1 2007-05-03 Stepan Kasal <kasal@ucw.cz>
3 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Put a.out first.
4 Reorganize the comments before and in the macro.
6 2007-05-02 Stepan Kasal <kasal@ucw.cz>
8 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
9 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
10 section titles and other comments; no code change.
12 2007-05-01 Kevin Ryde <user42@zip.com.au>
14 * doc/autoconf.texi (Particular Programs): Typo
15 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
17 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
19 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
20 'configure' will fail if the shell lacks proper support for shell
21 functions. Suggested by RMS.
23 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
25 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
26 about Solaris /bin/printf '%010000x' 123. Problem reported by
27 Bruno Haible.
29 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
31 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
32 for a.* when searching for executables, as this prevents users
33 from having files like a.c. Problem reported by Ralf Wildenhues in:
34 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
35 This fixes a problem introduced on 2000-12-19.
37 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
39 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
40 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
41 via Bruno Haible.
43 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
45 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
46 AC_CHECK_TYPE, AC_CHECK_TYPES.
47 * doc/autoconf.texi (Generic types): C types must be type-names
48 (the C terminology), not type-ids (the C++ term). C++ types
49 must not be anonymous.
50 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
51 for C++; this drops support for anonymous struct and union types,
52 which were problematic anyway.
53 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
54 for C++.
56 2007-04-12 Jim Meyering <jim@meyering.net>
58 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".
60 2007-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
62 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
63 to prefer a link source from the build tree, if it exists.

68 * doc/autoconf.texi (Generic Types): Document the restrictions
69 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
70 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
71 with objects too. Document the restrictions on its use.
72 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
73 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
74 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
75 works but the latter doesn't, then it's a valid type.
76 This lets people use function types and so forth.
77 For C++ there doesn't seem to be a simple solution, so leave it alone.
78 (AC_CHECK_SIZEOF): Allow argument to be a variable.
79 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
80 AC_CHECK_TYPE; that wasn't documented or necessary.
82 2007-04-11 Stepan Kasal <kasal@ucw.cz>
84 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
85 when cross-compiling.

97 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
99 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
100 obsolescent. Suggested by Bruno Haible.
101 * NEWS: Document this.
103 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
105 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
106 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
107 default still has the problem. Problem reported by Bruce Korb.
109 2007-03-28 Stepan Kasal <kasal@ucw.cz>
110 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

123 more pitfalls.
125 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
127 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
128 checks for unsigned long long int.
130 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
132 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
133 nonstandard grep R.E. escape sequences.
135 2007-03-17 Jim Meyering <jim@meyering.net>
137 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
138 (Limitations of Usual Tools): Also list \< and \>, and mention that
139 HP-UX's grep, like the one from Solaris, does not support that syntax.
141 2007-03-09 Stepan Kasal <kasal@ucw.cz>
143 * doc/autoconf.texi (Specifying Names): `--host' does not
144 change the build type.
146 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
148 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
149 suggests AC_CONFIG_HEADERS.
150 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
151 AC_CONFIG_HEADERS. Problem reported by
152 Peter O'Gorman.

160 universal binaries. Problem reported by Elias Pipping.
162 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
164 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
165 * doc/autoconf.texi (C Compiler): Document this. There is a new
166 extra argument ACTION-IF-UNIVERSAL.
167 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
168 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
169 Reindent for sanity's sake.
171 2007-02-24 Eric Blake <ebb9@byu.net>

179 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
181 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
182 status of rm so we know when it failed.
183 If cleaning of test dir failed before running the test, warn.
184 Output the line separator in verbose mode before the warning
185 to make clear the warning belongs to the following test.
187 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

196 errors introduced in last change.
198 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
200 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
201 an actual carriage return. Use "ac_cr" to contain the actual
202 carriage return.
203 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
204 with traditional Awk and begin.
205 * tests/torture.at (Limitations of Builtins): Document the problem

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

235 2007-01-31 Eric Blake <ebb9@byu.net>
237 * THANKS (people): Update.
239 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
241 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
242 latest version.
243 (Shell Substitutions): Note problems with @{var:=value} etc.
244 Add a new section for problems with @{#var} etc. Problem noted

248 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
250 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
251 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
252 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
253 substitution will still be done by the special code.
254 Report by Jim Meyering.
256 * doc/autoconf.texi (File System Conventions): Mention that
257 $PATH_SEPARATOR is for the build system only.
258 Report by Keith Marshall.

267 * tests/torture.at (Substitute and define special characters):
268 Test all 8 bit non-NUL characters.
269 Report against Automake by Patrick Welche.
271 2007-01-15 Stepan Kasal <kasal@ucw.cz>
273 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
275 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
277 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
278 early on the reader side, drop stderr of the input to avoid
279 `broken pipe' error output; this may happen even with shell
280 builtin `echo' of some bash versions. Reports by Ian Macdonald
281 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
283 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
285 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
286 separate items of `ac_user_opts', to avoid long lines.
287 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.

295 Fix some wording problems noted by Paolo Bonzini in:
296 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
297 * doc/autoconf.texi (Signed Overflow Examples): Give more
298 discussion about the allow_superuser_privileges example,
299 and change it a bit to make things clearer.
300 (Optimization and Wraparound): Clarify whether the compiler
301 will generate an infinite loop for the example derived from
302 Autoconf's mktime test.
303 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
304 Also, clarify unsigned multiplication overflow.
306 2007-01-04 Eric Blake <ebb9@byu.net>
308 * bin/Makefile.am (RELEASE_YEAR): New macro.
309 (edit): Use it to supply correct copyright year to scripts.
310 * bin/autoconf.as (version): Use it.
311 * bin/autoheader.in ($version): Likewise.
312 * bin/autom4te.in ($version): Likewise.
313 * bin/autoreconf.in ($version): Likewise.
314 * bin/autoscan.in ($version): Likewise.
315 * bin/autoupdate.in ($version): Likewise.
316 * bin/ifnames.in ($version): Likewise.
318 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
320 * doc/autoconf.texi (Integer Overflow): Revised based on today's
321 feedback. The most important changes document what happens when
322 you convert an out-of-range value to a signed integer type, and
323 say that (sum < a) != (b < 0) reliably detects overflow when sum =
324 a + b.
326 * doc/autoconf.texi (Integer Overflow): Greatly expand and
327 rewrite, taking notions from the recent discussion on the gcc and
328 autoconf mailing lists; please see
329 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
330 and follow the many links.
331 (Integer Overflow Basics, Signed Overflow Examples):
332 (Optimization and Wraparound, Signed Overflow Advice):
333 (Signed Integer Division): New sections.
335 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
337 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
338 preprocessor macro arguments in traced name.
339 * doc/autoconf.texi (Defining symbols): Document longstanding
340 support for AC_DEFINE-ing macros with arguments, and document
341 behavior when the same variable has multiple AC_DEFINEs.
342 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
343 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
344 macros directly, giving much shorter and simpler code.
346 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
348 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
349 space before "$ac_configure_args" to prevent a 'config.status
350 --recheck' failure if ac_configure_args doesn't contain a leading
351 space. This works around a problem with the XEmacs configure.ac,
352 which uses the (undocumented) ac_configure_args variable
353 inconsistently with Autoconf.
355 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
357 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
358 Include <limits.h>, and use its INT_MAX to rewrite the
359 j loop so that it does not overflow 'int'. Problem reported by
360 Ralf Wildenhues in
361 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
362 Play it safe by shifting left by 1 rather than multiplying by 2,
363 as GCC is less likely to optimize this away when the value
364 is signed (when it assumes overflow leads to undefined behavior).
365 Also, don't assume time_t uses two's complement.
367 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
369 * tests/torture.at (Substitute a 2000-byte string): Avoid using
370 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
371 dumps core on it. Report by Tim Rice.
373 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
375 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
376 --disable-option-checking to --help output even when
377 AC_PRESERVE_HELP_ORDER is not used.
378 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
379 --with argument, rather than argument with [-.] replaced by
380 underscores.
381 * NEWS: Fix typo in previous change; the news was in the
382 wrong section.
384 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
386 * NEWS: Warnings are now generated by default for unknown
387 --enable-* and --with-* options.
388 * doc/autoconf.texi (Option Checking): Renamed from
389 (Configure Option Checking). Tighten up the wording a bit.
390 (External Software, Package Options): Cross-reference to Option
391 Checking, and use this to shorten our section.
392 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
393 "$x" to test "x$foo" != x.
394 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
395 Don't warn if $enable_option_checking is "no".
396 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
397 ac_unrecognized_opts to the empty string.
398 Don't echo the unrecognized opts, as this might mishandle
399 backslashes or leading -.
400 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
401 usage next to the other --disable-FEATURE options in the
402 help string.
404 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
406 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
407 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
408 Print warning for unrecognized --with and --enable options
409 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
410 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
411 Disable option checking when subdirs are configured.
412 (AC_OUTPUT): If warnings are enabled, print warning about
413 unrecognized --with and --enable options at the end of
414 the configure output (as well as at the beginning).
415 * doc/autoconf.texi (Option Checking): New node.
416 Document new option warning functionality.

423 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
425 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
426 Define HAVE_GETMNTENT to 1, not to the empty string.
427 Problem originally reported by Jochen Friedrich in
428 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
430 This change prompted by a problem report by Andrey Simonenko in
431 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
432 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
433 object-like macros only, in the traditional portable character
434 set.
435 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
436 Warn about attempts to define things that are not identifiers.
437 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
438 awful hack that AC_DEFINEd macro names containing parentheses.
440 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
442 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
443 too drastic, even if Texinfo in theory requires it for info mode.
445 (config.status Invocation): Renamed back from Recreating a
446 Configuration).
447 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
448 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
450 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>

455 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
457 * NEWS: Document changes with echo and printf, and the lack
458 of limits on the total size of multi-line values of substituted
459 variables, and the AC_FUNC_FSEEKO fix.
461 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
463 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
464 Writing configure.ac.
465 (Autoconf Input Layout): Renamed from configure.ac Layout.
466 (Recreating a Configuration): Renamed from config.status Invocation.
467 (Obsolete Recreation): Renamed from Obsolete config.status Use.
468 (acconfig Header): Renamed from acconfig.h.

470 (Writing Testsuites): Renamed from Writing testsuite.at.
471 (Autom4te Cache): Renamed from autom4te.cache.
473 * BUGS: Remove mention of VPATH problem, since it's now documented
474 not to be a bug in the Autoconf build procedure itself, but rather
475 a problem with the proprietary `make' programs.
477 * doc/autoconf.texi (Build Directories): Add a cross reference
478 to VPATH and Make.
480 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
481 * doc/standards.texi: Sync from gnulib.

485 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
486 generated automatically.

490 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
491 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
492 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
494 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
496 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
497 `CEOF$ac_eof' special marker, the awk script cannot contain a
498 line matching `^CEOF', so this is not needed any more.
499 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
500 special marker in the test.
502 2006-12-06 Stepan Kasal <kasal@ucw.cz>
504 * tests/tools.at (autom4te preselections): Use `find -newer';
505 remove one of the sleeps.
507 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
508 more readable, using ...
509 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
511 * doc/autoconf.texi (autoheader Invocation): Do not double-
512 quote the parameter of `AH_BOTTOM' in the example.
514 2006-12-05 Stepan Kasal <kasal@ucw.cz>
516 * doc/autoconf.texi (Configuration Headers): Remove the
517 example with multiple input files.
518 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
519 multiple input files.
521 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
523 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
524 creating the awk substitution script, handle one input line at a
525 time, so that the maximum length of a substituted (multi-line)
526 value is not limited by the size of the sed pattern space.
527 The trade-off is a slightly repetitive sed script.
528 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
529 can only have up to 7 characters, due to Solaris 10 /bin/sed.
530 * tests/torture.at (Substitute a 2000-byte string): Increase the
531 test with several long lines, they should not be caught by sed
532 limits any more.
534 * tests/tools.at (autom4te preselections): New test, to flag
535 entries missing from autom4te.cfg.
536 Report by David Byron <dbyron@hheld.com>.
538 * tests/torture.at (Substitute a 2000-byte string): Actually use
539 AC_PROG_AWK, so the last change works as intended.
540 (Substitute and define special characters): Likewise.
541 (Substitute a newline): Likewise.
543 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
544 instead of `awk' consistently.
545 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
546 * tests/torture.at (Torturing config.status): Test both the
547 result of AC_PROG_AWK and plain awk.
548 (Substitute a 2000-byte string): Likewise.
549 (Substitute and define special characters): Likewise.
550 (Substitute a newline): Likewise.
552 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
554 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
555 can be assigned to a function pointer. Problem reported by
556 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
557 part of a patch by Ralf Wildenhues in that same bug report.
559 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
561 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
562 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
564 2006-12-01 Eric Blake <ebb9@byu.net>
566 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
567 cross-compiling from cygwin to mingw.
568 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
569 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
570 to lib/autoconf/c.m4.
572 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
574 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
575 string for more reliable failure. Wrap the entire test that
576 causes the broken Solaris printf to dump core, in a subshell,
577 so the segmentation fault message is reliably suppressed.
578 Fix shell expansion errors by using /usr/ucb/echo always;
579 avoid an error on systems without it by another subshell.
580 Avoid m4 expansion of `$1'. Set the zeroth argument of the
581 subshell-$as_echo to `as_echo', for better error message.
583 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
585 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
586 `BASH_SOURCE' contain a newline, set them to empty, as they may
587 not be unset.
589 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
591 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
592 years and is too hard to maintain now. The last straw was
593 reported by Jerker Baeck in
594 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
595 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
596 * doc/autoconf.texi (Particular Functions): Move
597 AC_FUNC_SETVBUF_REVERSED from here...
598 (Obsolete Macros): ... to here. Say that it does nothing now.
599 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
600 Turn into (almost) a no-op.
602 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
603 (AC_C_VOLATILE):
604 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
605 These macros are obsolescent and new applications shouldn't need them.
606 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
607 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
608 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
609 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
610 (AC_FUNC_VPRINTF): Likewise.
611 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
612 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
613 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
615 * doc/autoconf.texi (Setting Output Variables): Mention that
616 @VAR1@VAR2 has unspecified behavior. Problem reported by
617 Ralf Wildenhues.
618 * NEWS: Mention this.
620 * Makefile.am: Put only a single '#' into the copyright notice,
621 so that it's also present in the output file. Standardize wording
622 in makefile copyright notices to match GNU coding standards.
623 * bin/Makefile.am: Likewise.
624 * doc/Makefile.am: Likewise.
625 * lib/Makefile.am: Likewise.
626 * lib/freeze.mk: Likewise.
627 * lib/autoconf/Makefile.am: Likewise.

630 * lib/m4sugar/Makefile.am: Likewise.
631 * man/Makefile.am: Likewise.
632 * tests/Makefile.am: Likewise.
633 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
634 one-line file.
636 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
638 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
639 in the sed script that mangles the awk script: delete up to the
640 first exclamation mark only.
641 * tests/torture.at (Substitute and define special characters):
642 Test '!' too.
644 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
646 Rewrite config files generation: avoid quadratic growth in
647 the number of substituted variables by using awk instead of sed
648 for the bulk of the substitutions.
649 * NEWS: Mention this.
650 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
651 forbidden in the output (and thus input) file.
652 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
653 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
654 generate just one large awk script for substitutions,
655 eliminating much of the earlier complexity, while adding some
656 new complexity. Only expand the substitution templates at
657 configure time, for smaller configure script size. If
658 _AC_SUBST_FILES are used, test 'awk' for working getline support
659 at config.status time. If absent, interpolate through the
660 shell. The awk script was written with much help
661 from Paolo Bonzini and Paul Eggert.
662 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
663 (_AC_SED_FRAG_NUM): Likewise.
664 (_AC_SUBST_CMDS): Renamed from...
665 (_AC_SED_CMDS): ...this.
666 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
667 * tests/torture.at (Substitute a 2000-byte string): Also
668 substitute a line with 1000 words, and a variable with several
669 long lines.
670 (Substitute and define special characters): Test awk special
671 characters, and put substitution input strings `@foo@' in the
672 output, to test that no recursion happens; test several other
673 combinations from Paolo Bonzini.
675 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
677 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
678 that replaced echo with AS_ECHO where this wasn't necessary.
679 Problem reportd by Ralf Wildenhues.
680 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
681 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
682 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
684 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
686 * lib/freeze.mk (GREP): Removed, no need to initialize this.
688 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
690 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
691 that traditional Awk lacks 3-arg "split". It has it.
692 Mention that FS must be a single character, and a few other
693 99-byte limits of traditional Awk.
694 Mention that if (i in a) doesn't work with traditional Awk.
696 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
698 * tests/autotest.at (BSx641-newline in command):
699 (BS-BS-newline in command, BSx640-newline in command):
700 (Newline-CODE-BS-newline in command):
701 (Single-quote-BS-newline in command):
702 (Single-quote-newline-BS-newline in command):
703 Use printf '%s\n' instead of echo, for portability to hosts
704 where echo interprets backslashes. This will break on hosts
705 that lack printf, but for now let's assume all such hosts
706 are dead (if not, we should get reports of test failures).
708 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
710 'echo' has some portability problems, when given a first argument
711 with a leading '-', or when given any argument containing '\'.
712 Avoid using 'echo' in these cases.
713 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
714 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
715 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
716 * lib/autotest/general.m4 (AT_INIT): Likewise.
717 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
718 argument might be unportable.

736 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
737 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
738 * bin/autoconf.as: Redo verbose flag implementation, as the old
739 scheme wouldn't work with AS_ECHO.
740 * lib/autotest/general.m4 (AT_INIT): Likewise.
741 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
742 Don't use ECHO_T, since ECHO_N is now reliable.
743 * lib/autotest/general.m4 (AT_INIT): Likewise.
744 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
745 rather than using a here-document to put the script into a file.
746 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
747 use AS_ECHO.
748 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
749 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
750 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
751 bug, but we might as well stop using ECHO_N and ECHO_C internally.
752 * lib/autotest/general.m4 (AT_SETUP): Likewise.
753 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
754 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
755 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
756 operand, as AS_ECHO requires. Avoid double file name expansion.
757 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
758 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
759 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
760 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
761 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
762 Double-quote strings that would otherwise contain M4 comments.
763 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
765 * configure.ac (AC_INIT): Bump to 2.61a.
766 * NEWS: Likewise.
768 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
770 Version 2.61.
772 * configure.ac (AC_INIT): Bump to 2.61.
773 * NEWS: Likewise.
775 * tests/autotest.at (Macro with backslash in a test title):
776 Comment out for now, as this tests neither fails nor passes
777 reliably. Problem reported by Ralf Wildenhues.
779 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
781 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
782 in previous change, which caused test failures.
784 2006-11-16 Stepan Kasal <kasal@ucw.cz>
786 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
787 code for --enable, --disable, --with, and --without to...
788 (_AC_INIT_PARSE_ENABLE): ... a new macro.
789 * doc/autoconf.texi (Package Options):
790 * NEWS: Document that AC_ARG_ENABLE allows dots, too.

856 benefit of platforms like Solaris+GCC where it is common to have a
857 non-working g++ installation.
859 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

867 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
869 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
870 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
871 Imported from a similar patch to gnulib by Bruno Haible.
873 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
875 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

877 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
878 New macros, taken from gnulib.
880 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

891 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
892 and Stepan Kasal <kasal@ucw.cz>
894 Handle special characters in test case titles correctly.
895 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
896 properly.
897 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
898 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
899 argument. Extend to check titles printed by ./micro-suite and
900 ./micro-suite -l and the title in micro-suite.log.
901 (Backquote in a test title,
902 Single-quote in a test title,
903 Double-quote in a test title): Don't expect failure anymore.
904 (Backslash in a test title): Put a non-whitespace character after the
905 backslash so that Bourne shells might actually see it as an escape
906 sequence.
907 (Brackets in a test title,
908 Pound in a test title,
909 Comma in a test title,
910 Quoted Macro in a test title,

913 (Macro with backquote in a test title,
914 Macro with double-quote in a test title,
915 Macro with backslash in a test title): New tests expected to fail.
916 * tests/torture.at (#define header templates): M4-quote this title in
917 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
918 The visible effect was a stray [] in the testsuite output.
920 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
922 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
923 `trap ... 0' inside a function, for AIX sh.
925 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
927 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
928 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
929 5363) simply issues a warning when dividing by zero at compile
930 time. Problem reported by Elias Pipping.
932 2006-10-26 Eric Blake <ebb9@byu.net>
934 * THANKS: Update.
935 * doc/autoconf.texi (Evaluation Macros): Improve the example to
936 show effect on macros that expand with commas.
937 Reported by Joel E. Denny.
939 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
940 Also work with M4 1.4.8.
942 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
944 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
945 Jim Meyering.
947 2006-10-25 Stepan Kasal <kasal@ucw.cz>
949 * tests/tools.at (autom4te --force): New test, verifies that
950 `--force' always rewrites the output file.
952 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
954 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

961 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
963 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
964 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
965 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
966 reported by Nelson H. F. Beebe for Coreutils 6.4.
968 * tests/tools.at (autoconf --trace: user macros): Remove test
969 for tracing multiline macros, since m4 1.4.7a uses a different
970 way to number lines. Problem reported by Ralf Wildenhues.
972 2006-10-24 Stepan Kasal <kasal@ucw.cz>
974 * bin/autom4te.in (handle_m4): Do not redirect stdin to
975 /dev/null since the heuristics for interactive behaviour was
976 fixed in CVS m4.
978 * bin/autom4te.in: With --force, always refresh the output
979 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
981 * bin/autoconf.as: Fix the verbose message at the end.
983 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

998 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
999 AC_CACHE_CHECK_INT, since it's no longer public.
1000 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1001 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1003 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1005 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

1021 Standards.

1031 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1032 looking for special shell characters.
1033 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1034 macro defined by AS_VAR_PUSHDEF before passing it as a
1035 parameter.
1036 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):

1046 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1048 (Imported from Automake.)
1049 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1050 which incorrectly sets the mode of an existing destination
1051 directory. In some cases the unpatched install-sh could do the
1052 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1053 system. We hope this is rare in practice, but it's clearly worth
1054 fixing. Problem reported by Alex Unleashed in
1055 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1056 Also, don't bother to check for -m bugs unless we're using -m;
1057 suggested by Stepan Kasal.
1059 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1061 Import this change from Automake:
1063 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

1065 is enabled by default with gnu and gnits strictness.
1066 Report from Bruno Haible.
1068 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1069 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1070 gnu and gnits modes.
1072 Import this change from Config:
1074 2006-09-20 Ben Elliston <bje@gnu.org>

1077 Import this change from Gnulib:
1079 2006-09-16 Karl Berry <karl@gnu.org>
1080 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1081 to avoid sectioning errors.
1083 Import these changes from Texinfo:
1085 2006-10-04 Karl Berry <karl@gnu.org>
1086 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
1087 (\quoteexpand): rename to \rquoteexpand.
1088 (\codequoteleft): new def, to look for @set codequotebacktick.
1089 (\lquoteexpand, \quoteexpand): new defs.
1090 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
1091 (\code): must use new \...Char values, since now ` is active.
1093 2006-08-26 Karl Berry <karl@gnu.org>
1094 * build-aux/texinfo.tex (\textdegree): New command.
1096 2006-08-12 Karl Berry <karl@gnu.org>

1101 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1103 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1105 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1106 added to the template can get mangled.
1108 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1110 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1111 include the default headers, and redefine obstack_chunk_alloc
1112 and obstack_chunk_free. Fixes false failure with glibc.
1114 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1116 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1117 for backward compatibility with Libtool 1.5.22. Problem reported
1118 by Ralf Wildenhues.
1120 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1123 AC_PROG_CC.
1124 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
1126 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1128 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1129 the NonStop platform.
1130 * doc/autoconf.texi (Posix Variants): Likewise.
1131 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1133 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1134 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1135 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1136 Use a better substitute, by inspecting the output of "ls"
1137 rather than just using ":".
1138 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1139 rather than AS_EXECUTABLE_P, since we needn't worry about
1140 non-regular files here.
1142 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1143 due to configuration hassles with this. See Tonya Underwood's report
1144 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1145 * doc/autoconf.texi (Special Shell Variables): Likewise.

1151 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1153 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1155 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1156 initialization which is not inherited through the environment
1157 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1158 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1160 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1162 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1163 problems with mkdir -p -m.
1165 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1167 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1168 comment about ac_cpp_err; it was incorrect, and anyway
1169 ac_cpp_err is being removed below.
1170 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1171 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1172 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1173 nobody uses it.
1174 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1175 with werror_flag and conftest.err and so forth. This is more
1176 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1177 and anyway the user shouldn't normally want to see this gorp logged.
1178 Problem reported by Ralf Wildenhues.
1179 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1180 empty, not 'no', since the rest of the code uses 'test -z'.
1182 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1184 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1185 Use a single call to AC_DO_TOKENS rather than multiple, for
1186 efficiency.
1187 (_AC_LINK_IFELSE): Test that resulting file is executable.
1188 Problem reported by mwoehlke in
1189 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1191 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1192 than creating a file to use with test -x; this is much faster.
1194 2006-10-02 Bruno Haible <bruno@clisp.org>
1196 * lib/autom4te.in (Automake-preselections): Add
1197 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1199 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1201 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1202 standard error, `experr' should be used, not `expout'.
1204 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1206 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1207 fseeko testing program twice; just use the earlier result.
1208 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1209 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1210 still doesn't let the program compile.
1211 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1212 failed.
1214 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1215 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1216 include it, without including anything else.
1217 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1218 expressions.
1219 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1221 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1223 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1224 `error.h', and include it, for a `error_at_line' prototype.
1225 Use a nonempty format string in the link test.
1226 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1227 for a declaration of wait3.
1229 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1231 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1232 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1233 can apply to constants too, and that it checks for macro defns.
1234 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1235 and simply cast the identifier to void. This handles structure
1236 values. Problem reported by Ralf Wildenhues.
1237 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1239 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1241 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
1242 structure, and function symbols.
1244 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1246 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
1247 member.

1261 present.

1292 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
1293 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1294 --error-output, to avoid warnings with M4 2.0.
1296 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1298 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

1309 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1310 mistaken comment: the path has to be relative; do not use
1311 the path at runtime.
1313 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1315 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

1319 for both changes.
1320 * doc/autoconf.texi (Setting Output Variables): Fix example to
1321 not show `--silent' being passed to a `configure' re-run.
1323 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1325 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1326 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1327 for the existence of the directory at configure-time. That's
1328 too late, anyway. Problem reported by Stefan Seefeld.
1330 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1331 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1332 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1334 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1336 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1337 works with GNU M4 1.4.3 again; make the normalized form
1338 match the current m4 message; fix the description.
1339 * test/tools.at (autom4te cache): Adapt to the change.
1341 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1343 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1344 to catch glibc bug 2821
1345 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1347 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1348 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1349 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1350 assume C89.
1352 2006-09-08 Stepan Kasal <kasal@ucw.cz>
1354 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

1372 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1373 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1374 accept files with extension `.f'. For consistency, also prefer
1375 xlf over f77.
1376 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1377 from last patch.

1394 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1396 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1397 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1398 except the first two arguments are reversed.
1399 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1400 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1401 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1402 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1403 equivalent to the old AC_COMPUTE_INT.
1404 (AC_COMPUTE_INT): No longer caches or reports. New signature.

1411 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1412 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1413 programs should use their Gnulib counterparts.
1414 * doc/autoconf.texi (Particular Functions): Likewise.
1415 (Macro Names, testsuite Invocation): Replace uses of these
1416 obsolete macros with uses of non-obsolete macros.

1444 Fix Lex library problem reported to us by Julio Garvia.
1445 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1446 for the default, which the user can override.
1447 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1448 deal with LEXLIB.
1449 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1450 didn't work if some values were cached but not others. Test for
1451 broken lex libraries like native ia64-hp-hpux11.22; see
1452 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1453 work around the problem by preferring an empty LEXLIB to -lfl or
1454 -ll. Let the user set LEXLIB='' to indicate no library needed.
1456 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1457 * README: Likewise.

1559 * doc/autoconf.texi (Particular Programs): Mention that
1560 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1561 Reported by Alexandre Duret-Lutz.
1563 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1565 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1566 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1567 Bill Northcott in
1568 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

1583 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1584 * doc/autoconf.texi (Header Templates, Default Includes):

1599 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1600 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1601 this.
1603 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1605 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1606 problems with arg script text that doesn't end in newline, and

1609 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1611 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

1621 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1622 --help' should mention that `--version' outputs configuration
1623 settings. Report by Bruno Haible.
1625 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1627 Fix test suite failures reported by Pierre in
1628 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

1643 less skeptical about "volatile", after discussion with
1644 Bruno Haible on bug-gnulib.
1645 (Limitations of Usual Tools): Warn about sed stripping
1646 leading white space from text. From Bruno Haible.
1648 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1650 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1651 compiler complains about it, even if things works after the
1652 complaint. Problem reported by Peter O'Gorman.
1654 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1655 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1656 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1658 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1660 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1668 to match M4 1.4.5.
1670 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1672 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1673 under AC_C_VOLATILE.
1674 (Volatile Objects): Be a little less skeptical about what
1675 "volatile" means. Derived from thoughts by Ben Pfaff in
1676 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1678 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1680 * doc/autoconf.texi: Fix some typos.
1682 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1684 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1685 more globally, since the 2006-06-30 patch didn't suffice. Problem
1686 reported by Keith Marshall. Also, don't bother with builddir2,
1687 since it shouldn't be needed any more.
1689 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1691 * doc/autoconf.texi (Generic compiler characteristics):
1692 Document AC_COMPUTE_INT. Fix wrong statements on Default

1706 * NEWS: Document previous change.
1708 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1710 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1711 Require that long long int be at least 64 bits wide. C99 requires
1712 this and enough programs depend on it so we should check for it.
1713 Bruno Haible reports in
1714 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1715 that long long int is 32 bits wide with some nonstandard compilers.
1716 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1718 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1720 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1721 to a nonexistent file, so that we don't have to worry about
1722 a local site configuration that doesn't use /usr/local.
1723 Problem reported by Keith Marshall in
1724 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1726 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1728 * doc/autoconf.texi: Be more consistent about using @acronym with
1729 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1730 quite right (it talked about "OSF/Tru64", even though the
1731 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1732 and it even mentioned "OSF 4"!) and at this point there's little
1733 reason to talk about OSF any more, since it died in 1994.
1734 (Specific Compiler Characteristics): Simplify example of
1735 negative-size array.
1736 (File Descriptors): Reorder to make the text flow better.
1737 Remove joke about "appreciate the various levels"; I didn't get it.
1738 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1739 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1740 (File Descriptors, Limitations of Usual Tools):
1741 Tone down the advice against renaming or removing open files.
1742 (Limitations of Usual Tools): Add a new section, on 'rm'.
1744 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1746 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1747 -lXt in LIBS, idea from Karsten Hopp; this was due since
1748 this change:
1750 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1751 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1752 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1753 (which belong to Xt, not X itself). See Debian bug 327655.
1755 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1757 * configure.ac (AC_INIT): Bump to 2.60a.

1771 quadrigraph correctly in traces.
1773 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1774 Fix typos.
1776 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1777 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1778 not defined.
1779 * doc/autoconf.texi (Changed Directory Variables): New node,
1780 to document the whole `datarootdir' business a bit better.
1781 * NEWS: Update.
1782 * tests/torture.at (datarootdir workaround): Extend test.
1783 Prompted by report by Alexandre Julliard.
1785 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1787 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

1789 fix reported by Larry Jones.
1791 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1793 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1794 about literal '${datarootdir}' if a definition is found in the
1795 output file.
1797 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1799 * NEWS: Use "M4" rather than "m4" when appropriate.
1800 Problem reported by Eric Blake.
1801 * doc/autoconf.texi: Likewise.
1802 Use @acronym around BSD, GCC, and GNU when appropriate.
1803 (Why GNU M4): Renamed from "Why GNU m4".
1804 (Redefined M4 Macros): Mention that Posix
1805 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1806 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1807 to int.
1809 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1811 * bin/autom4te.in (handle_output): Do not forbid the empty
1812 pattern.
1813 * tests/tools.at (autoconf: the empty token): New test.
1815 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1817 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1818 calls, so that we do not care whether they are LIFO or FIFO;
1819 in the m4_wrap, do not check which diversion is the topmost
1820 one, just check that the stack is balanced at the end.
1821 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1822 base diversion forever--pop the previous diversion before
1823 opening the new one; consequently, remove the m4_wrap call.
1824 * lib/autotest/general.m4 (AT_INIT): Likewise.
1825 * tests/m4sugar.at: Do not use
1826 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1828 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1829 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1831 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1832 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1833 Rework example of m4wrap token-pasting trouble so that it doesn't
1834 care whether it's LIFO or FIFO.
1835 Fix some "contrary to"s that are awkward in English.
1837 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1839 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1840 to `yes' instead of `int$1_t' if the type is found, for more
1841 consistent configure output (where $1 is the number of bits).
1842 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1843 Suggested by Bruno Haible.
1845 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1846 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1847 with system headers. Report by Bruno Haible.
1849 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1851 * config/config.guess, config/config.sub: Sync from upstream.
1853 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1854 in order to avoid picking up an older installed frozen m4sh.m4f.
1855 Besides an outdated shell startup, this could have been created
1856 by an earlier M4 version with incompatible frozen file format.
1858 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1860 * README: Recommend m4 1.4.4 instead of 1.4.3..
1861 * doc/autoconf.texi: Likewise.
1862 (Special Chars in Names): Say that $(.FOO) is portable, as
1863 suggested by Stepan Kasal.
1864 (Installation Directory Variables, Build Directories):
1865 (Automatic Remaking, Subdirectories, Fortran Compiler):
1866 (Making testsuite Scripts, Defining Directories):
1867 Quote variable usages better.
1868 (Making testsuite Scripts): Add clean-local rule to makefile
1869 snippet, by Eric Blake.
1870 (Installation Directory Variables): Fix table item font.
1871 Reword slightly to clarify. Generalize advice about
1872 not using special characters to include all file-related
1873 vars, not just VPATH.
1874 (Special Chars in Variables): Warn about special characters in
1875 $(srcdir) too.
1876 (Assignments): Clarify default-value example as suggested by
1877 Ralf Wildenhues in
1878 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1879 (Special Shell Variables): Note leading ./ or ../, as suggested
1880 by Eric Blake.
1881 (Limitations of Builtins): Under cd, warn about CDPATH.
1882 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1883 Ralf Wildenhues.
1885 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1887 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1888 `@var', for texi2html.
1889 (Systemology): Some more word wrapping, for DVI output.
1890 (autom4te Invocation): The short option for `--melt' is `-M',
1891 not `-m'.
1893 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1895 * doc/autoconf.texi: More formatting and English tweaks,
1896 many suggested by Ralf Wildenhues.
1897 Reword to avoid "@code{...}'s" and the like, since it's ugly
1898 with Emacs info mode. discontents -> woes.
1899 Put a few "will"s back. time stamp -> timestamp.
1900 side-effect -> side effect.
1902 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1904 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1905 Warn about $@ not persisting. Problem reported by Julien Danjou in
1906 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1907 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1908 Mention other special chars, too.
1910 2006-06-14 Eric Blake <ebb9@byu.net>
1912 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1914 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1916 * doc/autoconf.texi: Some systematic minor improvements, as
1917 follows. Use "makefile" when talking about makefiles
1918 generally (which might be named "makefile" or "Makefile" or even
1919 "foo.mk"), "Makefile" when talking about a specific makefile
1920 called "Makefile". This unclutters the text from weird quotes
1921 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1922 values" rather than "@var{foo}s" and similar constructs containing
1923 "}s". Use "Make rules" rather than "Makefile rules". Minor
1924 English-language improvements. Change the prefix "sub-" to "sub"
1925 and "re-" to "re".
1926 Put blank lines around examples more consistently.
1927 Avoid "rather" and "very" as intensifiers.
1928 Avoid "will" as an auxiliary.
1929 (Limitations of Make): Split this node into....
1930 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1931 (Leading _ in Macro Names, Backslash-Newline-Newline):
1932 (Backslash-Newline Comments, Long Lines in Makefiles):
1933 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1934 (obj/ and Make, make -k Status, VPATH and Make):
1935 (VPATH and Double-colon, $< in Explicit Rules):
1936 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1937 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1938 New nodes, resulting from splitup of Limitations of Make.
1939 All cross-references changed. Raise the top node from
1940 a section to a chapter, and all subnodes accordingly.
1941 Redo the introductory wording to match the new organization.
1942 (Installation Directory Variables): Use an example that is
1943 closer to what Autoconf actually does. Mention that VPATH's
1944 value should not contain metacharacters or white space.
1945 (Fortran Compiler): Fix a VPATH bug in an example.
1946 (Leading _ in Macro Names): Mention that this problem is no longer
1947 of practical concern.
1948 (VPATH and Make): Reword the advice to make it clearer
1949 that Autoconf and Automake support VPATH in non-GNU make, but
1950 many packages have bugs in this area.
1951 ($< in Explicit Rules): Refer to Build Directories rather
1952 than using a (non-VPATH-safe) example.
1953 (Automatic Rule Rewriting): Mention the sort of disaster that
1954 can ensue with Solaris-style rule rewriting with VPATH.
1956 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1958 * doc/install.texi (Compilers and Options): Weaken the
1959 suggestion to use GNU make for VPATH builds.
1961 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1962 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1964 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1965 in regular expression.
1967 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1969 * doc/autoconf.texi (Installation Directory Variables):
1970 Drop extra @samp from `@table @samp' item.
1971 (Limitations of Usual Tools): Comment fix.
1972 Do not nest @samp just to point to other table items.
1973 (Writing testsuite.at) <AT_CHECK>: The second argument to
1974 `@dvar' is already @samp'ed.
1975 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1976 do not use @var in the second argument.
1978 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1980 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1981 $as_shell.exe too. Problem reported by Andreas Buening in
1982 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1984 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1986 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1987 `unused variable' compiler warning, for `-Wall -Werror'.
1988 Reported by Jaap Haitsma in
1989 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1991 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1993 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1994 case the compiler dumps core. Problem reported for
1995 OpenServer 5.0.7 by Tim Rice in
1996 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1997 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1998 Likewise.
2000 2006-06-06 Tim Rice <tim@multitalents.net>.
2002 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2003 "ERROR" only shows up in "make check" output if there is an
2004 error.
2006 2006-06-06 Eric Blake <ebb9@byu.net>
2008 * tests/tools.at (automatically allowed tokens): Fix typo.
2010 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2012 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2014 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2015 typically overflows on x86 CPUs, even though the C standard
2016 requires otherwise.
2018 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2020 * configure.ac (AC_INIT): Bump to 2.59e.
2021 * NEWS: Update.
2023 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2025 Version 2.59d.
2027 * config/texinfo.tex: Sync from upstream.
2029 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2030 seen, invoke libtoolize with `--ltdl' argument.
2031 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2032 * NEWS: Update.
2033 Suggested by Eric Blake.
2035 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2037 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2038 reported by Ralf Wildenhues.
2039 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2041 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2043 * THANKS: Update.
2045 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2047 * doc/autoconf.texi: Modernize some of the references to Solaris.
2049 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2051 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2052 message issued by AC_REQUIRE.
2053 * tests/m4sugar.at: Check m4_require's error message.
2054 * tests/base.at: Check AC_REQUIRE's error message.
2055 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2056 to...
2057 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2058 AT_CHECK_M4.
2059 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2060 `expout' as the last parameter.
2061 * tests/tools.at: Adapt to the above change.
2063 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2065 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2066 information about race-free implementations of mkdir.
2068 2006-06-04 Eric Blake <ebb9@byu.net>
2070 * bin/autoreconf.in (help): Document M4 environment variable.
2071 * bin/autoconf.as (Usage): Likewise.
2072 * bin/autom4te.in (help): Likewise.
2073 * doc/autoconf.texi (autom4te Invocation): Likewise.
2075 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2077 * NEWS: GNU make now recommended for VPATH builds.
2078 Mention that some macros are now documented to be obsolescent.
2079 * doc/autoconf.texi:
2080 Prefer "current" to "modern" to describe
2081 currently-used (albeit perhaps old-fashioned) hosts.
2082 Mention which ancient features no longer need to be worried about.
2083 setgid -> set-group-ID
2084 setuid -> set-user-ID (these are the Posix terms)
2085 Fix some misuses of "only".
2086 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2087 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2088 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2089 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2090 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2091 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2092 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2093 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2094 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2095 Mention that these macros are obsolescent.
2096 (Installation Directory Variables): shall -> should
2097 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2098 Mention that it's now safe to use 3 and 4.
2099 (Limitations of Usual Tools): cp -r is now specified by Posix.
2100 Omit longwinded and obsolescent discussion of cp -f.
2101 Modernize discussion of expr, ls.
2102 (Limitations of Make): Modernize discussion of VPATH builds.
2103 Mention $? as a workaround in some cases.
2104 * doc/install.texi (Basic Installation):
2105 Mention "./configure; make; make install" first. Be more
2106 specific about why this file is generic. Remove unnecessary
2107 parens. Remove misleading "only". Remove obsolete advice
2108 about csh. Don't say "configure" takes awhile; say it
2109 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2110 and CC=c99 rather than CC=c89, as these are blessed by current
2111 Posix. Recommend GNU make if doing a VPATH build.
2113 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2115 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2116 examples involving shell prompts.
2118 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2119 and Paul Eggert <eggert@cs.ucla.edu>
2121 * doc/autoconf.texi (Here-Documents): Add details about the
2122 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2123 use "here-documents" instead of "here documents".
2125 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2127 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2129 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2131 * doc/autoconf.texi (File System Conventions): Warn about ":"
2132 anywhere in directory names.
2134 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2136 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2137 about quoting the case statement, just in case.
2138 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2139 was fixed in ksh93g; reported by Ralf Wildenhues.
2141 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2143 * doc/autoconf.texi (System Services): Do not document
2144 overriding EXEEXT via ac_cv_exeext=ext.
2145 (Particular Programs) <AC_PROG_MKDIR_P>:
2146 Document that ${MKDIR_P} understands --.
2147 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2148 comment.
2150 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2152 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2153 argument with leading hyphen. Problem reported by Paul Eggert.
2155 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2157 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2158 about quoting ac_try: quote all of it, if any of it seems suspicious.
2159 This means we don't have to worry about ${ or sed any more.
2160 Also, double-quote the case statement, to work around misuses via
2161 underquoting as reported by Ralf Wildenhues in
2162 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2163 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2164 undocumented and dangerous macro.
2165 Problem reported by Ralf Wildenhues in
2166 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2168 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2170 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2171 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2172 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2174 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2176 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2177 since evidently some packages rely on the old, broken behavior.
2178 Problem reported by Ralf Wildenhues in
2179 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2180 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2181 pre-2006-05-26 definitions, but leave in the comments that
2182 these macros are dangerous and should not be used.
2183 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2184 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2185 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2186 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2187 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2189 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2191 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2192 the use of 'tr', since this is our only use of 'tr'.
2194 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2195 and Paul Eggert <eggert@cs.ucla.edu>
2197 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2198 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2200 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2202 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2203 the output file in the `${datarootdir}' test.
2205 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2206 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2208 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2209 mention of `datarootdir' in the input file(s), but literal
2210 `${datarootdir}' in the output file, and we haven't warned yet,
2211 then warn as well: the user may have (erroneously) used
2212 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2213 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2214 * tests/torture.at (datarootdir workaround): Extend this test.
2215 * NEWS: Update.
2217 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2218 and Paul Eggert <eggert@cs.ucla.edu>
2220 * doc/autoconf.texi (autoheader Invocation): The first argument to
2221 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2222 alternatives and clear up the language a bit.
2224 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2226 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2227 ac_config_guess, ac_config_sub, ac_configure.
2228 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2229 Fix typo that prevented an unnecessary space from being removed.
2230 Problems reported by Ralf Wildenhues in:
2231 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2233 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2235 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2236 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2237 Don't use the term "thread-safe" to talk about mkdir race
2238 conditions, since the problem is more a process than a thread
2239 issue. Problem reported by Stepan Kasal in:
2240 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2241 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2242 the test for 'install' more closely. Look at MKDIR_P first.
2243 Look in the PATH, and at /opt/sfw/bin.
2244 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2245 Don't bother to try mkdir -p, since we already check mkdir --version;
2246 just look at the version number. (There's no easy way to check
2247 for race-free implementations.)
2248 * tests/tools.at (autoconf: subdirectories): Adjust to above
2249 changes, since MKDIR_P now might end in "/mkdir -p".
2251 * doc/autoconf.texi (autoheader Invocation): Mention that the
2252 first arg of AC_DEFINE_UNQUOTED must be a literal.
2253 Problem reported by Ben Pfaff in
2254 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2256 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2257 * doc/autoconf.texi (Special Chars in Variables): New section.
2258 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2259 (Installation Directory Variables): Quote $(datadir) better.
2260 (Limitations of Builtins): Describe some of eval's trickiness.
2262 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2263 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2264 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2265 in front of every arg, not just trailing args. Quote apostrophes.
2266 (_AC_EVAL_ECHO): New macro.
2267 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2268 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2269 removed.
2270 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2271 exposed by quoting of eval argument. Put the command on line line
2272 so it logs better.
2273 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2274 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2275 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2276 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2277 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2278 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2279 Use eval more safely.
2280 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2281 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2282 to be replaced.
2283 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2284 lines, exposed by quoting of eval argument.
2286 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2287 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2289 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2290 initialization of `ac_cv_exeext', do not override it if it was
2291 already set, unless it was set to `no', for compatibility with
2292 Autoconf-2.13, and comment this.
2293 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2294 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2295 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2296 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2297 Document that this test may be overridden by setting
2298 `ac_cv_exeext'.
2300 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2302 Revert these two patches:
2304 2006-04-06 Eric Blake <ebb9@byu.net>
2305 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2306 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2307 2006-04-01.
2309 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2310 Clean up _AC_COMPILER_EXEEXT* macros.
2311 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2312 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2313 ac_file to the name of the default output file and call
2314 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2315 initial `rm' of the candidate files...
2316 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2317 the same list in subsequent `rm' calls, and for the temporary
2318 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2319 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2320 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2321 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2322 no longer needed) by libtool. Make it a cache check.
2323 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2324 copied here by mistake.
2325 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2326 _AC_COMPILER_EXEEXT.
2327 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2328 _AC_COMPILER_OBJEXT directly.
2329 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2331 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2333 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2334 Fix description of how the buggy `sed' works.
2336 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2338 Sync from Automake:
2340 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2341 ENOLCK. Only mention `make -j' when applicable. Only raise
2342 fatal errors when `make -j' is involved. Improve error message.
2344 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2346 * doc/autoconf.texi (Here-Documents): We now know more about
2347 the variable expansion in here documents bug.
2348 Thanks to Tim Rice and Stepan Kasal.
2350 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2351 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2353 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2355 * tests/autotest.at (Multiline command from M4 expansion):
2356 No failure to be expected if the shell quotes newlines in
2357 commands in the `set -x' output. Report by Tim Rice.
2358 * THANKS: Update.
2360 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2362 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2363 expansion in the here-documents used by config.status, as that
2364 runs afoul of the Korn shell version M-12/28/93d bug described in
2365 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2366 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2367 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2369 2006-05-23 Jim Meyering <jim@meyering.net>
2371 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2372 Fix typo introduced with 2006-04-02 change. It reversed the sense
2373 of the test.
2375 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2377 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2378 ac_dB slightly, to save bytes in the script.
2379 Max out at 50 lines, rather than 96; this is more likely
2380 (though not guaranteed) to avoid obscure 'sed' failures.
2382 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2384 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2385 `tr -d -' as bad option argument. Work around this by deleting
2386 an unrelated character.
2387 Report by Tim Rice <tim@multitalents.net>.
2389 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2390 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2391 Stepan Kasal <kasal@ucw.cz>
2393 * doc/autoconf.texi (Particular Programs): Do not promise that
2394 we always prefer the GNU version of the program, and that we
2395 search according to PATH; both rules can have exceptions.
2396 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2397 AC_PROG_SED. Move descriptions of limitations
2398 to the Limitations of Usual Tools section.
2399 (Limitations of Usual Tools) <sed>: Mention script length
2400 limitations with Solaris /usr/ucb/sed.
2401 <grep>: Fix wording for empty alternative. Mention that -c and
2402 -l should not be combined, and that -E and -F should not be
2403 combined.
2405 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2406 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2408 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2409 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2411 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2413 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2414 AC_DEFINE is now passed to m4_pattern_allow.
2415 * NEWS: Mention that; likewise for AC_SUBST.
2416 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2417 the parameter to m4_pattern_allow.
2418 * tests/tools.at: Add a check for that.
2420 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2422 * lib/autoconf/status.m4: Fix typos.
2424 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2426 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2427 only the files that this macro generates.
2429 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2431 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2432 the HP-UX sed limitation of 99 commands, labels do not count.
2433 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2434 in the comment.
2435 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2437 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2439 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2440 Import the following fix from coreutils:
2442 2006-01-13 Jim Meyering <jim@meyering.net>
2444 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2445 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2446 not double-quote uses of that variable, to accommodate the rare
2447 case in which getmntent is available in none of the libraries
2448 checked. This happens at least on FreeBSD 5.0.
2450 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2452 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2453 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2454 some other programs unwisely rely on these undocumented vars.
2455 But put in warning comments about them.
2456 Problem reported by Ralf Wildenhues in
2457 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2458 * NEWS: Document that these variables are intended to go away.
2460 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2462 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2463 and set the language to C++ (analogous to the equivalent Fortran
2464 tests).
2466 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2467 * doc/autoconf.texi (C++ Compiler): Document it.
2468 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2469 * NEWS: Update.
2471 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2473 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2474 that caused config.status to generate 100-command sed scripts; the
2475 portable limit is 99.
2477 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2479 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2480 variable `ac_d' instead of `d' to avoid infringing namespace.
2481 Report by Ralf Menzel.
2483 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2485 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2486 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2487 * tests/tools.at (autoconf: subdirectories): New test, taken from
2488 the corresponding problem report by Ralf Wildenhues in:
2489 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2491 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2492 Quote some uses of shell variables if they might suffer unexpected
2493 globbing. This doesn't fix all instances of quoting problems that
2494 I found, just the easy ones that look safe.
2495 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2496 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2497 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2498 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2499 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2500 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2501 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2502 Likewise.
2503 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2504 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2506 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2508 * bin/autoreconf.in ($help): Reword according to the manual.
2509 Suggested by Olly Betts.
2511 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2512 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2514 * bin/autoreconf.in: Pass the directory argument to
2515 `require_configure_ac'. Fix comment.
2516 * tests/torture.at (Configuring subdirectories): Expose this.
2517 Reported by Olly Betts.
2519 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2521 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2522 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2523 Automake as follows:
2525 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2526 `$configure_in' instead of `configure.in', to preserve
2527 directory component.
2529 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2531 * config/config.guess, config/config.sub, config/texinfo.tex,
2532 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2534 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2536 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2537 test for C99 conformance; (bool) 0.5 is an integer constant
2538 expression, but (bool) -0.5 is not. Problem reported by Fedor
2539 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2541 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2543 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2544 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2545 Warn about obsolete install-sh files. Remove stray sentence
2546 fragment and fix cross reference.
2547 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2548 install -d; this undoes the 2006-05-10 change.
2549 (MKDIR_P): Mark with AN_MAKEVAR.
2550 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2551 that we don't require $INSTALL to be thread-safe. Move comments
2552 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2553 of AC_PROG_INSTALL. Output a message saying that we're checking
2554 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2555 MKDIR_P instead of AC_SUBST.
2556 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2557 Special magic for MKDIR_P, too.
2558 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2559 a dnl.
2560 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2562 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2564 Sync from Automake, as follows:
2566 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2567 * config/install-sh: Initialize IFS, so field splitting isn't
2568 turned off later.
2569 * config/mkinstalldirs: Likewise.
2570 * config/missing: Remove superfluous quotes. Replace all uses of
2571 `[' by `test', for consistency, and for..
2572 * config/missing (sed_minuso, sed_output): New variables.
2573 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2574 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2575 Fixes `missing' to detect `--output' for help2man. Fixes
2576 PR automake/483. Report by Dennis J. Linse.
2577 (autom4te): Document in `missing --help'.
2579 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2581 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2582 * config/install-sh: Don't use 'path' to talk about file names,
2583 as per GNU coding standards. Close a race condition reported by Ralf
2584 Wildenhues and Stepan Kasal. There is still a race condition
2585 on hosts that predate Posix 1003.1-1992, but we can't help this.
2586 Don't mishandle weird characters like space on pre-Posix hosts.
2587 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2588 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2589 AC_PROG_MKDIR_P from AS_MKDIR_P.
2590 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2591 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2592 earlier editions are not (including Automake 1.8.3).
2593 Do not suggest mkinstalldirs for thread-safety.
2594 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2595 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2596 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2597 presence of special characters and race conditions.
2598 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2599 in Autoconf's name space.
2601 2006-05-10 Bruno Haible <bruno@clisp.org>
2602 and Paul Eggert <eggert@cs.ucla.edu>
2604 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2605 from Automake with minor changes.
2606 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2608 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2610 * config/install-sh: Update to Automake CVS version, as follows:
2611 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2612 * lib/install-sh: Simplify the expr implementation of dirname.
2613 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2614 * lib/install-sh: Handle --, and diagnose unknown options.
2616 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2618 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2619 `./autom4te' to create `./testsuite', since the `all' target
2620 will ensure its presence, but `installcheck' should not create
2621 the uninstalled wrappers.
2623 * tests/torture.at (Unusual Automake input files): Skip if we
2624 detect automake < 1.8.
2626 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2628 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2629 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2630 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2631 * NEWS: Update.
2633 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2635 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2636 munge (multiple) white space and other oddities.
2637 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2638 single quotes in variable assignment.
2639 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2640 and similar failures by adding multiple spaces, tabs, and other
2641 special characters.
2642 Report and different test suggested by Francesco Romani
2643 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2645 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2646 single quotes, we only need to search for single quotes; this
2647 both simplifies the search pattern, and makes us less
2648 susceptible to `echo' variations for arguments not containing
2649 single quotes.
2650 (_AC_ARG_VAR_VALIDATE): Likewise.
2652 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2654 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2655 `$*' and IFS concatenation issue with traditional shells and
2656 bash-2.04. Report by Seanster@Seanster.com.
2658 2006-05-03 Bruno Haible <bruno@clisp.org>
2660 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2661 precisely which Mac OS X versions have the od problem.
2663 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2665 * doc/autoconf.texi: Use @option systematically.
2667 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2668 and Bruno Haible <bruno@clisp.org>
2670 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2671 about 'od'.
2672 (Integer Overflow): Mention the special case of integer division
2673 overflow.
2675 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2677 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2678 traditional shells like the Solaris one that do not use the
2679 first IFS character for assembling `$*'.
2680 Prompted by a related report from autoconf_bug@nro.ca.
2682 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2683 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2685 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2686 Mention more problems with the -e option.
2688 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2690 * NEWS: Typo.
2691 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2693 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2694 in URLs to improve DVI formatted output (requires texinfo 4.6).
2695 (System Services, Systemology, Shellology): Likewise.
2696 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2697 output.
2699 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2700 continuous text.
2701 (Runtime): Fix macro argument names to match description:
2702 `action-if-found' -> `action-if-true' and similarly.
2703 (Obsolete Macros): Likewise.
2704 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2705 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2706 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2708 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2710 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2712 * ChangeLog: Typo.
2713 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2714 DVI output.
2716 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2718 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2719 /bin/sh set unsorted output.
2720 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2721 * tests/local.at: Likewise.
2723 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2725 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2726 (Integer Overflow, Null Pointers, Buffer Overruns):
2727 (Floating Point Portability, Exiting Portably): New sections.
2728 (Writing Test Programs): Fix some langauge. Recommend exiting
2729 with status 1, not merely nonzero. Clarify exit declaration.
2730 (Run Time): Move C exit status stuff to new Exiting Portably section.
2731 (Systemology): Mention Posix and levenez. Update v7 reference.
2732 (Portable Shell): Mention the Posix shell.
2734 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2736 * bin/autoconf.as (me): Replace by as_me.
2738 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2740 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2741 since as_me isn't set yet.
2743 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2745 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2746 a few minor bugs in this area.
2748 * doc/autoconf.texi (Programming in M4sh): Comment out the
2749 documentation of AS_BASENAME, for now.
2750 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2751 (Limitations of Builtins) <basename>: Do not refer to
2752 AS_BASENAME.
2753 * bin/autoconf.as (me): Don't use AS_BASENAME.
2754 (dir): Remove the unused variable.
2755 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2756 AS_DETECT_REQUIRED. All uses changed.
2757 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2758 All uses changed.
2759 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2760 (AS_BASENAME): Use "basename --" to protect against leading "-".
2761 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2762 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2763 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2764 (_AS_DIRNAME_PREPARE): Likewise.

2766 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2767 (AS_DIRNAME): Use "dirname --".
2769 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2771 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2772 of "run time" and "run-time" changed to "runtime", for consistency.
2773 * lib/autoconf/fortran.m4: Likewise (in comment).
2774 * lib/autoconf/functions.m4: Likewise.
2775 * lib/autoconf/general.m4: Likewise.
2776 * lib/autoconf/headers.m4: Likewise.
2778 * doc/autoconf.texi (Run Time): Document the exit status situation
2779 with more accuracy and detail.
2781 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2783 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2784 Archive is not officially `GNU' any more. Update URL.
2785 (Defining Directories): Likewise
2786 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2788 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2790 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2791 newline from the `trap' code to finish `config.log'; the NetBSD
2792 /bin/sh resets the exit status after an empty command, as
2793 documented in doc/autoconf.texi.
2794 Reported by Dalibor Topic <robilad@kaffe.org>.
2796 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2798 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2799 Suggested by Bruno Haible.
2801 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2803 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2804 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2805 Instead, just list the shells that we know work.
2806 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2807 changed. Be more cautious about the _cv_ variable.
2808 * tests/tools.at (Syntax of the shell scripts): Check the
2809 _cv_ variable once, at first, to avoid an internal autoconf error
2810 when sh -n does not work.
2812 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2814 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2816 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2818 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2819 use ">&-" since we're only 99.999% sure that this is portable,
2820 and since the MinGW bug is fixed in a different way.
2821 * lib/autotest/general.m4 (AT_INIT): Likewise.
2823 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2825 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2826 before opening config.log, to avoid hitting a bug on MinGW.
2828 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2830 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2831 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2832 This works around a MinGW bug reported by Eric Paire.
2833 Make sure that all writes to the log file append to it,
2834 rather than possibly losing data.
2835 * lib/autotest/general.m4 (AT_INIT): Likewise.
2837 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2839 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2840 description.
2842 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2844 * NEWS: Update.
2846 * configure.ac (AC_INIT): Bump to 2.59d.
2848 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2850 Version 2.59c.
2852 * Makefile.maint (news-date-check): Do not require a leading `*'
2853 before the release date in NEWS.
2855 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2856 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2858 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2859 the instantiated file do not contain the string 'datarootdir'
2860 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2861 @mandir@, replace the reference '${datarootdir}' by the value.
2862 * tests/torture.at (datarootdir workaround): New test.
2863 * NEWS: Advertise this temporary fixup.
2864 Based on a patch by Bruno Haible, reported and analyzed by
2865 Paul Eggert and Noah Misch.
2867 2006-04-12 Eric Blake <ebb9@byu.net>
2869 * tests/autotest.at (Debugging a failed test): Fix comment.
2871 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2873 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2874 all the changes since 2006-04-07.
2876 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2878 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2879 succeeded, but `ln -s file dir' failed, take care to remove the
2880 leftover target before the next test, to prevent its spurious
2881 failure; also make sure `ln file dir' works before selecting it.
2882 Thanks to Keith Marshall for pointing this out.
2883 * THANKS: Update.
2885 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2886 assignments in `at_debug_args', so that we put them correctly
2887 in the `run' script.
2888 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2889 Reported by Eric Blake.
2891 2006-04-11 Eric Blake <ebb9@byu.net>
2893 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2894 top-level tests after micro-suite has been run. Used in...
2895 (Debugging a successful test, Debugging script and environment),
2896 (Debugging a failed test): ...these new tests. The first of these
2897 is fixed by...
2898 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2899 macro, split out from...
2900 (AT_INIT): ...here, so that using -d also generates a run script.
2901 Document that -d inhibits top-level logging.
2902 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2903 inhibits top-level logging; debug scripts are created.
2905 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2906 check.
2907 * tests/autotest.at (Empty test, Empty check): New test to check it.
2909 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2910 from gcc.
2912 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2914 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2915 the files if a problem appears. Make the empty *.at files
2916 read-only, too. Proposed by Ralf Wildenhues.
2918 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2920 * config/Makefile.am: Add comment to force updated Makefile.in.
2922 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2923 space only patch to this file, this patch causes the Makefile.in
2924 files that include freeze.mk to be updated, and thus have a
2925 newer time stamp again, which in turn makes a pristine CVS
2926 checkout have correct time stamps.
2928 * Makefile.maint (cvs-sv): New macro, to be used..
2929 (config.guess-url_prefix, config.sub-url_prefix)
2930 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2931 point to CVS text checkout of Gnulib files.
2932 (copyright-check): Bump current year.
2933 (announcement): Do not hard-wire `./announce-gen'.
2934 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2935 correctly.
2936 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2937 `chmod +x'.
2938 (wget_files): Update config.guess, config.sub, texinfo.tex by
2939 `wget-update', now that their URLs work again.
2941 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2943 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2944 Problem noted by Paul D. Smith.
2946 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2948 * doc/autoconf.texi: Remove unused words from word list.
2949 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2950 .x-sc_trailing_space: New files.
2952 * doc/standards.texi: Sync from gnulib.
2954 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2955 `LIBOBJDIR' as experimental.
2957 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2958 with a target directory; it's internally implemented as `cp'
2959 anyway, but since Autoconf advertises the possibility to use
2960 a target directory when LN_S is `ln -s', we need to find out.
2961 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2962 analyzed by Keith Marshall <keith.marshall@total.com>.
2964 * THANKS: Update.
2966 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2968 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2969 confdefs.h as-is. In general, if it has backslash-newline or the
2970 like, then it doesn't work either to sort or to remove empty
2971 lines.
2973 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2975 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2977 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2979 * lib/autom4te.in (Automake-preselections): Preselect
2980 _AM_SUBST_NOTMAKE.
2982 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2984 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2985 apostrophe within a single-quoted string, as this is the usual
2986 tradition and is easier to read than '"'"'. Don't rely on the
2987 shell treating "$/" like '$/'. Use a more-consistent indenting
2988 style for the trap.
2990 2006-04-09 Eric Blake <ebb9@byu.net>
2992 * tests/autotest.at (Backquote command substitution),
2993 (Multiline backquote command substitution): Remove mistaken
2994 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2995 applied...
2996 (Parenthetical command substitution, Multiline parenthetical
2997 command substitution): here.
2999 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3001 Import macros from gnulib (often changing their name).

3015 (Pointers): Add Gnulib URL.
3016 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3017 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3018 Gnulib section.
3019 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3020 suggest a #define rather than a typedef for _Bool, and mention
3021 Gnulib rather than trying to substitute stdbool code.
3022 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3023 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3024 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3025 AC_STRUCT_DIRENT_D_TYPE.
3026 (Particular Types): Mention stdint.h and inttypes.h as standard
3027 headers too.
3028 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3029 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3030 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3031 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3032 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3033 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3034 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3035 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3036 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3037 (Coding Style). Don't mention m4_expand_once.
3038 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3039 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3040 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3041 (AC_CHECK_FUNCS): Use it.
3042 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

3045 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
3046 (AC_HEADER_ASSERT): New macro.
3047 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3048 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3049 Catch a bug in an HP-UX C compiler.
3050 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3051 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

3055 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3056 New macros.
3058 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3059 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3061 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3063 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3064 of the warning introduced by the 2001-08-28 change.
3066 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3067 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3069 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3070 variables shall be overriden by the cache.
3071 * tests/torture.at (AC_ARG_VAR): Test also with a first value
3072 that contains braces.
3074 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3076 Revert the patch from 2006-04-01 and only improve
3077 _AS_DETECT_BETTER_SHELL:
3079 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3080 skip nonexistent directories.
3081 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3082 only shell candidates which exist.
3083 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3084 * lib/autotest/general.m4 (AT_INIT): No need to give three
3085 parameters to _AS_PATH_WALK.
3087 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3088 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3090 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3091 distinguish m4sugar macros.
3092 * tests/tools.at (autoupdating with aclocal and m4_include):
3093 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3094 test case by Noah Misch <noah@cs.caltech.edu>.
3096 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3098 Revert my change from 2006-03-17, in other words:
3099 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3100 and DUALCASE=1.
3101 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3102 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3103 it is set.
3105 2006-04-07 Eric Blake <ebb9@byu.net>
3107 * doc/autoconf.texi (Programming in M4sh): Document that
3108 AS_MKDIR_P exits the script on failure.
3109 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3111 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3113 * config/elisp-comp, config/install-sh, config/mdate-sh,
3114 config/missing, config/mkinstalldirs: Sync from Automake.
3116 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3117 from Automake.
3119 * doc/make-stds.texi: Sync from gnulib.
3121 2006-04-06 Eric Blake <ebb9@byu.net>
3123 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3124 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3125 2006-04-01.
3127 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3128 Eric Blake <ebb9@byu.net>,
3129 Paul Eggert <eggert@cs.ucla.edu>,
3130 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3132 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3133 whether `set' quotes correctly: redirect stderr of the tested
3134 `set', and use a subshell, for Ultrix; use `sed' instead of
3135 `grep' for zsh `set' which may write binary output; match only
3136 at the beginning of a line, to avoid false positives.
3137 In order to avoid false positives by unrelated variables with
3138 multiline content, put the dump algorithm in a subshell and
3139 unset all variables containing newlines (except some which are
3140 special to the shell). Warn about cache variables that are
3141 unset.
3143 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3145 * config/config.guess, config/config.sub, config/texinfo.tex:
3146 Sync from upstream.
3148 * tests/mktests.sh: Reword comments.
3150 * tests/mktests.sh: Only skip internal macros starting with
3151 `_AC_' or `__AC_'. Noted by Stepan Kasal.
3152 Update exclusion lists for the test suite to this end:
3153 (AC_ARG_VAR): Do test this now.
3154 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3155 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3156 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3157 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3159 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3160 shell issue with double-quoted command substitutions of native
3161 commands.
3162 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith

3344 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3345 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3346 ac_file to the name of the default output file and call
3347 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3348 initial `rm' of the candidate files...
3349 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3350 the same list in subsequent `rm' calls, and for the temporary
3351 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3352 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3353 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3354 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3355 no longer needed) by libtool. Make it a cache check.
3356 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3357 copied here by mistake.
3358 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3359 _AC_COMPILER_EXEEXT.

3396 subordinate tools.
3397 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3398 * doc/autoconf.texi (autoreconf Invocation): Document it.
3400 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

3434 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3435 switch all of them on and of when necessary. Fixes the bug when

3487 checked for existence, so we don't barf over a nonexisting
3488 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3490 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4080 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
4081 ac_pt_* variables.
4083 2005-11-01 Stepan Kasal <kasal@ucw.cz>
4085 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
4086 filesystems.
4088 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4090 * NEWS: Move AH_HEADER mention to right place.
4092 2005-10-27 Stepan Kasal <kasal@ucw.cz>
4094 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
4095 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4097 2005-10-25 Stepan Kasal <kasal@ucw.cz>
4099 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
4100 conftst2.$ac_objext.
4101 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4103 2005-10-24 Stepan Kasal <kasal@ucw.cz>
4105 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4106 conftest.o, to see whether the compiler really obeys; rm the object
4107 file before and after the test and register it with ac_clean_files.
4108 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4110 2005-10-21 Stepan Kasal <kasal@ucw.cz>
4112 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
4113 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
4114 code so that the most common case requires less forks.
4116 2005-10-20 Stepan Kasal <kasal@ucw.cz>
4118 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
4119 not portable; thanks to Paul Eggert and Alexandre.
4121 * NEWS: Fix an old typo.
4123 2005-10-20 Jim Meyering <jim@meyering.net>
4125 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
4126 the latter'', in two places.
4128 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4130 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4131 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4132 the inner workings of AC_LANG_FUNC_LINK_TRY.
4133 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4134 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4135 by the function rather than ignoring it.
4136 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4137 comparing its address. Intel's interprocedural optimization was
4138 outsmarting the old heuristic. Problem reported by
4139 Mikulas Patocka.
4141 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4143 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
4145 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
4147 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

4150 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4152 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4153 before removing it (chmod -R u+rwx); there are three instances of this.
4155 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4156 Stepan Kasal <kasal@ucw.cz>
4158 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4159 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4160 make its content writable before removing it. Remove an errorneous
4161 comment from the end, where the logs of the failed tests are copied
4162 to the main log file.
4164 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4166 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4167 in case the computer is too quick. Double quote the configure.ac
4168 snippets.
4170 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4171 problems if the testsuite were running too fast.
4173 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4175 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4176 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4177 (which belong to Xt, not X itself). See Debian bug 327655.
4178 * NEWS: Mention this.
4180 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4182 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4184 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4186 * config/move-if-change: Don't output "$2 is unchanged";
4187 suggested by Ben Elliston. Handle weird characters correctly.
4189 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4191 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4192 calls, so that the final expansion of this macro is shorter.
4193 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4194 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4195 the cleanup there. Use AS_VAR_* macros, to be more general.
4196 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4198 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4200 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4202 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4204 * doc/autoconf.texi (Configuration Headers): Add an index entry
4205 for AH_HEADER.
4207 2005-08-26 Pavel Roskin <proski@gnu.org>
4209 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4210 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4211 running xmkmf.
4213 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4215 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4216 The previous patch didn't work, so try a better one.
4218 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4220 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4221 in the example. Reported by Bruno Haible.
4222 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4223 "if $undefined_var;" succeeds with my shell.
4225 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4226 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4227 but change the m4_divert_text to m4_divert_once.
4229 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4231 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4232 Work around bug in Solaris /usr/xpg4/bin/awk.
4233 The bug is present in at least Solaris 8 through 10.
4235 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4237 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4238 some evil values and relying on the fact that $* concatenates the
4239 parameters by the first character from IFS.
4241 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4242 Stepan Kasal <kasal@ucw.cz>
4244 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4245 first header appears, define AH_HEADER.
4246 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4247 Update limitations about when to call AC_CONFIG_HEADERS.
4248 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4249 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4250 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4251 ``Configuration Actions''; fix their index entries.
4253 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4254 options correctly. Process N-M as M-N if M is smaller than N.
4255 Process ranges correctly so that N-N will run only N.
4256 Sort and uniquify the tests that will be run. If there is more
4257 than one test, reinsert the banners for the tests.
4258 * tests/autotest.at (Keywords): Unmark XFAIL.
4260 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4262 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4263 before passing the macro name to AH_TEMPLATE.
4265 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4266 now opens log after option processing; in particular, --version
4267 and --help do not touch config.log.
4269 * Makefile.maint: Revert the change from 2005-08-12.
4271 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4273 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4274 common code to...

4277 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4279 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4280 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4281 Language cleanup.
4283 * doc/autoconf.texi (Defining Symbols, Changed Results):
4284 Prepend to LIBS, not append, in examples.
4286 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4288 When building in place, set srcdir="."; suggested by Tim Van Holder.
4290 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4291 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4292 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4293 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4294 does not mean "no --srcdir option".
4296 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 * tests/autoscan.at (autoscan): New file.
4299 * tests/suite.at: Use it.
4300 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4301 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4303 * tests/autotest.at (Keywords): Test keywords combinations.
4305 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4307 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4308 add "2>&1"; gzip 1.2.4 prints help on stderr.
4310 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4312 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4313 was pushdef'ed twice while popped only once. Push it only once.
4314 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4316 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4318 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4323 * Makefile.maint: Update from Bison.
4325 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4326 "<tab>" in comment, so that the point is understandable.
4328 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4330 Rewrite substantial part of lib/autoconf/status.m4.
4331 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4332 and CONFIG_COMMANDS are not processed in four separate loops.
4333 Instead, there is one main loop. This alows that the common code
4334 is expanded only once, thus config.status (and configure) is smaller.
4336 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4337 the AC_LIST_FILES and cousins macros are no longer used.
4339 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4340 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4341 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4342 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4343 contain the initialization, nor the for loop, nor the associated
4344 commands; all these go to ...
4345 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4346 _AC_OUTPUT_CONFIG_STATUS.
4347 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4348 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4349 (_AC_OUTPUT_FILE): The creation of the sed script ...
4350 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4351 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4352 _AC_OUTPUT_MAIN_LOOP.
4353 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4354 _AC_CONFIG_COMMANDS): Use ...
4355 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4356 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4357 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4358 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4359 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4360 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4361 ... new macros.
4362 (_AC_CONFIG_UNIQUE): Update.
4363 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4364 Replaced by this ...
4365 (_AC_LIST_TAGS): ... new common macro.
4366 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4367 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4368 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4369 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4370 this didn't belong to the `config commands' section.
4371 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4372 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4373 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4374 to the `config commands' section either.
4375 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4376 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4378 ... and many changes to the comments nearby.
4380 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4381 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4382 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4383 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4384 (#define header templates): The comment at the top of the generated
4385 header now includes the name(s) of the source file(s).
4387 Several unrelated small changes:
4389 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4390 parameter to AC_DIAGNOSE.
4391 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4392 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4393 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4394 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4395 with AU::AC_OUTPUT.
4396 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4397 in AC_OUTPUT doesn't double-quote it either.
4398 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4399 parameters.
4401 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4403 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4404 versions of Portland Group compiler produce single- and double-quoted
4405 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4406 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4408 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4410 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4411 This is a corrected version of yesterday's patch.
4413 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4415 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4416 path, too; insert a "===" to emphasize the line.
4418 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4419 ac_cv_build_alias to ac_build_alias.
4420 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4422 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4423 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4424 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4425 (AC_ARG_VAR): ... here.
4426 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4427 target_alias.
4429 Keep a list of all precious variables and process them with one simple
4430 for loop, instead of expanding all commands, or, OTOH, complicated
4431 processing of output of "set".
4432 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4433 variable names in new macro...
4434 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4435 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4436 a loop to assign all ac_env_* and ac_cv_env_* variables.
4437 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4438 to INIT_PREPARE.
4439 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4440 its value to shell variable ac_precious_vars and call
4441 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4442 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4443 _AC_ARG_VAR_VALIDATE.
4445 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4446 and the AC_SUBSTs ...
4447 (AC_INIT): ... here.
4449 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4450 the ac_subst_files section in config.log.
4452 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4454 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4458 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
4459 * tests/c.at (C keywords): Test AC_C_TYPEOF.
4461 Fix problems reported by Nicolas Joly.
4462 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4463 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4464 They are generated by the Tru64 v5.1B shell.
4466 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4468 Fix my changes from 2005-07-01; reported by Noah Misch.
4469 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4470 description, the macro now accepts only a single tag.
4471 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4473 Fix cases when the varsions of Autoconf and Autotest don't match.
4474 Reported by Noah Misch.
4475 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4476 at_top_builddir, for compatibility with older autotest.
4477 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4478 is not set, use at_top_builddir, for compatibility with older
4479 versions of autoconf.
4481 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4483 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4484 Problem reported by Patrick Welche.
4486 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4488 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4489 sed substitution command, so that we allow | in program prefixes
4490 and program suffixes. (& is a problem anyway; we're not fixing
4491 that here.)
4492 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4493 configure_input, top_builddir, srcdir, etc.
4494 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4495 PATH_SEPARATOR in AUTOTEST_PATH.
4497 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4499 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4500 for loop over config.site files using `set', to allow
4501 directory names containing IFS characters.
4503 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4505 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4506 directories with weird names. Apparently some people like living
4507 on the edge. However, improve the test that "pwd" actually does
4508 report a name for the working directory.
4509 * NEWS: Remove the claim that we test for funny chars in dir names.
4511 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4513 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
4514 replaced ...
4515 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.

4520 2005-06-30 Stepan Kasal <kasal@ucw.cz>
4522 * doc/autoconf.texi (Configuration Headers): Change the explanation
4523 about #include <config.h>.
4524 (Generic Functions): Mention the Gnulib project.
4525 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4527 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4528 document to output the default config_* lists to config.status.
4529 Don't recognize option --file, if the functionality is not there.
4530 Likewise for --header; moreover, recognize --he and --h as shortcuts
4531 for --help in that case.
4533 * lib/autoconf/status.m4: Fix the order of the "sections", so that it

4556 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4557 (AC_SUBST): Call it.
4558 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4559 the directory specific variables; but don't call it for configure_input.
4561 2005-06-28 Derek Price <derek@ximbiot.com>
4563 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4564 addition.
4566 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4568 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4569 directory have inherent problems with special characters like spaces,
4570 due to limitations in Make syntax. Problem reported by Alexandre
4571 Duret-Lutz.
4572 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4573 Also, fix Tru64 porting problem with shell patterns,

4587 variable into diagnostic. Make the diagnostic an error, not a warning,
4588 because we really don't support spaces and suchlike in dir names.
4589 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4590 Don't worry about backslashes in srcdir; it can't happen now.
4591 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4592 Simplify ac_optarg handling.

4617 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4618 b, t, r, w commands require single space, while : cannot have any.
4619 (Special Shell Variables): Fix sed code this in the example.
4620 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4621 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4623 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4624 expand to the empty list. Don't use two pairs of m4_changequote,
4625 it's not necessary.
4627 2005-06-20 Derek Price <derek@ximbiot.com>
4629 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4631 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4633 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4634 * doc/autoconf.texi:
4635 Don't mention Solaris versions so much, if a
4636 problem is common to all extant versions of Solaris. Say "SunOS
4637 4" instead of "SunOS" for SunOS 4.
4638 (awk): Mention more of the limitations of traditional Awk.
4639 (cat): Don't talk about cat -v.
4641 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4643 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4644 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4645 but the implementation is entirely different and is designed
4646 to be compatible with glibc strverscmp.
4647 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4649 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4650 on Mac OS X 10.4 reported by Peter O'Gorman in:

4652 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4653 Use shell builtins rather than 'expr', to work around expr bug.
4655 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4657 * doc/autoconf.texi: "filesystem" -> "file system".
4658 "behaviour" -> "behavior".

4660 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4661 as per POSIX.
4662 * lib/m4sugar/m4sh.m4: Likewise.
4663 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4664 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4666 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4667 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4668 to update the man page. That way, we don't have to check in new
4669 man pages every month.
4671 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4672 quotes and backslashes. Patch from Derek Price.

4677 AS_TR_SH.
4679 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4681 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4682 -u, since it outputs chatter if the input files are the same.
4683 Problem reported by Ralf Menzel.
4685 2005-06-08 Derek Price <derek@ximbiot.com>
4687 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4688 renaming them since they are about to be redefined anyhow.
4690 2005-06-08 Derek Price <derek@ximbiot.com>
4692 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4693 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4694 Move m4_undefine to alphabetical order.
4696 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4698 * README: Recommend GNU M4 1.4.3 or later.
4699 * doc/autoconf.texi (Introduction): Likewise.
4700 Reword to avoid some formatting glitches.
4701 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4702 Clarify explanation of HP compiler bug.
4703 Redo example output tp match current CVS snapshot.
4704 Use @example.org in email addresses when the examples
4705 might get inadvertently cut-and-pasted into user code.
4706 Remove example of autom4te usage that doesn't seem to work now.
4707 Use modern AC_INIT (except when the example is meant to be
4708 shown with Autoconf 2.13).
4709 Update ksh info for Solaris 9 and later.
4710 KB -> kB.
4711 Modernize description of Automake versions a bit.
4712 Don't claim a future version of Autoconf is near.

4715 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4717 * doc/autoconf.texi: Add [] to examples, so that the manual
4718 follows its own advice about quoting better.
4719 Reword to avoid some formatting glitches.
4720 * doc/installt.exi: Reword to avoid some formatting glitches.
4722 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4723 Tru64 ksh pattern matching bug. Reported against Libtool by
4724 Albert Chin <libtool@mlists.thewrittenword.com> and
4725 Nicolas Joly <njoly@pasteur.fr>.
4727 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4729 m4_cdr of one-member list was [[]] (one-member list containing an
4730 empty string) instead of [] (an empty list. Callers were skewed to
4731 match this misbehaviour. As a consequence of this:
4732 - m4_foreach([x], [], [foo]) expanded to `foo', while
4733 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4734 This bug has been fixed:
4736 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4737 expand to an empty string; print error msg if called without
4738 an argument list.
4739 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4740 misbehaviour; handle [] and [[]] correctly.
4742 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4744 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4746 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4748 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4750 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4751 swallow records with more than 99 fields.
4752 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4753 parse the long line.
4755 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4757 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4758 swallow literals longer than 399. Reported by Ralf Wildenhues.
4759 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4760 to workaround this limitation.
4762 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4764 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4765 to gfortran, and make these the first two compiler names
4766 checked (following the general autoconf preference for gcc).
4768 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4770 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4771 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4772 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4774 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4776 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4777 expression of unbounded size when processing the --list
4778 option. This runs afoul of a limit of 399 bytes per regular
4779 expression on AIX. Problem reported by Ralf Wildenhues.
4781 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4783 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4784 * doc/autoconf.texi (Particular Headers): Reword example
4785 for multiline stdbool replacement.
4786 (Setting Output Variables): Reword text a bit. Don't
4787 give all the details about |#_!!_#|.
4788 Reword description of line replacement.
4790 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4792 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4793 now contain newlines, and substituted files must be referenced on
4794 a line alone; the sed scripts to substitute them are now very
4795 different.
4796 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4797 commands can be put in a sed script portably.
4798 * doc/autoconf.texi (Setting Output Variables): Document above
4799 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4800 use of multiline substitution.

4810 * tests/local.at: Don't attempt to check for negated character
4811 classes in shell scripts. The test was too brittle.
4813 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4815 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4816 * doc/autoconf.texi (Limitations of Builtins): Document this
4817 limitation.
4819 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4821 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4822 common code; used in many places in the tree.

4824 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4826 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4828 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4829 messages when ac_unique_file is not found.
4830 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4831 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4832 commands, for consistency with AC_MSG_ERROR and such.
4834 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4836 * bin/Makefile.am: Merge the two rules for creating scripts.

4844 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4846 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4847 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4848 (ac_top_builddir): ... this ...
4849 (ac_top_build_prefix): ... to this; the old name is also kept, for
4850 backward compatibility.
4851 (ac_top_builddir_sub): New variable, without the trailing slash,
4852 always nonempty.
4853 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4854 * doc/autoconf.texi (Configuration Actions): Rename
4855 ac_top_builddir to ac_top_build_prefix.
4856 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4857 at_top_builddir to at_top_build_prefix.

4865 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4867 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4868 argument to m4_foreach. I guess it was necessary in the past,
4869 but I think it's a no-op now.
4871 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4873 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4874 ``cat <<_ACEOF'' commands to one.
4875 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4876 * lib/autoconf/status.m4: On various places, use expr instead of
4877 ``echo|sed.''
4878 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4879 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4880 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4881 a range.
4882 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4883 the wrong patterns between ``case'' and ``esac.'' The previous
4884 code had false positives.
4886 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4888 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4889 as on 2005-05-02.
4890 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

4952 * doc/autoconf.texi (Autoconf Language): Be more precise about
4953 quoting rules. Problems noted by Stepan Kasal.
4954 Also, throughout this document, be more careful about white space.
4955 "blank", "white space", and "space" all have different meanings
4956 and we should be careful to say what we mean.
4958 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4960 Fix C++ related problems reported by Werner Lemberg.
4961 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

4981 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4982 outputs 0 on GNU/Linux these days.
4984 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4986 * doc/autoconf.texi (Autoconf Language): Add more description
4987 about quoting heuristics.
4988 (Limitations of Builtins): Describe "set -" problems.
4990 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4992 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4993 not newline.
4995 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4996 by AC_DEFINE; it was a mistake.
4997 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4999 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5001 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5003 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5005 * doc/autoconf.texi (External Software): Quadrigraphs are not
5006 processed correctly in AS_HELP_STRING; avoid this in the examples.
5007 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5008 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5009 comment and reduce m4_default([foo], []) to [foo].
5010 (m4_strip): Update the explanation.
5012 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5014 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5015 Remove core.conftest.* too; it's generated by Tru64 5.1.
5016 Problem reported by Jennis Pruett.
5017 * lib/autoconf/functions.m4
5018 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5019 Don't bother to remove core files; AC_RUN_IFELSE should do that
5020 for you.
5022 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5024 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

5064 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5066 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5067 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5068 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5069 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5070 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5072 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5074 * NEWS: The configure command now warns you if you attempt to use
5075 a directory whose name contains a special character like space,
5076 newline, or "\".
5077 * doc/autoconf.texi (Installation Directory Variables): Allow
5078 "," in file names. Do not use \@; it's not a portable regexp.
5079 * bin/Makefile.am (edit): Likewise.
5080 * lib/Makefile.am (edit): Likewise.
5081 * tests/Makefile.am (edit): Likewise.

5089 (AC_INIT): Use it.
5090 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5091 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5092 ac_pwd, and quote srcdir.
5093 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5095 * doc/autoconf.texi: Fix some systematic formatting problems.
5096 ".)" needs a following @: if not at the end of a sentence, and
5097 similarly for "!)". "etc." should be preceded by a comma.
5098 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5100 2005-03-22 Bruno Haible <bruno@clisp.org>
5102 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5103 argument is often called 'build-aux'.
5105 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5107 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5108 macro AC_TRY_LINK is obsolete.
5109 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5110 `AC_CONFIG_FILES'.
5112 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5114 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5115 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5116 from a Common Lisp's `cl'.
5117 (AC_PROG_CXX): Behave according to the documentation: don't
5118 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5119 make the variable CCC precious; use `cl.exe', not `cl'.
5121 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5122 Alexandre Duret-Lutz <adl@gnu.org>
5124 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5125 /dev/null, as "configure" shouldn't read stdin, and this insulates
5126 us from problems (e.g., when testing for "cl"). Also, do this
5127 redirection before invoking "hostname" or "uname", and keep the
5128 original input stream available via...
5129 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5130 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5131 bother with "</dev/null" since it's now done at the top of
5132 'configure'.
5133 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5134 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

5140 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5142 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5143 newline if neither \c nor -n work, as that would output two
5144 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5146 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5148 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5149 This causes that any required macros inside will get before the if.
5150 * doc/autoconf.texi (autom4te.cache): A typo.
5152 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5154 Undo previous change, except keep the change to
5155 lib/autoconf/programs.m4 that replaced grep with shell
5156 pattern-matching. This is because net-snmp configure reads stdin.
5157 Reported by Noah Misch.
5159 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5161 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5162 from /dev/null, as "configure" shouldn't read stdin, and this
5163 insulates us from problems (e.g., when testing for "cl").
5164 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5165 before invoking "hostname" or "uname".
5166 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5167 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5168 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5169 "</dev/null" since it's now done at the top of 'configure'.
5170 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5171 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5172 Also, replace grep with shell pattern-matching, to save a process.
5174 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5176 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5177 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5178 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5179 compiler.
5181 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5183 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5184 grep -q isn't portable. Improve grep -s explanation.
5185 Problem reported by Dan Manthey.
5187 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5189 * doc/autoconf.texi (Special Shell Variables): Clarify
5190 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5192 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5194 * doc/autoconf.texi: Use @acronym for DJGPP.
5195 Fix some @code's that should have been @env's, and vice versa.
5196 Sort environment variable names.
5197 Mention that shells no longer inherit IFS.
5198 Don't recommend PATH_SEPARATOR=';' so strongly.
5199 Mention that $RANDOM might expand to the empty string.
5200 "symlink" and "soft link" -> "symbolic link".
5201 Improve mktemp description (reported by Bruno Haible).
5203 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5205 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5206 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5207 Likewise.
5208 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5209 Likewise.
5211 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5213 * NEWS: Mention AT_COPYRIGHT.
5215 * tests/local.at (AT_CMP): Use diff directly on input files rather
5216 than copying them.
5218 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5219 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5221 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5222 and Paul Eggert <eggert@cs.ucla.edu>
5224 * tests/autotest.at (Empty test suite): New test.

5231 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5232 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5233 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5234 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5235 (Standard regular expressions): New test.
5236 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5237 excess test name quoting.
5238 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5239 CPPFLAGS to `configure' instead of setting it in `configure'.
5241 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5242 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5243 on some platforms.
5245 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5246 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

5254 * tests/c.at (Extensions): Do not exit early.

5274 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5276 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5277 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5279 Try not to generated lines of unlimited length, as POSIX places a
5280 2047-byte limit on line length of portable text files.
5281 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5282 Use newline as a separator, not space.

5285 space.

5291 are restored after function return.
5293 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5295 * doc/autoconf.texi (Special Shell Variables): Mention _,
5296 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5297 if they contain a lower-case letter. The DUALCASE problem was
5298 reported by Ralf Wildenhues.
5300 * bin/autoconf.as: Don't exit with status 0 after write failure
5301 with --help or --version.
5302 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

5313 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5315 * man/Makefile.am (.x.1): Go back to the simple solution, but take

5317 Modified from a suggestion by Stepan Kasal.
5319 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

5326 * doc/install.texi (Defining Variables): Likewise.
5327 Based on a proposed patch by Ralf Wildenhues.
5329 * man/Makefile.am (.x.1): Make sure the required generated files
5330 are up to date. Problem and original solution proposed by Stepan Kasal.
5331 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5332 implicit-man-prerequisites): New rules, used by the above.

5338 2005-01-29 Stepan Kasal <kasal@ucw.cz>
5340 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5341 Update the long comment explaining it.
5343 m4_require no longer writes an ``is required by'' line to the
5344 execution stack. It contains only one bit of non-redundant
5345 information: that the macro was required, not called. And even
5346 this bit is useless in most situations: have you ever met a macro
5347 which both calls and requires the same macro?
5349 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5350 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5351 macro.
5352 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5353 (m4_expansion_stack_pop): Remove the misplaced comment.
5354 (m4_require): Don't put the ``is required by'' line to the
5355 execution stack; slightly improve the out-of-a-defun error message.
5356 (_m4_divert_grow): New macro, counter for the temporary diversions.
5357 (_m4_require_call): Use it.
5358 * tests/m4sugar.at (m4_require): Expect output without the
5359 ``is required by'' messages.
5361 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5363 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5364 rather than x for expr.
5366 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5367 this is safe.
5368 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

5380 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
5381 from masters, so that FileUtils.pm's update_file provide --force
5382 support.
5383 * bin/autoheader.in: Pass $force to update_file so that
5384 config.h.in is always recreated when --force.
5386 2005-01-24 Stepan Kasal <kasal@ucw.cz>
5388 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5390 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5392 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5393 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5395 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5397 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5398 Warn about newline stripping in `` and $(). Update Solaris
5399 version to 9.
5400 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5401 X insulates us from future changes to Posix.
5402 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5403 stripping.
5405 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5423 ulongval to be static, to avoid unwanted GCC warning. Problem
5424 reported by Michael Jennings via Daniel Reed; see
5425 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.

5769 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5770 "char c = '\200';" rather than "char c = 0x80;" as the

5888 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

5890 (trivial change). Problem and patch reported by Andrew Church in:
5891 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5893 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5895 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5896 three args in examples. Problem reported by Frederik Fouvry in:
5897 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5898 Also, fix some minor spacing and punctuation bugs.
5900 2004-09-02 Akim Demaille <akim@epita.fr>
5902 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5903 "case" to restore ordering.
5904 Reported by Stepan Kasal.
5906 2004-08-26 Akim Demaille <akim@epita.fr>

5920 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5921 texinfo.tex for now (done by hand now).
5922 * Makefile.maint (wget_files, cvs_files):
5923 Remove ansi2knr.c; nobody uses it.
5924 (ansi2knr.c-url_prefix): Remove.
5925 (cvs-update): Fix test for failure. I don't know why it ever
5926 worked...
5928 * doc/autoconf.texi: Update URLs, some of which went stale.
5929 Use @uref rather than @href.
5931 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5932 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5934 * config/config.guess, config/config.sub, config/elisp-comp,
5935 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5936 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5938 * NEWS, TODO, configure.ac, bin/autoscan.in,
5939 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5940 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5944 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5945 tests/tools.at, tests/torture.at:
5946 Use "file name" rather than "filename" or "path",
5947 to be consistent with the terminology of the GNU coding standards.
5949 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5951 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5952 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5953 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5954 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5956 More fixes to support spaces in the name of the build directory.
5957 This isn't a complete fix but it's an improvement.
5959 * bin/autoconf.as (autom4te_options): New var.
5960 Use it instead of appending to AUTOM4TE, so that we can allow
5961 spaces in the build directory's absolute name.
5962 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5963 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5964 AT_CHECK_NOESCAPE): Likewise.
5965 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5966 main program): Likewise.
5968 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5970 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5971 From Ralf Corsepius in:
5972 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5974 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5976 * doc/autoconf.texi (Function Portability): Document isinf and
5977 and isnan. From a suggestion by Kevin Ryde.
5979 * lib/Autom4te/General.pm (END): Return correct exit status even
5980 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5982 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5984 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5985 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5986 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5988 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5990 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5991 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5992 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5993 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5994 * lib/autom4te.in (Automake-preselections): Preselect
5995 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5997 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5999 * lib/autom4te.in (Automake-preselections): Preselect
6000 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6001 trace them.
6003 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6005 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6006 Tru64.
6007 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6008 Document problem with "`""`" in pdksh POSIX mode.
6010 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6012 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6013 with pdksh, too. Problem reported by Patrick Welche via
6014 Gary V. Vaughan.
6015 * doc/autoconf.texi (Shellology): Note that set -o posix is
6016 useful for pkdsh, too.
6018 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6020 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6021 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6022 Don't fail if ENV or BASH_ENV is readonly.
6023 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6024 etc. are read only. Problem reported by Ludovic Courtes.
6026 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6028 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6029 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6030 (trivial change)
6032 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6034 * doc/autoconf.texi (File System Conventions): Warn about
6035 names like "aux". Problem reported by Eric Blake.
6037 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6038 by zero instead of array size, so that we can use any arithmetic
6039 constant expression (instead of requiring an integer constant
6040 expression). This allows us to test expressions like DBL_MAX <
6041 LDBL_MAX, which didn't conform to the C standard using the old
6042 method.
6043 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6044 now that we can do floating-point tests at compile time.
6046 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6048 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6049 and LDBL_EPSILON, as the resulting expression isn't an
6050 integer constant expression and violates the C standard.
6051 Problem reported by Nelson H. F. Beebe. Also, check
6052 for "L" suffix, and check that long double doesn't have
6053 worse range or precision than double, that mixed-mode
6054 arithmetic doesn't generate a diagnostic, that double
6055 constants fit in long double.
6057 2004-06-03 Kevin Ryde <user42@zip.com.au>
6059 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6060 malloc(0) and realloc(NULL,size).
6062 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6063 Bob Proulx.
6065 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6067 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6068 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6069 by Jim Meyering.
6071 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6073 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6074 can be rewritten using if-then-else. Suggested by Bruno Haible.
6076 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6078 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6079 Problem reported by Stepan Kasal.
6081 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6083 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6084 change). Patch reported by Ralf Wildenhues in
6085 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6087 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6088 function F exists if the compiler and linker let you compile an
6089 expression like (F != 0). Recent versions of GCC optimize away
6090 the reference to F in that case, since every function address must
6091 be nonzero, so the link succeeds even if F does not exist.
6092 Problem reported by Manu in
6093 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6095 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6096 "Unix". Many uses changed.
6097 (Limitations of Builtins): Explain better why the ! command isn't
6098 portable.
6100 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6102 * lib/autom4te.in (Automake-preselections): Preselect
6103 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6105 2004-05-19 Kevin Ryde <user42@zip.com.au>
6107 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6108 referencing AC_FUNC_STRERROR_R.
6110 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6111 note pessimistic assumption when cross compiling.
6113 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6115 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6116 (until 2004) invoked subcommands with sh -e, contra POSIX.
6117 Reported by Kevin Ryde.
6119 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6121 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6122 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6123 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6124 `test -f " /usr/bin/grep"', which _always_ failed.
6125 (AC_PROG_SED): Ditto bogus PATH fix.
6126 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6127 requires that grep correctly supports _multiple_ `-e' options, rather
6128 than stating only that grep should accept `-e'.
6130 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6132 Port to C99, which requires that 'exit' be declared.
6134 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6135 to ensure that stdlib.h is included.
6136 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6137 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6138 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6139 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6140 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6141 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6142 when using 'exit' in a test; C99 requires that 'exit' be declared.
6144 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6146 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6147 now prefers 'grep' implementations that accept -e.
6148 (Limitations of Usual Tools): Describe problems of traditional
6149 egrep and fgrep with long input lines, and of traditional grep
6150 with -e.
6151 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6152 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6153 All callers changed. Append /usr/xpg4/bin to the PATH, for
6154 Solaris.
6155 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6156 the user with complaints about multiple -e options.
6157 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6158 Define it with AC_PROG_GREP.
6159 * configure.ac (AC_PROG_GREP): Add.
6160 * lib/freeze.mk (GREP): New macro.
6162 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6164 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6165 a possible candidate only after all others fail, rather than
6166 consulting it first. This improves backward compatibility by
6167 better reflecting the way shell selection occurred in previous
6168 versions of Autoconf, and should help to avoid triggering latent
6169 problems in other packages, such as the one in Automake where zsh
6170 is not handled robustly:
6171 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6172 Although it is not Autoconf's responsibility to work around
6173 problems in Automake, it nevertheless makes sense to avoid
6174 introducing unnecessary incompatibilites.
6176 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6177 Gary V. Vaughan <gary@gnu.org>
6179 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6180 how deeply nested we are when a suitable tool is found, set the
6181 ac_path_TOOL_found flag.
6182 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6183 nested we are in this macro. Break out of all 3 nested loops if
6184 ac_path_TOOL_found is set.
6186 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6188 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6189 of the _AS_PATH_WALK loop too if GNU flavor is found.
6191 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6193 * doc/autoconf.texi (Limitations of Make): Update documentation
6194 for `$<'. New entry `Long lines', based on a report from Simon
6195 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6196 paragraph about DJGPP, based on a mail from Richard Dawe.
6198 2004-04-20 Paul Eggert <eggert@twinsun.com>
6200 * tests/c.at (C keywords): Don't assume that GCC supports
6201 "restrict" and "inline", as sufficiently-old GCC versions do not
6202 (also, GCC configured to be in pedantic C89 mode does not).
6203 Problem reported by Sumit Pandya in:
6204 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6206 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6207 consider -g to work if it generates warnings when plain compiles
6208 don't. Problem reported by Braden McDaniel in:
6209 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6211 * doc/autoconf.texi (Slashes): New section, to document a problem
6212 reported by Jim Meyering in:
6213 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6215 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6216 linker output files before linking, to work around IRIX 6 linker bug.
6217 Problem reported by Rainer Orth in:
6218 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6220 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6222 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6223 best tool so far counter rely on the tool path variable name to
6224 avoid checks for one tool being affected by the results of running
6225 the length check on a previous tool.
6227 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6228 match expression argument, as different greps have different
6229 regular expression flavours.
6230 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6231 literals.
6232 (AC_PROG_EGREP): Pass 'EGREP$'.
6233 (AC_PROG_GREP): Pass 'GREP$'.
6235 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6237 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6238 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6240 2004-03-29 Paul Eggert <eggert@twinsun.com>
6242 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6243 Types, Specific Compiler Characteristics, System Services,
6244 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6245 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6246 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6247 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6248 Likewise.
6249 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6250 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6251 AC_TYPE_OFF_T): Likewise.
6252 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6253 Likewise.
6255 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6256 pacify libtool 1.5.2. Fix quoting problems in sed command.
6258 2004-03-28 Paul Eggert <eggert@twinsun.com>
6260 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6261 now defines HAVE_DECL_TZNAME if it is declared, when
6262 HAVE_STRUCT_TM_TM_ZONE is not defined.
6263 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6264 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6265 for HAVE_TZNAME.
6267 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6269 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6270 superfluous backslashing of quotes (") in sed expressions;
6271 thanks to Paul Eggert.
6273 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6275 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6276 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6277 H. F. Beebe for the bug report.
6279 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6281 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6282 quoted -cmdline argument in Portland Group compiler (bug
6283 reported by Jeffrey J. Barteet).
6285 2004-03-25 Kevin Ryde <user42@zip.com.au>
6287 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6288 (Run Time): ... here, where it's now mentioned.
6290 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
6292 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
6293 inherits from language Autoconf-without-aclocal-m4.
6294 (Customizing autom4te): Adjust example; the cache must now be
6295 disabled for language Autoconf-without-aclocal-m4.
6297 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
6298 Nathanael Nerode <neroden@twcny.rr.com>
6300 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
6301 AC_CHECK_TOOLS): Warn if a cross-tool is found without
6302 a prefix.
6303 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6304 AC_CHECK_TARGET_TOOLS): New macros.
6305 * doc/autoconf.texi (Generic Programs): Document
6306 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6307 AC_CHECK_TARGET_TOOLS, and warn for future changes
6308 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
6309 AC_CHECK_TOOLS.
6310 (Specifying Names): Document the reason for these future
6311 behavioral changes.
6312 * tests/mktests.sh: Do not generate tests for the
6313 new macros.
6314 * NEWS: Document these changes.
6316 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6317 they make TeX hang up.
6319 2004-03-15 Paul Eggert <eggert@bogus.example.com>
6321 * NEWS: New macro AC_CHECK_ALIGNOF.
6322 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6323 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6324 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6325 vowel.
6326 (AC_CHECK_ALIGNOF): New macro.
6327 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6328 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6329 those for sizeof.
6331 2004-03-03 Paul Eggert <eggert@twinsun.com>
6333 * bin/Makefile.am (edit): Don't use $< in a context where
6334 POSIX doesn't require support for it. Use $@.in instead.
6335 Problem reported by Anthony N. Frasso in
6336 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6337 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6339 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6341 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6342 from the next generation of Libtool.
6343 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6345 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6347 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6348 is not always thread-safe. Report from Nathanael Nerode.
6350 2004-02-18 Paul Eggert <eggert@twinsun.com>
6352 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6353 problem on QNX reported by Stephen Rasku in
6354 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6356 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6357 $(m4sh_m4f_dependencies); this removes a FIXME.
6358 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6359 (MAINTAINERCLEANFILES): Split into pieces,
6360 one per related section. Add $(srcdir)/wrapper.in.
6362 2004-02-09 Paul Eggert <eggert@twinsun.com>
6364 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6365 AC_SUBST provides no portable way to escape literal newlines.
6367 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6368 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6369 Darwin uses -lcrt2.o and there's little point to cataloging all
6370 the system variants. Partial fix reported by Andreas Waechter in:
6371 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6372 for bug reported by Nelson H. F. Beebe in:

6375 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
6377 * doc/autoconf.texi (AU_DEFUN): Fix English,
6378 suggested by Paul Eggert.
6379 * lib/autoconf/autoupdate.m4: Correct reference to
6380 acobsolete.m4, suggested by Alexandre Duret-Lutz.
6382 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
6384 * bin/autoupdate.in: Define __file__ so that warnings
6385 refer to the correct file.
6386 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6387 the behavior of the third argument.
6388 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6389 correctly the behavior of the third argument. Document
6390 what the three macros that AU_DEFUN defines do. Fix
6391 warning message when the third argument includes $0
6392 (reported by Alexandre Duret-Lutz).
6394 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6395 Eric Sunshine <sunshine@sunshineco.com>
6396 Paul Eggert <eggert@twinsun.com>
6398 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6399 (AS_INIT): Output shell initialization there. Removed optional
6400 parameter. Expand _AS_SHELL_FN_SPY.
6401 (AS_INIT_WITH_SHELL_FN): Removed.
6402 (_AS_SHELL_FN_SPY): New macro.
6403 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6404 macros.
6405 (AS_SHELL_SANITIZE): Remove loop to find better shell
6406 and documentation for the parameter.
6407 (_AS_DETECT_BETTER_SHELL): Move it here.
6408 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6409 (_AS_RUN): Move it here, support testing with eval.
6410 (AS_REQUIRE_SHELL_FN): Require shell functions when
6411 it is used.
6412 (_AS_LINENO_WORKS): Put around braces, we do not
6413 trigger the bash bug anymore.
6414 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6415 use AS_INIT_WITH_SHELL_FN.
6416 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6418 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6420 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6421 * doc/autoconf.texi: Don't say that the third parameter
6422 is broken.
6423 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6424 (AU_DEFUN): Honor the third parameter, create autoupdate
6425 macros with AU_DEFINE.
6426 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6427 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
6428 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6429 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
6430 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

6433 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
6434 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
6435 * lib/autoconf/status.m4: Remove FIXME.
6436 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
6437 that the macro is not present anymore in the updated
6438 configure.ac.
6439 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
6440 of autoupdate.
6442 2004-01-28 Paul Eggert <eggert@twinsun.com>
6444 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
6445 copyright years.
6446 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6447 2003 (except 1997) to the list of copyright years. This undoes
6448 the 2003-05-22 change, which removed the older years from the list.
6449 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6451 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6452 Albert Chin-A-Young <china@thewrittenword.com>
6454 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6455 grep or ggrep program in PATH that accepts as long lines as
6456 possible.
6457 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6458 AC_PROG_GREP.
6459 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6460 egrep and fgrep respectively if $GREP -E/-F don't work.
6461 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6462 _AC_PROG_GREP, and AC_PROG_SED.
6463 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6464 longest input length accepted by a command.
6465 (AC_PROG_SED): Use it.
6466 * doc/autoconf.texi (Particular Programs): Document the changes.
6467 * NEWS: Updated.
6469 2004-01-27 Paul Eggert <eggert@twinsun.com>
6471 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6472 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6473 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6474 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6476 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6477 bin/autoconf.in, config/Makefile.in, config/config.guess,
6478 config/config.sub, config/install-sh, config/mdate-sh,

6489 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6490 tests/actypes.at: Regenerate and/or sync with original
6491 sources.
6493 2004-01-26 Paul Eggert <eggert@twinsun.com>
6495 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6496 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6497 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6498 not <inttypes.h>. Problem reported by Tim Mooney in
6499 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6500 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6501 Likewise.
6503 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6504 otherwise "make check" fails because it forbids cmp (I guess
6505 because cmp treats files as binary on DOS-like systems).
6507 * tests/mktests.sh: Update copyright date to 2004, since some tests
6508 have changed in 2004.
6510 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6512 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6513 non-truncating sed or gsed program in PATH.
6514 * tests/acprograms.at: Add it.
6515 * doc/autoconf.texi (Particular Programs): Document it.
6516 * NEWS: Updated.
6518 2004-01-15 Paul Eggert <eggert@twinsun.com>
6520 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6521 -std1 disables some useful extensions on Tru64. Problem reported
6522 by N. Lichtmaier in
6523 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6525 2004-01-14 Paul Eggert <eggert@twinsun.com>
6527 * doc/autoconf.texi (Programming in M4sh): Document that
6528 AS_MKDIR_P succeeds if the destination is a symbolic link
6529 to an existing directory.
6530 (Limitations of Usual Tools): Note that mkdir -p might not
6531 succeed on symlinks to directories.
6533 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6535 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6536 * bin/autoheader.in: Grammar fix in message.
6537 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6538 Test for dir before calling mkdir -p. (trivial changes)
6540 2004-01-13 Eric Blake <ebb9@byu.net>
6542 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6543 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6545 2004-01-10 Jim Meyering <jim@meyering.net>
6547 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6549 2004-01-09 Paul Eggert <eggert@twinsun.com>
6551 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6552 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6553 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6554 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6555 AC_COMPILE_IFELSE, since we now assume our caller invokes
6556 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6557 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6558 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6559 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6561 2004-01-07 Paul Eggert <eggert@twinsun.com>
6563 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6564 `"'...'"`, as it's confusing (and I suspect it may not work on
6565 some platforms). The code was incorrect anyway, as it assumed
6566 that \$ evaluated to itself in that context. Reported by
6567 Alexandre Duret-Lutz.
6569 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6571 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6572 and _LT_AC_TAGCONFIG.
6574 2004-01-06 Paul Eggert <eggert@twinsun.com>
6576 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6577 example, and add more examples. Reported by Eric Sunshine.
6579 2004-01-05 Paul Eggert <eggert@twinsun.com>
6581 * doc/autoconf.texi (Limitations of Usual Tools):
6582 Remove warning against "rm -fr" introduced yesterday; it
6583 was a false alarm.
6585 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6586 autoscan, autoupdate, ifnames): Don't use chmod -w.
6587 * lib/Makefile.am (autom4te.cfg): Likewise.
6588 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6589 "chmod -w".
6591 2004-01-04 Paul Eggert <eggert@twinsun.com>
6592 Paolo Bonzini <bonzini@gnu.org>
6594 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6595 by doing lineno substitution only on lines containing "$LINENO".
6597 2004-01-04 Paul Eggert <eggert@twinsun.com>
6599 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6600 Use "rm -f" to remove conftest.sed, not plain "rm".
6601 Bug reported by David Relson in
6602 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6604 * Makefile.am (autom4te-update):
6605 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6606 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6607 * doc/autoconf.texi (Guidelines): Likewise.
6608 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6613 * tests/Makefile.am (clean-local): Likewise.
6614 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6615 srcdir): Likewise.
6616 * doc/autoconf.texi (Limitations of Usual Tools):
6617 Warn against "rm -fr".
6619 2004-01-03 Paul Eggert <eggert@twinsun.com>
6621 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6622 -c -o might not work. From a suggestion by Kevin Ryde.
6623 (C Compiler, Generating Sources, Limitations
6624 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6625 Don't put '-o' after non-options, as POSIX doesn't allow this.
6626 Mention that cc's name might be gcc or c89 or whatever.
6628 2004-01-04 Kevin Ryde <user42@zip.com.au>
6630 * doc/autoconf.texi: Add various further index entries.
6632 2003-12-29 Paul Eggert <eggert@twinsun.com>
6634 * bin/autoreconf.in (autoreconf_current_directory):
6635 Fix typo: mkdir without umask arg.
6637 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6639 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6640 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6641 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6642 explanation clearer.
6644 2003-12-24 Andreas Schwab <schwab@suse.de>
6646 * doc/autoconf.texi (Default Includes): Fix misspelling of
6647 AC_INCLUDES_DEFAULT.
6649 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6651 * configure.ac: Test if sh -n works.
6652 * configure: Regenerate.
6653 * tests/atlocal.in: Store the result here.
6654 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6655 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6656 of explicitly testing.
6657 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6658 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6659 * tests/tools.at (Syntax of the shell scripts): Simplify
6660 using AT_CHECK_SHELL_SYNTAX.
6661 (Syntax of the Perl scripts): Remove definition of
6662 AT_CHECK_PERL_SYNTAX.
6664 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6666 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6667 stderr to /dev/null.
6668 * bin/autoconf.in: Regenerate.
6669 * bin/wrapper.in: Regenerate.

6673 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6674 Extracted from AS_SHELL_SANITIZE.
6675 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6676 macros.
6677 (AS_SHELL_SANITIZE): Move reinvocation code from
6678 _AS_LINENO_WORKS, use it to find out if shell
6679 functions work.
6680 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6681 does not work.
6682 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6683 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6684 was called.

6693 * config/announce-gen (&print_locations, &print_signatures)
6694 (&sizes): New.
6695 Use them.

6697 them on the fly.
6699 2003-11-24 Akim Demaille <akim@epita.fr>
6701 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6729 parameter of AU_DEFUN.
6730 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
6731 (AU_DEFUN): Remove the third parameter, it was not used.
6732 Use AC_DEFUN directly, not AU_DEFINE.
6733 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
6734 the expanded body, consistently with other macros such as AC_USG.
6736 2003-11-17 Paul Eggert <eggert@twinsun.com>
6738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6739 into the initial confdefs.h, to work around a bug in NextStep 3.3
6740 patch 3 reported by Eric Sunshine.
6742 2003-11-15 Kevin Ryde <user42@zip.com.au>
6744 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6745 than $target since the latter is not usual, add guidelines on when to
6746 use or not use the system type.
6748 2003-11-12 Derek Price <derek@ximbiot.com>
6750 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6751 typo misrepaired by an auto-spellcheck.
6753 2003-11-12 Akim Demaille <akim@epita.fr>

6756 --force-missing unless it actually supports it.
6757 From Debian #219336.
6759 2003-11-12 Akim Demaille <akim@epita.fr>
6761 * configure.ac: Bump to 2.59a.

6770 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
6771 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
6772 and ac_abs_top_srcdir are absolute paths.

6779 2003-11-05 Kevin Ryde <user42@zip.com.au>

6923 Problems reported by Eric Sunshine.
6925 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6927 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6928 -mGLOB_options_string stuff for Intel ifc, which can cause

6952 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6953 cache variable instead of $G77 to decide whether to include -O2,
6954 since $G77 is specific to Fortran 77.

6958 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6959 free" flag. Re-order flags tested into rough order of popularity.
6961 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6963 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6964 arguments so that it can be used with syntax identical to
6965 AC_PROG_F77, and so that we can more easily decide to
6966 remove/deprecate the DIALECT optional argument in the future if it
6967 proves troublesome.
6968 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6969 non-freeform-supporting compilers. Document freeform flags.
6971 2003-10-03 Akim Demaille <akim@epita.fr>

6983 2003-10-03 Akim Demaille <akim@epita.fr>
6985 * configure.ac: Quotation and formatting changes.

7032 Problem reported by Lars J. Aas in
7033 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7034 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7035 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7036 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7038 2003-09-26 Akim Demaille <akim@epita.fr>
7040 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7041 directory for AC_CONFIG_COMMANDS' first argument exists.
7042 This makes valid the invocation of _AC_SRCPATH that follows.
7043 Reported by Eric Sunshine.
7044 * doc/autoconf.texi (Configuration Commands): Adjust.
7046 2003-09-26 Akim Demaille <akim@epita.fr>
7048 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7049 Reported by Ralf Corsepius.

7053 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7054 arguments.
7055 Actually, use AU_ALIAS.
7056 From Bruno Haible.

7065 2003-09-26 Akim Demaille <akim@epita.fr>
7067 The test suite are sometimes assigning timings incorrectly.
7068 Reported by Henk Krus.
7069 Diagnosed by Nicolas Joly.
7071 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7072 AT_help_all.
7073 Instead of making AT_help a sequence of assignments to grow
7074 $at_help_all, just make AT_help_all be the growing contents of
7075 $at_help_all, and make a single assignment in...
7076 (AT_INIT): here.
7077 (at_times_skip): Flip the meaning and rename as...
7078 (at_times_p): this.
7079 (AT_INIT): When summarizing the test that ran, remove
7080 $at_times_file after use, and check it is present before trying to
7081 use it.
7083 2003-09-25 Akim Demaille <akim@epita.fr>
7085 Version 2.57d.

7089 (ifnames): chmod -w.
7090 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7091 executables, not bin/ executables! Otherwise all the magic needed
7092 to find non installed files is turned off. This caused a failure
7093 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7094 as found in its environment (sent by tests/autoreconf): pointing
7095 to bin/autom4te that could not find its files.
7096 * tests/mktests.sh: Force the replacement of generated files, for
7097 the sake of "mv" program that are interactive when overwriting a
7098 -w file.
7099 * config/install-sh: Upgrade from CVS Automake.
7101 2003-09-23 Paul Eggert <eggert@twinsun.com>

7104 versus test -L issues.
7106 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7107 Paul Eggert <eggert@twinsun.com>
7109 Trivial change to support GCC's configuration procedure.
7110 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7111 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7112 about inconsistency if the preprocessor is set to give errors for
7113 any warning.
7114 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7116 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

7139 * doc/autoconf.texi (Header Portability): linux/random.h.
7140 From Peter Hendrickson.
7142 2003-09-10 Akim Demaille <akim@epita.fr>
7144 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7145 willing to edit the output files.
7147 2003-09-10 Akim Demaille <akim@epita.fr>
7149 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7150 and AC_FC_FREEFORM.
7151 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7152 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

7168 Improve the accuracy of the wording about obsolescence.
7169 From a suggestion by Ian Lance Taylor in
7170 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7172 2003-09-05 Paul Eggert <eggert@twinsun.com>
7174 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7175 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7177 2003-09-04 Akim Demaille <akim@epita.fr>
7179 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7180 AC_FUNC_WAIT3.
7182 2003-09-04 Akim Demaille <akim@epita.fr>
7184 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7185 (freeze): When exiting, use $exit_code.

7188 2003-09-04 Akim Demaille <akim@epita.fr>
7190 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7192 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7194 Add support for newer Fortran dialects. The F77 interface is
7195 unchanged, and continues to support Fortran 77. New FC macros
7196 correspond to all the old F77 macros, with output variables FC,
7197 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7198 available dialect, but older dialects can be specified. There are
7199 new macros AC_FC_SRCEXT to set the source extension, and
7200 AC_FC_FREEFORM to accept free-form source files.
7202 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7203 New macros.
7204 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

7220 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7221 Rewrite in terms of the above.
7222 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7223 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

7227 2003-09-02 Paul Eggert <eggert@twinsun.com>
7229 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7230 Document problems with timestamp resolution that 'make', 'cp -p', and
7231 'touch -r' have.
7233 2003-08-27 Akim Demaille <akim@epita.fr>
7235 * tests/m4sugar.at (cross_warning): Make sure to enable the
7236 output, so that we can track spurious m4sugar output.
7237 * tests/local.at: Require 2.57.
7238 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7239 are defaulted by AT_CHECK anyway.
7240 Use AT_CHECK_AUTOM4TE.
7241 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7242 missing dnl.
7244 2003-08-27 Akim Demaille <akim@epita.fr>
7246 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7247 when -Wobsolete is set.
7248 Set it on by default.
7249 Suggested by Klee Dienes.

7283 Version 2.57b.
7285 * Makefile.cfg (local-checks-to-skip): New.
7286 * Makefile.maint (local-check): Rename as...
7287 (local-checks-available): this.
7288 (local-check): New.
7290 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7291 * configure.ac: Require Automake 1.7.6.
7293 2003-08-22 Akim Demaille <akim@epita.fr>
7295 Output stack traces in warnings.
7297 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7298 Replace the former...
7299 (m4_warn): Pass the call stack to _m4_warn.
7300 * bin/autom4te.in: Adjust to output the call stack.
7301 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7303 2003-08-22 Akim Demaille <akim@epita.fr>
7305 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7306 * bin/autom4te.in: Adjust.
7308 2003-08-21 Akim Demaille <akim@epita.fr>
7310 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7311 (&verbose): Remove.
7312 (&getopt): Adjust the note and verb channels, depending upon
7313 --verbose.
7314 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7315 * bin/autoupdate.in: Adjust.
7316 Use &verb, not &verbose.
7318 2003-08-21 Akim Demaille <akim@epita.fr>
7320 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7321 &parse_WARNINGS.
7322 ($help): Use Autom4te::ChannelDefs::usage.
7323 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7324 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7326 2003-08-21 Akim Demaille <akim@epita.fr>
7328 First stab at preserving warnings between calls to autom4te,
7329 including when the cache is used.
7331 There are still several issues: (i) there are too many runs of m4
7332 (one for include, one for warnings, and some more), (ii) warnings
7333 spreading on several lines are not handled gracefully, (iii) the
7334 code meant to have the call stack display for errors does not work
7335 (its handling should move from m4 to autom4te).
7337 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7338 Use them.
7339 (@preselect): Add m4_warn.
7340 ($exit_status): Remove, use $exit_code.
7341 ($help): Use Autom4te::ChannelDefs::usage.
7342 (&handle_m4): No longer define the m4_warnings.
7343 At each run, extract and report the warnings.
7344 Always cache the result, including if the exit status is on
7345 failure, since if nothing changes, we should result in the same
7346 failure, hence we can use the cache.
7347 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7348 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7349 Remove.
7350 (m4_warn): Redefine as a do-nothing: it is its invocation that
7351 matters, as warnings are now reported via traces.
7352 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7353 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7354 the latter reveals calls to the former.
7356 Adjust the tests.
7358 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7360 2003-08-21 Akim Demaille <akim@epita.fr>
7362 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7363 Use them.
7365 2003-08-21 Akim Demaille <akim@epita.fr>
7367 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7368 forward order.
7369 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7370 (&parse_warnings): Accept a list of warning requests.
7371 (&usage): Return a string, not a side effect.
7372 (cross): New warning category.
7374 2003-08-21 Akim Demaille <akim@epita.fr>
7376 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7377 (&require_configure_ac): Accept an optional directory argument.
7378 ($configure_ac): Remove.
7379 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7380 (&catfile): Remove.
7381 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7382 * bin/autoscan.in: Adjust.
7384 2003-08-20 Akim Demaille <akim@epita.fr>
7386 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7387 Reported by Alexandre Duret-Lutz.
7389 2003-08-20 Akim Demaille <akim@epita.fr>
7391 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7392 * bin/autom4te: Adjust.
7393 In particular, be Autoconf tools are really silent when properly
7394 working, bind the verbosity of the 'note' channel to $verbose.
7395 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7396 (&xsystem, &contents): Remove, since they are exported by...
7397 * lib/Autom4te/FileUtils.pm: this.
7398 More perldoc.
7399 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7400 * lib/Autom4te/FileUtils.pm: here.
7402 2003-08-20 Akim Demaille <akim@epita.fr>
7404 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7405 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7406 from CVS Automake.
7408 2003-08-20 Akim Demaille <akim@epita.fr>
7410 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
7411 (autom4te-update): New.
7412 * Makefile.cfg (update): Bind autom4te-update.
7414 2003-08-19 Derek Price <derek@ximbiot.com>
7416 * lib/autotest/general.m4: Comment various HELP_* diversions.
7417 (PARSE_ARGS_BEGIN): New section for option parsing related
7418 initialization.

7426 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
7428 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7430 * lib/autom4te.in (Automake-preselections): Preselect
7431 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7432 and m4_sinclude.
7434 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7436 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7437 (Autoconf-without-aclocal-m4): ... this new language.
7438 * doc/autoconf.texi (autom4te Invocation): Mention
7439 Autoconf-without-aclocal-m4.

7455 2003-08-14 Derek Price <derek@ximbiot.com>
7457 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7458 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7459 shorter column three. Add DESCRIPTION to log file content.
7461 2003-08-13 Derek Price <derek@ximbiot.com>
7463 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7464 output.
7466 2003-08-12 Derek Price <derek@ximbiot.com>
7468 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7469 (AT_CHECK_NOESCAPE): Move core functionality to...
7470 (_AT_CHECK): ...this new macro.
7472 2003-08-07 Derek Price <derek@ximbiot.com>
7474 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7475 (AT_CHECK_NOESCAPE): ...to this new macro.
7477 2003-07-31 Paul Eggert <eggert@twinsun.com>
7479 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7480 in Bash 2.01. Problem reported by Brian Gough in
7481 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7483 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7485 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7486 -lcrt1.o, for OS X. (trivial change)
7488 2003-07-07 Paul Eggert <eggert@twinsun.com>
7490 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7491 inside '#ifndef __cplusplus'. Problem reported by
7492 Bob Friesenhahn.
7494 2003-07-06 Bill Clarke <llib@computer.org>
7496 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7497 'long', not 'int', for benefit of Sun's recent C++ compilers
7498 (trivial change). See:
7499 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7500 (This really should be 'intptr_t', not 'long', but that would
7501 take more work.)
7503 2003-06-25 Akim Demaille <akim@epita.fr>
7505 * lib/Makefile.am (autom4te.cfg): Make it read only.
7506 Depend on Makefile since it contains substitutions.
7507 From Paolo Bonzini.
7508 * lib/autom4te.in (args): Add local.at? for Autotest args.
7509 This change was made on autom4te.cfg which is generated.
7510 Reported by Raja R. Harinath.
7512 2003-06-25 Akim Demaille <akim@epita.fr>
7514 * doc/autoconf.texi (Header Portability): sys/mount.h.
7515 From Gareth McCaughan.
7517 2003-06-23 Akim Demaille <akim@epita.fr>
7519 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7520 not all of them. This fixes 1. the fact that when testing
7521 Autoconf there are many many config.log, 2. the incorrect use of
7522 top_srcdir to find config.log.
7523 Don't mix the detailed output of failed test with the summary of
7524 failures. Rather, append detailed log afterwards.
7526 2003-06-23 Akim Demaille <akim@epita.fr>
7528 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7529 always run: output config.log on $at_group_log.
7531 2003-06-23 Akim Demaille <akim@epita.fr>
7533 * tests/torture.at (#define header templates): Don't use quotes in
7534 C++ comments as it puzzles Emacs' sh font-lock-mode.
7536 2003-06-23 Akim Demaille <akim@epita.fr>
7538 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7539 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7540 * tests/atspecific.m4: Rename as...
7541 * tests/local.at: This.
7542 * tests/suite.at: Move the globals into...
7543 * tests/local.at: here.
7544 * tests/Makefile.am: Adjust.
7545 * doc/autoconf.texi (testsuite Scripts): Adjust.
7547 2003-06-21 Kevin Ryde <user42@zip.com.au>
7549 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7550 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7551 ensuring we add -std1 for full-ANSI.
7553 * doc/autoconf.texi (hdrindex): New macro.
7554 Add index entries for portability of various standard header files.
7556 2003-06-20 Akim Demaille <akim@epita.fr>
7558 * configure.ac: Bump to 2.57b.
7560 2003-06-20 Akim Demaille <akim@epita.fr>
7562 Version 2.57a.
7564 2003-06-20 Akim Demaille <akim@epita.fr>
7566 * bin/autom4te.in: Don't rely on $HOME being defined.
7567 Reported by Marc Espie as PR/233.
7569 2003-06-20 Akim Demaille <akim@epita.fr>
7571 * lib/autotest/general.m4: Use at_times_file only if used.
7572 From Nicolas Joly.
7574 2003-06-20 Akim Demaille <akim@epita.fr>
7576 * config/config.guess, config/config.sub, config/elisp-comp,
7577 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7578 Update from masters.
7580 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7582 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7583 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7584 (TEST_SCRIPT): New diversion.
7585 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7586 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7587 (AT_INIT): Support for expected failures.
7589 2003-06-02 Akim Demaille <akim@epita.fr>
7591 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7592 changes.
7593 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7594 Autoconf nor Automake.
7595 (&contents): New, from Automake.
7596 PODify.
7598 2003-05-28 Paul Eggert <eggert@twinsun.com>
7600 * NEWS, doc/autoconf.texi (Particular Functions),
7601 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7602 is the inverse of localtime.
7604 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7606 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7607 (handle_exec_errors): New function. Work around $! being
7608 altered by WEXITSTATUS.
7609 (xqx, xsystem): Use handle_exec_errors.
7611 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7613 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7614 Do not call `_exit()', simply modify `$?'.
7615 (xsystem): Reset $! before running system, and check it afterward.
7616 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7617 63 for version mismatches.
7619 2003-05-23 Akim Demaille <akim@epita.fr>
7621 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7622 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7623 the middle of a line).
7624 * lib/m4sugar/m4sugar.m4: Likewise.
7625 Remove useless spaces in comments.
7627 2003-05-23 Akim Demaille <akim@epita.fr>
7629 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7630 exit 63, so that we (or Automake's "missing") can tell the
7631 difference with a plain failure.
7632 * doc/autoconf.texi (Notices): Adjust.
7634 2003-05-23 Akim Demaille <akim@epita.fr>
7636 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7637 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7638 White spaces cleanup.
7640 2003-05-22 Jim Meyering <jim@meyering.net>
7641 Paul Eggert <eggert@twinsun.com>
7643 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7644 Remove `#include <stdlib.h>' from the list; we should never
7645 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7646 resulting namespace pollution would cause other tests to fail.
7647 Configure scripts run with some older versions of g++ and HP's
7648 aCC would fail due to such an #include. Problems reported by
7649 Matthew Mueller in <http://bugs.debian.org/120704> and by
7650 Keith Bostic in
7651 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7652 In the test, use the test declaration before including <stdlib.h>,
7653 as that's closer to how it'll be used.
7655 2003-05-23 Akim Demaille <akim@epita.fr>
7657 * doc/autoconf.texi (Header Portability): ucred.h.
7658 From Ian Redfern.
7660 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7662 Overhaul Autotest's logging: generate separate log files
7663 in testsuite.dir/NNN/testsuite.log, and append them to
7664 testsuite.log instead of re-running the test verbosely.
7666 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7667 file descriptor, write 0 to at_status_file instead of setting
7668 at_status=0, initialize some new variables (at_status_file,
7669 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7670 to rerun the tests, instead append the at_group_log to the
7671 at_suite_log when a test fails.
7672 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7673 with the AS_MESSAGE_LOG_FD redirected to stdout.
7674 (AT_CLEANUP): save the output status in $at_status_file
7675 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7676 its original place.
7677 (AT_CHECK): since tests are run with a redirected stdout,
7678 and used to be re-run in verbose mode, turn some $at_verbose
7679 into echo, and don't redirect the output of testing stdout
7680 and stderr.
7682 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7683 the name of the debugging directory and information about
7684 its contents.
7686 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7688 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7689 parameter.

7773 user name space clashes.
7774 Reported by Bruno Haible.
7776 2003-05-16 Akim Demaille <akim@epita.fr>

7801 and truncate.
7803 2003-05-06 Akim Demaille <akim@epita.fr>
7805 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7806 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7807 by aclocal.m4 is changed it might require the importing of another
7808 m4 extension file, i.e., aclocal must be run.
7810 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7811 (&parse_args): Use --force with aclocal if required and supported.
7812 (&autoreconf_current_directory): Use &run_aclocal.
7814 2003-05-06 Akim Demaille <akim@epita.fr>
7816 Lock autom4te's cache.
7818 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7819 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7820 argument instead of a file name, so that the request file remains
7821 open during the whole autom4te run.
7822 ($icache_file): New.
7823 (&freeze): Lock the $icache_file.
7825 2003-04-29 Derek Price <derek@ximbiot.com>
7827 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7828 seperator with m4_append_uniq(). It doesn't work.
7829 (AT_CLEANUP): Add `;' to end of at_help_all.
7830 (AT_INIT): Allow --keywords to be specified more than once. When
7831 grepping $at_help_all for keywords, use the field and keyword
7832 seperators to ensure a complete keyword match. Alter at_prev handling
7833 to support the new --keywords behavior.
7835 2003-04-27 Karl Berry <karl@freefriends.org>
7837 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7838 align better with others. I also made some of the individual
7839 entries on one line, for brevity and to make it easier for me to
7840 sort my dir-example file in the Texinfo distribution :).
7842 2003-04-12 Jim Meyering <jim@meyering.net>

7857 * GNUmakefile (SHELL): Don't assume sh is in /bin/.
7858 From Ilya Zakharevich.
7860 2003-04-08 Akim Demaille <akim@epita.fr>
7862 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
7863 net/if.h, stdlib.h.

7885 2003-03-31 Derek Price <derek@ximbiot.com>
7887 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7888 which removed the main loop.
7889 Thanks to Akim Demaille.
7891 2003-03-29 Akim Demaille <akim@epita.fr>

7907 header causes problems.
7909 2003-03-28 Akim Demaille <akim@epita.fr>
7911 * tests/torture.at (Configuring subdirectories): Require aclocal
7912 1.4, otherwise the test fails, as it does support configure.ac.
7913 This fixes the "test 40 failed" bug reports.
7915 2003-03-28 Akim Demaille <akim@epita.fr>
7917 * doc/autoconf.texi (C Compiler): `#line' portability.
7918 From Paul Eggert and Nelson H. F. Beebe.
7920 2003-03-27 Derek Price <derek@ximbiot.com>
7922 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7923 layout in order to allow scripting around test groups.
7925 2003-03-27 Derek Price <derek@ximbiot.com>
7927 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7928 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7929 use new diversions in preparation for accepting new arguments and

7935 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
7936 obsolete AC_HELP_STRING.
7937 (AC_HELP_STRING): AU_DEFUN to...
7938 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7939 * tests/m4sh.at (AS_HELP_STRING): New test.

7943 2003-03-26 Derek Price <derek@ximbiot.com>
7945 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7946 sense. Verbosify the diversion definitions comment.

7950 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

7985 Tru64 make in the "target lookup" section.
7986 (Automake): Automake 1.5+ no longer requires special tools to be
7987 present on the developer's host.

8003 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
8004 to cope with DOS-style absolute paths, when constructing
8005 ${ac_make}.
8007 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8008 When constructing paths with IFS=:, quote the path. If we're
8009 constructing a DOS-style absolute path, we don't want to split it
8010 on the colon.
8012 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8013 in description.
8015 2003-02-25 Pavel Roskin <proski@gnu.org>

8027 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8028 to fix a mismatch between example and discussion.
8030 2003-02-24 Kevin Ryde <user42@zip.com.au>
8032 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8033 format starting with "-".
8035 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8037 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8038 is not portable inside Makefile.
8040 2003-02-20 Akim Demaille <akim@epita.fr>
8042 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8043 compiler says yeah, but preproc says nope, compiler is right.
8044 Conversely, prompt the reader to send a bug report to the
8045 maintainers of the package, not of Autoconf.
8047 2003-02-20 Klee Dienes <kdienes@apple.com>

8060 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8061 innocuous variant befor including <limits.h> or <assert.h>. This
8062 works around a bug reported by Albert Chin: HP-UX 11i
8063 (and earlier versions) have a <limits.h> that declares
8064 gettimeofday and many other functions.
8066 2002-12-03 Paul Eggert <eggert@twinsun.com>
8068 Version 2.57.
8070 * NEWS, configure.ac: Update version.
8072 * doc/fdl.texi: Upgrade to FDL version 1.2.
8074 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8075 nontrivially in main's body, so that f's external declaration is
8076 not optimized away in AIX. This should fix the bug reported by
8077 Martin Frydl in
8078 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8080 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8081 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8082 defined, to support freestanding compilers. This should fix the
8083 bug reported by Momchil Velkov in
8084 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8086 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8087 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
8088 obsolete AC_CHECK_TYPE. The missing empty arg was reported
8089 by Simon Josefsson in

8092 * Makefile.maint (www-gnu): New macro.
8093 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8094 the location has moved.
8096 2002-12-02 Martin Frydl <martin@systinet.com>
8098 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8099 \(.*\) match is too long and there is something more to be checked.
8100 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8102 2002-11-15 Akim Demaille <akim@epita.fr>
8104 Version 2.56.
8106 * config/install-sh: chmod +x.
8107 From Paul Eggert.
8108 * config/move-if-change: Indenting changes.
8109 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
8110 * configure.ac (AM_INIT_AUTOMAKE): here.
8111 Require 1.7.1.
8113 2002-11-14 Akim Demaille <akim@epita.fr>
8115 Version 2.55.
8117 * config/config.guess, config/config.sub, config/install-sh:
8118 Update from masters.
8120 2002-11-14 Akim Demaille <akim@epita.fr>
8122 * Makefile.maint: Sync with Bison, i.e.:
8123 (po-check): Scan .l and .y files instead of the
8124 .c and the .h files that they generate. This fixes the bug
8125 reported by Tim Van Holder in:
8126 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8127 Look for N_ as well as for _. Try to avoid matching #define for
8128 N_ and _.
8129 From Paul Eggert.
8131 2002-11-14 Akim Demaille <akim@epita.fr>
8133 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8134 From Paul Eggert and Albert Chin-A-Young.
8136 2002-11-14 Akim Demaille <akim@epita.fr>
8138 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8139 From Paul Eggert and Albert Chin-A-Young.
8141 2002-11-14 Kevin Ryde <user42@zip.com.au>
8143 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8144 than assigning in main, to avoid HP cc +O3 optimizing it away.
8146 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8148 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8149 option. Process --recheck after parsing all options. Pass -q
8150 option to configure on --recheck.
8151 (AC_OUTPUT): Pass -q from configure to config.status.
8152 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8153 arguments to record.
8154 * doc/autoconf.texi (config.status Invocation): Document
8155 config.status -q option.
8157 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
8159 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
8160 Makefile.in if Makefile.am exists.
8161 (output): Strip `.am' from Makefiles. Don't
8162 output AC_CONFIG_FILES if no Makefiles were found.
8164 2002-11-07 Akim Demaille <akim@epita.fr>
8166 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
8167 (local_updates): New.
8168 * Makefile.maint: Update, from CVS Bison.
8169 (local_updates): New.
8171 2002-11-06 Akim Demaille <akim@epita.fr>
8173 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
8174 declaration in extern "C" too.
8175 Reported by Roberto Bagnara.
8177 2002-11-06 Akim Demaille <akim@epita.fr>
8179 * tests/torture.at (Configuring subdirectories): Don't use grep
8180 -w.
8181 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8182 Reported by Ezra Peisach.
8184 2002-11-05 Akim Demaille <akim@epita.fr>
8186 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8187 Remove.
8188 We _have_ to stop using the old compatibility scheme that tried to
8189 avoid useless backslashes because Libtool 1.4.3 contains a
8190 AC_DEFINE([error_t], [int],
8191 [Define to a type to use for \`error_t' if it is not
8192 otherwise available.])
8193 We _have_ to quote the single quote and backslashes with \. The
8194 old compatibility scheme saw that ` was backslashed, and therefore
8195 did not quote the single quote. Hence before this patch, Autoconf
8196 was not compatible with Libtool.
8198 2002-11-04 Paul Eggert <eggert@twinsun.com>
8200 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
8201 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
8202 LC_NAME, LC_PAPER, LC_TELEPHONE.
8203 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
8205 2002-11-04 Akim Demaille <akim@epita.fr>
8207 Version 2.54c.
8209 * Makefile.maint (update, cvs-update, po-update, do-po-update):
8210 New.
8211 * config/texinfo.tex: Update.
8213 2002-11-03 Akim Demaille <akim@epita.fr>
8215 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8216 from...
8217 (&autoreconf): here.
8218 ($help, $make, &parse_args, &autoreconf_current_directory):
8219 Support -m/--make.
8220 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8222 2002-10-31 Bruno Haible <bruno@clisp.org>
8224 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

8228 to ac_cv_func_realloc_0_nonnull.
8229 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
8231 2002-10-31 Akim Demaille <akim@epita.fr>
8233 The test suite was no longer checking for trailing envvars and files.
8235 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
8236 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
8238 2002-10-31 Akim Demaille <akim@epita.fr>
8240 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display

8294 * tests/torture.at (Deep Package): New test.

8528 2002-10-22 Akim Demaille <akim@epita.fr>
8530 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8534 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8535 strings.
8537 2002-10-22 Akim Demaille <akim@epita.fr>
8539 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8586 longer required can still cause errors.
8587 Reported by Alexandre Duret-Lutz.
8589 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8590 to frozen files in @ARGV, as @ARGV must remain being a list of

8592 (&files_to_options): New function.
8593 (&freeze): Use &error.
8594 (&up_to_date): If a file that was included according to the cache
8595 is no longer there, then the output is out dated.
8596 (&main): Don't even check whether a file is up to date is anyway
8597 --force is given.
8598 * tests/tools.at (autom4te cache): New.
8600 2002-10-16 Akim Demaille <akim@epita.fr>

8605 Factor some code.
8606 (&autoreconf): Report the directories we enter *and leave*, so
8607 that error messages can be easily located, and use GNU Make
8608 format, so that Emacs' compile mode understands us.
8609 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8610 if some file was changed instead of `print'.
8611 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8624 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8625 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

8645 file name to enable parallel executions.
8646 From Sam Varshavchik.
8648 2002-10-08 Akim Demaille <akim@epita.fr>
8650 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8651 aclocal invocation, as Gettext macros might not be visible to
8652 aclocal.
8653 Instead of blindly running autopoint, scan configure.ac (not the
8654 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8655 Reported by Paul D. Smith.
8657 2002-10-08 Paul Eggert <eggert@twinsun.com>
8659 Work around problems found when POSIXLY_CORRECT=1 is set.
8660 None of this seems to have anything to do with POSIX, really,
8661 but it's how Perl getopt works.
8662 * bin/autom4te.in (parse_args): Configure GetOpt with
8663 "permute", too.
8664 * doc/autoconf.texi (Invoking autom4te):
8665 --warning -> --warnings.

8685 2002-09-28 Akim Demaille <akim@epita.fr>
8687 * tests/torture.at (Configuring subdirectories): Be robust to
8688 users who use config.site to require for a cache: in this case,
8689 the two last configure runs, using two different sets of
8690 arguments, trigger a legitimate error.
8692 2002-09-28 Akim Demaille <akim@epita.fr>
8694 * tests/m4sh.at (Functions Support, Functions and return Support):
8695 New.

8708 (tm_zone): Move their rules to...
8709 * lib/autoconf/types.m4: here, using AN_ macros.
8710 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8711 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8712 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8713 * lib/autoconf/programs.m4: here.

8725 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8726 (.m4.m4f): Don't pass --prepend-include, since that's done by
8727 tests/autom4te itself.

8732 2002-09-28 Akim Demaille <akim@epita.fr>
8734 * bin/autoscan.in (@kinds): Make them singular.
8735 Adjust all uses.
8736 (&init_tables): When --debug, report the list of rules to ease
8737 tracking changes in autoscan.list.
8738 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8740 2002-09-28 Akim Demaille <akim@epita.fr>
8742 * lib/autoscan/functions, lib/autoscan/headers,
8743 * lib/autoscan/identifiers, lib/autoscan/makevars,

8746 * bin/autoscan.in (&init_tables): Adjust.
8748 2002-09-28 Akim Demaille <akim@epita.fr>
8750 * lib/autoscan/functions, lib/autoscan/headers,
8751 * lib/autoscan/identifiers, lib/autoscan/makevars,
8752 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8753 `functions' line is now prefixed with `function:'.
8754 * bin/autoscan.in (&init_tables): Adjust.
8756 2002-09-28 Akim Demaille <akim@epita.fr>
8758 From now on, autoscan files must always map a macro name to a
8759 word: there is no `default' macro for autoscan.
8761 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8762 all.
8763 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8764 explicit.
8766 2002-09-28 Akim Demaille <akim@epita.fr>
8768 * bin/autoscan.in (%c_keywords): Remove.
8769 (&used): Keep only track of the words we might be interested in.
8770 (&output_kind): It is no longer needed to look for non active
8771 checks.
8773 2002-09-27 Akim Demaille <akim@epita.fr>
8775 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8780 2002-09-27 Akim Demaille <akim@epita.fr>

8783 from /tmp.
8784 Thanks to Bill Moseley and Paul Eggert.
8785 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8786 the tmpdir must be created.
8787 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8788 dir be in the build tree, instead of $TMPDIR.
8790 2002-09-27 Akim Demaille <akim@epita.fr>
8792 * bin/autoscan.in: Improve the comments.
8793 (&parse_args): Drop obsolete undocumented options.
8794 (&output_kind): Output warnings.
8795 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8801 Reported by Ralf Corsepius.
8802 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8804 2002-09-26 Akim Demaille <akim@epita.fr>
8806 Single suffix rules and seperated dependencies are not portable.
8808 * doc/autoconf.texi (Installation Directory Variables): Update.
8809 (Limitations of Make): Some about `Single Suffix Rules and
8810 Separated Dependencies'.
8811 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8812 (ifnames, autoscan, autom4te): Un-factor into several rules.
8814 2002-09-25 Paul Eggert <eggert@twinsun.com>
8816 * BUGS (Interoperability bugs): New section. Mention libtool
8817 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8819 2002-09-24 Paul Eggert <eggert@twinsun.com>
8821 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8822 make handles suffix-rules differently from GNU make.
8824 * bin/Makefile.am (SUFFIXES, .in): Remove.
8825 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8826 Move the body of the old .in rule here.
8828 2002-09-16 Akim Demaille <akim@epita.fr>
8830 i960 compilers create `b.out' files by default.
8831 Reported by Ralf Corsepius.
8833 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8834 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8836 2002-09-13 Paul Eggert <eggert@twinsun.com>
8838 * doc/autoconf.texi (Particular Headers): Remove obsolete
8839 reference to `struct timezone' in the description of
8840 AC_HEADER_TIME.
8842 2002-09-13 Akim Demaille <akim@epita.fr>
8844 Version 2.54.
8846 * config/config.sub, config/config.guess: Update.
8847 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8848 * Makefile.am: Adjust.
8850 2002-09-13 Akim Demaille <akim@epita.fr>
8852 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8853 reading config.log when the compiler is rejected.
8854 Suggested by Guido Draheim.
8856 2002-09-13 Akim Demaille <akim@epita.fr>
8858 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8859 (chdir_init) might hang when stat'ing mounted directories.
8860 Reported by Vance Shipley.
8862 2002-09-12 Akim Demaille <akim@epita.fr>
8864 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8865 the lists.
8867 2002-09-12 Akim Demaille <akim@epita.fr>
8869 * doc/autoconf.texi (Defining Symbols): Present two different
8870 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8871 difference between 1 argument calls, and 2-3 argument calls.
8873 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8875 * doc/autoconf.texi: Review grammar and punctuation.
8877 2002-09-11 Paul Eggert <eggert@twinsun.com>
8879 * doc/autoconf.texi: Fix minor formatting, spelling, and
8880 grammatical typos.
8881 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8882 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8883 is obsolescent.
8885 2002-09-11 Akim Demaille <akim@epita.fr>
8887 * doc/autoconf.texi (Questions): Rename as...
8888 (FAQ): this.
8889 (Defining Directories): New.
8891 2002-09-09 Akim Demaille <akim@epita.fr>
8893 * doc/autoconf.texi (Making testsuite Scripts): Update.
8894 Suggested by Nishio Futoshi.
8896 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8898 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8899 plain `@' is wanted.
8901 2002-09-09 Akim Demaille <akim@epita.fr>
8903 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8904 `duplicates', since the algorithm was too naive and could keep
8905 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8906 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8907 Reported by Ralf Corsepius.
8908 * tests/torture.at (Configuring subdirectories): Exercise these
8909 cases.
8911 2002-09-09 Akim Demaille <akim@epita.fr>
8913 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8914 looking for a replacement file.
8915 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8916 directory is relative.
8917 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8918 directory definition.
8919 Reported by Andreas Schwab and Jim Meyering.
8921 2002-09-06 Akim Demaille <akim@epita.fr>
8923 * doc/autoconf.texi (Setting Output Variables): Clarify what
8924 precious variables are.
8925 Suggested by Pontus Skoeld.
8927 2002-09-05 Akim Demaille <akim@epita.fr>
8929 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8930 (ifnames, autoscan, autom4te): Since we don't only depend on
8931 configure.ac variables (such as VERSION etc.), but also on prefix
8932 and so forth, depend on Makefile, not configure.ac.
8933 Reported by Alexandre Duret-Lutz.
8934 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8936 2002-09-05 Kevin Ryde <user42@zip.com.au>
8938 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8939 doesn't seem to be confined to ia64, just say "some versions".
8941 2002-09-04 Akim Demaille <akim@epita.fr>
8943 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8944 Automake 1.6c.
8945 * Makefile.am (maintainer-clean-local): Remove.
8946 (MAINTAINERCLEANFILES): Remove COPYING.
8948 2002-09-03 Paul Eggert <eggert@twinsun.com>
8950 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8951 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8952 Brinkmann.
8954 2002-09-03 Akim Demaille <akim@epita.fr>
8956 * configure.ac: Bump to 2.53d.
8957 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8958 as of today, on Automake's team suggestion.
8960 2002-09-03 Akim Demaille <akim@epita.fr>
8962 Version 2.53c.
8964 2002-09-02 Akim Demaille <akim@epita.fr>
8966 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8967 SITE_MACRO_DIR.
8968 * configure.ac: Disable SITE_MACRO_DIR.
8970 2002-09-02 Jim Meyering <meyering@lucent.com>
8972 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8973 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8974 Also, tweak grammar: s/make sure to/be sure to/.
8976 2002-09-02 Paul Eggert <eggert@twinsun.com>
8978 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8979 directory names are generally preferable to physical names.
8981 2002-09-02 Akim Demaille <akim@epita.fr>
8983 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8984 Reported by Raja R. Harinath.
8985 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8986 * bin/autoupdate.in: Use error instead of die.
8988 2002-09-01 Paul Eggert <eggert@twinsun.com>
8990 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8991 ordinary shell concatenation rather than echo+tr+sed command that
8992 runs afoul of a long-line-related sed bug in Solaris 8.
8994 * bin/autoheader.in (parse_args): --warning -> --warnings.
8996 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8997 stdout, as traditional "ls" does.
8998 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8999 _AC_COMPILER_EXEEXT_O): Likewise.
9000 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9002 * bin/autoconf.as: Add --prepend-include option. This patch was
9003 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9004 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9006 * bin/autoconf.in, configure: Regenerate.
9008 * doc/autoconf.texi (Special Shell Variables): Mention
9009 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9011 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9012 MAILPATH and set PS1, PS2, PS4 to default values, to work
9013 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9014 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9015 the Autoconf documentation specifies; fall back to "unset" only if
9016 this fails. Use a shell for-loop for this rather than an m4 loop,
9017 to shorten the output script.
9019 2002-08-30 Paul Eggert <eggert@twinsun.com>
9021 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9022 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9023 for the CDPATH problem. Document PWD.
9024 (Limitations of Builtins): Document the problem that "cd $foo" and
9025 "ls $foo" may refer to different directories in shells conforming
9026 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9027 example, since the old example is now out of date.
9029 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9030 FOO" and "ls FOO" talk about different directories; this catches
9031 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9032 spaghetti.
9034 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9035 of rolling our own unset.
9036 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9037 in practice we needn't worry about CDPATH if unset doesn't work.
9039 * Makefile.in, aclocal.m4, bin/Makefile.in,
9040 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9041 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9042 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9043 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9044 tests/Makefile.in: Regenerate with Automake 1.6.3.
9046 * config/config.guess, config/config.sub, config/mkinstalldirs:
9047 Update.
9049 * configure: Regenerate with self.
9051 2002-08-30 Kevin Ryde <user42@zip.com.au>
9053 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9054 default output.
9056 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9058 * bin/autom4te.in (Request::load): Correctly test for "do" read
9059 failure.
9061 2002-08-29 Akim Demaille <akim@epita.fr>
9063 * lib/Autom4te/General.pm (&xqx): New.
9064 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9065 hand, which is not portable.
9066 (&error): New.
9067 * bin/autom4te.in: Use them.
9068 Use &error instead of die.
9069 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9070 Adjust.
9072 2002-08-17 Paul Eggert <eggert@twinsun.com>
9074 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9075 default list of compilers to try, since it was long ago superseded
9076 by the ksh fc builtin. Suggested by Steven G. Johnson.
9078 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9080 * doc/autoconf.texi (Invoking autom4te): End the option table,
9081 fixing a bug introduced by the previous patch.
9082 (Limitations of Make): Add a 'target lookup' subentry in the
9083 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9085 2002-07-29 Mark D. Roth <roth@feep.net>
9087 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9088 options and use $AUTOM4TE_PATH.
9089 * doc/autoconf.texi: Remove documentation of autom4te
9090 --include-envvar and --site-macro-subdir options and document
9091 use of $AUTOM4TE_PATH.
9092 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9093 arguments from each language section.
9095 2002-07-29 Paul Eggert <eggert@twinsun.com>
9097 * doc/install.texi: Include copyright symbol in copyright notice.
9099 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9100 Replace with:
9101 (AM_MAKEINFOFLAGS): New macro.
9102 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9103 * Makefile.am (INSTALL): Use the new macros.
9104 Use -o rather than --output, since "missing" does not grok --output.
9106 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9108 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9109 comments do not always work. Never trust the exit status of
9110 `make -k'.
9112 2002-07-24 Kevin Ryde <user42@zip.com.au>
9114 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9115 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9117 2002-07-23 Paul Eggert <eggert@twinsun.com>
9119 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9120 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9121 apparently treats PATH="nonexistent" as if it contained ".".
9122 Bug reported by Stefan `Sec' Zehl.
9124 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9126 * doc/autoconf.texi (Limitations of Make): Mention the special
9127 handling of the obj/ directory by BSD make.
9129 2002-07-20 Kevin Ryde <user42@zip.com.au>
9131 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
9132 backslashes.
9134 2002-07-19 Akim Demaille <akim@epita.fr>
9136 * doc/autoconf.texi (Function Portability): `exit'.
9137 (Programming in M4sh): Ethymology of M4sh.
9139 2002-07-19 Akim Demaille <akim@epita.fr>
9141 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
9143 2002-07-18 Akim Demaille <akim@epita.fr>
9145 Version 2.53b.
9147 2002-07-18 Akim Demaille <akim@epita.fr>
9149 * config/config.guess, config/config.sub: Update.
9151 2002-07-18 Akim Demaille <akim@epita.fr>
9153 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
9154 Automake's parts.
9156 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
9157 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
9158 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
9160 2002-07-18 Akim Demaille <akim@epita.fr>,
9161 Alexandre Duret-Lutz <duret_g@epita.fr>
9163 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
9164 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

9169 description of the tarname default.
9171 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
9173 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
9174 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
9175 latter was not run.
9177 2002-07-17 Akim Demaille <akim@epita.fr>
9179 * lib/Autom4te/General.pm (find_file): Browse the directories in
9180 the order they are given.
9182 2002-07-17 Akim Demaille <akim@epita.fr>
9184 * tests/wrapsh.as, tests/wrappl.as: Merge into...
9185 * tests/wrapper.as: this.
9186 * tests/Makefile.am, configure.ac: Adjust.
9188 2002-07-17 Mark D. Roth <roth@feep.net>
9190 * configure.ac: Add --enable-site-macro-dir option.
9191 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
9192 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
9193 --site-macro-subdir options.
9194 * bin/autoconf.in: Add --prepend-include option.
9195 * bin/autoheader.in: Add --prepend-include option.
9196 * bin/autoreconf.in: Add --prepend-include option.

9198 * bin/autoupdate.in: Add --prepend-include option.
9199 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
9200 macro directory, remove note that include path directories are
9201 used in reverse order, and document --prepend-include option.
9202 * lib/autom4te.in: Use --prepend-include instead of --include.
9203 * tests/wrapsh.in: Use --prepend-include instead of --include.
9205 2002-07-17 Akim Demaille <akim@epita.fr>
9207 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
9208 tarnames.
9209 * doc/autoconf.texi (Initializing configure): Adjust.
9211 2002-07-17 Akim Demaille <akim@epita.fr>
9213 * lib/autoconf/functions.m4 (AC_FUNC_REALLOC, _AC_FUNC_REALLOC)
9214 (_AC_FUNC_MALLOC): New.

9248 2002-06-27 Paul Eggert <eggert@twinsun.com>
9250 * config/install-sh: Quote $src. Prefer || to test's -o option,
9251 as per "Limitations of Builtins".
9252 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9253 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9255 * tests/mktests.sh: Use grep instead of fgrep, as per
9256 "Limitations of Builtins".

9283 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9285 * bin/autom4te.in ($cache): Don't define using `$me', the name
9286 of the cache should not depend on the name under which autom4te
9287 was installed.
9289 2002-06-07 Akim Demaille <akim@epita.fr>
9291 * tests/tools.at (autoconf: forbidden tokens, basic)

9293 words in autom4te.in.
9295 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9297 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9298 _AC_LANG_PROGRAM_C_F77_HOOKS.
9300 2002-06-07 Akim Demaille <akim@epita.fr>
9302 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,

9306 AC_FUNC_FNMATCH_GNU.
9308 2002-06-07 Akim Demaille <akim@epita.fr>
9310 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the

9313 2002-06-07 Akim Demaille <akim@epita.fr>
9315 * bin/autom4te.in (warn_forbidden): When rejecting a token,

9317 Suggested by Adam J. Richter.
9319 2002-06-07 Akim Demaille <akim@epita.fr>

9324 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

9378 version of Autoconf that is discussed.
9380 2002-05-22 Paul Eggert <eggert@twinsun.com>
9382 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9383 from the default list of compilers to try. Suggested by
9384 Kate Hedstrom.
9385 * NEWS: Document the above.
9386 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9388 2002-05-17 Paul Eggert <eggert@twinsun.com>
9390 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9391 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9392 This improves on an earlier suggestion by H. Peter Anvin.
9394 2002-05-16 Paul Eggert <eggert@twinsun.com>
9396 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9397 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9398 Both macros now accept an optional source-dir arg.
9399 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9401 * NEWS: Document this.
9402 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9404 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9405 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9406 not for GNU extensions; this undoes part of the 2000-11-03 change,
9407 reverting to 2.13-compatible behavior.
9408 Add new optional argument DIR.
9409 (AC_FUNC_FNMATCH_GNU): New macro.
9411 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9413 2002-05-08 Paul Eggert <eggert@twinsun.com>
9415 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9416 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9417 and it causes a 'test' syntax error if it fails.
9418 Bug reported by Stephen Gildea.
9420 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9421 If prototypes are supported, use them to check this at compile-time,
9422 instead of trying to check it at run-time. If we must do a run-time
9423 check, assume that setvbuf is standard when cross-compiling, as
9424 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9425 Bug reported by Paul D. Smith.
9427 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9428 argument specifying location of getloadavg.c. This removes a
9429 FIXME. This idea was taken from Jim Meyering's implementation in
9430 textutils.
9431 * doc/autoconf.texi (Particular Functions): Document this.
9432 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9433 that's what the code does; this fixes a bug reported by
9434 Paul D. Smith.
9436 2002-05-03 Akim Demaille <akim@epita.fr>
9438 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9439 autopoint instead of gettextize.
9440 ($uses_alocal): Rename as...
9441 ($uses_aclocal): this.
9442 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9443 Suggested by Bruno Haible.
9445 2002-05-03 Akim Demaille <akim@epita.fr>
9447 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9449 2002-04-29 Paul Eggert <eggert@twinsun.com>
9451 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9452 files to be 1 second older; just set them to be the same time.
9453 Also, sleep 1 second after the first aclocal, to work around
9454 problems with sub-second time stamps on the input files.
9456 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9458 * doc/autoconf.texi: Mention "set -e -x" lossage
9459 under node "Limitations of Builtins".
9461 2002-04-29 Akim Demaille <akim@epita.fr>
9463 * doc/install.texi: Better wording for setting variables when
9464 running configure.
9465 From Christian Cornelssen.
9467 2002-04-29 Akim Demaille <akim@epita.fr>
9469 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9470 of lack of $LINENO support, then the test will compare the $LINENO
9471 in testsuite vs. the lineno in the test file. This is wrong, of
9472 course.
9473 Be sure to protect it.
9474 Reported by Patrick Welche.
9476 2002-04-25 Akim Demaille <akim@epita.fr>
9478 * doc/autoconf.texi (Obsolete Macros): Typo.
9479 Reported by Vladimir Volovich.
9481 2002-04-25 Akim Demaille <akim@epita.fr>
9483 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9484 than some of the input files, hence, on the second run of aclocal,
9485 if some of its input are younger, make them older.
9486 Suggested by Paul Eggert.
9488 2002-04-25 Akim Demaille <akim@epita.fr>
9490 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9491 Thanks to Paul Eggert.
9493 2002-04-25 Akim Demaille <akim@epita.fr>
9495 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9496 and ac_subst_vars be sh variables containing the list of
9497 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9498 DEFAULT diversion.
9499 (_AC_INIT_PREPARE): Use them to log them.
9500 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9501 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9502 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9503 _AC_SUBST_FILES and _AC_SUBST_VARS.
9504 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9506 2002-04-24 Akim Demaille <akim@epita.fr>
9508 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9509 autoheader, so that automake does not complain about a missing
9510 config.h.in that was to be created.
9512 2002-04-23 Akim Demaille <akim@epita.fr>
9514 * bin/autoheader.in (parse_args): --warning takes an argument.
9515 Fixes PR/220.

9566 * doc/autoconf.texi: Follow the outline suggested in the GNU
9567 Sample Texts sections of the Texinfo 4.2 manual. Most
9568 importantly, this makes sure that the copyright notices appear in
9569 all output formats. You probably need Texinfo 4.2 to generate
9570 the manual now.

9626 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9675 Don't use the KILL diversion, as it kills spurious output, which
9676 results in failures being hidden.

9710 (AC_C_CONST): Same.
9711 (AC_C_INLINE): Same.
9712 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9713 * doc/autoconf.texi, NEWS: Document.
9714 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9715 AC_C_CROSS.
9717 2002-04-02 Akim Demaille <akim@epita.fr>
9719 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9720 _AS_MKDIR_P_PREPARE.
9722 2002-03-28 Kevin Ryde <user42@zip.com.au>
9724 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9725 to avoid versions of HP C which don't allow that.
9727 2002-03-27 Paul Eggert <eggert@twinsun.com>
9729 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9730 (AS_SHELL_SANITIZE): Invoke it.
9731 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9733 2002-03-26 Akim Demaille <akim@epita.fr>
9735 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9737 2002-03-26 Akim Demaille <akim@epita.fr>
9739 * doc/autoconf.texi (Introduction): The GNATS base moved.
9741 2002-03-25 Paul Eggert <eggert@twinsun.com>
9743 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9744 as POSIX requires, as it doesn't work with Zsh.
9745 * doc/autoconf.texi (Assignments): Document the problem.
9747 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9749 * doc/autoconf.texi (Limitations of Make): Mention more issue
9750 about VPATH, overriding of macros in sub-makes, and handling of
9751 SHELL.
9753 2002-03-21 Paul Eggert <eggert@twinsun.com>
9755 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9756 problem with here-document buffer boundaries.
9758 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9759 when reinvoking the shell, to work around problems with installers
9760 who put strange things like "cd" commands in their environments.
9762 2002-03-19 Akim Demaille <akim@epita.fr>
9764 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9765 From Aaron Ucko.
9767 2002-03-19 Akim Demaille <akim@epita.fr>
9769 * bin/autoscan.in (scan_file): Specify the location in `&used'
9770 invocations.
9771 From Nicolas Joly.
9773 2002-03-19 Akim Demaille <akim@epita.fr>
9775 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9776 From Nishio Futoshi.
9778 2002-03-19 Akim Demaille <akim@epita.fr>
9780 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9782 2002-03-18 Paul Eggert <eggert@twinsun.com>
9784 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9785 (Limitations of Usual Tools): Add mkdir section.
9787 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9788 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9789 back on AS_DIRNAME to compute prefixes otherwise; this is
9790 roughly what mkinstalldirs does. That way, we need not have
9791 our own filename disassembler. The old disassembler did not
9792 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9794 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9795 Create at_test_all by a series of assignments,
9796 not by a single assignment of a long string. The latter causes ksh
9797 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9798 presumably because of a buffer overrun.
9800 2002-03-14 Paul Eggert <eggert@twinsun.com>
9802 * lib/autotest/general.m4 (at_times_skip):
9803 Renamed from at_times. Now a boolean.
9804 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9805 says 'times: not found'.
9807 2002-03-14 Akim Demaille <akim@epita.fr>
9809 * bin/autoreconf.in (&study_gettextize): New.
9810 (&autoreconf): Handle newest gettextize.
9811 Rerun aclocal if needed.
9812 Suggested by Andreas Schwab.
9814 2002-03-13 Akim Demaille <akim@epita.fr>
9816 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9818 2002-03-13 Akim Demaille <akim@epita.fr>

9821 Add information about stdint.h and inttypes.h from Paul Eggert.
9823 2002-03-13 Akim Demaille <akim@epita.fr>
9825 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9826 -p'.
9827 From Bob Proulx.
9829 2002-03-12 Akim Demaille <akim@epita.fr>
9831 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9832 m4_require.
9834 2002-03-11 Andreas Schwab <schwab@suse.de>
9836 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9837 does not do it if --with-lispdir is given.
9839 2002-03-08 Akim Demaille <akim@epita.fr>
9841 Version 2.53.
9843 2002-03-08 Akim Demaille <akim@epita.fr>
9845 * doc/autoconf.texi (Subdirectories): Clarify that the
9846 subdirectory should exist.
9848 2002-03-08 Akim Demaille <akim@epita.fr>
9850 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9852 2002-03-08 Akim Demaille <akim@epita.fr>
9854 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9855 aliases the actual variables, and modifications of the former
9856 affect the latter.
9858 2002-03-08 Akim Demaille <akim@epita.fr>
9860 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9861 because of C-c: have m4 output in tmp files, then mv them.
9863 2002-03-08 Akim Demaille <akim@epita.fr>
9865 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9866 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9867 * bin/ifnames.in: Copyright update.
9869 2002-03-08 Akim Demaille <akim@epita.fr>
9871 * doc/autoconf.texi (Invoking autom4te): New.
9873 2002-03-05 Akim Demaille <akim@epita.fr>
9875 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9876 Kevin Ryde.
9878 2002-03-05 Akim Demaille <akim@epita.fr>
9880 Version 2.52i.
9882 2002-03-04 Akim Demaille <akim@epita.fr>
9884 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9885 * lib/autoconf/general.m4 (AC_INIT): More informative error
9886 message for LIBOBJ.
9888 2002-03-04 Akim Demaille <akim@epita.fr>
9890 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9891 parallel builds.
9893 2002-03-04 Akim Demaille <akim@epita.fr>
9895 * doc/autoconf.texi (Transforming Names): Equality between target
9896 and host is irrelevant.
9897 (Specifying Names, Canonicalizing): Remove all references to the
9898 backward compatibility hooks. Rather, collect them all into...
9899 (Hosts and Cross-Compilation): this new section.
9900 * doc/install.texi (System Type): Ditto.
9901 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9902 that `--host' implies cross-compilation.
9904 2002-03-04 Akim Demaille <akim@epita.fr>
9906 * doc/autoconf.texi (Evaluation Macros): New.
9907 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9908 useless.
9909 (_m4_foreach): Define the variant with immediate evaluation so
9910 that it contains exactly the items, not an expression which
9911 evaluation is the current item.
9912 (m4_re_string, m4_re_word): Don't over quote them.
9914 2002-03-04 Akim Demaille <akim@epita.fr>
9916 Instead of having stacking `shift's evaluated at the end, let
9917 `foreach' loops immediately evaluate them.
9919 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9920 $*. This is the n-th time I change my mind, but hopefully this is
9921 the last...
9922 (m4_lquote): New.
9923 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9924 efficient.
9925 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9926 it was only a hack for m4_text_wrap.
9927 (m4_car2): Remove, replaced by...
9928 (m4_cdr): New.
9929 (_m4_foreach): Adjust.
9930 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9931 m4_bpatsubst for clarification.
9933 2002-03-04 Akim Demaille <akim@epita.fr>
9935 * doc/autoconf.texi (Changequote is Evil): New.
9937 2002-03-03 Kevin Ryde <user42@zip.com.au>
9939 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9940 on old systems like SunOS.
9942 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9944 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9945 lib/autoconf/functions.m4, lib/autoconf/general.m4,
9946 lib/autoconf/headers.m4, lib/autoconf/lang.m4,

9962 From Akinori Musha.
9964 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9966 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9967 translate \r\n to \n.
9969 2002-02-07 Akim Demaille <akim@epita.fr>
9971 Version 2.52h.
9973 2002-02-07 Akim Demaille <akim@epita.fr>
9975 Fix Autoconf PR/209.
9976 Also reported by Frank Denis.
9978 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9980 2002-02-07 Akim Demaille <akim@epita.fr>
9982 Fix Autoconf PR/207:
9983 AC_PREFIX_PROGRAM fails with dashed program names
9985 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9986 variable when looking for the prefix program.
9987 Now it also works for shell variables.
9989 2002-02-07 Akim Demaille <akim@epita.fr>

9992 case/esac.

9996 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9997 case/esac, some shells don't support it.
9998 Reported by Zack Weinberg.
9999 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10001 2002-02-06 Akim Demaille <akim@epita.fr>
10003 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10004 sure not to introduce newlines in at_groups.
10005 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10007 2002-02-06 Akim Demaille <akim@epita.fr>
10009 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10010 is not available.
10012 2002-02-05 Paul Eggert <eggert@twinsun.com>
10014 * doc/autoconf.texi (Specific Compiler Characteristics):
10015 Describe HP-UX cc bug workaround more accurately.
10016 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10017 not unsigned long.
10018 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10019 cross-compilers, too. This undoes some of the most recent change
10020 to this file.
10022 2002-02-05 Akim Demaille <akim@epita.fr>
10024 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10025 to make sure they are up to date when `check' is run.
10027 2002-02-05 Akim Demaille <akim@epita.fr>
10029 * doc/autoconf.texi (Making testsuite Scripts): Document
10030 package.m4.
10032 2002-02-05 Akim Demaille <akim@epita.fr>
10034 * lib/freeze.mk: New.
10036 2002-02-05 Akim Demaille <akim@epita.fr>
10038 Implement `autom4te --freeze'.
10040 * bin/autom4te.in (&freeze): New.
10041 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10042 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10044 2002-02-05 Akim Demaille <akim@epita.fr>
10046 * bin/autom4te.in (&parse_args): Implement `frozen files are
10047 optional are the sum of the previous files on the command line'.
10048 Also, pass `--reload-state=' on them, so...
10049 (handle_m4): don't.
10050 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10051 (M4sh): Rely on M4sugar.
10052 (Autotest, M4sh, M4sugar): Use frozen files.
10054 2002-01-31 Akim Demaille <akim@epita.fr>
10056 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10057 * doc/autoconf.texi (Initializing configure): Adjust.
10059 2002-01-30 Akim Demaille <akim@epita.fr>
10061 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10062 alphanumeric to `-' instead of `_'.
10064 2002-01-30 Akim Demaille <akim@epita.fr>
10066 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10067 for plain code, the other for cross-compilation code. The latter
10068 is now run with GCC only.
10069 * doc/autoconf.texi (Compilers and Preprocessors): New.
10071 2002-01-30 Akim Demaille <akim@epita.fr>
10073 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10074 values.
10075 * doc/autoconf.texi (Initializing configure): Explain how to
10076 change AC_INIT default values.
10078 2002-01-29 Akim Demaille <akim@epita.fr>
10080 * tests/torture.at (Configuring subdirectories): Use configure.in,
10081 so that aclocal 1.4 works.
10082 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10084 2002-01-28 Akim Demaille <akim@epita.fr>
10086 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10087 needs an argument.
10089 2002-01-28 Akim Demaille <akim@epita.fr>
10091 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10092 AUTOTEST_PATH *after* it was set.
10093 Don't put `.' in the PATH: the user should be precise and `./' if
10094 needed. In addition, given that the test suite does some `cd', if
10095 `.' is in the path, the `tested programs' sections will report
10096 programs found in the test suite's directory, while during the
10097 tests (performed in their own directory), these programs are no
10098 longer visible. In other words, the results is confusing and
10099 useless.
10100 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10102 2002-01-24 Akim Demaille <akim@epita.fr>
10104 Version 2.52g.
10106 2002-01-24 Akim Demaille <akim@epita.fr>

10109 * doc/autoconf.texi: Finally add Akim as an author.
10111 2002-01-24 Akim Demaille <akim@epita.fr>
10113 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10114 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10115 Bourne. Use /bin/sh.
10116 From Andreas Buening.
10118 2002-01-24 Akim Demaille <akim@epita.fr>
10120 * config/config.guess, config/config.sub, config/texinfo.tex:

10129 * config/strip.m4: Remove, to ease sync'ing with any version of
10130 Automake.
10132 2002-01-24 Akim Demaille <akim@epita.fr>
10134 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10135 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10136 Reported by Geir Ove Myhr.
10138 2002-01-21 Akim Demaille <akim@epita.fr>
10140 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10142 2002-01-21 Akim Demaille <akim@epita.fr>
10144 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10145 message on invalid options.
10146 * bin/autom4te.in (parse_args): Don't use
10147 Autoconf::General::getopt with non valid options.
10149 2002-01-17 Jim Meyering <meyering@lucent.com>
10151 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10152 $ac_cv_exeext so we don't use an old, invalid, cached value.
10154 2002-01-11 Akim Demaille <akim@epita.fr>
10156 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10157 Meyering.

10159 limitation.

10163 2002-01-06 Akim Demaille <akim@epita.fr>
10165 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10166 package.m4, since is really depends upon configure.ac, not
10167 configure.
10168 * doc/autoconf.texi (testsuite Scripts): Adjust.
10169 * tests/Makefile.am (package.m4): New.
10170 EXTRA_DIST it since its a source.
10172 2002-01-06 Akim Demaille <akim@epita.fr>
10174 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10175 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10176 and PACKAGE_BUGREPORT from here...
10177 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10178 arguments.
10179 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10180 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10181 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10182 * tests/tools.at (autoheader): Adjust.
10183 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10185 2002-01-06 Akim Demaille <akim@epita.fr>

10189 2002-01-03 Akim Demaille <akim@epita.fr>
10191 * doc/autoconf.texi (Output): Improved wording regarding use of
10192 AC_OUTPUT.
10193 From Olly Betts.
10195 2001-12-18 Kevin Ryde <user42@zip.com.au>
10197 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10198 sometimes needing writable input.
10200 2001-12-17 Jim Meyering <meyering@lucent.com>
10202 * doc/autoconf.texi (New Macros): Tweak wording.
10204 2001-12-14 Akim Demaille <akim@epita.fr>
10206 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10207 trailing files, don't apply `-rf' to files which might not be
10208 created by configure (core, core.*, and *.core), but just `rm -f'.
10209 Suggested by Jonathan Kamens.

10213 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10215 2001-12-14 Akim Demaille <akim@epita.fr>
10217 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10219 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10221 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10222 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10223 abs_srcdir, top_srcpath to abs_top_srcdir.
10224 (_AC_OUTPUT_FILES): Adjust.
10225 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10226 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10227 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10229 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10231 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10232 C/Fortran linking on HP/UX, by extracting the Fortran library
10233 search path from the LPATH line in the $F77 -v output.
10235 2001-12-12 Kevin Ryde <user42@zip.com.au>
10237 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10238 forbidden file descriptors table.
10240 2001-11-26 Akim Demaille <akim@epita.fr>
10242 * bin/autoscan.in (%c_keywords): Build it at top level.
10243 Map to 1 in order to simplify its uses.
10245 2001-11-26 Akim Demaille <akim@epita.fr>
10247 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10248 Remove $filepath, useless.
10249 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10250 variables, they are really part of the tokens.
10251 Split the input line on spaces and then look for tokens.
10252 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10253 because of `lex$U.$(OBJEXT)'.
10254 (&scan_files): Use "@list" instead of join.
10255 * doc/Makefile.am (CLEANFILES): Add *.fns.
10257 2001-11-26 Akim Demaille <akim@epita.fr>
10259 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10260 Remove, replaced by...
10261 * tests/wrappl.in: Be common for all the Perl executables.
10262 In particular autoscan and autoheader want -I.
10263 * configure.ac: Adjust.
10264 * lib/autoscan/headers: errno.h is portable.
10266 2001-11-26 Akim Demaille <akim@epita.fr>
10268 * bin/autoscan.in (used): New.
10269 Use it.
10271 2001-11-26 Akim Demaille <akim@epita.fr>
10273 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10274 directives.
10275 (&scan_sh_file): Remove a duplicate pattern.
10276 (&check_configure_ac): Use long options.
10277 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10279 2001-11-26 Akim Demaille <akim@epita.fr>
10281 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10282 Before, having a line containing the opening of a multi line
10283 comment made the whole line be ignored.
10285 2001-11-26 Akim Demaille <akim@epita.fr>
10287 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10288 (testsuite Scripts): Be one of its subsection.
10289 (Autotest Logs): New.
10291 2001-11-26 Akim Demaille <akim@epita.fr>
10293 Test groups are now run two directories deeper.
10295 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10296 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10297 at_top_builddir.
10298 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10299 top_srcdir, builddir and top_builddir.
10300 Use `at_*dir' relatively to the directory containing the
10301 suite, use `*dir' when relatively to the current group dir.
10303 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10305 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10306 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10307 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10308 spelling errors.
10310 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10312 * doc/autoconf.texi (Using System Type): Add an example of `case
10313 $host' usage so people quit using `case $target' everywhere.
10315 2001-11-22 Akim Demaille <akim@epita.fr>
10317 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10318 spotted by Jim Meyering.
10320 2001-11-16 Paul Eggert <eggert@twinsun.com>
10322 This patch implements a `long double' suggestion by Oliver Kiddle.
10324 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10325 static, to catch errors if the value isn't known at compile-time
10326 and the compiler supports dynamic arrays. Change its name from
10327 `_array_' to `test_array' to avoid potential name clashes.
10328 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10329 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10330 better than double. Catch a bug in GCC 2.95.2 x86.
10331 * doc/autoconf.texi (C Compiler): Document the above.
10332 * NEWS: Likewise.
10334 2001-11-13 Akim Demaille <akim@epita.fr>
10336 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10337 hand.
10338 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10340 2001-11-13 Akim Demaille <akim@epita.fr>
10342 * lib/autotest/general.m4 (AT_INIT): After having run the test
10343 group, go back to the initial directory, not to at_suite_dir.
10345 2001-11-13 Akim Demaille <akim@epita.fr>
10347 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10348 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10349 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10350 option.
10351 (AT_CHECK_CONFIGURE): Use absolute paths.
10352 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10353 The problem is still the old one: there is no means in M4 (that I
10354 know about) to create a defining macro, because there is no means
10355 to create `$1' etc., therefore, the defining macro ``swallows''
10356 all the arguments meant to the defined macro.
10358 2001-11-13 Akim Demaille <akim@epita.fr>
10360 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10361 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10362 configure.ac.
10363 * tests/aclocal.m4: Remove, as it is no longer used.
10365 2001-11-13 Akim Demaille <akim@epita.fr>
10367 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10368 variable names when referring to a single test group, or to
10369 `suite' when referring to the whole test suite.
10370 `at_last_test' is removed: m4 compute at_format itself.
10371 (at_stdout, at_stder1, at_stderr): New variables.
10372 (AT_CHECK): Use them.
10374 2001-11-13 Akim Demaille <akim@epita.fr>
10376 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10377 in PATH.
10378 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10379 Do it as soon as a test fails, don't wait till the end of the test
10380 suite.
10381 Don't remove $as_me.[0-9]*, since these files no longer exist.
10383 2001-11-13 Akim Demaille <akim@epita.fr>
10385 * tests/tools.at: Use absolute paths, since we are no longer run
10386 in place.
10388 2001-11-13 Akim Demaille <akim@epita.fr>
10390 Now that tests are running in their own private dir, there is no
10391 need to list the files to remove at the end of tests groups.
10393 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10394 (AT_data_files, at_data_files): Remove.
10395 (AT_CLEANUP, AT_DATA): Simplify.
10396 (AT_INIT): Adjust.
10397 Remove the group dir if !debug && !failed.
10398 * tests/atspecific.m4: Adjust.
10400 2001-11-13 Akim Demaille <akim@epita.fr>
10402 Start a new layout for Autotest: `testsuite' creates
10403 `testsuite.dir' in which the at-check-line etc. files are to be
10404 found, and `testsuite.dir/003' where the test group 3 is run.
10406 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10407 at_check_line_file, at_format, at_test_normalized, at_group_dir
10408 are new variables.
10409 Create the directories.
10410 Use absolute paths for at- files.
10411 (AT_CHECK): Adjust.
10413 2001-11-11 Michael Matz <matz@kde.org>
10415 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10416 (m4_car2): New.
10417 (m4_car): Properly quote arguments.
10419 2001-11-13 Akim Demaille <akim@epita.fr>
10421 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10422 with stricter rules on LIBOBJS.
10424 2001-11-12 Paul Eggert <eggert@twinsun.com>
10426 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10427 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10428 __PROTOTYPES too.
10430 2001-11-12 Akim Demaille <akim@epita.fr>
10432 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10434 2001-11-12 Akim Demaille <akim@epita.fr>
10436 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10437 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10438 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10439 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10440 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10441 specify to what the macro should be defined (typically to 1).
10443 2001-11-12 Akim Demaille <akim@epita.fr>
10445 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10446 From Jim Meyering.
10448 2001-11-12 Akim Demaille <akim@epita.fr>
10450 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10451 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10452 definition used by Automake where LEX is +/- "${missing} lex" and
10453 `missing' itself contains variables.
10455 2001-11-12 Akim Demaille <akim@epita.fr>
10457 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10458 Now that M4sh pushes BODY, the comments were output at the end of
10459 the test suites.
10461 2001-11-08 Akim Demaille <akim@epita.fr>
10463 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10464 that we can trace macros from aclocal.m4.
10465 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10466 obsoleted, and redirect to the former anyway.
10467 Reported by Ralf Corsepius.
10469 2001-11-08 Akim Demaille <akim@epita.fr>
10471 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10472 processed only if present.
10473 * tests/torture.at (Configuring subdirectories): Use autoreconf
10474 instead of successive calls to autoconf.
10475 Add a nonexistent subdirectory to exercise the patch above.
10476 Reported by Ralf Corsepius.
10478 2001-11-08 Kevin Ryde <user42@zip.com.au>
10480 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10481 doesn't accept .S files.
10483 2001-11-07 Akim Demaille <akim@epita.fr>
10485 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10486 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10487 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10488 * bin/autom4te.in (warn_forbidden): New.
10489 (handle_output): Use it.
10490 Read m4_pattern_forbid with messages.
10492 2001-11-05 Akim Demaille <akim@epita.fr>
10494 * bin/autom4te.in (--normalize): Remove.
10495 * lib/autom4te.in: Adjust.
10497 2001-11-05 Akim Demaille <akim@epita.fr>
10499 * tests/Makefile.am (testsuite): Rename this target as...
10500 ($(TESTSUITE)): this.
10501 From Nicolas Joly.
10503 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10505 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10506 the --prefix option, also remove it's argument.
10508 2001-11-05 Akim Demaille <akim@epita.fr>
10510 * doc/autoconf.texi (testsuite Invocation): Update.
10511 (Writing testsuite.at): Update.
10513 2001-11-03 Akim Demaille <akim@epita.fr>
10515 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10517 2001-11-03 Akim Demaille <akim@epita.fr>
10519 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10520 (&file_name_is_absolute): New, wrappers around routines from
10521 File::Spec.
10522 Use and export them.
10523 (&find_configure_ac): Optionally take a directory where to look at.
10524 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10525 the arguments.
10526 Default @ARGV to `.', not find_configure_ac.
10527 (&autoreconf): Argument is a directory.
10528 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10529 * doc/autoconf.texi (autoreconf Invocation): Update.
10531 2001-11-03 Akim Demaille <akim@epita.fr>
10533 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10534 (@export_forward_subs): New.
10535 Add basename, dirname, and fileparse.
10536 (@EXPORT): Adjust.
10537 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10538 Don't look for aclocal flags if we already know aclocal is not
10539 used.
10540 Move aclocal.m4t only if it exists.
10541 Reported by Ezra Peisach.
10543 2001-11-03 Akim Demaille <akim@epita.fr>
10545 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10546 passed on command line, defaulting to ./configure.ac if present.
10547 (&maybe_autoreconf, File::Find): Remove, unused.
10548 (&autoreconf): If autoconf is not used, don't try to trace.
10550 2001-11-02 Akim Demaille <akim@epita.fr>
10552 * configure.ac: Bump to 2.52g.
10554 2001-11-02 Akim Demaille <akim@epita.fr>
10556 Version 2.52f.
10558 2001-11-02 Akim Demaille <akim@epita.fr>
10560 * config/config.guess, config/config.sub, doc/standards.texi:
10561 * config/lispdir.m4: Update from masters.
10562 * configure.ac: Bump to 2.52f.
10564 2001-11-02 Akim Demaille <akim@epita.fr>
10566 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10567 Don't run aclocal when aclocal.m4 is not from aclocal.
10568 From Ezra Peisach.
10569 Don't run libtoolize and gettextize if --install is not given.
10571 2001-11-01 Paul Eggert <eggert@twinsun.com>
10573 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10574 be invoked before _AS_LINENO_PREPARE.
10575 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10576 than character ranges.
10578 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10579 invoking AS_BASENAME. Set the locale variables to 'C' if
10580 possible, as POSIX requires this to get the traditional
10581 behavior.
10582 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10584 2001-10-31 Paul Eggert <eggert@twinsun.com>
10586 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10587 with {}, as that triggers a bug in Bash 2.05.
10589 (_AS_LINENO_PREPARE): Use Sed rather than
10590 Awk. Fix the sed prepass to work even if there are multiple
10591 instances of $LINENO on the same line. Do not substitute for
10592 other variables like $LINENOT. Do not check file dates; such a
10593 check is unreliable on sufficiently fast machines, and removing
10594 the check makes the code simpler and more reliable. Check for
10595 output and chmod failures.
10597 * doc/autoconf.texi (Special Shell Variables): Document
10598 the above.
10600 2001-10-31 Akim Demaille <akim@epita.fr>
10602 * tests/Makefile.am (atconfig): Remove this target, Automake
10603 handles it now.
10605 2001-10-31 Akim Demaille <akim@epita.fr>
10607 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10608 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10609 provided, while it is optional.
10610 * configure.ac: Adjust.
10612 2001-10-26 Paul Eggert <eggert@twinsun.com>
10614 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10615 lib/Autom4te/Struct.pm:
10616 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10617 with 5.005_02.
10619 * doc/autoconf.texi (Special Shell Variables): Document some
10620 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10622 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10623 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10624 eval $LINENO is not portable in practice.
10626 2001-10-24 Akim Demaille <akim@epita.fr>
10628 * lib/Autom4te/General.pm (backname): New.
10630 2001-10-24 Akim Demaille <akim@epita.fr>
10632 * m4/: Remove, merged into...
10633 * config/: here.
10635 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10637 * doc/autoconf.texi (Shellology): Mention the problems with bash
10638 2.05's use of ANSI quoting in its `set' builtin.
10640 2001-10-22 Paul Eggert <eggert@twinsun.com>
10642 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10643 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10644 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10645 POSIX decided to standardize on the int flavor of strerror_r.
10646 Always do char* test, as there's no reason not to.
10647 Assign to a char* var, to catch strerror_r that returns int*.
10649 * doc/autoconf.texi (Particular Functions):
10650 Document the above changes. Also, document the fact that
10651 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10653 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10655 2001-10-20 Akim Demaille <akim@epita.fr>
10657 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10658 the executable was missing from the log.
10660 2001-10-20 Akim Demaille <akim@epita.fr>
10662 * lib/Autom4te/General.pm (&update_file): If destination is
10663 unchanged, remove the source.
10664 (&up_to_date_p): Don't be verbose, be debug.
10665 * bin/autoreconf.in: No longer support --m4dir.
10666 (&autoreconf): Display the full path of the configure.ac we are
10667 studying.
10668 Trace it only once.
10669 Be sure to honor --force with gettextize.
10670 Always run aclocal.
10671 * doc/autoconf.texi: Adjust.
10673 2001-10-20 Akim Demaille <akim@epita.fr>
10675 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10676 Remove, dead.
10677 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10678 `intl' is already present, as it refuses unless --force.

10957 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

11128 * lib/autoconf/programs.m4: Use extensions listed in
11129 $ac_executable_extensions when looking for programs.
11131 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11133 * lib/autoconf/general.m4: Fix a small Englisho.
11134 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
11135 setting up ac_dir_suffix and ac_top_builddir.
11136 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
11138 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11140 * doc/autoconf.texi (File System Conventions): Clarify the use of
11141 PATH_SEPARATOR.
11142 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
11143 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
11144 be used instead of ':'.
11145 * lib/autotest/general.m4: Replace occurrences of ':' in
11146 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11148 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11150 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11151 arguments. Fixed a typo.
11153 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11155 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11156 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11158 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11160 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11161 * bin/autoupdate.in: Ditto.
11162 * bin/autoheader.in: Reworded a few comments.
11163 * bin/autoconf.in: Reworded help text for a few options.
11164 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
11165 * bin/autoscan.in, bin/autoupdate.in: Ditto.
11167 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11169 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11170 already have $file). Set output files to binary mode (helps avoid
11171 CR issues on DOSish systems).
11173 2001-09-19 Akim Demaille <akim@epita.fr>
11175 * lib/autotest/general.m4: Englishoes.
11176 From Tim Van Holder and Alexey Mahotkin.
11178 2001-09-18 Paul Eggert <eggert@twinsun.com>
11180 * doc/autoconf.texi (Common Shell Constructs): New node,
11181 documenting AS_DIRNAME.
11182 (Limitations of Usual Tools): Refer to it when discussing dirname.
11183 Also, update discussion of POSIX standard to reflect latest draft.
11185 * lib/autoconf/c.m4:
11186 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11188 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11189 Do not pass a first argument with leading '-'
11190 to expr, by parenthesizing initial integers that might be negative.
11192 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11193 now merely checks whether it is an error to pass an argument
11194 to getpgrp.
11196 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11197 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11198 whether it is a (compile-time) error to pass an argument to
11199 getpgrp. This simpler test supports the revised documentation,
11200 and is all that AC_FUNC_GETPGRP's users really need.
11202 2001-09-18 Akim Demaille <akim@epita.fr>
11204 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11206 2001-09-18 Akim Demaille <akim@epita.fr>
11208 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
11209 `{}'.
11210 * lib/autotest/general.m4 (AT_INIT): Adjust.
11212 2001-09-18 Paul Wagland <paul@wagland.net>
11214 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11215 correctly.
11216 Add test for AS_BASENAME.
11217 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11218 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11219 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11220 * tests/base.at: Fixed the expected responses. The old ones were
11221 one line out...
11222 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11223 the documentation claims it should (and how it behaved in 2.13).
11225 2001-09-18 Akim Demaille <akim@epita.fr>
11227 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11228 the AC_CONFIG_COMMANDS invocation.
11229 This also solves the name clash problems.
11230 Don't set the package's ID.
11231 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11232 No longer to be shipped.
11233 (version.in): Remove.
11234 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11235 * lib/autoconf/status.m4: Adjust.
11236 Use `m4_PACKAGE_STRING'.
11237 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11238 the only optional argument is the name of the test suite.
11239 Expect `package.m4' to define the package signature.
11240 * lib/autom4te.in (Autotest): Add `package.m4?'.
11241 * tests/Makefile.am (package.m4): New.
11242 * tests/suite.at: ifnames is a victim.
11244 2001-09-18 Akim Demaille <akim@epita.fr>
11246 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11247 AC_LIBSOURCE, AC_CONFIG_FILES.
11248 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11249 program version string doesn't match the package's.
11250 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11251 after `(cached)'.
11253 2001-09-17 Paul Eggert <eggert@twinsun.com>
11255 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11256 Allow expression to return any value that can fit into unsigned long
11257 (not int, as before). Check for output errors.
11259 2001-09-17 Bruno Haible <haible@ilog.fr>
11261 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11262 Always include <stdio.h> and <stdlib.h>. Evaluate
11263 the expression in an extra function before these includes. Call
11264 fprintf "%d" only after ensuring the argument is of type 'int'.
11265 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11267 2001-09-17 Paul Eggert <eggert@twinsun.com>
11269 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11270 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11271 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11272 when they don't exist.
11274 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11275 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11276 need it.
11278 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11279 version with the version used by fileutils 4.1, except use
11280 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11281 we don't need it.
11283 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11285 2001-09-13 Akim Demaille <akim@epita.fr>
11287 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11288 _first_.
11289 Reported by Gerrit P. Haase.
11291 2001-09-13 Akim Demaille <akim@epita.fr>
11293 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
11294 m4_defn'ing is valid.

11300 Use it.

11314 AT_tests_all for consistency.
11315 Set at_victims.
11316 (AT_VICTIMS): Similar to AT_KEYWORDS.
11317 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11319 2001-09-13 Akim Demaille <akim@epita.fr>
11321 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11323 2001-09-13 Akim Demaille <akim@epita.fr>
11325 * lib/autotest/general.m4 (AT_INIT): Create and remove
11326 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11327 test suites can cohabit.
11329 2001-09-13 Akim Demaille <akim@epita.fr>
11331 * tests/mktests.sh: Don't output banners for empty test files.
11333 2001-09-13 Akim Demaille <akim@epita.fr>
11335 Test suites can be run independently of configure.

11435 * bin/autom4te.in: --language is -l, not -s.
11437 2001-09-05 Akim Demaille <akim@epita.fr>

11440 the maintainer is dumb enough to do that...
11442 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11443 excellence in M4 quotation: consider `__file__' is active.

11476 New, extracted from main.
11477 Use IO::File wherever possible.

11480 Don't invoke `_au_disable', since ac was not loaded, but just

11483 2001-08-31 Akim Demaille <akim@epita.fr>

11510 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11511 (testsuite Scripts): There is no such thing as `atconfig.in'.

11516 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

11531 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11532 debug scripts, in particular passing explicitly listed tests to
11533 run is stupid.
11535 2001-08-31 Akim Demaille <akim@epita.fr>
11537 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11538 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11539 Use directly autom4te, not autoconf.

11564 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11565 (autoheader): Pass --force since the test suite goes too fast for
11566 the time stamps.

11582 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11583 `autoheader: `config.hin' is created'.
11584 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11586 2001-08-31 Akim Demaille <akim@epita.fr>
11588 * bin/autoheader.in: Rewrite in Perl.
11589 * tests/autoheader: Adjust.
11591 2001-08-31 Akim Demaille <akim@epita.fr>
11593 * bin/autoconf.in (--include, -I): New option.
11594 Map --localdir, --autoconf-dir onto it.
11595 Forward autom4te's options instead of interpreting them.
11596 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11597 There is no such envvar since the inception of autom4te.cfg.
11598 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11599 * bin/autoupdate.in: Adjust, and perform more control.
11600 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11601 * tests/autoconf: Dittowise.
11603 2001-08-31 Akim Demaille <akim@epita.fr>
11605 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11606 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11607 optionally `FILE'.
11608 Use -e, not -f, since /dev/null for instance is OK.
11609 (&parse_args): Adjust.
11610 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11612 2001-08-31 Akim Demaille <akim@epita.fr>
11614 * configure.ac: Also find tested executables in bin.
11615 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11616 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11617 installed peer executables, only PATH is allowed to resolve it.
11618 Pass `autoconf_dir' via options, not via invisible envvars.
11619 * lib/Autom4te/General.pm (&find_peer): Remove.
11620 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11621 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11622 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11623 find the executables for it.
11624 * tests/Makefile.am: Major cleanup. Too lazy to document...
11625 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11626 We only need PERL.
11627 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11628 indeed related to running the test suite, while passing
11629 --autoconf-dir and others is related to running non installed
11630 Autoconf executables. So don't do that, leave it to...
11631 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11632 * tests/autoscan: New.
11633 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11634 refer to library files: rely on --language.
11636 2001-08-29 Akim Demaille <akim@epita.fr>
11638 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11639 s/--set/--language/.
11641 2001-08-29 Akim Demaille <akim@epita.fr>
11643 * doc/autoconf.texi: Strip the @nodes.
11644 Suggested by Paul Eggert.
11645 (Initializing configure): Typo.
11647 2001-08-29 Akim Demaille <akim@epita.fr>
11649 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11650 Suggested by Paul Eggert.
11652 2001-08-29 Akim Demaille <akim@epita.fr>
11654 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11655 download in a tmp dir.
11657 2001-08-29 Akim Demaille <akim@epita.fr>
11659 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11660 case insensitive OSes out there :(

11665 * lib/autom4te.in: New.

11670 (&parse_args): Support --mode, --set, and --melt.
11671 * bin/autoconf.in: Simplify and adjust.
11672 * tests/Makefile.am (AUTOMAKE): Use --set.
11673 * tests/atlocal.in: Adjust.
11674 * BUGS: distcheck and check are weak.
11676 2001-08-29 Akim Demaille <akim@epita.fr>
11678 * lib/autotest/general.m4: Use
11679 foo=`(command) 2>/dev/null`
11680 not
11681 foo=`command` 2>/dev/null
11682 (at-devnull): Rename as...
11683 (AT-devnull): this.
11684 (--clean): Remove AT-* files too.
11685 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11686 Reported by Nicolas Joly.

11690 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11696 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11698 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11700 * lib/autotest/general.m4: Reword some messages.
11701 (AT_INIT): Check for the `times' builtin before using it.
11702 Support test ranges as arguments to the testsuite.
11703 Have -e imply -d as the help text suggested.
11705 2001-08-27 Akim Demaille <akim@epita.fr>
11707 * Makefile.maint: Formatting changes.
11708 (do-po-update, po-update, cvs-update, update): New targets.

11720 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11721 Support `VAR=VAL' as arguments.

11723 may be set via the command line.
11725 2001-08-27 Akim Demaille <akim@epita.fr>
11727 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11728 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11729 first the build dirs, then the src dirs.

11732 2001-08-27 Akim Demaille <akim@epita.fr>
11734 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11735 at_data_files earlier.
11736 (--clean, -c): New option.
11737 * tests/Makefile.am: Use this option.
11739 2001-08-27 Akim Demaille <akim@epita.fr>
11741 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11742 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11743 readable.
11744 Adjust callers.
11745 * doc/autoconf.texi (Configuration Actions): Document the vars
11746 available in commands.
11747 Emphasize the risks of collisions in init-cmds.

11751 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11752 (Initializing configure): this new node.
11754 2001-08-27 Akim Demaille <akim@epita.fr>

11777 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11778 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11779 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11780 -> ac_dir).
11781 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11782 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

11810 (AMTAR): Help automake define it.

11812 needed, 1.5 can have a macro and a target with the same name.
11813 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11814 * m4/strip.m4: New.

11827 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11828 Adjust callers.
11829 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11830 the name of the directory they're in, instead of the filename,
11831 since version.m4 is now in m4sugar, but m4_acversion must not be
11832 classified as an Autoconf macro.
11833 ($input_m4): Don't qualify the path to m4sugar.
11834 Rather, pass autoconf_dir to m4.
11835 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11836 * tests/suite.at: Require 2.52c.
11838 2001-08-27 Akim Demaille <akim@epita.fr>

11850 of config.log on traps.
11851 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11852 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11853 for config.status'.
11854 Open the log as soon as possible.
11855 Use the same log introduction as configure's.
11857 2001-08-22 Paul Eggert <eggert@twinsun.com>
11859 * doc/autoconf.texi (Indices): New node.
11860 Move indices out of the top level menu and into this submenu.
11862 2001-08-22 Akim Demaille <akim@epita.fr>
11864 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11865 AC_TRY_COMMAND.
11866 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

11913 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11914 program with AC_LANG_PROGRAM before feeding it to
11915 AC_COMPILE_IFELSE. Cleanup grep usage.
11917 2001-08-20 Akim Demaille <akim@epita.fr>
11919 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11920 * NEWS, README, README-alpha, TODO, tests/README: This package is
11921 `Autoconf', not `autoconf' (the executable).
11923 2001-08-20 Akim Demaille <akim@epita.fr>
11925 Info readers seem to need `Index' in the index node title :(
11927 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11928 simplified index node names.
11930 2001-08-20 Akim Demaille <akim@epita.fr>
11932 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11933 arguments are not literals.

11935 Specify the output variables, and macros defined.
11937 2001-08-20 Akim Demaille <akim@epita.fr>
11939 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
11940 (Examining Syntax) <AC_TRY_COMPILE>
11941 (Examining Libraries) <AC_TRY_LINK>
11942 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
11943 their arguments.
11944 Reported by Werner Lemberg.
11946 2001-08-20 Akim Demaille <akim@epita.fr>

11963 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.

11965 test suite lives.
11966 Create `atconfig' automagically.

11972 2001-08-20 Akim Demaille <akim@epita.fr>
11974 Huh!?!?! There are still some user EOF tags used, which prevents
11975 their use in AC_CONFIG_COMMANDS for instance...
11977 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11978 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11979 `_CSEOF', or `_ATEOF', as appropriate.
11980 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
11981 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

12059 * doc/autoconf.texi: Work around Texinfo buglets.

12114 (cvs-dist): depends upon it.
12116 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12118 * tests/Makefile.am: Use a clean-local rule to remove
12119 autom4te.cache (it's a directory, not a file.
12120 * Makefile.am: Ditto (but maintainer-clean-local).
12122 2001-08-15 Akim Demaille <akim@epita.fr>
12124 * bin/autom4te.in (@m4_warning): New.
12125 (&handle_m4): Use it.
12126 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12127 warnings are issued at each run.
12128 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12129 is in the src tree.
12131 2001-08-15 Akim Demaille <akim@epita.fr>
12133 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12134 don't waste time running `autoupdate --version' works.
12135 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12137 2001-08-13 Akim Demaille <akim@epita.fr>

12199 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12200 * doc/autoconf.texi (C Compiler Characteristics): Update

12205 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12206 magic values from an object file when cross-compiling.
12207 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12209 2001-08-10 Akim Demaille <akim@epita.fr>
12211 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12212 effects.
12213 Suggested by Russ Allbery.
12215 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12217 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12218 current $prefix to the sub-configures.
12220 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12222 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12223 extension (needed on BeOS). Reported by Guido van Rossum.
12225 2001-08-09 Akim Demaille <akim@epita.fr>
12227 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12229 2001-08-07 Akim Demaille <akim@epita.fr>
12231 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12232 removed.
12233 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12234 No need to remove the files before and after the each test, before
12235 each test and at the end of the suite is enough.
12236 Display only the children `times', not the shell's.
12237 If the test failed or was skipped, at-times is not available.
12239 2001-08-07 Akim Demaille <akim@epita.fr>
12241 Always produce testsuite.log, including when there are no
12242 failures. This helps getting information on skipped tests, and
12243 duration of the tests. Err, implement the latter btw.
12245 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12246 Dump information on the first run of each test.
12247 (AT_CLEANUP): Create `at-times' containing the duration of the
12248 test group.
12250 2001-08-07 Akim Demaille <akim@epita.fr>
12252 The use of `dumpstat' revealed that `len' was used although it
12253 should not. m4_text_wrap was using it, but in the Autoconf world
12254 where it is legal. Hence (i) test M4sh in its own world, not
12255 Autoconf's, and (ii), ahem, fix the bug :)
12257 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12258 does not like `' instead of [].
12259 (AT_INIT): Forbid `^_?AT_'.
12260 And don't output such tokens.
12261 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12262 `script.as', and `autom4te.cache'.
12263 Remove `empty' and `macro' which are no longer used.
12264 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12265 * tests/m4sugar.at: Use it.
12266 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12268 2001-08-07 Akim Demaille <akim@epita.fr>
12270 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12272 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12274 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12276 2001-08-04 Akim Demaille <akim@epita.fr>
12278 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12279 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12280 AC_TRY_LINK.
12281 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12282 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12283 (AC_F77_MAIN): Likewise.
12285 2001-08-04 Akim Demaille <akim@epita.fr>
12287 Don't rely on M4sugar outputting the patterns in files, since we
12288 might process the output _without_ running m4, hence without these
12289 files.
12291 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12292 * bin/autom4te.in (@Request::includes): Remove, unused.
12293 (@Request::source): Rename as...
12294 (@Request::input): this.
12295 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12296 (&handle_output): Fetch the patterns from the traces.
12297 `$forbidden' and `$allowed' are constant: use m//o.
12298 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12299 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12301 2001-08-04 Akim Demaille <akim@epita.fr>
12303 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12304 autoconf', i.e., in addition to caching traces, cache the output.
12306 * bin/autom4te.in (Request::cache): Rename as...
12307 (Request::id): this.
12308 ($cache, $icache, $tcache, $ocache): New.
12309 (&handle_m4): Save M4 output in the cache instead of $tmp.
12310 (&handle_output): Adjust.
12311 (&up_to_date_p): Check that the output cache is up to date too.
12312 (top level): Run `&handle_m4' iff force or the cache is invalid.
12313 Run `&handle_output' if the output cache is more recent.
12315 2001-08-04 Akim Demaille <akim@epita.fr>
12317 * bin/autom4te.in ($force): New.
12318 (&parse_args, &print_usage): -f, --force is a new option.
12319 (&handle_output): CPP directives might have spaces after `#'.
12320 (&parse_args): The first file only can be frozen.
12322 2001-08-04 Akim Demaille <akim@epita.fr>
12324 Don't let autom4te compute the `include' traces several times:
12325 first check that the trace cache file is up to date, and then
12326 compare its timestamp with that of the output.
12328 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12329 the preamble. Don't require 5.005 as Autom4te::General does it,
12330 and better yet (use `use', not `require'!).
12331 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12332 Class::Struct as Autom4te::Struct.
12333 * lib/Autom4te/General.pm (File::stat): Use it.
12334 (&mtime): New, export it.
12335 * bin/autom4te.in: Use it.
12336 Declare `$req' is invalid if it is outdated.
12337 Don't declare it valid before saving it if something went wrong.
12339 2001-08-04 Akim Demaille <akim@epita.fr>
12341 Autom4te shall not encode Autoconf data, and preselecting traces
12342 must be proposed to the users.
12344 * bin/autom4te.in (@required_trace): Remove.
12345 (@preselect): New.
12346 (&parse_args, &print_usage): -p, --preselect is a new option.
12347 (&up_to_date_p): Adjust.
12348 * bin/autoconf.in: Preselect some Autoconf macros.
12350 2001-08-04 Akim Demaille <akim@epita.fr>
12352 * tests/tools.at (autoconf --trace: user macros): Check traces on
12353 macros invoked without arguments, and macros invoked with multiple
12354 lines arguments.
12356 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12358 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12359 arguments.
12361 2001-08-03 Akim Demaille <akim@epita.fr>
12363 * bin/autoconf.in ($@): Work around the usual sh bug.
12364 From Nicolas Joly.
12366 2001-08-03 Akim Demaille <akim@epita.fr>
12368 Clean up the handling of the M4 builtins tracing exception.
12370 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12371 trace requests.

12373 (@m4_builtin): this.
12374 (%m4_builtin_alternate_name): New.
12375 (&parse_args): Complete the trace requests with alternate names.
12376 (&handle_traces): Hence no longer do it here.
12377 (&trace_requests): Remove, unused.
12379 2001-08-03 Akim Demaille <akim@epita.fr>
12381 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12382 m4_if, and m4_wrap.
12384 2001-08-03 Akim Demaille <akim@epita.fr>
12386 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12387 (m4_divert_pop): Dump the whole diversion stack when a diversion
12388 mismatch happens.
12389 * bin/autom4te.in (&handle_output): Remember of the first
12390 occurrence of a possibly undefined macro, not the last.
12391 Complain about the possibly undefined macros in the same order as
12392 the appear in the output.
12393 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12394 * tests/tools.at (autoconf: forbidden tokens, basic)
12395 (autoconf: forbidden tokens, exceptions): No longer sort
12396 autoconf's stderr, as it is now deterministic.
12397 Check that `dnl' is caught.
12399 2001-08-01 Akim Demaille <akim@epita.fr>
12401 * configure.ac: Bump to 2.52c.

12416 `die'.
12417 (&END): New.
12418 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12419 `END', as `Autom4te::General::END' will be triggered.
12420 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12421 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12813 compiler, not the preprocessor.
12814 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

12816 the right thing.

12818 earlier if there are.
12820 2001-07-03 Akim Demaille <akim@epita.fr>

12849 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
12850 dummy alternate main is required even if the user provides her own
12851 'main'.
12852 (AC_F77_MAIN): New macro to detect whether it is possible to
12853 provide an alternate 'main' function name, using the 'main' from
12854 the Fortran libraries.
12855 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12856 cross-language link tests can be performed successfully.
12857 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12858 after $LIBS, for consistency; this should be the general rule since
12859 the user may want to link to Fortran libraries that require $FLIBS.
12860 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
12862 2001-06-29 Pavel Roskin <proski@gnu.org>
12864 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
12865 at-stdout and at-stderr instead of removing the newline
12866 from the echo output, which is not guaranteed to work.
12868 2001-06-28 Jens Petersen <petersen@redhat.com>
12870 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

12902 explicit macros is mapped to the default macro.
12903 (&print_unique): Remove, inlined in...
12904 (&output_kind): here.
12905 (File::Basename): Use it.

12913 characteristics in the logs.
12914 Suggested by Mo DeJong.
12916 2001-06-24 Akim Demaille <akim@epita.fr>

12927 2001-06-23 Akim Demaille <akim@epita.fr>
12929 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
12930 three as failures are unlikely, and speed matters.
12932 2001-06-23 Akim Demaille <akim@epita.fr>
12934 * doc/autoconf.texi (Redefined M4 Macros): New.
12936 2001-06-23 Akim Demaille <akim@epita.fr>
12938 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
