501 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
502 &s;" test into the main program, as C99 might plausibly be
503 interpreted as not requiring support for this construction in
504 static initializers. Remove the "#if defined __xlc__" stuff, as
505 the bug is not present in recent xlc implementations, and they
506 reject the test for other (valid) reasons. People using ancient
507 xlc versions, if any, are suggested to update to fixed versions.

2140 Work around DJGPP shell function return bug with command substitutions.
2141 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
2142 shell function which also contains a command substitution causes
2143 the shell to barf. For more details and a fix see:
2144 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
2145 Possible workaround include putting the `return' in a subshell
2146 or calling another function to set the status.
2147 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE_BODY)

2171 2009-09-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2173 DJGPP fix: remove both conftest and conftest.exe.
2174 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
2175 and both `conftest' and `conftest.exe' with `-o conftest', but not
2176 with `-o conftest.exe'.
2177 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
2178 `conftest' without $ac_exeext suffix.
2180 DJGPP fix: do not try to source /dev/null as cache or site file.
2181 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
2182 load the cache or site file if it is `/dev/null', as DJGPP treats
2183 it as a regular file, but the shell then warns about it later.

2203 Improve autotest testsuite summary message.
2204 * lib/autotest/general.m4 (AT_INIT): Hint at the toplevel log

7040 Cover more potentially problemtic file names. Use the new
7043 Properly handle funny file names for headers in config.status.
7044 The test suite did not cover this bug because the code was not
7045 quoting properly the arguments of `rm -f' (which "fails" silently)
7046 as well as the arguments of `diff' (whose output was redirected to
7047 /dev/null so we couldn't see its error message).
7048 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
7049 file names passed to `rm' and `diff'.
7050 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

7160 not just when atconfig was located.
7162 Add 'testsuite -C dir'.
7163 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
7165 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
7167 <DEFAULTS>: Delay computation of variables based on $at_dir...
7168 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
7169 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
7170 <PARSE_ARGS>: Parse new option.
7171 <HELP_TUNING>: Document it.
7172 * tests/autotest.at (Choosing where testsuite is run): New test
7174 (Keywords and ranges): Add test for missing -k argument.
7175 * NEWS: Document this.
7176 * doc/autoconf.texi (testsuite Invocation): Likewise.
7178 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7180 * build-aux/config.guess, build-aux/config.sub,
7181 build-aux/texinfo.tex: Sync from gnulib.
7182 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
7185 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7187 * doc/autoconf.texi (Particular Programs): Do not mention the
7188 Autoconf version in which the AC_PROG_INSTALL change was done.
7189 Suggested by Paul Eggert.
7191 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7193 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
7194 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
7195 mode, we change to the source directory, also set $ac_pwd so we
7196 do not go back to the build tree for the next config subdir.
7197 * tests/torture.at (Deep Package): Extend test to contain two
7198 config subdirs on the top level.
7200 Fix parallel `maintainer-check'.
7201 * Makefile.am (maintainer-check-tests): Depend on `all'.
7202 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
7203 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
7205 (maintainer-check): Serialize the testsuite runs.

7231 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
7232 check_SCRIPTS. Building the wrappers for `all' allows help2man
7233 to use them for the manpages.
7234 Report by Benoit Sigoure.
7236 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
7238 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7240 Fix some write failure cases in Autotest.

7252 (m4_require): Use m4_do, not m4_join.
7254 Fix some whitespace tests on cygwin.
7255 * tests/tools.at (autom4te and whitespace in file names): Restore
7256 font-lock. Create $TMPDIR before it might be used.
7258 Fix spurious testsuite failure with M4 1.4.11.
7259 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
7261 Optimize AC_REQUIRE.
7262 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7263 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7264 (m4_require): Avoid extra macro calls.
7266 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7268 * tests/torture.at (srcdir): Fix quoting.
7270 Do not pass top_srcdir to configure scripts in testsuite.
7271 * tests/autotest.at (srcdir propagation): Copy install-sh to
7273 (my only test): Drop setting of `top_srcdir'.
7274 * tests/base.at (Input/Output): Likewise.
7275 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
7276 config.guess, and config.sub to test source tree.
7277 Drop AC_CONFIG_AUX_DIR setting.
7278 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
7279 * tests/torture.at (Substitute a 2000-byte string): Drop
7280 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
7281 (Substitute a newline, datarootdir workaround): Likewise.
7282 (Define a newline): Adjust for linenumber changes in configure.ac.
7283 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
7285 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
7286 if `pwd` contains whitespace.
7288 Quote $abs_top_srcdir in tests.
7289 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
7290 * tests/tools.at (Syntax of the shell scripts): Likewise.
7292 * tests/m4sh.at (LINENO): Quote $0.
7294 Fix testsuite program wrapper for whitespace in `pwd`.
7295 The problem here is that the usual mantra is that command
7296 variables can contain arguments, thus we cannot just escape
7297 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
7298 $top_builddir/tests directory early in $PATH, so that the
7299 wrappers are found by their plain name.
7300 * tests/wrapper.as: Put $testdir early in $PATH.
7301 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
7303 Proper config.status --file/--header and $srcdir escaping.
7304 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
7305 characters in $ac_file_inputs.
7306 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs

7309 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
7311 Fix Autotest for whitespace in `pwd`.
7312 * lib/autotest/general.m4 (AT_INIT)
7313 <at_func_create_debugging_script, Driver Loop>:
7314 Quote $at_group_dir.
7315 * tests/autotest.at (whitespace in absolute testdir): New test.
7317 * lib/autom4te.in: Quote @datadir@.
7319 Proper file name escaping in Autoconf programs and Perl modules.
7320 This includes escaping of characters special to the shell
7321 as well as special to Perl, e.g., leading `<' or `>'.
7322 For example, when $file starts with `>', `open ">$file"'
7323 wrongly tries to append to a different file.
7324 * bin/autoconf.as: Fix quoting for autom4te options.
7325 * lib/Autom4te/General.pm (shell_quote): New function, taken
7326 from coreutils, written by Jim Meyering.
7328 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
7330 * bin/autoreconf.in (parse_args): Likewise.

7332 * bin/autoupdate.in (main): Likewise.
7333 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
7334 * bin/ifnames.in: Likewise, XFile usage fixes.
7335 * tests/tools.at (autom4te and whitespace in file names): Extend
7336 test. Test twice, with special characters allowed on w32, and the
7337 rest. Test leading and trailing whitespace, for `open_quote'.
7338 (autotools and whitespace in file names): New, analogous test.
7339 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
7340 by Russ Allbery and Eric Blake.
7343 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
7344 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
7345 * lib/Autom4te/FileUtils.pm (open_quote): New function.
7346 (update_file, contents): Use it.
7348 * Makefile.am (autom4te-update): Rewrite for git.
7350 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7352 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
7354 Fix copyright years.
7355 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
7356 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
7358 2007-12-04 Eric Blake <ebb9@byu.net>
7360 Manually resync with gnulib, since 'make cvs-update' no longer works.

7364 When using older automake, don't downgrade build-aux/texinfo.tex.
7365 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
7366 * doc/Makefile.am (TEXINFO_TEX): Add.
7368 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
7370 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
7371 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
7372 #undef as this runs afoul of our new way of creating config.h.
7373 Problem reported by Jim Meyering in
7374 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
7376 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7378 Fix autom4te for unusual characters in input file names.
7379 * bin/autom4te.in (files_to_options): Quote active characters
7381 * tests/tools.at (autom4te and white space in file names):
7384 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
7385 Document that Tru64 awk always splits $0.
7387 2007-11-24 Stepan Kasal <kasal@ucw.cz>
7389 * lib/autotest/general.m4 (AT_INIT): Do not extract the
7390 `#AT_STOP_...' line at the end of each test.
7392 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7394 * lib/autotest/general.m4 (AT_INIT): For awk line number
7395 extraction script, ensure `$at_group' has a defined value
7396 even for the empty set, and properly quote its usage inside
7399 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7401 * doc/autoconf.texi (Shell Functions): New chapter. Document
7402 IRIX sh $0 issue in functions, move content from ...
7403 (Portable Shell): ... here.
7404 (Shell Script Compiler): Note that shell functions are not
7405 totally unportable any more.
7407 2007-11-22 Stepan Kasal <kasal@ucw.cz>
7408 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7410 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
7411 extracting the line numbers of the last needed test.
7413 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7415 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7418 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7420 Fix IRIX testsuite debugging failures: $0 in functions.
7421 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7422 Do not use $0 inside a function, as IRIX sh will set that to the
7423 function name rather than the script invocation name.
7425 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7426 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7428 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7429 to extract test scripts.
7430 (AT_INIT): Extract and cache test script line numbers.
7432 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7434 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7435 subsequent fixups; the awk -> here-document conversion trashes
7436 performance too much with AIX sh.
7438 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7440 * tests/local.at: Do not test m4, perl with AT_TESTED.
7442 Diagnose and guard against write errors dealing with config.status.
7443 The general idea is this: all write failures from `configure'
7444 writing `config.status' are indicated by $ac_write_error, which
7445 is only checked at the end. This is safe because config.status
7446 code is not executed before the file is complete. Other write
7447 failures, be they inside config.status, or in sub shell/awk
7448 scripts spawned from configure or config.status, typically need
7449 earlier checking, as their results are used right afterwards.
7450 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7451 before writing config.status, check afterwards.
7452 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7453 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7454 Set `ac_write_error' for write failures to config.status. Barf
7455 upon write failures to temporary files.
7456 Adjust note about closing and reopening the here-document.
7457 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7458 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7459 reopening the here-document.
7460 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7461 Ensure `ac_write_error' does not escape into config.status.
7462 Also, add a couple of code paths not yet exercised in the test
7463 suite: a config file with input from stdin, and a config header
7465 Suggestion for catching write errors by Bruno Haible.
7467 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7469 Avoid error with Tru64 awk and testsuite lines with many words.
7470 * lib/autotest/general.m4 (AT_INIT): In the awk script that

7483 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7485 AC_*_TOOL does not canonicalize the prefix
7486 * doc/autoconf.texi (Generic Programs): Do not say that
7487 the *_TOOL macros canonicalize, they simply use the `host_alias'.

7491 Diagnose write errors in config.status instantiations.
7492 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7493 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7495 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7496 Extend test to also check for some write error failures, using...
7497 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7498 Report by Bruno Haible.
7501 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

7507 Add witness macro for @top_build_prefix@ substitution.
7508 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
7509 (_AC_OUTPUT_FILE): Mention it here.
7511 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7512 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7514 * lib/autotest/general.m4 (at_func_test): Remove.
7515 (AT_INIT): Pre-extract test groups into separate files.
7516 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7517 Remove at-test-source files together with the $at_group_dir.
7518 * tests/autotest.at (Long test source lines): New test.
7520 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7522 Shell functions and variables may share a namespace.
7523 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
7526 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
7528 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7531 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7533 * lib/autoconf/status.m4: Fix a couple of comment typos.
7535 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7537 2007-11-13 Jim Meyering <meyering@redhat.com>
7539 Clean up the rule to create "expr".
7540 * tests/Makefile.am (expr): Don't redirect directly to target.
7541 Redirect just once, not for each echo statement.
7542 Use $@, not literal "expr".
7544 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7546 Don't worry about preprocessor when testing long long.
7547 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7548 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7549 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7550 These no longer check for preprocessor flaws.
7551 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7552 Do not check for preprocessor flaws.
7554 2007-11-13 Jim Meyering <meyering@redhat.com>
7556 Adapt dependencies, now that a version change doesn't modify configure.ac
7557 * GNUmakefile: Remove "make clean" kludge.
7558 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7560 Don't redirect directly to target.
7561 Use $@, not literal "version.m4".
7563 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7565 * doc/autoconf.texi (Making testsuite Scripts): Document
7566 ":;{" shorthand as in previous patch.
7568 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7570 * doc/autoconf.texi (Limitations of Builtins): Document problem
7571 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7573 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7574 Use ":;{" shorthand.
7575 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7577 2007-11-12 Jim Meyering <meyering@redhat.com>
7579 Add more non-srcdir build support.
7580 * GNUmakefile (dummy): Split a long line.
7581 Add -v option to autoreconf invocation.
7583 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7584 * GNUmakefile (dummy): Remove INSTALL.
7586 Remove racy commands to build scripts in bin/ and tests/.
7587 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7588 are guaranteed to be built, remove the rules that tried to build
7589 them. Before, with a parallel build, these rules could lead to
7590 two processes writing tests/wrapper.in concurrently.
7592 Build in man/ only *after* building in bin/ and tests/.
7593 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7594 in both bin/ and tests/.
7596 Accommodate non-srcdir build-from-checkout.
7597 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7598 Use git's --git-dir=$srcdir/.git option.
7599 Add quotes, in case tarball_version_file contains shell meta-characters.
7600 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7601 * configure.ac: Pass "." to git-version-gen.
7603 Avoid spurious test failures due to version skew.
7604 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7606 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7608 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7609 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7610 Remove conftest.dSYM directory.
7611 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7612 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7613 Remove `conftest.*' recursively.
7614 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7615 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7617 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7619 Report and analysis by Jeff Squyres and Peter O'Gorman.
7621 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7623 Fix typos in variable names.
7624 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7626 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7628 Document that $((expression)) is not portable.
7629 * doc/autoconf.texi (Shell Substitutions): Here.
7631 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7633 Ignore configure --help* errors due to LINENO-impaired shells.
7634 * tests/torture.at (Configuring subdirectories, Deep Package):
7635 In the --help* tests in read-only trees, make `.' temporarily
7636 writable again for the `stderr' file, and ignore errors due to
7637 the attempt to write configure.lineno.
7638 Report by Patrick Welche.
7640 2007-11-10 Jim Meyering <meyering@redhat.com>
7642 Generate package.m4 in build-dir, not srcdir.
7643 * tests/Makefile.am (package.m4): Adjust target.
7644 Don't redirect directly to $@.
7645 (CLEANFILES): Add package.m4.
7646 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7648 When running $(AUTOTEST), search "." before searching $(srcdir).
7650 Avoid a race condition that would make parallel "distclean" fail.
7651 * tests/Makefile.am (distclean-generic): Replace the default,
7652 automake-provided rule with an identical one, but with an additional
7653 dependency on distclean-local. Simply adding the dependency would
7654 cause automake not to emit the rule at all.
7655 * BUGS: Building with -jN works, now.
7657 Distribute git-version-gen.
7658 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7659 since GNUmakefile is distributed, and requires it for dist* rules.
7661 Remove two more generated files from version control.
7662 * INSTALL: Remove generated file.
7663 * lib/autoscan/autoscan.list: Remove generated file.
7665 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7667 * GNUmakefile (PATH): Remove stray apostrophes; they become
7668 part of PATH, which isn't wanted here.
7670 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7672 New config files output variable `top_build_prefix'.
7673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7675 * doc/autoconf.texi (Preset Output Variables): Document it.
7677 Report by Bob Friesenhahn.
7679 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7680 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7681 function, to parametrize arithmetic with expr vs. the shell.
7682 Use it where possible.
7683 Suggestion by Benoit Sigoure.
7685 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7687 Adjust the documentation of autotest WRT atlocal.
7688 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7689 when using Automake, to write a rule to produce atlocal, since it's
7690 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7691 distributed, not atconfig.in.
7693 2007-11-04 Eric Blake <ebb9@byu.net>
7695 Update list information.
7696 * README: Mention new autoconf-commit list.
7697 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7699 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7701 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7703 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7705 * build-aux/.gitignore: Ignore mkinstalldirs.
7707 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7709 2007-11-03 Jim Meyering <meyering@redhat.com>
7711 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7712 * build-aux/git-version-gen: This syncs from coreutils.
7714 Adjust the build procedure so "make check" works reliably.
7715 * README-hacking: Include an extra step between "make" and
7716 "make check" to ensure that the latter passes.
7718 Use just-built tools, when possible.
7719 * GNUmakefile (PATH): Set and export here, ...
7720 (dummy): ... rather than here.
7722 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7723 and Andreas Schwab <schwab@suse.de>
7725 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7728 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7730 * configure.ac (AC_PREREQ): Require version 2.60, for
7731 AC_PROG_SED, AC_PROG_GREP.
7733 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7734 and Jim Meyering <meyering@redhat.com>
7735 and Andreas Schwab <schwab@suse.de>
7736 and Eric Blake <ebb9@byu.net>
7738 Document a bug in GNU Bash with compound commands and redirections.
7739 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7740 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7743 2007-11-03 Eric Blake <ebb9@byu.net>
7745 Support m4 1.4.5 in testsuite.
7746 * tests/torture.at (Define a newline): Exclude line numbers in
7748 Reported by Ralf Wildenhues.
7750 2007-11-03 Jim Meyering <meyering@redhat.com>
7752 Remove automake-provided files from version control.
7753 * build-aux/elisp-comp: Remove file.
7754 * build-aux/install-sh: Remove file.
7755 * build-aux/missing: Remove file.
7756 * build-aux/mdate-sh: Remove file.
7757 * build-aux/.gitignore: New file.
7758 Suggestion from Ralf Wildenhues.
7760 2007-11-03 Eric Blake <ebb9@byu.net>
7762 Adjust version comparison to account for git snapshot numbers.
7763 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7764 component separator.
7765 * doc/autoconf.texi (Number processing Macros)
7766 <m4_version_compare>: Document this change.
7767 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7769 2007-10-30 Bruno Haible <bruno@clisp.org>
7771 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7772 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7773 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7774 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7775 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7776 Suggested by Paul Eggert.
7778 2007-10-28 Jim Meyering <meyering@redhat.com>
7780 * README-hacking: Autoconf, Automake, and Perl are required to build.
7781 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7783 2007-10-28 Jim Meyering <meyering@redhat.com>
7785 README-hacking: Recommend running autoreconf -vi.
7786 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7787 so that we use just-built tools when they're available.
7788 Suggestions from Ralf Wildenhues.
7790 2007-10-28 Jim Meyering <meyering@redhat.com>
7792 Make inter-release --version output more useful.
7794 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7795 which indicates that it is built using the 19th change set
7796 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7797 is a prefix of the commit SHA1.
7798 * build-aux/git-version-gen: New file.
7799 * configure.ac: Run it to set the version.
7800 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7801 * Makefile.am (dist-hook): Arrange so that .version appears only
7802 in distribution tarballs, never in a checked-out repository.
7803 * .gitignore: Add .version here, too. Just in case.
7804 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7805 not configure.ac, now that the version number changes automatically.
7807 Ensure that $(VERSION) is up to date for dist-related targets.
7808 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7809 git-version-gen doesn't match $(VERSION), but only for dist targets.
7811 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7813 Fix `Deep Package' failure with a configure script early in PATH
7814 * tests/torture.at (Deep Package): Add `.' early in PATH.

7843 problem reported by Bruno Haible in
7844 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
7846 2007-10-22 Eric Blake <ebb9@byu.net>
7848 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7851 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7853 Don't check for bug in HP-UX 11.00 cpp.
7854 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7855 Use -1ull rather than -1u, since that causes problems with gnulib; see
7856 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
7858 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7874 escaping of backslash in here-documents.
7876 Fix `Deep Package' test failure on FreeBSD.
7877 * tests/torture.at (Deep Package): Do not add `.' to $PATH
7878 unnecessarily. Do not try running `/bin/sh configure' with a
7879 configure script to be found in $PATH, if the shell does not do
7880 this resolution. Fixes test failure on FreeBSD.
7882 Fix config header generation with AIX awk.
7883 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7884 script, use helper array D_is_set, as `" 0"' does not evaluate
7885 to true for AIX awk.
7887 2007-10-21 Eric Blake <ebb9@byu.net>

7922 * lib/autotest/general.m4 (BANNERS): New named diversion.
7923 (TESTS_END): Diversion no longer used.
7924 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
7925 shell function, which prints only as needed, using an associative
7926 array of banner text from a special diversion.
7927 <PARSE_ARGS_END>: No longer need awk to find banners.
7928 <TESTS>: Banners are no longer processed by main driver loop, so
7929 we no longer need case statement.
7930 (AT_BANNER): Rewrite to populate new diversion.
7931 (AT_SETUP): Each test invokes its own banner. No output is needed
7932 to the TESTS diversion.

8960 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
8961 choice, since that's what we do with --enable-largefile etc.
8962 Redo indenting and assignments to simplify things a bit, and make
8963 the parens work with Emacs.
8965 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo

9048 * doc/autoconf.texi (Particular Programs): Typo
9049 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
9051 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
9053 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
9054 'configure' will fail if the shell lacks proper support for shell

9065 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
9066 for a.* when searching for executables, as this prevents users
9067 from having files like a.c. Problem reported by Ralf Wildenhues in:

9079 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
9080 AC_CHECK_TYPE, AC_CHECK_TYPES.
9081 * doc/autoconf.texi (Generic types): C types must be type-names
9082 (the C terminology), not type-ids (the C++ term). C++ types
9083 must not be anonymous.
9084 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
9085 for C++; this drops support for anonymous struct and union types,
9086 which were problematic anyway.

9103 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
9104 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
9105 with objects too. Document the restrictions on its use.
9106 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
9107 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
9108 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
9109 works but the latter doesn't, then it's a valid type.
9110 This lets people use function types and so forth.
9111 For C++ there doesn't seem to be a simple solution, so leave it alone.
9112 (AC_CHECK_SIZEOF): Allow argument to be a variable.
9113 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
9114 AC_CHECK_TYPE; that wasn't documented or necessary.
9116 2007-04-11 Stepan Kasal <kasal@ucw.cz>
9118 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

9137 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
9139 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
9140 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
9141 default still has the problem. Problem reported by Bruce Korb.

9162 checks for unsigned long long int.
9164 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
9166 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
9167 nonstandard grep R.E. escape sequences.
9169 2007-03-17 Jim Meyering <jim@meyering.net>
9171 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
9172 (Limitations of Usual Tools): Also list \< and \>, and mention that
9173 HP-UX's grep, like the one from Solaris, does not support that syntax.
9175 2007-03-09 Stepan Kasal <kasal@ucw.cz>
9177 * doc/autoconf.texi (Specifying Names): `--host' does not
9178 change the build type.

9216 status of rm so we know when it failed.
9217 If cleaning of test dir failed before running the test, warn.
9218 Output the line separator in verbose mode before the warning
9219 to make clear the warning belongs to the following test.

9246 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
9247 input from /dev/null in awk test, so even Solaris /usr/bin/awk

9284 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
9285 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
9286 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
9287 substitution will still be done by the special code.
9288 Report by Jim Meyering.

9311 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
9312 early on the reader side, drop stderr of the input to avoid
9313 `broken pipe' error output; this may happen even with shell
9314 builtin `echo' of some bash versions. Reports by Ian Macdonald
9315 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
9317 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9331 * doc/autoconf.texi (Signed Overflow Examples): Give more
9332 discussion about the allow_superuser_privileges example,
9333 and change it a bit to make things clearer.
9334 (Optimization and Wraparound): Clarify whether the compiler
9335 will generate an infinite loop for the example derived from
9336 Autoconf's mktime test.
9337 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
9338 Also, clarify unsigned multiplication overflow.
9340 2007-01-04 Eric Blake <ebb9@byu.net>
9342 * bin/Makefile.am (RELEASE_YEAR): New macro.
9343 (edit): Use it to supply correct copyright year to scripts.
9344 * bin/autoconf.as (version): Use it.
9345 * bin/autoheader.in ($version): Likewise.
9346 * bin/autom4te.in ($version): Likewise.

9352 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
9354 * doc/autoconf.texi (Integer Overflow): Revised based on today's
9355 feedback. The most important changes document what happens when
9356 you convert an out-of-range value to a signed integer type, and
9357 say that (sum < a) != (b < 0) reliably detects overflow when sum =
9360 * doc/autoconf.texi (Integer Overflow): Greatly expand and
9361 rewrite, taking notions from the recent discussion on the gcc and
9362 autoconf mailing lists; please see
9363 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
9364 and follow the many links.
9365 (Integer Overflow Basics, Signed Overflow Examples):

9367 (Signed Integer Division): New sections.
9369 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
9371 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
9372 preprocessor macro arguments in traced name.
9373 * doc/autoconf.texi (Defining symbols): Document longstanding
9374 support for AC_DEFINE-ing macros with arguments, and document
9375 behavior when the same variable has multiple AC_DEFINEs.
9376 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
9377 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
9378 macros directly, giving much shorter and simpler code.
9380 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
9382 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
9383 space before "$ac_configure_args" to prevent a 'config.status
9384 --recheck' failure if ac_configure_args doesn't contain a leading
9385 space. This works around a problem with the XEmacs configure.ac,
9386 which uses the (undocumented) ac_configure_args variable
9387 inconsistently with Autoconf.
9389 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
9391 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
9392 Include <limits.h>, and use its INT_MAX to rewrite the
9393 j loop so that it does not overflow 'int'. Problem reported by
9395 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
9396 Play it safe by shifting left by 1 rather than multiplying by 2,
9397 as GCC is less likely to optimize this away when the value
9398 is signed (when it assumes overflow leads to undefined behavior).
9399 Also, don't assume time_t uses two's complement.
9401 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9403 * tests/torture.at (Substitute a 2000-byte string): Avoid using
9404 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
9405 dumps core on it. Report by Tim Rice.

9422 * doc/autoconf.texi (Option Checking): Renamed from
9423 (Configure Option Checking). Tighten up the wording a bit.
9424 (External Software, Package Options): Cross-reference to Option
9425 Checking, and use this to shorten our section.
9426 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9427 "$x" to test "x$foo" != x.
9428 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9429 Don't warn if $enable_option_checking is "no".
9430 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9431 ac_unrecognized_opts to the empty string.
9432 Don't echo the unrecognized opts, as this might mishandle
9433 backslashes or leading -.
9434 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9435 usage next to the other --disable-FEATURE options in the
9438 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9440 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9441 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9442 Print warning for unrecognized --with and --enable options
9443 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9444 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9445 Disable option checking when subdirs are configured.
9446 (AC_OUTPUT): If warnings are enabled, print warning about
9447 unrecognized --with and --enable options at the end of
9448 the configure output (as well as at the beginning).
9449 * doc/autoconf.texi (Option Checking): New node.
9450 Document new option warning functionality.
9452 2006-12-16 Eric Blake <ebb9@byu.net>
9454 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9455 * NEWS: Start news for current version.
9457 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9459 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9460 Define HAVE_GETMNTENT to 1, not to the empty string.
9461 Problem originally reported by Jochen Friedrich in
9462 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9464 This change prompted by a problem report by Andrey Simonenko in
9465 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9466 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9467 object-like macros only, in the traditional portable character
9469 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9470 Warn about attempts to define things that are not identifiers.
9471 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9472 awful hack that AC_DEFINEd macro names containing parentheses.
9474 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9476 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9477 too drastic, even if Texinfo in theory requires it for info mode.
9479 (config.status Invocation): Renamed back from Recreating a
9481 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9482 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9484 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9486 * NEWS: Version 2.61a.
9488 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9489 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9491 * NEWS: Document changes with echo and printf, and the lack
9492 of limits on the total size of multi-line values of substituted
9493 variables, and the AC_FUNC_FSEEKO fix.
9495 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9497 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9498 Writing configure.ac.
9499 (Autoconf Input Layout): Renamed from configure.ac Layout.
9500 (Recreating a Configuration): Renamed from config.status Invocation.
9501 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9502 (acconfig Header): Renamed from acconfig.h.
9503 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9504 (Writing Testsuites): Renamed from Writing testsuite.at.
9505 (Autom4te Cache): Renamed from autom4te.cache.
9507 * BUGS: Remove mention of VPATH problem, since it's now documented
9508 not to be a bug in the Autoconf build procedure itself, but rather
9509 a problem with the proprietary `make' programs.
9511 * doc/autoconf.texi (Build Directories): Add a cross reference
9514 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9515 * doc/standards.texi: Sync from gnulib.
9517 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9518 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9519 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9520 generated automatically.
9522 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9524 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9525 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9526 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9528 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9530 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9531 `CEOF$ac_eof' special marker, the awk script cannot contain a
9532 line matching `^CEOF', so this is not needed any more.
9533 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9534 special marker in the test.
9536 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9538 * tests/tools.at (autom4te preselections): Use `find -newer';
9539 remove one of the sleeps.
9541 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9542 more readable, using ...
9543 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9545 * doc/autoconf.texi (autoheader Invocation): Do not double-
9546 quote the parameter of `AH_BOTTOM' in the example.
9548 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9550 * doc/autoconf.texi (Configuration Headers): Remove the
9551 example with multiple input files.
9552 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9553 multiple input files.
9555 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9557 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9558 creating the awk substitution script, handle one input line at a
9559 time, so that the maximum length of a substituted (multi-line)
9560 value is not limited by the size of the sed pattern space.
9561 The trade-off is a slightly repetitive sed script.
9562 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9563 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9564 * tests/torture.at (Substitute a 2000-byte string): Increase the
9565 test with several long lines, they should not be caught by sed
9568 * tests/tools.at (autom4te preselections): New test, to flag
9569 entries missing from autom4te.cfg.
9570 Report by David Byron <dbyron@hheld.com>.
9572 * tests/torture.at (Substitute a 2000-byte string): Actually use
9573 AC_PROG_AWK, so the last change works as intended.
9574 (Substitute and define special characters): Likewise.
9575 (Substitute a newline): Likewise.
9577 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9578 instead of `awk' consistently.
9579 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9580 * tests/torture.at (Torturing config.status): Test both the
9581 result of AC_PROG_AWK and plain awk.
9582 (Substitute a 2000-byte string): Likewise.
9583 (Substitute and define special characters): Likewise.
9584 (Substitute a newline): Likewise.
9586 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9588 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9589 can be assigned to a function pointer. Problem reported by
9590 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9591 part of a patch by Ralf Wildenhues in that same bug report.
9593 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9595 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9596 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9598 2006-12-01 Eric Blake <ebb9@byu.net>
9600 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9601 cross-compiling from cygwin to mingw.
9602 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9603 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9604 to lib/autoconf/c.m4.
9606 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9608 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9609 string for more reliable failure. Wrap the entire test that
9610 causes the broken Solaris printf to dump core, in a subshell,
9611 so the segmentation fault message is reliably suppressed.
9612 Fix shell expansion errors by using /usr/ucb/echo always;
9613 avoid an error on systems without it by another subshell.
9614 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9615 subshell-$as_echo to `as_echo', for better error message.
9617 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9619 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9620 `BASH_SOURCE' contain a newline, set them to empty, as they may
9623 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9625 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9626 years and is too hard to maintain now. The last straw was
9627 reported by Jerker Baeck in
9628 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9629 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9630 * doc/autoconf.texi (Particular Functions): Move
9631 AC_FUNC_SETVBUF_REVERSED from here...
9632 (Obsolete Macros): ... to here. Say that it does nothing now.
9633 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9634 Turn into (almost) a no-op.
9636 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9638 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9639 These macros are obsolescent and new applications shouldn't need them.
9640 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9641 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
9642 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
9643 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
9644 (AC_FUNC_VPRINTF): Likewise.
9645 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
9646 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9647 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9649 * doc/autoconf.texi (Setting Output Variables): Mention that
9650 @VAR1@VAR2 has unspecified behavior. Problem reported by
9652 * NEWS: Mention this.
9654 * Makefile.am: Put only a single '#' into the copyright notice,
9655 so that it's also present in the output file. Standardize wording
9656 in makefile copyright notices to match GNU coding standards.
9657 * bin/Makefile.am: Likewise.
9658 * doc/Makefile.am: Likewise.
9659 * lib/Makefile.am: Likewise.
9660 * lib/freeze.mk: Likewise.
9661 * lib/autoconf/Makefile.am: Likewise.
9662 * lib/autoscan/Makefile.am: Likewise.
9663 * lib/autotest/Makefile.am: Likewise.
9664 * lib/m4sugar/Makefile.am: Likewise.
9665 * man/Makefile.am: Likewise.
9666 * tests/Makefile.am: Likewise.
9667 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
9670 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9672 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9673 in the sed script that mangles the awk script: delete up to the
9674 first exclamation mark only.
9675 * tests/torture.at (Substitute and define special characters):
9678 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9680 Rewrite config files generation: avoid quadratic growth in
9681 the number of substituted variables by using awk instead of sed
9682 for the bulk of the substitutions.
9683 * NEWS: Mention this.
9684 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9685 forbidden in the output (and thus input) file.
9686 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9687 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9688 generate just one large awk script for substitutions,
9689 eliminating much of the earlier complexity, while adding some
9690 new complexity. Only expand the substitution templates at
9691 configure time, for smaller configure script size. If
9692 _AC_SUBST_FILES are used, test 'awk' for working getline support
9693 at config.status time. If absent, interpolate through the
9694 shell. The awk script was written with much help
9695 from Paolo Bonzini and Paul Eggert.
9696 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9697 (_AC_SED_FRAG_NUM): Likewise.
9698 (_AC_SUBST_CMDS): Renamed from...
9699 (_AC_SED_CMDS): ...this.
9700 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9701 * tests/torture.at (Substitute a 2000-byte string): Also
9702 substitute a line with 1000 words, and a variable with several
9704 (Substitute and define special characters): Test awk special
9705 characters, and put substitution input strings `@foo@' in the
9706 output, to test that no recursion happens; test several other
9707 combinations from Paolo Bonzini.
9709 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9711 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9712 that replaced echo with AS_ECHO where this wasn't necessary.
9713 Problem reportd by Ralf Wildenhues.
9714 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9715 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9716 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9718 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9720 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9722 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9724 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9725 that traditional Awk lacks 3-arg "split". It has it.
9726 Mention that FS must be a single character, and a few other
9727 99-byte limits of traditional Awk.
9728 Mention that if (i in a) doesn't work with traditional Awk.
9730 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9732 * tests/autotest.at (BSx641-newline in command):
9733 (BS-BS-newline in command, BSx640-newline in command):
9734 (Newline-CODE-BS-newline in command):
9735 (Single-quote-BS-newline in command):
9736 (Single-quote-newline-BS-newline in command):
9737 Use printf '%s\n' instead of echo, for portability to hosts
9738 where echo interprets backslashes. This will break on hosts
9739 that lack printf, but for now let's assume all such hosts
9740 are dead (if not, we should get reports of test failures).
9742 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9744 'echo' has some portability problems, when given a first argument
9745 with a leading '-', or when given any argument containing '\'.
9746 Avoid using 'echo' in these cases.
9747 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
9748 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
9749 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9750 * lib/autotest/general.m4 (AT_INIT): Likewise.
9751 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
9752 argument might be unportable.
9753 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
9754 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
9755 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
9756 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
9757 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
9758 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
9759 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
9760 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
9761 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
9762 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
9763 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
9764 (AC_PROG_MAKE_SET): Likewise.
9765 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
9766 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
9767 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
9768 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

9770 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
9771 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9772 * bin/autoconf.as: Redo verbose flag implementation, as the old
9773 scheme wouldn't work with AS_ECHO.
9774 * lib/autotest/general.m4 (AT_INIT): Likewise.
9775 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9776 Don't use ECHO_T, since ECHO_N is now reliable.
9777 * lib/autotest/general.m4 (AT_INIT): Likewise.
9778 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9779 rather than using a here-document to put the script into a file.
9780 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9782 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9783 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9784 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9785 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9786 * lib/autotest/general.m4 (AT_SETUP): Likewise.
9787 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
9788 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9789 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9790 operand, as AS_ECHO requires. Avoid double file name expansion.
9791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9792 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9793 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9794 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9795 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9796 Double-quote strings that would otherwise contain M4 comments.
9797 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9799 * configure.ac (AC_INIT): Bump to 2.61a.
9802 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9806 * configure.ac (AC_INIT): Bump to 2.61.
9809 * tests/autotest.at (Macro with backslash in a test title):
9810 Comment out for now, as this tests neither fails nor passes
9811 reliably. Problem reported by Ralf Wildenhues.
9813 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9815 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9816 in previous change, which caused test failures.
9818 2006-11-16 Stepan Kasal <kasal@ucw.cz>
9820 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
9821 code for --enable, --disable, --with, and --without to...
9822 (_AC_INIT_PARSE_ENABLE): ... a new macro.
9823 * doc/autoconf.texi (Package Options):
9824 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
9826 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9828 Import these changes from config via gnulib:
9830 2006-11-15 Ben Elliston <bje@gnu.org>
9832 From Josselin Mouette <joss@debian.org>:

9853 Import this change from gnustandards via gnulib:
9855 2006-11-15 Karl Berry <karl@gnu.org>
9857 * standards.texi: core -> memory, throughout.
9858 (CPU Portability): show correct example of calling write
9859 on a char value; thanks to Paul Eggert for the code.
9860 Both of these suggestions from Eugene Y. Vasserman.
9863 Import these changes from texinfo via gnulib:
9865 2006-11-08 Karl Berry <karl@gnu.org>

9868 as well as pdf images, since they are supported in pdftex with
9871 2006-11-05 Karl Berry <karl@gnu.org>
9873 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.
9875 2006-11-13 Paul Eggert <eggert@cs.ucla.edu>
9877 * NEWS: Document the AC_ARG_WITH change.
9879 2006-11-13 Bruno Haible <bruno@clisp.org>
9881 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
9882 options, transliterate also dots to underscores.

9904 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9905 Imported from a similar patch to gnulib by Bruno Haible.
9907 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

9931 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9932 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9933 argument. Extend to check titles printed by ./micro-suite and
9934 ./micro-suite -l and the title in micro-suite.log.
9935 (Backquote in a test title,
9936 Single-quote in a test title,
9937 Double-quote in a test title): Don't expect failure anymore.
9938 (Backslash in a test title): Put a non-whitespace character after the
9939 backslash so that Bourne shells might actually see it as an escape
9941 (Brackets in a test title,

9951 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9952 The visible effect was a stray [] in the testsuite output.
9954 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9959 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9961 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9962 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9963 5363) simply issues a warning when dividing by zero at compile
9964 time. Problem reported by Elias Pipping.
9966 2006-10-26 Eric Blake <ebb9@byu.net>
9969 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9970 show effect on macros that expand with commas.

9998 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9999 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
10000 reported by Nelson H. F. Beebe for Coreutils 6.4.
10002 * tests/tools.at (autoconf --trace: user macros): Remove test
10003 for tracing multiline macros, since m4 1.4.7a uses a different
10004 way to number lines. Problem reported by Ralf Wildenhues.
10006 2006-10-24 Stepan Kasal <kasal@ucw.cz>
10008 * bin/autom4te.in (handle_m4): Do not redirect stdin to
10009 /dev/null since the heuristics for interactive behaviour was

10082 (Imported from Automake.)
10083 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
10084 which incorrectly sets the mode of an existing destination
10085 directory. In some cases the unpatched install-sh could do the
10086 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
10087 system. We hope this is rare in practice, but it's clearly worth
10088 fixing. Problem reported by Alex Unleashed in
10089 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
10090 Also, don't bother to check for -m bugs unless we're using -m;
10091 suggested by Stepan Kasal.

10137 2006-10-13 Stepan Kasal <kasal@ucw.cz>
10139 * doc/autoconf.texi (Autoheader Macros): Warn that the text
10140 added to the template can get mangled.
10142 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10144 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
10145 include the default headers, and redefine obstack_chunk_alloc
10146 and obstack_chunk_free. Fixes false failure with glibc.

10168 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
10169 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
10170 Use a better substitute, by inspecting the output of "ls"
10171 rather than just using ":".
10172 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
10173 rather than AS_EXECUTABLE_P, since we needn't worry about
10174 non-regular files here.
10176 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
10177 due to configuration hassles with this. See Tonya Underwood's report

10201 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
10202 comment about ac_cpp_err; it was incorrect, and anyway
10203 ac_cpp_err is being removed below.
10204 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
10205 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
10206 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
10208 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
10209 with werror_flag and conftest.err and so forth. This is more
10210 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
10211 and anyway the user shouldn't normally want to see this gorp logged.
10212 Problem reported by Ralf Wildenhues.
10213 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
10214 empty, not 'no', since the rest of the code uses 'test -z'.

10218 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10219 Use a single call to AC_DO_TOKENS rather than multiple, for
10221 (_AC_LINK_IFELSE): Test that resulting file is executable.
10222 Problem reported by mwoehlke in
10223 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
10225 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
10226 than creating a file to use with test -x; this is much faster.
10228 2006-10-02 Bruno Haible <bruno@clisp.org>
10230 * lib/autom4te.in (Automake-preselections): Add

10235 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

10240 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
10241 fseeko testing program twice; just use the earlier result.
10242 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
10243 Set cache var to 'unknown' (not 'no') if leaving the macro unset
10244 still doesn't let the program compile.
10245 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
10248 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
10249 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
10250 include it, without including anything else.
10251 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant

10270 values. Problem reported by Ralf Wildenhues.

10481 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
10483 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
10484 didn't work if some values were cached but not others. Test for
10485 broken lex libraries like native ia64-hp-hpux11.22; see
10486 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

10720 reported by Keith Marshall. Also, don't bother with builddir2,
10721 since it shouldn't be needed any more.
10723 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

10744 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10745 Require that long long int be at least 64 bits wide. C99 requires
10746 this and enough programs depend on it so we should check for it.
10747 Bruno Haible reports in
10748 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10749 that long long int is 32 bits wide with some nonstandard compilers.

10760 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10762 * doc/autoconf.texi: Be more consistent about using @acronym with
10763 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10764 quite right (it talked about "OSF/Tru64", even though the
10765 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10766 and it even mentioned "OSF 4"!) and at this point there's little
10767 reason to talk about OSF any more, since it died in 1994.
10768 (Specific Compiler Characteristics): Simplify example of
10769 negative-size array.
10770 (File Descriptors): Reorder to make the text flow better.
10771 Remove joke about "appreciate the various levels"; I didn't get it.

10775 Tone down the advice against renaming or removing open files.
10776 (Limitations of Usual Tools): Add a new section, on 'rm'.
10778 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10780 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10781 -lXt in LIBS, idea from Karsten Hopp; this was due since
10784 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10785 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10786 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10787 (which belong to Xt, not X itself). See Debian bug 327655.
10789 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10791 * configure.ac (AC_INIT): Bump to 2.60a.

10798 * configure.ac, NEWS: Update.
10800 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10802 * config/texinfo.tex: Sync from upstream.
10804 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10805 quadrigraph correctly in traces.
10807 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10810 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10811 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10813 * doc/autoconf.texi (Changed Directory Variables): New node,
10814 to document the whole `datarootdir' business a bit better.
10816 * tests/torture.at (datarootdir workaround): Extend test.
10817 Prompted by report by Alexandre Julliard.
10819 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10821 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10822 when using default mode of IBM C 6 for AIX. Problem and two-line
10823 fix reported by Larry Jones.
10825 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10827 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10828 about literal '${datarootdir}' if a definition is found in the
10831 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10833 * NEWS: Use "M4" rather than "m4" when appropriate.
10834 Problem reported by Eric Blake.
10835 * doc/autoconf.texi: Likewise.
10836 Use @acronym around BSD, GCC, and GNU when appropriate.
10837 (Why GNU M4): Renamed from "Why GNU m4".
10838 (Redefined M4 Macros): Mention that Posix
10839 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10840 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10843 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10845 * bin/autom4te.in (handle_output): Do not forbid the empty
10847 * tests/tools.at (autoconf: the empty token): New test.
10849 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10851 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10852 calls, so that we do not care whether they are LIFO or FIFO;
10853 in the m4_wrap, do not check which diversion is the topmost
10854 one, just check that the stack is balanced at the end.
10855 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10856 base diversion forever--pop the previous diversion before
10857 opening the new one; consequently, remove the m4_wrap call.
10858 * lib/autotest/general.m4 (AT_INIT): Likewise.
10859 * tests/m4sugar.at: Do not use
10860 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10862 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10863 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10865 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10866 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10867 Rework example of m4wrap token-pasting trouble so that it doesn't
10868 care whether it's LIFO or FIFO.
10869 Fix some "contrary to"s that are awkward in English.
10871 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10873 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10874 to `yes' instead of `int$1_t' if the type is found, for more
10875 consistent configure output (where $1 is the number of bits).
10876 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10877 Suggested by Bruno Haible.
10879 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10880 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10881 with system headers. Report by Bruno Haible.
10883 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10885 * config/config.guess, config/config.sub: Sync from upstream.
10887 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10888 in order to avoid picking up an older installed frozen m4sh.m4f.
10889 Besides an outdated shell startup, this could have been created
10890 by an earlier M4 version with incompatible frozen file format.
10892 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10894 * README: Recommend m4 1.4.4 instead of 1.4.3..
10895 * doc/autoconf.texi: Likewise.
10896 (Special Chars in Names): Say that $(.FOO) is portable, as
10897 suggested by Stepan Kasal.
10898 (Installation Directory Variables, Build Directories):
10899 (Automatic Remaking, Subdirectories, Fortran Compiler):
10900 (Making testsuite Scripts, Defining Directories):
10901 Quote variable usages better.
10902 (Making testsuite Scripts): Add clean-local rule to makefile
10903 snippet, by Eric Blake.
10904 (Installation Directory Variables): Fix table item font.
10905 Reword slightly to clarify. Generalize advice about
10906 not using special characters to include all file-related
10907 vars, not just VPATH.
10908 (Special Chars in Variables): Warn about special characters in
10910 (Assignments): Clarify default-value example as suggested by
10912 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10913 (Special Shell Variables): Note leading ./ or ../, as suggested
10915 (Limitations of Builtins): Under cd, warn about CDPATH.
10916 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10919 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10921 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10922 `@var', for texi2html.
10923 (Systemology): Some more word wrapping, for DVI output.
10924 (autom4te Invocation): The short option for `--melt' is `-M',
10927 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10929 * doc/autoconf.texi: More formatting and English tweaks,
10930 many suggested by Ralf Wildenhues.
10931 Reword to avoid "@code{...}'s" and the like, since it's ugly
10932 with Emacs info mode. discontents -> woes.
10933 Put a few "will"s back. time stamp -> timestamp.
10934 side-effect -> side effect.
10936 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10938 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10939 Warn about $@ not persisting. Problem reported by Julien Danjou in
10940 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10941 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10942 Mention other special chars, too.
10944 2006-06-14 Eric Blake <ebb9@byu.net>
10946 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10948 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10950 * doc/autoconf.texi: Some systematic minor improvements, as
10951 follows. Use "makefile" when talking about makefiles
10952 generally (which might be named "makefile" or "Makefile" or even
10953 "foo.mk"), "Makefile" when talking about a specific makefile
10954 called "Makefile". This unclutters the text from weird quotes
10955 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10956 values" rather than "@var{foo}s" and similar constructs containing
10957 "}s". Use "Make rules" rather than "Makefile rules". Minor
10958 English-language improvements. Change the prefix "sub-" to "sub"
10960 Put blank lines around examples more consistently.
10961 Avoid "rather" and "very" as intensifiers.
10962 Avoid "will" as an auxiliary.
10963 (Limitations of Make): Split this node into....
10964 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10965 (Leading _ in Macro Names, Backslash-Newline-Newline):
10966 (Backslash-Newline Comments, Long Lines in Makefiles):
10967 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10968 (obj/ and Make, make -k Status, VPATH and Make):
10969 (VPATH and Double-colon, $< in Explicit Rules):
10970 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10971 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10972 New nodes, resulting from splitup of Limitations of Make.
10973 All cross-references changed. Raise the top node from
10974 a section to a chapter, and all subnodes accordingly.
10975 Redo the introductory wording to match the new organization.
10976 (Installation Directory Variables): Use an example that is
10977 closer to what Autoconf actually does. Mention that VPATH's
10978 value should not contain metacharacters or white space.
10979 (Fortran Compiler): Fix a VPATH bug in an example.
10980 (Leading _ in Macro Names): Mention that this problem is no longer
10981 of practical concern.
10982 (VPATH and Make): Reword the advice to make it clearer
10983 that Autoconf and Automake support VPATH in non-GNU make, but
10984 many packages have bugs in this area.
10985 ($< in Explicit Rules): Refer to Build Directories rather
10986 than using a (non-VPATH-safe) example.
10987 (Automatic Rule Rewriting): Mention the sort of disaster that
10988 can ensue with Solaris-style rule rewriting with VPATH.
10990 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10992 * doc/install.texi (Compilers and Options): Weaken the
10993 suggestion to use GNU make for VPATH builds.
10995 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10996 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10998 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10999 in regular expression.
11001 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11003 * doc/autoconf.texi (Installation Directory Variables):
11004 Drop extra @samp from `@table @samp' item.
11005 (Limitations of Usual Tools): Comment fix.
11006 Do not nest @samp just to point to other table items.
11007 (Writing testsuite.at) <AT_CHECK>: The second argument to
11008 `@dvar' is already @samp'ed.
11009 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
11010 do not use @var in the second argument.
11012 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
11014 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
11015 $as_shell.exe too. Problem reported by Andreas Buening in
11016 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
11018 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11020 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
11021 `unused variable' compiler warning, for `-Wall -Werror'.
11022 Reported by Jaap Haitsma in
11023 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
11025 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
11027 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
11028 case the compiler dumps core. Problem reported for
11029 OpenServer 5.0.7 by Tim Rice in
11030 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
11031 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
11034 2006-06-06 Tim Rice <tim@multitalents.net>.
11036 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
11037 "ERROR" only shows up in "make check" output if there is an

11046 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
11048 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
11049 typically overflows on x86 CPUs, even though the C standard
11050 requires otherwise.
11052 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11054 * configure.ac (AC_INIT): Bump to 2.59e.
11057 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11061 * config/texinfo.tex: Sync from upstream.
11063 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
11064 seen, invoke libtoolize with `--ltdl' argument.
11065 * lib/autom4te.in (Autoreconf-preselections): Adjust.
11067 Suggested by Eric Blake.
11069 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
11071 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
11072 reported by Ralf Wildenhues.

11081 * doc/autoconf.texi: Modernize some of the references to Solaris.
11083 2006-06-05 Stepan Kasal <kasal@ucw.cz>
11085 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
11086 message issued by AC_REQUIRE.
11087 * tests/m4sugar.at: Check m4_require's error message.
11088 * tests/base.at: Check AC_REQUIRE's error message.
11089 * tests/local.at (AT_CHECK_M4): New macro, almost identical
11091 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
11093 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
11094 `expout' as the last parameter.
11095 * tests/tools.at: Adapt to the above change.
11097 2006-06-04 Stepan Kasal <kasal@ucw.cz>
11099 * doc/autoconf.texi (Limitations of Usual Tools): Correct
11100 information about race-free implementations of mkdir.
11102 2006-06-04 Eric Blake <ebb9@byu.net>
11104 * bin/autoreconf.in (help): Document M4 environment variable.
11105 * bin/autoconf.as (Usage): Likewise.

11109 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
11111 * NEWS: GNU make now recommended for VPATH builds.
11112 Mention that some macros are now documented to be obsolescent.
11113 * doc/autoconf.texi:
11114 Prefer "current" to "modern" to describe
11115 currently-used (albeit perhaps old-fashioned) hosts.
11116 Mention which ancient features no longer need to be worried about.
11117 setgid -> set-group-ID
11118 setuid -> set-user-ID (these are the Posix terms)
11119 Fix some misuses of "only".
11120 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
11121 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
11122 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
11123 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

11127 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
11128 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
11129 Mention that these macros are obsolescent.
11130 (Installation Directory Variables): shall -> should
11131 (File Descriptors): Mention that 0, 1, 2 might get reopened.
11132 Mention that it's now safe to use 3 and 4.
11133 (Limitations of Usual Tools): cp -r is now specified by Posix.
11134 Omit longwinded and obsolescent discussion of cp -f.
11135 Modernize discussion of expr, ls.
11136 (Limitations of Make): Modernize discussion of VPATH builds.
11137 Mention $? as a workaround in some cases.
11138 * doc/install.texi (Basic Installation):
11139 Mention "./configure; make; make install" first. Be more
11140 specific about why this file is generic. Remove unnecessary
11141 parens. Remove misleading "only". Remove obsolete advice
11142 about csh. Don't say "configure" takes awhile; say it
11143 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
11144 and CC=c99 rather than CC=c89, as these are blessed by current
11145 Posix. Recommend GNU make if doing a VPATH build.
11147 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
11149 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
11150 examples involving shell prompts.
11152 2006-06-02 Stepan Kasal <kasal@ucw.cz>
11153 and Paul Eggert <eggert@cs.ucla.edu>
11155 * doc/autoconf.texi (Here-Documents): Add details about the
11156 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
11157 use "here-documents" instead of "here documents".
11159 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11161 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

11168 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
11170 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
11171 about quoting the case statement, just in case.
11172 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
11173 was fixed in ksh93g; reported by Ralf Wildenhues.

11186 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
11187 argument with leading hyphen. Problem reported by Paul Eggert.
11189 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11191 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
11192 about quoting ac_try: quote all of it, if any of it seems suspicious.
11193 This means we don't have to worry about ${ or sed any more.
11194 Also, double-quote the case statement, to work around misuses via
11195 underquoting as reported by Ralf Wildenhues in
11196 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
11197 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
11198 undocumented and dangerous macro.
11199 Problem reported by Ralf Wildenhues in
11200 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

11206 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
11208 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11210 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
11211 since evidently some packages rely on the old, broken behavior.
11212 Problem reported by Ralf Wildenhues in
11213 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
11214 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
11215 pre-2006-05-26 definitions, but leave in the comments that
11216 these macros are dangerous and should not be used.
11217 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
11218 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
11219 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
11220 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
11221 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
11223 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
11225 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
11226 the use of 'tr', since this is our only use of 'tr'.
11228 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11229 and Paul Eggert <eggert@cs.ucla.edu>
11231 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
11232 Don't assume 'grep' works on long lines, since AIX grep doesn't.
11234 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11236 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
11237 the output file in the `${datarootdir}' test.
11239 2005-05-28 Stepan Kasal <kasal@ucw.cz>
11240 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11242 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
11243 mention of `datarootdir' in the input file(s), but literal
11244 `${datarootdir}' in the output file, and we haven't warned yet,
11245 then warn as well: the user may have (erroneously) used
11246 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
11247 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
11248 * tests/torture.at (datarootdir workaround): Extend this test.
11251 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11252 and Paul Eggert <eggert@cs.ucla.edu>
11254 * doc/autoconf.texi (autoheader Invocation): The first argument to
11255 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
11256 alternatives and clear up the language a bit.
11258 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
11260 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
11261 ac_config_guess, ac_config_sub, ac_configure.
11262 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11263 Fix typo that prevented an unnecessary space from being removed.
11264 Problems reported by Ralf Wildenhues in:
11265 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
11267 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
11269 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
11270 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
11271 Don't use the term "thread-safe" to talk about mkdir race
11272 conditions, since the problem is more a process than a thread
11273 issue. Problem reported by Stepan Kasal in:
11274 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
11275 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
11276 the test for 'install' more closely. Look at MKDIR_P first.
11277 Look in the PATH, and at /opt/sfw/bin.
11278 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
11279 Don't bother to try mkdir -p, since we already check mkdir --version;
11280 just look at the version number. (There's no easy way to check
11281 for race-free implementations.)
11282 * tests/tools.at (autoconf: subdirectories): Adjust to above
11283 changes, since MKDIR_P now might end in "/mkdir -p".
11285 * doc/autoconf.texi (autoheader Invocation): Mention that the
11286 first arg of AC_DEFINE_UNQUOTED must be a literal.
11287 Problem reported by Ben Pfaff in
11288 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
11290 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
11291 * doc/autoconf.texi (Special Chars in Variables): New section.
11292 (Preset Output Variables): Warn about special chars in CPPFLAGS.
11293 (Installation Directory Variables): Quote $(datadir) better.
11294 (Limitations of Builtins): Describe some of eval's trickiness.
11296 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
11297 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
11298 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
11299 in front of every arg, not just trailing args. Quote apostrophes.
11300 (_AC_EVAL_ECHO): New macro.
11301 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
11302 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
11304 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
11305 exposed by quoting of eval argument. Put the command on line line
11307 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
11308 (_AC_PATH_X, AC_PATH_X): Quote more safely.
11309 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
11310 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
11311 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
11312 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
11313 Use eval more safely.
11314 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
11315 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
11317 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
11318 lines, exposed by quoting of eval argument.
11320 2006-05-26 Stepan Kasal <kasal@ucw.cz>
11321 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11323 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
11324 initialization of `ac_cv_exeext', do not override it if it was
11325 already set, unless it was set to `no', for compatibility with
11326 Autoconf-2.13, and comment this.
11327 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
11328 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
11329 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
11330 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
11331 Document that this test may be overridden by setting
11334 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11336 Revert these two patches:
11338 2006-04-06 Eric Blake <ebb9@byu.net>
11339 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11340 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11343 2006-04-01 Stepan Kasal <kasal@ucw.cz>
11344 Clean up _AC_COMPILER_EXEEXT* macros.
11345 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11346 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
11347 ac_file to the name of the default output file and call
11348 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11349 initial `rm' of the candidate files...
11350 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11351 the same list in subsequent `rm' calls, and for the temporary
11352 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11353 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11354 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11355 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11356 no longer needed) by libtool. Make it a cache check.
11357 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11358 copied here by mistake.
11359 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
11360 _AC_COMPILER_EXEEXT.
11361 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
11362 _AC_COMPILER_OBJEXT directly.
11363 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11365 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11367 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
11368 Fix description of how the buggy `sed' works.
11370 2006-05-25 Noah Misch <noah@cs.caltech.edu>
11372 Sync from Automake:
11374 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
11375 ENOLCK. Only mention `make -j' when applicable. Only raise
11376 fatal errors when `make -j' is involved. Improve error message.
11378 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11380 * doc/autoconf.texi (Here-Documents): We now know more about
11381 the variable expansion in here documents bug.
11382 Thanks to Tim Rice and Stepan Kasal.
11384 * doc/autoconf.texi (Making testsuite Scripts): Add an example
11385 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
11387 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11389 * tests/autotest.at (Multiline command from M4 expansion):
11390 No failure to be expected if the shell quotes newlines in
11391 commands in the `set -x' output. Report by Tim Rice.
11394 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11396 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
11397 expansion in the here-documents used by config.status, as that
11398 runs afoul of the Korn shell version M-12/28/93d bug described in
11399 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
11400 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
11401 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
11403 2006-05-23 Jim Meyering <jim@meyering.net>
11405 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
11406 Fix typo introduced with 2006-04-02 change. It reversed the sense
11409 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11411 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
11412 ac_dB slightly, to save bytes in the script.
11413 Max out at 50 lines, rather than 96; this is more likely
11414 (though not guaranteed) to avoid obscure 'sed' failures.
11416 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11418 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11419 `tr -d -' as bad option argument. Work around this by deleting
11420 an unrelated character.
11421 Report by Tim Rice <tim@multitalents.net>.
11423 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11424 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11425 Stepan Kasal <kasal@ucw.cz>
11427 * doc/autoconf.texi (Particular Programs): Do not promise that
11428 we always prefer the GNU version of the program, and that we
11429 search according to PATH; both rules can have exceptions.
11430 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11431 AC_PROG_SED. Move descriptions of limitations
11432 to the Limitations of Usual Tools section.
11433 (Limitations of Usual Tools) <sed>: Mention script length
11434 limitations with Solaris /usr/ucb/sed.
11435 <grep>: Fix wording for empty alternative. Mention that -c and
11436 -l should not be combined, and that -E and -F should not be
11439 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11440 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11442 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11443 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11445 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11447 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11448 AC_DEFINE is now passed to m4_pattern_allow.
11449 * NEWS: Mention that; likewise for AC_SUBST.
11450 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11451 the parameter to m4_pattern_allow.
11452 * tests/tools.at: Add a check for that.
11454 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11456 * lib/autoconf/status.m4: Fix typos.
11458 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11460 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11461 only the files that this macro generates.
11463 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11465 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11466 the HP-UX sed limitation of 99 commands, labels do not count.
11467 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11469 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11471 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11473 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11474 Import the following fix from coreutils:
11476 2006-01-13 Jim Meyering <jim@meyering.net>
11478 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11479 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11480 not double-quote uses of that variable, to accommodate the rare
11481 case in which getmntent is available in none of the libraries
11482 checked. This happens at least on FreeBSD 5.0.
11484 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11486 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11487 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11488 some other programs unwisely rely on these undocumented vars.
11489 But put in warning comments about them.
11490 Problem reported by Ralf Wildenhues in
11491 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11492 * NEWS: Document that these variables are intended to go away.
11494 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11496 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11497 and set the language to C++ (analogous to the equivalent Fortran
11500 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11501 * doc/autoconf.texi (C++ Compiler): Document it.
11502 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11505 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11507 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11508 that caused config.status to generate 100-command sed scripts; the
11509 portable limit is 99.
11511 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11513 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11514 variable `ac_d' instead of `d' to avoid infringing namespace.
11515 Report by Ralf Menzel.
11517 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11519 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11520 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11521 * tests/tools.at (autoconf: subdirectories): New test, taken from
11522 the corresponding problem report by Ralf Wildenhues in:
11523 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11525 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11526 Quote some uses of shell variables if they might suffer unexpected
11527 globbing. This doesn't fix all instances of quoting problems that
11528 I found, just the easy ones that look safe.
11529 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11530 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11531 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11532 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11533 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11534 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
11535 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
11537 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
11538 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
11540 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11542 * bin/autoreconf.in ($help): Reword according to the manual.
11543 Suggested by Olly Betts.
11545 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11546 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11548 * bin/autoreconf.in: Pass the directory argument to
11549 `require_configure_ac'. Fix comment.
11550 * tests/torture.at (Configuring subdirectories): Expose this.
11551 Reported by Olly Betts.
11553 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11555 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11556 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11557 Automake as follows:
11559 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11560 `$configure_in' instead of `configure.in', to preserve
11561 directory component.
11563 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11565 * config/config.guess, config/config.sub, config/texinfo.tex,
11566 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11568 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11570 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11571 test for C99 conformance; (bool) 0.5 is an integer constant
11572 expression, but (bool) -0.5 is not. Problem reported by Fedor
11573 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11575 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11577 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11578 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11579 Warn about obsolete install-sh files. Remove stray sentence
11580 fragment and fix cross reference.
11581 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11582 install -d; this undoes the 2006-05-10 change.
11583 (MKDIR_P): Mark with AN_MAKEVAR.
11584 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11585 that we don't require $INSTALL to be thread-safe. Move comments
11586 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11587 of AC_PROG_INSTALL. Output a message saying that we're checking
11588 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11589 MKDIR_P instead of AC_SUBST.
11590 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11591 Special magic for MKDIR_P, too.
11592 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11594 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11596 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11598 Sync from Automake, as follows:
11600 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11601 * config/install-sh: Initialize IFS, so field splitting isn't
11603 * config/mkinstalldirs: Likewise.
11604 * config/missing: Remove superfluous quotes. Replace all uses of
11605 `[' by `test', for consistency, and for..
11606 * config/missing (sed_minuso, sed_output): New variables.
11607 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11608 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11609 Fixes `missing' to detect `--output' for help2man. Fixes
11610 PR automake/483. Report by Dennis J. Linse.
11611 (autom4te): Document in `missing --help'.
11613 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11615 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11616 * config/install-sh: Don't use 'path' to talk about file names,
11617 as per GNU coding standards. Close a race condition reported by Ralf
11618 Wildenhues and Stepan Kasal. There is still a race condition
11619 on hosts that predate Posix 1003.1-1992, but we can't help this.
11620 Don't mishandle weird characters like space on pre-Posix hosts.
11621 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11622 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11623 AC_PROG_MKDIR_P from AS_MKDIR_P.
11624 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11625 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11626 earlier editions are not (including Automake 1.8.3).
11627 Do not suggest mkinstalldirs for thread-safety.
11628 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11629 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11630 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11631 presence of special characters and race conditions.
11632 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11633 in Autoconf's name space.

11639 from Automake with minor changes.
11640 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11642 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11644 * config/install-sh: Update to Automake CVS version, as follows:
11645 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11646 * lib/install-sh: Simplify the expr implementation of dirname.
11647 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11648 * lib/install-sh: Handle --, and diagnose unknown options.
11650 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11652 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11653 `./autom4te' to create `./testsuite', since the `all' target
11654 will ensure its presence, but `installcheck' should not create
11655 the uninstalled wrappers.
11657 * tests/torture.at (Unusual Automake input files): Skip if we
11658 detect automake < 1.8.
11660 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11662 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11663 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11664 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11667 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11669 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11670 munge (multiple) white space and other oddities.
11671 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11672 single quotes in variable assignment.
11673 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11674 and similar failures by adding multiple spaces, tabs, and other
11675 special characters.
11676 Report and different test suggested by Francesco Romani
11677 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11679 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11680 single quotes, we only need to search for single quotes; this
11681 both simplifies the search pattern, and makes us less
11682 susceptible to `echo' variations for arguments not containing
11684 (_AC_ARG_VAR_VALIDATE): Likewise.
11686 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11688 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11689 `$*' and IFS concatenation issue with traditional shells and
11690 bash-2.04. Report by Seanster@Seanster.com.
11692 2006-05-03 Bruno Haible <bruno@clisp.org>
11694 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11695 precisely which Mac OS X versions have the od problem.
11697 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11699 * doc/autoconf.texi: Use @option systematically.
11701 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11702 and Bruno Haible <bruno@clisp.org>
11704 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11706 (Integer Overflow): Mention the special case of integer division
11709 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11711 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11712 traditional shells like the Solaris one that do not use the
11713 first IFS character for assembling `$*'.
11714 Prompted by a related report from autoconf_bug@nro.ca.
11716 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11717 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11719 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11720 Mention more problems with the -e option.
11722 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11725 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11727 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11728 in URLs to improve DVI formatted output (requires texinfo 4.6).

11736 `action-if-found' -> `action-if-true' and similarly.
11737 (Obsolete Macros): Likewise.
11738 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11739 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11740 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11742 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11744 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11747 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

11759 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11760 (Integer Overflow, Null Pointers, Buffer Overruns):
11761 (Floating Point Portability, Exiting Portably): New sections.
11762 (Writing Test Programs): Fix some langauge. Recommend exiting
11763 with status 1, not merely nonzero. Clarify exit declaration.
11764 (Run Time): Move C exit status stuff to new Exiting Portably section.
11765 (Systemology): Mention Posix and levenez. Update v7 reference.
11766 (Portable Shell): Mention the Posix shell.
11768 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11770 * bin/autoconf.as (me): Replace by as_me.
11772 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11774 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11775 since as_me isn't set yet.
11777 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11779 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11780 a few minor bugs in this area.
11782 * doc/autoconf.texi (Programming in M4sh): Comment out the
11783 documentation of AS_BASENAME, for now.
11784 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11785 (Limitations of Builtins) <basename>: Do not refer to
11787 * bin/autoconf.as (me): Don't use AS_BASENAME.
11788 (dir): Remove the unused variable.
11789 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11790 AS_DETECT_REQUIRED. All uses changed.
11791 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11793 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11794 (AS_BASENAME): Use "basename --" to protect against leading "-".
11795 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11796 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11797 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11798 (_AS_DIRNAME_PREPARE): Likewise.
11799 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11800 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11801 (AS_DIRNAME): Use "dirname --".
11803 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11805 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11806 of "run time" and "run-time" changed to "runtime", for consistency.
11807 * lib/autoconf/fortran.m4: Likewise (in comment).
11808 * lib/autoconf/functions.m4: Likewise.
11809 * lib/autoconf/general.m4: Likewise.
11810 * lib/autoconf/headers.m4: Likewise.
11812 * doc/autoconf.texi (Run Time): Document the exit status situation
11813 with more accuracy and detail.
11815 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11817 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11818 Archive is not officially `GNU' any more. Update URL.
11819 (Defining Directories): Likewise
11820 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11822 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11824 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11825 newline from the `trap' code to finish `config.log'; the NetBSD
11826 /bin/sh resets the exit status after an empty command, as
11827 documented in doc/autoconf.texi.
11828 Reported by Dalibor Topic <robilad@kaffe.org>.
11830 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11832 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11833 Suggested by Bruno Haible.
11835 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11837 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11838 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11839 Instead, just list the shells that we know work.
11840 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11841 changed. Be more cautious about the _cv_ variable.
11842 * tests/tools.at (Syntax of the shell scripts): Check the
11843 _cv_ variable once, at first, to avoid an internal autoconf error
11844 when sh -n does not work.
11846 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11848 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11850 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11852 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11853 use ">&-" since we're only 99.999% sure that this is portable,
11854 and since the MinGW bug is fixed in a different way.
11855 * lib/autotest/general.m4 (AT_INIT): Likewise.
11857 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11859 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11860 before opening config.log, to avoid hitting a bug on MinGW.
11862 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11864 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11865 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11866 This works around a MinGW bug reported by Eric Paire.
11867 Make sure that all writes to the log file append to it,
11868 rather than possibly losing data.
11869 * lib/autotest/general.m4 (AT_INIT): Likewise.
11871 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11873 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11876 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11880 * configure.ac (AC_INIT): Bump to 2.59d.
11882 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11886 * Makefile.maint (news-date-check): Do not require a leading `*'
11887 before the release date in NEWS.
11889 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11890 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11892 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11893 the instantiated file do not contain the string 'datarootdir'
11894 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11895 @mandir@, replace the reference '${datarootdir}' by the value.
11896 * tests/torture.at (datarootdir workaround): New test.
11897 * NEWS: Advertise this temporary fixup.
11898 Based on a patch by Bruno Haible, reported and analyzed by
11899 Paul Eggert and Noah Misch.
11901 2006-04-12 Eric Blake <ebb9@byu.net>
11903 * tests/autotest.at (Debugging a failed test): Fix comment.
11905 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11907 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11908 all the changes since 2006-04-07.
11910 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11912 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11913 succeeded, but `ln -s file dir' failed, take care to remove the
11914 leftover target before the next test, to prevent its spurious
11915 failure; also make sure `ln file dir' works before selecting it.
11916 Thanks to Keith Marshall for pointing this out.
11919 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11920 assignments in `at_debug_args', so that we put them correctly
11921 in the `run' script.
11922 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11923 Reported by Eric Blake.
11925 2006-04-11 Eric Blake <ebb9@byu.net>
11927 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11928 top-level tests after micro-suite has been run. Used in...
11929 (Debugging a successful test, Debugging script and environment),
11930 (Debugging a failed test): ...these new tests. The first of these
11932 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11933 macro, split out from...
11934 (AT_INIT): ...here, so that using -d also generates a run script.
11935 Document that -d inhibits top-level logging.
11936 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11937 inhibits top-level logging; debug scripts are created.
11939 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11941 * tests/autotest.at (Empty test, Empty check): New test to check it.
11943 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11946 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11948 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11949 the files if a problem appears. Make the empty *.at files
11950 read-only, too. Proposed by Ralf Wildenhues.
11952 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11954 * config/Makefile.am: Add comment to force updated Makefile.in.
11956 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11957 space only patch to this file, this patch causes the Makefile.in
11958 files that include freeze.mk to be updated, and thus have a
11959 newer time stamp again, which in turn makes a pristine CVS
11960 checkout have correct time stamps.
11962 * Makefile.maint (cvs-sv): New macro, to be used..
11963 (config.guess-url_prefix, config.sub-url_prefix)
11964 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11965 point to CVS text checkout of Gnulib files.
11966 (copyright-check): Bump current year.
11967 (announcement): Do not hard-wire `./announce-gen'.
11968 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11970 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11972 (wget_files): Update config.guess, config.sub, texinfo.tex by
11973 `wget-update', now that their URLs work again.
11975 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11977 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11978 Problem noted by Paul D. Smith.
11980 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11982 * doc/autoconf.texi: Remove unused words from word list.
11983 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11984 .x-sc_trailing_space: New files.
11986 * doc/standards.texi: Sync from gnulib.
11988 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11989 `LIBOBJDIR' as experimental.
11991 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11992 with a target directory; it's internally implemented as `cp'
11993 anyway, but since Autoconf advertises the possibility to use
11994 a target directory when LN_S is `ln -s', we need to find out.
11995 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11996 analyzed by Keith Marshall <keith.marshall@total.com>.
12000 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
12002 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
12003 confdefs.h as-is. In general, if it has backslash-newline or the
12004 like, then it doesn't work either to sort or to remove empty
12007 2006-04-09 Stepan Kasal <kasal@ucw.cz>
12009 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
12011 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
12013 * lib/autom4te.in (Automake-preselections): Preselect
12016 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
12018 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
12019 apostrophe within a single-quoted string, as this is the usual
12020 tradition and is easier to read than '"'"'. Don't rely on the
12021 shell treating "$/" like '$/'. Use a more-consistent indenting
12022 style for the trap.
12024 2006-04-09 Eric Blake <ebb9@byu.net>
12026 * tests/autotest.at (Backquote command substitution),
12027 (Multiline backquote command substitution): Remove mistaken
12028 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
12030 (Parenthetical command substitution, Multiline parenthetical
12031 command substitution): here.
12033 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
12035 Import macros from gnulib (often changing their name).
12037 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
12038 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
12039 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

12046 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
12047 The manual mentions Gnulib more prominently.
12048 * doc/autoconf.texi (Gnulib): New node.
12049 (Pointers): Add Gnulib URL.
12050 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
12051 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
12053 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
12054 suggest a #define rather than a typedef for _Bool, and mention
12055 Gnulib rather than trying to substitute stdbool code.
12056 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
12057 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
12058 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
12059 AC_STRUCT_DIRENT_D_TYPE.
12060 (Particular Types): Mention stdint.h and inttypes.h as standard
12062 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
12063 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
12064 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
12065 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
12066 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
12067 (C Compiler): Move AC_C_LONG_DOUBLE to ...
12068 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
12069 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
12070 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
12071 (Coding Style). Don't mention m4_expand_once.
12072 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
12073 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
12074 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
12075 (AC_CHECK_FUNCS): Use it.
12076 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
12077 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".

12079 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
12080 (AC_HEADER_ASSERT): New macro.
12081 (AC_HEADER_STDBOOL): Don't assume "#error" works.
12082 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
12083 Catch a bug in an HP-UX C compiler.

12111 _AS_DETECT_BETTER_SHELL:
12113 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
12114 skip nonexistent directories.
12115 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
12116 only shell candidates which exist.
12117 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
12118 * lib/autotest/general.m4 (AT_INIT): No need to give three

12124 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
12125 distinguish m4sugar macros.

12127 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
12128 test case by Noah Misch <noah@cs.caltech.edu>.
12130 2006-04-07 Stepan Kasal <kasal@ucw.cz>

12141 * doc/autoconf.texi (Programming in M4sh): Document that
12142 AS_MKDIR_P exits the script on failure.
12143 * lib/autotest/general.m4: Remove redundant AS_ERROR.
12145 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12147 * config/elisp-comp, config/install-sh, config/mdate-sh,

12166 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
12167 whether `set' quotes correctly: redirect stderr of the tested
12168 `set', and use a subshell, for Ultrix; use `sed' instead of
12169 `grep' for zsh `set' which may write binary output; match only
12170 at the beginning of a line, to avoid false positives.
12171 In order to avoid false positives by unrelated variables with
12172 multiline content, put the dump algorithm in a subshell and
12173 unset all variables containing newlines (except some which are
12174 special to the shell). Warn about cache variables that are

12182 * tests/mktests.sh: Reword comments.
12184 * tests/mktests.sh: Only skip internal macros starting with
12185 `_AC_' or `__AC_'. Noted by Stepan Kasal.
12186 Update exclusion lists for the test suite to this end:
12187 (AC_ARG_VAR): Do test this now.
12188 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
12189 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).

12220 ac_config_<foo>s again, sometimes normalized, sometimes not.
12221 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
12222 (AC_CONFIG_COMMANDS): Do not do so here.
12223 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
12224 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
12225 2005-07-25 rewrite. Noticed by Noah Misch.
12227 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

12231 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
12232 inside m4_expand_once; it is redundant.

12235 for --help from Cygnus `configure.'
12237 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

12277 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
12278 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
12279 normalizing it, consistent it with previous releases.
12280 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
12282 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

12290 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
12291 Use 'comm' rather than N instances of grep; this also fixes a bug
12292 whereby substrings were incorrectly matched, causing us to not
12293 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
12294 (exclude_list): Exclude empty macros.

12384 the same list in subsequent `rm' calls, and for the temporary
12385 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
12386 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
12387 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
12388 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
12389 no longer needed) by libtool. Make it a cache check.
12390 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
12391 copied here by mistake.

12466 2006-04-01 Stepan Kasal <kasal@ucw.cz>
12468 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
12469 switch all of them on and of when necessary. Fixes the bug when

12520 * bin/autoscan.in: The value of find_configure_ac should be
12521 checked for existence, so we don't barf over a nonexisting

13020 (Coding Style): y is like s with respect to / and ,.
13021 (Limitations of Usual Tools): Document the weird restrictions
13022 that Posix has about { }. Use better quoting.

13086 CONFIG_SHELL in the environment of the configure rerun.
13087 * doc/autoconf.texi (Here-Documents, config.status Invocation):
13088 Suggest passing CONFIG_SHELL absolute, and in the environment

13109 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
13110 Factor functionality to..
13111 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
13112 `AC_SUBST($1)' in the public version.
13113 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
13114 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

13139 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
13140 conftest.o, to see whether the compiler really obeys; rm the object
13141 file before and after the test and register it with ac_clean_files.

13164 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
13165 AC_LANG_PROGRAM, fixing a typo. Don't give details about
13166 the inner workings of AC_LANG_FUNC_LINK_TRY.
13167 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
13168 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
13169 by the function rather than ignoring it.
13170 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
13171 comparing its address. Intel's interprocedural optimization was
13172 outsmarting the old heuristic. Problem reported by
13175 2005-10-19 Stepan Kasal <kasal@ucw.cz>
13177 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

13184 2005-10-04 Stepan Kasal <kasal@ucw.cz>
13186 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
13187 before removing it (chmod -R u+rwx); there are three instances of this.
13189 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13190 Stepan Kasal <kasal@ucw.cz>
13192 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
13193 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
13194 make its content writable before removing it. Remove an errorneous
13195 comment from the end, where the logs of the failed tests are copied
13196 to the main log file.
13198 2005-09-27 Stepan Kasal <kasal@ucw.cz>
13200 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
13201 in case the computer is too quick. Double quote the configure.ac
13204 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
13205 problems if the testsuite were running too fast.
13207 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
13209 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
13210 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
13211 (which belong to Xt, not X itself). See Debian bug 327655.
13212 * NEWS: Mention this.
13214 2005-09-07 Stepan Kasal <kasal@ucw.cz>
13216 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
13218 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
13220 * config/move-if-change: Don't output "$2 is unchanged";
13221 suggested by Ben Elliston. Handle weird characters correctly.
13223 2005-09-06 Stepan Kasal <kasal@ucw.cz>
13225 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
13226 calls, so that the final expansion of this macro is shorter.
13227 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
13228 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
13229 the cleanup there. Use AS_VAR_* macros, to be more general.
13230 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
13232 * lib/autoconf/general.m4: Use AS_IF where appropriate.
13234 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
13236 2005-09-01 Stepan Kasal <kasal@ucw.cz>
13238 * doc/autoconf.texi (Configuration Headers): Add an index entry
13241 2005-08-26 Pavel Roskin <proski@gnu.org>
13243 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
13244 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
13247 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
13249 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13250 The previous patch didn't work, so try a better one.
13252 2005-08-26 Stepan Kasal <kasal@ucw.cz>
13254 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
13255 in the example. Reported by Bruno Haible.
13256 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
13257 "if $undefined_var;" succeeds with my shell.
13259 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
13260 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
13261 but change the m4_divert_text to m4_divert_once.
13263 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
13265 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13266 Work around bug in Solaris /usr/xpg4/bin/awk.
13267 The bug is present in at least Solaris 8 through 10.
13269 2005-08-24 Stepan Kasal <kasal@ucw.cz>
13271 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
13272 some evil values and relying on the fact that $* concatenates the
13273 parameters by the first character from IFS.
13275 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
13276 Stepan Kasal <kasal@ucw.cz>
13278 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
13279 first header appears, define AH_HEADER.
13280 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
13281 Update limitations about when to call AC_CONFIG_HEADERS.
13282 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
13283 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
13284 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
13285 ``Configuration Actions''; fix their index entries.
13287 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
13288 options correctly. Process N-M as M-N if M is smaller than N.
13289 Process ranges correctly so that N-N will run only N.
13290 Sort and uniquify the tests that will be run. If there is more
13291 than one test, reinsert the banners for the tests.
13292 * tests/autotest.at (Keywords): Unmark XFAIL.
13294 2005-08-23 Stepan Kasal <kasal@ucw.cz>
13296 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
13297 before passing the macro name to AH_TEMPLATE.
13299 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
13300 now opens log after option processing; in particular, --version
13301 and --help do not touch config.log.
13303 * Makefile.maint: Revert the change from 2005-08-12.
13305 2005-08-22 Stepan Kasal <kasal@ucw.cz>
13307 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
13309 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
13311 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13313 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
13314 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
13317 * doc/autoconf.texi (Defining Symbols, Changed Results):
13318 Prepend to LIBS, not append, in examples.
13320 2005-08-16 Stepan Kasal <kasal@ucw.cz>
13322 When building in place, set srcdir="."; suggested by Tim Van Holder.
13324 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
13325 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
13326 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
13327 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
13328 does not mean "no --srcdir option".
13330 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13332 * tests/autoscan.at (autoscan): New file.
13333 * tests/suite.at: Use it.
13334 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
13335 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
13337 * tests/autotest.at (Keywords): Test keywords combinations.
13339 2005-08-12 Stepan Kasal <kasal@ucw.cz>
13341 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
13342 add "2>&1"; gzip 1.2.4 prints help on stderr.
13344 2005-07-27 Stepan Kasal <kasal@ucw.cz>
13346 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
13347 was pushdef'ed twice while popped only once. Push it only once.
13348 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
13350 2005-07-26 Stepan Kasal <kasal@ucw.cz>
13352 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
13353 prefixed by mere "===", not "configure: === ".
13355 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
13357 * Makefile.maint: Update from Bison.
13359 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
13360 "<tab>" in comment, so that the point is understandable.
13362 2005-07-25 Stepan Kasal <kasal@ucw.cz>
13364 Rewrite substantial part of lib/autoconf/status.m4.
13365 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
13366 and CONFIG_COMMANDS are not processed in four separate loops.
13367 Instead, there is one main loop. This alows that the common code
13368 is expanded only once, thus config.status (and configure) is smaller.
13370 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
13371 the AC_LIST_FILES and cousins macros are no longer used.
13373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
13374 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
13375 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
13376 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
13377 contain the initialization, nor the for loop, nor the associated
13378 commands; all these go to ...
13379 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
13380 _AC_OUTPUT_CONFIG_STATUS.
13381 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
13382 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
13383 (_AC_OUTPUT_FILE): The creation of the sed script ...
13384 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
13385 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
13386 _AC_OUTPUT_MAIN_LOOP.
13387 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
13388 _AC_CONFIG_COMMANDS): Use ...
13389 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
13390 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
13391 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
13392 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
13393 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
13394 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
13396 (_AC_CONFIG_UNIQUE): Update.
13397 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
13398 Replaced by this ...
13399 (_AC_LIST_TAGS): ... new common macro.
13400 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
13401 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
13402 (_AC_LIST_TAG_COMMANDS): ... new common macro.
13403 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
13404 this didn't belong to the `config commands' section.
13405 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
13406 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
13407 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
13408 to the `config commands' section either.
13409 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
13410 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
13412 ... and many changes to the comments nearby.
13414 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
13415 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
13416 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
13417 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
13418 (#define header templates): The comment at the top of the generated
13419 header now includes the name(s) of the source file(s).
13421 Several unrelated small changes:
13423 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13424 parameter to AC_DIAGNOSE.
13425 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13426 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13427 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13428 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13429 with AU::AC_OUTPUT.
13430 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

13458 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13459 (AC_ARG_VAR): ... here.
13460 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13463 Keep a list of all precious variables and process them with one simple
13464 for loop, instead of expanding all commands, or, OTOH, complicated
13465 processing of output of "set".

13473 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13474 its value to shell variable ac_precious_vars and call
13475 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

13522 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13523 sed substitution command, so that we allow | in program prefixes

13533 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13534 for loop over config.site files using `set', to allow
13535 directory names containing IFS characters.
13537 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13539 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13540 directories with weird names. Apparently some people like living

13562 document to output the default config_* lists to config.status.
13563 Don't recognize option --file, if the functionality is not there.
13564 Likewise for --header; moreover, recognize --he and --h as shortcuts
13565 for --help in that case.
13567 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13568 matches the order of execution. No code changed.

13591 (AC_SUBST): Call it.
13592 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13593 the directory specific variables; but don't call it for configure_input.
13595 2005-06-28 Derek Price <derek@ximbiot.com>
13597 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13600 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13602 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13603 directory have inherent problems with special characters like spaces,
13604 due to limitations in Make syntax. Problem reported by Alexandre
13606 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

13621 variable into diagnostic. Make the diagnostic an error, not a warning,
13622 because we really don't support spaces and suchlike in dir names.
13623 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13624 Don't worry about backslashes in srcdir; it can't happen now.

13637 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13638 that '\|' is not allowed in BREs; recommend using newline separated

13653 (Special Shell Variables): Fix sed code this in the example.
13654 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13655 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13657 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13658 expand to the empty list. Don't use two pairs of m4_changequote,
13659 it's not necessary.

13667 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13668 * doc/autoconf.texi:
13669 Don't mention Solaris versions so much, if a
13670 problem is common to all extant versions of Solaris. Say "SunOS
13671 4" instead of "SunOS" for SunOS 4.
13672 (awk): Mention more of the limitations of traditional Awk.
13673 (cat): Don't talk about cat -v.

13686 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13687 Use shell builtins rather than 'expr', to work around expr bug.
13689 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13691 * doc/autoconf.texi: "filesystem" -> "file system".

13701 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13702 to update the man page. That way, we don't have to check in new
13703 man pages every month.
13705 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13706 quotes and backslashes. Patch from Derek Price.

13719 2005-06-08 Derek Price <derek@ximbiot.com>
13721 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13722 renaming them since they are about to be redefined anyhow.
13724 2005-06-08 Derek Price <derek@ximbiot.com>
13726 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13727 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13728 Move m4_undefine to alphabetical order.
13730 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13732 * README: Recommend GNU M4 1.4.3 or later.
13733 * doc/autoconf.texi (Introduction): Likewise.
13734 Reword to avoid some formatting glitches.
13735 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13736 Clarify explanation of HP compiler bug.
13737 Redo example output tp match current CVS snapshot.
13738 Use @example.org in email addresses when the examples
13739 might get inadvertently cut-and-pasted into user code.
13740 Remove example of autom4te usage that doesn't seem to work now.
13741 Use modern AC_INIT (except when the example is meant to be
13742 shown with Autoconf 2.13).

13756 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13757 Tru64 ksh pattern matching bug. Reported against Libtool by
13758 Albert Chin <libtool@mlists.thewrittenword.com> and
13759 Nicolas Joly <njoly@pasteur.fr>.
13761 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13763 m4_cdr of one-member list was [[]] (one-member list containing an
13764 empty string) instead of [] (an empty list. Callers were skewed to
13765 match this misbehaviour. As a consequence of this:
13766 - m4_foreach([x], [], [foo]) expanded to `foo', while
13767 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13768 This bug has been fixed:
13770 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13771 expand to an empty string; print error msg if called without
13773 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13774 misbehaviour; handle [] and [[]] correctly.
13776 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13778 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13779 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13780 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13782 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13784 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13785 swallow records with more than 99 fields.
13786 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13787 parse the long line.
13789 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13791 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13792 swallow literals longer than 399. Reported by Ralf Wildenhues.
13793 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13794 to workaround this limitation.

13810 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13811 expression of unbounded size when processing the --list
13812 option. This runs afoul of a limit of 399 bytes per regular
13813 expression on AIX. Problem reported by Ralf Wildenhues.

13824 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13826 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13827 now contain newlines, and substituted files must be referenced on

13831 commands can be put in a sed script portably.
13832 * doc/autoconf.texi (Setting Output Variables): Document above

13844 * tests/local.at: Don't attempt to check for negated character
13845 classes in shell scripts. The test was too brittle.
13847 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13849 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

13883 (ac_top_build_prefix): ... to this; the old name is also kept, for
13884 backward compatibility.
13885 (ac_top_builddir_sub): New variable, without the trailing slash,
13887 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13888 * doc/autoconf.texi (Configuration Actions): Rename
13889 ac_top_builddir to ac_top_build_prefix.
13890 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13891 at_top_builddir to at_top_build_prefix.
13892 * lib/autotest/general.m4 (AT_INIT): Likewise.
13894 2005-05-20 Stepan Kasal <kasal@ucw.cz>

13899 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13901 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13902 argument to m4_foreach. I guess it was necessary in the past,
13903 but I think it's a no-op now.
13905 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13907 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13908 ``cat <<_ACEOF'' commands to one.
13909 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13910 * lib/autoconf/status.m4: On various places, use expr instead of
13912 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13913 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13914 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13916 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13917 the wrong patterns between ``case'' and ``esac.'' The previous
13918 code had false positives.

13969 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
13970 enough arguments, similarly as in m4_bpatsubsts.
13972 2005-05-12 Stepan Kasal <kasal@ucw.cz>
13974 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

13982 abbreviations of --version and --debug.
13984 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13986 * doc/autoconf.texi (Autoconf Language): Be more precise about
13987 quoting rules. Problems noted by Stepan Kasal.
13988 Also, throughout this document, be more careful about white space.
13989 "blank", "white space", and "space" all have different meanings
13990 and we should be careful to say what we mean.
13992 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13994 Fix C++ related problems reported by Werner Lemberg.
13995 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

13997 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
13998 avoid problems with C++ and throw.
13999 * tests/compile.at: .cpp, not .cc.
14001 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
14003 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14005 * doc/autoconf.texi (Generic Functions): Typos.
14007 2005-05-02 Gary V. Vaughan <gary@gnu.org>
14009 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
14010 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
14011 set by latest automake.
14013 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
14015 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
14016 outputs 0 on GNU/Linux these days.
14018 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
14020 * doc/autoconf.texi (Autoconf Language): Add more description
14021 about quoting heuristics.
14022 (Limitations of Builtins): Describe "set -" problems.
14024 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14026 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
14029 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
14030 by AC_DEFINE; it was a mistake.
14031 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
14033 2005-04-25 Stepan Kasal <kasal@ucw.cz>
14035 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
14037 2005-04-22 Stepan Kasal <kasal@ucw.cz>
14039 * doc/autoconf.texi (External Software): Quadrigraphs are not
14040 processed correctly in AS_HELP_STRING; avoid this in the examples.
14041 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
14042 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
14043 comment and reduce m4_default([foo], []) to [foo].
14044 (m4_strip): Update the explanation.
14046 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
14048 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
14049 Remove core.conftest.* too; it's generated by Tru64 5.1.
14050 Problem reported by Jennis Pruett.
14051 * lib/autoconf/functions.m4
14052 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
14053 Don't bother to remove core files; AC_RUN_IFELSE should do that
14056 2005-04-19 Stepan Kasal <kasal@ucw.cz>
14058 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

14065 2005-04-15 Stepan Kasal <kasal@ucw.cz>
14067 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
14070 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
14072 * doc/autoconf.texi (External Software, Package Options): Add
14073 examples showing how to implement --with-* and --enable-* options.
14075 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
14077 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
14078 as well as configure.in. Problem reported by Gregorio Guidi.
14080 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
14082 * doc/autoconf.texi (Particular Functions): Use gnulib's current
14083 pattern for alloca snippet.

14093 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
14095 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
14096 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
14098 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14100 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
14101 Merge `-z option' as well for the benefit of Solaris link flags. Pass
14102 whole-archive (-zallextract, -zdefaultextract) options in the hope of
14103 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
14104 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
14106 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
14108 * NEWS: The configure command now warns you if you attempt to use
14109 a directory whose name contains a special character like space,
14111 * doc/autoconf.texi (Installation Directory Variables): Allow
14112 "," in file names. Do not use \@; it's not a portable regexp.
14113 * bin/Makefile.am (edit): Likewise.
14114 * lib/Makefile.am (edit): Likewise.
14115 * tests/Makefile.am (edit): Likewise.
14116 * tests/semantics.at: Likewise.
14117 * tests/torture.at: Likewise.
14118 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
14119 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
14120 * doc/autoconf.texi (File System Conventions): Warn about
14121 unportable file names.
14122 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
14124 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
14125 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
14126 ac_pwd, and quote srcdir.
14127 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
14129 * doc/autoconf.texi: Fix some systematic formatting problems.
14130 ".)" needs a following @: if not at the end of a sentence, and
14131 similarly for "!)". "etc." should be preceded by a comma.
14132 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
14134 2005-03-22 Bruno Haible <bruno@clisp.org>
14136 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
14137 argument is often called 'build-aux'.
14139 2005-03-07 Stepan Kasal <kasal@ucw.cz>
14141 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
14142 macro AC_TRY_LINK is obsolete.
14143 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
14146 2005-02-24 Stepan Kasal <kasal@ucw.cz>
14148 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
14149 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
14150 from a Common Lisp's `cl'.
14151 (AC_PROG_CXX): Behave according to the documentation: don't
14152 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
14153 make the variable CCC precious; use `cl.exe', not `cl'.
14155 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
14156 Alexandre Duret-Lutz <adl@gnu.org>
14158 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
14159 /dev/null, as "configure" shouldn't read stdin, and this insulates
14160 us from problems (e.g., when testing for "cl"). Also, do this
14161 redirection before invoking "hostname" or "uname", and keep the
14162 original input stream available via...
14163 (AS_ORIGINAL_STDIN_FD): ... this new macro.
14164 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
14165 bother with "</dev/null" since it's now done at the top of
14167 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
14168 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
14169 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14170 * doc/autoconf.texi (File Descriptor Macros): New section.

14172 * tests/base.at (Input/Output): New test.
14174 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
14176 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
14177 newline if neither \c nor -n work, as that would output two
14178 newlines. Prefer -n to \c. Reported by Stepan Kasal.
14180 2005-02-12 Stepan Kasal <kasal@ucw.cz>
14182 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
14183 This causes that any required macros inside will get before the if.
14184 * doc/autoconf.texi (autom4te.cache): A typo.
14186 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
14188 Undo previous change, except keep the change to
14189 lib/autoconf/programs.m4 that replaced grep with shell
14190 pattern-matching. This is because net-snmp configure reads stdin.
14191 Reported by Noah Misch.
14193 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
14195 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
14196 from /dev/null, as "configure" shouldn't read stdin, and this
14197 insulates us from problems (e.g., when testing for "cl").
14198 Suggested by Alexandre Duret-Lutz. Also, do this redirection
14199 before invoking "hostname" or "uname".
14200 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14201 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
14202 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
14203 "</dev/null" since it's now done at the top of 'configure'.
14204 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
14205 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14206 Also, replace grep with shell pattern-matching, to save a process.
14208 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
14210 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14211 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
14212 avoid thinking that Allegro Common Lisp's "cl" command is a C++
14215 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
14217 * doc/autoconf.texi (Limitations of Usual Tools): Document that
14218 grep -q isn't portable. Improve grep -s explanation.
14219 Problem reported by Dan Manthey.
14221 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
14223 * doc/autoconf.texi (Special Shell Variables): Clarify
14224 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
14226 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
14228 * doc/autoconf.texi: Use @acronym for DJGPP.
14229 Fix some @code's that should have been @env's, and vice versa.
14230 Sort environment variable names.
14231 Mention that shells no longer inherit IFS.
14232 Don't recommend PATH_SEPARATOR=';' so strongly.
14233 Mention that $RANDOM might expand to the empty string.
14234 "symlink" and "soft link" -> "symbolic link".
14235 Improve mktemp description (reported by Bruno Haible).
14237 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
14239 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
14240 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
14242 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
14245 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
14247 * NEWS: Mention AT_COPYRIGHT.
14249 * tests/local.at (AT_CMP): Use diff directly on input files rather
14252 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
14253 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
14255 2005-02-04 Noah Misch <noah@cs.caltech.edu>
14256 and Paul Eggert <eggert@cs.ucla.edu>
14258 * tests/autotest.at (Empty test suite): New test.
14259 * tests/torture.at (Substitute and define special characters)
14260 (Substitute a 2000-byte string, Define to a 2000-byte string)
14261 (Substitute a newline, Define a newline): New tests.
14263 2005-02-04 Noah Misch <noah@cs.caltech.edu>
14265 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
14266 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
14267 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
14268 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
14269 (Standard regular expressions): New test.
14270 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
14271 excess test name quoting.
14272 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
14273 CPPFLAGS to `configure' instead of setting it in `configure'.
14275 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
14276 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
14279 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
14280 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
14282 * tests/local.at (AT_CMP): New macro.
14283 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
14284 (AC_SAVE_STATE): Move environment grep...
14285 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
14286 (AT_CONFIG_CMP): New macro.
14287 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
14288 * tests/c.at (Extensions): Do not exit early.
14289 * tests/atlocal.in: Inherit $GREP.
14291 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
14292 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
14294 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
14295 (AC_COPYRIGHT): Factor header comment portion out and move into...
14296 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
14297 * lib/autotest/general.at (AT_COPYRIGHT): New macro.

14314 2047-byte limit on line length of portable text files.
14315 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
14316 Use newline as a separator, not space.

14374 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
14375 Update the long comment explaining it.
14377 m4_require no longer writes an ``is required by'' line to the
14378 execution stack. It contains only one bit of non-redundant
14379 information: that the macro was required, not called. And even
14380 this bit is useless in most situations: have you ever met a macro
14381 which both calls and requires the same macro?
14383 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
14384 (_m4_defun_pro_outer): ... only via this macro, for the outermost

14392 * tests/m4sugar.at (m4_require): Expect output without the
14393 ``is required by'' messages.
14395 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
14397 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
14398 rather than x for expr.

14424 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
14426 * doc/autoconf.texi (Limitations of Builtins): Clarify that
14427 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
14429 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14431 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14432 Warn about newline stripping in `` and $(). Update Solaris
14434 (Limitations of Builtins): Use expr "X...", not expr "x...", as

14485 (_m4_divert_n_stack): New macro; the expansion is
14486 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14488 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14489 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14490 stored in _m4_divert_diversion or _m4_divert_dump.
14491 (m4_divert_pop): When the parameter is given, compare the symbolic
14492 name with the last diversion pushed on the stack. Previously, the
14493 current diversion was compared with the numeric value of the
14494 diversion given as the parameter.
14495 (m4_require): If the macro hasn't been expanded yet, call ...
14496 (_m4_require_call): this new macro.

14529 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

14756 (MAINTAINERCLEANFILES): Delete wrapper.in.
14757 (CLEANFILES): Add wrapper.in.
14758 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
14759 the output. Replace each $as_me with a @wrap_program@.
14760 * tests/wrapper.in: Delete it; we always build it.
14762 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
14763 (EXTRA_DIST): Remove autoconf.in.
14764 (CLEANFILES): Add autoconf.in.

14768 2004-12-08 Noah Misch <noah@cs.caltech.edu>
14770 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
14771 PATH members so as to not prepend an empty element. Move a comment.
14772 * Makefile.am (SUBDIRS): Build in `tests' last.
14773 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
14775 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
14777 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
14778 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14779 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14780 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
14782 2004-12-07 Stepan Kasal <kasal@ucw.cz>
14784 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

14796 out the common code to ...
14797 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
14798 value of the #define--default to 1, iff the macro was called
14799 with exactly one parameter.
14801 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
14803 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14804 "char c = '\200';" rather than "char c = 0x80;" as the
14805 latter doesn't conform to the strict C standard due to
14806 overflow on signed char hosts.
14808 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14809 to -qlanglvl=ansi. We don't want to disable extensions.

14886 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
14888 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
14889 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS

14911 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
14913 Fix problems reported by Andreas Buening in:
14914 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
14915 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
14917 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

14920 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14922 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14923 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14924 (trivial change). Problem and patch reported by Andrew Church in:
14925 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14927 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14957 Remove ansi2knr.c; nobody uses it.
14958 (ansi2knr.c-url_prefix): Remove.
14959 (cvs-update): Fix test for failure. I don't know why it ever
14962 * doc/autoconf.texi: Update URLs, some of which went stale.
14963 Use @uref rather than @href.
14965 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14966 handle "--" as per POSIX. Suggested by Paul Pogonyshev.

14980 Use "file name" rather than "filename" or "path",
14981 to be consistent with the terminology of the GNU coding standards.
14983 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14985 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14986 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14987 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14988 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14990 More fixes to support spaces in the name of the build directory.
14991 This isn't a complete fix but it's an improvement.
14993 * bin/autoconf.as (autom4te_options): New var.
14994 Use it instead of appending to AUTOM4TE, so that we can allow
14995 spaces in the build directory's absolute name.
14996 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14997 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14998 AT_CHECK_NOESCAPE): Likewise.

15011 and isnan. From a suggestion by Kevin Ryde.
15013 * lib/Autom4te/General.pm (END): Return correct exit status even
15014 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
15016 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
15018 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
15019 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
15020 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

15031 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
15033 * lib/autom4te.in (Automake-preselections): Preselect

15044 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
15046 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
15047 with pdksh, too. Problem reported by Patrick Welche via
15049 * doc/autoconf.texi (Shellology): Note that set -o posix is
15050 useful for pkdsh, too.
15052 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
15054 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
15055 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
15056 Don't fail if ENV or BASH_ENV is readonly.
15057 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
15058 etc. are read only. Problem reported by Ludovic Courtes.
15060 2004-06-23 Noah Misch <noah@cs.caltech.edu>
15062 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
15063 zsh, disable GLOB_SUBST to avoid backslash handling problems.
15066 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
15068 * doc/autoconf.texi (File System Conventions): Warn about
15069 names like "aux". Problem reported by Eric Blake.
15071 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
15072 by zero instead of array size, so that we can use any arithmetic
15073 constant expression (instead of requiring an integer constant
15074 expression). This allows us to test expressions like DBL_MAX <
15075 LDBL_MAX, which didn't conform to the C standard using the old
15077 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
15078 now that we can do floating-point tests at compile time.
15080 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
15082 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
15083 and LDBL_EPSILON, as the resulting expression isn't an
15084 integer constant expression and violates the C standard.
15085 Problem reported by Nelson H. F. Beebe. Also, check
15086 for "L" suffix, and check that long double doesn't have
15087 worse range or precision than double, that mixed-mode
15088 arithmetic doesn't generate a diagnostic, that double
15089 constants fit in long double.
15091 2004-06-03 Kevin Ryde <user42@zip.com.au>
15093 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
15094 malloc(0) and realloc(NULL,size).
15096 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
15099 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
15101 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
15102 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
15105 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
15107 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
15108 can be rewritten using if-then-else. Suggested by Bruno Haible.
15110 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
15112 * doc/autoconf.texi (testsuite Scripts): Fix typo.
15113 Problem reported by Stepan Kasal.
15115 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
15117 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
15118 change). Patch reported by Ralf Wildenhues in
15119 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
15121 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
15122 function F exists if the compiler and linker let you compile an
15123 expression like (F != 0). Recent versions of GCC optimize away
15124 the reference to F in that case, since every function address must
15125 be nonzero, so the link succeeds even if F does not exist.
15126 Problem reported by Manu in
15127 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
15129 * doc/autoconf.texi (Systemology): Standardize on the spelling of
15130 "Unix". Many uses changed.

15134 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
15136 * lib/autom4te.in (Automake-preselections): Preselect
15137 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
15139 2004-05-19 Kevin Ryde <user42@zip.com.au>
15141 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
15142 referencing AC_FUNC_STRERROR_R.
15144 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
15145 note pessimistic assumption when cross compiling.
15147 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
15149 * doc/autoconf.texi (Limitations of Make): Note that BSD make
15150 (until 2004) invoked subcommands with sh -e, contra POSIX.
15151 Reported by Kevin Ryde.
15153 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
15155 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
15156 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
15157 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
15158 `test -f " /usr/bin/grep"', which _always_ failed.
15159 (AC_PROG_SED): Ditto bogus PATH fix.
15160 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
15161 requires that grep correctly supports _multiple_ `-e' options, rather
15162 than stating only that grep should accept `-e'.
15164 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
15166 Port to C99, which requires that 'exit' be declared.
15168 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
15169 to ensure that stdlib.h is included.
15170 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
15171 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
15172 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
15173 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
15174 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
15175 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
15176 when using 'exit' in a test; C99 requires that 'exit' be declared.
15178 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
15180 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
15181 now prefers 'grep' implementations that accept -e.
15182 (Limitations of Usual Tools): Describe problems of traditional
15183 egrep and fgrep with long input lines, and of traditional grep
15185 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
15186 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
15187 All callers changed. Append /usr/xpg4/bin to the PATH, for
15189 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
15190 the user with complaints about multiple -e options.
15191 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
15192 Define it with AC_PROG_GREP.
15193 * configure.ac (AC_PROG_GREP): Add.
15194 * lib/freeze.mk (GREP): New macro.
15196 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
15198 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
15199 a possible candidate only after all others fail, rather than
15200 consulting it first. This improves backward compatibility by
15201 better reflecting the way shell selection occurred in previous
15202 versions of Autoconf, and should help to avoid triggering latent
15203 problems in other packages, such as the one in Automake where zsh
15204 is not handled robustly:
15205 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
15206 Although it is not Autoconf's responsibility to work around
15207 problems in Automake, it nevertheless makes sense to avoid
15208 introducing unnecessary incompatibilites.

15211 Gary V. Vaughan <gary@gnu.org>
15213 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
15214 how deeply nested we are when a suitable tool is found, set the
15215 ac_path_TOOL_found flag.
15216 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
15217 nested we are in this macro. Break out of all 3 nested loops if
15218 ac_path_TOOL_found is set.
15220 2004-04-21 Gary V. Vaughan <gary@gnu.org>
15222 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
15223 of the _AS_PATH_WALK loop too if GNU flavor is found.

15227 * doc/autoconf.texi (Limitations of Make): Update documentation
15228 for `$<'. New entry `Long lines', based on a report from Simon
15229 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
15230 paragraph about DJGPP, based on a mail from Richard Dawe.
15232 2004-04-20 Paul Eggert <eggert@twinsun.com>
15234 * tests/c.at (C keywords): Don't assume that GCC supports
15235 "restrict" and "inline", as sufficiently-old GCC versions do not
15236 (also, GCC configured to be in pedantic C89 mode does not).
15237 Problem reported by Sumit Pandya in:
15238 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
15240 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
15241 consider -g to work if it generates warnings when plain compiles
15242 don't. Problem reported by Braden McDaniel in:
15243 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

15256 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
15257 best tool so far counter rely on the tool path variable name to
15258 avoid checks for one tool being affected by the results of running
15259 the length check on a previous tool.
15261 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
15262 match expression argument, as different greps have different
15263 regular expression flavours.

15269 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
15271 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
15272 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
15274 2004-03-29 Paul Eggert <eggert@twinsun.com>
15276 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
15277 Types, Specific Compiler Characteristics, System Services,
15278 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
15279 etc. consistently instead of 'long', 'short', 'unsigned' etc.

15292 2004-03-28 Paul Eggert <eggert@twinsun.com>
15294 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
15295 now defines HAVE_DECL_TZNAME if it is declared, when
15296 HAVE_STRUCT_TM_TM_ZONE is not defined.
15297 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
15298 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

15367 * bin/Makefile.am (edit): Don't use $< in a context where
15368 POSIX doesn't require support for it. Use $@.in instead.
15369 Problem reported by Anthony N. Frasso in
15370 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

15386 Fix a dependencies problem, stemming from a Autoconf 2.59 build
15387 problem on QNX reported by Stephen Rasku in
15388 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
15390 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
15391 $(m4sh_m4f_dependencies); this removes a FIXME.
15392 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
15393 (MAINTAINERCLEANFILES): Split into pieces,
15394 one per related section. Add $(srcdir)/wrapper.in.
15396 2004-02-09 Paul Eggert <eggert@twinsun.com>
15398 * doc/autoconf.texi (Setting Output Variables): Emphasize that
15399 AC_SUBST provides no portable way to escape literal newlines.
15401 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
15402 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
15403 Darwin uses -lcrt2.o and there's little point to cataloging all
15404 the system variants. Partial fix reported by Andreas Waechter in:
15405 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

15421 the behavior of the third argument.
15422 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
15423 correctly the behavior of the third argument. Document
15424 what the three macros that AU_DEFUN defines do. Fix

15432 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
15433 (AS_INIT): Output shell initialization there. Removed optional
15434 parameter. Expand _AS_SHELL_FN_SPY.

15443 (_AS_RUN): Move it here, support testing with eval.
15444 (AS_REQUIRE_SHELL_FN): Require shell functions when
15446 (_AS_LINENO_WORKS): Put around braces, we do not
15447 trigger the bash bug anymore.
15448 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
15449 use AS_INIT_WITH_SHELL_FN.
15450 * bin/autoconf.in, tests/wrapper.in: Regenerated.
15452 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

15458 (AU_DEFUN): Honor the third parameter, create autoupdate
15459 macros with AU_DEFINE.
15460 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
15461 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

15480 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
15481 2003 (except 1997) to the list of copyright years. This undoes
15482 the 2003-05-22 change, which removed the older years from the list.
15483 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

15489 grep or ggrep program in PATH that accepts as long lines as
15491 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
15493 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
15494 egrep and fgrep respectively if $GREP -E/-F don't work.
15495 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15496 _AC_PROG_GREP, and AC_PROG_SED.
15497 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
15498 longest input length accepted by a command.

15527 2004-01-26 Paul Eggert <eggert@twinsun.com>
15529 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15530 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15531 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15532 not <inttypes.h>. Problem reported by Tim Mooney in
15533 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15534 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15537 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15538 otherwise "make check" fails because it forbids cmp (I guess
15539 because cmp treats files as binary on DOS-like systems).
15541 * tests/mktests.sh: Update copyright date to 2004, since some tests
15542 have changed in 2004.
15544 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15546 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15547 non-truncating sed or gsed program in PATH.
15548 * tests/acprograms.at: Add it.
15549 * doc/autoconf.texi (Particular Programs): Document it.
15552 2004-01-15 Paul Eggert <eggert@twinsun.com>
15554 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15555 -std1 disables some useful extensions on Tru64. Problem reported
15556 by N. Lichtmaier in

15559 2004-01-14 Paul Eggert <eggert@twinsun.com>
15561 * doc/autoconf.texi (Programming in M4sh): Document that
15562 AS_MKDIR_P succeeds if the destination is a symbolic link
15563 to an existing directory.
15564 (Limitations of Usual Tools): Note that mkdir -p might not
15565 succeed on symlinks to directories.
15567 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15569 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15570 * bin/autoheader.in: Grammar fix in message.
15571 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15572 Test for dir before calling mkdir -p. (trivial changes)
15574 2004-01-13 Eric Blake <ebb9@byu.net>
15576 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and

15579 2004-01-10 Jim Meyering <jim@meyering.net>

15583 2004-01-09 Paul Eggert <eggert@twinsun.com>
15585 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15586 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15587 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15588 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15589 AC_COMPILE_IFELSE, since we now assume our caller invokes
15590 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15591 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15592 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15593 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15595 2004-01-07 Paul Eggert <eggert@twinsun.com>
15597 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15598 `"'...'"`, as it's confusing (and I suspect it may not work on
15599 some platforms). The code was incorrect anyway, as it assumed
15600 that \$ evaluated to itself in that context. Reported by
15601 Alexandre Duret-Lutz.
15603 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15605 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15606 and _LT_AC_TAGCONFIG.

15616 Remove warning against "rm -fr" introduced yesterday; it
15619 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
15620 autoscan, autoupdate, ifnames): Don't use chmod -w.

16122 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
16123 (ifnames): chmod -w.
16124 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
16125 executables, not bin/ executables! Otherwise all the magic needed
16126 to find non installed files is turned off. This caused a failure
16127 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
16128 as found in its environment (sent by tests/autoreconf): pointing
16129 to bin/autom4te that could not find its files.
16130 * tests/mktests.sh: Force the replacement of generated files, for
16131 the sake of "mv" program that are interactive when overwriting a
16133 * config/install-sh: Upgrade from CVS Automake.
16135 2003-09-23 Paul Eggert <eggert@twinsun.com>

16138 versus test -L issues.
16140 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
16141 Paul Eggert <eggert@twinsun.com>
16143 Trivial change to support GCC's configuration procedure.
16144 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

16174 From Peter Hendrickson.
16176 2003-09-10 Akim Demaille <akim@epita.fr>
16178 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
16179 willing to edit the output files.
16181 2003-09-10 Akim Demaille <akim@epita.fr>
16183 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
16184 and AC_FC_FREEFORM.
16185 * tests/mktests.sh: Skip AC_FC_SRCEXT.
16186 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
16188 2003-09-09 Akim Demaille <akim@epita.fr>
16190 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
16191 Reported by Gary Vaughan.

16203 From a suggestion by Ian Lance Taylor in
16204 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
16206 2003-09-05 Paul Eggert <eggert@twinsun.com>
16208 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
16209 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
16211 2003-09-04 Akim Demaille <akim@epita.fr>
16213 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

16218 * bin/autom4te.in: Use &fatal where more appropriate than &error.
16219 (freeze): When exiting, use $exit_code.

16222 2003-09-04 Akim Demaille <akim@epita.fr>
16224 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
16226 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
16228 Add support for newer Fortran dialects. The F77 interface is
16229 unchanged, and continues to support Fortran 77. New FC macros
16230 correspond to all the old F77 macros, with output variables FC,
16231 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
16232 available dialect, but older dialects can be specified. There are
16233 new macros AC_FC_SRCEXT to set the source extension, and
16234 AC_FC_FREEFORM to accept free-form source files.
16236 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
16238 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
16239 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

16255 Rewrite in terms of the above.
16256 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
16257 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

16264 Document problems with timestamp resolution that 'make', 'cp -p', and
16267 2003-08-27 Akim Demaille <akim@epita.fr>
16269 * tests/m4sugar.at (cross_warning): Make sure to enable the
16270 output, so that we can track spurious m4sugar output.
16271 * tests/local.at: Require 2.57.
16272 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
16273 are defaulted by AT_CHECK anyway.
16274 Use AT_CHECK_AUTOM4TE.
16275 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
16278 2003-08-27 Akim Demaille <akim@epita.fr>

16281 when -Wobsolete is set.
16282 Set it on by default.

16334 * bin/autom4te.in: Adjust to output the call stack.
16335 * tests/m4sugar.at (m4@&t@_warn): Adjust.
16337 2003-08-22 Akim Demaille <akim@epita.fr>

16344 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
16345 (&verbose): Remove.

16358 * lib/Autom4te/General.pm: Don't export error: you don't own it.
16360 2003-08-21 Akim Demaille <akim@epita.fr>
16362 First stab at preserving warnings between calls to autom4te,
16363 including when the cache is used.
16365 There are still several issues: (i) there are too many runs of m4
16366 (one for include, one for warnings, and some more), (ii) warnings
16367 spreading on several lines are not handled gracefully, (iii) the
16368 code meant to have the call stack display for errors does not work
16369 (its handling should move from m4 to autom4te).
16371 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
16373 (@preselect): Add m4_warn.
16374 ($exit_status): Remove, use $exit_code.
16375 ($help): Use Autom4te::ChannelDefs::usage.
16376 (&handle_m4): No longer define the m4_warnings.
16377 At each run, extract and report the warnings.
16378 Always cache the result, including if the exit status is on
16379 failure, since if nothing changes, we should result in the same
16380 failure, hence we can use the cache.
16381 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
16382 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
16384 (m4_warn): Redefine as a do-nothing: it is its invocation that
16385 matters, as warnings are now reported via traces.
16386 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
16387 the contents of m4_warn: make it _call_ m4_warn, so that tracing
16388 the latter reveals calls to the former.
16392 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
16394 2003-08-21 Akim Demaille <akim@epita.fr>
16396 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

16404 (&parse_warnings): Accept a list of warning requests.
16405 (&usage): Return a string, not a side effect.
16406 (cross): New warning category.

16410 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
16411 (&require_configure_ac): Accept an optional directory argument.
16412 ($configure_ac): Remove.
16413 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
16414 (&catfile): Remove.
16415 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
16416 * bin/autoscan.in: Adjust.
16418 2003-08-20 Akim Demaille <akim@epita.fr>
16420 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
16421 Reported by Alexandre Duret-Lutz.
16423 2003-08-20 Akim Demaille <akim@epita.fr>
16425 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
16426 * bin/autom4te: Adjust.
16427 In particular, be Autoconf tools are really silent when properly
16428 working, bind the verbosity of the 'note' channel to $verbose.
16429 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
16430 (&xsystem, &contents): Remove, since they are exported by...
16431 * lib/Autom4te/FileUtils.pm: this.
16433 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
16434 * lib/Autom4te/FileUtils.pm: here.
16436 2003-08-20 Akim Demaille <akim@epita.fr>
16438 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

16491 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
16492 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
16493 shorter column three. Add DESCRIPTION to log file content.
16495 2003-08-13 Derek Price <derek@ximbiot.com>
16497 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
16500 2003-08-12 Derek Price <derek@ximbiot.com>

16513 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug

16522 2003-07-07 Paul Eggert <eggert@twinsun.com>
16524 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
16525 inside '#ifndef __cplusplus'. Problem reported by
16528 2003-07-06 Bill Clarke <llib@computer.org>
16530 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
16531 'long', not 'int', for benefit of Sun's recent C++ compilers
16532 (trivial change). See:
16533 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

16549 From Gareth McCaughan.
16551 2003-06-23 Akim Demaille <akim@epita.fr>
16553 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16554 not all of them. This fixes 1. the fact that when testing
16555 Autoconf there are many many config.log, 2. the incorrect use of
16556 top_srcdir to find config.log.
16557 Don't mix the detailed output of failed test with the summary of
16558 failures. Rather, append detailed log afterwards.
16560 2003-06-23 Akim Demaille <akim@epita.fr>
16562 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

16577 * tests/local.at: here.
16578 * tests/Makefile.am: Adjust.
16579 * doc/autoconf.texi (testsuite Scripts): Adjust.
16581 2003-06-21 Kevin Ryde <user42@zip.com.au>
16583 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
16584 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
16585 ensuring we add -std1 for full-ANSI.
16587 * doc/autoconf.texi (hdrindex): New macro.
16588 Add index entries for portability of various standard header files.
16590 2003-06-20 Akim Demaille <akim@epita.fr>

16651 63 for version mismatches.
16653 2003-05-23 Akim Demaille <akim@epita.fr>
16655 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16656 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16657 the middle of a line).
16658 * lib/m4sugar/m4sugar.m4: Likewise.
16659 Remove useless spaces in comments.
16661 2003-05-23 Akim Demaille <akim@epita.fr>
16663 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

16665 difference with a plain failure.

16675 Paul Eggert <eggert@twinsun.com>
16677 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16678 Remove `#include <stdlib.h>' from the list; we should never
16679 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16680 resulting namespace pollution would cause other tests to fail.
16681 Configure scripts run with some older versions of g++ and HP's
16682 aCC would fail due to such an #include. Problems reported by
16683 Matthew Mueller in <http://bugs.debian.org/120704> and by
16685 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16686 In the test, use the test declaration before including <stdlib.h>,
16687 as that's closer to how it'll be used.
16689 2003-05-23 Akim Demaille <akim@epita.fr>
16691 * doc/autoconf.texi (Header Portability): ucred.h.
16694 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16696 Overhaul Autotest's logging: generate separate log files
16697 in testsuite.dir/NNN/testsuite.log, and append them to
16698 testsuite.log instead of re-running the test verbosely.
16700 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16701 file descriptor, write 0 to at_status_file instead of setting
16702 at_status=0, initialize some new variables (at_status_file,
16703 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16704 to rerun the tests, instead append the at_group_log to the
16705 at_suite_log when a test fails.
16706 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16707 with the AS_MESSAGE_LOG_FD redirected to stdout.
16708 (AT_CLEANUP): save the output status in $at_status_file
16709 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16710 its original place.
16711 (AT_CHECK): since tests are run with a redirected stdout,
16712 and used to be re-run in verbose mode, turn some $at_verbose
16713 into echo, and don't redirect the output of testing stdout
16716 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16717 the name of the debugging directory and information about

16837 2003-05-06 Akim Demaille <akim@epita.fr>
16839 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16840 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16841 by aclocal.m4 is changed it might require the importing of another
16842 m4 extension file, i.e., aclocal must be run.
16844 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16845 (&parse_args): Use --force with aclocal if required and supported.

16859 2003-04-29 Derek Price <derek@ximbiot.com>
16861 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16862 seperator with m4_append_uniq(). It doesn't work.
16863 (AT_CLEANUP): Add `;' to end of at_help_all.
16864 (AT_INIT): Allow --keywords to be specified more than once. When
16865 grepping $at_help_all for keywords, use the field and keyword

16867 to support the new --keywords behavior.

16871 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16872 align better with others. I also made some of the individual
16873 entries on one line, for brevity and to make it easier for me to

17081 2003-02-20 Klee Dienes <kdienes@apple.com>
17083 * bin/autoreconf.in (autoreconf_current_directory): Properly
17084 handle an empty aclocal.m4.

17089 $ac_prefix_program.
17092 2002-12-23 Paul Eggert <eggert@twinsun.com>
17094 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
17095 innocuous variant befor including <limits.h> or <assert.h>. This
17096 works around a bug reported by Albert Chin: HP-UX 11i
17097 (and earlier versions) have a <limits.h> that declares
17098 gettimeofday and many other functions.
17100 2002-12-03 Paul Eggert <eggert@twinsun.com>
17104 * NEWS, configure.ac: Update version.
17106 * doc/fdl.texi: Upgrade to FDL version 1.2.
17108 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
17109 nontrivially in main's body, so that f's external declaration is
17110 not optimized away in AIX. This should fix the bug reported by
17112 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
17114 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
17115 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
17116 defined, to support freestanding compilers. This should fix the
17117 bug reported by Momchil Velkov in
17118 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
17120 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
17121 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
17122 obsolete AC_CHECK_TYPE. The missing empty arg was reported
17123 by Simon Josefsson in
17124 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
17126 * Makefile.maint (www-gnu): New macro.
17127 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

17132 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
17133 \(.*\) match is too long and there is something more to be checked.

17152 Update from masters.
17154 2002-11-14 Akim Demaille <akim@epita.fr>
17156 * Makefile.maint: Sync with Bison, i.e.:
17157 (po-check): Scan .l and .y files instead of the
17158 .c and the .h files that they generate. This fixes the bug
17159 reported by Tim Van Holder in:
17160 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
17161 Look for N_ as well as for _. Try to avoid matching #define for
17165 2002-11-14 Akim Demaille <akim@epita.fr>
17167 * doc/autoconf.texi (C Compiler): Compiling several files at once.
17168 From Paul Eggert and Albert Chin-A-Young.
17170 2002-11-14 Akim Demaille <akim@epita.fr>
17172 * doc/autoconf.texi (C Compiler): Solitary backslashes.
17173 From Paul Eggert and Albert Chin-A-Young.
17175 2002-11-14 Kevin Ryde <user42@zip.com.au>
17177 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
17178 than assigning in main, to avoid HP cc +O3 optimizing it away.
17180 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
17182 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
17183 option. Process --recheck after parsing all options. Pass -q
17184 option to configure on --recheck.
17185 (AC_OUTPUT): Pass -q from configure to config.status.
17186 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
17187 arguments to record.
17188 * doc/autoconf.texi (config.status Invocation): Document
17189 config.status -q option.
17191 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
17193 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
17194 Makefile.in if Makefile.am exists.
17195 (output): Strip `.am' from Makefiles. Don't
17196 output AC_CONFIG_FILES if no Makefiles were found.

17216 Reported by Ezra Peisach.
17218 2002-11-05 Akim Demaille <akim@epita.fr>
17220 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
17222 We _have_ to stop using the old compatibility scheme that tried to
17223 avoid useless backslashes because Libtool 1.4.3 contains a
17224 AC_DEFINE([error_t], [int],
17225 [Define to a type to use for \`error_t' if it is not
17226 otherwise available.])
17227 We _have_ to quote the single quote and backslashes with \. The
17228 old compatibility scheme saw that ` was backslashed, and therefore
17229 did not quote the single quote. Hence before this patch, Autoconf
17230 was not compatible with Libtool.
17232 2002-11-04 Paul Eggert <eggert@twinsun.com>
17234 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

17254 * doc/autoconf.texi (autoreconf Invocation): Adjust.

17275 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
17276 Make variable, not a shell variable.
17277 Suggested by Bruno Haible.
17279 2002-10-31 Akim Demaille <akim@epita.fr>
17281 * bin/autom4te.in (load_configuration): Reject #args out of any
17284 2002-10-31 Akim Demaille <akim@epita.fr>

17304 Problem reported by Bruno Haible.

17308 * doc/autoconf.texi (Header Templates): Put also in words what the

17310 (Customizing autom4te): s/--cache=/--cache /.
17312 2002-10-29 Akim Demaille <akim@epita.fr>
17314 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

17587 missing included files _are_ errors.
17588 Thanks to Alexandre Duret-Lutz.
17589 * tests/tools.at (autom4te cache): Adjust.
17590 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.
17591 (AT_CHECK_M4SUGAR): Use it.
17592 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17594 * tests/tools.at (autom4te): Now it does exit 1.
17596 2002-10-17 Akim Demaille <akim@epita.fr>
17598 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
17599 Fixes the `AC_ARG_VAR' test failures.
17600 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
17601 * lib/freeze.mk (check-forbidden-patterns): New.
17602 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
17603 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
17604 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
17606 Reported months ago by H. Merijn Brand.
17608 2002-10-17 Akim Demaille <akim@epita.fr>
17610 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
17612 2002-10-16 Paul Eggert <eggert@twinsun.com>
17614 * Makefile.maint (wget_files): Remove ansi2knr.c.
17615 (ansi2knr.c-url_prefix): Remove.
17617 2002-10-16 Akim Demaille <akim@epita.fr>
17619 Because of caching, some files that no longer exist and are no
17620 longer required can still cause errors.
17621 Reported by Alexandre Duret-Lutz.
17623 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
17624 to frozen files in @ARGV, as @ARGV must remain being a list of
17625 files. Rather, at M4 call sites, use this...
17626 (&files_to_options): New function.
17627 (&freeze): Use &error.
17628 (&up_to_date): If a file that was included according to the cache
17629 is no longer there, then the output is out dated.
17630 (&main): Don't even check whether a file is up to date is anyway
17632 * tests/tools.at (autom4te cache): New.
17634 2002-10-16 Akim Demaille <akim@epita.fr>
17636 * bin/autoconf.as: Kill dead options.
17637 * bin/autoupdate.in (&parse_args): Kill old options.
17638 * bin/autoreconf.in (&parse_args): Remove dead options.
17640 (&autoreconf): Report the directories we enter *and leave*, so
17641 that error messages can be easily located, and use GNU Make
17642 format, so that Emacs' compile mode understands us.
17643 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17644 if some file was changed instead of `print'.
17645 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
17646 (&parse_args): Remove the dead options.
17647 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
17648 autoheader's quiet mode.
17649 (AT_CHECK_AUTOUPDATE): Likewise.
17650 * tests/tools.at (autoupdate): Adjust.
17651 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
17653 2002-10-11 Akim Demaille <akim@epita.fr>
17655 No longer use CPP to check for the existing of headers: use CC to
17656 check for compilability.
17658 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
17659 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
17660 (_AC_CHECK_HEADER_NEW): Rename as...
17661 (AC_CHECK_HEADER): this.
17663 * lib/autotest/general.m4 (AT_INIT): Include the failed test
17664 numbers in the Subject suggestion.
17666 2002-10-11 Akim Demaille <akim@epita.fr>
17668 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
17669 Suggest using AC_CHECK_DECLS instead.
17671 2002-10-11 Akim Demaille <akim@epita.fr>
17673 * tests/torture.at (AC_ARG_VAR): Have configure report the value
17676 2002-10-11 Akim Demaille <akim@epita.fr>
17678 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
17679 file name to enable parallel executions.
17680 From Sam Varshavchik.
17682 2002-10-08 Akim Demaille <akim@epita.fr>
17684 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17685 aclocal invocation, as Gettext macros might not be visible to
17687 Instead of blindly running autopoint, scan configure.ac (not the
17688 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17689 Reported by Paul D. Smith.
17691 2002-10-08 Paul Eggert <eggert@twinsun.com>
17693 Work around problems found when POSIXLY_CORRECT=1 is set.
17694 None of this seems to have anything to do with POSIX, really,
17695 but it's how Perl getopt works.
17696 * bin/autom4te.in (parse_args): Configure GetOpt with
17698 * doc/autoconf.texi (Invoking autom4te):
17699 --warning -> --warnings.
17700 * lib/autom4te.in: --warning -> --warnings.
17702 2002-09-28 Akim Demaille <akim@epita.fr>
17704 * doc/autoconf.texi (autom4te.cache): New section.
17706 2002-09-28 Akim Demaille <akim@epita.fr>
17708 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
17709 (Automake-preselections): Update.
17710 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
17712 2002-09-28 Akim Demaille <akim@epita.fr>
17714 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
17715 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
17716 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17717 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
17719 2002-09-28 Akim Demaille <akim@epita.fr>
17721 * tests/torture.at (Configuring subdirectories): Be robust to
17722 users who use config.site to require for a cache: in this case,
17723 the two last configure runs, using two different sets of
17724 arguments, trigger a legitimate error.
17726 2002-09-28 Akim Demaille <akim@epita.fr>
17728 * tests/m4sh.at (Functions Support, Functions and return Support):
17731 2002-09-28 Akim Demaille <akim@epita.fr>
17733 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
17734 autoheader are Perl programs.
17735 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
17736 (autom4te): Specify that the sources are in the $srcdir.
17737 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17739 2002-09-28 Akim Demaille <akim@epita.fr>
17741 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
17742 (tm_zone): Move their rules to...
17743 * lib/autoconf/types.m4: here, using AN_ macros.
17744 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
17745 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
17746 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
17747 * lib/autoconf/programs.m4: here.

17757 that were listed in the original autoscan.list.
17758 * lib/autoconf/headers.m4: Similarly with headers.
17759 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
17760 (.m4.m4f): Don't pass --prepend-include, since that's done by
17761 tests/autom4te itself.
17762 * lib/autoscan/Makefile.am: Include freeze.mk.
17763 (autoscan.list): New target --this file is no longer a source.
17764 (autoscan.pre): New file.
17766 2002-09-28 Akim Demaille <akim@epita.fr>
17768 * bin/autoscan.in (@kinds): Make them singular.
17770 (&init_tables): When --debug, report the list of rules to ease
17771 tracking changes in autoscan.list.
17772 * lib/autoscan/autoscan.list (function): Strip comments, sort.
17774 2002-09-28 Akim Demaille <akim@epita.fr>
17776 * lib/autoscan/functions, lib/autoscan/headers,
17777 * lib/autoscan/identifiers, lib/autoscan/makevars,
17778 * lib/autoscan/programs: Merge into...
17779 * lib/autoscan/autoscan.list: this.
17780 * bin/autoscan.in (&init_tables): Adjust.
17782 2002-09-28 Akim Demaille <akim@epita.fr>
17784 * lib/autoscan/functions, lib/autoscan/headers,
17785 * lib/autoscan/identifiers, lib/autoscan/makevars,
17786 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
17787 `functions' line is now prefixed with `function:'.
17788 * bin/autoscan.in (&init_tables): Adjust.
17790 2002-09-28 Akim Demaille <akim@epita.fr>
17792 From now on, autoscan files must always map a macro name to a
17793 word: there is no `default' macro for autoscan.
17795 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17797 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17800 2002-09-28 Akim Demaille <akim@epita.fr>
17802 * bin/autoscan.in (%c_keywords): Remove.
17803 (&used): Keep only track of the words we might be interested in.
17804 (&output_kind): It is no longer needed to look for non active
17807 2002-09-27 Akim Demaille <akim@epita.fr>
17809 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
17810 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
17811 * lib/autoscan/functions: Adjust.
17812 * doc/autoconf.texi (Particular Functions): Adjust.
17814 2002-09-27 Akim Demaille <akim@epita.fr>

17818 Thanks to Bill Moseley and Paul Eggert.
17819 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17820 the tmpdir must be created.
17821 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17822 dir be in the build tree, instead of $TMPDIR.
17824 2002-09-27 Akim Demaille <akim@epita.fr>
17826 * bin/autoscan.in: Improve the comments.
17827 (&parse_args): Drop obsolete undocumented options.
17828 (&output_kind): Output warnings.
17829 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

17832 2002-09-26 Akim Demaille <akim@epita.fr>
17834 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
17835 Reported by Ralf Corsepius.
17836 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17838 2002-09-26 Akim Demaille <akim@epita.fr>
17840 Single suffix rules and seperated dependencies are not portable.
17842 * doc/autoconf.texi (Installation Directory Variables): Update.
17843 (Limitations of Make): Some about `Single Suffix Rules and
17844 Separated Dependencies'.
17845 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17846 (ifnames, autoscan, autom4te): Un-factor into several rules.
17848 2002-09-25 Paul Eggert <eggert@twinsun.com>
17850 * BUGS (Interoperability bugs): New section. Mention libtool
17851 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17853 2002-09-24 Paul Eggert <eggert@twinsun.com>
17855 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17856 make handles suffix-rules differently from GNU make.
17858 * bin/Makefile.am (SUFFIXES, .in): Remove.
17859 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17860 Move the body of the old .in rule here.
17862 2002-09-16 Akim Demaille <akim@epita.fr>
17864 i960 compilers create `b.out' files by default.
17865 Reported by Ralf Corsepius.
17867 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17868 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17870 2002-09-13 Paul Eggert <eggert@twinsun.com>
17872 * doc/autoconf.texi (Particular Headers): Remove obsolete
17873 reference to `struct timezone' in the description of
17876 2002-09-13 Akim Demaille <akim@epita.fr>
17880 * config/config.sub, config/config.guess: Update.
17881 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
17882 * Makefile.am: Adjust.
17884 2002-09-13 Akim Demaille <akim@epita.fr>
17886 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17887 reading config.log when the compiler is rejected.
17888 Suggested by Guido Draheim.
17890 2002-09-13 Akim Demaille <akim@epita.fr>
17892 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17893 (chdir_init) might hang when stat'ing mounted directories.
17894 Reported by Vance Shipley.
17896 2002-09-12 Akim Demaille <akim@epita.fr>
17898 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17901 2002-09-12 Akim Demaille <akim@epita.fr>
17903 * doc/autoconf.texi (Defining Symbols): Present two different
17904 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17905 difference between 1 argument calls, and 2-3 argument calls.
17907 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17909 * doc/autoconf.texi: Review grammar and punctuation.
17911 2002-09-11 Paul Eggert <eggert@twinsun.com>
17913 * doc/autoconf.texi: Fix minor formatting, spelling, and
17915 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17916 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17919 2002-09-11 Akim Demaille <akim@epita.fr>
17921 * doc/autoconf.texi (Questions): Rename as...
17923 (Defining Directories): New.
17925 2002-09-09 Akim Demaille <akim@epita.fr>
17927 * doc/autoconf.texi (Making testsuite Scripts): Update.
17928 Suggested by Nishio Futoshi.
17930 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17932 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17933 plain `@' is wanted.
17935 2002-09-09 Akim Demaille <akim@epita.fr>
17937 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17938 `duplicates', since the algorithm was too naive and could keep
17939 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17940 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17941 Reported by Ralf Corsepius.
17942 * tests/torture.at (Configuring subdirectories): Exercise these
17945 2002-09-09 Akim Demaille <akim@epita.fr>
17947 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17948 looking for a replacement file.
17949 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17950 directory is relative.
17951 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17952 directory definition.
17953 Reported by Andreas Schwab and Jim Meyering.
17955 2002-09-06 Akim Demaille <akim@epita.fr>
17957 * doc/autoconf.texi (Setting Output Variables): Clarify what
17958 precious variables are.
17959 Suggested by Pontus Skoeld.
17961 2002-09-05 Akim Demaille <akim@epita.fr>
17963 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17964 (ifnames, autoscan, autom4te): Since we don't only depend on
17965 configure.ac variables (such as VERSION etc.), but also on prefix
17966 and so forth, depend on Makefile, not configure.ac.
17967 Reported by Alexandre Duret-Lutz.
17968 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17970 2002-09-05 Kevin Ryde <user42@zip.com.au>
17972 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17973 doesn't seem to be confined to ia64, just say "some versions".
17975 2002-09-04 Akim Demaille <akim@epita.fr>
17977 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17979 * Makefile.am (maintainer-clean-local): Remove.
17980 (MAINTAINERCLEANFILES): Remove COPYING.
17982 2002-09-03 Paul Eggert <eggert@twinsun.com>
17984 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17985 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17988 2002-09-03 Akim Demaille <akim@epita.fr>
17990 * configure.ac: Bump to 2.53d.
17991 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17992 as of today, on Automake's team suggestion.
17994 2002-09-03 Akim Demaille <akim@epita.fr>
17998 2002-09-02 Akim Demaille <akim@epita.fr>
18000 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
18002 * configure.ac: Disable SITE_MACRO_DIR.
18004 2002-09-02 Jim Meyering <meyering@lucent.com>
18006 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
18007 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
18008 Also, tweak grammar: s/make sure to/be sure to/.
18010 2002-09-02 Paul Eggert <eggert@twinsun.com>
18012 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
18013 directory names are generally preferable to physical names.
18015 2002-09-02 Akim Demaille <akim@epita.fr>
18017 * lib/Autom4te/General.pm (&update_file): s/die/error/.
18018 Reported by Raja R. Harinath.
18019 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
18020 * bin/autoupdate.in: Use error instead of die.
18022 2002-09-01 Paul Eggert <eggert@twinsun.com>
18024 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
18025 ordinary shell concatenation rather than echo+tr+sed command that
18026 runs afoul of a long-line-related sed bug in Solaris 8.
18028 * bin/autoheader.in (parse_args): --warning -> --warnings.
18030 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
18031 stdout, as traditional "ls" does.
18032 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
18033 _AC_COMPILER_EXEEXT_O): Likewise.
18034 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
18036 * bin/autoconf.as: Add --prepend-include option. This patch was
18037 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
18038 but bin/autoconf.in is generated automatically from bin/autoconf.as.
18040 * bin/autoconf.in, configure: Regenerate.
18042 * doc/autoconf.texi (Special Shell Variables): Mention
18043 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
18045 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
18046 MAILPATH and set PS1, PS2, PS4 to default values, to work
18047 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
18048 For LC_ALL etc, first try to set to "C" as POSIX requires and as
18049 the Autoconf documentation specifies; fall back to "unset" only if
18050 this fails. Use a shell for-loop for this rather than an m4 loop,
18051 to shorten the output script.
18053 2002-08-30 Paul Eggert <eggert@twinsun.com>
18055 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
18056 1003.1-2001's requirements for CDPATH. Give a simpler workaround
18057 for the CDPATH problem. Document PWD.
18058 (Limitations of Builtins): Document the problem that "cd $foo" and
18059 "ls $foo" may refer to different directories in shells conforming
18060 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
18061 example, since the old example is now out of date.
18063 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
18064 FOO" and "ls FOO" talk about different directories; this catches
18065 problems when POSIX 1003.1-2001 "cd" fails due to symlink
18068 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
18069 of rolling our own unset.
18070 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
18071 in practice we needn't worry about CDPATH if unset doesn't work.

18097 * lib/Autom4te/General.pm (&xqx): New.
18098 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
18099 hand, which is not portable.
18101 * bin/autom4te.in: Use them.
18102 Use &error instead of die.

18108 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
18109 default list of compilers to try, since it was long ago superseded

18114 * doc/autoconf.texi (Invoking autom4te): End the option table,

18136 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
18137 * Makefile.am (INSTALL): Use the new macros.

18317 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
18319 * bin/autom4te.in ($cache): Don't define using `$me', the name

18426 This improves on an earlier suggestion by H. Peter Anvin.
18428 2002-05-16 Paul Eggert <eggert@twinsun.com>
18430 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18431 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18432 Both macros now accept an optional source-dir arg.
18433 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18435 * NEWS: Document this.
18436 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18438 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18439 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18440 not for GNU extensions; this undoes part of the 2000-11-03 change,
18441 reverting to 2.13-compatible behavior.
18442 Add new optional argument DIR.
18443 (AC_FUNC_FNMATCH_GNU): New macro.
18445 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

18449 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18450 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18451 and it causes a 'test' syntax error if it fails.
18452 Bug reported by Stephen Gildea.
18454 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18455 If prototypes are supported, use them to check this at compile-time,
18456 instead of trying to check it at run-time. If we must do a run-time
18457 check, assume that setvbuf is standard when cross-compiling, as
18458 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18459 Bug reported by Paul D. Smith.
18461 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18462 argument specifying location of getloadavg.c. This removes a
18463 FIXME. This idea was taken from Jim Meyering's implementation in
18465 * doc/autoconf.texi (Particular Functions): Document this.
18466 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18467 that's what the code does; this fixes a bug reported by
18470 2002-05-03 Akim Demaille <akim@epita.fr>
18472 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18473 autopoint instead of gettextize.
18474 ($uses_alocal): Rename as...
18475 ($uses_aclocal): this.
18476 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18477 Suggested by Bruno Haible.
18479 2002-05-03 Akim Demaille <akim@epita.fr>
18481 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18483 2002-04-29 Paul Eggert <eggert@twinsun.com>
18485 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18486 files to be 1 second older; just set them to be the same time.
18487 Also, sleep 1 second after the first aclocal, to work around
18488 problems with sub-second time stamps on the input files.
18490 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18492 * doc/autoconf.texi: Mention "set -e -x" lossage
18493 under node "Limitations of Builtins".
18495 2002-04-29 Akim Demaille <akim@epita.fr>
18497 * doc/install.texi: Better wording for setting variables when
18499 From Christian Cornelssen.
18501 2002-04-29 Akim Demaille <akim@epita.fr>
18503 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18504 of lack of $LINENO support, then the test will compare the $LINENO
18505 in testsuite vs. the lineno in the test file. This is wrong, of
18507 Be sure to protect it.
18508 Reported by Patrick Welche.
18510 2002-04-25 Akim Demaille <akim@epita.fr>
18512 * doc/autoconf.texi (Obsolete Macros): Typo.
18513 Reported by Vladimir Volovich.
18515 2002-04-25 Akim Demaille <akim@epita.fr>
18517 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18518 than some of the input files, hence, on the second run of aclocal,
18519 if some of its input are younger, make them older.
18520 Suggested by Paul Eggert.
18522 2002-04-25 Akim Demaille <akim@epita.fr>
18524 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18529 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
18530 and ac_subst_vars be sh variables containing the list of
18531 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18533 (_AC_INIT_PREPARE): Use them to log them.
18534 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18535 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18536 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18537 _AC_SUBST_FILES and _AC_SUBST_VARS.
18538 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18540 2002-04-24 Akim Demaille <akim@epita.fr>
18542 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18543 autoheader, so that automake does not complain about a missing
18544 config.h.in that was to be created.
18546 2002-04-23 Akim Demaille <akim@epita.fr>

18598 Minor spelling and grammar fixes.
18600 * doc/autoconf.texi: Follow the outline suggested in the GNU
18601 Sample Texts sections of the Texinfo 4.2 manual. Most
18602 importantly, this makes sure that the copyright notices appear in
18603 all output formats. You probably need Texinfo 4.2 to generate

18642 workaround for ${1+"$@"}.
18643 * doc/autoconf.texi (Shell Substitutions): Explain it.
18644 From Oliver Kiddle and Peter Stephenson.
18646 Have M4sh perform minimal shell sanitizing.
18648 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18650 (_AS_PREPARE): this new macro.

18655 Adjust Autoconf and Autotest.
18657 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18658 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18659 * lib/autotest/general.m4 (AT_INIT): Likewise.
18660 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

18664 Use this M4sh to generate Autoconf's shell scripts.
18666 * tests/wrapsh.as: New, precursor of wrapsh.in.
18667 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18668 on Autotest and M4sh.
18669 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18670 (wrapsh.in): New target.
18671 * bin/autoconf.as: New, precursor of autoconf.in.

18702 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

18704 Use dnl, not the KILL diversion.
18706 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18707 (AC_CONFIG_LINKS): here.
18709 Don't use the KILL diversion, as it kills spurious output, which
18710 results in failures being hidden.
18711 Use m4_defn where appropriate.
18712 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18713 after the second argument.
18715 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18716 syntax, as it is provided by M4sugar.

18758 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18759 to avoid versions of HP C which don't allow that.
18761 2002-03-27 Paul Eggert <eggert@twinsun.com>
18763 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

18777 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18778 as POSIX requires, as it doesn't work with Zsh.
18779 * doc/autoconf.texi (Assignments): Document the problem.
18781 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18783 * doc/autoconf.texi (Limitations of Make): Mention more issue
18784 about VPATH, overriding of macros in sub-makes, and handling of
18787 2002-03-21 Paul Eggert <eggert@twinsun.com>
18789 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18790 problem with here-document buffer boundaries.
18792 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18793 when reinvoking the shell, to work around problems with installers
18794 who put strange things like "cd" commands in their environments.
18796 2002-03-19 Akim Demaille <akim@epita.fr>

18814 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18818 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18819 (Limitations of Usual Tools): Add mkdir section.
18821 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18822 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18823 back on AS_DIRNAME to compute prefixes otherwise; this is
18824 roughly what mkinstalldirs does. That way, we need not have
18825 our own filename disassembler. The old disassembler did not
18826 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18828 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18829 Create at_test_all by a series of assignments,
18830 not by a single assignment of a long string. The latter causes ksh
18831 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18832 presumably because of a buffer overrun.
18834 2002-03-14 Paul Eggert <eggert@twinsun.com>
18836 * lib/autotest/general.m4 (at_times_skip):
18837 Renamed from at_times. Now a boolean.
18838 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18839 says 'times: not found'.

18871 does not do it if --with-lispdir is given.

18880 subdirectory should exist.
18882 2002-03-08 Akim Demaille <akim@epita.fr>
18884 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18886 2002-03-08 Akim Demaille <akim@epita.fr>
18888 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18889 aliases the actual variables, and modifications of the former
18892 2002-03-08 Akim Demaille <akim@epita.fr>
18894 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18895 because of C-c: have m4 output in tmp files, then mv them.

18929 * doc/autoconf.texi (Transforming Names): Equality between target
18930 and host is irrelevant.
18931 (Specifying Names, Canonicalizing): Remove all references to the
18932 backward compatibility hooks. Rather, collect them all into...
18933 (Hosts and Cross-Compilation): this new section.
18934 * doc/install.texi (System Type): Ditto.
18935 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18936 that `--host' implies cross-compilation.

18940 * doc/autoconf.texi (Evaluation Macros): New.
18941 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18943 (_m4_foreach): Define the variant with immediate evaluation so
18944 that it contains exactly the items, not an expression which
18945 evaluation is the current item.
18946 (m4_re_string, m4_re_word): Don't over quote them.
18948 2002-03-04 Akim Demaille <akim@epita.fr>
18950 Instead of having stacking `shift's evaluated at the end, let
18951 `foreach' loops immediately evaluate them.
18953 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18954 $*. This is the n-th time I change my mind, but hopefully this is
18957 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18959 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18960 it was only a hack for m4_text_wrap.
18961 (m4_car2): Remove, replaced by...
18963 (_m4_foreach): Adjust.
18964 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18965 m4_bpatsubst for clarification.

19066 2002-02-05 Akim Demaille <akim@epita.fr>
19068 * lib/freeze.mk: New.
19070 2002-02-05 Akim Demaille <akim@epita.fr>
19072 Implement `autom4te --freeze'.
19074 * bin/autom4te.in (&freeze): New.
19075 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
19076 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
19078 2002-02-05 Akim Demaille <akim@epita.fr>
19080 * bin/autom4te.in (&parse_args): Implement `frozen files are
19081 optional are the sum of the previous files on the command line'.
19082 Also, pass `--reload-state=' on them, so...
19083 (handle_m4): don't.
19084 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
19085 (M4sh): Rely on M4sugar.
19086 (Autotest, M4sh, M4sugar): Use frozen files.
19088 2002-01-31 Akim Demaille <akim@epita.fr>
19090 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
19091 * doc/autoconf.texi (Initializing configure): Adjust.
19093 2002-01-30 Akim Demaille <akim@epita.fr>
19095 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
19096 alphanumeric to `-' instead of `_'.
19098 2002-01-30 Akim Demaille <akim@epita.fr>
19100 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
19101 for plain code, the other for cross-compilation code. The latter
19102 is now run with GCC only.
19103 * doc/autoconf.texi (Compilers and Preprocessors): New.
19105 2002-01-30 Akim Demaille <akim@epita.fr>
19107 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

19110 change AC_INIT default values.
19112 2002-01-29 Akim Demaille <akim@epita.fr>
19114 * tests/torture.at (Configuring subdirectories): Use configure.in,
19115 so that aclocal 1.4 works.
19116 Reported by Alexandre Duret-Lutz and Larry Schmitt.
19118 2002-01-28 Akim Demaille <akim@epita.fr>
19120 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
19123 2002-01-28 Akim Demaille <akim@epita.fr>
19125 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
19126 AUTOTEST_PATH *after* it was set.
19127 Don't put `.' in the PATH: the user should be precise and `./' if
19128 needed. In addition, given that the test suite does some `cd', if
19129 `.' is in the path, the `tested programs' sections will report
19130 programs found in the test suite's directory, while during the
19131 tests (performed in their own directory), these programs are no
19132 longer visible. In other words, the results is confusing and
19134 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

19145 2002-01-24 Akim Demaille <akim@epita.fr>
19147 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
19148 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
19149 Bourne. Use /bin/sh.
19150 From Andreas Buening.
19152 2002-01-24 Akim Demaille <akim@epita.fr>
19154 * config/config.guess, config/config.sub, config/texinfo.tex:
19155 Update from masters.

19178 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
19179 message on invalid options.
19180 * bin/autom4te.in (parse_args): Don't use
19181 Autoconf::General::getopt with non valid options.
19183 2002-01-17 Jim Meyering <meyering@lucent.com>
19185 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
19186 $ac_cv_exeext so we don't use an old, invalid, cached value.
19188 2002-01-11 Akim Demaille <akim@epita.fr>

19199 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
19200 package.m4, since is really depends upon configure.ac, not
19202 * doc/autoconf.texi (testsuite Scripts): Adjust.
19203 * tests/Makefile.am (package.m4): New.
19204 EXTRA_DIST it since its a source.
19206 2002-01-06 Akim Demaille <akim@epita.fr>
19208 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
19209 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
19210 and PACKAGE_BUGREPORT from here...
19211 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
19213 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
19214 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
19215 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
19216 * tests/tools.at (autoheader): Adjust.
19217 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
19219 2002-01-06 Akim Demaille <akim@epita.fr>

19236 * doc/autoconf.texi (New Macros): Tweak wording.
19238 2001-12-14 Akim Demaille <akim@epita.fr>
19240 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
19241 trailing files, don't apply `-rf' to files which might not be
19242 created by configure (core, core.*, and *.core), but just `rm -f'.
19243 Suggested by Jonathan Kamens.
19245 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
19247 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
19249 2001-12-14 Akim Demaille <akim@epita.fr>
19251 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
19253 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
19255 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
19256 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
19257 abs_srcdir, top_srcpath to abs_top_srcdir.
19258 (_AC_OUTPUT_FILES): Adjust.
19259 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
19260 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
19261 * tests/wrappl.in, tests/wrapsh.in: Adjust.
19263 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

19269 2001-12-12 Kevin Ryde <user42@zip.com.au>
19271 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
19272 forbidden file descriptors table.
19274 2001-11-26 Akim Demaille <akim@epita.fr>
19276 * bin/autoscan.in (%c_keywords): Build it at top level.
19277 Map to 1 in order to simplify its uses.
19279 2001-11-26 Akim Demaille <akim@epita.fr>
19281 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
19282 Remove $filepath, useless.
19283 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
19284 variables, they are really part of the tokens.
19285 Split the input line on spaces and then look for tokens.
19286 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
19287 because of `lex$U.$(OBJEXT)'.
19288 (&scan_files): Use "@list" instead of join.
19289 * doc/Makefile.am (CLEANFILES): Add *.fns.
19291 2001-11-26 Akim Demaille <akim@epita.fr>

19294 Remove, replaced by...
19295 * tests/wrappl.in: Be common for all the Perl executables.
19296 In particular autoscan and autoheader want -I.
19297 * configure.ac: Adjust.
19298 * lib/autoscan/headers: errno.h is portable.
19300 2001-11-26 Akim Demaille <akim@epita.fr>
19302 * bin/autoscan.in (used): New.
19305 2001-11-26 Akim Demaille <akim@epita.fr>
19307 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
19309 (&scan_sh_file): Remove a duplicate pattern.
19310 (&check_configure_ac): Use long options.
19311 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

19316 Before, having a line containing the opening of a multi line
19317 comment made the whole line be ignored.
19319 2001-11-26 Akim Demaille <akim@epita.fr>
19321 * doc/autoconf.texi (Using an Autotest Test Suite): New.

19327 Test groups are now run two directories deeper.
19329 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
19330 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
19332 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
19333 top_srcdir, builddir and top_builddir.
19334 Use `at_*dir' relatively to the directory containing the
19335 suite, use `*dir' when relatively to the current group dir.
19337 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
19339 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
19340 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
19341 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
19344 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
19346 * doc/autoconf.texi (Using System Type): Add an example of `case
19347 $host' usage so people quit using `case $target' everywhere.
19349 2001-11-22 Akim Demaille <akim@epita.fr>
19351 * doc/autoconf.texi (Installation Directory Variables): Englishoes
19352 spotted by Jim Meyering.
19354 2001-11-16 Paul Eggert <eggert@twinsun.com>
19356 This patch implements a `long double' suggestion by Oliver Kiddle.
19358 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
19359 static, to catch errors if the value isn't known at compile-time
19360 and the compiler supports dynamic arrays. Change its name from
19361 `_array_' to `test_array' to avoid potential name clashes.
19362 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
19363 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
19364 better than double. Catch a bug in GCC 2.95.2 x86.
19365 * doc/autoconf.texi (C Compiler): Document the above.
19368 2001-11-13 Akim Demaille <akim@epita.fr>
19370 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
19372 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
19374 2001-11-13 Akim Demaille <akim@epita.fr>
19376 * lib/autotest/general.m4 (AT_INIT): After having run the test
19377 group, go back to the initial directory, not to at_suite_dir.
19379 2001-11-13 Akim Demaille <akim@epita.fr>
19381 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
19382 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
19383 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
19385 (AT_CHECK_CONFIGURE): Use absolute paths.
19386 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
19387 The problem is still the old one: there is no means in M4 (that I
19388 know about) to create a defining macro, because there is no means
19389 to create `$1' etc., therefore, the defining macro ``swallows''
19390 all the arguments meant to the defined macro.
19392 2001-11-13 Akim Demaille <akim@epita.fr>
19394 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
19395 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
19397 * tests/aclocal.m4: Remove, as it is no longer used.
19399 2001-11-13 Akim Demaille <akim@epita.fr>
19401 * lib/autotest/general.m4: Change `tests?' into `groups?' in
19402 variable names when referring to a single test group, or to
19403 `suite' when referring to the whole test suite.
19404 `at_last_test' is removed: m4 compute at_format itself.
19405 (at_stdout, at_stder1, at_stderr): New variables.
19406 (AT_CHECK): Use them.
19408 2001-11-13 Akim Demaille <akim@epita.fr>
19410 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
19412 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19413 Do it as soon as a test fails, don't wait till the end of the test
19415 Don't remove $as_me.[0-9]*, since these files no longer exist.
19417 2001-11-13 Akim Demaille <akim@epita.fr>
19419 * tests/tools.at: Use absolute paths, since we are no longer run
19422 2001-11-13 Akim Demaille <akim@epita.fr>
19424 Now that tests are running in their own private dir, there is no
19425 need to list the files to remove at the end of tests groups.
19427 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19428 (AT_data_files, at_data_files): Remove.
19429 (AT_CLEANUP, AT_DATA): Simplify.
19431 Remove the group dir if !debug && !failed.
19432 * tests/atspecific.m4: Adjust.
19434 2001-11-13 Akim Demaille <akim@epita.fr>
19436 Start a new layout for Autotest: `testsuite' creates
19437 `testsuite.dir' in which the at-check-line etc. files are to be
19438 found, and `testsuite.dir/003' where the test group 3 is run.
19440 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19441 at_check_line_file, at_format, at_test_normalized, at_group_dir
19443 Create the directories.
19444 Use absolute paths for at- files.
19445 (AT_CHECK): Adjust.
19447 2001-11-11 Michael Matz <matz@kde.org>
19449 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19451 (m4_car): Properly quote arguments.
19453 2001-11-13 Akim Demaille <akim@epita.fr>
19455 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19456 with stricter rules on LIBOBJS.
19458 2001-11-12 Paul Eggert <eggert@twinsun.com>
19460 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19461 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19464 2001-11-12 Akim Demaille <akim@epita.fr>
19466 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19468 2001-11-12 Akim Demaille <akim@epita.fr>
19470 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19471 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19472 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19473 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19474 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19475 specify to what the macro should be defined (typically to 1).
19477 2001-11-12 Akim Demaille <akim@epita.fr>
19479 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19482 2001-11-12 Akim Demaille <akim@epita.fr>
19484 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19485 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19486 definition used by Automake where LEX is +/- "${missing} lex" and
19487 `missing' itself contains variables.
19489 2001-11-12 Akim Demaille <akim@epita.fr>
19491 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19492 Now that M4sh pushes BODY, the comments were output at the end of
19495 2001-11-08 Akim Demaille <akim@epita.fr>
19497 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19498 that we can trace macros from aclocal.m4.
19499 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19500 obsoleted, and redirect to the former anyway.
19501 Reported by Ralf Corsepius.
19503 2001-11-08 Akim Demaille <akim@epita.fr>
19505 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19506 processed only if present.
19507 * tests/torture.at (Configuring subdirectories): Use autoreconf
19508 instead of successive calls to autoconf.
19509 Add a nonexistent subdirectory to exercise the patch above.
19510 Reported by Ralf Corsepius.
19512 2001-11-08 Kevin Ryde <user42@zip.com.au>
19514 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
19515 doesn't accept .S files.
19517 2001-11-07 Akim Demaille <akim@epita.fr>
19519 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

19523 (handle_output): Use it.
19524 Read m4_pattern_forbid with messages.
19526 2001-11-05 Akim Demaille <akim@epita.fr>
19528 * bin/autom4te.in (--normalize): Remove.
19529 * lib/autom4te.in: Adjust.
19531 2001-11-05 Akim Demaille <akim@epita.fr>
19533 * tests/Makefile.am (testsuite): Rename this target as...
19534 ($(TESTSUITE)): this.
19537 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19539 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19540 the --prefix option, also remove it's argument.
19542 2001-11-05 Akim Demaille <akim@epita.fr>
19544 * doc/autoconf.texi (testsuite Invocation): Update.
19545 (Writing testsuite.at): Update.
19547 2001-11-03 Akim Demaille <akim@epita.fr>

19551 2001-11-03 Akim Demaille <akim@epita.fr>

19562 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19563 * doc/autoconf.texi (autoreconf Invocation): Update.
19565 2001-11-03 Akim Demaille <akim@epita.fr>
19567 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19568 (@export_forward_subs): New.
19569 Add basename, dirname, and fileparse.

19575 Reported by Ezra Peisach.
19577 2001-11-03 Akim Demaille <akim@epita.fr>
19579 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19580 passed on command line, defaulting to ./configure.ac if present.
19581 (&maybe_autoreconf, File::Find): Remove, unused.
19582 (&autoreconf): If autoconf is not used, don't try to trace.
19584 2001-11-02 Akim Demaille <akim@epita.fr>
19586 * configure.ac: Bump to 2.52g.
19588 2001-11-02 Akim Demaille <akim@epita.fr>
19592 2001-11-02 Akim Demaille <akim@epita.fr>
19594 * config/config.guess, config/config.sub, doc/standards.texi:
19595 * config/lispdir.m4: Update from masters.
19596 * configure.ac: Bump to 2.52f.
19598 2001-11-02 Akim Demaille <akim@epita.fr>
19600 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19601 Don't run aclocal when aclocal.m4 is not from aclocal.
19603 Don't run libtoolize and gettextize if --install is not given.
19605 2001-11-01 Paul Eggert <eggert@twinsun.com>
19607 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19608 be invoked before _AS_LINENO_PREPARE.
19609 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19610 than character ranges.
19612 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19613 invoking AS_BASENAME. Set the locale variables to 'C' if
19614 possible, as POSIX requires this to get the traditional
19616 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19618 2001-10-31 Paul Eggert <eggert@twinsun.com>
19620 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19621 with {}, as that triggers a bug in Bash 2.05.
19623 (_AS_LINENO_PREPARE): Use Sed rather than
19624 Awk. Fix the sed prepass to work even if there are multiple
19625 instances of $LINENO on the same line. Do not substitute for
19626 other variables like $LINENOT. Do not check file dates; such a
19627 check is unreliable on sufficiently fast machines, and removing
19628 the check makes the code simpler and more reliable. Check for
19629 output and chmod failures.
19631 * doc/autoconf.texi (Special Shell Variables): Document
19634 2001-10-31 Akim Demaille <akim@epita.fr>

19644 * configure.ac: Adjust.
19646 2001-10-26 Paul Eggert <eggert@twinsun.com>
19648 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19649 lib/Autom4te/Struct.pm:
19650 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19653 * doc/autoconf.texi (Special Shell Variables): Document some
19654 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19656 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19657 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19658 eval $LINENO is not portable in practice.
19660 2001-10-24 Akim Demaille <akim@epita.fr>
19662 * lib/Autom4te/General.pm (backname): New.
19664 2001-10-24 Akim Demaille <akim@epita.fr>

19674 2001-10-22 Paul Eggert <eggert@twinsun.com>
19676 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19677 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19678 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19679 POSIX decided to standardize on the int flavor of strerror_r.
19680 Always do char* test, as there's no reason not to.
19681 Assign to a char* var, to catch strerror_r that returns int*.
19683 * doc/autoconf.texi (Particular Functions):
19684 Document the above changes. Also, document the fact that
19685 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19687 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19689 2001-10-20 Akim Demaille <akim@epita.fr>

19700 (&autoreconf): Display the full path of the configure.ac we are
19702 Trace it only once.
19703 Be sure to honor --force with gettextize.
19704 Always run aclocal.
19705 * doc/autoconf.texi: Adjust.
19707 2001-10-20 Akim Demaille <akim@epita.fr>
19709 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19711 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19712 `intl' is already present, as it refuses unless --force.
19713 (&parse_args): Use -I, --include instead of the old Autoconf
19715 ($localdir, $autoconf_dir): Remove.
19717 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19719 2001-10-19 Jens Petersen <petersen@redhat.com>
19721 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19740 configure.ac being studied.
19742 2001-10-18 Paul Eggert <eggert@twinsun.com>
19744 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19745 long, to work around a bug in the HP C compiler version HP92453-01
19748 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19749 (AS_BASENAME_EXPR): New macro.
19750 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19751 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19752 and fall back on 'sed' only if the other two fail. This makes
19753 AS_BASENAME act more like AS_DIRNAME.
19754 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19755 contains white space.
19756 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19757 Use AS_DIRNAME, since I think it's now DOS-friendly.
19758 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
19759 Allow "dirname //FOO" to return either / or //, as POSIX allows

19810 bother with $force since...
19811 * lib/Autom4te/General.pm: does.
19813 2001-10-08 Akim Demaille <akim@epita.fr>
19815 * bin/autoreconf.in: Rewrite in Perl.
19816 * configure.ac: Adjust.

19900 empty, and if we can find a shell that does support LINENO,
19901 then set CONFIG_SHELL to that shell and then re-execute
19902 ourselves with CONFIG_SHELL.
19904 2001-10-05 Paul Eggert <eggert@twinsun.com>
19906 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19907 doesn't exist. Remove *.tmp, as a .tmp file is created during the

19978 Don't use nested parenthesization. This patch was originally

19987 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19988 Check for `expr' arithmetic overflow, and for compilation failure,
19989 and invoke a new argument $4 if either is discovered.
19990 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
19991 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
19993 2001-09-28 Akim Demaille <akim@epita.fr>

20220 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
20222 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
20223 Do not pass a first argument with leading '-'
20224 to expr, by parenthesizing initial integers that might be negative.
20226 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
20227 now merely checks whether it is an error to pass an argument
20230 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
20231 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
20232 whether it is a (compile-time) error to pass an argument to
20233 getpgrp. This simpler test supports the revised documentation,
20234 and is all that AC_FUNC_GETPGRP's users really need.
20236 2001-09-18 Akim Demaille <akim@epita.fr>

20250 Add test for AS_BASENAME.
20251 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
20252 added test. It now correctly handles /1/2/3/, returning '3' not ''.
20253 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
20254 * tests/base.at: Fixed the expected responses. The old ones were
20256 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
20257 the documentation claims it should (and how it behaved in 2.13).
20259 2001-09-18 Akim Demaille <akim@epita.fr>
20261 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
20262 the AC_CONFIG_COMMANDS invocation.

20265 * lib/m4sugar/Makefile.am (version.m4): Revamp.
20266 No longer to be shipped.

20270 Use `m4_PACKAGE_STRING'.
20271 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
20272 the only optional argument is the name of the test suite.
20273 Expect `package.m4' to define the package signature.
20274 * lib/autom4te.in (Autotest): Add `package.m4?'.
20275 * tests/Makefile.am (package.m4): New.

20297 the expression in an extra function before these includes. Call
20298 fprintf "%d" only after ensuring the argument is of type 'int'.
20299 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
20301 2001-09-17 Paul Eggert <eggert@twinsun.com>
20303 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
20304 or CFLAGS=-O5. In that case, the linker has a relaxed view of
20305 fatal errors, and AC_CHECK_LIB causes it to include libraries even
20306 when they don't exist.
20308 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
20309 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
20312 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
20313 version with the version used by fileutils 4.1, except use

20359 * lib/autotest/general.m4 (AT_INIT): Create and remove
20360 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

20365 * tests/mktests.sh: Don't output banners for empty test files.

20471 2001-09-05 Akim Demaille <akim@epita.fr>
20473 Be ready to handle filenames as stupid as `dnl.at', for if even
20474 the maintainer is dumb enough to do that...
20476 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20477 excellence in M4 quotation: consider `__file__' is active.
20479 And BTW, when invoking m4, pass the --include in the right order:

20505 2001-09-05 Akim Demaille <akim@epita.fr>
20507 CVS GNU M4 doesn't like `undefine(undefined)'.
20509 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
20510 New, extracted from main.
20511 Use IO::File wherever possible.
20512 (input.m4): Be constant, use -I instead of hard coding $tmp.
20513 Therefore be a quoted heredoc.
20514 Don't invoke `_au_disable', since ac was not loaded, but just

20540 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
20542 2001-08-31 Akim Demaille <akim@epita.fr>
20544 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20545 (testsuite Scripts): There is no such thing as `atconfig.in'.
20546 And actually one diagram is missing: test suite runtime.
20548 2001-08-31 Akim Demaille <akim@epita.fr>
20550 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20553 2001-08-31 Akim Demaille <akim@epita.fr>
20555 * bin/autoupdate.in (@include): `installcheck' revealed the path
20556 to m4sugar was lacking!
20558 2001-08-31 Akim Demaille <akim@epita.fr>
20560 * man/Makefile.am (.x.1): We really have to pass
20561 autom4te_perllibdir.

20571 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
20572 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
20573 Use directly autom4te, not autoconf.

20576 2001-08-31 Akim Demaille <akim@epita.fr>

20598 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
20599 (autoheader): Pass --force since the test suite goes too fast for
20601 Adjust to the new autoheader messages.

20615 Drop AC_MACRODIR dead for real.
20616 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
20617 `autoheader: `config.hin' is created'.
20618 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20620 2001-08-31 Akim Demaille <akim@epita.fr>
20622 * bin/autoheader.in: Rewrite in Perl.
20623 * tests/autoheader: Adjust.
20625 2001-08-31 Akim Demaille <akim@epita.fr>

20628 Map --localdir, --autoconf-dir onto it.
20629 Forward autom4te's options instead of interpreting them.
20630 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
20631 There is no such envvar since the inception of autom4te.cfg.
20632 * bin/autom4te.in (&parse_args): Uniquify `@include'.
20633 * bin/autoupdate.in: Adjust, and perform more control.

20635 * tests/autoconf: Dittowise.
20637 2001-08-31 Akim Demaille <akim@epita.fr>

20653 * lib/Autom4te/General.pm (&find_peer): Remove.
20654 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
20655 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
20656 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20657 find the executables for it.
20658 * tests/Makefile.am: Major cleanup. Too lazy to document...
20659 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20661 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20662 indeed related to running the test suite, while passing
20663 --autoconf-dir and others is related to running non installed
20664 Autoconf executables. So don't do that, leave it to...
20665 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
20666 * tests/autoscan: New.
20667 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20683 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
20684 Suggested by Paul Eggert.
20686 2001-08-29 Akim Demaille <akim@epita.fr>
20688 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20689 download in a tmp dir.
20691 2001-08-29 Akim Demaille <akim@epita.fr>
20693 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

20713 foo=`(command) 2>/dev/null`

20717 (AT-devnull): this.

20864 the name of the directory they're in, instead of the filename,

20953 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
20954 * NEWS, README, README-alpha, TODO, tests/README: This package is
20955 `Autoconf', not `autoconf' (the executable).
20957 2001-08-20 Akim Demaille <akim@epita.fr>
20959 Info readers seem to need `Index' in the index node title :(

21012 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

21075 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

21093 * doc/autoconf.texi: Work around Texinfo buglets.
21094 (Transformation Rules): One example is enough, users are expected
21095 to have their brains on. And BTW, use DESTDIR.
21096 (dvar): New macro. Use it.
21098 2001-08-17 Akim Demaille <akim@epita.fr>
21100 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

21153 autom4te.cache (it's a directory, not a file.
21154 * Makefile.am: Ditto (but maintainer-clean-local).
21156 2001-08-15 Akim Demaille <akim@epita.fr>
21158 * bin/autom4te.in (@m4_warning): New.
21159 (&handle_m4): Use it.
21160 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
21161 warnings are issued at each run.
21162 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
21163 is in the src tree.
21165 2001-08-15 Akim Demaille <akim@epita.fr>
21167 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
21168 don't waste time running `autoupdate --version' works.
21169 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
21171 2001-08-13 Akim Demaille <akim@epita.fr>

21230 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21232 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
21233 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
21234 * doc/autoconf.texi (C Compiler Characteristics): Update
21235 documentation for AC_C_BIGENDIAN.
21237 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

21240 magic values from an object file when cross-compiling.
21241 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
21243 2001-08-10 Akim Demaille <akim@epita.fr>
21245 * bin/autom4te.in (&handle_output): Don't use `grep' with side
21247 Suggested by Russ Allbery.
21249 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
21251 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
21252 current $prefix to the sub-configures.
21254 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
21256 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
21257 extension (needed on BeOS). Reported by Guido van Rossum.
21259 2001-08-09 Akim Demaille <akim@epita.fr>
21261 * bin/autom4te.in ($icache): Load it only if older than autom4te.
21263 2001-08-07 Akim Demaille <akim@epita.fr>
21265 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
21267 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
21268 No need to remove the files before and after the each test, before
21269 each test and at the end of the suite is enough.
21270 Display only the children `times', not the shell's.
21271 If the test failed or was skipped, at-times is not available.
21273 2001-08-07 Akim Demaille <akim@epita.fr>
21275 Always produce testsuite.log, including when there are no
21276 failures. This helps getting information on skipped tests, and
21277 duration of the tests. Err, implement the latter btw.
21279 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
21280 Dump information on the first run of each test.
21281 (AT_CLEANUP): Create `at-times' containing the duration of the
21284 2001-08-07 Akim Demaille <akim@epita.fr>
21286 The use of `dumpstat' revealed that `len' was used although it
21287 should not. m4_text_wrap was using it, but in the Autoconf world
21288 where it is legal. Hence (i) test M4sh in its own world, not
21289 Autoconf's, and (ii), ahem, fix the bug :)
21291 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
21292 does not like `' instead of [].
21293 (AT_INIT): Forbid `^_?AT_'.
21294 And don't output such tokens.
21295 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
21296 `script.as', and `autom4te.cache'.
21297 Remove `empty' and `macro' which are no longer used.
21298 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
21299 * tests/m4sugar.at: Use it.
21300 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
21302 2001-08-07 Akim Demaille <akim@epita.fr>
21304 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
21306 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
21308 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
21310 2001-08-04 Akim Demaille <akim@epita.fr>
21312 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
21313 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
21315 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
21316 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
21317 (AC_F77_MAIN): Likewise.
21319 2001-08-04 Akim Demaille <akim@epita.fr>
21321 Don't rely on M4sugar outputting the patterns in files, since we
21322 might process the output _without_ running m4, hence without these
21325 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
21326 * bin/autom4te.in (@Request::includes): Remove, unused.
21327 (@Request::source): Rename as...
21328 (@Request::input): this.
21329 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
21330 (&handle_output): Fetch the patterns from the traces.
21331 `$forbidden' and `$allowed' are constant: use m//o.
21332 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
21333 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
21335 2001-08-04 Akim Demaille <akim@epita.fr>
21337 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
21338 autoconf', i.e., in addition to caching traces, cache the output.
21340 * bin/autom4te.in (Request::cache): Rename as...
21341 (Request::id): this.
21342 ($cache, $icache, $tcache, $ocache): New.
21343 (&handle_m4): Save M4 output in the cache instead of $tmp.
21344 (&handle_output): Adjust.
21345 (&up_to_date_p): Check that the output cache is up to date too.
21346 (top level): Run `&handle_m4' iff force or the cache is invalid.
21347 Run `&handle_output' if the output cache is more recent.
21349 2001-08-04 Akim Demaille <akim@epita.fr>
21351 * bin/autom4te.in ($force): New.
21352 (&parse_args, &print_usage): -f, --force is a new option.
21353 (&handle_output): CPP directives might have spaces after `#'.
21354 (&parse_args): The first file only can be frozen.
21356 2001-08-04 Akim Demaille <akim@epita.fr>
21358 Don't let autom4te compute the `include' traces several times:
21359 first check that the trace cache file is up to date, and then
21360 compare its timestamp with that of the output.
21362 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
21363 the preamble. Don't require 5.005 as Autom4te::General does it,
21364 and better yet (use `use', not `require'!).
21365 * lib/Autom4te/Struct.pm: Rename the last occurrences of
21366 Class::Struct as Autom4te::Struct.
21367 * lib/Autom4te/General.pm (File::stat): Use it.
21368 (&mtime): New, export it.
21369 * bin/autom4te.in: Use it.
21370 Declare `$req' is invalid if it is outdated.
21371 Don't declare it valid before saving it if something went wrong.
21373 2001-08-04 Akim Demaille <akim@epita.fr>
21375 Autom4te shall not encode Autoconf data, and preselecting traces
21376 must be proposed to the users.
21378 * bin/autom4te.in (@required_trace): Remove.
21380 (&parse_args, &print_usage): -p, --preselect is a new option.
21381 (&up_to_date_p): Adjust.

21386 * tests/tools.at (autoconf --trace: user macros): Check traces on
21387 macros invoked without arguments, and macros invoked with multiple

21397 * bin/autoconf.in ($@): Work around the usual sh bug.
21400 2001-08-03 Akim Demaille <akim@epita.fr>
21402 Clean up the handling of the M4 builtins tracing exception.
21404 * bin/autom4te.in (Request::request): Don't complete M4 builtins

21407 (@m4_builtin): this.
21408 (%m4_builtin_alternate_name): New.
21409 (&parse_args): Complete the trace requests with alternate names.
21410 (&handle_traces): Hence no longer do it here.
