1057 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1059 * doc/autoconf.texi (Particular Programs): Do not mention the
1060 Autoconf version in which the AC_PROG_INSTALL change was done.
1061 Suggested by Paul Eggert.
1063 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1065 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1066 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1067 mode, we change to the source directory, also set $ac_pwd so we
1068 do not go back to the build tree for the next config subdir.
1069 * tests/torture.at (Deep Package): Extend test to contain two
1070 config subdirs on the top level.
1072 Fix parallel `maintainer-check'.
1073 * Makefile.am (maintainer-check-tests): Depend on `all'.
1074 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1075 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1077 (maintainer-check): Serialize the testsuite runs.
1079 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
1080 in feature string for --enable/--with. Convert to underscore
1083 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
1084 `install -c file1 file2 dir' works.

1101 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1103 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1104 check_SCRIPTS. Building the wrappers for `all' allows help2man
1105 to use them for the manpages.
1106 Report by Benoit Sigoure.
1108 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

1119 2007-12-12 Eric Blake <ebb9@byu.net>
1121 Fix thinko in earlier patch - m4_join isn't defined yet.

1123 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1124 (m4_require): Use m4_do, not m4_join.
1126 Fix some whitespace tests on cygwin.
1127 * tests/tools.at (autom4te and whitespace in file names): Restore
1128 font-lock. Create $TMPDIR before it might be used.
1130 Fix spurious testsuite failure with M4 1.4.11.
1131 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1133 Optimize AC_REQUIRE.
1134 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1135 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1136 (m4_require): Avoid extra macro calls.
1138 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1140 * tests/torture.at (srcdir): Fix quoting.
1142 Do not pass top_srcdir to configure scripts in testsuite.
1143 * tests/autotest.at (srcdir propagation): Copy install-sh to
1145 (my only test): Drop setting of `top_srcdir'.
1146 * tests/base.at (Input/Output): Likewise.
1147 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1148 config.guess, and config.sub to test source tree.
1149 Drop AC_CONFIG_AUX_DIR setting.
1150 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1151 * tests/torture.at (Substitute a 2000-byte string): Drop
1152 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1153 (Substitute a newline, datarootdir workaround): Likewise.
1154 (Define a newline): Adjust for linenumber changes in configure.ac.
1155 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1157 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1158 if `pwd` contains whitespace.
1160 Quote $abs_top_srcdir in tests.
1161 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1162 * tests/tools.at (Syntax of the shell scripts): Likewise.
1164 * tests/m4sh.at (LINENO): Quote $0.
1166 Fix testsuite program wrapper for whitespace in `pwd`.
1167 The problem here is that the usual mantra is that command
1168 variables can contain arguments, thus we cannot just escape
1169 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1170 $top_builddir/tests directory early in $PATH, so that the
1171 wrappers are found by their plain name.
1172 * tests/wrapper.as: Put $testdir early in $PATH.
1173 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1175 Proper config.status --file/--header and $srcdir escaping.
1176 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1177 characters in $ac_file_inputs.
1178 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1180 * tests/torture.at (datarootdir workaround): Adjust.
1181 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1183 Fix Autotest for whitespace in `pwd`.
1184 * lib/autotest/general.m4 (AT_INIT)
1185 <at_func_create_debugging_script, Driver Loop>:
1186 Quote $at_group_dir.
1187 * tests/autotest.at (whitespace in absolute testdir): New test.
1189 * lib/autom4te.in: Quote @datadir@.
1191 Proper file name escaping in Autoconf programs and Perl modules.
1192 This includes escaping of characters special to the shell
1193 as well as special to Perl, e.g., leading `<' or `>'.
1194 For example, when $file starts with `>', `open ">$file"'
1195 wrongly tries to append to a different file.
1196 * bin/autoconf.as: Fix quoting for autom4te options.
1197 * lib/Autom4te/General.pm (shell_quote): New function, taken
1198 from coreutils, written by Jim Meyering.
1200 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

1206 * bin/ifnames.in: Likewise, XFile usage fixes.
1207 * tests/tools.at (autom4te and whitespace in file names): Extend
1208 test. Test twice, with special characters allowed on w32, and the
1209 rest. Test leading and trailing whitespace, for `open_quote'.
1210 (autotools and whitespace in file names): New, analogous test.
1211 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1212 by Russ Allbery and Eric Blake.
1215 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1216 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1217 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1218 (update_file, contents): Use it.
1220 * Makefile.am (autom4te-update): Rewrite for git.
1222 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1224 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1226 Fix copyright years.
1227 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1228 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1230 2007-12-04 Eric Blake <ebb9@byu.net>
1232 Manually resync with gnulib, since 'make cvs-update' no longer works.

1238 * doc/Makefile.am (TEXINFO_TEX): Add.
1240 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1242 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1243 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1244 #undef as this runs afoul of our new way of creating config.h.
1245 Problem reported by Jim Meyering in
1246 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1250 Fix autom4te for unusual characters in input file names.
1251 * bin/autom4te.in (files_to_options): Quote active characters
1253 * tests/tools.at (autom4te and white space in file names):
1256 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1257 Document that Tru64 awk always splits $0.
1259 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1261 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1262 `#AT_STOP_...' line at the end of each test.
1264 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1266 * lib/autotest/general.m4 (AT_INIT): For awk line number
1267 extraction script, ensure `$at_group' has a defined value
1268 even for the empty set, and properly quote its usage inside
1271 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1273 * doc/autoconf.texi (Shell Functions): New chapter. Document
1274 IRIX sh $0 issue in functions, move content from ...
1275 (Portable Shell): ... here.
1276 (Shell Script Compiler): Note that shell functions are not
1277 totally unportable any more.
1279 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1280 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1282 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1283 extracting the line numbers of the last needed test.
1285 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1290 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1292 Fix IRIX testsuite debugging failures: $0 in functions.
1293 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1294 Do not use $0 inside a function, as IRIX sh will set that to the
1295 function name rather than the script invocation name.
1297 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1298 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1300 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1301 to extract test scripts.
1302 (AT_INIT): Extract and cache test script line numbers.
1304 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1306 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1307 subsequent fixups; the awk -> here-document conversion trashes
1308 performance too much with AIX sh.
1310 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1312 * tests/local.at: Do not test m4, perl with AT_TESTED.
1314 Diagnose and guard against write errors dealing with config.status.
1315 The general idea is this: all write failures from `configure'
1316 writing `config.status' are indicated by $ac_write_error, which
1317 is only checked at the end. This is safe because config.status
1318 code is not executed before the file is complete. Other write
1319 failures, be they inside config.status, or in sub shell/awk
1320 scripts spawned from configure or config.status, typically need
1321 earlier checking, as their results are used right afterwards.
1322 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1323 before writing config.status, check afterwards.
1324 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1325 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1326 Set `ac_write_error' for write failures to config.status. Barf
1327 upon write failures to temporary files.
1328 Adjust note about closing and reopening the here-document.
1329 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1330 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1331 reopening the here-document.
1332 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1333 Ensure `ac_write_error' does not escape into config.status.
1334 Also, add a couple of code paths not yet exercised in the test
1335 suite: a config file with input from stdin, and a config header
1337 Suggestion for catching write errors by Bruno Haible.
1339 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1341 Avoid error with Tru64 awk and testsuite lines with many words.
1342 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1343 reads the testsuite, set the field separator to an unusual value,
1344 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1345 even splits the input if $i, i>0, was never accessed in the script.
1347 Revert 2007-10-17 change.
1348 * TODO: Multiline args in config files and headers mean something
1349 different and are not fixed, see
1350 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

1355 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1357 AC_*_TOOL does not canonicalize the prefix
1358 * doc/autoconf.texi (Generic Programs): Do not say that

1363 Diagnose write errors in config.status instantiations.
1364 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1367 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1383 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1384 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1386 * lib/autotest/general.m4 (at_func_test): Remove.
1387 (AT_INIT): Pre-extract test groups into separate files.
1388 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1389 Remove at-test-source files together with the $at_group_dir.
1390 * tests/autotest.at (Long test source lines): New test.
1392 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1394 Shell functions and variables may share a namespace.

1400 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1403 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1405 * lib/autoconf/status.m4: Fix a couple of comment typos.
1407 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1409 2007-11-13 Jim Meyering <meyering@redhat.com>
1411 Clean up the rule to create "expr".
1412 * tests/Makefile.am (expr): Don't redirect directly to target.
1413 Redirect just once, not for each echo statement.
1414 Use $@, not literal "expr".
1416 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1418 Don't worry about preprocessor when testing long long.
1419 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1420 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1421 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1422 These no longer check for preprocessor flaws.
1423 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1424 Do not check for preprocessor flaws.
1426 2007-11-13 Jim Meyering <meyering@redhat.com>
1428 Adapt dependencies, now that a version change doesn't modify configure.ac
1429 * GNUmakefile: Remove "make clean" kludge.
1430 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1432 Don't redirect directly to target.
1433 Use $@, not literal "version.m4".
1435 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1438 ":;{" shorthand as in previous patch.
1440 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1442 * doc/autoconf.texi (Limitations of Builtins): Document problem
1443 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1445 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1446 Use ":;{" shorthand.
1447 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1449 2007-11-12 Jim Meyering <meyering@redhat.com>
1451 Add more non-srcdir build support.
1452 * GNUmakefile (dummy): Split a long line.
1453 Add -v option to autoreconf invocation.
1455 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1456 * GNUmakefile (dummy): Remove INSTALL.
1458 Remove racy commands to build scripts in bin/ and tests/.
1459 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1460 are guaranteed to be built, remove the rules that tried to build
1461 them. Before, with a parallel build, these rules could lead to
1462 two processes writing tests/wrapper.in concurrently.
1464 Build in man/ only *after* building in bin/ and tests/.
1465 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1466 in both bin/ and tests/.
1468 Accommodate non-srcdir build-from-checkout.
1469 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1470 Use git's --git-dir=$srcdir/.git option.
1471 Add quotes, in case tarball_version_file contains shell meta-characters.
1472 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1473 * configure.ac: Pass "." to git-version-gen.
1475 Avoid spurious test failures due to version skew.
1476 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1483 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1484 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):

1503 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1505 Ignore configure --help* errors due to LINENO-impaired shells.
1506 * tests/torture.at (Configuring subdirectories, Deep Package):
1507 In the --help* tests in read-only trees, make `.' temporarily
1508 writable again for the `stderr' file, and ignore errors due to
1509 the attempt to write configure.lineno.
1510 Report by Patrick Welche.
1512 2007-11-10 Jim Meyering <meyering@redhat.com>
1514 Generate package.m4 in build-dir, not srcdir.
1515 * tests/Makefile.am (package.m4): Adjust target.
1516 Don't redirect directly to $@.
1517 (CLEANFILES): Add package.m4.
1518 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1520 When running $(AUTOTEST), search "." before searching $(srcdir).
1522 Avoid a race condition that would make parallel "distclean" fail.
1523 * tests/Makefile.am (distclean-generic): Replace the default,
1524 automake-provided rule with an identical one, but with an additional
1525 dependency on distclean-local. Simply adding the dependency would
1526 cause automake not to emit the rule at all.
1527 * BUGS: Building with -jN works, now.
1529 Distribute git-version-gen.
1530 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1531 since GNUmakefile is distributed, and requires it for dist* rules.
1533 Remove two more generated files from version control.
1534 * INSTALL: Remove generated file.

1559 Adjust the documentation of autotest WRT atlocal.
1560 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1561 when using Automake, to write a rule to produce atlocal, since it's
1562 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1563 distributed, not atconfig.in.

1588 "make check" to ensure that the latter passes.
1590 Use just-built tools, when possible.
1591 * GNUmakefile (PATH): Set and export here, ...
1592 (dummy): ... rather than here.

1662 2007-10-28 Jim Meyering <meyering@redhat.com>
1664 Make inter-release --version output more useful.
1666 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1667 which indicates that it is built using the 19th change set
1668 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1669 is a prefix of the commit SHA1.
1670 * build-aux/git-version-gen: New file.
1671 * configure.ac: Run it to set the version.
1672 (AM_INIT_AUTOMAKE): Don't check NEWS here.

1675 * .gitignore: Add .version here, too. Just in case.
1676 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1677 not configure.ac, now that the version number changes automatically.
1679 Ensure that $(VERSION) is up to date for dist-related targets.
1680 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1681 git-version-gen doesn't match $(VERSION), but only for dist targets.

1723 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1725 Don't check for bug in HP-UX 11.00 cpp.
1726 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1727 Use -1ull rather than -1u, since that causes problems with gnulib; see

1752 this resolution. Fixes test failure on FreeBSD.
1754 Fix config header generation with AIX awk.
1755 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1756 script, use helper array D_is_set, as `" 0"' does not evaluate

2980 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2981 works but the latter doesn't, then it's a valid type.

2983 For C++ there doesn't seem to be a simple solution, so leave it alone.
2984 (AC_CHECK_SIZEOF): Allow argument to be a variable.

3047 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3049 * doc/autoconf.texi (Specifying Names): `--host' does not
3050 change the build type.
3052 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

3072 extra argument ACTION-IF-UNIVERSAL.
3073 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3074 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3075 Reindent for sanity's sake.
3077 2007-02-24 Eric Blake <ebb9@byu.net>
3079 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

3085 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3087 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3088 status of rm so we know when it failed.
3089 If cleaning of test dir failed before running the test, warn.
3090 Output the line separator in verbose mode before the warning
3091 to make clear the warning belongs to the following test.

3118 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3119 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3120 will not wait for input with a script containing only a BEGIN

3156 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3157 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3158 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3159 substitution will still be done by the special code.

3175 Report against Automake by Patrick Welche.
3177 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3179 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3181 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3183 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3184 early on the reader side, drop stderr of the input to avoid
3185 `broken pipe' error output; this may happen even with shell
3186 builtin `echo' of some bash versions. Reports by Ian Macdonald
3187 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3189 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3191 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3192 separate items of `ac_user_opts', to avoid long lines.
3193 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3195 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3201 Fix some wording problems noted by Paolo Bonzini in:
3202 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3203 * doc/autoconf.texi (Signed Overflow Examples): Give more
3204 discussion about the allow_superuser_privileges example,
3205 and change it a bit to make things clearer.
3206 (Optimization and Wraparound): Clarify whether the compiler
3207 will generate an infinite loop for the example derived from
3208 Autoconf's mktime test.
3209 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3210 Also, clarify unsigned multiplication overflow.
3212 2007-01-04 Eric Blake <ebb9@byu.net>
3214 * bin/Makefile.am (RELEASE_YEAR): New macro.
3215 (edit): Use it to supply correct copyright year to scripts.
3216 * bin/autoconf.as (version): Use it.
3217 * bin/autoheader.in ($version): Likewise.
3218 * bin/autom4te.in ($version): Likewise.
3219 * bin/autoreconf.in ($version): Likewise.
3220 * bin/autoscan.in ($version): Likewise.
3221 * bin/autoupdate.in ($version): Likewise.
3222 * bin/ifnames.in ($version): Likewise.
3224 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3226 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3227 feedback. The most important changes document what happens when
3228 you convert an out-of-range value to a signed integer type, and
3229 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3232 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3233 rewrite, taking notions from the recent discussion on the gcc and
3234 autoconf mailing lists; please see
3235 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3236 and follow the many links.
3237 (Integer Overflow Basics, Signed Overflow Examples):
3238 (Optimization and Wraparound, Signed Overflow Advice):
3239 (Signed Integer Division): New sections.
3241 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3243 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3244 preprocessor macro arguments in traced name.
3245 * doc/autoconf.texi (Defining symbols): Document longstanding
3246 support for AC_DEFINE-ing macros with arguments, and document
3247 behavior when the same variable has multiple AC_DEFINEs.
3248 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3249 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3250 macros directly, giving much shorter and simpler code.
3252 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3254 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3255 space before "$ac_configure_args" to prevent a 'config.status
3256 --recheck' failure if ac_configure_args doesn't contain a leading
3257 space. This works around a problem with the XEmacs configure.ac,
3258 which uses the (undocumented) ac_configure_args variable
3259 inconsistently with Autoconf.
3261 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3263 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3264 Include <limits.h>, and use its INT_MAX to rewrite the
3265 j loop so that it does not overflow 'int'. Problem reported by
3267 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3268 Play it safe by shifting left by 1 rather than multiplying by 2,
3269 as GCC is less likely to optimize this away when the value
3270 is signed (when it assumes overflow leads to undefined behavior).
3271 Also, don't assume time_t uses two's complement.
3273 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3275 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3276 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3277 dumps core on it. Report by Tim Rice.
3279 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3281 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3282 --disable-option-checking to --help output even when
3283 AC_PRESERVE_HELP_ORDER is not used.
3284 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3285 --with argument, rather than argument with [-.] replaced by
3287 * NEWS: Fix typo in previous change; the news was in the
3290 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3292 * NEWS: Warnings are now generated by default for unknown
3293 --enable-* and --with-* options.
3294 * doc/autoconf.texi (Option Checking): Renamed from
3295 (Configure Option Checking). Tighten up the wording a bit.
3296 (External Software, Package Options): Cross-reference to Option
3297 Checking, and use this to shorten our section.
3298 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3299 "$x" to test "x$foo" != x.
3300 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3301 Don't warn if $enable_option_checking is "no".
3302 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3303 ac_unrecognized_opts to the empty string.
3304 Don't echo the unrecognized opts, as this might mishandle
3305 backslashes or leading -.
3306 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3307 usage next to the other --disable-FEATURE options in the
3310 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3312 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3313 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3314 Print warning for unrecognized --with and --enable options
3315 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3316 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3317 Disable option checking when subdirs are configured.
3318 (AC_OUTPUT): If warnings are enabled, print warning about
3319 unrecognized --with and --enable options at the end of
3320 the configure output (as well as at the beginning).
3321 * doc/autoconf.texi (Option Checking): New node.
3322 Document new option warning functionality.
3324 2006-12-16 Eric Blake <ebb9@byu.net>
3326 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3327 * NEWS: Start news for current version.
3329 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3331 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3332 Define HAVE_GETMNTENT to 1, not to the empty string.
3333 Problem originally reported by Jochen Friedrich in
3334 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3336 This change prompted by a problem report by Andrey Simonenko in
3337 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3338 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3339 object-like macros only, in the traditional portable character
3341 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3342 Warn about attempts to define things that are not identifiers.
3343 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3344 awful hack that AC_DEFINEd macro names containing parentheses.
3346 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3348 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3349 too drastic, even if Texinfo in theory requires it for info mode.
3351 (config.status Invocation): Renamed back from Recreating a
3353 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3354 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3356 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3358 * NEWS: Version 2.61a.
3360 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3361 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3363 * NEWS: Document changes with echo and printf, and the lack
3364 of limits on the total size of multi-line values of substituted
3365 variables, and the AC_FUNC_FSEEKO fix.
3367 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3369 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3370 Writing configure.ac.
3371 (Autoconf Input Layout): Renamed from configure.ac Layout.
3372 (Recreating a Configuration): Renamed from config.status Invocation.
3373 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3374 (acconfig Header): Renamed from acconfig.h.
3375 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3376 (Writing Testsuites): Renamed from Writing testsuite.at.
3377 (Autom4te Cache): Renamed from autom4te.cache.
3379 * BUGS: Remove mention of VPATH problem, since it's now documented
3380 not to be a bug in the Autoconf build procedure itself, but rather
3381 a problem with the proprietary `make' programs.
3383 * doc/autoconf.texi (Build Directories): Add a cross reference
3386 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3387 * doc/standards.texi: Sync from gnulib.
3389 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3390 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3391 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3392 generated automatically.
3394 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3396 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3397 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3398 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3400 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3402 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3403 `CEOF$ac_eof' special marker, the awk script cannot contain a
3404 line matching `^CEOF', so this is not needed any more.
3405 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3406 special marker in the test.
3408 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3410 * tests/tools.at (autom4te preselections): Use `find -newer';
3411 remove one of the sleeps.
3413 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3414 more readable, using ...
3415 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3417 * doc/autoconf.texi (autoheader Invocation): Do not double-
3418 quote the parameter of `AH_BOTTOM' in the example.
3420 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3422 * doc/autoconf.texi (Configuration Headers): Remove the
3423 example with multiple input files.
3424 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3425 multiple input files.
3427 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3429 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3430 creating the awk substitution script, handle one input line at a
3431 time, so that the maximum length of a substituted (multi-line)
3432 value is not limited by the size of the sed pattern space.
3433 The trade-off is a slightly repetitive sed script.
3434 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3435 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3436 * tests/torture.at (Substitute a 2000-byte string): Increase the
3437 test with several long lines, they should not be caught by sed
3440 * tests/tools.at (autom4te preselections): New test, to flag
3441 entries missing from autom4te.cfg.
3442 Report by David Byron <dbyron@hheld.com>.
3444 * tests/torture.at (Substitute a 2000-byte string): Actually use
3445 AC_PROG_AWK, so the last change works as intended.
3446 (Substitute and define special characters): Likewise.
3447 (Substitute a newline): Likewise.
3449 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3450 instead of `awk' consistently.
3451 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3452 * tests/torture.at (Torturing config.status): Test both the
3453 result of AC_PROG_AWK and plain awk.
3454 (Substitute a 2000-byte string): Likewise.
3455 (Substitute and define special characters): Likewise.
3456 (Substitute a newline): Likewise.
3458 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3460 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3461 can be assigned to a function pointer. Problem reported by
3462 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3463 part of a patch by Ralf Wildenhues in that same bug report.
3465 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3467 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3468 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3470 2006-12-01 Eric Blake <ebb9@byu.net>
3472 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3473 cross-compiling from cygwin to mingw.
3474 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3475 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3476 to lib/autoconf/c.m4.
3478 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3480 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3481 string for more reliable failure. Wrap the entire test that
3482 causes the broken Solaris printf to dump core, in a subshell,
3483 so the segmentation fault message is reliably suppressed.
3484 Fix shell expansion errors by using /usr/ucb/echo always;
3485 avoid an error on systems without it by another subshell.
3486 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3487 subshell-$as_echo to `as_echo', for better error message.
3489 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3491 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or

3495 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3497 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3498 years and is too hard to maintain now. The last straw was
3499 reported by Jerker Baeck in
3500 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3501 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3502 * doc/autoconf.texi (Particular Functions): Move
3503 AC_FUNC_SETVBUF_REVERSED from here...
3504 (Obsolete Macros): ... to here. Say that it does nothing now.
3505 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3506 Turn into (almost) a no-op.
3508 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3510 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3511 These macros are obsolescent and new applications shouldn't need them.

3519 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3521 * doc/autoconf.texi (Setting Output Variables): Mention that
3522 @VAR1@VAR2 has unspecified behavior. Problem reported by
3524 * NEWS: Mention this.
3526 * Makefile.am: Put only a single '#' into the copyright notice,
3527 so that it's also present in the output file. Standardize wording
3528 in makefile copyright notices to match GNU coding standards.

3544 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3545 in the sed script that mangles the awk script: delete up to the
3546 first exclamation mark only.
3547 * tests/torture.at (Substitute and define special characters):
3550 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3552 Rewrite config files generation: avoid quadratic growth in
3553 the number of substituted variables by using awk instead of sed
3554 for the bulk of the substitutions.
3555 * NEWS: Mention this.
3556 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3557 forbidden in the output (and thus input) file.
3558 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3559 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3560 generate just one large awk script for substitutions,
3561 eliminating much of the earlier complexity, while adding some
3562 new complexity. Only expand the substitution templates at
3563 configure time, for smaller configure script size. If
3564 _AC_SUBST_FILES are used, test 'awk' for working getline support
3565 at config.status time. If absent, interpolate through the
3566 shell. The awk script was written with much help
3567 from Paolo Bonzini and Paul Eggert.
3568 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3569 (_AC_SED_FRAG_NUM): Likewise.

3572 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3573 * tests/torture.at (Substitute a 2000-byte string): Also
3574 substitute a line with 1000 words, and a variable with several
3576 (Substitute and define special characters): Test awk special
3577 characters, and put substitution input strings `@foo@' in the
3578 output, to test that no recursion happens; test several other
3579 combinations from Paolo Bonzini.
3581 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3583 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3584 that replaced echo with AS_ECHO where this wasn't necessary.
3585 Problem reportd by Ralf Wildenhues.
3586 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3587 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3588 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3590 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3592 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3594 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3596 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3597 that traditional Awk lacks 3-arg "split". It has it.
3598 Mention that FS must be a single character, and a few other
3599 99-byte limits of traditional Awk.
3600 Mention that if (i in a) doesn't work with traditional Awk.

3606 (Newline-CODE-BS-newline in command):
3607 (Single-quote-BS-newline in command):
3608 (Single-quote-newline-BS-newline in command):
3609 Use printf '%s\n' instead of echo, for portability to hosts
3610 where echo interprets backslashes. This will break on hosts
3611 that lack printf, but for now let's assume all such hosts
3612 are dead (if not, we should get reports of test failures).
3614 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3616 'echo' has some portability problems, when given a first argument
3617 with a leading '-', or when given any argument containing '\'.
3618 Avoid using 'echo' in these cases.

3643 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3644 * bin/autoconf.as: Redo verbose flag implementation, as the old
3645 scheme wouldn't work with AS_ECHO.
3646 * lib/autotest/general.m4 (AT_INIT): Likewise.
3647 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3648 Don't use ECHO_T, since ECHO_N is now reliable.
3649 * lib/autotest/general.m4 (AT_INIT): Likewise.
3650 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3651 rather than using a here-document to put the script into a file.
3652 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3654 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3655 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3656 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3657 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3658 * lib/autotest/general.m4 (AT_SETUP): Likewise.

3660 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3661 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3662 operand, as AS_ECHO requires. Avoid double file name expansion.
3663 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3664 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3665 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3666 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3667 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3668 Double-quote strings that would otherwise contain M4 comments.
3669 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3671 * configure.ac (AC_INIT): Bump to 2.61a.
3674 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3678 * configure.ac (AC_INIT): Bump to 2.61.
3681 * tests/autotest.at (Macro with backslash in a test title):
3682 Comment out for now, as this tests neither fails nor passes
3683 reliably. Problem reported by Ralf Wildenhues.
3685 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3687 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3688 in previous change, which caused test failures.

3798 and Stepan Kasal <kasal@ucw.cz>
3800 Handle special characters in test case titles correctly.
3801 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3803 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3804 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3805 argument. Extend to check titles printed by ./micro-suite and
3806 ./micro-suite -l and the title in micro-suite.log.
3807 (Backquote in a test title,
3808 Single-quote in a test title,
3809 Double-quote in a test title): Don't expect failure anymore.
3810 (Backslash in a test title): Put a non-whitespace character after the
3811 backslash so that Bourne shells might actually see it as an escape
3813 (Brackets in a test title,
3814 Pound in a test title,
3815 Comma in a test title,

3833 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3834 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3835 5363) simply issues a warning when dividing by zero at compile

3870 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3871 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3872 reported by Nelson H. F. Beebe for Coreutils 6.4.
3874 * tests/tools.at (autoconf --trace: user macros): Remove test
3875 for tracing multiline macros, since m4 1.4.7a uses a different

3952 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3954 (Imported from Automake.)
3955 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3956 which incorrectly sets the mode of an existing destination
3957 directory. In some cases the unpatched install-sh could do the
3958 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3959 system. We hope this is rare in practice, but it's clearly worth
3960 fixing. Problem reported by Alex Unleashed in
3961 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3962 Also, don't bother to check for -m bugs unless we're using -m;
3963 suggested by Stepan Kasal.

3972 Report from Bruno Haible.
3974 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4012 added to the template can get mangled.
4014 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4016 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4017 include the default headers, and redefine obstack_chunk_alloc

4037 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4039 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4040 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4041 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4042 Use a better substitute, by inspecting the output of "ls"
4043 rather than just using ":".
4044 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4045 rather than AS_EXECUTABLE_P, since we needn't worry about
4046 non-regular files here.
4048 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4049 due to configuration hassles with this. See Tonya Underwood's report

4061 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4062 initialization which is not inherited through the environment
4063 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

4071 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4073 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4074 comment about ac_cpp_err; it was incorrect, and anyway
4075 ac_cpp_err is being removed below.
4076 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4077 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4078 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4080 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4081 with werror_flag and conftest.err and so forth. This is more
4082 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4083 and anyway the user shouldn't normally want to see this gorp logged.
4084 Problem reported by Ralf Wildenhues.
4085 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4086 empty, not 'no', since the rest of the code uses 'test -z'.
4088 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4090 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4091 Use a single call to AC_DO_TOKENS rather than multiple, for
4093 (_AC_LINK_IFELSE): Test that resulting file is executable.
4094 Problem reported by mwoehlke in
4095 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4097 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4098 than creating a file to use with test -x; this is much faster.
4100 2006-10-02 Bruno Haible <bruno@clisp.org>
4102 * lib/autom4te.in (Automake-preselections): Add
4103 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

4112 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4113 fseeko testing program twice; just use the earlier result.
4114 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4115 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4116 still doesn't let the program compile.
4117 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4120 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4121 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4122 include it, without including anything else.
4123 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4125 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

4130 `error.h', and include it, for a `error_at_line' prototype.
4131 Use a nonempty format string in the link test.
4132 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4133 for a declaration of wait3.

4139 can apply to constants too, and that it checks for macro defns.
4140 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

4142 values. Problem reported by Ralf Wildenhues.

4237 7.1.4 /usr/bin/posix/sh described by Tim Rice in

4357 broken lex libraries like native ia64-hp-hpux11.22; see
4358 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4486 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4487 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4488 -Wundef -Werror". Problem reported by David Fang in

4549 less skeptical about "volatile", after discussion with
4550 Bruno Haible on bug-gnulib.
4551 (Limitations of Usual Tools): Warn about sed stripping
4552 leading white space from text. From Bruno Haible.
4554 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4556 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4557 compiler complains about it, even if things works after the
4558 complaint. Problem reported by Peter O'Gorman.

4579 under AC_C_VOLATILE.
4580 (Volatile Objects): Be a little less skeptical about what
4581 "volatile" means. Derived from thoughts by Ben Pfaff in
4582 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

4588 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4590 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4591 more globally, since the 2006-06-30 patch didn't suffice. Problem
4592 reported by Keith Marshall. Also, don't bother with builddir2,
4593 since it shouldn't be needed any more.
4595 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4614 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4616 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4617 Require that long long int be at least 64 bits wide. C99 requires
4618 this and enough programs depend on it so we should check for it.
4619 Bruno Haible reports in
4620 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4621 that long long int is 32 bits wide with some nonstandard compilers.
4622 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4624 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4626 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4627 to a nonexistent file, so that we don't have to worry about
4628 a local site configuration that doesn't use /usr/local.
4629 Problem reported by Keith Marshall in
4630 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4632 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4634 * doc/autoconf.texi: Be more consistent about using @acronym with
4635 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4636 quite right (it talked about "OSF/Tru64", even though the
4637 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4638 and it even mentioned "OSF 4"!) and at this point there's little
4639 reason to talk about OSF any more, since it died in 1994.
4640 (Specific Compiler Characteristics): Simplify example of
4641 negative-size array.
4642 (File Descriptors): Reorder to make the text flow better.
4643 Remove joke about "appreciate the various levels"; I didn't get it.
4644 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4645 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4646 (File Descriptors, Limitations of Usual Tools):
4647 Tone down the advice against renaming or removing open files.
4648 (Limitations of Usual Tools): Add a new section, on 'rm'.
4650 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4652 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4653 -lXt in LIBS, idea from Karsten Hopp; this was due since
4656 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4657 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4658 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4659 (which belong to Xt, not X itself). See Debian bug 327655.
4661 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4683 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4685 * doc/autoconf.texi (Changed Directory Variables): New node,
4686 to document the whole `datarootdir' business a bit better.
4688 * tests/torture.at (datarootdir workaround): Extend test.
4689 Prompted by report by Alexandre Julliard.
4691 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4693 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4694 when using default mode of IBM C 6 for AIX. Problem and two-line
4695 fix reported by Larry Jones.
4697 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4699 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4700 about literal '${datarootdir}' if a definition is found in the
4703 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4705 * NEWS: Use "M4" rather than "m4" when appropriate.
4706 Problem reported by Eric Blake.
4707 * doc/autoconf.texi: Likewise.
4708 Use @acronym around BSD, GCC, and GNU when appropriate.
4709 (Why GNU M4): Renamed from "Why GNU m4".
4710 (Redefined M4 Macros): Mention that Posix
4711 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4712 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4715 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4717 * bin/autom4te.in (handle_output): Do not forbid the empty
4719 * tests/tools.at (autoconf: the empty token): New test.
4721 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4723 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4724 calls, so that we do not care whether they are LIFO or FIFO;
4725 in the m4_wrap, do not check which diversion is the topmost
4726 one, just check that the stack is balanced at the end.
4727 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4728 base diversion forever--pop the previous diversion before
4729 opening the new one; consequently, remove the m4_wrap call.
4730 * lib/autotest/general.m4 (AT_INIT): Likewise.
4731 * tests/m4sugar.at: Do not use
4732 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4735 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4737 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4738 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4739 Rework example of m4wrap token-pasting trouble so that it doesn't
4740 care whether it's LIFO or FIFO.
4741 Fix some "contrary to"s that are awkward in English.
4743 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4745 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4746 to `yes' instead of `int$1_t' if the type is found, for more
4747 consistent configure output (where $1 is the number of bits).
4748 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4749 Suggested by Bruno Haible.
4751 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4752 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4753 with system headers. Report by Bruno Haible.
4755 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4757 * config/config.guess, config/config.sub: Sync from upstream.
4759 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4760 in order to avoid picking up an older installed frozen m4sh.m4f.
4761 Besides an outdated shell startup, this could have been created
4762 by an earlier M4 version with incompatible frozen file format.
4764 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4766 * README: Recommend m4 1.4.4 instead of 1.4.3..
4767 * doc/autoconf.texi: Likewise.
4768 (Special Chars in Names): Say that $(.FOO) is portable, as
4769 suggested by Stepan Kasal.
4770 (Installation Directory Variables, Build Directories):
4771 (Automatic Remaking, Subdirectories, Fortran Compiler):
4772 (Making testsuite Scripts, Defining Directories):
4773 Quote variable usages better.
4774 (Making testsuite Scripts): Add clean-local rule to makefile
4775 snippet, by Eric Blake.
4776 (Installation Directory Variables): Fix table item font.
4777 Reword slightly to clarify. Generalize advice about
4778 not using special characters to include all file-related
4779 vars, not just VPATH.
4780 (Special Chars in Variables): Warn about special characters in
4782 (Assignments): Clarify default-value example as suggested by
4784 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4785 (Special Shell Variables): Note leading ./ or ../, as suggested
4787 (Limitations of Builtins): Under cd, warn about CDPATH.
4788 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4791 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4793 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4794 `@var', for texi2html.
4795 (Systemology): Some more word wrapping, for DVI output.
4796 (autom4te Invocation): The short option for `--melt' is `-M',
4799 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4801 * doc/autoconf.texi: More formatting and English tweaks,
4802 many suggested by Ralf Wildenhues.
4803 Reword to avoid "@code{...}'s" and the like, since it's ugly
4804 with Emacs info mode. discontents -> woes.
4805 Put a few "will"s back. time stamp -> timestamp.
4806 side-effect -> side effect.
4808 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4810 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4811 Warn about $@ not persisting. Problem reported by Julien Danjou in
4812 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4813 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4814 Mention other special chars, too.
4816 2006-06-14 Eric Blake <ebb9@byu.net>
4818 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4820 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4822 * doc/autoconf.texi: Some systematic minor improvements, as
4823 follows. Use "makefile" when talking about makefiles
4824 generally (which might be named "makefile" or "Makefile" or even
4825 "foo.mk"), "Makefile" when talking about a specific makefile
4826 called "Makefile". This unclutters the text from weird quotes
4827 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4828 values" rather than "@var{foo}s" and similar constructs containing
4829 "}s". Use "Make rules" rather than "Makefile rules". Minor
4830 English-language improvements. Change the prefix "sub-" to "sub"
4832 Put blank lines around examples more consistently.
4833 Avoid "rather" and "very" as intensifiers.
4834 Avoid "will" as an auxiliary.
4835 (Limitations of Make): Split this node into....
4836 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4837 (Leading _ in Macro Names, Backslash-Newline-Newline):
4838 (Backslash-Newline Comments, Long Lines in Makefiles):
4839 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4840 (obj/ and Make, make -k Status, VPATH and Make):
4841 (VPATH and Double-colon, $< in Explicit Rules):
4842 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4843 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4844 New nodes, resulting from splitup of Limitations of Make.
4845 All cross-references changed. Raise the top node from
4846 a section to a chapter, and all subnodes accordingly.
4847 Redo the introductory wording to match the new organization.
4848 (Installation Directory Variables): Use an example that is
4849 closer to what Autoconf actually does. Mention that VPATH's
4850 value should not contain metacharacters or white space.
4851 (Fortran Compiler): Fix a VPATH bug in an example.
4852 (Leading _ in Macro Names): Mention that this problem is no longer
4853 of practical concern.
4854 (VPATH and Make): Reword the advice to make it clearer
4855 that Autoconf and Automake support VPATH in non-GNU make, but
4856 many packages have bugs in this area.
4857 ($< in Explicit Rules): Refer to Build Directories rather
4858 than using a (non-VPATH-safe) example.
4859 (Automatic Rule Rewriting): Mention the sort of disaster that
4860 can ensue with Solaris-style rule rewriting with VPATH.
4862 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4864 * doc/install.texi (Compilers and Options): Weaken the
4865 suggestion to use GNU make for VPATH builds.
4867 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4868 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4870 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4871 in regular expression.
4873 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4875 * doc/autoconf.texi (Installation Directory Variables):
4876 Drop extra @samp from `@table @samp' item.
4877 (Limitations of Usual Tools): Comment fix.
4878 Do not nest @samp just to point to other table items.
4879 (Writing testsuite.at) <AT_CHECK>: The second argument to
4880 `@dvar' is already @samp'ed.
4881 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4882 do not use @var in the second argument.
4884 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4886 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4887 $as_shell.exe too. Problem reported by Andreas Buening in
4888 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4890 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4892 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4893 `unused variable' compiler warning, for `-Wall -Werror'.
4894 Reported by Jaap Haitsma in
4895 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4897 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4899 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4900 case the compiler dumps core. Problem reported for
4901 OpenServer 5.0.7 by Tim Rice in
4902 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

4906 2006-06-06 Tim Rice <tim@multitalents.net>.
4908 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4909 "ERROR" only shows up in "make check" output if there is an
4912 2006-06-06 Eric Blake <ebb9@byu.net>
4914 * tests/tools.at (automatically allowed tokens): Fix typo.

4933 * config/texinfo.tex: Sync from upstream.
4935 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4936 seen, invoke libtoolize with `--ltdl' argument.
4937 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4939 Suggested by Eric Blake.
4941 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4943 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4944 reported by Ralf Wildenhues.

4951 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4953 * doc/autoconf.texi: Modernize some of the references to Solaris.
4955 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4957 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4958 message issued by AC_REQUIRE.
4959 * tests/m4sugar.at: Check m4_require's error message.
4960 * tests/base.at: Check AC_REQUIRE's error message.
4961 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4963 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4965 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4966 `expout' as the last parameter.
4967 * tests/tools.at: Adapt to the above change.
4969 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4971 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4972 information about race-free implementations of mkdir.

4981 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4983 * NEWS: GNU make now recommended for VPATH builds.
4984 Mention that some macros are now documented to be obsolescent.
4985 * doc/autoconf.texi:
4986 Prefer "current" to "modern" to describe
4987 currently-used (albeit perhaps old-fashioned) hosts.
4988 Mention which ancient features no longer need to be worried about.
4989 setgid -> set-group-ID
4990 setuid -> set-user-ID (these are the Posix terms)
4991 Fix some misuses of "only".
4992 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4993 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4994 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4995 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

5001 Mention that these macros are obsolescent.
5002 (Installation Directory Variables): shall -> should
5003 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5004 Mention that it's now safe to use 3 and 4.
5005 (Limitations of Usual Tools): cp -r is now specified by Posix.
5006 Omit longwinded and obsolescent discussion of cp -f.
5007 Modernize discussion of expr, ls.
5008 (Limitations of Make): Modernize discussion of VPATH builds.
5009 Mention $? as a workaround in some cases.
5010 * doc/install.texi (Basic Installation):
5011 Mention "./configure; make; make install" first. Be more
5012 specific about why this file is generic. Remove unnecessary
5013 parens. Remove misleading "only". Remove obsolete advice
5014 about csh. Don't say "configure" takes awhile; say it
5015 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5016 and CC=c99 rather than CC=c89, as these are blessed by current
5017 Posix. Recommend GNU make if doing a VPATH build.
5019 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5021 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5022 examples involving shell prompts.
5024 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5025 and Paul Eggert <eggert@cs.ucla.edu>
5027 * doc/autoconf.texi (Here-Documents): Add details about the
5028 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5029 use "here-documents" instead of "here documents".
5031 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5033 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

5037 * doc/autoconf.texi (File System Conventions): Warn about ":"
5038 anywhere in directory names.
5040 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5042 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5043 about quoting the case statement, just in case.
5044 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5045 was fixed in ksh93g; reported by Ralf Wildenhues.
5047 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5049 * doc/autoconf.texi (System Services): Do not document
5050 overriding EXEEXT via ac_cv_exeext=ext.
5051 (Particular Programs) <AC_PROG_MKDIR_P>:
5052 Document that ${MKDIR_P} understands --.

5056 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5058 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5059 argument with leading hyphen. Problem reported by Paul Eggert.
5061 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5063 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5064 about quoting ac_try: quote all of it, if any of it seems suspicious.
5065 This means we don't have to worry about ${ or sed any more.
5066 Also, double-quote the case statement, to work around misuses via
5067 underquoting as reported by Ralf Wildenhues in
5068 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5069 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5070 undocumented and dangerous macro.

5082 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5083 since evidently some packages rely on the old, broken behavior.
5084 Problem reported by Ralf Wildenhues in
5085 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5086 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5087 pre-2006-05-26 definitions, but leave in the comments that
5088 these macros are dangerous and should not be used.
5089 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5090 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5091 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5092 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5093 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5095 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5097 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5098 the use of 'tr', since this is our only use of 'tr'.
5100 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5101 and Paul Eggert <eggert@cs.ucla.edu>
5103 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5104 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5106 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5108 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5109 the output file in the `${datarootdir}' test.
5111 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5112 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5114 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5115 mention of `datarootdir' in the input file(s), but literal
5116 `${datarootdir}' in the output file, and we haven't warned yet,
5117 then warn as well: the user may have (erroneously) used
5118 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5119 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5120 * tests/torture.at (datarootdir workaround): Extend this test.
5123 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5124 and Paul Eggert <eggert@cs.ucla.edu>
5126 * doc/autoconf.texi (autoheader Invocation): The first argument to
5127 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5128 alternatives and clear up the language a bit.
5130 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5132 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5133 ac_config_guess, ac_config_sub, ac_configure.
5134 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5135 Fix typo that prevented an unnecessary space from being removed.
5136 Problems reported by Ralf Wildenhues in:
5137 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5139 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5141 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5142 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5143 Don't use the term "thread-safe" to talk about mkdir race
5144 conditions, since the problem is more a process than a thread
5145 issue. Problem reported by Stepan Kasal in:
5146 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5147 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5148 the test for 'install' more closely. Look at MKDIR_P first.
5149 Look in the PATH, and at /opt/sfw/bin.
5150 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5151 Don't bother to try mkdir -p, since we already check mkdir --version;
5152 just look at the version number. (There's no easy way to check
5153 for race-free implementations.)
5154 * tests/tools.at (autoconf: subdirectories): Adjust to above
5155 changes, since MKDIR_P now might end in "/mkdir -p".
5157 * doc/autoconf.texi (autoheader Invocation): Mention that the
5158 first arg of AC_DEFINE_UNQUOTED must be a literal.
5159 Problem reported by Ben Pfaff in
5160 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5162 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5163 * doc/autoconf.texi (Special Chars in Variables): New section.
5164 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5165 (Installation Directory Variables): Quote $(datadir) better.
5166 (Limitations of Builtins): Describe some of eval's trickiness.
5168 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5169 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5170 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5171 in front of every arg, not just trailing args. Quote apostrophes.
5172 (_AC_EVAL_ECHO): New macro.
5173 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5174 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5176 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5177 exposed by quoting of eval argument. Put the command on line line
5179 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5180 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5181 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5182 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5183 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5184 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5185 Use eval more safely.
5186 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5187 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5189 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5190 lines, exposed by quoting of eval argument.
5192 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5193 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5195 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5196 initialization of `ac_cv_exeext', do not override it if it was
5197 already set, unless it was set to `no', for compatibility with
5198 Autoconf-2.13, and comment this.
5199 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5200 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5201 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5202 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5203 Document that this test may be overridden by setting
5206 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5208 Revert these two patches:
5210 2006-04-06 Eric Blake <ebb9@byu.net>
5211 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5212 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5215 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5216 Clean up _AC_COMPILER_EXEEXT* macros.
5217 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5218 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5219 ac_file to the name of the default output file and call
5220 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5221 initial `rm' of the candidate files...
5222 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5223 the same list in subsequent `rm' calls, and for the temporary
5224 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5225 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5226 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5227 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5228 no longer needed) by libtool. Make it a cache check.
5229 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5230 copied here by mistake.
5231 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5232 _AC_COMPILER_EXEEXT.
5233 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5234 _AC_COMPILER_OBJEXT directly.
5235 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5237 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5239 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5240 Fix description of how the buggy `sed' works.
5242 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5246 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5247 ENOLCK. Only mention `make -j' when applicable. Only raise
5248 fatal errors when `make -j' is involved. Improve error message.
5250 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5252 * doc/autoconf.texi (Here-Documents): We now know more about
5253 the variable expansion in here documents bug.
5254 Thanks to Tim Rice and Stepan Kasal.
5256 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5257 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5259 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5261 * tests/autotest.at (Multiline command from M4 expansion):
5262 No failure to be expected if the shell quotes newlines in
5263 commands in the `set -x' output. Report by Tim Rice.
5266 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5268 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5269 expansion in the here-documents used by config.status, as that
5270 runs afoul of the Korn shell version M-12/28/93d bug described in
5271 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5272 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5273 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5275 2006-05-23 Jim Meyering <jim@meyering.net>
5277 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5278 Fix typo introduced with 2006-04-02 change. It reversed the sense
5281 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5283 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5284 ac_dB slightly, to save bytes in the script.
5285 Max out at 50 lines, rather than 96; this is more likely
5286 (though not guaranteed) to avoid obscure 'sed' failures.
5288 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5290 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5291 `tr -d -' as bad option argument. Work around this by deleting
5292 an unrelated character.
5293 Report by Tim Rice <tim@multitalents.net>.
5295 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5296 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5297 Stepan Kasal <kasal@ucw.cz>
5299 * doc/autoconf.texi (Particular Programs): Do not promise that
5300 we always prefer the GNU version of the program, and that we
5301 search according to PATH; both rules can have exceptions.
5302 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5303 AC_PROG_SED. Move descriptions of limitations
5304 to the Limitations of Usual Tools section.
5305 (Limitations of Usual Tools) <sed>: Mention script length
5306 limitations with Solaris /usr/ucb/sed.
5307 <grep>: Fix wording for empty alternative. Mention that -c and
5308 -l should not be combined, and that -E and -F should not be

5314 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5315 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5317 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5319 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5320 AC_DEFINE is now passed to m4_pattern_allow.
5321 * NEWS: Mention that; likewise for AC_SUBST.
5322 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5323 the parameter to m4_pattern_allow.
5324 * tests/tools.at: Add a check for that.
5326 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5328 * lib/autoconf/status.m4: Fix typos.
5330 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5332 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5333 only the files that this macro generates.
5335 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5337 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5338 the HP-UX sed limitation of 99 commands, labels do not count.
5339 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5341 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5343 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5345 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5346 Import the following fix from coreutils:
5348 2006-01-13 Jim Meyering <jim@meyering.net>
5350 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5351 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5352 not double-quote uses of that variable, to accommodate the rare
5353 case in which getmntent is available in none of the libraries
5354 checked. This happens at least on FreeBSD 5.0.
5356 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5358 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5359 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5360 some other programs unwisely rely on these undocumented vars.
5361 But put in warning comments about them.
5362 Problem reported by Ralf Wildenhues in
5363 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5364 * NEWS: Document that these variables are intended to go away.
5366 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5368 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5369 and set the language to C++ (analogous to the equivalent Fortran
5372 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5373 * doc/autoconf.texi (C++ Compiler): Document it.
5374 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5377 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5379 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5380 that caused config.status to generate 100-command sed scripts; the
5381 portable limit is 99.
5383 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5385 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5386 variable `ac_d' instead of `d' to avoid infringing namespace.
5387 Report by Ralf Menzel.
5389 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5391 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5392 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5393 * tests/tools.at (autoconf: subdirectories): New test, taken from
5394 the corresponding problem report by Ralf Wildenhues in:
5395 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5397 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5398 Quote some uses of shell variables if they might suffer unexpected
5399 globbing. This doesn't fix all instances of quoting problems that
5400 I found, just the easy ones that look safe.
5401 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5402 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5403 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5404 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5405 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

5412 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5414 * bin/autoreconf.in ($help): Reword according to the manual.
5415 Suggested by Olly Betts.
5417 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5418 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5420 * bin/autoreconf.in: Pass the directory argument to
5421 `require_configure_ac'. Fix comment.
5422 * tests/torture.at (Configuring subdirectories): Expose this.
5423 Reported by Olly Betts.
5425 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5427 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5428 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5429 Automake as follows:
5431 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5432 `$configure_in' instead of `configure.in', to preserve
5433 directory component.
5435 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5437 * config/config.guess, config/config.sub, config/texinfo.tex,
5438 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5440 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5442 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5443 test for C99 conformance; (bool) 0.5 is an integer constant
5444 expression, but (bool) -0.5 is not. Problem reported by Fedor
5445 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5447 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5449 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5450 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5451 Warn about obsolete install-sh files. Remove stray sentence
5452 fragment and fix cross reference.
5453 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5454 install -d; this undoes the 2006-05-10 change.
5455 (MKDIR_P): Mark with AN_MAKEVAR.
5456 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5457 that we don't require $INSTALL to be thread-safe. Move comments
5458 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5459 of AC_PROG_INSTALL. Output a message saying that we're checking
5460 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5461 MKDIR_P instead of AC_SUBST.
5462 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5463 Special magic for MKDIR_P, too.
5464 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5466 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5468 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5470 Sync from Automake, as follows:
5472 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5473 * config/install-sh: Initialize IFS, so field splitting isn't
5475 * config/mkinstalldirs: Likewise.
5476 * config/missing: Remove superfluous quotes. Replace all uses of
5477 `[' by `test', for consistency, and for..
5478 * config/missing (sed_minuso, sed_output): New variables.
5479 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5480 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5481 Fixes `missing' to detect `--output' for help2man. Fixes
5482 PR automake/483. Report by Dennis J. Linse.
5483 (autom4te): Document in `missing --help'.
5485 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5487 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5488 * config/install-sh: Don't use 'path' to talk about file names,
5489 as per GNU coding standards. Close a race condition reported by Ralf
5490 Wildenhues and Stepan Kasal. There is still a race condition
5491 on hosts that predate Posix 1003.1-1992, but we can't help this.
5492 Don't mishandle weird characters like space on pre-Posix hosts.
5493 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5494 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5495 AC_PROG_MKDIR_P from AS_MKDIR_P.
5496 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5497 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5498 earlier editions are not (including Automake 1.8.3).
5499 Do not suggest mkinstalldirs for thread-safety.
5500 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5501 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5502 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5503 presence of special characters and race conditions.
5504 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5505 in Autoconf's name space.
5507 2006-05-10 Bruno Haible <bruno@clisp.org>
5508 and Paul Eggert <eggert@cs.ucla.edu>
5510 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5511 from Automake with minor changes.
5512 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5514 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5516 * config/install-sh: Update to Automake CVS version, as follows:
5517 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5518 * lib/install-sh: Simplify the expr implementation of dirname.
5519 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5520 * lib/install-sh: Handle --, and diagnose unknown options.
5522 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5524 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5525 `./autom4te' to create `./testsuite', since the `all' target
5526 will ensure its presence, but `installcheck' should not create
5527 the uninstalled wrappers.
5529 * tests/torture.at (Unusual Automake input files): Skip if we
5530 detect automake < 1.8.
5532 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5534 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5535 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5536 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5539 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5541 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5542 munge (multiple) white space and other oddities.
5543 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5544 single quotes in variable assignment.
5545 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5546 and similar failures by adding multiple spaces, tabs, and other
5548 Report and different test suggested by Francesco Romani
5549 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5551 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5552 single quotes, we only need to search for single quotes; this
5553 both simplifies the search pattern, and makes us less
5554 susceptible to `echo' variations for arguments not containing
5556 (_AC_ARG_VAR_VALIDATE): Likewise.
5558 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5560 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5561 `$*' and IFS concatenation issue with traditional shells and
5562 bash-2.04. Report by Seanster@Seanster.com.
5564 2006-05-03 Bruno Haible <bruno@clisp.org>
5566 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5567 precisely which Mac OS X versions have the od problem.
5569 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5571 * doc/autoconf.texi: Use @option systematically.
5573 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5574 and Bruno Haible <bruno@clisp.org>
5576 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5578 (Integer Overflow): Mention the special case of integer division
5581 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5583 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5584 traditional shells like the Solaris one that do not use the
5585 first IFS character for assembling `$*'.
5586 Prompted by a related report from autoconf_bug@nro.ca.
5588 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5589 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5591 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5592 Mention more problems with the -e option.
5594 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5597 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5599 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5600 in URLs to improve DVI formatted output (requires texinfo 4.6).
5601 (System Services, Systemology, Shellology): Likewise.
5602 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5605 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5607 (Runtime): Fix macro argument names to match description:
5608 `action-if-found' -> `action-if-true' and similarly.
5609 (Obsolete Macros): Likewise.
5610 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5611 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5612 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5614 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5616 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5619 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

5646 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5647 since as_me isn't set yet.
5649 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5651 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5652 a few minor bugs in this area.
5654 * doc/autoconf.texi (Programming in M4sh): Comment out the
5655 documentation of AS_BASENAME, for now.
5656 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5657 (Limitations of Builtins) <basename>: Do not refer to
5659 * bin/autoconf.as (me): Don't use AS_BASENAME.
5660 (dir): Remove the unused variable.
5661 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5662 AS_DETECT_REQUIRED. All uses changed.

5685 with more accuracy and detail.
5687 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5689 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5690 Archive is not officially `GNU' any more. Update URL.
5691 (Defining Directories): Likewise
5692 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5694 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5696 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5697 newline from the `trap' code to finish `config.log'; the NetBSD
5698 /bin/sh resets the exit status after an empty command, as
5699 documented in doc/autoconf.texi.
5700 Reported by Dalibor Topic <robilad@kaffe.org>.
5702 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5704 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5705 Suggested by Bruno Haible.
5707 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5709 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5710 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5711 Instead, just list the shells that we know work.
5712 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5713 changed. Be more cautious about the _cv_ variable.
5714 * tests/tools.at (Syntax of the shell scripts): Check the
5715 _cv_ variable once, at first, to avoid an internal autoconf error
5716 when sh -n does not work.
5718 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5720 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5722 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5724 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5725 use ">&-" since we're only 99.999% sure that this is portable,
5726 and since the MinGW bug is fixed in a different way.
5727 * lib/autotest/general.m4 (AT_INIT): Likewise.
5729 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5731 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5732 before opening config.log, to avoid hitting a bug on MinGW.
5734 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5736 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5737 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5738 This works around a MinGW bug reported by Eric Paire.
5739 Make sure that all writes to the log file append to it,
5740 rather than possibly losing data.
5741 * lib/autotest/general.m4 (AT_INIT): Likewise.
5743 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5745 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5748 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5752 * configure.ac (AC_INIT): Bump to 2.59d.
5754 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5758 * Makefile.maint (news-date-check): Do not require a leading `*'
5759 before the release date in NEWS.
5761 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5762 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5764 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5765 the instantiated file do not contain the string 'datarootdir'
5766 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5767 @mandir@, replace the reference '${datarootdir}' by the value.
5768 * tests/torture.at (datarootdir workaround): New test.
5769 * NEWS: Advertise this temporary fixup.
5770 Based on a patch by Bruno Haible, reported and analyzed by
5771 Paul Eggert and Noah Misch.
5773 2006-04-12 Eric Blake <ebb9@byu.net>
5775 * tests/autotest.at (Debugging a failed test): Fix comment.
5777 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5779 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5780 all the changes since 2006-04-07.
5782 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5784 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5785 succeeded, but `ln -s file dir' failed, take care to remove the
5786 leftover target before the next test, to prevent its spurious
5787 failure; also make sure `ln file dir' works before selecting it.
5788 Thanks to Keith Marshall for pointing this out.
5791 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5792 assignments in `at_debug_args', so that we put them correctly
5793 in the `run' script.
5794 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5795 Reported by Eric Blake.
5797 2006-04-11 Eric Blake <ebb9@byu.net>
5799 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5800 top-level tests after micro-suite has been run. Used in...
5801 (Debugging a successful test, Debugging script and environment),
5802 (Debugging a failed test): ...these new tests. The first of these
5804 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5805 macro, split out from...
5806 (AT_INIT): ...here, so that using -d also generates a run script.
5807 Document that -d inhibits top-level logging.
5808 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5809 inhibits top-level logging; debug scripts are created.
5811 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5813 * tests/autotest.at (Empty test, Empty check): New test to check it.
5815 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5818 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5820 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5821 the files if a problem appears. Make the empty *.at files
5822 read-only, too. Proposed by Ralf Wildenhues.
5824 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5826 * config/Makefile.am: Add comment to force updated Makefile.in.
5828 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5829 space only patch to this file, this patch causes the Makefile.in
5830 files that include freeze.mk to be updated, and thus have a
5831 newer time stamp again, which in turn makes a pristine CVS
5832 checkout have correct time stamps.
5834 * Makefile.maint (cvs-sv): New macro, to be used..
5835 (config.guess-url_prefix, config.sub-url_prefix)
5836 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5837 point to CVS text checkout of Gnulib files.
5838 (copyright-check): Bump current year.
5839 (announcement): Do not hard-wire `./announce-gen'.
5840 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5842 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5844 (wget_files): Update config.guess, config.sub, texinfo.tex by
5845 `wget-update', now that their URLs work again.
5847 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5849 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5850 Problem noted by Paul D. Smith.
5852 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5854 * doc/autoconf.texi: Remove unused words from word list.
5855 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5856 .x-sc_trailing_space: New files.
5858 * doc/standards.texi: Sync from gnulib.
5860 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5861 `LIBOBJDIR' as experimental.
5863 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5864 with a target directory; it's internally implemented as `cp'
5865 anyway, but since Autoconf advertises the possibility to use
5866 a target directory when LN_S is `ln -s', we need to find out.
5867 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5868 analyzed by Keith Marshall <keith.marshall@total.com>.
5872 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5874 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5875 confdefs.h as-is. In general, if it has backslash-newline or the
5876 like, then it doesn't work either to sort or to remove empty
5879 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5881 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5883 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5885 * lib/autom4te.in (Automake-preselections): Preselect
5888 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5890 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5891 apostrophe within a single-quoted string, as this is the usual
5892 tradition and is easier to read than '"'"'. Don't rely on the
5893 shell treating "$/" like '$/'. Use a more-consistent indenting
5896 2006-04-09 Eric Blake <ebb9@byu.net>
5898 * tests/autotest.at (Backquote command substitution),
5899 (Multiline backquote command substitution): Remove mistaken
5900 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5902 (Parenthetical command substitution, Multiline parenthetical
5903 command substitution): here.
5905 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

5938 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5939 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5940 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

5980 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5982 Revert the patch from 2006-04-01 and only improve
5983 _AS_DETECT_BETTER_SHELL:
5985 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5986 skip nonexistent directories.
5987 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5988 only shell candidates which exist.
5989 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5990 * lib/autotest/general.m4 (AT_INIT): No need to give three
5991 parameters to _AS_PATH_WALK.
5993 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5994 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5996 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5997 distinguish m4sugar macros.
5998 * tests/tools.at (autoupdating with aclocal and m4_include):
5999 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6000 test case by Noah Misch <noah@cs.caltech.edu>.
6002 2006-04-07 Stepan Kasal <kasal@ucw.cz>

6005 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6007 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6008 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6011 2006-04-07 Eric Blake <ebb9@byu.net>
6013 * doc/autoconf.texi (Programming in M4sh): Document that
6014 AS_MKDIR_P exits the script on failure.
6015 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6017 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6019 * config/elisp-comp, config/install-sh, config/mdate-sh,
6020 config/missing, config/mkinstalldirs: Sync from Automake.

6035 Paul Eggert <eggert@cs.ucla.edu>,
6036 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6038 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6039 whether `set' quotes correctly: redirect stderr of the tested
6040 `set', and use a subshell, for Ultrix; use `sed' instead of
6041 `grep' for zsh `set' which may write binary output; match only
6042 at the beginning of a line, to avoid false positives.
6043 In order to avoid false positives by unrelated variables with
6044 multiline content, put the dump algorithm in a subshell and
6045 unset all variables containing newlines (except some which are
6046 special to the shell). Warn about cache variables that are
6049 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6092 ac_config_<foo>s again, sometimes normalized, sometimes not.
6093 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6094 (AC_CONFIG_COMMANDS): Do not do so here.
6095 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6096 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6097 2005-07-25 rewrite. Noticed by Noah Misch.
6099 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6100 _AC_PRESERVE_HELP_ORDER, ...
6101 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6103 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6104 inside m4_expand_once; it is redundant.
6106 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6107 for --help from Cygnus `configure.'
6109 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6122 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6123 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6124 * doc/autoconf.texi (Help Formatting): New node.
6125 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6127 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6129 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6130 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6131 lib/autoconf/types.m4, lib/autotest/general.m4,
6132 tests/mktests.sh, tests/torture.at: White space cleanup:
6133 remove some SPACE before TAB, or add quoting ('' or @&t@).
6135 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6137 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6139 2006-04-05 Eric Blake <ebb9@byu.net>
6141 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6142 empty test suite works.

6151 normalizing it, consistent it with previous releases.
6152 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6154 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6156 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6157 Use simplified args that Eric Blake originally suggested.
6159 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6161 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6162 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6163 Use 'comm' rather than N instances of grep; this also fixes a bug
6164 whereby substrings were incorrectly matched, causing us to not
6165 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6166 (exclude_list): Exclude empty macros.
6167 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

6180 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6182 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6183 report request when we have no AC_PACKAGE_BUGREPORT.
6185 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6189 * tests/mktests.sh: Update copyright year in the header of the
6192 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6193 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6194 typedef'ed restricted pointer, to catch a compiler bug on
6195 HP-UX 11.x, and fix warnings so it passes with -Werror.

6207 2006-04-03 Noah Misch <noah@cs.caltech.edu>
6209 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
6211 2006-04-03 Eric Blake <ebb9@byu.net>
6213 * THANKS: Add myself.
6215 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6217 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6218 to log, point to testsuite output tree.
6220 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
6222 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

7039 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7040 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7041 by the function rather than ignoring it.
7042 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7043 comparing its address. Intel's interprocedural optimization was
7044 outsmarting the old heuristic. Problem reported by

7062 Stepan Kasal <kasal@ucw.cz>
7064 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7065 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7066 make its content writable before removing it. Remove an errorneous

7093 suggested by Ben Elliston. Handle weird characters correctly.
7095 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7097 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7098 calls, so that the final expansion of this macro is shorter.
7099 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7100 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7101 the cleanup there. Use AS_VAR_* macros, to be more general.
7102 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7104 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7106 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7127 in the example. Reported by Bruno Haible.
7128 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7129 "if $undefined_var;" succeeds with my shell.
7131 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7132 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7133 but change the m4_divert_text to m4_divert_once.

7151 first header appears, define AH_HEADER.
7152 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7153 Update limitations about when to call AC_CONFIG_HEADERS.
7154 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7155 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7156 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7157 ``Configuration Actions''; fix their index entries.
7159 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7160 options correctly. Process N-M as M-N if M is smaller than N.
7161 Process ranges correctly so that N-N will run only N.
7162 Sort and uniquify the tests that will be run. If there is more
7163 than one test, reinsert the banners for the tests.
7164 * tests/autotest.at (Keywords): Unmark XFAIL.

7169 before passing the macro name to AH_TEMPLATE.
7171 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7172 now opens log after option processing; in particular, --version
7173 and --help do not touch config.log.

7190 Prepend to LIBS, not append, in examples.
7192 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7194 When building in place, set srcdir="."; suggested by Tim Van Holder.
7196 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7197 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7198 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7199 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7200 does not mean "no --srcdir option".
7202 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7204 * tests/autoscan.at (autoscan): New file.
7205 * tests/suite.at: Use it.

7229 * Makefile.maint: Update from Bison.
7231 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7232 "<tab>" in comment, so that the point is understandable.
7234 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7236 Rewrite substantial part of lib/autoconf/status.m4.
7237 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7238 and CONFIG_COMMANDS are not processed in four separate loops.
7239 Instead, there is one main loop. This alows that the common code
7240 is expanded only once, thus config.status (and configure) is smaller.
7242 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7243 the AC_LIST_FILES and cousins macros are no longer used.
7245 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7246 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7247 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7248 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7249 contain the initialization, nor the for loop, nor the associated
7250 commands; all these go to ...
7251 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7252 _AC_OUTPUT_CONFIG_STATUS.
7253 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7254 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7255 (_AC_OUTPUT_FILE): The creation of the sed script ...
7256 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7257 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7258 _AC_OUTPUT_MAIN_LOOP.
7259 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7260 _AC_CONFIG_COMMANDS): Use ...
7261 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7262 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7263 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7264 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7265 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7266 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7268 (_AC_CONFIG_UNIQUE): Update.
7269 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7270 Replaced by this ...
7271 (_AC_LIST_TAGS): ... new common macro.
7272 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7273 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7274 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7275 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7276 this didn't belong to the `config commands' section.
7277 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7278 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7279 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7280 to the `config commands' section either.
7281 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7282 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7284 ... and many changes to the comments nearby.
7286 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7287 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7288 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7289 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7290 (#define header templates): The comment at the top of the generated
7291 header now includes the name(s) of the source file(s).
7293 Several unrelated small changes:
7295 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7296 parameter to AC_DIAGNOSE.
7297 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7298 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7299 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7300 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7302 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7303 in AC_OUTPUT doesn't double-quote it either.
7304 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7307 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7309 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7310 versions of Portland Group compiler produce single- and double-quoted
7311 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7312 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7314 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7316 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7317 This is a corrected version of yesterday's patch.
7319 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7321 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

7325 ac_cv_build_alias to ac_build_alias.
7326 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7328 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7329 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7330 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7331 (AC_ARG_VAR): ... here.
7332 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7335 Keep a list of all precious variables and process them with one simple
7336 for loop, instead of expanding all commands, or, OTOH, complicated
7337 processing of output of "set".
7338 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7339 variable names in new macro...
7340 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7341 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7342 a loop to assign all ac_env_* and ac_cv_env_* variables.
7343 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7345 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7346 its value to shell variable ac_precious_vars and call
7347 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7348 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7349 _AC_ARG_VAR_VALIDATE.
7351 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

7379 Fix cases when the varsions of Autoconf and Autotest don't match.
7380 Reported by Noah Misch.
7381 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7382 at_top_builddir, for compatibility with older autotest.
7383 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7384 is not set, use at_top_builddir, for compatibility with older
7385 versions of autoconf.
7387 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7389 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7390 Problem reported by Patrick Welche.
7392 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7394 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7395 sed substitution command, so that we allow | in program prefixes
7396 and program suffixes. (& is a problem anyway; we're not fixing
7398 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7399 configure_input, top_builddir, srcdir, etc.
7400 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7401 PATH_SEPARATOR in AUTOTEST_PATH.
7403 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

7411 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7412 directories with weird names. Apparently some people like living
7413 on the edge. However, improve the test that "pwd" actually does
7414 report a name for the working directory.

7417 2005-07-01 Stepan Kasal <kasal@ucw.cz>

7434 document to output the default config_* lists to config.status.
7435 Don't recognize option --file, if the functionality is not there.
7436 Likewise for --header; moreover, recognize --he and --h as shortcuts
7437 for --help in that case.
7439 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7440 matches the order of execution. No code changed.

7464 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7465 the directory specific variables; but don't call it for configure_input.
7467 2005-06-28 Derek Price <derek@ximbiot.com>
7469 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7472 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7474 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7475 directory have inherent problems with special characters like spaces,
7476 due to limitations in Make syntax. Problem reported by Alexandre
7478 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7494 because we really don't support spaces and suchlike in dir names.
7495 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7496 Don't worry about backslashes in srcdir; it can't happen now.

7540 * doc/autoconf.texi:
7541 Don't mention Solaris versions so much, if a
7542 problem is common to all extant versions of Solaris. Say "SunOS
7543 4" instead of "SunOS" for SunOS 4.
7544 (awk): Mention more of the limitations of traditional Awk.
7545 (cat): Don't talk about cat -v.

7589 Problem reported by Ralf Menzel.
7591 2005-06-08 Derek Price <derek@ximbiot.com>
7593 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7594 renaming them since they are about to be redefined anyhow.
7596 2005-06-08 Derek Price <derek@ximbiot.com>
7598 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7599 redefined M4 macros to this node. Document m4_include & m4_sinclude.

7611 might get inadvertently cut-and-pasted into user code.
7612 Remove example of autom4te usage that doesn't seem to work now.
7613 Use modern AC_INIT (except when the example is meant to be

7628 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7629 Tru64 ksh pattern matching bug. Reported against Libtool by
7630 Albert Chin <libtool@mlists.thewrittenword.com> and
7631 Nicolas Joly <njoly@pasteur.fr>.

7635 m4_cdr of one-member list was [[]] (one-member list containing an
7636 empty string) instead of [] (an empty list. Callers were skewed to
7637 match this misbehaviour. As a consequence of this:
7638 - m4_foreach([x], [], [foo]) expanded to `foo', while
7639 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7640 This bug has been fixed:
7642 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7643 expand to an empty string; print error msg if called without
7645 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7646 misbehaviour; handle [] and [[]] correctly.
7648 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7650 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7651 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7652 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7654 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7656 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7657 swallow records with more than 99 fields.
7658 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7659 parse the long line.
7661 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7663 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7664 swallow literals longer than 399. Reported by Ralf Wildenhues.
7665 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7666 to workaround this limitation.
7668 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7670 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7671 to gfortran, and make these the first two compiler names
7672 checked (following the general autoconf preference for gcc).
7674 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7676 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7677 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7678 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7680 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7682 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7683 expression of unbounded size when processing the --list
7684 option. This runs afoul of a limit of 399 bytes per regular
7685 expression on AIX. Problem reported by Ralf Wildenhues.
7687 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7689 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7690 * doc/autoconf.texi (Particular Headers): Reword example
7691 for multiline stdbool replacement.
7692 (Setting Output Variables): Reword text a bit. Don't
7693 give all the details about |#_!!_#|.
7694 Reword description of line replacement.
7696 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7698 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7699 now contain newlines, and substituted files must be referenced on
7700 a line alone; the sed scripts to substitute them are now very
7702 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7703 commands can be put in a sed script portably.
7704 * doc/autoconf.texi (Setting Output Variables): Document above
7705 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7706 use of multiline substitution.
7707 * tests/torture.at: No longer expect substitution of newline to fail.
7709 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7711 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
7712 From Ralf Menzel (trivial change).
7714 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7716 * tests/local.at: Don't attempt to check for negated character
7717 classes in shell scripts. The test was too brittle.
7719 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7721 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7722 * doc/autoconf.texi (Limitations of Builtins): Document this
7725 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7727 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7728 common code; used in many places in the tree.
7729 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7730 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7732 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7734 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7735 messages when ac_unique_file is not found.
7736 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7737 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7738 commands, for consistency with AC_MSG_ERROR and such.
7740 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7742 * bin/Makefile.am: Merge the two rules for creating scripts.
7744 2005-05-23 Stepan Kasal <kasal@ucw.cz>
7746 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
7747 obsolete; it was never documented.
7748 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7750 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7752 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7753 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7754 (ac_top_builddir): ... this ...
7755 (ac_top_build_prefix): ... to this; the old name is also kept, for
7756 backward compatibility.
7757 (ac_top_builddir_sub): New variable, without the trailing slash,
7759 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7760 * doc/autoconf.texi (Configuration Actions): Rename
7761 ac_top_builddir to ac_top_build_prefix.
7762 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7763 at_top_builddir to at_top_build_prefix.
7764 * lib/autotest/general.m4 (AT_INIT): Likewise.
7766 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7768 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7771 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7773 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7774 argument to m4_foreach. I guess it was necessary in the past,
7775 but I think it's a no-op now.
7777 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7779 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7780 ``cat <<_ACEOF'' commands to one.
7781 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7782 * lib/autoconf/status.m4: On various places, use expr instead of
7784 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7785 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7786 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7788 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7789 the wrong patterns between ``case'' and ``esac.'' The previous
7790 code had false positives.
7792 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7794 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

7837 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7839 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7841 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7842 enough arguments, similarly as in m4_bpatsubsts.
7844 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7846 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7849 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7851 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7852 for absolute directory names in one loop.
7853 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7854 abbreviations of --version and --debug.
7856 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7858 * doc/autoconf.texi (Autoconf Language): Be more precise about
7859 quoting rules. Problems noted by Stepan Kasal.
7860 Also, throughout this document, be more careful about white space.
7861 "blank", "white space", and "space" all have different meanings
7862 and we should be careful to say what we mean.
7864 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7866 Fix C++ related problems reported by Werner Lemberg.
7867 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7868 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7869 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7870 avoid problems with C++ and throw.
7871 * tests/compile.at: .cpp, not .cc.
7873 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7875 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7877 * doc/autoconf.texi (Generic Functions): Typos.
7879 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7881 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7882 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7883 set by latest automake.
7885 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7887 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7888 outputs 0 on GNU/Linux these days.
7890 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7892 * doc/autoconf.texi (Autoconf Language): Add more description
7893 about quoting heuristics.
7894 (Limitations of Builtins): Describe "set -" problems.
7896 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7898 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7901 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7902 by AC_DEFINE; it was a mistake.
7903 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7905 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7907 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7909 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7911 * doc/autoconf.texi (External Software): Quadrigraphs are not
7912 processed correctly in AS_HELP_STRING; avoid this in the examples.
7913 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7914 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7915 comment and reduce m4_default([foo], []) to [foo].
7916 (m4_strip): Update the explanation.
7918 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7920 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7921 Remove core.conftest.* too; it's generated by Tru64 5.1.
7922 Problem reported by Jennis Pruett.
7923 * lib/autoconf/functions.m4
7924 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7925 Don't bother to remove core files; AC_RUN_IFELSE should do that
7928 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7930 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7932 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7934 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7935 Report from Horst Wente.
7937 2005-04-15 Stepan Kasal <kasal@ucw.cz>
7939 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
7942 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7944 * doc/autoconf.texi (External Software, Package Options): Add
7945 examples showing how to implement --with-* and --enable-* options.
7947 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7949 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7950 as well as configure.in. Problem reported by Gregorio Guidi.
7952 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7954 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7955 pattern for alloca snippet.
7957 2005-04-04 Stepan Kasal <kasal@ucw.cz>
7959 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

7963 * doc/autoconf.texi (Generic Programs): Fix a typo.
7965 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
7967 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7968 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7970 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7972 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7973 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7974 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7975 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7976 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7978 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7980 * NEWS: The configure command now warns you if you attempt to use
7981 a directory whose name contains a special character like space,
7983 * doc/autoconf.texi (Installation Directory Variables): Allow
7984 "," in file names. Do not use \@; it's not a portable regexp.
7985 * bin/Makefile.am (edit): Likewise.
7986 * lib/Makefile.am (edit): Likewise.
7987 * tests/Makefile.am (edit): Likewise.
7988 * tests/semantics.at: Likewise.
7989 * tests/torture.at: Likewise.
7990 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7991 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7992 * doc/autoconf.texi (File System Conventions): Warn about
7993 unportable file names.
7994 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7996 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7997 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7998 ac_pwd, and quote srcdir.
7999 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8001 * doc/autoconf.texi: Fix some systematic formatting problems.
8002 ".)" needs a following @: if not at the end of a sentence, and
8003 similarly for "!)". "etc." should be preceded by a comma.
8004 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8006 2005-03-22 Bruno Haible <bruno@clisp.org>
8008 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8009 argument is often called 'build-aux'.
8011 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8013 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8014 macro AC_TRY_LINK is obsolete.
8015 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8018 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8020 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8021 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8022 from a Common Lisp's `cl'.
8023 (AC_PROG_CXX): Behave according to the documentation: don't
8024 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8025 make the variable CCC precious; use `cl.exe', not `cl'.
8027 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8028 Alexandre Duret-Lutz <adl@gnu.org>
8030 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8031 /dev/null, as "configure" shouldn't read stdin, and this insulates
8032 us from problems (e.g., when testing for "cl"). Also, do this
8033 redirection before invoking "hostname" or "uname", and keep the
8034 original input stream available via...
8035 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8036 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8037 bother with "</dev/null" since it's now done at the top of
8039 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8040 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8041 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8042 * doc/autoconf.texi (File Descriptor Macros): New section.
8043 (Printing Messages): Mention it.
8044 * tests/base.at (Input/Output): New test.
8046 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8048 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8049 newline if neither \c nor -n work, as that would output two
8050 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8052 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8054 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8055 This causes that any required macros inside will get before the if.
8056 * doc/autoconf.texi (autom4te.cache): A typo.
8058 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8060 Undo previous change, except keep the change to
8061 lib/autoconf/programs.m4 that replaced grep with shell
8062 pattern-matching. This is because net-snmp configure reads stdin.
8063 Reported by Noah Misch.
8065 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8067 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8068 from /dev/null, as "configure" shouldn't read stdin, and this
8069 insulates us from problems (e.g., when testing for "cl").
8070 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8071 before invoking "hostname" or "uname".
8072 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8073 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8074 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8075 "</dev/null" since it's now done at the top of 'configure'.
8076 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8077 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8078 Also, replace grep with shell pattern-matching, to save a process.
8080 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8082 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,

8246 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8247 Update the long comment explaining it.
8249 m4_require no longer writes an ``is required by'' line to the
8250 execution stack. It contains only one bit of non-redundant
8251 information: that the macro was required, not called. And even
8252 this bit is useless in most situations: have you ever met a macro
8253 which both calls and requires the same macro?

8303 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8304 Warn about newline stripping in `` and $(). Update Solaris
8306 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8307 X insulates us from future changes to Posix.

8361 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8362 stored in _m4_divert_diversion or _m4_divert_dump.
8363 (m4_divert_pop): When the parameter is given, compare the symbolic
8364 name with the last diversion pushed on the stack. Previously, the
8365 current diversion was compared with the numeric value of the
8366 diversion given as the parameter.
8367 (m4_require): If the macro hasn't been expanded yet, call ...
8368 (_m4_require_call): this new macro.

8647 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8649 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
8650 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8651 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8652 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

8673 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8675 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8676 "char c = '\200';" rather than "char c = 0x80;" as the
8677 latter doesn't conform to the strict C standard due to
8678 overflow on signed char hosts.
8680 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8681 to -qlanglvl=ansi. We don't want to disable extensions.
8683 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8685 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

8737 simplify the examples and improve their quoting.
8739 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8741 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8742 the $1_found variable, don't test whether the file is executable;

8794 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8795 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8796 (trivial change). Problem and patch reported by Andrew Church in:

8826 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8827 texinfo.tex for now (done by hand now).
8828 * Makefile.maint (wget_files, cvs_files):
8829 Remove ansi2knr.c; nobody uses it.
8830 (ansi2knr.c-url_prefix): Remove.
8831 (cvs-update): Fix test for failure. I don't know why it ever
8834 * doc/autoconf.texi: Update URLs, some of which went stale.

8837 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8838 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8840 * config/config.guess, config/config.sub, config/elisp-comp,
8841 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8842 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8850 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8851 tests/tools.at, tests/torture.at:
8852 Use "file name" rather than "filename" or "path",
8853 to be consistent with the terminology of the GNU coding standards.
8855 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8857 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

8862 More fixes to support spaces in the name of the build directory.
8863 This isn't a complete fix but it's an improvement.
8865 * bin/autoconf.as (autom4te_options): New var.
8866 Use it instead of appending to AUTOM4TE, so that we can allow
8867 spaces in the build directory's absolute name.
8868 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8869 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

8882 * doc/autoconf.texi (Function Portability): Document isinf and
8883 and isnan. From a suggestion by Kevin Ryde.
8885 * lib/Autom4te/General.pm (END): Return correct exit status even
8886 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8888 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8890 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8891 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8892 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

8900 * lib/autom4te.in (Automake-preselections): Preselect
8901 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8903 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8905 * lib/autom4te.in (Automake-preselections): Preselect
8906 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8909 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8911 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

8918 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8919 with pdksh, too. Problem reported by Patrick Welche via
8921 * doc/autoconf.texi (Shellology): Note that set -o posix is
8922 useful for pkdsh, too.
8924 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8926 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8927 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8928 Don't fail if ENV or BASH_ENV is readonly.
8929 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8930 etc. are read only. Problem reported by Ludovic Courtes.
8932 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8934 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

8938 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8940 * doc/autoconf.texi (File System Conventions): Warn about
8941 names like "aux". Problem reported by Eric Blake.
8943 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8944 by zero instead of array size, so that we can use any arithmetic
8945 constant expression (instead of requiring an integer constant
8946 expression). This allows us to test expressions like DBL_MAX <
8947 LDBL_MAX, which didn't conform to the C standard using the old
8949 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8950 now that we can do floating-point tests at compile time.
8952 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8954 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8955 and LDBL_EPSILON, as the resulting expression isn't an
8956 integer constant expression and violates the C standard.
8957 Problem reported by Nelson H. F. Beebe. Also, check
8958 for "L" suffix, and check that long double doesn't have
8959 worse range or precision than double, that mixed-mode
8960 arithmetic doesn't generate a diagnostic, that double
8961 constants fit in long double.
8963 2004-06-03 Kevin Ryde <user42@zip.com.au>
8965 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8966 malloc(0) and realloc(NULL,size).

8971 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8973 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8974 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8977 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8979 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND

8990 change). Patch reported by Ralf Wildenhues in
8991 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8993 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8994 function F exists if the compiler and linker let you compile an
8995 expression like (F != 0). Recent versions of GCC optimize away
8996 the reference to F in that case, since every function address must
8997 be nonzero, so the link succeeds even if F does not exist.
8998 Problem reported by Manu in
8999 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9001 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9002 "Unix". Many uses changed.

9017 note pessimistic assumption when cross compiling.
9019 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9021 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9022 (until 2004) invoked subcommands with sh -e, contra POSIX.
9023 Reported by Kevin Ryde.
9025 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9027 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9028 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9029 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9030 `test -f " /usr/bin/grep"', which _always_ failed.
9031 (AC_PROG_SED): Ditto bogus PATH fix.
9032 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9033 requires that grep correctly supports _multiple_ `-e' options, rather
9034 than stating only that grep should accept `-e'.
9036 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9038 Port to C99, which requires that 'exit' be declared.
9040 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9041 to ensure that stdlib.h is included.
9042 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9043 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9044 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9045 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9046 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9047 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9048 when using 'exit' in a test; C99 requires that 'exit' be declared.
9050 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9052 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9053 now prefers 'grep' implementations that accept -e.
9054 (Limitations of Usual Tools): Describe problems of traditional
9055 egrep and fgrep with long input lines, and of traditional grep
9057 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9058 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9059 All callers changed. Append /usr/xpg4/bin to the PATH, for
9061 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9062 the user with complaints about multiple -e options.
9063 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9064 Define it with AC_PROG_GREP.
9065 * configure.ac (AC_PROG_GREP): Add.
9066 * lib/freeze.mk (GREP): New macro.
9068 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9070 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9071 a possible candidate only after all others fail, rather than
9072 consulting it first. This improves backward compatibility by
9073 better reflecting the way shell selection occurred in previous
9074 versions of Autoconf, and should help to avoid triggering latent
9075 problems in other packages, such as the one in Automake where zsh
9076 is not handled robustly:
9077 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9078 Although it is not Autoconf's responsibility to work around
9079 problems in Automake, it nevertheless makes sense to avoid
9080 introducing unnecessary incompatibilites.

9083 Gary V. Vaughan <gary@gnu.org>
9085 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess

9089 nested we are in this macro. Break out of all 3 nested loops if
9090 ac_path_TOOL_found is set.
9092 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9094 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9095 of the _AS_PATH_WALK loop too if GNU flavor is found.
9097 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9099 * doc/autoconf.texi (Limitations of Make): Update documentation
9100 for `$<'. New entry `Long lines', based on a report from Simon
9101 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9102 paragraph about DJGPP, based on a mail from Richard Dawe.
9104 2004-04-20 Paul Eggert <eggert@twinsun.com>
9106 * tests/c.at (C keywords): Don't assume that GCC supports
9107 "restrict" and "inline", as sufficiently-old GCC versions do not
9108 (also, GCC configured to be in pedantic C89 mode does not).
9109 Problem reported by Sumit Pandya in:
9110 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9112 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9113 consider -g to work if it generates warnings when plain compiles
9114 don't. Problem reported by Braden McDaniel in:

9126 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9128 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9129 best tool so far counter rely on the tool path variable name to
9130 avoid checks for one tool being affected by the results of running
9131 the length check on a previous tool.
9133 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9134 match expression argument, as different greps have different
9135 regular expression flavours.
9136 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9138 (AC_PROG_EGREP): Pass 'EGREP$'.
9139 (AC_PROG_GREP): Pass 'GREP$'.
9141 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9143 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9144 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

9148 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9149 Types, Specific Compiler Characteristics, System Services,
9150 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'

9166 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9167 now defines HAVE_DECL_TZNAME if it is declared, when
9168 HAVE_STRUCT_TM_TM_ZONE is not defined.
9169 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9170 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9181 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9182 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9183 H. F. Beebe for the bug report.

9239 * bin/Makefile.am (edit): Don't use $< in a context where
9240 POSIX doesn't require support for it. Use $@.in instead.
9241 Problem reported by Anthony N. Frasso in
9242 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9271 AC_SUBST provides no portable way to escape literal newlines.
9273 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9274 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9275 Darwin uses -lcrt2.o and there's little point to cataloging all
9276 the system variants. Partial fix reported by Andreas Waechter in:

9401 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9402 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9403 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9404 not <inttypes.h>. Problem reported by Tim Mooney in

9406 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9409 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9410 otherwise "make check" fails because it forbids cmp (I guess
9411 because cmp treats files as binary on DOS-like systems).

9414 have changed in 2004.
9416 2004-01-23 Gary V. Vaughan <gary@gnu.org>

9424 2004-01-15 Paul Eggert <eggert@twinsun.com>
9426 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9427 -std1 disables some useful extensions on Tru64. Problem reported

9433 * doc/autoconf.texi (Programming in M4sh): Document that
9434 AS_MKDIR_P succeeds if the destination is a symbolic link
9435 to an existing directory.
9436 (Limitations of Usual Tools): Note that mkdir -p might not
9437 succeed on symlinks to directories.

9973 The test suite are sometimes assigning timings incorrectly.
9974 Reported by Henk Krus.
9975 Diagnosed by Nicolas Joly.
9977 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9979 Instead of making AT_help a sequence of assignments to grow
9980 $at_help_all, just make AT_help_all be the growing contents of
9981 $at_help_all, and make a single assignment in...
9983 (at_times_skip): Flip the meaning and rename as...
9985 (AT_INIT): When summarizing the test that ran, remove
9986 $at_times_file after use, and check it is present before trying to

9993 * bin/Makefile.am (edit): Handle '@configure_input@'.
9994 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9995 (ifnames): chmod -w.
9996 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9997 executables, not bin/ executables! Otherwise all the magic needed
9998 to find non installed files is turned off. This caused a failure
9999 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10000 as found in its environment (sent by tests/autoreconf): pointing
10001 to bin/autom4te that could not find its files.
10002 * tests/mktests.sh: Force the replacement of generated files, for
10003 the sake of "mv" program that are interactive when overwriting a
10005 * config/install-sh: Upgrade from CVS Automake.
10007 2003-09-23 Paul Eggert <eggert@twinsun.com>

10010 versus test -L issues.
10012 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10013 Paul Eggert <eggert@twinsun.com>
10015 Trivial change to support GCC's configuration procedure.
10016 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

10018 about inconsistency if the preprocessor is set to give errors for

10048 2003-09-10 Akim Demaille <akim@epita.fr>
10050 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10051 willing to edit the output files.
10053 2003-09-10 Akim Demaille <akim@epita.fr>
10055 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10056 and AC_FC_FREEFORM.
10057 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10058 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10060 2003-09-09 Akim Demaille <akim@epita.fr>
10062 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

10078 2003-09-05 Paul Eggert <eggert@twinsun.com>
10080 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10081 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10083 2003-09-04 Akim Demaille <akim@epita.fr>

10096 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10098 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10100 Add support for newer Fortran dialects. The F77 interface is
10101 unchanged, and continues to support Fortran 77. New FC macros
10102 correspond to all the old F77 macros, with output variables FC,
10103 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10104 available dialect, but older dialects can be specified. There are
10105 new macros AC_FC_SRCEXT to set the source extension, and
10106 AC_FC_FREEFORM to accept free-form source files.
10108 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10110 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10111 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

10144 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10145 are defaulted by AT_CHECK anyway.
10146 Use AT_CHECK_AUTOM4TE.
10147 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

10203 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.

10206 * bin/autom4te.in: Adjust to output the call stack.
10207 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10209 2003-08-22 Akim Demaille <akim@epita.fr>

10222 Use &verb, not &verbose.
10224 2003-08-21 Akim Demaille <akim@epita.fr>
10226 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10228 ($help): Use Autom4te::ChannelDefs::usage.
10229 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10230 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10232 2003-08-21 Akim Demaille <akim@epita.fr>
10234 First stab at preserving warnings between calls to autom4te,
10235 including when the cache is used.
10237 There are still several issues: (i) there are too many runs of m4
10238 (one for include, one for warnings, and some more), (ii) warnings
10239 spreading on several lines are not handled gracefully, (iii) the
10240 code meant to have the call stack display for errors does not work
10241 (its handling should move from m4 to autom4te).
10243 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10245 (@preselect): Add m4_warn.
10246 ($exit_status): Remove, use $exit_code.
10247 ($help): Use Autom4te::ChannelDefs::usage.
10248 (&handle_m4): No longer define the m4_warnings.
10249 At each run, extract and report the warnings.
10250 Always cache the result, including if the exit status is on
10251 failure, since if nothing changes, we should result in the same
10252 failure, hence we can use the cache.
10253 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10254 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10256 (m4_warn): Redefine as a do-nothing: it is its invocation that
10257 matters, as warnings are now reported via traces.
10258 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10259 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10260 the latter reveals calls to the former.
10264 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10266 2003-08-21 Akim Demaille <akim@epita.fr>

10275 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10276 (&parse_warnings): Accept a list of warning requests.
10277 (&usage): Return a string, not a side effect.
10278 (cross): New warning category.

10282 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10283 (&require_configure_ac): Accept an optional directory argument.
10284 ($configure_ac): Remove.
10285 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10286 (&catfile): Remove.
10287 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10288 * bin/autoscan.in: Adjust.
10290 2003-08-20 Akim Demaille <akim@epita.fr>
10292 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10293 Reported by Alexandre Duret-Lutz.
10295 2003-08-20 Akim Demaille <akim@epita.fr>
10297 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10298 * bin/autom4te: Adjust.
10299 In particular, be Autoconf tools are really silent when properly
10300 working, bind the verbosity of the 'note' channel to $verbose.
10301 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10302 (&xsystem, &contents): Remove, since they are exported by...
10303 * lib/Autom4te/FileUtils.pm: this.
10305 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10306 * lib/Autom4te/FileUtils.pm: here.
10308 2003-08-20 Akim Demaille <akim@epita.fr>
10310 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

10364 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10365 shorter column three. Add DESCRIPTION to log file content.
10367 2003-08-13 Derek Price <derek@ximbiot.com>
10369 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

10402 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to

10423 2003-06-23 Akim Demaille <akim@epita.fr>
10425 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10426 not all of them. This fixes 1. the fact that when testing
10427 Autoconf there are many many config.log, 2. the incorrect use of
10428 top_srcdir to find config.log.
10429 Don't mix the detailed output of failed test with the summary of
10430 failures. Rather, append detailed log afterwards.
10432 2003-06-23 Akim Demaille <akim@epita.fr>
10434 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10525 2003-05-23 Akim Demaille <akim@epita.fr>
10527 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10528 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10529 the middle of a line).
10530 * lib/m4sugar/m4sugar.m4: Likewise.
10531 Remove useless spaces in comments.
10533 2003-05-23 Akim Demaille <akim@epita.fr>
10535 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

10547 Paul Eggert <eggert@twinsun.com>
10549 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10550 Remove `#include <stdlib.h>' from the list; we should never
10551 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10552 resulting namespace pollution would cause other tests to fail.
10553 Configure scripts run with some older versions of g++ and HP's
10554 aCC would fail due to such an #include. Problems reported by
10555 Matthew Mueller in <http://bugs.debian.org/120704> and by
10557 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10558 In the test, use the test declaration before including <stdlib.h>,
10559 as that's closer to how it'll be used.
10561 2003-05-23 Akim Demaille <akim@epita.fr>
10563 * doc/autoconf.texi (Header Portability): ucred.h.
10566 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10568 Overhaul Autotest's logging: generate separate log files
10569 in testsuite.dir/NNN/testsuite.log, and append them to
10570 testsuite.log instead of re-running the test verbosely.
10572 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10573 file descriptor, write 0 to at_status_file instead of setting
10574 at_status=0, initialize some new variables (at_status_file,
10575 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10576 to rerun the tests, instead append the at_group_log to the
10577 at_suite_log when a test fails.
10578 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10579 with the AS_MESSAGE_LOG_FD redirected to stdout.
10580 (AT_CLEANUP): save the output status in $at_status_file
10581 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10582 its original place.
10583 (AT_CHECK): since tests are run with a redirected stdout,
10584 and used to be re-run in verbose mode, turn some $at_verbose
10585 into echo, and don't redirect the output of testing stdout
10588 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10589 the name of the debugging directory and information about

10709 2003-05-06 Akim Demaille <akim@epita.fr>
10711 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10712 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10713 by aclocal.m4 is changed it might require the importing of another
10714 m4 extension file, i.e., aclocal must be run.
10716 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10717 (&parse_args): Use --force with aclocal if required and supported.

10731 2003-04-29 Derek Price <derek@ximbiot.com>
10733 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

10735 (AT_CLEANUP): Add `;' to end of at_help_all.
10736 (AT_INIT): Allow --keywords to be specified more than once. When
10737 grepping $at_help_all for keywords, use the field and keyword

10744 align better with others. I also made some of the individual

10938 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10939 format starting with "-".
10941 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10943 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10944 is not portable inside Makefile.
10946 2003-02-20 Akim Demaille <akim@epita.fr>
10948 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10949 compiler says yeah, but preproc says nope, compiler is right.
10950 Conversely, prompt the reader to send a bug report to the
10951 maintainers of the package, not of Autoconf.
10953 2003-02-20 Klee Dienes <kdienes@apple.com>
10955 * bin/autoreconf.in (autoreconf_current_directory): Properly
10956 handle an empty aclocal.m4.

10961 $ac_prefix_program.
10964 2002-12-23 Paul Eggert <eggert@twinsun.com>
10966 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10967 innocuous variant befor including <limits.h> or <assert.h>. This
10968 works around a bug reported by Albert Chin: HP-UX 11i
10969 (and earlier versions) have a <limits.h> that declares
10970 gettimeofday and many other functions.
10972 2002-12-03 Paul Eggert <eggert@twinsun.com>
10976 * NEWS, configure.ac: Update version.
10978 * doc/fdl.texi: Upgrade to FDL version 1.2.
10980 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10981 nontrivially in main's body, so that f's external declaration is
10982 not optimized away in AIX. This should fix the bug reported by
10984 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10986 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10987 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10988 defined, to support freestanding compilers. This should fix the
10989 bug reported by Momchil Velkov in
10990 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10992 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10993 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10994 obsolete AC_CHECK_TYPE. The missing empty arg was reported

10996 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
10998 * Makefile.maint (www-gnu): New macro.

11024 Update from masters.
11026 2002-11-14 Akim Demaille <akim@epita.fr>
11028 * Makefile.maint: Sync with Bison, i.e.:
11029 (po-check): Scan .l and .y files instead of the
11030 .c and the .h files that they generate. This fixes the bug
11031 reported by Tim Van Holder in:
11032 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11033 Look for N_ as well as for _. Try to avoid matching #define for
11037 2002-11-14 Akim Demaille <akim@epita.fr>
11039 * doc/autoconf.texi (C Compiler): Compiling several files at once.

11042 2002-11-14 Akim Demaille <akim@epita.fr>
11044 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11045 From Paul Eggert and Albert Chin-A-Young.

11049 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11050 than assigning in main, to avoid HP cc +O3 optimizing it away.
11052 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11054 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11055 option. Process --recheck after parsing all options. Pass -q
11056 option to configure on --recheck.
11057 (AC_OUTPUT): Pass -q from configure to config.status.
11058 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11059 arguments to record.
11060 * doc/autoconf.texi (config.status Invocation): Document
11061 config.status -q option.
11063 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11065 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11066 Makefile.in if Makefile.am exists.
11067 (output): Strip `.am' from Makefiles. Don't
11068 output AC_CONFIG_FILES if no Makefiles were found.

11088 Reported by Ezra Peisach.
11090 2002-11-05 Akim Demaille <akim@epita.fr>
11092 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11094 We _have_ to stop using the old compatibility scheme that tried to
11095 avoid useless backslashes because Libtool 1.4.3 contains a
11096 AC_DEFINE([error_t], [int],
11097 [Define to a type to use for \`error_t' if it is not
11098 otherwise available.])
11099 We _have_ to quote the single quote and backslashes with \. The
11100 old compatibility scheme saw that ` was backslashed, and therefore
11101 did not quote the single quote. Hence before this patch, Autoconf
11102 was not compatible with Libtool.
11104 2002-11-04 Paul Eggert <eggert@twinsun.com>
11106 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11147 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11148 Make variable, not a shell variable.
11149 Suggested by Bruno Haible.
11151 2002-10-31 Akim Demaille <akim@epita.fr>
11153 * bin/autom4te.in (load_configuration): Reject #args out of any
11156 2002-10-31 Akim Demaille <akim@epita.fr>

11176 Problem reported by Bruno Haible.

11180 * doc/autoconf.texi (Header Templates): Put also in words what the

11182 (Customizing autom4te): s/--cache=/--cache /.
11184 2002-10-29 Akim Demaille <akim@epita.fr>

11445 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11446 characters is a syntax warning now.
11447 (_AS_QUOTE): Accept $2 as list of characters to quote.
11448 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11449 Quote for Perl, not sh.
11450 * bin/autoheader.in: When $debug, report the file which is
11452 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11453 `@', to tickle Perl's lists.
11454 Reported by Carlos Velasco.
11456 2002-10-18 Akim Demaille <akim@epita.fr>
11458 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11459 missing included files _are_ errors.
11460 Thanks to Alexandre Duret-Lutz.
11461 * tests/tools.at (autom4te cache): Adjust.
11462 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

11468 2002-10-17 Akim Demaille <akim@epita.fr>
11470 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11471 Fixes the `AC_ARG_VAR' test failures.
11472 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11473 * lib/freeze.mk (check-forbidden-patterns): New.

11487 (ansi2knr.c-url_prefix): Remove.
11489 2002-10-16 Akim Demaille <akim@epita.fr>
11491 Because of caching, some files that no longer exist and are no
11492 longer required can still cause errors.
11493 Reported by Alexandre Duret-Lutz.
11495 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11496 to frozen files in @ARGV, as @ARGV must remain being a list of
11497 files. Rather, at M4 call sites, use this...
11498 (&files_to_options): New function.
11499 (&freeze): Use &error.
11500 (&up_to_date): If a file that was included according to the cache
11501 is no longer there, then the output is out dated.
11502 (&main): Don't even check whether a file is up to date is anyway
11504 * tests/tools.at (autom4te cache): New.
11506 2002-10-16 Akim Demaille <akim@epita.fr>
11508 * bin/autoconf.as: Kill dead options.
11509 * bin/autoupdate.in (&parse_args): Kill old options.
11510 * bin/autoreconf.in (&parse_args): Remove dead options.
11512 (&autoreconf): Report the directories we enter *and leave*, so
11513 that error messages can be easily located, and use GNU Make
11514 format, so that Emacs' compile mode understands us.
11515 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11516 if some file was changed instead of `print'.
11517 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11518 (&parse_args): Remove the dead options.
11519 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11520 autoheader's quiet mode.

11525 2002-10-11 Akim Demaille <akim@epita.fr>
11527 No longer use CPP to check for the existing of headers: use CC to
11528 check for compilability.

11548 2002-10-11 Akim Demaille <akim@epita.fr>
11550 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11551 file name to enable parallel executions.
11552 From Sam Varshavchik.
11554 2002-10-08 Akim Demaille <akim@epita.fr>
11556 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11557 aclocal invocation, as Gettext macros might not be visible to
11559 Instead of blindly running autopoint, scan configure.ac (not the
11560 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11561 Reported by Paul D. Smith.
11563 2002-10-08 Paul Eggert <eggert@twinsun.com>
11565 Work around problems found when POSIXLY_CORRECT=1 is set.
11566 None of this seems to have anything to do with POSIX, really,
11567 but it's how Perl getopt works.
11568 * bin/autom4te.in (parse_args): Configure GetOpt with
11570 * doc/autoconf.texi (Invoking autom4te):
11571 --warning -> --warnings.

11591 2002-09-28 Akim Demaille <akim@epita.fr>
11593 * tests/torture.at (Configuring subdirectories): Be robust to
11594 users who use config.site to require for a cache: in this case,
11595 the two last configure runs, using two different sets of
11596 arguments, trigger a legitimate error.
11598 2002-09-28 Akim Demaille <akim@epita.fr>

11614 (tm_zone): Move their rules to...

11616 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11617 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11618 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

11631 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11632 (.m4.m4f): Don't pass --prepend-include, since that's done by
11633 tests/autom4te itself.
11634 * lib/autoscan/Makefile.am: Include freeze.mk.
11635 (autoscan.list): New target --this file is no longer a source.
11636 (autoscan.pre): New file.
11638 2002-09-28 Akim Demaille <akim@epita.fr>
11640 * bin/autoscan.in (@kinds): Make them singular.
11642 (&init_tables): When --debug, report the list of rules to ease
11643 tracking changes in autoscan.list.
11644 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11646 2002-09-28 Akim Demaille <akim@epita.fr>

11657 * lib/autoscan/identifiers, lib/autoscan/makevars,
11658 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11659 `functions' line is now prefixed with `function:'.
11660 * bin/autoscan.in (&init_tables): Adjust.
11662 2002-09-28 Akim Demaille <akim@epita.fr>
11664 From now on, autoscan files must always map a macro name to a
11665 word: there is no `default' macro for autoscan.
11667 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11669 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11672 2002-09-28 Akim Demaille <akim@epita.fr>
11674 * bin/autoscan.in (%c_keywords): Remove.
11675 (&used): Keep only track of the words we might be interested in.

11708 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11710 2002-09-26 Akim Demaille <akim@epita.fr>
11712 Single suffix rules and seperated dependencies are not portable.

11716 Separated Dependencies'.
11717 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)

11720 2002-09-25 Paul Eggert <eggert@twinsun.com>
11722 * BUGS (Interoperability bugs): New section. Mention libtool
11723 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11725 2002-09-24 Paul Eggert <eggert@twinsun.com>
11727 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11728 make handles suffix-rules differently from GNU make.
11730 * bin/Makefile.am (SUFFIXES, .in): Remove.
11731 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11732 Move the body of the old .in rule here.
11734 2002-09-16 Akim Demaille <akim@epita.fr>
11736 i960 compilers create `b.out' files by default.

11745 reference to `struct timezone' in the description of

11756 2002-09-13 Akim Demaille <akim@epita.fr>
11758 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11759 reading config.log when the compiler is rejected.
11760 Suggested by Guido Draheim.
11762 2002-09-13 Akim Demaille <akim@epita.fr>
11764 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11765 (chdir_init) might hang when stat'ing mounted directories.
11766 Reported by Vance Shipley.
11768 2002-09-12 Akim Demaille <akim@epita.fr>
11770 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not

11775 * doc/autoconf.texi (Defining Symbols): Present two different
11776 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

11781 * doc/autoconf.texi: Review grammar and punctuation.

11785 * doc/autoconf.texi: Fix minor formatting, spelling, and
11787 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11788 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11791 2002-09-11 Akim Demaille <akim@epita.fr>
11793 * doc/autoconf.texi (Questions): Rename as...
11795 (Defining Directories): New.
11797 2002-09-09 Akim Demaille <akim@epita.fr>
11799 * doc/autoconf.texi (Making testsuite Scripts): Update.
11800 Suggested by Nishio Futoshi.
11802 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11804 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11805 plain `@' is wanted.
11807 2002-09-09 Akim Demaille <akim@epita.fr>
11809 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11810 `duplicates', since the algorithm was too naive and could keep
11811 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11812 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11813 Reported by Ralf Corsepius.

11822 directory is relative.
11823 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11824 directory definition.

11830 precious variables are.
11831 Suggested by Pontus Skoeld.
11833 2002-09-05 Akim Demaille <akim@epita.fr>
11835 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11836 (ifnames, autoscan, autom4te): Since we don't only depend on
11837 configure.ac variables (such as VERSION etc.), but also on prefix
11838 and so forth, depend on Makefile, not configure.ac.
11839 Reported by Alexandre Duret-Lutz.
11840 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11842 2002-09-05 Kevin Ryde <user42@zip.com.au>
11844 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

11849 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by

11860 2002-09-03 Akim Demaille <akim@epita.fr>
11862 * configure.ac: Bump to 2.53d.
11863 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11864 as of today, on Automake's team suggestion.
11866 2002-09-03 Akim Demaille <akim@epita.fr>
11870 2002-09-02 Akim Demaille <akim@epita.fr>
11872 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11874 * configure.ac: Disable SITE_MACRO_DIR.
11876 2002-09-02 Jim Meyering <meyering@lucent.com>
11878 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11879 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11880 Also, tweak grammar: s/make sure to/be sure to/.
11882 2002-09-02 Paul Eggert <eggert@twinsun.com>
11884 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11885 directory names are generally preferable to physical names.
11887 2002-09-02 Akim Demaille <akim@epita.fr>
11889 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11890 Reported by Raja R. Harinath.
11891 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11892 * bin/autoupdate.in: Use error instead of die.
11894 2002-09-01 Paul Eggert <eggert@twinsun.com>
11896 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11897 ordinary shell concatenation rather than echo+tr+sed command that
11898 runs afoul of a long-line-related sed bug in Solaris 8.
11900 * bin/autoheader.in (parse_args): --warning -> --warnings.
11902 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11903 stdout, as traditional "ls" does.
11904 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11905 _AC_COMPILER_EXEEXT_O): Likewise.
11906 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11908 * bin/autoconf.as: Add --prepend-include option. This patch was
11909 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11910 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11912 * bin/autoconf.in, configure: Regenerate.
11914 * doc/autoconf.texi (Special Shell Variables): Mention
11915 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11917 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11918 MAILPATH and set PS1, PS2, PS4 to default values, to work
11919 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11920 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11921 the Autoconf documentation specifies; fall back to "unset" only if
11922 this fails. Use a shell for-loop for this rather than an m4 loop,
11923 to shorten the output script.
11925 2002-08-30 Paul Eggert <eggert@twinsun.com>
11927 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11928 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11929 for the CDPATH problem. Document PWD.
11930 (Limitations of Builtins): Document the problem that "cd $foo" and
11931 "ls $foo" may refer to different directories in shells conforming
11932 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11933 example, since the old example is now out of date.
11935 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11936 FOO" and "ls FOO" talk about different directories; this catches
11937 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11940 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11941 of rolling our own unset.
11942 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11943 in practice we needn't worry about CDPATH if unset doesn't work.
11945 * Makefile.in, aclocal.m4, bin/Makefile.in,
11946 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11947 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

11967 2002-08-29 Akim Demaille <akim@epita.fr>
11969 * lib/Autom4te/General.pm (&xqx): New.
11970 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11971 hand, which is not portable.
11973 * bin/autom4te.in: Use them.
11974 Use &error instead of die.
11975 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11978 2002-08-17 Paul Eggert <eggert@twinsun.com>
11980 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11981 default list of compilers to try, since it was long ago superseded
11982 by the ksh fc builtin. Suggested by Steven G. Johnson.
11984 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11986 * doc/autoconf.texi (Invoking autom4te): End the option table,
11987 fixing a bug introduced by the previous patch.
11988 (Limitations of Make): Add a 'target lookup' subentry in the
11989 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11991 2002-07-29 Mark D. Roth <roth@feep.net>
11993 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11994 options and use $AUTOM4TE_PATH.
11995 * doc/autoconf.texi: Remove documentation of autom4te
11996 --include-envvar and --site-macro-subdir options and document
11997 use of $AUTOM4TE_PATH.

11999 arguments from each language section.

12003 * doc/install.texi: Include copyright symbol in copyright notice.
12005 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12007 (AM_MAKEINFOFLAGS): New macro.
12008 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12009 * Makefile.am (INSTALL): Use the new macros.
12010 Use -o rather than --output, since "missing" does not grok --output.
12012 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12014 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12015 comments do not always work. Never trust the exit status of

12020 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):

12023 2002-07-23 Paul Eggert <eggert@twinsun.com>
12025 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12026 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12027 apparently treats PATH="nonexistent" as if it contained ".".
12028 Bug reported by Stefan `Sec' Zehl.

12154 2002-06-27 Paul Eggert <eggert@twinsun.com>
12156 * config/install-sh: Quote $src. Prefer || to test's -o option,
12157 as per "Limitations of Builtins".
12158 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12159 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

12185 2002-06-11 Andreas Schwab <schwab@suse.de>
12187 * doc/autoconf.texi: Add more dir entries.
12189 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12191 * bin/autom4te.in ($cache): Don't define using `$me', the name
12192 of the cache should not depend on the name under which autom4te

12223 Suggested by Adam J. Richter.
12225 2002-06-07 Akim Demaille <akim@epita.fr>
12227 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

12230 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12231 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.

12286 2002-05-22 Paul Eggert <eggert@twinsun.com>
12288 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12289 from the default list of compilers to try. Suggested by
12291 * NEWS: Document the above.
12292 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.

12296 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12297 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12298 This improves on an earlier suggestion by H. Peter Anvin.
12300 2002-05-16 Paul Eggert <eggert@twinsun.com>
12302 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12303 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12304 Both macros now accept an optional source-dir arg.
12305 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12307 * NEWS: Document this.
12308 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12310 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12311 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12312 not for GNU extensions; this undoes part of the 2000-11-03 change,
12313 reverting to 2.13-compatible behavior.
12314 Add new optional argument DIR.
12315 (AC_FUNC_FNMATCH_GNU): New macro.
12317 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12319 2002-05-08 Paul Eggert <eggert@twinsun.com>
12321 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12322 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12323 and it causes a 'test' syntax error if it fails.
12324 Bug reported by Stephen Gildea.
12326 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12327 If prototypes are supported, use them to check this at compile-time,
12328 instead of trying to check it at run-time. If we must do a run-time
12329 check, assume that setvbuf is standard when cross-compiling, as
12330 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12331 Bug reported by Paul D. Smith.
12333 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12334 argument specifying location of getloadavg.c. This removes a
12335 FIXME. This idea was taken from Jim Meyering's implementation in
12337 * doc/autoconf.texi (Particular Functions): Document this.
12338 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12339 that's what the code does; this fixes a bug reported by
12342 2002-05-03 Akim Demaille <akim@epita.fr>
12344 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12345 autopoint instead of gettextize.
12346 ($uses_alocal): Rename as...
12347 ($uses_aclocal): this.
12348 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12349 Suggested by Bruno Haible.
12351 2002-05-03 Akim Demaille <akim@epita.fr>
12353 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12355 2002-04-29 Paul Eggert <eggert@twinsun.com>
12357 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12358 files to be 1 second older; just set them to be the same time.
12359 Also, sleep 1 second after the first aclocal, to work around
12360 problems with sub-second time stamps on the input files.
12362 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12364 * doc/autoconf.texi: Mention "set -e -x" lossage
12365 under node "Limitations of Builtins".
12367 2002-04-29 Akim Demaille <akim@epita.fr>
12369 * doc/install.texi: Better wording for setting variables when
12371 From Christian Cornelssen.
12373 2002-04-29 Akim Demaille <akim@epita.fr>
12375 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12376 of lack of $LINENO support, then the test will compare the $LINENO
12377 in testsuite vs. the lineno in the test file. This is wrong, of
12379 Be sure to protect it.
12380 Reported by Patrick Welche.
12382 2002-04-25 Akim Demaille <akim@epita.fr>
12384 * doc/autoconf.texi (Obsolete Macros): Typo.
12385 Reported by Vladimir Volovich.
12387 2002-04-25 Akim Demaille <akim@epita.fr>
12389 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12390 than some of the input files, hence, on the second run of aclocal,
12391 if some of its input are younger, make them older.
12392 Suggested by Paul Eggert.
12394 2002-04-25 Akim Demaille <akim@epita.fr>
12396 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12401 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12402 and ac_subst_vars be sh variables containing the list of
12403 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the

12470 Minor spelling and grammar fixes.
12472 * doc/autoconf.texi: Follow the outline suggested in the GNU
12473 Sample Texts sections of the Texinfo 4.2 manual. Most
12474 importantly, this makes sure that the copyright notices appear in
12475 all output formats. You probably need Texinfo 4.2 to generate

12504 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

12514 workaround for ${1+"$@"}.
12515 * doc/autoconf.texi (Shell Substitutions): Explain it.
12516 From Oliver Kiddle and Peter Stephenson.
12518 Have M4sh perform minimal shell sanitizing.
12520 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12522 (_AS_PREPARE): this new macro.
12524 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12525 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12527 Adjust Autoconf and Autotest.
12529 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12530 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12531 * lib/autotest/general.m4 (AT_INIT): Likewise.
12532 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12533 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12536 Use this M4sh to generate Autoconf's shell scripts.
12538 * tests/wrapsh.as: New, precursor of wrapsh.in.
12539 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12540 on Autotest and M4sh.
12541 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12542 (wrapsh.in): New target.
12543 * bin/autoconf.as: New, precursor of autoconf.in.
12544 (autoconf.in): New target.

12567 2002-04-04 Andreas Schwab <schwab@suse.de>

12574 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

12576 Use dnl, not the KILL diversion.
12578 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12579 (AC_CONFIG_LINKS): here.
12581 Don't use the KILL diversion, as it kills spurious output, which
12582 results in failures being hidden.
12583 Use m4_defn where appropriate.
12584 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12585 after the second argument.
12587 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12588 syntax, as it is provided by M4sugar.

12630 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12631 to avoid versions of HP C which don't allow that.
12633 2002-03-27 Paul Eggert <eggert@twinsun.com>
12635 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12636 (AS_SHELL_SANITIZE): Invoke it.

12647 2002-03-25 Paul Eggert <eggert@twinsun.com>
12649 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12650 as POSIX requires, as it doesn't work with Zsh.
12651 * doc/autoconf.texi (Assignments): Document the problem.
12653 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12655 * doc/autoconf.texi (Limitations of Make): Mention more issue
12656 about VPATH, overriding of macros in sub-makes, and handling of
12659 2002-03-21 Paul Eggert <eggert@twinsun.com>
12661 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12662 problem with here-document buffer boundaries.
12664 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12665 when reinvoking the shell, to work around problems with installers
12666 who put strange things like "cd" commands in their environments.

12686 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12690 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12691 (Limitations of Usual Tools): Add mkdir section.
12693 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12694 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12695 back on AS_DIRNAME to compute prefixes otherwise; this is
12696 roughly what mkinstalldirs does. That way, we need not have
12697 our own filename disassembler. The old disassembler did not
12698 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12700 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12701 Create at_test_all by a series of assignments,
12702 not by a single assignment of a long string. The latter causes ksh
12703 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12704 presumably because of a buffer overrun.
12706 2002-03-14 Paul Eggert <eggert@twinsun.com>
12708 * lib/autotest/general.m4 (at_times_skip):
12709 Renamed from at_times. Now a boolean.
12710 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12711 says 'times: not found'.

12743 does not do it if --with-lispdir is given.

12752 subdirectory should exist.
12754 2002-03-08 Akim Demaille <akim@epita.fr>
12756 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12758 2002-03-08 Akim Demaille <akim@epita.fr>
12760 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12761 aliases the actual variables, and modifications of the former
12764 2002-03-08 Akim Demaille <akim@epita.fr>
12766 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12767 because of C-c: have m4 output in tmp files, then mv them.

12801 * doc/autoconf.texi (Transforming Names): Equality between target
12802 and host is irrelevant.
12803 (Specifying Names, Canonicalizing): Remove all references to the
12804 backward compatibility hooks. Rather, collect them all into...
12805 (Hosts and Cross-Compilation): this new section.
12806 * doc/install.texi (System Type): Ditto.
12807 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12808 that `--host' implies cross-compilation.

12812 * doc/autoconf.texi (Evaluation Macros): New.
12813 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally

12816 that it contains exactly the items, not an expression which
12817 evaluation is the current item.
12818 (m4_re_string, m4_re_word): Don't over quote them.
12820 2002-03-04 Akim Demaille <akim@epita.fr>
12822 Instead of having stacking `shift's evaluated at the end, let
12823 `foreach' loops immediately evaluate them.
12825 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12826 $*. This is the n-th time I change my mind, but hopefully this is
12829 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12831 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12832 it was only a hack for m4_text_wrap.
12833 (m4_car2): Remove, replaced by...
12835 (_m4_foreach): Adjust.
12836 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12837 m4_bpatsubst for clarification.

12920 * doc/autoconf.texi (Specific Compiler Characteristics):
12921 Describe HP-UX cc bug workaround more accurately.
12922 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12924 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12925 cross-compilers, too. This undoes some of the most recent change
12928 2002-02-05 Akim Demaille <akim@epita.fr>
12930 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12931 to make sure they are up to date when `check' is run.
12933 2002-02-05 Akim Demaille <akim@epita.fr>
12935 * doc/autoconf.texi (Making testsuite Scripts): Document
12938 2002-02-05 Akim Demaille <akim@epita.fr>
12940 * lib/freeze.mk: New.
12942 2002-02-05 Akim Demaille <akim@epita.fr>
12944 Implement `autom4te --freeze'.
12946 * bin/autom4te.in (&freeze): New.
12947 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12948 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12950 2002-02-05 Akim Demaille <akim@epita.fr>
12952 * bin/autom4te.in (&parse_args): Implement `frozen files are
12953 optional are the sum of the previous files on the command line'.
12954 Also, pass `--reload-state=' on them, so...
12955 (handle_m4): don't.
12956 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12957 (M4sh): Rely on M4sugar.
12958 (Autotest, M4sh, M4sugar): Use frozen files.
12960 2002-01-31 Akim Demaille <akim@epita.fr>
12962 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12963 * doc/autoconf.texi (Initializing configure): Adjust.
12965 2002-01-30 Akim Demaille <akim@epita.fr>
12967 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12968 alphanumeric to `-' instead of `_'.
12970 2002-01-30 Akim Demaille <akim@epita.fr>
12972 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12973 for plain code, the other for cross-compilation code. The latter
12974 is now run with GCC only.
12975 * doc/autoconf.texi (Compilers and Preprocessors): New.
12977 2002-01-30 Akim Demaille <akim@epita.fr>
12979 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

12982 change AC_INIT default values.
12984 2002-01-29 Akim Demaille <akim@epita.fr>
12986 * tests/torture.at (Configuring subdirectories): Use configure.in,
12987 so that aclocal 1.4 works.
12988 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12990 2002-01-28 Akim Demaille <akim@epita.fr>
12992 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12995 2002-01-28 Akim Demaille <akim@epita.fr>
12997 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12998 AUTOTEST_PATH *after* it was set.
12999 Don't put `.' in the PATH: the user should be precise and `./' if
13000 needed. In addition, given that the test suite does some `cd', if
13001 `.' is in the path, the `tested programs' sections will report
13002 programs found in the test suite's directory, while during the
13003 tests (performed in their own directory), these programs are no
13004 longer visible. In other words, the results is confusing and
13006 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13015 * doc/autoconf.texi: Finally add Akim as an author.
13017 2002-01-24 Akim Demaille <akim@epita.fr>
13019 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13020 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13021 Bourne. Use /bin/sh.
13022 From Andreas Buening.
13024 2002-01-24 Akim Demaille <akim@epita.fr>
13026 * config/config.guess, config/config.sub, config/texinfo.tex:
13027 Update from masters.
13029 2002-01-24 Akim Demaille <akim@epita.fr>

13040 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13041 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13042 Reported by Geir Ove Myhr.
13044 2002-01-21 Akim Demaille <akim@epita.fr>
13046 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13048 2002-01-21 Akim Demaille <akim@epita.fr>
13050 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13051 message on invalid options.
13052 * bin/autom4te.in (parse_args): Don't use
13053 Autoconf::General::getopt with non valid options.
13055 2002-01-17 Jim Meyering <meyering@lucent.com>
13057 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13058 $ac_cv_exeext so we don't use an old, invalid, cached value.
13060 2002-01-11 Akim Demaille <akim@epita.fr>
13062 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

13072 package.m4, since is really depends upon configure.ac, not
13074 * doc/autoconf.texi (testsuite Scripts): Adjust.
13075 * tests/Makefile.am (package.m4): New.
13076 EXTRA_DIST it since its a source.
13078 2002-01-06 Akim Demaille <akim@epita.fr>
13080 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13081 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13082 and PACKAGE_BUGREPORT from here...
13083 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13085 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13086 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13087 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13088 * tests/tools.at (autoheader): Adjust.
13089 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13091 2002-01-06 Akim Demaille <akim@epita.fr>

13108 * doc/autoconf.texi (New Macros): Tweak wording.
13110 2001-12-14 Akim Demaille <akim@epita.fr>
13112 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13113 trailing files, don't apply `-rf' to files which might not be
13114 created by configure (core, core.*, and *.core), but just `rm -f'.
13115 Suggested by Jonathan Kamens.
13117 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13119 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13121 2001-12-14 Akim Demaille <akim@epita.fr>
13123 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13125 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13127 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13128 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13129 abs_srcdir, top_srcpath to abs_top_srcdir.
13130 (_AC_OUTPUT_FILES): Adjust.
13131 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13132 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,

13141 2001-12-12 Kevin Ryde <user42@zip.com.au>
13143 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13144 forbidden file descriptors table.
13146 2001-11-26 Akim Demaille <akim@epita.fr>
13148 * bin/autoscan.in (%c_keywords): Build it at top level.
13149 Map to 1 in order to simplify its uses.
13151 2001-11-26 Akim Demaille <akim@epita.fr>
13153 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13154 Remove $filepath, useless.
13155 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13156 variables, they are really part of the tokens.
13157 Split the input line on spaces and then look for tokens.
13158 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13159 because of `lex$U.$(OBJEXT)'.
13160 (&scan_files): Use "@list" instead of join.
13161 * doc/Makefile.am (CLEANFILES): Add *.fns.
13163 2001-11-26 Akim Demaille <akim@epita.fr>

13166 Remove, replaced by...
13167 * tests/wrappl.in: Be common for all the Perl executables.
13168 In particular autoscan and autoheader want -I.
13169 * configure.ac: Adjust.
13170 * lib/autoscan/headers: errno.h is portable.
13172 2001-11-26 Akim Demaille <akim@epita.fr>
13174 * bin/autoscan.in (used): New.
13177 2001-11-26 Akim Demaille <akim@epita.fr>
13179 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13181 (&scan_sh_file): Remove a duplicate pattern.
13182 (&check_configure_ac): Use long options.
13183 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

13188 Before, having a line containing the opening of a multi line
13189 comment made the whole line be ignored.
13191 2001-11-26 Akim Demaille <akim@epita.fr>
13193 * doc/autoconf.texi (Using an Autotest Test Suite): New.

13199 Test groups are now run two directories deeper.
13201 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13202 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13204 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13205 top_srcdir, builddir and top_builddir.
13206 Use `at_*dir' relatively to the directory containing the
13207 suite, use `*dir' when relatively to the current group dir.
13209 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13211 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13212 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13213 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13216 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13218 * doc/autoconf.texi (Using System Type): Add an example of `case
13219 $host' usage so people quit using `case $target' everywhere.
13221 2001-11-22 Akim Demaille <akim@epita.fr>
13223 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13224 spotted by Jim Meyering.
13226 2001-11-16 Paul Eggert <eggert@twinsun.com>
13228 This patch implements a `long double' suggestion by Oliver Kiddle.
13230 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13231 static, to catch errors if the value isn't known at compile-time
13232 and the compiler supports dynamic arrays. Change its name from
13233 `_array_' to `test_array' to avoid potential name clashes.
13234 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13235 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13236 better than double. Catch a bug in GCC 2.95.2 x86.
13237 * doc/autoconf.texi (C Compiler): Document the above.
13240 2001-11-13 Akim Demaille <akim@epita.fr>
13242 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13244 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13246 2001-11-13 Akim Demaille <akim@epita.fr>
13248 * lib/autotest/general.m4 (AT_INIT): After having run the test
13249 group, go back to the initial directory, not to at_suite_dir.
13251 2001-11-13 Akim Demaille <akim@epita.fr>
13253 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13254 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13255 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13257 (AT_CHECK_CONFIGURE): Use absolute paths.
13258 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13259 The problem is still the old one: there is no means in M4 (that I
13260 know about) to create a defining macro, because there is no means
13261 to create `$1' etc., therefore, the defining macro ``swallows''
13262 all the arguments meant to the defined macro.
13264 2001-11-13 Akim Demaille <akim@epita.fr>
13266 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13267 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13269 * tests/aclocal.m4: Remove, as it is no longer used.
13271 2001-11-13 Akim Demaille <akim@epita.fr>
13273 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13274 variable names when referring to a single test group, or to
13275 `suite' when referring to the whole test suite.
13276 `at_last_test' is removed: m4 compute at_format itself.
13277 (at_stdout, at_stder1, at_stderr): New variables.
13278 (AT_CHECK): Use them.
13280 2001-11-13 Akim Demaille <akim@epita.fr>
13282 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13284 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13285 Do it as soon as a test fails, don't wait till the end of the test
13287 Don't remove $as_me.[0-9]*, since these files no longer exist.
13289 2001-11-13 Akim Demaille <akim@epita.fr>
13291 * tests/tools.at: Use absolute paths, since we are no longer run
13294 2001-11-13 Akim Demaille <akim@epita.fr>
13296 Now that tests are running in their own private dir, there is no
13297 need to list the files to remove at the end of tests groups.
13299 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13300 (AT_data_files, at_data_files): Remove.
13301 (AT_CLEANUP, AT_DATA): Simplify.
13303 Remove the group dir if !debug && !failed.
13304 * tests/atspecific.m4: Adjust.
13306 2001-11-13 Akim Demaille <akim@epita.fr>
13308 Start a new layout for Autotest: `testsuite' creates
13309 `testsuite.dir' in which the at-check-line etc. files are to be
13310 found, and `testsuite.dir/003' where the test group 3 is run.
13312 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13313 at_check_line_file, at_format, at_test_normalized, at_group_dir
13315 Create the directories.
13316 Use absolute paths for at- files.
13317 (AT_CHECK): Adjust.
13319 2001-11-11 Michael Matz <matz@kde.org>
13321 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13323 (m4_car): Properly quote arguments.
13325 2001-11-13 Akim Demaille <akim@epita.fr>
13327 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13328 with stricter rules on LIBOBJS.
13330 2001-11-12 Paul Eggert <eggert@twinsun.com>
13332 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13333 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13336 2001-11-12 Akim Demaille <akim@epita.fr>
13338 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13340 2001-11-12 Akim Demaille <akim@epita.fr>
13342 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13343 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13344 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13345 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13346 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13347 specify to what the macro should be defined (typically to 1).
13349 2001-11-12 Akim Demaille <akim@epita.fr>
13351 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13354 2001-11-12 Akim Demaille <akim@epita.fr>
13356 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13357 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13358 definition used by Automake where LEX is +/- "${missing} lex" and
13359 `missing' itself contains variables.
13361 2001-11-12 Akim Demaille <akim@epita.fr>
13363 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13364 Now that M4sh pushes BODY, the comments were output at the end of
13367 2001-11-08 Akim Demaille <akim@epita.fr>
13369 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13370 that we can trace macros from aclocal.m4.
13371 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13372 obsoleted, and redirect to the former anyway.
13373 Reported by Ralf Corsepius.
13375 2001-11-08 Akim Demaille <akim@epita.fr>
13377 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13378 processed only if present.
13379 * tests/torture.at (Configuring subdirectories): Use autoreconf
13380 instead of successive calls to autoconf.
13381 Add a nonexistent subdirectory to exercise the patch above.
13382 Reported by Ralf Corsepius.
13384 2001-11-08 Kevin Ryde <user42@zip.com.au>
13386 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13387 doesn't accept .S files.
13389 2001-11-07 Akim Demaille <akim@epita.fr>
13391 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13392 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13393 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13394 * bin/autom4te.in (warn_forbidden): New.
13395 (handle_output): Use it.
13396 Read m4_pattern_forbid with messages.
13398 2001-11-05 Akim Demaille <akim@epita.fr>
13400 * bin/autom4te.in (--normalize): Remove.
13401 * lib/autom4te.in: Adjust.
13403 2001-11-05 Akim Demaille <akim@epita.fr>
13405 * tests/Makefile.am (testsuite): Rename this target as...
13406 ($(TESTSUITE)): this.
13409 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>

13437 2001-11-03 Akim Demaille <akim@epita.fr>
13439 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13440 (@export_forward_subs): New.
13441 Add basename, dirname, and fileparse.
13443 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13444 Don't look for aclocal flags if we already know aclocal is not
13446 Move aclocal.m4t only if it exists.
13447 Reported by Ezra Peisach.
13449 2001-11-03 Akim Demaille <akim@epita.fr>
13451 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13452 passed on command line, defaulting to ./configure.ac if present.
13453 (&maybe_autoreconf, File::Find): Remove, unused.
13454 (&autoreconf): If autoconf is not used, don't try to trace.
13456 2001-11-02 Akim Demaille <akim@epita.fr>
13458 * configure.ac: Bump to 2.52g.
13460 2001-11-02 Akim Demaille <akim@epita.fr>
13464 2001-11-02 Akim Demaille <akim@epita.fr>
13466 * config/config.guess, config/config.sub, doc/standards.texi:
13467 * config/lispdir.m4: Update from masters.
13468 * configure.ac: Bump to 2.52f.
13470 2001-11-02 Akim Demaille <akim@epita.fr>
13472 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13473 Don't run aclocal when aclocal.m4 is not from aclocal.
13475 Don't run libtoolize and gettextize if --install is not given.
13477 2001-11-01 Paul Eggert <eggert@twinsun.com>
13479 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13480 be invoked before _AS_LINENO_PREPARE.
13481 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13482 than character ranges.
13484 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13485 invoking AS_BASENAME. Set the locale variables to 'C' if
13486 possible, as POSIX requires this to get the traditional
13488 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13490 2001-10-31 Paul Eggert <eggert@twinsun.com>
13492 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13493 with {}, as that triggers a bug in Bash 2.05.
13495 (_AS_LINENO_PREPARE): Use Sed rather than
13496 Awk. Fix the sed prepass to work even if there are multiple
13497 instances of $LINENO on the same line. Do not substitute for
13498 other variables like $LINENOT. Do not check file dates; such a
13499 check is unreliable on sufficiently fast machines, and removing
13500 the check makes the code simpler and more reliable. Check for
13501 output and chmod failures.
13503 * doc/autoconf.texi (Special Shell Variables): Document
13506 2001-10-31 Akim Demaille <akim@epita.fr>

13513 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13514 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13515 provided, while it is optional.
13516 * configure.ac: Adjust.
13518 2001-10-26 Paul Eggert <eggert@twinsun.com>
13520 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13521 lib/Autom4te/Struct.pm:
13522 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13525 * doc/autoconf.texi (Special Shell Variables): Document some
13526 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13528 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13529 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13530 eval $LINENO is not portable in practice.
13532 2001-10-24 Akim Demaille <akim@epita.fr>
13534 * lib/Autom4te/General.pm (backname): New.
13536 2001-10-24 Akim Demaille <akim@epita.fr>

13544 2.05's use of ANSI quoting in its `set' builtin.
13546 2001-10-22 Paul Eggert <eggert@twinsun.com>
13548 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13549 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13550 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13551 POSIX decided to standardize on the int flavor of strerror_r.
13552 Always do char* test, as there's no reason not to.
13553 Assign to a char* var, to catch strerror_r that returns int*.
13555 * doc/autoconf.texi (Particular Functions):
13556 Document the above changes. Also, document the fact that
13557 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13559 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13561 2001-10-20 Akim Demaille <akim@epita.fr>
13563 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

13566 2001-10-20 Akim Demaille <akim@epita.fr>
13568 * lib/Autom4te/General.pm (&update_file): If destination is
13569 unchanged, remove the source.
13570 (&up_to_date_p): Don't be verbose, be debug.
13571 * bin/autoreconf.in: No longer support --m4dir.
13572 (&autoreconf): Display the full path of the configure.ac we are
13574 Trace it only once.
13575 Be sure to honor --force with gettextize.
13576 Always run aclocal.
13577 * doc/autoconf.texi: Adjust.
13579 2001-10-20 Akim Demaille <akim@epita.fr>
13581 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13583 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13584 `intl' is already present, as it refuses unless --force.
13585 (&parse_args): Use -I, --include instead of the old Autoconf
13587 ($localdir, $autoconf_dir): Remove.
13589 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13591 2001-10-19 Jens Petersen <petersen@redhat.com>
13593 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13606 comment, explain how to install automatic mode selection.
13609 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13611 * bin/autoreconf.in (autoreconf): Display the path to the
13612 configure.ac being studied.
13614 2001-10-18 Paul Eggert <eggert@twinsun.com>
13616 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13617 long, to work around a bug in the HP C compiler version HP92453-01
13620 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13621 (AS_BASENAME_EXPR): New macro.
13622 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13623 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13624 and fall back on 'sed' only if the other two fail. This makes
13625 AS_BASENAME act more like AS_DIRNAME.
13626 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13627 contains white space.
13628 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13629 Use AS_DIRNAME, since I think it's now DOS-friendly.
13630 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13631 Allow "dirname //FOO" to return either / or //, as POSIX allows
13634 2001-10-10 Akim Demaille <akim@epita.fr>
13636 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
13637 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
13640 2001-10-10 Akim Demaille <akim@epita.fr>
13642 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13646 2001-10-10 Akim Demaille <akim@epita.fr>
13648 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

13682 bother with $force since...
13683 * lib/Autom4te/General.pm: does.
13685 2001-10-08 Akim Demaille <akim@epita.fr>
13687 * bin/autoreconf.in: Rewrite in Perl.
13688 * configure.ac: Adjust.

13771 shell does not support LINENO, and if CONFIG_SHELL is unset or
13772 empty, and if we can find a shell that does support LINENO,
13773 then set CONFIG_SHELL to that shell and then re-execute
13774 ourselves with CONFIG_SHELL.
13776 2001-10-05 Paul Eggert <eggert@twinsun.com>
13778 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13779 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13849 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13850 Don't use nested parenthesization. This patch was originally
13851 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13852 but somehow it didn't get incorporated then.
13853 * doc/autoconf.texi (Limitations of Usual Tools):

13856 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13857 Report an error if the size cannot be determined even though
13859 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13860 Check for `expr' arithmetic overflow, and for compilation failure,
13861 and invoke a new argument $4 if either is discovered.
13862 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13863 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13865 2001-09-28 Akim Demaille <akim@epita.fr>
13867 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

14081 * lib/autotest/general.m4: Englishoes.
14082 From Tim Van Holder and Alexey Mahotkin.

14086 * doc/autoconf.texi (Common Shell Constructs): New node,
14087 documenting AS_DIRNAME.
14088 (Limitations of Usual Tools): Refer to it when discussing dirname.
14089 Also, update discussion of POSIX standard to reflect latest draft.

14092 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14094 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14095 Do not pass a first argument with leading '-'
14096 to expr, by parenthesizing initial integers that might be negative.
14098 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14099 now merely checks whether it is an error to pass an argument
14102 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14103 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14104 whether it is a (compile-time) error to pass an argument to
14105 getpgrp. This simpler test supports the revised documentation,
14106 and is all that AC_FUNC_GETPGRP's users really need.
14108 2001-09-18 Akim Demaille <akim@epita.fr>

14122 Add test for AS_BASENAME.
14123 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14124 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14125 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14126 * tests/base.at: Fixed the expected responses. The old ones were
14128 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14129 the documentation claims it should (and how it behaved in 2.13).
14131 2001-09-18 Akim Demaille <akim@epita.fr>
14133 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14134 the AC_CONFIG_COMMANDS invocation.
14135 This also solves the name clash problems.
14136 Don't set the package's ID.
14137 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14138 No longer to be shipped.
14139 (version.in): Remove.

14142 Use `m4_PACKAGE_STRING'.
14143 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14144 the only optional argument is the name of the test suite.
14145 Expect `package.m4' to define the package signature.
14146 * lib/autom4te.in (Autotest): Add `package.m4?'.
14147 * tests/Makefile.am (package.m4): New.
14148 * tests/suite.at: ifnames is a victim.

14153 AC_LIBSOURCE, AC_CONFIG_FILES.

14167 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14168 Always include <stdio.h> and <stdlib.h>. Evaluate
14169 the expression in an extra function before these includes. Call
14170 fprintf "%d" only after ensuring the argument is of type 'int'.
14171 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14173 2001-09-17 Paul Eggert <eggert@twinsun.com>
14175 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14176 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14177 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14178 when they don't exist.
14180 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14181 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14184 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14185 version with the version used by fileutils 4.1, except use
14186 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14189 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

14231 * lib/autotest/general.m4 (AT_INIT): Create and remove
14232 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14233 test suites can cohabit.

14237 * tests/mktests.sh: Don't output banners for empty test files.

14343 2001-09-05 Akim Demaille <akim@epita.fr>
14345 Be ready to handle filenames as stupid as `dnl.at', for if even
14346 the maintainer is dumb enough to do that...
14348 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14349 excellence in M4 quotation: consider `__file__' is active.
14351 And BTW, when invoking m4, pass the --include in the right order:
14354 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

14375 * doc/autoconf.texi (autoscan Invocation): Adjust.
14377 2001-09-05 Akim Demaille <akim@epita.fr>
14379 CVS GNU M4 doesn't like `undefine(undefined)'.
14381 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14382 New, extracted from main.
14383 Use IO::File wherever possible.
14384 (input.m4): Be constant, use -I instead of hard coding $tmp.
14385 Therefore be a quoted heredoc.
14386 Don't invoke `_au_disable', since ac was not loaded, but just

14412 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14414 2001-08-31 Akim Demaille <akim@epita.fr>
14416 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14417 (testsuite Scripts): There is no such thing as `atconfig.in'.
14418 And actually one diagram is missing: test suite runtime.
14420 2001-08-31 Akim Demaille <akim@epita.fr>
14422 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14425 2001-08-31 Akim Demaille <akim@epita.fr>
14427 * bin/autoupdate.in (@include): `installcheck' revealed the path
14428 to m4sugar was lacking!
14430 2001-08-31 Akim Demaille <akim@epita.fr>
14432 * man/Makefile.am (.x.1): We really have to pass
14433 autom4te_perllibdir.

14443 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14444 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14445 Use directly autom4te, not autoconf.

14470 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14471 (autoheader): Pass --force since the test suite goes too fast for
14473 Adjust to the new autoheader messages.

14489 `autoheader: `config.hin' is created'.
14490 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14492 2001-08-31 Akim Demaille <akim@epita.fr>
14494 * bin/autoheader.in: Rewrite in Perl.

14500 Map --localdir, --autoconf-dir onto it.
14501 Forward autom4te's options instead of interpreting them.
14502 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14503 There is no such envvar since the inception of autom4te.cfg.
14504 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14505 * bin/autoupdate.in: Adjust, and perform more control.

14507 * tests/autoconf: Dittowise.
14509 2001-08-31 Akim Demaille <akim@epita.fr>

14525 * lib/Autom4te/General.pm (&find_peer): Remove.
14526 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14527 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14528 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14529 find the executables for it.
14530 * tests/Makefile.am: Major cleanup. Too lazy to document...
14531 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14533 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14534 indeed related to running the test suite, while passing
14535 --autoconf-dir and others is related to running non installed
14536 Autoconf executables. So don't do that, leave it to...
14537 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14538 * tests/autoscan: New.
14539 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14556 Suggested by Paul Eggert.
14558 2001-08-29 Akim Demaille <akim@epita.fr>
14560 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14561 download in a tmp dir.
14563 2001-08-29 Akim Demaille <akim@epita.fr>
14565 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14585 foo=`(command) 2>/dev/null`

14736 the name of the directory they're in, instead of the filename,

14825 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
14826 * NEWS, README, README-alpha, TODO, tests/README: This package is
14827 `Autoconf', not `autoconf' (the executable).
14829 2001-08-20 Akim Demaille <akim@epita.fr>
14831 Info readers seem to need `Index' in the index node title :(
14833 * doc/autoconf.texi: Reverse the 2001-08-15 change which
14834 simplified index node names.

14883 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
14884 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

14947 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

14965 * doc/autoconf.texi: Work around Texinfo buglets.
14966 (Transformation Rules): One example is enough, users are expected
14967 to have their brains on. And BTW, use DESTDIR.
14968 (dvar): New macro. Use it.
14970 2001-08-17 Akim Demaille <akim@epita.fr>
14972 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15025 autom4te.cache (it's a directory, not a file.
15026 * Makefile.am: Ditto (but maintainer-clean-local).
15028 2001-08-15 Akim Demaille <akim@epita.fr>
15030 * bin/autom4te.in (@m4_warning): New.
15031 (&handle_m4): Use it.
15032 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15033 warnings are issued at each run.
15034 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15035 is in the src tree.
15037 2001-08-15 Akim Demaille <akim@epita.fr>
15039 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15040 don't waste time running `autoupdate --version' works.
15041 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15043 2001-08-13 Akim Demaille <akim@epita.fr>

15102 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15104 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15105 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15106 * doc/autoconf.texi (C Compiler Characteristics): Update
15107 documentation for AC_C_BIGENDIAN.
15109 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15111 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15112 magic values from an object file when cross-compiling.
15113 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15115 2001-08-10 Akim Demaille <akim@epita.fr>
15117 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15119 Suggested by Russ Allbery.
15121 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15123 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15124 current $prefix to the sub-configures.
15126 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15128 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15129 extension (needed on BeOS). Reported by Guido van Rossum.
15131 2001-08-09 Akim Demaille <akim@epita.fr>
15133 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15135 2001-08-07 Akim Demaille <akim@epita.fr>
15137 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15139 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15140 No need to remove the files before and after the each test, before
15141 each test and at the end of the suite is enough.
15142 Display only the children `times', not the shell's.
15143 If the test failed or was skipped, at-times is not available.
15145 2001-08-07 Akim Demaille <akim@epita.fr>
15147 Always produce testsuite.log, including when there are no
15148 failures. This helps getting information on skipped tests, and
15149 duration of the tests. Err, implement the latter btw.
15151 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15152 Dump information on the first run of each test.
15153 (AT_CLEANUP): Create `at-times' containing the duration of the
15156 2001-08-07 Akim Demaille <akim@epita.fr>
15158 The use of `dumpstat' revealed that `len' was used although it
15159 should not. m4_text_wrap was using it, but in the Autoconf world
15160 where it is legal. Hence (i) test M4sh in its own world, not
15161 Autoconf's, and (ii), ahem, fix the bug :)
15163 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15164 does not like `' instead of [].
15165 (AT_INIT): Forbid `^_?AT_'.
15166 And don't output such tokens.
15167 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15168 `script.as', and `autom4te.cache'.
15169 Remove `empty' and `macro' which are no longer used.
15170 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15171 * tests/m4sugar.at: Use it.
15172 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15174 2001-08-07 Akim Demaille <akim@epita.fr>
15176 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15178 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15180 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15182 2001-08-04 Akim Demaille <akim@epita.fr>
15184 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15185 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15187 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15188 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15189 (AC_F77_MAIN): Likewise.
15191 2001-08-04 Akim Demaille <akim@epita.fr>
15193 Don't rely on M4sugar outputting the patterns in files, since we
15194 might process the output _without_ running m4, hence without these
15197 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15198 * bin/autom4te.in (@Request::includes): Remove, unused.
15199 (@Request::source): Rename as...
15200 (@Request::input): this.
15201 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15202 (&handle_output): Fetch the patterns from the traces.
15203 `$forbidden' and `$allowed' are constant: use m//o.
15204 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15205 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15207 2001-08-04 Akim Demaille <akim@epita.fr>
15209 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15210 autoconf', i.e., in addition to caching traces, cache the output.
15212 * bin/autom4te.in (Request::cache): Rename as...
15213 (Request::id): this.
15214 ($cache, $icache, $tcache, $ocache): New.
15215 (&handle_m4): Save M4 output in the cache instead of $tmp.
15216 (&handle_output): Adjust.
15217 (&up_to_date_p): Check that the output cache is up to date too.
15218 (top level): Run `&handle_m4' iff force or the cache is invalid.
15219 Run `&handle_output' if the output cache is more recent.
15221 2001-08-04 Akim Demaille <akim@epita.fr>
15223 * bin/autom4te.in ($force): New.
15224 (&parse_args, &print_usage): -f, --force is a new option.
15225 (&handle_output): CPP directives might have spaces after `#'.
15226 (&parse_args): The first file only can be frozen.
15228 2001-08-04 Akim Demaille <akim@epita.fr>
15230 Don't let autom4te compute the `include' traces several times:
15231 first check that the trace cache file is up to date, and then
15232 compare its timestamp with that of the output.
15234 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15235 the preamble. Don't require 5.005 as Autom4te::General does it,
15236 and better yet (use `use', not `require'!).
15237 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15238 Class::Struct as Autom4te::Struct.
15239 * lib/Autom4te/General.pm (File::stat): Use it.
15240 (&mtime): New, export it.
15241 * bin/autom4te.in: Use it.
15242 Declare `$req' is invalid if it is outdated.
15243 Don't declare it valid before saving it if something went wrong.
15245 2001-08-04 Akim Demaille <akim@epita.fr>
15247 Autom4te shall not encode Autoconf data, and preselecting traces
15248 must be proposed to the users.
15250 * bin/autom4te.in (@required_trace): Remove.
15252 (&parse_args, &print_usage): -p, --preselect is a new option.
15253 (&up_to_date_p): Adjust.

15256 2001-08-04 Akim Demaille <akim@epita.fr>
15258 * tests/tools.at (autoconf --trace: user macros): Check traces on
15259 macros invoked without arguments, and macros invoked with multiple

15264 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15267 2001-08-03 Akim Demaille <akim@epita.fr>
15269 * bin/autoconf.in ($@): Work around the usual sh bug.
15272 2001-08-03 Akim Demaille <akim@epita.fr>
