3 * NEWS: New macro AC_PROG__MKDIR_P. AS_MKDIR_P is now more robust.
4 * config/install-sh: Don't use 'path' to talk about file names,
5 as per GNU coding standards. Close a race condition reported by Ralf
6 Wildenhues and Stepan Kasal. There is still a race condition
7 on hosts that predate POSIX 1003.1-1992, but we can't help this.
8 Don't mishandle weird characters like space on pre-POSIX hosts.
9 Invoke mkdir at most once per dir arg on pre-POSIX hosts.
10 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11 AC_PROG_MKDIR_P from AS_MKDIR_P.
12 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
13 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
14 earlier editions are not (including Automake 1.8.3).
15 Do not suggest mkinstalldirs for thread-safety.
16 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
17 presence of special characters and race conditions.
18 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
19 in Autoconf's name space.
21 2006-05-10 Bruno Haible <bruno@clisp.org>
22 and Paul Eggert <eggert@cs.ucla.edu>
24 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
25 from Automake with minor changes.
26 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
28 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
30 * config/install-sh: Update to Automake CVS version, as follows:
31 2006-04-25 Stepan Kasal <kasal@ucw.cz>
32 * lib/install-sh: Simplify the expr implementation of dirname.
33 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
34 * lib/install-sh: Handle --, and diagnose unknown options.
36 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
39 `./autom4te' to create `./testsuite', since the `all' target
40 will ensure its presence, but `installcheck' should not create
41 the uninstalled wrappers.
43 * tests/torture.at (Unusual Automake input files): Skip if we
44 detect automake < 1.8.
46 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
48 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
49 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
50 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
51 * NEWS: Update.
53 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
55 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
56 munge (multiple) white space and other oddities.
57 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
58 single quotes in variable assignment.
59 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
60 and similar failures by adding multiple spaces, tabs, and other
61 special characters.
62 Report and different test suggested by Francesco Romani
63 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
65 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
66 single quotes, we only need to search for single quotes; this
67 both simplifies the search pattern, and makes us less
68 susceptible to `echo' variations for arguments not containing
69 single quotes.
70 (_AC_ARG_VAR_VALIDATE): Likewise.
72 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
74 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
75 `$*' and IFS concatenation issue with traditional shells and
76 bash-2.04. Report by Seanster@Seanster.com.
78 2006-05-03 Bruno Haible <bruno@clisp.org>
80 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
81 precisely which Mac OS X versions have the od problem.
83 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
85 * doc/autoconf.texi: Use @option systematically.
86 (Integer Overflow):
88 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
89 and Bruno Haible <bruno@clisp.org>
91 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
92 about 'od'.
93 (Integer Overflow): Mention the special case of integer division
94 overflow.
96 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
98 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
99 traditional shells like the Solaris one that do not use the
100 first IFS character for assembling `$*'.
101 Prompted by a related report from autoconf_bug@nro.ca.
103 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
104 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
106 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
107 Mention more problems with the -e option.
109 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
111 * NEWS: Typo.
112 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
114 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
115 in URLs to improve DVI formatted output (requires texinfo 4.6).

117 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
118 output.
120 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
121 continuous text.
122 (Runtime): Fix macro argument names to match description:
123 `action-if-found' -> `action-if-true' and similarly.
124 (Obsolete Macros): Likewise.
125 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
126 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
127 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
129 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
131 * doc/autoconf.texi (Limitations of Make): Clean up markup.
133 * ChangeLog: Typo.
134 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
135 DVI output.
137 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
139 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
140 /bin/sh set unsorted output.
141 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
142 * tests/local.at: Likewise.
144 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>

150 with status 1, not merely nonzero. Clarify exit declaration.
151 (Run Time): Move C exit status stuff to new Exiting Portably section.
152 (Systemology): Mention Posix and levenez. Update v7 reference.
153 (Portable Shell): Mention the Posix shell.
155 2006-04-25 Stepan Kasal <kasal@ucw.cz>
157 * bin/autoconf.as (me): Replace by as_me.
159 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
161 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
162 since as_me isn't set yet.
164 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
166 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
167 a few minor bugs in this area.
169 * doc/autoconf.texi (Programming in M4sh): Comment out the
170 documentation of AS_BASENAME, for now.
171 (Shell Substitutions): Do not use AS_DIRNAME in an example.
172 (Limitations of Builtins) <basename>: Do not refer to
173 AS_BASENAME.
174 * bin/autoconf.as (me): Don't use AS_BASENAME.
175 (dir): Remove the unused variable.
176 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
177 AS_DETECT_REQUIRED. All uses changed.

179 All uses changed.
180 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

182 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
183 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
184 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
185 (_AS_DIRNAME_PREPARE): Likewise.
186 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
187 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
188 (AS_DIRNAME): Use "dirname --".
190 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
192 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
193 of "run time" and "run-time" changed to "runtime", for consistency.
194 * lib/autoconf/fortran.m4: Likewise (in comment).
195 * lib/autoconf/functions.m4: Likewise.
196 * lib/autoconf/general.m4: Likewise.
197 * lib/autoconf/headers.m4: Likewise.
199 * doc/autoconf.texi (Run Time): Document the exit status situation
200 with more accuracy and detail.
202 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
204 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
205 Archive is not officially `GNU' any more. Update URL.
206 (Defining Directories): Likewise
207 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
209 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
211 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
212 newline from the `trap' code to finish `config.log'; the NetBSD
213 /bin/sh resets the exit status after an empty command, as
214 documented in doc/autoconf.texi.
215 Reported by Dalibor Topic <robilad@kaffe.org>.
217 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
219 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
220 Suggested by Bruno Haible.
222 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
224 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
225 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
226 Instead, just list the shells that we know work.
227 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
228 changed. Be more cautious about the _cv_ variable.
229 * tests/tools.at (Syntax of the shell scripts): Check the
230 _cv_ variable once, at first, to avoid an internal autoconf error
231 when sh -n does not work.
233 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
235 * lib/Autom4te/FileUtils.pm: Sync from Automake.
237 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
239 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
240 use ">&-" since we're only 99.999% sure that this is portable,
241 and since the MinGW bug is fixed in a different way.
242 * lib/autotest/general.m4 (AT_INIT): Likewise.
244 2006-04-16 Stepan Kasal <kasal@ucw.cz>
246 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
247 before opening config.log, to avoid hitting a bug on MinGW.
249 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
251 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
252 AS_MESSAGE_LOG_FD before reopening it onto the log file.
253 This works around a MinGW bug reported by Eric Paire.
254 Make sure that all writes to the log file append to it,
255 rather than possibly losing data.
256 * lib/autotest/general.m4 (AT_INIT): Likewise.
258 2006-04-14 Stepan Kasal <kasal@ucw.cz>
260 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
261 description.
263 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
265 * NEWS: Update.
267 * configure.ac (AC_INIT): Bump to 2.59d.
269 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
271 Version 2.59c.
273 * Makefile.maint (news-date-check): Do not require a leading `*'
274 before the release date in NEWS.
276 2006-04-12 Stepan Kasal <kasal@ucw.cz>
277 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
279 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
280 the instantiated file do not contain the string 'datarootdir'
281 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
282 @mandir@, replace the reference '${datarootdir}' by the value.
283 * tests/torture.at (datarootdir workaround): New test.
284 * NEWS: Advertise this temporary fixup.
285 Based on a patch by Bruno Haible, reported and analyzed by
286 Paul Eggert and Noah Misch.
288 2006-04-12 Eric Blake <ebb9@byu.net>
290 * tests/autotest.at (Debugging a failed test): Fix comment.
292 2006-04-12 Stepan Kasal <kasal@ucw.cz>
294 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
295 all the changes since 2006-04-07.
297 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
299 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
300 succeeded, but `ln -s file dir' failed, take care to remove the
301 leftover target before the next test, to prevent its spurious
302 failure; also make sure `ln file dir' works before selecting it.
303 Thanks to Keith Marshall for pointing this out.
304 * THANKS: Update.
306 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
307 assignments in `at_debug_args', so that we put them correctly
308 in the `run' script.
309 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
310 Reported by Eric Blake.
312 2006-04-11 Eric Blake <ebb9@byu.net>
314 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
315 top-level tests after micro-suite has been run. Used in...
316 (Debugging a successful test, Debugging script and environment),
317 (Debugging a failed test): ...these new tests. The first of these
318 is fixed by...
319 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
320 macro, split out from...
321 (AT_INIT): ...here, so that using -d also generates a run script.
322 Document that -d inhibits top-level logging.
323 * doc/autoconf.texi (testsuite Invocation): Document that -d only
324 inhibits top-level logging; debug scripts are created.
326 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
327 check.
328 * tests/autotest.at (Empty test, Empty check): New test to check it.
330 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
331 from gcc.
333 2006-04-10 Stepan Kasal <kasal@ucw.cz>
335 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
336 the files if a problem appears. Make the empty *.at files
337 read-only, too. Proposed by Ralf Wildenhues.
339 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
341 * config/Makefile.am: Add comment to force updated Makefile.in.
343 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
344 space only patch to this file, this patch causes the Makefile.in
345 files that include freeze.mk to be updated, and thus have a
346 newer time stamp again, which in turn makes a pristine CVS
347 checkout have correct time stamps.
349 * Makefile.maint (cvs-sv): New macro, to be used..
350 (config.guess-url_prefix, config.sub-url_prefix)
351 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
352 point to CVS text checkout of Gnulib files.
353 (copyright-check): Bump current year.
354 (announcement): Do not hard-wire `./announce-gen'.
355 (cvs-update): Propagate failures of `cvs' and `move-if-change'
356 correctly.
357 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
358 `chmod +x'.
359 (wget_files): Update config.guess, config.sub, texinfo.tex by
360 `wget-update', now that their URLs work again.
362 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
364 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
365 Problem noted by Paul D. Smith.
367 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
369 * doc/autoconf.texi: Remove unused words from word list.
370 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
371 .x-sc_trailing_space: New files.
373 * doc/standards.texi: Sync from gnulib.
375 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
376 `LIBOBJDIR' as experimental.
378 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
379 with a target directory; it's internally implemented as `cp'
380 anyway, but since Autoconf advertises the possibility to use
381 a target directory when LN_S is `ln -s', we need to find out.
382 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
383 analyzed by Keith Marshall <keith.marshall@total.com>.
385 * THANKS: Update.
387 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
389 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
390 confdefs.h as-is. In general, if it has backslash-newline or the
391 like, then it doesn't work either to sort or to remove empty
392 lines.
394 2006-04-09 Stepan Kasal <kasal@ucw.cz>
396 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
398 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
400 * lib/autom4te.in (Automake-preselections): Preselect
401 _AM_SUBST_NOTMAKE.
403 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
405 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
406 apostrophe within a single-quoted string, as this is the usual
407 tradition and is easier to read than '"'"'. Don't rely on the
408 shell treating "$/" like '$/'. Use a more-consistent indenting
409 style for the trap.
411 2006-04-09 Eric Blake <ebb9@byu.net>
413 * tests/autotest.at (Backquote command substitution),
414 (Multiline backquote command substitution): Remove mistaken
415 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
416 applied...
417 (Parenthetical command substitution, Multiline parenthetical
418 command substitution): here.
420 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
422 Import macros from gnulib (often changing their name).

438 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
439 Gnulib section.
440 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
441 suggest a #define rather than a typedef for _Bool, and mention
442 Gnulib rather than trying to substitute stdbool code.
443 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
444 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
445 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

450 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
451 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
452 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
453 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
454 (C Compiler): Move AC_C_LONG_DOUBLE to ...
455 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
456 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
457 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
458 (Coding Style). Don't mention m4_expand_once.
459 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

469 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
470 Catch a bug in an HP-UX C compiler.

493 that contains braces.
495 2006-04-07 Stepan Kasal <kasal@ucw.cz>
497 Revert the patch from 2006-04-01 and only improve
498 _AS_DETECT_BETTER_SHELL:
500 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
501 skip nonexistent directories.
502 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
503 only shell candidates which exist.
504 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
505 * lib/autotest/general.m4 (AT_INIT): No need to give three
506 parameters to _AS_PATH_WALK.
508 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
509 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
511 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
512 distinguish m4sugar macros.
513 * tests/tools.at (autoupdating with aclocal and m4_include):
514 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
515 test case by Noah Misch <noah@cs.caltech.edu>.
517 2006-04-07 Stepan Kasal <kasal@ucw.cz>
519 Revert my change from 2006-03-17, in other words:
520 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
521 and DUALCASE=1.
522 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
523 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
524 it is set.
526 2006-04-07 Eric Blake <ebb9@byu.net>
528 * doc/autoconf.texi (Programming in M4sh): Document that
529 AS_MKDIR_P exits the script on failure.
530 * lib/autotest/general.m4: Remove redundant AS_ERROR.
532 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
534 * config/elisp-comp, config/install-sh, config/mdate-sh,
535 config/missing, config/mkinstalldirs: Sync from Automake.
537 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
538 from Automake.

549 Eric Blake <ebb9@byu.net>,
550 Paul Eggert <eggert@cs.ucla.edu>,
551 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
553 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
554 whether `set' quotes correctly: redirect stderr of the tested
555 `set', and use a subshell, for Ultrix; use `sed' instead of
556 `grep' for zsh `set' which may write binary output; match only
557 at the beginning of a line, to avoid false positives.
558 In order to avoid false positives by unrelated variables with
559 multiline content, put the dump algorithm in a subshell and
560 unset all variables containing newlines (except some which are
561 special to the shell). Warn about cache variables that are
562 unset.
564 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

575 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
576 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
577 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
578 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
580 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
581 shell issue with double-quoted command substitutions of native
582 commands.
583 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
584 Marshall.
586 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

593 (sc_system_h_headers): Do not print rule on execution.
594 (sc_tight_scope): Do not fail for non-existing `src' directory.

604 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
606 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
607 ac_config_<foo>s again, sometimes normalized, sometimes not.
608 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
609 (AC_CONFIG_COMMANDS): Do not do so here.
610 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
611 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
612 2005-07-25 rewrite. Noticed by Noah Misch.
614 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
615 _AC_PRESERVE_HELP_ORDER, ...
616 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
618 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
619 inside m4_expand_once; it is redundant.
621 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
622 for --help from Cygnus `configure.'
624 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

635 Noah Misch <noah@cs.caltech.edu>
637 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
638 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
639 * doc/autoconf.texi (Help Formatting): New node.
640 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
642 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

645 lib/autoconf/specific.m4, lib/autoconf/status.m4,
646 lib/autoconf/types.m4, lib/autotest/general.m4,
647 tests/mktests.sh, tests/torture.at: White space cleanup:
648 remove some SPACE before TAB, or add quoting ('' or @&t@).

654 2006-04-05 Eric Blake <ebb9@byu.net>
656 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
657 empty test suite works.
658 * tests/autotest.at (Empty test suite): Remove xfail.

672 Use simplified args that Eric Blake originally suggested.
674 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
676 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
677 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
678 Use 'comm' rather than N instances of grep; this also fixes a bug
679 whereby substrings were incorrectly matched, causing us to not
680 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
681 (exclude_list): Exclude empty macros.
682 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
684 Use awk rather than grep -E or egrep, to avoid
685 portability problems with regular expressions containing newlines.
686 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
687 Switch from grep to awk syntax.
688 (ac_exclude_script): Renamed from ac_exclude_egrep.

697 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
698 report request when we have no AC_PACKAGE_BUGREPORT.
700 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

732 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
733 to log, point to testsuite output tree.
735 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

763 Clean up _AC_COMPILER_EXEEXT* macros.
765 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
766 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
767 ac_file to the name of the default output filei and call
768 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
769 initial `rm' of the candidate files...
770 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
771 the same list in subsequent `rm' calls, and for the temporary
772 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
773 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
774 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
775 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
776 no longer needed) by libtool. Make it a cache check.

778 copied here by mistake.
779 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
780 _AC_COMPILER_EXEEXT.

817 subordinate tools.
818 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
819 * doc/autoconf.texi (autoreconf Invocation): Document it.
821 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
822 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

837 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.

839 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
840 AC_DEFUN this for autoconf, including the obsoletion diagnose.

842 m4sugar macros.
843 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
844 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

850 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
851 Kristian Kvilekval <kris@cs.ucsb.edu>.
853 2006-04-01 Stepan Kasal <kasal@ucw.cz>
855 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
856 switch all of them on and of when necessary. Fixes the bug when
857 m4sugar macros (e.g., m4_define) were expanded after the first
858 automatic update (e.g., after AC_PREREQ or AC_INIT).
860 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

891 (File System Conventions): Put discussion of // versus / here, and
892 modernize it a bit.
893 (Limitations of Usual Tools): Add basename. Remove verbiage
894 after dirname, since it got moved to the above sections.
895 All this was inspired by a patch proposed earlier by Eric Blake.

908 checked for existence, so we don't barf over a nonexisting
909 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
911 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1405 rather than "sed" when talking about Sed in general.
1406 (Particular Programs): Likewise.
1407 (Coding Style): y is like s with respect to / and ,.
1408 (Limitations of Usual Tools): Document the weird restrictions
1409 that Posix has about { }. Use better quoting.
1410 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
1411 Rewrite to conform to Posix rules about { } in sed scripts.
1412 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
1413 * tests/foreign.at (Libtool): Likewise.
1414 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):
1415 Use our own style advice re 's,a,b,' versus 's|a|b|'.

1430 shell from zsh to bash.
1432 2005-12-31 Stepan Kasal <kasal@ucw.cz>
1434 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
1435 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
1437 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
1439 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
1440 parentheses in $(...). Problem reported by Eric Blake.

1470 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1472 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
1473 CONFIG_SHELL in the environment of the configure rerun.
1474 * doc/autoconf.texi (Here-Documents, config.status Invocation):
1475 Suggest passing CONFIG_SHELL absolute, and in the environment
1476 rather than as option.
1478 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1480 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

1491 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
1492 ac_clean_files and LIBOBJS.
1494 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1496 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
1497 Factor functionality to..
1498 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
1499 `AC_SUBST($1)' in the public version.
1500 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
1501 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
1502 ac_pt_* variables.
1504 2005-11-01 Stepan Kasal <kasal@ucw.cz>
1506 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
1507 filesystems.

1520 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
1521 conftst2.$ac_objext.
1522 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
1524 2005-10-24 Stepan Kasal <kasal@ucw.cz>
1526 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
1527 conftest.o, to see whether the compiler really obeys; rm the object
1528 file before and after the test and register it with ac_clean_files.
1529 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
1531 2005-10-21 Stepan Kasal <kasal@ucw.cz>
1533 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
1534 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
1535 code so that the most common case requires less forks.
1537 2005-10-20 Stepan Kasal <kasal@ucw.cz>
1539 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

1547 the latter'', in two places.
1549 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
1551 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
1552 AC_LANG_PROGRAM, fixing a typo. Don't give details about
1553 the inner workings of AC_LANG_FUNC_LINK_TRY.
1554 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1555 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1556 by the function rather than ignoring it.
1557 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1558 comparing its address. Intel's interprocedural optimization was
1559 outsmarting the old heuristic. Problem reported by
1560 Mikulas Patocka.
1562 2005-10-19 Stepan Kasal <kasal@ucw.cz>
1564 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
1566 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
1568 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

1571 2005-10-04 Stepan Kasal <kasal@ucw.cz>
1573 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
1574 before removing it (chmod -R u+rwx); there are three instances of this.
1576 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1577 Stepan Kasal <kasal@ucw.cz>
1579 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1580 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1581 make its content writable before removing it. Remove an errorneous
1582 comment from the end, where the logs of the failed tests are copied
1583 to the main log file.
1585 2005-09-27 Stepan Kasal <kasal@ucw.cz>
1587 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
1588 in case the computer is too quick. Double quote the configure.ac
1589 snippets.
1591 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
1592 problems if the testsuite were running too fast.
1594 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1596 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1597 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1598 (which belong to Xt, not X itself). See Debian bug 327655.
1599 * NEWS: Mention this.
1601 2005-09-07 Stepan Kasal <kasal@ucw.cz>
1603 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
1605 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
1607 * config/move-if-change: Don't output "$2 is unchanged";
1608 suggested by Ben Elliston. Handle weird characters correctly.
1610 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1612 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1613 calls, so that the final expansion of this macro is shorter.
1614 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1615 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1616 the cleanup there. Use AS_VAR_* macros, to be more general.
1617 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1619 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1621 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
1623 2005-09-01 Stepan Kasal <kasal@ucw.cz>
1625 * doc/autoconf.texi (Configuration Headers): Add an index entry
1626 for AH_HEADER.
1628 2005-08-26 Pavel Roskin <proski@gnu.org>
1630 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
1631 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
1632 running xmkmf.
1634 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1636 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1637 The previous patch didn't work, so try a better one.
1639 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1641 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1642 in the example. Reported by Bruno Haible.
1643 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1644 "if $undefined_var;" succeeds with my shell.
1646 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1647 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1648 but change the m4_divert_text to m4_divert_once.
1650 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1652 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1653 Work around bug in Solaris /usr/xpg4/bin/awk.
1654 The bug is present in at least Solaris 8 through 10.
1656 2005-08-24 Stepan Kasal <kasal@ucw.cz>
1658 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
1659 some evil values and relying on the fact that $* concatenates the
1660 parameters by the first character from IFS.
1662 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1663 Stepan Kasal <kasal@ucw.cz>
1665 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
1666 first header appears, define AH_HEADER.
1667 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1668 Update limitations about when to call AC_CONFIG_HEADERS.
1669 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1670 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1671 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1672 ``Configuration Actions''; fix their index entries.
1674 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1675 options correctly. Process N-M as M-N if M is smaller than N.
1676 Process ranges correctly so that N-N will run only N.
1677 Sort and uniquify the tests that will be run. If there is more
1678 than one test, reinsert the banners for the tests.
1679 * tests/autotest.at (Keywords): Unmark XFAIL.
1681 2005-08-23 Stepan Kasal <kasal@ucw.cz>
1683 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
1684 before passing the macro name to AH_TEMPLATE.
1686 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1687 now opens log after option processing; in particular, --version
1688 and --help do not touch config.log.
1690 * Makefile.maint: Revert the change from 2005-08-12.
1692 2005-08-22 Stepan Kasal <kasal@ucw.cz>

1700 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
1701 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
1702 Language cleanup.
1704 * doc/autoconf.texi (Defining Symbols, Changed Results):
1705 Prepend to LIBS, not append, in examples.
1707 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1709 When building in place, set srcdir="."; suggested by Tim Van Holder.
1711 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1712 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1713 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1714 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
1715 does not mean "no --srcdir option".
1717 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1719 * tests/autoscan.at (autoscan): New file.
1720 * tests/suite.at: Use it.
1721 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
1722 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
1724 * tests/autotest.at (Keywords): Test keywords combinations.
1726 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1728 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1729 add "2>&1"; gzip 1.2.4 prints help on stderr.
1731 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1733 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1734 was pushdef'ed twice while popped only once. Push it only once.
1735 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
1737 2005-07-26 Stepan Kasal <kasal@ucw.cz>
1739 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

1744 * Makefile.maint: Update from Bison.
1746 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
1747 "<tab>" in comment, so that the point is understandable.
1749 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1751 Rewrite substantial part of lib/autoconf/status.m4.
1752 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1753 and CONFIG_COMMANDS are not processed in four separate loops.
1754 Instead, there is one main loop. This alows that the common code
1755 is expanded only once, thus config.status (and configure) is smaller.
1757 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1758 the AC_LIST_FILES and cousins macros are no longer used.
1760 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1761 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1762 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1763 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1764 contain the initialization, nor the for loop, nor the associated
1765 commands; all these go to ...
1766 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1767 _AC_OUTPUT_CONFIG_STATUS.
1768 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1769 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1770 (_AC_OUTPUT_FILE): The creation of the sed script ...
1771 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1772 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1773 _AC_OUTPUT_MAIN_LOOP.
1774 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1775 _AC_CONFIG_COMMANDS): Use ...
1776 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1777 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1778 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1779 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1780 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1781 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1782 ... new macros.
1783 (_AC_CONFIG_UNIQUE): Update.
1784 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1785 Replaced by this ...
1786 (_AC_LIST_TAGS): ... new common macro.
1787 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1788 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1789 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1790 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1791 this didn't belong to the `config commands' section.
1792 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1793 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1794 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1795 to the `config commands' section either.
1796 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1797 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1799 ... and many changes to the comments nearby.
1801 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1802 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1803 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1804 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1805 (#define header templates): The comment at the top of the generated
1806 header now includes the name(s) of the source file(s).
1808 Several unrelated small changes:
1810 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1811 parameter to AC_DIAGNOSE.
1812 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1813 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1814 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1815 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1816 with AU::AC_OUTPUT.
1817 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
1818 in AC_OUTPUT doesn't double-quote it either.
1819 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
1820 parameters.
1822 2005-07-10 Stepan Kasal <kasal@ucw.cz>
1824 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
1825 versions of Portland Group compiler produce single- and double-quoted
1826 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
1827 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
1829 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1831 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1832 This is a corrected version of yesterday's patch.
1834 2005-07-07 Stepan Kasal <kasal@ucw.cz>
1836 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
1837 path, too; insert a "===" to emphasize the line.
1839 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
1840 ac_cv_build_alias to ac_build_alias.
1841 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
1843 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
1844 change eliminates it. Problem reported by Alexandre Duret-Lutz.
1845 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
1846 (AC_ARG_VAR): ... here.
1847 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
1848 target_alias.
1850 Keep a list of all precious variables and process them with one simple
1851 for loop, instead of expanding all commands, or, OTOH, complicated
1852 processing of output of "set".
1853 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
1854 variable names in new macro...
1855 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
1856 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
1857 a loop to assign all ac_env_* and ac_cv_env_* variables.
1858 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
1859 to INIT_PREPARE.
1860 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign

1984 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
1985 addition.
1987 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2010 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2011 Don't worry about backslashes in srcdir; it can't happen now.

2040 (Special Shell Variables): Fix sed code this in the example.
2041 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2042 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2044 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

2054 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2055 * doc/autoconf.texi:
2056 Don't mention Solaris versions so much, if a
2057 problem is common to all extant versions of Solaris. Say "SunOS
2058 4" instead of "SunOS" for SunOS 4.
2059 (awk): Mention more of the limitations of traditional Awk.
2060 (cat): Don't talk about cat -v.

2093 quotes and backslashes. Patch from Derek Price.

2102 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2103 -u, since it outputs chatter if the input files are the same.
2104 Problem reported by Ralf Menzel.
2106 2005-06-08 Derek Price <derek@ximbiot.com>
2108 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2109 renaming them since they are about to be redefined anyhow.
2111 2005-06-08 Derek Price <derek@ximbiot.com>
2113 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2114 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2115 Move m4_undefine to alphabetical order.
2117 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

2120 * doc/autoconf.texi (Introduction): Likewise.
2121 Reword to avoid some formatting glitches.
2122 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

2124 Redo example output tp match current CVS snapshot.
2125 Use @example.org in email addresses when the examples
2126 might get inadvertently cut-and-pasted into user code.
2127 Remove example of autom4te usage that doesn't seem to work now.
2128 Use modern AC_INIT (except when the example is meant to be
2129 shown with Autoconf 2.13).
2130 Update ksh info for Solaris 9 and later.
2131 KB -> kB.
2132 Modernize description of Automake versions a bit.
2133 Don't claim a future version of Autoconf is near.

2140 Reword to avoid some formatting glitches.
2141 * doc/installt.exi: Reword to avoid some formatting glitches.
2143 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2144 Tru64 ksh pattern matching bug. Reported against Libtool by
2145 Albert Chin <libtool@mlists.thewrittenword.com> and
2146 Nicolas Joly <njoly@pasteur.fr>.
2148 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2150 m4_cdr of one-member list was [[]] (one-member list containing an
2151 empty string) instead of [] (an empty list. Callers were skewed to
2152 match this misbehaviour. As a consequence of this:
2153 - m4_foreach([x], [], [foo]) expanded to `foo', while
2154 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2155 This bug has been fixed:
2157 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2158 expand to an empty string; print error msg if called without
2159 an argument list.
2160 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2161 misbehaviour; handle [] and [[]] correctly.

2171 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2172 swallow records with more than 99 fields.
2173 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2174 parse the long line.
2176 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2178 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2179 swallow literals longer than 399. Reported by Ralf Wildenhues.

2191 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2192 (DISTCLEANFILES): Remove $(check_SCRIPTS).

2197 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2198 expression of unbounded size when processing the --list
2199 option. This runs afoul of a limit of 399 bytes per regular
2200 expression on AIX. Problem reported by Ralf Wildenhues.

2213 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2214 now contain newlines, and substituted files must be referenced on
2215 a line alone; the sed scripts to substitute them are now very
2216 different.

2218 commands can be put in a sed script portably.
2219 * doc/autoconf.texi (Setting Output Variables): Document above

2232 classes in shell scripts. The test was too brittle.
2234 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2236 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

2270 (ac_top_build_prefix): ... to this; the old name is also kept, for
2271 backward compatibility.
2272 (ac_top_builddir_sub): New variable, without the trailing slash,
2273 always nonempty.
2274 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

2288 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2289 argument to m4_foreach. I guess it was necessary in the past,
2290 but I think it's a no-op now.
2292 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2294 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2295 ``cat <<_ACEOF'' commands to one.

2355 check.
2356 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2357 enough arguments, similarly as in m4_bpatsubsts.

2366 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2367 for absolute directory names in one loop.
2368 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2369 abbreviations of --version and --debug.
2371 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2373 * doc/autoconf.texi (Autoconf Language): Be more precise about
2374 quoting rules. Problems noted by Stepan Kasal.
2375 Also, throughout this document, be more careful about white space.
2376 "blank", "white space", and "space" all have different meanings
2377 and we should be careful to say what we mean.
2379 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2381 Fix C++ related problems reported by Werner Lemberg.
2382 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2383 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2384 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2385 avoid problems with C++ and throw.
2386 * tests/compile.at: .cpp, not .cc.
2388 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2390 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2392 * doc/autoconf.texi (Generic Functions): Typos.
2394 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2396 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2397 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2398 set by latest automake.
2400 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2402 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2403 outputs 0 on GNU/Linux these days.
2405 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2407 * doc/autoconf.texi (Autoconf Language): Add more description
2408 about quoting heuristics.
2409 (Limitations of Builtins): Describe "set -" problems.
2411 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2413 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2414 not newline.
2416 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2417 by AC_DEFINE; it was a mistake.
2418 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2420 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2422 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2424 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2426 * doc/autoconf.texi (External Software): Quadrigraphs are not
2427 processed correctly in AS_HELP_STRING; avoid this in the examples.
2428 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2429 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2430 comment and reduce m4_default([foo], []) to [foo].
2431 (m4_strip): Update the explanation.
2433 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2435 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2436 Remove core.conftest.* too; it's generated by Tru64 5.1.
2437 Problem reported by Jennis Pruett.
2438 * lib/autoconf/functions.m4
2439 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2440 Don't bother to remove core files; AC_RUN_IFELSE should do that
2441 for you.
2443 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2445 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

2457 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
2459 * doc/autoconf.texi (External Software, Package Options): Add
2460 examples showing how to implement --with-* and --enable-* options.
2462 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2464 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2465 as well as configure.in. Problem reported by Gregorio Guidi.
2467 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2469 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2470 pattern for alloca snippet.

2480 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2482 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2483 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2485 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2487 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2488 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2489 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2490 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2491 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2493 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2495 * NEWS: The configure command now warns you if you attempt to use
2496 a directory whose name contains a special character like space,
2497 newline, or "\".
2498 * doc/autoconf.texi (Installation Directory Variables): Allow
2499 "," in file names. Do not use \@; it's not a portable regexp.
2500 * bin/Makefile.am (edit): Likewise.
2501 * lib/Makefile.am (edit): Likewise.
2502 * tests/Makefile.am (edit): Likewise.
2503 * tests/semantics.at: Likewise.
2504 * tests/torture.at: Likewise.
2505 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2506 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2507 * doc/autoconf.texi (File System Conventions): Warn about
2508 unportable file names.
2509 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2510 (AC_INIT): Use it.
2511 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2512 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2513 ac_pwd, and quote srcdir.
2514 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2516 * doc/autoconf.texi: Fix some systematic formatting problems.
2517 ".)" needs a following @: if not at the end of a sentence, and
2518 similarly for "!)". "etc." should be preceded by a comma.
2519 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2521 2005-03-22 Bruno Haible <bruno@clisp.org>
2523 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2524 argument is often called 'build-aux'.
2526 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2528 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2529 macro AC_TRY_LINK is obsolete.
2530 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2531 `AC_CONFIG_FILES'.
2533 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2535 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2536 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2537 from a Common Lisp's `cl'.
2538 (AC_PROG_CXX): Behave according to the documentation: don't
2539 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2540 make the variable CCC precious; use `cl.exe', not `cl'.
2542 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2543 Alexandre Duret-Lutz <adl@gnu.org>
2545 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2546 /dev/null, as "configure" shouldn't read stdin, and this insulates
2547 us from problems (e.g., when testing for "cl"). Also, do this
2548 redirection before invoking "hostname" or "uname", and keep the
2549 original input stream available via...
2550 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2551 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2552 bother with "</dev/null" since it's now done at the top of
2553 'configure'.
2554 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2555 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2556 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2557 * doc/autoconf.texi (File Descriptor Macros): New section.
2558 (Printing Messages): Mention it.
2559 * tests/base.at (Input/Output): New test.
2561 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2563 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2564 newline if neither \c nor -n work, as that would output two
2565 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2567 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2569 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2570 This causes that any required macros inside will get before the if.
2571 * doc/autoconf.texi (autom4te.cache): A typo.
2573 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2575 Undo previous change, except keep the change to
2576 lib/autoconf/programs.m4 that replaced grep with shell
2577 pattern-matching. This is because net-snmp configure reads stdin.
2578 Reported by Noah Misch.
2580 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2582 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2583 from /dev/null, as "configure" shouldn't read stdin, and this
2584 insulates us from problems (e.g., when testing for "cl").
2585 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2586 before invoking "hostname" or "uname".
2587 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2588 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2589 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2590 "</dev/null" since it's now done at the top of 'configure'.
2591 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2592 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2593 Also, replace grep with shell pattern-matching, to save a process.
2595 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2597 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2598 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2599 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2600 compiler.
2602 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2604 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2605 grep -q isn't portable. Improve grep -s explanation.
2606 Problem reported by Dan Manthey.
2608 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2610 * doc/autoconf.texi (Special Shell Variables): Clarify
2611 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2613 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2615 * doc/autoconf.texi: Use @acronym for DJGPP.
2616 Fix some @code's that should have been @env's, and vice versa.
2617 Sort environment variable names.
2618 Mention that shells no longer inherit IFS.
2619 Don't recommend PATH_SEPARATOR=';' so strongly.
2620 Mention that $RANDOM might expand to the empty string.
2621 "symlink" and "soft link" -> "symbolic link".
2622 Improve mktemp description (reported by Bruno Haible).
2624 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2626 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2627 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2628 Likewise.
2629 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2630 Likewise.
2632 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2634 * NEWS: Mention AT_COPYRIGHT.
2636 * tests/local.at (AT_CMP): Use diff directly on input files rather
2637 than copying them.
2639 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
2640 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
2642 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2643 and Paul Eggert <eggert@cs.ucla.edu>
2645 * tests/autotest.at (Empty test suite): New test.
2646 * tests/torture.at (Substitute and define special characters)
2647 (Substitute a 2000-byte string, Define to a 2000-byte string)
2648 (Substitute a newline, Define a newline): New tests.
2650 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2652 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
2653 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
2654 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
2655 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
2656 (Standard regular expressions): New test.
2657 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
2658 excess test name quoting.
2659 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
2660 CPPFLAGS to `configure' instead of setting it in `configure'.
2662 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
2663 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
2664 on some platforms.
2666 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
2667 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
2669 * tests/local.at (AT_CMP): New macro.
2670 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
2671 (AC_SAVE_STATE): Move environment grep...
2672 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
2673 (AT_CONFIG_CMP): New macro.
2674 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
2675 * tests/c.at (Extensions): Do not exit early.
2676 * tests/atlocal.in: Inherit $GREP.
2678 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
2679 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
2681 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
2682 (AC_COPYRIGHT): Factor header comment portion out and move into...
2683 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
2684 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
2685 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
2686 --version output.
2687 * tests/local.at: Add Autoconf test suite copyright notice.
2688 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
2690 2005-02-04 Bruno Haible <bruno@clisp.org>
2691 and Paul Eggert <eggert@cs.ucla.edu>
2693 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
2695 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
2697 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
2698 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2700 Try not to generated lines of unlimited length, as POSIX places a
2701 2047-byte limit on line length of portable text files.
2702 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2703 Use newline as a separator, not space.
2704 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
2705 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
2706 space.
2708 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2710 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
2711 as_func_*. Add test to check whether positional parameters
2712 are restored after function return.
2714 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
2716 * doc/autoconf.texi (Special Shell Variables): Mention _,
2717 BIN_SH, DUALCASE. Say that variables other than "status" are safe
2718 if they contain a lower-case letter. The DUALCASE problem was
2719 reported by Ralf Wildenhues.
2721 * bin/autoconf.as: Don't exit with status 0 after write failure
2722 with --help or --version.
2723 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
2724 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
2726 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2728 * doc/autoconf.texi (Limitations of Usual Tools):
2729 Unicos 9 sed limitations.
2730 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
2731 to get the option-enhanced interface on older Crays. Try ftn for
2732 Fortran 95 (newer Crays).
2734 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
2736 * man/Makefile.am (.x.1): Go back to the simple solution, but take
2737 care to echo the commands, so the user knows what's going on.
2738 Modified from a suggestion by Stepan Kasal.
2740 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
2741 with a cross reference. Derived from a suggestion by Bruce Korb.
2743 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
2745 * doc/autoconf.texi (config.status Invocation): Warn about
2746 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
2747 * doc/install.texi (Defining Variables): Likewise.
2748 Based on a proposed patch by Ralf Wildenhues.
2750 * man/Makefile.am (.x.1): Make sure the required generated files
2751 are up to date. Problem and original solution proposed by Stepan Kasal.

2761 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2762 Update the long comment explaining it.
2764 m4_require no longer writes an ``is required by'' line to the
2765 execution stack. It contains only one bit of non-redundant
2766 information: that the macro was required, not called. And even
2767 this bit is useless in most situations: have you ever met a macro
2768 which both calls and requires the same macro?
2770 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2771 (_m4_defun_pro_outer): ... only via this macro, for the outermost
2772 macro.

2778 (_m4_require_call): Use it.
2779 * tests/m4sugar.at (m4_require): Expect output without the
2780 ``is required by'' messages.
2782 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2784 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2785 rather than x for expr.
2787 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2788 this is safe.
2789 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2790 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2803 support.
2804 * bin/autoheader.in: Pass $force to update_file so that
2805 config.h.in is always recreated when --force.

2816 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2818 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2819 Warn about newline stripping in `` and $(). Update Solaris

2824 stripping.
2826 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2848 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2850 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

2875 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
2876 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
2877 stored in _m4_divert_diversion or _m4_divert_dump.
2878 (m4_divert_pop): When the parameter is given, compare the symbolic
2879 name with the last diversion pushed on the stack. Previously, the
2880 current diversion was compared with the numeric value of the
2881 diversion given as the parameter.
2882 (m4_require): If the macro hasn't been expanded yet, call ...
2883 (_m4_require_call): this new macro.

3097 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

3162 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

3165 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
3166 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
3167 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

3183 out the common code to ...
3184 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
3185 value of the #define--default to 1, iff the macro was called
3186 with exactly one parameter.
3188 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3190 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3191 "char c = '\200';" rather than "char c = 0x80;" as the
3192 latter doesn't conform to the strict C standard due to
3193 overflow on signed char hosts.
3195 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3196 to -qlanglvl=ansi. We don't want to disable extensions.

3255 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3257 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3258 the $1_found variable, don't test whether the file is executable;
3259 Both things are checked ...
3260 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3261 the former ``test -f''.
3262 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
3264 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

3295 * doc/autoconf.texi (auindex): New macro.
3296 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3297 Problem reported by Stepan Kasal.
3299 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3301 Fix problems reported by Andreas Buening in:
3302 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3303 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3304 in test makefile.
3305 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3306 readable; it's not true in OS/2-emx.
3308 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3310 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3311 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3312 (trivial change). Problem and patch reported by Andrew Church in:
3313 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3315 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

3320 Also, fix some minor spacing and punctuation bugs.
3322 2004-09-02 Akim Demaille <akim@epita.fr>
3324 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

3340 * README: Add advice about m4 1.4.2.
3342 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3343 texinfo.tex for now (done by hand now).
3344 * Makefile.maint (wget_files, cvs_files):
3345 Remove ansi2knr.c; nobody uses it.
3346 (ansi2knr.c-url_prefix): Remove.
3347 (cvs-update): Fix test for failure. I don't know why it ever
3348 worked...
3350 * doc/autoconf.texi: Update URLs, some of which went stale.
3351 Use @uref rather than @href.
3353 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3354 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3356 * config/config.guess, config/config.sub, config/elisp-comp,
3357 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3358 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3360 * NEWS, TODO, configure.ac, bin/autoscan.in,
3361 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3362 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3366 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3367 tests/tools.at, tests/torture.at:
3368 Use "file name" rather than "filename" or "path",
3369 to be consistent with the terminology of the GNU coding standards.
3371 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3373 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3374 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3375 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3376 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3378 More fixes to support spaces in the name of the build directory.
3379 This isn't a complete fix but it's an improvement.
3381 * bin/autoconf.as (autom4te_options): New var.
3382 Use it instead of appending to AUTOM4TE, so that we can allow
3383 spaces in the build directory's absolute name.
3384 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3385 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3386 AT_CHECK_NOESCAPE): Likewise.
3387 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3388 main program): Likewise.
3390 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3392 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
3393 From Ralf Corsepius in:
3394 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
3396 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3398 * doc/autoconf.texi (Function Portability): Document isinf and
3399 and isnan. From a suggestion by Kevin Ryde.
3401 * lib/Autom4te/General.pm (END): Return correct exit status even
3402 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3404 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3406 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3407 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3408 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3410 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3412 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3413 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3414 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3415 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3416 * lib/autom4te.in (Automake-preselections): Preselect
3417 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3419 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3421 * lib/autom4te.in (Automake-preselections): Preselect
3422 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3423 trace them.
3425 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3427 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3428 Tru64.
3429 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3430 Document problem with "`""`" in pdksh POSIX mode.
3432 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3434 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3435 with pdksh, too. Problem reported by Patrick Welche via
3436 Gary V. Vaughan.
3437 * doc/autoconf.texi (Shellology): Note that set -o posix is
3438 useful for pkdsh, too.
3440 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3442 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3443 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3444 Don't fail if ENV or BASH_ENV is readonly.
3445 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3446 etc. are read only. Problem reported by Ludovic Courtes.
3448 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3450 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3451 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3452 (trivial change)
3454 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3456 * doc/autoconf.texi (File System Conventions): Warn about
3457 names like "aux". Problem reported by Eric Blake.
3459 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3460 by zero instead of array size, so that we can use any arithmetic
3461 constant expression (instead of requiring an integer constant
3462 expression). This allows us to test expressions like DBL_MAX <
3463 LDBL_MAX, which didn't conform to the C standard using the old
3464 method.
3465 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3466 now that we can do floating-point tests at compile time.
3468 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3470 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3471 and LDBL_EPSILON, as the resulting expression isn't an
3472 integer constant expression and violates the C standard.
3473 Problem reported by Nelson H. F. Beebe. Also, check
3474 for "L" suffix, and check that long double doesn't have
3475 worse range or precision than double, that mixed-mode
3476 arithmetic doesn't generate a diagnostic, that double
3477 constants fit in long double.
3479 2004-06-03 Kevin Ryde <user42@zip.com.au>
3481 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3482 malloc(0) and realloc(NULL,size).
3484 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3485 Bob Proulx.
3487 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3489 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3490 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3491 by Jim Meyering.
3493 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3495 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3496 can be rewritten using if-then-else. Suggested by Bruno Haible.
3498 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3500 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3501 Problem reported by Stepan Kasal.
3503 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3505 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3506 change). Patch reported by Ralf Wildenhues in
3507 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3509 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3510 function F exists if the compiler and linker let you compile an
3511 expression like (F != 0). Recent versions of GCC optimize away
3512 the reference to F in that case, since every function address must
3513 be nonzero, so the link succeeds even if F does not exist.
3514 Problem reported by Manu in
3515 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3517 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3518 "Unix". Many uses changed.
3519 (Limitations of Builtins): Explain better why the ! command isn't
3520 portable.
3522 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3524 * lib/autom4te.in (Automake-preselections): Preselect
3525 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3527 2004-05-19 Kevin Ryde <user42@zip.com.au>
3529 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3530 referencing AC_FUNC_STRERROR_R.
3532 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3533 note pessimistic assumption when cross compiling.
3535 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3537 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3538 (until 2004) invoked subcommands with sh -e, contra POSIX.
3539 Reported by Kevin Ryde.
3541 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3543 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3544 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3545 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3546 `test -f " /usr/bin/grep"', which _always_ failed.
3547 (AC_PROG_SED): Ditto bogus PATH fix.
3548 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3549 requires that grep correctly supports _multiple_ `-e' options, rather
3550 than stating only that grep should accept `-e'.
3552 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3554 Port to C99, which requires that 'exit' be declared.
3556 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3557 to ensure that stdlib.h is included.
3558 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3559 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3560 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3561 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3562 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3563 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3564 when using 'exit' in a test; C99 requires that 'exit' be declared.
3566 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3568 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3569 now prefers 'grep' implementations that accept -e.
3570 (Limitations of Usual Tools): Describe problems of traditional
3571 egrep and fgrep with long input lines, and of traditional grep
3572 with -e.
3573 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3574 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3575 All callers changed. Append /usr/xpg4/bin to the PATH, for
3576 Solaris.
3577 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3578 the user with complaints about multiple -e options.
3579 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3580 Define it with AC_PROG_GREP.
3581 * configure.ac (AC_PROG_GREP): Add.
3582 * lib/freeze.mk (GREP): New macro.
3584 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3586 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3587 a possible candidate only after all others fail, rather than
3588 consulting it first. This improves backward compatibility by
3589 better reflecting the way shell selection occurred in previous
3590 versions of Autoconf, and should help to avoid triggering latent
3591 problems in other packages, such as the one in Automake where zsh
3592 is not handled robustly:
3593 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3594 Although it is not Autoconf's responsibility to work around
3595 problems in Automake, it nevertheless makes sense to avoid
3596 introducing unnecessary incompatibilites.
3598 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3599 Gary V. Vaughan <gary@gnu.org>
3601 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3602 how deeply nested we are when a suitable tool is found, set the
3603 ac_path_TOOL_found flag.
3604 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3605 nested we are in this macro. Break out of all 3 nested loops if
3606 ac_path_TOOL_found is set.
3608 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3610 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3611 of the _AS_PATH_WALK loop too if GNU flavor is found.
3613 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3615 * doc/autoconf.texi (Limitations of Make): Update documentation
3616 for `$<'. New entry `Long lines', based on a report from Simon
3617 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3618 paragraph about DJGPP, based on a mail from Richard Dawe.
3620 2004-04-20 Paul Eggert <eggert@twinsun.com>
3622 * tests/c.at (C keywords): Don't assume that GCC supports
3623 "restrict" and "inline", as sufficiently-old GCC versions do not
3624 (also, GCC configured to be in pedantic C89 mode does not).
3625 Problem reported by Sumit Pandya in:
3626 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3628 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3629 consider -g to work if it generates warnings when plain compiles
3630 don't. Problem reported by Braden McDaniel in:
3631 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3633 * doc/autoconf.texi (Slashes): New section, to document a problem
3634 reported by Jim Meyering in:
3635 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3637 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3638 linker output files before linking, to work around IRIX 6 linker bug.
3639 Problem reported by Rainer Orth in:
3640 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3642 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3644 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3645 best tool so far counter rely on the tool path variable name to
3646 avoid checks for one tool being affected by the results of running
3647 the length check on a previous tool.
3649 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3650 match expression argument, as different greps have different
3651 regular expression flavours.
3652 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3653 literals.
3654 (AC_PROG_EGREP): Pass 'EGREP$'.
3655 (AC_PROG_GREP): Pass 'GREP$'.
3657 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3659 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3660 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

3664 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3665 Types, Specific Compiler Characteristics, System Services,
3666 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3667 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3668 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3669 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

3682 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3683 now defines HAVE_DECL_TZNAME if it is declared, when
3684 HAVE_STRUCT_TM_TM_ZONE is not defined.
3685 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3686 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

3735 new macros.
3736 * NEWS: Document these changes.
3738 * doc/autoconf.texi: Avoid macros with unbraced arguments,

3744 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3745 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

3767 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3769 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

3772 2004-02-18 Paul Eggert <eggert@twinsun.com>
3774 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3775 problem on QNX reported by Stephen Rasku in
3776 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3778 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

3787 AC_SUBST provides no portable way to escape literal newlines.
3789 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3790 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3791 Darwin uses -lcrt2.o and there's little point to cataloging all
3792 the system variants. Partial fix reported by Andreas Waechter in:
3793 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
3794 for bug reported by Nelson H. F. Beebe in:

3817 Eric Sunshine <sunshine@sunshineco.com>
3818 Paul Eggert <eggert@twinsun.com>
3820 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

3824 (_AS_SHELL_FN_SPY): New macro.
3825 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3826 macros.
3827 (AS_SHELL_SANITIZE): Remove loop to find better shell
3828 and documentation for the parameter.

3832 (AS_REQUIRE_SHELL_FN): Require shell functions when
3833 it is used.
3834 (_AS_LINENO_WORKS): Put around braces, we do not
3835 trigger the bash bug anymore.
3836 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3837 use AS_INIT_WITH_SHELL_FN.
3838 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3840 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

3846 (AU_DEFUN): Honor the third parameter, create autoupdate
3847 macros with AU_DEFINE.
3848 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
3849 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

3868 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
3869 2003 (except 1997) to the list of copyright years. This undoes
3870 the 2003-05-22 change, which removed the older years from the list.
3871 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
3873 2004-01-27 Gary V. Vaughan <gary@gnu.org>

3885 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
3886 longest input length accepted by a command.
3887 (AC_PROG_SED): Use it.
3888 * doc/autoconf.texi (Particular Programs): Document the changes.
3889 * NEWS: Updated.
3891 2004-01-27 Paul Eggert <eggert@twinsun.com>

3898 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
3899 bin/autoconf.in, config/Makefile.in, config/config.guess,

3913 sources.
3915 2004-01-26 Paul Eggert <eggert@twinsun.com>
3917 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
3918 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
3919 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
3920 not <inttypes.h>. Problem reported by Tim Mooney in
3921 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
3922 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
3923 Likewise.
3925 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
3926 otherwise "make check" fails because it forbids cmp (I guess
3927 because cmp treats files as binary on DOS-like systems).
3929 * tests/mktests.sh: Update copyright date to 2004, since some tests
3930 have changed in 2004.
3932 2004-01-23 Gary V. Vaughan <gary@gnu.org>

3935 non-truncating sed or gsed program in PATH.
3936 * tests/acprograms.at: Add it.
3937 * doc/autoconf.texi (Particular Programs): Document it.
3938 * NEWS: Updated.
3940 2004-01-15 Paul Eggert <eggert@twinsun.com>
3942 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
3943 -std1 disables some useful extensions on Tru64. Problem reported
3944 by N. Lichtmaier in
3945 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
3947 2004-01-14 Paul Eggert <eggert@twinsun.com>
3949 * doc/autoconf.texi (Programming in M4sh): Document that
3950 AS_MKDIR_P succeeds if the destination is a symbolic link
3951 to an existing directory.
3952 (Limitations of Usual Tools): Note that mkdir -p might not
3953 succeed on symlinks to directories.
3955 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
3957 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
3958 * bin/autoheader.in: Grammar fix in message.
3959 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
3960 Test for dir before calling mkdir -p. (trivial changes)
3962 2004-01-13 Eric Blake <ebb9@byu.net>
3964 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
3965 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
3967 2004-01-10 Jim Meyering <jim@meyering.net>
3969 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
3971 2004-01-09 Paul Eggert <eggert@twinsun.com>
3973 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
3974 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
3975 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
3976 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
3977 AC_COMPILE_IFELSE, since we now assume our caller invokes
3978 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
3979 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
3980 of AC_RUN_IFELSE; this avoids the warning mentioned above.
3981 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
3983 2004-01-07 Paul Eggert <eggert@twinsun.com>
3985 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
3986 `"'...'"`, as it's confusing (and I suspect it may not work on
3987 some platforms). The code was incorrect anyway, as it assumed
3988 that \$ evaluated to itself in that context. Reported by
3989 Alexandre Duret-Lutz.
3991 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
3993 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
3994 and _LT_AC_TAGCONFIG.
3996 2004-01-06 Paul Eggert <eggert@twinsun.com>
3998 * doc/autoconf.texi (One Macro Call): Fix an incorrect
3999 example, and add more examples. Reported by Eric Sunshine.
4001 2004-01-05 Paul Eggert <eggert@twinsun.com>
4003 * doc/autoconf.texi (Limitations of Usual Tools):
4004 Remove warning against "rm -fr" introduced yesterday; it
4005 was a false alarm.
4007 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4008 autoscan, autoupdate, ifnames): Don't use chmod -w.
4009 * lib/Makefile.am (autom4te.cfg): Likewise.
4010 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4011 "chmod -w".
4013 2004-01-04 Paul Eggert <eggert@twinsun.com>
4014 Paolo Bonzini <bonzini@gnu.org>
4016 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4017 by doing lineno substitution only on lines containing "$LINENO".
4019 2004-01-04 Paul Eggert <eggert@twinsun.com>
4021 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4022 Use "rm -f" to remove conftest.sed, not plain "rm".
4023 Bug reported by David Relson in
4024 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4026 * Makefile.am (autom4te-update):
4027 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4028 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4029 * doc/autoconf.texi (Guidelines): Likewise.
4030 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4036 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4037 srcdir): Likewise.
4038 * doc/autoconf.texi (Limitations of Usual Tools):
4039 Warn against "rm -fr".
4041 2004-01-03 Paul Eggert <eggert@twinsun.com>
4043 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4044 -c -o might not work. From a suggestion by Kevin Ryde.
4045 (C Compiler, Generating Sources, Limitations
4046 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4047 Don't put '-o' after non-options, as POSIX doesn't allow this.
4048 Mention that cc's name might be gcc or c89 or whatever.
4050 2004-01-04 Kevin Ryde <user42@zip.com.au>
4052 * doc/autoconf.texi: Add various further index entries.
4054 2003-12-29 Paul Eggert <eggert@twinsun.com>
4056 * bin/autoreconf.in (autoreconf_current_directory):
4057 Fix typo: mkdir without umask arg.
4059 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4061 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4062 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4063 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4064 explanation clearer.
4066 2003-12-24 Andreas Schwab <schwab@suse.de>
4068 * doc/autoconf.texi (Default Includes): Fix misspelling of
4069 AC_INCLUDES_DEFAULT.

4073 * configure.ac: Test if sh -n works.
4074 * configure: Regenerate.
4075 * tests/atlocal.in: Store the result here.
4076 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4077 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4078 of explicitly testing.
4079 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4080 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4081 * tests/tools.at (Syntax of the shell scripts): Simplify
4082 using AT_CHECK_SHELL_SYNTAX.
4083 (Syntax of the Perl scripts): Remove definition of
4084 AT_CHECK_PERL_SYNTAX.
4086 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4088 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
4089 stderr to /dev/null.

4123 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4327 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
4328 cross test.
4330 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
4332 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

4349 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

4374 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4375 cache variable instead of $G77 to decide whether to include -O2,
4376 since $G77 is specific to Fortran 77.

4380 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

4385 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4386 arguments so that it can be used with syntax identical to
4387 AC_PROG_F77, and so that we can more easily decide to
4388 remove/deprecate the DIALECT optional argument in the future if it
4389 proves troublesome.
4390 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4391 non-freeform-supporting compilers. Document freeform flags.
4393 2003-10-03 Akim Demaille <akim@epita.fr>
4395 * configure.ac: Look for emacs, not macs.

4405 2003-10-03 Akim Demaille <akim@epita.fr>
4407 * configure.ac: Quotation and formatting changes.

4460 2003-09-26 Akim Demaille <akim@epita.fr>
4462 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4463 directory for AC_CONFIG_COMMANDS' first argument exists.
4464 This makes valid the invocation of _AC_SRCPATH that follows.
4465 Reported by Eric Sunshine.
4466 * doc/autoconf.texi (Configuration Commands): Adjust.
4468 2003-09-26 Akim Demaille <akim@epita.fr>
4470 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4471 Reported by Ralf Corsepius.

4475 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4476 arguments.

4487 2003-09-26 Akim Demaille <akim@epita.fr>
4489 The test suite are sometimes assigning timings incorrectly.
4490 Reported by Henk Krus.
4491 Diagnosed by Nicolas Joly.
4493 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4494 AT_help_all.
4495 Instead of making AT_help a sequence of assignments to grow
4496 $at_help_all, just make AT_help_all be the growing contents of
4497 $at_help_all, and make a single assignment in...
4498 (AT_INIT): here.
4499 (at_times_skip): Flip the meaning and rename as...
4500 (at_times_p): this.
4501 (AT_INIT): When summarizing the test that ran, remove

4511 (ifnames): chmod -w.
4512 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4513 executables, not bin/ executables! Otherwise all the magic needed
4514 to find non installed files is turned off. This caused a failure
4515 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4516 as found in its environment (sent by tests/autoreconf): pointing
4517 to bin/autom4te that could not find its files.
4518 * tests/mktests.sh: Force the replacement of generated files, for
4519 the sake of "mv" program that are interactive when overwriting a
4520 -w file.

4562 From Peter Hendrickson.
4564 2003-09-10 Akim Demaille <akim@epita.fr>
4566 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4567 willing to edit the output files.
4569 2003-09-10 Akim Demaille <akim@epita.fr>
4571 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4572 and AC_FC_FREEFORM.
4573 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4574 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

4596 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4597 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4599 2003-09-04 Akim Demaille <akim@epita.fr>
4601 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4602 AC_FUNC_WAIT3.
4604 2003-09-04 Akim Demaille <akim@epita.fr>
4606 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4607 (freeze): When exiting, use $exit_code.
4608 * lib/autoconf/fortran.m4: Comment changes.
4610 2003-09-04 Akim Demaille <akim@epita.fr>
4612 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
4614 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4616 Add support for newer Fortran dialects. The F77 interface is
4617 unchanged, and continues to support Fortran 77. New FC macros
4618 correspond to all the old F77 macros, with output variables FC,
4619 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4620 available dialect, but older dialects can be specified. There are
4621 new macros AC_FC_SRCEXT to set the source extension, and
4622 AC_FC_FREEFORM to accept free-form source files.
4624 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4625 New macros.
4626 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
4627 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
4628 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
4629 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),
4630 AC_LANG_PROGRAM(Fortran), AC_LANG_CALL(Fortran),
4631 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),

4635 _AC_FC_LIBRARY_LDFLAGS, AC_FC_LIBRARY_LDFLAGS, _AC_FC_DUMMY_MAIN,
4636 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
4637 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
4638 AC_FC_SRCEXT, AC_FC_FREEFORM):
4639 New macros.
4640 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
4641 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
4642 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
4643 Rewrite in terms of the above.
4644 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
4645 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
4646 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
4647 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
4649 2003-09-02 Paul Eggert <eggert@twinsun.com>
4651 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
4652 Document problems with timestamp resolution that 'make', 'cp -p', and
4653 'touch -r' have.
4655 2003-08-27 Akim Demaille <akim@epita.fr>
4657 * tests/m4sugar.at (cross_warning): Make sure to enable the
4658 output, so that we can track spurious m4sugar output.
4659 * tests/local.at: Require 2.57.
4660 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4661 are defaulted by AT_CHECK anyway.
4662 Use AT_CHECK_AUTOM4TE.
4663 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4664 missing dnl.
4666 2003-08-27 Akim Demaille <akim@epita.fr>
4668 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4669 when -Wobsolete is set.
4670 Set it on by default.
4671 Suggested by Klee Dienes.
4673 2003-08-27 Akim Demaille <akim@epita.fr>
4675 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
4676 documentation.
4677 From Guido Draheim.
4679 2003-08-26 Akim Demaille <akim@epita.fr>
4681 * doc/autoconf.texi (Output): Make clear that one can run code
4682 after AC_OUTPUT.
4684 2003-08-25 Akim Demaille <akim@epita.fr>
4686 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
4687 CVS Bison.
4689 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
4691 * bin/autoreconf.in (parse_args): Do not pass --no-force to

4696 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.
4697 From Ville Karaila.

4703 2003-08-22 Akim Demaille <akim@epita.fr>
4705 Version 2.57b.
4707 * Makefile.cfg (local-checks-to-skip): New.
4708 * Makefile.maint (local-check): Rename as...
4709 (local-checks-available): this.

4712 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
4713 * configure.ac: Require Automake 1.7.6.
4715 2003-08-22 Akim Demaille <akim@epita.fr>
4717 Output stack traces in warnings.
4719 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
4720 Replace the former...
4721 (m4_warn): Pass the call stack to _m4_warn.
4722 * bin/autom4te.in: Adjust to output the call stack.
4723 * tests/m4sugar.at (m4@&t@_warn): Adjust.
4725 2003-08-22 Akim Demaille <akim@epita.fr>
4727 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
4728 * bin/autom4te.in: Adjust.
4730 2003-08-21 Akim Demaille <akim@epita.fr>
4732 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
4733 (&verbose): Remove.
4734 (&getopt): Adjust the note and verb channels, depending upon
4735 --verbose.
4736 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
4737 * bin/autoupdate.in: Adjust.
4738 Use &verb, not &verbose.
4740 2003-08-21 Akim Demaille <akim@epita.fr>
4742 * bin/autoheader.in (&parse_args): Use &parse_warnings and
4743 &parse_WARNINGS.
4744 ($help): Use Autom4te::ChannelDefs::usage.
4745 * bin/autoscan.in: Use Autom4te::ChannelDefs.
4746 * lib/Autom4te/General.pm: Don't export error: you don't own it.
4748 2003-08-21 Akim Demaille <akim@epita.fr>
4750 First stab at preserving warnings between calls to autom4te,
4751 including when the cache is used.
4753 There are still several issues: (i) there are too many runs of m4
4754 (one for include, one for warnings, and some more), (ii) warnings
4755 spreading on several lines are not handled gracefully, (iii) the
4756 code meant to have the call stack display for errors does not work
4757 (its handling should move from m4 to autom4te).
4759 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4760 Use them.
4761 (@preselect): Add m4_warn.
4762 ($exit_status): Remove, use $exit_code.
4763 ($help): Use Autom4te::ChannelDefs::usage.
4764 (&handle_m4): No longer define the m4_warnings.
4765 At each run, extract and report the warnings.
4766 Always cache the result, including if the exit status is on
4767 failure, since if nothing changes, we should result in the same
4768 failure, hence we can use the cache.
4769 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4770 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4771 Remove.
4772 (m4_warn): Redefine as a do-nothing: it is its invocation that
4773 matters, as warnings are now reported via traces.
4774 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4775 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4776 the latter reveals calls to the former.
4778 Adjust the tests.
4780 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4782 2003-08-21 Akim Demaille <akim@epita.fr>
4784 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
4785 Use them.
4787 2003-08-21 Akim Demaille <akim@epita.fr>
4789 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4790 forward order.
4791 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4792 (&parse_warnings): Accept a list of warning requests.
4793 (&usage): Return a string, not a side effect.
4794 (cross): New warning category.
4796 2003-08-21 Akim Demaille <akim@epita.fr>
4798 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4799 (&require_configure_ac): Accept an optional directory argument.
4800 ($configure_ac): Remove.
4801 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4802 (&catfile): Remove.
4803 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4804 * bin/autoscan.in: Adjust.
4806 2003-08-20 Akim Demaille <akim@epita.fr>
4808 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4809 Reported by Alexandre Duret-Lutz.
4811 2003-08-20 Akim Demaille <akim@epita.fr>
4813 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4814 * bin/autom4te: Adjust.
4815 In particular, be Autoconf tools are really silent when properly
4816 working, bind the verbosity of the 'note' channel to $verbose.
4817 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4818 (&xsystem, &contents): Remove, since they are exported by...
4819 * lib/Autom4te/FileUtils.pm: this.
4820 More perldoc.
4821 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4822 * lib/Autom4te/FileUtils.pm: here.
4824 2003-08-20 Akim Demaille <akim@epita.fr>
4826 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
4827 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
4828 from CVS Automake.
4830 2003-08-20 Akim Demaille <akim@epita.fr>
4832 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
4833 (autom4te-update): New.
4834 * Makefile.cfg (update): Bind autom4te-update.
4836 2003-08-19 Derek Price <derek@ximbiot.com>
4838 * lib/autotest/general.m4: Comment various HELP_* diversions.
4839 (PARSE_ARGS_BEGIN): New section for option parsing related
4840 initialization.

4850 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4852 * lib/autom4te.in (Automake-preselections): Preselect
4853 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
4854 and m4_sinclude.
4856 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4858 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

4860 * doc/autoconf.texi (autom4te Invocation): Mention
4861 Autoconf-without-aclocal-m4.

4877 2003-08-14 Derek Price <derek@ximbiot.com>
4879 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4880 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4881 shorter column three. Add DESCRIPTION to log file content.
4883 2003-08-13 Derek Price <derek@ximbiot.com>
4885 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
4886 output.
4888 2003-08-12 Derek Price <derek@ximbiot.com>
4890 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
4891 (AT_CHECK_NOESCAPE): Move core functionality to...
4892 (_AT_CHECK): ...this new macro.
4894 2003-08-07 Derek Price <derek@ximbiot.com>
4896 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
4897 (AT_CHECK_NOESCAPE): ...to this new macro.
4899 2003-07-31 Paul Eggert <eggert@twinsun.com>
4901 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
4902 in Bash 2.01. Problem reported by Brian Gough in
4903 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
4905 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
4907 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
4908 -lcrt1.o, for OS X. (trivial change)

4912 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
4913 inside '#ifndef __cplusplus'. Problem reported by
4914 Bob Friesenhahn.
4916 2003-07-06 Bill Clarke <llib@computer.org>
4918 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
4919 'long', not 'int', for benefit of Sun's recent C++ compilers
4920 (trivial change). See:
4921 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
4922 (This really should be 'intptr_t', not 'long', but that would
4923 take more work.)
4925 2003-06-25 Akim Demaille <akim@epita.fr>
4927 * lib/Makefile.am (autom4te.cfg): Make it read only.
4928 Depend on Makefile since it contains substitutions.
4929 From Paolo Bonzini.
4930 * lib/autom4te.in (args): Add local.at? for Autotest args.
4931 This change was made on autom4te.cfg which is generated.
4932 Reported by Raja R. Harinath.
4934 2003-06-25 Akim Demaille <akim@epita.fr>
4936 * doc/autoconf.texi (Header Portability): sys/mount.h.
4937 From Gareth McCaughan.
4939 2003-06-23 Akim Demaille <akim@epita.fr>
4941 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
4942 not all of them. This fixes 1. the fact that when testing
4943 Autoconf there are many many config.log, 2. the incorrect use of
4944 top_srcdir to find config.log.
4945 Don't mix the detailed output of failed test with the summary of
4946 failures. Rather, append detailed log afterwards.
4948 2003-06-23 Akim Demaille <akim@epita.fr>
4950 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
4951 always run: output config.log on $at_group_log.
4953 2003-06-23 Akim Demaille <akim@epita.fr>
4955 * tests/torture.at (#define header templates): Don't use quotes in
4956 C++ comments as it puzzles Emacs' sh font-lock-mode.
4958 2003-06-23 Akim Demaille <akim@epita.fr>
4960 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
4961 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
4962 * tests/atspecific.m4: Rename as...

4964 * tests/suite.at: Move the globals into...
4965 * tests/local.at: here.
4966 * tests/Makefile.am: Adjust.
4967 * doc/autoconf.texi (testsuite Scripts): Adjust.
4969 2003-06-21 Kevin Ryde <user42@zip.com.au>
4971 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
4972 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
4973 ensuring we add -std1 for full-ANSI.
4975 * doc/autoconf.texi (hdrindex): New macro.
4976 Add index entries for portability of various standard header files.
4978 2003-06-20 Akim Demaille <akim@epita.fr>
4980 * configure.ac: Bump to 2.57b.
4982 2003-06-20 Akim Demaille <akim@epita.fr>
4984 Version 2.57a.
4986 2003-06-20 Akim Demaille <akim@epita.fr>
4988 * bin/autom4te.in: Don't rely on $HOME being defined.
4989 Reported by Marc Espie as PR/233.
4991 2003-06-20 Akim Demaille <akim@epita.fr>
4993 * lib/autotest/general.m4: Use at_times_file only if used.
4994 From Nicolas Joly.
4996 2003-06-20 Akim Demaille <akim@epita.fr>
4998 * config/config.guess, config/config.sub, config/elisp-comp,
4999 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5000 Update from masters.
5002 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5004 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5005 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5006 (TEST_SCRIPT): New diversion.
5007 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5008 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5009 (AT_INIT): Support for expected failures.
5011 2003-06-02 Akim Demaille <akim@epita.fr>
5013 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5014 changes.
5015 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5016 Autoconf nor Automake.
5017 (&contents): New, from Automake.
5018 PODify.
5020 2003-05-28 Paul Eggert <eggert@twinsun.com>
5022 * NEWS, doc/autoconf.texi (Particular Functions),
5023 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5024 is the inverse of localtime.
5026 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5028 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5029 (handle_exec_errors): New function. Work around $! being
5030 altered by WEXITSTATUS.
5031 (xqx, xsystem): Use handle_exec_errors.
5033 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5035 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5036 Do not call `_exit()', simply modify `$?'.
5037 (xsystem): Reset $! before running system, and check it afterward.
5038 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5039 63 for version mismatches.
5041 2003-05-23 Akim Demaille <akim@epita.fr>
5043 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5044 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5045 the middle of a line).
5046 * lib/m4sugar/m4sugar.m4: Likewise.
5047 Remove useless spaces in comments.
5049 2003-05-23 Akim Demaille <akim@epita.fr>
5051 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5052 exit 63, so that we (or Automake's "missing") can tell the
5053 difference with a plain failure.
5054 * doc/autoconf.texi (Notices): Adjust.
5056 2003-05-23 Akim Demaille <akim@epita.fr>
5058 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5059 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5060 White spaces cleanup.
5062 2003-05-22 Jim Meyering <jim@meyering.net>
5063 Paul Eggert <eggert@twinsun.com>
5065 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5066 Remove `#include <stdlib.h>' from the list; we should never
5067 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5068 resulting namespace pollution would cause other tests to fail.
5069 Configure scripts run with some older versions of g++ and HP's
5070 aCC would fail due to such an #include. Problems reported by
5071 Matthew Mueller in <http://bugs.debian.org/120704> and by
5072 Keith Bostic in
5073 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5074 In the test, use the test declaration before including <stdlib.h>,
5075 as that's closer to how it'll be used.
5077 2003-05-23 Akim Demaille <akim@epita.fr>
5079 * doc/autoconf.texi (Header Portability): ucred.h.
5080 From Ian Redfern.
5082 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5084 Overhaul Autotest's logging: generate separate log files
5085 in testsuite.dir/NNN/testsuite.log, and append them to
5086 testsuite.log instead of re-running the test verbosely.
5088 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5089 file descriptor, write 0 to at_status_file instead of setting
5090 at_status=0, initialize some new variables (at_status_file,
5091 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5092 to rerun the tests, instead append the at_group_log to the
5093 at_suite_log when a test fails.
5094 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5095 with the AS_MESSAGE_LOG_FD redirected to stdout.
5096 (AT_CLEANUP): save the output status in $at_status_file
5097 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5098 its original place.
5099 (AT_CHECK): since tests are run with a redirected stdout,
5100 and used to be re-run in verbose mode, turn some $at_verbose
5101 into echo, and don't redirect the output of testing stdout
5102 and stderr.
5104 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5105 the name of the debugging directory and information about
5106 its contents.
5108 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5110 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

5223 and truncate.
5225 2003-05-06 Akim Demaille <akim@epita.fr>
5227 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5228 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5229 by aclocal.m4 is changed it might require the importing of another
5230 m4 extension file, i.e., aclocal must be run.
5232 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5233 (&parse_args): Use --force with aclocal if required and supported.

5241 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5242 argument instead of a file name, so that the request file remains
5243 open during the whole autom4te run.
5244 ($icache_file): New.
5245 (&freeze): Lock the $icache_file.
5247 2003-04-29 Derek Price <derek@ximbiot.com>
5249 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5250 seperator with m4_append_uniq(). It doesn't work.
5251 (AT_CLEANUP): Add `;' to end of at_help_all.
5252 (AT_INIT): Allow --keywords to be specified more than once. When
5253 grepping $at_help_all for keywords, use the field and keyword
5254 seperators to ensure a complete keyword match. Alter at_prev handling
5255 to support the new --keywords behavior.
5257 2003-04-27 Karl Berry <karl@freefriends.org>
5259 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5260 align better with others. I also made some of the individual
5261 entries on one line, for brevity and to make it easier for me to
5262 sort my dir-example file in the Texinfo distribution :).
5264 2003-04-12 Jim Meyering <jim@meyering.net>

5482 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5483 innocuous variant befor including <limits.h> or <assert.h>. This
5484 works around a bug reported by Albert Chin: HP-UX 11i
5485 (and earlier versions) have a <limits.h> that declares
5486 gettimeofday and many other functions.
5488 2002-12-03 Paul Eggert <eggert@twinsun.com>

5499 Martin Frydl in
5500 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5502 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5503 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5504 defined, to support freestanding compilers. This should fix the
5505 bug reported by Momchil Velkov in
5506 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5508 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5509 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

5514 * Makefile.maint (www-gnu): New macro.
5515 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
5516 the location has moved.
5518 2002-12-02 Martin Frydl <martin@systinet.com>
5520 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5521 \(.*\) match is too long and there is something more to be checked.
5522 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

5542 2002-11-14 Akim Demaille <akim@epita.fr>
5544 * Makefile.maint: Sync with Bison, i.e.:
5545 (po-check): Scan .l and .y files instead of the
5546 .c and the .h files that they generate. This fixes the bug
5547 reported by Tim Van Holder in:
5548 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5549 Look for N_ as well as for _. Try to avoid matching #define for
5550 N_ and _.
5551 From Paul Eggert.

5570 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5571 option. Process --recheck after parsing all options. Pass -q
5572 option to configure on --recheck.
5573 (AC_OUTPUT): Pass -q from configure to config.status.

5575 arguments to record.
5576 * doc/autoconf.texi (config.status Invocation): Document
5577 config.status -q option.
5579 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

5604 Reported by Ezra Peisach.
5606 2002-11-05 Akim Demaille <akim@epita.fr>
5608 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5609 Remove.
5610 We _have_ to stop using the old compatibility scheme that tried to
5611 avoid useless backslashes because Libtool 1.4.3 contains a
5612 AC_DEFINE([error_t], [int],
5613 [Define to a type to use for \`error_t' if it is not
5614 otherwise available.])
5615 We _have_ to quote the single quote and backslashes with \. The
5616 old compatibility scheme saw that ` was backslashed, and therefore
5617 did not quote the single quote. Hence before this patch, Autoconf
5618 was not compatible with Libtool.

5692 Problem reported by Bruno Haible.
5694 2002-10-29 Akim Demaille <akim@epita.fr>
5696 * doc/autoconf.texi (Header Templates): Put also in words what the

6008 longer required can still cause errors.
6009 Reported by Alexandre Duret-Lutz.
6011 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

6052 numbers in the Subject suggestion.
6054 2002-10-11 Akim Demaille <akim@epita.fr>
6056 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
6057 Suggest using AC_CHECK_DECLS instead.
6059 2002-10-11 Akim Demaille <akim@epita.fr>
6061 * tests/torture.at (AC_ARG_VAR): Have configure report the value
6062 of `precious'.
6064 2002-10-11 Akim Demaille <akim@epita.fr>
6066 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6067 file name to enable parallel executions.
6068 From Sam Varshavchik.
6070 2002-10-08 Akim Demaille <akim@epita.fr>
6072 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6073 aclocal invocation, as Gettext macros might not be visible to
6074 aclocal.
6075 Instead of blindly running autopoint, scan configure.ac (not the
6076 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6077 Reported by Paul D. Smith.
6079 2002-10-08 Paul Eggert <eggert@twinsun.com>
6081 Work around problems found when POSIXLY_CORRECT=1 is set.
6082 None of this seems to have anything to do with POSIX, really,
6083 but it's how Perl getopt works.
6084 * bin/autom4te.in (parse_args): Configure GetOpt with
6085 "permute", too.
6086 * doc/autoconf.texi (Invoking autom4te):
6087 --warning -> --warnings.
6088 * lib/autom4te.in: --warning -> --warnings.
6090 2002-09-28 Akim Demaille <akim@epita.fr>
6092 * doc/autoconf.texi (autom4te.cache): New section.
6094 2002-09-28 Akim Demaille <akim@epita.fr>
6096 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
6097 (Automake-preselections): Update.
6098 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
6100 2002-09-28 Akim Demaille <akim@epita.fr>
6102 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
6103 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
6104 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
6105 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
6107 2002-09-28 Akim Demaille <akim@epita.fr>
6109 * tests/torture.at (Configuring subdirectories): Be robust to
6110 users who use config.site to require for a cache: in this case,
6111 the two last configure runs, using two different sets of
6112 arguments, trigger a legitimate error.
6114 2002-09-28 Akim Demaille <akim@epita.fr>
6116 * tests/m4sh.at (Functions Support, Functions and return Support):
6117 New.
6119 2002-09-28 Akim Demaille <akim@epita.fr>
6121 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
6122 autoheader are Perl programs.
6123 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
6124 (autom4te): Specify that the sources are in the $srcdir.
6125 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6127 2002-09-28 Akim Demaille <akim@epita.fr>
6129 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
6130 (tm_zone): Move their rules to...
6131 * lib/autoconf/types.m4: here, using AN_ macros.
6132 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6133 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6134 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6135 * lib/autoconf/programs.m4: here.
6136 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
6137 (ETAGS_FOR_AUTOCONF): New.
6138 Use it.
6140 2002-09-28 Akim Demaille <akim@epita.fr>
6142 * lib/autoconf/autoscan.m4: New file.
6143 * lib/autoconf/autoconf.m4: Include it.
6144 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
6145 that were listed in the original autoscan.list.
6146 * lib/autoconf/headers.m4: Similarly with headers.
6147 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6148 (.m4.m4f): Don't pass --prepend-include, since that's done by
6149 tests/autom4te itself.
6150 * lib/autoscan/Makefile.am: Include freeze.mk.
6151 (autoscan.list): New target --this file is no longer a source.
6152 (autoscan.pre): New file.
6154 2002-09-28 Akim Demaille <akim@epita.fr>
6156 * bin/autoscan.in (@kinds): Make them singular.
6157 Adjust all uses.
6158 (&init_tables): When --debug, report the list of rules to ease
6159 tracking changes in autoscan.list.
6160 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6162 2002-09-28 Akim Demaille <akim@epita.fr>
6164 * lib/autoscan/functions, lib/autoscan/headers,
6165 * lib/autoscan/identifiers, lib/autoscan/makevars,
6166 * lib/autoscan/programs: Merge into...
6167 * lib/autoscan/autoscan.list: this.
6168 * bin/autoscan.in (&init_tables): Adjust.
6170 2002-09-28 Akim Demaille <akim@epita.fr>
6172 * lib/autoscan/functions, lib/autoscan/headers,
6173 * lib/autoscan/identifiers, lib/autoscan/makevars,
6174 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6175 `functions' line is now prefixed with `function:'.
6176 * bin/autoscan.in (&init_tables): Adjust.
6178 2002-09-28 Akim Demaille <akim@epita.fr>
6180 From now on, autoscan files must always map a macro name to a
6181 word: there is no `default' macro for autoscan.
6183 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6184 all.
6185 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6186 explicit.
6188 2002-09-28 Akim Demaille <akim@epita.fr>
6190 * bin/autoscan.in (%c_keywords): Remove.
6191 (&used): Keep only track of the words we might be interested in.
6192 (&output_kind): It is no longer needed to look for non active
6193 checks.
6195 2002-09-27 Akim Demaille <akim@epita.fr>
6197 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
6198 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
6199 * lib/autoscan/functions: Adjust.
6200 * doc/autoconf.texi (Particular Functions): Adjust.
6202 2002-09-27 Akim Demaille <akim@epita.fr>
6204 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
6205 from /tmp.
6206 Thanks to Bill Moseley and Paul Eggert.
6207 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6208 the tmpdir must be created.
6209 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6210 dir be in the build tree, instead of $TMPDIR.
6212 2002-09-27 Akim Demaille <akim@epita.fr>
6214 * bin/autoscan.in: Improve the comments.
6215 (&parse_args): Drop obsolete undocumented options.
6216 (&output_kind): Output warnings.
6217 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
6218 (getwd): Trigger a warning.
6220 2002-09-26 Akim Demaille <akim@epita.fr>
6222 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6223 Reported by Ralf Corsepius.
6224 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6226 2002-09-26 Akim Demaille <akim@epita.fr>
6228 Single suffix rules and seperated dependencies are not portable.
6230 * doc/autoconf.texi (Installation Directory Variables): Update.
6231 (Limitations of Make): Some about `Single Suffix Rules and
6232 Separated Dependencies'.
6233 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6234 (ifnames, autoscan, autom4te): Un-factor into several rules.
6236 2002-09-25 Paul Eggert <eggert@twinsun.com>
6238 * BUGS (Interoperability bugs): New section. Mention libtool
6239 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6241 2002-09-24 Paul Eggert <eggert@twinsun.com>
6243 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6244 make handles suffix-rules differently from GNU make.
6246 * bin/Makefile.am (SUFFIXES, .in): Remove.
6247 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6248 Move the body of the old .in rule here.
6250 2002-09-16 Akim Demaille <akim@epita.fr>
6252 i960 compilers create `b.out' files by default.
6253 Reported by Ralf Corsepius.
6255 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6256 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6258 2002-09-13 Paul Eggert <eggert@twinsun.com>
6260 * doc/autoconf.texi (Particular Headers): Remove obsolete
6261 reference to `struct timezone' in the description of
6262 AC_HEADER_TIME.
6264 2002-09-13 Akim Demaille <akim@epita.fr>
6266 Version 2.54.
6268 * config/config.sub, config/config.guess: Update.
6269 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6270 * Makefile.am: Adjust.
6272 2002-09-13 Akim Demaille <akim@epita.fr>
6274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6275 reading config.log when the compiler is rejected.
6276 Suggested by Guido Draheim.
6278 2002-09-13 Akim Demaille <akim@epita.fr>
6280 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6281 (chdir_init) might hang when stat'ing mounted directories.
6282 Reported by Vance Shipley.
6284 2002-09-12 Akim Demaille <akim@epita.fr>
6286 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6287 the lists.
6289 2002-09-12 Akim Demaille <akim@epita.fr>
6291 * doc/autoconf.texi (Defining Symbols): Present two different
6292 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6293 difference between 1 argument calls, and 2-3 argument calls.
6295 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6297 * doc/autoconf.texi: Review grammar and punctuation.
6299 2002-09-11 Paul Eggert <eggert@twinsun.com>
6301 * doc/autoconf.texi: Fix minor formatting, spelling, and
6302 grammatical typos.
6303 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6304 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6305 is obsolescent.
6307 2002-09-11 Akim Demaille <akim@epita.fr>
6309 * doc/autoconf.texi (Questions): Rename as...
6310 (FAQ): this.
6311 (Defining Directories): New.
6313 2002-09-09 Akim Demaille <akim@epita.fr>
6315 * doc/autoconf.texi (Making testsuite Scripts): Update.
6316 Suggested by Nishio Futoshi.
6318 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6320 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6321 plain `@' is wanted.
6323 2002-09-09 Akim Demaille <akim@epita.fr>
6325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6326 `duplicates', since the algorithm was too naive and could keep
6327 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6328 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6329 Reported by Ralf Corsepius.
6330 * tests/torture.at (Configuring subdirectories): Exercise these
6331 cases.
6333 2002-09-09 Akim Demaille <akim@epita.fr>
6335 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6336 looking for a replacement file.
6337 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6338 directory is relative.
6339 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6340 directory definition.
6341 Reported by Andreas Schwab and Jim Meyering.
6343 2002-09-06 Akim Demaille <akim@epita.fr>
6345 * doc/autoconf.texi (Setting Output Variables): Clarify what
6346 precious variables are.
6347 Suggested by Pontus Skoeld.
6349 2002-09-05 Akim Demaille <akim@epita.fr>
6351 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6352 (ifnames, autoscan, autom4te): Since we don't only depend on
6353 configure.ac variables (such as VERSION etc.), but also on prefix
6354 and so forth, depend on Makefile, not configure.ac.
6355 Reported by Alexandre Duret-Lutz.
6356 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6358 2002-09-05 Kevin Ryde <user42@zip.com.au>
6360 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6361 doesn't seem to be confined to ia64, just say "some versions".
6363 2002-09-04 Akim Demaille <akim@epita.fr>
6365 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6366 Automake 1.6c.
6367 * Makefile.am (maintainer-clean-local): Remove.
6368 (MAINTAINERCLEANFILES): Remove COPYING.
6370 2002-09-03 Paul Eggert <eggert@twinsun.com>
6372 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6373 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6374 Brinkmann.
6376 2002-09-03 Akim Demaille <akim@epita.fr>
6378 * configure.ac: Bump to 2.53d.
6379 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6380 as of today, on Automake's team suggestion.
6382 2002-09-03 Akim Demaille <akim@epita.fr>
6384 Version 2.53c.
6386 2002-09-02 Akim Demaille <akim@epita.fr>
6388 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6389 SITE_MACRO_DIR.
6390 * configure.ac: Disable SITE_MACRO_DIR.
6392 2002-09-02 Jim Meyering <meyering@lucent.com>
6394 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6395 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6396 Also, tweak grammar: s/make sure to/be sure to/.
6398 2002-09-02 Paul Eggert <eggert@twinsun.com>
6400 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6401 directory names are generally preferable to physical names.
6403 2002-09-02 Akim Demaille <akim@epita.fr>
6405 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6406 Reported by Raja R. Harinath.
6407 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6408 * bin/autoupdate.in: Use error instead of die.
6410 2002-09-01 Paul Eggert <eggert@twinsun.com>
6412 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6413 ordinary shell concatenation rather than echo+tr+sed command that
6414 runs afoul of a long-line-related sed bug in Solaris 8.
6416 * bin/autoheader.in (parse_args): --warning -> --warnings.
6418 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6419 stdout, as traditional "ls" does.
6420 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6421 _AC_COMPILER_EXEEXT_O): Likewise.
6422 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6424 * bin/autoconf.as: Add --prepend-include option. This patch was
6425 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6426 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6428 * bin/autoconf.in, configure: Regenerate.
6430 * doc/autoconf.texi (Special Shell Variables): Mention
6431 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6433 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6434 MAILPATH and set PS1, PS2, PS4 to default values, to work
6435 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6436 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6437 the Autoconf documentation specifies; fall back to "unset" only if
6438 this fails. Use a shell for-loop for this rather than an m4 loop,
6439 to shorten the output script.
6441 2002-08-30 Paul Eggert <eggert@twinsun.com>
6443 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6444 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6445 for the CDPATH problem. Document PWD.
6446 (Limitations of Builtins): Document the problem that "cd $foo" and
6447 "ls $foo" may refer to different directories in shells conforming
6448 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6449 example, since the old example is now out of date.
6451 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6452 FOO" and "ls FOO" talk about different directories; this catches
6453 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6454 spaghetti.
6456 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6457 of rolling our own unset.
6458 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6459 in practice we needn't worry about CDPATH if unset doesn't work.
6461 * Makefile.in, aclocal.m4, bin/Makefile.in,
6462 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6463 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6464 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6465 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6466 tests/Makefile.in: Regenerate with Automake 1.6.3.
6468 * config/config.guess, config/config.sub, config/mkinstalldirs:
6469 Update.
6471 * configure: Regenerate with self.
6473 2002-08-30 Kevin Ryde <user42@zip.com.au>
6475 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6476 default output.
6478 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6480 * bin/autom4te.in (Request::load): Correctly test for "do" read
6481 failure.
6483 2002-08-29 Akim Demaille <akim@epita.fr>
6485 * lib/Autom4te/General.pm (&xqx): New.
6486 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6487 hand, which is not portable.
6488 (&error): New.
6489 * bin/autom4te.in: Use them.
6490 Use &error instead of die.
6491 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6492 Adjust.
6494 2002-08-17 Paul Eggert <eggert@twinsun.com>
6496 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6497 default list of compilers to try, since it was long ago superseded
6498 by the ksh fc builtin. Suggested by Steven G. Johnson.
6500 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6502 * doc/autoconf.texi (Invoking autom4te): End the option table,
6503 fixing a bug introduced by the previous patch.
6504 (Limitations of Make): Add a 'target lookup' subentry in the
6505 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6507 2002-07-29 Mark D. Roth <roth@feep.net>
6509 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6510 options and use $AUTOM4TE_PATH.
6511 * doc/autoconf.texi: Remove documentation of autom4te
6512 --include-envvar and --site-macro-subdir options and document
6513 use of $AUTOM4TE_PATH.
6514 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6515 arguments from each language section.
6517 2002-07-29 Paul Eggert <eggert@twinsun.com>
6519 * doc/install.texi: Include copyright symbol in copyright notice.
6521 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6522 Replace with:
6523 (AM_MAKEINFOFLAGS): New macro.
6524 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6525 * Makefile.am (INSTALL): Use the new macros.
6526 Use -o rather than --output, since "missing" does not grok --output.
6528 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6530 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6531 comments do not always work. Never trust the exit status of
6532 `make -k'.
6534 2002-07-24 Kevin Ryde <user42@zip.com.au>
6536 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6537 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6539 2002-07-23 Paul Eggert <eggert@twinsun.com>
6541 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6542 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6543 apparently treats PATH="nonexistent" as if it contained ".".

6670 2002-06-27 Paul Eggert <eggert@twinsun.com>
6672 * config/install-sh: Quote $src. Prefer || to test's -o option,
6673 as per "Limitations of Builtins".

6737 * bin/autom4te.in (warn_forbidden): When rejecting a token,

6800 version of Autoconf that is discussed.
6802 2002-05-22 Paul Eggert <eggert@twinsun.com>
6804 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
6805 from the default list of compilers to try. Suggested by
6806 Kate Hedstrom.
6807 * NEWS: Document the above.
6808 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
6810 2002-05-17 Paul Eggert <eggert@twinsun.com>
6812 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
6813 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6814 This improves on an earlier suggestion by H. Peter Anvin.
6816 2002-05-16 Paul Eggert <eggert@twinsun.com>
6818 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6819 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6820 Both macros now accept an optional source-dir arg.
6821 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6823 * NEWS: Document this.
6824 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6826 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6827 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6828 not for GNU extensions; this undoes part of the 2000-11-03 change,
6829 reverting to 2.13-compatible behavior.
6830 Add new optional argument DIR.
6831 (AC_FUNC_FNMATCH_GNU): New macro.
6833 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6835 2002-05-08 Paul Eggert <eggert@twinsun.com>
6837 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6838 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6839 and it causes a 'test' syntax error if it fails.
6840 Bug reported by Stephen Gildea.
6842 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6843 If prototypes are supported, use them to check this at compile-time,
6844 instead of trying to check it at run-time. If we must do a run-time
6845 check, assume that setvbuf is standard when cross-compiling, as
6846 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6847 Bug reported by Paul D. Smith.
6849 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6850 argument specifying location of getloadavg.c. This removes a
6851 FIXME. This idea was taken from Jim Meyering's implementation in
6852 textutils.
6853 * doc/autoconf.texi (Particular Functions): Document this.
6854 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6855 that's what the code does; this fixes a bug reported by
6856 Paul D. Smith.
6858 2002-05-03 Akim Demaille <akim@epita.fr>
6860 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6861 autopoint instead of gettextize.
6862 ($uses_alocal): Rename as...
6863 ($uses_aclocal): this.
6864 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6865 Suggested by Bruno Haible.
6867 2002-05-03 Akim Demaille <akim@epita.fr>
6869 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
6871 2002-04-29 Paul Eggert <eggert@twinsun.com>
6873 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
6874 files to be 1 second older; just set them to be the same time.
6875 Also, sleep 1 second after the first aclocal, to work around
6876 problems with sub-second time stamps on the input files.
6878 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6880 * doc/autoconf.texi: Mention "set -e -x" lossage
6881 under node "Limitations of Builtins".
6883 2002-04-29 Akim Demaille <akim@epita.fr>
6885 * doc/install.texi: Better wording for setting variables when
6886 running configure.
6887 From Christian Cornelssen.
6889 2002-04-29 Akim Demaille <akim@epita.fr>
6891 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
6892 of lack of $LINENO support, then the test will compare the $LINENO
6893 in testsuite vs. the lineno in the test file. This is wrong, of
6894 course.
6895 Be sure to protect it.
6896 Reported by Patrick Welche.
6898 2002-04-25 Akim Demaille <akim@epita.fr>
6900 * doc/autoconf.texi (Obsolete Macros): Typo.
6901 Reported by Vladimir Volovich.
6903 2002-04-25 Akim Demaille <akim@epita.fr>
6905 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
6906 than some of the input files, hence, on the second run of aclocal,
6907 if some of its input are younger, make them older.
6908 Suggested by Paul Eggert.
6910 2002-04-25 Akim Demaille <akim@epita.fr>
6912 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
6913 Thanks to Paul Eggert.
6915 2002-04-25 Akim Demaille <akim@epita.fr>
6917 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
6918 and ac_subst_vars be sh variables containing the list of
6919 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
6920 DEFAULT diversion.
6921 (_AC_INIT_PREPARE): Use them to log them.
6922 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
6923 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
6924 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
6925 _AC_SUBST_FILES and _AC_SUBST_VARS.
6926 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
6928 2002-04-24 Akim Demaille <akim@epita.fr>
6930 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
6931 autoheader, so that automake does not complain about a missing
6932 config.h.in that was to be created.
6934 2002-04-23 Akim Demaille <akim@epita.fr>
6936 * bin/autoheader.in (parse_args): --warning takes an argument.
6937 Fixes PR/220.

6988 * doc/autoconf.texi: Follow the outline suggested in the GNU
6989 Sample Texts sections of the Texinfo 4.2 manual. Most
6990 importantly, this makes sure that the copyright notices appear in
6991 all output formats. You probably need Texinfo 4.2 to generate
6992 the manual now.

7029 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7030 workaround for ${1+"$@"}.
7031 * doc/autoconf.texi (Shell Substitutions): Explain it.
7032 From Oliver Kiddle and Peter Stephenson.
7034 Have M4sh perform minimal shell sanitizing.
7036 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7037 part into...
7038 (_AS_PREPARE): this new macro.
7039 (AS_PREPARE): New.
7040 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7041 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7043 Adjust Autoconf and Autotest.
7045 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7046 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7047 * lib/autotest/general.m4 (AT_INIT): Likewise.
7048 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7049 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7050 AS_SHELL_SANITIZE.
7052 Use this M4sh to generate Autoconf's shell scripts.
7054 * tests/wrapsh.as: New, precursor of wrapsh.in.
7055 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7056 on Autotest and M4sh.
7057 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7058 (wrapsh.in): New target.
7059 * bin/autoconf.as: New, precursor of autoconf.in.
7060 (autoconf.in): New target.
7062 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
7064 * doc/autoconf.texi (Limitations of Make): Mention the issue
7065 with indented comments in rules.
7067 2002-04-09 Andreas Schwab <schwab@suse.de>
7069 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7070 ac_top_builddir when setting ac_abs_top_builddir.

7075 (Portable Shell): Cross reference to Systemology.
7077 2002-04-05 Akim Demaille <akim@epita.fr>
7079 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7080 directories when descending in a SUBDIRS.
7081 Reported by Ezra Peisach.
7083 2002-04-04 Andreas Schwab <schwab@suse.de>
7085 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7086 contains no literal separators.
7088 2002-04-03 Akim Demaille <akim@epita.fr>
7090 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7091 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7092 Use dnl, not the KILL diversion.
7093 Extracted from...
7094 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7095 (AC_CONFIG_LINKS): here.
7096 Adjust.
7097 Don't use the KILL diversion, as it kills spurious output, which
7098 results in failures being hidden.
7099 Use m4_defn where appropriate.
7100 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7101 after the second argument.
7102 Use m4_defn.
7103 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7104 syntax, as it is provided by M4sugar.
7105 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7107 2002-04-03 Andreas Schwab <schwab@suse.de>
7109 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7110 expanded if $# <= 2.

7118 (_AC_COMPILER_EXEEXT_REJECT): New.
7119 Also recognize *.bb and *.bbg as compilation byproducts.
7120 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7121 (_AC_COMPILER_OBJEXT): Use them.
7122 Fixes Debian #138666.

7126 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7128 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7129 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7130 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7131 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7132 (AC_C_CONST): Same.
7133 (AC_C_INLINE): Same.

7142 _AS_MKDIR_P_PREPARE.
7144 2002-03-28 Kevin Ryde <user42@zip.com.au>
7146 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7147 to avoid versions of HP C which don't allow that.
7149 2002-03-27 Paul Eggert <eggert@twinsun.com>
7151 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7152 (AS_SHELL_SANITIZE): Invoke it.
7153 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

7159 2002-03-26 Akim Demaille <akim@epita.fr>
7161 * doc/autoconf.texi (Introduction): The GNATS base moved.
7163 2002-03-25 Paul Eggert <eggert@twinsun.com>
7165 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7166 as POSIX requires, as it doesn't work with Zsh.
7167 * doc/autoconf.texi (Assignments): Document the problem.
7169 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7171 * doc/autoconf.texi (Limitations of Make): Mention more issue
7172 about VPATH, overriding of macros in sub-makes, and handling of
7173 SHELL.
7175 2002-03-21 Paul Eggert <eggert@twinsun.com>
7177 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7178 problem with here-document buffer boundaries.
7180 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7181 when reinvoking the shell, to work around problems with installers
7182 who put strange things like "cd" commands in their environments.
7184 2002-03-19 Akim Demaille <akim@epita.fr>
7186 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7187 From Aaron Ucko.
7189 2002-03-19 Akim Demaille <akim@epita.fr>
7191 * bin/autoscan.in (scan_file): Specify the location in `&used'
7192 invocations.
7193 From Nicolas Joly.
7195 2002-03-19 Akim Demaille <akim@epita.fr>
7197 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7198 From Nishio Futoshi.
7200 2002-03-19 Akim Demaille <akim@epita.fr>
7202 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

7206 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7207 (Limitations of Usual Tools): Add mkdir section.
7209 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7210 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7211 back on AS_DIRNAME to compute prefixes otherwise; this is
7212 roughly what mkinstalldirs does. That way, we need not have
7213 our own filename disassembler. The old disassembler did not
7214 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7216 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7217 Create at_test_all by a series of assignments,
7218 not by a single assignment of a long string. The latter causes ksh
7219 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7220 presumably because of a buffer overrun.
7222 2002-03-14 Paul Eggert <eggert@twinsun.com>
7224 * lib/autotest/general.m4 (at_times_skip):
7225 Renamed from at_times. Now a boolean.
7226 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7227 says 'times: not found'.
7229 2002-03-14 Akim Demaille <akim@epita.fr>
7231 * bin/autoreconf.in (&study_gettextize): New.
7232 (&autoreconf): Handle newest gettextize.
7233 Rerun aclocal if needed.
7234 Suggested by Andreas Schwab.
7236 2002-03-13 Akim Demaille <akim@epita.fr>
7238 * doc/autoconf.texi (Special Shell Variables): More about IFS.
7240 2002-03-13 Akim Demaille <akim@epita.fr>
7242 * doc/autoconf.texi (Header Portability): New.
7243 Add information about stdint.h and inttypes.h from Paul Eggert.
7245 2002-03-13 Akim Demaille <akim@epita.fr>
7247 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7248 -p'.
7249 From Bob Proulx.
7251 2002-03-12 Akim Demaille <akim@epita.fr>
7253 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7254 m4_require.
7256 2002-03-11 Andreas Schwab <schwab@suse.de>
7258 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7259 does not do it if --with-lispdir is given.
7261 2002-03-08 Akim Demaille <akim@epita.fr>
7263 Version 2.53.
7265 2002-03-08 Akim Demaille <akim@epita.fr>
7267 * doc/autoconf.texi (Subdirectories): Clarify that the
7268 subdirectory should exist.
7270 2002-03-08 Akim Demaille <akim@epita.fr>
7272 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7274 2002-03-08 Akim Demaille <akim@epita.fr>
7276 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7277 aliases the actual variables, and modifications of the former
7278 affect the latter.
7280 2002-03-08 Akim Demaille <akim@epita.fr>
7282 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7283 because of C-c: have m4 output in tmp files, then mv them.
7285 2002-03-08 Akim Demaille <akim@epita.fr>
7287 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7288 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7289 * bin/ifnames.in: Copyright update.
7291 2002-03-08 Akim Demaille <akim@epita.fr>
7293 * doc/autoconf.texi (Invoking autom4te): New.
7295 2002-03-05 Akim Demaille <akim@epita.fr>
7297 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7298 Kevin Ryde.
7300 2002-03-05 Akim Demaille <akim@epita.fr>
7302 Version 2.52i.
7304 2002-03-04 Akim Demaille <akim@epita.fr>
7306 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7307 * lib/autoconf/general.m4 (AC_INIT): More informative error
7308 message for LIBOBJ.
7310 2002-03-04 Akim Demaille <akim@epita.fr>
7312 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7313 parallel builds.
7315 2002-03-04 Akim Demaille <akim@epita.fr>
7317 * doc/autoconf.texi (Transforming Names): Equality between target
7318 and host is irrelevant.
7319 (Specifying Names, Canonicalizing): Remove all references to the
7320 backward compatibility hooks. Rather, collect them all into...
7321 (Hosts and Cross-Compilation): this new section.
7322 * doc/install.texi (System Type): Ditto.
7323 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7324 that `--host' implies cross-compilation.
7326 2002-03-04 Akim Demaille <akim@epita.fr>
7328 * doc/autoconf.texi (Evaluation Macros): New.
7329 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7330 useless.
7331 (_m4_foreach): Define the variant with immediate evaluation so
7332 that it contains exactly the items, not an expression which
7333 evaluation is the current item.
7334 (m4_re_string, m4_re_word): Don't over quote them.
7336 2002-03-04 Akim Demaille <akim@epita.fr>
7338 Instead of having stacking `shift's evaluated at the end, let
7339 `foreach' loops immediately evaluate them.
7341 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7342 $*. This is the n-th time I change my mind, but hopefully this is
7343 the last...
7344 (m4_lquote): New.
7345 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7346 efficient.
7347 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7348 it was only a hack for m4_text_wrap.
7349 (m4_car2): Remove, replaced by...
7350 (m4_cdr): New.
7351 (_m4_foreach): Adjust.
7352 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7353 m4_bpatsubst for clarification.
7355 2002-03-04 Akim Demaille <akim@epita.fr>
7357 * doc/autoconf.texi (Changequote is Evil): New.
7359 2002-03-03 Kevin Ryde <user42@zip.com.au>
7361 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
7362 on old systems like SunOS.
7364 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
7366 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7367 lib/autoconf/functions.m4, lib/autoconf/general.m4,

7369 lib/autoconf/programs.m4, lib/autoconf/status.m4: Improve spelling
7370 of messages.
7372 2002-02-28 Akim Demaille <akim@epita.fr>

7375 message to be sent.
7377 2002-02-28 Kevin Ryde <user42@zip.com.au>

7381 2002-02-25 Akim Demaille <akim@epita.fr>
7383 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
7384 From Akinori Musha.
7386 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
7388 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
7389 translate \r\n to \n.
7391 2002-02-07 Akim Demaille <akim@epita.fr>
7393 Version 2.52h.
7395 2002-02-07 Akim Demaille <akim@epita.fr>
7397 Fix Autoconf PR/209.
7398 Also reported by Frank Denis.
7400 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
7402 2002-02-07 Akim Demaille <akim@epita.fr>
7404 Fix Autoconf PR/207:
7405 AC_PREFIX_PROGRAM fails with dashed program names
7407 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7408 variable when looking for the prefix program.
7409 Now it also works for shell variables.
7411 2002-02-07 Akim Demaille <akim@epita.fr>
7413 * doc/autoconf.texi (Limitations of Builtins): More about
7414 case/esac.
7416 2002-02-06 Akim Demaille <akim@epita.fr>
7418 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7419 case/esac, some shells don't support it.
7420 Reported by Zack Weinberg.
7421 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7423 2002-02-06 Akim Demaille <akim@epita.fr>
7425 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7426 sure not to introduce newlines in at_groups.
7427 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7429 2002-02-06 Akim Demaille <akim@epita.fr>
7431 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7432 is not available.
7434 2002-02-05 Paul Eggert <eggert@twinsun.com>
7436 * doc/autoconf.texi (Specific Compiler Characteristics):
7437 Describe HP-UX cc bug workaround more accurately.
7438 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7439 not unsigned long.
7440 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7441 cross-compilers, too. This undoes some of the most recent change
7442 to this file.
7444 2002-02-05 Akim Demaille <akim@epita.fr>
7446 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7447 to make sure they are up to date when `check' is run.
7449 2002-02-05 Akim Demaille <akim@epita.fr>
7451 * doc/autoconf.texi (Making testsuite Scripts): Document
7452 package.m4.
7454 2002-02-05 Akim Demaille <akim@epita.fr>
7456 * lib/freeze.mk: New.
7458 2002-02-05 Akim Demaille <akim@epita.fr>
7460 Implement `autom4te --freeze'.
7462 * bin/autom4te.in (&freeze): New.
7463 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7464 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7466 2002-02-05 Akim Demaille <akim@epita.fr>
7468 * bin/autom4te.in (&parse_args): Implement `frozen files are
7469 optional are the sum of the previous files on the command line'.
7470 Also, pass `--reload-state=' on them, so...
7471 (handle_m4): don't.
7472 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7473 (M4sh): Rely on M4sugar.
7474 (Autotest, M4sh, M4sugar): Use frozen files.
7476 2002-01-31 Akim Demaille <akim@epita.fr>
7478 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7479 * doc/autoconf.texi (Initializing configure): Adjust.
7481 2002-01-30 Akim Demaille <akim@epita.fr>
7483 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7484 alphanumeric to `-' instead of `_'.
7486 2002-01-30 Akim Demaille <akim@epita.fr>
7488 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7489 for plain code, the other for cross-compilation code. The latter
7490 is now run with GCC only.
7491 * doc/autoconf.texi (Compilers and Preprocessors): New.
7493 2002-01-30 Akim Demaille <akim@epita.fr>
7495 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7496 values.
7497 * doc/autoconf.texi (Initializing configure): Explain how to
7498 change AC_INIT default values.
7500 2002-01-29 Akim Demaille <akim@epita.fr>
7502 * tests/torture.at (Configuring subdirectories): Use configure.in,
7503 so that aclocal 1.4 works.
7504 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7506 2002-01-28 Akim Demaille <akim@epita.fr>
7508 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7509 needs an argument.
7511 2002-01-28 Akim Demaille <akim@epita.fr>
7513 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7514 AUTOTEST_PATH *after* it was set.
7515 Don't put `.' in the PATH: the user should be precise and `./' if
7516 needed. In addition, given that the test suite does some `cd', if
7517 `.' is in the path, the `tested programs' sections will report
7518 programs found in the test suite's directory, while during the
7519 tests (performed in their own directory), these programs are no
7520 longer visible. In other words, the results is confusing and
7521 useless.
7522 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7524 2002-01-24 Akim Demaille <akim@epita.fr>
7526 Version 2.52g.
7528 2002-01-24 Akim Demaille <akim@epita.fr>

7531 * doc/autoconf.texi: Finally add Akim as an author.
7533 2002-01-24 Akim Demaille <akim@epita.fr>
7535 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7536 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be

7547 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
7548 * config/auxdir.m4, config/cond.m4, config/depend.m4,
7549 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
7550 * config/missing.m4, config/sanity.m4, config/select.m4,
7551 * config/strip.m4: Remove, to ease sync'ing with any version of
7552 Automake.
7554 2002-01-24 Akim Demaille <akim@epita.fr>
7556 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7557 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7558 Reported by Geir Ove Myhr.
7560 2002-01-21 Akim Demaille <akim@epita.fr>

7564 2002-01-21 Akim Demaille <akim@epita.fr>
7566 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7567 message on invalid options.

7587 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7588 package.m4, since is really depends upon configure.ac, not
7589 configure.
7590 * doc/autoconf.texi (testsuite Scripts): Adjust.
7591 * tests/Makefile.am (package.m4): New.
7592 EXTRA_DIST it since its a source.
7594 2002-01-06 Akim Demaille <akim@epita.fr>
7596 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7597 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7598 and PACKAGE_BUGREPORT from here...
7599 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7600 arguments.
7601 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7602 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

7611 2002-01-03 Akim Demaille <akim@epita.fr>
7613 * doc/autoconf.texi (Output): Improved wording regarding use of
7614 AC_OUTPUT.

7619 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7620 sometimes needing writable input.
7622 2001-12-17 Jim Meyering <meyering@lucent.com>
7624 * doc/autoconf.texi (New Macros): Tweak wording.
7626 2001-12-14 Akim Demaille <akim@epita.fr>
7628 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7629 trailing files, don't apply `-rf' to files which might not be
7630 created by configure (core, core.*, and *.core), but just `rm -f'.
7631 Suggested by Jonathan Kamens.
7633 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7635 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7637 2001-12-14 Akim Demaille <akim@epita.fr>
7639 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7641 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

7644 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7645 abs_srcdir, top_srcpath to abs_top_srcdir.
7646 (_AC_OUTPUT_FILES): Adjust.
7647 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7648 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7649 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7651 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
7653 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
7654 C/Fortran linking on HP/UX, by extracting the Fortran library
7655 search path from the LPATH line in the $F77 -v output.
7657 2001-12-12 Kevin Ryde <user42@zip.com.au>
7659 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7660 forbidden file descriptors table.
7662 2001-11-26 Akim Demaille <akim@epita.fr>
7664 * bin/autoscan.in (%c_keywords): Build it at top level.
7665 Map to 1 in order to simplify its uses.
7667 2001-11-26 Akim Demaille <akim@epita.fr>
7669 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7670 Remove $filepath, useless.
7671 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7672 variables, they are really part of the tokens.
7673 Split the input line on spaces and then look for tokens.
7674 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7675 because of `lex$U.$(OBJEXT)'.
7676 (&scan_files): Use "@list" instead of join.
7677 * doc/Makefile.am (CLEANFILES): Add *.fns.
7679 2001-11-26 Akim Demaille <akim@epita.fr>

7686 * lib/autoscan/headers: errno.h is portable.
7688 2001-11-26 Akim Demaille <akim@epita.fr>
7690 * bin/autoscan.in (used): New.
7691 Use it.
7693 2001-11-26 Akim Demaille <akim@epita.fr>
7695 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7696 directives.
7697 (&scan_sh_file): Remove a duplicate pattern.
7698 (&check_configure_ac): Use long options.
7699 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

7703 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
7704 Before, having a line containing the opening of a multi line
7705 comment made the whole line be ignored.
7707 2001-11-26 Akim Demaille <akim@epita.fr>
7709 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7710 (testsuite Scripts): Be one of its subsection.
7711 (Autotest Logs): New.
7713 2001-11-26 Akim Demaille <akim@epita.fr>
7715 Test groups are now run two directories deeper.
7717 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7718 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7719 at_top_builddir.
7720 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7721 top_srcdir, builddir and top_builddir.
7722 Use `at_*dir' relatively to the directory containing the
7723 suite, use `*dir' when relatively to the current group dir.
7725 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7727 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7728 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7729 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7730 spelling errors.
7732 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7734 * doc/autoconf.texi (Using System Type): Add an example of `case
7735 $host' usage so people quit using `case $target' everywhere.
7737 2001-11-22 Akim Demaille <akim@epita.fr>
7739 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7740 spotted by Jim Meyering.
7742 2001-11-16 Paul Eggert <eggert@twinsun.com>
7744 This patch implements a `long double' suggestion by Oliver Kiddle.
7746 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7747 static, to catch errors if the value isn't known at compile-time
7748 and the compiler supports dynamic arrays. Change its name from
7749 `_array_' to `test_array' to avoid potential name clashes.
7750 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7751 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7752 better than double. Catch a bug in GCC 2.95.2 x86.
7753 * doc/autoconf.texi (C Compiler): Document the above.
7754 * NEWS: Likewise.
7756 2001-11-13 Akim Demaille <akim@epita.fr>
7758 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7759 hand.
7760 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7762 2001-11-13 Akim Demaille <akim@epita.fr>
7764 * lib/autotest/general.m4 (AT_INIT): After having run the test
7765 group, go back to the initial directory, not to at_suite_dir.
7767 2001-11-13 Akim Demaille <akim@epita.fr>
7769 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7770 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7771 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7772 option.
7773 (AT_CHECK_CONFIGURE): Use absolute paths.
7774 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7775 The problem is still the old one: there is no means in M4 (that I
7776 know about) to create a defining macro, because there is no means
7777 to create `$1' etc., therefore, the defining macro ``swallows''
7778 all the arguments meant to the defined macro.
7780 2001-11-13 Akim Demaille <akim@epita.fr>
7782 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7783 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7784 configure.ac.
7785 * tests/aclocal.m4: Remove, as it is no longer used.
7787 2001-11-13 Akim Demaille <akim@epita.fr>
7789 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7790 variable names when referring to a single test group, or to
7791 `suite' when referring to the whole test suite.
7792 `at_last_test' is removed: m4 compute at_format itself.
7793 (at_stdout, at_stder1, at_stderr): New variables.
7794 (AT_CHECK): Use them.
7796 2001-11-13 Akim Demaille <akim@epita.fr>
7798 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7799 in PATH.
7800 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7801 Do it as soon as a test fails, don't wait till the end of the test
7802 suite.
7803 Don't remove $as_me.[0-9]*, since these files no longer exist.
7805 2001-11-13 Akim Demaille <akim@epita.fr>
7807 * tests/tools.at: Use absolute paths, since we are no longer run
7808 in place.
7810 2001-11-13 Akim Demaille <akim@epita.fr>
7812 Now that tests are running in their own private dir, there is no
7813 need to list the files to remove at the end of tests groups.
7815 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7816 (AT_data_files, at_data_files): Remove.
7817 (AT_CLEANUP, AT_DATA): Simplify.
7818 (AT_INIT): Adjust.
7819 Remove the group dir if !debug && !failed.
7820 * tests/atspecific.m4: Adjust.
7822 2001-11-13 Akim Demaille <akim@epita.fr>
7824 Start a new layout for Autotest: `testsuite' creates
7825 `testsuite.dir' in which the at-check-line etc. files are to be
7826 found, and `testsuite.dir/003' where the test group 3 is run.
7828 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7829 at_check_line_file, at_format, at_test_normalized, at_group_dir
7830 are new variables.
7831 Create the directories.
7832 Use absolute paths for at- files.
7833 (AT_CHECK): Adjust.
7835 2001-11-11 Michael Matz <matz@kde.org>
7837 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7838 (m4_car2): New.
7839 (m4_car): Properly quote arguments.
7841 2001-11-13 Akim Demaille <akim@epita.fr>
7843 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7844 with stricter rules on LIBOBJS.
7846 2001-11-12 Paul Eggert <eggert@twinsun.com>
7848 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7849 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7850 __PROTOTYPES too.
7852 2001-11-12 Akim Demaille <akim@epita.fr>
7854 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7856 2001-11-12 Akim Demaille <akim@epita.fr>
7858 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7859 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7860 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7861 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7862 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7863 specify to what the macro should be defined (typically to 1).
7865 2001-11-12 Akim Demaille <akim@epita.fr>
7867 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7868 From Jim Meyering.
7870 2001-11-12 Akim Demaille <akim@epita.fr>
7872 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
7873 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
7874 definition used by Automake where LEX is +/- "${missing} lex" and
7875 `missing' itself contains variables.
7877 2001-11-12 Akim Demaille <akim@epita.fr>
7879 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7880 Now that M4sh pushes BODY, the comments were output at the end of
7881 the test suites.
7883 2001-11-08 Akim Demaille <akim@epita.fr>
7885 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7886 that we can trace macros from aclocal.m4.
7887 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7888 obsoleted, and redirect to the former anyway.
7889 Reported by Ralf Corsepius.
7891 2001-11-08 Akim Demaille <akim@epita.fr>
7893 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
7894 processed only if present.
7895 * tests/torture.at (Configuring subdirectories): Use autoreconf
7896 instead of successive calls to autoconf.
7897 Add a nonexistent subdirectory to exercise the patch above.
7898 Reported by Ralf Corsepius.
7900 2001-11-08 Kevin Ryde <user42@zip.com.au>
7902 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
7903 doesn't accept .S files.
7905 2001-11-07 Akim Demaille <akim@epita.fr>
7907 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
7908 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
7909 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
7910 * bin/autom4te.in (warn_forbidden): New.
7911 (handle_output): Use it.
7912 Read m4_pattern_forbid with messages.
7914 2001-11-05 Akim Demaille <akim@epita.fr>
7916 * bin/autom4te.in (--normalize): Remove.
7917 * lib/autom4te.in: Adjust.
7919 2001-11-05 Akim Demaille <akim@epita.fr>
7921 * tests/Makefile.am (testsuite): Rename this target as...
7922 ($(TESTSUITE)): this.
7923 From Nicolas Joly.
7925 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
7927 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
7928 the --prefix option, also remove it's argument.
7930 2001-11-05 Akim Demaille <akim@epita.fr>
7932 * doc/autoconf.texi (testsuite Invocation): Update.
7933 (Writing testsuite.at): Update.
7935 2001-11-03 Akim Demaille <akim@epita.fr>
7937 * doc/autoconf.texi: s/@code/@command/ where appropriate.
7939 2001-11-03 Akim Demaille <akim@epita.fr>
7941 * lib/Autom4te/General.pm: (&catfile, &canonfile)
7942 (&file_name_is_absolute): New, wrappers around routines from
7943 File::Spec.
7944 Use and export them.
7945 (&find_configure_ac): Optionally take a directory where to look at.
7946 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
7947 the arguments.
7948 Default @ARGV to `.', not find_configure_ac.
7949 (&autoreconf): Argument is a directory.
7950 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
7951 * doc/autoconf.texi (autoreconf Invocation): Update.
7953 2001-11-03 Akim Demaille <akim@epita.fr>
7955 * lib/Autom4te/General.pm (@export_vars, @export_subs)
7956 (@export_forward_subs): New.
7957 Add basename, dirname, and fileparse.
7958 (@EXPORT): Adjust.
7959 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
7960 Don't look for aclocal flags if we already know aclocal is not
7961 used.
7962 Move aclocal.m4t only if it exists.
7963 Reported by Ezra Peisach.
7965 2001-11-03 Akim Demaille <akim@epita.fr>
7967 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
7968 passed on command line, defaulting to ./configure.ac if present.
7969 (&maybe_autoreconf, File::Find): Remove, unused.
7970 (&autoreconf): If autoconf is not used, don't try to trace.
7972 2001-11-02 Akim Demaille <akim@epita.fr>
7974 * configure.ac: Bump to 2.52g.
7976 2001-11-02 Akim Demaille <akim@epita.fr>
7978 Version 2.52f.
7980 2001-11-02 Akim Demaille <akim@epita.fr>
7982 * config/config.guess, config/config.sub, doc/standards.texi:
7983 * config/lispdir.m4: Update from masters.
7984 * configure.ac: Bump to 2.52f.
7986 2001-11-02 Akim Demaille <akim@epita.fr>
7988 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
7989 Don't run aclocal when aclocal.m4 is not from aclocal.
7990 From Ezra Peisach.
7991 Don't run libtoolize and gettextize if --install is not given.
7993 2001-11-01 Paul Eggert <eggert@twinsun.com>
7995 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
7996 be invoked before _AS_LINENO_PREPARE.
7997 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
7998 than character ranges.
8000 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8001 invoking AS_BASENAME. Set the locale variables to 'C' if
8002 possible, as POSIX requires this to get the traditional
8003 behavior.
8004 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8006 2001-10-31 Paul Eggert <eggert@twinsun.com>
8008 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8009 with {}, as that triggers a bug in Bash 2.05.
8011 (_AS_LINENO_PREPARE): Use Sed rather than
8012 Awk. Fix the sed prepass to work even if there are multiple
8013 instances of $LINENO on the same line. Do not substitute for
8014 other variables like $LINENOT. Do not check file dates; such a
8015 check is unreliable on sufficiently fast machines, and removing
8016 the check makes the code simpler and more reliable. Check for
8017 output and chmod failures.
8019 * doc/autoconf.texi (Special Shell Variables): Document
8020 the above.
8022 2001-10-31 Akim Demaille <akim@epita.fr>

8029 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not

8034 2001-10-26 Paul Eggert <eggert@twinsun.com>
8036 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8037 lib/Autom4te/Struct.pm:
8038 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8039 with 5.005_02.
8041 * doc/autoconf.texi (Special Shell Variables): Document some
8042 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8044 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.

8065 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8066 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8067 POSIX decided to standardize on the int flavor of strerror_r.
8068 Always do char* test, as there's no reason not to.
8069 Assign to a char* var, to catch strerror_r that returns int*.
8071 * doc/autoconf.texi (Particular Functions):
8072 Document the above changes. Also, document the fact that
8073 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

8098 Remove, dead.
8099 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8100 `intl' is already present, as it refuses unless --force.
8101 (&parse_args): Use -I, --include instead of the old Autoconf
8102 options.
8103 ($localdir, $autoconf_dir): Remove.
8104 (@include): New.

8128 configure.ac being studied.
8130 2001-10-18 Paul Eggert <eggert@twinsun.com>
8132 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

8143 contains white space.
8144 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

8146 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8147 Allow "dirname //FOO" to return either / or //, as POSIX allows
8148 either behavior.

8294 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

8379 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

8412 (AC_PROG_CPP requires AC_PROG_CC): here and...
8413 * tests/fortran.at (GNU Fortran 77): there.
8414 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8415 AC_TRY_RUN is about compilation, not shell commands.

8429 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

8498 * lib/Autom4te/General.pm (&debug): New.
8499 * bin/autom4te.in ($language): Move to...
8500 (parse_args): here.
8501 Handle --language in languages.
8502 * lib/autom4te.in (Automake-selections, Autoheader-selections)
8503 (Autoscan-selections): New.
8504 (Autoconf): Adjust.

8517 2001-09-22 Akim Demaille <akim@epita.fr>
8519 * lib/autoconf/autotest.m4: Create `package.m4'.
8520 * tests/Makefile.am (package.m4): Remove.
8522 2001-09-22 Akim Demaille <akim@epita.fr>
8524 Rely on `$LINENO' when possible instead of `__oline__'.
8526 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
8527 `$LINENO' support replacement when not supported.
8528 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
8529 them explicitly to be sure they are not output before this section
8530 (via m4_require). Cosmetic only.
8531 * lib/autoconf/c.m4, lib/autoconf/general.m4,
8532 * lib/autoconf/programs.m4: Replace all the occurrences of
8533 `__oline__' with `$LINENO'.
8534 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
8536 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
8538 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
8539 character (u: -> ue) in a code comment.
8540 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
8541 it works.
8543 2001-09-21 Akim Demaille <akim@epita.fr>
8545 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
8546 Suggested by Jim Meyering.
8548 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8550 * lib/autoconf/programs.m4: Use extensions listed in

8557 setting up ac_dir_suffix and ac_top_builddir.
8558 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
8560 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8562 * doc/autoconf.texi (File System Conventions): Clarify the use of
8563 PATH_SEPARATOR.
8564 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
8565 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8566 be used instead of ':'.
8567 * lib/autotest/general.m4: Replace occurrences of ':' in
8568 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
8570 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8572 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
8573 arguments. Fixed a typo.
8575 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8577 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8578 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8580 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8582 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

8589 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8591 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8592 already have $file). Set output files to binary mode (helps avoid
8593 CR issues on DOSish systems).
8595 2001-09-19 Akim Demaille <akim@epita.fr>
8597 * lib/autotest/general.m4: Englishoes.
8598 From Tim Van Holder and Alexey Mahotkin.
8600 2001-09-18 Paul Eggert <eggert@twinsun.com>
8602 * doc/autoconf.texi (Common Shell Constructs): New node,
8603 documenting AS_DIRNAME.
8604 (Limitations of Usual Tools): Refer to it when discussing dirname.
8605 Also, update discussion of POSIX standard to reflect latest draft.
8607 * lib/autoconf/c.m4:
8608 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8610 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8611 Do not pass a first argument with leading '-'
8612 to expr, by parenthesizing initial integers that might be negative.
8614 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8615 now merely checks whether it is an error to pass an argument
8616 to getpgrp.
8618 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8619 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8620 whether it is a (compile-time) error to pass an argument to
8621 getpgrp. This simpler test supports the revised documentation,
8622 and is all that AC_FUNC_GETPGRP's users really need.
8624 2001-09-18 Akim Demaille <akim@epita.fr>
8626 * doc/autoconf.texi (Limitations of Make) <$<>: New.
8628 2001-09-18 Akim Demaille <akim@epita.fr>

8634 2001-09-18 Paul Wagland <paul@wagland.net>
8636 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8637 correctly.
8638 Add test for AS_BASENAME.
8639 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8640 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8641 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8642 * tests/base.at: Fixed the expected responses. The old ones were
8643 one line out...
8644 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8645 the documentation claims it should (and how it behaved in 2.13).
8647 2001-09-18 Akim Demaille <akim@epita.fr>
8649 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8650 the AC_CONFIG_COMMANDS invocation.
8651 This also solves the name clash problems.
8652 Don't set the package's ID.
8653 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8654 No longer to be shipped.
8655 (version.in): Remove.
8656 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8657 * lib/autoconf/status.m4: Adjust.
8658 Use `m4_PACKAGE_STRING'.
8659 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8660 the only optional argument is the name of the test suite.
8661 Expect `package.m4' to define the package signature.
8662 * lib/autom4te.in (Autotest): Add `package.m4?'.
8663 * tests/Makefile.am (package.m4): New.
8664 * tests/suite.at: ifnames is a victim.
8666 2001-09-18 Akim Demaille <akim@epita.fr>
8668 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8669 AC_LIBSOURCE, AC_CONFIG_FILES.
8670 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8671 program version string doesn't match the package's.
8672 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8673 after `(cached)'.
8675 2001-09-17 Paul Eggert <eggert@twinsun.com>
8677 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8678 Allow expression to return any value that can fit into unsigned long
8679 (not int, as before). Check for output errors.
8681 2001-09-17 Bruno Haible <haible@ilog.fr>
8683 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8684 Always include <stdio.h> and <stdlib.h>. Evaluate
8685 the expression in an extra function before these includes. Call
8686 fprintf "%d" only after ensuring the argument is of type 'int'.
8687 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8689 2001-09-17 Paul Eggert <eggert@twinsun.com>
8691 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8692 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8693 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8694 when they don't exist.
8696 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8697 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8698 need it.
8700 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8701 version with the version used by fileutils 4.1, except use
8702 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8703 we don't need it.
8705 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8707 2001-09-13 Akim Demaille <akim@epita.fr>
8709 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8710 _first_.
8711 Reported by Gerrit P. Haase.
8713 2001-09-13 Akim Demaille <akim@epita.fr>
8715 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8731 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
8732 Likewise.
8733 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
8734 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
8735 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
8736 AT_tests_all for consistency.
8737 Set at_victims.
8738 (AT_VICTIMS): Similar to AT_KEYWORDS.
8739 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
8741 2001-09-13 Akim Demaille <akim@epita.fr>
8743 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8745 2001-09-13 Akim Demaille <akim@epita.fr>
8747 * lib/autotest/general.m4 (AT_INIT): Create and remove
8748 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8749 test suites can cohabit.
8751 2001-09-13 Akim Demaille <akim@epita.fr>
8753 * tests/mktests.sh: Don't output banners for empty test files.
8755 2001-09-13 Akim Demaille <akim@epita.fr>
8757 Test suites can be run independently of configure.

8801 Spread a few keywords in the Autoconf test suite.
8803 2001-09-10 Akim Demaille <akim@epita.fr>
8805 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
8806 PATH_SEPARATOR, let M4sh compute it.
8807 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
8808 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

8821 2001-09-07 Akim Demaille <akim@epita.fr>

8824 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
8825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
8826 related variables into `at_package_*'.

8852 to avoid GCC warnings.
8853 From Uwe Seimet.

8859 2001-09-05 Akim Demaille <akim@epita.fr>
8861 Be ready to handle filenames as stupid as `dnl.at', for if even
8862 the maintainer is dumb enough to do that...
8864 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8865 excellence in M4 quotation: consider `__file__' is active.
8867 And BTW, when invoking m4, pass the --include in the right order:
8868 the wrong one.
8870 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
8871 4m.

8893 2001-09-05 Akim Demaille <akim@epita.fr>

8898 New, extracted from main.
8899 Use IO::File wherever possible.
8900 (input.m4): Be constant, use -I instead of hard coding $tmp.
8901 Therefore be a quoted heredoc.
8902 Don't invoke `_au_disable', since ac was not loaded, but just
8903 `unm4.m4'.
8905 2001-08-31 Akim Demaille <akim@epita.fr>
8907 Version 2.52d.

8930 2001-08-31 Akim Demaille <akim@epita.fr>
8932 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
8933 (testsuite Scripts): There is no such thing as `atconfig.in'.
8934 And actually one diagram is missing: test suite runtime.
8936 2001-08-31 Akim Demaille <akim@epita.fr>
8938 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
8939 inverse order.
8941 2001-08-31 Akim Demaille <akim@epita.fr>
8943 * bin/autoupdate.in (@include): `installcheck' revealed the path
8944 to m4sugar was lacking!
8946 2001-08-31 Akim Demaille <akim@epita.fr>
8948 * man/Makefile.am (.x.1): We really have to pass
8949 autom4te_perllibdir.
8951 2001-08-31 Akim Demaille <akim@epita.fr>
8953 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
8954 debug scripts, in particular passing explicitly listed tests to
8955 run is stupid.
8957 2001-08-31 Akim Demaille <akim@epita.fr>
8959 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
8960 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
8961 Use directly autom4te, not autoconf.
8962 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
8964 2001-08-31 Akim Demaille <akim@epita.fr>
8966 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

8971 * doc/autoconf.texi: Catch up -I, --include changes.
8973 2001-08-31 Akim Demaille <akim@epita.fr>
8975 * bin/autom4te.in (&parse_args): Die on unknown languages.
8976 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
8977 need for autoconf.
8978 Promote --include over --macrodir and other obsolete options.
8980 2001-08-31 Akim Demaille <akim@epita.fr>
8982 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
8983 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
8984 * bin/autom4te.in ($autoconf): Pass --force.
8985 `print $out' doesn't print `$_' but `$out'.
8986 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
8987 (autoheader): Pass --force since the test suite goes too fast for
8988 the time stamps.
8989 Adjust to the new autoheader messages.
8991 2001-08-31 Akim Demaille <akim@epita.fr>
8993 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
8994 Check the completeness of the #template.
8995 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
8996 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
8997 invocation.
8999 2001-08-31 Akim Demaille <akim@epita.fr>
9001 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9002 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9003 Drop AC_MACRODIR dead for real.
9004 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9005 `autoheader: `config.hin' is created'.
9006 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9008 2001-08-31 Akim Demaille <akim@epita.fr>
9010 * bin/autoheader.in: Rewrite in Perl.
9011 * tests/autoheader: Adjust.
9013 2001-08-31 Akim Demaille <akim@epita.fr>
9015 * bin/autoconf.in (--include, -I): New option.
9016 Map --localdir, --autoconf-dir onto it.
9017 Forward autom4te's options instead of interpreting them.
9018 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9019 There is no such envvar since the inception of autom4te.cfg.
9020 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9021 * bin/autoupdate.in: Adjust, and perform more control.
9022 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9023 * tests/autoconf: Dittowise.
9025 2001-08-31 Akim Demaille <akim@epita.fr>
9027 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9028 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9029 optionally `FILE'.
9030 Use -e, not -f, since /dev/null for instance is OK.
9031 (&parse_args): Adjust.
9032 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9034 2001-08-31 Akim Demaille <akim@epita.fr>
9036 * configure.ac: Also find tested executables in bin.
9037 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9038 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9039 installed peer executables, only PATH is allowed to resolve it.
9040 Pass `autoconf_dir' via options, not via invisible envvars.
9041 * lib/Autom4te/General.pm (&find_peer): Remove.
9042 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9043 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9044 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9045 find the executables for it.
9046 * tests/Makefile.am: Major cleanup. Too lazy to document...
9047 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9048 We only need PERL.
9049 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9050 indeed related to running the test suite, while passing
9051 --autoconf-dir and others is related to running non installed
9052 Autoconf executables. So don't do that, leave it to...
9053 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9054 * tests/autoscan: New.
9055 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9056 refer to library files: rely on --language.
9058 2001-08-29 Akim Demaille <akim@epita.fr>
9060 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9061 s/--set/--language/.
9063 2001-08-29 Akim Demaille <akim@epita.fr>
9065 * doc/autoconf.texi: Strip the @nodes.

9069 2001-08-29 Akim Demaille <akim@epita.fr>
9071 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9072 Suggested by Paul Eggert.
9074 2001-08-29 Akim Demaille <akim@epita.fr>
9076 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9077 download in a tmp dir.
9079 2001-08-29 Akim Demaille <akim@epita.fr>
9081 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9082 case insensitive OSes out there :(
9083 From Tim Van Holder.

9100 * lib/autotest/general.m4: Use
9101 foo=`(command) 2>/dev/null`
9102 not
9103 foo=`command` 2>/dev/null
9104 (at-devnull): Rename as...
9105 (AT-devnull): this.
9106 (--clean): Remove AT-* files too.
9107 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
9108 Reported by Nicolas Joly.

9142 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9143 Support `VAR=VAL' as arguments.
9144 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
9145 may be set via the command line.
9147 2001-08-27 Akim Demaille <akim@epita.fr>
9149 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

9174 (Initializing configure): this new node.
9176 2001-08-27 Akim Demaille <akim@epita.fr>

9232 (AMTAR): Help automake define it.
9233 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer

9251 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9252 the name of the directory they're in, instead of the filename,
9253 since version.m4 is now in m4sugar, but m4_acversion must not be
9254 classified as an Autoconf macro.
9255 ($input_m4): Don't qualify the path to m4sugar.
9256 Rather, pass autoconf_dir to m4.
9257 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

9272 of config.log on traps.
9273 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.

9329 * configure.ac (AT_CONFIG): Fix the path.
9330 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52

9337 AC_COMPILE_IFELSE. Cleanup grep usage.
9339 2001-08-20 Akim Demaille <akim@epita.fr>
9341 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9342 * NEWS, README, README-alpha, TODO, tests/README: This package is
9343 `Autoconf', not `autoconf' (the executable).
9345 2001-08-20 Akim Demaille <akim@epita.fr>
9347 Info readers seem to need `Index' in the index node title :(
9349 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9350 simplified index node names.
9352 2001-08-20 Akim Demaille <akim@epita.fr>
9354 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
9355 arguments are not literals.

9359 2001-08-20 Akim Demaille <akim@epita.fr>
9361 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
9362 (Examining Syntax) <AC_TRY_COMPILE>
9363 (Examining Libraries) <AC_TRY_LINK>
9364 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
9365 their arguments.
9366 Reported by Werner Lemberg.
9368 2001-08-20 Akim Demaille <akim@epita.fr>
9370 * lib/autotest/general.m4 (AT_INIT): Compute top_builddir,

9389 Configure atlocal.in if present.
9390 * tests/atconfig.in: Remove.

9394 2001-08-20 Akim Demaille <akim@epita.fr>
9396 Huh!?!?! There are still some user EOF tags used, which prevents
9397 their use in AC_CONFIG_COMMANDS for instance...
9399 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
9400 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
9401 `_CSEOF', or `_ATEOF', as appropriate.
9402 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
9403 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

9413 Autotest invokes M4sh's initialization.
9415 * lib/autotest/general.m4: Adjust the diversion names.

9463 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9464 `$0.log' as for projects where testsuite is in src, we'd have
9465 testsuite.log created in src.
9467 2001-08-17 Akim Demaille <akim@epita.fr>
9469 * bin/autom4te.in (&parse_args): Recognize --normalize.

9479 2001-08-17 Akim Demaille <akim@epita.fr>
9481 * doc/autoconf.texi: Work around Texinfo buglets.
9482 (Transformation Rules): One example is enough, users are expected
9483 to have their brains on. And BTW, use DESTDIR.
9484 (dvar): New macro. Use it.
9486 2001-08-17 Akim Demaille <akim@epita.fr>
9488 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

9525 2001-08-15 Akim Demaille <akim@epita.fr>
9527 * doc/autoconf.texi (Function Portability): sprintf's return
9528 value.
9529 From Kevin Ryde.
9531 2001-08-15 Akim Demaille <akim@epita.fr>

9536 (cvs-dist): depends upon it.
9538 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9540 * tests/Makefile.am: Use a clean-local rule to remove
9541 autom4te.cache (it's a directory, not a file.
9542 * Makefile.am: Ditto (but maintainer-clean-local).
9544 2001-08-15 Akim Demaille <akim@epita.fr>
9546 * bin/autom4te.in (@m4_warning): New.
9547 (&handle_m4): Use it.
9548 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9549 warnings are issued at each run.
9550 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9551 is in the src tree.
9553 2001-08-15 Akim Demaille <akim@epita.fr>
9555 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9556 don't waste time running `autoupdate --version' works.
9557 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9559 2001-08-13 Akim Demaille <akim@epita.fr>

9614 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9616 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9618 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9620 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9621 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9622 * doc/autoconf.texi (C Compiler Characteristics): Update
9623 documentation for AC_C_BIGENDIAN.
9625 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9627 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9628 magic values from an object file when cross-compiling.
9629 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9631 2001-08-10 Akim Demaille <akim@epita.fr>
9633 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9634 effects.
9635 Suggested by Russ Allbery.
9637 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9639 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9640 current $prefix to the sub-configures.
9642 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9644 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9645 extension (needed on BeOS). Reported by Guido van Rossum.
9647 2001-08-09 Akim Demaille <akim@epita.fr>
9649 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9651 2001-08-07 Akim Demaille <akim@epita.fr>
9653 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9654 removed.
9655 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9656 No need to remove the files before and after the each test, before
9657 each test and at the end of the suite is enough.
9658 Display only the children `times', not the shell's.
9659 If the test failed or was skipped, at-times is not available.
9661 2001-08-07 Akim Demaille <akim@epita.fr>
9663 Always produce testsuite.log, including when there are no
9664 failures. This helps getting information on skipped tests, and
9665 duration of the tests. Err, implement the latter btw.
9667 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9668 Dump information on the first run of each test.
9669 (AT_CLEANUP): Create `at-times' containing the duration of the
9670 test group.
9672 2001-08-07 Akim Demaille <akim@epita.fr>
9674 The use of `dumpstat' revealed that `len' was used although it
9675 should not. m4_text_wrap was using it, but in the Autoconf world
9676 where it is legal. Hence (i) test M4sh in its own world, not
9677 Autoconf's, and (ii), ahem, fix the bug :)
9679 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9680 does not like `' instead of [].
9681 (AT_INIT): Forbid `^_?AT_'.
9682 And don't output such tokens.
9683 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9684 `script.as', and `autom4te.cache'.
9685 Remove `empty' and `macro' which are no longer used.
9686 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9687 * tests/m4sugar.at: Use it.
9688 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9690 2001-08-07 Akim Demaille <akim@epita.fr>
9692 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9694 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9696 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9698 2001-08-04 Akim Demaille <akim@epita.fr>
9700 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9701 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9702 AC_TRY_LINK.
9703 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9704 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9705 (AC_F77_MAIN): Likewise.
9707 2001-08-04 Akim Demaille <akim@epita.fr>
9709 Don't rely on M4sugar outputting the patterns in files, since we
9710 might process the output _without_ running m4, hence without these
9711 files.
9713 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9714 * bin/autom4te.in (@Request::includes): Remove, unused.
9715 (@Request::source): Rename as...
9716 (@Request::input): this.
9717 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9718 (&handle_output): Fetch the patterns from the traces.
9719 `$forbidden' and `$allowed' are constant: use m//o.
9720 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9721 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9723 2001-08-04 Akim Demaille <akim@epita.fr>
9725 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9726 autoconf', i.e., in addition to caching traces, cache the output.
9728 * bin/autom4te.in (Request::cache): Rename as...
9729 (Request::id): this.
9730 ($cache, $icache, $tcache, $ocache): New.
9731 (&handle_m4): Save M4 output in the cache instead of $tmp.
9732 (&handle_output): Adjust.
9733 (&up_to_date_p): Check that the output cache is up to date too.
9734 (top level): Run `&handle_m4' iff force or the cache is invalid.
9735 Run `&handle_output' if the output cache is more recent.
9737 2001-08-04 Akim Demaille <akim@epita.fr>
9739 * bin/autom4te.in ($force): New.
9740 (&parse_args, &print_usage): -f, --force is a new option.
9741 (&handle_output): CPP directives might have spaces after `#'.
9742 (&parse_args): The first file only can be frozen.
9744 2001-08-04 Akim Demaille <akim@epita.fr>
9746 Don't let autom4te compute the `include' traces several times:
9747 first check that the trace cache file is up to date, and then
9748 compare its timestamp with that of the output.
9750 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
9751 the preamble. Don't require 5.005 as Autom4te::General does it,
9752 and better yet (use `use', not `require'!).
9753 * lib/Autom4te/Struct.pm: Rename the last occurrences of
9754 Class::Struct as Autom4te::Struct.
9755 * lib/Autom4te/General.pm (File::stat): Use it.
9756 (&mtime): New, export it.
9757 * bin/autom4te.in: Use it.
9758 Declare `$req' is invalid if it is outdated.
9759 Don't declare it valid before saving it if something went wrong.
9761 2001-08-04 Akim Demaille <akim@epita.fr>
9763 Autom4te shall not encode Autoconf data, and preselecting traces
9764 must be proposed to the users.
9766 * bin/autom4te.in (@required_trace): Remove.
9767 (@preselect): New.
9768 (&parse_args, &print_usage): -p, --preselect is a new option.
9769 (&up_to_date_p): Adjust.
9770 * bin/autoconf.in: Preselect some Autoconf macros.
9772 2001-08-04 Akim Demaille <akim@epita.fr>
9774 * tests/tools.at (autoconf --trace: user macros): Check traces on
9775 macros invoked without arguments, and macros invoked with multiple
9776 lines arguments.
9778 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
9780 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
9781 arguments.
9783 2001-08-03 Akim Demaille <akim@epita.fr>
9785 * bin/autoconf.in ($@): Work around the usual sh bug.
9786 From Nicolas Joly.
9788 2001-08-03 Akim Demaille <akim@epita.fr>
9790 Clean up the handling of the M4 builtins tracing exception.
9792 * bin/autom4te.in (Request::request): Don't complete M4 builtins
9793 trace requests.
9794 (@m4_builtins): Rename as...
9795 (@m4_builtin): this.
9796 (%m4_builtin_alternate_name): New.
9797 (&parse_args): Complete the trace requests with alternate names.
9798 (&handle_traces): Hence no longer do it here.
9799 (&trace_requests): Remove, unused.
9801 2001-08-03 Akim Demaille <akim@epita.fr>
9803 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
9804 m4_if, and m4_wrap.

9809 (m4_divert_pop): Dump the whole diversion stack when a diversion
9810 mismatch happens.
9811 * bin/autom4te.in (&handle_output): Remember of the first
9812 occurrence of a possibly undefined macro, not the last.
9813 Complain about the possibly undefined macros in the same order as
9814 the appear in the output.
9815 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
9816 * tests/tools.at (autoconf: forbidden tokens, basic)
9817 (autoconf: forbidden tokens, exceptions): No longer sort
9818 autoconf's stderr, as it is now deterministic.
9819 Check that `dnl' is caught.
9821 2001-08-01 Akim Demaille <akim@epita.fr>
9823 * configure.ac: Bump to 2.52c.
9825 2001-08-01 Akim Demaille <akim@epita.fr>
9827 Version 2.52b.
9829 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.

9841 `END', as `Autom4te::General::END' will be triggered.

9843 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10235 compiler, not the preprocessor.

10278 cross-language link tests can be performed successfully.
10279 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10280 after $LIBS, for consistency; this should be the general rule since
10281 the user may want to link to Fortran libraries that require $FLIBS.
10282 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
10284 2001-06-29 Pavel Roskin <proski@gnu.org>

10287 at-stdout and at-stderr instead of removing the newline
10288 from the echo output, which is not guaranteed to work.
10290 2001-06-28 Jens Petersen <petersen@redhat.com>
10292 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

10351 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
10352 three as failures are unlikely, and speed matters.
10354 2001-06-23 Akim Demaille <akim@epita.fr>
10356 * doc/autoconf.texi (Redefined M4 Macros): New.
10358 2001-06-23 Akim Demaille <akim@epita.fr>
10360 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
10361 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX

10366 * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Defer parsing of
10367 config.status targets to after the evaluation of the INIT-CMDS.
