85 current directory for atomicity across mount points.
86 * tests/base.at (AC_CACHE_CHECK): Try symlinked cache file.
87 * doc/autoconf.texi (Cache Files): Leftover temporary cache

198 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
199 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
200 &s;" test into the main program, as C99 might plausibly be
201 interpreted as not requiring support for this construction in
202 static initializers. Remove the "#if defined __xlc__" stuff, as
203 the bug is not present in recent xlc implementations, and they
204 reject the test for other (valid) reasons. People using ancient
205 xlc versions, if any, are suggested to update to fixed versions.

220 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by
221 extension clang) check in favor of a gnulib test. Force failure,
222 rather than merely testing for a compiler extension.
224 Reported by Anders Kaseorg.
226 2010-08-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1838 Work around DJGPP shell function return bug with command substitutions.
1839 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1840 shell function which also contains a command substitution causes
1841 the shell to barf. For more details and a fix see:
1842 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>

1872 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1873 and both `conftest' and `conftest.exe' with `-o conftest', but not

6968 Do not pass top_srcdir to configure scripts in testsuite.
6969 * tests/autotest.at (srcdir propagation): Copy install-sh to
6971 (my only test): Drop setting of `top_srcdir'.
6972 * tests/base.at (Input/Output): Likewise.
6973 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6974 config.guess, and config.sub to test source tree.
6975 Drop AC_CONFIG_AUX_DIR setting.
6976 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6977 * tests/torture.at (Substitute a 2000-byte string): Drop
6978 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6979 (Substitute a newline, datarootdir workaround): Likewise.
6980 (Define a newline): Adjust for linenumber changes in configure.ac.
6981 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6983 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6984 if `pwd` contains whitespace.
6986 Quote $abs_top_srcdir in tests.
6987 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6988 * tests/tools.at (Syntax of the shell scripts): Likewise.
6990 * tests/m4sh.at (LINENO): Quote $0.
6992 Fix testsuite program wrapper for whitespace in `pwd`.
6993 The problem here is that the usual mantra is that command
6994 variables can contain arguments, thus we cannot just escape
6995 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6996 $top_builddir/tests directory early in $PATH, so that the
6997 wrappers are found by their plain name.
6998 * tests/wrapper.as: Put $testdir early in $PATH.
6999 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
7001 Proper config.status --file/--header and $srcdir escaping.
7002 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
7003 characters in $ac_file_inputs.
7004 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
7006 * tests/torture.at (datarootdir workaround): Adjust.
7007 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
7009 Fix Autotest for whitespace in `pwd`.
7010 * lib/autotest/general.m4 (AT_INIT)
7011 <at_func_create_debugging_script, Driver Loop>:
7012 Quote $at_group_dir.
7013 * tests/autotest.at (whitespace in absolute testdir): New test.
7015 * lib/autom4te.in: Quote @datadir@.
7017 Proper file name escaping in Autoconf programs and Perl modules.
7018 This includes escaping of characters special to the shell
7019 as well as special to Perl, e.g., leading `<' or `>'.
7020 For example, when $file starts with `>', `open ">$file"'
7021 wrongly tries to append to a different file.
7022 * bin/autoconf.as: Fix quoting for autom4te options.
7023 * lib/Autom4te/General.pm (shell_quote): New function, taken
7024 from coreutils, written by Jim Meyering.
7026 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
7028 * bin/autoreconf.in (parse_args): Likewise.
7029 * bin/autoscan.in (main): Likewise.
7030 * bin/autoupdate.in (main): Likewise.
7031 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
7032 * bin/ifnames.in: Likewise, XFile usage fixes.
7033 * tests/tools.at (autom4te and whitespace in file names): Extend
7034 test. Test twice, with special characters allowed on w32, and the
7035 rest. Test leading and trailing whitespace, for `open_quote'.
7036 (autotools and whitespace in file names): New, analogous test.
7037 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
7038 by Russ Allbery and Eric Blake.
7041 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
7042 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
7043 * lib/Autom4te/FileUtils.pm (open_quote): New function.
7044 (update_file, contents): Use it.
7046 * Makefile.am (autom4te-update): Rewrite for git.
7048 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7050 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
7052 Fix copyright years.
7053 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
7054 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
7056 2007-12-04 Eric Blake <ebb9@byu.net>
7058 Manually resync with gnulib, since 'make cvs-update' no longer works.
7059 * build-aux/config.guess: New upstream version.
7060 * build-aux/config.sub: Likewise.
7062 When using older automake, don't downgrade build-aux/texinfo.tex.
7063 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
7064 * doc/Makefile.am (TEXINFO_TEX): Add.
7066 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
7068 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
7069 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
7070 #undef as this runs afoul of our new way of creating config.h.
7071 Problem reported by Jim Meyering in
7072 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
7074 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7076 Fix autom4te for unusual characters in input file names.
7077 * bin/autom4te.in (files_to_options): Quote active characters
7079 * tests/tools.at (autom4te and white space in file names):
7082 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
7083 Document that Tru64 awk always splits $0.
7085 2007-11-24 Stepan Kasal <kasal@ucw.cz>
7087 * lib/autotest/general.m4 (AT_INIT): Do not extract the
7088 `#AT_STOP_...' line at the end of each test.
7090 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7092 * lib/autotest/general.m4 (AT_INIT): For awk line number
7093 extraction script, ensure `$at_group' has a defined value
7094 even for the empty set, and properly quote its usage inside
7097 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7099 * doc/autoconf.texi (Shell Functions): New chapter. Document
7100 IRIX sh $0 issue in functions, move content from ...
7101 (Portable Shell): ... here.
7102 (Shell Script Compiler): Note that shell functions are not
7103 totally unportable any more.
7105 2007-11-22 Stepan Kasal <kasal@ucw.cz>
7106 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7108 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
7109 extracting the line numbers of the last needed test.
7111 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7113 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7116 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7118 Fix IRIX testsuite debugging failures: $0 in functions.
7119 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7120 Do not use $0 inside a function, as IRIX sh will set that to the
7121 function name rather than the script invocation name.
7123 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7124 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7126 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7127 to extract test scripts.
7128 (AT_INIT): Extract and cache test script line numbers.
7130 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7132 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7133 subsequent fixups; the awk -> here-document conversion trashes
7134 performance too much with AIX sh.
7136 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7138 * tests/local.at: Do not test m4, perl with AT_TESTED.
7140 Diagnose and guard against write errors dealing with config.status.
7141 The general idea is this: all write failures from `configure'
7142 writing `config.status' are indicated by $ac_write_error, which
7143 is only checked at the end. This is safe because config.status
7144 code is not executed before the file is complete. Other write
7145 failures, be they inside config.status, or in sub shell/awk
7146 scripts spawned from configure or config.status, typically need
7147 earlier checking, as their results are used right afterwards.
7148 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7149 before writing config.status, check afterwards.
7150 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7151 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7152 Set `ac_write_error' for write failures to config.status. Barf
7153 upon write failures to temporary files.
7154 Adjust note about closing and reopening the here-document.
7155 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7156 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7157 reopening the here-document.
7158 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7159 Ensure `ac_write_error' does not escape into config.status.
7160 Also, add a couple of code paths not yet exercised in the test
7161 suite: a config file with input from stdin, and a config header
7163 Suggestion for catching write errors by Bruno Haible.
7165 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7167 Avoid error with Tru64 awk and testsuite lines with many words.
7168 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7169 reads the testsuite, set the field separator to an unusual value,
7170 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7171 even splits the input if $i, i>0, was never accessed in the script.
7173 Revert 2007-10-17 change.
7174 * TODO: Multiline args in config files and headers mean something
7175 different and are not fixed, see
7176 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
7177 Report by Stepan Kasal.
7179 * doc/autoconf.texi (Generic Programs): Fix typo.
7181 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7183 AC_*_TOOL does not canonicalize the prefix
7184 * doc/autoconf.texi (Generic Programs): Do not say that
7185 the *_TOOL macros canonicalize, they simply use the `host_alias'.
7187 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7189 Diagnose write errors in config.status instantiations.
7190 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7191 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7193 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7194 Extend test to also check for some write error failures, using...
7195 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7196 Report by Bruno Haible.
7199 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
7201 (_AT_CHECK): Use less indentation, to save space.
7203 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7205 Add witness macro for @top_build_prefix@ substitution.
7206 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
7207 (_AC_OUTPUT_FILE): Mention it here.
7209 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7210 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7212 * lib/autotest/general.m4 (at_func_test): Remove.
7213 (AT_INIT): Pre-extract test groups into separate files.
7214 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7215 Remove at-test-source files together with the $at_group_dir.
7216 * tests/autotest.at (Long test source lines): New test.
7218 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7220 Shell functions and variables may share a namespace.
7221 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
7224 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
7226 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7229 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7231 * lib/autoconf/status.m4: Fix a couple of comment typos.
7233 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7235 2007-11-13 Jim Meyering <meyering@redhat.com>
7237 Clean up the rule to create "expr".
7238 * tests/Makefile.am (expr): Don't redirect directly to target.
7239 Redirect just once, not for each echo statement.
7240 Use $@, not literal "expr".
7242 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7244 Don't worry about preprocessor when testing long long.
7245 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7246 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7247 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7248 These no longer check for preprocessor flaws.
7249 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7250 Do not check for preprocessor flaws.
7252 2007-11-13 Jim Meyering <meyering@redhat.com>
7254 Adapt dependencies, now that a version change doesn't modify configure.ac
7255 * GNUmakefile: Remove "make clean" kludge.
7256 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7258 Don't redirect directly to target.
7259 Use $@, not literal "version.m4".
7261 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7263 * doc/autoconf.texi (Making testsuite Scripts): Document
7264 ":;{" shorthand as in previous patch.
7266 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7268 * doc/autoconf.texi (Limitations of Builtins): Document problem
7269 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7271 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7272 Use ":;{" shorthand.
7273 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7275 2007-11-12 Jim Meyering <meyering@redhat.com>
7277 Add more non-srcdir build support.
7278 * GNUmakefile (dummy): Split a long line.
7279 Add -v option to autoreconf invocation.
7281 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7282 * GNUmakefile (dummy): Remove INSTALL.
7284 Remove racy commands to build scripts in bin/ and tests/.
7285 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7286 are guaranteed to be built, remove the rules that tried to build
7287 them. Before, with a parallel build, these rules could lead to
7288 two processes writing tests/wrapper.in concurrently.
7290 Build in man/ only *after* building in bin/ and tests/.
7291 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7292 in both bin/ and tests/.
7294 Accommodate non-srcdir build-from-checkout.
7295 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7296 Use git's --git-dir=$srcdir/.git option.
7297 Add quotes, in case tarball_version_file contains shell meta-characters.
7298 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7299 * configure.ac: Pass "." to git-version-gen.
7301 Avoid spurious test failures due to version skew.
7302 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7304 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7306 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7307 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7308 Remove conftest.dSYM directory.
7309 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7310 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7311 Remove `conftest.*' recursively.
7312 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7313 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7315 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7317 Report and analysis by Jeff Squyres and Peter O'Gorman.
7319 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7321 Fix typos in variable names.
7322 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7324 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7326 Document that $((expression)) is not portable.
7327 * doc/autoconf.texi (Shell Substitutions): Here.
7329 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7331 Ignore configure --help* errors due to LINENO-impaired shells.
7332 * tests/torture.at (Configuring subdirectories, Deep Package):
7333 In the --help* tests in read-only trees, make `.' temporarily
7334 writable again for the `stderr' file, and ignore errors due to
7335 the attempt to write configure.lineno.
7336 Report by Patrick Welche.
7338 2007-11-10 Jim Meyering <meyering@redhat.com>
7340 Generate package.m4 in build-dir, not srcdir.
7341 * tests/Makefile.am (package.m4): Adjust target.
7342 Don't redirect directly to $@.
7343 (CLEANFILES): Add package.m4.
7344 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7346 When running $(AUTOTEST), search "." before searching $(srcdir).
7348 Avoid a race condition that would make parallel "distclean" fail.
7349 * tests/Makefile.am (distclean-generic): Replace the default,
7350 automake-provided rule with an identical one, but with an additional
7351 dependency on distclean-local. Simply adding the dependency would
7352 cause automake not to emit the rule at all.
7353 * BUGS: Building with -jN works, now.
7355 Distribute git-version-gen.
7356 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7357 since GNUmakefile is distributed, and requires it for dist* rules.
7359 Remove two more generated files from version control.
7360 * INSTALL: Remove generated file.
7361 * lib/autoscan/autoscan.list: Remove generated file.
7363 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7365 * GNUmakefile (PATH): Remove stray apostrophes; they become
7366 part of PATH, which isn't wanted here.
7368 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7370 New config files output variable `top_build_prefix'.
7371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7373 * doc/autoconf.texi (Preset Output Variables): Document it.
7375 Report by Bob Friesenhahn.
7377 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7378 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7379 function, to parametrize arithmetic with expr vs. the shell.
7380 Use it where possible.
7381 Suggestion by Benoit Sigoure.
7383 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7385 Adjust the documentation of autotest WRT atlocal.
7386 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7387 when using Automake, to write a rule to produce atlocal, since it's
7388 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7389 distributed, not atconfig.in.
7391 2007-11-04 Eric Blake <ebb9@byu.net>
7393 Update list information.
7394 * README: Mention new autoconf-commit list.
7395 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7397 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7399 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7401 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7403 * build-aux/.gitignore: Ignore mkinstalldirs.
7405 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7407 2007-11-03 Jim Meyering <meyering@redhat.com>
7409 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7410 * build-aux/git-version-gen: This syncs from coreutils.
7412 Adjust the build procedure so "make check" works reliably.
7413 * README-hacking: Include an extra step between "make" and
7414 "make check" to ensure that the latter passes.
7416 Use just-built tools, when possible.
7417 * GNUmakefile (PATH): Set and export here, ...
7418 (dummy): ... rather than here.
7420 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7421 and Andreas Schwab <schwab@suse.de>
7423 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7426 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7428 * configure.ac (AC_PREREQ): Require version 2.60, for
7429 AC_PROG_SED, AC_PROG_GREP.
7431 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7432 and Jim Meyering <meyering@redhat.com>
7433 and Andreas Schwab <schwab@suse.de>
7434 and Eric Blake <ebb9@byu.net>
7436 Document a bug in GNU Bash with compound commands and redirections.
7437 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7438 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7441 2007-11-03 Eric Blake <ebb9@byu.net>
7443 Support m4 1.4.5 in testsuite.
7444 * tests/torture.at (Define a newline): Exclude line numbers in
7446 Reported by Ralf Wildenhues.
7448 2007-11-03 Jim Meyering <meyering@redhat.com>
7450 Remove automake-provided files from version control.
7451 * build-aux/elisp-comp: Remove file.
7452 * build-aux/install-sh: Remove file.
7453 * build-aux/missing: Remove file.
7454 * build-aux/mdate-sh: Remove file.
7455 * build-aux/.gitignore: New file.
7456 Suggestion from Ralf Wildenhues.
7458 2007-11-03 Eric Blake <ebb9@byu.net>
7460 Adjust version comparison to account for git snapshot numbers.

7486 Suggestions from Ralf Wildenhues.
7488 2007-10-28 Jim Meyering <meyering@redhat.com>
7490 Make inter-release --version output more useful.
7492 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7493 which indicates that it is built using the 19th change set
7494 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7495 is a prefix of the commit SHA1.
7496 * build-aux/git-version-gen: New file.
7497 * configure.ac: Run it to set the version.
7498 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7499 * Makefile.am (dist-hook): Arrange so that .version appears only
7500 in distribution tarballs, never in a checked-out repository.
7501 * .gitignore: Add .version here, too. Just in case.
7502 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7503 not configure.ac, now that the version number changes automatically.
7505 Ensure that $(VERSION) is up to date for dist-related targets.
7506 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7507 git-version-gen doesn't match $(VERSION), but only for dist targets.

7580 Fix config header generation with AIX awk.
7581 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

8936 with traditional Awk and begin.
8937 * tests/torture.at (Limitations of Builtins): Document the problem
8938 with Bash 2.03 printf.
8939 (Substitute and define special characters):
8940 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
8942 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
8944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
8945 input from /dev/null in awk test, so even Solaris /usr/bin/awk
8946 will not wait for input with a script containing only a BEGIN
8949 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
8951 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
8955 2007-02-02 Eric Blake <ebb9@byu.net>
8957 * NEWS: Update copyright.
8959 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
8961 * configure.ac: Update error message.
8962 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

8980 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8982 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8983 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8984 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8985 substitution will still be done by the special code.
8986 Report by Jim Meyering.
8988 * doc/autoconf.texi (File System Conventions): Mention that
8989 $PATH_SEPARATOR is for the build system only.

8995 all non-NUL characters are ok in substituted values.
8996 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
8997 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
8998 carriage return for $AWK, needed for BSD awk.
8999 * tests/torture.at (Substitute and define special characters):
9000 Test all 8 bit non-NUL characters.
9001 Report against Automake by Patrick Welche.
9003 2007-01-15 Stepan Kasal <kasal@ucw.cz>
9005 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
9007 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9009 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
9010 early on the reader side, drop stderr of the input to avoid
9011 `broken pipe' error output; this may happen even with shell
9012 builtin `echo' of some bash versions. Reports by Ian Macdonald
9013 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
9015 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9017 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
9018 separate items of `ac_user_opts', to avoid long lines.
9019 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
9021 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9023 * doc/autoconf.texi: Fix some typos.
9025 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
9027 Fix some wording problems noted by Paolo Bonzini in:
9028 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
9029 * doc/autoconf.texi (Signed Overflow Examples): Give more
9030 discussion about the allow_superuser_privileges example,
9031 and change it a bit to make things clearer.
9032 (Optimization and Wraparound): Clarify whether the compiler
9033 will generate an infinite loop for the example derived from
9034 Autoconf's mktime test.
9035 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
9036 Also, clarify unsigned multiplication overflow.
9038 2007-01-04 Eric Blake <ebb9@byu.net>
9040 * bin/Makefile.am (RELEASE_YEAR): New macro.
9041 (edit): Use it to supply correct copyright year to scripts.
9042 * bin/autoconf.as (version): Use it.
9043 * bin/autoheader.in ($version): Likewise.
9044 * bin/autom4te.in ($version): Likewise.
9045 * bin/autoreconf.in ($version): Likewise.
9046 * bin/autoscan.in ($version): Likewise.
9047 * bin/autoupdate.in ($version): Likewise.
9048 * bin/ifnames.in ($version): Likewise.
9050 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
9052 * doc/autoconf.texi (Integer Overflow): Revised based on today's
9053 feedback. The most important changes document what happens when
9054 you convert an out-of-range value to a signed integer type, and
9055 say that (sum < a) != (b < 0) reliably detects overflow when sum =
9058 * doc/autoconf.texi (Integer Overflow): Greatly expand and
9059 rewrite, taking notions from the recent discussion on the gcc and
9060 autoconf mailing lists; please see
9061 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
9062 and follow the many links.
9063 (Integer Overflow Basics, Signed Overflow Examples):
9064 (Optimization and Wraparound, Signed Overflow Advice):
9065 (Signed Integer Division): New sections.
9067 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
9069 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
9070 preprocessor macro arguments in traced name.
9071 * doc/autoconf.texi (Defining symbols): Document longstanding
9072 support for AC_DEFINE-ing macros with arguments, and document
9073 behavior when the same variable has multiple AC_DEFINEs.
9074 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
9075 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
9076 macros directly, giving much shorter and simpler code.
9078 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
9080 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
9081 space before "$ac_configure_args" to prevent a 'config.status
9082 --recheck' failure if ac_configure_args doesn't contain a leading
9083 space. This works around a problem with the XEmacs configure.ac,
9084 which uses the (undocumented) ac_configure_args variable
9085 inconsistently with Autoconf.
9087 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
9089 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
9090 Include <limits.h>, and use its INT_MAX to rewrite the
9091 j loop so that it does not overflow 'int'. Problem reported by
9093 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
9094 Play it safe by shifting left by 1 rather than multiplying by 2,
9095 as GCC is less likely to optimize this away when the value
9096 is signed (when it assumes overflow leads to undefined behavior).
9097 Also, don't assume time_t uses two's complement.
9099 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9101 * tests/torture.at (Substitute a 2000-byte string): Avoid using
9102 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
9103 dumps core on it. Report by Tim Rice.
9105 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9107 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
9108 --disable-option-checking to --help output even when
9109 AC_PRESERVE_HELP_ORDER is not used.
9110 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
9111 --with argument, rather than argument with [-.] replaced by
9113 * NEWS: Fix typo in previous change; the news was in the
9116 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
9118 * NEWS: Warnings are now generated by default for unknown
9119 --enable-* and --with-* options.
9120 * doc/autoconf.texi (Option Checking): Renamed from
9121 (Configure Option Checking). Tighten up the wording a bit.
9122 (External Software, Package Options): Cross-reference to Option
9123 Checking, and use this to shorten our section.
9124 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9125 "$x" to test "x$foo" != x.
9126 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9127 Don't warn if $enable_option_checking is "no".
9128 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9129 ac_unrecognized_opts to the empty string.
9130 Don't echo the unrecognized opts, as this might mishandle
9131 backslashes or leading -.
9132 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9133 usage next to the other --disable-FEATURE options in the
9136 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9138 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9139 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9140 Print warning for unrecognized --with and --enable options
9141 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9142 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9143 Disable option checking when subdirs are configured.
9144 (AC_OUTPUT): If warnings are enabled, print warning about
9145 unrecognized --with and --enable options at the end of
9146 the configure output (as well as at the beginning).
9147 * doc/autoconf.texi (Option Checking): New node.
9148 Document new option warning functionality.
9150 2006-12-16 Eric Blake <ebb9@byu.net>
9152 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9153 * NEWS: Start news for current version.
9155 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9157 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9158 Define HAVE_GETMNTENT to 1, not to the empty string.
9159 Problem originally reported by Jochen Friedrich in
9160 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9162 This change prompted by a problem report by Andrey Simonenko in
9163 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9164 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9165 object-like macros only, in the traditional portable character
9167 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9168 Warn about attempts to define things that are not identifiers.
9169 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9170 awful hack that AC_DEFINEd macro names containing parentheses.
9172 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9174 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9175 too drastic, even if Texinfo in theory requires it for info mode.
9177 (config.status Invocation): Renamed back from Recreating a
9179 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9180 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9182 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9184 * NEWS: Version 2.61a.
9186 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9187 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9189 * NEWS: Document changes with echo and printf, and the lack
9190 of limits on the total size of multi-line values of substituted
9191 variables, and the AC_FUNC_FSEEKO fix.
9193 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9195 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9196 Writing configure.ac.
9197 (Autoconf Input Layout): Renamed from configure.ac Layout.
9198 (Recreating a Configuration): Renamed from config.status Invocation.
9199 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9200 (acconfig Header): Renamed from acconfig.h.
9201 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9202 (Writing Testsuites): Renamed from Writing testsuite.at.
9203 (Autom4te Cache): Renamed from autom4te.cache.
9205 * BUGS: Remove mention of VPATH problem, since it's now documented
9206 not to be a bug in the Autoconf build procedure itself, but rather
9207 a problem with the proprietary `make' programs.
9209 * doc/autoconf.texi (Build Directories): Add a cross reference
9212 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9213 * doc/standards.texi: Sync from gnulib.
9215 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9216 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9217 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9218 generated automatically.
9220 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9222 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9223 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9224 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9226 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9228 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9229 `CEOF$ac_eof' special marker, the awk script cannot contain a
9230 line matching `^CEOF', so this is not needed any more.
9231 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9232 special marker in the test.
9234 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9236 * tests/tools.at (autom4te preselections): Use `find -newer';
9237 remove one of the sleeps.
9239 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9240 more readable, using ...
9241 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9243 * doc/autoconf.texi (autoheader Invocation): Do not double-
9244 quote the parameter of `AH_BOTTOM' in the example.
9246 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9248 * doc/autoconf.texi (Configuration Headers): Remove the
9249 example with multiple input files.
9250 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9251 multiple input files.
9253 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9255 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9256 creating the awk substitution script, handle one input line at a
9257 time, so that the maximum length of a substituted (multi-line)
9258 value is not limited by the size of the sed pattern space.
9259 The trade-off is a slightly repetitive sed script.
9260 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9261 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9262 * tests/torture.at (Substitute a 2000-byte string): Increase the
9263 test with several long lines, they should not be caught by sed
9266 * tests/tools.at (autom4te preselections): New test, to flag
9267 entries missing from autom4te.cfg.
9268 Report by David Byron <dbyron@hheld.com>.
9270 * tests/torture.at (Substitute a 2000-byte string): Actually use
9271 AC_PROG_AWK, so the last change works as intended.
9272 (Substitute and define special characters): Likewise.
9273 (Substitute a newline): Likewise.
9275 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9276 instead of `awk' consistently.
9277 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9278 * tests/torture.at (Torturing config.status): Test both the
9279 result of AC_PROG_AWK and plain awk.
9280 (Substitute a 2000-byte string): Likewise.
9281 (Substitute and define special characters): Likewise.
9282 (Substitute a newline): Likewise.
9284 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9286 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9287 can be assigned to a function pointer. Problem reported by
9288 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9289 part of a patch by Ralf Wildenhues in that same bug report.
9291 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9293 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9294 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9296 2006-12-01 Eric Blake <ebb9@byu.net>
9298 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9299 cross-compiling from cygwin to mingw.
9300 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9301 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9302 to lib/autoconf/c.m4.
9304 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9306 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9307 string for more reliable failure. Wrap the entire test that
9308 causes the broken Solaris printf to dump core, in a subshell,
9309 so the segmentation fault message is reliably suppressed.
9310 Fix shell expansion errors by using /usr/ucb/echo always;
9311 avoid an error on systems without it by another subshell.
9312 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9313 subshell-$as_echo to `as_echo', for better error message.
9315 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9317 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9318 `BASH_SOURCE' contain a newline, set them to empty, as they may
9321 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9323 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9324 years and is too hard to maintain now. The last straw was
9325 reported by Jerker Baeck in
9326 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9327 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9328 * doc/autoconf.texi (Particular Functions): Move
9329 AC_FUNC_SETVBUF_REVERSED from here...
9330 (Obsolete Macros): ... to here. Say that it does nothing now.
9331 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9332 Turn into (almost) a no-op.
9334 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9336 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9337 These macros are obsolescent and new applications shouldn't need them.
9338 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9339 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
9340 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
9341 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

9343 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
9344 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9345 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9347 * doc/autoconf.texi (Setting Output Variables): Mention that
9348 @VAR1@VAR2 has unspecified behavior. Problem reported by
9350 * NEWS: Mention this.
9352 * Makefile.am: Put only a single '#' into the copyright notice,
9353 so that it's also present in the output file. Standardize wording
9354 in makefile copyright notices to match GNU coding standards.
9355 * bin/Makefile.am: Likewise.

9368 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9370 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9371 in the sed script that mangles the awk script: delete up to the
9372 first exclamation mark only.
9373 * tests/torture.at (Substitute and define special characters):
9376 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9378 Rewrite config files generation: avoid quadratic growth in
9379 the number of substituted variables by using awk instead of sed
9380 for the bulk of the substitutions.
9381 * NEWS: Mention this.
9382 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9383 forbidden in the output (and thus input) file.
9384 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9385 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9386 generate just one large awk script for substitutions,
9387 eliminating much of the earlier complexity, while adding some
9388 new complexity. Only expand the substitution templates at
9389 configure time, for smaller configure script size. If
9390 _AC_SUBST_FILES are used, test 'awk' for working getline support
9391 at config.status time. If absent, interpolate through the
9392 shell. The awk script was written with much help
9393 from Paolo Bonzini and Paul Eggert.
9394 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9395 (_AC_SED_FRAG_NUM): Likewise.
9396 (_AC_SUBST_CMDS): Renamed from...
9397 (_AC_SED_CMDS): ...this.
9398 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9399 * tests/torture.at (Substitute a 2000-byte string): Also
9400 substitute a line with 1000 words, and a variable with several
9402 (Substitute and define special characters): Test awk special
9403 characters, and put substitution input strings `@foo@' in the
9404 output, to test that no recursion happens; test several other
9405 combinations from Paolo Bonzini.
9407 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9409 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9410 that replaced echo with AS_ECHO where this wasn't necessary.
9411 Problem reportd by Ralf Wildenhues.
9412 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9413 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9414 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9416 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9418 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9420 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9422 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9423 that traditional Awk lacks 3-arg "split". It has it.
9424 Mention that FS must be a single character, and a few other
9425 99-byte limits of traditional Awk.
9426 Mention that if (i in a) doesn't work with traditional Awk.

9430 * tests/autotest.at (BSx641-newline in command):

9432 (Newline-CODE-BS-newline in command):
9433 (Single-quote-BS-newline in command):
9434 (Single-quote-newline-BS-newline in command):
9435 Use printf '%s\n' instead of echo, for portability to hosts
9436 where echo interprets backslashes. This will break on hosts
9437 that lack printf, but for now let's assume all such hosts
9438 are dead (if not, we should get reports of test failures).
9440 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9442 'echo' has some portability problems, when given a first argument
9443 with a leading '-', or when given any argument containing '\'.
9444 Avoid using 'echo' in these cases.

9469 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9470 * bin/autoconf.as: Redo verbose flag implementation, as the old
9471 scheme wouldn't work with AS_ECHO.
9472 * lib/autotest/general.m4 (AT_INIT): Likewise.
9473 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9474 Don't use ECHO_T, since ECHO_N is now reliable.
9475 * lib/autotest/general.m4 (AT_INIT): Likewise.
9476 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9477 rather than using a here-document to put the script into a file.

9481 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9482 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9483 bug, but we might as well stop using ECHO_N and ECHO_C internally.

9485 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
9486 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9487 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9488 operand, as AS_ECHO requires. Avoid double file name expansion.
9489 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9490 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9491 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9492 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9493 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9494 Double-quote strings that would otherwise contain M4 comments.
9495 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9497 * configure.ac (AC_INIT): Bump to 2.61a.
9500 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9504 * configure.ac (AC_INIT): Bump to 2.61.
9507 * tests/autotest.at (Macro with backslash in a test title):
9508 Comment out for now, as this tests neither fails nor passes
9509 reliably. Problem reported by Ralf Wildenhues.
9511 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9513 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

9596 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
9599 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9601 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9602 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9603 Imported from a similar patch to gnulib by Bruno Haible.
9605 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

9624 and Stepan Kasal <kasal@ucw.cz>
9626 Handle special characters in test case titles correctly.

9629 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9630 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9631 argument. Extend to check titles printed by ./micro-suite and

9634 Single-quote in a test title,
9635 Double-quote in a test title): Don't expect failure anymore.

9648 * tests/torture.at (#define header templates): M4-quote this title in
9649 AT_SETUP call so that no M4 code is commented inadvertently somewhere.

9654 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9655 `trap ... 0' inside a function, for AIX sh.
9657 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9659 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9660 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9661 5363) simply issues a warning when dividing by zero at compile
9662 time. Problem reported by Elias Pipping.
9664 2006-10-26 Eric Blake <ebb9@byu.net>
9667 * doc/autoconf.texi (Evaluation Macros): Improve the example to

9695 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9696 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than

9698 reported by Nelson H. F. Beebe for Coreutils 6.4.
9700 * tests/tools.at (autoconf --trace: user macros): Remove test
9701 for tracing multiline macros, since m4 1.4.7a uses a different
9702 way to number lines. Problem reported by Ralf Wildenhues.

9778 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9780 (Imported from Automake.)
9781 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9782 which incorrectly sets the mode of an existing destination
9783 directory. In some cases the unpatched install-sh could do the
9784 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9785 system. We hope this is rare in practice, but it's clearly worth
9786 fixing. Problem reported by Alex Unleashed in
9787 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9788 Also, don't bother to check for -m bugs unless we're using -m;

9868 Use a better substitute, by inspecting the output of "ls"
9869 rather than just using ":".
9870 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9871 rather than AS_EXECUTABLE_P, since we needn't worry about
9872 non-regular files here.
9874 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9875 due to configuration hassles with this. See Tonya Underwood's report
9876 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9887 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9888 initialization which is not inherited through the environment

9899 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9900 comment about ac_cpp_err; it was incorrect, and anyway
9901 ac_cpp_err is being removed below.
9902 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9903 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9904 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9906 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9907 with werror_flag and conftest.err and so forth. This is more
9908 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9909 and anyway the user shouldn't normally want to see this gorp logged.
9910 Problem reported by Ralf Wildenhues.
9911 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9912 empty, not 'no', since the rest of the code uses 'test -z'.
9914 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9916 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9917 Use a single call to AC_DO_TOKENS rather than multiple, for
9919 (_AC_LINK_IFELSE): Test that resulting file is executable.
9920 Problem reported by mwoehlke in
9921 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9923 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9924 than creating a file to use with test -x; this is much faster.
9926 2006-10-02 Bruno Haible <bruno@clisp.org>
9928 * lib/autom4te.in (Automake-preselections): Add

9938 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

9946 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9947 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

10302 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
10304 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
10305 pacify insanely picky compilers. Problem reported by Eric Blake.
10307 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
10308 longer supported by Sun.
10310 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
10312 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
10313 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
10314 -Wundef -Werror". Problem reported by David Fang in
10315 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

10331 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
10332 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
10335 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
10337 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
10338 problems with arg script text that doesn't end in newline, and
10339 with '-e a...'. Problems reported by Ralf Wildenhues.
10341 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
10343 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
10344 check for libXt by a check for libX11.
10346 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10348 * doc/autoconf.texi (config.status Invocation): Adjust according
10351 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10353 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
10354 --help' should mention that `--version' outputs configuration
10355 settings. Report by Bruno Haible.
10357 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
10359 Fix test suite failures reported by Pierre in
10360 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
10361 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
10362 the compiler created a file "b.out" when it didn't create anything

10367 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
10369 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
10370 in the restoring of the werror flag.
10372 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
10374 * doc/autoconf.texi (Volatile Objects): Be even a little
10375 less skeptical about "volatile", after discussion with
10376 Bruno Haible on bug-gnulib.
10377 (Limitations of Usual Tools): Warn about sed stripping
10378 leading white space from text. From Bruno Haible.
10380 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
10382 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
10383 compiler complains about it, even if things works after the
10384 complaint. Problem reported by Peter O'Gorman.
10386 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
10387 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
10388 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
10390 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
10392 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
10393 after -R regardless of host. Patrick Welche reports that this
10394 fixes things on NetBSD 3.99.

10404 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
10405 under AC_C_VOLATILE.
10406 (Volatile Objects): Be a little less skeptical about what
10407 "volatile" means. Derived from thoughts by Ben Pfaff in
10408 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
10410 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10412 * doc/autoconf.texi: Fix some typos.
10414 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10416 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10417 more globally, since the 2006-06-30 patch didn't suffice. Problem
10418 reported by Keith Marshall. Also, don't bother with builddir2,
10419 since it shouldn't be needed any more.
10421 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10423 * doc/autoconf.texi (Generic compiler characteristics):
10424 Document AC_COMPUTE_INT. Fix wrong statements on Default

10428 (_AC_COMPUTE_INT): Add obsoletion warnings.
10429 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
10432 * NEWS: Document change.
10434 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
10436 * doc/autoconf.texi (Volatile Objects): New section.
10438 * NEWS: Document previous change.
10440 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10442 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10443 Require that long long int be at least 64 bits wide. C99 requires
10444 this and enough programs depend on it so we should check for it.
10445 Bruno Haible reports in
10446 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10447 that long long int is 32 bits wide with some nonstandard compilers.
10448 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
10450 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10452 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10453 to a nonexistent file, so that we don't have to worry about
10454 a local site configuration that doesn't use /usr/local.
10455 Problem reported by Keith Marshall in
10456 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10458 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10460 * doc/autoconf.texi: Be more consistent about using @acronym with
10461 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10462 quite right (it talked about "OSF/Tru64", even though the
10463 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10464 and it even mentioned "OSF 4"!) and at this point there's little
10465 reason to talk about OSF any more, since it died in 1994.
10466 (Specific Compiler Characteristics): Simplify example of
10467 negative-size array.
10468 (File Descriptors): Reorder to make the text flow better.
10469 Remove joke about "appreciate the various levels"; I didn't get it.
10470 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10471 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10472 (File Descriptors, Limitations of Usual Tools):
10473 Tone down the advice against renaming or removing open files.
10474 (Limitations of Usual Tools): Add a new section, on 'rm'.
10476 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10478 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10479 -lXt in LIBS, idea from Karsten Hopp; this was due since
10482 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10483 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10484 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10485 (which belong to Xt, not X itself). See Debian bug 327655.
10487 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10489 * configure.ac (AC_INIT): Bump to 2.60a.
10492 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10496 * configure.ac, NEWS: Update.
10498 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10500 * config/texinfo.tex: Sync from upstream.
10502 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10503 quadrigraph correctly in traces.
10505 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10508 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10509 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10511 * doc/autoconf.texi (Changed Directory Variables): New node,
10512 to document the whole `datarootdir' business a bit better.
10514 * tests/torture.at (datarootdir workaround): Extend test.
10515 Prompted by report by Alexandre Julliard.
10517 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10519 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10520 when using default mode of IBM C 6 for AIX. Problem and two-line
10521 fix reported by Larry Jones.
10523 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10525 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10526 about literal '${datarootdir}' if a definition is found in the
10529 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10531 * NEWS: Use "M4" rather than "m4" when appropriate.
10532 Problem reported by Eric Blake.
10533 * doc/autoconf.texi: Likewise.
10534 Use @acronym around BSD, GCC, and GNU when appropriate.
10535 (Why GNU M4): Renamed from "Why GNU m4".
10536 (Redefined M4 Macros): Mention that Posix
10537 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10538 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10541 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10543 * bin/autom4te.in (handle_output): Do not forbid the empty
10545 * tests/tools.at (autoconf: the empty token): New test.
10547 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10549 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10550 calls, so that we do not care whether they are LIFO or FIFO;
10551 in the m4_wrap, do not check which diversion is the topmost
10552 one, just check that the stack is balanced at the end.
10553 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10554 base diversion forever--pop the previous diversion before
10555 opening the new one; consequently, remove the m4_wrap call.
10556 * lib/autotest/general.m4 (AT_INIT): Likewise.
10557 * tests/m4sugar.at: Do not use
10558 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10560 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10561 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10563 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10564 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10565 Rework example of m4wrap token-pasting trouble so that it doesn't
10566 care whether it's LIFO or FIFO.
10567 Fix some "contrary to"s that are awkward in English.
10569 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10571 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10572 to `yes' instead of `int$1_t' if the type is found, for more
10573 consistent configure output (where $1 is the number of bits).
10574 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10575 Suggested by Bruno Haible.
10577 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10578 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10579 with system headers. Report by Bruno Haible.
10581 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10583 * config/config.guess, config/config.sub: Sync from upstream.
10585 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10586 in order to avoid picking up an older installed frozen m4sh.m4f.
10587 Besides an outdated shell startup, this could have been created
10588 by an earlier M4 version with incompatible frozen file format.
10590 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10592 * README: Recommend m4 1.4.4 instead of 1.4.3..
10593 * doc/autoconf.texi: Likewise.
10594 (Special Chars in Names): Say that $(.FOO) is portable, as
10595 suggested by Stepan Kasal.
10596 (Installation Directory Variables, Build Directories):
10597 (Automatic Remaking, Subdirectories, Fortran Compiler):
10598 (Making testsuite Scripts, Defining Directories):
10599 Quote variable usages better.
10600 (Making testsuite Scripts): Add clean-local rule to makefile
10601 snippet, by Eric Blake.
10602 (Installation Directory Variables): Fix table item font.
10603 Reword slightly to clarify. Generalize advice about
10604 not using special characters to include all file-related
10605 vars, not just VPATH.
10606 (Special Chars in Variables): Warn about special characters in
10608 (Assignments): Clarify default-value example as suggested by
10610 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10611 (Special Shell Variables): Note leading ./ or ../, as suggested
10613 (Limitations of Builtins): Under cd, warn about CDPATH.
10614 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10617 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10619 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10620 `@var', for texi2html.
10621 (Systemology): Some more word wrapping, for DVI output.
10622 (autom4te Invocation): The short option for `--melt' is `-M',
10625 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10627 * doc/autoconf.texi: More formatting and English tweaks,
10628 many suggested by Ralf Wildenhues.
10629 Reword to avoid "@code{...}'s" and the like, since it's ugly
10630 with Emacs info mode. discontents -> woes.
10631 Put a few "will"s back. time stamp -> timestamp.
10632 side-effect -> side effect.
10634 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10636 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10637 Warn about $@ not persisting. Problem reported by Julien Danjou in
10638 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10639 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10640 Mention other special chars, too.
10642 2006-06-14 Eric Blake <ebb9@byu.net>
10644 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10646 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10648 * doc/autoconf.texi: Some systematic minor improvements, as
10649 follows. Use "makefile" when talking about makefiles
10650 generally (which might be named "makefile" or "Makefile" or even
10651 "foo.mk"), "Makefile" when talking about a specific makefile
10652 called "Makefile". This unclutters the text from weird quotes
10653 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10654 values" rather than "@var{foo}s" and similar constructs containing
10655 "}s". Use "Make rules" rather than "Makefile rules". Minor
10656 English-language improvements. Change the prefix "sub-" to "sub"
10658 Put blank lines around examples more consistently.
10659 Avoid "rather" and "very" as intensifiers.
10660 Avoid "will" as an auxiliary.
10661 (Limitations of Make): Split this node into....
10662 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10663 (Leading _ in Macro Names, Backslash-Newline-Newline):
10664 (Backslash-Newline Comments, Long Lines in Makefiles):
10665 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10666 (obj/ and Make, make -k Status, VPATH and Make):
10667 (VPATH and Double-colon, $< in Explicit Rules):
10668 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10669 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10670 New nodes, resulting from splitup of Limitations of Make.
10671 All cross-references changed. Raise the top node from
10672 a section to a chapter, and all subnodes accordingly.
10673 Redo the introductory wording to match the new organization.
10674 (Installation Directory Variables): Use an example that is
10675 closer to what Autoconf actually does. Mention that VPATH's
10676 value should not contain metacharacters or white space.
10677 (Fortran Compiler): Fix a VPATH bug in an example.
10678 (Leading _ in Macro Names): Mention that this problem is no longer
10679 of practical concern.
10680 (VPATH and Make): Reword the advice to make it clearer
10681 that Autoconf and Automake support VPATH in non-GNU make, but
10682 many packages have bugs in this area.
10683 ($< in Explicit Rules): Refer to Build Directories rather
10684 than using a (non-VPATH-safe) example.
10685 (Automatic Rule Rewriting): Mention the sort of disaster that
10686 can ensue with Solaris-style rule rewriting with VPATH.
10688 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10690 * doc/install.texi (Compilers and Options): Weaken the
10691 suggestion to use GNU make for VPATH builds.
10693 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10694 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10696 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10697 in regular expression.
10699 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10701 * doc/autoconf.texi (Installation Directory Variables):
10702 Drop extra @samp from `@table @samp' item.
10703 (Limitations of Usual Tools): Comment fix.
10704 Do not nest @samp just to point to other table items.
10705 (Writing testsuite.at) <AT_CHECK>: The second argument to
10706 `@dvar' is already @samp'ed.
10707 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10708 do not use @var in the second argument.
10710 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10712 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10713 $as_shell.exe too. Problem reported by Andreas Buening in
10714 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10716 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10718 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10719 `unused variable' compiler warning, for `-Wall -Werror'.
10720 Reported by Jaap Haitsma in
10721 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10723 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10725 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10726 case the compiler dumps core. Problem reported for
10727 OpenServer 5.0.7 by Tim Rice in
10728 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10729 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10732 2006-06-06 Tim Rice <tim@multitalents.net>.
10734 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10735 "ERROR" only shows up in "make check" output if there is an
10738 2006-06-06 Eric Blake <ebb9@byu.net>
10740 * tests/tools.at (automatically allowed tokens): Fix typo.
10742 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10744 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10746 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10747 typically overflows on x86 CPUs, even though the C standard
10748 requires otherwise.
10750 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10752 * configure.ac (AC_INIT): Bump to 2.59e.
10755 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10759 * config/texinfo.tex: Sync from upstream.
10761 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10762 seen, invoke libtoolize with `--ltdl' argument.
10763 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10765 Suggested by Eric Blake.
10767 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10769 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10770 reported by Ralf Wildenhues.
10771 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
10773 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10777 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10779 * doc/autoconf.texi: Modernize some of the references to Solaris.
10781 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10783 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10784 message issued by AC_REQUIRE.
10785 * tests/m4sugar.at: Check m4_require's error message.
10786 * tests/base.at: Check AC_REQUIRE's error message.
10787 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10789 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10791 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10792 `expout' as the last parameter.
10793 * tests/tools.at: Adapt to the above change.
10795 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10797 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10798 information about race-free implementations of mkdir.
10800 2006-06-04 Eric Blake <ebb9@byu.net>
10802 * bin/autoreconf.in (help): Document M4 environment variable.
10803 * bin/autoconf.as (Usage): Likewise.
10804 * bin/autom4te.in (help): Likewise.
10805 * doc/autoconf.texi (autom4te Invocation): Likewise.
10807 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10809 * NEWS: GNU make now recommended for VPATH builds.
10810 Mention that some macros are now documented to be obsolescent.
10811 * doc/autoconf.texi:
10812 Prefer "current" to "modern" to describe
10813 currently-used (albeit perhaps old-fashioned) hosts.
10814 Mention which ancient features no longer need to be worried about.
10815 setgid -> set-group-ID
10816 setuid -> set-user-ID (these are the Posix terms)
10817 Fix some misuses of "only".
10818 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10819 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10820 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10821 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
10822 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
10823 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
10824 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
10825 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10826 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10827 Mention that these macros are obsolescent.
10828 (Installation Directory Variables): shall -> should
10829 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10830 Mention that it's now safe to use 3 and 4.
10831 (Limitations of Usual Tools): cp -r is now specified by Posix.
10832 Omit longwinded and obsolescent discussion of cp -f.
10833 Modernize discussion of expr, ls.
10834 (Limitations of Make): Modernize discussion of VPATH builds.
10835 Mention $? as a workaround in some cases.
10836 * doc/install.texi (Basic Installation):
10837 Mention "./configure; make; make install" first. Be more
10838 specific about why this file is generic. Remove unnecessary
10839 parens. Remove misleading "only". Remove obsolete advice
10840 about csh. Don't say "configure" takes awhile; say it
10841 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10842 and CC=c99 rather than CC=c89, as these are blessed by current
10843 Posix. Recommend GNU make if doing a VPATH build.
10845 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10847 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10848 examples involving shell prompts.
10850 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10851 and Paul Eggert <eggert@cs.ucla.edu>
10853 * doc/autoconf.texi (Here-Documents): Add details about the
10854 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10855 use "here-documents" instead of "here documents".
10857 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10859 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10861 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10863 * doc/autoconf.texi (File System Conventions): Warn about ":"
10864 anywhere in directory names.
10866 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10868 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10869 about quoting the case statement, just in case.
10870 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10871 was fixed in ksh93g; reported by Ralf Wildenhues.
10873 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10875 * doc/autoconf.texi (System Services): Do not document
10876 overriding EXEEXT via ac_cv_exeext=ext.
10877 (Particular Programs) <AC_PROG_MKDIR_P>:
10878 Document that ${MKDIR_P} understands --.
10879 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10882 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10884 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10885 argument with leading hyphen. Problem reported by Paul Eggert.
10887 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10889 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10890 about quoting ac_try: quote all of it, if any of it seems suspicious.
10891 This means we don't have to worry about ${ or sed any more.
10892 Also, double-quote the case statement, to work around misuses via
10893 underquoting as reported by Ralf Wildenhues in
10894 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10895 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10896 undocumented and dangerous macro.
10897 Problem reported by Ralf Wildenhues in
10898 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
10900 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10902 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10903 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10904 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10906 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10908 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10909 since evidently some packages rely on the old, broken behavior.
10910 Problem reported by Ralf Wildenhues in
10911 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10912 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10913 pre-2006-05-26 definitions, but leave in the comments that
10914 these macros are dangerous and should not be used.
10915 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10916 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10917 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10918 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10919 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10921 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10923 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10924 the use of 'tr', since this is our only use of 'tr'.
10926 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10927 and Paul Eggert <eggert@cs.ucla.edu>
10929 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10930 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10932 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10934 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10935 the output file in the `${datarootdir}' test.
10937 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10938 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10940 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10941 mention of `datarootdir' in the input file(s), but literal
10942 `${datarootdir}' in the output file, and we haven't warned yet,
10943 then warn as well: the user may have (erroneously) used
10944 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10945 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10946 * tests/torture.at (datarootdir workaround): Extend this test.
10949 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10950 and Paul Eggert <eggert@cs.ucla.edu>
10952 * doc/autoconf.texi (autoheader Invocation): The first argument to
10953 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10954 alternatives and clear up the language a bit.
10956 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10958 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10959 ac_config_guess, ac_config_sub, ac_configure.
10960 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10961 Fix typo that prevented an unnecessary space from being removed.
10962 Problems reported by Ralf Wildenhues in:
10963 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10965 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10967 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10968 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10969 Don't use the term "thread-safe" to talk about mkdir race
10970 conditions, since the problem is more a process than a thread
10971 issue. Problem reported by Stepan Kasal in:
10972 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10973 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10974 the test for 'install' more closely. Look at MKDIR_P first.
10975 Look in the PATH, and at /opt/sfw/bin.
10976 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10977 Don't bother to try mkdir -p, since we already check mkdir --version;
10978 just look at the version number. (There's no easy way to check
10979 for race-free implementations.)
10980 * tests/tools.at (autoconf: subdirectories): Adjust to above
10981 changes, since MKDIR_P now might end in "/mkdir -p".
10983 * doc/autoconf.texi (autoheader Invocation): Mention that the
10984 first arg of AC_DEFINE_UNQUOTED must be a literal.
10985 Problem reported by Ben Pfaff in
10986 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10988 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10989 * doc/autoconf.texi (Special Chars in Variables): New section.
10990 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10991 (Installation Directory Variables): Quote $(datadir) better.
10992 (Limitations of Builtins): Describe some of eval's trickiness.
10994 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10995 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10996 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10997 in front of every arg, not just trailing args. Quote apostrophes.
10998 (_AC_EVAL_ECHO): New macro.
10999 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
11000 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
11002 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
11003 exposed by quoting of eval argument. Put the command on line line
11005 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
11006 (_AC_PATH_X, AC_PATH_X): Quote more safely.
11007 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
11008 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
11009 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
11010 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
11011 Use eval more safely.
11012 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
11013 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
11015 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
11016 lines, exposed by quoting of eval argument.
11018 2006-05-26 Stepan Kasal <kasal@ucw.cz>
11019 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11021 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
11022 initialization of `ac_cv_exeext', do not override it if it was
11023 already set, unless it was set to `no', for compatibility with
11024 Autoconf-2.13, and comment this.
11025 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
11026 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
11027 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
11028 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
11029 Document that this test may be overridden by setting
11032 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11034 Revert these two patches:
11036 2006-04-06 Eric Blake <ebb9@byu.net>
11037 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11038 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11041 2006-04-01 Stepan Kasal <kasal@ucw.cz>
11042 Clean up _AC_COMPILER_EXEEXT* macros.
11043 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11044 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
11045 ac_file to the name of the default output file and call
11046 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11047 initial `rm' of the candidate files...
11048 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11049 the same list in subsequent `rm' calls, and for the temporary
11050 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11051 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11052 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11053 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11054 no longer needed) by libtool. Make it a cache check.
11055 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11056 copied here by mistake.
11057 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
11058 _AC_COMPILER_EXEEXT.
11059 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
11060 _AC_COMPILER_OBJEXT directly.
11061 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11063 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11065 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
11066 Fix description of how the buggy `sed' works.
11068 2006-05-25 Noah Misch <noah@cs.caltech.edu>
11070 Sync from Automake:
11072 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
11073 ENOLCK. Only mention `make -j' when applicable. Only raise
11074 fatal errors when `make -j' is involved. Improve error message.
11076 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11078 * doc/autoconf.texi (Here-Documents): We now know more about
11079 the variable expansion in here documents bug.
11080 Thanks to Tim Rice and Stepan Kasal.
11082 * doc/autoconf.texi (Making testsuite Scripts): Add an example
11083 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
11085 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11087 * tests/autotest.at (Multiline command from M4 expansion):
11088 No failure to be expected if the shell quotes newlines in
11089 commands in the `set -x' output. Report by Tim Rice.
11092 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11094 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
11095 expansion in the here-documents used by config.status, as that
11096 runs afoul of the Korn shell version M-12/28/93d bug described in
11097 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
11098 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
11099 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
11101 2006-05-23 Jim Meyering <jim@meyering.net>
11103 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
11104 Fix typo introduced with 2006-04-02 change. It reversed the sense
11107 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11109 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
11110 ac_dB slightly, to save bytes in the script.
11111 Max out at 50 lines, rather than 96; this is more likely
11112 (though not guaranteed) to avoid obscure 'sed' failures.
11114 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11116 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11117 `tr -d -' as bad option argument. Work around this by deleting
11118 an unrelated character.
11119 Report by Tim Rice <tim@multitalents.net>.
11121 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11122 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11123 Stepan Kasal <kasal@ucw.cz>
11125 * doc/autoconf.texi (Particular Programs): Do not promise that
11126 we always prefer the GNU version of the program, and that we
11127 search according to PATH; both rules can have exceptions.
11128 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11129 AC_PROG_SED. Move descriptions of limitations
11130 to the Limitations of Usual Tools section.
11131 (Limitations of Usual Tools) <sed>: Mention script length
11132 limitations with Solaris /usr/ucb/sed.
11133 <grep>: Fix wording for empty alternative. Mention that -c and
11134 -l should not be combined, and that -E and -F should not be
11137 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11138 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11140 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11141 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11143 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11145 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11146 AC_DEFINE is now passed to m4_pattern_allow.
11147 * NEWS: Mention that; likewise for AC_SUBST.
11148 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11149 the parameter to m4_pattern_allow.
11150 * tests/tools.at: Add a check for that.
11152 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11154 * lib/autoconf/status.m4: Fix typos.
11156 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11158 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11159 only the files that this macro generates.
11161 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11163 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11164 the HP-UX sed limitation of 99 commands, labels do not count.
11165 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11167 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11169 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11171 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11172 Import the following fix from coreutils:

11176 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11177 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11178 not double-quote uses of that variable, to accommodate the rare
11179 case in which getmntent is available in none of the libraries
11180 checked. This happens at least on FreeBSD 5.0.
11182 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11184 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11185 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11186 some other programs unwisely rely on these undocumented vars.
11187 But put in warning comments about them.
11188 Problem reported by Ralf Wildenhues in
11189 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11190 * NEWS: Document that these variables are intended to go away.
11192 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11194 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11195 and set the language to C++ (analogous to the equivalent Fortran
11198 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11199 * doc/autoconf.texi (C++ Compiler): Document it.
11200 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11203 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11205 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11206 that caused config.status to generate 100-command sed scripts; the
11207 portable limit is 99.
11209 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11211 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11212 variable `ac_d' instead of `d' to avoid infringing namespace.
11213 Report by Ralf Menzel.
11215 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11217 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11218 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11219 * tests/tools.at (autoconf: subdirectories): New test, taken from
11220 the corresponding problem report by Ralf Wildenhues in:
11221 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11223 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11224 Quote some uses of shell variables if they might suffer unexpected
11225 globbing. This doesn't fix all instances of quoting problems that
11226 I found, just the easy ones that look safe.
11227 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11228 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11229 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11230 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11231 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11232 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

11238 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11240 * bin/autoreconf.in ($help): Reword according to the manual.
11241 Suggested by Olly Betts.
11243 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11244 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11246 * bin/autoreconf.in: Pass the directory argument to
11247 `require_configure_ac'. Fix comment.
11248 * tests/torture.at (Configuring subdirectories): Expose this.
11249 Reported by Olly Betts.
11251 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11253 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11254 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11255 Automake as follows:
11257 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11258 `$configure_in' instead of `configure.in', to preserve
11259 directory component.
11261 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11263 * config/config.guess, config/config.sub, config/texinfo.tex,
11264 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11266 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11268 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11269 test for C99 conformance; (bool) 0.5 is an integer constant
11270 expression, but (bool) -0.5 is not. Problem reported by Fedor
11271 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11273 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11275 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11276 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11277 Warn about obsolete install-sh files. Remove stray sentence
11278 fragment and fix cross reference.
11279 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11280 install -d; this undoes the 2006-05-10 change.
11281 (MKDIR_P): Mark with AN_MAKEVAR.
11282 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11283 that we don't require $INSTALL to be thread-safe. Move comments
11284 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11285 of AC_PROG_INSTALL. Output a message saying that we're checking
11286 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11287 MKDIR_P instead of AC_SUBST.
11288 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11289 Special magic for MKDIR_P, too.
11290 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11292 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11294 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11296 Sync from Automake, as follows:
11298 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11299 * config/install-sh: Initialize IFS, so field splitting isn't
11301 * config/mkinstalldirs: Likewise.
11302 * config/missing: Remove superfluous quotes. Replace all uses of
11303 `[' by `test', for consistency, and for..
11304 * config/missing (sed_minuso, sed_output): New variables.
11305 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11306 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11307 Fixes `missing' to detect `--output' for help2man. Fixes
11308 PR automake/483. Report by Dennis J. Linse.
11309 (autom4te): Document in `missing --help'.
11311 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11313 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11314 * config/install-sh: Don't use 'path' to talk about file names,
11315 as per GNU coding standards. Close a race condition reported by Ralf
11316 Wildenhues and Stepan Kasal. There is still a race condition
11317 on hosts that predate Posix 1003.1-1992, but we can't help this.
11318 Don't mishandle weird characters like space on pre-Posix hosts.
11319 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11320 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11321 AC_PROG_MKDIR_P from AS_MKDIR_P.
11322 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11323 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11324 earlier editions are not (including Automake 1.8.3).
11325 Do not suggest mkinstalldirs for thread-safety.
11326 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11327 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11328 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11329 presence of special characters and race conditions.
11330 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11331 in Autoconf's name space.
11333 2006-05-10 Bruno Haible <bruno@clisp.org>
11334 and Paul Eggert <eggert@cs.ucla.edu>

11337 from Automake with minor changes.
11338 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11340 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11342 * config/install-sh: Update to Automake CVS version, as follows:
11343 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11344 * lib/install-sh: Simplify the expr implementation of dirname.
11345 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11346 * lib/install-sh: Handle --, and diagnose unknown options.
11348 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11350 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11351 `./autom4te' to create `./testsuite', since the `all' target
11352 will ensure its presence, but `installcheck' should not create
11353 the uninstalled wrappers.
11355 * tests/torture.at (Unusual Automake input files): Skip if we
11356 detect automake < 1.8.
11358 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11360 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11361 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11362 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11365 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11367 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11368 munge (multiple) white space and other oddities.
11369 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11370 single quotes in variable assignment.
11371 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11372 and similar failures by adding multiple spaces, tabs, and other
11373 special characters.
11374 Report and different test suggested by Francesco Romani
11375 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11377 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11378 single quotes, we only need to search for single quotes; this
11379 both simplifies the search pattern, and makes us less
11380 susceptible to `echo' variations for arguments not containing
11382 (_AC_ARG_VAR_VALIDATE): Likewise.
11384 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11386 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11387 `$*' and IFS concatenation issue with traditional shells and
11388 bash-2.04. Report by Seanster@Seanster.com.
11390 2006-05-03 Bruno Haible <bruno@clisp.org>
11392 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11393 precisely which Mac OS X versions have the od problem.
11395 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11397 * doc/autoconf.texi: Use @option systematically.
11399 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11400 and Bruno Haible <bruno@clisp.org>
11402 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11404 (Integer Overflow): Mention the special case of integer division
11407 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11409 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11410 traditional shells like the Solaris one that do not use the
11411 first IFS character for assembling `$*'.
11412 Prompted by a related report from autoconf_bug@nro.ca.
11414 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11415 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11417 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11418 Mention more problems with the -e option.
11420 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11423 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11425 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11426 in URLs to improve DVI formatted output (requires texinfo 4.6).
11427 (System Services, Systemology, Shellology): Likewise.
11428 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11431 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11433 (Runtime): Fix macro argument names to match description:
11434 `action-if-found' -> `action-if-true' and similarly.
11435 (Obsolete Macros): Likewise.
11436 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11437 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11438 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11440 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11442 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11445 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

11455 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11457 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11458 (Integer Overflow, Null Pointers, Buffer Overruns):
11459 (Floating Point Portability, Exiting Portably): New sections.
11460 (Writing Test Programs): Fix some langauge. Recommend exiting
11461 with status 1, not merely nonzero. Clarify exit declaration.
11462 (Run Time): Move C exit status stuff to new Exiting Portably section.
11463 (Systemology): Mention Posix and levenez. Update v7 reference.
11464 (Portable Shell): Mention the Posix shell.
11466 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11468 * bin/autoconf.as (me): Replace by as_me.
11470 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11472 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11473 since as_me isn't set yet.
11475 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11477 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11478 a few minor bugs in this area.
11480 * doc/autoconf.texi (Programming in M4sh): Comment out the
11481 documentation of AS_BASENAME, for now.
11482 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11483 (Limitations of Builtins) <basename>: Do not refer to
11485 * bin/autoconf.as (me): Don't use AS_BASENAME.
11486 (dir): Remove the unused variable.
11487 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11488 AS_DETECT_REQUIRED. All uses changed.
11489 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11491 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11492 (AS_BASENAME): Use "basename --" to protect against leading "-".

11494 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11495 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11496 (_AS_DIRNAME_PREPARE): Likewise.

11498 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11499 (AS_DIRNAME): Use "dirname --".
11501 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11503 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11504 of "run time" and "run-time" changed to "runtime", for consistency.
11505 * lib/autoconf/fortran.m4: Likewise (in comment).

11507 * lib/autoconf/general.m4: Likewise.
11508 * lib/autoconf/headers.m4: Likewise.
11510 * doc/autoconf.texi (Run Time): Document the exit status situation
11511 with more accuracy and detail.
11513 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11515 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11516 Archive is not officially `GNU' any more. Update URL.
11517 (Defining Directories): Likewise
11518 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11520 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11522 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11523 newline from the `trap' code to finish `config.log'; the NetBSD
11524 /bin/sh resets the exit status after an empty command, as
11525 documented in doc/autoconf.texi.
11526 Reported by Dalibor Topic <robilad@kaffe.org>.
11528 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11530 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11531 Suggested by Bruno Haible.
11533 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11535 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11536 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11537 Instead, just list the shells that we know work.
11538 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11539 changed. Be more cautious about the _cv_ variable.
11540 * tests/tools.at (Syntax of the shell scripts): Check the
11541 _cv_ variable once, at first, to avoid an internal autoconf error
11542 when sh -n does not work.
11544 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11546 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11548 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11550 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11551 use ">&-" since we're only 99.999% sure that this is portable,
11552 and since the MinGW bug is fixed in a different way.
11553 * lib/autotest/general.m4 (AT_INIT): Likewise.
11555 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11557 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11558 before opening config.log, to avoid hitting a bug on MinGW.
11560 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11562 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11563 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11564 This works around a MinGW bug reported by Eric Paire.
11565 Make sure that all writes to the log file append to it,
11566 rather than possibly losing data.
11567 * lib/autotest/general.m4 (AT_INIT): Likewise.
11569 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11571 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11574 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11578 * configure.ac (AC_INIT): Bump to 2.59d.
11580 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11584 * Makefile.maint (news-date-check): Do not require a leading `*'
11585 before the release date in NEWS.
11587 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11588 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11590 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11591 the instantiated file do not contain the string 'datarootdir'
11592 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11593 @mandir@, replace the reference '${datarootdir}' by the value.
11594 * tests/torture.at (datarootdir workaround): New test.
11595 * NEWS: Advertise this temporary fixup.
11596 Based on a patch by Bruno Haible, reported and analyzed by
11597 Paul Eggert and Noah Misch.
11599 2006-04-12 Eric Blake <ebb9@byu.net>
11601 * tests/autotest.at (Debugging a failed test): Fix comment.
11603 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11605 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11606 all the changes since 2006-04-07.
11608 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11610 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11611 succeeded, but `ln -s file dir' failed, take care to remove the
11612 leftover target before the next test, to prevent its spurious
11613 failure; also make sure `ln file dir' works before selecting it.
11614 Thanks to Keith Marshall for pointing this out.
11617 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11618 assignments in `at_debug_args', so that we put them correctly
11619 in the `run' script.
11620 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11621 Reported by Eric Blake.
11623 2006-04-11 Eric Blake <ebb9@byu.net>
11625 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11626 top-level tests after micro-suite has been run. Used in...
11627 (Debugging a successful test, Debugging script and environment),
11628 (Debugging a failed test): ...these new tests. The first of these
11630 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11631 macro, split out from...
11632 (AT_INIT): ...here, so that using -d also generates a run script.
11633 Document that -d inhibits top-level logging.
11634 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11635 inhibits top-level logging; debug scripts are created.
11637 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11639 * tests/autotest.at (Empty test, Empty check): New test to check it.
11641 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11644 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11646 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11647 the files if a problem appears. Make the empty *.at files
11648 read-only, too. Proposed by Ralf Wildenhues.
11650 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11652 * config/Makefile.am: Add comment to force updated Makefile.in.
11654 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11655 space only patch to this file, this patch causes the Makefile.in
11656 files that include freeze.mk to be updated, and thus have a
11657 newer time stamp again, which in turn makes a pristine CVS
11658 checkout have correct time stamps.
11660 * Makefile.maint (cvs-sv): New macro, to be used..
11661 (config.guess-url_prefix, config.sub-url_prefix)
11662 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11663 point to CVS text checkout of Gnulib files.
11664 (copyright-check): Bump current year.
11665 (announcement): Do not hard-wire `./announce-gen'.
11666 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11668 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11670 (wget_files): Update config.guess, config.sub, texinfo.tex by
11671 `wget-update', now that their URLs work again.
11673 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11675 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11676 Problem noted by Paul D. Smith.
11678 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11680 * doc/autoconf.texi: Remove unused words from word list.
11681 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11682 .x-sc_trailing_space: New files.
11684 * doc/standards.texi: Sync from gnulib.
11686 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11687 `LIBOBJDIR' as experimental.
11689 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11690 with a target directory; it's internally implemented as `cp'
11691 anyway, but since Autoconf advertises the possibility to use
11692 a target directory when LN_S is `ln -s', we need to find out.
11693 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11694 analyzed by Keith Marshall <keith.marshall@total.com>.
11698 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11700 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11701 confdefs.h as-is. In general, if it has backslash-newline or the
11702 like, then it doesn't work either to sort or to remove empty
11705 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11707 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11709 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11711 * lib/autom4te.in (Automake-preselections): Preselect
11714 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11716 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11717 apostrophe within a single-quoted string, as this is the usual
11718 tradition and is easier to read than '"'"'. Don't rely on the
11719 shell treating "$/" like '$/'. Use a more-consistent indenting
11720 style for the trap.
11722 2006-04-09 Eric Blake <ebb9@byu.net>
11724 * tests/autotest.at (Backquote command substitution),
11725 (Multiline backquote command substitution): Remove mistaken
11726 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11728 (Parenthetical command substitution, Multiline parenthetical
11729 command substitution): here.
11731 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11733 Import macros from gnulib (often changing their name).

11756 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

11761 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11762 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11763 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11764 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11765 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11766 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11767 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11768 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11769 (Coding Style). Don't mention m4_expand_once.

11790 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11791 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11793 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11795 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11796 of the warning introduced by the 2001-08-28 change.

11801 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11802 variables shall be overriden by the cache.
11803 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11804 that contains braces.
11806 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11808 Revert the patch from 2006-04-01 and only improve
11809 _AS_DETECT_BETTER_SHELL:
11811 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11812 skip nonexistent directories.
11813 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11814 only shell candidates which exist.
11815 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11816 * lib/autotest/general.m4 (AT_INIT): No need to give three
11817 parameters to _AS_PATH_WALK.
11819 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11820 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11822 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11823 distinguish m4sugar macros.
11824 * tests/tools.at (autoupdating with aclocal and m4_include):
11825 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11826 test case by Noah Misch <noah@cs.caltech.edu>.
11828 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11830 Revert my change from 2006-03-17, in other words:
11831 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11833 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11834 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11837 2006-04-07 Eric Blake <ebb9@byu.net>
11839 * doc/autoconf.texi (Programming in M4sh): Document that
11840 AS_MKDIR_P exits the script on failure.
11841 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11843 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11845 * config/elisp-comp, config/install-sh, config/mdate-sh,
11846 config/missing, config/mkinstalldirs: Sync from Automake.
11848 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync

11861 Paul Eggert <eggert@cs.ucla.edu>,
11862 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11864 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11865 whether `set' quotes correctly: redirect stderr of the tested
11866 `set', and use a subshell, for Ultrix; use `sed' instead of
11867 `grep' for zsh `set' which may write binary output; match only
11868 at the beginning of a line, to avoid false positives.
11869 In order to avoid false positives by unrelated variables with
11870 multiline content, put the dump algorithm in a subshell and
11871 unset all variables containing newlines (except some which are
11872 special to the shell). Warn about cache variables that are

11880 * tests/mktests.sh: Reword comments.
11882 * tests/mktests.sh: Only skip internal macros starting with
11883 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11884 Update exclusion lists for the test suite to this end:
11885 (AC_ARG_VAR): Do test this now.
11886 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11887 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11888 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11889 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).

11914 * tests/Makefile.am (maintainer-check-posix):
11915 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
11917 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
11918 ac_config_<foo>s again, sometimes normalized, sometimes not.
11919 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11920 (AC_CONFIG_COMMANDS): Do not do so here.
11921 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11922 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11923 2005-07-25 rewrite. Noticed by Noah Misch.
11925 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

11929 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
11930 inside m4_expand_once; it is redundant.
11932 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
11933 for --help from Cygnus `configure.'
11935 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
11937 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
11938 on a patch proposed by Ralf Wildenhues.
11940 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11942 * lib/autoconf/status.m4: Replace <space>''<tab> with
11943 <tab><space> where this makes sense.
11945 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
11946 Noah Misch <noah@cs.caltech.edu>
11948 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.

11950 * doc/autoconf.texi (Help Formatting): New node.
11951 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
11953 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11955 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
11956 lib/autoconf/specific.m4, lib/autoconf/status.m4,
11957 lib/autoconf/types.m4, lib/autotest/general.m4,
11958 tests/mktests.sh, tests/torture.at: White space cleanup:
11959 remove some SPACE before TAB, or add quoting ('' or @&t@).

11965 2006-04-05 Eric Blake <ebb9@byu.net>
11967 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
11968 empty test suite works.
11969 * tests/autotest.at (Empty test suite): Remove xfail.
11971 2006-04-05 Noah Misch <noah@cs.caltech.edu>

11974 TAGS to ac_config_<foo>s.
11975 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
11976 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
11977 normalizing it, consistent it with previous releases.
11978 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
11980 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11982 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):

11985 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
11987 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
11988 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11989 Use 'comm' rather than N instances of grep; this also fixes a bug
11990 whereby substrings were incorrectly matched, causing us to not
11991 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
11992 (exclude_list): Exclude empty macros.
11993 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
11995 Use awk rather than grep -E or egrep, to avoid
11996 portability problems with regular expressions containing newlines.

11998 Switch from grep to awk syntax.

12005 a subdirectory subject to Cygnus `configure'.
12006 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
12008 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
12009 report request when we have no AC_PACKAGE_BUGREPORT.

12039 * THANKS: Add myself.
12041 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12043 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer

12053 Remove; all uses removed.

12866 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12867 by the function rather than ignoring it.
12868 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12869 comparing its address. Intel's interprocedural optimization was
12870 outsmarting the old heuristic. Problem reported by

12888 Stepan Kasal <kasal@ucw.cz>
12890 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12891 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12892 make its content writable before removing it. Remove an errorneous

12919 suggested by Ben Elliston. Handle weird characters correctly.
12921 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12923 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12924 calls, so that the final expansion of this macro is shorter.
12925 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12926 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12927 the cleanup there. Use AS_VAR_* macros, to be more general.
12928 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12930 * lib/autoconf/general.m4: Use AS_IF where appropriate.

12955 "if $undefined_var;" succeeds with my shell.
12957 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12958 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

12964 Work around bug in Solaris /usr/xpg4/bin/awk.
12965 The bug is present in at least Solaris 8 through 10.
12967 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12969 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12970 some evil values and relying on the fact that $* concatenates the
12971 parameters by the first character from IFS.
12973 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12974 Stepan Kasal <kasal@ucw.cz>
12976 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12977 first header appears, define AH_HEADER.
12978 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12979 Update limitations about when to call AC_CONFIG_HEADERS.
12980 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12981 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12982 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12983 ``Configuration Actions''; fix their index entries.
12985 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12986 options correctly. Process N-M as M-N if M is smaller than N.
12987 Process ranges correctly so that N-N will run only N.
12988 Sort and uniquify the tests that will be run. If there is more
12989 than one test, reinsert the banners for the tests.
12990 * tests/autotest.at (Keywords): Unmark XFAIL.
12992 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12994 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12995 before passing the macro name to AH_TEMPLATE.
12997 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12998 now opens log after option processing; in particular, --version
12999 and --help do not touch config.log.
13001 * Makefile.maint: Revert the change from 2005-08-12.
13003 2005-08-22 Stepan Kasal <kasal@ucw.cz>
13005 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

13011 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
13012 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
13015 * doc/autoconf.texi (Defining Symbols, Changed Results):
13016 Prepend to LIBS, not append, in examples.
13018 2005-08-16 Stepan Kasal <kasal@ucw.cz>
13020 When building in place, set srcdir="."; suggested by Tim Van Holder.
13022 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
13023 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
13024 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
13025 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
13026 does not mean "no --srcdir option".
13028 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13030 * tests/autoscan.at (autoscan): New file.
13031 * tests/suite.at: Use it.
13032 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
13033 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
13035 * tests/autotest.at (Keywords): Test keywords combinations.
13037 2005-08-12 Stepan Kasal <kasal@ucw.cz>
13039 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
13040 add "2>&1"; gzip 1.2.4 prints help on stderr.
13042 2005-07-27 Stepan Kasal <kasal@ucw.cz>
13044 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
13045 was pushdef'ed twice while popped only once. Push it only once.
13046 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
13048 2005-07-26 Stepan Kasal <kasal@ucw.cz>
13050 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
13051 prefixed by mere "===", not "configure: === ".

13055 * Makefile.maint: Update from Bison.
13057 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
13058 "<tab>" in comment, so that the point is understandable.
13060 2005-07-25 Stepan Kasal <kasal@ucw.cz>
13062 Rewrite substantial part of lib/autoconf/status.m4.
13063 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
13064 and CONFIG_COMMANDS are not processed in four separate loops.
13065 Instead, there is one main loop. This alows that the common code
13066 is expanded only once, thus config.status (and configure) is smaller.
13068 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
13069 the AC_LIST_FILES and cousins macros are no longer used.
13071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
13072 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
13073 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
13074 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
13075 contain the initialization, nor the for loop, nor the associated
13076 commands; all these go to ...
13077 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
13078 _AC_OUTPUT_CONFIG_STATUS.
13079 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
13080 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
13081 (_AC_OUTPUT_FILE): The creation of the sed script ...
13082 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
13083 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
13084 _AC_OUTPUT_MAIN_LOOP.
13085 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
13086 _AC_CONFIG_COMMANDS): Use ...
13087 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
13088 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
13089 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
13090 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
13091 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
13092 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
13094 (_AC_CONFIG_UNIQUE): Update.
13095 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
13096 Replaced by this ...
13097 (_AC_LIST_TAGS): ... new common macro.
13098 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
13099 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
13100 (_AC_LIST_TAG_COMMANDS): ... new common macro.
13101 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
13102 this didn't belong to the `config commands' section.
13103 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
13104 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
13105 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
13106 to the `config commands' section either.
13107 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
13108 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
13110 ... and many changes to the comments nearby.
13112 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
13113 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
13114 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
13115 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
13116 (#define header templates): The comment at the top of the generated
13117 header now includes the name(s) of the source file(s).
13119 Several unrelated small changes:
13121 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13122 parameter to AC_DIAGNOSE.
13123 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13124 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13125 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13126 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13127 with AU::AC_OUTPUT.
13128 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13129 in AC_OUTPUT doesn't double-quote it either.
13130 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
13133 2005-07-10 Stepan Kasal <kasal@ucw.cz>
13135 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
13136 versions of Portland Group compiler produce single- and double-quoted
13137 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
13138 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
13140 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
13142 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13143 This is a corrected version of yesterday's patch.
13145 2005-07-07 Stepan Kasal <kasal@ucw.cz>
13147 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
13148 path, too; insert a "===" to emphasize the line.
13150 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
13151 ac_cv_build_alias to ac_build_alias.
13152 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
13154 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
13155 change eliminates it. Problem reported by Alexandre Duret-Lutz.
13156 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13157 (AC_ARG_VAR): ... here.
13158 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13161 Keep a list of all precious variables and process them with one simple
13162 for loop, instead of expanding all commands, or, OTOH, complicated
13163 processing of output of "set".
13164 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
13165 variable names in new macro...
13166 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
13167 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
13168 a loop to assign all ac_env_* and ac_cv_env_* variables.
13169 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
13171 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13172 its value to shell variable ac_precious_vars and call
13173 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13174 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13175 _AC_ARG_VAR_VALIDATE.
13177 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
13178 and the AC_SUBSTs ...

13195 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13196 They are generated by the Tru64 v5.1B shell.
13198 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13200 Fix my changes from 2005-07-01; reported by Noah Misch.
13201 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13202 description, the macro now accepts only a single tag.
13203 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
13205 Fix cases when the varsions of Autoconf and Autotest don't match.
13206 Reported by Noah Misch.
13207 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13208 at_top_builddir, for compatibility with older autotest.
13209 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
13210 is not set, use at_top_builddir, for compatibility with older
13211 versions of autoconf.
13213 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
13215 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
13216 Problem reported by Patrick Welche.
13218 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
13220 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13221 sed substitution command, so that we allow | in program prefixes
13222 and program suffixes. (& is a problem anyway; we're not fixing
13224 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
13225 configure_input, top_builddir, srcdir, etc.
13226 * lib/autotest/general.m4 (AT_INIT): Likewise, for
13227 PATH_SEPARATOR in AUTOTEST_PATH.

13231 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13232 for loop over config.site files using `set', to allow
13233 directory names containing IFS characters.
13235 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13237 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13238 directories with weird names. Apparently some people like living
13239 on the edge. However, improve the test that "pwd" actually does
13240 report a name for the working directory.
13241 * NEWS: Remove the claim that we test for funny chars in dir names.
13243 2005-07-01 Stepan Kasal <kasal@ucw.cz>

13255 about #include <config.h>.
13256 (Generic Functions): Mention the Gnulib project.
13257 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
13259 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13260 document to output the default config_* lists to config.status.
13261 Don't recognize option --file, if the functionality is not there.
13262 Likewise for --header; moreover, recognize --he and --h as shortcuts
13263 for --help in that case.
13265 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13266 matches the order of execution. No code changed.
13268 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13270 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
13271 single-quoted -cmdline argument in Portland Group compiler.

13280 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
13281 descriptors to child processes; reported by Norman Gray.
13283 2005-06-29 Stepan Kasal <kasal@ucw.cz>
13285 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13287 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13288 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13289 (AC_SUBST): Call it.
13290 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13291 the directory specific variables; but don't call it for configure_input.
13293 2005-06-28 Derek Price <derek@ximbiot.com>
13295 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13298 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13300 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13301 directory have inherent problems with special characters like spaces,
13302 due to limitations in Make syntax. Problem reported by Alexandre
13304 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13305 Also, fix Tru64 porting problem with shell patterns,

13316 Fix some more shell quoting problems. Prompted by a bug report
13317 from Justace Clutter.
13318 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13319 variable into diagnostic. Make the diagnostic an error, not a warning,
13320 because we really don't support spaces and suchlike in dir names.
13321 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13322 Don't worry about backslashes in srcdir; it can't happen now.
13323 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
13324 Simplify ac_optarg handling.
13325 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

13332 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
13333 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13335 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13336 that '\|' is not allowed in BREs; recommend using newline separated
13337 list of patterns instead of multiple -e options.
13339 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13341 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13347 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13349 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13350 b, t, r, w commands require single space, while : cannot have any.
13351 (Special Shell Variables): Fix sed code this in the example.
13352 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13353 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13355 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13356 expand to the empty list. Don't use two pairs of m4_changequote,
13357 it's not necessary.
13359 2005-06-20 Derek Price <derek@ximbiot.com>
13361 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13363 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13365 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13366 * doc/autoconf.texi:
13367 Don't mention Solaris versions so much, if a
13368 problem is common to all extant versions of Solaris. Say "SunOS
13369 4" instead of "SunOS" for SunOS 4.
13370 (awk): Mention more of the limitations of traditional Awk.
13371 (cat): Don't talk about cat -v.

13375 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13376 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
13377 but the implementation is entirely different and is designed
13378 to be compatible with glibc strverscmp.
13379 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13381 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
13382 on Mac OS X 10.4 reported by Peter O'Gorman in:
13383 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
13384 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13385 Use shell builtins rather than 'expr', to work around expr bug.
13387 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13389 * doc/autoconf.texi: "filesystem" -> "file system".
13390 "behaviour" -> "behavior".
13391 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13392 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13394 * lib/m4sugar/m4sh.m4: Likewise.
13395 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13396 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13398 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13399 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13400 to update the man page. That way, we don't have to check in new
13401 man pages every month.
13403 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13404 quotes and backslashes. Patch from Derek Price.
13406 2005-06-10 Derek Price <derek@ximbiot.com>
13408 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
13411 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
13413 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13414 -u, since it outputs chatter if the input files are the same.
13415 Problem reported by Ralf Menzel.
13417 2005-06-08 Derek Price <derek@ximbiot.com>
13419 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13420 renaming them since they are about to be redefined anyhow.
13422 2005-06-08 Derek Price <derek@ximbiot.com>
13424 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13425 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13426 Move m4_undefine to alphabetical order.
13428 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13430 * README: Recommend GNU M4 1.4.3 or later.
13431 * doc/autoconf.texi (Introduction): Likewise.
13432 Reword to avoid some formatting glitches.
13433 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13434 Clarify explanation of HP compiler bug.
13435 Redo example output tp match current CVS snapshot.
13436 Use @example.org in email addresses when the examples
13437 might get inadvertently cut-and-pasted into user code.
13438 Remove example of autom4te usage that doesn't seem to work now.
13439 Use modern AC_INIT (except when the example is meant to be
13440 shown with Autoconf 2.13).
13441 Update ksh info for Solaris 9 and later.
13443 Modernize description of Automake versions a bit.
13444 Don't claim a future version of Autoconf is near.
13445 * doc/install.texi: Reword to avoid some formatting glitches.
13447 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13449 * doc/autoconf.texi: Add [] to examples, so that the manual
13450 follows its own advice about quoting better.
13451 Reword to avoid some formatting glitches.
13452 * doc/installt.exi: Reword to avoid some formatting glitches.
13454 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13455 Tru64 ksh pattern matching bug. Reported against Libtool by
13456 Albert Chin <libtool@mlists.thewrittenword.com> and
13457 Nicolas Joly <njoly@pasteur.fr>.
13459 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13461 m4_cdr of one-member list was [[]] (one-member list containing an
13462 empty string) instead of [] (an empty list. Callers were skewed to
13463 match this misbehaviour. As a consequence of this:
13464 - m4_foreach([x], [], [foo]) expanded to `foo', while
13465 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13466 This bug has been fixed:
13468 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13469 expand to an empty string; print error msg if called without
13471 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13472 misbehaviour; handle [] and [[]] correctly.
13474 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13476 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13477 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13478 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13480 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13482 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13483 swallow records with more than 99 fields.
13484 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13485 parse the long line.
13487 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13489 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13490 swallow literals longer than 399. Reported by Ralf Wildenhues.
13491 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13492 to workaround this limitation.
13494 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13496 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13497 to gfortran, and make these the first two compiler names
13498 checked (following the general autoconf preference for gcc).
13500 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13502 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13503 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13504 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13506 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13508 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13509 expression of unbounded size when processing the --list
13510 option. This runs afoul of a limit of 399 bytes per regular
13511 expression on AIX. Problem reported by Ralf Wildenhues.
13513 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
13515 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
13516 * doc/autoconf.texi (Particular Headers): Reword example
13517 for multiline stdbool replacement.
13518 (Setting Output Variables): Reword text a bit. Don't
13519 give all the details about |#_!!_#|.
13520 Reword description of line replacement.
13522 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13524 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13525 now contain newlines, and substituted files must be referenced on
13526 a line alone; the sed scripts to substitute them are now very
13528 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13529 commands can be put in a sed script portably.
13530 * doc/autoconf.texi (Setting Output Variables): Document above
13531 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13532 use of multiline substitution.
13533 * tests/torture.at: No longer expect substitution of newline to fail.

13537 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
13538 From Ralf Menzel (trivial change).
13540 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13542 * tests/local.at: Don't attempt to check for negated character
13543 classes in shell scripts. The test was too brittle.
13545 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13547 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13548 * doc/autoconf.texi (Limitations of Builtins): Document this
13551 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13553 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13554 common code; used in many places in the tree.
13555 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13556 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13558 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13560 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13561 messages when ac_unique_file is not found.
13562 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13563 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13564 commands, for consistency with AC_MSG_ERROR and such.
13566 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13568 * bin/Makefile.am: Merge the two rules for creating scripts.
13570 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13572 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13573 obsolete; it was never documented.
13574 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13576 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13578 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13579 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13580 (ac_top_builddir): ... this ...
13581 (ac_top_build_prefix): ... to this; the old name is also kept, for
13582 backward compatibility.
13583 (ac_top_builddir_sub): New variable, without the trailing slash,
13585 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13586 * doc/autoconf.texi (Configuration Actions): Rename
13587 ac_top_builddir to ac_top_build_prefix.
13588 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13589 at_top_builddir to at_top_build_prefix.

13592 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13594 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13597 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13599 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13600 argument to m4_foreach. I guess it was necessary in the past,
13601 but I think it's a no-op now.
13603 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13605 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13606 ``cat <<_ACEOF'' commands to one.
13607 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13608 * lib/autoconf/status.m4: On various places, use expr instead of
13610 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13611 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13612 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13614 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13615 the wrong patterns between ``case'' and ``esac.'' The previous
13616 code had false positives.
13618 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13620 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13680 abbreviations of --version and --debug.
13682 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13684 * doc/autoconf.texi (Autoconf Language): Be more precise about
13685 quoting rules. Problems noted by Stepan Kasal.
13686 Also, throughout this document, be more careful about white space.
13687 "blank", "white space", and "space" all have different meanings
13688 and we should be careful to say what we mean.
13690 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13692 Fix C++ related problems reported by Werner Lemberg.
13693 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

13711 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13713 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13714 outputs 0 on GNU/Linux these days.
13716 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13718 * doc/autoconf.texi (Autoconf Language): Add more description

13724 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13727 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13728 by AC_DEFINE; it was a mistake.
13729 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13731 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13733 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13735 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13737 * doc/autoconf.texi (External Software): Quadrigraphs are not
13738 processed correctly in AS_HELP_STRING; avoid this in the examples.
13739 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13740 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13741 comment and reduce m4_default([foo], []) to [foo].
13742 (m4_strip): Update the explanation.
13744 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13746 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13747 Remove core.conftest.* too; it's generated by Tru64 5.1.
13748 Problem reported by Jennis Pruett.
13749 * lib/autoconf/functions.m4
13750 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13751 Don't bother to remove core files; AC_RUN_IFELSE should do that
13754 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13756 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13796 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13798 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13799 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13800 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13801 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13802 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13804 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13806 * NEWS: The configure command now warns you if you attempt to use
13807 a directory whose name contains a special character like space,
13809 * doc/autoconf.texi (Installation Directory Variables): Allow
13810 "," in file names. Do not use \@; it's not a portable regexp.
13811 * bin/Makefile.am (edit): Likewise.
13812 * lib/Makefile.am (edit): Likewise.
13813 * tests/Makefile.am (edit): Likewise.

13823 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13824 ac_pwd, and quote srcdir.
13825 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13827 * doc/autoconf.texi: Fix some systematic formatting problems.
13828 ".)" needs a following @: if not at the end of a sentence, and
13829 similarly for "!)". "etc." should be preceded by a comma.
13830 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13832 2005-03-22 Bruno Haible <bruno@clisp.org>
13834 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

13840 macro AC_TRY_LINK is obsolete.
13841 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13844 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13846 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13847 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13848 from a Common Lisp's `cl'.
13849 (AC_PROG_CXX): Behave according to the documentation: don't
13850 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13851 make the variable CCC precious; use `cl.exe', not `cl'.
13853 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13854 Alexandre Duret-Lutz <adl@gnu.org>
13856 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13857 /dev/null, as "configure" shouldn't read stdin, and this insulates
13858 us from problems (e.g., when testing for "cl"). Also, do this
13859 redirection before invoking "hostname" or "uname", and keep the
13860 original input stream available via...
13861 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13862 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13863 bother with "</dev/null" since it's now done at the top of
13865 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13866 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

13872 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13874 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13875 newline if neither \c nor -n work, as that would output two
13876 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13878 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13880 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13881 This causes that any required macros inside will get before the if.
13882 * doc/autoconf.texi (autom4te.cache): A typo.
13884 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13886 Undo previous change, except keep the change to
13887 lib/autoconf/programs.m4 that replaced grep with shell
13888 pattern-matching. This is because net-snmp configure reads stdin.
13889 Reported by Noah Misch.
13891 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13893 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13894 from /dev/null, as "configure" shouldn't read stdin, and this
13895 insulates us from problems (e.g., when testing for "cl").
13896 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13897 before invoking "hostname" or "uname".
13898 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13899 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13900 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13901 "</dev/null" since it's now done at the top of 'configure'.
13902 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13903 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13904 Also, replace grep with shell pattern-matching, to save a process.
13906 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13908 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13909 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13910 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13913 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13915 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13916 grep -q isn't portable. Improve grep -s explanation.
13917 Problem reported by Dan Manthey.
13919 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13921 * doc/autoconf.texi (Special Shell Variables): Clarify
13922 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13924 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13926 * doc/autoconf.texi: Use @acronym for DJGPP.
13927 Fix some @code's that should have been @env's, and vice versa.
13928 Sort environment variable names.
13929 Mention that shells no longer inherit IFS.
13930 Don't recommend PATH_SEPARATOR=';' so strongly.
13931 Mention that $RANDOM might expand to the empty string.
13932 "symlink" and "soft link" -> "symbolic link".
13933 Improve mktemp description (reported by Bruno Haible).
13935 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13937 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13938 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):

13943 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13945 * NEWS: Mention AT_COPYRIGHT.
13947 * tests/local.at (AT_CMP): Use diff directly on input files rather
13950 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13951 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

13963 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13964 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13965 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13970 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13971 CPPFLAGS to `configure' instead of setting it in `configure'.
13973 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13974 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

14008 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
14009 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

14012 2047-byte limit on line length of portable text files.
14013 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
14014 Use newline as a separator, not space.

14023 are restored after function return.
14025 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
14027 * doc/autoconf.texi (Special Shell Variables): Mention _,
14028 BIN_SH, DUALCASE. Say that variables other than "status" are safe
14029 if they contain a lower-case letter. The DUALCASE problem was
14030 reported by Ralf Wildenhues.
14032 * bin/autoconf.as: Don't exit with status 0 after write failure
14033 with --help or --version.

14040 Unicos 9 sed limitations.
14041 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

14047 * man/Makefile.am (.x.1): Go back to the simple solution, but take

14072 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
14073 Update the long comment explaining it.
14075 m4_require no longer writes an ``is required by'' line to the
14076 execution stack. It contains only one bit of non-redundant
14077 information: that the macro was required, not called. And even
14078 this bit is useless in most situations: have you ever met a macro
14079 which both calls and requires the same macro?
14081 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
14082 (_m4_defun_pro_outer): ... only via this macro, for the outermost

14085 (m4_expansion_stack_pop): Remove the misplaced comment.
14086 (m4_require): Don't put the ``is required by'' line to the
14087 execution stack; slightly improve the out-of-a-defun error message.
14088 (_m4_divert_grow): New macro, counter for the temporary diversions.
14089 (_m4_require_call): Use it.
14090 * tests/m4sugar.at (m4_require): Expect output without the
14091 ``is required by'' messages.
14093 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
14095 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
14096 rather than x for expr.

14113 from masters, so that FileUtils.pm's update_file provide --force
14115 * bin/autoheader.in: Pass $force to update_file so that
14116 config.h.in is always recreated when --force.

14122 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
14124 * doc/autoconf.texi (Limitations of Builtins): Clarify that
14125 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
14127 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14129 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14130 Warn about newline stripping in `` and $(). Update Solaris
14132 (Limitations of Builtins): Use expr "X...", not expr "x...", as
14133 X insulates us from future changes to Posix.
14134 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
14137 2005-01-19 Stepan Kasal <kasal@ucw.cz>
14139 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

14156 reported by Michael Jennings via Daniel Reed; see
14157 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
14159 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
14161 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
14162 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
14163 datadir, infodir, and mandir. Adjust argument parsing code.

14182 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
14183 (_m4_divert_n_stack): New macro; the expansion is
14184 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14186 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14187 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14188 stored in _m4_divert_diversion or _m4_divert_dump.
14189 (m4_divert_pop): When the parameter is given, compare the symbolic
14190 name with the last diversion pushed on the stack. Previously, the
14191 current diversion was compared with the numeric value of the
14192 diversion given as the parameter.
14193 (m4_require): If the macro hasn't been expanded yet, call ...
14194 (_m4_require_call): this new macro.

14227 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
14228 signals that the package uses Automake; a `Makefile.am' is typical but
14229 not essential. Reported by Magnus Therning.
14230 * tests/torture.at (autoreconf.): New banner.
14231 (autoreconf and non-AC configure): Rename to `Non-Autoconf

14723 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
14724 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
14725 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14726 * lib/autom4te.in (Automake-preselections): Preselect
14727 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14729 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14731 * lib/autom4te.in (Automake-preselections): Preselect
14732 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14735 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14737 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14739 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14740 Document problem with "`""`" in pdksh POSIX mode.
14742 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14744 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14745 with pdksh, too. Problem reported by Patrick Welche via
14747 * doc/autoconf.texi (Shellology): Note that set -o posix is
14748 useful for pkdsh, too.
14750 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14752 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14753 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14754 Don't fail if ENV or BASH_ENV is readonly.
14755 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14756 etc. are read only. Problem reported by Ludovic Courtes.
14758 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14760 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14761 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14764 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14766 * doc/autoconf.texi (File System Conventions): Warn about
14767 names like "aux". Problem reported by Eric Blake.
14769 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14770 by zero instead of array size, so that we can use any arithmetic
14771 constant expression (instead of requiring an integer constant
14772 expression). This allows us to test expressions like DBL_MAX <
14773 LDBL_MAX, which didn't conform to the C standard using the old
14775 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14776 now that we can do floating-point tests at compile time.
14778 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14780 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14781 and LDBL_EPSILON, as the resulting expression isn't an
14782 integer constant expression and violates the C standard.
14783 Problem reported by Nelson H. F. Beebe. Also, check
14784 for "L" suffix, and check that long double doesn't have
14785 worse range or precision than double, that mixed-mode
14786 arithmetic doesn't generate a diagnostic, that double
14787 constants fit in long double.
14789 2004-06-03 Kevin Ryde <user42@zip.com.au>
14791 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14792 malloc(0) and realloc(NULL,size).
14794 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14797 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14799 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14800 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14803 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14805 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14806 can be rewritten using if-then-else. Suggested by Bruno Haible.
14808 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14810 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14811 Problem reported by Stepan Kasal.
14813 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14815 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14816 change). Patch reported by Ralf Wildenhues in
14817 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14819 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14820 function F exists if the compiler and linker let you compile an
14821 expression like (F != 0). Recent versions of GCC optimize away
14822 the reference to F in that case, since every function address must
14823 be nonzero, so the link succeeds even if F does not exist.
14824 Problem reported by Manu in
14825 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14827 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14828 "Unix". Many uses changed.
14829 (Limitations of Builtins): Explain better why the ! command isn't

14834 * lib/autom4te.in (Automake-preselections): Preselect
14835 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

14839 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14840 referencing AC_FUNC_STRERROR_R.
14842 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14843 note pessimistic assumption when cross compiling.
14845 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14847 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14848 (until 2004) invoked subcommands with sh -e, contra POSIX.
14849 Reported by Kevin Ryde.
14851 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14853 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14854 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14855 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14856 `test -f " /usr/bin/grep"', which _always_ failed.
14857 (AC_PROG_SED): Ditto bogus PATH fix.
14858 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14859 requires that grep correctly supports _multiple_ `-e' options, rather
14860 than stating only that grep should accept `-e'.
14862 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14864 Port to C99, which requires that 'exit' be declared.
14866 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14867 to ensure that stdlib.h is included.
14868 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14869 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14870 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14871 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14872 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14873 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14874 when using 'exit' in a test; C99 requires that 'exit' be declared.
14876 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14878 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14879 now prefers 'grep' implementations that accept -e.
14880 (Limitations of Usual Tools): Describe problems of traditional
14881 egrep and fgrep with long input lines, and of traditional grep
14883 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14884 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14885 All callers changed. Append /usr/xpg4/bin to the PATH, for
14887 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14888 the user with complaints about multiple -e options.
14889 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14890 Define it with AC_PROG_GREP.
14891 * configure.ac (AC_PROG_GREP): Add.
14892 * lib/freeze.mk (GREP): New macro.
14894 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14896 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14897 a possible candidate only after all others fail, rather than
14898 consulting it first. This improves backward compatibility by
14899 better reflecting the way shell selection occurred in previous
14900 versions of Autoconf, and should help to avoid triggering latent
14901 problems in other packages, such as the one in Automake where zsh
14902 is not handled robustly:
14903 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14904 Although it is not Autoconf's responsibility to work around
14905 problems in Automake, it nevertheless makes sense to avoid
14906 introducing unnecessary incompatibilites.
14908 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14909 Gary V. Vaughan <gary@gnu.org>
14911 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14912 how deeply nested we are when a suitable tool is found, set the
14913 ac_path_TOOL_found flag.
14914 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14915 nested we are in this macro. Break out of all 3 nested loops if
14916 ac_path_TOOL_found is set.
14918 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14920 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14921 of the _AS_PATH_WALK loop too if GNU flavor is found.
14923 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14925 * doc/autoconf.texi (Limitations of Make): Update documentation
14926 for `$<'. New entry `Long lines', based on a report from Simon
14927 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14928 paragraph about DJGPP, based on a mail from Richard Dawe.
14930 2004-04-20 Paul Eggert <eggert@twinsun.com>
14932 * tests/c.at (C keywords): Don't assume that GCC supports
14933 "restrict" and "inline", as sufficiently-old GCC versions do not
14934 (also, GCC configured to be in pedantic C89 mode does not).
14935 Problem reported by Sumit Pandya in:
14936 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14938 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14939 consider -g to work if it generates warnings when plain compiles
14940 don't. Problem reported by Braden McDaniel in:
14941 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14943 * doc/autoconf.texi (Slashes): New section, to document a problem
14944 reported by Jim Meyering in:
14945 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14947 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14948 linker output files before linking, to work around IRIX 6 linker bug.
14949 Problem reported by Rainer Orth in:
14950 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14952 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14954 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14955 best tool so far counter rely on the tool path variable name to
14956 avoid checks for one tool being affected by the results of running
14957 the length check on a previous tool.
14959 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14960 match expression argument, as different greps have different
14961 regular expression flavours.
14962 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14964 (AC_PROG_EGREP): Pass 'EGREP$'.
14965 (AC_PROG_GREP): Pass 'GREP$'.
14967 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14969 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14970 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14972 2004-03-29 Paul Eggert <eggert@twinsun.com>
14974 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14975 Types, Specific Compiler Characteristics, System Services,
14976 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14977 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14978 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

14992 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14993 now defines HAVE_DECL_TZNAME if it is declared, when
14994 HAVE_STRUCT_TM_TM_ZONE is not defined.
14995 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14996 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14999 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
15001 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
15002 superfluous backslashing of quotes (") in sed expressions;
15003 thanks to Paul Eggert.
15005 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
15007 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
15008 Fortran compiler is ifort, also added pghpf; thanks to Nelson
15009 H. F. Beebe for the bug report.

15054 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
15055 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
15056 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
15058 (AC_CHECK_ALIGNOF): New macro.
15059 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

15065 * bin/Makefile.am (edit): Don't use $< in a context where
15066 POSIX doesn't require support for it. Use $@.in instead.
15067 Problem reported by Anthony N. Frasso in
15068 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

15097 AC_SUBST provides no portable way to escape literal newlines.
15099 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
15100 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
15101 Darwin uses -lcrt2.o and there's little point to cataloging all
15102 the system variants. Partial fix reported by Andreas Waechter in:

15128 Paul Eggert <eggert@twinsun.com>
15130 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
15131 (AS_INIT): Output shell initialization there. Removed optional
15132 parameter. Expand _AS_SHELL_FN_SPY.

15179 2003 (except 1997) to the list of copyright years. This undoes
15180 the 2003-05-22 change, which removed the older years from the list.
15181 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

15189 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

15192 egrep and fgrep respectively if $GREP -E/-F don't work.
15193 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15194 _AC_PROG_GREP, and AC_PROG_SED.
15195 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
15196 longest input length accepted by a command.

15201 2004-01-27 Paul Eggert <eggert@twinsun.com>

15227 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15228 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15229 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15230 not <inttypes.h>. Problem reported by Tim Mooney in
15231 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15232 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15235 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15236 otherwise "make check" fails because it forbids cmp (I guess
15237 because cmp treats files as binary on DOS-like systems).
15239 * tests/mktests.sh: Update copyright date to 2004, since some tests
15240 have changed in 2004.
15242 2004-01-23 Gary V. Vaughan <gary@gnu.org>

15245 non-truncating sed or gsed program in PATH.
15246 * tests/acprograms.at: Add it.

15250 2004-01-15 Paul Eggert <eggert@twinsun.com>
15252 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15253 -std1 disables some useful extensions on Tru64. Problem reported
15254 by N. Lichtmaier in
15255 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
15257 2004-01-14 Paul Eggert <eggert@twinsun.com>
15259 * doc/autoconf.texi (Programming in M4sh): Document that
15260 AS_MKDIR_P succeeds if the destination is a symbolic link
15261 to an existing directory.
15262 (Limitations of Usual Tools): Note that mkdir -p might not
15263 succeed on symlinks to directories.
15265 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15267 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15268 * bin/autoheader.in: Grammar fix in message.
15269 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15270 Test for dir before calling mkdir -p. (trivial changes)

15275 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
15277 2004-01-10 Jim Meyering <jim@meyering.net>
15279 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
15281 2004-01-09 Paul Eggert <eggert@twinsun.com>
15283 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15284 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15285 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15286 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15287 AC_COMPILE_IFELSE, since we now assume our caller invokes
15288 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15289 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15290 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15291 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15293 2004-01-07 Paul Eggert <eggert@twinsun.com>
15295 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15296 `"'...'"`, as it's confusing (and I suspect it may not work on
15297 some platforms). The code was incorrect anyway, as it assumed
15298 that \$ evaluated to itself in that context. Reported by
15299 Alexandre Duret-Lutz.
15301 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15303 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15304 and _LT_AC_TAGCONFIG.

15331 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15332 Use "rm -f" to remove conftest.sed, not plain "rm".
15333 Bug reported by David Relson in
15334 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15336 * Makefile.am (autom4te-update):
15337 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
15338 * Makefile.maint (my-distcheck, do-po-update): Likewise.

15353 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
15354 -c -o might not work. From a suggestion by Kevin Ryde.
15355 (C Compiler, Generating Sources, Limitations
15356 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15357 Don't put '-o' after non-options, as POSIX doesn't allow this.
15358 Mention that cc's name might be gcc or c89 or whatever.
15360 2004-01-04 Kevin Ryde <user42@zip.com.au>
15362 * doc/autoconf.texi: Add various further index entries.

15369 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
15371 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
15372 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
15373 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
15374 explanation clearer.
15376 2003-12-24 Andreas Schwab <schwab@suse.de>
15378 * doc/autoconf.texi (Default Includes): Fix misspelling of

15384 * configure: Regenerate.
15385 * tests/atlocal.in: Store the result here.

15388 of explicitly testing.
15389 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
15390 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15391 * tests/tools.at (Syntax of the shell scripts): Simplify

15468 2003-11-17 Paul Eggert <eggert@twinsun.com>
15470 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
15471 into the initial confdefs.h, to work around a bug in NextStep 3.3

15474 2003-11-15 Kevin Ryde <user42@zip.com.au>
15476 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
15477 than $target since the latter is not usual, add guidelines on when to
15478 use or not use the system type.

15623 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in
15624 pdksh 5.2.14. Bug reported by Ralf Corsepius.
15625 * doc/autoconf.texi (Shellology): Mention the Korn shell and pdksh.
15626 Mention /usr/dt/bin/dtksh on Solaris.
15627 (Shell Substitutions): Warn about $((...)).
15628 (Parentheses): New section.
15630 2003-10-15 Kevin Ryde <user42@zip.com.au>
15632 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
15633 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
15635 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
15637 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
15640 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
15642 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
15643 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
15645 2003-10-10 Andreas Schwab <schwab@suse.de>
15647 * bin/autoheader.in: Avoid empty first line in --version and
15649 * bin/ifnames.in: Likewise.
15651 2003-10-09 Paul Eggert <eggert@twinsun.com>
15653 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
15654 Issue a more-informative diagnostic.
15655 Problems reported by Eric Sunshine.
15657 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
15659 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
15660 -mGLOB_options_string stuff for Intel ifc, which can cause
15661 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
15662 pattern-matching instead of grep.
15664 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
15666 * doc/autoconf.texi: Document new FC Fortran macros.
15668 2003-10-08 Gary V. Vaughan <gary@gnu.org>
15670 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
15671 that future autopoint/aclocal/automake/autoreconf will be able
15672 to trace to find where to install local m4 macros.
15673 * doc/autoconf.texi (Input): Document it.
15676 2003-10-06 Gary V. Vaughan <gary@gnu.org>
15678 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
15679 -lcrtbegin.o to list of ignored flags and fix underquoting of
15682 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
15684 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
15685 cache variable instead of $G77 to decide whether to include -O2,
15686 since $G77 is specific to Fortran 77.
15688 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15690 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
15691 free" flag. Re-order flags tested into rough order of popularity.
15693 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15695 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
15696 arguments so that it can be used with syntax identical to
15697 AC_PROG_F77, and so that we can more easily decide to
15698 remove/deprecate the DIALECT optional argument in the future if it
15699 proves troublesome.
15700 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
15701 non-freeform-supporting compilers. Document freeform flags.
15703 2003-10-03 Akim Demaille <akim@epita.fr>
15705 * configure.ac: Look for emacs, not macs.
15706 Reported by Eric Sunshine.
15708 2003-10-03 Akim Demaille <akim@epita.fr>
15710 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
15711 * bin/autoreconf.in (autoreconf_current_directory): Create the
15712 AUX_DIR if needed, for sake of automake --add-missing etc.
15713 Suggested by Alexandre Duret-Lutz.
15715 2003-10-03 Akim Demaille <akim@epita.fr>
15717 * configure.ac: Quotation and formatting changes.
15718 (EMACS): Don't set it if it is not recent enough to support

15764 Problem reported by Lars J. Aas in
15765 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15766 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15767 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
15768 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
15770 2003-09-26 Akim Demaille <akim@epita.fr>
15772 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15773 directory for AC_CONFIG_COMMANDS' first argument exists.
15774 This makes valid the invocation of _AC_SRCPATH that follows.
15775 Reported by Eric Sunshine.
15776 * doc/autoconf.texi (Configuration Commands): Adjust.
15778 2003-09-26 Akim Demaille <akim@epita.fr>
15780 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
15781 Reported by Ralf Corsepius.
15783 2003-09-26 Akim Demaille <akim@epita.fr>
15785 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
15787 Actually, use AU_ALIAS.
15790 2003-09-26 Paul Eggert <eggert@twinsun.com>
15792 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
15793 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
15794 Problem reported by Eric Sunshine in:

15799 The test suite are sometimes assigning timings incorrectly.
15800 Reported by Henk Krus.
15801 Diagnosed by Nicolas Joly.
15803 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15805 Instead of making AT_help a sequence of assignments to grow
15806 $at_help_all, just make AT_help_all be the growing contents of
15807 $at_help_all, and make a single assignment in...
15809 (at_times_skip): Flip the meaning and rename as...
15810 (at_times_p): this.
15811 (AT_INIT): When summarizing the test that ran, remove
15812 $at_times_file after use, and check it is present before trying to
15815 2003-09-25 Akim Demaille <akim@epita.fr>
15819 * bin/Makefile.am (edit): Handle '@configure_input@'.
15820 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
15821 (ifnames): chmod -w.
15822 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15823 executables, not bin/ executables! Otherwise all the magic needed
15824 to find non installed files is turned off. This caused a failure
15825 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15826 as found in its environment (sent by tests/autoreconf): pointing
15827 to bin/autom4te that could not find its files.
15828 * tests/mktests.sh: Force the replacement of generated files, for
15829 the sake of "mv" program that are interactive when overwriting a
15831 * config/install-sh: Upgrade from CVS Automake.
15833 2003-09-23 Paul Eggert <eggert@twinsun.com>
15835 * doc/autoconf.texi (Limitations of Builtins): Document test -h
15836 versus test -L issues.
15838 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15839 Paul Eggert <eggert@twinsun.com>
15841 Trivial change to support GCC's configuration procedure.
15842 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
15843 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
15844 about inconsistency if the preprocessor is set to give errors for

15874 2003-09-10 Akim Demaille <akim@epita.fr>
15876 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
15877 willing to edit the output files.
15879 2003-09-10 Akim Demaille <akim@epita.fr>
15881 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
15882 and AC_FC_FREEFORM.
15883 * tests/mktests.sh: Skip AC_FC_SRCEXT.
15884 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

15904 2003-09-05 Paul Eggert <eggert@twinsun.com>
15906 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

15909 2003-09-04 Akim Demaille <akim@epita.fr>

15920 2003-09-04 Akim Demaille <akim@epita.fr>
15922 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
15924 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15926 Add support for newer Fortran dialects. The F77 interface is
15927 unchanged, and continues to support Fortran 77. New FC macros
15928 correspond to all the old F77 macros, with output variables FC,
15929 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15930 available dialect, but older dialects can be specified. There are
15931 new macros AC_FC_SRCEXT to set the source extension, and
15932 AC_FC_FREEFORM to accept free-form source files.
15934 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
15936 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
15937 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

15952 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
15953 Rewrite in terms of the above.
15954 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
15955 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
15956 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
15957 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

15962 Document problems with timestamp resolution that 'make', 'cp -p', and
15965 2003-08-27 Akim Demaille <akim@epita.fr>
15967 * tests/m4sugar.at (cross_warning): Make sure to enable the

15969 * tests/local.at: Require 2.57.
15970 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
15971 are defaulted by AT_CHECK anyway.
15972 Use AT_CHECK_AUTOM4TE.
15973 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
15976 2003-08-27 Akim Demaille <akim@epita.fr>
15978 * bin/autoheader.in: Issue the "Using auxiliary..." message only

16027 Output stack traces in warnings.
16029 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
16030 Replace the former...
16031 (m4_warn): Pass the call stack to _m4_warn.
16032 * bin/autom4te.in: Adjust to output the call stack.
16033 * tests/m4sugar.at (m4@&t@_warn): Adjust.
16035 2003-08-22 Akim Demaille <akim@epita.fr>
16037 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

16040 2003-08-21 Akim Demaille <akim@epita.fr>
16042 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
16043 (&verbose): Remove.
16044 (&getopt): Adjust the note and verb channels, depending upon
16046 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
16047 * bin/autoupdate.in: Adjust.
16048 Use &verb, not &verbose.
16050 2003-08-21 Akim Demaille <akim@epita.fr>
16052 * bin/autoheader.in (&parse_args): Use &parse_warnings and
16054 ($help): Use Autom4te::ChannelDefs::usage.
16055 * bin/autoscan.in: Use Autom4te::ChannelDefs.
16056 * lib/Autom4te/General.pm: Don't export error: you don't own it.
16058 2003-08-21 Akim Demaille <akim@epita.fr>
16060 First stab at preserving warnings between calls to autom4te,
16061 including when the cache is used.
16063 There are still several issues: (i) there are too many runs of m4
16064 (one for include, one for warnings, and some more), (ii) warnings
16065 spreading on several lines are not handled gracefully, (iii) the
16066 code meant to have the call stack display for errors does not work
16067 (its handling should move from m4 to autom4te).
16069 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
16071 (@preselect): Add m4_warn.
16072 ($exit_status): Remove, use $exit_code.
16073 ($help): Use Autom4te::ChannelDefs::usage.
16074 (&handle_m4): No longer define the m4_warnings.
16075 At each run, extract and report the warnings.
16076 Always cache the result, including if the exit status is on
16077 failure, since if nothing changes, we should result in the same
16078 failure, hence we can use the cache.
16079 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
16080 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
16082 (m4_warn): Redefine as a do-nothing: it is its invocation that
16083 matters, as warnings are now reported via traces.
16084 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
16085 the contents of m4_warn: make it _call_ m4_warn, so that tracing
16086 the latter reveals calls to the former.
16090 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
16092 2003-08-21 Akim Demaille <akim@epita.fr>

16102 (&parse_warnings): Accept a list of warning requests.

16128 (&xsystem, &contents): Remove, since they are exported by...

16218 -lcrt1.o, for OS X. (trivial change)

16247 From Gareth McCaughan.
16249 2003-06-23 Akim Demaille <akim@epita.fr>
16251 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16252 not all of them. This fixes 1. the fact that when testing
16253 Autoconf there are many many config.log, 2. the incorrect use of
16254 top_srcdir to find config.log.
16255 Don't mix the detailed output of failed test with the summary of
16256 failures. Rather, append detailed log afterwards.
16258 2003-06-23 Akim Demaille <akim@epita.fr>
16260 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
16261 always run: output config.log on $at_group_log.

16265 * tests/torture.at (#define header templates): Don't use quotes in

16318 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
16319 (AT_INIT): Support for expected failures.
16321 2003-06-02 Akim Demaille <akim@epita.fr>

16334 is the inverse of localtime.

16338 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
16339 (handle_exec_errors): New function. Work around $! being
16340 altered by WEXITSTATUS.
16341 (xqx, xsystem): Use handle_exec_errors.
16343 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16345 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16346 Do not call `_exit()', simply modify `$?'.
16347 (xsystem): Reset $! before running system, and check it afterward.
16348 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16349 63 for version mismatches.
16351 2003-05-23 Akim Demaille <akim@epita.fr>
16353 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16354 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16355 the middle of a line).
16356 * lib/m4sugar/m4sugar.m4: Likewise.
16357 Remove useless spaces in comments.
16359 2003-05-23 Akim Demaille <akim@epita.fr>
16361 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
16362 exit 63, so that we (or Automake's "missing") can tell the
16363 difference with a plain failure.
16364 * doc/autoconf.texi (Notices): Adjust.

16373 Paul Eggert <eggert@twinsun.com>
16375 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16376 Remove `#include <stdlib.h>' from the list; we should never
16377 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16378 resulting namespace pollution would cause other tests to fail.
16379 Configure scripts run with some older versions of g++ and HP's
16380 aCC would fail due to such an #include. Problems reported by
16381 Matthew Mueller in <http://bugs.debian.org/120704> and by
16383 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16384 In the test, use the test declaration before including <stdlib.h>,
16385 as that's closer to how it'll be used.
16387 2003-05-23 Akim Demaille <akim@epita.fr>
16389 * doc/autoconf.texi (Header Portability): ucred.h.
16392 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16394 Overhaul Autotest's logging: generate separate log files
16395 in testsuite.dir/NNN/testsuite.log, and append them to
16396 testsuite.log instead of re-running the test verbosely.
16398 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16399 file descriptor, write 0 to at_status_file instead of setting
16400 at_status=0, initialize some new variables (at_status_file,
16401 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16402 to rerun the tests, instead append the at_group_log to the
16403 at_suite_log when a test fails.
16404 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16405 with the AS_MESSAGE_LOG_FD redirected to stdout.
16406 (AT_CLEANUP): save the output status in $at_status_file
16407 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16408 its original place.
16409 (AT_CHECK): since tests are run with a redirected stdout,
16410 and used to be re-run in verbose mode, turn some $at_verbose
16411 into echo, and don't redirect the output of testing stdout
16414 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16415 the name of the debugging directory and information about
16418 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

16535 2003-05-06 Akim Demaille <akim@epita.fr>
16537 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16538 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16539 by aclocal.m4 is changed it might require the importing of another
16540 m4 extension file, i.e., aclocal must be run.
16542 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16543 (&parse_args): Use --force with aclocal if required and supported.
16544 (&autoreconf_current_directory): Use &run_aclocal.

16557 2003-04-29 Derek Price <derek@ximbiot.com>
16559 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

16561 (AT_CLEANUP): Add `;' to end of at_help_all.
16562 (AT_INIT): Allow --keywords to be specified more than once. When
16563 grepping $at_help_all for keywords, use the field and keyword
16564 seperators to ensure a complete keyword match. Alter at_prev handling
16565 to support the new --keywords behavior.
16567 2003-04-27 Karl Berry <karl@freefriends.org>
16569 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16570 align better with others. I also made some of the individual
16571 entries on one line, for brevity and to make it easier for me to
16572 sort my dir-example file in the Texinfo distribution :).

16639 header causes problems.
16641 2003-03-28 Akim Demaille <akim@epita.fr>
16643 * tests/torture.at (Configuring subdirectories): Require aclocal
16644 1.4, otherwise the test fails, as it does support configure.ac.

16667 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
16668 obsolete AC_HELP_STRING.
16669 (AC_HELP_STRING): AU_DEFUN to...
16670 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
16671 * tests/m4sh.at (AS_HELP_STRING): New test.
16673 * tests/acgeneral.at: Regenerated.
16675 2003-03-26 Derek Price <derek@ximbiot.com>
16677 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
16678 sense. Verbosify the diversion definitions comment.

16717 Tru64 make in the "target lookup" section.
16718 (Automake): Automake 1.5+ no longer requires special tools to be
16719 present on the developer's host.
16721 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
16723 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
16724 to a shell that can handle redirection or quoting correctly.

16730 * bin/autoupdate.in (BEGIN): Likewise.
16731 * bin/ifnames.in (BEGIN): Likewise.
16733 * bin/ifnames.in: Add final newline to help and version messages.
16735 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16736 to cope with DOS-style absolute paths, when constructing
16739 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16740 When constructing paths with IFS=:, quote the path. If we're
16741 constructing a DOS-style absolute path, we don't want to split it
16744 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
16747 2003-02-25 Pavel Roskin <proski@gnu.org>

16755 2002-09-01 patch by replacing "test -n" with "test -z".
16756 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
16757 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
16759 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
16760 to fix a mismatch between example and discussion.
16762 2003-02-24 Kevin Ryde <user42@zip.com.au>
16764 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16765 format starting with "-".
16767 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16769 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16770 is not portable inside Makefile.
16772 2003-02-20 Akim Demaille <akim@epita.fr>
16774 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
16775 compiler says yeah, but preproc says nope, compiler is right.
16776 Conversely, prompt the reader to send a bug report to the
16777 maintainers of the package, not of Autoconf.
16779 2003-02-20 Klee Dienes <kdienes@apple.com>
16781 * bin/autoreconf.in (autoreconf_current_directory): Properly
16782 handle an empty aclocal.m4.

16787 $ac_prefix_program.
16790 2002-12-23 Paul Eggert <eggert@twinsun.com>
16792 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16793 innocuous variant befor including <limits.h> or <assert.h>. This
16794 works around a bug reported by Albert Chin: HP-UX 11i
16795 (and earlier versions) have a <limits.h> that declares
16796 gettimeofday and many other functions.
16798 2002-12-03 Paul Eggert <eggert@twinsun.com>
16802 * NEWS, configure.ac: Update version.
16804 * doc/fdl.texi: Upgrade to FDL version 1.2.
16806 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16807 nontrivially in main's body, so that f's external declaration is
16808 not optimized away in AIX. This should fix the bug reported by
16810 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16812 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16813 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16814 defined, to support freestanding compilers. This should fix the
16815 bug reported by Momchil Velkov in
16816 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16818 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16819 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
16820 obsolete AC_CHECK_TYPE. The missing empty arg was reported

16822 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
16824 * Makefile.maint (www-gnu): New macro.
16825 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

16831 \(.*\) match is too long and there is something more to be checked.
16832 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
16834 2002-11-15 Akim Demaille <akim@epita.fr>

16850 Update from masters.
16852 2002-11-14 Akim Demaille <akim@epita.fr>
16854 * Makefile.maint: Sync with Bison, i.e.:
16855 (po-check): Scan .l and .y files instead of the
16856 .c and the .h files that they generate. This fixes the bug
16857 reported by Tim Van Holder in:
16858 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16859 Look for N_ as well as for _. Try to avoid matching #define for
16863 2002-11-14 Akim Demaille <akim@epita.fr>
16865 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16866 From Paul Eggert and Albert Chin-A-Young.
16868 2002-11-14 Akim Demaille <akim@epita.fr>
16870 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16871 From Paul Eggert and Albert Chin-A-Young.
16873 2002-11-14 Kevin Ryde <user42@zip.com.au>
16875 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16876 than assigning in main, to avoid HP cc +O3 optimizing it away.
16878 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16880 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16881 option. Process --recheck after parsing all options. Pass -q
16882 option to configure on --recheck.
16883 (AC_OUTPUT): Pass -q from configure to config.status.
16884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16885 arguments to record.
16886 * doc/autoconf.texi (config.status Invocation): Document
16887 config.status -q option.
16889 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16891 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16892 Makefile.in if Makefile.am exists.
16893 (output): Strip `.am' from Makefiles. Don't
16894 output AC_CONFIG_FILES if no Makefiles were found.

16914 Reported by Ezra Peisach.
16916 2002-11-05 Akim Demaille <akim@epita.fr>
16918 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16920 We _have_ to stop using the old compatibility scheme that tried to
16921 avoid useless backslashes because Libtool 1.4.3 contains a
16922 AC_DEFINE([error_t], [int],
16923 [Define to a type to use for \`error_t' if it is not
16924 otherwise available.])
16925 We _have_ to quote the single quote and backslashes with \. The
16926 old compatibility scheme saw that ` was backslashed, and therefore
16927 did not quote the single quote. Hence before this patch, Autoconf
16928 was not compatible with Libtool.
16930 2002-11-04 Paul Eggert <eggert@twinsun.com>
16932 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16949 (&autoreconf): here.
16950 ($help, $make, &parse_args, &autoreconf_current_directory):
16952 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16954 2002-10-31 Bruno Haible <bruno@clisp.org>

16970 2002-10-31 Akim Demaille <akim@epita.fr>
16972 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16973 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16974 Make variable, not a shell variable.
16975 Suggested by Bruno Haible.
16977 2002-10-31 Akim Demaille <akim@epita.fr>
16979 * bin/autom4te.in (load_configuration): Reject #args out of any
16982 2002-10-31 Akim Demaille <akim@epita.fr>
16984 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
16985 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
16986 (_AC_RUN_IFELSE): Use it.
16987 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

16996 Suggested by Tim van Holder.
16998 2002-10-29 Paul Eggert <eggert@twinsun.com>
17000 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
17001 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
17002 Problem reported by Bruno Haible.
17004 2002-10-29 Akim Demaille <akim@epita.fr>
17006 * doc/autoconf.texi (Header Templates): Put also in words what the
17007 pictures says to assist free style readers.
17008 (Customizing autom4te): s/--cache=/--cache /.
17010 2002-10-29 Akim Demaille <akim@epita.fr>
17012 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
17014 sparc_address_test returns void.
17015 Use it with an argument, as prototyped.
17018 2002-10-29 Akim Demaille <akim@epita.fr>
17020 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

17319 Reported by Alexandre Duret-Lutz.
17321 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17382 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17383 aclocal invocation, as Gettext macros might not be visible to

17419 * tests/torture.at (Configuring subdirectories): Be robust to

17582 2002-09-13 Akim Demaille <akim@epita.fr>
17584 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17585 reading config.log when the compiler is rejected.
17586 Suggested by Guido Draheim.
17588 2002-09-13 Akim Demaille <akim@epita.fr>
17590 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17591 (chdir_init) might hang when stat'ing mounted directories.
17592 Reported by Vance Shipley.
17594 2002-09-12 Akim Demaille <akim@epita.fr>
17596 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17599 2002-09-12 Akim Demaille <akim@epita.fr>
17601 * doc/autoconf.texi (Defining Symbols): Present two different
17602 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17603 difference between 1 argument calls, and 2-3 argument calls.
17605 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17607 * doc/autoconf.texi: Review grammar and punctuation.
17609 2002-09-11 Paul Eggert <eggert@twinsun.com>
17611 * doc/autoconf.texi: Fix minor formatting, spelling, and
17613 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17614 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17617 2002-09-11 Akim Demaille <akim@epita.fr>
17619 * doc/autoconf.texi (Questions): Rename as...
17621 (Defining Directories): New.
17623 2002-09-09 Akim Demaille <akim@epita.fr>
17625 * doc/autoconf.texi (Making testsuite Scripts): Update.
17626 Suggested by Nishio Futoshi.
17628 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17630 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17631 plain `@' is wanted.
17633 2002-09-09 Akim Demaille <akim@epita.fr>
17635 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17636 `duplicates', since the algorithm was too naive and could keep
17637 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17638 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17639 Reported by Ralf Corsepius.
17640 * tests/torture.at (Configuring subdirectories): Exercise these
17643 2002-09-09 Akim Demaille <akim@epita.fr>
17645 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17646 looking for a replacement file.
17647 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17648 directory is relative.
17649 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17650 directory definition.
17651 Reported by Andreas Schwab and Jim Meyering.
17653 2002-09-06 Akim Demaille <akim@epita.fr>
17655 * doc/autoconf.texi (Setting Output Variables): Clarify what
17656 precious variables are.
17657 Suggested by Pontus Skoeld.
17659 2002-09-05 Akim Demaille <akim@epita.fr>
17661 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17662 (ifnames, autoscan, autom4te): Since we don't only depend on
17663 configure.ac variables (such as VERSION etc.), but also on prefix
17664 and so forth, depend on Makefile, not configure.ac.
17665 Reported by Alexandre Duret-Lutz.
17666 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17668 2002-09-05 Kevin Ryde <user42@zip.com.au>
17670 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17671 doesn't seem to be confined to ia64, just say "some versions".
17673 2002-09-04 Akim Demaille <akim@epita.fr>
17675 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17677 * Makefile.am (maintainer-clean-local): Remove.
17678 (MAINTAINERCLEANFILES): Remove COPYING.
17680 2002-09-03 Paul Eggert <eggert@twinsun.com>
17682 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17683 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17686 2002-09-03 Akim Demaille <akim@epita.fr>
17688 * configure.ac: Bump to 2.53d.
17689 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17690 as of today, on Automake's team suggestion.
17692 2002-09-03 Akim Demaille <akim@epita.fr>
17696 2002-09-02 Akim Demaille <akim@epita.fr>
17698 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17700 * configure.ac: Disable SITE_MACRO_DIR.
17702 2002-09-02 Jim Meyering <meyering@lucent.com>
17704 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17705 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17706 Also, tweak grammar: s/make sure to/be sure to/.
17708 2002-09-02 Paul Eggert <eggert@twinsun.com>
17710 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17711 directory names are generally preferable to physical names.
17713 2002-09-02 Akim Demaille <akim@epita.fr>
17715 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17716 Reported by Raja R. Harinath.
17717 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17718 * bin/autoupdate.in: Use error instead of die.
17720 2002-09-01 Paul Eggert <eggert@twinsun.com>
17722 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17723 ordinary shell concatenation rather than echo+tr+sed command that
17724 runs afoul of a long-line-related sed bug in Solaris 8.
17726 * bin/autoheader.in (parse_args): --warning -> --warnings.
17728 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17729 stdout, as traditional "ls" does.
17730 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17731 _AC_COMPILER_EXEEXT_O): Likewise.
17732 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17734 * bin/autoconf.as: Add --prepend-include option. This patch was
17735 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17736 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17738 * bin/autoconf.in, configure: Regenerate.
17740 * doc/autoconf.texi (Special Shell Variables): Mention
17741 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17743 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17744 MAILPATH and set PS1, PS2, PS4 to default values, to work
17745 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17746 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17747 the Autoconf documentation specifies; fall back to "unset" only if
17748 this fails. Use a shell for-loop for this rather than an m4 loop,
17749 to shorten the output script.
17751 2002-08-30 Paul Eggert <eggert@twinsun.com>
17753 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17754 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17755 for the CDPATH problem. Document PWD.
17756 (Limitations of Builtins): Document the problem that "cd $foo" and
17757 "ls $foo" may refer to different directories in shells conforming
17758 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17759 example, since the old example is now out of date.
17761 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17762 FOO" and "ls FOO" talk about different directories; this catches
17763 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17766 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17767 of rolling our own unset.
17768 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17769 in practice we needn't worry about CDPATH if unset doesn't work.
17771 * Makefile.in, aclocal.m4, bin/Makefile.in,
17772 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17773 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17774 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17775 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17776 tests/Makefile.in: Regenerate with Automake 1.6.3.
17778 * config/config.guess, config/config.sub, config/mkinstalldirs:
17781 * configure: Regenerate with self.
17783 2002-08-30 Kevin Ryde <user42@zip.com.au>

17793 2002-08-29 Akim Demaille <akim@epita.fr>
17795 * lib/Autom4te/General.pm (&xqx): New.
17796 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17797 hand, which is not portable.
17799 * bin/autom4te.in: Use them.
17800 Use &error instead of die.
17801 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17804 2002-08-17 Paul Eggert <eggert@twinsun.com>
17806 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17807 default list of compilers to try, since it was long ago superseded
17808 by the ksh fc builtin. Suggested by Steven G. Johnson.
17810 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17812 * doc/autoconf.texi (Invoking autom4te): End the option table,
17813 fixing a bug introduced by the previous patch.
17814 (Limitations of Make): Add a 'target lookup' subentry in the
17815 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17817 2002-07-29 Mark D. Roth <roth@feep.net>
17819 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17820 options and use $AUTOM4TE_PATH.
17821 * doc/autoconf.texi: Remove documentation of autom4te
17822 --include-envvar and --site-macro-subdir options and document
17823 use of $AUTOM4TE_PATH.
17824 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17825 arguments from each language section.
17827 2002-07-29 Paul Eggert <eggert@twinsun.com>
17829 * doc/install.texi: Include copyright symbol in copyright notice.
17831 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17833 (AM_MAKEINFOFLAGS): New macro.
17834 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17835 * Makefile.am (INSTALL): Use the new macros.
17836 Use -o rather than --output, since "missing" does not grok --output.
17838 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17840 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17841 comments do not always work. Never trust the exit status of
17844 2002-07-24 Kevin Ryde <user42@zip.com.au>
17846 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17847 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17849 2002-07-23 Paul Eggert <eggert@twinsun.com>
17851 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17852 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17853 apparently treats PATH="nonexistent" as if it contained ".".
17854 Bug reported by Stefan `Sec' Zehl.
17856 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17858 * doc/autoconf.texi (Limitations of Make): Mention the special
17859 handling of the obj/ directory by BSD make.

17905 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
17906 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17907 latter was not run.

18015 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
18017 * bin/autom4te.in ($cache): Don't define using `$me', the name
18018 of the cache should not depend on the name under which autom4te
18021 2002-06-07 Akim Demaille <akim@epita.fr>
18023 * tests/tools.at (autoconf: forbidden tokens, basic)

18064 * tests/mktests.sh (ac_exclude_list): Don't check
18065 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
18067 2002-06-06 Paul Eggert <eggert@twinsun.com>
18069 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
18070 if ln doesn't work.
18072 * doc/autoconf.texi (Configuration Links): Likewise.
18073 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
18075 2002-06-05 Paul Eggert <eggert@twinsun.com>
18077 * config/config.guess, config/config.sub, config/texinfo.tex:

18103 * NEWS, doc/autoconf.texi (Particular Types): Document it.
18104 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
18105 instead of AC_MBSTATE_T, which never existed.

18109 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
18110 version of Autoconf that is discussed.
18112 2002-05-22 Paul Eggert <eggert@twinsun.com>
18114 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
18115 from the default list of compilers to try. Suggested by
18117 * NEWS: Document the above.
18118 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
18120 2002-05-17 Paul Eggert <eggert@twinsun.com>
18122 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
18123 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
18124 This improves on an earlier suggestion by H. Peter Anvin.
18126 2002-05-16 Paul Eggert <eggert@twinsun.com>
18128 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18129 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18130 Both macros now accept an optional source-dir arg.
18131 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18133 * NEWS: Document this.
18134 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18136 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18137 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18138 not for GNU extensions; this undoes part of the 2000-11-03 change,
18139 reverting to 2.13-compatible behavior.
18140 Add new optional argument DIR.
18141 (AC_FUNC_FNMATCH_GNU): New macro.
18143 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
18145 2002-05-08 Paul Eggert <eggert@twinsun.com>
18147 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18148 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18149 and it causes a 'test' syntax error if it fails.
18150 Bug reported by Stephen Gildea.
18152 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18153 If prototypes are supported, use them to check this at compile-time,
18154 instead of trying to check it at run-time. If we must do a run-time
18155 check, assume that setvbuf is standard when cross-compiling, as
18156 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18157 Bug reported by Paul D. Smith.
18159 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18160 argument specifying location of getloadavg.c. This removes a
18161 FIXME. This idea was taken from Jim Meyering's implementation in
18163 * doc/autoconf.texi (Particular Functions): Document this.
18164 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18165 that's what the code does; this fixes a bug reported by
18168 2002-05-03 Akim Demaille <akim@epita.fr>
18170 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18171 autopoint instead of gettextize.
18172 ($uses_alocal): Rename as...
18173 ($uses_aclocal): this.
18174 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18175 Suggested by Bruno Haible.
18177 2002-05-03 Akim Demaille <akim@epita.fr>
18179 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18181 2002-04-29 Paul Eggert <eggert@twinsun.com>
18183 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18184 files to be 1 second older; just set them to be the same time.
18185 Also, sleep 1 second after the first aclocal, to work around
18186 problems with sub-second time stamps on the input files.
18188 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18190 * doc/autoconf.texi: Mention "set -e -x" lossage
18191 under node "Limitations of Builtins".
18193 2002-04-29 Akim Demaille <akim@epita.fr>
18195 * doc/install.texi: Better wording for setting variables when
18197 From Christian Cornelssen.
18199 2002-04-29 Akim Demaille <akim@epita.fr>
18201 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18202 of lack of $LINENO support, then the test will compare the $LINENO
18203 in testsuite vs. the lineno in the test file. This is wrong, of
18205 Be sure to protect it.
18206 Reported by Patrick Welche.
18208 2002-04-25 Akim Demaille <akim@epita.fr>
18210 * doc/autoconf.texi (Obsolete Macros): Typo.
18211 Reported by Vladimir Volovich.
18213 2002-04-25 Akim Demaille <akim@epita.fr>
18215 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18216 than some of the input files, hence, on the second run of aclocal,
18217 if some of its input are younger, make them older.
18218 Suggested by Paul Eggert.
18220 2002-04-25 Akim Demaille <akim@epita.fr>
18222 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18227 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
18228 and ac_subst_vars be sh variables containing the list of
18229 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18231 (_AC_INIT_PREPARE): Use them to log them.
18232 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18233 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18234 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18235 _AC_SUBST_FILES and _AC_SUBST_VARS.
18236 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18238 2002-04-24 Akim Demaille <akim@epita.fr>
18240 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18241 autoheader, so that automake does not complain about a missing
18242 config.h.in that was to be created.
18244 2002-04-23 Akim Demaille <akim@epita.fr>
18246 * bin/autoheader.in (parse_args): --warning takes an argument.
18249 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
18251 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

18296 Minor spelling and grammar fixes.
18298 * doc/autoconf.texi: Follow the outline suggested in the GNU
18299 Sample Texts sections of the Texinfo 4.2 manual. Most
18300 importantly, this makes sure that the copyright notices appear in
18301 all output formats. You probably need Texinfo 4.2 to generate

18328 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
18330 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
18331 from aclocal.m4 too.

18337 2002-04-10 Akim Demaille <akim@epita.fr>
18339 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18340 workaround for ${1+"$@"}.
18341 * doc/autoconf.texi (Shell Substitutions): Explain it.
18342 From Oliver Kiddle and Peter Stephenson.
18344 Have M4sh perform minimal shell sanitizing.
18346 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18348 (_AS_PREPARE): this new macro.
18350 (AS_INIT): Invoke AS_SHELL_SANITIZE.

18353 Adjust Autoconf and Autotest.
18355 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18356 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18357 * lib/autotest/general.m4 (AT_INIT): Likewise.
18358 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18359 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18362 Use this M4sh to generate Autoconf's shell scripts.
18364 * tests/wrapsh.as: New, precursor of wrapsh.in.
18365 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18366 on Autotest and M4sh.
18367 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18368 (wrapsh.in): New target.

18382 2002-04-06 Kevin Ryde <user42@zip.com.au>
18384 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
18385 (Portable Shell): Cross reference to Systemology.
18387 2002-04-05 Akim Demaille <akim@epita.fr>
18389 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
18390 directories when descending in a SUBDIRS.
18391 Reported by Ezra Peisach.
18393 2002-04-04 Andreas Schwab <schwab@suse.de>
18395 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18396 contains no literal separators.
18398 2002-04-03 Akim Demaille <akim@epita.fr>
18400 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18401 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18402 Use dnl, not the KILL diversion.
18404 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18405 (AC_CONFIG_LINKS): here.
18407 Don't use the KILL diversion, as it kills spurious output, which
18408 results in failures being hidden.
18409 Use m4_defn where appropriate.
18410 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18411 after the second argument.
18413 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18414 syntax, as it is provided by M4sugar.

18417 2002-04-03 Andreas Schwab <schwab@suse.de>

18436 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

18439 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18440 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

18454 2002-03-28 Kevin Ryde <user42@zip.com.au>
18456 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18457 to avoid versions of HP C which don't allow that.
18459 2002-03-27 Paul Eggert <eggert@twinsun.com>
18461 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

18473 2002-03-25 Paul Eggert <eggert@twinsun.com>
18475 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18476 as POSIX requires, as it doesn't work with Zsh.
18477 * doc/autoconf.texi (Assignments): Document the problem.
18479 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18481 * doc/autoconf.texi (Limitations of Make): Mention more issue
18482 about VPATH, overriding of macros in sub-makes, and handling of
18485 2002-03-21 Paul Eggert <eggert@twinsun.com>
18487 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18488 problem with here-document buffer boundaries.
18490 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18491 when reinvoking the shell, to work around problems with installers
18492 who put strange things like "cd" commands in their environments.

18514 2002-03-18 Paul Eggert <eggert@twinsun.com>
18516 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18517 (Limitations of Usual Tools): Add mkdir section.
18519 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18520 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18521 back on AS_DIRNAME to compute prefixes otherwise; this is
18522 roughly what mkinstalldirs does. That way, we need not have
18523 our own filename disassembler. The old disassembler did not
18524 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18526 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18527 Create at_test_all by a series of assignments,
18528 not by a single assignment of a long string. The latter causes ksh
18529 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18530 presumably because of a buffer overrun.
18532 2002-03-14 Paul Eggert <eggert@twinsun.com>
18534 * lib/autotest/general.m4 (at_times_skip):
18535 Renamed from at_times. Now a boolean.
18536 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18537 says 'times: not found'.

18630 backward compatibility hooks. Rather, collect them all into...
18631 (Hosts and Cross-Compilation): this new section.
18632 * doc/install.texi (System Type): Ditto.
18633 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

18646 2002-03-04 Akim Demaille <akim@epita.fr>

18649 `foreach' loops immediately evaluate them.
18651 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18652 $*. This is the n-th time I change my mind, but hopefully this is
18655 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18657 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18658 it was only a hack for m4_text_wrap.
18659 (m4_car2): Remove, replaced by...
18661 (_m4_foreach): Adjust.
18662 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

18823 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18824 AUTOTEST_PATH *after* it was set.
18825 Don't put `.' in the PATH: the user should be precise and `./' if
18826 needed. In addition, given that the test suite does some `cd', if
18827 `.' is in the path, the `tested programs' sections will report
18828 programs found in the test suite's directory, while during the
18829 tests (performed in their own directory), these programs are no
18830 longer visible. In other words, the results is confusing and

18907 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18908 and PACKAGE_BUGREPORT from here...
18909 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18911 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18912 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

19056 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
19057 static, to catch errors if the value isn't known at compile-time
19058 and the compiler supports dynamic arrays. Change its name from
19059 `_array_' to `test_array' to avoid potential name clashes.
19060 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
19061 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
19062 better than double. Catch a bug in GCC 2.95.2 x86.
19063 * doc/autoconf.texi (C Compiler): Document the above.
19066 2001-11-13 Akim Demaille <akim@epita.fr>
19068 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
19070 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
19072 2001-11-13 Akim Demaille <akim@epita.fr>
19074 * lib/autotest/general.m4 (AT_INIT): After having run the test
19075 group, go back to the initial directory, not to at_suite_dir.
19077 2001-11-13 Akim Demaille <akim@epita.fr>
19079 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
19080 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
19081 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
19083 (AT_CHECK_CONFIGURE): Use absolute paths.
19084 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
19085 The problem is still the old one: there is no means in M4 (that I
19086 know about) to create a defining macro, because there is no means
19087 to create `$1' etc., therefore, the defining macro ``swallows''
19088 all the arguments meant to the defined macro.
19090 2001-11-13 Akim Demaille <akim@epita.fr>
19092 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
19093 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
19095 * tests/aclocal.m4: Remove, as it is no longer used.
19097 2001-11-13 Akim Demaille <akim@epita.fr>
19099 * lib/autotest/general.m4: Change `tests?' into `groups?' in
19100 variable names when referring to a single test group, or to
19101 `suite' when referring to the whole test suite.
19102 `at_last_test' is removed: m4 compute at_format itself.
19103 (at_stdout, at_stder1, at_stderr): New variables.
19104 (AT_CHECK): Use them.
19106 2001-11-13 Akim Demaille <akim@epita.fr>
19108 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
19110 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19111 Do it as soon as a test fails, don't wait till the end of the test
19113 Don't remove $as_me.[0-9]*, since these files no longer exist.
19115 2001-11-13 Akim Demaille <akim@epita.fr>
19117 * tests/tools.at: Use absolute paths, since we are no longer run
19120 2001-11-13 Akim Demaille <akim@epita.fr>
19122 Now that tests are running in their own private dir, there is no
19123 need to list the files to remove at the end of tests groups.
19125 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19126 (AT_data_files, at_data_files): Remove.
19127 (AT_CLEANUP, AT_DATA): Simplify.
19129 Remove the group dir if !debug && !failed.
19130 * tests/atspecific.m4: Adjust.
19132 2001-11-13 Akim Demaille <akim@epita.fr>
19134 Start a new layout for Autotest: `testsuite' creates
19135 `testsuite.dir' in which the at-check-line etc. files are to be
19136 found, and `testsuite.dir/003' where the test group 3 is run.
19138 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19139 at_check_line_file, at_format, at_test_normalized, at_group_dir
19141 Create the directories.
19142 Use absolute paths for at- files.
19143 (AT_CHECK): Adjust.
19145 2001-11-11 Michael Matz <matz@kde.org>
19147 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19149 (m4_car): Properly quote arguments.
19151 2001-11-13 Akim Demaille <akim@epita.fr>
19153 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19154 with stricter rules on LIBOBJS.
19156 2001-11-12 Paul Eggert <eggert@twinsun.com>
19158 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19159 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19162 2001-11-12 Akim Demaille <akim@epita.fr>
19164 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19166 2001-11-12 Akim Demaille <akim@epita.fr>
19168 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19169 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19170 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19171 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19172 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19173 specify to what the macro should be defined (typically to 1).
19175 2001-11-12 Akim Demaille <akim@epita.fr>
19177 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19180 2001-11-12 Akim Demaille <akim@epita.fr>
19182 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19183 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19184 definition used by Automake where LEX is +/- "${missing} lex" and
19185 `missing' itself contains variables.
19187 2001-11-12 Akim Demaille <akim@epita.fr>
19189 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19190 Now that M4sh pushes BODY, the comments were output at the end of
19193 2001-11-08 Akim Demaille <akim@epita.fr>
19195 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19196 that we can trace macros from aclocal.m4.
19197 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19198 obsoleted, and redirect to the former anyway.
19199 Reported by Ralf Corsepius.
19201 2001-11-08 Akim Demaille <akim@epita.fr>
19203 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19204 processed only if present.
19205 * tests/torture.at (Configuring subdirectories): Use autoreconf
19206 instead of successive calls to autoconf.
19207 Add a nonexistent subdirectory to exercise the patch above.
19208 Reported by Ralf Corsepius.
19210 2001-11-08 Kevin Ryde <user42@zip.com.au>
19212 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
19213 doesn't accept .S files.
19215 2001-11-07 Akim Demaille <akim@epita.fr>
19217 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
19218 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
19219 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
19220 * bin/autom4te.in (warn_forbidden): New.
19221 (handle_output): Use it.
19222 Read m4_pattern_forbid with messages.
19224 2001-11-05 Akim Demaille <akim@epita.fr>
19226 * bin/autom4te.in (--normalize): Remove.
19227 * lib/autom4te.in: Adjust.
19229 2001-11-05 Akim Demaille <akim@epita.fr>
19231 * tests/Makefile.am (testsuite): Rename this target as...
19232 ($(TESTSUITE)): this.
19235 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19237 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19238 the --prefix option, also remove it's argument.
19240 2001-11-05 Akim Demaille <akim@epita.fr>
19242 * doc/autoconf.texi (testsuite Invocation): Update.
19243 (Writing testsuite.at): Update.
19245 2001-11-03 Akim Demaille <akim@epita.fr>
19247 * doc/autoconf.texi: s/@code/@command/ where appropriate.
19249 2001-11-03 Akim Demaille <akim@epita.fr>
19251 * lib/Autom4te/General.pm: (&catfile, &canonfile)
19252 (&file_name_is_absolute): New, wrappers around routines from
19254 Use and export them.
19255 (&find_configure_ac): Optionally take a directory where to look at.
19256 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19258 Default @ARGV to `.', not find_configure_ac.
19259 (&autoreconf): Argument is a directory.
19260 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19261 * doc/autoconf.texi (autoreconf Invocation): Update.
19263 2001-11-03 Akim Demaille <akim@epita.fr>
19265 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19266 (@export_forward_subs): New.
19267 Add basename, dirname, and fileparse.
19269 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19270 Don't look for aclocal flags if we already know aclocal is not
19272 Move aclocal.m4t only if it exists.
19273 Reported by Ezra Peisach.
19275 2001-11-03 Akim Demaille <akim@epita.fr>
19277 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19278 passed on command line, defaulting to ./configure.ac if present.
19279 (&maybe_autoreconf, File::Find): Remove, unused.
19280 (&autoreconf): If autoconf is not used, don't try to trace.
19282 2001-11-02 Akim Demaille <akim@epita.fr>
19284 * configure.ac: Bump to 2.52g.
19286 2001-11-02 Akim Demaille <akim@epita.fr>
19290 2001-11-02 Akim Demaille <akim@epita.fr>
19292 * config/config.guess, config/config.sub, doc/standards.texi:
19293 * config/lispdir.m4: Update from masters.
19294 * configure.ac: Bump to 2.52f.
19296 2001-11-02 Akim Demaille <akim@epita.fr>
19298 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19299 Don't run aclocal when aclocal.m4 is not from aclocal.
19301 Don't run libtoolize and gettextize if --install is not given.
19303 2001-11-01 Paul Eggert <eggert@twinsun.com>
19305 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19306 be invoked before _AS_LINENO_PREPARE.
19307 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19308 than character ranges.
19310 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19311 invoking AS_BASENAME. Set the locale variables to 'C' if
19312 possible, as POSIX requires this to get the traditional
19314 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19316 2001-10-31 Paul Eggert <eggert@twinsun.com>
19318 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19319 with {}, as that triggers a bug in Bash 2.05.
19321 (_AS_LINENO_PREPARE): Use Sed rather than
19322 Awk. Fix the sed prepass to work even if there are multiple
19323 instances of $LINENO on the same line. Do not substitute for
19324 other variables like $LINENOT. Do not check file dates; such a
19325 check is unreliable on sufficiently fast machines, and removing
19326 the check makes the code simpler and more reliable. Check for
19327 output and chmod failures.
19329 * doc/autoconf.texi (Special Shell Variables): Document
19332 2001-10-31 Akim Demaille <akim@epita.fr>
19334 * tests/Makefile.am (atconfig): Remove this target, Automake
19337 2001-10-31 Akim Demaille <akim@epita.fr>
19339 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19340 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19341 provided, while it is optional.
19342 * configure.ac: Adjust.
19344 2001-10-26 Paul Eggert <eggert@twinsun.com>
19346 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19347 lib/Autom4te/Struct.pm:
19348 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19351 * doc/autoconf.texi (Special Shell Variables): Document some
19352 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19354 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19355 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19356 eval $LINENO is not portable in practice.
19358 2001-10-24 Akim Demaille <akim@epita.fr>
19360 * lib/Autom4te/General.pm (backname): New.
19362 2001-10-24 Akim Demaille <akim@epita.fr>
19364 * m4/: Remove, merged into...
19367 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
19369 * doc/autoconf.texi (Shellology): Mention the problems with bash
19370 2.05's use of ANSI quoting in its `set' builtin.
19372 2001-10-22 Paul Eggert <eggert@twinsun.com>
19374 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19375 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19376 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19377 POSIX decided to standardize on the int flavor of strerror_r.
19378 Always do char* test, as there's no reason not to.
19379 Assign to a char* var, to catch strerror_r that returns int*.
19381 * doc/autoconf.texi (Particular Functions):
19382 Document the above changes. Also, document the fact that
19383 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19385 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19387 2001-10-20 Akim Demaille <akim@epita.fr>
19389 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
19390 the executable was missing from the log.
19392 2001-10-20 Akim Demaille <akim@epita.fr>
19394 * lib/Autom4te/General.pm (&update_file): If destination is
19395 unchanged, remove the source.
19396 (&up_to_date_p): Don't be verbose, be debug.
19397 * bin/autoreconf.in: No longer support --m4dir.
19398 (&autoreconf): Display the full path of the configure.ac we are
19400 Trace it only once.
19401 Be sure to honor --force with gettextize.
19402 Always run aclocal.
19403 * doc/autoconf.texi: Adjust.
19405 2001-10-20 Akim Demaille <akim@epita.fr>
19407 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19409 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19410 `intl' is already present, as it refuses unless --force.
19411 (&parse_args): Use -I, --include instead of the old Autoconf
19413 ($localdir, $autoconf_dir): Remove.
19415 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19417 2001-10-19 Jens Petersen <petersen@redhat.com>
19419 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19426 Don't mention `automatically' in addition to `generated'.
19427 * tests/torture.at (#define header templates): Adjust.
19429 2001-10-19 Akim Demaille <akim@epita.fr>
19431 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
19432 comment, explain how to install automatic mode selection.
19435 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
19437 * bin/autoreconf.in (autoreconf): Display the path to the
19438 configure.ac being studied.
19440 2001-10-18 Paul Eggert <eggert@twinsun.com>
19442 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19443 long, to work around a bug in the HP C compiler version HP92453-01
19446 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19447 (AS_BASENAME_EXPR): New macro.
19448 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19449 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19450 and fall back on 'sed' only if the other two fail. This makes
19451 AS_BASENAME act more like AS_DIRNAME.
19452 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19453 contains white space.
19454 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19455 Use AS_DIRNAME, since I think it's now DOS-friendly.
19456 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
19457 Allow "dirname //FOO" to return either / or //, as POSIX allows
19460 2001-10-10 Akim Demaille <akim@epita.fr>
19462 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

19468 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
19469 m4_define, since...
19470 (_AS_ECHO_N): AS_REQUIREs it.
19472 2001-10-10 Akim Demaille <akim@epita.fr>
19474 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

19598 empty, and if we can find a shell that does support LINENO,
19599 then set CONFIG_SHELL to that shell and then re-execute
19600 ourselves with CONFIG_SHELL.
19602 2001-10-05 Paul Eggert <eggert@twinsun.com>
19604 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19605 doesn't exist. Remove *.tmp, as a .tmp file is created during the

19647 compatibility with POSIX shells.

19723 * tests/fortran.at (GNU Fortran 77): there.
19724 * doc/autoconf.texi (autoconf Invocation): Fix the example:
19725 AC_TRY_RUN is about compilation, not shell commands.

19768 Don't compute at_srcdir nor at_top_srcdir.
19770 * tests/tools.at: Hence use top_srcdir.
19772 * tests/Makefile.am, tests/autoconf, tests/autoheader,
19773 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

19887 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

19905 2001-09-19 Akim Demaille <akim@epita.fr>
19907 * lib/autotest/general.m4: Englishoes.
19908 From Tim Van Holder and Alexey Mahotkin.
19910 2001-09-18 Paul Eggert <eggert@twinsun.com>
19912 * doc/autoconf.texi (Common Shell Constructs): New node,
19913 documenting AS_DIRNAME.
19914 (Limitations of Usual Tools): Refer to it when discussing dirname.
19915 Also, update discussion of POSIX standard to reflect latest draft.
19917 * lib/autoconf/c.m4:
19918 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19920 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19921 Do not pass a first argument with leading '-'
19922 to expr, by parenthesizing initial integers that might be negative.
19924 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19925 now merely checks whether it is an error to pass an argument
19928 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19929 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19930 whether it is a (compile-time) error to pass an argument to
19931 getpgrp. This simpler test supports the revised documentation,
19932 and is all that AC_FUNC_GETPGRP's users really need.
19934 2001-09-18 Akim Demaille <akim@epita.fr>
19936 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19948 Add test for AS_BASENAME.
19949 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19950 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19951 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19952 * tests/base.at: Fixed the expected responses. The old ones were
19954 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19955 the documentation claims it should (and how it behaved in 2.13).
19957 2001-09-18 Akim Demaille <akim@epita.fr>
19959 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19960 the AC_CONFIG_COMMANDS invocation.

19964 No longer to be shipped.

19967 * lib/autoconf/status.m4: Adjust.
19968 Use `m4_PACKAGE_STRING'.
19969 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19970 the only optional argument is the name of the test suite.
19971 Expect `package.m4' to define the package signature.
19972 * lib/autom4te.in (Autotest): Add `package.m4?'.
19973 * tests/Makefile.am (package.m4): New.
19974 * tests/suite.at: ifnames is a victim.
19976 2001-09-18 Akim Demaille <akim@epita.fr>
19978 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19979 AC_LIBSOURCE, AC_CONFIG_FILES.
19980 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19981 program version string doesn't match the package's.
19982 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
19985 2001-09-17 Paul Eggert <eggert@twinsun.com>
19987 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19988 Allow expression to return any value that can fit into unsigned long
19989 (not int, as before). Check for output errors.
19991 2001-09-17 Bruno Haible <haible@ilog.fr>
19993 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19994 Always include <stdio.h> and <stdlib.h>. Evaluate
19995 the expression in an extra function before these includes. Call
19996 fprintf "%d" only after ensuring the argument is of type 'int'.
19997 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19999 2001-09-17 Paul Eggert <eggert@twinsun.com>
20001 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
20002 or CFLAGS=-O5. In that case, the linker has a relaxed view of

20359 * tests/atspecific.m4, tests/tools.at: Passing --localdir is

20932 * doc/autoconf.texi (C Compiler Characteristics): Update
20933 documentation for AC_C_BIGENDIAN.
20935 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20937 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20938 magic values from an object file when cross-compiling.
20939 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20941 2001-08-10 Akim Demaille <akim@epita.fr>
20943 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20945 Suggested by Russ Allbery.
20947 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20949 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20950 current $prefix to the sub-configures.
20952 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20954 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20955 extension (needed on BeOS). Reported by Guido van Rossum.
20957 2001-08-09 Akim Demaille <akim@epita.fr>
20959 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20961 2001-08-07 Akim Demaille <akim@epita.fr>
20963 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20965 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20966 No need to remove the files before and after the each test, before
20967 each test and at the end of the suite is enough.
20968 Display only the children `times', not the shell's.
20969 If the test failed or was skipped, at-times is not available.
20971 2001-08-07 Akim Demaille <akim@epita.fr>
20973 Always produce testsuite.log, including when there are no
20974 failures. This helps getting information on skipped tests, and
20975 duration of the tests. Err, implement the latter btw.
20977 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20978 Dump information on the first run of each test.
20979 (AT_CLEANUP): Create `at-times' containing the duration of the
20982 2001-08-07 Akim Demaille <akim@epita.fr>
20984 The use of `dumpstat' revealed that `len' was used although it
20985 should not. m4_text_wrap was using it, but in the Autoconf world
20986 where it is legal. Hence (i) test M4sh in its own world, not
20987 Autoconf's, and (ii), ahem, fix the bug :)
20989 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20990 does not like `' instead of [].
20991 (AT_INIT): Forbid `^_?AT_'.
20992 And don't output such tokens.
20993 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20994 `script.as', and `autom4te.cache'.
20995 Remove `empty' and `macro' which are no longer used.
20996 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20997 * tests/m4sugar.at: Use it.

21019 Don't rely on M4sugar outputting the patterns in files, since we

21024 * bin/autom4te.in (@Request::includes): Remove, unused.

21033 2001-08-04 Akim Demaille <akim@epita.fr>
21035 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
21036 autoconf', i.e., in addition to caching traces, cache the output.

21039 (Request::id): this.
21040 ($cache, $icache, $tcache, $ocache): New.

21050 (&parse_args, &print_usage): -f, --force is a new option.

21052 (&parse_args): The first file only can be frozen.
21054 2001-08-04 Akim Demaille <akim@epita.fr>
21056 Don't let autom4te compute the `include' traces several times:
21057 first check that the trace cache file is up to date, and then
21058 compare its timestamp with that of the output.
21060 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
21061 the preamble. Don't require 5.005 as Autom4te::General does it,
21062 and better yet (use `use', not `require'!).
21063 * lib/Autom4te/Struct.pm: Rename the last occurrences of
21064 Class::Struct as Autom4te::Struct.
21065 * lib/Autom4te/General.pm (File::stat): Use it.
