5993 * doc/autoconf.texi (Particular Programs): Do not mention the
5994 Autoconf version in which the AC_PROG_INSTALL change was done.
5995 Suggested by Paul Eggert.
5997 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5999 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6000 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6001 mode, we change to the source directory, also set $ac_pwd so we
6002 do not go back to the build tree for the next config subdir.
6003 * tests/torture.at (Deep Package): Extend test to contain two
6004 config subdirs on the top level.
6006 Fix parallel `maintainer-check'.
6007 * Makefile.am (maintainer-check-tests): Depend on `all'.
6008 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

6070 (m4_require): Avoid extra macro calls.
6072 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6074 * tests/torture.at (srcdir): Fix quoting.
6076 Do not pass top_srcdir to configure scripts in testsuite.
6077 * tests/autotest.at (srcdir propagation): Copy install-sh to
6079 (my only test): Drop setting of `top_srcdir'.
6080 * tests/base.at (Input/Output): Likewise.
6081 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6082 config.guess, and config.sub to test source tree.
6083 Drop AC_CONFIG_AUX_DIR setting.
6084 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6085 * tests/torture.at (Substitute a 2000-byte string): Drop
6086 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6087 (Substitute a newline, datarootdir workaround): Likewise.
6088 (Define a newline): Adjust for linenumber changes in configure.ac.

6096 * tests/tools.at (Syntax of the shell scripts): Likewise.
6098 * tests/m4sh.at (LINENO): Quote $0.
6100 Fix testsuite program wrapper for whitespace in `pwd`.
6101 The problem here is that the usual mantra is that command
6102 variables can contain arguments, thus we cannot just escape
6103 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6104 $top_builddir/tests directory early in $PATH, so that the
6105 wrappers are found by their plain name.
6106 * tests/wrapper.as: Put $testdir early in $PATH.
6107 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6109 Proper config.status --file/--header and $srcdir escaping.

6120 Quote $at_group_dir.
6121 * tests/autotest.at (whitespace in absolute testdir): New test.
6123 * lib/autom4te.in: Quote @datadir@.
6125 Proper file name escaping in Autoconf programs and Perl modules.
6126 This includes escaping of characters special to the shell
6127 as well as special to Perl, e.g., leading `<' or `>'.
6128 For example, when $file starts with `>', `open ">$file"'
6129 wrongly tries to append to a different file.
6130 * bin/autoconf.as: Fix quoting for autom4te options.
6131 * lib/Autom4te/General.pm (shell_quote): New function, taken
6132 from coreutils, written by Jim Meyering.

6141 * tests/tools.at (autom4te and whitespace in file names): Extend
6142 test. Test twice, with special characters allowed on w32, and the
6143 rest. Test leading and trailing whitespace, for `open_quote'.
6144 (autotools and whitespace in file names): New, analogous test.
6145 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6146 by Russ Allbery and Eric Blake.

6150 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6151 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6152 (update_file, contents): Use it.

6176 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6177 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6178 #undef as this runs afoul of our new way of creating config.h.
6179 Problem reported by Jim Meyering in
6180 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

6198 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6200 * lib/autotest/general.m4 (AT_INIT): For awk line number

6202 even for the empty set, and properly quote its usage inside
6205 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6207 * doc/autoconf.texi (Shell Functions): New chapter. Document
6208 IRIX sh $0 issue in functions, move content from ...

6211 totally unportable any more.

6227 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6228 Do not use $0 inside a function, as IRIX sh will set that to the
6229 function name rather than the script invocation name.
6231 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6232 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6236 (AT_INIT): Extract and cache test script line numbers.
6238 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6240 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6241 subsequent fixups; the awk -> here-document conversion trashes
6242 performance too much with AIX sh.
6244 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6246 * tests/local.at: Do not test m4, perl with AT_TESTED.
6248 Diagnose and guard against write errors dealing with config.status.
6249 The general idea is this: all write failures from `configure'
6250 writing `config.status' are indicated by $ac_write_error, which
6251 is only checked at the end. This is safe because config.status
6252 code is not executed before the file is complete. Other write
6253 failures, be they inside config.status, or in sub shell/awk
6254 scripts spawned from configure or config.status, typically need
6255 earlier checking, as their results are used right afterwards.
6256 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6257 before writing config.status, check afterwards.
6258 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6259 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6260 Set `ac_write_error' for write failures to config.status. Barf
6261 upon write failures to temporary files.
6262 Adjust note about closing and reopening the here-document.
6263 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6264 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6265 reopening the here-document.
6266 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6267 Ensure `ac_write_error' does not escape into config.status.
6268 Also, add a couple of code paths not yet exercised in the test
6269 suite: a config file with input from stdin, and a config header
6271 Suggestion for catching write errors by Bruno Haible.
6273 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6275 Avoid error with Tru64 awk and testsuite lines with many words.
6276 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6277 reads the testsuite, set the field separator to an unusual value,
6278 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6279 even splits the input if $i, i>0, was never accessed in the script.
6281 Revert 2007-10-17 change.
6282 * TODO: Multiline args in config files and headers mean something
6283 different and are not fixed, see

6301 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

6343 2007-11-13 Jim Meyering <meyering@redhat.com>
6345 Clean up the rule to create "expr".
6346 * tests/Makefile.am (expr): Don't redirect directly to target.

6355 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6356 These no longer check for preprocessor flaws.
6357 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6358 Do not check for preprocessor flaws.
6360 2007-11-13 Jim Meyering <meyering@redhat.com>
6362 Adapt dependencies, now that a version change doesn't modify configure.ac

6383 2007-11-12 Jim Meyering <meyering@redhat.com>
6385 Add more non-srcdir build support.
6386 * GNUmakefile (dummy): Split a long line.
6387 Add -v option to autoreconf invocation.
6389 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6390 * GNUmakefile (dummy): Remove INSTALL.
6392 Remove racy commands to build scripts in bin/ and tests/.
6393 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6394 are guaranteed to be built, remove the rules that tried to build
6395 them. Before, with a parallel build, these rules could lead to
6396 two processes writing tests/wrapper.in concurrently.
6398 Build in man/ only *after* building in bin/ and tests/.
6399 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6400 in both bin/ and tests/.
6402 Accommodate non-srcdir build-from-checkout.
6403 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6404 Use git's --git-dir=$srcdir/.git option.
6405 Add quotes, in case tarball_version_file contains shell meta-characters.
6406 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6407 * configure.ac: Pass "." to git-version-gen.
6409 Avoid spurious test failures due to version skew.
6410 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

6439 Ignore configure --help* errors due to LINENO-impaired shells.
6440 * tests/torture.at (Configuring subdirectories, Deep Package):
6441 In the --help* tests in read-only trees, make `.' temporarily
6442 writable again for the `stderr' file, and ignore errors due to
6443 the attempt to write configure.lineno.
6444 Report by Patrick Welche.
6446 2007-11-10 Jim Meyering <meyering@redhat.com>
6448 Generate package.m4 in build-dir, not srcdir.
6449 * tests/Makefile.am (package.m4): Adjust target.
6450 Don't redirect directly to $@.
6451 (CLEANFILES): Add package.m4.
6452 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6454 When running $(AUTOTEST), search "." before searching $(srcdir).
6456 Avoid a race condition that would make parallel "distclean" fail.
6457 * tests/Makefile.am (distclean-generic): Replace the default,
6458 automake-provided rule with an identical one, but with an additional
6459 dependency on distclean-local. Simply adding the dependency would
6460 cause automake not to emit the rule at all.
6461 * BUGS: Building with -jN works, now.
6463 Distribute git-version-gen.
6464 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6465 since GNUmakefile is distributed, and requires it for dist* rules.
6467 Remove two more generated files from version control.
6468 * INSTALL: Remove generated file.

6493 Adjust the documentation of autotest WRT atlocal.

6495 when using Automake, to write a rule to produce atlocal, since it's
6496 an AC_CONFIG_FILES. Mention that atlocal.in needs to be

6596 2007-10-28 Jim Meyering <meyering@redhat.com>
6598 Make inter-release --version output more useful.
6600 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6601 which indicates that it is built using the 19th change set
6602 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6603 is a prefix of the commit SHA1.
6604 * build-aux/git-version-gen: New file.
6605 * configure.ac: Run it to set the version.
6606 (AM_INIT_AUTOMAKE): Don't check NEWS here.

6609 * .gitignore: Add .version here, too. Just in case.
6610 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6611 not configure.ac, now that the version number changes automatically.
6613 Ensure that $(VERSION) is up to date for dist-related targets.
6614 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6615 git-version-gen doesn't match $(VERSION), but only for dist targets.

6686 this resolution. Fixes test failure on FreeBSD.
6688 Fix config header generation with AIX awk.
6689 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6690 script, use helper array D_is_set, as `" 0"' does not evaluate

7912 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7913 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7914 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7915 works but the latter doesn't, then it's a valid type.
7916 This lets people use function types and so forth.
7917 For C++ there doesn't seem to be a simple solution, so leave it alone.
7918 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7919 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

7981 2007-03-09 Stepan Kasal <kasal@ucw.cz>
7983 * doc/autoconf.texi (Specifying Names): `--host' does not
7984 change the build type.
7986 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

8008 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
8009 Reindent for sanity's sake.
8011 2007-02-24 Eric Blake <ebb9@byu.net>
8013 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

8022 status of rm so we know when it failed.
8023 If cleaning of test dir failed before running the test, warn.
8024 Output the line separator in verbose mode before the warning
8025 to make clear the warning belongs to the following test.

8052 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
8053 input from /dev/null in awk test, so even Solaris /usr/bin/awk

8090 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8091 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8092 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8093 substitution will still be done by the special code.

8109 Report against Automake by Patrick Welche.
8111 2007-01-15 Stepan Kasal <kasal@ucw.cz>
8113 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
8115 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8117 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8118 early on the reader side, drop stderr of the input to avoid
8119 `broken pipe' error output; this may happen even with shell
8120 builtin `echo' of some bash versions. Reports by Ian Macdonald
8121 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8123 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8125 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

8135 Fix some wording problems noted by Paolo Bonzini in:
8136 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8137 * doc/autoconf.texi (Signed Overflow Examples): Give more
8138 discussion about the allow_superuser_privileges example,
8139 and change it a bit to make things clearer.
8140 (Optimization and Wraparound): Clarify whether the compiler
8141 will generate an infinite loop for the example derived from
8142 Autoconf's mktime test.
8143 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8144 Also, clarify unsigned multiplication overflow.
8146 2007-01-04 Eric Blake <ebb9@byu.net>
8148 * bin/Makefile.am (RELEASE_YEAR): New macro.
8149 (edit): Use it to supply correct copyright year to scripts.
8150 * bin/autoconf.as (version): Use it.
8151 * bin/autoheader.in ($version): Likewise.
8152 * bin/autom4te.in ($version): Likewise.
8153 * bin/autoreconf.in ($version): Likewise.
8154 * bin/autoscan.in ($version): Likewise.
8155 * bin/autoupdate.in ($version): Likewise.
8156 * bin/ifnames.in ($version): Likewise.
8158 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8160 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8161 feedback. The most important changes document what happens when
8162 you convert an out-of-range value to a signed integer type, and
8163 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8166 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8167 rewrite, taking notions from the recent discussion on the gcc and
8168 autoconf mailing lists; please see
8169 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8170 and follow the many links.
8171 (Integer Overflow Basics, Signed Overflow Examples):
8172 (Optimization and Wraparound, Signed Overflow Advice):
8173 (Signed Integer Division): New sections.
8175 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8177 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8178 preprocessor macro arguments in traced name.
8179 * doc/autoconf.texi (Defining symbols): Document longstanding
8180 support for AC_DEFINE-ing macros with arguments, and document
8181 behavior when the same variable has multiple AC_DEFINEs.
8182 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8183 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8184 macros directly, giving much shorter and simpler code.
8186 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8188 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8189 space before "$ac_configure_args" to prevent a 'config.status
8190 --recheck' failure if ac_configure_args doesn't contain a leading
8191 space. This works around a problem with the XEmacs configure.ac,
8192 which uses the (undocumented) ac_configure_args variable
8193 inconsistently with Autoconf.
8195 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8197 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8198 Include <limits.h>, and use its INT_MAX to rewrite the
8199 j loop so that it does not overflow 'int'. Problem reported by
8201 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8202 Play it safe by shifting left by 1 rather than multiplying by 2,
8203 as GCC is less likely to optimize this away when the value
8204 is signed (when it assumes overflow leads to undefined behavior).
8205 Also, don't assume time_t uses two's complement.
8207 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8209 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8210 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8211 dumps core on it. Report by Tim Rice.
8213 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8215 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8216 --disable-option-checking to --help output even when
8217 AC_PRESERVE_HELP_ORDER is not used.
8218 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8219 --with argument, rather than argument with [-.] replaced by
8221 * NEWS: Fix typo in previous change; the news was in the
8224 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8226 * NEWS: Warnings are now generated by default for unknown
8227 --enable-* and --with-* options.
8228 * doc/autoconf.texi (Option Checking): Renamed from
8229 (Configure Option Checking). Tighten up the wording a bit.
8230 (External Software, Package Options): Cross-reference to Option
8231 Checking, and use this to shorten our section.
8232 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8233 "$x" to test "x$foo" != x.
8234 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8235 Don't warn if $enable_option_checking is "no".
8236 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8237 ac_unrecognized_opts to the empty string.
8238 Don't echo the unrecognized opts, as this might mishandle
8239 backslashes or leading -.
8240 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8241 usage next to the other --disable-FEATURE options in the
8244 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8246 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8247 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8248 Print warning for unrecognized --with and --enable options
8249 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8250 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8251 Disable option checking when subdirs are configured.
8252 (AC_OUTPUT): If warnings are enabled, print warning about
8253 unrecognized --with and --enable options at the end of
8254 the configure output (as well as at the beginning).
8255 * doc/autoconf.texi (Option Checking): New node.
8256 Document new option warning functionality.
8258 2006-12-16 Eric Blake <ebb9@byu.net>
8260 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8261 * NEWS: Start news for current version.
8263 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8265 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8266 Define HAVE_GETMNTENT to 1, not to the empty string.
8267 Problem originally reported by Jochen Friedrich in
8268 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8270 This change prompted by a problem report by Andrey Simonenko in
8271 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8272 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8273 object-like macros only, in the traditional portable character
8275 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8276 Warn about attempts to define things that are not identifiers.
8277 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8278 awful hack that AC_DEFINEd macro names containing parentheses.
8280 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8282 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8283 too drastic, even if Texinfo in theory requires it for info mode.
8285 (config.status Invocation): Renamed back from Recreating a
8287 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8288 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8290 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8292 * NEWS: Version 2.61a.
8294 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8295 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8297 * NEWS: Document changes with echo and printf, and the lack
8298 of limits on the total size of multi-line values of substituted
8299 variables, and the AC_FUNC_FSEEKO fix.
8301 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8303 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8304 Writing configure.ac.
8305 (Autoconf Input Layout): Renamed from configure.ac Layout.
8306 (Recreating a Configuration): Renamed from config.status Invocation.
8307 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8308 (acconfig Header): Renamed from acconfig.h.
8309 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8310 (Writing Testsuites): Renamed from Writing testsuite.at.
8311 (Autom4te Cache): Renamed from autom4te.cache.
8313 * BUGS: Remove mention of VPATH problem, since it's now documented
8314 not to be a bug in the Autoconf build procedure itself, but rather
8315 a problem with the proprietary `make' programs.
8317 * doc/autoconf.texi (Build Directories): Add a cross reference
8320 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8321 * doc/standards.texi: Sync from gnulib.
8323 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8324 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8325 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8326 generated automatically.
8328 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8330 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8331 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8332 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8334 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8336 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8337 `CEOF$ac_eof' special marker, the awk script cannot contain a
8338 line matching `^CEOF', so this is not needed any more.
8339 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8340 special marker in the test.
8342 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8344 * tests/tools.at (autom4te preselections): Use `find -newer';
8345 remove one of the sleeps.
8347 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8348 more readable, using ...
8349 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8351 * doc/autoconf.texi (autoheader Invocation): Do not double-
8352 quote the parameter of `AH_BOTTOM' in the example.
8354 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8356 * doc/autoconf.texi (Configuration Headers): Remove the
8357 example with multiple input files.
8358 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8359 multiple input files.
8361 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8363 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8364 creating the awk substitution script, handle one input line at a
8365 time, so that the maximum length of a substituted (multi-line)
8366 value is not limited by the size of the sed pattern space.
8367 The trade-off is a slightly repetitive sed script.
8368 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8369 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8370 * tests/torture.at (Substitute a 2000-byte string): Increase the
8371 test with several long lines, they should not be caught by sed
8374 * tests/tools.at (autom4te preselections): New test, to flag
8375 entries missing from autom4te.cfg.
8376 Report by David Byron <dbyron@hheld.com>.
8378 * tests/torture.at (Substitute a 2000-byte string): Actually use
8379 AC_PROG_AWK, so the last change works as intended.
8380 (Substitute and define special characters): Likewise.
8381 (Substitute a newline): Likewise.
8383 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8384 instead of `awk' consistently.
8385 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8386 * tests/torture.at (Torturing config.status): Test both the
8387 result of AC_PROG_AWK and plain awk.
8388 (Substitute a 2000-byte string): Likewise.
8389 (Substitute and define special characters): Likewise.
8390 (Substitute a newline): Likewise.
8392 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8394 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8395 can be assigned to a function pointer. Problem reported by
8396 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8397 part of a patch by Ralf Wildenhues in that same bug report.
8399 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8401 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8402 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8404 2006-12-01 Eric Blake <ebb9@byu.net>
8406 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8407 cross-compiling from cygwin to mingw.
8408 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8409 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8410 to lib/autoconf/c.m4.
8412 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8414 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8415 string for more reliable failure. Wrap the entire test that
8416 causes the broken Solaris printf to dump core, in a subshell,
8417 so the segmentation fault message is reliably suppressed.
8418 Fix shell expansion errors by using /usr/ucb/echo always;
8419 avoid an error on systems without it by another subshell.
8420 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8421 subshell-$as_echo to `as_echo', for better error message.
8423 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8431 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8432 years and is too hard to maintain now. The last straw was
8433 reported by Jerker Baeck in
8434 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8435 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8436 * doc/autoconf.texi (Particular Functions): Move
8437 AC_FUNC_SETVBUF_REVERSED from here...
8438 (Obsolete Macros): ... to here. Say that it does nothing now.
8439 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8440 Turn into (almost) a no-op.
8442 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8444 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8445 These macros are obsolescent and new applications shouldn't need them.

8453 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8455 * doc/autoconf.texi (Setting Output Variables): Mention that
8456 @VAR1@VAR2 has unspecified behavior. Problem reported by
8458 * NEWS: Mention this.
8460 * Makefile.am: Put only a single '#' into the copyright notice,
8461 so that it's also present in the output file. Standardize wording
8462 in makefile copyright notices to match GNU coding standards.

8478 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8479 in the sed script that mangles the awk script: delete up to the
8480 first exclamation mark only.
8481 * tests/torture.at (Substitute and define special characters):
8484 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8486 Rewrite config files generation: avoid quadratic growth in
8487 the number of substituted variables by using awk instead of sed
8488 for the bulk of the substitutions.
8489 * NEWS: Mention this.
8490 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8491 forbidden in the output (and thus input) file.
8492 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8493 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8494 generate just one large awk script for substitutions,
8495 eliminating much of the earlier complexity, while adding some
8496 new complexity. Only expand the substitution templates at
8497 configure time, for smaller configure script size. If
8498 _AC_SUBST_FILES are used, test 'awk' for working getline support
8499 at config.status time. If absent, interpolate through the
8500 shell. The awk script was written with much help
8501 from Paolo Bonzini and Paul Eggert.
8502 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8503 (_AC_SED_FRAG_NUM): Likewise.

8507 * tests/torture.at (Substitute a 2000-byte string): Also
8508 substitute a line with 1000 words, and a variable with several
8510 (Substitute and define special characters): Test awk special
8511 characters, and put substitution input strings `@foo@' in the
8512 output, to test that no recursion happens; test several other
8513 combinations from Paolo Bonzini.
8515 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8517 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8518 that replaced echo with AS_ECHO where this wasn't necessary.
8519 Problem reportd by Ralf Wildenhues.
8520 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8521 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8522 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8524 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8526 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8528 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8530 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8531 that traditional Awk lacks 3-arg "split". It has it.
8532 Mention that FS must be a single character, and a few other
8533 99-byte limits of traditional Awk.
8534 Mention that if (i in a) doesn't work with traditional Awk.

8540 (Newline-CODE-BS-newline in command):
8541 (Single-quote-BS-newline in command):
8542 (Single-quote-newline-BS-newline in command):
8543 Use printf '%s\n' instead of echo, for portability to hosts
8544 where echo interprets backslashes. This will break on hosts
8545 that lack printf, but for now let's assume all such hosts
8546 are dead (if not, we should get reports of test failures).
8548 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8550 'echo' has some portability problems, when given a first argument
8551 with a leading '-', or when given any argument containing '\'.
8552 Avoid using 'echo' in these cases.

8581 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8582 Don't use ECHO_T, since ECHO_N is now reliable.
8583 * lib/autotest/general.m4 (AT_INIT): Likewise.
8584 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8585 rather than using a here-document to put the script into a file.
8586 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8588 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8590 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8591 bug, but we might as well stop using ECHO_N and ECHO_C internally.

8594 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

8596 operand, as AS_ECHO requires. Avoid double file name expansion.
8597 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8598 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8599 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8600 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8601 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8602 Double-quote strings that would otherwise contain M4 comments.
8603 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8605 * configure.ac (AC_INIT): Bump to 2.61a.
8608 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8612 * configure.ac (AC_INIT): Bump to 2.61.
8615 * tests/autotest.at (Macro with backslash in a test title):
8616 Comment out for now, as this tests neither fails nor passes
8617 reliably. Problem reported by Ralf Wildenhues.
8619 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8621 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

8732 and Stepan Kasal <kasal@ucw.cz>
8734 Handle special characters in test case titles correctly.
8735 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8737 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8738 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8739 argument. Extend to check titles printed by ./micro-suite and
8740 ./micro-suite -l and the title in micro-suite.log.
8741 (Backquote in a test title,
8742 Single-quote in a test title,
8743 Double-quote in a test title): Don't expect failure anymore.
8744 (Backslash in a test title): Put a non-whitespace character after the
8745 backslash so that Bourne shells might actually see it as an escape
8747 (Brackets in a test title,
8748 Pound in a test title,
8749 Comma in a test title,

8767 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8768 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8769 5363) simply issues a warning when dividing by zero at compile
8770 time. Problem reported by Elias Pipping.
8772 2006-10-26 Eric Blake <ebb9@byu.net>
8775 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8776 show effect on macros that expand with commas.

8804 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8805 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8806 reported by Nelson H. F. Beebe for Coreutils 6.4.
8808 * tests/tools.at (autoconf --trace: user macros): Remove test
8809 for tracing multiline macros, since m4 1.4.7a uses a different
8810 way to number lines. Problem reported by Ralf Wildenhues.

8886 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8888 (Imported from Automake.)
8889 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8890 which incorrectly sets the mode of an existing destination
8891 directory. In some cases the unpatched install-sh could do the
8892 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8893 system. We hope this is rare in practice, but it's clearly worth
8894 fixing. Problem reported by Alex Unleashed in
8895 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8896 Also, don't bother to check for -m bugs unless we're using -m;
8897 suggested by Stepan Kasal.

8971 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8973 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8974 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8975 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8976 Use a better substitute, by inspecting the output of "ls"
8977 rather than just using ":".
8978 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8979 rather than AS_EXECUTABLE_P, since we needn't worry about
8980 non-regular files here.
8982 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8983 due to configuration hassles with this. See Tonya Underwood's report
8984 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

8995 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
8996 initialization which is not inherited through the environment

9005 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9007 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9008 comment about ac_cpp_err; it was incorrect, and anyway
9009 ac_cpp_err is being removed below.
9010 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9011 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9012 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9014 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9015 with werror_flag and conftest.err and so forth. This is more
9016 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9017 and anyway the user shouldn't normally want to see this gorp logged.
9018 Problem reported by Ralf Wildenhues.
9019 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9020 empty, not 'no', since the rest of the code uses 'test -z'.
9022 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9024 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9025 Use a single call to AC_DO_TOKENS rather than multiple, for
9027 (_AC_LINK_IFELSE): Test that resulting file is executable.
9028 Problem reported by mwoehlke in
9029 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9031 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9032 than creating a file to use with test -x; this is much faster.
9034 2006-10-02 Bruno Haible <bruno@clisp.org>
9036 * lib/autom4te.in (Automake-preselections): Add
9037 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

9046 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9047 fseeko testing program twice; just use the earlier result.
9048 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9049 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9050 still doesn't let the program compile.
9051 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9054 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9055 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9056 include it, without including anything else.
9057 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9059 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9064 `error.h', and include it, for a `error_at_line' prototype.
9065 Use a nonempty format string in the link test.
9066 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9067 for a declaration of wait3.

9073 can apply to constants too, and that it checks for macro defns.
9074 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9076 values. Problem reported by Ralf Wildenhues.

9291 broken lex libraries like native ia64-hp-hpux11.22; see
9292 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

9420 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
9421 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9422 -Wundef -Werror". Problem reported by David Fang in

9483 less skeptical about "volatile", after discussion with
9484 Bruno Haible on bug-gnulib.
9485 (Limitations of Usual Tools): Warn about sed stripping
9486 leading white space from text. From Bruno Haible.
9488 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
9490 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
9491 compiler complains about it, even if things works after the
9492 complaint. Problem reported by Peter O'Gorman.

9500 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

9513 under AC_C_VOLATILE.
9514 (Volatile Objects): Be a little less skeptical about what
9515 "volatile" means. Derived from thoughts by Ben Pfaff in
9516 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

9522 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9524 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9525 more globally, since the 2006-06-30 patch didn't suffice. Problem
9526 reported by Keith Marshall. Also, don't bother with builddir2,
9527 since it shouldn't be needed any more.
9529 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9548 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9550 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9551 Require that long long int be at least 64 bits wide. C99 requires
9552 this and enough programs depend on it so we should check for it.
9553 Bruno Haible reports in
9554 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9555 that long long int is 32 bits wide with some nonstandard compilers.
9556 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
9558 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
9560 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9561 to a nonexistent file, so that we don't have to worry about
9562 a local site configuration that doesn't use /usr/local.
9563 Problem reported by Keith Marshall in
9564 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9566 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9568 * doc/autoconf.texi: Be more consistent about using @acronym with
9569 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9570 quite right (it talked about "OSF/Tru64", even though the
9571 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9572 and it even mentioned "OSF 4"!) and at this point there's little
9573 reason to talk about OSF any more, since it died in 1994.
9574 (Specific Compiler Characteristics): Simplify example of
9575 negative-size array.
9576 (File Descriptors): Reorder to make the text flow better.
9577 Remove joke about "appreciate the various levels"; I didn't get it.
9578 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
9579 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9580 (File Descriptors, Limitations of Usual Tools):
9581 Tone down the advice against renaming or removing open files.
9582 (Limitations of Usual Tools): Add a new section, on 'rm'.
9584 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9586 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9587 -lXt in LIBS, idea from Karsten Hopp; this was due since
9590 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9591 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9592 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9593 (which belong to Xt, not X itself). See Debian bug 327655.
9595 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9597 * configure.ac (AC_INIT): Bump to 2.60a.

9617 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9619 * doc/autoconf.texi (Changed Directory Variables): New node,
9620 to document the whole `datarootdir' business a bit better.
9622 * tests/torture.at (datarootdir workaround): Extend test.
9623 Prompted by report by Alexandre Julliard.
9625 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9627 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9628 when using default mode of IBM C 6 for AIX. Problem and two-line
9629 fix reported by Larry Jones.
9631 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9633 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9634 about literal '${datarootdir}' if a definition is found in the
9637 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9639 * NEWS: Use "M4" rather than "m4" when appropriate.
9640 Problem reported by Eric Blake.
9641 * doc/autoconf.texi: Likewise.
9642 Use @acronym around BSD, GCC, and GNU when appropriate.
9643 (Why GNU M4): Renamed from "Why GNU m4".
9644 (Redefined M4 Macros): Mention that Posix
9645 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9646 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9649 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9651 * bin/autom4te.in (handle_output): Do not forbid the empty
9653 * tests/tools.at (autoconf: the empty token): New test.
9655 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9657 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9658 calls, so that we do not care whether they are LIFO or FIFO;
9659 in the m4_wrap, do not check which diversion is the topmost
9660 one, just check that the stack is balanced at the end.
9661 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9662 base diversion forever--pop the previous diversion before
9663 opening the new one; consequently, remove the m4_wrap call.
9664 * lib/autotest/general.m4 (AT_INIT): Likewise.
9665 * tests/m4sugar.at: Do not use
9666 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
9668 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9669 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9671 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9672 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9673 Rework example of m4wrap token-pasting trouble so that it doesn't
9674 care whether it's LIFO or FIFO.
9675 Fix some "contrary to"s that are awkward in English.
9677 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9679 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9680 to `yes' instead of `int$1_t' if the type is found, for more
9681 consistent configure output (where $1 is the number of bits).
9682 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9683 Suggested by Bruno Haible.
9685 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9686 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9687 with system headers. Report by Bruno Haible.
9689 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9691 * config/config.guess, config/config.sub: Sync from upstream.
9693 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9694 in order to avoid picking up an older installed frozen m4sh.m4f.
9695 Besides an outdated shell startup, this could have been created
9696 by an earlier M4 version with incompatible frozen file format.
9698 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9700 * README: Recommend m4 1.4.4 instead of 1.4.3..
9701 * doc/autoconf.texi: Likewise.
9702 (Special Chars in Names): Say that $(.FOO) is portable, as
9703 suggested by Stepan Kasal.
9704 (Installation Directory Variables, Build Directories):
9705 (Automatic Remaking, Subdirectories, Fortran Compiler):
9706 (Making testsuite Scripts, Defining Directories):
9707 Quote variable usages better.
9708 (Making testsuite Scripts): Add clean-local rule to makefile
9709 snippet, by Eric Blake.
9710 (Installation Directory Variables): Fix table item font.
9711 Reword slightly to clarify. Generalize advice about
9712 not using special characters to include all file-related
9713 vars, not just VPATH.
9714 (Special Chars in Variables): Warn about special characters in
9716 (Assignments): Clarify default-value example as suggested by
9718 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9719 (Special Shell Variables): Note leading ./ or ../, as suggested
9721 (Limitations of Builtins): Under cd, warn about CDPATH.
9722 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9725 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9727 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9728 `@var', for texi2html.
9729 (Systemology): Some more word wrapping, for DVI output.
9730 (autom4te Invocation): The short option for `--melt' is `-M',
9733 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9735 * doc/autoconf.texi: More formatting and English tweaks,
9736 many suggested by Ralf Wildenhues.
9737 Reword to avoid "@code{...}'s" and the like, since it's ugly
9738 with Emacs info mode. discontents -> woes.
9739 Put a few "will"s back. time stamp -> timestamp.
9740 side-effect -> side effect.
9742 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9744 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9745 Warn about $@ not persisting. Problem reported by Julien Danjou in
9746 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9747 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9748 Mention other special chars, too.
9750 2006-06-14 Eric Blake <ebb9@byu.net>
9752 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9754 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9756 * doc/autoconf.texi: Some systematic minor improvements, as
9757 follows. Use "makefile" when talking about makefiles
9758 generally (which might be named "makefile" or "Makefile" or even
9759 "foo.mk"), "Makefile" when talking about a specific makefile
9760 called "Makefile". This unclutters the text from weird quotes
9761 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9762 values" rather than "@var{foo}s" and similar constructs containing
9763 "}s". Use "Make rules" rather than "Makefile rules". Minor
9764 English-language improvements. Change the prefix "sub-" to "sub"
9766 Put blank lines around examples more consistently.
9767 Avoid "rather" and "very" as intensifiers.
9768 Avoid "will" as an auxiliary.
9769 (Limitations of Make): Split this node into....
9770 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9771 (Leading _ in Macro Names, Backslash-Newline-Newline):
9772 (Backslash-Newline Comments, Long Lines in Makefiles):
9773 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9774 (obj/ and Make, make -k Status, VPATH and Make):
9775 (VPATH and Double-colon, $< in Explicit Rules):
9776 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9777 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9778 New nodes, resulting from splitup of Limitations of Make.
9779 All cross-references changed. Raise the top node from
9780 a section to a chapter, and all subnodes accordingly.
9781 Redo the introductory wording to match the new organization.
9782 (Installation Directory Variables): Use an example that is
9783 closer to what Autoconf actually does. Mention that VPATH's
9784 value should not contain metacharacters or white space.
9785 (Fortran Compiler): Fix a VPATH bug in an example.
9786 (Leading _ in Macro Names): Mention that this problem is no longer
9787 of practical concern.
9788 (VPATH and Make): Reword the advice to make it clearer
9789 that Autoconf and Automake support VPATH in non-GNU make, but
9790 many packages have bugs in this area.
9791 ($< in Explicit Rules): Refer to Build Directories rather
9792 than using a (non-VPATH-safe) example.
9793 (Automatic Rule Rewriting): Mention the sort of disaster that
9794 can ensue with Solaris-style rule rewriting with VPATH.
9796 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9798 * doc/install.texi (Compilers and Options): Weaken the
9799 suggestion to use GNU make for VPATH builds.
9801 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9802 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.

9805 in regular expression.
9807 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9809 * doc/autoconf.texi (Installation Directory Variables):
9810 Drop extra @samp from `@table @samp' item.
9811 (Limitations of Usual Tools): Comment fix.
9812 Do not nest @samp just to point to other table items.
9813 (Writing testsuite.at) <AT_CHECK>: The second argument to
9814 `@dvar' is already @samp'ed.
9815 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9816 do not use @var in the second argument.
9818 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9820 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9821 $as_shell.exe too. Problem reported by Andreas Buening in
9822 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9824 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9826 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9827 `unused variable' compiler warning, for `-Wall -Werror'.
9828 Reported by Jaap Haitsma in
9829 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9831 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9833 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9834 case the compiler dumps core. Problem reported for
9835 OpenServer 5.0.7 by Tim Rice in
9836 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

9840 2006-06-06 Tim Rice <tim@multitalents.net>.
9842 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9843 "ERROR" only shows up in "make check" output if there is an
9846 2006-06-06 Eric Blake <ebb9@byu.net>
9848 * tests/tools.at (automatically allowed tokens): Fix typo.

9867 * config/texinfo.tex: Sync from upstream.
9869 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9870 seen, invoke libtoolize with `--ltdl' argument.
9871 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9873 Suggested by Eric Blake.
9875 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9877 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
9878 reported by Ralf Wildenhues.

9891 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9892 message issued by AC_REQUIRE.
9893 * tests/m4sugar.at: Check m4_require's error message.
9894 * tests/base.at: Check AC_REQUIRE's error message.
9895 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9897 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9899 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9900 `expout' as the last parameter.
9901 * tests/tools.at: Adapt to the above change.
9903 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9905 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9906 information about race-free implementations of mkdir.
9908 2006-06-04 Eric Blake <ebb9@byu.net>

9913 * doc/autoconf.texi (autom4te Invocation): Likewise.
9915 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9917 * NEWS: GNU make now recommended for VPATH builds.
9918 Mention that some macros are now documented to be obsolescent.
9919 * doc/autoconf.texi:
9920 Prefer "current" to "modern" to describe
9921 currently-used (albeit perhaps old-fashioned) hosts.
9922 Mention which ancient features no longer need to be worried about.
9923 setgid -> set-group-ID
9924 setuid -> set-user-ID (these are the Posix terms)
9925 Fix some misuses of "only".
9926 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9927 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9928 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

9935 Mention that these macros are obsolescent.
9936 (Installation Directory Variables): shall -> should
9937 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9938 Mention that it's now safe to use 3 and 4.
9939 (Limitations of Usual Tools): cp -r is now specified by Posix.
9940 Omit longwinded and obsolescent discussion of cp -f.
9941 Modernize discussion of expr, ls.
9942 (Limitations of Make): Modernize discussion of VPATH builds.
9943 Mention $? as a workaround in some cases.
9944 * doc/install.texi (Basic Installation):
9945 Mention "./configure; make; make install" first. Be more
9946 specific about why this file is generic. Remove unnecessary
9947 parens. Remove misleading "only". Remove obsolete advice
9948 about csh. Don't say "configure" takes awhile; say it
9949 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9950 and CC=c99 rather than CC=c89, as these are blessed by current
9951 Posix. Recommend GNU make if doing a VPATH build.
9953 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9955 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9956 examples involving shell prompts.
9958 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9959 and Paul Eggert <eggert@cs.ucla.edu>
9961 * doc/autoconf.texi (Here-Documents): Add details about the
9962 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9963 use "here-documents" instead of "here documents".
9965 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9967 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

9972 anywhere in directory names.
9974 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9976 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9977 about quoting the case statement, just in case.
9978 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9979 was fixed in ksh93g; reported by Ralf Wildenhues.
9981 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9983 * doc/autoconf.texi (System Services): Do not document
9984 overriding EXEEXT via ac_cv_exeext=ext.
9985 (Particular Programs) <AC_PROG_MKDIR_P>:
9986 Document that ${MKDIR_P} understands --.

9990 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9992 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
9993 argument with leading hyphen. Problem reported by Paul Eggert.
9995 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9997 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9998 about quoting ac_try: quote all of it, if any of it seems suspicious.
9999 This means we don't have to worry about ${ or sed any more.
10000 Also, double-quote the case statement, to work around misuses via
10001 underquoting as reported by Ralf Wildenhues in
10002 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10003 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10004 undocumented and dangerous macro.

10014 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10016 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10017 since evidently some packages rely on the old, broken behavior.
10018 Problem reported by Ralf Wildenhues in
10019 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10020 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10021 pre-2006-05-26 definitions, but leave in the comments that
10022 these macros are dangerous and should not be used.
10023 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10024 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10025 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10026 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10027 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10029 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10031 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10032 the use of 'tr', since this is our only use of 'tr'.
10034 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10035 and Paul Eggert <eggert@cs.ucla.edu>
10037 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10038 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10040 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10042 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10043 the output file in the `${datarootdir}' test.
10045 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10046 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10048 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10049 mention of `datarootdir' in the input file(s), but literal
10050 `${datarootdir}' in the output file, and we haven't warned yet,
10051 then warn as well: the user may have (erroneously) used
10052 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10053 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10054 * tests/torture.at (datarootdir workaround): Extend this test.
10057 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10058 and Paul Eggert <eggert@cs.ucla.edu>
10060 * doc/autoconf.texi (autoheader Invocation): The first argument to
10061 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10062 alternatives and clear up the language a bit.
10064 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10066 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10067 ac_config_guess, ac_config_sub, ac_configure.
10068 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10069 Fix typo that prevented an unnecessary space from being removed.
10070 Problems reported by Ralf Wildenhues in:
10071 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10073 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10075 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10076 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10077 Don't use the term "thread-safe" to talk about mkdir race
10078 conditions, since the problem is more a process than a thread
10079 issue. Problem reported by Stepan Kasal in:
10080 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10081 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10082 the test for 'install' more closely. Look at MKDIR_P first.
10083 Look in the PATH, and at /opt/sfw/bin.
10084 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10085 Don't bother to try mkdir -p, since we already check mkdir --version;
10086 just look at the version number. (There's no easy way to check
10087 for race-free implementations.)
10088 * tests/tools.at (autoconf: subdirectories): Adjust to above
10089 changes, since MKDIR_P now might end in "/mkdir -p".
10091 * doc/autoconf.texi (autoheader Invocation): Mention that the
10092 first arg of AC_DEFINE_UNQUOTED must be a literal.
10093 Problem reported by Ben Pfaff in
10094 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10096 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10097 * doc/autoconf.texi (Special Chars in Variables): New section.
10098 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10099 (Installation Directory Variables): Quote $(datadir) better.
10100 (Limitations of Builtins): Describe some of eval's trickiness.
10102 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10103 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10104 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10105 in front of every arg, not just trailing args. Quote apostrophes.
10106 (_AC_EVAL_ECHO): New macro.
10107 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10108 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10110 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10111 exposed by quoting of eval argument. Put the command on line line
10113 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10114 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10115 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10116 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10117 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10118 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10119 Use eval more safely.
10120 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10121 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10123 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10124 lines, exposed by quoting of eval argument.
10126 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10127 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10129 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10130 initialization of `ac_cv_exeext', do not override it if it was
10131 already set, unless it was set to `no', for compatibility with
10132 Autoconf-2.13, and comment this.
10133 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10134 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10135 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10136 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10137 Document that this test may be overridden by setting
10140 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10142 Revert these two patches:
10144 2006-04-06 Eric Blake <ebb9@byu.net>
10145 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10146 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10149 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10150 Clean up _AC_COMPILER_EXEEXT* macros.
10151 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10152 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10153 ac_file to the name of the default output file and call
10154 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10155 initial `rm' of the candidate files...
10156 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10157 the same list in subsequent `rm' calls, and for the temporary
10158 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10159 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10160 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10161 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10162 no longer needed) by libtool. Make it a cache check.
10163 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10164 copied here by mistake.
10165 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10166 _AC_COMPILER_EXEEXT.
10167 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10168 _AC_COMPILER_OBJEXT directly.
10169 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10171 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10173 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10174 Fix description of how the buggy `sed' works.
10176 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10178 Sync from Automake:
10180 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10181 ENOLCK. Only mention `make -j' when applicable. Only raise
10182 fatal errors when `make -j' is involved. Improve error message.
10184 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10186 * doc/autoconf.texi (Here-Documents): We now know more about
10187 the variable expansion in here documents bug.
10188 Thanks to Tim Rice and Stepan Kasal.
10190 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10191 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10193 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10195 * tests/autotest.at (Multiline command from M4 expansion):
10196 No failure to be expected if the shell quotes newlines in
10197 commands in the `set -x' output. Report by Tim Rice.
10200 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10202 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10203 expansion in the here-documents used by config.status, as that
10204 runs afoul of the Korn shell version M-12/28/93d bug described in
10205 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10206 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10207 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10209 2006-05-23 Jim Meyering <jim@meyering.net>
10211 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10212 Fix typo introduced with 2006-04-02 change. It reversed the sense
10215 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10217 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10218 ac_dB slightly, to save bytes in the script.
10219 Max out at 50 lines, rather than 96; this is more likely
10220 (though not guaranteed) to avoid obscure 'sed' failures.
10222 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10224 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10225 `tr -d -' as bad option argument. Work around this by deleting
10226 an unrelated character.
10227 Report by Tim Rice <tim@multitalents.net>.
10229 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10230 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10231 Stepan Kasal <kasal@ucw.cz>
10233 * doc/autoconf.texi (Particular Programs): Do not promise that
10234 we always prefer the GNU version of the program, and that we
10235 search according to PATH; both rules can have exceptions.
10236 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10237 AC_PROG_SED. Move descriptions of limitations
10238 to the Limitations of Usual Tools section.
10239 (Limitations of Usual Tools) <sed>: Mention script length
10240 limitations with Solaris /usr/ucb/sed.
10241 <grep>: Fix wording for empty alternative. Mention that -c and
10242 -l should not be combined, and that -E and -F should not be
10245 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10246 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10248 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10249 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10251 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10253 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10254 AC_DEFINE is now passed to m4_pattern_allow.
10255 * NEWS: Mention that; likewise for AC_SUBST.
10256 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10257 the parameter to m4_pattern_allow.
10258 * tests/tools.at: Add a check for that.
10260 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10262 * lib/autoconf/status.m4: Fix typos.
10264 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10266 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10267 only the files that this macro generates.
10269 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10271 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10272 the HP-UX sed limitation of 99 commands, labels do not count.
10273 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10275 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10277 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10279 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10280 Import the following fix from coreutils:
10282 2006-01-13 Jim Meyering <jim@meyering.net>
10284 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10285 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10286 not double-quote uses of that variable, to accommodate the rare
10287 case in which getmntent is available in none of the libraries
10288 checked. This happens at least on FreeBSD 5.0.
10290 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10292 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10293 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10294 some other programs unwisely rely on these undocumented vars.
10295 But put in warning comments about them.
10296 Problem reported by Ralf Wildenhues in
10297 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10298 * NEWS: Document that these variables are intended to go away.
10300 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10302 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,

10307 * doc/autoconf.texi (C++ Compiler): Document it.
10308 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10311 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10313 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10314 that caused config.status to generate 100-command sed scripts; the
10315 portable limit is 99.
10317 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10319 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10320 variable `ac_d' instead of `d' to avoid infringing namespace.
10321 Report by Ralf Menzel.
10323 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10325 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10326 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10327 * tests/tools.at (autoconf: subdirectories): New test, taken from
10328 the corresponding problem report by Ralf Wildenhues in:
10329 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10331 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10332 Quote some uses of shell variables if they might suffer unexpected
10333 globbing. This doesn't fix all instances of quoting problems that
10334 I found, just the easy ones that look safe.
10335 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10336 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10337 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10338 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10339 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

10346 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10348 * bin/autoreconf.in ($help): Reword according to the manual.
10349 Suggested by Olly Betts.
10351 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10352 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10354 * bin/autoreconf.in: Pass the directory argument to
10355 `require_configure_ac'. Fix comment.
10356 * tests/torture.at (Configuring subdirectories): Expose this.
10357 Reported by Olly Betts.
10359 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10361 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10362 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10363 Automake as follows:
10365 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10366 `$configure_in' instead of `configure.in', to preserve
10367 directory component.
10369 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10371 * config/config.guess, config/config.sub, config/texinfo.tex,
10372 doc/make-stds.texi, doc/standards.texi: Sync from upstream.

10376 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10377 test for C99 conformance; (bool) 0.5 is an integer constant
10378 expression, but (bool) -0.5 is not. Problem reported by Fedor
10379 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10381 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10383 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10384 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10385 Warn about obsolete install-sh files. Remove stray sentence
10386 fragment and fix cross reference.
10387 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10388 install -d; this undoes the 2006-05-10 change.
10389 (MKDIR_P): Mark with AN_MAKEVAR.
10390 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10391 that we don't require $INSTALL to be thread-safe. Move comments
10392 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10393 of AC_PROG_INSTALL. Output a message saying that we're checking
10394 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10395 MKDIR_P instead of AC_SUBST.
10396 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10397 Special magic for MKDIR_P, too.
10398 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10400 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10402 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10404 Sync from Automake, as follows:
10406 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10407 * config/install-sh: Initialize IFS, so field splitting isn't
10409 * config/mkinstalldirs: Likewise.
10410 * config/missing: Remove superfluous quotes. Replace all uses of
10411 `[' by `test', for consistency, and for..
10412 * config/missing (sed_minuso, sed_output): New variables.
10413 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10414 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10415 Fixes `missing' to detect `--output' for help2man. Fixes
10416 PR automake/483. Report by Dennis J. Linse.
10417 (autom4te): Document in `missing --help'.
10419 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10421 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10422 * config/install-sh: Don't use 'path' to talk about file names,
10423 as per GNU coding standards. Close a race condition reported by Ralf
10424 Wildenhues and Stepan Kasal. There is still a race condition
10425 on hosts that predate Posix 1003.1-1992, but we can't help this.
10426 Don't mishandle weird characters like space on pre-Posix hosts.
10427 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10428 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10429 AC_PROG_MKDIR_P from AS_MKDIR_P.
10430 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10431 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10432 earlier editions are not (including Automake 1.8.3).
10433 Do not suggest mkinstalldirs for thread-safety.
10434 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10435 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10436 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10437 presence of special characters and race conditions.
10438 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10439 in Autoconf's name space.
10441 2006-05-10 Bruno Haible <bruno@clisp.org>
10442 and Paul Eggert <eggert@cs.ucla.edu>

10448 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10450 * config/install-sh: Update to Automake CVS version, as follows:
10451 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10452 * lib/install-sh: Simplify the expr implementation of dirname.
10453 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10454 * lib/install-sh: Handle --, and diagnose unknown options.
10456 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10458 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10459 `./autom4te' to create `./testsuite', since the `all' target
10460 will ensure its presence, but `installcheck' should not create
10461 the uninstalled wrappers.
10463 * tests/torture.at (Unusual Automake input files): Skip if we
10464 detect automake < 1.8.
10466 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10468 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10469 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10470 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10473 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10475 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10476 munge (multiple) white space and other oddities.
10477 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10478 single quotes in variable assignment.
10479 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10480 and similar failures by adding multiple spaces, tabs, and other
10481 special characters.
10482 Report and different test suggested by Francesco Romani
10483 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10485 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10486 single quotes, we only need to search for single quotes; this
10487 both simplifies the search pattern, and makes us less
10488 susceptible to `echo' variations for arguments not containing
10490 (_AC_ARG_VAR_VALIDATE): Likewise.
10492 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10494 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10495 `$*' and IFS concatenation issue with traditional shells and
10496 bash-2.04. Report by Seanster@Seanster.com.
10498 2006-05-03 Bruno Haible <bruno@clisp.org>
10500 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10501 precisely which Mac OS X versions have the od problem.
10503 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10505 * doc/autoconf.texi: Use @option systematically.
10507 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10508 and Bruno Haible <bruno@clisp.org>
10510 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10512 (Integer Overflow): Mention the special case of integer division
10515 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10517 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10518 traditional shells like the Solaris one that do not use the
10519 first IFS character for assembling `$*'.
10520 Prompted by a related report from autoconf_bug@nro.ca.
10522 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10523 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10525 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10526 Mention more problems with the -e option.
10528 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10531 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10533 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10534 in URLs to improve DVI formatted output (requires texinfo 4.6).
10535 (System Services, Systemology, Shellology): Likewise.
10536 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10539 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10541 (Runtime): Fix macro argument names to match description:
10542 `action-if-found' -> `action-if-true' and similarly.
10543 (Obsolete Macros): Likewise.
10544 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10545 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10546 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10548 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10550 * doc/autoconf.texi (Limitations of Make): Clean up markup.
10553 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

10565 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
10566 (Integer Overflow, Null Pointers, Buffer Overruns):
10567 (Floating Point Portability, Exiting Portably): New sections.
10568 (Writing Test Programs): Fix some langauge. Recommend exiting
10569 with status 1, not merely nonzero. Clarify exit declaration.

10576 * bin/autoconf.as (me): Replace by as_me.
10578 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10580 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10581 since as_me isn't set yet.
10583 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10585 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10586 a few minor bugs in this area.
10588 * doc/autoconf.texi (Programming in M4sh): Comment out the
10589 documentation of AS_BASENAME, for now.
10590 (Shell Substitutions): Do not use AS_DIRNAME in an example.

10593 * bin/autoconf.as (me): Don't use AS_BASENAME.
10594 (dir): Remove the unused variable.
10595 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10596 AS_DETECT_REQUIRED. All uses changed.
10597 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
10599 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

10609 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10611 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10612 of "run time" and "run-time" changed to "runtime", for consistency.

10621 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10623 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10624 Archive is not officially `GNU' any more. Update URL.
10625 (Defining Directories): Likewise
10626 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10628 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10630 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10631 newline from the `trap' code to finish `config.log'; the NetBSD
10632 /bin/sh resets the exit status after an empty command, as
10633 documented in doc/autoconf.texi.
10634 Reported by Dalibor Topic <robilad@kaffe.org>.
10636 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10638 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10639 Suggested by Bruno Haible.
10641 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10643 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10644 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10645 Instead, just list the shells that we know work.
10646 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10647 changed. Be more cautious about the _cv_ variable.
10648 * tests/tools.at (Syntax of the shell scripts): Check the
10649 _cv_ variable once, at first, to avoid an internal autoconf error
10650 when sh -n does not work.
10652 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10654 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10656 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10658 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10659 use ">&-" since we're only 99.999% sure that this is portable,
10660 and since the MinGW bug is fixed in a different way.
10661 * lib/autotest/general.m4 (AT_INIT): Likewise.
10663 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10665 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10666 before opening config.log, to avoid hitting a bug on MinGW.
10668 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10670 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10671 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10672 This works around a MinGW bug reported by Eric Paire.
10673 Make sure that all writes to the log file append to it,
10674 rather than possibly losing data.
10675 * lib/autotest/general.m4 (AT_INIT): Likewise.
10677 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10679 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10682 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10686 * configure.ac (AC_INIT): Bump to 2.59d.
10688 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10692 * Makefile.maint (news-date-check): Do not require a leading `*'
10693 before the release date in NEWS.
10695 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10696 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10698 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10699 the instantiated file do not contain the string 'datarootdir'
10700 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10701 @mandir@, replace the reference '${datarootdir}' by the value.
10702 * tests/torture.at (datarootdir workaround): New test.
10703 * NEWS: Advertise this temporary fixup.
10704 Based on a patch by Bruno Haible, reported and analyzed by
10705 Paul Eggert and Noah Misch.
10707 2006-04-12 Eric Blake <ebb9@byu.net>
10709 * tests/autotest.at (Debugging a failed test): Fix comment.
10711 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10713 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10714 all the changes since 2006-04-07.
10716 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10718 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10719 succeeded, but `ln -s file dir' failed, take care to remove the
10720 leftover target before the next test, to prevent its spurious
10721 failure; also make sure `ln file dir' works before selecting it.
10722 Thanks to Keith Marshall for pointing this out.
10725 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10726 assignments in `at_debug_args', so that we put them correctly
10727 in the `run' script.
10728 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10729 Reported by Eric Blake.
10731 2006-04-11 Eric Blake <ebb9@byu.net>
10733 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10734 top-level tests after micro-suite has been run. Used in...
10735 (Debugging a successful test, Debugging script and environment),
10736 (Debugging a failed test): ...these new tests. The first of these
10738 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10739 macro, split out from...
10740 (AT_INIT): ...here, so that using -d also generates a run script.
10741 Document that -d inhibits top-level logging.
10742 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10743 inhibits top-level logging; debug scripts are created.
10745 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10747 * tests/autotest.at (Empty test, Empty check): New test to check it.
10749 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10752 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10754 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10755 the files if a problem appears. Make the empty *.at files
10756 read-only, too. Proposed by Ralf Wildenhues.
10758 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10760 * config/Makefile.am: Add comment to force updated Makefile.in.
10762 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10763 space only patch to this file, this patch causes the Makefile.in
10764 files that include freeze.mk to be updated, and thus have a
10765 newer time stamp again, which in turn makes a pristine CVS
10766 checkout have correct time stamps.
10768 * Makefile.maint (cvs-sv): New macro, to be used..
10769 (config.guess-url_prefix, config.sub-url_prefix)
10770 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10771 point to CVS text checkout of Gnulib files.
10772 (copyright-check): Bump current year.
10773 (announcement): Do not hard-wire `./announce-gen'.
10774 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10776 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10778 (wget_files): Update config.guess, config.sub, texinfo.tex by
10779 `wget-update', now that their URLs work again.
10781 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10783 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10784 Problem noted by Paul D. Smith.
10786 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10788 * doc/autoconf.texi: Remove unused words from word list.
10789 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10790 .x-sc_trailing_space: New files.
10792 * doc/standards.texi: Sync from gnulib.
10794 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10795 `LIBOBJDIR' as experimental.
10797 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10798 with a target directory; it's internally implemented as `cp'
10799 anyway, but since Autoconf advertises the possibility to use
10800 a target directory when LN_S is `ln -s', we need to find out.
10801 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10802 analyzed by Keith Marshall <keith.marshall@total.com>.
10806 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10808 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10809 confdefs.h as-is. In general, if it has backslash-newline or the
10810 like, then it doesn't work either to sort or to remove empty
10813 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10815 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10817 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10819 * lib/autom4te.in (Automake-preselections): Preselect
10822 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10824 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10825 apostrophe within a single-quoted string, as this is the usual
10826 tradition and is easier to read than '"'"'. Don't rely on the
10827 shell treating "$/" like '$/'. Use a more-consistent indenting
10828 style for the trap.
10830 2006-04-09 Eric Blake <ebb9@byu.net>
10832 * tests/autotest.at (Backquote command substitution),
10833 (Multiline backquote command substitution): Remove mistaken
10834 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10836 (Parenthetical command substitution, Multiline parenthetical
10837 command substitution): here.
10839 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10841 Import macros from gnulib (often changing their name).
10843 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

10868 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
10869 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10870 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10871 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10872 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10873 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10874 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10875 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10876 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10877 (Coding Style). Don't mention m4_expand_once.
10878 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10888 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10889 Catch a bug in an HP-UX C compiler.
10890 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

10898 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10899 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10901 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10903 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10904 of the warning introduced by the 2001-08-28 change.
10906 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10907 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10909 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10910 variables shall be overriden by the cache.
10911 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10912 that contains braces.
10914 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10916 Revert the patch from 2006-04-01 and only improve
10917 _AS_DETECT_BETTER_SHELL:
10919 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10920 skip nonexistent directories.
10921 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10922 only shell candidates which exist.
10923 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10924 * lib/autotest/general.m4 (AT_INIT): No need to give three
10925 parameters to _AS_PATH_WALK.
10927 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
10928 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10930 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
10931 distinguish m4sugar macros.
10932 * tests/tools.at (autoupdating with aclocal and m4_include):
10933 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10934 test case by Noah Misch <noah@cs.caltech.edu>.
10936 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10938 Revert my change from 2006-03-17, in other words:
10939 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10941 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
10942 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
10945 2006-04-07 Eric Blake <ebb9@byu.net>
10947 * doc/autoconf.texi (Programming in M4sh): Document that
10948 AS_MKDIR_P exits the script on failure.
10949 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10951 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10953 * config/elisp-comp, config/install-sh, config/mdate-sh,
10954 config/missing, config/mkinstalldirs: Sync from Automake.
10956 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
10959 * doc/make-stds.texi: Sync from gnulib.
10961 2006-04-06 Eric Blake <ebb9@byu.net>
10963 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10964 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10967 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
10968 Eric Blake <ebb9@byu.net>,
10969 Paul Eggert <eggert@cs.ucla.edu>,
10970 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10972 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10973 whether `set' quotes correctly: redirect stderr of the tested
10974 `set', and use a subshell, for Ultrix; use `sed' instead of
10975 `grep' for zsh `set' which may write binary output; match only
10976 at the beginning of a line, to avoid false positives.
10977 In order to avoid false positives by unrelated variables with
10978 multiline content, put the dump algorithm in a subshell and
10979 unset all variables containing newlines (except some which are
10980 special to the shell). Warn about cache variables that are
10983 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10985 * config/config.guess, config/config.sub, config/texinfo.tex:
10986 Sync from upstream.
10988 * tests/mktests.sh: Reword comments.
10990 * tests/mktests.sh: Only skip internal macros starting with
10991 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10992 Update exclusion lists for the test suite to this end:
10993 (AC_ARG_VAR): Do test this now.
10994 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
10995 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
10996 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
10997 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
10999 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
11000 shell issue with double-quoted command substitutions of native
11002 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
11005 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

11015 * lib/autoconf/lang.m4: Remove trailing space.
11017 * lib/autoconf/status.m4: More replacements to
11018 <tab><space> where this makes sense.
11020 2006-04-06 Stepan Kasal <kasal@ucw.cz>
11022 * tests/Makefile.am (maintainer-check-posix):
11023 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
11025 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
11026 ac_config_<foo>s again, sometimes normalized, sometimes not.
11027 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11028 (AC_CONFIG_COMMANDS): Do not do so here.
11029 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11030 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11031 2005-07-25 rewrite. Noticed by Noah Misch.
11033 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
11034 _AC_PRESERVE_HELP_ORDER, ...
11035 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
11037 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
11038 inside m4_expand_once; it is redundant.
11040 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
11041 for --help from Cygnus `configure.'
11043 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
11045 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
11046 on a patch proposed by Ralf Wildenhues.
11048 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11050 * lib/autoconf/status.m4: Replace <space>''<tab> with
11051 <tab><space> where this makes sense.
11053 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
11054 Noah Misch <noah@cs.caltech.edu>
11056 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
11057 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
11058 * doc/autoconf.texi (Help Formatting): New node.
11059 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
11061 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11063 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
11064 lib/autoconf/specific.m4, lib/autoconf/status.m4,
11065 lib/autoconf/types.m4, lib/autotest/general.m4,
11066 tests/mktests.sh, tests/torture.at: White space cleanup:
11067 remove some SPACE before TAB, or add quoting ('' or @&t@).
11069 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
11071 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
11073 2006-04-05 Eric Blake <ebb9@byu.net>
11075 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
11076 empty test suite works.
11077 * tests/autotest.at (Empty test suite): Remove xfail.
11079 2006-04-05 Noah Misch <noah@cs.caltech.edu>
11081 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
11082 TAGS to ac_config_<foo>s.
11083 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
11084 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
11085 normalizing it, consistent it with previous releases.
11086 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
11088 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11090 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
11091 Use simplified args that Eric Blake originally suggested.
11093 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
11095 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
11096 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11097 Use 'comm' rather than N instances of grep; this also fixes a bug
11098 whereby substrings were incorrectly matched, causing us to not
11099 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
11100 (exclude_list): Exclude empty macros.
11101 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
11103 Use awk rather than grep -E or egrep, to avoid
11104 portability problems with regular expressions containing newlines.
11105 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
11106 Switch from grep to awk syntax.
11107 (ac_exclude_script): Renamed from ac_exclude_egrep.
11108 (au_exclude_script): Renamed from au_exclude_egrep.
11110 2006-04-04 Noah Misch <noah@cs.caltech.edu>

12024 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12026 * config/move-if-change: Don't output "$2 is unchanged";
12027 suggested by Ben Elliston. Handle weird characters correctly.
12029 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12031 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12032 calls, so that the final expansion of this macro is shorter.
12033 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12034 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12035 the cleanup there. Use AS_VAR_* macros, to be more general.
12036 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12038 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12040 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12042 2005-09-01 Stepan Kasal <kasal@ucw.cz>

12053 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12055 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12056 The previous patch didn't work, so try a better one.
12058 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12060 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12061 in the example. Reported by Bruno Haible.
12062 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12063 "if $undefined_var;" succeeds with my shell.
12065 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12066 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12067 but change the m4_divert_text to m4_divert_once.
12069 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12071 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12072 Work around bug in Solaris /usr/xpg4/bin/awk.
12073 The bug is present in at least Solaris 8 through 10.
12075 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12077 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12078 some evil values and relying on the fact that $* concatenates the
12079 parameters by the first character from IFS.
12081 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12082 Stepan Kasal <kasal@ucw.cz>
12084 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12085 first header appears, define AH_HEADER.
12086 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12087 Update limitations about when to call AC_CONFIG_HEADERS.
12088 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12089 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12090 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12091 ``Configuration Actions''; fix their index entries.
12093 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12094 options correctly. Process N-M as M-N if M is smaller than N.
12095 Process ranges correctly so that N-N will run only N.
12096 Sort and uniquify the tests that will be run. If there is more
12097 than one test, reinsert the banners for the tests.
12098 * tests/autotest.at (Keywords): Unmark XFAIL.
12100 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12102 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12103 before passing the macro name to AH_TEMPLATE.
12105 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12106 now opens log after option processing; in particular, --version
12107 and --help do not touch config.log.
12109 * Makefile.maint: Revert the change from 2005-08-12.
12111 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12113 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

12126 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12128 When building in place, set srcdir="."; suggested by Tim Van Holder.
12130 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12131 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12132 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12133 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12134 does not mean "no --srcdir option".
12136 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12138 * tests/autoscan.at (autoscan): New file.
12139 * tests/suite.at: Use it.

12143 * tests/autotest.at (Keywords): Test keywords combinations.
12145 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12147 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12148 add "2>&1"; gzip 1.2.4 prints help on stderr.
12150 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12152 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12153 was pushdef'ed twice while popped only once. Push it only once.
12154 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12156 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12158 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

12163 * Makefile.maint: Update from Bison.
12165 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12166 "<tab>" in comment, so that the point is understandable.
12168 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12170 Rewrite substantial part of lib/autoconf/status.m4.
12171 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12172 and CONFIG_COMMANDS are not processed in four separate loops.
12173 Instead, there is one main loop. This alows that the common code
12174 is expanded only once, thus config.status (and configure) is smaller.
12176 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12177 the AC_LIST_FILES and cousins macros are no longer used.
12179 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12180 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12181 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12182 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12183 contain the initialization, nor the for loop, nor the associated
12184 commands; all these go to ...
12185 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12186 _AC_OUTPUT_CONFIG_STATUS.
12187 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12188 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12189 (_AC_OUTPUT_FILE): The creation of the sed script ...
12190 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12191 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12192 _AC_OUTPUT_MAIN_LOOP.
12193 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12194 _AC_CONFIG_COMMANDS): Use ...
12195 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12196 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12197 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12198 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12199 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12200 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12202 (_AC_CONFIG_UNIQUE): Update.
12203 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12204 Replaced by this ...
12205 (_AC_LIST_TAGS): ... new common macro.
12206 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12207 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12208 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12209 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12210 this didn't belong to the `config commands' section.
12211 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12212 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12213 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12214 to the `config commands' section either.
12215 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12216 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12218 ... and many changes to the comments nearby.
12220 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12221 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12222 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12223 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12224 (#define header templates): The comment at the top of the generated
12225 header now includes the name(s) of the source file(s).
12227 Several unrelated small changes:
12229 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12230 parameter to AC_DIAGNOSE.
12231 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12232 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12233 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12234 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12235 with AU::AC_OUTPUT.
12236 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12237 in AC_OUTPUT doesn't double-quote it either.
12238 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12241 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12243 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12244 versions of Portland Group compiler produce single- and double-quoted
12245 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12246 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12248 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12250 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12251 This is a corrected version of yesterday's patch.
12253 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12255 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12256 path, too; insert a "===" to emphasize the line.
12258 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12259 ac_cv_build_alias to ac_build_alias.
12260 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12262 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12263 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12264 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12265 (AC_ARG_VAR): ... here.
12266 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12269 Keep a list of all precious variables and process them with one simple
12270 for loop, instead of expanding all commands, or, OTOH, complicated
12271 processing of output of "set".
12272 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12273 variable names in new macro...
12274 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12275 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12276 a loop to assign all ac_env_* and ac_cv_env_* variables.
12277 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12279 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12280 its value to shell variable ac_precious_vars and call
12281 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12282 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12283 _AC_ARG_VAR_VALIDATE.
12285 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12286 and the AC_SUBSTs ...

12304 They are generated by the Tru64 v5.1B shell.
12306 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12308 Fix my changes from 2005-07-01; reported by Noah Misch.
12309 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12310 description, the macro now accepts only a single tag.
12311 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12313 Fix cases when the varsions of Autoconf and Autotest don't match.
12314 Reported by Noah Misch.
12315 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12316 at_top_builddir, for compatibility with older autotest.
12317 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12318 is not set, use at_top_builddir, for compatibility with older
12319 versions of autoconf.
12321 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12323 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12324 Problem reported by Patrick Welche.
12326 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12328 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12329 sed substitution command, so that we allow | in program prefixes
12330 and program suffixes. (& is a problem anyway; we're not fixing

12333 configure_input, top_builddir, srcdir, etc.
12334 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12335 PATH_SEPARATOR in AUTOTEST_PATH.
12337 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12339 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12340 for loop over config.site files using `set', to allow
12341 directory names containing IFS characters.
12343 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12345 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12346 directories with weird names. Apparently some people like living
12347 on the edge. However, improve the test that "pwd" actually does
12348 report a name for the working directory.
12349 * NEWS: Remove the claim that we test for funny chars in dir names.
12351 2005-07-01 Stepan Kasal <kasal@ucw.cz>

12365 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12367 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12368 document to output the default config_* lists to config.status.
12369 Don't recognize option --file, if the functionality is not there.
12370 Likewise for --header; moreover, recognize --he and --h as shortcuts
12371 for --help in that case.
12373 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12374 matches the order of execution. No code changed.
12376 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12378 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
12379 single-quoted -cmdline argument in Portland Group compiler.

12386 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12388 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
12389 descriptors to child processes; reported by Norman Gray.
12391 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12393 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12395 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12396 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12397 (AC_SUBST): Call it.
12398 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12399 the directory specific variables; but don't call it for configure_input.
12401 2005-06-28 Derek Price <derek@ximbiot.com>
12403 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12406 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12408 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12409 directory have inherent problems with special characters like spaces,
12410 due to limitations in Make syntax. Problem reported by Alexandre
12412 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12413 Also, fix Tru64 porting problem with shell patterns,

12424 Fix some more shell quoting problems. Prompted by a bug report
12425 from Justace Clutter.
12426 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12427 variable into diagnostic. Make the diagnostic an error, not a warning,
12428 because we really don't support spaces and suchlike in dir names.
12429 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12430 Don't worry about backslashes in srcdir; it can't happen now.

12441 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12443 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12444 that '\|' is not allowed in BREs; recommend using newline separated
12445 list of patterns instead of multiple -e options.
12447 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12449 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
12451 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

12455 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12457 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12458 b, t, r, w commands require single space, while : cannot have any.
12459 (Special Shell Variables): Fix sed code this in the example.
12460 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12461 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12463 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12464 expand to the empty list. Don't use two pairs of m4_changequote,
12465 it's not necessary.
12467 2005-06-20 Derek Price <derek@ximbiot.com>
12469 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12471 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12473 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12474 * doc/autoconf.texi:
12475 Don't mention Solaris versions so much, if a
12476 problem is common to all extant versions of Solaris. Say "SunOS
12477 4" instead of "SunOS" for SunOS 4.
12478 (awk): Mention more of the limitations of traditional Awk.
12479 (cat): Don't talk about cat -v.
12481 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12483 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12484 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12485 but the implementation is entirely different and is designed
12486 to be compatible with glibc strverscmp.
12487 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12489 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12490 on Mac OS X 10.4 reported by Peter O'Gorman in:
12491 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
12492 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12493 Use shell builtins rather than 'expr', to work around expr bug.
12495 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12497 * doc/autoconf.texi: "filesystem" -> "file system".
12498 "behaviour" -> "behavior".
12499 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12500 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12502 * lib/m4sugar/m4sh.m4: Likewise.
12503 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12504 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12506 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12507 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12508 to update the man page. That way, we don't have to check in new
12509 man pages every month.
12511 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12512 quotes and backslashes. Patch from Derek Price.

12516 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
12519 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
12521 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12522 -u, since it outputs chatter if the input files are the same.
12523 Problem reported by Ralf Menzel.
12525 2005-06-08 Derek Price <derek@ximbiot.com>
12527 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12528 renaming them since they are about to be redefined anyhow.
12530 2005-06-08 Derek Price <derek@ximbiot.com>
12532 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12533 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12534 Move m4_undefine to alphabetical order.
12536 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12538 * README: Recommend GNU M4 1.4.3 or later.
12539 * doc/autoconf.texi (Introduction): Likewise.
12540 Reword to avoid some formatting glitches.
12541 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12542 Clarify explanation of HP compiler bug.
12543 Redo example output tp match current CVS snapshot.
12544 Use @example.org in email addresses when the examples
12545 might get inadvertently cut-and-pasted into user code.
12546 Remove example of autom4te usage that doesn't seem to work now.
12547 Use modern AC_INIT (except when the example is meant to be
12548 shown with Autoconf 2.13).
12549 Update ksh info for Solaris 9 and later.
12551 Modernize description of Automake versions a bit.
12552 Don't claim a future version of Autoconf is near.
12553 * doc/install.texi: Reword to avoid some formatting glitches.
12555 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12557 * doc/autoconf.texi: Add [] to examples, so that the manual
12558 follows its own advice about quoting better.
12559 Reword to avoid some formatting glitches.
12560 * doc/installt.exi: Reword to avoid some formatting glitches.
12562 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12563 Tru64 ksh pattern matching bug. Reported against Libtool by
12564 Albert Chin <libtool@mlists.thewrittenword.com> and
12565 Nicolas Joly <njoly@pasteur.fr>.
12567 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12569 m4_cdr of one-member list was [[]] (one-member list containing an
12570 empty string) instead of [] (an empty list. Callers were skewed to
12571 match this misbehaviour. As a consequence of this:
12572 - m4_foreach([x], [], [foo]) expanded to `foo', while
12573 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12574 This bug has been fixed:
12576 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12577 expand to an empty string; print error msg if called without
12579 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12580 misbehaviour; handle [] and [[]] correctly.
12582 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12584 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12585 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12586 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12588 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12590 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12591 swallow records with more than 99 fields.
12592 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12593 parse the long line.
12595 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12597 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12598 swallow literals longer than 399. Reported by Ralf Wildenhues.
12599 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12600 to workaround this limitation.
12602 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12604 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12605 to gfortran, and make these the first two compiler names
12606 checked (following the general autoconf preference for gcc).
12608 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12610 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12611 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12612 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12614 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12616 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12617 expression of unbounded size when processing the --list
12618 option. This runs afoul of a limit of 399 bytes per regular
12619 expression on AIX. Problem reported by Ralf Wildenhues.
12621 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
12623 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
12624 * doc/autoconf.texi (Particular Headers): Reword example
12625 for multiline stdbool replacement.
12626 (Setting Output Variables): Reword text a bit. Don't
12627 give all the details about |#_!!_#|.
12628 Reword description of line replacement.
12630 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12632 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12633 now contain newlines, and substituted files must be referenced on
12634 a line alone; the sed scripts to substitute them are now very
12636 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12637 commands can be put in a sed script portably.
12638 * doc/autoconf.texi (Setting Output Variables): Document above
12639 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12640 use of multiline substitution.
12641 * tests/torture.at: No longer expect substitution of newline to fail.

12645 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
12646 From Ralf Menzel (trivial change).
12648 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12650 * tests/local.at: Don't attempt to check for negated character
12651 classes in shell scripts. The test was too brittle.
12653 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12655 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12656 * doc/autoconf.texi (Limitations of Builtins): Document this
12659 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12661 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12662 common code; used in many places in the tree.
12663 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
12664 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
12666 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12668 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12669 messages when ac_unique_file is not found.
12670 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12671 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12672 commands, for consistency with AC_MSG_ERROR and such.
12674 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12676 * bin/Makefile.am: Merge the two rules for creating scripts.
12678 2005-05-23 Stepan Kasal <kasal@ucw.cz>
12680 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
12681 obsolete; it was never documented.
12682 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
12684 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12686 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12687 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12688 (ac_top_builddir): ... this ...
12689 (ac_top_build_prefix): ... to this; the old name is also kept, for
12690 backward compatibility.
12691 (ac_top_builddir_sub): New variable, without the trailing slash,
12693 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12694 * doc/autoconf.texi (Configuration Actions): Rename
12695 ac_top_builddir to ac_top_build_prefix.
12696 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

12705 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12707 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12708 argument to m4_foreach. I guess it was necessary in the past,
12709 but I think it's a no-op now.
12711 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12713 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12714 ``cat <<_ACEOF'' commands to one.
12715 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12716 * lib/autoconf/status.m4: On various places, use expr instead of
12718 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12719 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12720 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12722 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12723 the wrong patterns between ``case'' and ``esac.'' The previous
12724 code had false positives.
12726 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12728 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

12793 quoting rules. Problems noted by Stepan Kasal.
12794 Also, throughout this document, be more careful about white space.
12795 "blank", "white space", and "space" all have different meanings
12796 and we should be careful to say what we mean.
12798 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12800 Fix C++ related problems reported by Werner Lemberg.
12801 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

12835 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12836 by AC_DEFINE; it was a mistake.

12843 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12845 * doc/autoconf.texi (External Software): Quadrigraphs are not
12846 processed correctly in AS_HELP_STRING; avoid this in the examples.
12847 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12848 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12849 comment and reduce m4_default([foo], []) to [foo].
12850 (m4_strip): Update the explanation.
12852 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12854 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12855 Remove core.conftest.* too; it's generated by Tru64 5.1.
12856 Problem reported by Jennis Pruett.
12857 * lib/autoconf/functions.m4
12858 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12859 Don't bother to remove core files; AC_RUN_IFELSE should do that
12862 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12864 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12906 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12907 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12908 whole-archive (-zallextract, -zdefaultextract) options in the hope of

12914 * NEWS: The configure command now warns you if you attempt to use
12915 a directory whose name contains a special character like space,

12932 ac_pwd, and quote srcdir.
12933 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12935 * doc/autoconf.texi: Fix some systematic formatting problems.
12936 ".)" needs a following @: if not at the end of a sentence, and
12937 similarly for "!)". "etc." should be preceded by a comma.
12938 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.

12942 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

12945 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12947 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the

12952 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12954 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12955 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12956 from a Common Lisp's `cl'.
12957 (AC_PROG_CXX): Behave according to the documentation: don't
12958 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12959 make the variable CCC precious; use `cl.exe', not `cl'.

12962 Alexandre Duret-Lutz <adl@gnu.org>
12964 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12965 /dev/null, as "configure" shouldn't read stdin, and this insulates
12966 us from problems (e.g., when testing for "cl"). Also, do this
12967 redirection before invoking "hostname" or "uname", and keep the
12968 original input stream available via...
12969 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12970 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

12982 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12983 newline if neither \c nor -n work, as that would output two
12984 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12986 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12988 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12989 This causes that any required macros inside will get before the if.
12990 * doc/autoconf.texi (autom4te.cache): A typo.
12992 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12994 Undo previous change, except keep the change to
12995 lib/autoconf/programs.m4 that replaced grep with shell
12996 pattern-matching. This is because net-snmp configure reads stdin.

13001 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13002 from /dev/null, as "configure" shouldn't read stdin, and this
13003 insulates us from problems (e.g., when testing for "cl").
13004 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13005 before invoking "hostname" or "uname".
13006 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13007 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.

13009 "</dev/null" since it's now done at the top of 'configure'.

13011 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13012 Also, replace grep with shell pattern-matching, to save a process.

13035 Fix some @code's that should have been @env's, and vice versa.
13036 Sort environment variable names.
13037 Mention that shells no longer inherit IFS.
13038 Don't recommend PATH_SEPARATOR=';' so strongly.
13039 Mention that $RANDOM might expand to the empty string.

13180 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13181 Update the long comment explaining it.
13183 m4_require no longer writes an ``is required by'' line to the
13184 execution stack. It contains only one bit of non-redundant
13185 information: that the macro was required, not called. And even
13186 this bit is useless in most situations: have you ever met a macro
13187 which both calls and requires the same macro?
13189 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13190 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13237 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13238 Warn about newline stripping in `` and $(). Update Solaris
13240 (Limitations of Builtins): Use expr "X...", not expr "x...", as
13241 X insulates us from future changes to Posix.

13291 (_m4_divert_n_stack): New macro; the expansion is
13292 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
13294 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13295 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13296 stored in _m4_divert_diversion or _m4_divert_dump.
13297 (m4_divert_pop): When the parameter is given, compare the symbolic
13298 name with the last diversion pushed on the stack. Previously, the
13299 current diversion was compared with the numeric value of the
13300 diversion given as the parameter.
13301 (m4_require): If the macro hasn't been expanded yet, call ...

13609 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13610 "char c = '\200';" rather than "char c = 0x80;" as the

13791 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13792 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13793 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13794 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13796 More fixes to support spaces in the name of the build directory.
13797 This isn't a complete fix but it's an improvement.
13799 * bin/autoconf.as (autom4te_options): New var.
13800 Use it instead of appending to AUTOM4TE, so that we can allow
13801 spaces in the build directory's absolute name.
13802 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13803 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13804 AT_CHECK_NOESCAPE): Likewise.
13805 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13806 main program): Likewise.
13808 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
13810 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

13814 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
13816 * doc/autoconf.texi (Function Portability): Document isinf and
13817 and isnan. From a suggestion by Kevin Ryde.
13819 * lib/Autom4te/General.pm (END): Return correct exit status even
13820 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13822 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13824 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13825 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13826 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13828 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13830 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13831 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13832 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13833 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13834 * lib/autom4te.in (Automake-preselections): Preselect
13835 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13837 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13839 * lib/autom4te.in (Automake-preselections): Preselect
13840 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13843 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13845 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
13847 * doc/autoconf.texi (Shellology): Mention BIN_SH.
13848 Document problem with "`""`" in pdksh POSIX mode.
13850 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13852 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13853 with pdksh, too. Problem reported by Patrick Welche via
13855 * doc/autoconf.texi (Shellology): Note that set -o posix is
13856 useful for pkdsh, too.
13858 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13860 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13861 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13862 Don't fail if ENV or BASH_ENV is readonly.
13863 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13864 etc. are read only. Problem reported by Ludovic Courtes.
13866 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13868 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13869 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13872 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13874 * doc/autoconf.texi (File System Conventions): Warn about
13875 names like "aux". Problem reported by Eric Blake.
13877 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13878 by zero instead of array size, so that we can use any arithmetic
13879 constant expression (instead of requiring an integer constant
13880 expression). This allows us to test expressions like DBL_MAX <
13881 LDBL_MAX, which didn't conform to the C standard using the old
13883 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13884 now that we can do floating-point tests at compile time.
13886 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13888 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13889 and LDBL_EPSILON, as the resulting expression isn't an
13890 integer constant expression and violates the C standard.
13891 Problem reported by Nelson H. F. Beebe. Also, check
13892 for "L" suffix, and check that long double doesn't have
13893 worse range or precision than double, that mixed-mode
13894 arithmetic doesn't generate a diagnostic, that double
13895 constants fit in long double.
13897 2004-06-03 Kevin Ryde <user42@zip.com.au>
13899 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13900 malloc(0) and realloc(NULL,size).
13902 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13905 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13907 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13908 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13911 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13913 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13914 can be rewritten using if-then-else. Suggested by Bruno Haible.
13916 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13918 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13919 Problem reported by Stepan Kasal.
13921 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13923 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13924 change). Patch reported by Ralf Wildenhues in
13925 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13927 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13928 function F exists if the compiler and linker let you compile an
13929 expression like (F != 0). Recent versions of GCC optimize away
13930 the reference to F in that case, since every function address must
13931 be nonzero, so the link succeeds even if F does not exist.
13932 Problem reported by Manu in
13933 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13935 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13936 "Unix". Many uses changed.
13937 (Limitations of Builtins): Explain better why the ! command isn't
13940 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13942 * lib/autom4te.in (Automake-preselections): Preselect
13943 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13945 2004-05-19 Kevin Ryde <user42@zip.com.au>
13947 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13948 referencing AC_FUNC_STRERROR_R.
13950 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13951 note pessimistic assumption when cross compiling.
13953 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13955 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13956 (until 2004) invoked subcommands with sh -e, contra POSIX.
13957 Reported by Kevin Ryde.
13959 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13961 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13962 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13963 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13964 `test -f " /usr/bin/grep"', which _always_ failed.
13965 (AC_PROG_SED): Ditto bogus PATH fix.
13966 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13967 requires that grep correctly supports _multiple_ `-e' options, rather
13968 than stating only that grep should accept `-e'.
13970 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13972 Port to C99, which requires that 'exit' be declared.
13974 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13975 to ensure that stdlib.h is included.
13976 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13977 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13978 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13979 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13980 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13981 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13982 when using 'exit' in a test; C99 requires that 'exit' be declared.
13984 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13986 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13987 now prefers 'grep' implementations that accept -e.
13988 (Limitations of Usual Tools): Describe problems of traditional
13989 egrep and fgrep with long input lines, and of traditional grep
13991 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13992 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13993 All callers changed. Append /usr/xpg4/bin to the PATH, for
13995 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13996 the user with complaints about multiple -e options.
13997 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13998 Define it with AC_PROG_GREP.
13999 * configure.ac (AC_PROG_GREP): Add.
14000 * lib/freeze.mk (GREP): New macro.
14002 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14004 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14005 a possible candidate only after all others fail, rather than
14006 consulting it first. This improves backward compatibility by
14007 better reflecting the way shell selection occurred in previous
14008 versions of Autoconf, and should help to avoid triggering latent
14009 problems in other packages, such as the one in Automake where zsh
14010 is not handled robustly:
14011 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14012 Although it is not Autoconf's responsibility to work around
14013 problems in Automake, it nevertheless makes sense to avoid
14014 introducing unnecessary incompatibilites.
14016 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14017 Gary V. Vaughan <gary@gnu.org>
14019 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14020 how deeply nested we are when a suitable tool is found, set the
14021 ac_path_TOOL_found flag.
14022 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14023 nested we are in this macro. Break out of all 3 nested loops if
14024 ac_path_TOOL_found is set.
14026 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14028 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14029 of the _AS_PATH_WALK loop too if GNU flavor is found.
14031 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14033 * doc/autoconf.texi (Limitations of Make): Update documentation
14034 for `$<'. New entry `Long lines', based on a report from Simon
14035 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14036 paragraph about DJGPP, based on a mail from Richard Dawe.
14038 2004-04-20 Paul Eggert <eggert@twinsun.com>
14040 * tests/c.at (C keywords): Don't assume that GCC supports
14041 "restrict" and "inline", as sufficiently-old GCC versions do not
14042 (also, GCC configured to be in pedantic C89 mode does not).
14043 Problem reported by Sumit Pandya in:
14044 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14046 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14047 consider -g to work if it generates warnings when plain compiles
14048 don't. Problem reported by Braden McDaniel in:
14049 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14051 * doc/autoconf.texi (Slashes): New section, to document a problem
14052 reported by Jim Meyering in:
14053 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14055 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14056 linker output files before linking, to work around IRIX 6 linker bug.
14057 Problem reported by Rainer Orth in:
14058 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14060 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14062 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14063 best tool so far counter rely on the tool path variable name to
14064 avoid checks for one tool being affected by the results of running
14065 the length check on a previous tool.
14067 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14068 match expression argument, as different greps have different
14069 regular expression flavours.
14070 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14072 (AC_PROG_EGREP): Pass 'EGREP$'.
14073 (AC_PROG_GREP): Pass 'GREP$'.
14075 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14077 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14078 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14080 2004-03-29 Paul Eggert <eggert@twinsun.com>
14082 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14083 Types, Specific Compiler Characteristics, System Services,
14084 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14085 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14086 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
14087 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
14089 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
14090 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
14091 AC_TYPE_OFF_T): Likewise.

14098 2004-03-28 Paul Eggert <eggert@twinsun.com>
14100 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14101 now defines HAVE_DECL_TZNAME if it is declared, when
14102 HAVE_STRUCT_TM_TM_ZONE is not defined.
14103 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14104 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14107 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14109 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14110 superfluous backslashing of quotes (") in sed expressions;
14111 thanks to Paul Eggert.
14113 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14115 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14116 Fortran compiler is ifort, also added pghpf; thanks to Nelson
14117 H. F. Beebe for the bug report.
14119 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
14121 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
14122 quoted -cmdline argument in Portland Group compiler (bug
14123 reported by Jeffrey J. Barteet).
14125 2004-03-25 Kevin Ryde <user42@zip.com.au>
14127 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

14132 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
14133 inherits from language Autoconf-without-aclocal-m4.
14134 (Customizing autom4te): Adjust example; the cache must now be
14135 disabled for language Autoconf-without-aclocal-m4.

14151 behavioral changes.
14152 * tests/mktests.sh: Do not generate tests for the
14154 * NEWS: Document these changes.
14156 * doc/autoconf.texi: Avoid macros with unbraced arguments,
14157 they make TeX hang up.
14159 2004-03-15 Paul Eggert <eggert@bogus.example.com>
14161 * NEWS: New macro AC_CHECK_ALIGNOF.
14162 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
14163 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
14164 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
14166 (AC_CHECK_ALIGNOF): New macro.
14167 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
14168 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
14171 2004-03-03 Paul Eggert <eggert@twinsun.com>
14173 * bin/Makefile.am (edit): Don't use $< in a context where
14174 POSIX doesn't require support for it. Use $@.in instead.
14175 Problem reported by Anthony N. Frasso in
14176 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
14177 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
14179 2004-02-23 Gary V. Vaughan <gary@gnu.org>
14181 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
14182 from the next generation of Libtool.

14188 is not always thread-safe. Report from Nathanael Nerode.
14190 2004-02-18 Paul Eggert <eggert@twinsun.com>
14192 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14193 problem on QNX reported by Stephen Rasku in

14196 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
14197 $(m4sh_m4f_dependencies); this removes a FIXME.
14198 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
14199 (MAINTAINERCLEANFILES): Split into pieces,
14200 one per related section. Add $(srcdir)/wrapper.in.
14202 2004-02-09 Paul Eggert <eggert@twinsun.com>
14204 * doc/autoconf.texi (Setting Output Variables): Emphasize that
14205 AC_SUBST provides no portable way to escape literal newlines.
14207 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14208 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14209 Darwin uses -lcrt2.o and there's little point to cataloging all
14210 the system variants. Partial fix reported by Andreas Waechter in:
14211 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

14217 * doc/autoconf.texi (AU_DEFUN): Fix English,
14218 suggested by Paul Eggert.
14219 * lib/autoconf/autoupdate.m4: Correct reference to
14220 acobsolete.m4, suggested by Alexandre Duret-Lutz.
14222 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
14224 * bin/autoupdate.in: Define __file__ so that warnings
14225 refer to the correct file.

14238 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14239 (AS_INIT): Output shell initialization there. Removed optional
14240 parameter. Expand _AS_SHELL_FN_SPY.
14241 (AS_INIT_WITH_SHELL_FN): Removed.
14242 (_AS_SHELL_FN_SPY): New macro.

14249 (_AS_RUN): Move it here, support testing with eval.
14250 (AS_REQUIRE_SHELL_FN): Require shell functions when
14252 (_AS_LINENO_WORKS): Put around braces, we do not
14253 trigger the bash bug anymore.
14254 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14255 use AS_INIT_WITH_SHELL_FN.
14256 * bin/autoconf.in, tests/wrapper.in: Regenerated.

14264 (AU_DEFUN): Honor the third parameter, create autoupdate
14265 macros with AU_DEFINE.
14266 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
14267 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

14286 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
14287 2003 (except 1997) to the list of copyright years. This undoes
14288 the 2003-05-22 change, which removed the older years from the list.
14289 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

14295 grep or ggrep program in PATH that accepts as long lines as
14297 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

14300 egrep and fgrep respectively if $GREP -E/-F don't work.
14301 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14302 _AC_PROG_GREP, and AC_PROG_SED.
14303 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14304 longest input length accepted by a command.
14305 (AC_PROG_SED): Use it.

14309 2004-01-27 Paul Eggert <eggert@twinsun.com>
14311 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
14312 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

14335 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14336 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14337 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14338 not <inttypes.h>. Problem reported by Tim Mooney in
14339 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14340 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14343 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14344 otherwise "make check" fails because it forbids cmp (I guess
14345 because cmp treats files as binary on DOS-like systems).
14347 * tests/mktests.sh: Update copyright date to 2004, since some tests
14348 have changed in 2004.
14350 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14352 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14353 non-truncating sed or gsed program in PATH.
14354 * tests/acprograms.at: Add it.
14355 * doc/autoconf.texi (Particular Programs): Document it.
14358 2004-01-15 Paul Eggert <eggert@twinsun.com>
14360 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14361 -std1 disables some useful extensions on Tru64. Problem reported
14362 by N. Lichtmaier in
14363 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14365 2004-01-14 Paul Eggert <eggert@twinsun.com>
14367 * doc/autoconf.texi (Programming in M4sh): Document that
14368 AS_MKDIR_P succeeds if the destination is a symbolic link
14369 to an existing directory.
14370 (Limitations of Usual Tools): Note that mkdir -p might not
14371 succeed on symlinks to directories.
14373 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14375 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14376 * bin/autoheader.in: Grammar fix in message.
14377 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14378 Test for dir before calling mkdir -p. (trivial changes)
14380 2004-01-13 Eric Blake <ebb9@byu.net>

14385 2004-01-10 Jim Meyering <jim@meyering.net>
14387 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14389 2004-01-09 Paul Eggert <eggert@twinsun.com>
14391 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14392 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14393 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14394 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14395 AC_COMPILE_IFELSE, since we now assume our caller invokes
14396 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14397 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14398 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14399 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14401 2004-01-07 Paul Eggert <eggert@twinsun.com>
14403 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14404 `"'...'"`, as it's confusing (and I suspect it may not work on
14405 some platforms). The code was incorrect anyway, as it assumed
14406 that \$ evaluated to itself in that context. Reported by
14407 Alexandre Duret-Lutz.
14409 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14411 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14412 and _LT_AC_TAGCONFIG.

14439 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14440 Use "rm -f" to remove conftest.sed, not plain "rm".
14441 Bug reported by David Relson in
14442 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14444 * Makefile.am (autom4te-update):
14445 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
14446 * Makefile.maint (my-distcheck, do-po-update): Likewise.

14461 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14462 -c -o might not work. From a suggestion by Kevin Ryde.
14463 (C Compiler, Generating Sources, Limitations
14464 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14465 Don't put '-o' after non-options, as POSIX doesn't allow this.
14466 Mention that cc's name might be gcc or c89 or whatever.
14468 2004-01-04 Kevin Ryde <user42@zip.com.au>
14470 * doc/autoconf.texi: Add various further index entries.

14477 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14479 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14480 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14481 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14482 explanation clearer.
14484 2003-12-24 Andreas Schwab <schwab@suse.de>
14486 * doc/autoconf.texi (Default Includes): Fix misspelling of

14492 * configure: Regenerate.
14493 * tests/atlocal.in: Store the result here.
14494 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14496 of explicitly testing.
14497 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14498 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14499 * tests/tools.at (Syntax of the shell scripts): Simplify
14500 using AT_CHECK_SHELL_SYNTAX.

14569 parameter of AU_DEFUN.

14573 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
14574 the expanded body, consistently with other macros such as AC_USG.
14576 2003-11-17 Paul Eggert <eggert@twinsun.com>
14578 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
14579 into the initial confdefs.h, to work around a bug in NextStep 3.3
14580 patch 3 reported by Eric Sunshine.
14582 2003-11-15 Kevin Ryde <user42@zip.com.au>
14584 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
14585 than $target since the latter is not usual, add guidelines on when to
14586 use or not use the system type.

14590 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

14765 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
14767 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
14768 -mGLOB_options_string stuff for Intel ifc, which can cause

14792 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14793 cache variable instead of $G77 to decide whether to include -O2,
14794 since $G77 is specific to Fortran 77.

14798 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14799 free" flag. Re-order flags tested into rough order of popularity.
14801 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14803 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14804 arguments so that it can be used with syntax identical to
14805 AC_PROG_F77, and so that we can more easily decide to
14806 remove/deprecate the DIALECT optional argument in the future if it
14807 proves troublesome.
14808 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14809 non-freeform-supporting compilers. Document freeform flags.
14811 2003-10-03 Akim Demaille <akim@epita.fr>

14873 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14874 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14875 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

14880 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14881 directory for AC_CONFIG_COMMANDS' first argument exists.
14882 This makes valid the invocation of _AC_SRCPATH that follows.
14883 Reported by Eric Sunshine.

14907 The test suite are sometimes assigning timings incorrectly.
14908 Reported by Henk Krus.
14909 Diagnosed by Nicolas Joly.
14911 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14913 Instead of making AT_help a sequence of assignments to grow
14914 $at_help_all, just make AT_help_all be the growing contents of
14915 $at_help_all, and make a single assignment in...
14917 (at_times_skip): Flip the meaning and rename as...
14918 (at_times_p): this.

14929 (ifnames): chmod -w.
14930 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14931 executables, not bin/ executables! Otherwise all the magic needed
14932 to find non installed files is turned off. This caused a failure
14933 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14934 as found in its environment (sent by tests/autoreconf): pointing
14935 to bin/autom4te that could not find its files.
14936 * tests/mktests.sh: Force the replacement of generated files, for
14937 the sake of "mv" program that are interactive when overwriting a

15032 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15034 Add support for newer Fortran dialects. The F77 interface is
15035 unchanged, and continues to support Fortran 77. New FC macros
15036 correspond to all the old F77 macros, with output variables FC,
15037 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15038 available dialect, but older dialects can be specified. There are
15039 new macros AC_FC_SRCEXT to set the source extension, and
15040 AC_FC_FREEFORM to accept free-form source files.
15042 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15079 are defaulted by AT_CHECK anyway.
15080 Use AT_CHECK_AUTOM4TE.

15164 * lib/Autom4te/General.pm: Don't export error: you don't own it.
15166 2003-08-21 Akim Demaille <akim@epita.fr>
15168 First stab at preserving warnings between calls to autom4te,
15169 including when the cache is used.
15171 There are still several issues: (i) there are too many runs of m4
15172 (one for include, one for warnings, and some more), (ii) warnings
15173 spreading on several lines are not handled gracefully, (iii) the
15174 code meant to have the call stack display for errors does not work
15175 (its handling should move from m4 to autom4te).
15177 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15179 (@preselect): Add m4_warn.
15180 ($exit_status): Remove, use $exit_code.
15181 ($help): Use Autom4te::ChannelDefs::usage.
15182 (&handle_m4): No longer define the m4_warnings.
15183 At each run, extract and report the warnings.
15184 Always cache the result, including if the exit status is on
15185 failure, since if nothing changes, we should result in the same
15186 failure, hence we can use the cache.
15187 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15188 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15190 (m4_warn): Redefine as a do-nothing: it is its invocation that
15191 matters, as warnings are now reported via traces.
15192 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15193 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15194 the latter reveals calls to the former.
15198 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15200 2003-08-21 Akim Demaille <akim@epita.fr>
15202 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

15211 (&usage): Return a string, not a side effect.
15212 (cross): New warning category.

15232 * bin/autom4te: Adjust.
15233 In particular, be Autoconf tools are really silent when properly
15234 working, bind the verbosity of the 'note' channel to $verbose.
15235 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15236 (&xsystem, &contents): Remove, since they are exported by...
15237 * lib/Autom4te/FileUtils.pm: this.
15239 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
15240 * lib/Autom4te/FileUtils.pm: here.
15242 2003-08-20 Akim Demaille <akim@epita.fr>
15244 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

15355 From Gareth McCaughan.
15357 2003-06-23 Akim Demaille <akim@epita.fr>
15359 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15360 not all of them. This fixes 1. the fact that when testing
15361 Autoconf there are many many config.log, 2. the incorrect use of
15362 top_srcdir to find config.log.
15363 Don't mix the detailed output of failed test with the summary of
15364 failures. Rather, append detailed log afterwards.
15366 2003-06-23 Akim Demaille <akim@epita.fr>
15368 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
15369 always run: output config.log on $at_group_log.

15448 altered by WEXITSTATUS.
15449 (xqx, xsystem): Use handle_exec_errors.
15451 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
15453 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
15454 Do not call `_exit()', simply modify `$?'.
15455 (xsystem): Reset $! before running system, and check it afterward.
15456 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
15457 63 for version mismatches.
15459 2003-05-23 Akim Demaille <akim@epita.fr>
15461 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
15462 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
15463 the middle of a line).

15471 difference with a plain failure.

15481 Paul Eggert <eggert@twinsun.com>
15483 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15484 Remove `#include <stdlib.h>' from the list; we should never
15485 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15486 resulting namespace pollution would cause other tests to fail.
15487 Configure scripts run with some older versions of g++ and HP's
15488 aCC would fail due to such an #include. Problems reported by
15489 Matthew Mueller in <http://bugs.debian.org/120704> and by
15491 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15492 In the test, use the test declaration before including <stdlib.h>,
15493 as that's closer to how it'll be used.

15497 * doc/autoconf.texi (Header Portability): ucred.h.
15500 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15502 Overhaul Autotest's logging: generate separate log files
15503 in testsuite.dir/NNN/testsuite.log, and append them to
15504 testsuite.log instead of re-running the test verbosely.
15506 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15507 file descriptor, write 0 to at_status_file instead of setting
15508 at_status=0, initialize some new variables (at_status_file,
15509 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15510 to rerun the tests, instead append the at_group_log to the
15511 at_suite_log when a test fails.
15512 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15513 with the AS_MESSAGE_LOG_FD redirected to stdout.
15514 (AT_CLEANUP): save the output status in $at_status_file
15515 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15516 its original place.
15517 (AT_CHECK): since tests are run with a redirected stdout,
15518 and used to be re-run in verbose mode, turn some $at_verbose
15519 into echo, and don't redirect the output of testing stdout
15522 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15523 the name of the debugging directory and information about

15647 by aclocal.m4 is changed it might require the importing of another
15648 m4 extension file, i.e., aclocal must be run.
15650 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15651 (&parse_args): Use --force with aclocal if required and supported.
15652 (&autoreconf_current_directory): Use &run_aclocal.

15656 Lock autom4te's cache.
15658 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
15659 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
15660 argument instead of a file name, so that the request file remains
15661 open during the whole autom4te run.
15662 ($icache_file): New.
15663 (&freeze): Lock the $icache_file.
15665 2003-04-29 Derek Price <derek@ximbiot.com>
15667 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15668 seperator with m4_append_uniq(). It doesn't work.
15669 (AT_CLEANUP): Add `;' to end of at_help_all.
15670 (AT_INIT): Allow --keywords to be specified more than once. When
15671 grepping $at_help_all for keywords, use the field and keyword
15672 seperators to ensure a complete keyword match. Alter at_prev handling
15673 to support the new --keywords behavior.
15675 2003-04-27 Karl Berry <karl@freefriends.org>
15677 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15678 align better with others. I also made some of the individual
15679 entries on one line, for brevity and to make it easier for me to
15680 sort my dir-example file in the Texinfo distribution :).
15682 2003-04-12 Jim Meyering <jim@meyering.net>

15745 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
15746 reading the section "Present But Cannot Be Compiled" when the
15747 header causes problems.
15749 2003-03-28 Akim Demaille <akim@epita.fr>
15751 * tests/torture.at (Configuring subdirectories): Require aclocal
15752 1.4, otherwise the test fails, as it does support configure.ac.
15753 This fixes the "test 40 failed" bug reports.
15755 2003-03-28 Akim Demaille <akim@epita.fr>
15757 * doc/autoconf.texi (C Compiler): `#line' portability.

15775 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
15776 obsolete AC_HELP_STRING.
15777 (AC_HELP_STRING): AU_DEFUN to...
15778 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
15779 * tests/m4sh.at (AS_HELP_STRING): New test.
15781 * tests/acgeneral.at: Regenerated.
15783 2003-03-26 Derek Price <derek@ximbiot.com>
15785 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
15786 sense. Verbosify the diversion definitions comment.

15811 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): Normalize
15812 file name for the m4 program, when it has an "exe" file extension.
15813 DJGPP's error messages include the error code in brackets -

15823 about `$<' in inference rules, it was a bogus interpretation of
15824 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
15825 Tru64 make in the "target lookup" section.
15826 (Automake): Automake 1.5+ no longer requires special tools to be
15827 present on the developer's host.
15829 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
15831 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
15832 to a shell that can handle redirection or quoting correctly.
15833 Override SHELL with the shell detected by configure.
15834 Use of $^O suggested by Tim van Holder.
15835 * bin/autom4te.in (BEGIN): Likewise.
15836 * bin/autoreconf.in (BEGIN): Likewise.
15837 * bin/autoscan.in (BEGIN): Likewise.
15838 * bin/autoupdate.in (BEGIN): Likewise.
15839 * bin/ifnames.in (BEGIN): Likewise.
15841 * bin/ifnames.in: Add final newline to help and version messages.
15843 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15844 to cope with DOS-style absolute paths, when constructing
15847 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15848 When constructing paths with IFS=:, quote the path. If we're
15849 constructing a DOS-style absolute path, we don't want to split it
15852 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
15855 2003-02-25 Pavel Roskin <proski@gnu.org>
15857 * bin/autoheader.in: Add missing newline when printing

15863 2002-09-01 patch by replacing "test -n" with "test -z".
15864 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
15865 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
15867 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
15868 to fix a mismatch between example and discussion.
15870 2003-02-24 Kevin Ryde <user42@zip.com.au>
15872 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
15873 format starting with "-".
15875 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15877 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15878 is not portable inside Makefile.
15880 2003-02-20 Akim Demaille <akim@epita.fr>
15882 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15883 compiler says yeah, but preproc says nope, compiler is right.
15884 Conversely, prompt the reader to send a bug report to the
15885 maintainers of the package, not of Autoconf.
15887 2003-02-20 Klee Dienes <kdienes@apple.com>
15889 * bin/autoreconf.in (autoreconf_current_directory): Properly
15890 handle an empty aclocal.m4.

15895 $ac_prefix_program.
15898 2002-12-23 Paul Eggert <eggert@twinsun.com>
15900 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15901 innocuous variant befor including <limits.h> or <assert.h>. This
15902 works around a bug reported by Albert Chin: HP-UX 11i
15903 (and earlier versions) have a <limits.h> that declares
15904 gettimeofday and many other functions.
15906 2002-12-03 Paul Eggert <eggert@twinsun.com>
15910 * NEWS, configure.ac: Update version.
15912 * doc/fdl.texi: Upgrade to FDL version 1.2.
15914 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15915 nontrivially in main's body, so that f's external declaration is
15916 not optimized away in AIX. This should fix the bug reported by
15918 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15920 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15921 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15922 defined, to support freestanding compilers. This should fix the
15923 bug reported by Momchil Velkov in
15924 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15926 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15927 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
15928 obsolete AC_CHECK_TYPE. The missing empty arg was reported

15930 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
15932 * Makefile.maint (www-gnu): New macro.
15933 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
15934 the location has moved.
15936 2002-12-02 Martin Frydl <martin@systinet.com>
15938 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15939 \(.*\) match is too long and there is something more to be checked.
15940 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
15942 2002-11-15 Akim Demaille <akim@epita.fr>

15958 Update from masters.
15960 2002-11-14 Akim Demaille <akim@epita.fr>
15962 * Makefile.maint: Sync with Bison, i.e.:
15963 (po-check): Scan .l and .y files instead of the
15964 .c and the .h files that they generate. This fixes the bug
15965 reported by Tim Van Holder in:
15966 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15967 Look for N_ as well as for _. Try to avoid matching #define for
15971 2002-11-14 Akim Demaille <akim@epita.fr>
15973 * doc/autoconf.texi (C Compiler): Compiling several files at once.
15974 From Paul Eggert and Albert Chin-A-Young.
15976 2002-11-14 Akim Demaille <akim@epita.fr>
15978 * doc/autoconf.texi (C Compiler): Solitary backslashes.
15979 From Paul Eggert and Albert Chin-A-Young.
15981 2002-11-14 Kevin Ryde <user42@zip.com.au>
15983 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15984 than assigning in main, to avoid HP cc +O3 optimizing it away.
15986 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15988 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15989 option. Process --recheck after parsing all options. Pass -q
15990 option to configure on --recheck.
15991 (AC_OUTPUT): Pass -q from configure to config.status.
15992 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15993 arguments to record.
15994 * doc/autoconf.texi (config.status Invocation): Document
15995 config.status -q option.
15997 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15999 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16000 Makefile.in if Makefile.am exists.
16001 (output): Strip `.am' from Makefiles. Don't
16002 output AC_CONFIG_FILES if no Makefiles were found.
16004 2002-11-07 Akim Demaille <akim@epita.fr>
16006 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
16007 (local_updates): New.

16009 (local_updates): New.
16011 2002-11-06 Akim Demaille <akim@epita.fr>
16013 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
16014 declaration in extern "C" too.

16022 Reported by Ezra Peisach.
16024 2002-11-05 Akim Demaille <akim@epita.fr>
16026 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16028 We _have_ to stop using the old compatibility scheme that tried to
16029 avoid useless backslashes because Libtool 1.4.3 contains a
16030 AC_DEFINE([error_t], [int],
16031 [Define to a type to use for \`error_t' if it is not
16032 otherwise available.])
16033 We _have_ to quote the single quote and backslashes with \. The
16034 old compatibility scheme saw that ` was backslashed, and therefore
16035 did not quote the single quote. Hence before this patch, Autoconf
16036 was not compatible with Libtool.
16038 2002-11-04 Paul Eggert <eggert@twinsun.com>
16040 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16057 (&autoreconf): here.
16058 ($help, $make, &parse_args, &autoreconf_current_directory):
16060 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16062 2002-10-31 Bruno Haible <bruno@clisp.org>

16076 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
16078 2002-10-31 Akim Demaille <akim@epita.fr>
16080 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16081 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16082 Make variable, not a shell variable.
16083 Suggested by Bruno Haible.
16085 2002-10-31 Akim Demaille <akim@epita.fr>
16087 * bin/autom4te.in (load_configuration): Reject #args out of any
16090 2002-10-31 Akim Demaille <akim@epita.fr>
16092 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
16093 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
16094 (_AC_RUN_IFELSE): Use it.
16095 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

16103 * doc/autoconf.texi (autom4te Invocation): Adjust.
16104 Suggested by Tim van Holder.
16106 2002-10-29 Paul Eggert <eggert@twinsun.com>
16108 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
16109 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
16110 Problem reported by Bruno Haible.
16112 2002-10-29 Akim Demaille <akim@epita.fr>
16114 * doc/autoconf.texi (Header Templates): Put also in words what the
16115 pictures says to assist free style readers.
16116 (Customizing autom4te): s/--cache=/--cache /.
16118 2002-10-29 Akim Demaille <akim@epita.fr>
16120 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
16122 sparc_address_test returns void.
16123 Use it with an argument, as prototyped.
16126 2002-10-29 Akim Demaille <akim@epita.fr>
16128 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

16427 Reported by Alexandre Duret-Lutz.
16429 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16490 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16491 aclocal invocation, as Gettext macros might not be visible to

16494 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16495 Reported by Paul D. Smith.
16497 2002-10-08 Paul Eggert <eggert@twinsun.com>

16527 * tests/torture.at (Configuring subdirectories): Be robust to

16632 * bin/autoscan.in: Improve the comments.
16633 (&parse_args): Drop obsolete undocumented options.
16634 (&output_kind): Output warnings.
16635 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

16641 Reported by Ralf Corsepius.
16642 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16644 2002-09-26 Akim Demaille <akim@epita.fr>
16646 Single suffix rules and seperated dependencies are not portable.
16648 * doc/autoconf.texi (Installation Directory Variables): Update.
16649 (Limitations of Make): Some about `Single Suffix Rules and
16650 Separated Dependencies'.
16651 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16652 (ifnames, autoscan, autom4te): Un-factor into several rules.
16654 2002-09-25 Paul Eggert <eggert@twinsun.com>
16656 * BUGS (Interoperability bugs): New section. Mention libtool
16657 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16659 2002-09-24 Paul Eggert <eggert@twinsun.com>
16661 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16662 make handles suffix-rules differently from GNU make.
16664 * bin/Makefile.am (SUFFIXES, .in): Remove.
16665 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16666 Move the body of the old .in rule here.
16668 2002-09-16 Akim Demaille <akim@epita.fr>
16670 i960 compilers create `b.out' files by default.
16671 Reported by Ralf Corsepius.
16673 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16674 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16676 2002-09-13 Paul Eggert <eggert@twinsun.com>
16678 * doc/autoconf.texi (Particular Headers): Remove obsolete
16679 reference to `struct timezone' in the description of

16687 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16688 * Makefile.am: Adjust.
16690 2002-09-13 Akim Demaille <akim@epita.fr>
16692 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16693 reading config.log when the compiler is rejected.
16694 Suggested by Guido Draheim.
16696 2002-09-13 Akim Demaille <akim@epita.fr>
16698 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16699 (chdir_init) might hang when stat'ing mounted directories.
16700 Reported by Vance Shipley.
16702 2002-09-12 Akim Demaille <akim@epita.fr>
16704 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16707 2002-09-12 Akim Demaille <akim@epita.fr>
16709 * doc/autoconf.texi (Defining Symbols): Present two different
16710 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16711 difference between 1 argument calls, and 2-3 argument calls.
16713 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16715 * doc/autoconf.texi: Review grammar and punctuation.
16717 2002-09-11 Paul Eggert <eggert@twinsun.com>
16719 * doc/autoconf.texi: Fix minor formatting, spelling, and
16721 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16722 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16725 2002-09-11 Akim Demaille <akim@epita.fr>
16727 * doc/autoconf.texi (Questions): Rename as...
16729 (Defining Directories): New.
16731 2002-09-09 Akim Demaille <akim@epita.fr>
16733 * doc/autoconf.texi (Making testsuite Scripts): Update.
16734 Suggested by Nishio Futoshi.
16736 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16738 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16739 plain `@' is wanted.
16741 2002-09-09 Akim Demaille <akim@epita.fr>
16743 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16744 `duplicates', since the algorithm was too naive and could keep
16745 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16746 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16747 Reported by Ralf Corsepius.
16748 * tests/torture.at (Configuring subdirectories): Exercise these
16751 2002-09-09 Akim Demaille <akim@epita.fr>
16753 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16754 looking for a replacement file.
16755 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16756 directory is relative.
16757 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16758 directory definition.
16759 Reported by Andreas Schwab and Jim Meyering.
16761 2002-09-06 Akim Demaille <akim@epita.fr>
16763 * doc/autoconf.texi (Setting Output Variables): Clarify what
16764 precious variables are.
16765 Suggested by Pontus Skoeld.
16767 2002-09-05 Akim Demaille <akim@epita.fr>
16769 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16770 (ifnames, autoscan, autom4te): Since we don't only depend on
16771 configure.ac variables (such as VERSION etc.), but also on prefix
16772 and so forth, depend on Makefile, not configure.ac.
16773 Reported by Alexandre Duret-Lutz.
16774 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16776 2002-09-05 Kevin Ryde <user42@zip.com.au>
16778 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16779 doesn't seem to be confined to ia64, just say "some versions".
16781 2002-09-04 Akim Demaille <akim@epita.fr>
16783 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16785 * Makefile.am (maintainer-clean-local): Remove.
16786 (MAINTAINERCLEANFILES): Remove COPYING.
16788 2002-09-03 Paul Eggert <eggert@twinsun.com>
16790 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16791 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16794 2002-09-03 Akim Demaille <akim@epita.fr>
16796 * configure.ac: Bump to 2.53d.
16797 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16798 as of today, on Automake's team suggestion.
16800 2002-09-03 Akim Demaille <akim@epita.fr>
16804 2002-09-02 Akim Demaille <akim@epita.fr>
16806 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16808 * configure.ac: Disable SITE_MACRO_DIR.
16810 2002-09-02 Jim Meyering <meyering@lucent.com>
16812 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16813 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16814 Also, tweak grammar: s/make sure to/be sure to/.
16816 2002-09-02 Paul Eggert <eggert@twinsun.com>
16818 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16819 directory names are generally preferable to physical names.
16821 2002-09-02 Akim Demaille <akim@epita.fr>
16823 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16824 Reported by Raja R. Harinath.
16825 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16826 * bin/autoupdate.in: Use error instead of die.
16828 2002-09-01 Paul Eggert <eggert@twinsun.com>
16830 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16831 ordinary shell concatenation rather than echo+tr+sed command that
16832 runs afoul of a long-line-related sed bug in Solaris 8.
16834 * bin/autoheader.in (parse_args): --warning -> --warnings.
16836 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16837 stdout, as traditional "ls" does.
16838 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16839 _AC_COMPILER_EXEEXT_O): Likewise.
16840 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16842 * bin/autoconf.as: Add --prepend-include option. This patch was
16843 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16844 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16846 * bin/autoconf.in, configure: Regenerate.
16848 * doc/autoconf.texi (Special Shell Variables): Mention
16849 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16851 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16852 MAILPATH and set PS1, PS2, PS4 to default values, to work
16853 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16854 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16855 the Autoconf documentation specifies; fall back to "unset" only if
16856 this fails. Use a shell for-loop for this rather than an m4 loop,
16857 to shorten the output script.
16859 2002-08-30 Paul Eggert <eggert@twinsun.com>
16861 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16862 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16863 for the CDPATH problem. Document PWD.
16864 (Limitations of Builtins): Document the problem that "cd $foo" and
16865 "ls $foo" may refer to different directories in shells conforming
16866 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16867 example, since the old example is now out of date.
16869 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16870 FOO" and "ls FOO" talk about different directories; this catches
16871 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16874 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16875 of rolling our own unset.
16876 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16877 in practice we needn't worry about CDPATH if unset doesn't work.
16879 * Makefile.in, aclocal.m4, bin/Makefile.in,
16880 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16881 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16882 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16883 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16884 tests/Makefile.in: Regenerate with Automake 1.6.3.
16886 * config/config.guess, config/config.sub, config/mkinstalldirs:
16889 * configure: Regenerate with self.
16891 2002-08-30 Kevin Ryde <user42@zip.com.au>

16901 2002-08-29 Akim Demaille <akim@epita.fr>
16903 * lib/Autom4te/General.pm (&xqx): New.
16904 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16905 hand, which is not portable.
16907 * bin/autom4te.in: Use them.
16908 Use &error instead of die.
16909 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16912 2002-08-17 Paul Eggert <eggert@twinsun.com>
16914 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16915 default list of compilers to try, since it was long ago superseded
16916 by the ksh fc builtin. Suggested by Steven G. Johnson.
16918 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16920 * doc/autoconf.texi (Invoking autom4te): End the option table,
16921 fixing a bug introduced by the previous patch.
16922 (Limitations of Make): Add a 'target lookup' subentry in the
16923 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16925 2002-07-29 Mark D. Roth <roth@feep.net>
16927 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16928 options and use $AUTOM4TE_PATH.
16929 * doc/autoconf.texi: Remove documentation of autom4te
16930 --include-envvar and --site-macro-subdir options and document
16931 use of $AUTOM4TE_PATH.
16932 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16933 arguments from each language section.
16935 2002-07-29 Paul Eggert <eggert@twinsun.com>
16937 * doc/install.texi: Include copyright symbol in copyright notice.
16939 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16941 (AM_MAKEINFOFLAGS): New macro.
16942 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16943 * Makefile.am (INSTALL): Use the new macros.
16944 Use -o rather than --output, since "missing" does not grok --output.
16946 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16948 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16949 comments do not always work. Never trust the exit status of
16952 2002-07-24 Kevin Ryde <user42@zip.com.au>
16954 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16955 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16957 2002-07-23 Paul Eggert <eggert@twinsun.com>
16959 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16960 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16961 apparently treats PATH="nonexistent" as if it contained ".".
16962 Bug reported by Stefan `Sec' Zehl.
16964 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16966 * doc/autoconf.texi (Limitations of Make): Mention the special
16967 handling of the obj/ directory by BSD make.

17013 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
17014 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17015 latter was not run.
17017 2002-07-17 Akim Demaille <akim@epita.fr>
17019 * lib/Autom4te/General.pm (find_file): Browse the directories in
17020 the order they are given.

17232 This improves on an earlier suggestion by H. Peter Anvin.
17234 2002-05-16 Paul Eggert <eggert@twinsun.com>
17236 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17237 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17238 Both macros now accept an optional source-dir arg.
17239 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17241 * NEWS: Document this.
17242 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17244 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17245 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17246 not for GNU extensions; this undoes part of the 2000-11-03 change,
17247 reverting to 2.13-compatible behavior.

17255 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17256 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17257 and it causes a 'test' syntax error if it fails.
17258 Bug reported by Stephen Gildea.
17260 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17261 If prototypes are supported, use them to check this at compile-time,
17262 instead of trying to check it at run-time. If we must do a run-time
17263 check, assume that setvbuf is standard when cross-compiling, as
17264 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17265 Bug reported by Paul D. Smith.
17267 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17268 argument specifying location of getloadavg.c. This removes a
17269 FIXME. This idea was taken from Jim Meyering's implementation in
17271 * doc/autoconf.texi (Particular Functions): Document this.
17272 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17273 that's what the code does; this fixes a bug reported by

17278 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17279 autopoint instead of gettextize.
17280 ($uses_alocal): Rename as...
17281 ($uses_aclocal): this.
17282 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17283 Suggested by Bruno Haible.

17287 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17289 2002-04-29 Paul Eggert <eggert@twinsun.com>
17291 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17292 files to be 1 second older; just set them to be the same time.
17293 Also, sleep 1 second after the first aclocal, to work around
17294 problems with sub-second time stamps on the input files.
17296 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17298 * doc/autoconf.texi: Mention "set -e -x" lossage

17305 From Christian Cornelssen.
17307 2002-04-29 Akim Demaille <akim@epita.fr>
17309 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17310 of lack of $LINENO support, then the test will compare the $LINENO
17311 in testsuite vs. the lineno in the test file. This is wrong, of
17313 Be sure to protect it.
17314 Reported by Patrick Welche.
17316 2002-04-25 Akim Demaille <akim@epita.fr>
17318 * doc/autoconf.texi (Obsolete Macros): Typo.
17319 Reported by Vladimir Volovich.
17321 2002-04-25 Akim Demaille <akim@epita.fr>
17323 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17324 than some of the input files, hence, on the second run of aclocal,
17325 if some of its input are younger, make them older.
17326 Suggested by Paul Eggert.
17328 2002-04-25 Akim Demaille <akim@epita.fr>
17330 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17339 (_AC_INIT_PREPARE): Use them to log them.
17340 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17341 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17342 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17343 _AC_SUBST_FILES and _AC_SUBST_VARS.
17344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17346 2002-04-24 Akim Demaille <akim@epita.fr>
17348 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17349 autoheader, so that automake does not complain about a missing
17350 config.h.in that was to be created.
17352 2002-04-23 Akim Demaille <akim@epita.fr>

17604 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
17607 2002-03-19 Akim Demaille <akim@epita.fr>
17609 * bin/autoscan.in (scan_file): Specify the location in `&used'
17613 2002-03-19 Akim Demaille <akim@epita.fr>
17615 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
17616 From Nishio Futoshi.
17618 2002-03-19 Akim Demaille <akim@epita.fr>
17620 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
17622 2002-03-18 Paul Eggert <eggert@twinsun.com>
17624 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17625 (Limitations of Usual Tools): Add mkdir section.
17627 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17628 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17629 back on AS_DIRNAME to compute prefixes otherwise; this is
17630 roughly what mkinstalldirs does. That way, we need not have
17631 our own filename disassembler. The old disassembler did not
17632 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17634 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17635 Create at_test_all by a series of assignments,
17636 not by a single assignment of a long string. The latter causes ksh
17637 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17638 presumably because of a buffer overrun.
17640 2002-03-14 Paul Eggert <eggert@twinsun.com>
17642 * lib/autotest/general.m4 (at_times_skip):
17643 Renamed from at_times. Now a boolean.
17644 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17645 says 'times: not found'.
17647 2002-03-14 Akim Demaille <akim@epita.fr>
17649 * bin/autoreconf.in (&study_gettextize): New.
17650 (&autoreconf): Handle newest gettextize.

17688 2002-03-08 Akim Demaille <akim@epita.fr>
17690 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17692 2002-03-08 Akim Demaille <akim@epita.fr>
17694 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17695 aliases the actual variables, and modifications of the former
17698 2002-03-08 Akim Demaille <akim@epita.fr>
17700 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17701 because of C-c: have m4 output in tmp files, then mv them.

17724 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17725 * lib/autoconf/general.m4 (AC_INIT): More informative error
17726 message for LIBOBJ.
17728 2002-03-04 Akim Demaille <akim@epita.fr>

17733 2002-03-04 Akim Demaille <akim@epita.fr>
17735 * doc/autoconf.texi (Transforming Names): Equality between target
17736 and host is irrelevant.
17737 (Specifying Names, Canonicalizing): Remove all references to the
17738 backward compatibility hooks. Rather, collect them all into...
17739 (Hosts and Cross-Compilation): this new section.
17740 * doc/install.texi (System Type): Ditto.
17741 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17742 that `--host' implies cross-compilation.
17744 2002-03-04 Akim Demaille <akim@epita.fr>
17746 * doc/autoconf.texi (Evaluation Macros): New.
17747 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17749 (_m4_foreach): Define the variant with immediate evaluation so
17750 that it contains exactly the items, not an expression which
17751 evaluation is the current item.
17752 (m4_re_string, m4_re_word): Don't over quote them.
17754 2002-03-04 Akim Demaille <akim@epita.fr>
17756 Instead of having stacking `shift's evaluated at the end, let
17757 `foreach' loops immediately evaluate them.
17759 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17760 $*. This is the n-th time I change my mind, but hopefully this is
17763 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17765 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17766 it was only a hack for m4_text_wrap.
17767 (m4_car2): Remove, replaced by...
17769 (_m4_foreach): Adjust.
17770 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17771 m4_bpatsubst for clarification.

17822 Fix Autoconf PR/207:
17823 AC_PREFIX_PROGRAM fails with dashed program names
17825 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17826 variable when looking for the prefix program.

17862 2002-02-05 Akim Demaille <akim@epita.fr>
17864 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17886 * bin/autom4te.in (&parse_args): Implement `frozen files are
17887 optional are the sum of the previous files on the command line'.
17888 Also, pass `--reload-state=' on them, so...
17889 (handle_m4): don't.

17891 (M4sh): Rely on M4sugar.

17929 2002-01-28 Akim Demaille <akim@epita.fr>
17931 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17932 AUTOTEST_PATH *after* it was set.
17933 Don't put `.' in the PATH: the user should be precise and `./' if
17934 needed. In addition, given that the test suite does some `cd', if
17935 `.' is in the path, the `tested programs' sections will report
17936 programs found in the test suite's directory, while during the
17937 tests (performed in their own directory), these programs are no
17938 longer visible. In other words, the results is confusing and
17940 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17986 * bin/autom4te.in (parse_args): Don't use
17987 Autoconf::General::getopt with non valid options.

17991 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

18009 * tests/Makefile.am (package.m4): New.
18010 EXTRA_DIST it since its a source.
18012 2002-01-06 Akim Demaille <akim@epita.fr>

18015 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18016 and PACKAGE_BUGREPORT from here...
18017 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18019 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18020 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18021 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18022 * tests/tools.at (autoheader): Adjust.

18044 2001-12-14 Akim Demaille <akim@epita.fr>
18046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18047 trailing files, don't apply `-rf' to files which might not be
18048 created by configure (core, core.*, and *.core), but just `rm -f'.
18049 Suggested by Jonathan Kamens.
18051 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

18090 variables, they are really part of the tokens.
18091 Split the input line on spaces and then look for tokens.
18092 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18093 because of `lex$U.$(OBJEXT)'.

18119 2001-11-26 Akim Demaille <akim@epita.fr>
18121 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18122 Before, having a line containing the opening of a multi line
18123 comment made the whole line be ignored.
18125 2001-11-26 Akim Demaille <akim@epita.fr>
18127 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18128 (testsuite Scripts): Be one of its subsection.
18129 (Autotest Logs): New.
18131 2001-11-26 Akim Demaille <akim@epita.fr>
18133 Test groups are now run two directories deeper.
18135 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18136 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18138 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18139 top_srcdir, builddir and top_builddir.
18140 Use `at_*dir' relatively to the directory containing the
18141 suite, use `*dir' when relatively to the current group dir.
18143 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18145 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18146 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18147 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18150 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18152 * doc/autoconf.texi (Using System Type): Add an example of `case
18153 $host' usage so people quit using `case $target' everywhere.
18155 2001-11-22 Akim Demaille <akim@epita.fr>
18157 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18158 spotted by Jim Meyering.
18160 2001-11-16 Paul Eggert <eggert@twinsun.com>
18162 This patch implements a `long double' suggestion by Oliver Kiddle.
18164 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18165 static, to catch errors if the value isn't known at compile-time
18166 and the compiler supports dynamic arrays. Change its name from
18167 `_array_' to `test_array' to avoid potential name clashes.
18168 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18169 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18170 better than double. Catch a bug in GCC 2.95.2 x86.
18171 * doc/autoconf.texi (C Compiler): Document the above.
18174 2001-11-13 Akim Demaille <akim@epita.fr>
18176 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18178 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18180 2001-11-13 Akim Demaille <akim@epita.fr>
18182 * lib/autotest/general.m4 (AT_INIT): After having run the test
18183 group, go back to the initial directory, not to at_suite_dir.
18185 2001-11-13 Akim Demaille <akim@epita.fr>
18187 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18188 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18189 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18191 (AT_CHECK_CONFIGURE): Use absolute paths.
18192 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18193 The problem is still the old one: there is no means in M4 (that I
18194 know about) to create a defining macro, because there is no means
18195 to create `$1' etc., therefore, the defining macro ``swallows''
18196 all the arguments meant to the defined macro.
18198 2001-11-13 Akim Demaille <akim@epita.fr>
18200 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18201 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18203 * tests/aclocal.m4: Remove, as it is no longer used.
18205 2001-11-13 Akim Demaille <akim@epita.fr>
18207 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18208 variable names when referring to a single test group, or to
18209 `suite' when referring to the whole test suite.
18210 `at_last_test' is removed: m4 compute at_format itself.
18211 (at_stdout, at_stder1, at_stderr): New variables.
18212 (AT_CHECK): Use them.
18214 2001-11-13 Akim Demaille <akim@epita.fr>
18216 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18218 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18219 Do it as soon as a test fails, don't wait till the end of the test
18221 Don't remove $as_me.[0-9]*, since these files no longer exist.
18223 2001-11-13 Akim Demaille <akim@epita.fr>
18225 * tests/tools.at: Use absolute paths, since we are no longer run
18228 2001-11-13 Akim Demaille <akim@epita.fr>
18230 Now that tests are running in their own private dir, there is no
18231 need to list the files to remove at the end of tests groups.
18233 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18234 (AT_data_files, at_data_files): Remove.
18235 (AT_CLEANUP, AT_DATA): Simplify.
18237 Remove the group dir if !debug && !failed.
18238 * tests/atspecific.m4: Adjust.
18240 2001-11-13 Akim Demaille <akim@epita.fr>
18242 Start a new layout for Autotest: `testsuite' creates
18243 `testsuite.dir' in which the at-check-line etc. files are to be
18244 found, and `testsuite.dir/003' where the test group 3 is run.
18246 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18247 at_check_line_file, at_format, at_test_normalized, at_group_dir
18249 Create the directories.
18250 Use absolute paths for at- files.
18251 (AT_CHECK): Adjust.
18253 2001-11-11 Michael Matz <matz@kde.org>
18255 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18257 (m4_car): Properly quote arguments.
18259 2001-11-13 Akim Demaille <akim@epita.fr>
18261 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18262 with stricter rules on LIBOBJS.
18264 2001-11-12 Paul Eggert <eggert@twinsun.com>
18266 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18267 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18270 2001-11-12 Akim Demaille <akim@epita.fr>
18272 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18274 2001-11-12 Akim Demaille <akim@epita.fr>
18276 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18277 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18278 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18279 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18280 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18281 specify to what the macro should be defined (typically to 1).
18283 2001-11-12 Akim Demaille <akim@epita.fr>
18285 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18288 2001-11-12 Akim Demaille <akim@epita.fr>
18290 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18291 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18292 definition used by Automake where LEX is +/- "${missing} lex" and
18293 `missing' itself contains variables.
18295 2001-11-12 Akim Demaille <akim@epita.fr>
18297 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18298 Now that M4sh pushes BODY, the comments were output at the end of
18301 2001-11-08 Akim Demaille <akim@epita.fr>
18303 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18304 that we can trace macros from aclocal.m4.
18305 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18306 obsoleted, and redirect to the former anyway.
18307 Reported by Ralf Corsepius.
18309 2001-11-08 Akim Demaille <akim@epita.fr>
18311 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18312 processed only if present.
18313 * tests/torture.at (Configuring subdirectories): Use autoreconf
18314 instead of successive calls to autoconf.
18315 Add a nonexistent subdirectory to exercise the patch above.
18316 Reported by Ralf Corsepius.
18318 2001-11-08 Kevin Ryde <user42@zip.com.au>
18320 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18321 doesn't accept .S files.
18323 2001-11-07 Akim Demaille <akim@epita.fr>
18325 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18326 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18327 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18328 * bin/autom4te.in (warn_forbidden): New.
18329 (handle_output): Use it.
18330 Read m4_pattern_forbid with messages.
18332 2001-11-05 Akim Demaille <akim@epita.fr>
18334 * bin/autom4te.in (--normalize): Remove.
18335 * lib/autom4te.in: Adjust.
18337 2001-11-05 Akim Demaille <akim@epita.fr>
18339 * tests/Makefile.am (testsuite): Rename this target as...
18340 ($(TESTSUITE)): this.
18343 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18345 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18346 the --prefix option, also remove it's argument.
18348 2001-11-05 Akim Demaille <akim@epita.fr>
18350 * doc/autoconf.texi (testsuite Invocation): Update.
18351 (Writing testsuite.at): Update.
18353 2001-11-03 Akim Demaille <akim@epita.fr>
18355 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18357 2001-11-03 Akim Demaille <akim@epita.fr>
18359 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18360 (&file_name_is_absolute): New, wrappers around routines from
18362 Use and export them.
18363 (&find_configure_ac): Optionally take a directory where to look at.
18364 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18366 Default @ARGV to `.', not find_configure_ac.
18367 (&autoreconf): Argument is a directory.
18368 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18369 * doc/autoconf.texi (autoreconf Invocation): Update.
18371 2001-11-03 Akim Demaille <akim@epita.fr>
18373 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18374 (@export_forward_subs): New.
18375 Add basename, dirname, and fileparse.
18377 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18378 Don't look for aclocal flags if we already know aclocal is not
18380 Move aclocal.m4t only if it exists.
18381 Reported by Ezra Peisach.
18383 2001-11-03 Akim Demaille <akim@epita.fr>
18385 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18386 passed on command line, defaulting to ./configure.ac if present.
18387 (&maybe_autoreconf, File::Find): Remove, unused.
18388 (&autoreconf): If autoconf is not used, don't try to trace.
18390 2001-11-02 Akim Demaille <akim@epita.fr>
18392 * configure.ac: Bump to 2.52g.
18394 2001-11-02 Akim Demaille <akim@epita.fr>
18398 2001-11-02 Akim Demaille <akim@epita.fr>
18400 * config/config.guess, config/config.sub, doc/standards.texi:
18401 * config/lispdir.m4: Update from masters.
18402 * configure.ac: Bump to 2.52f.
18404 2001-11-02 Akim Demaille <akim@epita.fr>
18406 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18407 Don't run aclocal when aclocal.m4 is not from aclocal.
18409 Don't run libtoolize and gettextize if --install is not given.
18411 2001-11-01 Paul Eggert <eggert@twinsun.com>
18413 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18414 be invoked before _AS_LINENO_PREPARE.
18415 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18416 than character ranges.
18418 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18419 invoking AS_BASENAME. Set the locale variables to 'C' if
18420 possible, as POSIX requires this to get the traditional
18422 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18424 2001-10-31 Paul Eggert <eggert@twinsun.com>
18426 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18427 with {}, as that triggers a bug in Bash 2.05.
18429 (_AS_LINENO_PREPARE): Use Sed rather than
18430 Awk. Fix the sed prepass to work even if there are multiple
18431 instances of $LINENO on the same line. Do not substitute for
18432 other variables like $LINENOT. Do not check file dates; such a
18433 check is unreliable on sufficiently fast machines, and removing
18434 the check makes the code simpler and more reliable. Check for
18435 output and chmod failures.
18437 * doc/autoconf.texi (Special Shell Variables): Document
18440 2001-10-31 Akim Demaille <akim@epita.fr>
18442 * tests/Makefile.am (atconfig): Remove this target, Automake
18445 2001-10-31 Akim Demaille <akim@epita.fr>
18447 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18448 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18449 provided, while it is optional.
18450 * configure.ac: Adjust.
18452 2001-10-26 Paul Eggert <eggert@twinsun.com>
18454 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18455 lib/Autom4te/Struct.pm:
18456 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18459 * doc/autoconf.texi (Special Shell Variables): Document some
18460 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18462 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18463 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18464 eval $LINENO is not portable in practice.
18466 2001-10-24 Akim Demaille <akim@epita.fr>
18468 * lib/Autom4te/General.pm (backname): New.
18470 2001-10-24 Akim Demaille <akim@epita.fr>
18472 * m4/: Remove, merged into...
18475 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18477 * doc/autoconf.texi (Shellology): Mention the problems with bash
18478 2.05's use of ANSI quoting in its `set' builtin.
18480 2001-10-22 Paul Eggert <eggert@twinsun.com>
18482 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18483 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18484 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18485 POSIX decided to standardize on the int flavor of strerror_r.
18486 Always do char* test, as there's no reason not to.
18487 Assign to a char* var, to catch strerror_r that returns int*.
18489 * doc/autoconf.texi (Particular Functions):
18490 Document the above changes. Also, document the fact that
18491 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18493 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18495 2001-10-20 Akim Demaille <akim@epita.fr>
18497 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
18498 the executable was missing from the log.
18500 2001-10-20 Akim Demaille <akim@epita.fr>
18502 * lib/Autom4te/General.pm (&update_file): If destination is
18503 unchanged, remove the source.
18504 (&up_to_date_p): Don't be verbose, be debug.
18505 * bin/autoreconf.in: No longer support --m4dir.
18506 (&autoreconf): Display the full path of the configure.ac we are
18508 Trace it only once.
18509 Be sure to honor --force with gettextize.
18510 Always run aclocal.
18511 * doc/autoconf.texi: Adjust.
18513 2001-10-20 Akim Demaille <akim@epita.fr>
18515 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18517 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18518 `intl' is already present, as it refuses unless --force.
18519 (&parse_args): Use -I, --include instead of the old Autoconf
18521 ($localdir, $autoconf_dir): Remove.
18523 (&maybe_autoreconf): New, to preserve $_ for File::Find.
18525 2001-10-19 Jens Petersen <petersen@redhat.com>
18527 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
18528 * doc/autoconf.texi (Particular Programs): Likewise.
18530 2001-10-19 Akim Demaille <akim@epita.fr>
18532 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
18533 file in @configure_input@.
18534 Don't mention `automatically' in addition to `generated'.
18535 * tests/torture.at (#define header templates): Adjust.
18537 2001-10-19 Akim Demaille <akim@epita.fr>
18539 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
18540 comment, explain how to install automatic mode selection.
18543 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
18545 * bin/autoreconf.in (autoreconf): Display the path to the
18546 configure.ac being studied.
18548 2001-10-18 Paul Eggert <eggert@twinsun.com>
18550 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
18551 long, to work around a bug in the HP C compiler version HP92453-01
18554 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
18555 (AS_BASENAME_EXPR): New macro.
18556 (AS_BASENAME_SED): Do not assume GNU sed semantics.
18557 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
18558 and fall back on 'sed' only if the other two fail. This makes
18559 AS_BASENAME act more like AS_DIRNAME.
18560 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
18561 contains white space.
18562 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
18563 Use AS_DIRNAME, since I think it's now DOS-friendly.
18564 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
18565 Allow "dirname //FOO" to return either / or //, as POSIX allows
18568 2001-10-10 Akim Demaille <akim@epita.fr>
18570 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
18571 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
18574 2001-10-10 Akim Demaille <akim@epita.fr>
18576 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
18577 m4_define, since...
18578 (_AS_ECHO_N): AS_REQUIREs it.
18580 2001-10-10 Akim Demaille <akim@epita.fr>
18582 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
18583 (AC_INCLUDES_DEFAULT): Move to...
18584 * lib/autoconf/headers.m4: here.
18585 * lib/autoconf/types.m4: Comment changes.
18586 * doc/autoconf.texi: Specify where the default includes are used
18587 in the macro prototypes.

18598 --debug, not when --verbose.
18599 * lib/autom4te.in (Autoreconf-preselections): New.
18600 (Autoconf): Use it.
18602 2001-10-08 Akim Demaille <akim@epita.fr>
18604 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
18606 2001-10-08 Akim Demaille <akim@epita.fr>
18608 * doc/autoconf.texi (autoreconf Invocation): Adjust.

19015 * lib/autotest/general.m4: Englishoes.
19016 From Tim Van Holder and Alexey Mahotkin.

19020 * doc/autoconf.texi (Common Shell Constructs): New node,
19021 documenting AS_DIRNAME.
19022 (Limitations of Usual Tools): Refer to it when discussing dirname.

19026 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19028 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19029 Do not pass a first argument with leading '-'
19030 to expr, by parenthesizing initial integers that might be negative.
19032 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19033 now merely checks whether it is an error to pass an argument
19036 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19037 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19038 whether it is a (compile-time) error to pass an argument to
19039 getpgrp. This simpler test supports the revised documentation,
19040 and is all that AC_FUNC_GETPGRP's users really need.

19056 Add test for AS_BASENAME.
19057 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19058 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19059 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19060 * tests/base.at: Fixed the expected responses. The old ones were
19062 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19063 the documentation claims it should (and how it behaved in 2.13).
19065 2001-09-18 Akim Demaille <akim@epita.fr>
19067 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

19072 No longer to be shipped.

19079 Expect `package.m4' to define the package signature.
19080 * lib/autom4te.in (Autotest): Add `package.m4?'.
19081 * tests/Makefile.am (package.m4): New.

19101 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):

19109 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19110 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19111 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19112 when they don't exist.
19114 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19115 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

19119 version with the version used by fileutils 4.1, except use

19165 * lib/autotest/general.m4 (AT_INIT): Create and remove

19270 to avoid GCC warnings.
19273 2001-09-05 Akim Demaille <akim@epita.fr>

19277 2001-09-05 Akim Demaille <akim@epita.fr>
19279 Be ready to handle filenames as stupid as `dnl.at', for if even
19280 the maintainer is dumb enough to do that...
19282 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19283 excellence in M4 quotation: consider `__file__' is active.
19285 And BTW, when invoking m4, pass the --include in the right order:

19350 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
19351 (testsuite Scripts): There is no such thing as `atconfig.in'.

19356 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
19359 2001-08-31 Akim Demaille <akim@epita.fr>

19434 Map --localdir, --autoconf-dir onto it.
19435 Forward autom4te's options instead of interpreting them.

19437 There is no such envvar since the inception of autom4te.cfg.
19438 * bin/autom4te.in (&parse_args): Uniquify `@include'.

19459 * lib/Autom4te/General.pm (&find_peer): Remove.
19460 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
19461 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
19462 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19463 find the executables for it.
19464 * tests/Makefile.am: Major cleanup. Too lazy to document...
19465 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19467 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19468 indeed related to running the test suite, while passing
19469 --autoconf-dir and others is related to running non installed
19470 Autoconf executables. So don't do that, leave it to...

19472 * tests/autoscan: New.
19473 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19489 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
19490 Suggested by Paul Eggert.
19492 2001-08-29 Akim Demaille <akim@epita.fr>
19494 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19495 download in a tmp dir.
19497 2001-08-29 Akim Demaille <akim@epita.fr>

20036 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20038 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20039 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20040 * doc/autoconf.texi (C Compiler Characteristics): Update
20041 documentation for AC_C_BIGENDIAN.
20043 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20045 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20046 magic values from an object file when cross-compiling.
20047 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20049 2001-08-10 Akim Demaille <akim@epita.fr>
20051 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20053 Suggested by Russ Allbery.
20055 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20057 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20058 current $prefix to the sub-configures.
20060 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20062 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20063 extension (needed on BeOS). Reported by Guido van Rossum.
20065 2001-08-09 Akim Demaille <akim@epita.fr>
20067 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20069 2001-08-07 Akim Demaille <akim@epita.fr>
20071 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20073 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20074 No need to remove the files before and after the each test, before
20075 each test and at the end of the suite is enough.
20076 Display only the children `times', not the shell's.
20077 If the test failed or was skipped, at-times is not available.
20079 2001-08-07 Akim Demaille <akim@epita.fr>
20081 Always produce testsuite.log, including when there are no
20082 failures. This helps getting information on skipped tests, and
20083 duration of the tests. Err, implement the latter btw.
20085 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20086 Dump information on the first run of each test.
20087 (AT_CLEANUP): Create `at-times' containing the duration of the
20090 2001-08-07 Akim Demaille <akim@epita.fr>
20092 The use of `dumpstat' revealed that `len' was used although it
20093 should not. m4_text_wrap was using it, but in the Autoconf world
20094 where it is legal. Hence (i) test M4sh in its own world, not
20095 Autoconf's, and (ii), ahem, fix the bug :)
20097 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20098 does not like `' instead of [].
20099 (AT_INIT): Forbid `^_?AT_'.
20100 And don't output such tokens.
20101 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20102 `script.as', and `autom4te.cache'.
20103 Remove `empty' and `macro' which are no longer used.
20104 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20105 * tests/m4sugar.at: Use it.
20106 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20108 2001-08-07 Akim Demaille <akim@epita.fr>
20110 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20112 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20114 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20116 2001-08-04 Akim Demaille <akim@epita.fr>
20118 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20119 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20121 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20122 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20123 (AC_F77_MAIN): Likewise.
20125 2001-08-04 Akim Demaille <akim@epita.fr>
20127 Don't rely on M4sugar outputting the patterns in files, since we
20128 might process the output _without_ running m4, hence without these
20131 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20132 * bin/autom4te.in (@Request::includes): Remove, unused.
20133 (@Request::source): Rename as...
20134 (@Request::input): this.
20135 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20136 (&handle_output): Fetch the patterns from the traces.
20137 `$forbidden' and `$allowed' are constant: use m//o.
20138 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20139 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20141 2001-08-04 Akim Demaille <akim@epita.fr>
20143 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20144 autoconf', i.e., in addition to caching traces, cache the output.
20146 * bin/autom4te.in (Request::cache): Rename as...
20147 (Request::id): this.
20148 ($cache, $icache, $tcache, $ocache): New.
20149 (&handle_m4): Save M4 output in the cache instead of $tmp.
20150 (&handle_output): Adjust.

20157 * bin/autom4te.in ($force): New.
20158 (&parse_args, &print_usage): -f, --force is a new option.
20159 (&handle_output): CPP directives might have spaces after `#'.
20160 (&parse_args): The first file only can be frozen.
20162 2001-08-04 Akim Demaille <akim@epita.fr>
20164 Don't let autom4te compute the `include' traces several times:
20165 first check that the trace cache file is up to date, and then
20166 compare its timestamp with that of the output.
20168 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20169 the preamble. Don't require 5.005 as Autom4te::General does it,
20170 and better yet (use `use', not `require'!).
20171 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20172 Class::Struct as Autom4te::Struct.
20173 * lib/Autom4te/General.pm (File::stat): Use it.
20174 (&mtime): New, export it.
20175 * bin/autom4te.in: Use it.
20176 Declare `$req' is invalid if it is outdated.
20177 Don't declare it valid before saving it if something went wrong.
20179 2001-08-04 Akim Demaille <akim@epita.fr>
20181 Autom4te shall not encode Autoconf data, and preselecting traces
20182 must be proposed to the users.
20184 * bin/autom4te.in (@required_trace): Remove.
20186 (&parse_args, &print_usage): -p, --preselect is a new option.
20187 (&up_to_date_p): Adjust.

20192 * tests/tools.at (autoconf --trace: user macros): Check traces on
20193 macros invoked without arguments, and macros invoked with multiple
20196 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

20201 2001-08-03 Akim Demaille <akim@epita.fr>
20203 * bin/autoconf.in ($@): Work around the usual sh bug.
20206 2001-08-03 Akim Demaille <akim@epita.fr>
20208 Clean up the handling of the M4 builtins tracing exception.
20210 * bin/autom4te.in (Request::request): Don't complete M4 builtins

20213 (@m4_builtin): this.
20214 (%m4_builtin_alternate_name): New.
20215 (&parse_args): Complete the trace requests with alternate names.

20227 (m4_divert_pop): Dump the whole diversion stack when a diversion
20229 * bin/autom4te.in (&handle_output): Remember of the first
20230 occurrence of a possibly undefined macro, not the last.
20231 Complain about the possibly undefined macros in the same order as
20232 the appear in the output.
20233 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20234 * tests/tools.at (autoconf: forbidden tokens, basic)
20235 (autoconf: forbidden tokens, exceptions): No longer sort
20236 autoconf's stderr, as it is now deterministic.
20237 Check that `dnl' is caught.

20261 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
