
8882 setgid -> set-group-ID
8883 setuid -> set-user-ID (these are the Posix terms)
8884 Fix some misuses of "only".
8885 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8886 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

8895 (Installation Directory Variables): shall -> should
8896 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8897 Mention that it's now safe to use 3 and 4.

8899 Omit longwinded and obsolescent discussion of cp -f.
8900 Modernize discussion of expr, ls.
8901 (Limitations of Make): Modernize discussion of VPATH builds.
8902 Mention $? as a workaround in some cases.
8903 * doc/install.texi (Basic Installation):
8904 Mention "./configure; make; make install" first. Be more
8905 specific about why this file is generic. Remove unnecessary
8906 parens. Remove misleading "only". Remove obsolete advice
8907 about csh. Don't say "configure" takes awhile; say it
8908 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8909 and CC=c99 rather than CC=c89, as these are blessed by current
8910 Posix. Recommend GNU make if doing a VPATH build.
8912 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8914 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

8933 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8935 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8936 about quoting the case statement, just in case.

8952 argument with leading hyphen. Problem reported by Paul Eggert.
8954 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8956 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8957 about quoting ac_try: quote all of it, if any of it seems suspicious.
8958 This means we don't have to worry about ${ or sed any more.
8959 Also, double-quote the case statement, to work around misuses via
8960 underquoting as reported by Ralf Wildenhues in
8961 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8962 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this

8977 Problem reported by Ralf Wildenhues in
8978 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8979 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8980 pre-2006-05-26 definitions, but leave in the comments that
8981 these macros are dangerous and should not be used.
8982 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8983 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8984 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.

8988 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8990 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8991 the use of 'tr', since this is our only use of 'tr'.
8993 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8994 and Paul Eggert <eggert@cs.ucla.edu>
8996 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

8999 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9001 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9002 the output file in the `${datarootdir}' test.
9004 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9005 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9007 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9008 mention of `datarootdir' in the input file(s), but literal
9009 `${datarootdir}' in the output file, and we haven't warned yet,
9010 then warn as well: the user may have (erroneously) used
9011 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9012 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9013 * tests/torture.at (datarootdir workaround): Extend this test.

9017 and Paul Eggert <eggert@cs.ucla.edu>
9019 * doc/autoconf.texi (autoheader Invocation): The first argument to
9020 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9021 alternatives and clear up the language a bit.
9023 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9025 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9026 ac_config_guess, ac_config_sub, ac_configure.
9027 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9028 Fix typo that prevented an unnecessary space from being removed.
9029 Problems reported by Ralf Wildenhues in:
9030 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9032 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9034 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9035 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9036 Don't use the term "thread-safe" to talk about mkdir race
9037 conditions, since the problem is more a process than a thread
9038 issue. Problem reported by Stepan Kasal in:
9039 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9040 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9041 the test for 'install' more closely. Look at MKDIR_P first.
9042 Look in the PATH, and at /opt/sfw/bin.
9043 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9044 Don't bother to try mkdir -p, since we already check mkdir --version;
9045 just look at the version number. (There's no easy way to check
9046 for race-free implementations.)
9047 * tests/tools.at (autoconf: subdirectories): Adjust to above
9048 changes, since MKDIR_P now might end in "/mkdir -p".
9050 * doc/autoconf.texi (autoheader Invocation): Mention that the
9051 first arg of AC_DEFINE_UNQUOTED must be a literal.
9052 Problem reported by Ben Pfaff in
9053 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9055 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9056 * doc/autoconf.texi (Special Chars in Variables): New section.
9057 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9058 (Installation Directory Variables): Quote $(datadir) better.
9059 (Limitations of Builtins): Describe some of eval's trickiness.
9061 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9062 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9063 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9064 in front of every arg, not just trailing args. Quote apostrophes.
9065 (_AC_EVAL_ECHO): New macro.
9066 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9067 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9069 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9070 exposed by quoting of eval argument. Put the command on line line
9072 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9073 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9074 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9075 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9076 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9077 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9078 Use eval more safely.
9079 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9080 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9082 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9083 lines, exposed by quoting of eval argument.
9085 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9086 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9088 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9089 initialization of `ac_cv_exeext', do not override it if it was
9090 already set, unless it was set to `no', for compatibility with
9091 Autoconf-2.13, and comment this.
9092 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9093 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9094 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9095 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9096 Document that this test may be overridden by setting
9099 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9101 Revert these two patches:
9103 2006-04-06 Eric Blake <ebb9@byu.net>
9104 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9105 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9108 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9109 Clean up _AC_COMPILER_EXEEXT* macros.
9110 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9111 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9112 ac_file to the name of the default output file and call
9113 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9114 initial `rm' of the candidate files...
9115 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9116 the same list in subsequent `rm' calls, and for the temporary
9117 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9118 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9119 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9120 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9121 no longer needed) by libtool. Make it a cache check.
9122 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9123 copied here by mistake.
9124 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9125 _AC_COMPILER_EXEEXT.
9126 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9127 _AC_COMPILER_OBJEXT directly.
9128 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9130 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9132 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9133 Fix description of how the buggy `sed' works.
9135 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9139 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9140 ENOLCK. Only mention `make -j' when applicable. Only raise
9141 fatal errors when `make -j' is involved. Improve error message.
9143 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9145 * doc/autoconf.texi (Here-Documents): We now know more about
9146 the variable expansion in here documents bug.
9147 Thanks to Tim Rice and Stepan Kasal.
9149 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9150 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9152 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9154 * tests/autotest.at (Multiline command from M4 expansion):
9155 No failure to be expected if the shell quotes newlines in
9156 commands in the `set -x' output. Report by Tim Rice.
9159 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9161 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9162 expansion in the here-documents used by config.status, as that
9163 runs afoul of the Korn shell version M-12/28/93d bug described in
9164 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9165 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9166 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9168 2006-05-23 Jim Meyering <jim@meyering.net>
9170 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9171 Fix typo introduced with 2006-04-02 change. It reversed the sense
9174 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9176 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9177 ac_dB slightly, to save bytes in the script.
9178 Max out at 50 lines, rather than 96; this is more likely
9179 (though not guaranteed) to avoid obscure 'sed' failures.
9181 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9183 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9184 `tr -d -' as bad option argument. Work around this by deleting
9185 an unrelated character.
9186 Report by Tim Rice <tim@multitalents.net>.
9188 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9189 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9190 Stepan Kasal <kasal@ucw.cz>
9192 * doc/autoconf.texi (Particular Programs): Do not promise that
9193 we always prefer the GNU version of the program, and that we
9194 search according to PATH; both rules can have exceptions.
9195 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9196 AC_PROG_SED. Move descriptions of limitations
9197 to the Limitations of Usual Tools section.
9198 (Limitations of Usual Tools) <sed>: Mention script length
9199 limitations with Solaris /usr/ucb/sed.
9200 <grep>: Fix wording for empty alternative. Mention that -c and
9201 -l should not be combined, and that -E and -F should not be
9204 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9205 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9207 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9208 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9210 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9212 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9213 AC_DEFINE is now passed to m4_pattern_allow.
9214 * NEWS: Mention that; likewise for AC_SUBST.
9215 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9216 the parameter to m4_pattern_allow.
9217 * tests/tools.at: Add a check for that.
9219 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9221 * lib/autoconf/status.m4: Fix typos.
9223 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9225 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9226 only the files that this macro generates.
9228 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9230 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9231 the HP-UX sed limitation of 99 commands, labels do not count.
9232 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9234 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9236 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9238 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9239 Import the following fix from coreutils:
9241 2006-01-13 Jim Meyering <jim@meyering.net>
9243 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9244 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9245 not double-quote uses of that variable, to accommodate the rare
9246 case in which getmntent is available in none of the libraries
9247 checked. This happens at least on FreeBSD 5.0.
9249 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9251 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9252 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9253 some other programs unwisely rely on these undocumented vars.
9254 But put in warning comments about them.
9255 Problem reported by Ralf Wildenhues in
9256 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9257 * NEWS: Document that these variables are intended to go away.
9259 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9261 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9262 and set the language to C++ (analogous to the equivalent Fortran
9265 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9266 * doc/autoconf.texi (C++ Compiler): Document it.
9267 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9270 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9272 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9273 that caused config.status to generate 100-command sed scripts; the
9274 portable limit is 99.
9276 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9278 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9279 variable `ac_d' instead of `d' to avoid infringing namespace.
9280 Report by Ralf Menzel.
9282 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9284 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9285 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9286 * tests/tools.at (autoconf: subdirectories): New test, taken from
9287 the corresponding problem report by Ralf Wildenhues in:
9288 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9290 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9291 Quote some uses of shell variables if they might suffer unexpected
9292 globbing. This doesn't fix all instances of quoting problems that
9293 I found, just the easy ones that look safe.
9294 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9295 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9296 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9297 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

9305 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9307 * bin/autoreconf.in ($help): Reword according to the manual.
9308 Suggested by Olly Betts.
9310 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9311 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9313 * bin/autoreconf.in: Pass the directory argument to
9314 `require_configure_ac'. Fix comment.
9315 * tests/torture.at (Configuring subdirectories): Expose this.
9316 Reported by Olly Betts.
9318 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9320 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9321 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9322 Automake as follows:
9324 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9325 `$configure_in' instead of `configure.in', to preserve
9326 directory component.
9328 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9330 * config/config.guess, config/config.sub, config/texinfo.tex,
9331 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9333 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9335 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9336 test for C99 conformance; (bool) 0.5 is an integer constant
9337 expression, but (bool) -0.5 is not. Problem reported by Fedor
9338 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9340 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9342 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9343 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9344 Warn about obsolete install-sh files. Remove stray sentence
9345 fragment and fix cross reference.
9346 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9347 install -d; this undoes the 2006-05-10 change.
9348 (MKDIR_P): Mark with AN_MAKEVAR.
9349 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9350 that we don't require $INSTALL to be thread-safe. Move comments
9351 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9352 of AC_PROG_INSTALL. Output a message saying that we're checking
9353 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9354 MKDIR_P instead of AC_SUBST.
9355 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9356 Special magic for MKDIR_P, too.
9357 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9359 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9361 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9363 Sync from Automake, as follows:
9365 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9366 * config/install-sh: Initialize IFS, so field splitting isn't
9368 * config/mkinstalldirs: Likewise.
9369 * config/missing: Remove superfluous quotes. Replace all uses of
9370 `[' by `test', for consistency, and for..
9371 * config/missing (sed_minuso, sed_output): New variables.
9372 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9373 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9374 Fixes `missing' to detect `--output' for help2man. Fixes
9375 PR automake/483. Report by Dennis J. Linse.
9376 (autom4te): Document in `missing --help'.
9378 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9380 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9381 * config/install-sh: Don't use 'path' to talk about file names,
9382 as per GNU coding standards. Close a race condition reported by Ralf
9383 Wildenhues and Stepan Kasal. There is still a race condition
9384 on hosts that predate Posix 1003.1-1992, but we can't help this.
9385 Don't mishandle weird characters like space on pre-Posix hosts.
9386 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9387 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9388 AC_PROG_MKDIR_P from AS_MKDIR_P.
9389 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9390 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9391 earlier editions are not (including Automake 1.8.3).
9392 Do not suggest mkinstalldirs for thread-safety.
9393 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9394 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9395 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9396 presence of special characters and race conditions.
9397 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9398 in Autoconf's name space.
9400 2006-05-10 Bruno Haible <bruno@clisp.org>
9401 and Paul Eggert <eggert@cs.ucla.edu>
9403 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9404 from Automake with minor changes.
9405 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9407 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9409 * config/install-sh: Update to Automake CVS version, as follows:
9410 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9411 * lib/install-sh: Simplify the expr implementation of dirname.
9412 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9413 * lib/install-sh: Handle --, and diagnose unknown options.
9415 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9417 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9418 `./autom4te' to create `./testsuite', since the `all' target
9419 will ensure its presence, but `installcheck' should not create
9420 the uninstalled wrappers.
9422 * tests/torture.at (Unusual Automake input files): Skip if we
9423 detect automake < 1.8.
9425 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9427 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9428 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9429 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9432 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9434 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9435 munge (multiple) white space and other oddities.
9436 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9437 single quotes in variable assignment.
9438 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9439 and similar failures by adding multiple spaces, tabs, and other
9441 Report and different test suggested by Francesco Romani
9442 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9444 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9445 single quotes, we only need to search for single quotes; this
9446 both simplifies the search pattern, and makes us less
9447 susceptible to `echo' variations for arguments not containing
9449 (_AC_ARG_VAR_VALIDATE): Likewise.
9451 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9453 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9454 `$*' and IFS concatenation issue with traditional shells and
9455 bash-2.04. Report by Seanster@Seanster.com.
9457 2006-05-03 Bruno Haible <bruno@clisp.org>
9459 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9460 precisely which Mac OS X versions have the od problem.
9462 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9464 * doc/autoconf.texi: Use @option systematically.
9466 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9467 and Bruno Haible <bruno@clisp.org>
9469 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9471 (Integer Overflow): Mention the special case of integer division
9474 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9476 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9477 traditional shells like the Solaris one that do not use the
9478 first IFS character for assembling `$*'.
9479 Prompted by a related report from autoconf_bug@nro.ca.
9481 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9482 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9485 Mention more problems with the -e option.
9487 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9490 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9492 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9493 in URLs to improve DVI formatted output (requires texinfo 4.6).
9494 (System Services, Systemology, Shellology): Likewise.
9495 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9498 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9500 (Runtime): Fix macro argument names to match description:
9501 `action-if-found' -> `action-if-true' and similarly.
9502 (Obsolete Macros): Likewise.
9503 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9504 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9505 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9507 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9509 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9512 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

9539 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9540 since as_me isn't set yet.
9542 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9544 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9545 a few minor bugs in this area.
9547 * doc/autoconf.texi (Programming in M4sh): Comment out the
9548 documentation of AS_BASENAME, for now.
9549 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9550 (Limitations of Builtins) <basename>: Do not refer to
9552 * bin/autoconf.as (me): Don't use AS_BASENAME.
9553 (dir): Remove the unused variable.
9554 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
9555 AS_DETECT_REQUIRED. All uses changed.

9568 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9570 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9571 of "run time" and "run-time" changed to "runtime", for consistency.

9578 with more accuracy and detail.
9580 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9582 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9583 Archive is not officially `GNU' any more. Update URL.
9584 (Defining Directories): Likewise
9585 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9587 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9589 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9590 newline from the `trap' code to finish `config.log'; the NetBSD
9591 /bin/sh resets the exit status after an empty command, as
9592 documented in doc/autoconf.texi.
9593 Reported by Dalibor Topic <robilad@kaffe.org>.
9595 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9597 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9598 Suggested by Bruno Haible.
9600 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9602 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9603 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9604 Instead, just list the shells that we know work.
9605 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9606 changed. Be more cautious about the _cv_ variable.
9607 * tests/tools.at (Syntax of the shell scripts): Check the
9608 _cv_ variable once, at first, to avoid an internal autoconf error
9609 when sh -n does not work.
9611 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9613 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9615 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9617 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9618 use ">&-" since we're only 99.999% sure that this is portable,
9619 and since the MinGW bug is fixed in a different way.
9620 * lib/autotest/general.m4 (AT_INIT): Likewise.
9622 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9624 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9625 before opening config.log, to avoid hitting a bug on MinGW.
9627 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9629 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9630 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9631 This works around a MinGW bug reported by Eric Paire.
9632 Make sure that all writes to the log file append to it,
9633 rather than possibly losing data.
9634 * lib/autotest/general.m4 (AT_INIT): Likewise.
9636 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9638 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the

9647 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9651 * Makefile.maint (news-date-check): Do not require a leading `*'
9652 before the release date in NEWS.
9654 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9655 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9657 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9658 the instantiated file do not contain the string 'datarootdir'
9659 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9660 @mandir@, replace the reference '${datarootdir}' by the value.
9661 * tests/torture.at (datarootdir workaround): New test.
9662 * NEWS: Advertise this temporary fixup.
9663 Based on a patch by Bruno Haible, reported and analyzed by
9664 Paul Eggert and Noah Misch.
9666 2006-04-12 Eric Blake <ebb9@byu.net>
9668 * tests/autotest.at (Debugging a failed test): Fix comment.
9670 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9672 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of

9677 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9678 succeeded, but `ln -s file dir' failed, take care to remove the
9679 leftover target before the next test, to prevent its spurious
9680 failure; also make sure `ln file dir' works before selecting it.
9681 Thanks to Keith Marshall for pointing this out.
9684 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9685 assignments in `at_debug_args', so that we put them correctly
9686 in the `run' script.
9687 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9688 Reported by Eric Blake.
9690 2006-04-11 Eric Blake <ebb9@byu.net>
9692 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9693 top-level tests after micro-suite has been run. Used in...
9694 (Debugging a successful test, Debugging script and environment),
9695 (Debugging a failed test): ...these new tests. The first of these
9697 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9698 macro, split out from...
9699 (AT_INIT): ...here, so that using -d also generates a run script.
9700 Document that -d inhibits top-level logging.
9701 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9702 inhibits top-level logging; debug scripts are created.
9704 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9706 * tests/autotest.at (Empty test, Empty check): New test to check it.
9708 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9711 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9713 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9714 the files if a problem appears. Make the empty *.at files
9715 read-only, too. Proposed by Ralf Wildenhues.
9717 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9719 * config/Makefile.am: Add comment to force updated Makefile.in.
9721 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9722 space only patch to this file, this patch causes the Makefile.in
9723 files that include freeze.mk to be updated, and thus have a
9724 newer time stamp again, which in turn makes a pristine CVS
9725 checkout have correct time stamps.
9727 * Makefile.maint (cvs-sv): New macro, to be used..
9728 (config.guess-url_prefix, config.sub-url_prefix)
9729 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9730 point to CVS text checkout of Gnulib files.
9731 (copyright-check): Bump current year.
9732 (announcement): Do not hard-wire `./announce-gen'.
9733 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9735 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9737 (wget_files): Update config.guess, config.sub, texinfo.tex by
9738 `wget-update', now that their URLs work again.
9740 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9742 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9743 Problem noted by Paul D. Smith.
9745 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9747 * doc/autoconf.texi: Remove unused words from word list.
9748 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9749 .x-sc_trailing_space: New files.
9751 * doc/standards.texi: Sync from gnulib.
9753 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9754 `LIBOBJDIR' as experimental.
9756 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9757 with a target directory; it's internally implemented as `cp'
9758 anyway, but since Autoconf advertises the possibility to use
9759 a target directory when LN_S is `ln -s', we need to find out.
9760 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9761 analyzed by Keith Marshall <keith.marshall@total.com>.
9765 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9767 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9768 confdefs.h as-is. In general, if it has backslash-newline or the
9769 like, then it doesn't work either to sort or to remove empty
9772 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9774 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9776 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9778 * lib/autom4te.in (Automake-preselections): Preselect
9781 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9784 apostrophe within a single-quoted string, as this is the usual
9785 tradition and is easier to read than '"'"'. Don't rely on the
9786 shell treating "$/" like '$/'. Use a more-consistent indenting
9789 2006-04-09 Eric Blake <ebb9@byu.net>
9791 * tests/autotest.at (Backquote command substitution),
9792 (Multiline backquote command substitution): Remove mistaken
9793 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9795 (Parenthetical command substitution, Multiline parenthetical
9796 command substitution): here.
9798 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

9873 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9875 Revert the patch from 2006-04-01 and only improve
9876 _AS_DETECT_BETTER_SHELL:
9878 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9879 skip nonexistent directories.
9880 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9881 only shell candidates which exist.
9882 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9883 * lib/autotest/general.m4 (AT_INIT): No need to give three
9884 parameters to _AS_PATH_WALK.
9886 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9887 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9889 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9890 distinguish m4sugar macros.
9891 * tests/tools.at (autoupdating with aclocal and m4_include):

9893 test case by Noah Misch <noah@cs.caltech.edu>.
9895 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9897 Revert my change from 2006-03-17, in other words:
9898 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
9900 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

9904 2006-04-07 Eric Blake <ebb9@byu.net>
9906 * doc/autoconf.texi (Programming in M4sh): Document that
9907 AS_MKDIR_P exits the script on failure.
9908 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9910 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9912 * config/elisp-comp, config/install-sh, config/mdate-sh,
9913 config/missing, config/mkinstalldirs: Sync from Automake.
9915 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync

9927 Eric Blake <ebb9@byu.net>,
9928 Paul Eggert <eggert@cs.ucla.edu>,
9929 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9931 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9932 whether `set' quotes correctly: redirect stderr of the tested
9933 `set', and use a subshell, for Ultrix; use `sed' instead of
9934 `grep' for zsh `set' which may write binary output; match only
9935 at the beginning of a line, to avoid false positives.
9936 In order to avoid false positives by unrelated variables with
9937 multiline content, put the dump algorithm in a subshell and
9938 unset all variables containing newlines (except some which are
9939 special to the shell). Warn about cache variables that are
9942 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9944 * config/config.guess, config/config.sub, config/texinfo.tex:
9947 * tests/mktests.sh: Reword comments.
9949 * tests/mktests.sh: Only skip internal macros starting with

9956 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
9958 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
9959 shell issue with double-quoted command substitutions of native
9961 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith

9985 ac_config_<foo>s again, sometimes normalized, sometimes not.
9986 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9987 (AC_CONFIG_COMMANDS): Do not do so here.
9988 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9989 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
9990 2005-07-25 rewrite. Noticed by Noah Misch.
9992 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
9993 _AC_PRESERVE_HELP_ORDER, ...
9994 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9996 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9997 inside m4_expand_once; it is redundant.
9999 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
10000 for --help from Cygnus `configure.'
10002 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
10004 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up

10012 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
10013 Noah Misch <noah@cs.caltech.edu>
10015 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
10016 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
10017 * doc/autoconf.texi (Help Formatting): New node.
10018 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
10020 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10022 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
10023 lib/autoconf/specific.m4, lib/autoconf/status.m4,
10024 lib/autoconf/types.m4, lib/autotest/general.m4,
10025 tests/mktests.sh, tests/torture.at: White space cleanup:
10026 remove some SPACE before TAB, or add quoting ('' or @&t@).
10028 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
10030 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
10032 2006-04-05 Eric Blake <ebb9@byu.net>
10034 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
10035 empty test suite works.
10036 * tests/autotest.at (Empty test suite): Remove xfail.
10038 2006-04-05 Noah Misch <noah@cs.caltech.edu>

10044 normalizing it, consistent it with previous releases.
10045 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10047 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10049 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
10050 Use simplified args that Eric Blake originally suggested.
10052 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
10054 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10055 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10056 Use 'comm' rather than N instances of grep; this also fixes a bug
10057 whereby substrings were incorrectly matched, causing us to not
10058 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10059 (exclude_list): Exclude empty macros.
10060 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

10069 2006-04-04 Noah Misch <noah@cs.caltech.edu>
10071 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
10072 a subdirectory subject to Cygnus `configure'.
10073 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
10075 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
10076 report request when we have no AC_PACKAGE_BUGREPORT.
10078 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10082 * tests/mktests.sh: Update copyright year in the header of the
10085 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
10086 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
10087 typedef'ed restricted pointer, to catch a compiler bug on
10088 HP-UX 11.x, and fix warnings so it passes with -Werror.

10104 2006-04-03 Eric Blake <ebb9@byu.net>
10106 * THANKS: Add myself.
10108 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10110 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
10111 to log, point to testsuite output tree.
10113 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
10115 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

10936 comparing its address. Intel's interprocedural optimization was

10988 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10990 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10991 calls, so that the final expansion of this macro is shorter.
10992 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10993 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10994 the cleanup there. Use AS_VAR_* macros, to be more general.
10995 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10997 * lib/autoconf/general.m4: Use AS_IF where appropriate.

11024 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11025 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

11037 some evil values and relying on the fact that $* concatenates the
11038 parameters by the first character from IFS.
11040 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11041 Stepan Kasal <kasal@ucw.cz>
11043 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11044 first header appears, define AH_HEADER.
11045 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11046 Update limitations about when to call AC_CONFIG_HEADERS.
11047 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11048 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11049 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11050 ``Configuration Actions''; fix their index entries.
11052 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11053 options correctly. Process N-M as M-N if M is smaller than N.
11054 Process ranges correctly so that N-N will run only N.
11055 Sort and uniquify the tests that will be run. If there is more
11056 than one test, reinsert the banners for the tests.
11057 * tests/autotest.at (Keywords): Unmark XFAIL.
11059 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11061 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11062 before passing the macro name to AH_TEMPLATE.
11064 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11065 now opens log after option processing; in particular, --version
11066 and --help do not touch config.log.
11068 * Makefile.maint: Revert the change from 2005-08-12.
11070 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11072 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

11078 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11079 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
11082 * doc/autoconf.texi (Defining Symbols, Changed Results):
11083 Prepend to LIBS, not append, in examples.
11085 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11087 When building in place, set srcdir="."; suggested by Tim Van Holder.
11089 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11090 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11091 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11092 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11093 does not mean "no --srcdir option".
11095 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11097 * tests/autoscan.at (autoscan): New file.
11098 * tests/suite.at: Use it.
11099 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11100 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11102 * tests/autotest.at (Keywords): Test keywords combinations.
11104 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11106 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11107 add "2>&1"; gzip 1.2.4 prints help on stderr.
11109 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11111 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11112 was pushdef'ed twice while popped only once. Push it only once.
11113 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11115 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11117 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

11122 * Makefile.maint: Update from Bison.
11124 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11125 "<tab>" in comment, so that the point is understandable.
11127 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11129 Rewrite substantial part of lib/autoconf/status.m4.
11130 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11131 and CONFIG_COMMANDS are not processed in four separate loops.
11132 Instead, there is one main loop. This alows that the common code
11133 is expanded only once, thus config.status (and configure) is smaller.
11135 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11136 the AC_LIST_FILES and cousins macros are no longer used.
11138 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11139 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11140 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11141 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11142 contain the initialization, nor the for loop, nor the associated
11143 commands; all these go to ...
11144 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11145 _AC_OUTPUT_CONFIG_STATUS.
11146 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11147 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11148 (_AC_OUTPUT_FILE): The creation of the sed script ...
11149 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11150 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11151 _AC_OUTPUT_MAIN_LOOP.
11152 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11153 _AC_CONFIG_COMMANDS): Use ...
11154 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11155 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11156 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11157 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11158 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11159 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11161 (_AC_CONFIG_UNIQUE): Update.
11162 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11163 Replaced by this ...
11164 (_AC_LIST_TAGS): ... new common macro.
11165 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11166 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11167 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11168 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11169 this didn't belong to the `config commands' section.
11170 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11171 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11172 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11173 to the `config commands' section either.
11174 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11175 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11177 ... and many changes to the comments nearby.
11179 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11180 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11181 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11182 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11183 (#define header templates): The comment at the top of the generated
11184 header now includes the name(s) of the source file(s).
11186 Several unrelated small changes:
11188 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11189 parameter to AC_DIAGNOSE.
11190 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11191 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11192 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11193 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11194 with AU::AC_OUTPUT.
11195 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11196 in AC_OUTPUT doesn't double-quote it either.
11197 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11200 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11202 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11203 versions of Portland Group compiler produce single- and double-quoted
11204 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11205 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11207 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11209 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11210 This is a corrected version of yesterday's patch.
11212 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11214 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11215 path, too; insert a "===" to emphasize the line.
11217 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11218 ac_cv_build_alias to ac_build_alias.
11219 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11221 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11222 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11223 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11224 (AC_ARG_VAR): ... here.
11225 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11228 Keep a list of all precious variables and process them with one simple
11229 for loop, instead of expanding all commands, or, OTOH, complicated
11230 processing of output of "set".
11231 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11232 variable names in new macro...
11233 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11234 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11235 a loop to assign all ac_env_* and ac_cv_env_* variables.
11236 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11238 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11239 its value to shell variable ac_precious_vars and call
11240 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11241 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11242 _AC_ARG_VAR_VALIDATE.
11244 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

11262 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11263 They are generated by the Tru64 v5.1B shell.
11265 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11267 Fix my changes from 2005-07-01; reported by Noah Misch.
11268 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11269 description, the macro now accepts only a single tag.
11270 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11272 Fix cases when the varsions of Autoconf and Autotest don't match.
11273 Reported by Noah Misch.
11274 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11275 at_top_builddir, for compatibility with older autotest.
11276 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11277 is not set, use at_top_builddir, for compatibility with older
11278 versions of autoconf.
11280 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
11282 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11283 Problem reported by Patrick Welche.
11285 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11287 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11288 sed substitution command, so that we allow | in program prefixes
11289 and program suffixes. (& is a problem anyway; we're not fixing
11291 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
11292 configure_input, top_builddir, srcdir, etc.
11293 * lib/autotest/general.m4 (AT_INIT): Likewise, for
11294 PATH_SEPARATOR in AUTOTEST_PATH.
11296 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11298 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11299 for loop over config.site files using `set', to allow
11300 directory names containing IFS characters.
11302 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11304 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11305 directories with weird names. Apparently some people like living
11306 on the edge. However, improve the test that "pwd" actually does
11307 report a name for the working directory.
11308 * NEWS: Remove the claim that we test for funny chars in dir names.
11310 2005-07-01 Stepan Kasal <kasal@ucw.cz>

11323 (Generic Functions): Mention the Gnulib project.
11324 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
11326 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11327 document to output the default config_* lists to config.status.
11328 Don't recognize option --file, if the functionality is not there.
11329 Likewise for --header; moreover, recognize --he and --h as shortcuts
11330 for --help in that case.
11332 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11333 matches the order of execution. No code changed.
11335 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11337 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

11352 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11354 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11355 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11356 (AC_SUBST): Call it.
11357 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11358 the directory specific variables; but don't call it for configure_input.
11360 2005-06-28 Derek Price <derek@ximbiot.com>
11362 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11365 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11367 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11368 directory have inherent problems with special characters like spaces,
11369 due to limitations in Make syntax. Problem reported by Alexandre
11371 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11372 Also, fix Tru64 porting problem with shell patterns,

11383 Fix some more shell quoting problems. Prompted by a bug report
11384 from Justace Clutter.
11385 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11386 variable into diagnostic. Make the diagnostic an error, not a warning,
11387 because we really don't support spaces and suchlike in dir names.
11388 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11389 Don't worry about backslashes in srcdir; it can't happen now.
11390 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
11391 Simplify ac_optarg handling.
11392 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

11399 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
11400 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11402 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11403 that '\|' is not allowed in BREs; recommend using newline separated
11404 list of patterns instead of multiple -e options.
11406 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11408 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11414 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11416 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11417 b, t, r, w commands require single space, while : cannot have any.
11418 (Special Shell Variables): Fix sed code this in the example.
11419 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11420 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11422 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11423 expand to the empty list. Don't use two pairs of m4_changequote,
11424 it's not necessary.
11426 2005-06-20 Derek Price <derek@ximbiot.com>
11428 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11430 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11432 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11433 * doc/autoconf.texi:
11434 Don't mention Solaris versions so much, if a
11435 problem is common to all extant versions of Solaris. Say "SunOS
11436 4" instead of "SunOS" for SunOS 4.
11437 (awk): Mention more of the limitations of traditional Awk.
11438 (cat): Don't talk about cat -v.

11442 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
11443 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
11444 but the implementation is entirely different and is designed
11445 to be compatible with glibc strverscmp.
11446 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11448 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
11449 on Mac OS X 10.4 reported by Peter O'Gorman in:
11450 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
11451 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11452 Use shell builtins rather than 'expr', to work around expr bug.
11454 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11456 * doc/autoconf.texi: "filesystem" -> "file system".
11457 "behaviour" -> "behavior".
11458 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11459 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11461 * lib/m4sugar/m4sh.m4: Likewise.
11462 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11463 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
11465 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
11466 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11467 to update the man page. That way, we don't have to check in new
11468 man pages every month.
11470 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11471 quotes and backslashes. Patch from Derek Price.
11473 2005-06-10 Derek Price <derek@ximbiot.com>
11475 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
11478 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
11480 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11481 -u, since it outputs chatter if the input files are the same.
11482 Problem reported by Ralf Menzel.
11484 2005-06-08 Derek Price <derek@ximbiot.com>
11486 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11487 renaming them since they are about to be redefined anyhow.
11489 2005-06-08 Derek Price <derek@ximbiot.com>
11491 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11492 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11493 Move m4_undefine to alphabetical order.
11495 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11497 * README: Recommend GNU M4 1.4.3 or later.
11498 * doc/autoconf.texi (Introduction): Likewise.
11499 Reword to avoid some formatting glitches.
11500 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11501 Clarify explanation of HP compiler bug.
11502 Redo example output tp match current CVS snapshot.
11503 Use @example.org in email addresses when the examples
11504 might get inadvertently cut-and-pasted into user code.
11505 Remove example of autom4te usage that doesn't seem to work now.
11506 Use modern AC_INIT (except when the example is meant to be
11507 shown with Autoconf 2.13).
11508 Update ksh info for Solaris 9 and later.
11510 Modernize description of Automake versions a bit.
11511 Don't claim a future version of Autoconf is near.
11512 * doc/install.texi: Reword to avoid some formatting glitches.
11514 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11516 * doc/autoconf.texi: Add [] to examples, so that the manual
11517 follows its own advice about quoting better.
11518 Reword to avoid some formatting glitches.
11519 * doc/installt.exi: Reword to avoid some formatting glitches.
11521 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11522 Tru64 ksh pattern matching bug. Reported against Libtool by
11523 Albert Chin <libtool@mlists.thewrittenword.com> and
11524 Nicolas Joly <njoly@pasteur.fr>.
11526 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11528 m4_cdr of one-member list was [[]] (one-member list containing an
11529 empty string) instead of [] (an empty list. Callers were skewed to
11530 match this misbehaviour. As a consequence of this:
11531 - m4_foreach([x], [], [foo]) expanded to `foo', while
11532 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11533 This bug has been fixed:
11535 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11536 expand to an empty string; print error msg if called without
11538 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11539 misbehaviour; handle [] and [[]] correctly.
11541 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11543 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11544 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11545 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11547 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11549 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11550 swallow records with more than 99 fields.
11551 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11552 parse the long line.
11554 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11556 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11557 swallow literals longer than 399. Reported by Ralf Wildenhues.
11558 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11559 to workaround this limitation.
11561 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11563 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11564 to gfortran, and make these the first two compiler names
11565 checked (following the general autoconf preference for gcc).
11567 2005-06-03 Stepan Kasal <kasal@ucw.cz>
11569 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11570 (DISTCLEANFILES): Remove $(check_SCRIPTS).
11571 (testsuite): Make sure autotest.m4f is up-to-date before using it.
11573 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
11575 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11576 expression of unbounded size when processing the --list
11577 option. This runs afoul of a limit of 399 bytes per regular
11578 expression on AIX. Problem reported by Ralf Wildenhues.
11580 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
11582 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
11583 * doc/autoconf.texi (Particular Headers): Reword example
11584 for multiline stdbool replacement.
11585 (Setting Output Variables): Reword text a bit. Don't
11586 give all the details about |#_!!_#|.
11587 Reword description of line replacement.
11589 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11592 now contain newlines, and substituted files must be referenced on
11593 a line alone; the sed scripts to substitute them are now very
11595 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11596 commands can be put in a sed script portably.
11597 * doc/autoconf.texi (Setting Output Variables): Document above
11598 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
11599 use of multiline substitution.
11600 * tests/torture.at: No longer expect substitution of newline to fail.
11602 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
11604 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
11605 From Ralf Menzel (trivial change).
11607 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11609 * tests/local.at: Don't attempt to check for negated character
11610 classes in shell scripts. The test was too brittle.
11612 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11614 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
11615 * doc/autoconf.texi (Limitations of Builtins): Document this
11618 2005-05-24 Stepan Kasal <kasal@ucw.cz>
11620 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
11621 common code; used in many places in the tree.
11622 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
11623 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
11625 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
11627 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
11628 messages when ac_unique_file is not found.
11629 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11630 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11631 commands, for consistency with AC_MSG_ERROR and such.
11633 * bin/autoconf.as: Make more use of "shift 2" in option processing.
11635 * bin/Makefile.am: Merge the two rules for creating scripts.
11637 2005-05-23 Stepan Kasal <kasal@ucw.cz>
11639 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
11640 obsolete; it was never documented.
11641 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
11643 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11645 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
11646 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
11647 (ac_top_builddir): ... this ...
11648 (ac_top_build_prefix): ... to this; the old name is also kept, for
11649 backward compatibility.
11650 (ac_top_builddir_sub): New variable, without the trailing slash,
11652 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
11653 * doc/autoconf.texi (Configuration Actions): Rename
11654 ac_top_builddir to ac_top_build_prefix.
11655 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
11656 at_top_builddir to at_top_build_prefix.

11659 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11661 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
11664 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11666 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11667 argument to m4_foreach. I guess it was necessary in the past,
11668 but I think it's a no-op now.
11670 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11672 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11673 ``cat <<_ACEOF'' commands to one.
11674 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11675 * lib/autoconf/status.m4: On various places, use expr instead of
11677 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
11678 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
11679 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
11681 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11682 the wrong patterns between ``case'' and ``esac.'' The previous
11683 code had false positives.
11685 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11687 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

11747 abbreviations of --version and --debug.
11749 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
11751 * doc/autoconf.texi (Autoconf Language): Be more precise about
11752 quoting rules. Problems noted by Stepan Kasal.
11753 Also, throughout this document, be more careful about white space.
11754 "blank", "white space", and "space" all have different meanings
11755 and we should be careful to say what we mean.
11757 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
11759 Fix C++ related problems reported by Werner Lemberg.
11760 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

11762 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
11763 avoid problems with C++ and throw.
11764 * tests/compile.at: .cpp, not .cc.
11766 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
11768 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11772 2005-05-02 Gary V. Vaughan <gary@gnu.org>
11774 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
11775 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
11776 set by latest automake.
11778 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
11780 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
11781 outputs 0 on GNU/Linux these days.
11783 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
11785 * doc/autoconf.texi (Autoconf Language): Add more description
11786 about quoting heuristics.
11787 (Limitations of Builtins): Describe "set -" problems.
11789 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11791 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
11794 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11795 by AC_DEFINE; it was a mistake.
11796 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
11798 2005-04-25 Stepan Kasal <kasal@ucw.cz>
11800 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
11802 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11804 * doc/autoconf.texi (External Software): Quadrigraphs are not
11805 processed correctly in AS_HELP_STRING; avoid this in the examples.
11806 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11807 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11808 comment and reduce m4_default([foo], []) to [foo].
11809 (m4_strip): Update the explanation.
11811 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11813 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11814 Remove core.conftest.* too; it's generated by Tru64 5.1.
11815 Problem reported by Jennis Pruett.
11816 * lib/autoconf/functions.m4
11817 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11818 Don't bother to remove core files; AC_RUN_IFELSE should do that
11821 2005-04-19 Stepan Kasal <kasal@ucw.cz>
11823 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

11837 * doc/autoconf.texi (External Software, Package Options): Add
11838 examples showing how to implement --with-* and --enable-* options.
11840 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
11842 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac

11861 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
11863 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11865 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11866 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11867 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11868 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11869 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
11871 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
11873 * NEWS: The configure command now warns you if you attempt to use
11874 a directory whose name contains a special character like space,
11876 * doc/autoconf.texi (Installation Directory Variables): Allow
11877 "," in file names. Do not use \@; it's not a portable regexp.
11878 * bin/Makefile.am (edit): Likewise.
11879 * lib/Makefile.am (edit): Likewise.
11880 * tests/Makefile.am (edit): Likewise.

11887 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
11889 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
11890 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
11891 ac_pwd, and quote srcdir.
11892 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11894 * doc/autoconf.texi: Fix some systematic formatting problems.
11895 ".)" needs a following @: if not at the end of a sentence, and
11896 similarly for "!)". "etc." should be preceded by a comma.
11897 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11899 2005-03-22 Bruno Haible <bruno@clisp.org>
11901 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
11902 argument is often called 'build-aux'.
11904 2005-03-07 Stepan Kasal <kasal@ucw.cz>
11906 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
11907 macro AC_TRY_LINK is obsolete.
11908 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
11911 2005-02-24 Stepan Kasal <kasal@ucw.cz>
11913 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11914 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11915 from a Common Lisp's `cl'.
11916 (AC_PROG_CXX): Behave according to the documentation: don't
11917 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11918 make the variable CCC precious; use `cl.exe', not `cl'.

11921 Alexandre Duret-Lutz <adl@gnu.org>
11923 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11924 /dev/null, as "configure" shouldn't read stdin, and this insulates
11925 us from problems (e.g., when testing for "cl"). Also, do this
11926 redirection before invoking "hostname" or "uname", and keep the
11927 original input stream available via...
11928 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11929 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
11930 bother with "</dev/null" since it's now done at the top of

11939 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11941 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11942 newline if neither \c nor -n work, as that would output two
11943 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11945 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11947 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
11948 This causes that any required macros inside will get before the if.
11949 * doc/autoconf.texi (autom4te.cache): A typo.
11951 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11953 Undo previous change, except keep the change to
11954 lib/autoconf/programs.m4 that replaced grep with shell
11955 pattern-matching. This is because net-snmp configure reads stdin.
11956 Reported by Noah Misch.

11960 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11961 from /dev/null, as "configure" shouldn't read stdin, and this
11962 insulates us from problems (e.g., when testing for "cl").
11963 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11964 before invoking "hostname" or "uname".
11965 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11966 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11967 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11968 "</dev/null" since it's now done at the top of 'configure'.
11969 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11970 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11971 Also, replace grep with shell pattern-matching, to save a process.
11973 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
11975 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11976 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11977 avoid thinking that Allegro Common Lisp's "cl" command is a C++
11980 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
11982 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11983 grep -q isn't portable. Improve grep -s explanation.
11984 Problem reported by Dan Manthey.

11991 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11993 * doc/autoconf.texi: Use @acronym for DJGPP.
11994 Fix some @code's that should have been @env's, and vice versa.
11995 Sort environment variable names.
11996 Mention that shells no longer inherit IFS.
11997 Don't recommend PATH_SEPARATOR=';' so strongly.
11998 Mention that $RANDOM might expand to the empty string.
11999 "symlink" and "soft link" -> "symbolic link".
12000 Improve mktemp description (reported by Bruno Haible).

12014 * tests/local.at (AT_CMP): Use diff directly on input files rather
12017 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in

12037 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
12038 CPPFLAGS to `configure' instead of setting it in `configure'.
12040 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12041 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

12094 * doc/autoconf.texi (Special Shell Variables): Mention _,
12095 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12096 if they contain a lower-case letter. The DUALCASE problem was
12097 reported by Ralf Wildenhues.

12107 Unicos 9 sed limitations.
12108 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

12139 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12140 Update the long comment explaining it.
12142 m4_require no longer writes an ``is required by'' line to the
12143 execution stack. It contains only one bit of non-redundant
12144 information: that the macro was required, not called. And even
12145 this bit is useless in most situations: have you ever met a macro
12146 which both calls and requires the same macro?
12148 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12149 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12152 (m4_expansion_stack_pop): Remove the misplaced comment.
12153 (m4_require): Don't put the ``is required by'' line to the
12154 execution stack; slightly improve the out-of-a-defun error message.
12155 (_m4_divert_grow): New macro, counter for the temporary diversions.
12156 (_m4_require_call): Use it.
12157 * tests/m4sugar.at (m4_require): Expect output without the
12158 ``is required by'' messages.
12160 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12162 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

12180 from masters, so that FileUtils.pm's update_file provide --force
12182 * bin/autoheader.in: Pass $force to update_file so that
12183 config.h.in is always recreated when --force.

12189 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
12191 * doc/autoconf.texi (Limitations of Builtins): Clarify that

12194 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12196 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12197 Warn about newline stripping in `` and $(). Update Solaris
12199 (Limitations of Builtins): Use expr "X...", not expr "x...", as
12200 X insulates us from future changes to Posix.
12201 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
12204 2005-01-19 Stepan Kasal <kasal@ucw.cz>
12206 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

12249 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
12250 (_m4_divert_n_stack): New macro; the expansion is
12251 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
12253 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12254 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12255 stored in _m4_divert_diversion or _m4_divert_dump.
12256 (m4_divert_pop): When the parameter is given, compare the symbolic
12257 name with the last diversion pushed on the stack. Previously, the
12258 current diversion was compared with the numeric value of the
12259 diversion given as the parameter.
12260 (m4_require): If the macro hasn't been expanded yet, call ...
12261 (_m4_require_call): this new macro.

12294 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
12295 signals that the package uses Automake; a `Makefile.am' is typical but
12296 not essential. Reported by Magnus Therning.
12297 * tests/torture.at (autoreconf.): New banner.
12298 (autoreconf and non-AC configure): Rename to `Non-Autoconf

12341 * lib/autotest/general.m4 (AT_LINE): Don't add srcdir here, to
12342 avoid cluttering displayed messages. Rather, prepend srcdir where
12343 AT_LINE is used for log files.

12796 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12798 * lib/autom4te.in (Automake-preselections): Preselect
12799 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12802 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12804 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12806 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12807 Document problem with "`""`" in pdksh POSIX mode.
12809 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12811 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12812 with pdksh, too. Problem reported by Patrick Welche via
12814 * doc/autoconf.texi (Shellology): Note that set -o posix is
12815 useful for pkdsh, too.
12817 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12819 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12820 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12821 Don't fail if ENV or BASH_ENV is readonly.
12822 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12823 etc. are read only. Problem reported by Ludovic Courtes.
12825 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12827 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12828 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12831 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12833 * doc/autoconf.texi (File System Conventions): Warn about
12834 names like "aux". Problem reported by Eric Blake.
12836 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12837 by zero instead of array size, so that we can use any arithmetic
12838 constant expression (instead of requiring an integer constant
12839 expression). This allows us to test expressions like DBL_MAX <
12840 LDBL_MAX, which didn't conform to the C standard using the old
12842 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12843 now that we can do floating-point tests at compile time.
12845 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12847 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12848 and LDBL_EPSILON, as the resulting expression isn't an
12849 integer constant expression and violates the C standard.
12850 Problem reported by Nelson H. F. Beebe. Also, check
12851 for "L" suffix, and check that long double doesn't have
12852 worse range or precision than double, that mixed-mode
12853 arithmetic doesn't generate a diagnostic, that double
12854 constants fit in long double.
12856 2004-06-03 Kevin Ryde <user42@zip.com.au>
12858 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12859 malloc(0) and realloc(NULL,size).
12861 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12864 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12866 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12867 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12870 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12872 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12873 can be rewritten using if-then-else. Suggested by Bruno Haible.
12875 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12877 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12878 Problem reported by Stepan Kasal.
12880 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12882 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12883 change). Patch reported by Ralf Wildenhues in
12884 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12886 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12887 function F exists if the compiler and linker let you compile an
12888 expression like (F != 0). Recent versions of GCC optimize away
12889 the reference to F in that case, since every function address must
12890 be nonzero, so the link succeeds even if F does not exist.
12891 Problem reported by Manu in
12892 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12894 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12895 "Unix". Many uses changed.
12896 (Limitations of Builtins): Explain better why the ! command isn't
12899 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12901 * lib/autom4te.in (Automake-preselections): Preselect
12902 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

12906 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12907 referencing AC_FUNC_STRERROR_R.
12909 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12910 note pessimistic assumption when cross compiling.
12912 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12914 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12915 (until 2004) invoked subcommands with sh -e, contra POSIX.
12916 Reported by Kevin Ryde.
12918 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12920 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12921 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12922 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12923 `test -f " /usr/bin/grep"', which _always_ failed.
12924 (AC_PROG_SED): Ditto bogus PATH fix.
12925 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12926 requires that grep correctly supports _multiple_ `-e' options, rather
12927 than stating only that grep should accept `-e'.
12929 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12931 Port to C99, which requires that 'exit' be declared.
12933 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12934 to ensure that stdlib.h is included.
12935 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12936 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12937 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12938 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12939 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12940 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12941 when using 'exit' in a test; C99 requires that 'exit' be declared.
12943 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12945 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12946 now prefers 'grep' implementations that accept -e.
12947 (Limitations of Usual Tools): Describe problems of traditional
12948 egrep and fgrep with long input lines, and of traditional grep
12950 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12951 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12952 All callers changed. Append /usr/xpg4/bin to the PATH, for
12954 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12955 the user with complaints about multiple -e options.
12956 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12957 Define it with AC_PROG_GREP.
12958 * configure.ac (AC_PROG_GREP): Add.
12959 * lib/freeze.mk (GREP): New macro.
12961 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12963 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12964 a possible candidate only after all others fail, rather than
12965 consulting it first. This improves backward compatibility by
12966 better reflecting the way shell selection occurred in previous
12967 versions of Autoconf, and should help to avoid triggering latent
12968 problems in other packages, such as the one in Automake where zsh
12969 is not handled robustly:
12970 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12971 Although it is not Autoconf's responsibility to work around
12972 problems in Automake, it nevertheless makes sense to avoid
12973 introducing unnecessary incompatibilites.
12975 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12976 Gary V. Vaughan <gary@gnu.org>
12978 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12979 how deeply nested we are when a suitable tool is found, set the
12980 ac_path_TOOL_found flag.
12981 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12982 nested we are in this macro. Break out of all 3 nested loops if
12983 ac_path_TOOL_found is set.
12985 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12987 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12988 of the _AS_PATH_WALK loop too if GNU flavor is found.
12990 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12992 * doc/autoconf.texi (Limitations of Make): Update documentation
12993 for `$<'. New entry `Long lines', based on a report from Simon
12994 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12995 paragraph about DJGPP, based on a mail from Richard Dawe.
12997 2004-04-20 Paul Eggert <eggert@twinsun.com>
12999 * tests/c.at (C keywords): Don't assume that GCC supports
13000 "restrict" and "inline", as sufficiently-old GCC versions do not
13001 (also, GCC configured to be in pedantic C89 mode does not).
13002 Problem reported by Sumit Pandya in:
13003 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13005 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13006 consider -g to work if it generates warnings when plain compiles
13007 don't. Problem reported by Braden McDaniel in:
13008 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13010 * doc/autoconf.texi (Slashes): New section, to document a problem
13011 reported by Jim Meyering in:
13012 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13014 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13015 linker output files before linking, to work around IRIX 6 linker bug.
13016 Problem reported by Rainer Orth in:
13017 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13019 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13021 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13022 best tool so far counter rely on the tool path variable name to
13023 avoid checks for one tool being affected by the results of running
13024 the length check on a previous tool.
13026 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13027 match expression argument, as different greps have different
13028 regular expression flavours.
13029 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13031 (AC_PROG_EGREP): Pass 'EGREP$'.
13032 (AC_PROG_GREP): Pass 'GREP$'.
13034 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13036 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13037 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13039 2004-03-29 Paul Eggert <eggert@twinsun.com>
13041 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13042 Types, Specific Compiler Characteristics, System Services,
13043 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13044 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13045 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
13046 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

13059 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13060 now defines HAVE_DECL_TZNAME if it is declared, when
13061 HAVE_STRUCT_TM_TM_ZONE is not defined.
13062 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13063 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
13066 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
13068 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13069 superfluous backslashing of quotes (") in sed expressions;
13070 thanks to Paul Eggert.
13072 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
13074 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
13075 Fortran compiler is ifort, also added pghpf; thanks to Nelson
13076 H. F. Beebe for the bug report.

13123 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

13132 * bin/Makefile.am (edit): Don't use $< in a context where
13133 POSIX doesn't require support for it. Use $@.in instead.
13134 Problem reported by Anthony N. Frasso in
13135 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

13164 AC_SUBST provides no portable way to escape literal newlines.
13166 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13167 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13168 Darwin uses -lcrt2.o and there's little point to cataloging all
13169 the system variants. Partial fix reported by Andreas Waechter in:

13245 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
13246 2003 (except 1997) to the list of copyright years. This undoes
13247 the 2003-05-22 change, which removed the older years from the list.
13248 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13254 grep or ggrep program in PATH that accepts as long lines as
13256 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

13259 egrep and fgrep respectively if $GREP -E/-F don't work.
13260 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13261 _AC_PROG_GREP, and AC_PROG_SED.
13262 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13263 longest input length accepted by a command.
13264 (AC_PROG_SED): Use it.

13268 2004-01-27 Paul Eggert <eggert@twinsun.com>
13270 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

13294 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13295 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13296 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13297 not <inttypes.h>. Problem reported by Tim Mooney in
13298 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13299 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13302 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13303 otherwise "make check" fails because it forbids cmp (I guess
13304 because cmp treats files as binary on DOS-like systems).
13306 * tests/mktests.sh: Update copyright date to 2004, since some tests
13307 have changed in 2004.
13309 2004-01-23 Gary V. Vaughan <gary@gnu.org>

13317 2004-01-15 Paul Eggert <eggert@twinsun.com>
13319 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13320 -std1 disables some useful extensions on Tru64. Problem reported
13321 by N. Lichtmaier in
13322 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
13324 2004-01-14 Paul Eggert <eggert@twinsun.com>
13326 * doc/autoconf.texi (Programming in M4sh): Document that
13327 AS_MKDIR_P succeeds if the destination is a symbolic link
13328 to an existing directory.
13329 (Limitations of Usual Tools): Note that mkdir -p might not
13330 succeed on symlinks to directories.
13332 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13334 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13335 * bin/autoheader.in: Grammar fix in message.
13336 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13337 Test for dir before calling mkdir -p. (trivial changes)
13339 2004-01-13 Eric Blake <ebb9@byu.net>

13342 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
13344 2004-01-10 Jim Meyering <jim@meyering.net>
13346 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
13348 2004-01-09 Paul Eggert <eggert@twinsun.com>
13350 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13351 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13352 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13353 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13354 AC_COMPILE_IFELSE, since we now assume our caller invokes
13355 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13356 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13357 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13358 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13360 2004-01-07 Paul Eggert <eggert@twinsun.com>
13362 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13363 `"'...'"`, as it's confusing (and I suspect it may not work on
13364 some platforms). The code was incorrect anyway, as it assumed
13365 that \$ evaluated to itself in that context. Reported by
13366 Alexandre Duret-Lutz.
13368 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13370 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13371 and _LT_AC_TAGCONFIG.

13376 example, and add more examples. Reported by Eric Sunshine.

13398 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13399 Use "rm -f" to remove conftest.sed, not plain "rm".
13400 Bug reported by David Relson in
13401 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13403 * Makefile.am (autom4te-update):
13404 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13405 * Makefile.maint (my-distcheck, do-po-update): Likewise.

13420 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13421 -c -o might not work. From a suggestion by Kevin Ryde.
13422 (C Compiler, Generating Sources, Limitations
13423 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13424 Don't put '-o' after non-options, as POSIX doesn't allow this.
13425 Mention that cc's name might be gcc or c89 or whatever.
13427 2004-01-04 Kevin Ryde <user42@zip.com.au>
13429 * doc/autoconf.texi: Add various further index entries.

13436 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13438 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13439 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13440 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13441 explanation clearer.
13443 2003-12-24 Andreas Schwab <schwab@suse.de>
13445 * doc/autoconf.texi (Default Includes): Fix misspelling of

13451 * configure: Regenerate.
13452 * tests/atlocal.in: Store the result here.
13453 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

13455 of explicitly testing.
13456 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
13457 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13458 * tests/tools.at (Syntax of the shell scripts): Simplify

13533 the expanded body, consistently with other macros such as AC_USG.
13535 2003-11-17 Paul Eggert <eggert@twinsun.com>
13537 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

13541 2003-11-15 Kevin Ryde <user42@zip.com.au>
13543 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13544 than $target since the latter is not usual, add guidelines on when to
13545 use or not use the system type.

13695 (Parentheses): New section.
13697 2003-10-15 Kevin Ryde <user42@zip.com.au>
13699 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
13700 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
13702 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
13704 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
13707 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
13709 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
13710 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
13712 2003-10-10 Andreas Schwab <schwab@suse.de>
13714 * bin/autoheader.in: Avoid empty first line in --version and
13716 * bin/ifnames.in: Likewise.
13718 2003-10-09 Paul Eggert <eggert@twinsun.com>
13720 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
13721 Issue a more-informative diagnostic.
13722 Problems reported by Eric Sunshine.
13724 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13726 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
13727 -mGLOB_options_string stuff for Intel ifc, which can cause
13728 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
13729 pattern-matching instead of grep.
13731 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13733 * doc/autoconf.texi: Document new FC Fortran macros.
13735 2003-10-08 Gary V. Vaughan <gary@gnu.org>
13737 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
13738 that future autopoint/aclocal/automake/autoreconf will be able
13739 to trace to find where to install local m4 macros.
13740 * doc/autoconf.texi (Input): Document it.
13743 2003-10-06 Gary V. Vaughan <gary@gnu.org>
13745 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
13746 -lcrtbegin.o to list of ignored flags and fix underquoting of
13749 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
13751 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
13752 cache variable instead of $G77 to decide whether to include -O2,
13753 since $G77 is specific to Fortran 77.
13755 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13757 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
13758 free" flag. Re-order flags tested into rough order of popularity.
13760 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13762 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
13763 arguments so that it can be used with syntax identical to
13764 AC_PROG_F77, and so that we can more easily decide to
13765 remove/deprecate the DIALECT optional argument in the future if it
13766 proves troublesome.
13767 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13768 non-freeform-supporting compilers. Document freeform flags.
13770 2003-10-03 Akim Demaille <akim@epita.fr>
13772 * configure.ac: Look for emacs, not macs.
13773 Reported by Eric Sunshine.
13775 2003-10-03 Akim Demaille <akim@epita.fr>
13777 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
13778 * bin/autoreconf.in (autoreconf_current_directory): Create the
13779 AUX_DIR if needed, for sake of automake --add-missing etc.
13780 Suggested by Alexandre Duret-Lutz.
13782 2003-10-03 Akim Demaille <akim@epita.fr>
13784 * configure.ac: Quotation and formatting changes.
13785 (EMACS): Don't set it if it is not recent enough to support

13831 Problem reported by Lars J. Aas in
13832 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13833 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13834 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
13835 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
13837 2003-09-26 Akim Demaille <akim@epita.fr>
13839 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13840 directory for AC_CONFIG_COMMANDS' first argument exists.
13841 This makes valid the invocation of _AC_SRCPATH that follows.
13842 Reported by Eric Sunshine.
13843 * doc/autoconf.texi (Configuration Commands): Adjust.
13845 2003-09-26 Akim Demaille <akim@epita.fr>
13847 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
13848 Reported by Ralf Corsepius.
13850 2003-09-26 Akim Demaille <akim@epita.fr>
13852 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
13854 Actually, use AU_ALIAS.
13857 2003-09-26 Paul Eggert <eggert@twinsun.com>
13859 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
13860 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
13861 Problem reported by Eric Sunshine in:

13866 The test suite are sometimes assigning timings incorrectly.
13867 Reported by Henk Krus.
13868 Diagnosed by Nicolas Joly.
13870 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13872 Instead of making AT_help a sequence of assignments to grow
13873 $at_help_all, just make AT_help_all be the growing contents of
13874 $at_help_all, and make a single assignment in...
13876 (at_times_skip): Flip the meaning and rename as...
13877 (at_times_p): this.
13878 (AT_INIT): When summarizing the test that ran, remove
13879 $at_times_file after use, and check it is present before trying to
13882 2003-09-25 Akim Demaille <akim@epita.fr>
13886 * bin/Makefile.am (edit): Handle '@configure_input@'.
13887 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
13888 (ifnames): chmod -w.
13889 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13890 executables, not bin/ executables! Otherwise all the magic needed
13891 to find non installed files is turned off. This caused a failure
13892 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13893 as found in its environment (sent by tests/autoreconf): pointing
13894 to bin/autom4te that could not find its files.
13895 * tests/mktests.sh: Force the replacement of generated files, for
13896 the sake of "mv" program that are interactive when overwriting a
13898 * config/install-sh: Upgrade from CVS Automake.
13900 2003-09-23 Paul Eggert <eggert@twinsun.com>
13902 * doc/autoconf.texi (Limitations of Builtins): Document test -h
13903 versus test -L issues.
13905 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
13906 Paul Eggert <eggert@twinsun.com>
13908 Trivial change to support GCC's configuration procedure.
13909 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
13910 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
13911 about inconsistency if the preprocessor is set to give errors for

13944 willing to edit the output files.
13946 2003-09-10 Akim Demaille <akim@epita.fr>
13948 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
13949 and AC_FC_FREEFORM.
13950 * tests/mktests.sh: Skip AC_FC_SRCEXT.
13951 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

13987 2003-09-04 Akim Demaille <akim@epita.fr>
13989 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
13991 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13993 Add support for newer Fortran dialects. The F77 interface is
13994 unchanged, and continues to support Fortran 77. New FC macros
13995 correspond to all the old F77 macros, with output variables FC,
13996 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13997 available dialect, but older dialects can be specified. There are
13998 new macros AC_FC_SRCEXT to set the source extension, and
13999 AC_FC_FREEFORM to accept free-form source files.
14001 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
14003 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

14020 Rewrite in terms of the above.
14021 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
14022 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

14037 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
14038 are defaulted by AT_CHECK anyway.
14039 Use AT_CHECK_AUTOM4TE.
14040 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

14117 2003-08-21 Akim Demaille <akim@epita.fr>
14119 * bin/autoheader.in (&parse_args): Use &parse_warnings and
14121 ($help): Use Autom4te::ChannelDefs::usage.
14122 * bin/autoscan.in: Use Autom4te::ChannelDefs.
14123 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14125 2003-08-21 Akim Demaille <akim@epita.fr>
14127 First stab at preserving warnings between calls to autom4te,
14128 including when the cache is used.
14130 There are still several issues: (i) there are too many runs of m4
14131 (one for include, one for warnings, and some more), (ii) warnings
14132 spreading on several lines are not handled gracefully, (iii) the
14133 code meant to have the call stack display for errors does not work
14134 (its handling should move from m4 to autom4te).
14136 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14138 (@preselect): Add m4_warn.
14139 ($exit_status): Remove, use $exit_code.
14140 ($help): Use Autom4te::ChannelDefs::usage.
14141 (&handle_m4): No longer define the m4_warnings.
14142 At each run, extract and report the warnings.
14143 Always cache the result, including if the exit status is on
14144 failure, since if nothing changes, we should result in the same
14145 failure, hence we can use the cache.
14146 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14147 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14149 (m4_warn): Redefine as a do-nothing: it is its invocation that
14150 matters, as warnings are now reported via traces.
14151 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14152 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14153 the latter reveals calls to the former.
14157 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

14195 (&xsystem, &contents): Remove, since they are exported by...
14196 * lib/Autom4te/FileUtils.pm: this.

14285 -lcrt1.o, for OS X. (trivial change)
14287 2003-07-07 Paul Eggert <eggert@twinsun.com>
14289 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
14290 inside '#ifndef __cplusplus'. Problem reported by

14296 'long', not 'int', for benefit of Sun's recent C++ compilers
14297 (trivial change). See:
14298 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

14314 From Gareth McCaughan.
14316 2003-06-23 Akim Demaille <akim@epita.fr>
14318 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14319 not all of them. This fixes 1. the fact that when testing
14320 Autoconf there are many many config.log, 2. the incorrect use of
14321 top_srcdir to find config.log.
14322 Don't mix the detailed output of failed test with the summary of
14323 failures. Rather, append detailed log afterwards.
14325 2003-06-23 Akim Demaille <akim@epita.fr>
14327 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
14328 always run: output config.log on $at_group_log.

14332 * tests/torture.at (#define header templates): Don't use quotes in

14385 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
14386 (AT_INIT): Support for expected failures.
14388 2003-06-02 Akim Demaille <akim@epita.fr>

14397 2003-05-28 Paul Eggert <eggert@twinsun.com>
14399 * NEWS, doc/autoconf.texi (Particular Functions),

14401 is the inverse of localtime.

14405 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14406 (handle_exec_errors): New function. Work around $! being
14407 altered by WEXITSTATUS.
14408 (xqx, xsystem): Use handle_exec_errors.
14410 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14412 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14413 Do not call `_exit()', simply modify `$?'.
14414 (xsystem): Reset $! before running system, and check it afterward.
14415 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14416 63 for version mismatches.
14418 2003-05-23 Akim Demaille <akim@epita.fr>
14420 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14421 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14422 the middle of a line).
14423 * lib/m4sugar/m4sugar.m4: Likewise.
14424 Remove useless spaces in comments.
14426 2003-05-23 Akim Demaille <akim@epita.fr>
14428 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14429 exit 63, so that we (or Automake's "missing") can tell the
14430 difference with a plain failure.
14431 * doc/autoconf.texi (Notices): Adjust.
14433 2003-05-23 Akim Demaille <akim@epita.fr>
14435 * Makefile.am, bin/Makefile.am, config/Makefile.am,

14437 White spaces cleanup.

14440 Paul Eggert <eggert@twinsun.com>
14442 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14443 Remove `#include <stdlib.h>' from the list; we should never
14444 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14445 resulting namespace pollution would cause other tests to fail.
14446 Configure scripts run with some older versions of g++ and HP's
14447 aCC would fail due to such an #include. Problems reported by
14448 Matthew Mueller in <http://bugs.debian.org/120704> and by
14450 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14451 In the test, use the test declaration before including <stdlib.h>,
14452 as that's closer to how it'll be used.
14454 2003-05-23 Akim Demaille <akim@epita.fr>
14456 * doc/autoconf.texi (Header Portability): ucred.h.
14459 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14461 Overhaul Autotest's logging: generate separate log files
14462 in testsuite.dir/NNN/testsuite.log, and append them to
14463 testsuite.log instead of re-running the test verbosely.
14465 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14466 file descriptor, write 0 to at_status_file instead of setting
14467 at_status=0, initialize some new variables (at_status_file,
14468 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14469 to rerun the tests, instead append the at_group_log to the
14470 at_suite_log when a test fails.
14471 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14472 with the AS_MESSAGE_LOG_FD redirected to stdout.
14473 (AT_CLEANUP): save the output status in $at_status_file
14474 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14475 its original place.
14476 (AT_CHECK): since tests are run with a redirected stdout,
14477 and used to be re-run in verbose mode, turn some $at_verbose
14478 into echo, and don't redirect the output of testing stdout
14481 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14482 the name of the debugging directory and information about

14602 2003-05-06 Akim Demaille <akim@epita.fr>
14604 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14605 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14606 by aclocal.m4 is changed it might require the importing of another
14607 m4 extension file, i.e., aclocal must be run.
14609 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14610 (&parse_args): Use --force with aclocal if required and supported.
14611 (&autoreconf_current_directory): Use &run_aclocal.

14624 2003-04-29 Derek Price <derek@ximbiot.com>
14626 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14627 seperator with m4_append_uniq(). It doesn't work.
14628 (AT_CLEANUP): Add `;' to end of at_help_all.
14629 (AT_INIT): Allow --keywords to be specified more than once. When
14630 grepping $at_help_all for keywords, use the field and keyword
14631 seperators to ensure a complete keyword match. Alter at_prev handling
14632 to support the new --keywords behavior.
14634 2003-04-27 Karl Berry <karl@freefriends.org>
14636 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14637 align better with others. I also made some of the individual
14638 entries on one line, for brevity and to make it easier for me to
14639 sort my dir-example file in the Texinfo distribution :).

14706 header causes problems.
14708 2003-03-28 Akim Demaille <akim@epita.fr>
14710 * tests/torture.at (Configuring subdirectories): Require aclocal
14711 1.4, otherwise the test fails, as it does support configure.ac.

14734 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
14735 obsolete AC_HELP_STRING.
14736 (AC_HELP_STRING): AU_DEFUN to...
14737 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
14738 * tests/m4sh.at (AS_HELP_STRING): New test.

14742 2003-03-26 Derek Price <derek@ximbiot.com>
14744 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more

14785 (Automake): Automake 1.5+ no longer requires special tools to be
14786 present on the developer's host.
14788 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
14790 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
14791 to a shell that can handle redirection or quoting correctly.

14797 * bin/autoupdate.in (BEGIN): Likewise.
14798 * bin/ifnames.in (BEGIN): Likewise.
14800 * bin/ifnames.in: Add final newline to help and version messages.
14802 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
14803 to cope with DOS-style absolute paths, when constructing
14806 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
14807 When constructing paths with IFS=:, quote the path. If we're
14808 constructing a DOS-style absolute path, we don't want to split it
14811 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14814 2003-02-25 Pavel Roskin <proski@gnu.org>

14822 2002-09-01 patch by replacing "test -n" with "test -z".
14823 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
14824 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
14826 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
14827 to fix a mismatch between example and discussion.

14831 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14832 format starting with "-".
14834 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14836 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14837 is not portable inside Makefile.
14839 2003-02-20 Akim Demaille <akim@epita.fr>
14841 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14842 compiler says yeah, but preproc says nope, compiler is right.
14843 Conversely, prompt the reader to send a bug report to the
14844 maintainers of the package, not of Autoconf.
14846 2003-02-20 Klee Dienes <kdienes@apple.com>
14848 * bin/autoreconf.in (autoreconf_current_directory): Properly
14849 handle an empty aclocal.m4.

14854 $ac_prefix_program.
14857 2002-12-23 Paul Eggert <eggert@twinsun.com>
14859 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14860 innocuous variant befor including <limits.h> or <assert.h>. This
14861 works around a bug reported by Albert Chin: HP-UX 11i
14862 (and earlier versions) have a <limits.h> that declares
14863 gettimeofday and many other functions.
14865 2002-12-03 Paul Eggert <eggert@twinsun.com>
14869 * NEWS, configure.ac: Update version.
14871 * doc/fdl.texi: Upgrade to FDL version 1.2.
14873 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14874 nontrivially in main's body, so that f's external declaration is
14875 not optimized away in AIX. This should fix the bug reported by
14877 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14879 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14880 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14881 defined, to support freestanding compilers. This should fix the
14882 bug reported by Momchil Velkov in
14883 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14885 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14886 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
14887 obsolete AC_CHECK_TYPE. The missing empty arg was reported

14889 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
14891 * Makefile.maint (www-gnu): New macro.
14892 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

14917 Update from masters.
14919 2002-11-14 Akim Demaille <akim@epita.fr>
14921 * Makefile.maint: Sync with Bison, i.e.:
14922 (po-check): Scan .l and .y files instead of the
14923 .c and the .h files that they generate. This fixes the bug
14924 reported by Tim Van Holder in:
14925 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14926 Look for N_ as well as for _. Try to avoid matching #define for
14930 2002-11-14 Akim Demaille <akim@epita.fr>
14932 * doc/autoconf.texi (C Compiler): Compiling several files at once.
14933 From Paul Eggert and Albert Chin-A-Young.
14935 2002-11-14 Akim Demaille <akim@epita.fr>
14937 * doc/autoconf.texi (C Compiler): Solitary backslashes.
14938 From Paul Eggert and Albert Chin-A-Young.
14940 2002-11-14 Kevin Ryde <user42@zip.com.au>
14942 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14943 than assigning in main, to avoid HP cc +O3 optimizing it away.
14945 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
14947 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14948 option. Process --recheck after parsing all options. Pass -q
14949 option to configure on --recheck.
14950 (AC_OUTPUT): Pass -q from configure to config.status.
14951 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
14952 arguments to record.
14953 * doc/autoconf.texi (config.status Invocation): Document
14954 config.status -q option.
14956 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
14958 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
14959 Makefile.in if Makefile.am exists.
14960 (output): Strip `.am' from Makefiles. Don't
14961 output AC_CONFIG_FILES if no Makefiles were found.

14981 Reported by Ezra Peisach.
14983 2002-11-05 Akim Demaille <akim@epita.fr>
14985 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14987 We _have_ to stop using the old compatibility scheme that tried to
14988 avoid useless backslashes because Libtool 1.4.3 contains a
14989 AC_DEFINE([error_t], [int],
14990 [Define to a type to use for \`error_t' if it is not
14991 otherwise available.])
14992 We _have_ to quote the single quote and backslashes with \. The
14993 old compatibility scheme saw that ` was backslashed, and therefore
14994 did not quote the single quote. Hence before this patch, Autoconf
14995 was not compatible with Libtool.
14997 2002-11-04 Paul Eggert <eggert@twinsun.com>
14999 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15014 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
15016 (&autoreconf): here.
15017 ($help, $make, &parse_args, &autoreconf_current_directory):
15019 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15021 2002-10-31 Bruno Haible <bruno@clisp.org>

15037 2002-10-31 Akim Demaille <akim@epita.fr>
15039 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
15040 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15041 Make variable, not a shell variable.
15042 Suggested by Bruno Haible.
15044 2002-10-31 Akim Demaille <akim@epita.fr>
15046 * bin/autom4te.in (load_configuration): Reject #args out of any
15049 2002-10-31 Akim Demaille <akim@epita.fr>
15051 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
15052 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
15053 (_AC_RUN_IFELSE): Use it.
15054 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

15063 Suggested by Tim van Holder.
15065 2002-10-29 Paul Eggert <eggert@twinsun.com>
15067 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
15068 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
15069 Problem reported by Bruno Haible.
15071 2002-10-29 Akim Demaille <akim@epita.fr>
15073 * doc/autoconf.texi (Header Templates): Put also in words what the
15074 pictures says to assist free style readers.
15075 (Customizing autom4te): s/--cache=/--cache /.
15077 2002-10-29 Akim Demaille <akim@epita.fr>
15079 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
15081 sparc_address_test returns void.
15082 Use it with an argument, as prototyped.
15085 2002-10-29 Akim Demaille <akim@epita.fr>
15087 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

15449 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15450 aclocal invocation, as Gettext macros might not be visible to

15657 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15658 (chdir_init) might hang when stat'ing mounted directories.
15659 Reported by Vance Shipley.
15661 2002-09-12 Akim Demaille <akim@epita.fr>
15663 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15666 2002-09-12 Akim Demaille <akim@epita.fr>
15668 * doc/autoconf.texi (Defining Symbols): Present two different
15669 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15670 difference between 1 argument calls, and 2-3 argument calls.
15672 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15674 * doc/autoconf.texi: Review grammar and punctuation.
15676 2002-09-11 Paul Eggert <eggert@twinsun.com>
15678 * doc/autoconf.texi: Fix minor formatting, spelling, and
15680 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15681 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15684 2002-09-11 Akim Demaille <akim@epita.fr>
15686 * doc/autoconf.texi (Questions): Rename as...
15688 (Defining Directories): New.
15690 2002-09-09 Akim Demaille <akim@epita.fr>
15692 * doc/autoconf.texi (Making testsuite Scripts): Update.
15693 Suggested by Nishio Futoshi.
15695 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15697 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15698 plain `@' is wanted.
15700 2002-09-09 Akim Demaille <akim@epita.fr>
15702 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15703 `duplicates', since the algorithm was too naive and could keep
15704 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15705 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15706 Reported by Ralf Corsepius.
15707 * tests/torture.at (Configuring subdirectories): Exercise these
15710 2002-09-09 Akim Demaille <akim@epita.fr>
15712 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15713 looking for a replacement file.
15714 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15715 directory is relative.
15716 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15717 directory definition.
15718 Reported by Andreas Schwab and Jim Meyering.
15720 2002-09-06 Akim Demaille <akim@epita.fr>
15722 * doc/autoconf.texi (Setting Output Variables): Clarify what
15723 precious variables are.
15724 Suggested by Pontus Skoeld.
15726 2002-09-05 Akim Demaille <akim@epita.fr>
15728 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15729 (ifnames, autoscan, autom4te): Since we don't only depend on
15730 configure.ac variables (such as VERSION etc.), but also on prefix
15731 and so forth, depend on Makefile, not configure.ac.
15732 Reported by Alexandre Duret-Lutz.
15733 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15735 2002-09-05 Kevin Ryde <user42@zip.com.au>
15737 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15738 doesn't seem to be confined to ia64, just say "some versions".
15740 2002-09-04 Akim Demaille <akim@epita.fr>
15742 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15744 * Makefile.am (maintainer-clean-local): Remove.
15745 (MAINTAINERCLEANFILES): Remove COPYING.
15747 2002-09-03 Paul Eggert <eggert@twinsun.com>
15749 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15750 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15753 2002-09-03 Akim Demaille <akim@epita.fr>
15755 * configure.ac: Bump to 2.53d.
15756 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15757 as of today, on Automake's team suggestion.
15759 2002-09-03 Akim Demaille <akim@epita.fr>
15763 2002-09-02 Akim Demaille <akim@epita.fr>
15765 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15767 * configure.ac: Disable SITE_MACRO_DIR.
15769 2002-09-02 Jim Meyering <meyering@lucent.com>
15771 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15772 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15773 Also, tweak grammar: s/make sure to/be sure to/.
15775 2002-09-02 Paul Eggert <eggert@twinsun.com>
15777 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15778 directory names are generally preferable to physical names.
15780 2002-09-02 Akim Demaille <akim@epita.fr>
15782 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15783 Reported by Raja R. Harinath.
15784 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15785 * bin/autoupdate.in: Use error instead of die.
15787 2002-09-01 Paul Eggert <eggert@twinsun.com>
15789 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15790 ordinary shell concatenation rather than echo+tr+sed command that
15791 runs afoul of a long-line-related sed bug in Solaris 8.
15793 * bin/autoheader.in (parse_args): --warning -> --warnings.
15795 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15796 stdout, as traditional "ls" does.
15797 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15798 _AC_COMPILER_EXEEXT_O): Likewise.
15799 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15801 * bin/autoconf.as: Add --prepend-include option. This patch was
15802 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15803 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15805 * bin/autoconf.in, configure: Regenerate.
15807 * doc/autoconf.texi (Special Shell Variables): Mention
15808 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15810 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15811 MAILPATH and set PS1, PS2, PS4 to default values, to work
15812 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15813 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15814 the Autoconf documentation specifies; fall back to "unset" only if
15815 this fails. Use a shell for-loop for this rather than an m4 loop,
15816 to shorten the output script.
15818 2002-08-30 Paul Eggert <eggert@twinsun.com>
15820 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15821 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15822 for the CDPATH problem. Document PWD.
15823 (Limitations of Builtins): Document the problem that "cd $foo" and
15824 "ls $foo" may refer to different directories in shells conforming
15825 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15826 example, since the old example is now out of date.
15828 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15829 FOO" and "ls FOO" talk about different directories; this catches
15830 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15833 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15834 of rolling our own unset.
15835 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15836 in practice we needn't worry about CDPATH if unset doesn't work.
15838 * Makefile.in, aclocal.m4, bin/Makefile.in,
15839 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15840 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

15842 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15843 tests/Makefile.in: Regenerate with Automake 1.6.3.
15845 * config/config.guess, config/config.sub, config/mkinstalldirs:
15848 * configure: Regenerate with self.
15850 2002-08-30 Kevin Ryde <user42@zip.com.au>

15860 2002-08-29 Akim Demaille <akim@epita.fr>
15862 * lib/Autom4te/General.pm (&xqx): New.
15863 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15864 hand, which is not portable.
15866 * bin/autom4te.in: Use them.
15867 Use &error instead of die.
15868 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15871 2002-08-17 Paul Eggert <eggert@twinsun.com>
15873 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15874 default list of compilers to try, since it was long ago superseded
15875 by the ksh fc builtin. Suggested by Steven G. Johnson.
15877 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15879 * doc/autoconf.texi (Invoking autom4te): End the option table,
15880 fixing a bug introduced by the previous patch.
15881 (Limitations of Make): Add a 'target lookup' subentry in the
15882 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15884 2002-07-29 Mark D. Roth <roth@feep.net>
15886 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15887 options and use $AUTOM4TE_PATH.
15888 * doc/autoconf.texi: Remove documentation of autom4te
15889 --include-envvar and --site-macro-subdir options and document
15890 use of $AUTOM4TE_PATH.
15891 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15892 arguments from each language section.
15894 2002-07-29 Paul Eggert <eggert@twinsun.com>
15896 * doc/install.texi: Include copyright symbol in copyright notice.
15898 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15900 (AM_MAKEINFOFLAGS): New macro.
15901 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15902 * Makefile.am (INSTALL): Use the new macros.
15903 Use -o rather than --output, since "missing" does not grok --output.
15905 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15907 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15908 comments do not always work. Never trust the exit status of
15911 2002-07-24 Kevin Ryde <user42@zip.com.au>
15913 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15914 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15916 2002-07-23 Paul Eggert <eggert@twinsun.com>
15918 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15919 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15920 apparently treats PATH="nonexistent" as if it contained ".".
15921 Bug reported by Stefan `Sec' Zehl.
15923 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15925 * doc/autoconf.texi (Limitations of Make): Mention the special

15973 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
15974 latter was not run.

16144 * config/config.guess, config/config.sub, config/texinfo.tex:
16145 Update from masters.
16147 2002-05-29 Paul Eggert <eggert@twinsun.com>

16167 2002-05-27 Paul Eggert <eggert@twinsun.com>
16169 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
16170 * NEWS, doc/autoconf.texi (Particular Types): Document it.
16171 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
16172 instead of AC_MBSTATE_T, which never existed.

16176 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
16177 version of Autoconf that is discussed.
16179 2002-05-22 Paul Eggert <eggert@twinsun.com>
16181 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
16182 from the default list of compilers to try. Suggested by
16184 * NEWS: Document the above.
16185 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
16187 2002-05-17 Paul Eggert <eggert@twinsun.com>
16189 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
16190 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
16191 This improves on an earlier suggestion by H. Peter Anvin.
16193 2002-05-16 Paul Eggert <eggert@twinsun.com>
16195 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16196 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16197 Both macros now accept an optional source-dir arg.
16198 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16200 * NEWS: Document this.
16201 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16203 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16204 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16205 not for GNU extensions; this undoes part of the 2000-11-03 change,
16206 reverting to 2.13-compatible behavior.
16207 Add new optional argument DIR.
16208 (AC_FUNC_FNMATCH_GNU): New macro.
16210 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
16212 2002-05-08 Paul Eggert <eggert@twinsun.com>
16214 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16215 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16216 and it causes a 'test' syntax error if it fails.
16217 Bug reported by Stephen Gildea.
16219 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16220 If prototypes are supported, use them to check this at compile-time,
16221 instead of trying to check it at run-time. If we must do a run-time
16222 check, assume that setvbuf is standard when cross-compiling, as
16223 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16224 Bug reported by Paul D. Smith.
16226 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16227 argument specifying location of getloadavg.c. This removes a
16228 FIXME. This idea was taken from Jim Meyering's implementation in
16230 * doc/autoconf.texi (Particular Functions): Document this.
16231 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16232 that's what the code does; this fixes a bug reported by
16235 2002-05-03 Akim Demaille <akim@epita.fr>
16237 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16238 autopoint instead of gettextize.
16239 ($uses_alocal): Rename as...
16240 ($uses_aclocal): this.
16241 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16242 Suggested by Bruno Haible.
16244 2002-05-03 Akim Demaille <akim@epita.fr>
16246 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16248 2002-04-29 Paul Eggert <eggert@twinsun.com>
16250 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16251 files to be 1 second older; just set them to be the same time.
16252 Also, sleep 1 second after the first aclocal, to work around
16253 problems with sub-second time stamps on the input files.
16255 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16257 * doc/autoconf.texi: Mention "set -e -x" lossage
16258 under node "Limitations of Builtins".
16260 2002-04-29 Akim Demaille <akim@epita.fr>
16262 * doc/install.texi: Better wording for setting variables when
16264 From Christian Cornelssen.
16266 2002-04-29 Akim Demaille <akim@epita.fr>
16268 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16269 of lack of $LINENO support, then the test will compare the $LINENO
16270 in testsuite vs. the lineno in the test file. This is wrong, of
16272 Be sure to protect it.
16273 Reported by Patrick Welche.
16275 2002-04-25 Akim Demaille <akim@epita.fr>
16277 * doc/autoconf.texi (Obsolete Macros): Typo.
16278 Reported by Vladimir Volovich.
16280 2002-04-25 Akim Demaille <akim@epita.fr>
16282 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16283 than some of the input files, hence, on the second run of aclocal,
16284 if some of its input are younger, make them older.
16285 Suggested by Paul Eggert.
16287 2002-04-25 Akim Demaille <akim@epita.fr>
16289 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16294 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
16295 and ac_subst_vars be sh variables containing the list of
16296 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
16298 (_AC_INIT_PREPARE): Use them to log them.
16299 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16300 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16301 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16302 _AC_SUBST_FILES and _AC_SUBST_VARS.
16303 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16305 2002-04-24 Akim Demaille <akim@epita.fr>
16307 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16308 autoheader, so that automake does not complain about a missing
16309 config.h.in that was to be created.
16311 2002-04-23 Akim Demaille <akim@epita.fr>
16313 * bin/autoheader.in (parse_args): --warning takes an argument.
16316 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
16318 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

16363 Minor spelling and grammar fixes.
16365 * doc/autoconf.texi: Follow the outline suggested in the GNU
16366 Sample Texts sections of the Texinfo 4.2 manual. Most
16367 importantly, this makes sure that the copyright notices appear in
16368 all output formats. You probably need Texinfo 4.2 to generate

16397 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

16407 workaround for ${1+"$@"}.
16408 * doc/autoconf.texi (Shell Substitutions): Explain it.
16409 From Oliver Kiddle and Peter Stephenson.
16411 Have M4sh perform minimal shell sanitizing.
16413 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
16415 (_AS_PREPARE): this new macro.
16417 (AS_INIT): Invoke AS_SHELL_SANITIZE.

16420 Adjust Autoconf and Autotest.
16422 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
16423 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
16424 * lib/autotest/general.m4 (AT_INIT): Likewise.
16425 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
16426 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
16429 Use this M4sh to generate Autoconf's shell scripts.
16431 * tests/wrapsh.as: New, precursor of wrapsh.in.
16432 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
16433 on Autotest and M4sh.
16434 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
16435 (wrapsh.in): New target.

16451 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
16452 (Portable Shell): Cross reference to Systemology.
16454 2002-04-05 Akim Demaille <akim@epita.fr>
16456 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
16457 directories when descending in a SUBDIRS.

16460 2002-04-04 Andreas Schwab <schwab@suse.de>

16469 Use dnl, not the KILL diversion.
16471 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
16472 (AC_CONFIG_LINKS): here.
16474 Don't use the KILL diversion, as it kills spurious output, which
16475 results in failures being hidden.
16476 Use m4_defn where appropriate.
16477 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
16478 after the second argument.
16480 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
16481 syntax, as it is provided by M4sugar.

16526 2002-03-27 Paul Eggert <eggert@twinsun.com>
16528 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

16542 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
16543 as POSIX requires, as it doesn't work with Zsh.

16546 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16548 * doc/autoconf.texi (Limitations of Make): Mention more issue
16549 about VPATH, overriding of macros in sub-makes, and handling of
16552 2002-03-21 Paul Eggert <eggert@twinsun.com>
16554 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16555 problem with here-document buffer boundaries.
16557 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16558 when reinvoking the shell, to work around problems with installers
16559 who put strange things like "cd" commands in their environments.

16583 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16584 (Limitations of Usual Tools): Add mkdir section.
16586 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16587 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16588 back on AS_DIRNAME to compute prefixes otherwise; this is
16589 roughly what mkinstalldirs does. That way, we need not have
16590 our own filename disassembler. The old disassembler did not
16591 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16593 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16594 Create at_test_all by a series of assignments,
16595 not by a single assignment of a long string. The latter causes ksh
16596 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16597 presumably because of a buffer overrun.
16599 2002-03-14 Paul Eggert <eggert@twinsun.com>
16601 * lib/autotest/general.m4 (at_times_skip):
16602 Renamed from at_times. Now a boolean.
16603 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16604 says 'times: not found'.

16698 (Hosts and Cross-Compilation): this new section.
16699 * doc/install.texi (System Type): Ditto.
16700 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

16713 2002-03-04 Akim Demaille <akim@epita.fr>

16718 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16719 $*. This is the n-th time I change my mind, but hopefully this is
16722 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16724 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16725 it was only a hack for m4_text_wrap.
16726 (m4_car2): Remove, replaced by...
16728 (_m4_foreach): Adjust.
16729 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

16891 AUTOTEST_PATH *after* it was set.
16892 Don't put `.' in the PATH: the user should be precise and `./' if
16893 needed. In addition, given that the test suite does some `cd', if
16894 `.' is in the path, the `tested programs' sections will report
16895 programs found in the test suite's directory, while during the
16896 tests (performed in their own directory), these programs are no
16897 longer visible. In other words, the results is confusing and

16974 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16975 and PACKAGE_BUGREPORT from here...
16976 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16978 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

17123 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17124 static, to catch errors if the value isn't known at compile-time
17125 and the compiler supports dynamic arrays. Change its name from
17126 `_array_' to `test_array' to avoid potential name clashes.
17127 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17128 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17129 better than double. Catch a bug in GCC 2.95.2 x86.

17139 2001-11-13 Akim Demaille <akim@epita.fr>
17141 * lib/autotest/general.m4 (AT_INIT): After having run the test
17142 group, go back to the initial directory, not to at_suite_dir.
17144 2001-11-13 Akim Demaille <akim@epita.fr>
17146 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17147 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17148 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17150 (AT_CHECK_CONFIGURE): Use absolute paths.
17151 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17152 The problem is still the old one: there is no means in M4 (that I
17153 know about) to create a defining macro, because there is no means
17154 to create `$1' etc., therefore, the defining macro ``swallows''
17155 all the arguments meant to the defined macro.
17157 2001-11-13 Akim Demaille <akim@epita.fr>
17159 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17160 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17162 * tests/aclocal.m4: Remove, as it is no longer used.
17164 2001-11-13 Akim Demaille <akim@epita.fr>
17166 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17167 variable names when referring to a single test group, or to
17168 `suite' when referring to the whole test suite.
17169 `at_last_test' is removed: m4 compute at_format itself.
17170 (at_stdout, at_stder1, at_stderr): New variables.
17171 (AT_CHECK): Use them.
17173 2001-11-13 Akim Demaille <akim@epita.fr>
17175 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17177 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17178 Do it as soon as a test fails, don't wait till the end of the test
17180 Don't remove $as_me.[0-9]*, since these files no longer exist.
17182 2001-11-13 Akim Demaille <akim@epita.fr>
17184 * tests/tools.at: Use absolute paths, since we are no longer run
17187 2001-11-13 Akim Demaille <akim@epita.fr>
17189 Now that tests are running in their own private dir, there is no
17190 need to list the files to remove at the end of tests groups.
17192 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17193 (AT_data_files, at_data_files): Remove.
17194 (AT_CLEANUP, AT_DATA): Simplify.
17196 Remove the group dir if !debug && !failed.
17197 * tests/atspecific.m4: Adjust.
17199 2001-11-13 Akim Demaille <akim@epita.fr>
17201 Start a new layout for Autotest: `testsuite' creates
17202 `testsuite.dir' in which the at-check-line etc. files are to be
17203 found, and `testsuite.dir/003' where the test group 3 is run.
17205 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17206 at_check_line_file, at_format, at_test_normalized, at_group_dir
17208 Create the directories.
17209 Use absolute paths for at- files.
17210 (AT_CHECK): Adjust.
17212 2001-11-11 Michael Matz <matz@kde.org>
17214 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17216 (m4_car): Properly quote arguments.
17218 2001-11-13 Akim Demaille <akim@epita.fr>
17220 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17221 with stricter rules on LIBOBJS.
17223 2001-11-12 Paul Eggert <eggert@twinsun.com>
17225 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17226 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17229 2001-11-12 Akim Demaille <akim@epita.fr>
17231 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17233 2001-11-12 Akim Demaille <akim@epita.fr>
17235 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17236 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17237 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17238 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17239 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17240 specify to what the macro should be defined (typically to 1).
17242 2001-11-12 Akim Demaille <akim@epita.fr>
17244 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17247 2001-11-12 Akim Demaille <akim@epita.fr>
17249 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17250 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17251 definition used by Automake where LEX is +/- "${missing} lex" and
17252 `missing' itself contains variables.
17254 2001-11-12 Akim Demaille <akim@epita.fr>
17256 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17257 Now that M4sh pushes BODY, the comments were output at the end of
17260 2001-11-08 Akim Demaille <akim@epita.fr>
17262 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17263 that we can trace macros from aclocal.m4.
17264 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17265 obsoleted, and redirect to the former anyway.
17266 Reported by Ralf Corsepius.
17268 2001-11-08 Akim Demaille <akim@epita.fr>
17270 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17271 processed only if present.
17272 * tests/torture.at (Configuring subdirectories): Use autoreconf
17273 instead of successive calls to autoconf.
17274 Add a nonexistent subdirectory to exercise the patch above.
17275 Reported by Ralf Corsepius.
17277 2001-11-08 Kevin Ryde <user42@zip.com.au>
17279 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17280 doesn't accept .S files.
17282 2001-11-07 Akim Demaille <akim@epita.fr>
17284 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
17285 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
17286 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
17287 * bin/autom4te.in (warn_forbidden): New.
17288 (handle_output): Use it.
17289 Read m4_pattern_forbid with messages.
17291 2001-11-05 Akim Demaille <akim@epita.fr>
17293 * bin/autom4te.in (--normalize): Remove.
17294 * lib/autom4te.in: Adjust.
17296 2001-11-05 Akim Demaille <akim@epita.fr>
17298 * tests/Makefile.am (testsuite): Rename this target as...
17299 ($(TESTSUITE)): this.
17302 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17304 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17305 the --prefix option, also remove it's argument.
17307 2001-11-05 Akim Demaille <akim@epita.fr>
17309 * doc/autoconf.texi (testsuite Invocation): Update.
17310 (Writing testsuite.at): Update.
17312 2001-11-03 Akim Demaille <akim@epita.fr>
17314 * doc/autoconf.texi: s/@code/@command/ where appropriate.
17316 2001-11-03 Akim Demaille <akim@epita.fr>
17318 * lib/Autom4te/General.pm: (&catfile, &canonfile)
17319 (&file_name_is_absolute): New, wrappers around routines from
17321 Use and export them.
17322 (&find_configure_ac): Optionally take a directory where to look at.
17323 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17325 Default @ARGV to `.', not find_configure_ac.
17326 (&autoreconf): Argument is a directory.
17327 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17328 * doc/autoconf.texi (autoreconf Invocation): Update.
17330 2001-11-03 Akim Demaille <akim@epita.fr>
17332 * lib/Autom4te/General.pm (@export_vars, @export_subs)
17333 (@export_forward_subs): New.
17334 Add basename, dirname, and fileparse.
17336 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
17337 Don't look for aclocal flags if we already know aclocal is not
17339 Move aclocal.m4t only if it exists.
17340 Reported by Ezra Peisach.
17342 2001-11-03 Akim Demaille <akim@epita.fr>
17344 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17345 passed on command line, defaulting to ./configure.ac if present.
17346 (&maybe_autoreconf, File::Find): Remove, unused.
17347 (&autoreconf): If autoconf is not used, don't try to trace.
17349 2001-11-02 Akim Demaille <akim@epita.fr>
17351 * configure.ac: Bump to 2.52g.
17353 2001-11-02 Akim Demaille <akim@epita.fr>
17357 2001-11-02 Akim Demaille <akim@epita.fr>
17359 * config/config.guess, config/config.sub, doc/standards.texi:
17360 * config/lispdir.m4: Update from masters.
17361 * configure.ac: Bump to 2.52f.
17363 2001-11-02 Akim Demaille <akim@epita.fr>
17365 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17366 Don't run aclocal when aclocal.m4 is not from aclocal.
17368 Don't run libtoolize and gettextize if --install is not given.
17370 2001-11-01 Paul Eggert <eggert@twinsun.com>
17372 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17373 be invoked before _AS_LINENO_PREPARE.
17374 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17375 than character ranges.
17377 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17378 invoking AS_BASENAME. Set the locale variables to 'C' if
17379 possible, as POSIX requires this to get the traditional
17381 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17383 2001-10-31 Paul Eggert <eggert@twinsun.com>
17385 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17386 with {}, as that triggers a bug in Bash 2.05.
17388 (_AS_LINENO_PREPARE): Use Sed rather than
17389 Awk. Fix the sed prepass to work even if there are multiple
17390 instances of $LINENO on the same line. Do not substitute for
17391 other variables like $LINENOT. Do not check file dates; such a
17392 check is unreliable on sufficiently fast machines, and removing
17393 the check makes the code simpler and more reliable. Check for
17394 output and chmod failures.
17396 * doc/autoconf.texi (Special Shell Variables): Document
17399 2001-10-31 Akim Demaille <akim@epita.fr>
17401 * tests/Makefile.am (atconfig): Remove this target, Automake
17404 2001-10-31 Akim Demaille <akim@epita.fr>
17406 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17407 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17408 provided, while it is optional.
17409 * configure.ac: Adjust.
17411 2001-10-26 Paul Eggert <eggert@twinsun.com>
17413 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17414 lib/Autom4te/Struct.pm:
17415 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17418 * doc/autoconf.texi (Special Shell Variables): Document some
17419 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17421 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17422 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17423 eval $LINENO is not portable in practice.
17425 2001-10-24 Akim Demaille <akim@epita.fr>
17427 * lib/Autom4te/General.pm (backname): New.
17429 2001-10-24 Akim Demaille <akim@epita.fr>
17431 * m4/: Remove, merged into...
17434 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
17436 * doc/autoconf.texi (Shellology): Mention the problems with bash
17437 2.05's use of ANSI quoting in its `set' builtin.
17439 2001-10-22 Paul Eggert <eggert@twinsun.com>
17441 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17442 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17443 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17444 POSIX decided to standardize on the int flavor of strerror_r.
17445 Always do char* test, as there's no reason not to.
17446 Assign to a char* var, to catch strerror_r that returns int*.
17448 * doc/autoconf.texi (Particular Functions):
17449 Document the above changes. Also, document the fact that
17450 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17452 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17454 2001-10-20 Akim Demaille <akim@epita.fr>
17456 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
17457 the executable was missing from the log.
17459 2001-10-20 Akim Demaille <akim@epita.fr>
17461 * lib/Autom4te/General.pm (&update_file): If destination is
17462 unchanged, remove the source.
17463 (&up_to_date_p): Don't be verbose, be debug.
17464 * bin/autoreconf.in: No longer support --m4dir.
17465 (&autoreconf): Display the full path of the configure.ac we are
17467 Trace it only once.
17468 Be sure to honor --force with gettextize.
17469 Always run aclocal.
17470 * doc/autoconf.texi: Adjust.
17472 2001-10-20 Akim Demaille <akim@epita.fr>
17474 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17476 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17477 `intl' is already present, as it refuses unless --force.
17478 (&parse_args): Use -I, --include instead of the old Autoconf
17480 ($localdir, $autoconf_dir): Remove.
17482 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17484 2001-10-19 Jens Petersen <petersen@redhat.com>
17486 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17493 Don't mention `automatically' in addition to `generated'.
17494 * tests/torture.at (#define header templates): Adjust.
17496 2001-10-19 Akim Demaille <akim@epita.fr>
17498 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a

17502 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17504 * bin/autoreconf.in (autoreconf): Display the path to the
17505 configure.ac being studied.
17507 2001-10-18 Paul Eggert <eggert@twinsun.com>
17509 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17510 long, to work around a bug in the HP C compiler version HP92453-01
17513 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17514 (AS_BASENAME_EXPR): New macro.
17515 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17516 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17517 and fall back on 'sed' only if the other two fail. This makes
17518 AS_BASENAME act more like AS_DIRNAME.
17519 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17520 contains white space.
17521 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17522 Use AS_DIRNAME, since I think it's now DOS-friendly.
17523 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
17524 Allow "dirname //FOO" to return either / or //, as POSIX allows
17527 2001-10-10 Akim Demaille <akim@epita.fr>
17529 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

17533 2001-10-10 Akim Demaille <akim@epita.fr>
17535 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
17536 m4_define, since...
17537 (_AS_ECHO_N): AS_REQUIREs it.
17539 2001-10-10 Akim Demaille <akim@epita.fr>
17541 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

17628 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
17630 2001-10-08 Akim Demaille <akim@epita.fr>
17632 Use `add-log-current-defun-function' for ChangeLog creation.
17633 Suggested by Tom Tromey.
17635 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
17636 (autotest-mode): Adjust.
17637 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

17664 shell does not support LINENO, and if CONFIG_SHELL is unset or
17665 empty, and if we can find a shell that does support LINENO,
17666 then set CONFIG_SHELL to that shell and then re-execute
17667 ourselves with CONFIG_SHELL.
17669 2001-10-05 Paul Eggert <eggert@twinsun.com>
17671 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
17672 doesn't exist. Remove *.tmp, as a .tmp file is created during the
17673 build of $(TESTSUITE).
17675 2001-10-05 Akim Demaille <akim@epita.fr>

17714 compatibility with POSIX shells.

17742 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
17743 Don't use nested parenthesization. This patch was originally

17745 but somehow it didn't get incorporated then.
17746 * doc/autoconf.texi (Limitations of Usual Tools):

17752 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17753 Check for `expr' arithmetic overflow, and for compilation failure,
17754 and invoke a new argument $4 if either is discovered.
17755 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
17756 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
17758 2001-09-28 Akim Demaille <akim@epita.fr>

17789 (AC_PROG_CPP requires AC_PROG_CC): here and...
17790 * tests/fortran.at (GNU Fortran 77): there.
17791 * doc/autoconf.texi (autoconf Invocation): Fix the example:
17792 AC_TRY_RUN is about compilation, not shell commands.

17820 2001-09-23 Akim Demaille <akim@epita.fr>
17822 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
17823 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

17834 * lib/autotest/general.m4: Do not reset AT_victims.
17835 Don't compute at_srcdir nor at_top_srcdir.
17837 * tests/tools.at: Hence use top_srcdir.
17839 * tests/Makefile.am, tests/autoconf, tests/autoheader,
17840 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
17842 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,

17894 2001-09-22 Akim Demaille <akim@epita.fr>
17896 * lib/autoconf/autotest.m4: Create `package.m4'.
17897 * tests/Makefile.am (package.m4): Remove.
17899 2001-09-22 Akim Demaille <akim@epita.fr>
17901 Rely on `$LINENO' when possible instead of `__oline__'.
17903 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
17904 `$LINENO' support replacement when not supported.
17905 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
17906 them explicitly to be sure they are not output before this section
17907 (via m4_require). Cosmetic only.

17909 * lib/autoconf/programs.m4: Replace all the occurrences of
17910 `__oline__' with `$LINENO'.
17911 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
17913 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
17915 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
17916 character (u: -> ue) in a code comment.
17917 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
17920 2001-09-21 Akim Demaille <akim@epita.fr>
17922 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
17923 Suggested by Jim Meyering.
17925 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17927 * lib/autoconf/programs.m4: Use extensions listed in
17928 $ac_executable_extensions when looking for programs.
17930 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17932 * lib/autoconf/general.m4: Fix a small Englisho.

17935 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
17937 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

17941 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
17942 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
17943 be used instead of ':'.
17944 * lib/autotest/general.m4: Replace occurrences of ':' in
17945 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
17947 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17949 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
17950 arguments. Fixed a typo.
17952 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17954 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
17955 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
17957 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17959 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
17960 * bin/autoupdate.in: Ditto.
17961 * bin/autoheader.in: Reworded a few comments.
17962 * bin/autoconf.in: Reworded help text for a few options.

17966 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17968 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
17969 already have $file). Set output files to binary mode (helps avoid
17970 CR issues on DOSish systems).
17972 2001-09-19 Akim Demaille <akim@epita.fr>
17974 * lib/autotest/general.m4: Englishoes.
17975 From Tim Van Holder and Alexey Mahotkin.
17977 2001-09-18 Paul Eggert <eggert@twinsun.com>
17979 * doc/autoconf.texi (Common Shell Constructs): New node,
17980 documenting AS_DIRNAME.
17981 (Limitations of Usual Tools): Refer to it when discussing dirname.
17982 Also, update discussion of POSIX standard to reflect latest draft.
17984 * lib/autoconf/c.m4:
17985 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17987 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17988 Do not pass a first argument with leading '-'
17989 to expr, by parenthesizing initial integers that might be negative.
17991 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17992 now merely checks whether it is an error to pass an argument
17995 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17996 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17997 whether it is a (compile-time) error to pass an argument to
17998 getpgrp. This simpler test supports the revised documentation,
17999 and is all that AC_FUNC_GETPGRP's users really need.
18001 2001-09-18 Akim Demaille <akim@epita.fr>
18003 * doc/autoconf.texi (Limitations of Make) <$<>: New.
18005 2001-09-18 Akim Demaille <akim@epita.fr>
18007 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
18009 * lib/autotest/general.m4 (AT_INIT): Adjust.
18011 2001-09-18 Paul Wagland <paul@wagland.net>
18013 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18015 Add test for AS_BASENAME.
18016 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18017 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18018 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18019 * tests/base.at: Fixed the expected responses. The old ones were
18021 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18022 the documentation claims it should (and how it behaved in 2.13).
18024 2001-09-18 Akim Demaille <akim@epita.fr>
18026 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18027 the AC_CONFIG_COMMANDS invocation.
18028 This also solves the name clash problems.
18029 Don't set the package's ID.
18030 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18031 No longer to be shipped.
18032 (version.in): Remove.
18033 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18034 * lib/autoconf/status.m4: Adjust.
18035 Use `m4_PACKAGE_STRING'.
18036 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18037 the only optional argument is the name of the test suite.
18038 Expect `package.m4' to define the package signature.
18039 * lib/autom4te.in (Autotest): Add `package.m4?'.
18040 * tests/Makefile.am (package.m4): New.
18041 * tests/suite.at: ifnames is a victim.
18043 2001-09-18 Akim Demaille <akim@epita.fr>
18045 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18046 AC_LIBSOURCE, AC_CONFIG_FILES.
18047 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18048 program version string doesn't match the package's.
18049 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
18052 2001-09-17 Paul Eggert <eggert@twinsun.com>
18054 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18055 Allow expression to return any value that can fit into unsigned long
18056 (not int, as before). Check for output errors.
18058 2001-09-17 Bruno Haible <haible@ilog.fr>
18060 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18061 Always include <stdio.h> and <stdlib.h>. Evaluate
18062 the expression in an extra function before these includes. Call
18063 fprintf "%d" only after ensuring the argument is of type 'int'.
18064 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18066 2001-09-17 Paul Eggert <eggert@twinsun.com>
18068 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18069 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18070 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18071 when they don't exist.
18073 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18074 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18077 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18078 version with the version used by fileutils 4.1, except use
18079 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

18426 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18427 indeed related to running the test suite, while passing

19010 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19012 Suggested by Russ Allbery.
19014 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19016 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19017 current $prefix to the sub-configures.
19019 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19021 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19022 extension (needed on BeOS). Reported by Guido van Rossum.
19024 2001-08-09 Akim Demaille <akim@epita.fr>
19026 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19028 2001-08-07 Akim Demaille <akim@epita.fr>
19030 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19032 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19033 No need to remove the files before and after the each test, before
19034 each test and at the end of the suite is enough.
19035 Display only the children `times', not the shell's.
19036 If the test failed or was skipped, at-times is not available.
19038 2001-08-07 Akim Demaille <akim@epita.fr>
19040 Always produce testsuite.log, including when there are no
19041 failures. This helps getting information on skipped tests, and
19042 duration of the tests. Err, implement the latter btw.
19044 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19045 Dump information on the first run of each test.
19046 (AT_CLEANUP): Create `at-times' containing the duration of the
19049 2001-08-07 Akim Demaille <akim@epita.fr>
19051 The use of `dumpstat' revealed that `len' was used although it
19052 should not. m4_text_wrap was using it, but in the Autoconf world
19053 where it is legal. Hence (i) test M4sh in its own world, not
19054 Autoconf's, and (ii), ahem, fix the bug :)
19056 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19057 does not like `' instead of [].
19058 (AT_INIT): Forbid `^_?AT_'.
19059 And don't output such tokens.
19060 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19061 `script.as', and `autom4te.cache'.
19062 Remove `empty' and `macro' which are no longer used.
19063 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19064 * tests/m4sugar.at: Use it.
19065 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19067 2001-08-07 Akim Demaille <akim@epita.fr>
19069 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
19071 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
19073 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19075 2001-08-04 Akim Demaille <akim@epita.fr>
19077 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19078 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19080 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19081 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19082 (AC_F77_MAIN): Likewise.
19084 2001-08-04 Akim Demaille <akim@epita.fr>
19086 Don't rely on M4sugar outputting the patterns in files, since we
19087 might process the output _without_ running m4, hence without these
19090 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19091 * bin/autom4te.in (@Request::includes): Remove, unused.
19092 (@Request::source): Rename as...
19093 (@Request::input): this.
19094 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19095 (&handle_output): Fetch the patterns from the traces.

19098 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19100 2001-08-04 Akim Demaille <akim@epita.fr>
19102 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19103 autoconf', i.e., in addition to caching traces, cache the output.
19105 * bin/autom4te.in (Request::cache): Rename as...
19106 (Request::id): this.
19107 ($cache, $icache, $tcache, $ocache): New.

19117 (&parse_args, &print_usage): -f, --force is a new option.

19119 (&parse_args): The first file only can be frozen.
19121 2001-08-04 Akim Demaille <akim@epita.fr>
19123 Don't let autom4te compute the `include' traces several times:
19124 first check that the trace cache file is up to date, and then
19125 compare its timestamp with that of the output.
19127 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19128 the preamble. Don't require 5.005 as Autom4te::General does it,
19129 and better yet (use `use', not `require'!).
19130 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19131 Class::Struct as Autom4te::Struct.
19132 * lib/Autom4te/General.pm (File::stat): Use it.
19133 (&mtime): New, export it.
19134 * bin/autom4te.in: Use it.
19135 Declare `$req' is invalid if it is outdated.

19141 must be proposed to the users.

19186 (m4_divert_pop): Dump the whole diversion stack when a diversion
19188 * bin/autom4te.in (&handle_output): Remember of the first
19189 occurrence of a possibly undefined macro, not the last.

19191 the appear in the output.

19193 * tests/tools.at (autoconf: forbidden tokens, basic)
19194 (autoconf: forbidden tokens, exceptions): No longer sort
19195 autoconf's stderr, as it is now deterministic.
19196 Check that `dnl' is caught.

19219 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19220 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
