1054 with Bash 2.03 printf.
1055 (Substitute and define special characters):
1056 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
1058 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
1060 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
1061 input from /dev/null in awk test, so even Solaris /usr/bin/awk
1062 will not wait for input with a script containing only a BEGIN
1065 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1067 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
1071 2007-02-02 Eric Blake <ebb9@byu.net>
1073 * NEWS: Update copyright.
1075 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
1077 * configure.ac: Update error message.
1078 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

1085 * THANKS (people): Update.
1087 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1089 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1091 (Shell Substitutions): Note problems with @{var:=value} etc.
1092 Add a new section for problems with @{#var} etc. Problem noted
1093 by Ralf Wildenhues. See:

1096 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1098 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1099 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1100 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1101 substitution will still be done by the special code.
1102 Report by Jim Meyering.
1104 * doc/autoconf.texi (File System Conventions): Mention that
1105 $PATH_SEPARATOR is for the build system only.
1106 Report by Keith Marshall.
1108 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1110 * doc/autoconf.texi (Setting Output Variables): Mention that
1111 all non-NUL characters are ok in substituted values.
1112 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
1113 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
1114 carriage return for $AWK, needed for BSD awk.
1115 * tests/torture.at (Substitute and define special characters):
1116 Test all 8 bit non-NUL characters.
1117 Report against Automake by Patrick Welche.
1119 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1121 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1123 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1125 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1126 early on the reader side, drop stderr of the input to avoid
1127 `broken pipe' error output; this may happen even with shell
1128 builtin `echo' of some bash versions. Reports by Ian Macdonald
1129 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1131 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1133 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1134 separate items of `ac_user_opts', to avoid long lines.
1135 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1137 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1139 * doc/autoconf.texi: Fix some typos.
1141 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1143 Fix some wording problems noted by Paolo Bonzini in:
1144 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1145 * doc/autoconf.texi (Signed Overflow Examples): Give more
1146 discussion about the allow_superuser_privileges example,
1147 and change it a bit to make things clearer.
1148 (Optimization and Wraparound): Clarify whether the compiler
1149 will generate an infinite loop for the example derived from
1150 Autoconf's mktime test.
1151 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1152 Also, clarify unsigned multiplication overflow.
1154 2007-01-04 Eric Blake <ebb9@byu.net>
1156 * bin/Makefile.am (RELEASE_YEAR): New macro.
1157 (edit): Use it to supply correct copyright year to scripts.
1158 * bin/autoconf.as (version): Use it.
1159 * bin/autoheader.in ($version): Likewise.
1160 * bin/autom4te.in ($version): Likewise.
1161 * bin/autoreconf.in ($version): Likewise.
1162 * bin/autoscan.in ($version): Likewise.
1163 * bin/autoupdate.in ($version): Likewise.
1164 * bin/ifnames.in ($version): Likewise.
1166 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1168 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1169 feedback. The most important changes document what happens when
1170 you convert an out-of-range value to a signed integer type, and
1171 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1174 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1175 rewrite, taking notions from the recent discussion on the gcc and
1176 autoconf mailing lists; please see
1177 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1178 and follow the many links.
1179 (Integer Overflow Basics, Signed Overflow Examples):
1180 (Optimization and Wraparound, Signed Overflow Advice):
1181 (Signed Integer Division): New sections.
1183 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1185 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1186 preprocessor macro arguments in traced name.
1187 * doc/autoconf.texi (Defining symbols): Document longstanding
1188 support for AC_DEFINE-ing macros with arguments, and document
1189 behavior when the same variable has multiple AC_DEFINEs.
1190 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1191 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1192 macros directly, giving much shorter and simpler code.
1194 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1196 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1197 space before "$ac_configure_args" to prevent a 'config.status
1198 --recheck' failure if ac_configure_args doesn't contain a leading
1199 space. This works around a problem with the XEmacs configure.ac,
1200 which uses the (undocumented) ac_configure_args variable
1201 inconsistently with Autoconf.
1203 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1205 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1206 Include <limits.h>, and use its INT_MAX to rewrite the
1207 j loop so that it does not overflow 'int'. Problem reported by
1209 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1210 Play it safe by shifting left by 1 rather than multiplying by 2,
1211 as GCC is less likely to optimize this away when the value
1212 is signed (when it assumes overflow leads to undefined behavior).
1213 Also, don't assume time_t uses two's complement.
1215 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1217 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1218 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1219 dumps core on it. Report by Tim Rice.
1221 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1223 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1224 --disable-option-checking to --help output even when
1225 AC_PRESERVE_HELP_ORDER is not used.
1226 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1227 --with argument, rather than argument with [-.] replaced by
1229 * NEWS: Fix typo in previous change; the news was in the
1232 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1234 * NEWS: Warnings are now generated by default for unknown
1235 --enable-* and --with-* options.
1236 * doc/autoconf.texi (Option Checking): Renamed from
1237 (Configure Option Checking). Tighten up the wording a bit.
1238 (External Software, Package Options): Cross-reference to Option
1239 Checking, and use this to shorten our section.
1240 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1241 "$x" to test "x$foo" != x.
1242 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1243 Don't warn if $enable_option_checking is "no".
1244 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1245 ac_unrecognized_opts to the empty string.
1246 Don't echo the unrecognized opts, as this might mishandle
1247 backslashes or leading -.
1248 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1249 usage next to the other --disable-FEATURE options in the
1252 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1254 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1255 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1256 Print warning for unrecognized --with and --enable options
1257 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1258 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1259 Disable option checking when subdirs are configured.
1260 (AC_OUTPUT): If warnings are enabled, print warning about
1261 unrecognized --with and --enable options at the end of
1262 the configure output (as well as at the beginning).
1263 * doc/autoconf.texi (Option Checking): New node.
1264 Document new option warning functionality.
1266 2006-12-16 Eric Blake <ebb9@byu.net>
1268 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1269 * NEWS: Start news for current version.
1271 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1273 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1274 Define HAVE_GETMNTENT to 1, not to the empty string.
1275 Problem originally reported by Jochen Friedrich in
1276 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1278 This change prompted by a problem report by Andrey Simonenko in
1279 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1280 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1281 object-like macros only, in the traditional portable character
1283 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1284 Warn about attempts to define things that are not identifiers.
1285 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1286 awful hack that AC_DEFINEd macro names containing parentheses.
1288 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1290 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1291 too drastic, even if Texinfo in theory requires it for info mode.
1293 (config.status Invocation): Renamed back from Recreating a
1295 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1296 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1298 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1300 * NEWS: Version 2.61a.
1302 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1303 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1305 * NEWS: Document changes with echo and printf, and the lack
1306 of limits on the total size of multi-line values of substituted
1307 variables, and the AC_FUNC_FSEEKO fix.
1309 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1311 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1312 Writing configure.ac.
1313 (Autoconf Input Layout): Renamed from configure.ac Layout.
1314 (Recreating a Configuration): Renamed from config.status Invocation.
1315 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1316 (acconfig Header): Renamed from acconfig.h.
1317 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1318 (Writing Testsuites): Renamed from Writing testsuite.at.
1319 (Autom4te Cache): Renamed from autom4te.cache.
1321 * BUGS: Remove mention of VPATH problem, since it's now documented
1322 not to be a bug in the Autoconf build procedure itself, but rather
1323 a problem with the proprietary `make' programs.
1325 * doc/autoconf.texi (Build Directories): Add a cross reference
1328 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1329 * doc/standards.texi: Sync from gnulib.
1331 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1332 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1333 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1334 generated automatically.
1336 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1338 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1339 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1340 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1342 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1345 `CEOF$ac_eof' special marker, the awk script cannot contain a
1346 line matching `^CEOF', so this is not needed any more.
1347 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1348 special marker in the test.
1350 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1352 * tests/tools.at (autom4te preselections): Use `find -newer';
1353 remove one of the sleeps.
1355 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1356 more readable, using ...
1357 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1359 * doc/autoconf.texi (autoheader Invocation): Do not double-
1360 quote the parameter of `AH_BOTTOM' in the example.
1362 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1364 * doc/autoconf.texi (Configuration Headers): Remove the
1365 example with multiple input files.
1366 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1367 multiple input files.
1369 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1372 creating the awk substitution script, handle one input line at a
1373 time, so that the maximum length of a substituted (multi-line)
1374 value is not limited by the size of the sed pattern space.
1375 The trade-off is a slightly repetitive sed script.
1376 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1377 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1378 * tests/torture.at (Substitute a 2000-byte string): Increase the
1379 test with several long lines, they should not be caught by sed
1382 * tests/tools.at (autom4te preselections): New test, to flag
1383 entries missing from autom4te.cfg.
1384 Report by David Byron <dbyron@hheld.com>.
1386 * tests/torture.at (Substitute a 2000-byte string): Actually use
1387 AC_PROG_AWK, so the last change works as intended.
1388 (Substitute and define special characters): Likewise.
1389 (Substitute a newline): Likewise.
1391 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1392 instead of `awk' consistently.
1393 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1394 * tests/torture.at (Torturing config.status): Test both the
1395 result of AC_PROG_AWK and plain awk.
1396 (Substitute a 2000-byte string): Likewise.
1397 (Substitute and define special characters): Likewise.
1398 (Substitute a newline): Likewise.
1400 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1402 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1403 can be assigned to a function pointer. Problem reported by
1404 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1405 part of a patch by Ralf Wildenhues in that same bug report.
1407 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1409 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1410 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1412 2006-12-01 Eric Blake <ebb9@byu.net>
1414 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1415 cross-compiling from cygwin to mingw.
1416 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1417 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1418 to lib/autoconf/c.m4.
1420 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1422 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1423 string for more reliable failure. Wrap the entire test that
1424 causes the broken Solaris printf to dump core, in a subshell,
1425 so the segmentation fault message is reliably suppressed.
1426 Fix shell expansion errors by using /usr/ucb/echo always;
1427 avoid an error on systems without it by another subshell.
1428 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1429 subshell-$as_echo to `as_echo', for better error message.
1431 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1433 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1434 `BASH_SOURCE' contain a newline, set them to empty, as they may
1437 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1439 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1440 years and is too hard to maintain now. The last straw was
1441 reported by Jerker Baeck in
1442 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1443 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1444 * doc/autoconf.texi (Particular Functions): Move
1445 AC_FUNC_SETVBUF_REVERSED from here...
1446 (Obsolete Macros): ... to here. Say that it does nothing now.
1447 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1448 Turn into (almost) a no-op.
1450 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1452 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1453 These macros are obsolescent and new applications shouldn't need them.
1454 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1455 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1456 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1457 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1458 (AC_FUNC_VPRINTF): Likewise.
1459 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1460 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1461 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1463 * doc/autoconf.texi (Setting Output Variables): Mention that
1464 @VAR1@VAR2 has unspecified behavior. Problem reported by
1466 * NEWS: Mention this.
1468 * Makefile.am: Put only a single '#' into the copyright notice,
1469 so that it's also present in the output file. Standardize wording
1470 in makefile copyright notices to match GNU coding standards.
1471 * bin/Makefile.am: Likewise.

1479 * man/Makefile.am: Likewise.
1480 * tests/Makefile.am: Likewise.
1481 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1484 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1486 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1487 in the sed script that mangles the awk script: delete up to the
1488 first exclamation mark only.
1489 * tests/torture.at (Substitute and define special characters):
1492 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1494 Rewrite config files generation: avoid quadratic growth in
1495 the number of substituted variables by using awk instead of sed
1496 for the bulk of the substitutions.
1497 * NEWS: Mention this.
1498 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1499 forbidden in the output (and thus input) file.
1500 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1501 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1502 generate just one large awk script for substitutions,
1503 eliminating much of the earlier complexity, while adding some
1504 new complexity. Only expand the substitution templates at
1505 configure time, for smaller configure script size. If
1506 _AC_SUBST_FILES are used, test 'awk' for working getline support
1507 at config.status time. If absent, interpolate through the
1508 shell. The awk script was written with much help
1509 from Paolo Bonzini and Paul Eggert.
1510 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1511 (_AC_SED_FRAG_NUM): Likewise.
1512 (_AC_SUBST_CMDS): Renamed from...
1513 (_AC_SED_CMDS): ...this.
1514 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1515 * tests/torture.at (Substitute a 2000-byte string): Also
1516 substitute a line with 1000 words, and a variable with several
1518 (Substitute and define special characters): Test awk special
1519 characters, and put substitution input strings `@foo@' in the
1520 output, to test that no recursion happens; test several other
1521 combinations from Paolo Bonzini.
1523 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1525 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1526 that replaced echo with AS_ECHO where this wasn't necessary.
1527 Problem reportd by Ralf Wildenhues.
1528 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1529 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1530 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1532 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1534 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1536 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1538 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1539 that traditional Awk lacks 3-arg "split". It has it.
1540 Mention that FS must be a single character, and a few other
1541 99-byte limits of traditional Awk.
1542 Mention that if (i in a) doesn't work with traditional Awk.

1546 * tests/autotest.at (BSx641-newline in command):

1548 (Newline-CODE-BS-newline in command):
1549 (Single-quote-BS-newline in command):
1550 (Single-quote-newline-BS-newline in command):
1551 Use printf '%s\n' instead of echo, for portability to hosts
1552 where echo interprets backslashes. This will break on hosts
1553 that lack printf, but for now let's assume all such hosts
1554 are dead (if not, we should get reports of test failures).
1556 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1558 'echo' has some portability problems, when given a first argument
1559 with a leading '-', or when given any argument containing '\'.
1560 Avoid using 'echo' in these cases.

1585 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1586 * bin/autoconf.as: Redo verbose flag implementation, as the old
1587 scheme wouldn't work with AS_ECHO.
1588 * lib/autotest/general.m4 (AT_INIT): Likewise.
1589 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1590 Don't use ECHO_T, since ECHO_N is now reliable.
1591 * lib/autotest/general.m4 (AT_INIT): Likewise.
1592 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1593 rather than using a here-document to put the script into a file.

1597 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1598 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

1601 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
1602 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1603 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1604 operand, as AS_ECHO requires. Avoid double file name expansion.
1605 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1606 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1607 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1608 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1609 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1610 Double-quote strings that would otherwise contain M4 comments.
1611 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1613 * configure.ac (AC_INIT): Bump to 2.61a.
1616 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1620 * configure.ac (AC_INIT): Bump to 2.61.
1623 * tests/autotest.at (Macro with backslash in a test title):
1624 Comment out for now, as this tests neither fails nor passes
1625 reliably. Problem reported by Ralf Wildenhues.
1627 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1629 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

1709 and Paul Eggert <eggert@cs.ucla.edu>
1711 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
1712 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
1715 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1717 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
1718 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
1719 Imported from a similar patch to gnulib by Bruno Haible.
1721 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

1740 and Stepan Kasal <kasal@ucw.cz>
1742 Handle special characters in test case titles correctly.

1745 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1746 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1747 argument. Extend to check titles printed by ./micro-suite and

1750 Single-quote in a test title,
1751 Double-quote in a test title): Don't expect failure anymore.
1752 (Backslash in a test title): Put a non-whitespace character after the
1753 backslash so that Bourne shells might actually see it as an escape
1755 (Brackets in a test title,
1756 Pound in a test title,

1763 Macro with backslash in a test title): New tests expected to fail.
1764 * tests/torture.at (#define header templates): M4-quote this title in
1765 AT_SETUP call so that no M4 code is commented inadvertently somewhere.

1768 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1770 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1771 `trap ... 0' inside a function, for AIX sh.
1773 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1775 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1776 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1777 5363) simply issues a warning when dividing by zero at compile
1778 time. Problem reported by Elias Pipping.
1780 2006-10-26 Eric Blake <ebb9@byu.net>
1783 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1784 show effect on macros that expand with commas.

1809 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1811 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1812 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1813 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1814 reported by Nelson H. F. Beebe for Coreutils 6.4.
1816 * tests/tools.at (autoconf --trace: user macros): Remove test
1817 for tracing multiline macros, since m4 1.4.7a uses a different
1818 way to number lines. Problem reported by Ralf Wildenhues.

1894 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1896 (Imported from Automake.)
1897 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1898 which incorrectly sets the mode of an existing destination
1899 directory. In some cases the unpatched install-sh could do the
1900 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1901 system. We hope this is rare in practice, but it's clearly worth
1902 fixing. Problem reported by Alex Unleashed in
1903 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1904 Also, don't bother to check for -m bugs unless we're using -m;
1905 suggested by Stepan Kasal.

1954 added to the template can get mangled.
1956 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1958 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1959 include the default headers, and redefine obstack_chunk_alloc

1984 Use a better substitute, by inspecting the output of "ls"
1985 rather than just using ":".
1986 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1987 rather than AS_EXECUTABLE_P, since we needn't worry about
1988 non-regular files here.
1990 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1991 due to configuration hassles with this. See Tonya Underwood's report
1992 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

2003 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the

2018 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2019 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2020 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2022 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2023 with werror_flag and conftest.err and so forth. This is more
2024 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2025 and anyway the user shouldn't normally want to see this gorp logged.
2026 Problem reported by Ralf Wildenhues.
2027 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2028 empty, not 'no', since the rest of the code uses 'test -z'.

2032 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

2036 Problem reported by mwoehlke in
2037 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2039 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2040 than creating a file to use with test -x; this is much faster.

2062 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2063 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

2073 Use a nonempty format string in the link test.
2074 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2075 for a declaration of wait3.

2179 7.1.4 /usr/bin/posix/sh described by Tim Rice in

2299 broken lex libraries like native ia64-hp-hpux11.22; see
2300 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

2454 problems with arg script text that doesn't end in newline, and

2491 less skeptical about "volatile", after discussion with
2492 Bruno Haible on bug-gnulib.

2494 leading white space from text. From Bruno Haible.
2496 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2498 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2499 compiler complains about it, even if things works after the
2500 complaint. Problem reported by Peter O'Gorman.
2502 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2503 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

2506 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2508 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

2520 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2521 under AC_C_VOLATILE.
2522 (Volatile Objects): Be a little less skeptical about what
2523 "volatile" means. Derived from thoughts by Ben Pfaff in
2524 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

2532 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2533 more globally, since the 2006-06-30 patch didn't suffice. Problem
2534 reported by Keith Marshall. Also, don't bother with builddir2,
2535 since it shouldn't be needed any more.
2537 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

2556 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2558 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2559 Require that long long int be at least 64 bits wide. C99 requires
2560 this and enough programs depend on it so we should check for it.
2561 Bruno Haible reports in
2562 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2563 that long long int is 32 bits wide with some nonstandard compilers.

2566 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2568 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2569 to a nonexistent file, so that we don't have to worry about
2570 a local site configuration that doesn't use /usr/local.
2571 Problem reported by Keith Marshall in

2574 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2576 * doc/autoconf.texi: Be more consistent about using @acronym with
2577 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2578 quite right (it talked about "OSF/Tru64", even though the
2579 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2580 and it even mentioned "OSF 4"!) and at this point there's little
2581 reason to talk about OSF any more, since it died in 1994.
2582 (Specific Compiler Characteristics): Simplify example of
2583 negative-size array.
2584 (File Descriptors): Reorder to make the text flow better.
2585 Remove joke about "appreciate the various levels"; I didn't get it.
2586 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2587 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2588 (File Descriptors, Limitations of Usual Tools):
2589 Tone down the advice against renaming or removing open files.
2590 (Limitations of Usual Tools): Add a new section, on 'rm'.
2592 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2594 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2595 -lXt in LIBS, idea from Karsten Hopp; this was due since
2598 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2599 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2600 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2601 (which belong to Xt, not X itself). See Debian bug 327655.
2603 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2605 * configure.ac (AC_INIT): Bump to 2.60a.

2628 to document the whole `datarootdir' business a bit better.
2630 * tests/torture.at (datarootdir workaround): Extend test.
2631 Prompted by report by Alexandre Julliard.
2633 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2635 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2636 when using default mode of IBM C 6 for AIX. Problem and two-line
2637 fix reported by Larry Jones.
2639 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2642 about literal '${datarootdir}' if a definition is found in the
2645 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2647 * NEWS: Use "M4" rather than "m4" when appropriate.
2648 Problem reported by Eric Blake.
2649 * doc/autoconf.texi: Likewise.
2650 Use @acronym around BSD, GCC, and GNU when appropriate.
2651 (Why GNU M4): Renamed from "Why GNU m4".
2652 (Redefined M4 Macros): Mention that Posix
2653 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2654 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2657 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2659 * bin/autom4te.in (handle_output): Do not forbid the empty
2661 * tests/tools.at (autoconf: the empty token): New test.
2663 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2665 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2666 calls, so that we do not care whether they are LIFO or FIFO;
2667 in the m4_wrap, do not check which diversion is the topmost
2668 one, just check that the stack is balanced at the end.
2669 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2670 base diversion forever--pop the previous diversion before
2671 opening the new one; consequently, remove the m4_wrap call.
2672 * lib/autotest/general.m4 (AT_INIT): Likewise.
2673 * tests/m4sugar.at: Do not use
2674 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

2677 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2679 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2680 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2681 Rework example of m4wrap token-pasting trouble so that it doesn't
2682 care whether it's LIFO or FIFO.
2683 Fix some "contrary to"s that are awkward in English.
2685 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2687 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2688 to `yes' instead of `int$1_t' if the type is found, for more
2689 consistent configure output (where $1 is the number of bits).
2690 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2691 Suggested by Bruno Haible.
2693 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2694 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2695 with system headers. Report by Bruno Haible.
2697 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2699 * config/config.guess, config/config.sub: Sync from upstream.
2701 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2702 in order to avoid picking up an older installed frozen m4sh.m4f.
2703 Besides an outdated shell startup, this could have been created
2704 by an earlier M4 version with incompatible frozen file format.
2706 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2708 * README: Recommend m4 1.4.4 instead of 1.4.3..
2709 * doc/autoconf.texi: Likewise.
2710 (Special Chars in Names): Say that $(.FOO) is portable, as
2711 suggested by Stepan Kasal.
2712 (Installation Directory Variables, Build Directories):
2713 (Automatic Remaking, Subdirectories, Fortran Compiler):
2714 (Making testsuite Scripts, Defining Directories):
2715 Quote variable usages better.
2716 (Making testsuite Scripts): Add clean-local rule to makefile
2717 snippet, by Eric Blake.
2718 (Installation Directory Variables): Fix table item font.
2719 Reword slightly to clarify. Generalize advice about
2720 not using special characters to include all file-related
2721 vars, not just VPATH.
2722 (Special Chars in Variables): Warn about special characters in
2724 (Assignments): Clarify default-value example as suggested by
2726 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2727 (Special Shell Variables): Note leading ./ or ../, as suggested
2729 (Limitations of Builtins): Under cd, warn about CDPATH.
2730 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2733 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2735 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2736 `@var', for texi2html.
2737 (Systemology): Some more word wrapping, for DVI output.
2738 (autom4te Invocation): The short option for `--melt' is `-M',
2741 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2743 * doc/autoconf.texi: More formatting and English tweaks,
2744 many suggested by Ralf Wildenhues.
2745 Reword to avoid "@code{...}'s" and the like, since it's ugly
2746 with Emacs info mode. discontents -> woes.
2747 Put a few "will"s back. time stamp -> timestamp.
2748 side-effect -> side effect.
2750 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2752 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2753 Warn about $@ not persisting. Problem reported by Julien Danjou in
2754 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2755 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2756 Mention other special chars, too.
2758 2006-06-14 Eric Blake <ebb9@byu.net>
2760 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2762 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2764 * doc/autoconf.texi: Some systematic minor improvements, as
2765 follows. Use "makefile" when talking about makefiles
2766 generally (which might be named "makefile" or "Makefile" or even
2767 "foo.mk"), "Makefile" when talking about a specific makefile
2768 called "Makefile". This unclutters the text from weird quotes
2769 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2770 values" rather than "@var{foo}s" and similar constructs containing
2771 "}s". Use "Make rules" rather than "Makefile rules". Minor
2772 English-language improvements. Change the prefix "sub-" to "sub"
2774 Put blank lines around examples more consistently.
2775 Avoid "rather" and "very" as intensifiers.
2776 Avoid "will" as an auxiliary.
2777 (Limitations of Make): Split this node into....
2778 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2779 (Leading _ in Macro Names, Backslash-Newline-Newline):
2780 (Backslash-Newline Comments, Long Lines in Makefiles):
2781 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2782 (obj/ and Make, make -k Status, VPATH and Make):
2783 (VPATH and Double-colon, $< in Explicit Rules):
2784 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2785 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2786 New nodes, resulting from splitup of Limitations of Make.
2787 All cross-references changed. Raise the top node from
2788 a section to a chapter, and all subnodes accordingly.
2789 Redo the introductory wording to match the new organization.
2790 (Installation Directory Variables): Use an example that is
2791 closer to what Autoconf actually does. Mention that VPATH's
2792 value should not contain metacharacters or white space.
2793 (Fortran Compiler): Fix a VPATH bug in an example.
2794 (Leading _ in Macro Names): Mention that this problem is no longer
2795 of practical concern.
2796 (VPATH and Make): Reword the advice to make it clearer
2797 that Autoconf and Automake support VPATH in non-GNU make, but
2798 many packages have bugs in this area.
2799 ($< in Explicit Rules): Refer to Build Directories rather
2800 than using a (non-VPATH-safe) example.
2801 (Automatic Rule Rewriting): Mention the sort of disaster that
2802 can ensue with Solaris-style rule rewriting with VPATH.
2804 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2806 * doc/install.texi (Compilers and Options): Weaken the
2807 suggestion to use GNU make for VPATH builds.
2809 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2810 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2812 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2813 in regular expression.
2815 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2817 * doc/autoconf.texi (Installation Directory Variables):
2818 Drop extra @samp from `@table @samp' item.
2819 (Limitations of Usual Tools): Comment fix.
2820 Do not nest @samp just to point to other table items.
2821 (Writing testsuite.at) <AT_CHECK>: The second argument to
2822 `@dvar' is already @samp'ed.
2823 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2824 do not use @var in the second argument.
2826 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2828 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2829 $as_shell.exe too. Problem reported by Andreas Buening in
2830 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.

2834 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2835 `unused variable' compiler warning, for `-Wall -Werror'.
2836 Reported by Jaap Haitsma in
2837 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2839 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2841 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2842 case the compiler dumps core. Problem reported for
2843 OpenServer 5.0.7 by Tim Rice in
2844 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2845 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2848 2006-06-06 Tim Rice <tim@multitalents.net>.
2850 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2851 "ERROR" only shows up in "make check" output if there is an
2854 2006-06-06 Eric Blake <ebb9@byu.net>
2856 * tests/tools.at (automatically allowed tokens): Fix typo.
2858 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2860 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2862 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1

2868 * configure.ac (AC_INIT): Bump to 2.59e.
2871 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2875 * config/texinfo.tex: Sync from upstream.
2877 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2878 seen, invoke libtoolize with `--ltdl' argument.
2879 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2881 Suggested by Eric Blake.
2883 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2885 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

2911 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2913 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2914 information about race-free implementations of mkdir.
2916 2006-06-04 Eric Blake <ebb9@byu.net>
2918 * bin/autoreconf.in (help): Document M4 environment variable.
2919 * bin/autoconf.as (Usage): Likewise.
2920 * bin/autom4te.in (help): Likewise.
2921 * doc/autoconf.texi (autom4te Invocation): Likewise.
2923 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2925 * NEWS: GNU make now recommended for VPATH builds.
2926 Mention that some macros are now documented to be obsolescent.
2927 * doc/autoconf.texi:
2928 Prefer "current" to "modern" to describe
2929 currently-used (albeit perhaps old-fashioned) hosts.
2930 Mention which ancient features no longer need to be worried about.
2931 setgid -> set-group-ID
2932 setuid -> set-user-ID (these are the Posix terms)
2933 Fix some misuses of "only".
2934 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2935 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2936 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2937 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2938 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2939 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

2941 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2942 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2943 Mention that these macros are obsolescent.
2944 (Installation Directory Variables): shall -> should
2945 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2946 Mention that it's now safe to use 3 and 4.
2947 (Limitations of Usual Tools): cp -r is now specified by Posix.
2948 Omit longwinded and obsolescent discussion of cp -f.
2949 Modernize discussion of expr, ls.
2950 (Limitations of Make): Modernize discussion of VPATH builds.
2951 Mention $? as a workaround in some cases.
2952 * doc/install.texi (Basic Installation):
2953 Mention "./configure; make; make install" first. Be more
2954 specific about why this file is generic. Remove unnecessary
2955 parens. Remove misleading "only". Remove obsolete advice
2956 about csh. Don't say "configure" takes awhile; say it
2957 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2958 and CC=c99 rather than CC=c89, as these are blessed by current
2959 Posix. Recommend GNU make if doing a VPATH build.
2961 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2963 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2964 examples involving shell prompts.
2966 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2967 and Paul Eggert <eggert@cs.ucla.edu>
2969 * doc/autoconf.texi (Here-Documents): Add details about the
2970 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2971 use "here-documents" instead of "here documents".
2973 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2975 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2977 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2979 * doc/autoconf.texi (File System Conventions): Warn about ":"
2980 anywhere in directory names.
2982 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2984 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2985 about quoting the case statement, just in case.
2986 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2987 was fixed in ksh93g; reported by Ralf Wildenhues.
2989 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2991 * doc/autoconf.texi (System Services): Do not document
2992 overriding EXEEXT via ac_cv_exeext=ext.
2993 (Particular Programs) <AC_PROG_MKDIR_P>:
2994 Document that ${MKDIR_P} understands --.
2995 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2998 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3000 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3001 argument with leading hyphen. Problem reported by Paul Eggert.
3003 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3005 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3006 about quoting ac_try: quote all of it, if any of it seems suspicious.
3007 This means we don't have to worry about ${ or sed any more.
3008 Also, double-quote the case statement, to work around misuses via
3009 underquoting as reported by Ralf Wildenhues in
3010 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3011 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3012 undocumented and dangerous macro.
3013 Problem reported by Ralf Wildenhues in
3014 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3016 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3018 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3019 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3020 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3022 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3024 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3025 since evidently some packages rely on the old, broken behavior.
3026 Problem reported by Ralf Wildenhues in
3027 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3028 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3029 pre-2006-05-26 definitions, but leave in the comments that
3030 these macros are dangerous and should not be used.
3031 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3032 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3033 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3034 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3035 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3037 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3039 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3040 the use of 'tr', since this is our only use of 'tr'.
3042 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3043 and Paul Eggert <eggert@cs.ucla.edu>
3045 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3046 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3048 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3050 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3051 the output file in the `${datarootdir}' test.
3053 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3054 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3056 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3057 mention of `datarootdir' in the input file(s), but literal
3058 `${datarootdir}' in the output file, and we haven't warned yet,
3059 then warn as well: the user may have (erroneously) used
3060 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3061 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3062 * tests/torture.at (datarootdir workaround): Extend this test.
3065 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3066 and Paul Eggert <eggert@cs.ucla.edu>
3068 * doc/autoconf.texi (autoheader Invocation): The first argument to
3069 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3070 alternatives and clear up the language a bit.
3072 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3074 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3075 ac_config_guess, ac_config_sub, ac_configure.
3076 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3077 Fix typo that prevented an unnecessary space from being removed.
3078 Problems reported by Ralf Wildenhues in:
3079 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3081 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3083 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3084 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3085 Don't use the term "thread-safe" to talk about mkdir race
3086 conditions, since the problem is more a process than a thread
3087 issue. Problem reported by Stepan Kasal in:
3088 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3089 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3090 the test for 'install' more closely. Look at MKDIR_P first.
3091 Look in the PATH, and at /opt/sfw/bin.
3092 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3093 Don't bother to try mkdir -p, since we already check mkdir --version;
3094 just look at the version number. (There's no easy way to check
3095 for race-free implementations.)
3096 * tests/tools.at (autoconf: subdirectories): Adjust to above
3097 changes, since MKDIR_P now might end in "/mkdir -p".
3099 * doc/autoconf.texi (autoheader Invocation): Mention that the
3100 first arg of AC_DEFINE_UNQUOTED must be a literal.
3101 Problem reported by Ben Pfaff in
3102 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3104 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3105 * doc/autoconf.texi (Special Chars in Variables): New section.
3106 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3107 (Installation Directory Variables): Quote $(datadir) better.
3108 (Limitations of Builtins): Describe some of eval's trickiness.
3110 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3111 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3112 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3113 in front of every arg, not just trailing args. Quote apostrophes.
3114 (_AC_EVAL_ECHO): New macro.
3115 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3116 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3118 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3119 exposed by quoting of eval argument. Put the command on line line
3121 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3122 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3123 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3124 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3125 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3126 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3127 Use eval more safely.
3128 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3129 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3131 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3132 lines, exposed by quoting of eval argument.
3134 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3135 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3137 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3138 initialization of `ac_cv_exeext', do not override it if it was
3139 already set, unless it was set to `no', for compatibility with
3140 Autoconf-2.13, and comment this.
3141 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3142 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3143 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3144 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3145 Document that this test may be overridden by setting
3148 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3150 Revert these two patches:
3152 2006-04-06 Eric Blake <ebb9@byu.net>
3153 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3154 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3157 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3158 Clean up _AC_COMPILER_EXEEXT* macros.
3159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3160 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3161 ac_file to the name of the default output file and call
3162 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3163 initial `rm' of the candidate files...
3164 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3165 the same list in subsequent `rm' calls, and for the temporary
3166 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3167 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3168 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3169 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3170 no longer needed) by libtool. Make it a cache check.
3171 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3172 copied here by mistake.
3173 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3174 _AC_COMPILER_EXEEXT.
3175 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3176 _AC_COMPILER_OBJEXT directly.
3177 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3179 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3181 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3182 Fix description of how the buggy `sed' works.
3184 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3188 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3189 ENOLCK. Only mention `make -j' when applicable. Only raise
3190 fatal errors when `make -j' is involved. Improve error message.
3192 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3194 * doc/autoconf.texi (Here-Documents): We now know more about
3195 the variable expansion in here documents bug.
3196 Thanks to Tim Rice and Stepan Kasal.
3198 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3199 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3201 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3203 * tests/autotest.at (Multiline command from M4 expansion):
3204 No failure to be expected if the shell quotes newlines in
3205 commands in the `set -x' output. Report by Tim Rice.
3208 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3210 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3211 expansion in the here-documents used by config.status, as that
3212 runs afoul of the Korn shell version M-12/28/93d bug described in
3213 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3214 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3215 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3217 2006-05-23 Jim Meyering <jim@meyering.net>
3219 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3220 Fix typo introduced with 2006-04-02 change. It reversed the sense
3223 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3225 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3226 ac_dB slightly, to save bytes in the script.
3227 Max out at 50 lines, rather than 96; this is more likely
3228 (though not guaranteed) to avoid obscure 'sed' failures.
3230 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3232 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3233 `tr -d -' as bad option argument. Work around this by deleting
3234 an unrelated character.
3235 Report by Tim Rice <tim@multitalents.net>.
3237 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3238 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3239 Stepan Kasal <kasal@ucw.cz>
3241 * doc/autoconf.texi (Particular Programs): Do not promise that
3242 we always prefer the GNU version of the program, and that we
3243 search according to PATH; both rules can have exceptions.
3244 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3245 AC_PROG_SED. Move descriptions of limitations
3246 to the Limitations of Usual Tools section.
3247 (Limitations of Usual Tools) <sed>: Mention script length
3248 limitations with Solaris /usr/ucb/sed.
3249 <grep>: Fix wording for empty alternative. Mention that -c and
3250 -l should not be combined, and that -E and -F should not be
3253 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3256 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3257 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3259 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3261 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3262 AC_DEFINE is now passed to m4_pattern_allow.
3263 * NEWS: Mention that; likewise for AC_SUBST.
3264 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3265 the parameter to m4_pattern_allow.
3266 * tests/tools.at: Add a check for that.
3268 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3270 * lib/autoconf/status.m4: Fix typos.
3272 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3274 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3275 only the files that this macro generates.
3277 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3279 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3280 the HP-UX sed limitation of 99 commands, labels do not count.
3281 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3283 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3285 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3287 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3288 Import the following fix from coreutils:
3290 2006-01-13 Jim Meyering <jim@meyering.net>
3292 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3293 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3294 not double-quote uses of that variable, to accommodate the rare
3295 case in which getmntent is available in none of the libraries
3296 checked. This happens at least on FreeBSD 5.0.
3298 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3300 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3301 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3302 some other programs unwisely rely on these undocumented vars.
3303 But put in warning comments about them.
3304 Problem reported by Ralf Wildenhues in
3305 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3306 * NEWS: Document that these variables are intended to go away.
3308 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3310 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3311 and set the language to C++ (analogous to the equivalent Fortran
3314 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3315 * doc/autoconf.texi (C++ Compiler): Document it.
3316 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3319 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3321 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3322 that caused config.status to generate 100-command sed scripts; the
3323 portable limit is 99.
3325 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3327 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3328 variable `ac_d' instead of `d' to avoid infringing namespace.
3329 Report by Ralf Menzel.
3331 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3333 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3334 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3335 * tests/tools.at (autoconf: subdirectories): New test, taken from
3336 the corresponding problem report by Ralf Wildenhues in:
3337 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3339 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3340 Quote some uses of shell variables if they might suffer unexpected
3341 globbing. This doesn't fix all instances of quoting problems that
3342 I found, just the easy ones that look safe.
3343 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3344 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):

3354 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3356 * bin/autoreconf.in ($help): Reword according to the manual.
3357 Suggested by Olly Betts.
3359 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3360 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3362 * bin/autoreconf.in: Pass the directory argument to
3363 `require_configure_ac'. Fix comment.
3364 * tests/torture.at (Configuring subdirectories): Expose this.
3365 Reported by Olly Betts.
3367 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3369 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3370 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3371 Automake as follows:
3373 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3374 `$configure_in' instead of `configure.in', to preserve
3375 directory component.
3377 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3379 * config/config.guess, config/config.sub, config/texinfo.tex,
3380 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3382 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3384 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3385 test for C99 conformance; (bool) 0.5 is an integer constant
3386 expression, but (bool) -0.5 is not. Problem reported by Fedor
3387 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3389 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3391 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3392 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3393 Warn about obsolete install-sh files. Remove stray sentence
3394 fragment and fix cross reference.
3395 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3396 install -d; this undoes the 2006-05-10 change.
3397 (MKDIR_P): Mark with AN_MAKEVAR.
3398 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3399 that we don't require $INSTALL to be thread-safe. Move comments
3400 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3401 of AC_PROG_INSTALL. Output a message saying that we're checking
3402 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3403 MKDIR_P instead of AC_SUBST.
3404 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3405 Special magic for MKDIR_P, too.
3406 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3408 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3410 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3412 Sync from Automake, as follows:
3414 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3415 * config/install-sh: Initialize IFS, so field splitting isn't
3417 * config/mkinstalldirs: Likewise.
3418 * config/missing: Remove superfluous quotes. Replace all uses of
3419 `[' by `test', for consistency, and for..
3420 * config/missing (sed_minuso, sed_output): New variables.
3421 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3422 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3423 Fixes `missing' to detect `--output' for help2man. Fixes
3424 PR automake/483. Report by Dennis J. Linse.
3425 (autom4te): Document in `missing --help'.
3427 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3429 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3430 * config/install-sh: Don't use 'path' to talk about file names,
3431 as per GNU coding standards. Close a race condition reported by Ralf
3432 Wildenhues and Stepan Kasal. There is still a race condition
3433 on hosts that predate Posix 1003.1-1992, but we can't help this.
3434 Don't mishandle weird characters like space on pre-Posix hosts.
3435 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3436 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3437 AC_PROG_MKDIR_P from AS_MKDIR_P.
3438 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3439 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3440 earlier editions are not (including Automake 1.8.3).
3441 Do not suggest mkinstalldirs for thread-safety.
3442 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3443 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3444 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3445 presence of special characters and race conditions.
3446 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3447 in Autoconf's name space.
3449 2006-05-10 Bruno Haible <bruno@clisp.org>
3450 and Paul Eggert <eggert@cs.ucla.edu>
3452 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3453 from Automake with minor changes.
3454 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3456 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3458 * config/install-sh: Update to Automake CVS version, as follows:
3459 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3460 * lib/install-sh: Simplify the expr implementation of dirname.
3461 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3462 * lib/install-sh: Handle --, and diagnose unknown options.
3464 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3466 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3467 `./autom4te' to create `./testsuite', since the `all' target
3468 will ensure its presence, but `installcheck' should not create
3469 the uninstalled wrappers.
3471 * tests/torture.at (Unusual Automake input files): Skip if we
3472 detect automake < 1.8.
3474 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3476 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3477 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3478 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3481 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3483 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3484 munge (multiple) white space and other oddities.
3485 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3486 single quotes in variable assignment.
3487 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3488 and similar failures by adding multiple spaces, tabs, and other
3490 Report and different test suggested by Francesco Romani
3491 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3493 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3494 single quotes, we only need to search for single quotes; this
3495 both simplifies the search pattern, and makes us less
3496 susceptible to `echo' variations for arguments not containing
3498 (_AC_ARG_VAR_VALIDATE): Likewise.
3500 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3502 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3503 `$*' and IFS concatenation issue with traditional shells and
3504 bash-2.04. Report by Seanster@Seanster.com.
3506 2006-05-03 Bruno Haible <bruno@clisp.org>
3508 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3509 precisely which Mac OS X versions have the od problem.
3511 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3513 * doc/autoconf.texi: Use @option systematically.
3515 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3516 and Bruno Haible <bruno@clisp.org>
3518 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3520 (Integer Overflow): Mention the special case of integer division
3523 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3525 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3526 traditional shells like the Solaris one that do not use the
3527 first IFS character for assembling `$*'.
3528 Prompted by a related report from autoconf_bug@nro.ca.
3530 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3531 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3533 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3534 Mention more problems with the -e option.
3536 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3539 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3541 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3542 in URLs to improve DVI formatted output (requires texinfo 4.6).
3543 (System Services, Systemology, Shellology): Likewise.
3544 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3547 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3549 (Runtime): Fix macro argument names to match description:
3550 `action-if-found' -> `action-if-true' and similarly.
3551 (Obsolete Macros): Likewise.
3552 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3553 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3554 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3556 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3558 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3561 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3564 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3566 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
3567 /bin/sh set unsorted output.

3574 (Integer Overflow, Null Pointers, Buffer Overruns):
3575 (Floating Point Portability, Exiting Portably): New sections.
3576 (Writing Test Programs): Fix some langauge. Recommend exiting
3577 with status 1, not merely nonzero. Clarify exit declaration.
3578 (Run Time): Move C exit status stuff to new Exiting Portably section.
3579 (Systemology): Mention Posix and levenez. Update v7 reference.
3580 (Portable Shell): Mention the Posix shell.
3582 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3584 * bin/autoconf.as (me): Replace by as_me.
3586 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3588 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3589 since as_me isn't set yet.
3591 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3593 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3594 a few minor bugs in this area.
3596 * doc/autoconf.texi (Programming in M4sh): Comment out the
3597 documentation of AS_BASENAME, for now.
3598 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3599 (Limitations of Builtins) <basename>: Do not refer to
3601 * bin/autoconf.as (me): Don't use AS_BASENAME.
3602 (dir): Remove the unused variable.
3603 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3604 AS_DETECT_REQUIRED. All uses changed.
3605 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.

3611 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3612 (_AS_DIRNAME_PREPARE): Likewise.
3613 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3614 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3615 (AS_DIRNAME): Use "dirname --".
3617 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3619 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3620 of "run time" and "run-time" changed to "runtime", for consistency.
3621 * lib/autoconf/fortran.m4: Likewise (in comment).
3622 * lib/autoconf/functions.m4: Likewise.
3623 * lib/autoconf/general.m4: Likewise.
3624 * lib/autoconf/headers.m4: Likewise.
3626 * doc/autoconf.texi (Run Time): Document the exit status situation
3627 with more accuracy and detail.
3629 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3631 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3632 Archive is not officially `GNU' any more. Update URL.
3633 (Defining Directories): Likewise
3634 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3636 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3638 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3639 newline from the `trap' code to finish `config.log'; the NetBSD
3640 /bin/sh resets the exit status after an empty command, as
3641 documented in doc/autoconf.texi.
3642 Reported by Dalibor Topic <robilad@kaffe.org>.
3644 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3646 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3647 Suggested by Bruno Haible.
3649 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3651 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3652 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3653 Instead, just list the shells that we know work.
3654 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3655 changed. Be more cautious about the _cv_ variable.
3656 * tests/tools.at (Syntax of the shell scripts): Check the
3657 _cv_ variable once, at first, to avoid an internal autoconf error
3658 when sh -n does not work.
3660 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3662 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3664 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3666 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3667 use ">&-" since we're only 99.999% sure that this is portable,
3668 and since the MinGW bug is fixed in a different way.
3669 * lib/autotest/general.m4 (AT_INIT): Likewise.
3671 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3673 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3674 before opening config.log, to avoid hitting a bug on MinGW.
3676 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3678 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3679 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3680 This works around a MinGW bug reported by Eric Paire.
3681 Make sure that all writes to the log file append to it,
3682 rather than possibly losing data.
3683 * lib/autotest/general.m4 (AT_INIT): Likewise.
3685 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3687 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3690 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3694 * configure.ac (AC_INIT): Bump to 2.59d.
3696 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3700 * Makefile.maint (news-date-check): Do not require a leading `*'
3701 before the release date in NEWS.
3703 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3704 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3706 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3707 the instantiated file do not contain the string 'datarootdir'
3708 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3709 @mandir@, replace the reference '${datarootdir}' by the value.
3710 * tests/torture.at (datarootdir workaround): New test.
3711 * NEWS: Advertise this temporary fixup.
3712 Based on a patch by Bruno Haible, reported and analyzed by
3713 Paul Eggert and Noah Misch.
3715 2006-04-12 Eric Blake <ebb9@byu.net>
3717 * tests/autotest.at (Debugging a failed test): Fix comment.
3719 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3721 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3722 all the changes since 2006-04-07.
3724 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3726 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3727 succeeded, but `ln -s file dir' failed, take care to remove the
3728 leftover target before the next test, to prevent its spurious
3729 failure; also make sure `ln file dir' works before selecting it.
3730 Thanks to Keith Marshall for pointing this out.
3733 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3734 assignments in `at_debug_args', so that we put them correctly
3735 in the `run' script.
3736 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3737 Reported by Eric Blake.
3739 2006-04-11 Eric Blake <ebb9@byu.net>
3741 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3742 top-level tests after micro-suite has been run. Used in...
3743 (Debugging a successful test, Debugging script and environment),
3744 (Debugging a failed test): ...these new tests. The first of these
3746 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3747 macro, split out from...
3748 (AT_INIT): ...here, so that using -d also generates a run script.
3749 Document that -d inhibits top-level logging.
3750 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3751 inhibits top-level logging; debug scripts are created.
3753 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3755 * tests/autotest.at (Empty test, Empty check): New test to check it.
3757 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3760 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3762 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3763 the files if a problem appears. Make the empty *.at files
3764 read-only, too. Proposed by Ralf Wildenhues.
3766 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3768 * config/Makefile.am: Add comment to force updated Makefile.in.
3770 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3771 space only patch to this file, this patch causes the Makefile.in
3772 files that include freeze.mk to be updated, and thus have a
3773 newer time stamp again, which in turn makes a pristine CVS
3774 checkout have correct time stamps.
3776 * Makefile.maint (cvs-sv): New macro, to be used..
3777 (config.guess-url_prefix, config.sub-url_prefix)
3778 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3779 point to CVS text checkout of Gnulib files.
3780 (copyright-check): Bump current year.
3781 (announcement): Do not hard-wire `./announce-gen'.
3782 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3784 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3786 (wget_files): Update config.guess, config.sub, texinfo.tex by
3787 `wget-update', now that their URLs work again.
3789 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3791 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3792 Problem noted by Paul D. Smith.
3794 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3796 * doc/autoconf.texi: Remove unused words from word list.
3797 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3798 .x-sc_trailing_space: New files.
3800 * doc/standards.texi: Sync from gnulib.
3802 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3803 `LIBOBJDIR' as experimental.
3805 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3806 with a target directory; it's internally implemented as `cp'
3807 anyway, but since Autoconf advertises the possibility to use
3808 a target directory when LN_S is `ln -s', we need to find out.

3925 _AS_DETECT_BETTER_SHELL:
3927 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

3978 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3980 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3981 whether `set' quotes correctly: redirect stderr of the tested
3982 `set', and use a subshell, for Ultrix; use `sed' instead of
3983 `grep' for zsh `set' which may write binary output; match only
3984 at the beginning of a line, to avoid false positives.
3985 In order to avoid false positives by unrelated variables with
3986 multiline content, put the dump algorithm in a subshell and
3987 unset all variables containing newlines (except some which are
3988 special to the shell). Warn about cache variables that are

4037 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4038 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4039 2005-07-25 rewrite. Noticed by Noah Misch.
4041 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

4192 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4193 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

4195 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4196 initial `rm' of the candidate files...

4981 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4982 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4983 by the function rather than ignoring it.
4984 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4985 comparing its address. Intel's interprocedural optimization was
4986 outsmarting the old heuristic. Problem reported by

5021 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5023 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5024 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5025 (which belong to Xt, not X itself). See Debian bug 327655.
5026 * NEWS: Mention this.

5037 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5039 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5040 calls, so that the final expansion of this macro is shorter.
5041 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5042 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5043 the cleanup there. Use AS_VAR_* macros, to be more general.
5044 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5046 * lib/autoconf/general.m4: Use AS_IF where appropriate.

5073 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5074 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

5094 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5095 Update limitations about when to call AC_CONFIG_HEADERS.
5096 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5097 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5098 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5099 ``Configuration Actions''; fix their index entries.
5101 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5102 options correctly. Process N-M as M-N if M is smaller than N.
5103 Process ranges correctly so that N-N will run only N.
5104 Sort and uniquify the tests that will be run. If there is more
5105 than one test, reinsert the banners for the tests.

5111 before passing the macro name to AH_TEMPLATE.

5134 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5136 When building in place, set srcdir="."; suggested by Tim Van Holder.
5138 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5139 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5140 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5141 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5142 does not mean "no --srcdir option".
5144 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5158 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5160 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5161 was pushdef'ed twice while popped only once. Push it only once.

5176 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5178 Rewrite substantial part of lib/autoconf/status.m4.
5179 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5180 and CONFIG_COMMANDS are not processed in four separate loops.
5181 Instead, there is one main loop. This alows that the common code
5182 is expanded only once, thus config.status (and configure) is smaller.
5184 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5185 the AC_LIST_FILES and cousins macros are no longer used.
5187 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5188 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5189 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5190 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5191 contain the initialization, nor the for loop, nor the associated
5192 commands; all these go to ...
5193 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5194 _AC_OUTPUT_CONFIG_STATUS.
5195 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5196 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5197 (_AC_OUTPUT_FILE): The creation of the sed script ...
5198 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5199 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5200 _AC_OUTPUT_MAIN_LOOP.
5201 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5202 _AC_CONFIG_COMMANDS): Use ...
5203 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5204 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5205 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5206 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5207 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...

5217 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5218 this didn't belong to the `config commands' section.
5219 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5220 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5221 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5222 to the `config commands' section either.

5238 parameter to AC_DIAGNOSE.
5239 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5240 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

5242 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5244 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

5337 sed substitution command, so that we allow | in program prefixes
5338 and program suffixes. (& is a problem anyway; we're not fixing

5341 configure_input, top_builddir, srcdir, etc.
5342 * lib/autotest/general.m4 (AT_INIT): Likewise, for

5353 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

5406 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5407 the directory specific variables; but don't call it for configure_input.

5411 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5414 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

5434 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5435 variable into diagnostic. Make the diagnostic an error, not a warning,
5436 because we really don't support spaces and suchlike in dir names.
5437 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5438 Don't worry about backslashes in srcdir; it can't happen now.

5482 * doc/autoconf.texi:
5483 Don't mention Solaris versions so much, if a
5484 problem is common to all extant versions of Solaris. Say "SunOS
5485 4" instead of "SunOS" for SunOS 4.
5486 (awk): Mention more of the limitations of traditional Awk.

5529 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5530 -u, since it outputs chatter if the input files are the same.
5531 Problem reported by Ralf Menzel.
5533 2005-06-08 Derek Price <derek@ximbiot.com>
5535 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5536 renaming them since they are about to be redefined anyhow.
5538 2005-06-08 Derek Price <derek@ximbiot.com>
5540 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5541 redefined M4 macros to this node. Document m4_include & m4_sinclude.

5547 * doc/autoconf.texi (Introduction): Likewise.
5548 Reword to avoid some formatting glitches.

5551 Redo example output tp match current CVS snapshot.
5552 Use @example.org in email addresses when the examples
5553 might get inadvertently cut-and-pasted into user code.
5554 Remove example of autom4te usage that doesn't seem to work now.
5555 Use modern AC_INIT (except when the example is meant to be

5575 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5577 m4_cdr of one-member list was [[]] (one-member list containing an
5578 empty string) instead of [] (an empty list. Callers were skewed to
5579 match this misbehaviour. As a consequence of this:
5580 - m4_foreach([x], [], [foo]) expanded to `foo', while
5581 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5582 This bug has been fixed:
5584 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5585 expand to an empty string; print error msg if called without
5587 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5588 misbehaviour; handle [] and [[]] correctly.

5598 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5599 swallow records with more than 99 fields.
5600 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5601 parse the long line.
5603 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5605 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5606 swallow literals longer than 399. Reported by Ralf Wildenhues.
5607 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

5640 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5641 now contain newlines, and substituted files must be referenced on

5674 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5676 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5677 messages when ac_unique_file is not found.
5678 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5679 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5680 commands, for consistency with AC_MSG_ERROR and such.

5690 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
5692 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5694 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5695 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5696 (ac_top_builddir): ... this ...
5697 (ac_top_build_prefix): ... to this; the old name is also kept, for
5698 backward compatibility.
5699 (ac_top_builddir_sub): New variable, without the trailing slash,
5701 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

5703 ac_top_builddir to ac_top_build_prefix.
5704 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5705 at_top_builddir to at_top_build_prefix.

5715 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5716 argument to m4_foreach. I guess it was necessary in the past,
5717 but I think it's a no-op now.
5719 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5721 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5722 ``cat <<_ACEOF'' commands to one.
5723 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5724 * lib/autoconf/status.m4: On various places, use expr instead of
5726 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):

5791 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5793 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5794 for absolute directory names in one loop.

5796 abbreviations of --version and --debug.
5798 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5800 * doc/autoconf.texi (Autoconf Language): Be more precise about
5801 quoting rules. Problems noted by Stepan Kasal.
5802 Also, throughout this document, be more careful about white space.
5803 "blank", "white space", and "space" all have different meanings
5804 and we should be careful to say what we mean.
5806 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5808 Fix C++ related problems reported by Werner Lemberg.
5809 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5810 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5811 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5812 avoid problems with C++ and throw.
5813 * tests/compile.at: .cpp, not .cc.
5815 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5817 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5819 * doc/autoconf.texi (Generic Functions): Typos.
5821 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5823 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5824 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5825 set by latest automake.
5827 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5829 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5830 outputs 0 on GNU/Linux these days.
5832 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5834 * doc/autoconf.texi (Autoconf Language): Add more description
5835 about quoting heuristics.
5836 (Limitations of Builtins): Describe "set -" problems.
5838 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5840 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5843 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5844 by AC_DEFINE; it was a mistake.
5845 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5847 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5849 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5851 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5853 * doc/autoconf.texi (External Software): Quadrigraphs are not
5854 processed correctly in AS_HELP_STRING; avoid this in the examples.
5855 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5856 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5857 comment and reduce m4_default([foo], []) to [foo].
5858 (m4_strip): Update the explanation.
5860 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5862 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5863 Remove core.conftest.* too; it's generated by Tru64 5.1.
5864 Problem reported by Jennis Pruett.
5865 * lib/autoconf/functions.m4
5866 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5867 Don't bother to remove core files; AC_RUN_IFELSE should do that
5870 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5872 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

5876 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
5877 Report from Horst Wente.
5879 2005-04-15 Stepan Kasal <kasal@ucw.cz>

5886 * doc/autoconf.texi (External Software, Package Options): Add
5887 examples showing how to implement --with-* and --enable-* options.
5889 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5891 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5892 as well as configure.in. Problem reported by Gregorio Guidi.
5894 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5896 * doc/autoconf.texi (Particular Functions): Use gnulib's current

5909 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5910 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5912 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5914 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5915 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5916 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5917 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5918 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5920 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5922 * NEWS: The configure command now warns you if you attempt to use
5923 a directory whose name contains a special character like space,
5925 * doc/autoconf.texi (Installation Directory Variables): Allow
5926 "," in file names. Do not use \@; it's not a portable regexp.
5927 * bin/Makefile.am (edit): Likewise.
5928 * lib/Makefile.am (edit): Likewise.
5929 * tests/Makefile.am (edit): Likewise.
5930 * tests/semantics.at: Likewise.
5931 * tests/torture.at: Likewise.
5932 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5933 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5934 * doc/autoconf.texi (File System Conventions): Warn about
5935 unportable file names.
5936 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5938 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5939 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5940 ac_pwd, and quote srcdir.
5941 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5943 * doc/autoconf.texi: Fix some systematic formatting problems.
5944 ".)" needs a following @: if not at the end of a sentence, and
5945 similarly for "!)". "etc." should be preceded by a comma.
5946 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5948 2005-03-22 Bruno Haible <bruno@clisp.org>
5950 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5951 argument is often called 'build-aux'.
5953 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5955 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5956 macro AC_TRY_LINK is obsolete.
5957 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5960 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5962 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5963 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5964 from a Common Lisp's `cl'.
5965 (AC_PROG_CXX): Behave according to the documentation: don't
5966 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5967 make the variable CCC precious; use `cl.exe', not `cl'.
5969 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5970 Alexandre Duret-Lutz <adl@gnu.org>
5972 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5973 /dev/null, as "configure" shouldn't read stdin, and this insulates
5974 us from problems (e.g., when testing for "cl"). Also, do this
5975 redirection before invoking "hostname" or "uname", and keep the
5976 original input stream available via...
5977 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5978 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5979 bother with "</dev/null" since it's now done at the top of
5981 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5982 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5983 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5984 * doc/autoconf.texi (File Descriptor Macros): New section.

5988 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5990 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5991 newline if neither \c nor -n work, as that would output two
5992 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5994 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5996 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5997 This causes that any required macros inside will get before the if.
5998 * doc/autoconf.texi (autom4te.cache): A typo.
6000 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6002 Undo previous change, except keep the change to
6003 lib/autoconf/programs.m4 that replaced grep with shell
6004 pattern-matching. This is because net-snmp configure reads stdin.
6005 Reported by Noah Misch.
6007 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6009 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6010 from /dev/null, as "configure" shouldn't read stdin, and this
6011 insulates us from problems (e.g., when testing for "cl").
6012 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6013 before invoking "hostname" or "uname".
6014 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6015 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6016 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6017 "</dev/null" since it's now done at the top of 'configure'.
6018 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6019 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6020 Also, replace grep with shell pattern-matching, to save a process.
6022 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6024 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6025 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6026 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6029 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6031 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6032 grep -q isn't portable. Improve grep -s explanation.
6033 Problem reported by Dan Manthey.
6035 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6037 * doc/autoconf.texi (Special Shell Variables): Clarify
6038 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6040 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6042 * doc/autoconf.texi: Use @acronym for DJGPP.
6043 Fix some @code's that should have been @env's, and vice versa.
6044 Sort environment variable names.
6045 Mention that shells no longer inherit IFS.
6046 Don't recommend PATH_SEPARATOR=';' so strongly.
6047 Mention that $RANDOM might expand to the empty string.
6048 "symlink" and "soft link" -> "symbolic link".
6049 Improve mktemp description (reported by Bruno Haible).
6051 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6053 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6054 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6056 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6059 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6061 * NEWS: Mention AT_COPYRIGHT.
6063 * tests/local.at (AT_CMP): Use diff directly on input files rather
6066 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6067 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6069 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6070 and Paul Eggert <eggert@cs.ucla.edu>
6072 * tests/autotest.at (Empty test suite): New test.
6073 * tests/torture.at (Substitute and define special characters)
6074 (Substitute a 2000-byte string, Define to a 2000-byte string)
6075 (Substitute a newline, Define a newline): New tests.
6077 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6079 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6080 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6081 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6082 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6083 (Standard regular expressions): New test.
6084 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6085 excess test name quoting.
6086 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6087 CPPFLAGS to `configure' instead of setting it in `configure'.
6089 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6090 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6093 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6094 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
6096 * tests/local.at (AT_CMP): New macro.
6097 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

6099 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
6100 (AT_CONFIG_CMP): New macro.
6101 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
6102 * tests/c.at (Extensions): Do not exit early.
6103 * tests/atlocal.in: Inherit $GREP.
6105 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
6106 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
6108 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
6109 (AC_COPYRIGHT): Factor header comment portion out and move into...
6110 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.

6125 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6127 Try not to generated lines of unlimited length, as POSIX places a
6128 2047-byte limit on line length of portable text files.
6129 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6130 Use newline as a separator, not space.

6188 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6189 Update the long comment explaining it.
6191 m4_require no longer writes an ``is required by'' line to the
6192 execution stack. It contains only one bit of non-redundant
6193 information: that the macro was required, not called. And even
6194 this bit is useless in most situations: have you ever met a macro
6195 which both calls and requires the same macro?
6197 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6198 (_m4_defun_pro_outer): ... only via this macro, for the outermost

6205 (_m4_require_call): Use it.
6206 * tests/m4sugar.at (m4_require): Expect output without the
6207 ``is required by'' messages.
6209 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

6243 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6245 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6246 Warn about newline stripping in `` and $(). Update Solaris
6248 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6249 X insulates us from future changes to Posix.
6250 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

6277 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6303 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6304 stored in _m4_divert_diversion or _m4_divert_dump.
6305 (m4_divert_pop): When the parameter is given, compare the symbolic
6306 name with the last diversion pushed on the stack. Previously, the
6307 current diversion was compared with the numeric value of the
6308 diversion given as the parameter.
6309 (m4_require): If the macro hasn't been expanded yet, call ...
6310 (_m4_require_call): this new macro.

6584 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
6585 PATH members so as to not prepend an empty element. Move a comment.
6586 * Makefile.am (SUBDIRS): Build in `tests' last.
6587 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
6589 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
6591 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
6592 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6593 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
6594 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
6596 2004-12-07 Stepan Kasal <kasal@ucw.cz>
6598 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

6609 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
6610 out the common code to ...
6611 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
6612 value of the #define--default to 1, iff the macro was called
6613 with exactly one parameter.
6615 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6617 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6618 "char c = '\200';" rather than "char c = 0x80;" as the
6619 latter doesn't conform to the strict C standard due to
6620 overflow on signed char hosts.
6622 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6623 to -qlanglvl=ansi. We don't want to disable extensions.
6625 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
6627 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
6628 (Using Autotest, testsuite Scripts, Writing testsuite.at):
6629 Reword slightly to avoid some English-language problems noted

6643 Automake (not without Autoconf).
6644 (Introduction): Mention lists.gnu.org.
6645 * BUGS: Don't mention bugs.gnu.org.
6646 Remove mention of ancient libtool compatibility problem.
6647 * NEWS: Mention that bugs.gnu.org is kaput.
6648 * README: Likewise. Mention where mailing list archives can be found.

6670 in my editing of the previous patch. Problem reported
6671 by Alexandre Duret-Lutz.
6673 2004-11-22 Stepan Kasal <kasal@ucw.cz>
6675 * doc/autoconf.texi (Autoconf Language): Explain that
6676 ``descriptions'' may not be double quotes.
6677 (Quotation Rule Of Thumb): Likewise.
6678 (Pretty Help Strings): Likewise; remove the wrong comment;
6679 simplify the examples and improve their quoting.
6681 2004-11-13 Stepan Kasal <kasal@ucw.cz>
6683 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
6684 the $1_found variable, don't test whether the file is executable;
6685 Both things are checked ...
6686 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
6687 the former ``test -f''.
6688 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
6690 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

6695 2004-11-10 Derek R. Price <derek@ximbiot.com>
6697 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
6698 limitations. Reorder paragraphs for clarity.
6700 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
6702 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
6703 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
6704 variants", "Unix", and some related minor wording fixups.
6706 (Shellology, Special Shell Variables): Document that the Zsh
6707 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
6708 to Alexandre Duret-Lutz for this info.
6710 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

6714 2004-09-28 Paul Eggert <eggert@cs.ucla.edu>
6716 * doc/autoconf.texi (Function Portability): Fix misdescription
6717 of putenv. Problem reported by Michael Wardle.
6719 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
6721 * doc/autoconf.texi (auindex): New macro.
6722 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
6723 Problem reported by Stepan Kasal.
6725 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
6727 Fix problems reported by Andreas Buening in:
6728 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
6729 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
6731 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
6732 readable; it's not true in OS/2-emx.
6734 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6736 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6737 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6738 (trivial change). Problem and patch reported by Andrew Church in:
6739 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6741 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
6743 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
6744 three args in examples. Problem reported by Frederik Fouvry in:

6762 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
6766 * README: Add advice about m4 1.4.2.
6768 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6769 texinfo.tex for now (done by hand now).
6770 * Makefile.maint (wget_files, cvs_files):
6771 Remove ansi2knr.c; nobody uses it.
6772 (ansi2knr.c-url_prefix): Remove.
6773 (cvs-update): Fix test for failure. I don't know why it ever
6776 * doc/autoconf.texi: Update URLs, some of which went stale.
6777 Use @uref rather than @href.
6779 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6780 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6782 * config/config.guess, config/config.sub, config/elisp-comp,
6783 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6784 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6786 * NEWS, TODO, configure.ac, bin/autoscan.in,

6792 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6793 tests/tools.at, tests/torture.at:
6794 Use "file name" rather than "filename" or "path",
6795 to be consistent with the terminology of the GNU coding standards.
6797 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6799 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6800 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6801 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6802 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6804 More fixes to support spaces in the name of the build directory.
6805 This isn't a complete fix but it's an improvement.
6807 * bin/autoconf.as (autom4te_options): New var.
6808 Use it instead of appending to AUTOM4TE, so that we can allow
6809 spaces in the build directory's absolute name.
6810 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6811 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6812 AT_CHECK_NOESCAPE): Likewise.
6813 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6814 main program): Likewise.
6816 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6818 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

6824 * doc/autoconf.texi (Function Portability): Document isinf and
6825 and isnan. From a suggestion by Kevin Ryde.
6827 * lib/Autom4te/General.pm (END): Return correct exit status even
6828 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6830 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6832 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6833 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6834 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6836 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6838 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6839 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6840 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6841 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6842 * lib/autom4te.in (Automake-preselections): Preselect
6843 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6845 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6847 * lib/autom4te.in (Automake-preselections): Preselect
6848 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6851 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6853 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6855 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6856 Document problem with "`""`" in pdksh POSIX mode.
6858 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6860 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6861 with pdksh, too. Problem reported by Patrick Welche via
6863 * doc/autoconf.texi (Shellology): Note that set -o posix is
6864 useful for pkdsh, too.
6866 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6868 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6869 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6870 Don't fail if ENV or BASH_ENV is readonly.
6871 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6872 etc. are read only. Problem reported by Ludovic Courtes.
6874 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6876 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6877 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6880 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6882 * doc/autoconf.texi (File System Conventions): Warn about
6883 names like "aux". Problem reported by Eric Blake.
6885 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6886 by zero instead of array size, so that we can use any arithmetic
6887 constant expression (instead of requiring an integer constant
6888 expression). This allows us to test expressions like DBL_MAX <
6889 LDBL_MAX, which didn't conform to the C standard using the old
6891 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6892 now that we can do floating-point tests at compile time.
6894 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6896 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6897 and LDBL_EPSILON, as the resulting expression isn't an
6898 integer constant expression and violates the C standard.
6899 Problem reported by Nelson H. F. Beebe. Also, check
6900 for "L" suffix, and check that long double doesn't have
6901 worse range or precision than double, that mixed-mode
6902 arithmetic doesn't generate a diagnostic, that double
6903 constants fit in long double.
6905 2004-06-03 Kevin Ryde <user42@zip.com.au>
6907 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6908 malloc(0) and realloc(NULL,size).
6910 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6913 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6915 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6916 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6919 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6921 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6922 can be rewritten using if-then-else. Suggested by Bruno Haible.
6924 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6926 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6927 Problem reported by Stepan Kasal.
6929 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6931 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6932 change). Patch reported by Ralf Wildenhues in
6933 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6935 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6936 function F exists if the compiler and linker let you compile an
6937 expression like (F != 0). Recent versions of GCC optimize away
6938 the reference to F in that case, since every function address must
6939 be nonzero, so the link succeeds even if F does not exist.
6940 Problem reported by Manu in
6941 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6943 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6944 "Unix". Many uses changed.
6945 (Limitations of Builtins): Explain better why the ! command isn't
6948 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6950 * lib/autom4te.in (Automake-preselections): Preselect
6951 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6953 2004-05-19 Kevin Ryde <user42@zip.com.au>
6955 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6956 referencing AC_FUNC_STRERROR_R.
6958 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6959 note pessimistic assumption when cross compiling.
6961 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6963 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6964 (until 2004) invoked subcommands with sh -e, contra POSIX.
6965 Reported by Kevin Ryde.
6967 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6969 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6970 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6971 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6972 `test -f " /usr/bin/grep"', which _always_ failed.
6973 (AC_PROG_SED): Ditto bogus PATH fix.
6974 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6975 requires that grep correctly supports _multiple_ `-e' options, rather
6976 than stating only that grep should accept `-e'.
6978 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6980 Port to C99, which requires that 'exit' be declared.
6982 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6983 to ensure that stdlib.h is included.
6984 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6985 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6986 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6987 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6988 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6989 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6990 when using 'exit' in a test; C99 requires that 'exit' be declared.
6992 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6994 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6995 now prefers 'grep' implementations that accept -e.
6996 (Limitations of Usual Tools): Describe problems of traditional
6997 egrep and fgrep with long input lines, and of traditional grep
6999 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7000 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7001 All callers changed. Append /usr/xpg4/bin to the PATH, for
7003 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7004 the user with complaints about multiple -e options.
7005 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7006 Define it with AC_PROG_GREP.
7007 * configure.ac (AC_PROG_GREP): Add.
7008 * lib/freeze.mk (GREP): New macro.
7010 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7012 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7013 a possible candidate only after all others fail, rather than
7014 consulting it first. This improves backward compatibility by
7015 better reflecting the way shell selection occurred in previous
7016 versions of Autoconf, and should help to avoid triggering latent
7017 problems in other packages, such as the one in Automake where zsh
7018 is not handled robustly:
7019 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7020 Although it is not Autoconf's responsibility to work around
7021 problems in Automake, it nevertheless makes sense to avoid
7022 introducing unnecessary incompatibilites.
7024 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7025 Gary V. Vaughan <gary@gnu.org>
7027 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7028 how deeply nested we are when a suitable tool is found, set the
7029 ac_path_TOOL_found flag.
7030 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7031 nested we are in this macro. Break out of all 3 nested loops if
7032 ac_path_TOOL_found is set.
7034 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7036 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7037 of the _AS_PATH_WALK loop too if GNU flavor is found.
7039 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7041 * doc/autoconf.texi (Limitations of Make): Update documentation
7042 for `$<'. New entry `Long lines', based on a report from Simon

7044 paragraph about DJGPP, based on a mail from Richard Dawe.
7046 2004-04-20 Paul Eggert <eggert@twinsun.com>
7048 * tests/c.at (C keywords): Don't assume that GCC supports
7049 "restrict" and "inline", as sufficiently-old GCC versions do not
7050 (also, GCC configured to be in pedantic C89 mode does not).

7213 AC_SUBST provides no portable way to escape literal newlines.
7215 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7216 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7217 Darwin uses -lcrt2.o and there's little point to cataloging all

7343 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7344 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7345 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7346 not <inttypes.h>. Problem reported by Tim Mooney in

7351 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7352 otherwise "make check" fails because it forbids cmp (I guess
7353 because cmp treats files as binary on DOS-like systems).

7368 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since

7400 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7401 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7402 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7403 AC_COMPILE_IFELSE, since we now assume our caller invokes
7404 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7405 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7406 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7407 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7409 2004-01-07 Paul Eggert <eggert@twinsun.com>
7411 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7412 `"'...'"`, as it's confusing (and I suspect it may not work on
7413 some platforms). The code was incorrect anyway, as it assumed
7414 that \$ evaluated to itself in that context. Reported by
7415 Alexandre Duret-Lutz.
7417 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

7449 Bug reported by David Relson in
7450 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.

7470 -c -o might not work. From a suggestion by Kevin Ryde.
7471 (C Compiler, Generating Sources, Limitations
7472 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7473 Don't put '-o' after non-options, as POSIX doesn't allow this.

7485 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7487 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7488 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

7771 Problems reported by Eric Sunshine.
7773 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7775 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7776 -mGLOB_options_string stuff for Intel ifc, which can cause
7777 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

7800 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7801 cache variable instead of $G77 to decide whether to include -O2,
7802 since $G77 is specific to Fortran 77.
7804 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7806 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7807 free" flag. Re-order flags tested into rough order of popularity.
7809 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7811 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7812 arguments so that it can be used with syntax identical to

7888 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7889 directory for AC_CONFIG_COMMANDS' first argument exists.
7890 This makes valid the invocation of _AC_SRCPATH that follows.
7891 Reported by Eric Sunshine.
7892 * doc/autoconf.texi (Configuration Commands): Adjust.

7915 The test suite are sometimes assigning timings incorrectly.
7916 Reported by Henk Krus.
7917 Diagnosed by Nicolas Joly.
7919 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7921 Instead of making AT_help a sequence of assignments to grow

7925 (at_times_skip): Flip the meaning and rename as...

7937 (ifnames): chmod -w.
7938 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7939 executables, not bin/ executables! Otherwise all the magic needed
7940 to find non installed files is turned off. This caused a failure
7941 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7942 as found in its environment (sent by tests/autoreconf): pointing
7943 to bin/autom4te that could not find its files.
7944 * tests/mktests.sh: Force the replacement of generated files, for
7945 the sake of "mv" program that are interactive when overwriting a

8022 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8023 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8025 2003-09-04 Akim Demaille <akim@epita.fr>
8027 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8030 2003-09-04 Akim Demaille <akim@epita.fr>
8032 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8033 (freeze): When exiting, use $exit_code.
8034 * lib/autoconf/fortran.m4: Comment changes.
8036 2003-09-04 Akim Demaille <akim@epita.fr>
8038 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8040 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8042 Add support for newer Fortran dialects. The F77 interface is
8043 unchanged, and continues to support Fortran 77. New FC macros
8044 correspond to all the old F77 macros, with output variables FC,
8045 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8046 available dialect, but older dialects can be specified. There are
8047 new macros AC_FC_SRCEXT to set the source extension, and
8048 AC_FC_FREEFORM to accept free-form source files.
8050 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8052 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8053 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

8063 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
8064 AC_FC_SRCEXT, AC_FC_FREEFORM):
8066 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
8067 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8068 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8069 Rewrite in terms of the above.
8070 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8071 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8072 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8073 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8075 2003-09-02 Paul Eggert <eggert@twinsun.com>
8077 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8078 Document problems with timestamp resolution that 'make', 'cp -p', and
8081 2003-08-27 Akim Demaille <akim@epita.fr>
8083 * tests/m4sugar.at (cross_warning): Make sure to enable the
8084 output, so that we can track spurious m4sugar output.
8085 * tests/local.at: Require 2.57.
8086 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8087 are defaulted by AT_CHECK anyway.
8088 Use AT_CHECK_AUTOM4TE.
8089 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8092 2003-08-27 Akim Demaille <akim@epita.fr>
8094 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8095 when -Wobsolete is set.
8096 Set it on by default.
8097 Suggested by Klee Dienes.
8099 2003-08-27 Akim Demaille <akim@epita.fr>
8101 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
8105 2003-08-26 Akim Demaille <akim@epita.fr>

8110 2003-08-25 Akim Demaille <akim@epita.fr>
8112 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
8115 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
8117 * bin/autoreconf.in (parse_args): Do not pass --no-force to
8118 Automake versions prior to 1.8.
8120 2003-08-25 Akim Demaille <akim@epita.fr>
8122 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.
8125 2003-08-24 Akim Demaille <akim@epita.fr>

8133 * Makefile.cfg (local-checks-to-skip): New.
8134 * Makefile.maint (local-check): Rename as...
8135 (local-checks-available): this.
8138 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
8139 * configure.ac: Require Automake 1.7.6.
8141 2003-08-22 Akim Demaille <akim@epita.fr>
8143 Output stack traces in warnings.
8145 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8146 Replace the former...
8147 (m4_warn): Pass the call stack to _m4_warn.
8148 * bin/autom4te.in: Adjust to output the call stack.
8149 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8151 2003-08-22 Akim Demaille <akim@epita.fr>
8153 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8154 * bin/autom4te.in: Adjust.
8156 2003-08-21 Akim Demaille <akim@epita.fr>
8158 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8160 (&getopt): Adjust the note and verb channels, depending upon
8162 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8163 * bin/autoupdate.in: Adjust.
8164 Use &verb, not &verbose.
8166 2003-08-21 Akim Demaille <akim@epita.fr>
8168 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8170 ($help): Use Autom4te::ChannelDefs::usage.
8171 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8172 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8174 2003-08-21 Akim Demaille <akim@epita.fr>
8176 First stab at preserving warnings between calls to autom4te,
8177 including when the cache is used.
8179 There are still several issues: (i) there are too many runs of m4
8180 (one for include, one for warnings, and some more), (ii) warnings
8181 spreading on several lines are not handled gracefully, (iii) the
8182 code meant to have the call stack display for errors does not work
8183 (its handling should move from m4 to autom4te).
8185 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8187 (@preselect): Add m4_warn.
8188 ($exit_status): Remove, use $exit_code.
8189 ($help): Use Autom4te::ChannelDefs::usage.
8190 (&handle_m4): No longer define the m4_warnings.
8191 At each run, extract and report the warnings.
8192 Always cache the result, including if the exit status is on
8193 failure, since if nothing changes, we should result in the same
8194 failure, hence we can use the cache.
8195 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8196 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8198 (m4_warn): Redefine as a do-nothing: it is its invocation that
8199 matters, as warnings are now reported via traces.
8200 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8201 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8202 the latter reveals calls to the former.
8206 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8208 2003-08-21 Akim Demaille <akim@epita.fr>
8210 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8213 2003-08-21 Akim Demaille <akim@epita.fr>
8215 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8217 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8218 (&parse_warnings): Accept a list of warning requests.
8219 (&usage): Return a string, not a side effect.
8220 (cross): New warning category.
8222 2003-08-21 Akim Demaille <akim@epita.fr>
8224 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8225 (&require_configure_ac): Accept an optional directory argument.
8226 ($configure_ac): Remove.
8227 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8229 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8230 * bin/autoscan.in: Adjust.
8232 2003-08-20 Akim Demaille <akim@epita.fr>
8234 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8235 Reported by Alexandre Duret-Lutz.
8237 2003-08-20 Akim Demaille <akim@epita.fr>
8239 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8240 * bin/autom4te: Adjust.
8241 In particular, be Autoconf tools are really silent when properly
8242 working, bind the verbosity of the 'note' channel to $verbose.
8243 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8244 (&xsystem, &contents): Remove, since they are exported by...
8245 * lib/Autom4te/FileUtils.pm: this.
8247 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8248 * lib/Autom4te/FileUtils.pm: here.
8250 2003-08-20 Akim Demaille <akim@epita.fr>
8252 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8253 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8256 2003-08-20 Akim Demaille <akim@epita.fr>
8258 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
8259 (autom4te-update): New.
8260 * Makefile.cfg (update): Bind autom4te-update.
8262 2003-08-19 Derek Price <derek@ximbiot.com>

8268 package specific options and associated help.
8270 2003-08-19 Akim Demaille <akim@epita.fr>

8274 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
8276 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8278 * lib/autom4te.in (Automake-preselections): Preselect
8279 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8282 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8284 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
8285 (Autoconf-without-aclocal-m4): ... this new language.
8286 * doc/autoconf.texi (autom4te Invocation): Mention
8287 Autoconf-without-aclocal-m4.

8298 2003-08-16 Derek Price <derek@ximbiot.com>
8300 * doc/autoconf.texi (Writing testsuite.at): Document defaults for
8301 STDOUT & STDERR arguments.
8303 2003-08-14 Derek Price <derek@ximbiot.com>
8305 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8306 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8307 shorter column three. Add DESCRIPTION to log file content.
8309 2003-08-13 Derek Price <derek@ximbiot.com>
8311 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8314 2003-08-12 Derek Price <derek@ximbiot.com>
8316 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8317 (AT_CHECK_NOESCAPE): Move core functionality to...
8318 (_AT_CHECK): ...this new macro.
8320 2003-08-07 Derek Price <derek@ximbiot.com>
8322 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8323 (AT_CHECK_NOESCAPE): ...to this new macro.
8325 2003-07-31 Paul Eggert <eggert@twinsun.com>
8327 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8328 in Bash 2.01. Problem reported by Brian Gough in
8329 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8331 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8333 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8334 -lcrt1.o, for OS X. (trivial change)
8336 2003-07-07 Paul Eggert <eggert@twinsun.com>
8338 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8339 inside '#ifndef __cplusplus'. Problem reported by
8342 2003-07-06 Bill Clarke <llib@computer.org>
8344 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8345 'long', not 'int', for benefit of Sun's recent C++ compilers
8346 (trivial change). See:
8347 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8348 (This really should be 'intptr_t', not 'long', but that would
8351 2003-06-25 Akim Demaille <akim@epita.fr>
8353 * lib/Makefile.am (autom4te.cfg): Make it read only.
8354 Depend on Makefile since it contains substitutions.
8356 * lib/autom4te.in (args): Add local.at? for Autotest args.
8357 This change was made on autom4te.cfg which is generated.
8358 Reported by Raja R. Harinath.
8360 2003-06-25 Akim Demaille <akim@epita.fr>
8362 * doc/autoconf.texi (Header Portability): sys/mount.h.
8363 From Gareth McCaughan.
8365 2003-06-23 Akim Demaille <akim@epita.fr>
8367 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8368 not all of them. This fixes 1. the fact that when testing
8369 Autoconf there are many many config.log, 2. the incorrect use of
8370 top_srcdir to find config.log.
8371 Don't mix the detailed output of failed test with the summary of
8372 failures. Rather, append detailed log afterwards.
8374 2003-06-23 Akim Demaille <akim@epita.fr>
8376 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8377 always run: output config.log on $at_group_log.
8379 2003-06-23 Akim Demaille <akim@epita.fr>
8381 * tests/torture.at (#define header templates): Don't use quotes in
8382 C++ comments as it puzzles Emacs' sh font-lock-mode.
8384 2003-06-23 Akim Demaille <akim@epita.fr>
8386 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8387 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8388 * tests/atspecific.m4: Rename as...
8389 * tests/local.at: This.
8390 * tests/suite.at: Move the globals into...
8391 * tests/local.at: here.
8392 * tests/Makefile.am: Adjust.
8393 * doc/autoconf.texi (testsuite Scripts): Adjust.
8395 2003-06-21 Kevin Ryde <user42@zip.com.au>
8397 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8398 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8399 ensuring we add -std1 for full-ANSI.
8401 * doc/autoconf.texi (hdrindex): New macro.
8402 Add index entries for portability of various standard header files.
8404 2003-06-20 Akim Demaille <akim@epita.fr>
8406 * configure.ac: Bump to 2.57b.
8408 2003-06-20 Akim Demaille <akim@epita.fr>
8412 2003-06-20 Akim Demaille <akim@epita.fr>
8414 * bin/autom4te.in: Don't rely on $HOME being defined.
8415 Reported by Marc Espie as PR/233.
8417 2003-06-20 Akim Demaille <akim@epita.fr>
8419 * lib/autotest/general.m4: Use at_times_file only if used.
8422 2003-06-20 Akim Demaille <akim@epita.fr>
8424 * config/config.guess, config/config.sub, config/elisp-comp,
8425 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8426 Update from masters.
8428 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8430 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8431 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8432 (TEST_SCRIPT): New diversion.
8433 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8434 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8435 (AT_INIT): Support for expected failures.
8437 2003-06-02 Akim Demaille <akim@epita.fr>
8439 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8441 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8442 Autoconf nor Automake.
8443 (&contents): New, from Automake.
8446 2003-05-28 Paul Eggert <eggert@twinsun.com>
8448 * NEWS, doc/autoconf.texi (Particular Functions),
8449 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8450 is the inverse of localtime.
8452 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8454 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8455 (handle_exec_errors): New function. Work around $! being
8456 altered by WEXITSTATUS.
8457 (xqx, xsystem): Use handle_exec_errors.
8459 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8461 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8462 Do not call `_exit()', simply modify `$?'.
8463 (xsystem): Reset $! before running system, and check it afterward.
8464 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8465 63 for version mismatches.
8467 2003-05-23 Akim Demaille <akim@epita.fr>
8469 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8470 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8471 the middle of a line).
8472 * lib/m4sugar/m4sugar.m4: Likewise.
8473 Remove useless spaces in comments.
8475 2003-05-23 Akim Demaille <akim@epita.fr>
8477 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8478 exit 63, so that we (or Automake's "missing") can tell the
8479 difference with a plain failure.
8480 * doc/autoconf.texi (Notices): Adjust.
8482 2003-05-23 Akim Demaille <akim@epita.fr>
8484 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8485 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8486 White spaces cleanup.
8488 2003-05-22 Jim Meyering <jim@meyering.net>
8489 Paul Eggert <eggert@twinsun.com>
8491 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8492 Remove `#include <stdlib.h>' from the list; we should never
8493 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8494 resulting namespace pollution would cause other tests to fail.
8495 Configure scripts run with some older versions of g++ and HP's
8496 aCC would fail due to such an #include. Problems reported by
8497 Matthew Mueller in <http://bugs.debian.org/120704> and by
8499 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8500 In the test, use the test declaration before including <stdlib.h>,
8501 as that's closer to how it'll be used.
8503 2003-05-23 Akim Demaille <akim@epita.fr>
8505 * doc/autoconf.texi (Header Portability): ucred.h.
8508 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8510 Overhaul Autotest's logging: generate separate log files
8511 in testsuite.dir/NNN/testsuite.log, and append them to
8512 testsuite.log instead of re-running the test verbosely.
8514 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8515 file descriptor, write 0 to at_status_file instead of setting
8516 at_status=0, initialize some new variables (at_status_file,
8517 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8518 to rerun the tests, instead append the at_group_log to the
8519 at_suite_log when a test fails.
8520 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8521 with the AS_MESSAGE_LOG_FD redirected to stdout.
8522 (AT_CLEANUP): save the output status in $at_status_file
8523 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8525 (AT_CHECK): since tests are run with a redirected stdout,
8526 and used to be re-run in verbose mode, turn some $at_verbose
8527 into echo, and don't redirect the output of testing stdout

8651 2003-05-06 Akim Demaille <akim@epita.fr>
8653 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8654 longer updates aclocal.m4 if useless, (ii) if a file m4_included

8929 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8930 defined, to support freestanding compilers. This should fix the
8931 bug reported by Momchil Velkov in
8932 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8934 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

8970 * Makefile.maint: Sync with Bison, i.e.:
8971 (po-check): Scan .l and .y files instead of the
8972 .c and the .h files that they generate. This fixes the bug
8973 reported by Tim Van Holder in:

9030 Reported by Ezra Peisach.
9032 2002-11-05 Akim Demaille <akim@epita.fr>
9034 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9036 We _have_ to stop using the old compatibility scheme that tried to
9037 avoid useless backslashes because Libtool 1.4.3 contains a
9038 AC_DEFINE([error_t], [int],
9039 [Define to a type to use for \`error_t' if it is not
9040 otherwise available.])
9041 We _have_ to quote the single quote and backslashes with \. The
9042 old compatibility scheme saw that ` was backslashed, and therefore
9043 did not quote the single quote. Hence before this patch, Autoconf
9044 was not compatible with Libtool.

9498 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9499 aclocal invocation, as Gettext macros might not be visible to
9501 Instead of blindly running autopoint, scan configure.ac (not the
9502 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.

9535 * tests/torture.at (Configuring subdirectories): Be robust to
9536 users who use config.site to require for a cache: in this case,

9573 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9574 (.m4.m4f): Don't pass --prepend-include, since that's done by
9575 tests/autom4te itself.
9576 * lib/autoscan/Makefile.am: Include freeze.mk.
9577 (autoscan.list): New target --this file is no longer a source.
9578 (autoscan.pre): New file.

9593 * lib/autoscan/autoscan.list: this.
9594 * bin/autoscan.in (&init_tables): Adjust.
9596 2002-09-28 Akim Demaille <akim@epita.fr>
9598 * lib/autoscan/functions, lib/autoscan/headers,
9599 * lib/autoscan/identifiers, lib/autoscan/makevars,

9601 `functions' line is now prefixed with `function:'.
9602 * bin/autoscan.in (&init_tables): Adjust.
9604 2002-09-28 Akim Demaille <akim@epita.fr>
9606 From now on, autoscan files must always map a macro name to a
9607 word: there is no `default' macro for autoscan.
9609 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9611 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9614 2002-09-28 Akim Demaille <akim@epita.fr>

9628 2002-09-27 Akim Demaille <akim@epita.fr>
9630 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
9632 Thanks to Bill Moseley and Paul Eggert.
9633 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
9634 the tmpdir must be created.
9635 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
9636 dir be in the build tree, instead of $TMPDIR.

9657 (Limitations of Make): Some about `Single Suffix Rules and
9658 Separated Dependencies'.
9659 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9660 (ifnames, autoscan, autom4te): Un-factor into several rules.
9662 2002-09-25 Paul Eggert <eggert@twinsun.com>
9664 * BUGS (Interoperability bugs): New section. Mention libtool
9665 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
9667 2002-09-24 Paul Eggert <eggert@twinsun.com>
9669 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
9670 make handles suffix-rules differently from GNU make.
9672 * bin/Makefile.am (SUFFIXES, .in): Remove.
9673 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
9674 Move the body of the old .in rule here.
9676 2002-09-16 Akim Demaille <akim@epita.fr>
9678 i960 compilers create `b.out' files by default.
9679 Reported by Ralf Corsepius.
9681 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
9682 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9684 2002-09-13 Paul Eggert <eggert@twinsun.com>

9687 reference to `struct timezone' in the description of

9694 * config/config.sub, config/config.guess: Update.
9695 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9696 * Makefile.am: Adjust.
9698 2002-09-13 Akim Demaille <akim@epita.fr>
9700 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9701 reading config.log when the compiler is rejected.
9702 Suggested by Guido Draheim.
9704 2002-09-13 Akim Demaille <akim@epita.fr>
9706 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9707 (chdir_init) might hang when stat'ing mounted directories.
9708 Reported by Vance Shipley.
9710 2002-09-12 Akim Demaille <akim@epita.fr>
9712 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9715 2002-09-12 Akim Demaille <akim@epita.fr>
9717 * doc/autoconf.texi (Defining Symbols): Present two different
9718 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9719 difference between 1 argument calls, and 2-3 argument calls.
9721 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9723 * doc/autoconf.texi: Review grammar and punctuation.
9725 2002-09-11 Paul Eggert <eggert@twinsun.com>
9727 * doc/autoconf.texi: Fix minor formatting, spelling, and
9729 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9730 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9733 2002-09-11 Akim Demaille <akim@epita.fr>
9735 * doc/autoconf.texi (Questions): Rename as...
9737 (Defining Directories): New.
9739 2002-09-09 Akim Demaille <akim@epita.fr>
9741 * doc/autoconf.texi (Making testsuite Scripts): Update.
9742 Suggested by Nishio Futoshi.
9744 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9746 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9747 plain `@' is wanted.
9749 2002-09-09 Akim Demaille <akim@epita.fr>
9751 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9752 `duplicates', since the algorithm was too naive and could keep
9753 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9754 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9755 Reported by Ralf Corsepius.
9756 * tests/torture.at (Configuring subdirectories): Exercise these
9759 2002-09-09 Akim Demaille <akim@epita.fr>
9761 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9762 looking for a replacement file.
9763 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9764 directory is relative.
9765 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9766 directory definition.
9767 Reported by Andreas Schwab and Jim Meyering.
9769 2002-09-06 Akim Demaille <akim@epita.fr>
9771 * doc/autoconf.texi (Setting Output Variables): Clarify what
9772 precious variables are.
9773 Suggested by Pontus Skoeld.
9775 2002-09-05 Akim Demaille <akim@epita.fr>
9777 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9778 (ifnames, autoscan, autom4te): Since we don't only depend on
9779 configure.ac variables (such as VERSION etc.), but also on prefix
9780 and so forth, depend on Makefile, not configure.ac.
9781 Reported by Alexandre Duret-Lutz.
9782 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9784 2002-09-05 Kevin Ryde <user42@zip.com.au>
9786 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9787 doesn't seem to be confined to ia64, just say "some versions".
9789 2002-09-04 Akim Demaille <akim@epita.fr>
9791 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9793 * Makefile.am (maintainer-clean-local): Remove.
9794 (MAINTAINERCLEANFILES): Remove COPYING.
9796 2002-09-03 Paul Eggert <eggert@twinsun.com>
9798 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9799 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9802 2002-09-03 Akim Demaille <akim@epita.fr>
9804 * configure.ac: Bump to 2.53d.
9805 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9806 as of today, on Automake's team suggestion.
9808 2002-09-03 Akim Demaille <akim@epita.fr>
9812 2002-09-02 Akim Demaille <akim@epita.fr>
9814 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9816 * configure.ac: Disable SITE_MACRO_DIR.
9818 2002-09-02 Jim Meyering <meyering@lucent.com>
9820 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9821 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9822 Also, tweak grammar: s/make sure to/be sure to/.
9824 2002-09-02 Paul Eggert <eggert@twinsun.com>
9826 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9827 directory names are generally preferable to physical names.
9829 2002-09-02 Akim Demaille <akim@epita.fr>
9831 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9832 Reported by Raja R. Harinath.
9833 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9834 * bin/autoupdate.in: Use error instead of die.
9836 2002-09-01 Paul Eggert <eggert@twinsun.com>
9838 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9839 ordinary shell concatenation rather than echo+tr+sed command that
9840 runs afoul of a long-line-related sed bug in Solaris 8.
9842 * bin/autoheader.in (parse_args): --warning -> --warnings.
9844 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9845 stdout, as traditional "ls" does.
9846 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9847 _AC_COMPILER_EXEEXT_O): Likewise.
9848 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9850 * bin/autoconf.as: Add --prepend-include option. This patch was
9851 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9852 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9854 * bin/autoconf.in, configure: Regenerate.
9856 * doc/autoconf.texi (Special Shell Variables): Mention
9857 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9859 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9860 MAILPATH and set PS1, PS2, PS4 to default values, to work
9861 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9862 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9863 the Autoconf documentation specifies; fall back to "unset" only if
9864 this fails. Use a shell for-loop for this rather than an m4 loop,
9865 to shorten the output script.
9867 2002-08-30 Paul Eggert <eggert@twinsun.com>
9869 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9870 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9871 for the CDPATH problem. Document PWD.
9872 (Limitations of Builtins): Document the problem that "cd $foo" and
9873 "ls $foo" may refer to different directories in shells conforming
9874 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9875 example, since the old example is now out of date.
9877 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9878 FOO" and "ls FOO" talk about different directories; this catches
9879 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9882 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9883 of rolling our own unset.
9884 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9885 in practice we needn't worry about CDPATH if unset doesn't work.
9887 * Makefile.in, aclocal.m4, bin/Makefile.in,
9888 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9889 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9890 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9891 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9892 tests/Makefile.in: Regenerate with Automake 1.6.3.
9894 * config/config.guess, config/config.sub, config/mkinstalldirs:
9897 * configure: Regenerate with self.
9899 2002-08-30 Kevin Ryde <user42@zip.com.au>
9901 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9904 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9906 * bin/autom4te.in (Request::load): Correctly test for "do" read
9909 2002-08-29 Akim Demaille <akim@epita.fr>
9911 * lib/Autom4te/General.pm (&xqx): New.
9912 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9913 hand, which is not portable.
9915 * bin/autom4te.in: Use them.
9916 Use &error instead of die.
9917 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9920 2002-08-17 Paul Eggert <eggert@twinsun.com>
9922 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9923 default list of compilers to try, since it was long ago superseded
9924 by the ksh fc builtin. Suggested by Steven G. Johnson.
9926 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9928 * doc/autoconf.texi (Invoking autom4te): End the option table,
9929 fixing a bug introduced by the previous patch.
9930 (Limitations of Make): Add a 'target lookup' subentry in the
9931 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9933 2002-07-29 Mark D. Roth <roth@feep.net>
9935 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9936 options and use $AUTOM4TE_PATH.
9937 * doc/autoconf.texi: Remove documentation of autom4te
9938 --include-envvar and --site-macro-subdir options and document
9939 use of $AUTOM4TE_PATH.
9940 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9941 arguments from each language section.
9943 2002-07-29 Paul Eggert <eggert@twinsun.com>
9945 * doc/install.texi: Include copyright symbol in copyright notice.
9947 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9949 (AM_MAKEINFOFLAGS): New macro.
9950 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9951 * Makefile.am (INSTALL): Use the new macros.
9952 Use -o rather than --output, since "missing" does not grok --output.
9954 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9956 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9957 comments do not always work. Never trust the exit status of
9960 2002-07-24 Kevin Ryde <user42@zip.com.au>
9962 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9963 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9965 2002-07-23 Paul Eggert <eggert@twinsun.com>
9967 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9968 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9969 apparently treats PATH="nonexistent" as if it contained ".".
9970 Bug reported by Stefan `Sec' Zehl.
9972 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9974 * doc/autoconf.texi (Limitations of Make): Mention the special
9975 handling of the obj/ directory by BSD make.
9977 2002-07-20 Kevin Ryde <user42@zip.com.au>
9979 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

10011 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
10012 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
10014 2002-07-17 Russ Allbery <rra@stanford.edu>
10016 * doc/autoconf.texi (Initializing configure): Clarify the
10017 description of the tarname default.
10019 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
10021 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10022 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10023 latter was not run.
10025 2002-07-17 Akim Demaille <akim@epita.fr>
10027 * lib/Autom4te/General.pm (find_file): Browse the directories in
10028 the order they are given.

10047 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
10048 macro directory, remove note that include path directories are
10049 used in reverse order, and document --prepend-include option.
10050 * lib/autom4te.in: Use --prepend-include instead of --include.

10240 This improves on an earlier suggestion by H. Peter Anvin.
10242 2002-05-16 Paul Eggert <eggert@twinsun.com>
10244 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10245 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10246 Both macros now accept an optional source-dir arg.
10247 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10249 * NEWS: Document this.
10250 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10252 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10253 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10254 not for GNU extensions; this undoes part of the 2000-11-03 change,
10255 reverting to 2.13-compatible behavior.

10263 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10264 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10265 and it causes a 'test' syntax error if it fails.
10266 Bug reported by Stephen Gildea.
10268 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10269 If prototypes are supported, use them to check this at compile-time,
10270 instead of trying to check it at run-time. If we must do a run-time
10271 check, assume that setvbuf is standard when cross-compiling, as
10272 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10273 Bug reported by Paul D. Smith.
10275 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10276 argument specifying location of getloadavg.c. This removes a
10277 FIXME. This idea was taken from Jim Meyering's implementation in
10279 * doc/autoconf.texi (Particular Functions): Document this.
10280 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10281 that's what the code does; this fixes a bug reported by

10286 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10287 autopoint instead of gettextize.
10288 ($uses_alocal): Rename as...
10289 ($uses_aclocal): this.
10290 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10291 Suggested by Bruno Haible.
10293 2002-05-03 Akim Demaille <akim@epita.fr>
10295 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10297 2002-04-29 Paul Eggert <eggert@twinsun.com>
10299 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10300 files to be 1 second older; just set them to be the same time.
10301 Also, sleep 1 second after the first aclocal, to work around
10302 problems with sub-second time stamps on the input files.
10304 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10306 * doc/autoconf.texi: Mention "set -e -x" lossage
10307 under node "Limitations of Builtins".

10313 From Christian Cornelssen.
10315 2002-04-29 Akim Demaille <akim@epita.fr>
10317 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10318 of lack of $LINENO support, then the test will compare the $LINENO
10319 in testsuite vs. the lineno in the test file. This is wrong, of
10321 Be sure to protect it.
10322 Reported by Patrick Welche.
10324 2002-04-25 Akim Demaille <akim@epita.fr>
10326 * doc/autoconf.texi (Obsolete Macros): Typo.
10327 Reported by Vladimir Volovich.
10329 2002-04-25 Akim Demaille <akim@epita.fr>
10331 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10332 than some of the input files, hence, on the second run of aclocal,
10333 if some of its input are younger, make them older.
10334 Suggested by Paul Eggert.
10336 2002-04-25 Akim Demaille <akim@epita.fr>
10338 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

10347 (_AC_INIT_PREPARE): Use them to log them.
10348 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10349 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10350 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10351 _AC_SUBST_FILES and _AC_SUBST_VARS.
10352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10354 2002-04-24 Akim Demaille <akim@epita.fr>
10356 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10357 autoheader, so that automake does not complain about a missing
10358 config.h.in that was to be created.
10360 2002-04-23 Akim Demaille <akim@epita.fr>

10547 (_AC_COMPILER_OBJEXT): Use them.
10548 Fixes Debian #138666.
10550 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10552 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10554 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10555 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10556 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10557 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10558 (AC_C_CONST): Same.

10570 2002-03-28 Kevin Ryde <user42@zip.com.au>
10572 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10573 to avoid versions of HP C which don't allow that.
10575 2002-03-27 Paul Eggert <eggert@twinsun.com>

10589 2002-03-25 Paul Eggert <eggert@twinsun.com>
10591 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10592 as POSIX requires, as it doesn't work with Zsh.
10593 * doc/autoconf.texi (Assignments): Document the problem.
10595 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

10604 problem with here-document buffer boundaries.
10606 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10607 when reinvoking the shell, to work around problems with installers
10608 who put strange things like "cd" commands in their environments.

10633 (Limitations of Usual Tools): Add mkdir section.
10635 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10636 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10637 back on AS_DIRNAME to compute prefixes otherwise; this is
10638 roughly what mkinstalldirs does. That way, we need not have
10639 our own filename disassembler. The old disassembler did not
10640 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10642 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10643 Create at_test_all by a series of assignments,
10644 not by a single assignment of a long string. The latter causes ksh
10645 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10646 presumably because of a buffer overrun.
10648 2002-03-14 Paul Eggert <eggert@twinsun.com>
10650 * lib/autotest/general.m4 (at_times_skip):
10651 Renamed from at_times. Now a boolean.
10652 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10653 says 'times: not found'.

10657 * bin/autoreconf.in (&study_gettextize): New.
10658 (&autoreconf): Handle newest gettextize.

10700 2002-03-08 Akim Demaille <akim@epita.fr>
10702 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10703 aliases the actual variables, and modifications of the former
10706 2002-03-08 Akim Demaille <akim@epita.fr>
10708 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10709 because of C-c: have m4 output in tmp files, then mv them.

10733 * lib/autoconf/general.m4 (AC_INIT): More informative error
10734 message for LIBOBJ.
10736 2002-03-04 Akim Demaille <akim@epita.fr>

10741 2002-03-04 Akim Demaille <akim@epita.fr>
10743 * doc/autoconf.texi (Transforming Names): Equality between target
10744 and host is irrelevant.
10745 (Specifying Names, Canonicalizing): Remove all references to the
10746 backward compatibility hooks. Rather, collect them all into...
10747 (Hosts and Cross-Compilation): this new section.
10748 * doc/install.texi (System Type): Ditto.
10749 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10750 that `--host' implies cross-compilation.
10752 2002-03-04 Akim Demaille <akim@epita.fr>
10754 * doc/autoconf.texi (Evaluation Macros): New.
10755 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10757 (_m4_foreach): Define the variant with immediate evaluation so
10758 that it contains exactly the items, not an expression which
10759 evaluation is the current item.
10760 (m4_re_string, m4_re_word): Don't over quote them.
10762 2002-03-04 Akim Demaille <akim@epita.fr>
10764 Instead of having stacking `shift's evaluated at the end, let
10765 `foreach' loops immediately evaluate them.
10767 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10768 $*. This is the n-th time I change my mind, but hopefully this is
10771 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10773 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10774 it was only a hack for m4_text_wrap.
10775 (m4_car2): Remove, replaced by...
10777 (_m4_foreach): Adjust.
10778 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10779 m4_bpatsubst for clarification.

10939 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10940 AUTOTEST_PATH *after* it was set.
10941 Don't put `.' in the PATH: the user should be precise and `./' if
10942 needed. In addition, given that the test suite does some `cd', if
10943 `.' is in the path, the `tested programs' sections will report
10944 programs found in the test suite's directory, while during the
10945 tests (performed in their own directory), these programs are no
10946 longer visible. In other words, the results is confusing and

11023 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11024 and PACKAGE_BUGREPORT from here...

11055 trailing files, don't apply `-rf' to files which might not be
11056 created by configure (core, core.*, and *.core), but just `rm -f'.
11057 Suggested by Jonathan Kamens.
11059 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11061 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11063 2001-12-14 Akim Demaille <akim@epita.fr>
11065 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11067 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11069 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11070 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11071 abs_srcdir, top_srcpath to abs_top_srcdir.
11072 (_AC_OUTPUT_FILES): Adjust.
11073 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11074 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11075 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11077 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11079 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11080 C/Fortran linking on HP/UX, by extracting the Fortran library
11081 search path from the LPATH line in the $F77 -v output.
11083 2001-12-12 Kevin Ryde <user42@zip.com.au>
11085 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11086 forbidden file descriptors table.
11088 2001-11-26 Akim Demaille <akim@epita.fr>
11090 * bin/autoscan.in (%c_keywords): Build it at top level.
11091 Map to 1 in order to simplify its uses.
11093 2001-11-26 Akim Demaille <akim@epita.fr>
11095 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11096 Remove $filepath, useless.
11097 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11098 variables, they are really part of the tokens.
11099 Split the input line on spaces and then look for tokens.
11100 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11101 because of `lex$U.$(OBJEXT)'.
11102 (&scan_files): Use "@list" instead of join.
11103 * doc/Makefile.am (CLEANFILES): Add *.fns.
11105 2001-11-26 Akim Demaille <akim@epita.fr>
11107 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11108 Remove, replaced by...
11109 * tests/wrappl.in: Be common for all the Perl executables.
11110 In particular autoscan and autoheader want -I.
11111 * configure.ac: Adjust.
11112 * lib/autoscan/headers: errno.h is portable.
11114 2001-11-26 Akim Demaille <akim@epita.fr>
11116 * bin/autoscan.in (used): New.
11119 2001-11-26 Akim Demaille <akim@epita.fr>
11121 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11123 (&scan_sh_file): Remove a duplicate pattern.
11124 (&check_configure_ac): Use long options.
11125 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11127 2001-11-26 Akim Demaille <akim@epita.fr>
11129 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11130 Before, having a line containing the opening of a multi line
11131 comment made the whole line be ignored.
11133 2001-11-26 Akim Demaille <akim@epita.fr>
11135 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11136 (testsuite Scripts): Be one of its subsection.
11137 (Autotest Logs): New.
11139 2001-11-26 Akim Demaille <akim@epita.fr>
11141 Test groups are now run two directories deeper.
11143 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11144 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11146 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11147 top_srcdir, builddir and top_builddir.
11148 Use `at_*dir' relatively to the directory containing the
11149 suite, use `*dir' when relatively to the current group dir.
11151 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11153 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11154 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11155 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11158 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11160 * doc/autoconf.texi (Using System Type): Add an example of `case
11161 $host' usage so people quit using `case $target' everywhere.
11163 2001-11-22 Akim Demaille <akim@epita.fr>
11165 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11166 spotted by Jim Meyering.
11168 2001-11-16 Paul Eggert <eggert@twinsun.com>
11170 This patch implements a `long double' suggestion by Oliver Kiddle.
11172 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11173 static, to catch errors if the value isn't known at compile-time
11174 and the compiler supports dynamic arrays. Change its name from
11175 `_array_' to `test_array' to avoid potential name clashes.
11176 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11177 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11178 better than double. Catch a bug in GCC 2.95.2 x86.
11179 * doc/autoconf.texi (C Compiler): Document the above.
11182 2001-11-13 Akim Demaille <akim@epita.fr>
11184 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11186 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11188 2001-11-13 Akim Demaille <akim@epita.fr>
11190 * lib/autotest/general.m4 (AT_INIT): After having run the test
11191 group, go back to the initial directory, not to at_suite_dir.
11193 2001-11-13 Akim Demaille <akim@epita.fr>
11195 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11196 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11197 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11199 (AT_CHECK_CONFIGURE): Use absolute paths.
11200 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11201 The problem is still the old one: there is no means in M4 (that I
11202 know about) to create a defining macro, because there is no means
11203 to create `$1' etc., therefore, the defining macro ``swallows''
11204 all the arguments meant to the defined macro.
11206 2001-11-13 Akim Demaille <akim@epita.fr>
11208 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11209 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11211 * tests/aclocal.m4: Remove, as it is no longer used.
11213 2001-11-13 Akim Demaille <akim@epita.fr>
11215 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11216 variable names when referring to a single test group, or to
11217 `suite' when referring to the whole test suite.
11218 `at_last_test' is removed: m4 compute at_format itself.
11219 (at_stdout, at_stder1, at_stderr): New variables.
11220 (AT_CHECK): Use them.
11222 2001-11-13 Akim Demaille <akim@epita.fr>
11224 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11226 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11227 Do it as soon as a test fails, don't wait till the end of the test
11229 Don't remove $as_me.[0-9]*, since these files no longer exist.
11231 2001-11-13 Akim Demaille <akim@epita.fr>
11233 * tests/tools.at: Use absolute paths, since we are no longer run
11236 2001-11-13 Akim Demaille <akim@epita.fr>
11238 Now that tests are running in their own private dir, there is no
11239 need to list the files to remove at the end of tests groups.
11241 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11242 (AT_data_files, at_data_files): Remove.
11243 (AT_CLEANUP, AT_DATA): Simplify.
11245 Remove the group dir if !debug && !failed.
11246 * tests/atspecific.m4: Adjust.
11248 2001-11-13 Akim Demaille <akim@epita.fr>
11250 Start a new layout for Autotest: `testsuite' creates
11251 `testsuite.dir' in which the at-check-line etc. files are to be
11252 found, and `testsuite.dir/003' where the test group 3 is run.
11254 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11255 at_check_line_file, at_format, at_test_normalized, at_group_dir
11257 Create the directories.
11258 Use absolute paths for at- files.
11259 (AT_CHECK): Adjust.
11261 2001-11-11 Michael Matz <matz@kde.org>
11263 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11265 (m4_car): Properly quote arguments.
11267 2001-11-13 Akim Demaille <akim@epita.fr>
11269 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11270 with stricter rules on LIBOBJS.
11272 2001-11-12 Paul Eggert <eggert@twinsun.com>
11274 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11275 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11278 2001-11-12 Akim Demaille <akim@epita.fr>
11280 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11282 2001-11-12 Akim Demaille <akim@epita.fr>
11284 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11285 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11286 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11287 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11288 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11289 specify to what the macro should be defined (typically to 1).
11291 2001-11-12 Akim Demaille <akim@epita.fr>
11293 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11296 2001-11-12 Akim Demaille <akim@epita.fr>
11298 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11299 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11300 definition used by Automake where LEX is +/- "${missing} lex" and
11301 `missing' itself contains variables.
11303 2001-11-12 Akim Demaille <akim@epita.fr>
11305 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11306 Now that M4sh pushes BODY, the comments were output at the end of
11309 2001-11-08 Akim Demaille <akim@epita.fr>
11311 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11312 that we can trace macros from aclocal.m4.
11313 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11314 obsoleted, and redirect to the former anyway.
11315 Reported by Ralf Corsepius.
11317 2001-11-08 Akim Demaille <akim@epita.fr>
11319 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11320 processed only if present.
11321 * tests/torture.at (Configuring subdirectories): Use autoreconf
11322 instead of successive calls to autoconf.
11323 Add a nonexistent subdirectory to exercise the patch above.
11324 Reported by Ralf Corsepius.
11326 2001-11-08 Kevin Ryde <user42@zip.com.au>
11328 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11329 doesn't accept .S files.
11331 2001-11-07 Akim Demaille <akim@epita.fr>
11333 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11334 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11335 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11336 * bin/autom4te.in (warn_forbidden): New.
11337 (handle_output): Use it.
11338 Read m4_pattern_forbid with messages.
11340 2001-11-05 Akim Demaille <akim@epita.fr>
11342 * bin/autom4te.in (--normalize): Remove.
11343 * lib/autom4te.in: Adjust.
11345 2001-11-05 Akim Demaille <akim@epita.fr>
11347 * tests/Makefile.am (testsuite): Rename this target as...
11348 ($(TESTSUITE)): this.
11351 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11353 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11354 the --prefix option, also remove it's argument.
11356 2001-11-05 Akim Demaille <akim@epita.fr>
11358 * doc/autoconf.texi (testsuite Invocation): Update.
11359 (Writing testsuite.at): Update.
11361 2001-11-03 Akim Demaille <akim@epita.fr>
11363 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11365 2001-11-03 Akim Demaille <akim@epita.fr>
11367 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11368 (&file_name_is_absolute): New, wrappers around routines from
11370 Use and export them.
11371 (&find_configure_ac): Optionally take a directory where to look at.
11372 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11374 Default @ARGV to `.', not find_configure_ac.
11375 (&autoreconf): Argument is a directory.
11376 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11377 * doc/autoconf.texi (autoreconf Invocation): Update.
11379 2001-11-03 Akim Demaille <akim@epita.fr>
11381 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11382 (@export_forward_subs): New.
11383 Add basename, dirname, and fileparse.
11385 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11386 Don't look for aclocal flags if we already know aclocal is not
11388 Move aclocal.m4t only if it exists.
11389 Reported by Ezra Peisach.
11391 2001-11-03 Akim Demaille <akim@epita.fr>
11393 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11394 passed on command line, defaulting to ./configure.ac if present.
11395 (&maybe_autoreconf, File::Find): Remove, unused.
11396 (&autoreconf): If autoconf is not used, don't try to trace.
11398 2001-11-02 Akim Demaille <akim@epita.fr>
11400 * configure.ac: Bump to 2.52g.
11402 2001-11-02 Akim Demaille <akim@epita.fr>
11406 2001-11-02 Akim Demaille <akim@epita.fr>
11408 * config/config.guess, config/config.sub, doc/standards.texi:
11409 * config/lispdir.m4: Update from masters.
11410 * configure.ac: Bump to 2.52f.
11412 2001-11-02 Akim Demaille <akim@epita.fr>
11414 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11415 Don't run aclocal when aclocal.m4 is not from aclocal.
11417 Don't run libtoolize and gettextize if --install is not given.
11419 2001-11-01 Paul Eggert <eggert@twinsun.com>
11421 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11422 be invoked before _AS_LINENO_PREPARE.
11423 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11424 than character ranges.
11426 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11427 invoking AS_BASENAME. Set the locale variables to 'C' if
11428 possible, as POSIX requires this to get the traditional
11430 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11432 2001-10-31 Paul Eggert <eggert@twinsun.com>
11434 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11435 with {}, as that triggers a bug in Bash 2.05.
11437 (_AS_LINENO_PREPARE): Use Sed rather than
11438 Awk. Fix the sed prepass to work even if there are multiple
11439 instances of $LINENO on the same line. Do not substitute for
11440 other variables like $LINENOT. Do not check file dates; such a
11441 check is unreliable on sufficiently fast machines, and removing
11442 the check makes the code simpler and more reliable. Check for
11443 output and chmod failures.
11445 * doc/autoconf.texi (Special Shell Variables): Document
11448 2001-10-31 Akim Demaille <akim@epita.fr>
11450 * tests/Makefile.am (atconfig): Remove this target, Automake
11453 2001-10-31 Akim Demaille <akim@epita.fr>
11455 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11456 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11457 provided, while it is optional.
11458 * configure.ac: Adjust.
11460 2001-10-26 Paul Eggert <eggert@twinsun.com>
11462 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11463 lib/Autom4te/Struct.pm:
11464 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11467 * doc/autoconf.texi (Special Shell Variables): Document some
11468 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11470 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11471 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11472 eval $LINENO is not portable in practice.
11474 2001-10-24 Akim Demaille <akim@epita.fr>
11476 * lib/Autom4te/General.pm (backname): New.
11478 2001-10-24 Akim Demaille <akim@epita.fr>
11480 * m4/: Remove, merged into...
11483 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11485 * doc/autoconf.texi (Shellology): Mention the problems with bash
11486 2.05's use of ANSI quoting in its `set' builtin.
11488 2001-10-22 Paul Eggert <eggert@twinsun.com>
11490 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11491 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11492 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11493 POSIX decided to standardize on the int flavor of strerror_r.
11494 Always do char* test, as there's no reason not to.
11495 Assign to a char* var, to catch strerror_r that returns int*.
11497 * doc/autoconf.texi (Particular Functions):
11498 Document the above changes. Also, document the fact that
11499 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11501 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11503 2001-10-20 Akim Demaille <akim@epita.fr>
11505 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11506 the executable was missing from the log.
11508 2001-10-20 Akim Demaille <akim@epita.fr>
11510 * lib/Autom4te/General.pm (&update_file): If destination is
11511 unchanged, remove the source.
11512 (&up_to_date_p): Don't be verbose, be debug.
11513 * bin/autoreconf.in: No longer support --m4dir.
11514 (&autoreconf): Display the full path of the configure.ac we are
11516 Trace it only once.
11517 Be sure to honor --force with gettextize.
11518 Always run aclocal.
11519 * doc/autoconf.texi: Adjust.
11521 2001-10-20 Akim Demaille <akim@epita.fr>
11523 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11525 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11526 `intl' is already present, as it refuses unless --force.
11527 (&parse_args): Use -I, --include instead of the old Autoconf
11529 ($localdir, $autoconf_dir): Remove.
11531 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11533 2001-10-19 Jens Petersen <petersen@redhat.com>
11535 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
11536 * doc/autoconf.texi (Particular Programs): Likewise.
11538 2001-10-19 Akim Demaille <akim@epita.fr>
11540 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11541 file in @configure_input@.
11542 Don't mention `automatically' in addition to `generated'.

12006 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12008 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12009 * bin/autoupdate.in: Ditto.
12010 * bin/autoheader.in: Reworded a few comments.
12011 * bin/autoconf.in: Reworded help text for a few options.

12015 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12017 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12018 already have $file). Set output files to binary mode (helps avoid
12019 CR issues on DOSish systems).
12021 2001-09-19 Akim Demaille <akim@epita.fr>
12023 * lib/autotest/general.m4: Englishoes.
12024 From Tim Van Holder and Alexey Mahotkin.
12026 2001-09-18 Paul Eggert <eggert@twinsun.com>
12028 * doc/autoconf.texi (Common Shell Constructs): New node,
12029 documenting AS_DIRNAME.
12030 (Limitations of Usual Tools): Refer to it when discussing dirname.
12031 Also, update discussion of POSIX standard to reflect latest draft.
12033 * lib/autoconf/c.m4:
12034 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12036 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12037 Do not pass a first argument with leading '-'
12038 to expr, by parenthesizing initial integers that might be negative.
12040 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12041 now merely checks whether it is an error to pass an argument
12044 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12045 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12046 whether it is a (compile-time) error to pass an argument to
12047 getpgrp. This simpler test supports the revised documentation,
12048 and is all that AC_FUNC_GETPGRP's users really need.
12050 2001-09-18 Akim Demaille <akim@epita.fr>
12052 * doc/autoconf.texi (Limitations of Make) <$<>: New.

12060 2001-09-18 Paul Wagland <paul@wagland.net>
12062 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12064 Add test for AS_BASENAME.
12065 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12066 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12067 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12068 * tests/base.at: Fixed the expected responses. The old ones were
12070 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12071 the documentation claims it should (and how it behaved in 2.13).
12073 2001-09-18 Akim Demaille <akim@epita.fr>
12075 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12076 the AC_CONFIG_COMMANDS invocation.
12077 This also solves the name clash problems.
12078 Don't set the package's ID.
12079 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12080 No longer to be shipped.
12081 (version.in): Remove.
12082 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12083 * lib/autoconf/status.m4: Adjust.
12084 Use `m4_PACKAGE_STRING'.
12085 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12086 the only optional argument is the name of the test suite.
12087 Expect `package.m4' to define the package signature.
12088 * lib/autom4te.in (Autotest): Add `package.m4?'.
12089 * tests/Makefile.am (package.m4): New.
12090 * tests/suite.at: ifnames is a victim.
12092 2001-09-18 Akim Demaille <akim@epita.fr>
12094 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12095 AC_LIBSOURCE, AC_CONFIG_FILES.
12096 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12097 program version string doesn't match the package's.
12098 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12101 2001-09-17 Paul Eggert <eggert@twinsun.com>
12103 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12104 Allow expression to return any value that can fit into unsigned long
12105 (not int, as before). Check for output errors.

12109 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12110 Always include <stdio.h> and <stdlib.h>. Evaluate
12111 the expression in an extra function before these includes. Call
12112 fprintf "%d" only after ensuring the argument is of type 'int'.
12113 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12115 2001-09-17 Paul Eggert <eggert@twinsun.com>
12117 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12118 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12119 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12120 when they don't exist.
12122 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12123 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12126 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12127 version with the version used by fileutils 4.1, except use
12128 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12131 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12133 2001-09-13 Akim Demaille <akim@epita.fr>

12173 * lib/autotest/general.m4 (AT_INIT): Create and remove
12174 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12175 test suites can cohabit.
12177 2001-09-13 Akim Demaille <akim@epita.fr>
12179 * tests/mktests.sh: Don't output banners for empty test files.

12231 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12234 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

12278 to avoid GCC warnings.
12281 2001-09-05 Akim Demaille <akim@epita.fr>

12285 2001-09-05 Akim Demaille <akim@epita.fr>
12287 Be ready to handle filenames as stupid as `dnl.at', for if even
12288 the maintainer is dumb enough to do that...
12290 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12291 excellence in M4 quotation: consider `__file__' is active.
12293 And BTW, when invoking m4, pass the --include in the right order:

12374 * man/Makefile.am (.x.1): We really have to pass
12375 autom4te_perllibdir.

12379 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

12386 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12387 Use directly autom4te, not autoconf.

12445 There is no such envvar since the inception of autom4te.cfg.

12467 * lib/Autom4te/General.pm (&find_peer): Remove.
12468 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12469 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12470 * man/Makefile.am: Let help2man rely on PATH instead of trying to

12970 2001-08-15 Akim Demaille <akim@epita.fr>
12972 * bin/autom4te.in (@m4_warning): New.
12973 (&handle_m4): Use it.
12974 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

12977 is in the src tree.
12979 2001-08-15 Akim Demaille <akim@epita.fr>

13054 magic values from an object file when cross-compiling.
13055 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13057 2001-08-10 Akim Demaille <akim@epita.fr>
13059 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13061 Suggested by Russ Allbery.
13063 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13065 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13066 current $prefix to the sub-configures.
13068 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13070 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13071 extension (needed on BeOS). Reported by Guido van Rossum.
13073 2001-08-09 Akim Demaille <akim@epita.fr>
13075 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13077 2001-08-07 Akim Demaille <akim@epita.fr>
13079 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13081 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13082 No need to remove the files before and after the each test, before
13083 each test and at the end of the suite is enough.
13084 Display only the children `times', not the shell's.
13085 If the test failed or was skipped, at-times is not available.
13087 2001-08-07 Akim Demaille <akim@epita.fr>
13089 Always produce testsuite.log, including when there are no
13090 failures. This helps getting information on skipped tests, and
13091 duration of the tests. Err, implement the latter btw.
13093 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13094 Dump information on the first run of each test.
13095 (AT_CLEANUP): Create `at-times' containing the duration of the
13098 2001-08-07 Akim Demaille <akim@epita.fr>
13100 The use of `dumpstat' revealed that `len' was used although it
13101 should not. m4_text_wrap was using it, but in the Autoconf world
13102 where it is legal. Hence (i) test M4sh in its own world, not
13103 Autoconf's, and (ii), ahem, fix the bug :)
13105 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13106 does not like `' instead of [].
13107 (AT_INIT): Forbid `^_?AT_'.
13108 And don't output such tokens.
13109 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13110 `script.as', and `autom4te.cache'.
13111 Remove `empty' and `macro' which are no longer used.
13112 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13113 * tests/m4sugar.at: Use it.
13114 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13116 2001-08-07 Akim Demaille <akim@epita.fr>
13118 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13120 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13122 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13124 2001-08-04 Akim Demaille <akim@epita.fr>
13126 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13127 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13129 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13130 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13131 (AC_F77_MAIN): Likewise.
13133 2001-08-04 Akim Demaille <akim@epita.fr>
13135 Don't rely on M4sugar outputting the patterns in files, since we
13136 might process the output _without_ running m4, hence without these
13139 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13140 * bin/autom4te.in (@Request::includes): Remove, unused.
13141 (@Request::source): Rename as...
13142 (@Request::input): this.
13143 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13144 (&handle_output): Fetch the patterns from the traces.
13145 `$forbidden' and `$allowed' are constant: use m//o.
13146 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13147 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13149 2001-08-04 Akim Demaille <akim@epita.fr>
13151 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13152 autoconf', i.e., in addition to caching traces, cache the output.
13154 * bin/autom4te.in (Request::cache): Rename as...
13155 (Request::id): this.
13156 ($cache, $icache, $tcache, $ocache): New.
13157 (&handle_m4): Save M4 output in the cache instead of $tmp.
13158 (&handle_output): Adjust.
13159 (&up_to_date_p): Check that the output cache is up to date too.
13160 (top level): Run `&handle_m4' iff force or the cache is invalid.
13161 Run `&handle_output' if the output cache is more recent.
13163 2001-08-04 Akim Demaille <akim@epita.fr>
13165 * bin/autom4te.in ($force): New.
13166 (&parse_args, &print_usage): -f, --force is a new option.
13167 (&handle_output): CPP directives might have spaces after `#'.
13168 (&parse_args): The first file only can be frozen.
13170 2001-08-04 Akim Demaille <akim@epita.fr>
13172 Don't let autom4te compute the `include' traces several times:
13173 first check that the trace cache file is up to date, and then
13174 compare its timestamp with that of the output.
13176 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13177 the preamble. Don't require 5.005 as Autom4te::General does it,
13178 and better yet (use `use', not `require'!).
13179 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13180 Class::Struct as Autom4te::Struct.
13181 * lib/Autom4te/General.pm (File::stat): Use it.
13182 (&mtime): New, export it.
13183 * bin/autom4te.in: Use it.
13184 Declare `$req' is invalid if it is outdated.
13185 Don't declare it valid before saving it if something went wrong.
13187 2001-08-04 Akim Demaille <akim@epita.fr>
13189 Autom4te shall not encode Autoconf data, and preselecting traces
13190 must be proposed to the users.
13192 * bin/autom4te.in (@required_trace): Remove.
13194 (&parse_args, &print_usage): -p, --preselect is a new option.
13195 (&up_to_date_p): Adjust.

13198 2001-08-04 Akim Demaille <akim@epita.fr>
13200 * tests/tools.at (autoconf --trace: user macros): Check traces on
13201 macros invoked without arguments, and macros invoked with multiple
13204 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

13209 2001-08-03 Akim Demaille <akim@epita.fr>
13211 * bin/autoconf.in ($@): Work around the usual sh bug.
13214 2001-08-03 Akim Demaille <akim@epita.fr>
13216 Clean up the handling of the M4 builtins tracing exception.
13218 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13220 (@m4_builtins): Rename as...
13221 (@m4_builtin): this.
13222 (%m4_builtin_alternate_name): New.
13223 (&parse_args): Complete the trace requests with alternate names.

13229 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13230 m4_if, and m4_wrap.
13232 2001-08-03 Akim Demaille <akim@epita.fr>
13234 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13235 (m4_divert_pop): Dump the whole diversion stack when a diversion
13237 * bin/autom4te.in (&handle_output): Remember of the first
13238 occurrence of a possibly undefined macro, not the last.
13239 Complain about the possibly undefined macros in the same order as
13240 the appear in the output.
13241 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13242 * tests/tools.at (autoconf: forbidden tokens, basic)
13243 (autoconf: forbidden tokens, exceptions): No longer sort
13244 autoconf's stderr, as it is now deterministic.
13245 Check that `dnl' is caught.
13247 2001-08-01 Akim Demaille <akim@epita.fr>
13249 * configure.ac: Bump to 2.52c.
13251 2001-08-01 Akim Demaille <akim@epita.fr>

13261 2001-08-01 Akim Demaille <akim@epita.fr>
13263 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
13266 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13267 `END', as `Autom4te::General::END' will be triggered.
13268 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
13269 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
13270 system to run `mv', `rm', and `cmp'.
13272 2001-08-01 Akim Demaille <akim@epita.fr>
13274 * lib/Autom4te/General.pm (&unique): New.
