3 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
4 AC_CHECK_TYPE, AC_CHECK_TYPES.
5 * doc/autoconf.texi (Generic types): C types must be type-names
6 (the C terminology), not type-ids (the C++ term). C++ types
8 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
9 for C++; this drops support for anonymous struct and union types,
10 which were problematic anyway.
11 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
14 2007-04-12 Jim Meyering <jim@meyering.net>
16 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".
18 2007-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
20 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
21 to prefer a link source from the build tree, if it exists.

26 * doc/autoconf.texi (Generic Types): Document the restrictions
27 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
28 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
29 with objects too. Document the restrictions on its use.
30 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
31 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
32 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
33 works but the latter doesn't, then it's a valid type.
34 This lets people use function types and so forth.
35 For C++ there doesn't seem to be a simple solution, so leave it alone.
36 (AC_CHECK_SIZEOF): Allow argument to be a variable.
37 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
38 AC_CHECK_TYPE; that wasn't documented or necessary.
40 2007-04-11 Stepan Kasal <kasal@ucw.cz>
42 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
45 2007-04-11 Stepan Kasal <kasal@ucw.cz>

59 * NEWS: Document this.
61 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
63 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
64 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
65 default still has the problem. Problem reported by Bruce Korb.

83 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
85 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
86 checks for unsigned long long int.
88 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
90 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
91 nonstandard grep R.E. escape sequences.
93 2007-03-17 Jim Meyering <jim@meyering.net>
95 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
96 (Limitations of Usual Tools): Also list \< and \>, and mention that
97 HP-UX's grep, like the one from Solaris, does not support that syntax.
99 2007-03-09 Stepan Kasal <kasal@ucw.cz>
101 * doc/autoconf.texi (Specifying Names): `--host' does not
102 change the build type.
104 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
106 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
107 suggests AC_CONFIG_HEADERS.
108 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
109 AC_CONFIG_HEADERS. Problem reported by
112 2007-02-28 Paul Eggert <eggert@cs.ucla.edu>

116 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
117 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
118 universal binaries. Problem reported by Elias Pipping.
120 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
122 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
123 * doc/autoconf.texi (C Compiler): Document this. There is a new
124 extra argument ACTION-IF-UNIVERSAL.
125 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
126 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
127 Reindent for sanity's sake.
129 2007-02-24 Eric Blake <ebb9@byu.net>
131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

162 with traditional Awk and begin.
163 * tests/torture.at (Limitations of Builtins): Document the problem
164 with Bash 2.03 printf.

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

208 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
209 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
210 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
211 substitution will still be done by the special code.
212 Report by Jim Meyering.
214 * doc/autoconf.texi (File System Conventions): Mention that
215 $PATH_SEPARATOR is for the build system only.
216 Report by Keith Marshall.
218 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
220 * doc/autoconf.texi (Setting Output Variables): Mention that
221 all non-NUL characters are ok in substituted values.
222 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
223 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
224 carriage return for $AWK, needed for BSD awk.
225 * tests/torture.at (Substitute and define special characters):
226 Test all 8 bit non-NUL characters.
227 Report against Automake by Patrick Welche.

231 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
233 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
235 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
236 early on the reader side, drop stderr of the input to avoid
237 `broken pipe' error output; this may happen even with shell
238 builtin `echo' of some bash versions. Reports by Ian Macdonald
239 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
241 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
243 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
244 separate items of `ac_user_opts', to avoid long lines.
245 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
247 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
249 * doc/autoconf.texi: Fix some typos.
251 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
253 Fix some wording problems noted by Paolo Bonzini in:
254 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
255 * doc/autoconf.texi (Signed Overflow Examples): Give more
256 discussion about the allow_superuser_privileges example,
257 and change it a bit to make things clearer.
258 (Optimization and Wraparound): Clarify whether the compiler
259 will generate an infinite loop for the example derived from
260 Autoconf's mktime test.
261 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
262 Also, clarify unsigned multiplication overflow.
264 2007-01-04 Eric Blake <ebb9@byu.net>
266 * bin/Makefile.am (RELEASE_YEAR): New macro.
267 (edit): Use it to supply correct copyright year to scripts.
268 * bin/autoconf.as (version): Use it.
269 * bin/autoheader.in ($version): Likewise.
270 * bin/autom4te.in ($version): Likewise.
271 * bin/autoreconf.in ($version): Likewise.
272 * bin/autoscan.in ($version): Likewise.
273 * bin/autoupdate.in ($version): Likewise.
274 * bin/ifnames.in ($version): Likewise.
276 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
278 * doc/autoconf.texi (Integer Overflow): Revised based on today's
279 feedback. The most important changes document what happens when
280 you convert an out-of-range value to a signed integer type, and
281 say that (sum < a) != (b < 0) reliably detects overflow when sum =
284 * doc/autoconf.texi (Integer Overflow): Greatly expand and
285 rewrite, taking notions from the recent discussion on the gcc and
286 autoconf mailing lists; please see
287 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
288 and follow the many links.
289 (Integer Overflow Basics, Signed Overflow Examples):
290 (Optimization and Wraparound, Signed Overflow Advice):
291 (Signed Integer Division): New sections.
293 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
295 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
296 preprocessor macro arguments in traced name.
297 * doc/autoconf.texi (Defining symbols): Document longstanding
298 support for AC_DEFINE-ing macros with arguments, and document
299 behavior when the same variable has multiple AC_DEFINEs.
300 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
301 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
302 macros directly, giving much shorter and simpler code.
304 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
306 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
307 space before "$ac_configure_args" to prevent a 'config.status
308 --recheck' failure if ac_configure_args doesn't contain a leading
309 space. This works around a problem with the XEmacs configure.ac,
310 which uses the (undocumented) ac_configure_args variable
311 inconsistently with Autoconf.
313 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
315 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
316 Include <limits.h>, and use its INT_MAX to rewrite the
317 j loop so that it does not overflow 'int'. Problem reported by
319 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
320 Play it safe by shifting left by 1 rather than multiplying by 2,
321 as GCC is less likely to optimize this away when the value
322 is signed (when it assumes overflow leads to undefined behavior).
323 Also, don't assume time_t uses two's complement.
325 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
327 * tests/torture.at (Substitute a 2000-byte string): Avoid using
328 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
329 dumps core on it. Report by Tim Rice.
331 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
333 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
334 --disable-option-checking to --help output even when
335 AC_PRESERVE_HELP_ORDER is not used.
336 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
337 --with argument, rather than argument with [-.] replaced by
339 * NEWS: Fix typo in previous change; the news was in the
342 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
344 * NEWS: Warnings are now generated by default for unknown
345 --enable-* and --with-* options.
346 * doc/autoconf.texi (Option Checking): Renamed from
347 (Configure Option Checking). Tighten up the wording a bit.
348 (External Software, Package Options): Cross-reference to Option
349 Checking, and use this to shorten our section.
350 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
351 "$x" to test "x$foo" != x.
352 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
353 Don't warn if $enable_option_checking is "no".
354 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
355 ac_unrecognized_opts to the empty string.
356 Don't echo the unrecognized opts, as this might mishandle
357 backslashes or leading -.
358 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
359 usage next to the other --disable-FEATURE options in the
362 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
364 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
365 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
366 Print warning for unrecognized --with and --enable options
367 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
368 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
369 Disable option checking when subdirs are configured.
370 (AC_OUTPUT): If warnings are enabled, print warning about
371 unrecognized --with and --enable options at the end of
372 the configure output (as well as at the beginning).
373 * doc/autoconf.texi (Option Checking): New node.
374 Document new option warning functionality.
376 2006-12-16 Eric Blake <ebb9@byu.net>
378 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
379 * NEWS: Start news for current version.
381 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
383 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
384 Define HAVE_GETMNTENT to 1, not to the empty string.
385 Problem originally reported by Jochen Friedrich in
386 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
388 This change prompted by a problem report by Andrey Simonenko in
389 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
390 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
391 object-like macros only, in the traditional portable character
393 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
394 Warn about attempts to define things that are not identifiers.
395 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
396 awful hack that AC_DEFINEd macro names containing parentheses.
398 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
400 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
401 too drastic, even if Texinfo in theory requires it for info mode.
403 (config.status Invocation): Renamed back from Recreating a
405 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
406 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
408 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
410 * NEWS: Version 2.61a.
412 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
413 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
415 * NEWS: Document changes with echo and printf, and the lack
416 of limits on the total size of multi-line values of substituted
417 variables, and the AC_FUNC_FSEEKO fix.
419 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
421 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
422 Writing configure.ac.
423 (Autoconf Input Layout): Renamed from configure.ac Layout.
424 (Recreating a Configuration): Renamed from config.status Invocation.
425 (Obsolete Recreation): Renamed from Obsolete config.status Use.
426 (acconfig Header): Renamed from acconfig.h.
427 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
428 (Writing Testsuites): Renamed from Writing testsuite.at.
429 (Autom4te Cache): Renamed from autom4te.cache.
431 * BUGS: Remove mention of VPATH problem, since it's now documented
432 not to be a bug in the Autoconf build procedure itself, but rather
433 a problem with the proprietary `make' programs.
435 * doc/autoconf.texi (Build Directories): Add a cross reference
438 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
439 * doc/standards.texi: Sync from gnulib.
441 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
442 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
443 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
444 generated automatically.
446 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
448 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
449 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
450 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
452 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
454 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
455 `CEOF$ac_eof' special marker, the awk script cannot contain a
456 line matching `^CEOF', so this is not needed any more.
457 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
458 special marker in the test.
460 2006-12-06 Stepan Kasal <kasal@ucw.cz>
462 * tests/tools.at (autom4te preselections): Use `find -newer';
463 remove one of the sleeps.
465 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
466 more readable, using ...
467 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
469 * doc/autoconf.texi (autoheader Invocation): Do not double-
470 quote the parameter of `AH_BOTTOM' in the example.
472 2006-12-05 Stepan Kasal <kasal@ucw.cz>
474 * doc/autoconf.texi (Configuration Headers): Remove the
475 example with multiple input files.
476 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
477 multiple input files.
479 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
481 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
482 creating the awk substitution script, handle one input line at a
483 time, so that the maximum length of a substituted (multi-line)
484 value is not limited by the size of the sed pattern space.
485 The trade-off is a slightly repetitive sed script.
486 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
487 can only have up to 7 characters, due to Solaris 10 /bin/sed.
488 * tests/torture.at (Substitute a 2000-byte string): Increase the
489 test with several long lines, they should not be caught by sed
492 * tests/tools.at (autom4te preselections): New test, to flag
493 entries missing from autom4te.cfg.
494 Report by David Byron <dbyron@hheld.com>.
496 * tests/torture.at (Substitute a 2000-byte string): Actually use
497 AC_PROG_AWK, so the last change works as intended.
498 (Substitute and define special characters): Likewise.
499 (Substitute a newline): Likewise.
501 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
502 instead of `awk' consistently.
503 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
504 * tests/torture.at (Torturing config.status): Test both the
505 result of AC_PROG_AWK and plain awk.

512 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
513 can be assigned to a function pointer. Problem reported by
514 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
515 part of a patch by Ralf Wildenhues in that same bug report.
517 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
519 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
520 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
522 2006-12-01 Eric Blake <ebb9@byu.net>
524 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
525 cross-compiling from cygwin to mingw.
526 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
527 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
528 to lib/autoconf/c.m4.
530 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
532 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
533 string for more reliable failure. Wrap the entire test that
534 causes the broken Solaris printf to dump core, in a subshell,
535 so the segmentation fault message is reliably suppressed.
536 Fix shell expansion errors by using /usr/ucb/echo always;
537 avoid an error on systems without it by another subshell.
538 Avoid m4 expansion of `$1'. Set the zeroth argument of the
539 subshell-$as_echo to `as_echo', for better error message.
541 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

544 `BASH_SOURCE' contain a newline, set them to empty, as they may
547 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
549 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
550 years and is too hard to maintain now. The last straw was
551 reported by Jerker Baeck in
552 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
553 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
554 * doc/autoconf.texi (Particular Functions): Move
555 AC_FUNC_SETVBUF_REVERSED from here...
556 (Obsolete Macros): ... to here. Say that it does nothing now.
557 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
558 Turn into (almost) a no-op.
560 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
562 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
563 These macros are obsolescent and new applications shouldn't need them.

579 so that it's also present in the output file. Standardize wording
580 in makefile copyright notices to match GNU coding standards.

594 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
596 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
597 in the sed script that mangles the awk script: delete up to the
598 first exclamation mark only.
599 * tests/torture.at (Substitute and define special characters):
602 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
604 Rewrite config files generation: avoid quadratic growth in
605 the number of substituted variables by using awk instead of sed
606 for the bulk of the substitutions.
607 * NEWS: Mention this.
608 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
609 forbidden in the output (and thus input) file.
610 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
611 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
612 generate just one large awk script for substitutions,
613 eliminating much of the earlier complexity, while adding some
614 new complexity. Only expand the substitution templates at
615 configure time, for smaller configure script size. If
616 _AC_SUBST_FILES are used, test 'awk' for working getline support
617 at config.status time. If absent, interpolate through the
618 shell. The awk script was written with much help
619 from Paolo Bonzini and Paul Eggert.
620 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
621 (_AC_SED_FRAG_NUM): Likewise.

625 * tests/torture.at (Substitute a 2000-byte string): Also
626 substitute a line with 1000 words, and a variable with several
628 (Substitute and define special characters): Test awk special
629 characters, and put substitution input strings `@foo@' in the
630 output, to test that no recursion happens; test several other
631 combinations from Paolo Bonzini.
633 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
635 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
636 that replaced echo with AS_ECHO where this wasn't necessary.
637 Problem reportd by Ralf Wildenhues.
638 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
639 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
640 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
642 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
644 * lib/freeze.mk (GREP): Removed, no need to initialize this.
646 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
648 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
649 that traditional Awk lacks 3-arg "split". It has it.
650 Mention that FS must be a single character, and a few other
651 99-byte limits of traditional Awk.
652 Mention that if (i in a) doesn't work with traditional Awk.

658 (Newline-CODE-BS-newline in command):
659 (Single-quote-BS-newline in command):
660 (Single-quote-newline-BS-newline in command):
661 Use printf '%s\n' instead of echo, for portability to hosts
662 where echo interprets backslashes. This will break on hosts
663 that lack printf, but for now let's assume all such hosts
664 are dead (if not, we should get reports of test failures).
666 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
668 'echo' has some portability problems, when given a first argument
669 with a leading '-', or when given any argument containing '\'.
670 Avoid using 'echo' in these cases.

707 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
708 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
709 bug, but we might as well stop using ECHO_N and ECHO_C internally.
710 * lib/autotest/general.m4 (AT_SETUP): Likewise.

730 * configure.ac (AC_INIT): Bump to 2.61.

860 Single-quote in a test title,
861 Double-quote in a test title): Don't expect failure anymore.
862 (Backslash in a test title): Put a non-whitespace character after the
863 backslash so that Bourne shells might actually see it as an escape
865 (Brackets in a test title,
866 Pound in a test title,
867 Comma in a test title,

886 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build

924 reported by Nelson H. F. Beebe for Coreutils 6.4.
926 * tests/tools.at (autoconf --trace: user macros): Remove test
927 for tracing multiline macros, since m4 1.4.7a uses a different
928 way to number lines. Problem reported by Ralf Wildenhues.

990 looking for special shell characters.

1006 (Imported from Automake.)
1007 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1008 which incorrectly sets the mode of an existing destination
1009 directory. In some cases the unpatched install-sh could do the
1010 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1011 system. We hope this is rare in practice, but it's clearly worth
1012 fixing. Problem reported by Alex Unleashed in
1013 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1014 Also, don't bother to check for -m bugs unless we're using -m;
1015 suggested by Stepan Kasal.

1069 include the default headers, and redefine obstack_chunk_alloc
1070 and obstack_chunk_free. Fixes false failure with glibc.

1093 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1094 Use a better substitute, by inspecting the output of "ls"
1095 rather than just using ":".
1096 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1097 rather than AS_EXECUTABLE_P, since we needn't worry about
1098 non-regular files here.
1100 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1101 due to configuration hassles with this. See Tonya Underwood's report

1125 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1126 comment about ac_cpp_err; it was incorrect, and anyway
1127 ac_cpp_err is being removed below.
1128 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1129 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1130 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1132 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1133 with werror_flag and conftest.err and so forth. This is more
1134 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1135 and anyway the user shouldn't normally want to see this gorp logged.
1136 Problem reported by Ralf Wildenhues.
1137 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1138 empty, not 'no', since the rest of the code uses 'test -z'.

1142 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

1146 Problem reported by mwoehlke in
1147 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1149 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1150 than creating a file to use with test -x; this is much faster.
1152 2006-10-02 Bruno Haible <bruno@clisp.org>
1154 * lib/autom4te.in (Automake-preselections): Add

1164 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

1166 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1167 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1168 still doesn't let the program compile.
1169 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1172 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1173 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1174 include it, without including anything else.

1182 `error.h', and include it, for a `error_at_line' prototype.
1183 Use a nonempty format string in the link test.
1184 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1185 for a declaration of wait3.

1191 can apply to constants too, and that it checks for macro defns.
1192 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

1194 values. Problem reported by Ralf Wildenhues.

1409 broken lex libraries like native ia64-hp-hpux11.22; see
1410 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

1539 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1540 -Wundef -Werror". Problem reported by David Fang in
1541 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

1564 problems with arg script text that doesn't end in newline, and

1601 less skeptical about "volatile", after discussion with
1602 Bruno Haible on bug-gnulib.
1603 (Limitations of Usual Tools): Warn about sed stripping
1604 leading white space from text. From Bruno Haible.
1606 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1608 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1609 compiler complains about it, even if things works after the
1610 complaint. Problem reported by Peter O'Gorman.

1616 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1618 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1631 under AC_C_VOLATILE.
1632 (Volatile Objects): Be a little less skeptical about what
1633 "volatile" means. Derived from thoughts by Ben Pfaff in
1634 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1636 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1640 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1642 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1643 more globally, since the 2006-06-30 patch didn't suffice. Problem
1644 reported by Keith Marshall. Also, don't bother with builddir2,
1645 since it shouldn't be needed any more.
1647 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1649 * doc/autoconf.texi (Generic compiler characteristics):
1650 Document AC_COMPUTE_INT. Fix wrong statements on Default

1664 * NEWS: Document previous change.
1666 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1668 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1669 Require that long long int be at least 64 bits wide. C99 requires
1670 this and enough programs depend on it so we should check for it.
1671 Bruno Haible reports in
1672 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1673 that long long int is 32 bits wide with some nonstandard compilers.
1674 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1676 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1678 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1679 to a nonexistent file, so that we don't have to worry about
1680 a local site configuration that doesn't use /usr/local.
1681 Problem reported by Keith Marshall in
1682 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1684 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1686 * doc/autoconf.texi: Be more consistent about using @acronym with
1687 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1688 quite right (it talked about "OSF/Tru64", even though the
1689 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1690 and it even mentioned "OSF 4"!) and at this point there's little
1691 reason to talk about OSF any more, since it died in 1994.
1692 (Specific Compiler Characteristics): Simplify example of
1693 negative-size array.
1694 (File Descriptors): Reorder to make the text flow better.
1695 Remove joke about "appreciate the various levels"; I didn't get it.
1696 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1697 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1698 (File Descriptors, Limitations of Usual Tools):
1699 Tone down the advice against renaming or removing open files.
1700 (Limitations of Usual Tools): Add a new section, on 'rm'.
1702 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1704 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1705 -lXt in LIBS, idea from Karsten Hopp; this was due since
1708 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1709 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1710 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1711 (which belong to Xt, not X itself). See Debian bug 327655.
1713 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1715 * configure.ac (AC_INIT): Bump to 2.60a.

1735 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1737 * doc/autoconf.texi (Changed Directory Variables): New node,
1738 to document the whole `datarootdir' business a bit better.
1740 * tests/torture.at (datarootdir workaround): Extend test.
1741 Prompted by report by Alexandre Julliard.
1743 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1745 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1746 when using default mode of IBM C 6 for AIX. Problem and two-line
1747 fix reported by Larry Jones.
1749 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1751 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1752 about literal '${datarootdir}' if a definition is found in the
1755 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1757 * NEWS: Use "M4" rather than "m4" when appropriate.
1758 Problem reported by Eric Blake.
1759 * doc/autoconf.texi: Likewise.
1760 Use @acronym around BSD, GCC, and GNU when appropriate.
1761 (Why GNU M4): Renamed from "Why GNU m4".
1762 (Redefined M4 Macros): Mention that Posix
1763 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1764 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1767 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 * bin/autom4te.in (handle_output): Do not forbid the empty
1771 * tests/tools.at (autoconf: the empty token): New test.
1773 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1775 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1776 calls, so that we do not care whether they are LIFO or FIFO;
1777 in the m4_wrap, do not check which diversion is the topmost
1778 one, just check that the stack is balanced at the end.
1779 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1780 base diversion forever--pop the previous diversion before
1781 opening the new one; consequently, remove the m4_wrap call.
1782 * lib/autotest/general.m4 (AT_INIT): Likewise.
1783 * tests/m4sugar.at: Do not use
1784 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1786 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1787 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1789 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1790 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1791 Rework example of m4wrap token-pasting trouble so that it doesn't
1792 care whether it's LIFO or FIFO.
1793 Fix some "contrary to"s that are awkward in English.
1795 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1797 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1798 to `yes' instead of `int$1_t' if the type is found, for more
1799 consistent configure output (where $1 is the number of bits).
1800 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1801 Suggested by Bruno Haible.
1803 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1804 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1805 with system headers. Report by Bruno Haible.
1807 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1809 * config/config.guess, config/config.sub: Sync from upstream.
1811 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1812 in order to avoid picking up an older installed frozen m4sh.m4f.
1813 Besides an outdated shell startup, this could have been created
1814 by an earlier M4 version with incompatible frozen file format.
1816 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1818 * README: Recommend m4 1.4.4 instead of 1.4.3..
1819 * doc/autoconf.texi: Likewise.
1820 (Special Chars in Names): Say that $(.FOO) is portable, as
1821 suggested by Stepan Kasal.
1822 (Installation Directory Variables, Build Directories):
1823 (Automatic Remaking, Subdirectories, Fortran Compiler):
1824 (Making testsuite Scripts, Defining Directories):
1825 Quote variable usages better.
1826 (Making testsuite Scripts): Add clean-local rule to makefile
1827 snippet, by Eric Blake.
1828 (Installation Directory Variables): Fix table item font.
1829 Reword slightly to clarify. Generalize advice about
1830 not using special characters to include all file-related
1831 vars, not just VPATH.
1832 (Special Chars in Variables): Warn about special characters in
1834 (Assignments): Clarify default-value example as suggested by
1836 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1837 (Special Shell Variables): Note leading ./ or ../, as suggested
1839 (Limitations of Builtins): Under cd, warn about CDPATH.
1840 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1843 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1845 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1846 `@var', for texi2html.
1847 (Systemology): Some more word wrapping, for DVI output.
1848 (autom4te Invocation): The short option for `--melt' is `-M',
1851 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1853 * doc/autoconf.texi: More formatting and English tweaks,
1854 many suggested by Ralf Wildenhues.
1855 Reword to avoid "@code{...}'s" and the like, since it's ugly
1856 with Emacs info mode. discontents -> woes.
1857 Put a few "will"s back. time stamp -> timestamp.
1858 side-effect -> side effect.
1860 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1862 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1863 Warn about $@ not persisting. Problem reported by Julien Danjou in
1864 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1865 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1866 Mention other special chars, too.
1868 2006-06-14 Eric Blake <ebb9@byu.net>
1870 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1872 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1874 * doc/autoconf.texi: Some systematic minor improvements, as
1875 follows. Use "makefile" when talking about makefiles
1876 generally (which might be named "makefile" or "Makefile" or even
1877 "foo.mk"), "Makefile" when talking about a specific makefile
1878 called "Makefile". This unclutters the text from weird quotes
1879 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1880 values" rather than "@var{foo}s" and similar constructs containing
1881 "}s". Use "Make rules" rather than "Makefile rules". Minor
1882 English-language improvements. Change the prefix "sub-" to "sub"
1884 Put blank lines around examples more consistently.
1885 Avoid "rather" and "very" as intensifiers.
1886 Avoid "will" as an auxiliary.
1887 (Limitations of Make): Split this node into....
1888 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1889 (Leading _ in Macro Names, Backslash-Newline-Newline):
1890 (Backslash-Newline Comments, Long Lines in Makefiles):
1891 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1892 (obj/ and Make, make -k Status, VPATH and Make):
1893 (VPATH and Double-colon, $< in Explicit Rules):
1894 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1895 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1896 New nodes, resulting from splitup of Limitations of Make.
1897 All cross-references changed. Raise the top node from
1898 a section to a chapter, and all subnodes accordingly.
1899 Redo the introductory wording to match the new organization.
1900 (Installation Directory Variables): Use an example that is
1901 closer to what Autoconf actually does. Mention that VPATH's
1902 value should not contain metacharacters or white space.
1903 (Fortran Compiler): Fix a VPATH bug in an example.
1904 (Leading _ in Macro Names): Mention that this problem is no longer
1905 of practical concern.
1906 (VPATH and Make): Reword the advice to make it clearer
1907 that Autoconf and Automake support VPATH in non-GNU make, but
1908 many packages have bugs in this area.
1909 ($< in Explicit Rules): Refer to Build Directories rather
1910 than using a (non-VPATH-safe) example.
1911 (Automatic Rule Rewriting): Mention the sort of disaster that
1912 can ensue with Solaris-style rule rewriting with VPATH.
1914 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1916 * doc/install.texi (Compilers and Options): Weaken the
1917 suggestion to use GNU make for VPATH builds.
1919 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1920 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1922 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1923 in regular expression.

1927 * doc/autoconf.texi (Installation Directory Variables):
1928 Drop extra @samp from `@table @samp' item.
1929 (Limitations of Usual Tools): Comment fix.
1930 Do not nest @samp just to point to other table items.
1931 (Writing testsuite.at) <AT_CHECK>: The second argument to
1932 `@dvar' is already @samp'ed.
1933 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1934 do not use @var in the second argument.
1936 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1938 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1939 $as_shell.exe too. Problem reported by Andreas Buening in
1940 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1942 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1944 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1945 `unused variable' compiler warning, for `-Wall -Werror'.
1946 Reported by Jaap Haitsma in
1947 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1949 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1951 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1952 case the compiler dumps core. Problem reported for
1953 OpenServer 5.0.7 by Tim Rice in
1954 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1955 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1958 2006-06-06 Tim Rice <tim@multitalents.net>.
1960 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1961 "ERROR" only shows up in "make check" output if there is an
1964 2006-06-06 Eric Blake <ebb9@byu.net>
1966 * tests/tools.at (automatically allowed tokens): Fix typo.
1968 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1970 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1972 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1973 typically overflows on x86 CPUs, even though the C standard
1976 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1978 * configure.ac (AC_INIT): Bump to 2.59e.
1981 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1985 * config/texinfo.tex: Sync from upstream.
1987 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1988 seen, invoke libtoolize with `--ltdl' argument.
1989 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1991 Suggested by Eric Blake.
1993 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1995 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1996 reported by Ralf Wildenhues.
1997 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1999 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2003 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2005 * doc/autoconf.texi: Modernize some of the references to Solaris.
2007 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2009 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2010 message issued by AC_REQUIRE.
2011 * tests/m4sugar.at: Check m4_require's error message.
2012 * tests/base.at: Check AC_REQUIRE's error message.
2013 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2015 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2017 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2018 `expout' as the last parameter.
2019 * tests/tools.at: Adapt to the above change.
2021 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2023 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2024 information about race-free implementations of mkdir.
2026 2006-06-04 Eric Blake <ebb9@byu.net>

2029 * bin/autoconf.as (Usage): Likewise.
2030 * bin/autom4te.in (help): Likewise.
2031 * doc/autoconf.texi (autom4te Invocation): Likewise.
2033 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2035 * NEWS: GNU make now recommended for VPATH builds.
2036 Mention that some macros are now documented to be obsolescent.
2037 * doc/autoconf.texi:
2038 Prefer "current" to "modern" to describe
2039 currently-used (albeit perhaps old-fashioned) hosts.
2040 Mention which ancient features no longer need to be worried about.
2041 setgid -> set-group-ID
2042 setuid -> set-user-ID (these are the Posix terms)
2043 Fix some misuses of "only".
2044 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2045 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2046 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

2051 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2052 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2053 Mention that these macros are obsolescent.
2054 (Installation Directory Variables): shall -> should
2055 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2056 Mention that it's now safe to use 3 and 4.
2057 (Limitations of Usual Tools): cp -r is now specified by Posix.
2058 Omit longwinded and obsolescent discussion of cp -f.
2059 Modernize discussion of expr, ls.
2060 (Limitations of Make): Modernize discussion of VPATH builds.
2061 Mention $? as a workaround in some cases.
2062 * doc/install.texi (Basic Installation):
2063 Mention "./configure; make; make install" first. Be more
2064 specific about why this file is generic. Remove unnecessary
2065 parens. Remove misleading "only". Remove obsolete advice
2066 about csh. Don't say "configure" takes awhile; say it
2067 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2068 and CC=c99 rather than CC=c89, as these are blessed by current
2069 Posix. Recommend GNU make if doing a VPATH build.
2071 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2073 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2074 examples involving shell prompts.
2076 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2077 and Paul Eggert <eggert@cs.ucla.edu>
2079 * doc/autoconf.texi (Here-Documents): Add details about the
2080 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2081 use "here-documents" instead of "here documents".
2083 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2085 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2087 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2089 * doc/autoconf.texi (File System Conventions): Warn about ":"
2090 anywhere in directory names.
2092 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2094 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2095 about quoting the case statement, just in case.
2096 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2097 was fixed in ksh93g; reported by Ralf Wildenhues.
2099 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2101 * doc/autoconf.texi (System Services): Do not document
2102 overriding EXEEXT via ac_cv_exeext=ext.
2103 (Particular Programs) <AC_PROG_MKDIR_P>:
2104 Document that ${MKDIR_P} understands --.

2108 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2110 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2111 argument with leading hyphen. Problem reported by Paul Eggert.
2113 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2115 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2116 about quoting ac_try: quote all of it, if any of it seems suspicious.
2117 This means we don't have to worry about ${ or sed any more.
2118 Also, double-quote the case statement, to work around misuses via
2119 underquoting as reported by Ralf Wildenhues in
2120 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2121 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2122 undocumented and dangerous macro.
2123 Problem reported by Ralf Wildenhues in
2124 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2126 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2134 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2135 since evidently some packages rely on the old, broken behavior.
2136 Problem reported by Ralf Wildenhues in
2137 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2138 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2139 pre-2006-05-26 definitions, but leave in the comments that
2140 these macros are dangerous and should not be used.
2141 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2142 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2143 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2144 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2145 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2147 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2149 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2150 the use of 'tr', since this is our only use of 'tr'.
2152 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2153 and Paul Eggert <eggert@cs.ucla.edu>
2155 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2156 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2158 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2161 the output file in the `${datarootdir}' test.
2163 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2164 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2166 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2167 mention of `datarootdir' in the input file(s), but literal
2168 `${datarootdir}' in the output file, and we haven't warned yet,
2169 then warn as well: the user may have (erroneously) used
2170 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2171 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2172 * tests/torture.at (datarootdir workaround): Extend this test.
2175 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2176 and Paul Eggert <eggert@cs.ucla.edu>
2178 * doc/autoconf.texi (autoheader Invocation): The first argument to
2179 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2180 alternatives and clear up the language a bit.
2182 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2184 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2185 ac_config_guess, ac_config_sub, ac_configure.
2186 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2187 Fix typo that prevented an unnecessary space from being removed.
2188 Problems reported by Ralf Wildenhues in:
2189 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2191 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2193 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2194 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2195 Don't use the term "thread-safe" to talk about mkdir race
2196 conditions, since the problem is more a process than a thread
2197 issue. Problem reported by Stepan Kasal in:
2198 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2199 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2200 the test for 'install' more closely. Look at MKDIR_P first.
2201 Look in the PATH, and at /opt/sfw/bin.
2202 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2203 Don't bother to try mkdir -p, since we already check mkdir --version;
2204 just look at the version number. (There's no easy way to check
2205 for race-free implementations.)
2206 * tests/tools.at (autoconf: subdirectories): Adjust to above
2207 changes, since MKDIR_P now might end in "/mkdir -p".
2209 * doc/autoconf.texi (autoheader Invocation): Mention that the
2210 first arg of AC_DEFINE_UNQUOTED must be a literal.
2211 Problem reported by Ben Pfaff in
2212 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2214 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2215 * doc/autoconf.texi (Special Chars in Variables): New section.
2216 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2217 (Installation Directory Variables): Quote $(datadir) better.
2218 (Limitations of Builtins): Describe some of eval's trickiness.
2220 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2221 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2222 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2223 in front of every arg, not just trailing args. Quote apostrophes.
2224 (_AC_EVAL_ECHO): New macro.
2225 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2226 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2228 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2229 exposed by quoting of eval argument. Put the command on line line
2231 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2232 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2233 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2234 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2235 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2236 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2237 Use eval more safely.
2238 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2239 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2241 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2242 lines, exposed by quoting of eval argument.
2244 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2245 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2247 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2248 initialization of `ac_cv_exeext', do not override it if it was
2249 already set, unless it was set to `no', for compatibility with
2250 Autoconf-2.13, and comment this.
2251 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2252 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2253 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2254 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2255 Document that this test may be overridden by setting
2258 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2260 Revert these two patches:
2262 2006-04-06 Eric Blake <ebb9@byu.net>
2263 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2264 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2267 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2268 Clean up _AC_COMPILER_EXEEXT* macros.
2269 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2270 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2271 ac_file to the name of the default output file and call
2272 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2273 initial `rm' of the candidate files...
2274 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2275 the same list in subsequent `rm' calls, and for the temporary
2276 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2277 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2278 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2279 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2280 no longer needed) by libtool. Make it a cache check.
2281 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2282 copied here by mistake.
2283 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2284 _AC_COMPILER_EXEEXT.
2285 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2286 _AC_COMPILER_OBJEXT directly.
2287 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2289 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2291 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2292 Fix description of how the buggy `sed' works.
2294 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2298 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2299 ENOLCK. Only mention `make -j' when applicable. Only raise
2300 fatal errors when `make -j' is involved. Improve error message.
2302 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2304 * doc/autoconf.texi (Here-Documents): We now know more about
2305 the variable expansion in here documents bug.
2306 Thanks to Tim Rice and Stepan Kasal.
2308 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2309 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2311 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2313 * tests/autotest.at (Multiline command from M4 expansion):
2314 No failure to be expected if the shell quotes newlines in
2315 commands in the `set -x' output. Report by Tim Rice.
2318 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2320 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2321 expansion in the here-documents used by config.status, as that
2322 runs afoul of the Korn shell version M-12/28/93d bug described in
2323 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2324 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2325 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2327 2006-05-23 Jim Meyering <jim@meyering.net>
2329 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2330 Fix typo introduced with 2006-04-02 change. It reversed the sense
2333 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2335 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2336 ac_dB slightly, to save bytes in the script.
2337 Max out at 50 lines, rather than 96; this is more likely
2338 (though not guaranteed) to avoid obscure 'sed' failures.
2340 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2342 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2343 `tr -d -' as bad option argument. Work around this by deleting
2344 an unrelated character.
2345 Report by Tim Rice <tim@multitalents.net>.
2347 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2348 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2349 Stepan Kasal <kasal@ucw.cz>
2351 * doc/autoconf.texi (Particular Programs): Do not promise that
2352 we always prefer the GNU version of the program, and that we
2353 search according to PATH; both rules can have exceptions.
2354 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2355 AC_PROG_SED. Move descriptions of limitations
2356 to the Limitations of Usual Tools section.
2357 (Limitations of Usual Tools) <sed>: Mention script length
2358 limitations with Solaris /usr/ucb/sed.
2359 <grep>: Fix wording for empty alternative. Mention that -c and
2360 -l should not be combined, and that -E and -F should not be
2363 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2364 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2366 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2367 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2369 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2371 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2372 AC_DEFINE is now passed to m4_pattern_allow.
2373 * NEWS: Mention that; likewise for AC_SUBST.
2374 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2375 the parameter to m4_pattern_allow.
2376 * tests/tools.at: Add a check for that.
2378 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2380 * lib/autoconf/status.m4: Fix typos.
2382 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2384 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2385 only the files that this macro generates.
2387 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2389 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2390 the HP-UX sed limitation of 99 commands, labels do not count.
2391 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2393 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2395 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2397 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2398 Import the following fix from coreutils:
2400 2006-01-13 Jim Meyering <jim@meyering.net>
2402 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2403 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2404 not double-quote uses of that variable, to accommodate the rare
2405 case in which getmntent is available in none of the libraries
2406 checked. This happens at least on FreeBSD 5.0.
2408 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2410 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2411 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2412 some other programs unwisely rely on these undocumented vars.
2413 But put in warning comments about them.
2414 Problem reported by Ralf Wildenhues in
2415 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2416 * NEWS: Document that these variables are intended to go away.
2418 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2420 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2421 and set the language to C++ (analogous to the equivalent Fortran
2424 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2425 * doc/autoconf.texi (C++ Compiler): Document it.
2426 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2429 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2431 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2432 that caused config.status to generate 100-command sed scripts; the
2433 portable limit is 99.
2435 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2437 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2438 variable `ac_d' instead of `d' to avoid infringing namespace.
2439 Report by Ralf Menzel.
2441 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2443 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2444 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2445 * tests/tools.at (autoconf: subdirectories): New test, taken from
2446 the corresponding problem report by Ralf Wildenhues in:
2447 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2449 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2450 Quote some uses of shell variables if they might suffer unexpected
2451 globbing. This doesn't fix all instances of quoting problems that
2452 I found, just the easy ones that look safe.
2453 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2454 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2455 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2456 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2457 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

2464 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2466 * bin/autoreconf.in ($help): Reword according to the manual.
2467 Suggested by Olly Betts.
2469 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2470 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2472 * bin/autoreconf.in: Pass the directory argument to
2473 `require_configure_ac'. Fix comment.
2474 * tests/torture.at (Configuring subdirectories): Expose this.
2475 Reported by Olly Betts.
2477 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2479 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2480 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2481 Automake as follows:
2483 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2484 `$configure_in' instead of `configure.in', to preserve
2485 directory component.
2487 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2489 * config/config.guess, config/config.sub, config/texinfo.tex,
2490 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2492 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2494 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2495 test for C99 conformance; (bool) 0.5 is an integer constant
2496 expression, but (bool) -0.5 is not. Problem reported by Fedor
2497 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2499 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2501 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2502 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2503 Warn about obsolete install-sh files. Remove stray sentence
2504 fragment and fix cross reference.
2505 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2506 install -d; this undoes the 2006-05-10 change.
2507 (MKDIR_P): Mark with AN_MAKEVAR.
2508 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2509 that we don't require $INSTALL to be thread-safe. Move comments
2510 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2511 of AC_PROG_INSTALL. Output a message saying that we're checking
2512 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2513 MKDIR_P instead of AC_SUBST.
2514 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2515 Special magic for MKDIR_P, too.
2516 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2518 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2520 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2522 Sync from Automake, as follows:
2524 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2525 * config/install-sh: Initialize IFS, so field splitting isn't
2527 * config/mkinstalldirs: Likewise.
2528 * config/missing: Remove superfluous quotes. Replace all uses of
2529 `[' by `test', for consistency, and for..
2530 * config/missing (sed_minuso, sed_output): New variables.
2531 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2532 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2533 Fixes `missing' to detect `--output' for help2man. Fixes
2534 PR automake/483. Report by Dennis J. Linse.
2535 (autom4te): Document in `missing --help'.
2537 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2539 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2540 * config/install-sh: Don't use 'path' to talk about file names,
2541 as per GNU coding standards. Close a race condition reported by Ralf
2542 Wildenhues and Stepan Kasal. There is still a race condition
2543 on hosts that predate Posix 1003.1-1992, but we can't help this.
2544 Don't mishandle weird characters like space on pre-Posix hosts.
2545 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2546 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2547 AC_PROG_MKDIR_P from AS_MKDIR_P.
2548 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2549 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2550 earlier editions are not (including Automake 1.8.3).
2551 Do not suggest mkinstalldirs for thread-safety.
2552 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2553 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2554 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2555 presence of special characters and race conditions.
2556 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2557 in Autoconf's name space.
2559 2006-05-10 Bruno Haible <bruno@clisp.org>
2560 and Paul Eggert <eggert@cs.ucla.edu>
2562 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2563 from Automake with minor changes.
2564 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2566 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2568 * config/install-sh: Update to Automake CVS version, as follows:
2569 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2570 * lib/install-sh: Simplify the expr implementation of dirname.
2571 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2572 * lib/install-sh: Handle --, and diagnose unknown options.
2574 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2576 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2577 `./autom4te' to create `./testsuite', since the `all' target
2578 will ensure its presence, but `installcheck' should not create
2579 the uninstalled wrappers.
2581 * tests/torture.at (Unusual Automake input files): Skip if we
2582 detect automake < 1.8.
2584 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2586 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2587 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2588 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2591 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2593 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2594 munge (multiple) white space and other oddities.
2595 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2596 single quotes in variable assignment.
2597 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2598 and similar failures by adding multiple spaces, tabs, and other
2600 Report and different test suggested by Francesco Romani
2601 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2603 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2604 single quotes, we only need to search for single quotes; this
2605 both simplifies the search pattern, and makes us less
2606 susceptible to `echo' variations for arguments not containing
2608 (_AC_ARG_VAR_VALIDATE): Likewise.
2610 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2612 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2613 `$*' and IFS concatenation issue with traditional shells and
2614 bash-2.04. Report by Seanster@Seanster.com.
2616 2006-05-03 Bruno Haible <bruno@clisp.org>
2618 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2619 precisely which Mac OS X versions have the od problem.
2621 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2623 * doc/autoconf.texi: Use @option systematically.
2625 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2626 and Bruno Haible <bruno@clisp.org>
2628 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2630 (Integer Overflow): Mention the special case of integer division
2633 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2635 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2636 traditional shells like the Solaris one that do not use the
2637 first IFS character for assembling `$*'.
2638 Prompted by a related report from autoconf_bug@nro.ca.
2640 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2641 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2643 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2644 Mention more problems with the -e option.
2646 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2649 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2651 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2652 in URLs to improve DVI formatted output (requires texinfo 4.6).
2653 (System Services, Systemology, Shellology): Likewise.
2654 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2657 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2659 (Runtime): Fix macro argument names to match description:
2660 `action-if-found' -> `action-if-true' and similarly.
2661 (Obsolete Macros): Likewise.
2662 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2663 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2664 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2666 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2668 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2671 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

2676 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2677 /bin/sh set unsorted output.
2678 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

2696 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2698 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2699 since as_me isn't set yet.
2701 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2703 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2704 a few minor bugs in this area.
2706 * doc/autoconf.texi (Programming in M4sh): Comment out the
2707 documentation of AS_BASENAME, for now.
2708 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2709 (Limitations of Builtins) <basename>: Do not refer to
2711 * bin/autoconf.as (me): Don't use AS_BASENAME.
2712 (dir): Remove the unused variable.
2713 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2714 AS_DETECT_REQUIRED. All uses changed.

2724 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2725 (AS_DIRNAME): Use "dirname --".
2727 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2729 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2730 of "run time" and "run-time" changed to "runtime", for consistency.

2733 * lib/autoconf/general.m4: Likewise.
2734 * lib/autoconf/headers.m4: Likewise.
2736 * doc/autoconf.texi (Run Time): Document the exit status situation
2737 with more accuracy and detail.
2739 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2741 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2742 Archive is not officially `GNU' any more. Update URL.
2743 (Defining Directories): Likewise
2744 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2746 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2748 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2749 newline from the `trap' code to finish `config.log'; the NetBSD
2750 /bin/sh resets the exit status after an empty command, as
2751 documented in doc/autoconf.texi.
2752 Reported by Dalibor Topic <robilad@kaffe.org>.
2754 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2756 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2757 Suggested by Bruno Haible.
2759 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2761 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2762 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2763 Instead, just list the shells that we know work.
2764 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2765 changed. Be more cautious about the _cv_ variable.
2766 * tests/tools.at (Syntax of the shell scripts): Check the
2767 _cv_ variable once, at first, to avoid an internal autoconf error
2768 when sh -n does not work.
2770 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2772 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2774 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2776 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2777 use ">&-" since we're only 99.999% sure that this is portable,
2778 and since the MinGW bug is fixed in a different way.
2779 * lib/autotest/general.m4 (AT_INIT): Likewise.
2781 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2783 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2784 before opening config.log, to avoid hitting a bug on MinGW.
2786 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2788 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2789 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2790 This works around a MinGW bug reported by Eric Paire.
2791 Make sure that all writes to the log file append to it,
2792 rather than possibly losing data.
2793 * lib/autotest/general.m4 (AT_INIT): Likewise.
2795 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2797 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2800 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2804 * configure.ac (AC_INIT): Bump to 2.59d.
2806 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2810 * Makefile.maint (news-date-check): Do not require a leading `*'
2811 before the release date in NEWS.
2813 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2814 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2816 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2817 the instantiated file do not contain the string 'datarootdir'
2818 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2819 @mandir@, replace the reference '${datarootdir}' by the value.
2820 * tests/torture.at (datarootdir workaround): New test.
2821 * NEWS: Advertise this temporary fixup.
2822 Based on a patch by Bruno Haible, reported and analyzed by
2823 Paul Eggert and Noah Misch.
2825 2006-04-12 Eric Blake <ebb9@byu.net>
2827 * tests/autotest.at (Debugging a failed test): Fix comment.
2829 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2831 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2832 all the changes since 2006-04-07.
2834 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2836 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2837 succeeded, but `ln -s file dir' failed, take care to remove the
2838 leftover target before the next test, to prevent its spurious
2839 failure; also make sure `ln file dir' works before selecting it.
2840 Thanks to Keith Marshall for pointing this out.
2843 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2844 assignments in `at_debug_args', so that we put them correctly
2845 in the `run' script.
2846 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2847 Reported by Eric Blake.
2849 2006-04-11 Eric Blake <ebb9@byu.net>
2851 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2852 top-level tests after micro-suite has been run. Used in...
2853 (Debugging a successful test, Debugging script and environment),
2854 (Debugging a failed test): ...these new tests. The first of these
2856 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2857 macro, split out from...
2858 (AT_INIT): ...here, so that using -d also generates a run script.
2859 Document that -d inhibits top-level logging.
2860 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2861 inhibits top-level logging; debug scripts are created.
2863 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2865 * tests/autotest.at (Empty test, Empty check): New test to check it.
2867 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2870 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2872 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2873 the files if a problem appears. Make the empty *.at files
2874 read-only, too. Proposed by Ralf Wildenhues.
2876 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2878 * config/Makefile.am: Add comment to force updated Makefile.in.
2880 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2881 space only patch to this file, this patch causes the Makefile.in
2882 files that include freeze.mk to be updated, and thus have a
2883 newer time stamp again, which in turn makes a pristine CVS
2884 checkout have correct time stamps.
2886 * Makefile.maint (cvs-sv): New macro, to be used..
2887 (config.guess-url_prefix, config.sub-url_prefix)
2888 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2889 point to CVS text checkout of Gnulib files.
2890 (copyright-check): Bump current year.
2891 (announcement): Do not hard-wire `./announce-gen'.
2892 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2894 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2896 (wget_files): Update config.guess, config.sub, texinfo.tex by
2897 `wget-update', now that their URLs work again.
2899 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2901 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2902 Problem noted by Paul D. Smith.
2904 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2906 * doc/autoconf.texi: Remove unused words from word list.
2907 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2908 .x-sc_trailing_space: New files.
2910 * doc/standards.texi: Sync from gnulib.
2912 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2913 `LIBOBJDIR' as experimental.
2915 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2916 with a target directory; it's internally implemented as `cp'
2917 anyway, but since Autoconf advertises the possibility to use
2918 a target directory when LN_S is `ln -s', we need to find out.
2919 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2920 analyzed by Keith Marshall <keith.marshall@total.com>.
2924 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2926 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2927 confdefs.h as-is. In general, if it has backslash-newline or the
2928 like, then it doesn't work either to sort or to remove empty
2931 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2933 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2935 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2937 * lib/autom4te.in (Automake-preselections): Preselect
2940 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2942 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2943 apostrophe within a single-quoted string, as this is the usual
2944 tradition and is easier to read than '"'"'. Don't rely on the
2945 shell treating "$/" like '$/'. Use a more-consistent indenting
2948 2006-04-09 Eric Blake <ebb9@byu.net>
2950 * tests/autotest.at (Backquote command substitution),
2951 (Multiline backquote command substitution): Remove mistaken
2952 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2954 (Parenthetical command substitution, Multiline parenthetical
2955 command substitution): here.
2957 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

3032 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3034 Revert the patch from 2006-04-01 and only improve
3035 _AS_DETECT_BETTER_SHELL:
3037 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3038 skip nonexistent directories.
3039 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3040 only shell candidates which exist.
3041 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3042 * lib/autotest/general.m4 (AT_INIT): No need to give three
3043 parameters to _AS_PATH_WALK.
3045 2006-04-07 Stepan Kasal <kasal@ucw.cz>,

3052 test case by Noah Misch <noah@cs.caltech.edu>.
3054 2006-04-07 Stepan Kasal <kasal@ucw.cz>

3063 2006-04-07 Eric Blake <ebb9@byu.net>
3065 * doc/autoconf.texi (Programming in M4sh): Document that
3066 AS_MKDIR_P exits the script on failure.
3067 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3069 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3071 * config/elisp-comp, config/install-sh, config/mdate-sh,
3072 config/missing, config/mkinstalldirs: Sync from Automake.

3087 Paul Eggert <eggert@cs.ucla.edu>,
3088 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3090 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3091 whether `set' quotes correctly: redirect stderr of the tested
3092 `set', and use a subshell, for Ultrix; use `sed' instead of
3093 `grep' for zsh `set' which may write binary output; match only
3094 at the beginning of a line, to avoid false positives.
3095 In order to avoid false positives by unrelated variables with
3096 multiline content, put the dump algorithm in a subshell and
3097 unset all variables containing newlines (except some which are
3098 special to the shell). Warn about cache variables that are
3101 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3103 * config/config.guess, config/config.sub, config/texinfo.tex:
3106 * tests/mktests.sh: Reword comments.

3144 ac_config_<foo>s again, sometimes normalized, sometimes not.
3145 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3146 (AC_CONFIG_COMMANDS): Do not do so here.
3147 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3148 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3149 2005-07-25 rewrite. Noticed by Noah Misch.
3151 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3152 _AC_PRESERVE_HELP_ORDER, ...
3153 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3155 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3156 inside m4_expand_once; it is redundant.
3158 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3159 for --help from Cygnus `configure.'
3161 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3174 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3175 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3176 * doc/autoconf.texi (Help Formatting): New node.
3177 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3179 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3181 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3182 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3183 lib/autoconf/types.m4, lib/autotest/general.m4,
3184 tests/mktests.sh, tests/torture.at: White space cleanup:
3185 remove some SPACE before TAB, or add quoting ('' or @&t@).
3187 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3189 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3191 2006-04-05 Eric Blake <ebb9@byu.net>
3193 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3194 empty test suite works.

3203 normalizing it, consistent it with previous releases.
3204 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3206 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3208 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3209 Use simplified args that Eric Blake originally suggested.
3211 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3213 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3214 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3215 Use 'comm' rather than N instances of grep; this also fixes a bug
3216 whereby substrings were incorrectly matched, causing us to not
3217 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3218 (exclude_list): Exclude empty macros.
3219 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3221 Use awk rather than grep -E or egrep, to avoid
3222 portability problems with regular expressions containing newlines.

3231 a subdirectory subject to Cygnus `configure'.
3232 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3234 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3235 report request when we have no AC_PACKAGE_BUGREPORT.
3237 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3241 * tests/mktests.sh: Update copyright year in the header of the
3244 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3245 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3246 typedef'ed restricted pointer, to catch a compiler bug on
3247 HP-UX 11.x, and fix warnings so it passes with -Werror.

3263 2006-04-03 Eric Blake <ebb9@byu.net>
3265 * THANKS: Add myself.
3267 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3269 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer

4091 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4092 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4093 by the function rather than ignoring it.
4094 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4095 comparing its address. Intel's interprocedural optimization was

4147 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4149 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4150 calls, so that the final expansion of this macro is shorter.
4151 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4152 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4153 the cleanup there. Use AS_VAR_* macros, to be more general.
4154 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.

4181 "if $undefined_var;" succeeds with my shell.
4183 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4184 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

4204 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4205 Update limitations about when to call AC_CONFIG_HEADERS.
4206 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4207 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4208 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4209 ``Configuration Actions''; fix their index entries.
4211 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4212 options correctly. Process N-M as M-N if M is smaller than N.
4213 Process ranges correctly so that N-N will run only N.
4214 Sort and uniquify the tests that will be run. If there is more

4220 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4221 before passing the macro name to AH_TEMPLATE.

4242 Prepend to LIBS, not append, in examples.
4244 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4246 When building in place, set srcdir="."; suggested by Tim Van Holder.
4248 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4249 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4250 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4251 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4252 does not mean "no --srcdir option".
4254 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4256 * tests/autoscan.at (autoscan): New file.

4265 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,

4286 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4288 Rewrite substantial part of lib/autoconf/status.m4.
4289 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4290 and CONFIG_COMMANDS are not processed in four separate loops.
4291 Instead, there is one main loop. This alows that the common code
4292 is expanded only once, thus config.status (and configure) is smaller.
4294 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4295 the AC_LIST_FILES and cousins macros are no longer used.
4297 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4298 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4299 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4300 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4301 contain the initialization, nor the for loop, nor the associated
4302 commands; all these go to ...
4303 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4304 _AC_OUTPUT_CONFIG_STATUS.
4305 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4306 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4307 (_AC_OUTPUT_FILE): The creation of the sed script ...
4308 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4309 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4310 _AC_OUTPUT_MAIN_LOOP.
4311 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4312 _AC_CONFIG_COMMANDS): Use ...
4313 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4314 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4315 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4316 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4317 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4318 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4320 (_AC_CONFIG_UNIQUE): Update.
4321 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4322 Replaced by this ...
4323 (_AC_LIST_TAGS): ... new common macro.
4324 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4325 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4326 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4327 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4328 this didn't belong to the `config commands' section.
4329 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4330 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4331 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4332 to the `config commands' section either.
4333 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4334 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4336 ... and many changes to the comments nearby.
4338 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4339 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4340 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4341 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4342 (#define header templates): The comment at the top of the generated
4343 header now includes the name(s) of the source file(s).
4345 Several unrelated small changes:
4347 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4348 parameter to AC_DIAGNOSE.
4349 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4350 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4351 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4352 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4354 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4355 in AC_OUTPUT doesn't double-quote it either.
4356 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4359 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4361 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4362 versions of Portland Group compiler produce single- and double-quoted
4363 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4364 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4366 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4368 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4369 This is a corrected version of yesterday's patch.
4371 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4373 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4374 path, too; insert a "===" to emphasize the line.
4376 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4377 ac_cv_build_alias to ac_build_alias.
4378 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4380 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4381 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4382 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4383 (AC_ARG_VAR): ... here.
4384 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4387 Keep a list of all precious variables and process them with one simple
4388 for loop, instead of expanding all commands, or, OTOH, complicated
4389 processing of output of "set".
4390 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4391 variable names in new macro...
4392 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4393 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4394 a loop to assign all ac_env_* and ac_cv_env_* variables.
4395 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4397 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4398 its value to shell variable ac_precious_vars and call
4399 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4400 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4401 _AC_ARG_VAR_VALIDATE.
4403 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

4421 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4422 They are generated by the Tru64 v5.1B shell.
4424 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4426 Fix my changes from 2005-07-01; reported by Noah Misch.

4431 Fix cases when the varsions of Autoconf and Autotest don't match.
4432 Reported by Noah Misch.
4433 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4434 at_top_builddir, for compatibility with older autotest.
4435 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4436 is not set, use at_top_builddir, for compatibility with older
4437 versions of autoconf.
4439 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4441 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4442 Problem reported by Patrick Welche.
4444 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4446 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4447 sed substitution command, so that we allow | in program prefixes
4448 and program suffixes. (& is a problem anyway; we're not fixing
4450 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4451 configure_input, top_builddir, srcdir, etc.
4452 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4453 PATH_SEPARATOR in AUTOTEST_PATH.
4455 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

4463 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4464 directories with weird names. Apparently some people like living
4465 on the edge. However, improve the test that "pwd" actually does
4466 report a name for the working directory.

4469 2005-07-01 Stepan Kasal <kasal@ucw.cz>

4486 document to output the default config_* lists to config.status.
4487 Don't recognize option --file, if the functionality is not there.
4488 Likewise for --header; moreover, recognize --he and --h as shortcuts
4489 for --help in that case.
4491 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4492 matches the order of execution. No code changed.

4514 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4515 (AC_SUBST): Call it.
4516 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4517 the directory specific variables; but don't call it for configure_input.
4519 2005-06-28 Derek Price <derek@ximbiot.com>
4521 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4524 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4526 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

4528 due to limitations in Make syntax. Problem reported by Alexandre
4530 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4543 from Justace Clutter.
4544 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4545 variable into diagnostic. Make the diagnostic an error, not a warning,
4546 because we really don't support spaces and suchlike in dir names.
4547 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4548 Don't worry about backslashes in srcdir; it can't happen now.

4592 * doc/autoconf.texi:
4593 Don't mention Solaris versions so much, if a
4594 problem is common to all extant versions of Solaris. Say "SunOS
4595 4" instead of "SunOS" for SunOS 4.
4596 (awk): Mention more of the limitations of traditional Awk.
4597 (cat): Don't talk about cat -v.
4599 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4624 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4625 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4626 to update the man page. That way, we don't have to check in new

4639 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4640 -u, since it outputs chatter if the input files are the same.
4641 Problem reported by Ralf Menzel.
4643 2005-06-08 Derek Price <derek@ximbiot.com>
4645 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4646 renaming them since they are about to be redefined anyhow.
4648 2005-06-08 Derek Price <derek@ximbiot.com>
4650 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4651 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4652 Move m4_undefine to alphabetical order.
4654 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

4657 * doc/autoconf.texi (Introduction): Likewise.
4658 Reword to avoid some formatting glitches.

4660 Clarify explanation of HP compiler bug.
4661 Redo example output tp match current CVS snapshot.
4662 Use @example.org in email addresses when the examples
4663 might get inadvertently cut-and-pasted into user code.
4664 Remove example of autom4te usage that doesn't seem to work now.
4665 Use modern AC_INIT (except when the example is meant to be
4666 shown with Autoconf 2.13).
4667 Update ksh info for Solaris 9 and later.
4669 Modernize description of Automake versions a bit.
4670 Don't claim a future version of Autoconf is near.

4680 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4681 Tru64 ksh pattern matching bug. Reported against Libtool by
4682 Albert Chin <libtool@mlists.thewrittenword.com> and
4683 Nicolas Joly <njoly@pasteur.fr>.
4685 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4687 m4_cdr of one-member list was [[]] (one-member list containing an
4688 empty string) instead of [] (an empty list. Callers were skewed to
4689 match this misbehaviour. As a consequence of this:
4690 - m4_foreach([x], [], [foo]) expanded to `foo', while
4691 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4692 This bug has been fixed:
4694 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4695 expand to an empty string; print error msg if called without
4697 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4698 misbehaviour; handle [] and [[]] correctly.
4700 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4702 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4703 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4704 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4706 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4708 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4709 swallow records with more than 99 fields.
4710 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4711 parse the long line.
4713 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4715 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4716 swallow literals longer than 399. Reported by Ralf Wildenhues.
4717 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4718 to workaround this limitation.
4720 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4722 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4723 to gfortran, and make these the first two compiler names
4724 checked (following the general autoconf preference for gcc).
4726 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4728 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4729 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4730 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4732 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4734 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4735 expression of unbounded size when processing the --list
4736 option. This runs afoul of a limit of 399 bytes per regular
4737 expression on AIX. Problem reported by Ralf Wildenhues.
4739 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4741 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4742 * doc/autoconf.texi (Particular Headers): Reword example
4743 for multiline stdbool replacement.
4744 (Setting Output Variables): Reword text a bit. Don't
4745 give all the details about |#_!!_#|.
4746 Reword description of line replacement.
4748 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4750 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4751 now contain newlines, and substituted files must be referenced on
4752 a line alone; the sed scripts to substitute them are now very
4754 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4755 commands can be put in a sed script portably.
4756 * doc/autoconf.texi (Setting Output Variables): Document above
4757 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4758 use of multiline substitution.
4759 * tests/torture.at: No longer expect substitution of newline to fail.
4761 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4763 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4764 From Ralf Menzel (trivial change).
4766 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4768 * tests/local.at: Don't attempt to check for negated character
4769 classes in shell scripts. The test was too brittle.
4771 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4773 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4774 * doc/autoconf.texi (Limitations of Builtins): Document this
4777 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4779 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4780 common code; used in many places in the tree.
4781 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4782 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4784 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4786 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4787 messages when ac_unique_file is not found.
4788 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4789 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4790 commands, for consistency with AC_MSG_ERROR and such.
4792 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4794 * bin/Makefile.am: Merge the two rules for creating scripts.
4796 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4798 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4799 obsolete; it was never documented.
4800 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4802 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4804 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4805 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4806 (ac_top_builddir): ... this ...
4807 (ac_top_build_prefix): ... to this; the old name is also kept, for
4808 backward compatibility.
4809 (ac_top_builddir_sub): New variable, without the trailing slash,
4811 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4812 * doc/autoconf.texi (Configuration Actions): Rename
4813 ac_top_builddir to ac_top_build_prefix.
4814 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4815 at_top_builddir to at_top_build_prefix.
4816 * lib/autotest/general.m4 (AT_INIT): Likewise.
4818 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4820 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4823 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4825 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4826 argument to m4_foreach. I guess it was necessary in the past,
4827 but I think it's a no-op now.
4829 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4831 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4832 ``cat <<_ACEOF'' commands to one.
4833 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4834 * lib/autoconf/status.m4: On various places, use expr instead of
4836 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4837 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4838 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4840 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4841 the wrong patterns between ``case'' and ``esac.'' The previous
4842 code had false positives.
4844 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4846 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

4889 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4891 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4893 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4894 enough arguments, similarly as in m4_bpatsubsts.
4896 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4898 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4901 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4903 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4904 for absolute directory names in one loop.
4905 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4906 abbreviations of --version and --debug.
4908 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4910 * doc/autoconf.texi (Autoconf Language): Be more precise about
4911 quoting rules. Problems noted by Stepan Kasal.
4912 Also, throughout this document, be more careful about white space.
4913 "blank", "white space", and "space" all have different meanings
4914 and we should be careful to say what we mean.
4916 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4918 Fix C++ related problems reported by Werner Lemberg.
4919 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4920 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4921 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4922 avoid problems with C++ and throw.
4923 * tests/compile.at: .cpp, not .cc.
4925 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4927 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4929 * doc/autoconf.texi (Generic Functions): Typos.
4931 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4933 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4934 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4935 set by latest automake.
4937 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4939 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4940 outputs 0 on GNU/Linux these days.
4942 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4944 * doc/autoconf.texi (Autoconf Language): Add more description
4945 about quoting heuristics.
4946 (Limitations of Builtins): Describe "set -" problems.
4948 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4950 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4953 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4954 by AC_DEFINE; it was a mistake.
4955 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4957 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4959 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4961 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4963 * doc/autoconf.texi (External Software): Quadrigraphs are not
4964 processed correctly in AS_HELP_STRING; avoid this in the examples.
4965 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4966 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4967 comment and reduce m4_default([foo], []) to [foo].
4968 (m4_strip): Update the explanation.
4970 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4972 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4973 Remove core.conftest.* too; it's generated by Tru64 5.1.
4974 Problem reported by Jennis Pruett.
4975 * lib/autoconf/functions.m4
4976 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4977 Don't bother to remove core files; AC_RUN_IFELSE should do that
4980 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4982 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4984 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4986 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4987 Report from Horst Wente.
4989 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4991 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4994 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4996 * doc/autoconf.texi (External Software, Package Options): Add
4997 examples showing how to implement --with-* and --enable-* options.
4999 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5001 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5002 as well as configure.in. Problem reported by Gregorio Guidi.
5004 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5006 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5007 pattern for alloca snippet.

5019 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5020 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5022 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5024 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5025 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5026 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5027 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5028 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5030 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5032 * NEWS: The configure command now warns you if you attempt to use
5033 a directory whose name contains a special character like space,
5035 * doc/autoconf.texi (Installation Directory Variables): Allow
5036 "," in file names. Do not use \@; it's not a portable regexp.
5037 * bin/Makefile.am (edit): Likewise.
5038 * lib/Makefile.am (edit): Likewise.
5039 * tests/Makefile.am (edit): Likewise.
5040 * tests/semantics.at: Likewise.
5041 * tests/torture.at: Likewise.
5042 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5043 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5044 * doc/autoconf.texi (File System Conventions): Warn about
5045 unportable file names.
5046 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5048 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5049 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5050 ac_pwd, and quote srcdir.
5051 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5053 * doc/autoconf.texi: Fix some systematic formatting problems.
5054 ".)" needs a following @: if not at the end of a sentence, and
5055 similarly for "!)". "etc." should be preceded by a comma.
5056 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5058 2005-03-22 Bruno Haible <bruno@clisp.org>
5060 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5061 argument is often called 'build-aux'.
5063 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5065 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5066 macro AC_TRY_LINK is obsolete.
5067 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5070 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5072 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5073 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5074 from a Common Lisp's `cl'.
5075 (AC_PROG_CXX): Behave according to the documentation: don't
5076 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5077 make the variable CCC precious; use `cl.exe', not `cl'.
5079 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5080 Alexandre Duret-Lutz <adl@gnu.org>
5082 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5083 /dev/null, as "configure" shouldn't read stdin, and this insulates
5084 us from problems (e.g., when testing for "cl"). Also, do this
5085 redirection before invoking "hostname" or "uname", and keep the
5086 original input stream available via...
5087 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5088 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5089 bother with "</dev/null" since it's now done at the top of
5091 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5092 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5093 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5094 * doc/autoconf.texi (File Descriptor Macros): New section.
5095 (Printing Messages): Mention it.
5096 * tests/base.at (Input/Output): New test.
5098 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5100 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5101 newline if neither \c nor -n work, as that would output two
5102 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5104 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5106 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5107 This causes that any required macros inside will get before the if.
5108 * doc/autoconf.texi (autom4te.cache): A typo.
5110 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5112 Undo previous change, except keep the change to
5113 lib/autoconf/programs.m4 that replaced grep with shell
5114 pattern-matching. This is because net-snmp configure reads stdin.
5115 Reported by Noah Misch.
5117 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5119 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5120 from /dev/null, as "configure" shouldn't read stdin, and this
5121 insulates us from problems (e.g., when testing for "cl").
5122 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5123 before invoking "hostname" or "uname".
5124 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5125 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5126 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5127 "</dev/null" since it's now done at the top of 'configure'.

5235 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

5238 2047-byte limit on line length of portable text files.
5239 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5240 Use newline as a separator, not space.

5298 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5299 Update the long comment explaining it.
5301 m4_require no longer writes an ``is required by'' line to the
5302 execution stack. It contains only one bit of non-redundant
5303 information: that the macro was required, not called. And even
5304 this bit is useless in most situations: have you ever met a macro
5305 which both calls and requires the same macro?
5307 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5308 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5355 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5356 Warn about newline stripping in `` and $(). Update Solaris
5358 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5359 X insulates us from future changes to Posix.
5360 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

5387 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5413 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5414 stored in _m4_divert_diversion or _m4_divert_dump.
5415 (m4_divert_pop): When the parameter is given, compare the symbolic
5416 name with the last diversion pushed on the stack. Previously, the
5417 current diversion was compared with the numeric value of the
5418 diversion given as the parameter.
5419 (m4_require): If the macro hasn't been expanded yet, call ...
5420 (_m4_require_call): this new macro.

5699 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5701 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5702 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5703 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

5725 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5727 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5728 "char c = '\200';" rather than "char c = 0x80;" as the

5730 overflow on signed char hosts.
5732 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5733 to -qlanglvl=ansi. We don't want to disable extensions.

5789 simplify the examples and improve their quoting.
5791 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5793 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5794 the $1_found variable, don't test whether the file is executable;

5846 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5847 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5848 (trivial change). Problem and patch reported by Andrew Church in:
5849 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

5878 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5879 texinfo.tex for now (done by hand now).
5880 * Makefile.maint (wget_files, cvs_files):
5881 Remove ansi2knr.c; nobody uses it.
5882 (ansi2knr.c-url_prefix): Remove.
5883 (cvs-update): Fix test for failure. I don't know why it ever
5886 * doc/autoconf.texi: Update URLs, some of which went stale.
5887 Use @uref rather than @href.
5889 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5890 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5892 * config/config.guess, config/config.sub, config/elisp-comp,
5893 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5894 doc/fdl.texi, doc/standards.texi: Sync with master copy.

5902 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5903 tests/tools.at, tests/torture.at:
5904 Use "file name" rather than "filename" or "path",
5905 to be consistent with the terminology of the GNU coding standards.
5907 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5909 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

5914 More fixes to support spaces in the name of the build directory.
5915 This isn't a complete fix but it's an improvement.
5917 * bin/autoconf.as (autom4te_options): New var.
5918 Use it instead of appending to AUTOM4TE, so that we can allow
5919 spaces in the build directory's absolute name.
5920 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5921 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

5935 and isnan. From a suggestion by Kevin Ryde.
5937 * lib/Autom4te/General.pm (END): Return correct exit status even
5938 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5940 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5942 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5943 for compatibility with Automake 1.4. Reported by J C Fitzgerald in

5952 * lib/autom4te.in (Automake-preselections): Preselect
5953 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5955 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5957 * lib/autom4te.in (Automake-preselections): Preselect
5958 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5961 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5963 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

5970 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5971 with pdksh, too. Problem reported by Patrick Welche via
5973 * doc/autoconf.texi (Shellology): Note that set -o posix is
5974 useful for pkdsh, too.
5976 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5978 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5979 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5980 Don't fail if ENV or BASH_ENV is readonly.
5981 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5982 etc. are read only. Problem reported by Ludovic Courtes.
5984 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5986 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

5990 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5992 * doc/autoconf.texi (File System Conventions): Warn about
5993 names like "aux". Problem reported by Eric Blake.
5995 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5996 by zero instead of array size, so that we can use any arithmetic
5997 constant expression (instead of requiring an integer constant
5998 expression). This allows us to test expressions like DBL_MAX <
5999 LDBL_MAX, which didn't conform to the C standard using the old
6001 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6002 now that we can do floating-point tests at compile time.
6004 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6006 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6007 and LDBL_EPSILON, as the resulting expression isn't an
6008 integer constant expression and violates the C standard.
6009 Problem reported by Nelson H. F. Beebe. Also, check
6010 for "L" suffix, and check that long double doesn't have
6011 worse range or precision than double, that mixed-mode
6012 arithmetic doesn't generate a diagnostic, that double
6013 constants fit in long double.
6015 2004-06-03 Kevin Ryde <user42@zip.com.au>
6017 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6018 malloc(0) and realloc(NULL,size).

6023 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6025 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6026 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6029 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6031 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6032 can be rewritten using if-then-else. Suggested by Bruno Haible.

6039 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6041 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6042 change). Patch reported by Ralf Wildenhues in
6043 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6045 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6046 function F exists if the compiler and linker let you compile an
6047 expression like (F != 0). Recent versions of GCC optimize away
6048 the reference to F in that case, since every function address must
6049 be nonzero, so the link succeeds even if F does not exist.
6050 Problem reported by Manu in
6051 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6053 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6054 "Unix". Many uses changed.
6055 (Limitations of Builtins): Explain better why the ! command isn't

6060 * lib/autom4te.in (Automake-preselections): Preselect
6061 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

6066 referencing AC_FUNC_STRERROR_R.
6068 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6069 note pessimistic assumption when cross compiling.
6071 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6073 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6074 (until 2004) invoked subcommands with sh -e, contra POSIX.
6075 Reported by Kevin Ryde.
6077 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6079 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6080 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6081 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6082 `test -f " /usr/bin/grep"', which _always_ failed.
6083 (AC_PROG_SED): Ditto bogus PATH fix.
6084 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6085 requires that grep correctly supports _multiple_ `-e' options, rather
6086 than stating only that grep should accept `-e'.
6088 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6090 Port to C99, which requires that 'exit' be declared.
6092 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6093 to ensure that stdlib.h is included.
6094 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6095 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6096 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6097 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6098 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6099 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6100 when using 'exit' in a test; C99 requires that 'exit' be declared.
6102 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6104 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6105 now prefers 'grep' implementations that accept -e.
6106 (Limitations of Usual Tools): Describe problems of traditional
6107 egrep and fgrep with long input lines, and of traditional grep
6109 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6110 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6111 All callers changed. Append /usr/xpg4/bin to the PATH, for
6113 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6114 the user with complaints about multiple -e options.
6115 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6116 Define it with AC_PROG_GREP.
6117 * configure.ac (AC_PROG_GREP): Add.
6118 * lib/freeze.mk (GREP): New macro.
6120 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6122 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6123 a possible candidate only after all others fail, rather than
6124 consulting it first. This improves backward compatibility by
6125 better reflecting the way shell selection occurred in previous
6126 versions of Autoconf, and should help to avoid triggering latent
6127 problems in other packages, such as the one in Automake where zsh
6128 is not handled robustly:
6129 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6130 Although it is not Autoconf's responsibility to work around
6131 problems in Automake, it nevertheless makes sense to avoid
6132 introducing unnecessary incompatibilites.
6134 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6135 Gary V. Vaughan <gary@gnu.org>
6137 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6138 how deeply nested we are when a suitable tool is found, set the
6139 ac_path_TOOL_found flag.
6140 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6141 nested we are in this macro. Break out of all 3 nested loops if
6142 ac_path_TOOL_found is set.
6144 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6146 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6147 of the _AS_PATH_WALK loop too if GNU flavor is found.
6149 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6151 * doc/autoconf.texi (Limitations of Make): Update documentation
6152 for `$<'. New entry `Long lines', based on a report from Simon
6153 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6154 paragraph about DJGPP, based on a mail from Richard Dawe.
6156 2004-04-20 Paul Eggert <eggert@twinsun.com>
6158 * tests/c.at (C keywords): Don't assume that GCC supports
6159 "restrict" and "inline", as sufficiently-old GCC versions do not
6160 (also, GCC configured to be in pedantic C89 mode does not).
6161 Problem reported by Sumit Pandya in:
6162 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6164 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6165 consider -g to work if it generates warnings when plain compiles
6166 don't. Problem reported by Braden McDaniel in:
6167 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6169 * doc/autoconf.texi (Slashes): New section, to document a problem
6170 reported by Jim Meyering in:
6171 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6173 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6174 linker output files before linking, to work around IRIX 6 linker bug.
6175 Problem reported by Rainer Orth in:
6176 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6178 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6180 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6181 best tool so far counter rely on the tool path variable name to
6182 avoid checks for one tool being affected by the results of running
6183 the length check on a previous tool.
6185 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6186 match expression argument, as different greps have different
6187 regular expression flavours.
6188 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6190 (AC_PROG_EGREP): Pass 'EGREP$'.
6191 (AC_PROG_GREP): Pass 'GREP$'.
6193 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6195 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6196 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6198 2004-03-29 Paul Eggert <eggert@twinsun.com>
6200 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6201 Types, Specific Compiler Characteristics, System Services,
6202 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6203 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6204 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6205 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

6216 2004-03-28 Paul Eggert <eggert@twinsun.com>
6218 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6219 now defines HAVE_DECL_TZNAME if it is declared, when
6220 HAVE_STRUCT_TM_TM_ZONE is not defined.
6221 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6222 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

6229 thanks to Paul Eggert.
6231 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6233 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6234 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6235 H. F. Beebe for the bug report.
6237 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6239 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6240 quoted -cmdline argument in Portland Group compiler (bug
6241 reported by Jeffrey J. Barteet).

6291 * bin/Makefile.am (edit): Don't use $< in a context where
6292 POSIX doesn't require support for it. Use $@.in instead.
6293 Problem reported by Anthony N. Frasso in
6294 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6295 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

6299 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6300 from the next generation of Libtool.

6303 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6305 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6306 is not always thread-safe. Report from Nathanael Nerode.
6308 2004-02-18 Paul Eggert <eggert@twinsun.com>
6310 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6311 problem on QNX reported by Stephen Rasku in
6312 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6314 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6315 $(m4sh_m4f_dependencies); this removes a FIXME.
6316 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6317 (MAINTAINERCLEANFILES): Split into pieces,
6318 one per related section. Add $(srcdir)/wrapper.in.
6320 2004-02-09 Paul Eggert <eggert@twinsun.com>
6322 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6323 AC_SUBST provides no portable way to escape literal newlines.
6325 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6326 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6327 Darwin uses -lcrt2.o and there's little point to cataloging all
6328 the system variants. Partial fix reported by Andreas Waechter in:
6329 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6345 the behavior of the third argument.
6346 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6347 correctly the behavior of the third argument. Document
6348 what the three macros that AU_DEFUN defines do. Fix
6349 warning message when the third argument includes $0

6404 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6405 2003 (except 1997) to the list of copyright years. This undoes
6406 the 2003-05-22 change, which removed the older years from the list.
6407 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

6418 egrep and fgrep respectively if $GREP -E/-F don't work.
6419 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6420 _AC_PROG_GREP, and AC_PROG_SED.

6451 2004-01-26 Paul Eggert <eggert@twinsun.com>
6453 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6454 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6455 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6456 not <inttypes.h>. Problem reported by Tim Mooney in
6457 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6458 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6461 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6462 otherwise "make check" fails because it forbids cmp (I guess
6463 because cmp treats files as binary on DOS-like systems).
6465 * tests/mktests.sh: Update copyright date to 2004, since some tests
6466 have changed in 2004.
6468 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6470 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6471 non-truncating sed or gsed program in PATH.

6476 2004-01-15 Paul Eggert <eggert@twinsun.com>
6478 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6479 -std1 disables some useful extensions on Tru64. Problem reported
6481 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6483 2004-01-14 Paul Eggert <eggert@twinsun.com>
6485 * doc/autoconf.texi (Programming in M4sh): Document that
6486 AS_MKDIR_P succeeds if the destination is a symbolic link
6487 to an existing directory.
6488 (Limitations of Usual Tools): Note that mkdir -p might not
6489 succeed on symlinks to directories.

6509 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6510 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6511 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6512 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6513 AC_COMPILE_IFELSE, since we now assume our caller invokes
6514 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6515 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6516 of AC_RUN_IFELSE; this avoids the warning mentioned above.

6522 `"'...'"`, as it's confusing (and I suspect it may not work on

7013 Actually, use AU_ALIAS.
7016 2003-09-26 Paul Eggert <eggert@twinsun.com>
7018 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
7019 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
7020 Problem reported by Eric Sunshine in:

7025 The test suite are sometimes assigning timings incorrectly.
7026 Reported by Henk Krus.
7027 Diagnosed by Nicolas Joly.
7029 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7031 Instead of making AT_help a sequence of assignments to grow
7032 $at_help_all, just make AT_help_all be the growing contents of
7033 $at_help_all, and make a single assignment in...
7035 (at_times_skip): Flip the meaning and rename as...
7037 (AT_INIT): When summarizing the test that ran, remove
7038 $at_times_file after use, and check it is present before trying to

7045 * bin/Makefile.am (edit): Handle '@configure_input@'.
7046 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7047 (ifnames): chmod -w.
7048 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7049 executables, not bin/ executables! Otherwise all the magic needed
7050 to find non installed files is turned off. This caused a failure
7051 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7052 as found in its environment (sent by tests/autoreconf): pointing
7053 to bin/autom4te that could not find its files.
7054 * tests/mktests.sh: Force the replacement of generated files, for
7055 the sake of "mv" program that are interactive when overwriting a
7057 * config/install-sh: Upgrade from CVS Automake.

7067 Trivial change to support GCC's configuration procedure.

7132 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7133 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7135 2003-09-04 Akim Demaille <akim@epita.fr>
7137 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

7142 * bin/autom4te.in: Use &fatal where more appropriate than &error.

7146 2003-09-04 Akim Demaille <akim@epita.fr>
7148 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7150 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7152 Add support for newer Fortran dialects. The F77 interface is
7153 unchanged, and continues to support Fortran 77. New FC macros
7154 correspond to all the old F77 macros, with output variables FC,
7155 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7156 available dialect, but older dialects can be specified. There are
7157 new macros AC_FC_SRCEXT to set the source extension, and
7158 AC_FC_FREEFORM to accept free-form source files.
7160 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

7191 2003-08-27 Akim Demaille <akim@epita.fr>
7193 * tests/m4sugar.at (cross_warning): Make sure to enable the
7194 output, so that we can track spurious m4sugar output.
7195 * tests/local.at: Require 2.57.
7196 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7197 are defaulted by AT_CHECK anyway.
7198 Use AT_CHECK_AUTOM4TE.
7199 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

7205 when -Wobsolete is set.
7206 Set it on by default.
7207 Suggested by Klee Dienes.
7209 2003-08-27 Akim Demaille <akim@epita.fr>

7274 Use &verb, not &verbose.
7276 2003-08-21 Akim Demaille <akim@epita.fr>
7278 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7280 ($help): Use Autom4te::ChannelDefs::usage.
7281 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7282 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7284 2003-08-21 Akim Demaille <akim@epita.fr>
7286 First stab at preserving warnings between calls to autom4te,
7287 including when the cache is used.
7289 There are still several issues: (i) there are too many runs of m4
7290 (one for include, one for warnings, and some more), (ii) warnings
7291 spreading on several lines are not handled gracefully, (iii) the
7292 code meant to have the call stack display for errors does not work
7293 (its handling should move from m4 to autom4te).
7295 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7297 (@preselect): Add m4_warn.
7298 ($exit_status): Remove, use $exit_code.
7299 ($help): Use Autom4te::ChannelDefs::usage.
7300 (&handle_m4): No longer define the m4_warnings.
7301 At each run, extract and report the warnings.
7302 Always cache the result, including if the exit status is on
7303 failure, since if nothing changes, we should result in the same
7304 failure, hence we can use the cache.
7305 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7306 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7308 (m4_warn): Redefine as a do-nothing: it is its invocation that
7309 matters, as warnings are now reported via traces.
7310 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7311 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7312 the latter reveals calls to the former.
7316 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7318 2003-08-21 Akim Demaille <akim@epita.fr>
7320 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7323 2003-08-21 Akim Demaille <akim@epita.fr>
7325 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7327 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7328 (&parse_warnings): Accept a list of warning requests.
7329 (&usage): Return a string, not a side effect.
7330 (cross): New warning category.

7339 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7340 * bin/autoscan.in: Adjust.
7342 2003-08-20 Akim Demaille <akim@epita.fr>
7344 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7345 Reported by Alexandre Duret-Lutz.
7347 2003-08-20 Akim Demaille <akim@epita.fr>
7349 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7350 * bin/autom4te: Adjust.
7351 In particular, be Autoconf tools are really silent when properly
7352 working, bind the verbosity of the 'note' channel to $verbose.
7353 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7354 (&xsystem, &contents): Remove, since they are exported by...
7355 * lib/Autom4te/FileUtils.pm: this.
7357 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7358 * lib/Autom4te/FileUtils.pm: here.

7416 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7417 shorter column three. Add DESCRIPTION to log file content.
7419 2003-08-13 Derek Price <derek@ximbiot.com>
7421 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7424 2003-08-12 Derek Price <derek@ximbiot.com>
7426 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

7443 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7444 -lcrt1.o, for OS X. (trivial change)
7446 2003-07-07 Paul Eggert <eggert@twinsun.com>
7448 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7449 inside '#ifndef __cplusplus'. Problem reported by

7454 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7455 'long', not 'int', for benefit of Sun's recent C++ compilers
7456 (trivial change). See:

7477 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7478 not all of them. This fixes 1. the fact that when testing
7479 Autoconf there are many many config.log, 2. the incorrect use of
7480 top_srcdir to find config.log.
7481 Don't mix the detailed output of failed test with the summary of
7482 failures. Rather, append detailed log afterwards.
7484 2003-06-23 Akim Demaille <akim@epita.fr>

7560 is the inverse of localtime.
7562 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7564 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7565 (handle_exec_errors): New function. Work around $! being
7566 altered by WEXITSTATUS.
7567 (xqx, xsystem): Use handle_exec_errors.
7569 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7571 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7572 Do not call `_exit()', simply modify `$?'.
7573 (xsystem): Reset $! before running system, and check it afterward.
7574 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7575 63 for version mismatches.
7577 2003-05-23 Akim Demaille <akim@epita.fr>
7579 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7580 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7581 the middle of a line).
7582 * lib/m4sugar/m4sugar.m4: Likewise.
7583 Remove useless spaces in comments.
7585 2003-05-23 Akim Demaille <akim@epita.fr>
7587 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7588 exit 63, so that we (or Automake's "missing") can tell the
7589 difference with a plain failure.
7590 * doc/autoconf.texi (Notices): Adjust.

7599 Paul Eggert <eggert@twinsun.com>
7601 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7602 Remove `#include <stdlib.h>' from the list; we should never
7603 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7604 resulting namespace pollution would cause other tests to fail.
7605 Configure scripts run with some older versions of g++ and HP's
7606 aCC would fail due to such an #include. Problems reported by
7607 Matthew Mueller in <http://bugs.debian.org/120704> and by
7609 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7610 In the test, use the test declaration before including <stdlib.h>,
7611 as that's closer to how it'll be used.
7613 2003-05-23 Akim Demaille <akim@epita.fr>
7615 * doc/autoconf.texi (Header Portability): ucred.h.
7618 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7620 Overhaul Autotest's logging: generate separate log files
7621 in testsuite.dir/NNN/testsuite.log, and append them to
7622 testsuite.log instead of re-running the test verbosely.
7624 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7625 file descriptor, write 0 to at_status_file instead of setting
7626 at_status=0, initialize some new variables (at_status_file,
7627 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7628 to rerun the tests, instead append the at_group_log to the
7629 at_suite_log when a test fails.
7630 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7631 with the AS_MESSAGE_LOG_FD redirected to stdout.
7632 (AT_CLEANUP): save the output status in $at_status_file
7633 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7635 (AT_CHECK): since tests are run with a redirected stdout,
7636 and used to be re-run in verbose mode, turn some $at_verbose
7637 into echo, and don't redirect the output of testing stdout
7640 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7641 the name of the debugging directory and information about
7644 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

7761 2003-05-06 Akim Demaille <akim@epita.fr>
7763 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7764 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7765 by aclocal.m4 is changed it might require the importing of another
7766 m4 extension file, i.e., aclocal must be run.
7768 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7769 (&parse_args): Use --force with aclocal if required and supported.
7770 (&autoreconf_current_directory): Use &run_aclocal.

7776 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7777 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7778 argument instead of a file name, so that the request file remains
7779 open during the whole autom4te run.
7780 ($icache_file): New.
7781 (&freeze): Lock the $icache_file.
7783 2003-04-29 Derek Price <derek@ximbiot.com>
7785 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7786 seperator with m4_append_uniq(). It doesn't work.
7787 (AT_CLEANUP): Add `;' to end of at_help_all.
7788 (AT_INIT): Allow --keywords to be specified more than once. When
7789 grepping $at_help_all for keywords, use the field and keyword
7790 seperators to ensure a complete keyword match. Alter at_prev handling
7791 to support the new --keywords behavior.
7793 2003-04-27 Karl Berry <karl@freefriends.org>
7795 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7796 align better with others. I also made some of the individual
7797 entries on one line, for brevity and to make it easier for me to
7798 sort my dir-example file in the Texinfo distribution :).

8018 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8019 innocuous variant befor including <limits.h> or <assert.h>. This

8028 * NEWS, configure.ac: Update version.
8030 * doc/fdl.texi: Upgrade to FDL version 1.2.
8032 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8033 nontrivially in main's body, so that f's external declaration is
8034 not optimized away in AIX. This should fix the bug reported by
8036 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8038 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8039 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8040 defined, to support freestanding compilers. This should fix the
8041 bug reported by Momchil Velkov in

8050 * Makefile.maint (www-gnu): New macro.
8051 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8052 the location has moved.
8054 2002-12-02 Martin Frydl <martin@systinet.com>
8056 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8057 \(.*\) match is too long and there is something more to be checked.

8076 Update from masters.
8078 2002-11-14 Akim Demaille <akim@epita.fr>
8080 * Makefile.maint: Sync with Bison, i.e.:
8081 (po-check): Scan .l and .y files instead of the
8082 .c and the .h files that they generate. This fixes the bug
8083 reported by Tim Van Holder in:
8084 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8085 Look for N_ as well as for _. Try to avoid matching #define for

8101 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8102 than assigning in main, to avoid HP cc +O3 optimizing it away.

8106 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8107 option. Process --recheck after parsing all options. Pass -q

8140 Reported by Ezra Peisach.
8142 2002-11-05 Akim Demaille <akim@epita.fr>
8144 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8146 We _have_ to stop using the old compatibility scheme that tried to
8147 avoid useless backslashes because Libtool 1.4.3 contains a
8148 AC_DEFINE([error_t], [int],
8149 [Define to a type to use for \`error_t' if it is not
8150 otherwise available.])
8151 We _have_ to quote the single quote and backslashes with \. The
8152 old compatibility scheme saw that ` was backslashed, and therefore
8153 did not quote the single quote. Hence before this patch, Autoconf
8154 was not compatible with Libtool.
8156 2002-11-04 Paul Eggert <eggert@twinsun.com>
8158 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8241 Use it with an argument, as prototyped.
8244 2002-10-29 Akim Demaille <akim@epita.fr>

8550 (&files_to_options): New function.
8551 (&freeze): Use &error.
8552 (&up_to_date): If a file that was included according to the cache
8553 is no longer there, then the output is out dated.
8554 (&main): Don't even check whether a file is up to date is anyway
8556 * tests/tools.at (autom4te cache): New.
8558 2002-10-16 Akim Demaille <akim@epita.fr>
8560 * bin/autoconf.as: Kill dead options.
8561 * bin/autoupdate.in (&parse_args): Kill old options.
8562 * bin/autoreconf.in (&parse_args): Remove dead options.
8564 (&autoreconf): Report the directories we enter *and leave*, so
8565 that error messages can be easily located, and use GNU Make
8566 format, so that Emacs' compile mode understands us.
8567 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8568 if some file was changed instead of `print'.
8569 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8570 (&parse_args): Remove the dead options.
8571 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
8572 autoheader's quiet mode.
8573 (AT_CHECK_AUTOUPDATE): Likewise.
8574 * tests/tools.at (autoupdate): Adjust.
8575 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8577 2002-10-11 Akim Demaille <akim@epita.fr>
8579 No longer use CPP to check for the existing of headers: use CC to
8580 check for compilability.
8582 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8583 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
8584 (_AC_CHECK_HEADER_NEW): Rename as...
8585 (AC_CHECK_HEADER): this.
8587 * lib/autotest/general.m4 (AT_INIT): Include the failed test
8588 numbers in the Subject suggestion.
8590 2002-10-11 Akim Demaille <akim@epita.fr>
8592 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
8593 Suggest using AC_CHECK_DECLS instead.
8595 2002-10-11 Akim Demaille <akim@epita.fr>
8597 * tests/torture.at (AC_ARG_VAR): Have configure report the value
8600 2002-10-11 Akim Demaille <akim@epita.fr>
8602 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8603 file name to enable parallel executions.
8604 From Sam Varshavchik.
8606 2002-10-08 Akim Demaille <akim@epita.fr>
8608 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8609 aclocal invocation, as Gettext macros might not be visible to
8611 Instead of blindly running autopoint, scan configure.ac (not the
8612 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8613 Reported by Paul D. Smith.
8615 2002-10-08 Paul Eggert <eggert@twinsun.com>
8617 Work around problems found when POSIXLY_CORRECT=1 is set.
8618 None of this seems to have anything to do with POSIX, really,
8619 but it's how Perl getopt works.
8620 * bin/autom4te.in (parse_args): Configure GetOpt with
8622 * doc/autoconf.texi (Invoking autom4te):
8623 --warning -> --warnings.
8624 * lib/autom4te.in: --warning -> --warnings.
8626 2002-09-28 Akim Demaille <akim@epita.fr>
8628 * doc/autoconf.texi (autom4te.cache): New section.
8630 2002-09-28 Akim Demaille <akim@epita.fr>
8632 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8633 (Automake-preselections): Update.
8634 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8636 2002-09-28 Akim Demaille <akim@epita.fr>

8640 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8641 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8643 2002-09-28 Akim Demaille <akim@epita.fr>
8645 * tests/torture.at (Configuring subdirectories): Be robust to
8646 users who use config.site to require for a cache: in this case,
8647 the two last configure runs, using two different sets of
8648 arguments, trigger a legitimate error.
8650 2002-09-28 Akim Demaille <akim@epita.fr>
8652 * tests/m4sh.at (Functions Support, Functions and return Support):
8655 2002-09-28 Akim Demaille <akim@epita.fr>
8657 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and

8680 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8681 that were listed in the original autoscan.list.
8682 * lib/autoconf/headers.m4: Similarly with headers.
8683 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8684 (.m4.m4f): Don't pass --prepend-include, since that's done by
8685 tests/autom4te itself.
8686 * lib/autoscan/Makefile.am: Include freeze.mk.
8687 (autoscan.list): New target --this file is no longer a source.
8688 (autoscan.pre): New file.
8690 2002-09-28 Akim Demaille <akim@epita.fr>
8692 * bin/autoscan.in (@kinds): Make them singular.
8694 (&init_tables): When --debug, report the list of rules to ease
8695 tracking changes in autoscan.list.
8696 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8698 2002-09-28 Akim Demaille <akim@epita.fr>
8700 * lib/autoscan/functions, lib/autoscan/headers,
8701 * lib/autoscan/identifiers, lib/autoscan/makevars,
8702 * lib/autoscan/programs: Merge into...
8703 * lib/autoscan/autoscan.list: this.
8704 * bin/autoscan.in (&init_tables): Adjust.
8706 2002-09-28 Akim Demaille <akim@epita.fr>
8708 * lib/autoscan/functions, lib/autoscan/headers,
8709 * lib/autoscan/identifiers, lib/autoscan/makevars,
8710 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8711 `functions' line is now prefixed with `function:'.
8712 * bin/autoscan.in (&init_tables): Adjust.
8714 2002-09-28 Akim Demaille <akim@epita.fr>
8716 From now on, autoscan files must always map a macro name to a
8717 word: there is no `default' macro for autoscan.
8719 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8721 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8724 2002-09-28 Akim Demaille <akim@epita.fr>
8726 * bin/autoscan.in (%c_keywords): Remove.
8727 (&used): Keep only track of the words we might be interested in.
8728 (&output_kind): It is no longer needed to look for non active
8731 2002-09-27 Akim Demaille <akim@epita.fr>

8734 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8735 * lib/autoscan/functions: Adjust.
8736 * doc/autoconf.texi (Particular Functions): Adjust.
8738 2002-09-27 Akim Demaille <akim@epita.fr>
8740 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8742 Thanks to Bill Moseley and Paul Eggert.
8743 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8744 the tmpdir must be created.
8745 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8746 dir be in the build tree, instead of $TMPDIR.

8750 * bin/autoscan.in: Improve the comments.
8751 (&parse_args): Drop obsolete undocumented options.
8752 (&output_kind): Output warnings.
8753 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8754 (getwd): Trigger a warning.
8756 2002-09-26 Akim Demaille <akim@epita.fr>
8758 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8759 Reported by Ralf Corsepius.
8760 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8762 2002-09-26 Akim Demaille <akim@epita.fr>
8764 Single suffix rules and seperated dependencies are not portable.
8766 * doc/autoconf.texi (Installation Directory Variables): Update.
8767 (Limitations of Make): Some about `Single Suffix Rules and
8768 Separated Dependencies'.
8769 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8770 (ifnames, autoscan, autom4te): Un-factor into several rules.
8772 2002-09-25 Paul Eggert <eggert@twinsun.com>
8774 * BUGS (Interoperability bugs): New section. Mention libtool
8775 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8777 2002-09-24 Paul Eggert <eggert@twinsun.com>
8779 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8780 make handles suffix-rules differently from GNU make.
8782 * bin/Makefile.am (SUFFIXES, .in): Remove.
8783 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8784 Move the body of the old .in rule here.
8786 2002-09-16 Akim Demaille <akim@epita.fr>
8788 i960 compilers create `b.out' files by default.
8789 Reported by Ralf Corsepius.
8791 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8792 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8794 2002-09-13 Paul Eggert <eggert@twinsun.com>
8796 * doc/autoconf.texi (Particular Headers): Remove obsolete
8797 reference to `struct timezone' in the description of
8800 2002-09-13 Akim Demaille <akim@epita.fr>
8804 * config/config.sub, config/config.guess: Update.
8805 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8806 * Makefile.am: Adjust.
8808 2002-09-13 Akim Demaille <akim@epita.fr>
8810 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8811 reading config.log when the compiler is rejected.
8812 Suggested by Guido Draheim.
8814 2002-09-13 Akim Demaille <akim@epita.fr>
8816 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8817 (chdir_init) might hang when stat'ing mounted directories.
8818 Reported by Vance Shipley.
8820 2002-09-12 Akim Demaille <akim@epita.fr>
8822 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8825 2002-09-12 Akim Demaille <akim@epita.fr>
8827 * doc/autoconf.texi (Defining Symbols): Present two different
8828 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8829 difference between 1 argument calls, and 2-3 argument calls.
8831 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8833 * doc/autoconf.texi: Review grammar and punctuation.
8835 2002-09-11 Paul Eggert <eggert@twinsun.com>
8837 * doc/autoconf.texi: Fix minor formatting, spelling, and
8839 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8840 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8843 2002-09-11 Akim Demaille <akim@epita.fr>
8845 * doc/autoconf.texi (Questions): Rename as...
8847 (Defining Directories): New.
8849 2002-09-09 Akim Demaille <akim@epita.fr>
8851 * doc/autoconf.texi (Making testsuite Scripts): Update.
8852 Suggested by Nishio Futoshi.
8854 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8856 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8857 plain `@' is wanted.
8859 2002-09-09 Akim Demaille <akim@epita.fr>
8861 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8862 `duplicates', since the algorithm was too naive and could keep
8863 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8864 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8865 Reported by Ralf Corsepius.
8866 * tests/torture.at (Configuring subdirectories): Exercise these
8869 2002-09-09 Akim Demaille <akim@epita.fr>
8871 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8872 looking for a replacement file.
8873 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8874 directory is relative.
8875 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8876 directory definition.
8877 Reported by Andreas Schwab and Jim Meyering.
8879 2002-09-06 Akim Demaille <akim@epita.fr>
8881 * doc/autoconf.texi (Setting Output Variables): Clarify what
8882 precious variables are.
8883 Suggested by Pontus Skoeld.
8885 2002-09-05 Akim Demaille <akim@epita.fr>
8887 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8888 (ifnames, autoscan, autom4te): Since we don't only depend on
8889 configure.ac variables (such as VERSION etc.), but also on prefix
8890 and so forth, depend on Makefile, not configure.ac.
8891 Reported by Alexandre Duret-Lutz.
8892 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8894 2002-09-05 Kevin Ryde <user42@zip.com.au>
8896 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8897 doesn't seem to be confined to ia64, just say "some versions".
8899 2002-09-04 Akim Demaille <akim@epita.fr>
8901 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8903 * Makefile.am (maintainer-clean-local): Remove.
8904 (MAINTAINERCLEANFILES): Remove COPYING.
8906 2002-09-03 Paul Eggert <eggert@twinsun.com>
8908 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8909 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8912 2002-09-03 Akim Demaille <akim@epita.fr>
8914 * configure.ac: Bump to 2.53d.
8915 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8916 as of today, on Automake's team suggestion.
8918 2002-09-03 Akim Demaille <akim@epita.fr>
8922 2002-09-02 Akim Demaille <akim@epita.fr>
8924 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8926 * configure.ac: Disable SITE_MACRO_DIR.
8928 2002-09-02 Jim Meyering <meyering@lucent.com>
8930 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8931 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8932 Also, tweak grammar: s/make sure to/be sure to/.
8934 2002-09-02 Paul Eggert <eggert@twinsun.com>
8936 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8937 directory names are generally preferable to physical names.
8939 2002-09-02 Akim Demaille <akim@epita.fr>
8941 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8942 Reported by Raja R. Harinath.
8943 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8944 * bin/autoupdate.in: Use error instead of die.
8946 2002-09-01 Paul Eggert <eggert@twinsun.com>
8948 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8949 ordinary shell concatenation rather than echo+tr+sed command that
8950 runs afoul of a long-line-related sed bug in Solaris 8.
8952 * bin/autoheader.in (parse_args): --warning -> --warnings.
8954 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8955 stdout, as traditional "ls" does.
8956 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8957 _AC_COMPILER_EXEEXT_O): Likewise.
8958 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8960 * bin/autoconf.as: Add --prepend-include option. This patch was
8961 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8962 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8964 * bin/autoconf.in, configure: Regenerate.
8966 * doc/autoconf.texi (Special Shell Variables): Mention
8967 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8969 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8970 MAILPATH and set PS1, PS2, PS4 to default values, to work
8971 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8972 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8973 the Autoconf documentation specifies; fall back to "unset" only if
8974 this fails. Use a shell for-loop for this rather than an m4 loop,
8975 to shorten the output script.
8977 2002-08-30 Paul Eggert <eggert@twinsun.com>
8979 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8980 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8981 for the CDPATH problem. Document PWD.
8982 (Limitations of Builtins): Document the problem that "cd $foo" and
8983 "ls $foo" may refer to different directories in shells conforming
8984 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8985 example, since the old example is now out of date.
8987 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8988 FOO" and "ls FOO" talk about different directories; this catches
8989 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8992 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8993 of rolling our own unset.
8994 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8995 in practice we needn't worry about CDPATH if unset doesn't work.
8997 * Makefile.in, aclocal.m4, bin/Makefile.in,
8998 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8999 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9000 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9001 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9002 tests/Makefile.in: Regenerate with Automake 1.6.3.
9004 * config/config.guess, config/config.sub, config/mkinstalldirs:
9007 * configure: Regenerate with self.
9009 2002-08-30 Kevin Ryde <user42@zip.com.au>
9011 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9014 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9016 * bin/autom4te.in (Request::load): Correctly test for "do" read
9019 2002-08-29 Akim Demaille <akim@epita.fr>
9021 * lib/Autom4te/General.pm (&xqx): New.
9022 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9023 hand, which is not portable.
9025 * bin/autom4te.in: Use them.
9026 Use &error instead of die.
9027 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9030 2002-08-17 Paul Eggert <eggert@twinsun.com>
9032 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9033 default list of compilers to try, since it was long ago superseded
9034 by the ksh fc builtin. Suggested by Steven G. Johnson.
9036 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9038 * doc/autoconf.texi (Invoking autom4te): End the option table,
9039 fixing a bug introduced by the previous patch.
9040 (Limitations of Make): Add a 'target lookup' subentry in the
9041 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9043 2002-07-29 Mark D. Roth <roth@feep.net>
9045 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9046 options and use $AUTOM4TE_PATH.
9047 * doc/autoconf.texi: Remove documentation of autom4te
9048 --include-envvar and --site-macro-subdir options and document
9049 use of $AUTOM4TE_PATH.
9050 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9051 arguments from each language section.
9053 2002-07-29 Paul Eggert <eggert@twinsun.com>
9055 * doc/install.texi: Include copyright symbol in copyright notice.

9350 This improves on an earlier suggestion by H. Peter Anvin.
9352 2002-05-16 Paul Eggert <eggert@twinsun.com>
9354 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9355 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9356 Both macros now accept an optional source-dir arg.
9357 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9359 * NEWS: Document this.
9360 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9362 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9363 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

9373 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9374 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9375 and it causes a 'test' syntax error if it fails.
9376 Bug reported by Stephen Gildea.
9378 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9379 If prototypes are supported, use them to check this at compile-time,
9380 instead of trying to check it at run-time. If we must do a run-time
9381 check, assume that setvbuf is standard when cross-compiling, as
9382 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9383 Bug reported by Paul D. Smith.
9385 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9386 argument specifying location of getloadavg.c. This removes a
9387 FIXME. This idea was taken from Jim Meyering's implementation in
9389 * doc/autoconf.texi (Particular Functions): Document this.
9390 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9391 that's what the code does; this fixes a bug reported by

9396 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9397 autopoint instead of gettextize.
9398 ($uses_alocal): Rename as...
9399 ($uses_aclocal): this.

9409 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9410 files to be 1 second older; just set them to be the same time.
9411 Also, sleep 1 second after the first aclocal, to work around
9412 problems with sub-second time stamps on the input files.
9414 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9416 * doc/autoconf.texi: Mention "set -e -x" lossage

9425 2002-04-29 Akim Demaille <akim@epita.fr>
9427 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9428 of lack of $LINENO support, then the test will compare the $LINENO
9429 in testsuite vs. the lineno in the test file. This is wrong, of
9431 Be sure to protect it.
9432 Reported by Patrick Welche.
9434 2002-04-25 Akim Demaille <akim@epita.fr>
9436 * doc/autoconf.texi (Obsolete Macros): Typo.
9437 Reported by Vladimir Volovich.
9439 2002-04-25 Akim Demaille <akim@epita.fr>
9441 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9442 than some of the input files, hence, on the second run of aclocal,
9443 if some of its input are younger, make them older.
9444 Suggested by Paul Eggert.
9446 2002-04-25 Akim Demaille <akim@epita.fr>
9448 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9454 and ac_subst_vars be sh variables containing the list of
9455 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9457 (_AC_INIT_PREPARE): Use them to log them.
9458 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9459 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9460 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9461 _AC_SUBST_FILES and _AC_SUBST_VARS.

9464 2002-04-24 Akim Demaille <akim@epita.fr>
9466 * bin/autoreconf.in (autoreconf): Run automake after autoconf and

9468 config.h.in that was to be created.
9470 2002-04-23 Akim Demaille <akim@epita.fr>
9472 * bin/autoheader.in (parse_args): --warning takes an argument.

9559 2002-04-12 Akim Demaille <akim@epita.fr>
9561 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9563 2002-04-10 Akim Demaille <akim@epita.fr>
9565 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9566 workaround for ${1+"$@"}.

9568 From Oliver Kiddle and Peter Stephenson.
9570 Have M4sh perform minimal shell sanitizing.
9572 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9574 (_AS_PREPARE): this new macro.
9576 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9577 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9579 Adjust Autoconf and Autotest.
9581 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9582 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9583 * lib/autotest/general.m4 (AT_INIT): Likewise.
9584 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9585 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9588 Use this M4sh to generate Autoconf's shell scripts.
9590 * tests/wrapsh.as: New, precursor of wrapsh.in.
9591 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9592 on Autotest and M4sh.
9593 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9594 (wrapsh.in): New target.
9595 * bin/autoconf.as: New, precursor of autoconf.in.
9596 (autoconf.in): New target.
9598 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9601 with indented comments in rules.

9605 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9606 ac_top_builddir when setting ac_abs_top_builddir.
9608 2002-04-06 Kevin Ryde <user42@zip.com.au>
9610 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9611 (Portable Shell): Cross reference to Systemology.
9613 2002-04-05 Akim Demaille <akim@epita.fr>
9615 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9616 directories when descending in a SUBDIRS.
9617 Reported by Ezra Peisach.
9619 2002-04-04 Andreas Schwab <schwab@suse.de>
9621 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9622 contains no literal separators.
9624 2002-04-03 Akim Demaille <akim@epita.fr>
9626 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9627 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9628 Use dnl, not the KILL diversion.
9630 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9631 (AC_CONFIG_LINKS): here.
9633 Don't use the KILL diversion, as it kills spurious output, which
9634 results in failures being hidden.
9635 Use m4_defn where appropriate.
9636 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9637 after the second argument.
9639 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9640 syntax, as it is provided by M4sugar.

9657 (_AC_COMPILER_OBJEXT): Use them.
9658 Fixes Debian #138666.
9660 2002-04-02 Peter Eisentraut <peter_e@gmx.net>

9665 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9666 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9667 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9669 (AC_C_INLINE): Same.
9670 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.

9678 _AS_MKDIR_P_PREPARE.
9680 2002-03-28 Kevin Ryde <user42@zip.com.au>
9682 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9683 to avoid versions of HP C which don't allow that.
9685 2002-03-27 Paul Eggert <eggert@twinsun.com>
9687 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9688 (AS_SHELL_SANITIZE): Invoke it.
9689 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9691 2002-03-26 Akim Demaille <akim@epita.fr>
9693 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9695 2002-03-26 Akim Demaille <akim@epita.fr>
9697 * doc/autoconf.texi (Introduction): The GNATS base moved.
9699 2002-03-25 Paul Eggert <eggert@twinsun.com>
9701 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9702 as POSIX requires, as it doesn't work with Zsh.
9703 * doc/autoconf.texi (Assignments): Document the problem.
9705 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9707 * doc/autoconf.texi (Limitations of Make): Mention more issue
9708 about VPATH, overriding of macros in sub-makes, and handling of
9711 2002-03-21 Paul Eggert <eggert@twinsun.com>
9713 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9714 problem with here-document buffer boundaries.
9716 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9717 when reinvoking the shell, to work around problems with installers
9718 who put strange things like "cd" commands in their environments.
9720 2002-03-19 Akim Demaille <akim@epita.fr>
9722 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9725 2002-03-19 Akim Demaille <akim@epita.fr>
9727 * bin/autoscan.in (scan_file): Specify the location in `&used'
9731 2002-03-19 Akim Demaille <akim@epita.fr>

9742 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9743 (Limitations of Usual Tools): Add mkdir section.
9745 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9746 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9747 back on AS_DIRNAME to compute prefixes otherwise; this is
9748 roughly what mkinstalldirs does. That way, we need not have
9749 our own filename disassembler. The old disassembler did not
9750 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9752 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9753 Create at_test_all by a series of assignments,
9754 not by a single assignment of a long string. The latter causes ksh
9755 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9756 presumably because of a buffer overrun.
9758 2002-03-14 Paul Eggert <eggert@twinsun.com>
9760 * lib/autotest/general.m4 (at_times_skip):
9761 Renamed from at_times. Now a boolean.
9762 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9763 says 'times: not found'.
9765 2002-03-14 Akim Demaille <akim@epita.fr>
9767 * bin/autoreconf.in (&study_gettextize): New.
9768 (&autoreconf): Handle newest gettextize.
9769 Rerun aclocal if needed.
9770 Suggested by Andreas Schwab.
9772 2002-03-13 Akim Demaille <akim@epita.fr>

9795 does not do it if --with-lispdir is given.

9801 2002-03-08 Akim Demaille <akim@epita.fr>

9804 subdirectory should exist.
9806 2002-03-08 Akim Demaille <akim@epita.fr>
9808 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9810 2002-03-08 Akim Demaille <akim@epita.fr>
9812 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9813 aliases the actual variables, and modifications of the former
9816 2002-03-08 Akim Demaille <akim@epita.fr>
9818 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9819 because of C-c: have m4 output in tmp files, then mv them.
9821 2002-03-08 Akim Demaille <akim@epita.fr>
9823 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9824 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,

9840 2002-03-04 Akim Demaille <akim@epita.fr>
9842 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9843 * lib/autoconf/general.m4 (AC_INIT): More informative error
9846 2002-03-04 Akim Demaille <akim@epita.fr>
9848 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9851 2002-03-04 Akim Demaille <akim@epita.fr>
9853 * doc/autoconf.texi (Transforming Names): Equality between target
9854 and host is irrelevant.
9855 (Specifying Names, Canonicalizing): Remove all references to the
9856 backward compatibility hooks. Rather, collect them all into...
9857 (Hosts and Cross-Compilation): this new section.
9858 * doc/install.texi (System Type): Ditto.
9859 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9860 that `--host' implies cross-compilation.
9862 2002-03-04 Akim Demaille <akim@epita.fr>
9864 * doc/autoconf.texi (Evaluation Macros): New.
9865 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9867 (_m4_foreach): Define the variant with immediate evaluation so
9868 that it contains exactly the items, not an expression which
9869 evaluation is the current item.
9870 (m4_re_string, m4_re_word): Don't over quote them.
9872 2002-03-04 Akim Demaille <akim@epita.fr>
9874 Instead of having stacking `shift's evaluated at the end, let
9875 `foreach' loops immediately evaluate them.
9877 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9878 $*. This is the n-th time I change my mind, but hopefully this is
9881 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9883 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9884 it was only a hack for m4_text_wrap.
9885 (m4_car2): Remove, replaced by...
9887 (_m4_foreach): Adjust.
9888 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9889 m4_bpatsubst for clarification.
9891 2002-03-04 Akim Demaille <akim@epita.fr>

9940 Fix Autoconf PR/207:
9941 AC_PREFIX_PROGRAM fails with dashed program names
9943 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9944 variable when looking for the prefix program.
9945 Now it also works for shell variables.

9955 case/esac, some shells don't support it.
9956 Reported by Zack Weinberg.
9957 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9959 2002-02-06 Akim Demaille <akim@epita.fr>
9961 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9962 sure not to introduce newlines in at_groups.

9977 cross-compilers, too. This undoes some of the most recent change
9980 2002-02-05 Akim Demaille <akim@epita.fr>
9982 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9983 to make sure they are up to date when `check' is run.

10005 optional are the sum of the previous files on the command line'.
10006 Also, pass `--reload-state=' on them, so...
10007 (handle_m4): don't.
10008 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10009 (M4sh): Rely on M4sugar.
10010 (Autotest, M4sh, M4sugar): Use frozen files.
10012 2002-01-31 Akim Demaille <akim@epita.fr>

10020 alphanumeric to `-' instead of `_'.
10022 2002-01-30 Akim Demaille <akim@epita.fr>
10024 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10025 for plain code, the other for cross-compilation code. The latter
10026 is now run with GCC only.

10036 2002-01-29 Akim Demaille <akim@epita.fr>
10038 * tests/torture.at (Configuring subdirectories): Use configure.in,
10039 so that aclocal 1.4 works.

10042 2002-01-28 Akim Demaille <akim@epita.fr>
10044 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10047 2002-01-28 Akim Demaille <akim@epita.fr>
10049 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10050 AUTOTEST_PATH *after* it was set.
10051 Don't put `.' in the PATH: the user should be precise and `./' if
10052 needed. In addition, given that the test suite does some `cd', if
10053 `.' is in the path, the `tested programs' sections will report
10054 programs found in the test suite's directory, while during the
10055 tests (performed in their own directory), these programs are no
10056 longer visible. In other words, the results is confusing and
10058 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

10093 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10094 Reported by Geir Ove Myhr.
10096 2002-01-21 Akim Demaille <akim@epita.fr>
10098 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10100 2002-01-21 Akim Demaille <akim@epita.fr>
10102 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10103 message on invalid options.
10104 * bin/autom4te.in (parse_args): Don't use
10105 Autoconf::General::getopt with non valid options.

10123 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10124 package.m4, since is really depends upon configure.ac, not
10126 * doc/autoconf.texi (testsuite Scripts): Adjust.
10127 * tests/Makefile.am (package.m4): New.
10128 EXTRA_DIST it since its a source.
10130 2002-01-06 Akim Demaille <akim@epita.fr>
10132 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10133 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10134 and PACKAGE_BUGREPORT from here...
10135 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10137 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10138 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10139 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10140 * tests/tools.at (autoheader): Adjust.
10141 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

10149 * doc/autoconf.texi (Output): Improved wording regarding use of
10153 2001-12-18 Kevin Ryde <user42@zip.com.au>
10155 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10156 sometimes needing writable input.
10158 2001-12-17 Jim Meyering <meyering@lucent.com>
10160 * doc/autoconf.texi (New Macros): Tweak wording.
10162 2001-12-14 Akim Demaille <akim@epita.fr>
10164 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10165 trailing files, don't apply `-rf' to files which might not be
10166 created by configure (core, core.*, and *.core), but just `rm -f'.
10167 Suggested by Jonathan Kamens.
10169 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10171 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10173 2001-12-14 Akim Demaille <akim@epita.fr>
10175 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10177 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10179 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10180 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10181 abs_srcdir, top_srcpath to abs_top_srcdir.
10182 (_AC_OUTPUT_FILES): Adjust.
10183 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10184 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10185 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10187 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10189 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10190 C/Fortran linking on HP/UX, by extracting the Fortran library
10191 search path from the LPATH line in the $F77 -v output.
10193 2001-12-12 Kevin Ryde <user42@zip.com.au>
10195 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10196 forbidden file descriptors table.
10198 2001-11-26 Akim Demaille <akim@epita.fr>
10200 * bin/autoscan.in (%c_keywords): Build it at top level.
10201 Map to 1 in order to simplify its uses.
10203 2001-11-26 Akim Demaille <akim@epita.fr>
10205 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10206 Remove $filepath, useless.
10207 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10208 variables, they are really part of the tokens.
10209 Split the input line on spaces and then look for tokens.
10210 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10211 because of `lex$U.$(OBJEXT)'.
10212 (&scan_files): Use "@list" instead of join.
10213 * doc/Makefile.am (CLEANFILES): Add *.fns.
10215 2001-11-26 Akim Demaille <akim@epita.fr>
10217 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10218 Remove, replaced by...
10219 * tests/wrappl.in: Be common for all the Perl executables.
10220 In particular autoscan and autoheader want -I.
10221 * configure.ac: Adjust.
10222 * lib/autoscan/headers: errno.h is portable.
10224 2001-11-26 Akim Demaille <akim@epita.fr>
10226 * bin/autoscan.in (used): New.
10229 2001-11-26 Akim Demaille <akim@epita.fr>
10231 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10233 (&scan_sh_file): Remove a duplicate pattern.
10234 (&check_configure_ac): Use long options.
10235 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10237 2001-11-26 Akim Demaille <akim@epita.fr>
10239 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10240 Before, having a line containing the opening of a multi line
10241 comment made the whole line be ignored.
10243 2001-11-26 Akim Demaille <akim@epita.fr>
10245 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10246 (testsuite Scripts): Be one of its subsection.
10247 (Autotest Logs): New.

10251 Test groups are now run two directories deeper.
10253 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10254 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10256 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10257 top_srcdir, builddir and top_builddir.
10258 Use `at_*dir' relatively to the directory containing the
10259 suite, use `*dir' when relatively to the current group dir.
10261 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10263 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10264 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10265 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10268 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10270 * doc/autoconf.texi (Using System Type): Add an example of `case
10271 $host' usage so people quit using `case $target' everywhere.
10273 2001-11-22 Akim Demaille <akim@epita.fr>
10275 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10276 spotted by Jim Meyering.
10278 2001-11-16 Paul Eggert <eggert@twinsun.com>
10280 This patch implements a `long double' suggestion by Oliver Kiddle.
10282 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10283 static, to catch errors if the value isn't known at compile-time
10284 and the compiler supports dynamic arrays. Change its name from
10285 `_array_' to `test_array' to avoid potential name clashes.
10286 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10287 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10288 better than double. Catch a bug in GCC 2.95.2 x86.
10289 * doc/autoconf.texi (C Compiler): Document the above.
10292 2001-11-13 Akim Demaille <akim@epita.fr>
10294 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10296 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10298 2001-11-13 Akim Demaille <akim@epita.fr>
10300 * lib/autotest/general.m4 (AT_INIT): After having run the test
10301 group, go back to the initial directory, not to at_suite_dir.
10303 2001-11-13 Akim Demaille <akim@epita.fr>
10305 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10306 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10307 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10309 (AT_CHECK_CONFIGURE): Use absolute paths.
10310 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10311 The problem is still the old one: there is no means in M4 (that I
10312 know about) to create a defining macro, because there is no means
10313 to create `$1' etc., therefore, the defining macro ``swallows''
10314 all the arguments meant to the defined macro.
10316 2001-11-13 Akim Demaille <akim@epita.fr>
10318 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10319 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10321 * tests/aclocal.m4: Remove, as it is no longer used.
10323 2001-11-13 Akim Demaille <akim@epita.fr>
10325 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10326 variable names when referring to a single test group, or to
10327 `suite' when referring to the whole test suite.
10328 `at_last_test' is removed: m4 compute at_format itself.
10329 (at_stdout, at_stder1, at_stderr): New variables.
10330 (AT_CHECK): Use them.
10332 2001-11-13 Akim Demaille <akim@epita.fr>
10334 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10336 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10337 Do it as soon as a test fails, don't wait till the end of the test
10339 Don't remove $as_me.[0-9]*, since these files no longer exist.
10341 2001-11-13 Akim Demaille <akim@epita.fr>
10343 * tests/tools.at: Use absolute paths, since we are no longer run
10346 2001-11-13 Akim Demaille <akim@epita.fr>
10348 Now that tests are running in their own private dir, there is no
10349 need to list the files to remove at the end of tests groups.
10351 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10352 (AT_data_files, at_data_files): Remove.
10353 (AT_CLEANUP, AT_DATA): Simplify.
10355 Remove the group dir if !debug && !failed.
10356 * tests/atspecific.m4: Adjust.
10358 2001-11-13 Akim Demaille <akim@epita.fr>
10360 Start a new layout for Autotest: `testsuite' creates
10361 `testsuite.dir' in which the at-check-line etc. files are to be
10362 found, and `testsuite.dir/003' where the test group 3 is run.
10364 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10365 at_check_line_file, at_format, at_test_normalized, at_group_dir
10367 Create the directories.
10368 Use absolute paths for at- files.
10369 (AT_CHECK): Adjust.
10371 2001-11-11 Michael Matz <matz@kde.org>
10373 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10375 (m4_car): Properly quote arguments.
10377 2001-11-13 Akim Demaille <akim@epita.fr>
10379 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10380 with stricter rules on LIBOBJS.
10382 2001-11-12 Paul Eggert <eggert@twinsun.com>
10384 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10385 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10388 2001-11-12 Akim Demaille <akim@epita.fr>
10390 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10392 2001-11-12 Akim Demaille <akim@epita.fr>
10394 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10395 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10396 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10397 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10398 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10399 specify to what the macro should be defined (typically to 1).
10401 2001-11-12 Akim Demaille <akim@epita.fr>
10403 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10406 2001-11-12 Akim Demaille <akim@epita.fr>
10408 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10409 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10410 definition used by Automake where LEX is +/- "${missing} lex" and
10411 `missing' itself contains variables.
10413 2001-11-12 Akim Demaille <akim@epita.fr>
10415 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10416 Now that M4sh pushes BODY, the comments were output at the end of
10419 2001-11-08 Akim Demaille <akim@epita.fr>
10421 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10422 that we can trace macros from aclocal.m4.
10423 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10424 obsoleted, and redirect to the former anyway.
10425 Reported by Ralf Corsepius.
10427 2001-11-08 Akim Demaille <akim@epita.fr>
10429 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10430 processed only if present.
10431 * tests/torture.at (Configuring subdirectories): Use autoreconf
10432 instead of successive calls to autoconf.
10433 Add a nonexistent subdirectory to exercise the patch above.
10434 Reported by Ralf Corsepius.
10436 2001-11-08 Kevin Ryde <user42@zip.com.au>
10438 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10439 doesn't accept .S files.
10441 2001-11-07 Akim Demaille <akim@epita.fr>
10443 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10444 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10445 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10446 * bin/autom4te.in (warn_forbidden): New.
10447 (handle_output): Use it.
10448 Read m4_pattern_forbid with messages.
10450 2001-11-05 Akim Demaille <akim@epita.fr>
10452 * bin/autom4te.in (--normalize): Remove.
10453 * lib/autom4te.in: Adjust.
10455 2001-11-05 Akim Demaille <akim@epita.fr>
10457 * tests/Makefile.am (testsuite): Rename this target as...
10458 ($(TESTSUITE)): this.
10461 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10463 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10464 the --prefix option, also remove it's argument.
10466 2001-11-05 Akim Demaille <akim@epita.fr>
10468 * doc/autoconf.texi (testsuite Invocation): Update.
10469 (Writing testsuite.at): Update.
10471 2001-11-03 Akim Demaille <akim@epita.fr>
10473 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10475 2001-11-03 Akim Demaille <akim@epita.fr>
10477 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10478 (&file_name_is_absolute): New, wrappers around routines from
10480 Use and export them.
10481 (&find_configure_ac): Optionally take a directory where to look at.
10482 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10484 Default @ARGV to `.', not find_configure_ac.
10485 (&autoreconf): Argument is a directory.
10486 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10487 * doc/autoconf.texi (autoreconf Invocation): Update.
10489 2001-11-03 Akim Demaille <akim@epita.fr>
10491 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10492 (@export_forward_subs): New.
10493 Add basename, dirname, and fileparse.
10495 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10496 Don't look for aclocal flags if we already know aclocal is not
10498 Move aclocal.m4t only if it exists.
10499 Reported by Ezra Peisach.
10501 2001-11-03 Akim Demaille <akim@epita.fr>
10503 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10504 passed on command line, defaulting to ./configure.ac if present.
10505 (&maybe_autoreconf, File::Find): Remove, unused.
10506 (&autoreconf): If autoconf is not used, don't try to trace.
10508 2001-11-02 Akim Demaille <akim@epita.fr>
10510 * configure.ac: Bump to 2.52g.
10512 2001-11-02 Akim Demaille <akim@epita.fr>
10516 2001-11-02 Akim Demaille <akim@epita.fr>
10518 * config/config.guess, config/config.sub, doc/standards.texi:
10519 * config/lispdir.m4: Update from masters.
10520 * configure.ac: Bump to 2.52f.
10522 2001-11-02 Akim Demaille <akim@epita.fr>
10524 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10525 Don't run aclocal when aclocal.m4 is not from aclocal.
10527 Don't run libtoolize and gettextize if --install is not given.
10529 2001-11-01 Paul Eggert <eggert@twinsun.com>
10531 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10532 be invoked before _AS_LINENO_PREPARE.
10533 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10534 than character ranges.
10536 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10537 invoking AS_BASENAME. Set the locale variables to 'C' if
10538 possible, as POSIX requires this to get the traditional
10540 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10542 2001-10-31 Paul Eggert <eggert@twinsun.com>
10544 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10545 with {}, as that triggers a bug in Bash 2.05.
10547 (_AS_LINENO_PREPARE): Use Sed rather than
10548 Awk. Fix the sed prepass to work even if there are multiple
10549 instances of $LINENO on the same line. Do not substitute for
10550 other variables like $LINENOT. Do not check file dates; such a
10551 check is unreliable on sufficiently fast machines, and removing
10552 the check makes the code simpler and more reliable. Check for
10553 output and chmod failures.
10555 * doc/autoconf.texi (Special Shell Variables): Document
10558 2001-10-31 Akim Demaille <akim@epita.fr>
10560 * tests/Makefile.am (atconfig): Remove this target, Automake
10563 2001-10-31 Akim Demaille <akim@epita.fr>
10565 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10566 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10567 provided, while it is optional.
10568 * configure.ac: Adjust.
10570 2001-10-26 Paul Eggert <eggert@twinsun.com>
10572 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10573 lib/Autom4te/Struct.pm:
10574 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10577 * doc/autoconf.texi (Special Shell Variables): Document some
10578 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10580 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10581 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

10601 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,

11058 2001-09-22 Akim Demaille <akim@epita.fr>
11060 Rely on `$LINENO' when possible instead of `__oline__'.
11062 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11063 `$LINENO' support replacement when not supported.
11064 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11065 them explicitly to be sure they are not output before this section

11079 2001-09-21 Akim Demaille <akim@epita.fr>
11081 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
11082 Suggested by Jim Meyering.

11100 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11102 be used instead of ':'.
11103 * lib/autotest/general.m4: Replace occurrences of ':' in
11104 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11106 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

11109 arguments. Fixed a typo.
11111 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11113 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11114 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11116 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11118 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

11131 2001-09-19 Akim Demaille <akim@epita.fr>
11133 * lib/autotest/general.m4: Englishoes.
11134 From Tim Van Holder and Alexey Mahotkin.
11136 2001-09-18 Paul Eggert <eggert@twinsun.com>
11138 * doc/autoconf.texi (Common Shell Constructs): New node,
11139 documenting AS_DIRNAME.
11140 (Limitations of Usual Tools): Refer to it when discussing dirname.
11141 Also, update discussion of POSIX standard to reflect latest draft.
11143 * lib/autoconf/c.m4:
11144 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11146 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11147 Do not pass a first argument with leading '-'
11148 to expr, by parenthesizing initial integers that might be negative.
11150 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11151 now merely checks whether it is an error to pass an argument
11154 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11155 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11156 whether it is a (compile-time) error to pass an argument to
11157 getpgrp. This simpler test supports the revised documentation,
11158 and is all that AC_FUNC_GETPGRP's users really need.
11160 2001-09-18 Akim Demaille <akim@epita.fr>
11162 * doc/autoconf.texi (Limitations of Make) <$<>: New.

11172 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11174 Add test for AS_BASENAME.
11175 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11176 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11177 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11178 * tests/base.at: Fixed the expected responses. The old ones were
11180 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11181 the documentation claims it should (and how it behaved in 2.13).
11183 2001-09-18 Akim Demaille <akim@epita.fr>
11185 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11186 the AC_CONFIG_COMMANDS invocation.
11187 This also solves the name clash problems.
11188 Don't set the package's ID.
11189 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11190 No longer to be shipped.
11191 (version.in): Remove.
11192 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11193 * lib/autoconf/status.m4: Adjust.
11194 Use `m4_PACKAGE_STRING'.
11195 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11196 the only optional argument is the name of the test suite.
11197 Expect `package.m4' to define the package signature.
11198 * lib/autom4te.in (Autotest): Add `package.m4?'.
11199 * tests/Makefile.am (package.m4): New.
11200 * tests/suite.at: ifnames is a victim.
11202 2001-09-18 Akim Demaille <akim@epita.fr>
11204 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11205 AC_LIBSOURCE, AC_CONFIG_FILES.
11206 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11207 program version string doesn't match the package's.
11208 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11211 2001-09-17 Paul Eggert <eggert@twinsun.com>
11213 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11214 Allow expression to return any value that can fit into unsigned long
11215 (not int, as before). Check for output errors.
11217 2001-09-17 Bruno Haible <haible@ilog.fr>
11219 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11220 Always include <stdio.h> and <stdlib.h>. Evaluate
11221 the expression in an extra function before these includes. Call
11222 fprintf "%d" only after ensuring the argument is of type 'int'.
11223 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11225 2001-09-17 Paul Eggert <eggert@twinsun.com>
11227 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11228 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11229 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11230 when they don't exist.
11232 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11233 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11236 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11237 version with the version used by fileutils 4.1, except use
11238 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11241 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11243 2001-09-13 Akim Demaille <akim@epita.fr>

11283 * lib/autotest/general.m4 (AT_INIT): Create and remove
11284 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11285 test suites can cohabit.
11287 2001-09-13 Akim Demaille <akim@epita.fr>
11289 * tests/mktests.sh: Don't output banners for empty test files.

11341 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11344 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

11395 2001-09-05 Akim Demaille <akim@epita.fr>
11397 Be ready to handle filenames as stupid as `dnl.at', for if even
11398 the maintainer is dumb enough to do that...
11400 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11401 excellence in M4 quotation: consider `__file__' is active.
11403 And BTW, when invoking m4, pass the --include in the right order:

11484 * man/Makefile.am (.x.1): We really have to pass
11485 autom4te_perllibdir.

11489 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11490 debug scripts, in particular passing explicitly listed tests to

11540 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11541 `autoheader: `config.hin' is created'.
11542 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11544 2001-08-31 Akim Demaille <akim@epita.fr>
11546 * bin/autoheader.in: Rewrite in Perl.

11552 Map --localdir, --autoconf-dir onto it.
11553 Forward autom4te's options instead of interpreting them.
11554 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11555 There is no such envvar since the inception of autom4te.cfg.
11556 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11557 * bin/autoupdate.in: Adjust, and perform more control.

11578 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

11581 find the executables for it.

11583 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11585 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11586 indeed related to running the test suite, while passing

11588 Autoconf executables. So don't do that, leave it to...

11590 * tests/autoscan: New.
11591 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

11610 2001-08-29 Akim Demaille <akim@epita.fr>

12077 autom4te.cache (it's a directory, not a file.
12078 * Makefile.am: Ditto (but maintainer-clean-local).
12080 2001-08-15 Akim Demaille <akim@epita.fr>
12082 * bin/autom4te.in (@m4_warning): New.
12083 (&handle_m4): Use it.
12084 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12085 warnings are issued at each run.
12086 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12087 is in the src tree.
12089 2001-08-15 Akim Demaille <akim@epita.fr>

12164 magic values from an object file when cross-compiling.
12165 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12167 2001-08-10 Akim Demaille <akim@epita.fr>
12169 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12171 Suggested by Russ Allbery.
12173 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12175 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12176 current $prefix to the sub-configures.
12178 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12180 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12181 extension (needed on BeOS). Reported by Guido van Rossum.
12183 2001-08-09 Akim Demaille <akim@epita.fr>
12185 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12187 2001-08-07 Akim Demaille <akim@epita.fr>
12189 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12191 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12192 No need to remove the files before and after the each test, before
12193 each test and at the end of the suite is enough.
12194 Display only the children `times', not the shell's.
12195 If the test failed or was skipped, at-times is not available.
12197 2001-08-07 Akim Demaille <akim@epita.fr>
12199 Always produce testsuite.log, including when there are no
12200 failures. This helps getting information on skipped tests, and
12201 duration of the tests. Err, implement the latter btw.
12203 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12204 Dump information on the first run of each test.
12205 (AT_CLEANUP): Create `at-times' containing the duration of the
12208 2001-08-07 Akim Demaille <akim@epita.fr>
12210 The use of `dumpstat' revealed that `len' was used although it
12211 should not. m4_text_wrap was using it, but in the Autoconf world
12212 where it is legal. Hence (i) test M4sh in its own world, not
12213 Autoconf's, and (ii), ahem, fix the bug :)
12215 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12216 does not like `' instead of [].
12217 (AT_INIT): Forbid `^_?AT_'.
12218 And don't output such tokens.
12219 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12220 `script.as', and `autom4te.cache'.
12221 Remove `empty' and `macro' which are no longer used.
12222 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12223 * tests/m4sugar.at: Use it.
12224 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12226 2001-08-07 Akim Demaille <akim@epita.fr>
12228 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12230 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12232 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12234 2001-08-04 Akim Demaille <akim@epita.fr>
12236 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12237 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12239 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12240 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12241 (AC_F77_MAIN): Likewise.
12243 2001-08-04 Akim Demaille <akim@epita.fr>
12245 Don't rely on M4sugar outputting the patterns in files, since we
12246 might process the output _without_ running m4, hence without these
12249 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12250 * bin/autom4te.in (@Request::includes): Remove, unused.
12251 (@Request::source): Rename as...
12252 (@Request::input): this.
12253 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12254 (&handle_output): Fetch the patterns from the traces.
12255 `$forbidden' and `$allowed' are constant: use m//o.
12256 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12257 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12259 2001-08-04 Akim Demaille <akim@epita.fr>
12261 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12262 autoconf', i.e., in addition to caching traces, cache the output.
12264 * bin/autom4te.in (Request::cache): Rename as...
12265 (Request::id): this.
12266 ($cache, $icache, $tcache, $ocache): New.
12267 (&handle_m4): Save M4 output in the cache instead of $tmp.
12268 (&handle_output): Adjust.
12269 (&up_to_date_p): Check that the output cache is up to date too.
12270 (top level): Run `&handle_m4' iff force or the cache is invalid.
12271 Run `&handle_output' if the output cache is more recent.
12273 2001-08-04 Akim Demaille <akim@epita.fr>
12275 * bin/autom4te.in ($force): New.
12276 (&parse_args, &print_usage): -f, --force is a new option.
12277 (&handle_output): CPP directives might have spaces after `#'.
12278 (&parse_args): The first file only can be frozen.
12280 2001-08-04 Akim Demaille <akim@epita.fr>
12282 Don't let autom4te compute the `include' traces several times:
12283 first check that the trace cache file is up to date, and then
12284 compare its timestamp with that of the output.
12286 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12287 the preamble. Don't require 5.005 as Autom4te::General does it,
12288 and better yet (use `use', not `require'!).
12289 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12290 Class::Struct as Autom4te::Struct.
12291 * lib/Autom4te/General.pm (File::stat): Use it.
12292 (&mtime): New, export it.
12293 * bin/autom4te.in: Use it.
12294 Declare `$req' is invalid if it is outdated.
12295 Don't declare it valid before saving it if something went wrong.
12297 2001-08-04 Akim Demaille <akim@epita.fr>

12300 must be proposed to the users.
12302 * bin/autom4te.in (@required_trace): Remove.
12304 (&parse_args, &print_usage): -p, --preselect is a new option.
12305 (&up_to_date_p): Adjust.

12345 (m4_divert_pop): Dump the whole diversion stack when a diversion
12347 * bin/autom4te.in (&handle_output): Remember of the first
12348 occurrence of a possibly undefined macro, not the last.
12349 Complain about the possibly undefined macros in the same order as
12350 the appear in the output.
12351 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12352 * tests/tools.at (autoconf: forbidden tokens, basic)
12353 (autoconf: forbidden tokens, exceptions): No longer sort
12354 autoconf's stderr, as it is now deterministic.
12355 Check that `dnl' is caught.
12357 2001-08-01 Akim Demaille <akim@epita.fr>
12359 * configure.ac: Bump to 2.52c.

12377 `END', as `Autom4te::General::END' will be triggered.
12378 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12379 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
12380 system to run `mv', `rm', and `cmp'.

12814 cross-language link tests can be performed successfully.
12815 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
