1050 do not go back to the build tree for the next config subdir.
1051 * tests/torture.at (Deep Package): Extend test to contain two
1052 config subdirs on the top level.
1054 Fix parallel `maintainer-check'.
1055 * Makefile.am (maintainer-check-tests): Depend on `all'.
1056 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1057 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1059 (maintainer-check): Serialize the testsuite runs.
1061 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
1062 in feature string for --enable/--with. Convert to underscore
1065 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
1066 `install -c file1 file2 dir' works.
1067 * doc/autoconf.texi (Particular Programs): Document this.
1070 2008-01-21 Eric Blake <ebb9@byu.net>
1072 Improve documentation about default include directives.
1073 * doc/autoconf.texi (Generic Headers, Generic Declarations)
1074 (Generic Structures, Generic Types)
1075 (Generic Compiler Characteristics): Add links to
1076 AC_INCLUDES_DEFAULT.
1077 Reported by Reuben Thomas.
1079 2008-01-15 Eric Blake <ebb9@byu.net>
1081 * lib/m4sugar/m4sugar.m4 (m4_qlen): Use fewer macros.
1083 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1085 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1086 check_SCRIPTS. Building the wrappers for `all' allows help2man
1087 to use them for the manpages.
1088 Report by Benoit Sigoure.
1090 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1092 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1094 Fix some write failure cases in Autotest.
1095 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
1096 upon write failures for --help, --version, --list.
1097 Guard against write failures for intermediate created scripts.
1098 <at_func_create_debugging_script>: Do not make the debugging
1099 script executable if it is not complete.
1101 2007-12-12 Eric Blake <ebb9@byu.net>
1103 Fix thinko in earlier patch - m4_join isn't defined yet.
1104 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1105 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1106 (m4_require): Use m4_do, not m4_join.
1108 Fix some whitespace tests on cygwin.
1109 * tests/tools.at (autom4te and whitespace in file names): Restore
1110 font-lock. Create $TMPDIR before it might be used.
1112 Fix spurious testsuite failure with M4 1.4.11.
1113 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1115 Optimize AC_REQUIRE.
1116 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1117 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1118 (m4_require): Avoid extra macro calls.
1120 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 * tests/torture.at (srcdir): Fix quoting.
1124 Do not pass top_srcdir to configure scripts in testsuite.
1125 * tests/autotest.at (srcdir propagation): Copy install-sh to
1127 (my only test): Drop setting of `top_srcdir'.
1128 * tests/base.at (Input/Output): Likewise.
1129 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1130 config.guess, and config.sub to test source tree.
1131 Drop AC_CONFIG_AUX_DIR setting.
1132 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1133 * tests/torture.at (Substitute a 2000-byte string): Drop
1134 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1135 (Substitute a newline, datarootdir workaround): Likewise.
1136 (Define a newline): Adjust for linenumber changes in configure.ac.
1137 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1139 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1140 if `pwd` contains whitespace.
1142 Quote $abs_top_srcdir in tests.
1143 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1144 * tests/tools.at (Syntax of the shell scripts): Likewise.
1146 * tests/m4sh.at (LINENO): Quote $0.
1148 Fix testsuite program wrapper for whitespace in `pwd`.
1149 The problem here is that the usual mantra is that command
1150 variables can contain arguments, thus we cannot just escape
1151 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1152 $top_builddir/tests directory early in $PATH, so that the
1153 wrappers are found by their plain name.
1154 * tests/wrapper.as: Put $testdir early in $PATH.
1155 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1157 Proper config.status --file/--header and $srcdir escaping.
1158 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1159 characters in $ac_file_inputs.
1160 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1162 * tests/torture.at (datarootdir workaround): Adjust.
1163 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1165 Fix Autotest for whitespace in `pwd`.
1166 * lib/autotest/general.m4 (AT_INIT)
1167 <at_func_create_debugging_script, Driver Loop>:
1168 Quote $at_group_dir.
1169 * tests/autotest.at (whitespace in absolute testdir): New test.
1171 * lib/autom4te.in: Quote @datadir@.
1173 Proper file name escaping in Autoconf programs and Perl modules.
1174 This includes escaping of characters special to the shell
1175 as well as special to Perl, e.g., leading `<' or `>'.
1176 For example, when $file starts with `>', `open ">$file"'
1177 wrongly tries to append to a different file.
1178 * bin/autoconf.as: Fix quoting for autom4te options.
1179 * lib/Autom4te/General.pm (shell_quote): New function, taken
1180 from coreutils, written by Jim Meyering.
1182 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1184 * bin/autoreconf.in (parse_args): Likewise.
1185 * bin/autoscan.in (main): Likewise.
1186 * bin/autoupdate.in (main): Likewise.
1187 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1188 * bin/ifnames.in: Likewise, XFile usage fixes.
1189 * tests/tools.at (autom4te and whitespace in file names): Extend
1190 test. Test twice, with special characters allowed on w32, and the
1191 rest. Test leading and trailing whitespace, for `open_quote'.
1192 (autotools and whitespace in file names): New, analogous test.
1193 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1194 by Russ Allbery and Eric Blake.
1197 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1198 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1199 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1200 (update_file, contents): Use it.
1202 * Makefile.am (autom4te-update): Rewrite for git.
1204 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1206 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1208 Fix copyright years.
1209 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1210 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1212 2007-12-04 Eric Blake <ebb9@byu.net>
1214 Manually resync with gnulib, since 'make cvs-update' no longer works.
1215 * build-aux/config.guess: New upstream version.
1216 * build-aux/config.sub: Likewise.
1218 When using older automake, don't downgrade build-aux/texinfo.tex.
1219 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1220 * doc/Makefile.am (TEXINFO_TEX): Add.
1222 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1224 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1225 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1226 #undef as this runs afoul of our new way of creating config.h.
1227 Problem reported by Jim Meyering in
1228 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1230 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1232 Fix autom4te for unusual characters in input file names.
1233 * bin/autom4te.in (files_to_options): Quote active characters
1235 * tests/tools.at (autom4te and white space in file names):
1238 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1239 Document that Tru64 awk always splits $0.
1241 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1243 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1244 `#AT_STOP_...' line at the end of each test.
1246 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1248 * lib/autotest/general.m4 (AT_INIT): For awk line number
1249 extraction script, ensure `$at_group' has a defined value
1250 even for the empty set, and properly quote its usage inside
1253 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1255 * doc/autoconf.texi (Shell Functions): New chapter. Document
1256 IRIX sh $0 issue in functions, move content from ...
1257 (Portable Shell): ... here.
1258 (Shell Script Compiler): Note that shell functions are not
1259 totally unportable any more.
1261 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1262 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1264 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1265 extracting the line numbers of the last needed test.
1267 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1269 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1272 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1274 Fix IRIX testsuite debugging failures: $0 in functions.
1275 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1276 Do not use $0 inside a function, as IRIX sh will set that to the
1277 function name rather than the script invocation name.
1279 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1280 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1282 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1283 to extract test scripts.
1284 (AT_INIT): Extract and cache test script line numbers.
1286 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1289 subsequent fixups; the awk -> here-document conversion trashes
1290 performance too much with AIX sh.
1292 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1294 * tests/local.at: Do not test m4, perl with AT_TESTED.
1296 Diagnose and guard against write errors dealing with config.status.
1297 The general idea is this: all write failures from `configure'
1298 writing `config.status' are indicated by $ac_write_error, which
1299 is only checked at the end. This is safe because config.status
1300 code is not executed before the file is complete. Other write
1301 failures, be they inside config.status, or in sub shell/awk
1302 scripts spawned from configure or config.status, typically need
1303 earlier checking, as their results are used right afterwards.
1304 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1305 before writing config.status, check afterwards.
1306 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1307 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1308 Set `ac_write_error' for write failures to config.status. Barf
1309 upon write failures to temporary files.
1310 Adjust note about closing and reopening the here-document.
1311 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1312 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1313 reopening the here-document.
1314 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1315 Ensure `ac_write_error' does not escape into config.status.
1316 Also, add a couple of code paths not yet exercised in the test
1317 suite: a config file with input from stdin, and a config header
1319 Suggestion for catching write errors by Bruno Haible.
1321 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1323 Avoid error with Tru64 awk and testsuite lines with many words.
1324 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1325 reads the testsuite, set the field separator to an unusual value,
1326 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1327 even splits the input if $i, i>0, was never accessed in the script.
1329 Revert 2007-10-17 change.
1330 * TODO: Multiline args in config files and headers mean something
1331 different and are not fixed, see

1337 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1339 AC_*_TOOL does not canonicalize the prefix
1340 * doc/autoconf.texi (Generic Programs): Do not say that
1341 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1343 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1345 Diagnose write errors in config.status instantiations.
1346 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1347 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1349 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1365 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1366 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1368 * lib/autotest/general.m4 (at_func_test): Remove.
1369 (AT_INIT): Pre-extract test groups into separate files.
1370 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1371 Remove at-test-source files together with the $at_group_dir.
1372 * tests/autotest.at (Long test source lines): New test.

1387 * lib/autoconf/status.m4: Fix a couple of comment typos.
1389 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1391 2007-11-13 Jim Meyering <meyering@redhat.com>
1393 Clean up the rule to create "expr".
1394 * tests/Makefile.am (expr): Don't redirect directly to target.
1395 Redirect just once, not for each echo statement.
1396 Use $@, not literal "expr".
1398 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1400 Don't worry about preprocessor when testing long long.
1401 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1402 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1403 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1404 These no longer check for preprocessor flaws.
1405 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1406 Do not check for preprocessor flaws.
1408 2007-11-13 Jim Meyering <meyering@redhat.com>
1410 Adapt dependencies, now that a version change doesn't modify configure.ac
1411 * GNUmakefile: Remove "make clean" kludge.

1414 Don't redirect directly to target.

1420 ":;{" shorthand as in previous patch.
1422 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1424 * doc/autoconf.texi (Limitations of Builtins): Document problem
1425 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1427 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1428 Use ":;{" shorthand.
1429 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1431 2007-11-12 Jim Meyering <meyering@redhat.com>
1433 Add more non-srcdir build support.
1434 * GNUmakefile (dummy): Split a long line.
1435 Add -v option to autoreconf invocation.
1437 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1438 * GNUmakefile (dummy): Remove INSTALL.
1440 Remove racy commands to build scripts in bin/ and tests/.
1441 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1442 are guaranteed to be built, remove the rules that tried to build
1443 them. Before, with a parallel build, these rules could lead to
1444 two processes writing tests/wrapper.in concurrently.
1446 Build in man/ only *after* building in bin/ and tests/.
1447 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1448 in both bin/ and tests/.
1450 Accommodate non-srcdir build-from-checkout.
1451 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1452 Use git's --git-dir=$srcdir/.git option.
1453 Add quotes, in case tarball_version_file contains shell meta-characters.
1454 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1455 * configure.ac: Pass "." to git-version-gen.
1457 Avoid spurious test failures due to version skew.
1458 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1487 Ignore configure --help* errors due to LINENO-impaired shells.
1488 * tests/torture.at (Configuring subdirectories, Deep Package):
1489 In the --help* tests in read-only trees, make `.' temporarily
1490 writable again for the `stderr' file, and ignore errors due to
1491 the attempt to write configure.lineno.
1492 Report by Patrick Welche.
1494 2007-11-10 Jim Meyering <meyering@redhat.com>
1496 Generate package.m4 in build-dir, not srcdir.
1497 * tests/Makefile.am (package.m4): Adjust target.
1498 Don't redirect directly to $@.
1499 (CLEANFILES): Add package.m4.
1500 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1502 When running $(AUTOTEST), search "." before searching $(srcdir).
1504 Avoid a race condition that would make parallel "distclean" fail.
1505 * tests/Makefile.am (distclean-generic): Replace the default,
1506 automake-provided rule with an identical one, but with an additional
1507 dependency on distclean-local. Simply adding the dependency would
1508 cause automake not to emit the rule at all.
1509 * BUGS: Building with -jN works, now.
1511 Distribute git-version-gen.
1512 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1513 since GNUmakefile is distributed, and requires it for dist* rules.
1515 Remove two more generated files from version control.
1516 * INSTALL: Remove generated file.
1517 * lib/autoscan/autoscan.list: Remove generated file.
1519 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1521 * GNUmakefile (PATH): Remove stray apostrophes; they become
1522 part of PATH, which isn't wanted here.
1524 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1526 New config files output variable `top_build_prefix'.

1529 * doc/autoconf.texi (Preset Output Variables): Document it.
1531 Report by Bob Friesenhahn.
1533 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1534 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1535 function, to parametrize arithmetic with expr vs. the shell.
1536 Use it where possible.
1537 Suggestion by Benoit Sigoure.

1646 Make inter-release --version output more useful.
1648 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1649 which indicates that it is built using the 19th change set
1650 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1651 is a prefix of the commit SHA1.
1652 * build-aux/git-version-gen: New file.

1662 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1663 git-version-gen doesn't match $(VERSION), but only for dist targets.

1736 Fix config header generation with AIX awk.
1737 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1738 script, use helper array D_is_set, as `" 0"' does not evaluate

3021 nonstandard grep R.E. escape sequences.
3023 2007-03-17 Jim Meyering <jim@meyering.net>
3025 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3026 (Limitations of Usual Tools): Also list \< and \>, and mention that
3027 HP-UX's grep, like the one from Solaris, does not support that syntax.
3029 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3031 * doc/autoconf.texi (Specifying Names): `--host' does not
3032 change the build type.
3034 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3036 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3037 suggests AC_CONFIG_HEADERS.
3038 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

3047 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3048 universal binaries. Problem reported by Elias Pipping.
3050 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3052 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3053 * doc/autoconf.texi (C Compiler): Document this. There is a new
3054 extra argument ACTION-IF-UNIVERSAL.
3055 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3056 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3057 Reindent for sanity's sake.
3059 2007-02-24 Eric Blake <ebb9@byu.net>
3061 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3063 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3064 * lib/autotest/general.m4 (AT_INIT): Likewise.

3067 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3069 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3070 status of rm so we know when it failed.
3071 If cleaning of test dir failed before running the test, warn.
3072 Output the line separator in verbose mode before the warning
3073 to make clear the warning belongs to the following test.
3075 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3077 * doc/autoconf.texi (Parentheses): Mention problem with (( in

3096 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
3098 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3100 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3101 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3102 will not wait for input with a script containing only a BEGIN

3136 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3138 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3139 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3140 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3141 substitution will still be done by the special code.
3142 Report by Jim Meyering.

3156 Test all 8 bit non-NUL characters.
3157 Report against Automake by Patrick Welche.
3159 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3161 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3163 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3165 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3166 early on the reader side, drop stderr of the input to avoid
3167 `broken pipe' error output; this may happen even with shell
3168 builtin `echo' of some bash versions. Reports by Ian Macdonald
3169 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3171 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3173 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3174 separate items of `ac_user_opts', to avoid long lines.
3175 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3177 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3179 * doc/autoconf.texi: Fix some typos.
3181 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3183 Fix some wording problems noted by Paolo Bonzini in:
3184 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3185 * doc/autoconf.texi (Signed Overflow Examples): Give more
3186 discussion about the allow_superuser_privileges example,
3187 and change it a bit to make things clearer.
3188 (Optimization and Wraparound): Clarify whether the compiler
3189 will generate an infinite loop for the example derived from
3190 Autoconf's mktime test.
3191 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3192 Also, clarify unsigned multiplication overflow.
3194 2007-01-04 Eric Blake <ebb9@byu.net>
3196 * bin/Makefile.am (RELEASE_YEAR): New macro.
3197 (edit): Use it to supply correct copyright year to scripts.
3198 * bin/autoconf.as (version): Use it.
3199 * bin/autoheader.in ($version): Likewise.
3200 * bin/autom4te.in ($version): Likewise.
3201 * bin/autoreconf.in ($version): Likewise.
3202 * bin/autoscan.in ($version): Likewise.
3203 * bin/autoupdate.in ($version): Likewise.
3204 * bin/ifnames.in ($version): Likewise.
3206 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3208 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3209 feedback. The most important changes document what happens when
3210 you convert an out-of-range value to a signed integer type, and
3211 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3214 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3215 rewrite, taking notions from the recent discussion on the gcc and
3216 autoconf mailing lists; please see
3217 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3218 and follow the many links.
3219 (Integer Overflow Basics, Signed Overflow Examples):
3220 (Optimization and Wraparound, Signed Overflow Advice):
3221 (Signed Integer Division): New sections.
3223 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3225 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3226 preprocessor macro arguments in traced name.
3227 * doc/autoconf.texi (Defining symbols): Document longstanding
3228 support for AC_DEFINE-ing macros with arguments, and document
3229 behavior when the same variable has multiple AC_DEFINEs.
3230 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3231 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3232 macros directly, giving much shorter and simpler code.
3234 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3236 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3237 space before "$ac_configure_args" to prevent a 'config.status
3238 --recheck' failure if ac_configure_args doesn't contain a leading
3239 space. This works around a problem with the XEmacs configure.ac,
3240 which uses the (undocumented) ac_configure_args variable
3241 inconsistently with Autoconf.
3243 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3245 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3246 Include <limits.h>, and use its INT_MAX to rewrite the
3247 j loop so that it does not overflow 'int'. Problem reported by
3249 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3250 Play it safe by shifting left by 1 rather than multiplying by 2,
3251 as GCC is less likely to optimize this away when the value
3252 is signed (when it assumes overflow leads to undefined behavior).
3253 Also, don't assume time_t uses two's complement.
3255 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3257 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3258 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3259 dumps core on it. Report by Tim Rice.
3261 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3263 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3264 --disable-option-checking to --help output even when
3265 AC_PRESERVE_HELP_ORDER is not used.
3266 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3267 --with argument, rather than argument with [-.] replaced by
3269 * NEWS: Fix typo in previous change; the news was in the
3272 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3274 * NEWS: Warnings are now generated by default for unknown
3275 --enable-* and --with-* options.
3276 * doc/autoconf.texi (Option Checking): Renamed from
3277 (Configure Option Checking). Tighten up the wording a bit.
3278 (External Software, Package Options): Cross-reference to Option
3279 Checking, and use this to shorten our section.
3280 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3281 "$x" to test "x$foo" != x.
3282 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3283 Don't warn if $enable_option_checking is "no".
3284 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3285 ac_unrecognized_opts to the empty string.
3286 Don't echo the unrecognized opts, as this might mishandle
3287 backslashes or leading -.
3288 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3289 usage next to the other --disable-FEATURE options in the
3292 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3294 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3295 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3296 Print warning for unrecognized --with and --enable options
3297 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3298 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3299 Disable option checking when subdirs are configured.
3300 (AC_OUTPUT): If warnings are enabled, print warning about
3301 unrecognized --with and --enable options at the end of
3302 the configure output (as well as at the beginning).
3303 * doc/autoconf.texi (Option Checking): New node.
3304 Document new option warning functionality.
3306 2006-12-16 Eric Blake <ebb9@byu.net>
3308 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3309 * NEWS: Start news for current version.
3311 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3313 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3314 Define HAVE_GETMNTENT to 1, not to the empty string.
3315 Problem originally reported by Jochen Friedrich in
3316 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3318 This change prompted by a problem report by Andrey Simonenko in
3319 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3320 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3321 object-like macros only, in the traditional portable character
3323 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3324 Warn about attempts to define things that are not identifiers.
3325 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3326 awful hack that AC_DEFINEd macro names containing parentheses.
3328 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3330 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3331 too drastic, even if Texinfo in theory requires it for info mode.
3333 (config.status Invocation): Renamed back from Recreating a
3335 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3336 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3338 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3340 * NEWS: Version 2.61a.
3342 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3343 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3345 * NEWS: Document changes with echo and printf, and the lack
3346 of limits on the total size of multi-line values of substituted
3347 variables, and the AC_FUNC_FSEEKO fix.
3349 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3351 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3352 Writing configure.ac.
3353 (Autoconf Input Layout): Renamed from configure.ac Layout.
3354 (Recreating a Configuration): Renamed from config.status Invocation.
3355 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3356 (acconfig Header): Renamed from acconfig.h.
3357 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3358 (Writing Testsuites): Renamed from Writing testsuite.at.
3359 (Autom4te Cache): Renamed from autom4te.cache.
3361 * BUGS: Remove mention of VPATH problem, since it's now documented
3362 not to be a bug in the Autoconf build procedure itself, but rather
3363 a problem with the proprietary `make' programs.
3365 * doc/autoconf.texi (Build Directories): Add a cross reference
3368 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3369 * doc/standards.texi: Sync from gnulib.
3371 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3372 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3373 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3374 generated automatically.
3376 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3378 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3379 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3380 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3382 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3384 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3385 `CEOF$ac_eof' special marker, the awk script cannot contain a
3386 line matching `^CEOF', so this is not needed any more.
3387 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3388 special marker in the test.
3390 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3392 * tests/tools.at (autom4te preselections): Use `find -newer';
3393 remove one of the sleeps.
3395 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3396 more readable, using ...
3397 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3399 * doc/autoconf.texi (autoheader Invocation): Do not double-
3400 quote the parameter of `AH_BOTTOM' in the example.
3402 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3404 * doc/autoconf.texi (Configuration Headers): Remove the
3405 example with multiple input files.
3406 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3407 multiple input files.
3409 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3411 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3412 creating the awk substitution script, handle one input line at a
3413 time, so that the maximum length of a substituted (multi-line)
3414 value is not limited by the size of the sed pattern space.
3415 The trade-off is a slightly repetitive sed script.
3416 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3417 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3418 * tests/torture.at (Substitute a 2000-byte string): Increase the
3419 test with several long lines, they should not be caught by sed
3422 * tests/tools.at (autom4te preselections): New test, to flag
3423 entries missing from autom4te.cfg.
3424 Report by David Byron <dbyron@hheld.com>.
3426 * tests/torture.at (Substitute a 2000-byte string): Actually use
3427 AC_PROG_AWK, so the last change works as intended.
3428 (Substitute and define special characters): Likewise.
3429 (Substitute a newline): Likewise.
3431 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3432 instead of `awk' consistently.
3433 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3434 * tests/torture.at (Torturing config.status): Test both the
3435 result of AC_PROG_AWK and plain awk.
3436 (Substitute a 2000-byte string): Likewise.
3437 (Substitute and define special characters): Likewise.
3438 (Substitute a newline): Likewise.
3440 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3442 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3443 can be assigned to a function pointer. Problem reported by
3444 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3445 part of a patch by Ralf Wildenhues in that same bug report.
3447 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3449 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3450 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3452 2006-12-01 Eric Blake <ebb9@byu.net>
3454 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3455 cross-compiling from cygwin to mingw.
3456 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3457 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3458 to lib/autoconf/c.m4.
3460 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3462 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3463 string for more reliable failure. Wrap the entire test that
3464 causes the broken Solaris printf to dump core, in a subshell,
3465 so the segmentation fault message is reliably suppressed.
3466 Fix shell expansion errors by using /usr/ucb/echo always;
3467 avoid an error on systems without it by another subshell.
3468 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3469 subshell-$as_echo to `as_echo', for better error message.
3471 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3473 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3474 `BASH_SOURCE' contain a newline, set them to empty, as they may
3477 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3479 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3480 years and is too hard to maintain now. The last straw was
3481 reported by Jerker Baeck in
3482 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3483 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3484 * doc/autoconf.texi (Particular Functions): Move
3485 AC_FUNC_SETVBUF_REVERSED from here...
3486 (Obsolete Macros): ... to here. Say that it does nothing now.
3487 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3488 Turn into (almost) a no-op.
3490 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3492 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.

3526 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3527 in the sed script that mangles the awk script: delete up to the
3528 first exclamation mark only.
3529 * tests/torture.at (Substitute and define special characters):
3532 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3534 Rewrite config files generation: avoid quadratic growth in
3535 the number of substituted variables by using awk instead of sed
3536 for the bulk of the substitutions.
3537 * NEWS: Mention this.
3538 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3539 forbidden in the output (and thus input) file.
3540 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3541 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3542 generate just one large awk script for substitutions,
3543 eliminating much of the earlier complexity, while adding some
3544 new complexity. Only expand the substitution templates at
3545 configure time, for smaller configure script size. If
3546 _AC_SUBST_FILES are used, test 'awk' for working getline support
3547 at config.status time. If absent, interpolate through the
3548 shell. The awk script was written with much help
3549 from Paolo Bonzini and Paul Eggert.

3556 substitute a line with 1000 words, and a variable with several
3558 (Substitute and define special characters): Test awk special
3559 characters, and put substitution input strings `@foo@' in the
3560 output, to test that no recursion happens; test several other
3561 combinations from Paolo Bonzini.

3565 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3566 that replaced echo with AS_ECHO where this wasn't necessary.
3567 Problem reportd by Ralf Wildenhues.
3568 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3569 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3570 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.

3578 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3579 that traditional Awk lacks 3-arg "split". It has it.
3580 Mention that FS must be a single character, and a few other
3581 99-byte limits of traditional Awk.
3582 Mention that if (i in a) doesn't work with traditional Awk.

3590 (Single-quote-newline-BS-newline in command):
3591 Use printf '%s\n' instead of echo, for portability to hosts
3592 where echo interprets backslashes. This will break on hosts
3593 that lack printf, but for now let's assume all such hosts
3594 are dead (if not, we should get reports of test failures).
3596 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3598 'echo' has some portability problems, when given a first argument
3599 with a leading '-', or when given any argument containing '\'.

3780 and Stepan Kasal <kasal@ucw.cz>
3782 Handle special characters in test case titles correctly.
3783 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3785 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3786 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3787 argument. Extend to check titles printed by ./micro-suite and
3788 ./micro-suite -l and the title in micro-suite.log.
3789 (Backquote in a test title,
3790 Single-quote in a test title,
3791 Double-quote in a test title): Don't expect failure anymore.

3793 backslash so that Bourne shells might actually see it as an escape
3795 (Brackets in a test title,

3804 * tests/torture.at (#define header templates): M4-quote this title in
3805 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3806 The visible effect was a stray [] in the testsuite output.
3808 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3813 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3815 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3816 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3817 5363) simply issues a warning when dividing by zero at compile
3818 time. Problem reported by Elias Pipping.
3820 2006-10-26 Eric Blake <ebb9@byu.net>
3823 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3824 show effect on macros that expand with commas.

3851 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3852 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3853 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3854 reported by Nelson H. F. Beebe for Coreutils 6.4.
3856 * tests/tools.at (autoconf --trace: user macros): Remove test
3857 for tracing multiline macros, since m4 1.4.7a uses a different
3858 way to number lines. Problem reported by Ralf Wildenhues.
3860 2006-10-24 Stepan Kasal <kasal@ucw.cz>

3934 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3936 (Imported from Automake.)
3937 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3938 which incorrectly sets the mode of an existing destination
3939 directory. In some cases the unpatched install-sh could do the
3940 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3941 system. We hope this is rare in practice, but it's clearly worth
3942 fixing. Problem reported by Alex Unleashed in
3943 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3944 Also, don't bother to check for -m bugs unless we're using -m;

4017 the NonStop platform.
4018 * doc/autoconf.texi (Posix Variants): Likewise.
4019 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4021 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4022 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4023 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4024 Use a better substitute, by inspecting the output of "ls"
4025 rather than just using ":".
4026 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4027 rather than AS_EXECUTABLE_P, since we needn't worry about
4028 non-regular files here.
4030 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4031 due to configuration hassles with this. See Tonya Underwood's report
4032 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4033 * doc/autoconf.texi (Special Shell Variables): Likewise.

4055 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4056 comment about ac_cpp_err; it was incorrect, and anyway
4057 ac_cpp_err is being removed below.
4058 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4059 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4060 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4062 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4063 with werror_flag and conftest.err and so forth. This is more
4064 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4065 and anyway the user shouldn't normally want to see this gorp logged.
4066 Problem reported by Ralf Wildenhues.
4067 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4068 empty, not 'no', since the rest of the code uses 'test -z'.
4070 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4072 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4073 Use a single call to AC_DO_TOKENS rather than multiple, for
4075 (_AC_LINK_IFELSE): Test that resulting file is executable.
4076 Problem reported by mwoehlke in
4077 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4079 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4080 than creating a file to use with test -x; this is much faster.
4082 2006-10-02 Bruno Haible <bruno@clisp.org>
4084 * lib/autom4te.in (Automake-preselections): Add
4085 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4087 2006-09-27 Stepan Kasal <kasal@ucw.cz>

4092 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4094 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4095 fseeko testing program twice; just use the earlier result.
4096 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4097 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4098 still doesn't let the program compile.

4102 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4103 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4104 include it, without including anything else.

4111 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4112 `error.h', and include it, for a `error_at_line' prototype.
4113 Use a nonempty format string in the link test.
4114 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4115 for a declaration of wait3.

4120 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4121 can apply to constants too, and that it checks for macro defns.
4122 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4123 and simply cast the identifier to void. This handles structure
4124 values. Problem reported by Ralf Wildenhues.

4214 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

4218 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4219 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4220 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.

4339 broken lex libraries like native ia64-hp-hpux11.22; see
4340 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4468 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4469 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4470 -Wundef -Werror". Problem reported by David Fang in
4471 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

4494 problems with arg script text that doesn't end in newline, and
4495 with '-e a...'. Problems reported by Ralf Wildenhues.
4497 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4499 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
4500 check for libXt by a check for libX11.

4518 the compiler created a file "b.out" when it didn't create anything
4520 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
4521 Discard stderr too, when invoking the test script.

4531 less skeptical about "volatile", after discussion with
4532 Bruno Haible on bug-gnulib.
4533 (Limitations of Usual Tools): Warn about sed stripping
4534 leading white space from text. From Bruno Haible.
4536 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4538 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4539 compiler complains about it, even if things works after the
4540 complaint. Problem reported by Peter O'Gorman.
4542 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4543 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

4546 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4548 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4549 after -R regardless of host. Patrick Welche reports that this

4560 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4561 under AC_C_VOLATILE.
4562 (Volatile Objects): Be a little less skeptical about what
4563 "volatile" means. Derived from thoughts by Ben Pfaff in
4564 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4566 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4570 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4572 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4573 more globally, since the 2006-06-30 patch didn't suffice. Problem
4574 reported by Keith Marshall. Also, don't bother with builddir2,
4575 since it shouldn't be needed any more.
4577 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4594 * NEWS: Document previous change.
4596 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4598 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4599 Require that long long int be at least 64 bits wide. C99 requires
4600 this and enough programs depend on it so we should check for it.
4601 Bruno Haible reports in
4602 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4603 that long long int is 32 bits wide with some nonstandard compilers.
4604 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4606 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4608 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4609 to a nonexistent file, so that we don't have to worry about
4610 a local site configuration that doesn't use /usr/local.
4611 Problem reported by Keith Marshall in
4612 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4614 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4616 * doc/autoconf.texi: Be more consistent about using @acronym with
4617 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4618 quite right (it talked about "OSF/Tru64", even though the
4619 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4620 and it even mentioned "OSF 4"!) and at this point there's little
4621 reason to talk about OSF any more, since it died in 1994.
4622 (Specific Compiler Characteristics): Simplify example of
4623 negative-size array.
4624 (File Descriptors): Reorder to make the text flow better.
4625 Remove joke about "appreciate the various levels"; I didn't get it.
4626 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4627 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4628 (File Descriptors, Limitations of Usual Tools):
4629 Tone down the advice against renaming or removing open files.
4630 (Limitations of Usual Tools): Add a new section, on 'rm'.
4632 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4634 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4635 -lXt in LIBS, idea from Karsten Hopp; this was due since
4638 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4639 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4640 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4641 (which belong to Xt, not X itself). See Debian bug 327655.
4643 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4645 * configure.ac (AC_INIT): Bump to 2.60a.

4665 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4667 * doc/autoconf.texi (Changed Directory Variables): New node,
4668 to document the whole `datarootdir' business a bit better.
4670 * tests/torture.at (datarootdir workaround): Extend test.
4671 Prompted by report by Alexandre Julliard.
4673 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4675 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4676 when using default mode of IBM C 6 for AIX. Problem and two-line
4677 fix reported by Larry Jones.
4679 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4681 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4682 about literal '${datarootdir}' if a definition is found in the
4685 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4687 * NEWS: Use "M4" rather than "m4" when appropriate.
4688 Problem reported by Eric Blake.
4689 * doc/autoconf.texi: Likewise.
4690 Use @acronym around BSD, GCC, and GNU when appropriate.
4691 (Why GNU M4): Renamed from "Why GNU m4".
4692 (Redefined M4 Macros): Mention that Posix
4693 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4694 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4697 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4699 * bin/autom4te.in (handle_output): Do not forbid the empty
4701 * tests/tools.at (autoconf: the empty token): New test.
4703 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4705 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4706 calls, so that we do not care whether they are LIFO or FIFO;
4707 in the m4_wrap, do not check which diversion is the topmost
4708 one, just check that the stack is balanced at the end.
4709 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4710 base diversion forever--pop the previous diversion before
4711 opening the new one; consequently, remove the m4_wrap call.
4712 * lib/autotest/general.m4 (AT_INIT): Likewise.
4713 * tests/m4sugar.at: Do not use
4714 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4717 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4719 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4720 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4721 Rework example of m4wrap token-pasting trouble so that it doesn't
4722 care whether it's LIFO or FIFO.
4723 Fix some "contrary to"s that are awkward in English.
4725 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4727 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4728 to `yes' instead of `int$1_t' if the type is found, for more
4729 consistent configure output (where $1 is the number of bits).
4730 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4731 Suggested by Bruno Haible.
4733 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4734 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4735 with system headers. Report by Bruno Haible.
4737 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4739 * config/config.guess, config/config.sub: Sync from upstream.
4741 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4742 in order to avoid picking up an older installed frozen m4sh.m4f.
4743 Besides an outdated shell startup, this could have been created
4744 by an earlier M4 version with incompatible frozen file format.
4746 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4748 * README: Recommend m4 1.4.4 instead of 1.4.3..
4749 * doc/autoconf.texi: Likewise.
4750 (Special Chars in Names): Say that $(.FOO) is portable, as
4751 suggested by Stepan Kasal.
4752 (Installation Directory Variables, Build Directories):
4753 (Automatic Remaking, Subdirectories, Fortran Compiler):
4754 (Making testsuite Scripts, Defining Directories):
4755 Quote variable usages better.
4756 (Making testsuite Scripts): Add clean-local rule to makefile
4757 snippet, by Eric Blake.
4758 (Installation Directory Variables): Fix table item font.
4759 Reword slightly to clarify. Generalize advice about
4760 not using special characters to include all file-related
4761 vars, not just VPATH.
4762 (Special Chars in Variables): Warn about special characters in
4764 (Assignments): Clarify default-value example as suggested by
4766 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4767 (Special Shell Variables): Note leading ./ or ../, as suggested
4769 (Limitations of Builtins): Under cd, warn about CDPATH.
4770 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4773 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4775 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4776 `@var', for texi2html.
4777 (Systemology): Some more word wrapping, for DVI output.
4778 (autom4te Invocation): The short option for `--melt' is `-M',
4781 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4783 * doc/autoconf.texi: More formatting and English tweaks,
4784 many suggested by Ralf Wildenhues.
4785 Reword to avoid "@code{...}'s" and the like, since it's ugly
4786 with Emacs info mode. discontents -> woes.
4787 Put a few "will"s back. time stamp -> timestamp.
4788 side-effect -> side effect.
4790 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4792 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4793 Warn about $@ not persisting. Problem reported by Julien Danjou in
4794 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4795 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4796 Mention other special chars, too.
4798 2006-06-14 Eric Blake <ebb9@byu.net>
4800 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4802 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4804 * doc/autoconf.texi: Some systematic minor improvements, as
4805 follows. Use "makefile" when talking about makefiles
4806 generally (which might be named "makefile" or "Makefile" or even
4807 "foo.mk"), "Makefile" when talking about a specific makefile
4808 called "Makefile". This unclutters the text from weird quotes
4809 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4810 values" rather than "@var{foo}s" and similar constructs containing
4811 "}s". Use "Make rules" rather than "Makefile rules". Minor
4812 English-language improvements. Change the prefix "sub-" to "sub"
4814 Put blank lines around examples more consistently.
4815 Avoid "rather" and "very" as intensifiers.
4816 Avoid "will" as an auxiliary.
4817 (Limitations of Make): Split this node into....
4818 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4819 (Leading _ in Macro Names, Backslash-Newline-Newline):
4820 (Backslash-Newline Comments, Long Lines in Makefiles):
4821 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4822 (obj/ and Make, make -k Status, VPATH and Make):
4823 (VPATH and Double-colon, $< in Explicit Rules):
4824 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4825 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4826 New nodes, resulting from splitup of Limitations of Make.
4827 All cross-references changed. Raise the top node from
4828 a section to a chapter, and all subnodes accordingly.
4829 Redo the introductory wording to match the new organization.
4830 (Installation Directory Variables): Use an example that is
4831 closer to what Autoconf actually does. Mention that VPATH's
4832 value should not contain metacharacters or white space.
4833 (Fortran Compiler): Fix a VPATH bug in an example.
4834 (Leading _ in Macro Names): Mention that this problem is no longer
4835 of practical concern.
4836 (VPATH and Make): Reword the advice to make it clearer
4837 that Autoconf and Automake support VPATH in non-GNU make, but
4838 many packages have bugs in this area.
4839 ($< in Explicit Rules): Refer to Build Directories rather
4840 than using a (non-VPATH-safe) example.
4841 (Automatic Rule Rewriting): Mention the sort of disaster that
4842 can ensue with Solaris-style rule rewriting with VPATH.
4844 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4846 * doc/install.texi (Compilers and Options): Weaken the
4847 suggestion to use GNU make for VPATH builds.
4849 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4850 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4852 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4853 in regular expression.
4855 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4857 * doc/autoconf.texi (Installation Directory Variables):
4858 Drop extra @samp from `@table @samp' item.
4859 (Limitations of Usual Tools): Comment fix.
4860 Do not nest @samp just to point to other table items.
4861 (Writing testsuite.at) <AT_CHECK>: The second argument to
4862 `@dvar' is already @samp'ed.
4863 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4864 do not use @var in the second argument.
4866 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4868 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for

4874 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4875 `unused variable' compiler warning, for `-Wall -Werror'.
4876 Reported by Jaap Haitsma in
4877 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.

4881 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4882 case the compiler dumps core. Problem reported for
4883 OpenServer 5.0.7 by Tim Rice in
4884 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

4888 2006-06-06 Tim Rice <tim@multitalents.net>.
4890 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4891 "ERROR" only shows up in "make check" output if there is an

4915 * config/texinfo.tex: Sync from upstream.
4917 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4918 seen, invoke libtoolize with `--ltdl' argument.
4919 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4921 Suggested by Eric Blake.
4923 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4925 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4926 reported by Ralf Wildenhues.

4933 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4935 * doc/autoconf.texi: Modernize some of the references to Solaris.
4937 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4939 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4940 message issued by AC_REQUIRE.
4941 * tests/m4sugar.at: Check m4_require's error message.
4942 * tests/base.at: Check AC_REQUIRE's error message.
4943 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4945 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4947 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4948 `expout' as the last parameter.
4949 * tests/tools.at: Adapt to the above change.
4951 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4953 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4954 information about race-free implementations of mkdir.

4963 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4965 * NEWS: GNU make now recommended for VPATH builds.
4966 Mention that some macros are now documented to be obsolescent.
4967 * doc/autoconf.texi:
4968 Prefer "current" to "modern" to describe
4969 currently-used (albeit perhaps old-fashioned) hosts.
4970 Mention which ancient features no longer need to be worried about.
4971 setgid -> set-group-ID
4972 setuid -> set-user-ID (these are the Posix terms)
4973 Fix some misuses of "only".
4974 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4975 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4976 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

4984 (Installation Directory Variables): shall -> should
4985 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4986 Mention that it's now safe to use 3 and 4.
4987 (Limitations of Usual Tools): cp -r is now specified by Posix.
4988 Omit longwinded and obsolescent discussion of cp -f.
4989 Modernize discussion of expr, ls.
4990 (Limitations of Make): Modernize discussion of VPATH builds.
4991 Mention $? as a workaround in some cases.
4992 * doc/install.texi (Basic Installation):
4993 Mention "./configure; make; make install" first. Be more
4994 specific about why this file is generic. Remove unnecessary
4995 parens. Remove misleading "only". Remove obsolete advice
4996 about csh. Don't say "configure" takes awhile; say it
4997 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4998 and CC=c99 rather than CC=c89, as these are blessed by current
4999 Posix. Recommend GNU make if doing a VPATH build.
5001 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5003 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5004 examples involving shell prompts.
5006 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5007 and Paul Eggert <eggert@cs.ucla.edu>
5009 * doc/autoconf.texi (Here-Documents): Add details about the
5010 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5011 use "here-documents" instead of "here documents".
5013 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5015 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

5019 * doc/autoconf.texi (File System Conventions): Warn about ":"
5020 anywhere in directory names.
5022 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5024 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5025 about quoting the case statement, just in case.
5026 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5027 was fixed in ksh93g; reported by Ralf Wildenhues.
5029 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5031 * doc/autoconf.texi (System Services): Do not document

5041 argument with leading hyphen. Problem reported by Paul Eggert.
5043 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5045 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5046 about quoting ac_try: quote all of it, if any of it seems suspicious.
5047 This means we don't have to worry about ${ or sed any more.
5048 Also, double-quote the case statement, to work around misuses via
5049 underquoting as reported by Ralf Wildenhues in
5050 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5051 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5052 undocumented and dangerous macro.

5064 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5065 since evidently some packages rely on the old, broken behavior.
5066 Problem reported by Ralf Wildenhues in
5067 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5068 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5069 pre-2006-05-26 definitions, but leave in the comments that
5070 these macros are dangerous and should not be used.
5071 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5072 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5073 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5074 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5075 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5077 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5079 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5080 the use of 'tr', since this is our only use of 'tr'.
5082 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5083 and Paul Eggert <eggert@cs.ucla.edu>
5085 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5086 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5088 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5091 the output file in the `${datarootdir}' test.
5093 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5094 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5096 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5097 mention of `datarootdir' in the input file(s), but literal
5098 `${datarootdir}' in the output file, and we haven't warned yet,
5099 then warn as well: the user may have (erroneously) used
5100 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5101 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5102 * tests/torture.at (datarootdir workaround): Extend this test.
5105 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5106 and Paul Eggert <eggert@cs.ucla.edu>
5108 * doc/autoconf.texi (autoheader Invocation): The first argument to
5109 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5110 alternatives and clear up the language a bit.
5112 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5114 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5115 ac_config_guess, ac_config_sub, ac_configure.
5116 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5117 Fix typo that prevented an unnecessary space from being removed.
5118 Problems reported by Ralf Wildenhues in:
5119 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5121 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5123 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5124 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5125 Don't use the term "thread-safe" to talk about mkdir race
5126 conditions, since the problem is more a process than a thread
5127 issue. Problem reported by Stepan Kasal in:
5128 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5129 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5130 the test for 'install' more closely. Look at MKDIR_P first.
5131 Look in the PATH, and at /opt/sfw/bin.
5132 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5133 Don't bother to try mkdir -p, since we already check mkdir --version;
5134 just look at the version number. (There's no easy way to check
5135 for race-free implementations.)
5136 * tests/tools.at (autoconf: subdirectories): Adjust to above
5137 changes, since MKDIR_P now might end in "/mkdir -p".
5139 * doc/autoconf.texi (autoheader Invocation): Mention that the
5140 first arg of AC_DEFINE_UNQUOTED must be a literal.
5141 Problem reported by Ben Pfaff in
5142 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5144 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5145 * doc/autoconf.texi (Special Chars in Variables): New section.
5146 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5147 (Installation Directory Variables): Quote $(datadir) better.
5148 (Limitations of Builtins): Describe some of eval's trickiness.
5150 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5151 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5152 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5153 in front of every arg, not just trailing args. Quote apostrophes.
5154 (_AC_EVAL_ECHO): New macro.
5155 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5156 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5158 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5159 exposed by quoting of eval argument. Put the command on line line
5161 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5162 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5163 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5164 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5165 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5166 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5167 Use eval more safely.
5168 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5169 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5171 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5172 lines, exposed by quoting of eval argument.
5174 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5175 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5177 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5178 initialization of `ac_cv_exeext', do not override it if it was
5179 already set, unless it was set to `no', for compatibility with
5180 Autoconf-2.13, and comment this.
5181 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5182 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5183 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5184 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5185 Document that this test may be overridden by setting
5188 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5190 Revert these two patches:
5192 2006-04-06 Eric Blake <ebb9@byu.net>
5193 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5194 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5197 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5198 Clean up _AC_COMPILER_EXEEXT* macros.
5199 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5200 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5201 ac_file to the name of the default output file and call
5202 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5203 initial `rm' of the candidate files...
5204 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5205 the same list in subsequent `rm' calls, and for the temporary
5206 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5207 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5208 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5209 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5210 no longer needed) by libtool. Make it a cache check.
5211 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5212 copied here by mistake.
5213 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5214 _AC_COMPILER_EXEEXT.
5215 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5216 _AC_COMPILER_OBJEXT directly.
5217 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5219 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5221 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5222 Fix description of how the buggy `sed' works.
5224 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5228 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5229 ENOLCK. Only mention `make -j' when applicable. Only raise
5230 fatal errors when `make -j' is involved. Improve error message.
5232 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5234 * doc/autoconf.texi (Here-Documents): We now know more about
5235 the variable expansion in here documents bug.
5236 Thanks to Tim Rice and Stepan Kasal.
5238 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5239 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5241 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5243 * tests/autotest.at (Multiline command from M4 expansion):
5244 No failure to be expected if the shell quotes newlines in
5245 commands in the `set -x' output. Report by Tim Rice.
5248 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5250 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5251 expansion in the here-documents used by config.status, as that
5252 runs afoul of the Korn shell version M-12/28/93d bug described in
5253 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5254 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5255 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5257 2006-05-23 Jim Meyering <jim@meyering.net>
5259 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5260 Fix typo introduced with 2006-04-02 change. It reversed the sense
5263 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5265 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5266 ac_dB slightly, to save bytes in the script.
5267 Max out at 50 lines, rather than 96; this is more likely
5268 (though not guaranteed) to avoid obscure 'sed' failures.
5270 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5272 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5273 `tr -d -' as bad option argument. Work around this by deleting
5274 an unrelated character.
5275 Report by Tim Rice <tim@multitalents.net>.
5277 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5278 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5279 Stepan Kasal <kasal@ucw.cz>
5281 * doc/autoconf.texi (Particular Programs): Do not promise that
5282 we always prefer the GNU version of the program, and that we
5283 search according to PATH; both rules can have exceptions.
5284 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5285 AC_PROG_SED. Move descriptions of limitations
5286 to the Limitations of Usual Tools section.
5287 (Limitations of Usual Tools) <sed>: Mention script length
5288 limitations with Solaris /usr/ucb/sed.
5289 <grep>: Fix wording for empty alternative. Mention that -c and
5290 -l should not be combined, and that -E and -F should not be
5293 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5294 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5296 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5297 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5299 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5301 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5302 AC_DEFINE is now passed to m4_pattern_allow.
5303 * NEWS: Mention that; likewise for AC_SUBST.
5304 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5305 the parameter to m4_pattern_allow.
5306 * tests/tools.at: Add a check for that.
5308 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5310 * lib/autoconf/status.m4: Fix typos.
5312 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5314 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5315 only the files that this macro generates.

5319 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5320 the HP-UX sed limitation of 99 commands, labels do not count.
5321 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5323 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5325 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5327 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5328 Import the following fix from coreutils:
5330 2006-01-13 Jim Meyering <jim@meyering.net>
5332 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5333 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5334 not double-quote uses of that variable, to accommodate the rare
5335 case in which getmntent is available in none of the libraries
5336 checked. This happens at least on FreeBSD 5.0.
5338 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5340 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5341 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5342 some other programs unwisely rely on these undocumented vars.
5343 But put in warning comments about them.
5344 Problem reported by Ralf Wildenhues in
5345 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5346 * NEWS: Document that these variables are intended to go away.
5348 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5350 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5351 and set the language to C++ (analogous to the equivalent Fortran
5354 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5355 * doc/autoconf.texi (C++ Compiler): Document it.
5356 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5359 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5361 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5362 that caused config.status to generate 100-command sed scripts; the
5363 portable limit is 99.
5365 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5367 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5368 variable `ac_d' instead of `d' to avoid infringing namespace.
5369 Report by Ralf Menzel.
5371 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5374 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5375 * tests/tools.at (autoconf: subdirectories): New test, taken from
5376 the corresponding problem report by Ralf Wildenhues in:
5377 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5379 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5380 Quote some uses of shell variables if they might suffer unexpected
5381 globbing. This doesn't fix all instances of quoting problems that
5382 I found, just the easy ones that look safe.
5383 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5384 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5385 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5386 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5387 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

5394 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5396 * bin/autoreconf.in ($help): Reword according to the manual.
5397 Suggested by Olly Betts.
5399 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5400 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5402 * bin/autoreconf.in: Pass the directory argument to
5403 `require_configure_ac'. Fix comment.
5404 * tests/torture.at (Configuring subdirectories): Expose this.
5405 Reported by Olly Betts.
5407 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5409 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5410 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5411 Automake as follows:
5413 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5414 `$configure_in' instead of `configure.in', to preserve
5415 directory component.
5417 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5419 * config/config.guess, config/config.sub, config/texinfo.tex,
5420 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5422 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5424 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5425 test for C99 conformance; (bool) 0.5 is an integer constant
5426 expression, but (bool) -0.5 is not. Problem reported by Fedor
5427 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5429 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5431 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5432 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5433 Warn about obsolete install-sh files. Remove stray sentence
5434 fragment and fix cross reference.
5435 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5436 install -d; this undoes the 2006-05-10 change.
5437 (MKDIR_P): Mark with AN_MAKEVAR.
5438 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5439 that we don't require $INSTALL to be thread-safe. Move comments
5440 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5441 of AC_PROG_INSTALL. Output a message saying that we're checking
5442 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5443 MKDIR_P instead of AC_SUBST.
5444 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5445 Special magic for MKDIR_P, too.
5446 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5448 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5450 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5452 Sync from Automake, as follows:
5454 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5455 * config/install-sh: Initialize IFS, so field splitting isn't
5457 * config/mkinstalldirs: Likewise.
5458 * config/missing: Remove superfluous quotes. Replace all uses of
5459 `[' by `test', for consistency, and for..
5460 * config/missing (sed_minuso, sed_output): New variables.
5461 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5462 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5463 Fixes `missing' to detect `--output' for help2man. Fixes
5464 PR automake/483. Report by Dennis J. Linse.
5465 (autom4te): Document in `missing --help'.
5467 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5469 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5470 * config/install-sh: Don't use 'path' to talk about file names,
5471 as per GNU coding standards. Close a race condition reported by Ralf
5472 Wildenhues and Stepan Kasal. There is still a race condition
5473 on hosts that predate Posix 1003.1-1992, but we can't help this.
5474 Don't mishandle weird characters like space on pre-Posix hosts.
5475 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5476 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5477 AC_PROG_MKDIR_P from AS_MKDIR_P.
5478 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5479 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5480 earlier editions are not (including Automake 1.8.3).
5481 Do not suggest mkinstalldirs for thread-safety.
5482 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5483 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5484 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5485 presence of special characters and race conditions.
5486 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5487 in Autoconf's name space.
5489 2006-05-10 Bruno Haible <bruno@clisp.org>
5490 and Paul Eggert <eggert@cs.ucla.edu>
5492 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5493 from Automake with minor changes.
5494 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5496 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5498 * config/install-sh: Update to Automake CVS version, as follows:
5499 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5500 * lib/install-sh: Simplify the expr implementation of dirname.
5501 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5502 * lib/install-sh: Handle --, and diagnose unknown options.
5504 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5506 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5507 `./autom4te' to create `./testsuite', since the `all' target
5508 will ensure its presence, but `installcheck' should not create
5509 the uninstalled wrappers.
5511 * tests/torture.at (Unusual Automake input files): Skip if we
5512 detect automake < 1.8.
5514 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5516 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5517 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5518 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5521 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5523 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5524 munge (multiple) white space and other oddities.
5525 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5526 single quotes in variable assignment.
5527 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5528 and similar failures by adding multiple spaces, tabs, and other
5530 Report and different test suggested by Francesco Romani
5531 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5533 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5534 single quotes, we only need to search for single quotes; this
5535 both simplifies the search pattern, and makes us less
5536 susceptible to `echo' variations for arguments not containing
5538 (_AC_ARG_VAR_VALIDATE): Likewise.
5540 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5542 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5543 `$*' and IFS concatenation issue with traditional shells and
5544 bash-2.04. Report by Seanster@Seanster.com.
5546 2006-05-03 Bruno Haible <bruno@clisp.org>
5548 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5549 precisely which Mac OS X versions have the od problem.
5551 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5553 * doc/autoconf.texi: Use @option systematically.
5555 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5556 and Bruno Haible <bruno@clisp.org>
5558 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5560 (Integer Overflow): Mention the special case of integer division
5563 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5565 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5566 traditional shells like the Solaris one that do not use the
5567 first IFS character for assembling `$*'.
5568 Prompted by a related report from autoconf_bug@nro.ca.
5570 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5571 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5573 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5574 Mention more problems with the -e option.
5576 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5579 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5581 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5582 in URLs to improve DVI formatted output (requires texinfo 4.6).
5583 (System Services, Systemology, Shellology): Likewise.
5584 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5587 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5589 (Runtime): Fix macro argument names to match description:
5590 `action-if-found' -> `action-if-true' and similarly.
5591 (Obsolete Macros): Likewise.
5592 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5593 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5594 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5596 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5598 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5601 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5604 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5606 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5607 /bin/sh set unsorted output.
5608 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

5616 (Writing Test Programs): Fix some langauge. Recommend exiting
5617 with status 1, not merely nonzero. Clarify exit declaration.
5618 (Run Time): Move C exit status stuff to new Exiting Portably section.

5626 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5628 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5629 since as_me isn't set yet.
5631 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5633 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5634 a few minor bugs in this area.
5636 * doc/autoconf.texi (Programming in M4sh): Comment out the
5637 documentation of AS_BASENAME, for now.
5638 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5639 (Limitations of Builtins) <basename>: Do not refer to
5641 * bin/autoconf.as (me): Don't use AS_BASENAME.
5642 (dir): Remove the unused variable.
5643 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5644 AS_DETECT_REQUIRED. All uses changed.
5645 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.

5657 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5659 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5660 of "run time" and "run-time" changed to "runtime", for consistency.

5663 * lib/autoconf/general.m4: Likewise.
5664 * lib/autoconf/headers.m4: Likewise.
5666 * doc/autoconf.texi (Run Time): Document the exit status situation
5667 with more accuracy and detail.
5669 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5671 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5672 Archive is not officially `GNU' any more. Update URL.
5673 (Defining Directories): Likewise
5674 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5676 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5678 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5679 newline from the `trap' code to finish `config.log'; the NetBSD
5680 /bin/sh resets the exit status after an empty command, as
5681 documented in doc/autoconf.texi.
5682 Reported by Dalibor Topic <robilad@kaffe.org>.
5684 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5686 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5687 Suggested by Bruno Haible.
5689 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5691 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5692 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5693 Instead, just list the shells that we know work.
5694 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5695 changed. Be more cautious about the _cv_ variable.
5696 * tests/tools.at (Syntax of the shell scripts): Check the
5697 _cv_ variable once, at first, to avoid an internal autoconf error
5698 when sh -n does not work.
5700 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5702 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5704 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5706 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5707 use ">&-" since we're only 99.999% sure that this is portable,
5708 and since the MinGW bug is fixed in a different way.
5709 * lib/autotest/general.m4 (AT_INIT): Likewise.
5711 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5713 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5714 before opening config.log, to avoid hitting a bug on MinGW.
5716 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5718 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5719 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5720 This works around a MinGW bug reported by Eric Paire.
5721 Make sure that all writes to the log file append to it,
5722 rather than possibly losing data.
5723 * lib/autotest/general.m4 (AT_INIT): Likewise.
5725 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5727 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5730 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5734 * configure.ac (AC_INIT): Bump to 2.59d.
5736 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5740 * Makefile.maint (news-date-check): Do not require a leading `*'
5741 before the release date in NEWS.
5743 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5744 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5746 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5747 the instantiated file do not contain the string 'datarootdir'
5748 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5749 @mandir@, replace the reference '${datarootdir}' by the value.
5750 * tests/torture.at (datarootdir workaround): New test.
5751 * NEWS: Advertise this temporary fixup.
5752 Based on a patch by Bruno Haible, reported and analyzed by
5753 Paul Eggert and Noah Misch.
5755 2006-04-12 Eric Blake <ebb9@byu.net>
5757 * tests/autotest.at (Debugging a failed test): Fix comment.
5759 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5761 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5762 all the changes since 2006-04-07.
5764 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5766 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5767 succeeded, but `ln -s file dir' failed, take care to remove the
5768 leftover target before the next test, to prevent its spurious
5769 failure; also make sure `ln file dir' works before selecting it.
5770 Thanks to Keith Marshall for pointing this out.
5773 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5774 assignments in `at_debug_args', so that we put them correctly
5775 in the `run' script.
5776 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5777 Reported by Eric Blake.
5779 2006-04-11 Eric Blake <ebb9@byu.net>
5781 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5782 top-level tests after micro-suite has been run. Used in...
5783 (Debugging a successful test, Debugging script and environment),
5784 (Debugging a failed test): ...these new tests. The first of these
5786 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5787 macro, split out from...
5788 (AT_INIT): ...here, so that using -d also generates a run script.
5789 Document that -d inhibits top-level logging.
5790 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5791 inhibits top-level logging; debug scripts are created.
5793 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5795 * tests/autotest.at (Empty test, Empty check): New test to check it.
5797 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5800 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5802 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5803 the files if a problem appears. Make the empty *.at files
5804 read-only, too. Proposed by Ralf Wildenhues.
5806 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5808 * config/Makefile.am: Add comment to force updated Makefile.in.
5810 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5811 space only patch to this file, this patch causes the Makefile.in
5812 files that include freeze.mk to be updated, and thus have a
5813 newer time stamp again, which in turn makes a pristine CVS
5814 checkout have correct time stamps.
5816 * Makefile.maint (cvs-sv): New macro, to be used..
5817 (config.guess-url_prefix, config.sub-url_prefix)
5818 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5819 point to CVS text checkout of Gnulib files.
5820 (copyright-check): Bump current year.
5821 (announcement): Do not hard-wire `./announce-gen'.
5822 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5824 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5826 (wget_files): Update config.guess, config.sub, texinfo.tex by
5827 `wget-update', now that their URLs work again.
5829 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5831 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5832 Problem noted by Paul D. Smith.
5834 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5836 * doc/autoconf.texi: Remove unused words from word list.
5837 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5838 .x-sc_trailing_space: New files.
5840 * doc/standards.texi: Sync from gnulib.
5842 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5843 `LIBOBJDIR' as experimental.
5845 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5846 with a target directory; it's internally implemented as `cp'
5847 anyway, but since Autoconf advertises the possibility to use
5848 a target directory when LN_S is `ln -s', we need to find out.
5849 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5850 analyzed by Keith Marshall <keith.marshall@total.com>.
5854 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5856 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5857 confdefs.h as-is. In general, if it has backslash-newline or the
5858 like, then it doesn't work either to sort or to remove empty
5861 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5863 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5865 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5867 * lib/autom4te.in (Automake-preselections): Preselect
5870 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5872 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5873 apostrophe within a single-quoted string, as this is the usual
5874 tradition and is easier to read than '"'"'. Don't rely on the
5875 shell treating "$/" like '$/'. Use a more-consistent indenting
5878 2006-04-09 Eric Blake <ebb9@byu.net>
5880 * tests/autotest.at (Backquote command substitution),
5881 (Multiline backquote command substitution): Remove mistaken
5882 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5884 (Parenthetical command substitution, Multiline parenthetical
5885 command substitution): here.
5887 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

5920 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5921 (C Compiler): Move AC_C_LONG_DOUBLE to ...

5962 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5964 Revert the patch from 2006-04-01 and only improve
5965 _AS_DETECT_BETTER_SHELL:
5967 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5968 skip nonexistent directories.
5969 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5970 only shell candidates which exist.
5971 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5972 * lib/autotest/general.m4 (AT_INIT): No need to give three
5973 parameters to _AS_PATH_WALK.
5975 2006-04-07 Stepan Kasal <kasal@ucw.cz>,

5979 distinguish m4sugar macros.
5980 * tests/tools.at (autoupdating with aclocal and m4_include):
5981 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5982 test case by Noah Misch <noah@cs.caltech.edu>.
5984 2006-04-07 Stepan Kasal <kasal@ucw.cz>

5995 * doc/autoconf.texi (Programming in M4sh): Document that
5996 AS_MKDIR_P exits the script on failure.
5997 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5999 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 * config/elisp-comp, config/install-sh, config/mdate-sh,

6018 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6020 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6021 whether `set' quotes correctly: redirect stderr of the tested
6022 `set', and use a subshell, for Ultrix; use `sed' instead of
6023 `grep' for zsh `set' which may write binary output; match only
6024 at the beginning of a line, to avoid false positives.
6025 In order to avoid false positives by unrelated variables with
6026 multiline content, put the dump algorithm in a subshell and
6027 unset all variables containing newlines (except some which are
6028 special to the shell). Warn about cache variables that are

6075 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6076 (AC_CONFIG_COMMANDS): Do not do so here.
6077 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6078 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6079 2005-07-25 rewrite. Noticed by Noah Misch.
6081 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6082 _AC_PRESERVE_HELP_ORDER, ...
6083 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6085 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

6088 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6089 for --help from Cygnus `configure.'
6091 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6106 * doc/autoconf.texi (Help Formatting): New node.
6107 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6109 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6138 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6139 Use simplified args that Eric Blake originally suggested.
6141 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6143 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6144 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6145 Use 'comm' rather than N instances of grep; this also fixes a bug
6146 whereby substrings were incorrectly matched, causing us to not
6147 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6148 (exclude_list): Exclude empty macros.
6149 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

7022 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7023 by the function rather than ignoring it.
7024 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7025 comparing its address. Intel's interprocedural optimization was

7077 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7079 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7080 calls, so that the final expansion of this macro is shorter.
7081 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7082 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7083 the cleanup there. Use AS_VAR_* macros, to be more general.
7084 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.

7113 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7114 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

7135 Update limitations about when to call AC_CONFIG_HEADERS.
7136 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7137 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7138 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7139 ``Configuration Actions''; fix their index entries.
7141 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7142 options correctly. Process N-M as M-N if M is smaller than N.
7143 Process ranges correctly so that N-N will run only N.
7144 Sort and uniquify the tests that will be run. If there is more
7145 than one test, reinsert the banners for the tests.

7151 before passing the macro name to AH_TEMPLATE.
7153 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7154 now opens log after option processing; in particular, --version
7155 and --help do not touch config.log.

7174 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7176 When building in place, set srcdir="."; suggested by Tim Van Holder.
7178 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize

7181 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7182 does not mean "no --srcdir option".
7184 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7186 * tests/autoscan.at (autoscan): New file.
7187 * tests/suite.at: Use it.
7188 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7189 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7191 * tests/autotest.at (Keywords): Test keywords combinations.
7193 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7195 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7196 add "2>&1"; gzip 1.2.4 prints help on stderr.
7198 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7200 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7201 was pushdef'ed twice while popped only once. Push it only once.
7202 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7204 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7206 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7207 prefixed by mere "===", not "configure: === ".
7209 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7211 * Makefile.maint: Update from Bison.
7213 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7214 "<tab>" in comment, so that the point is understandable.
7216 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7218 Rewrite substantial part of lib/autoconf/status.m4.
7219 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7220 and CONFIG_COMMANDS are not processed in four separate loops.
7221 Instead, there is one main loop. This alows that the common code
7222 is expanded only once, thus config.status (and configure) is smaller.
7224 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7225 the AC_LIST_FILES and cousins macros are no longer used.
7227 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7228 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7229 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7230 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7231 contain the initialization, nor the for loop, nor the associated
7232 commands; all these go to ...
7233 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7234 _AC_OUTPUT_CONFIG_STATUS.
7235 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7236 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7237 (_AC_OUTPUT_FILE): The creation of the sed script ...
7238 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7239 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7240 _AC_OUTPUT_MAIN_LOOP.
7241 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7242 _AC_CONFIG_COMMANDS): Use ...
7243 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7244 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7245 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7246 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7247 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7248 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7250 (_AC_CONFIG_UNIQUE): Update.
7251 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7252 Replaced by this ...
7253 (_AC_LIST_TAGS): ... new common macro.
7254 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7255 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7256 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7257 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7258 this didn't belong to the `config commands' section.
7259 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7260 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7261 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7262 to the `config commands' section either.
7263 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7264 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7266 ... and many changes to the comments nearby.
7268 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7269 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7270 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7271 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7272 (#define header templates): The comment at the top of the generated
7273 header now includes the name(s) of the source file(s).
7275 Several unrelated small changes:
7277 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7278 parameter to AC_DIAGNOSE.
7279 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7280 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7281 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7282 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7284 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7285 in AC_OUTPUT doesn't double-quote it either.
7286 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7289 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7291 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7292 versions of Portland Group compiler produce single- and double-quoted
7293 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7294 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7296 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7298 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7299 This is a corrected version of yesterday's patch.
7301 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7303 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

7307 ac_cv_build_alias to ac_build_alias.
7308 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7310 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7311 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7312 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7313 (AC_ARG_VAR): ... here.
7314 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7317 Keep a list of all precious variables and process them with one simple
7318 for loop, instead of expanding all commands, or, OTOH, complicated
7319 processing of output of "set".
7320 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7321 variable names in new macro...
7322 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7323 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7324 a loop to assign all ac_env_* and ac_cv_env_* variables.
7325 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7327 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7328 its value to shell variable ac_precious_vars and call
7329 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7330 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7331 _AC_ARG_VAR_VALIDATE.
7333 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

7351 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7352 They are generated by the Tru64 v5.1B shell.
7354 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7356 Fix my changes from 2005-07-01; reported by Noah Misch.

7361 Fix cases when the varsions of Autoconf and Autotest don't match.
7362 Reported by Noah Misch.

7364 at_top_builddir, for compatibility with older autotest.
7365 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7366 is not set, use at_top_builddir, for compatibility with older
7367 versions of autoconf.
7369 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7371 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7372 Problem reported by Patrick Welche.
7374 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7376 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7377 sed substitution command, so that we allow | in program prefixes
7378 and program suffixes. (& is a problem anyway; we're not fixing
7380 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7381 configure_input, top_builddir, srcdir, etc.
7382 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7383 PATH_SEPARATOR in AUTOTEST_PATH.
7385 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

7393 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7394 directories with weird names. Apparently some people like living
7395 on the edge. However, improve the test that "pwd" actually does
7396 report a name for the working directory.

7416 document to output the default config_* lists to config.status.
7417 Don't recognize option --file, if the functionality is not there.
7418 Likewise for --header; moreover, recognize --he and --h as shortcuts
7419 for --help in that case.
7421 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7422 matches the order of execution. No code changed.

7444 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7445 (AC_SUBST): Call it.
7446 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7447 the directory specific variables; but don't call it for configure_input.
7449 2005-06-28 Derek Price <derek@ximbiot.com>
7451 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7454 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7456 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7457 directory have inherent problems with special characters like spaces,
7458 due to limitations in Make syntax. Problem reported by Alexandre
7460 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7473 from Justace Clutter.
7474 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7475 variable into diagnostic. Make the diagnostic an error, not a warning,
7476 because we really don't support spaces and suchlike in dir names.
7477 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7478 Don't worry about backslashes in srcdir; it can't happen now.
7479 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7480 Simplify ac_optarg handling.

7503 2005-06-21 Stepan Kasal <kasal@ucw.cz>
7505 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7506 b, t, r, w commands require single space, while : cannot have any.
7507 (Special Shell Variables): Fix sed code this in the example.
7508 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7509 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7511 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

7522 * doc/autoconf.texi:
7523 Don't mention Solaris versions so much, if a
7524 problem is common to all extant versions of Solaris. Say "SunOS
7525 4" instead of "SunOS" for SunOS 4.
7526 (awk): Mention more of the limitations of traditional Awk.
7527 (cat): Don't talk about cat -v.
7529 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

7540 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7541 Use shell builtins rather than 'expr', to work around expr bug.
7543 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7545 * doc/autoconf.texi: "filesystem" -> "file system".
7546 "behaviour" -> "behavior".

7552 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7554 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7555 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7556 to update the man page. That way, we don't have to check in new
7557 man pages every month.
7559 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7560 quotes and backslashes. Patch from Derek Price.

7567 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7569 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7570 -u, since it outputs chatter if the input files are the same.
7571 Problem reported by Ralf Menzel.
7573 2005-06-08 Derek Price <derek@ximbiot.com>
7575 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7576 renaming them since they are about to be redefined anyhow.
7578 2005-06-08 Derek Price <derek@ximbiot.com>
7580 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7581 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7582 Move m4_undefine to alphabetical order.
7584 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7586 * README: Recommend GNU M4 1.4.3 or later.
7587 * doc/autoconf.texi (Introduction): Likewise.
7588 Reword to avoid some formatting glitches.
7589 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7590 Clarify explanation of HP compiler bug.
7591 Redo example output tp match current CVS snapshot.
7592 Use @example.org in email addresses when the examples
7593 might get inadvertently cut-and-pasted into user code.
7594 Remove example of autom4te usage that doesn't seem to work now.
7595 Use modern AC_INIT (except when the example is meant to be
7596 shown with Autoconf 2.13).
7597 Update ksh info for Solaris 9 and later.
7599 Modernize description of Automake versions a bit.
7600 Don't claim a future version of Autoconf is near.
7601 * doc/install.texi: Reword to avoid some formatting glitches.
7603 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7606 follows its own advice about quoting better.
7607 Reword to avoid some formatting glitches.
7608 * doc/installt.exi: Reword to avoid some formatting glitches.
7610 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7611 Tru64 ksh pattern matching bug. Reported against Libtool by
7612 Albert Chin <libtool@mlists.thewrittenword.com> and
7613 Nicolas Joly <njoly@pasteur.fr>.
7615 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7617 m4_cdr of one-member list was [[]] (one-member list containing an
7618 empty string) instead of [] (an empty list. Callers were skewed to
7619 match this misbehaviour. As a consequence of this:
7620 - m4_foreach([x], [], [foo]) expanded to `foo', while
7621 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7622 This bug has been fixed:
7624 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7625 expand to an empty string; print error msg if called without
7627 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7628 misbehaviour; handle [] and [[]] correctly.
7630 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7632 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7633 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7634 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7636 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7638 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7639 swallow records with more than 99 fields.
7640 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7641 parse the long line.
7643 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7645 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7646 swallow literals longer than 399. Reported by Ralf Wildenhues.
7647 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7648 to workaround this limitation.
7650 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7652 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7653 to gfortran, and make these the first two compiler names
7654 checked (following the general autoconf preference for gcc).
7656 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7658 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7659 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7660 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7662 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7664 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7665 expression of unbounded size when processing the --list
7666 option. This runs afoul of a limit of 399 bytes per regular
7667 expression on AIX. Problem reported by Ralf Wildenhues.
7669 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7671 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7672 * doc/autoconf.texi (Particular Headers): Reword example
7673 for multiline stdbool replacement.
7674 (Setting Output Variables): Reword text a bit. Don't
7675 give all the details about |#_!!_#|.
7676 Reword description of line replacement.
7678 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7681 now contain newlines, and substituted files must be referenced on
7682 a line alone; the sed scripts to substitute them are now very
7684 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7685 commands can be put in a sed script portably.
7686 * doc/autoconf.texi (Setting Output Variables): Document above
7687 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7688 use of multiline substitution.
7689 * tests/torture.at: No longer expect substitution of newline to fail.
7691 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7693 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
7694 From Ralf Menzel (trivial change).
7696 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7698 * tests/local.at: Don't attempt to check for negated character
7699 classes in shell scripts. The test was too brittle.
7701 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7703 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7704 * doc/autoconf.texi (Limitations of Builtins): Document this
7707 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7709 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7710 common code; used in many places in the tree.
7711 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7712 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7714 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7716 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7717 messages when ac_unique_file is not found.
7718 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7719 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7720 commands, for consistency with AC_MSG_ERROR and such.
7722 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7724 * bin/Makefile.am: Merge the two rules for creating scripts.
7726 2005-05-23 Stepan Kasal <kasal@ucw.cz>

7729 obsolete; it was never documented.
7730 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7732 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7734 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7735 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7736 (ac_top_builddir): ... this ...
7737 (ac_top_build_prefix): ... to this; the old name is also kept, for
7738 backward compatibility.
7739 (ac_top_builddir_sub): New variable, without the trailing slash,
7741 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7742 * doc/autoconf.texi (Configuration Actions): Rename
7743 ac_top_builddir to ac_top_build_prefix.
7744 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7745 at_top_builddir to at_top_build_prefix.
7746 * lib/autotest/general.m4 (AT_INIT): Likewise.
7748 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7750 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7753 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7755 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7756 argument to m4_foreach. I guess it was necessary in the past,
7757 but I think it's a no-op now.
7759 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7761 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7762 ``cat <<_ACEOF'' commands to one.
7763 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7764 * lib/autoconf/status.m4: On various places, use expr instead of
7766 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7767 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7768 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7770 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7771 the wrong patterns between ``case'' and ``esac.'' The previous
7772 code had false positives.
7774 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7776 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

7819 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7821 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7823 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7824 enough arguments, similarly as in m4_bpatsubsts.
7826 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7828 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7831 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7833 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7834 for absolute directory names in one loop.
7835 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7836 abbreviations of --version and --debug.
7838 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7840 * doc/autoconf.texi (Autoconf Language): Be more precise about
7841 quoting rules. Problems noted by Stepan Kasal.
7842 Also, throughout this document, be more careful about white space.
7843 "blank", "white space", and "space" all have different meanings
7844 and we should be careful to say what we mean.
7846 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7848 Fix C++ related problems reported by Werner Lemberg.
7849 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7850 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7851 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7852 avoid problems with C++ and throw.
7853 * tests/compile.at: .cpp, not .cc.
7855 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7857 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7859 * doc/autoconf.texi (Generic Functions): Typos.
7861 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7863 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7864 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7865 set by latest automake.
7867 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7869 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7870 outputs 0 on GNU/Linux these days.
7872 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7874 * doc/autoconf.texi (Autoconf Language): Add more description
7875 about quoting heuristics.
7876 (Limitations of Builtins): Describe "set -" problems.
7878 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7880 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7883 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7884 by AC_DEFINE; it was a mistake.
7885 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7887 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7889 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7891 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7893 * doc/autoconf.texi (External Software): Quadrigraphs are not
7894 processed correctly in AS_HELP_STRING; avoid this in the examples.
7895 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7896 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7897 comment and reduce m4_default([foo], []) to [foo].
7898 (m4_strip): Update the explanation.
7900 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7902 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7903 Remove core.conftest.* too; it's generated by Tru64 5.1.
7904 Problem reported by Jennis Pruett.
7905 * lib/autoconf/functions.m4
7906 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7907 Don't bother to remove core files; AC_RUN_IFELSE should do that
7910 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7912 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7914 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7916 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7917 Report from Horst Wente.
7919 2005-04-15 Stepan Kasal <kasal@ucw.cz>
7921 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
7924 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7926 * doc/autoconf.texi (External Software, Package Options): Add
7927 examples showing how to implement --with-* and --enable-* options.
7929 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7931 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7932 as well as configure.in. Problem reported by Gregorio Guidi.
7934 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7936 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7937 pattern for alloca snippet.
7939 2005-04-04 Stepan Kasal <kasal@ucw.cz>
7941 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

7949 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7950 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7952 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7954 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7955 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7956 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7957 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7958 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7960 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7962 * NEWS: The configure command now warns you if you attempt to use
7963 a directory whose name contains a special character like space,
7965 * doc/autoconf.texi (Installation Directory Variables): Allow
7966 "," in file names. Do not use \@; it's not a portable regexp.
7967 * bin/Makefile.am (edit): Likewise.
7968 * lib/Makefile.am (edit): Likewise.
7969 * tests/Makefile.am (edit): Likewise.
7970 * tests/semantics.at: Likewise.
7971 * tests/torture.at: Likewise.
7972 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7973 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7974 * doc/autoconf.texi (File System Conventions): Warn about
7975 unportable file names.
7976 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7978 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7979 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7980 ac_pwd, and quote srcdir.
7981 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7983 * doc/autoconf.texi: Fix some systematic formatting problems.
7984 ".)" needs a following @: if not at the end of a sentence, and
7985 similarly for "!)". "etc." should be preceded by a comma.
7986 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7988 2005-03-22 Bruno Haible <bruno@clisp.org>
7990 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7991 argument is often called 'build-aux'.
7993 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7995 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7996 macro AC_TRY_LINK is obsolete.
7997 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8000 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8002 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8003 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8004 from a Common Lisp's `cl'.
8005 (AC_PROG_CXX): Behave according to the documentation: don't
8006 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8007 make the variable CCC precious; use `cl.exe', not `cl'.
8009 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8010 Alexandre Duret-Lutz <adl@gnu.org>
8012 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8013 /dev/null, as "configure" shouldn't read stdin, and this insulates
8014 us from problems (e.g., when testing for "cl"). Also, do this
8015 redirection before invoking "hostname" or "uname", and keep the
8016 original input stream available via...
8017 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8018 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8019 bother with "</dev/null" since it's now done at the top of
8021 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8022 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8023 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8024 * doc/autoconf.texi (File Descriptor Macros): New section.
8025 (Printing Messages): Mention it.
8026 * tests/base.at (Input/Output): New test.
8028 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8030 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8031 newline if neither \c nor -n work, as that would output two
8032 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8034 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8036 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8037 This causes that any required macros inside will get before the if.
8038 * doc/autoconf.texi (autom4te.cache): A typo.
8040 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8042 Undo previous change, except keep the change to
8043 lib/autoconf/programs.m4 that replaced grep with shell
8044 pattern-matching. This is because net-snmp configure reads stdin.
8045 Reported by Noah Misch.
8047 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8049 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8050 from /dev/null, as "configure" shouldn't read stdin, and this
8051 insulates us from problems (e.g., when testing for "cl").
8052 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8053 before invoking "hostname" or "uname".
8054 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8055 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8056 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8057 "</dev/null" since it's now done at the top of 'configure'.
8058 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8059 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8060 Also, replace grep with shell pattern-matching, to save a process.
8062 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8064 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8065 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8066 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8069 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8071 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8072 grep -q isn't portable. Improve grep -s explanation.
8073 Problem reported by Dan Manthey.
8075 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8077 * doc/autoconf.texi (Special Shell Variables): Clarify
8078 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8080 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8082 * doc/autoconf.texi: Use @acronym for DJGPP.
8083 Fix some @code's that should have been @env's, and vice versa.
8084 Sort environment variable names.
8085 Mention that shells no longer inherit IFS.
8086 Don't recommend PATH_SEPARATOR=';' so strongly.
8087 Mention that $RANDOM might expand to the empty string.
8088 "symlink" and "soft link" -> "symbolic link".

8165 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8228 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8229 Update the long comment explaining it.
8231 m4_require no longer writes an ``is required by'' line to the
8232 execution stack. It contains only one bit of non-redundant
8233 information: that the macro was required, not called. And even
8234 this bit is useless in most situations: have you ever met a macro
8235 which both calls and requires the same macro?
8237 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8238 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8245 (_m4_require_call): Use it.
8246 * tests/m4sugar.at (m4_require): Expect output without the
8247 ``is required by'' messages.

8285 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8286 Warn about newline stripping in `` and $(). Update Solaris
8288 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8289 X insulates us from future changes to Posix.

8317 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8343 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8344 stored in _m4_divert_diversion or _m4_divert_dump.
8345 (m4_divert_pop): When the parameter is given, compare the symbolic
8346 name with the last diversion pushed on the stack. Previously, the
8347 current diversion was compared with the numeric value of the
8348 diversion given as the parameter.
8349 (m4_require): If the macro hasn't been expanded yet, call ...
8350 (_m4_require_call): this new macro.

8629 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8631 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
8632 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8633 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8634 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

8650 out the common code to ...
8651 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the

8653 with exactly one parameter.
8655 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8657 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8658 "char c = '\200';" rather than "char c = 0x80;" as the
8659 latter doesn't conform to the strict C standard due to
8660 overflow on signed char hosts.
8662 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8663 to -qlanglvl=ansi. We don't want to disable extensions.
8665 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8667 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

8715 * doc/autoconf.texi (Autoconf Language): Explain that
8716 ``descriptions'' may not be double quotes.
8717 (Quotation Rule Of Thumb): Likewise.

8719 simplify the examples and improve their quoting.
8721 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8723 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8724 the $1_found variable, don't test whether the file is executable;

8746 (Shellology, Special Shell Variables): Document that the Zsh
8747 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

8759 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8761 * doc/autoconf.texi (auindex): New macro.
8762 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8763 Problem reported by Stepan Kasal.
8765 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

8774 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8776 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8777 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8778 (trivial change). Problem and patch reported by Andrew Church in:
8779 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8781 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8783 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

8808 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8809 texinfo.tex for now (done by hand now).
8810 * Makefile.maint (wget_files, cvs_files):
8811 Remove ansi2knr.c; nobody uses it.
8812 (ansi2knr.c-url_prefix): Remove.
8813 (cvs-update): Fix test for failure. I don't know why it ever
8816 * doc/autoconf.texi: Update URLs, some of which went stale.
8817 Use @uref rather than @href.
8819 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8820 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8822 * config/config.guess, config/config.sub, config/elisp-comp,
8823 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8824 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8832 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8833 tests/tools.at, tests/torture.at:
8834 Use "file name" rather than "filename" or "path",
8835 to be consistent with the terminology of the GNU coding standards.
8837 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8839 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8840 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8841 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8842 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8844 More fixes to support spaces in the name of the build directory.
8845 This isn't a complete fix but it's an improvement.
8847 * bin/autoconf.as (autom4te_options): New var.
8848 Use it instead of appending to AUTOM4TE, so that we can allow
8849 spaces in the build directory's absolute name.
8850 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8851 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8852 AT_CHECK_NOESCAPE): Likewise.
8853 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

8864 * doc/autoconf.texi (Function Portability): Document isinf and
8865 and isnan. From a suggestion by Kevin Ryde.
8867 * lib/Autom4te/General.pm (END): Return correct exit status even
8868 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8870 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8872 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8873 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8874 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

8881 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8882 * lib/autom4te.in (Automake-preselections): Preselect
8883 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8885 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8887 * lib/autom4te.in (Automake-preselections): Preselect
8888 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8891 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8893 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8895 * doc/autoconf.texi (Shellology): Mention BIN_SH.

8898 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8900 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8901 with pdksh, too. Problem reported by Patrick Welche via
8903 * doc/autoconf.texi (Shellology): Note that set -o posix is
8904 useful for pkdsh, too.
8906 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8908 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8909 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8910 Don't fail if ENV or BASH_ENV is readonly.
8911 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8912 etc. are read only. Problem reported by Ludovic Courtes.
8914 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8916 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8917 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8920 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8922 * doc/autoconf.texi (File System Conventions): Warn about
8923 names like "aux". Problem reported by Eric Blake.
8925 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8926 by zero instead of array size, so that we can use any arithmetic
8927 constant expression (instead of requiring an integer constant
8928 expression). This allows us to test expressions like DBL_MAX <
8929 LDBL_MAX, which didn't conform to the C standard using the old
8931 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8932 now that we can do floating-point tests at compile time.
8934 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8936 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8937 and LDBL_EPSILON, as the resulting expression isn't an
8938 integer constant expression and violates the C standard.
8939 Problem reported by Nelson H. F. Beebe. Also, check
8940 for "L" suffix, and check that long double doesn't have
8941 worse range or precision than double, that mixed-mode
8942 arithmetic doesn't generate a diagnostic, that double
8943 constants fit in long double.
8945 2004-06-03 Kevin Ryde <user42@zip.com.au>
8947 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8948 malloc(0) and realloc(NULL,size).
8950 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8953 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8955 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8956 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8959 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8961 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8962 can be rewritten using if-then-else. Suggested by Bruno Haible.
8964 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8966 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8967 Problem reported by Stepan Kasal.
8969 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8971 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8972 change). Patch reported by Ralf Wildenhues in
8973 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8975 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8976 function F exists if the compiler and linker let you compile an
8977 expression like (F != 0). Recent versions of GCC optimize away
8978 the reference to F in that case, since every function address must
8979 be nonzero, so the link succeeds even if F does not exist.
8980 Problem reported by Manu in
8981 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8983 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8984 "Unix". Many uses changed.
8985 (Limitations of Builtins): Explain better why the ! command isn't
8988 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8990 * lib/autom4te.in (Automake-preselections): Preselect
8991 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8993 2004-05-19 Kevin Ryde <user42@zip.com.au>
8995 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8996 referencing AC_FUNC_STRERROR_R.
8998 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8999 note pessimistic assumption when cross compiling.
9001 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9003 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9004 (until 2004) invoked subcommands with sh -e, contra POSIX.
9005 Reported by Kevin Ryde.
9007 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9009 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9010 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9011 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9012 `test -f " /usr/bin/grep"', which _always_ failed.
9013 (AC_PROG_SED): Ditto bogus PATH fix.
9014 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9015 requires that grep correctly supports _multiple_ `-e' options, rather
9016 than stating only that grep should accept `-e'.

9020 Port to C99, which requires that 'exit' be declared.
9022 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9023 to ensure that stdlib.h is included.
9024 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9025 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9026 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9027 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9028 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9029 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9030 when using 'exit' in a test; C99 requires that 'exit' be declared.
9032 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9034 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9035 now prefers 'grep' implementations that accept -e.
9036 (Limitations of Usual Tools): Describe problems of traditional
9037 egrep and fgrep with long input lines, and of traditional grep
9039 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9040 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9041 All callers changed. Append /usr/xpg4/bin to the PATH, for
9043 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9044 the user with complaints about multiple -e options.
9045 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9046 Define it with AC_PROG_GREP.
9047 * configure.ac (AC_PROG_GREP): Add.
9048 * lib/freeze.mk (GREP): New macro.
9050 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9052 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9053 a possible candidate only after all others fail, rather than
9054 consulting it first. This improves backward compatibility by
9055 better reflecting the way shell selection occurred in previous
9056 versions of Autoconf, and should help to avoid triggering latent
9057 problems in other packages, such as the one in Automake where zsh
9058 is not handled robustly:
9059 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9060 Although it is not Autoconf's responsibility to work around
9061 problems in Automake, it nevertheless makes sense to avoid
9062 introducing unnecessary incompatibilites.
9064 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9065 Gary V. Vaughan <gary@gnu.org>
9067 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess

9069 ac_path_TOOL_found flag.
9070 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9071 nested we are in this macro. Break out of all 3 nested loops if
9072 ac_path_TOOL_found is set.
9074 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9076 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9077 of the _AS_PATH_WALK loop too if GNU flavor is found.
9079 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9081 * doc/autoconf.texi (Limitations of Make): Update documentation
9082 for `$<'. New entry `Long lines', based on a report from Simon
9083 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9084 paragraph about DJGPP, based on a mail from Richard Dawe.
9086 2004-04-20 Paul Eggert <eggert@twinsun.com>
9088 * tests/c.at (C keywords): Don't assume that GCC supports
9089 "restrict" and "inline", as sufficiently-old GCC versions do not
9090 (also, GCC configured to be in pedantic C89 mode does not).
9091 Problem reported by Sumit Pandya in:
9092 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9094 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9095 consider -g to work if it generates warnings when plain compiles
9096 don't. Problem reported by Braden McDaniel in:
9097 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9099 * doc/autoconf.texi (Slashes): New section, to document a problem
9100 reported by Jim Meyering in:
9101 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9103 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9104 linker output files before linking, to work around IRIX 6 linker bug.
9105 Problem reported by Rainer Orth in:
9106 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9108 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9110 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9111 best tool so far counter rely on the tool path variable name to
9112 avoid checks for one tool being affected by the results of running
9113 the length check on a previous tool.
9115 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9116 match expression argument, as different greps have different
9117 regular expression flavours.
9118 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9120 (AC_PROG_EGREP): Pass 'EGREP$'.
9121 (AC_PROG_GREP): Pass 'GREP$'.
9123 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9125 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9126 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

9130 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9131 Types, Specific Compiler Characteristics, System Services,
9132 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9133 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9134 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9135 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

9146 2004-03-28 Paul Eggert <eggert@twinsun.com>
9148 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9149 now defines HAVE_DECL_TZNAME if it is declared, when
9150 HAVE_STRUCT_TM_TM_ZONE is not defined.
9151 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9152 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9159 thanks to Paul Eggert.
9161 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9163 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9164 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9165 H. F. Beebe for the bug report.
9167 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9169 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9170 quoted -cmdline argument in Portland Group compiler (bug

9200 * tests/mktests.sh: Do not generate tests for the
9202 * NEWS: Document these changes.
9204 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9205 they make TeX hang up.

9215 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9216 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9219 2004-03-03 Paul Eggert <eggert@twinsun.com>
9221 * bin/Makefile.am (edit): Don't use $< in a context where
9222 POSIX doesn't require support for it. Use $@.in instead.
9223 Problem reported by Anthony N. Frasso in
9224 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9225 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

9229 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9230 from the next generation of Libtool.
9231 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9233 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9235 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9236 is not always thread-safe. Report from Nathanael Nerode.
9238 2004-02-18 Paul Eggert <eggert@twinsun.com>
9240 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9241 problem on QNX reported by Stephen Rasku in
9242 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9244 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9245 $(m4sh_m4f_dependencies); this removes a FIXME.
9246 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9247 (MAINTAINERCLEANFILES): Split into pieces,
9248 one per related section. Add $(srcdir)/wrapper.in.
9250 2004-02-09 Paul Eggert <eggert@twinsun.com>
9252 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9253 AC_SUBST provides no portable way to escape literal newlines.
9255 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9256 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9257 Darwin uses -lcrt2.o and there's little point to cataloging all
9258 the system variants. Partial fix reported by Andreas Waechter in:
9259 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9260 for bug reported by Nelson H. F. Beebe in:

9273 refer to the correct file.
9274 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9275 the behavior of the third argument.
9276 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9277 correctly the behavior of the third argument. Document
9278 what the three macros that AU_DEFUN defines do. Fix
9279 warning message when the third argument includes $0

9286 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9303 use AS_INIT_WITH_SHELL_FN.

9332 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
9334 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9335 2003 (except 1997) to the list of copyright years. This undoes
9336 the 2003-05-22 change, which removed the older years from the list.
9337 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

9343 grep or ggrep program in PATH that accepts as long lines as
9345 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
9347 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
9348 egrep and fgrep respectively if $GREP -E/-F don't work.
9349 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9350 _AC_PROG_GREP, and AC_PROG_SED.
9351 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9352 longest input length accepted by a command.

9381 2004-01-26 Paul Eggert <eggert@twinsun.com>
9383 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9384 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9385 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9386 not <inttypes.h>. Problem reported by Tim Mooney in
9387 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9388 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9391 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9392 otherwise "make check" fails because it forbids cmp (I guess
9393 because cmp treats files as binary on DOS-like systems).
9395 * tests/mktests.sh: Update copyright date to 2004, since some tests
9396 have changed in 2004.
9398 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9400 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9401 non-truncating sed or gsed program in PATH.
9402 * tests/acprograms.at: Add it.
9403 * doc/autoconf.texi (Particular Programs): Document it.
9406 2004-01-15 Paul Eggert <eggert@twinsun.com>
9408 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9409 -std1 disables some useful extensions on Tru64. Problem reported
9411 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9413 2004-01-14 Paul Eggert <eggert@twinsun.com>
9415 * doc/autoconf.texi (Programming in M4sh): Document that
9416 AS_MKDIR_P succeeds if the destination is a symbolic link
9417 to an existing directory.
9418 (Limitations of Usual Tools): Note that mkdir -p might not
9419 succeed on symlinks to directories.
9421 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9423 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9424 * bin/autoheader.in: Grammar fix in message.
9425 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

9433 2004-01-10 Jim Meyering <jim@meyering.net>
9435 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9437 2004-01-09 Paul Eggert <eggert@twinsun.com>
9439 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9440 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9441 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9442 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9443 AC_COMPILE_IFELSE, since we now assume our caller invokes
9444 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9445 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9446 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9447 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9449 2004-01-07 Paul Eggert <eggert@twinsun.com>
9451 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9452 `"'...'"`, as it's confusing (and I suspect it may not work on
9453 some platforms). The code was incorrect anyway, as it assumed
9454 that \$ evaluated to itself in that context. Reported by
9455 Alexandre Duret-Lutz.
9457 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9459 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9980 to find non installed files is turned off. This caused a failure
9981 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9982 as found in its environment (sent by tests/autoreconf): pointing
9983 to bin/autom4te that could not find its files.
9984 * tests/mktests.sh: Force the replacement of generated files, for
9985 the sake of "mv" program that are interactive when overwriting a
9987 * config/install-sh: Upgrade from CVS Automake.

10083 unchanged, and continues to support Fortran 77. New FC macros
10084 correspond to all the old F77 macros, with output variables FC,
10085 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10086 available dialect, but older dialects can be specified. There are
10087 new macros AC_FC_SRCEXT to set the source extension, and
10088 AC_FC_FREEFORM to accept free-form source files.

10214 2003-08-21 Akim Demaille <akim@epita.fr>
10216 First stab at preserving warnings between calls to autom4te,
10217 including when the cache is used.
10219 There are still several issues: (i) there are too many runs of m4
10220 (one for include, one for warnings, and some more), (ii) warnings
10221 spreading on several lines are not handled gracefully, (iii) the
10222 code meant to have the call stack display for errors does not work
10223 (its handling should move from m4 to autom4te).
10225 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10227 (@preselect): Add m4_warn.
10228 ($exit_status): Remove, use $exit_code.
10229 ($help): Use Autom4te::ChannelDefs::usage.
10230 (&handle_m4): No longer define the m4_warnings.
10231 At each run, extract and report the warnings.
10232 Always cache the result, including if the exit status is on
10233 failure, since if nothing changes, we should result in the same
10234 failure, hence we can use the cache.
10235 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10236 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10238 (m4_warn): Redefine as a do-nothing: it is its invocation that
10239 matters, as warnings are now reported via traces.
10240 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10241 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10242 the latter reveals calls to the former.
10246 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

10268 (&catfile): Remove.
10269 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10270 * bin/autoscan.in: Adjust.
10272 2003-08-20 Akim Demaille <akim@epita.fr>

10275 Reported by Alexandre Duret-Lutz.
10277 2003-08-20 Akim Demaille <akim@epita.fr>
10279 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10280 * bin/autom4te: Adjust.
10281 In particular, be Autoconf tools are really silent when properly
10282 working, bind the verbosity of the 'note' channel to $verbose.
10283 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10284 (&xsystem, &contents): Remove, since they are exported by...
10285 * lib/Autom4te/FileUtils.pm: this.

10288 * lib/Autom4te/FileUtils.pm: here.

10407 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10408 not all of them. This fixes 1. the fact that when testing
10409 Autoconf there are many many config.log, 2. the incorrect use of
10410 top_srcdir to find config.log.
10411 Don't mix the detailed output of failed test with the summary of
10412 failures. Rather, append detailed log afterwards.
10414 2003-06-23 Akim Demaille <akim@epita.fr>

10474 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10475 (AT_INIT): Support for expected failures.
10477 2003-06-02 Akim Demaille <akim@epita.fr>

10486 2003-05-28 Paul Eggert <eggert@twinsun.com>
10488 * NEWS, doc/autoconf.texi (Particular Functions),
10489 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10490 is the inverse of localtime.
10492 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10494 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10495 (handle_exec_errors): New function. Work around $! being
10496 altered by WEXITSTATUS.
10497 (xqx, xsystem): Use handle_exec_errors.
10499 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10501 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10502 Do not call `_exit()', simply modify `$?'.
10503 (xsystem): Reset $! before running system, and check it afterward.
10504 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10505 63 for version mismatches.
10507 2003-05-23 Akim Demaille <akim@epita.fr>
10509 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10510 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10511 the middle of a line).
10512 * lib/m4sugar/m4sugar.m4: Likewise.
10513 Remove useless spaces in comments.
10515 2003-05-23 Akim Demaille <akim@epita.fr>
10517 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10518 exit 63, so that we (or Automake's "missing") can tell the
10519 difference with a plain failure.
10520 * doc/autoconf.texi (Notices): Adjust.

10529 Paul Eggert <eggert@twinsun.com>
10531 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10532 Remove `#include <stdlib.h>' from the list; we should never
10533 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10534 resulting namespace pollution would cause other tests to fail.
10535 Configure scripts run with some older versions of g++ and HP's
10536 aCC would fail due to such an #include. Problems reported by
10537 Matthew Mueller in <http://bugs.debian.org/120704> and by
10539 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10540 In the test, use the test declaration before including <stdlib.h>,
10541 as that's closer to how it'll be used.
10543 2003-05-23 Akim Demaille <akim@epita.fr>
10545 * doc/autoconf.texi (Header Portability): ucred.h.
10548 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10550 Overhaul Autotest's logging: generate separate log files
10551 in testsuite.dir/NNN/testsuite.log, and append them to
10552 testsuite.log instead of re-running the test verbosely.
10554 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10555 file descriptor, write 0 to at_status_file instead of setting
10556 at_status=0, initialize some new variables (at_status_file,
10557 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10558 to rerun the tests, instead append the at_group_log to the
10559 at_suite_log when a test fails.
10560 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10561 with the AS_MESSAGE_LOG_FD redirected to stdout.
10562 (AT_CLEANUP): save the output status in $at_status_file
10563 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10564 its original place.
10565 (AT_CHECK): since tests are run with a redirected stdout,
10566 and used to be re-run in verbose mode, turn some $at_verbose
10567 into echo, and don't redirect the output of testing stdout
10570 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10571 the name of the debugging directory and information about
10574 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

10691 2003-05-06 Akim Demaille <akim@epita.fr>
10693 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10694 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10695 by aclocal.m4 is changed it might require the importing of another
10696 m4 extension file, i.e., aclocal must be run.
10698 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10699 (&parse_args): Use --force with aclocal if required and supported.

10713 2003-04-29 Derek Price <derek@ximbiot.com>
10715 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10716 seperator with m4_append_uniq(). It doesn't work.
10717 (AT_CLEANUP): Add `;' to end of at_help_all.
10718 (AT_INIT): Allow --keywords to be specified more than once. When
10719 grepping $at_help_all for keywords, use the field and keyword
10720 seperators to ensure a complete keyword match. Alter at_prev handling
10721 to support the new --keywords behavior.
10723 2003-04-27 Karl Berry <karl@freefriends.org>
10725 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10726 align better with others. I also made some of the individual
10727 entries on one line, for brevity and to make it easier for me to
10728 sort my dir-example file in the Texinfo distribution :).

10799 * tests/torture.at (Configuring subdirectories): Require aclocal
10800 1.4, otherwise the test fails, as it does support configure.ac.

10943 $ac_prefix_program.
10946 2002-12-23 Paul Eggert <eggert@twinsun.com>
10948 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10949 innocuous variant befor including <limits.h> or <assert.h>. This
10950 works around a bug reported by Albert Chin: HP-UX 11i
10951 (and earlier versions) have a <limits.h> that declares
10952 gettimeofday and many other functions.
10954 2002-12-03 Paul Eggert <eggert@twinsun.com>
10958 * NEWS, configure.ac: Update version.
10960 * doc/fdl.texi: Upgrade to FDL version 1.2.
10962 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10963 nontrivially in main's body, so that f's external declaration is
10964 not optimized away in AIX. This should fix the bug reported by
10966 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10968 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10969 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10970 defined, to support freestanding compilers. This should fix the
10971 bug reported by Momchil Velkov in
10972 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10974 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10975 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11006 Update from masters.
11008 2002-11-14 Akim Demaille <akim@epita.fr>
11010 * Makefile.maint: Sync with Bison, i.e.:
11011 (po-check): Scan .l and .y files instead of the
11012 .c and the .h files that they generate. This fixes the bug
11013 reported by Tim Van Holder in:
11014 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11015 Look for N_ as well as for _. Try to avoid matching #define for

11031 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11032 than assigning in main, to avoid HP cc +O3 optimizing it away.

11036 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11037 option. Process --recheck after parsing all options. Pass -q
11038 option to configure on --recheck.
11039 (AC_OUTPUT): Pass -q from configure to config.status.
11040 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11041 arguments to record.
11042 * doc/autoconf.texi (config.status Invocation): Document
11043 config.status -q option.
11045 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11047 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11048 Makefile.in if Makefile.am exists.
11049 (output): Strip `.am' from Makefiles. Don't
11050 output AC_CONFIG_FILES if no Makefiles were found.

11070 Reported by Ezra Peisach.
11072 2002-11-05 Akim Demaille <akim@epita.fr>
11074 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11076 We _have_ to stop using the old compatibility scheme that tried to
11077 avoid useless backslashes because Libtool 1.4.3 contains a
11078 AC_DEFINE([error_t], [int],
11079 [Define to a type to use for \`error_t' if it is not
11080 otherwise available.])
11081 We _have_ to quote the single quote and backslashes with \. The
11082 old compatibility scheme saw that ` was backslashed, and therefore
11083 did not quote the single quote. Hence before this patch, Autoconf
11084 was not compatible with Libtool.
11086 2002-11-04 Paul Eggert <eggert@twinsun.com>
11088 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11129 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11130 Make variable, not a shell variable.
11131 Suggested by Bruno Haible.
11133 2002-10-31 Akim Demaille <akim@epita.fr>

11158 Problem reported by Bruno Haible.

11162 * doc/autoconf.texi (Header Templates): Put also in words what the

11446 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11448 * tests/tools.at (autom4te): Now it does exit 1.
11450 2002-10-17 Akim Demaille <akim@epita.fr>
11452 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11453 Fixes the `AC_ARG_VAR' test failures.
11454 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11455 * lib/freeze.mk (check-forbidden-patterns): New.
11456 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11457 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11458 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11460 Reported months ago by H. Merijn Brand.
11462 2002-10-17 Akim Demaille <akim@epita.fr>
11464 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11466 2002-10-16 Paul Eggert <eggert@twinsun.com>
11468 * Makefile.maint (wget_files): Remove ansi2knr.c.
11469 (ansi2knr.c-url_prefix): Remove.
11471 2002-10-16 Akim Demaille <akim@epita.fr>
11473 Because of caching, some files that no longer exist and are no
11474 longer required can still cause errors.
11475 Reported by Alexandre Duret-Lutz.
11477 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11478 to frozen files in @ARGV, as @ARGV must remain being a list of
11479 files. Rather, at M4 call sites, use this...
11480 (&files_to_options): New function.
11481 (&freeze): Use &error.
11482 (&up_to_date): If a file that was included according to the cache
11483 is no longer there, then the output is out dated.
11484 (&main): Don't even check whether a file is up to date is anyway
11486 * tests/tools.at (autom4te cache): New.
11488 2002-10-16 Akim Demaille <akim@epita.fr>
11490 * bin/autoconf.as: Kill dead options.
11491 * bin/autoupdate.in (&parse_args): Kill old options.
11492 * bin/autoreconf.in (&parse_args): Remove dead options.
11494 (&autoreconf): Report the directories we enter *and leave*, so
11495 that error messages can be easily located, and use GNU Make
11496 format, so that Emacs' compile mode understands us.
11497 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11498 if some file was changed instead of `print'.
11499 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11500 (&parse_args): Remove the dead options.
11501 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11502 autoheader's quiet mode.
11503 (AT_CHECK_AUTOUPDATE): Likewise.
11504 * tests/tools.at (autoupdate): Adjust.
11505 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11507 2002-10-11 Akim Demaille <akim@epita.fr>
11509 No longer use CPP to check for the existing of headers: use CC to
11510 check for compilability.
11512 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11513 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
11514 (_AC_CHECK_HEADER_NEW): Rename as...
11515 (AC_CHECK_HEADER): this.
11517 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11518 numbers in the Subject suggestion.
11520 2002-10-11 Akim Demaille <akim@epita.fr>
11522 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11523 Suggest using AC_CHECK_DECLS instead.
11525 2002-10-11 Akim Demaille <akim@epita.fr>
11527 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11530 2002-10-11 Akim Demaille <akim@epita.fr>
11532 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11533 file name to enable parallel executions.
11534 From Sam Varshavchik.
11536 2002-10-08 Akim Demaille <akim@epita.fr>
11538 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11539 aclocal invocation, as Gettext macros might not be visible to
11541 Instead of blindly running autopoint, scan configure.ac (not the
11542 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11543 Reported by Paul D. Smith.
11545 2002-10-08 Paul Eggert <eggert@twinsun.com>
11547 Work around problems found when POSIXLY_CORRECT=1 is set.
11548 None of this seems to have anything to do with POSIX, really,
11549 but it's how Perl getopt works.
11550 * bin/autom4te.in (parse_args): Configure GetOpt with
11552 * doc/autoconf.texi (Invoking autom4te):
11553 --warning -> --warnings.
11554 * lib/autom4te.in: --warning -> --warnings.
11556 2002-09-28 Akim Demaille <akim@epita.fr>
11558 * doc/autoconf.texi (autom4te.cache): New section.
11560 2002-09-28 Akim Demaille <akim@epita.fr>
11562 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11563 (Automake-preselections): Update.
11564 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11566 2002-09-28 Akim Demaille <akim@epita.fr>
11568 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11569 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11570 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11571 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11573 2002-09-28 Akim Demaille <akim@epita.fr>
11575 * tests/torture.at (Configuring subdirectories): Be robust to
11576 users who use config.site to require for a cache: in this case,
11577 the two last configure runs, using two different sets of
11578 arguments, trigger a legitimate error.
11580 2002-09-28 Akim Demaille <akim@epita.fr>
11582 * tests/m4sh.at (Functions Support, Functions and return Support):
11585 2002-09-28 Akim Demaille <akim@epita.fr>
11587 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11588 autoheader are Perl programs.
11589 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11590 (autom4te): Specify that the sources are in the $srcdir.
11591 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11593 2002-09-28 Akim Demaille <akim@epita.fr>

11596 (tm_zone): Move their rules to...
11597 * lib/autoconf/types.m4: here, using AN_ macros.
11598 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11599 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11600 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11601 * lib/autoconf/programs.m4: here.

11603 (ETAGS_FOR_AUTOCONF): New.
11606 2002-09-28 Akim Demaille <akim@epita.fr>

11610 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11611 that were listed in the original autoscan.list.
11612 * lib/autoconf/headers.m4: Similarly with headers.
11613 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11614 (.m4.m4f): Don't pass --prepend-include, since that's done by
11615 tests/autom4te itself.
11616 * lib/autoscan/Makefile.am: Include freeze.mk.
11617 (autoscan.list): New target --this file is no longer a source.
11618 (autoscan.pre): New file.
11620 2002-09-28 Akim Demaille <akim@epita.fr>
11622 * bin/autoscan.in (@kinds): Make them singular.
11624 (&init_tables): When --debug, report the list of rules to ease
11625 tracking changes in autoscan.list.
11626 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11628 2002-09-28 Akim Demaille <akim@epita.fr>
11630 * lib/autoscan/functions, lib/autoscan/headers,
11631 * lib/autoscan/identifiers, lib/autoscan/makevars,
11632 * lib/autoscan/programs: Merge into...
11633 * lib/autoscan/autoscan.list: this.
11634 * bin/autoscan.in (&init_tables): Adjust.
11636 2002-09-28 Akim Demaille <akim@epita.fr>
11638 * lib/autoscan/functions, lib/autoscan/headers,
11639 * lib/autoscan/identifiers, lib/autoscan/makevars,
11640 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11641 `functions' line is now prefixed with `function:'.
11642 * bin/autoscan.in (&init_tables): Adjust.
11644 2002-09-28 Akim Demaille <akim@epita.fr>
11646 From now on, autoscan files must always map a macro name to a
11647 word: there is no `default' macro for autoscan.
11649 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11651 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11654 2002-09-28 Akim Demaille <akim@epita.fr>
11656 * bin/autoscan.in (%c_keywords): Remove.
11657 (&used): Keep only track of the words we might be interested in.
11658 (&output_kind): It is no longer needed to look for non active
11661 2002-09-27 Akim Demaille <akim@epita.fr>
11663 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11664 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11665 * lib/autoscan/functions: Adjust.
11666 * doc/autoconf.texi (Particular Functions): Adjust.
11668 2002-09-27 Akim Demaille <akim@epita.fr>
11670 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11672 Thanks to Bill Moseley and Paul Eggert.
11673 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11674 the tmpdir must be created.
11675 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11676 dir be in the build tree, instead of $TMPDIR.
11678 2002-09-27 Akim Demaille <akim@epita.fr>
11680 * bin/autoscan.in: Improve the comments.
11681 (&parse_args): Drop obsolete undocumented options.
11682 (&output_kind): Output warnings.
11683 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11684 (getwd): Trigger a warning.
11686 2002-09-26 Akim Demaille <akim@epita.fr>
11688 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11689 Reported by Ralf Corsepius.
11690 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11692 2002-09-26 Akim Demaille <akim@epita.fr>
11694 Single suffix rules and seperated dependencies are not portable.
11696 * doc/autoconf.texi (Installation Directory Variables): Update.
11697 (Limitations of Make): Some about `Single Suffix Rules and
11698 Separated Dependencies'.
11699 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11700 (ifnames, autoscan, autom4te): Un-factor into several rules.
11702 2002-09-25 Paul Eggert <eggert@twinsun.com>
11704 * BUGS (Interoperability bugs): New section. Mention libtool
11705 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11707 2002-09-24 Paul Eggert <eggert@twinsun.com>
11709 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11710 make handles suffix-rules differently from GNU make.
11712 * bin/Makefile.am (SUFFIXES, .in): Remove.
11713 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11714 Move the body of the old .in rule here.
11716 2002-09-16 Akim Demaille <akim@epita.fr>
11718 i960 compilers create `b.out' files by default.
11719 Reported by Ralf Corsepius.
11721 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11722 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11724 2002-09-13 Paul Eggert <eggert@twinsun.com>
11726 * doc/autoconf.texi (Particular Headers): Remove obsolete
11727 reference to `struct timezone' in the description of
11730 2002-09-13 Akim Demaille <akim@epita.fr>
11734 * config/config.sub, config/config.guess: Update.
11735 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11736 * Makefile.am: Adjust.
11738 2002-09-13 Akim Demaille <akim@epita.fr>
11740 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11741 reading config.log when the compiler is rejected.
11742 Suggested by Guido Draheim.
11744 2002-09-13 Akim Demaille <akim@epita.fr>
11746 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11747 (chdir_init) might hang when stat'ing mounted directories.
11748 Reported by Vance Shipley.
11750 2002-09-12 Akim Demaille <akim@epita.fr>
11752 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11755 2002-09-12 Akim Demaille <akim@epita.fr>
11757 * doc/autoconf.texi (Defining Symbols): Present two different
11758 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11759 difference between 1 argument calls, and 2-3 argument calls.
11761 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11763 * doc/autoconf.texi: Review grammar and punctuation.
11765 2002-09-11 Paul Eggert <eggert@twinsun.com>
11767 * doc/autoconf.texi: Fix minor formatting, spelling, and
11769 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11770 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11773 2002-09-11 Akim Demaille <akim@epita.fr>
11775 * doc/autoconf.texi (Questions): Rename as...
11777 (Defining Directories): New.
11779 2002-09-09 Akim Demaille <akim@epita.fr>
11781 * doc/autoconf.texi (Making testsuite Scripts): Update.
11782 Suggested by Nishio Futoshi.
11784 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11786 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11787 plain `@' is wanted.
11789 2002-09-09 Akim Demaille <akim@epita.fr>
11791 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11792 `duplicates', since the algorithm was too naive and could keep
11793 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11794 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11795 Reported by Ralf Corsepius.
11796 * tests/torture.at (Configuring subdirectories): Exercise these
11799 2002-09-09 Akim Demaille <akim@epita.fr>
11801 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11802 looking for a replacement file.
11803 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11804 directory is relative.
11805 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11806 directory definition.
11807 Reported by Andreas Schwab and Jim Meyering.
11809 2002-09-06 Akim Demaille <akim@epita.fr>
11811 * doc/autoconf.texi (Setting Output Variables): Clarify what
11812 precious variables are.
11813 Suggested by Pontus Skoeld.
11815 2002-09-05 Akim Demaille <akim@epita.fr>
11817 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11818 (ifnames, autoscan, autom4te): Since we don't only depend on
11819 configure.ac variables (such as VERSION etc.), but also on prefix
11820 and so forth, depend on Makefile, not configure.ac.
11821 Reported by Alexandre Duret-Lutz.
11822 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11824 2002-09-05 Kevin Ryde <user42@zip.com.au>
11826 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11827 doesn't seem to be confined to ia64, just say "some versions".
11829 2002-09-04 Akim Demaille <akim@epita.fr>
11831 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11833 * Makefile.am (maintainer-clean-local): Remove.
11834 (MAINTAINERCLEANFILES): Remove COPYING.
11836 2002-09-03 Paul Eggert <eggert@twinsun.com>
11838 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11839 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11842 2002-09-03 Akim Demaille <akim@epita.fr>
11844 * configure.ac: Bump to 2.53d.
11845 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11846 as of today, on Automake's team suggestion.
11848 2002-09-03 Akim Demaille <akim@epita.fr>
11852 2002-09-02 Akim Demaille <akim@epita.fr>
11854 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11856 * configure.ac: Disable SITE_MACRO_DIR.
11858 2002-09-02 Jim Meyering <meyering@lucent.com>
11860 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11861 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11862 Also, tweak grammar: s/make sure to/be sure to/.
11864 2002-09-02 Paul Eggert <eggert@twinsun.com>
11866 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11867 directory names are generally preferable to physical names.
11869 2002-09-02 Akim Demaille <akim@epita.fr>
11871 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11872 Reported by Raja R. Harinath.
11873 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11874 * bin/autoupdate.in: Use error instead of die.
11876 2002-09-01 Paul Eggert <eggert@twinsun.com>
11878 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11879 ordinary shell concatenation rather than echo+tr+sed command that
11880 runs afoul of a long-line-related sed bug in Solaris 8.
11882 * bin/autoheader.in (parse_args): --warning -> --warnings.
11884 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11885 stdout, as traditional "ls" does.
11886 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11887 _AC_COMPILER_EXEEXT_O): Likewise.
11888 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11890 * bin/autoconf.as: Add --prepend-include option. This patch was
11891 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11892 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11894 * bin/autoconf.in, configure: Regenerate.
11896 * doc/autoconf.texi (Special Shell Variables): Mention
11897 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11899 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11900 MAILPATH and set PS1, PS2, PS4 to default values, to work
11901 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11902 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11903 the Autoconf documentation specifies; fall back to "unset" only if
11904 this fails. Use a shell for-loop for this rather than an m4 loop,
11905 to shorten the output script.
11907 2002-08-30 Paul Eggert <eggert@twinsun.com>
11909 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11910 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11911 for the CDPATH problem. Document PWD.
11912 (Limitations of Builtins): Document the problem that "cd $foo" and
11913 "ls $foo" may refer to different directories in shells conforming
11914 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11915 example, since the old example is now out of date.
11917 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11918 FOO" and "ls FOO" talk about different directories; this catches
11919 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11922 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11923 of rolling our own unset.
11924 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11925 in practice we needn't worry about CDPATH if unset doesn't work.
11927 * Makefile.in, aclocal.m4, bin/Makefile.in,

11951 * lib/Autom4te/General.pm (&xqx): New.
11952 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11953 hand, which is not portable.
11955 * bin/autom4te.in: Use them.
11956 Use &error instead of die.

11962 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the

11968 * doc/autoconf.texi (Invoking autom4te): End the option table,

11990 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11991 * Makefile.am (INSTALL): Use the new macros.

12136 2002-06-27 Paul Eggert <eggert@twinsun.com>
12138 * config/install-sh: Quote $src. Prefer || to test's -o option,
12139 as per "Limitations of Builtins".
12140 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12141 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

12169 * doc/autoconf.texi: Add more dir entries.
12171 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12173 * bin/autom4te.in ($cache): Don't define using `$me', the name

12279 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12280 This improves on an earlier suggestion by H. Peter Anvin.
12282 2002-05-16 Paul Eggert <eggert@twinsun.com>
12284 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12285 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12286 Both macros now accept an optional source-dir arg.
12287 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12289 * NEWS: Document this.
12290 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12292 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12293 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12294 not for GNU extensions; this undoes part of the 2000-11-03 change,
12295 reverting to 2.13-compatible behavior.
12296 Add new optional argument DIR.
12297 (AC_FUNC_FNMATCH_GNU): New macro.
12299 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12301 2002-05-08 Paul Eggert <eggert@twinsun.com>
12303 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12304 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12305 and it causes a 'test' syntax error if it fails.
12306 Bug reported by Stephen Gildea.
12308 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12309 If prototypes are supported, use them to check this at compile-time,
12310 instead of trying to check it at run-time. If we must do a run-time
12311 check, assume that setvbuf is standard when cross-compiling, as
12312 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12313 Bug reported by Paul D. Smith.
12315 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12316 argument specifying location of getloadavg.c. This removes a
12317 FIXME. This idea was taken from Jim Meyering's implementation in
12319 * doc/autoconf.texi (Particular Functions): Document this.
12320 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12321 that's what the code does; this fixes a bug reported by
12324 2002-05-03 Akim Demaille <akim@epita.fr>
12326 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12327 autopoint instead of gettextize.
12328 ($uses_alocal): Rename as...
12329 ($uses_aclocal): this.
12330 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12331 Suggested by Bruno Haible.
12333 2002-05-03 Akim Demaille <akim@epita.fr>
12335 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12337 2002-04-29 Paul Eggert <eggert@twinsun.com>
12339 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12340 files to be 1 second older; just set them to be the same time.
12341 Also, sleep 1 second after the first aclocal, to work around
12342 problems with sub-second time stamps on the input files.
12344 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12346 * doc/autoconf.texi: Mention "set -e -x" lossage
12347 under node "Limitations of Builtins".
12349 2002-04-29 Akim Demaille <akim@epita.fr>
12351 * doc/install.texi: Better wording for setting variables when
12353 From Christian Cornelssen.
12355 2002-04-29 Akim Demaille <akim@epita.fr>
12357 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12358 of lack of $LINENO support, then the test will compare the $LINENO
12359 in testsuite vs. the lineno in the test file. This is wrong, of
12361 Be sure to protect it.
12362 Reported by Patrick Welche.
12364 2002-04-25 Akim Demaille <akim@epita.fr>
12366 * doc/autoconf.texi (Obsolete Macros): Typo.
12367 Reported by Vladimir Volovich.
12369 2002-04-25 Akim Demaille <akim@epita.fr>
12371 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12372 than some of the input files, hence, on the second run of aclocal,
12373 if some of its input are younger, make them older.
12374 Suggested by Paul Eggert.
12376 2002-04-25 Akim Demaille <akim@epita.fr>
12378 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12383 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12384 and ac_subst_vars be sh variables containing the list of
12385 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12387 (_AC_INIT_PREPARE): Use them to log them.
12388 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12389 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12390 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12391 _AC_SUBST_FILES and _AC_SUBST_VARS.
12392 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12394 2002-04-24 Akim Demaille <akim@epita.fr>
12396 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12397 autoheader, so that automake does not complain about a missing
12398 config.h.in that was to be created.
12400 2002-04-23 Akim Demaille <akim@epita.fr>
12402 * bin/autoheader.in (parse_args): --warning takes an argument.
12405 2002-04-22 Peter Eisentraut <peter_e@gmx.net>

12452 Minor spelling and grammar fixes.
12454 * doc/autoconf.texi: Follow the outline suggested in the GNU
12455 Sample Texts sections of the Texinfo 4.2 manual. Most
12456 importantly, this makes sure that the copyright notices appear in
12457 all output formats. You probably need Texinfo 4.2 to generate

12497 * doc/autoconf.texi (Shell Substitutions): Explain it.
12498 From Oliver Kiddle and Peter Stephenson.
12500 Have M4sh perform minimal shell sanitizing.
12502 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12504 (_AS_PREPARE): this new macro.
12506 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12507 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12509 Adjust Autoconf and Autotest.
12511 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12512 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12513 * lib/autotest/general.m4 (AT_INIT): Likewise.
12514 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

12518 Use this M4sh to generate Autoconf's shell scripts.
12520 * tests/wrapsh.as: New, precursor of wrapsh.in.
12521 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12522 on Autotest and M4sh.
12523 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12524 (wrapsh.in): New target.
12525 * bin/autoconf.as: New, precursor of autoconf.in.
12526 (autoconf.in): New target.

12558 Use dnl, not the KILL diversion.
12560 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12561 (AC_CONFIG_LINKS): here.
12563 Don't use the KILL diversion, as it kills spurious output, which
12564 results in failures being hidden.
12565 Use m4_defn where appropriate.
12566 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12567 after the second argument.
12569 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12570 syntax, as it is provided by M4sugar.

12612 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12613 to avoid versions of HP C which don't allow that.
12615 2002-03-27 Paul Eggert <eggert@twinsun.com>
12617 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12618 (AS_SHELL_SANITIZE): Invoke it.

12631 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12632 as POSIX requires, as it doesn't work with Zsh.
12633 * doc/autoconf.texi (Assignments): Document the problem.
12635 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12637 * doc/autoconf.texi (Limitations of Make): Mention more issue
12638 about VPATH, overriding of macros in sub-makes, and handling of
12641 2002-03-21 Paul Eggert <eggert@twinsun.com>
12643 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12644 problem with here-document buffer boundaries.
12646 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12647 when reinvoking the shell, to work around problems with installers
12648 who put strange things like "cd" commands in their environments.

12668 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12672 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12673 (Limitations of Usual Tools): Add mkdir section.
12675 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12676 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12677 back on AS_DIRNAME to compute prefixes otherwise; this is
12678 roughly what mkinstalldirs does. That way, we need not have
12679 our own filename disassembler. The old disassembler did not
12680 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12682 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12683 Create at_test_all by a series of assignments,
12684 not by a single assignment of a long string. The latter causes ksh
12685 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12686 presumably because of a buffer overrun.
12688 2002-03-14 Paul Eggert <eggert@twinsun.com>
12690 * lib/autotest/general.m4 (at_times_skip):
12691 Renamed from at_times. Now a boolean.
12692 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12693 says 'times: not found'.

12734 subdirectory should exist.
12736 2002-03-08 Akim Demaille <akim@epita.fr>
12738 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12740 2002-03-08 Akim Demaille <akim@epita.fr>
12742 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12743 aliases the actual variables, and modifications of the former
12746 2002-03-08 Akim Demaille <akim@epita.fr>
12748 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12749 because of C-c: have m4 output in tmp files, then mv them.

12783 * doc/autoconf.texi (Transforming Names): Equality between target
12784 and host is irrelevant.
12785 (Specifying Names, Canonicalizing): Remove all references to the
12786 backward compatibility hooks. Rather, collect them all into...
12787 (Hosts and Cross-Compilation): this new section.
12788 * doc/install.texi (System Type): Ditto.
12789 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12790 that `--host' implies cross-compilation.

12794 * doc/autoconf.texi (Evaluation Macros): New.
12795 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12797 (_m4_foreach): Define the variant with immediate evaluation so
12798 that it contains exactly the items, not an expression which
12799 evaluation is the current item.
12800 (m4_re_string, m4_re_word): Don't over quote them.
12802 2002-03-04 Akim Demaille <akim@epita.fr>
12804 Instead of having stacking `shift's evaluated at the end, let
12805 `foreach' loops immediately evaluate them.
12807 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12808 $*. This is the n-th time I change my mind, but hopefully this is
12811 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12813 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12814 it was only a hack for m4_text_wrap.
12815 (m4_car2): Remove, replaced by...
12817 (_m4_foreach): Adjust.
12818 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12819 m4_bpatsubst for clarification.

12926 Implement `autom4te --freeze'.
12928 * bin/autom4te.in (&freeze): New.
12929 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12930 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12932 2002-02-05 Akim Demaille <akim@epita.fr>
12934 * bin/autom4te.in (&parse_args): Implement `frozen files are
12935 optional are the sum of the previous files on the command line'.
12936 Also, pass `--reload-state=' on them, so...
12937 (handle_m4): don't.
12938 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12939 (M4sh): Rely on M4sugar.
12940 (Autotest, M4sh, M4sugar): Use frozen files.
12942 2002-01-31 Akim Demaille <akim@epita.fr>
12944 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12945 * doc/autoconf.texi (Initializing configure): Adjust.
12947 2002-01-30 Akim Demaille <akim@epita.fr>
12949 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12950 alphanumeric to `-' instead of `_'.
12952 2002-01-30 Akim Demaille <akim@epita.fr>
12954 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12955 for plain code, the other for cross-compilation code. The latter
12956 is now run with GCC only.
12957 * doc/autoconf.texi (Compilers and Preprocessors): New.
12959 2002-01-30 Akim Demaille <akim@epita.fr>
12961 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

12964 change AC_INIT default values.
12966 2002-01-29 Akim Demaille <akim@epita.fr>
12968 * tests/torture.at (Configuring subdirectories): Use configure.in,
12969 so that aclocal 1.4 works.
12970 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12972 2002-01-28 Akim Demaille <akim@epita.fr>
12974 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12977 2002-01-28 Akim Demaille <akim@epita.fr>
12979 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12980 AUTOTEST_PATH *after* it was set.
12981 Don't put `.' in the PATH: the user should be precise and `./' if
12982 needed. In addition, given that the test suite does some `cd', if
12983 `.' is in the path, the `tested programs' sections will report
12984 programs found in the test suite's directory, while during the
12985 tests (performed in their own directory), these programs are no
12986 longer visible. In other words, the results is confusing and
12988 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
12990 2002-01-24 Akim Demaille <akim@epita.fr>
12994 2002-01-24 Akim Demaille <akim@epita.fr>

12997 * doc/autoconf.texi: Finally add Akim as an author.
12999 2002-01-24 Akim Demaille <akim@epita.fr>
13001 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13002 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13003 Bourne. Use /bin/sh.
13004 From Andreas Buening.
13006 2002-01-24 Akim Demaille <akim@epita.fr>
13008 * config/config.guess, config/config.sub, config/texinfo.tex:
13009 Update from masters.
13011 2002-01-24 Akim Demaille <akim@epita.fr>

13016 * config/missing.m4, config/sanity.m4, config/select.m4,
13017 * config/strip.m4: Remove, to ease sync'ing with any version of

13022 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13023 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13024 Reported by Geir Ove Myhr.
13026 2002-01-21 Akim Demaille <akim@epita.fr>

13030 2002-01-21 Akim Demaille <akim@epita.fr>
13032 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13033 message on invalid options.
13034 * bin/autom4te.in (parse_args): Don't use
13035 Autoconf::General::getopt with non valid options.
13037 2002-01-17 Jim Meyering <meyering@lucent.com>
13039 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13040 $ac_cv_exeext so we don't use an old, invalid, cached value.
13042 2002-01-11 Akim Demaille <akim@epita.fr>
13044 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

13053 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13054 package.m4, since is really depends upon configure.ac, not
13056 * doc/autoconf.texi (testsuite Scripts): Adjust.
13057 * tests/Makefile.am (package.m4): New.
13058 EXTRA_DIST it since its a source.
13060 2002-01-06 Akim Demaille <akim@epita.fr>
13062 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13063 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13064 and PACKAGE_BUGREPORT from here...
13065 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13067 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13068 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13069 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13070 * tests/tools.at (autoheader): Adjust.
13071 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13073 2002-01-06 Akim Demaille <akim@epita.fr>

13088 2001-12-17 Jim Meyering <meyering@lucent.com>
13090 * doc/autoconf.texi (New Macros): Tweak wording.
13092 2001-12-14 Akim Demaille <akim@epita.fr>
13094 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13095 trailing files, don't apply `-rf' to files which might not be
13096 created by configure (core, core.*, and *.core), but just `rm -f'.
13097 Suggested by Jonathan Kamens.
13099 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13101 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13103 2001-12-14 Akim Demaille <akim@epita.fr>
13105 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13107 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13109 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13110 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13111 abs_srcdir, top_srcpath to abs_top_srcdir.
13112 (_AC_OUTPUT_FILES): Adjust.
13113 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13114 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13115 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13117 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

13123 2001-12-12 Kevin Ryde <user42@zip.com.au>
13125 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13126 forbidden file descriptors table.
13128 2001-11-26 Akim Demaille <akim@epita.fr>
13130 * bin/autoscan.in (%c_keywords): Build it at top level.
13131 Map to 1 in order to simplify its uses.
13133 2001-11-26 Akim Demaille <akim@epita.fr>
13135 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13136 Remove $filepath, useless.
13137 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13138 variables, they are really part of the tokens.
13139 Split the input line on spaces and then look for tokens.
13140 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13141 because of `lex$U.$(OBJEXT)'.
13142 (&scan_files): Use "@list" instead of join.
13143 * doc/Makefile.am (CLEANFILES): Add *.fns.
13145 2001-11-26 Akim Demaille <akim@epita.fr>

13148 Remove, replaced by...
13149 * tests/wrappl.in: Be common for all the Perl executables.
13150 In particular autoscan and autoheader want -I.
13151 * configure.ac: Adjust.
13152 * lib/autoscan/headers: errno.h is portable.
13154 2001-11-26 Akim Demaille <akim@epita.fr>
13156 * bin/autoscan.in (used): New.
13159 2001-11-26 Akim Demaille <akim@epita.fr>
13161 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13163 (&scan_sh_file): Remove a duplicate pattern.
13164 (&check_configure_ac): Use long options.
13165 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

13170 Before, having a line containing the opening of a multi line
13171 comment made the whole line be ignored.
13173 2001-11-26 Akim Demaille <akim@epita.fr>
13175 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13176 (testsuite Scripts): Be one of its subsection.
13177 (Autotest Logs): New.

13181 Test groups are now run two directories deeper.
13183 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13184 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13186 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13187 top_srcdir, builddir and top_builddir.
13188 Use `at_*dir' relatively to the directory containing the
13189 suite, use `*dir' when relatively to the current group dir.
13191 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13193 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13194 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13195 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13198 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13200 * doc/autoconf.texi (Using System Type): Add an example of `case
13201 $host' usage so people quit using `case $target' everywhere.
13203 2001-11-22 Akim Demaille <akim@epita.fr>
13205 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13206 spotted by Jim Meyering.
13208 2001-11-16 Paul Eggert <eggert@twinsun.com>
13210 This patch implements a `long double' suggestion by Oliver Kiddle.
13212 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13213 static, to catch errors if the value isn't known at compile-time
13214 and the compiler supports dynamic arrays. Change its name from
13215 `_array_' to `test_array' to avoid potential name clashes.
13216 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13217 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13218 better than double. Catch a bug in GCC 2.95.2 x86.
13219 * doc/autoconf.texi (C Compiler): Document the above.
13222 2001-11-13 Akim Demaille <akim@epita.fr>
13224 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13226 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13228 2001-11-13 Akim Demaille <akim@epita.fr>
13230 * lib/autotest/general.m4 (AT_INIT): After having run the test
13231 group, go back to the initial directory, not to at_suite_dir.
13233 2001-11-13 Akim Demaille <akim@epita.fr>
13235 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13236 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13237 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13239 (AT_CHECK_CONFIGURE): Use absolute paths.
13240 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13241 The problem is still the old one: there is no means in M4 (that I
13242 know about) to create a defining macro, because there is no means
13243 to create `$1' etc., therefore, the defining macro ``swallows''
13244 all the arguments meant to the defined macro.
13246 2001-11-13 Akim Demaille <akim@epita.fr>
13248 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13249 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13251 * tests/aclocal.m4: Remove, as it is no longer used.
13253 2001-11-13 Akim Demaille <akim@epita.fr>
13255 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13256 variable names when referring to a single test group, or to
13257 `suite' when referring to the whole test suite.
13258 `at_last_test' is removed: m4 compute at_format itself.
13259 (at_stdout, at_stder1, at_stderr): New variables.
13260 (AT_CHECK): Use them.
13262 2001-11-13 Akim Demaille <akim@epita.fr>
13264 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13266 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13267 Do it as soon as a test fails, don't wait till the end of the test
13269 Don't remove $as_me.[0-9]*, since these files no longer exist.
13271 2001-11-13 Akim Demaille <akim@epita.fr>
13273 * tests/tools.at: Use absolute paths, since we are no longer run
13276 2001-11-13 Akim Demaille <akim@epita.fr>
13278 Now that tests are running in their own private dir, there is no
13279 need to list the files to remove at the end of tests groups.
13281 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13282 (AT_data_files, at_data_files): Remove.
13283 (AT_CLEANUP, AT_DATA): Simplify.
13285 Remove the group dir if !debug && !failed.
13286 * tests/atspecific.m4: Adjust.
13288 2001-11-13 Akim Demaille <akim@epita.fr>
13290 Start a new layout for Autotest: `testsuite' creates
13291 `testsuite.dir' in which the at-check-line etc. files are to be
13292 found, and `testsuite.dir/003' where the test group 3 is run.
13294 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13295 at_check_line_file, at_format, at_test_normalized, at_group_dir
13297 Create the directories.
13298 Use absolute paths for at- files.
13299 (AT_CHECK): Adjust.
13301 2001-11-11 Michael Matz <matz@kde.org>
13303 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13305 (m4_car): Properly quote arguments.
13307 2001-11-13 Akim Demaille <akim@epita.fr>
13309 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13310 with stricter rules on LIBOBJS.
13312 2001-11-12 Paul Eggert <eggert@twinsun.com>
13314 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13315 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13318 2001-11-12 Akim Demaille <akim@epita.fr>
13320 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13322 2001-11-12 Akim Demaille <akim@epita.fr>
13324 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13325 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13326 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13327 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13328 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13329 specify to what the macro should be defined (typically to 1).
13331 2001-11-12 Akim Demaille <akim@epita.fr>
13333 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13336 2001-11-12 Akim Demaille <akim@epita.fr>
13338 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13339 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13340 definition used by Automake where LEX is +/- "${missing} lex" and
13341 `missing' itself contains variables.
13343 2001-11-12 Akim Demaille <akim@epita.fr>
13345 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13346 Now that M4sh pushes BODY, the comments were output at the end of
13349 2001-11-08 Akim Demaille <akim@epita.fr>
13351 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13352 that we can trace macros from aclocal.m4.
13353 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13354 obsoleted, and redirect to the former anyway.
13355 Reported by Ralf Corsepius.
13357 2001-11-08 Akim Demaille <akim@epita.fr>
13359 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13360 processed only if present.
13361 * tests/torture.at (Configuring subdirectories): Use autoreconf
13362 instead of successive calls to autoconf.
13363 Add a nonexistent subdirectory to exercise the patch above.
13364 Reported by Ralf Corsepius.
13366 2001-11-08 Kevin Ryde <user42@zip.com.au>
13368 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13369 doesn't accept .S files.
13371 2001-11-07 Akim Demaille <akim@epita.fr>
13373 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

13375 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13376 * bin/autom4te.in (warn_forbidden): New.
13377 (handle_output): Use it.
13378 Read m4_pattern_forbid with messages.
13380 2001-11-05 Akim Demaille <akim@epita.fr>
13382 * bin/autom4te.in (--normalize): Remove.
13383 * lib/autom4te.in: Adjust.
13385 2001-11-05 Akim Demaille <akim@epita.fr>
13387 * tests/Makefile.am (testsuite): Rename this target as...
13388 ($(TESTSUITE)): this.
13391 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13393 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13394 the --prefix option, also remove it's argument.
13396 2001-11-05 Akim Demaille <akim@epita.fr>
13398 * doc/autoconf.texi (testsuite Invocation): Update.
13399 (Writing testsuite.at): Update.
13401 2001-11-03 Akim Demaille <akim@epita.fr>
13403 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13405 2001-11-03 Akim Demaille <akim@epita.fr>
13407 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13408 (&file_name_is_absolute): New, wrappers around routines from
13410 Use and export them.
13411 (&find_configure_ac): Optionally take a directory where to look at.
13412 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13414 Default @ARGV to `.', not find_configure_ac.
13415 (&autoreconf): Argument is a directory.
13416 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13417 * doc/autoconf.texi (autoreconf Invocation): Update.
13419 2001-11-03 Akim Demaille <akim@epita.fr>
13421 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13422 (@export_forward_subs): New.
13423 Add basename, dirname, and fileparse.
13425 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13426 Don't look for aclocal flags if we already know aclocal is not
13428 Move aclocal.m4t only if it exists.
13429 Reported by Ezra Peisach.
13431 2001-11-03 Akim Demaille <akim@epita.fr>
13433 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13434 passed on command line, defaulting to ./configure.ac if present.
13435 (&maybe_autoreconf, File::Find): Remove, unused.
13436 (&autoreconf): If autoconf is not used, don't try to trace.
13438 2001-11-02 Akim Demaille <akim@epita.fr>
13440 * configure.ac: Bump to 2.52g.
13442 2001-11-02 Akim Demaille <akim@epita.fr>
13446 2001-11-02 Akim Demaille <akim@epita.fr>
13448 * config/config.guess, config/config.sub, doc/standards.texi:
13449 * config/lispdir.m4: Update from masters.
13450 * configure.ac: Bump to 2.52f.
13452 2001-11-02 Akim Demaille <akim@epita.fr>
13454 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13455 Don't run aclocal when aclocal.m4 is not from aclocal.
13457 Don't run libtoolize and gettextize if --install is not given.
13459 2001-11-01 Paul Eggert <eggert@twinsun.com>
13461 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13462 be invoked before _AS_LINENO_PREPARE.
13463 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13464 than character ranges.
13466 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13467 invoking AS_BASENAME. Set the locale variables to 'C' if
13468 possible, as POSIX requires this to get the traditional
13470 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13472 2001-10-31 Paul Eggert <eggert@twinsun.com>
13474 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13475 with {}, as that triggers a bug in Bash 2.05.
13477 (_AS_LINENO_PREPARE): Use Sed rather than
13478 Awk. Fix the sed prepass to work even if there are multiple
13479 instances of $LINENO on the same line. Do not substitute for
13480 other variables like $LINENOT. Do not check file dates; such a
13481 check is unreliable on sufficiently fast machines, and removing
13482 the check makes the code simpler and more reliable. Check for
13483 output and chmod failures.
13485 * doc/autoconf.texi (Special Shell Variables): Document
13488 2001-10-31 Akim Demaille <akim@epita.fr>
13490 * tests/Makefile.am (atconfig): Remove this target, Automake
13493 2001-10-31 Akim Demaille <akim@epita.fr>
13495 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13496 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13497 provided, while it is optional.
13498 * configure.ac: Adjust.
13500 2001-10-26 Paul Eggert <eggert@twinsun.com>
13502 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13503 lib/Autom4te/Struct.pm:
13504 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13507 * doc/autoconf.texi (Special Shell Variables): Document some
13508 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13510 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13511 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13512 eval $LINENO is not portable in practice.
13514 2001-10-24 Akim Demaille <akim@epita.fr>
13516 * lib/Autom4te/General.pm (backname): New.
13518 2001-10-24 Akim Demaille <akim@epita.fr>

13526 2.05's use of ANSI quoting in its `set' builtin.
13528 2001-10-22 Paul Eggert <eggert@twinsun.com>
13530 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13531 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13532 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13533 POSIX decided to standardize on the int flavor of strerror_r.
13534 Always do char* test, as there's no reason not to.
13535 Assign to a char* var, to catch strerror_r that returns int*.
13537 * doc/autoconf.texi (Particular Functions):
13538 Document the above changes. Also, document the fact that
13539 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13541 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13543 2001-10-20 Akim Demaille <akim@epita.fr>

13550 * lib/Autom4te/General.pm (&update_file): If destination is
13551 unchanged, remove the source.
13552 (&up_to_date_p): Don't be verbose, be debug.
13553 * bin/autoreconf.in: No longer support --m4dir.
13554 (&autoreconf): Display the full path of the configure.ac we are
13556 Trace it only once.
13557 Be sure to honor --force with gettextize.
13558 Always run aclocal.
13559 * doc/autoconf.texi: Adjust.
13561 2001-10-20 Akim Demaille <akim@epita.fr>
13563 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13565 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13566 `intl' is already present, as it refuses unless --force.
13567 (&parse_args): Use -I, --include instead of the old Autoconf
13569 ($localdir, $autoconf_dir): Remove.
13571 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13573 2001-10-19 Jens Petersen <petersen@redhat.com>
13575 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13591 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13593 * bin/autoreconf.in (autoreconf): Display the path to the
13594 configure.ac being studied.
13596 2001-10-18 Paul Eggert <eggert@twinsun.com>
13598 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13599 long, to work around a bug in the HP C compiler version HP92453-01
13602 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13603 (AS_BASENAME_EXPR): New macro.
13604 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13605 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13606 and fall back on 'sed' only if the other two fail. This makes
13607 AS_BASENAME act more like AS_DIRNAME.
13608 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13609 contains white space.
13610 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13611 Use AS_DIRNAME, since I think it's now DOS-friendly.
13612 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13613 Allow "dirname //FOO" to return either / or //, as POSIX allows

13618 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13624 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13664 bother with $force since...
13665 * lib/Autom4te/General.pm: does.
13667 2001-10-08 Akim Demaille <akim@epita.fr>
13669 * bin/autoreconf.in: Rewrite in Perl.
13670 * configure.ac: Adjust.

13754 empty, and if we can find a shell that does support LINENO,
13755 then set CONFIG_SHELL to that shell and then re-execute
13756 ourselves with CONFIG_SHELL.
13758 2001-10-05 Paul Eggert <eggert@twinsun.com>
13760 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13761 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13832 Don't use nested parenthesization. This patch was originally
13833 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13834 but somehow it didn't get incorporated then.
13835 * doc/autoconf.texi (Limitations of Usual Tools):

13841 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13842 Check for `expr' arithmetic overflow, and for compilation failure,
13843 and invoke a new argument $4 if either is discovered.
13844 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13845 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13847 2001-09-28 Akim Demaille <akim@epita.fr>
13849 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

13879 * tests/fortran.at (GNU Fortran 77): there.

14074 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14076 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14077 Do not pass a first argument with leading '-'
14078 to expr, by parenthesizing initial integers that might be negative.
14080 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14081 now merely checks whether it is an error to pass an argument
14084 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14085 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14086 whether it is a (compile-time) error to pass an argument to

14104 Add test for AS_BASENAME.
14105 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14106 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14107 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14108 * tests/base.at: Fixed the expected responses. The old ones were
14110 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14111 the documentation claims it should (and how it behaved in 2.13).
14113 2001-09-18 Akim Demaille <akim@epita.fr>
14115 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14116 the AC_CONFIG_COMMANDS invocation.

14119 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14120 No longer to be shipped.

14124 Use `m4_PACKAGE_STRING'.
14125 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14126 the only optional argument is the name of the test suite.
14127 Expect `package.m4' to define the package signature.
14128 * lib/autom4te.in (Autotest): Add `package.m4?'.
14129 * tests/Makefile.am (package.m4): New.

14151 the expression in an extra function before these includes. Call
14152 fprintf "%d" only after ensuring the argument is of type 'int'.
14153 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14155 2001-09-17 Paul Eggert <eggert@twinsun.com>
14157 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14158 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14159 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14160 when they don't exist.
14162 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14163 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14166 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14167 version with the version used by fileutils 4.1, except use

14213 * lib/autotest/general.m4 (AT_INIT): Create and remove
14214 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

14219 * tests/mktests.sh: Don't output banners for empty test files.

14325 2001-09-05 Akim Demaille <akim@epita.fr>
14327 Be ready to handle filenames as stupid as `dnl.at', for if even
14328 the maintainer is dumb enough to do that...
14330 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14331 excellence in M4 quotation: consider `__file__' is active.
14333 And BTW, when invoking m4, pass the --include in the right order:

14359 2001-09-05 Akim Demaille <akim@epita.fr>
14361 CVS GNU M4 doesn't like `undefine(undefined)'.
14363 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14364 New, extracted from main.
14365 Use IO::File wherever possible.
14366 (input.m4): Be constant, use -I instead of hard coding $tmp.
14367 Therefore be a quoted heredoc.
14368 Don't invoke `_au_disable', since ac was not loaded, but just

14394 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14396 2001-08-31 Akim Demaille <akim@epita.fr>
14398 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14399 (testsuite Scripts): There is no such thing as `atconfig.in'.
14400 And actually one diagram is missing: test suite runtime.
14402 2001-08-31 Akim Demaille <akim@epita.fr>
14404 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14407 2001-08-31 Akim Demaille <akim@epita.fr>
14409 * bin/autoupdate.in (@include): `installcheck' revealed the path
14410 to m4sugar was lacking!
14412 2001-08-31 Akim Demaille <akim@epita.fr>
14414 * man/Makefile.am (.x.1): We really have to pass
14415 autom4te_perllibdir.

14425 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14426 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14427 Use directly autom4te, not autoconf.

14430 2001-08-31 Akim Demaille <akim@epita.fr>

14452 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14453 (autoheader): Pass --force since the test suite goes too fast for
14455 Adjust to the new autoheader messages.

14469 Drop AC_MACRODIR dead for real.
14470 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14471 `autoheader: `config.hin' is created'.
14472 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14474 2001-08-31 Akim Demaille <akim@epita.fr>
14476 * bin/autoheader.in: Rewrite in Perl.
14477 * tests/autoheader: Adjust.

14482 Map --localdir, --autoconf-dir onto it.
14483 Forward autom4te's options instead of interpreting them.
14484 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14485 There is no such envvar since the inception of autom4te.cfg.
14486 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14487 * bin/autoupdate.in: Adjust, and perform more control.

14489 * tests/autoconf: Dittowise.
14491 2001-08-31 Akim Demaille <akim@epita.fr>

14507 * lib/Autom4te/General.pm (&find_peer): Remove.
14508 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14509 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14510 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14511 find the executables for it.
14512 * tests/Makefile.am: Major cleanup. Too lazy to document...
14513 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14515 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14516 indeed related to running the test suite, while passing
14517 --autoconf-dir and others is related to running non installed
14518 Autoconf executables. So don't do that, leave it to...
14519 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14520 * tests/autoscan: New.
14521 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14538 Suggested by Paul Eggert.
14540 2001-08-29 Akim Demaille <akim@epita.fr>
14542 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14543 download in a tmp dir.
14545 2001-08-29 Akim Demaille <akim@epita.fr>
14547 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14808 * NEWS, README, README-alpha, TODO, tests/README: This package is
14809 `Autoconf', not `autoconf' (the executable).
14811 2001-08-20 Akim Demaille <akim@epita.fr>
14813 Info readers seem to need `Index' in the index node title :(
14815 * doc/autoconf.texi: Reverse the 2001-08-15 change which

14866 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

14929 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

14947 * doc/autoconf.texi: Work around Texinfo buglets.
14948 (Transformation Rules): One example is enough, users are expected
14949 to have their brains on. And BTW, use DESTDIR.
14950 (dvar): New macro. Use it.
14952 2001-08-17 Akim Demaille <akim@epita.fr>
14954 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15007 autom4te.cache (it's a directory, not a file.
15008 * Makefile.am: Ditto (but maintainer-clean-local).
15010 2001-08-15 Akim Demaille <akim@epita.fr>
15012 * bin/autom4te.in (@m4_warning): New.
15013 (&handle_m4): Use it.
15014 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15015 warnings are issued at each run.
15016 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15017 is in the src tree.
15019 2001-08-15 Akim Demaille <akim@epita.fr>
15021 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15022 don't waste time running `autoupdate --version' works.
15023 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15025 2001-08-13 Akim Demaille <akim@epita.fr>

15084 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15086 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15087 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15088 * doc/autoconf.texi (C Compiler Characteristics): Update
15089 documentation for AC_C_BIGENDIAN.

15094 magic values from an object file when cross-compiling.
15095 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15097 2001-08-10 Akim Demaille <akim@epita.fr>
15099 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15101 Suggested by Russ Allbery.
15103 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15105 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15106 current $prefix to the sub-configures.
15108 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15110 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15111 extension (needed on BeOS). Reported by Guido van Rossum.
15113 2001-08-09 Akim Demaille <akim@epita.fr>
15115 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15117 2001-08-07 Akim Demaille <akim@epita.fr>
15119 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15121 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15122 No need to remove the files before and after the each test, before
15123 each test and at the end of the suite is enough.
15124 Display only the children `times', not the shell's.
15125 If the test failed or was skipped, at-times is not available.
15127 2001-08-07 Akim Demaille <akim@epita.fr>
15129 Always produce testsuite.log, including when there are no
15130 failures. This helps getting information on skipped tests, and
15131 duration of the tests. Err, implement the latter btw.
15133 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15134 Dump information on the first run of each test.
15135 (AT_CLEANUP): Create `at-times' containing the duration of the
15138 2001-08-07 Akim Demaille <akim@epita.fr>
15140 The use of `dumpstat' revealed that `len' was used although it
15141 should not. m4_text_wrap was using it, but in the Autoconf world
15142 where it is legal. Hence (i) test M4sh in its own world, not
15143 Autoconf's, and (ii), ahem, fix the bug :)
15145 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15146 does not like `' instead of [].
15147 (AT_INIT): Forbid `^_?AT_'.
15148 And don't output such tokens.
15149 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15150 `script.as', and `autom4te.cache'.
15151 Remove `empty' and `macro' which are no longer used.
15152 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15153 * tests/m4sugar.at: Use it.
15154 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15156 2001-08-07 Akim Demaille <akim@epita.fr>

15160 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15162 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15164 2001-08-04 Akim Demaille <akim@epita.fr>
15166 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15167 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15169 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15170 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15171 (AC_F77_MAIN): Likewise.
15173 2001-08-04 Akim Demaille <akim@epita.fr>
15175 Don't rely on M4sugar outputting the patterns in files, since we
15176 might process the output _without_ running m4, hence without these
15179 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15180 * bin/autom4te.in (@Request::includes): Remove, unused.
15181 (@Request::source): Rename as...
15182 (@Request::input): this.
15183 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15184 (&handle_output): Fetch the patterns from the traces.
15185 `$forbidden' and `$allowed' are constant: use m//o.
15186 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15187 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15189 2001-08-04 Akim Demaille <akim@epita.fr>
15191 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15192 autoconf', i.e., in addition to caching traces, cache the output.
15194 * bin/autom4te.in (Request::cache): Rename as...
15195 (Request::id): this.
15196 ($cache, $icache, $tcache, $ocache): New.
15197 (&handle_m4): Save M4 output in the cache instead of $tmp.
15198 (&handle_output): Adjust.
15199 (&up_to_date_p): Check that the output cache is up to date too.
15200 (top level): Run `&handle_m4' iff force or the cache is invalid.
15201 Run `&handle_output' if the output cache is more recent.
15203 2001-08-04 Akim Demaille <akim@epita.fr>
15205 * bin/autom4te.in ($force): New.
15206 (&parse_args, &print_usage): -f, --force is a new option.
15207 (&handle_output): CPP directives might have spaces after `#'.
15208 (&parse_args): The first file only can be frozen.
15210 2001-08-04 Akim Demaille <akim@epita.fr>
15212 Don't let autom4te compute the `include' traces several times:
15213 first check that the trace cache file is up to date, and then
15214 compare its timestamp with that of the output.
15216 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15217 the preamble. Don't require 5.005 as Autom4te::General does it,
15218 and better yet (use `use', not `require'!).
15219 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15220 Class::Struct as Autom4te::Struct.
15221 * lib/Autom4te/General.pm (File::stat): Use it.
15222 (&mtime): New, export it.
15223 * bin/autom4te.in: Use it.
15224 Declare `$req' is invalid if it is outdated.
15225 Don't declare it valid before saving it if something went wrong.
15227 2001-08-04 Akim Demaille <akim@epita.fr>

15230 must be proposed to the users.
15232 * bin/autom4te.in (@required_trace): Remove.
15234 (&parse_args, &print_usage): -p, --preselect is a new option.

15240 * tests/tools.at (autoconf --trace: user macros): Check traces on
15241 macros invoked without arguments, and macros invoked with multiple

15251 * bin/autoconf.in ($@): Work around the usual sh bug.
15254 2001-08-03 Akim Demaille <akim@epita.fr>
15256 Clean up the handling of the M4 builtins tracing exception.

15261 (@m4_builtin): this.
15262 (%m4_builtin_alternate_name): New.
15263 (&parse_args): Complete the trace requests with alternate names.

15270 m4_if, and m4_wrap.
15272 2001-08-03 Akim Demaille <akim@epita.fr>
15274 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15275 (m4_divert_pop): Dump the whole diversion stack when a diversion
15277 * bin/autom4te.in (&handle_output): Remember of the first
15278 occurrence of a possibly undefined macro, not the last.
