1 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5 Warn about obsolete install-sh files. Remove stray sentence
6 fragment and fix cross reference.
7 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8 install -d; this undoes the 2006-05-10 change.
9 (MKDIR_P): Mark with AN_MAKEVAR.
10 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11 that we don't require $INSTALL to be thread-safe. Move comments
12 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
13 of AC_PROG_INSTALL. Output a message saying that we're checking
14 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
15 MKDIR_P instead of AC_SUBST.
16 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
17 Special magic for MKDIR_P, too.
18 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
19 a dnl.
20 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
22 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
24 Sync from Automake, as follows:
26 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
27 * config/install-sh: Initialize IFS, so field splitting isn't
28 turned off later.
29 * config/mkinstalldirs: Likewise.
30 * config/missing: Remove superfluous quotes. Replace all uses of
31 `[' by `test', for consistency, and for..
32 * config/missing (sed_minuso, sed_output): New variables.
33 (autom4te, help2man, makeinfo): Use them. Unifies detection of
34 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
35 Fixes `missing' to detect `--output' for help2man. Fixes
36 PR automake/483. Report by Dennis J. Linse.
37 (autom4te): Document in `missing --help'.
39 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
41 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
42 * config/install-sh: Don't use 'path' to talk about file names,
43 as per GNU coding standards. Close a race condition reported by Ralf
44 Wildenhues and Stepan Kasal. There is still a race condition
45 on hosts that predate Posix 1003.1-1992, but we can't help this.
46 Don't mishandle weird characters like space on pre-Posix hosts.
47 Invoke mkdir at most once per dir arg on pre-Posix hosts.
48 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
49 AC_PROG_MKDIR_P from AS_MKDIR_P.
50 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
51 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
52 earlier editions are not (including Automake 1.8.3).
53 Do not suggest mkinstalldirs for thread-safety.
54 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
55 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
56 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
57 presence of special characters and race conditions.
58 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
59 in Autoconf's name space.
61 2006-05-10 Bruno Haible <bruno@clisp.org>
62 and Paul Eggert <eggert@cs.ucla.edu>
64 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
65 from Automake with minor changes.
66 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
68 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
70 * config/install-sh: Update to Automake CVS version, as follows:
71 2006-04-25 Stepan Kasal <kasal@ucw.cz>
72 * lib/install-sh: Simplify the expr implementation of dirname.
73 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
74 * lib/install-sh: Handle --, and diagnose unknown options.
76 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
78 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
79 `./autom4te' to create `./testsuite', since the `all' target
80 will ensure its presence, but `installcheck' should not create
81 the uninstalled wrappers.
83 * tests/torture.at (Unusual Automake input files): Skip if we
84 detect automake < 1.8.
86 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
88 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
89 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
90 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
91 * NEWS: Update.
93 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
95 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
96 munge (multiple) white space and other oddities.
97 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
98 single quotes in variable assignment.
99 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
100 and similar failures by adding multiple spaces, tabs, and other
101 special characters.
102 Report and different test suggested by Francesco Romani
103 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
105 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
106 single quotes, we only need to search for single quotes; this
107 both simplifies the search pattern, and makes us less
108 susceptible to `echo' variations for arguments not containing
109 single quotes.
110 (_AC_ARG_VAR_VALIDATE): Likewise.
112 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
114 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
115 `$*' and IFS concatenation issue with traditional shells and
116 bash-2.04. Report by Seanster@Seanster.com.
118 2006-05-03 Bruno Haible <bruno@clisp.org>
120 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
121 precisely which Mac OS X versions have the od problem.
123 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
125 * doc/autoconf.texi: Use @option systematically.
126 (Integer Overflow):
128 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
129 and Bruno Haible <bruno@clisp.org>
131 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
132 about 'od'.
133 (Integer Overflow): Mention the special case of integer division
134 overflow.
136 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
138 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
139 traditional shells like the Solaris one that do not use the
140 first IFS character for assembling `$*'.
141 Prompted by a related report from autoconf_bug@nro.ca.
143 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
144 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
146 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
147 Mention more problems with the -e option.
149 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
151 * NEWS: Typo.
152 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
154 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
155 in URLs to improve DVI formatted output (requires texinfo 4.6).
156 (System Services, Systemology, Shellology): Likewise.
157 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
158 output.
160 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
161 continuous text.
162 (Runtime): Fix macro argument names to match description:
163 `action-if-found' -> `action-if-true' and similarly.
164 (Obsolete Macros): Likewise.
165 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
166 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
167 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
169 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
171 * doc/autoconf.texi (Limitations of Make): Clean up markup.
173 * ChangeLog: Typo.
174 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
175 DVI output.
177 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
179 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
180 /bin/sh set unsorted output.
181 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
182 * tests/local.at: Likewise.
184 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
186 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
187 (Integer Overflow, Null Pointers, Buffer Overruns):
188 (Floating Point Portability, Exiting Portably): New sections.
189 (Writing Test Programs): Fix some langauge. Recommend exiting
190 with status 1, not merely nonzero. Clarify exit declaration.
191 (Run Time): Move C exit status stuff to new Exiting Portably section.
192 (Systemology): Mention Posix and levenez. Update v7 reference.
193 (Portable Shell): Mention the Posix shell.
195 2006-04-25 Stepan Kasal <kasal@ucw.cz>
197 * bin/autoconf.as (me): Replace by as_me.
199 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
201 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
202 since as_me isn't set yet.
204 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
206 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
207 a few minor bugs in this area.
209 * doc/autoconf.texi (Programming in M4sh): Comment out the
210 documentation of AS_BASENAME, for now.
211 (Shell Substitutions): Do not use AS_DIRNAME in an example.
212 (Limitations of Builtins) <basename>: Do not refer to
213 AS_BASENAME.
214 * bin/autoconf.as (me): Don't use AS_BASENAME.
215 (dir): Remove the unused variable.
216 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
217 AS_DETECT_REQUIRED. All uses changed.
218 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
219 All uses changed.
220 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
221 (AS_BASENAME): Use "basename --" to protect against leading "-".
222 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
223 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
224 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
225 (_AS_DIRNAME_PREPARE): Likewise.
226 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
227 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
228 (AS_DIRNAME): Use "dirname --".
230 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
232 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
233 of "run time" and "run-time" changed to "runtime", for consistency.
234 * lib/autoconf/fortran.m4: Likewise (in comment).
235 * lib/autoconf/functions.m4: Likewise.
236 * lib/autoconf/general.m4: Likewise.
237 * lib/autoconf/headers.m4: Likewise.
239 * doc/autoconf.texi (Run Time): Document the exit status situation
240 with more accuracy and detail.
242 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
244 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
245 Archive is not officially `GNU' any more. Update URL.
246 (Defining Directories): Likewise
247 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
249 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
251 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
252 newline from the `trap' code to finish `config.log'; the NetBSD
253 /bin/sh resets the exit status after an empty command, as
254 documented in doc/autoconf.texi.
255 Reported by Dalibor Topic <robilad@kaffe.org>.
257 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
259 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
260 Suggested by Bruno Haible.
262 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
264 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
265 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
266 Instead, just list the shells that we know work.
267 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
268 changed. Be more cautious about the _cv_ variable.
269 * tests/tools.at (Syntax of the shell scripts): Check the
270 _cv_ variable once, at first, to avoid an internal autoconf error
271 when sh -n does not work.
273 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
275 * lib/Autom4te/FileUtils.pm: Sync from Automake.
277 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
279 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
280 use ">&-" since we're only 99.999% sure that this is portable,
281 and since the MinGW bug is fixed in a different way.
282 * lib/autotest/general.m4 (AT_INIT): Likewise.
284 2006-04-16 Stepan Kasal <kasal@ucw.cz>
286 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
287 before opening config.log, to avoid hitting a bug on MinGW.
289 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
291 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
292 AS_MESSAGE_LOG_FD before reopening it onto the log file.
293 This works around a MinGW bug reported by Eric Paire.
294 Make sure that all writes to the log file append to it,
295 rather than possibly losing data.
296 * lib/autotest/general.m4 (AT_INIT): Likewise.
298 2006-04-14 Stepan Kasal <kasal@ucw.cz>
300 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
301 description.
303 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
305 * NEWS: Update.
307 * configure.ac (AC_INIT): Bump to 2.59d.
309 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
311 Version 2.59c.
313 * Makefile.maint (news-date-check): Do not require a leading `*'
314 before the release date in NEWS.
316 2006-04-12 Stepan Kasal <kasal@ucw.cz>
317 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
319 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
320 the instantiated file do not contain the string 'datarootdir'
321 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
322 @mandir@, replace the reference '${datarootdir}' by the value.
323 * tests/torture.at (datarootdir workaround): New test.
324 * NEWS: Advertise this temporary fixup.
325 Based on a patch by Bruno Haible, reported and analyzed by
326 Paul Eggert and Noah Misch.
328 2006-04-12 Eric Blake <ebb9@byu.net>
330 * tests/autotest.at (Debugging a failed test): Fix comment.
332 2006-04-12 Stepan Kasal <kasal@ucw.cz>
334 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
335 all the changes since 2006-04-07.
337 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
339 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
340 succeeded, but `ln -s file dir' failed, take care to remove the
341 leftover target before the next test, to prevent its spurious
342 failure; also make sure `ln file dir' works before selecting it.
343 Thanks to Keith Marshall for pointing this out.
344 * THANKS: Update.
346 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
347 assignments in `at_debug_args', so that we put them correctly
348 in the `run' script.
349 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
350 Reported by Eric Blake.
352 2006-04-11 Eric Blake <ebb9@byu.net>
354 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
355 top-level tests after micro-suite has been run. Used in...
356 (Debugging a successful test, Debugging script and environment),
357 (Debugging a failed test): ...these new tests. The first of these
358 is fixed by...
359 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
360 macro, split out from...
361 (AT_INIT): ...here, so that using -d also generates a run script.
362 Document that -d inhibits top-level logging.
363 * doc/autoconf.texi (testsuite Invocation): Document that -d only
364 inhibits top-level logging; debug scripts are created.
366 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
367 check.
368 * tests/autotest.at (Empty test, Empty check): New test to check it.
370 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
371 from gcc.
373 2006-04-10 Stepan Kasal <kasal@ucw.cz>
375 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
376 the files if a problem appears. Make the empty *.at files
377 read-only, too. Proposed by Ralf Wildenhues.
379 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
381 * config/Makefile.am: Add comment to force updated Makefile.in.
383 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
384 space only patch to this file, this patch causes the Makefile.in
385 files that include freeze.mk to be updated, and thus have a
386 newer time stamp again, which in turn makes a pristine CVS
387 checkout have correct time stamps.
389 * Makefile.maint (cvs-sv): New macro, to be used..
390 (config.guess-url_prefix, config.sub-url_prefix)
391 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
392 point to CVS text checkout of Gnulib files.
393 (copyright-check): Bump current year.
394 (announcement): Do not hard-wire `./announce-gen'.
395 (cvs-update): Propagate failures of `cvs' and `move-if-change'
396 correctly.
397 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
398 `chmod +x'.
399 (wget_files): Update config.guess, config.sub, texinfo.tex by
400 `wget-update', now that their URLs work again.
402 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
404 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
405 Problem noted by Paul D. Smith.
407 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
409 * doc/autoconf.texi: Remove unused words from word list.
410 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
411 .x-sc_trailing_space: New files.
413 * doc/standards.texi: Sync from gnulib.
415 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
416 `LIBOBJDIR' as experimental.
418 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
419 with a target directory; it's internally implemented as `cp'
420 anyway, but since Autoconf advertises the possibility to use
421 a target directory when LN_S is `ln -s', we need to find out.
422 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
423 analyzed by Keith Marshall <keith.marshall@total.com>.
425 * THANKS: Update.
427 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
429 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
430 confdefs.h as-is. In general, if it has backslash-newline or the
431 like, then it doesn't work either to sort or to remove empty
432 lines.
434 2006-04-09 Stepan Kasal <kasal@ucw.cz>
436 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
438 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
440 * lib/autom4te.in (Automake-preselections): Preselect
441 _AM_SUBST_NOTMAKE.
443 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
445 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
446 apostrophe within a single-quoted string, as this is the usual
447 tradition and is easier to read than '"'"'. Don't rely on the
448 shell treating "$/" like '$/'. Use a more-consistent indenting
449 style for the trap.
451 2006-04-09 Eric Blake <ebb9@byu.net>
453 * tests/autotest.at (Backquote command substitution),
454 (Multiline backquote command substitution): Remove mistaken
455 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
456 applied...
457 (Parenthetical command substitution, Multiline parenthetical
458 command substitution): here.
460 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
462 Import macros from gnulib (often changing their name).
464 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
465 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
466 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
467 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
468 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
469 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
470 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
471 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
472 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
473 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
474 The manual mentions Gnulib more prominently.
475 * doc/autoconf.texi (Gnulib): New node.
476 (Pointers): Add Gnulib URL.
477 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
478 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new

537 Revert the patch from 2006-04-01 and only improve
538 _AS_DETECT_BETTER_SHELL:
540 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
541 skip nonexistent directories.
542 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
543 only shell candidates which exist.

545 * lib/autotest/general.m4 (AT_INIT): No need to give three
546 parameters to _AS_PATH_WALK.
548 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
549 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
551 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
552 distinguish m4sugar macros.
553 * tests/tools.at (autoupdating with aclocal and m4_include):
554 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
555 test case by Noah Misch <noah@cs.caltech.edu>.
557 2006-04-07 Stepan Kasal <kasal@ucw.cz>
559 Revert my change from 2006-03-17, in other words:
560 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
561 and DUALCASE=1.
562 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
563 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
564 it is set.
566 2006-04-07 Eric Blake <ebb9@byu.net>
568 * doc/autoconf.texi (Programming in M4sh): Document that
569 AS_MKDIR_P exits the script on failure.
570 * lib/autotest/general.m4: Remove redundant AS_ERROR.
572 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
574 * config/elisp-comp, config/install-sh, config/mdate-sh,

589 Eric Blake <ebb9@byu.net>,
590 Paul Eggert <eggert@cs.ucla.edu>,
591 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
593 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
594 whether `set' quotes correctly: redirect stderr of the tested
595 `set', and use a subshell, for Ultrix; use `sed' instead of
596 `grep' for zsh `set' which may write binary output; match only
597 at the beginning of a line, to avoid false positives.
598 In order to avoid false positives by unrelated variables with
599 multiline content, put the dump algorithm in a subshell and
600 unset all variables containing newlines (except some which are
601 special to the shell). Warn about cache variables that are
602 unset.
604 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

615 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
616 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
617 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
618 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
620 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
621 shell issue with double-quoted command substitutions of native

647 ac_config_<foo>s again, sometimes normalized, sometimes not.
648 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
649 (AC_CONFIG_COMMANDS): Do not do so here.
650 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
651 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
652 2005-07-25 rewrite. Noticed by Noah Misch.
654 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
655 _AC_PRESERVE_HELP_ORDER, ...
656 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
658 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
659 inside m4_expand_once; it is redundant.
661 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
662 for --help from Cygnus `configure.'
664 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

679 * doc/autoconf.texi (Help Formatting): New node.
680 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
682 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

685 lib/autoconf/specific.m4, lib/autoconf/status.m4,
686 lib/autoconf/types.m4, lib/autotest/general.m4,

694 2006-04-05 Eric Blake <ebb9@byu.net>
696 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
697 empty test suite works.

712 Use simplified args that Eric Blake originally suggested.
714 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
716 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
717 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
718 Use 'comm' rather than N instances of grep; this also fixes a bug
719 whereby substrings were incorrectly matched, causing us to not
720 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
721 (exclude_list): Exclude empty macros.
722 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
724 Use awk rather than grep -E or egrep, to avoid
725 portability problems with regular expressions containing newlines.

727 Switch from grep to awk syntax.
728 (ac_exclude_script): Renamed from ac_exclude_egrep.

737 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
738 report request when we have no AC_PACKAGE_BUGREPORT.
740 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
742 * THANKS: Update.

745 generated files.
747 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
748 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a

751 (_AC_PROG_CC_C99): Likewise.
752 Reported by Albert Chin <china@thewrittenword.com>.
753 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

770 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
772 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
773 to log, point to testsuite output tree.
775 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
777 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
778 * doc/autoconf.texi (Function Portability): Mention that C++
779 has trouble with 'exit'.
780 (Guidelines): Test programs shouldn't use 'exit'.
781 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
782 Remove; all uses removed.
783 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

803 Clean up _AC_COMPILER_EXEEXT* macros.
805 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
806 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
807 ac_file to the name of the default output filei and call
808 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
809 initial `rm' of the candidate files...
810 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
811 the same list in subsequent `rm' calls, and for the temporary
812 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
813 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
814 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
815 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
816 no longer needed) by libtool. Make it a cache check.

818 copied here by mistake.
819 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
820 _AC_COMPILER_EXEEXT.
821 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

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

870 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
872 * bin/autoupdate.in: Redefine m4_location so that warnings print
873 the correct lines of the input file by subtracting..
874 (_au__first_line): ..this new definition.
876 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
877 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
878 Remove stray newline in output.
879 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
880 AC_DEFUN this for autoconf, including the obsoletion diagnose.
881 Fixes autoupdating of code where the replacement output contains
882 m4sugar macros.
883 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
884 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.
885 (au_exclude_list): Add AC_LANG_SAVE.

888 hairy details.
889 The AC_LANG_SAVE issue was reported against Libtool by
890 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
891 Kristian Kvilekval <kris@cs.ucsb.edu>.
893 2006-04-01 Stepan Kasal <kasal@ucw.cz>
895 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
896 switch all of them on and of when necessary. Fixes the bug when
897 m4sugar macros (e.g., m4_define) were expanded after the first
898 automatic update (e.g., after AC_PREREQ or AC_INIT).
900 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

929 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
930 Give an example for AS_DIRNAME instead of referring to Posix..
931 (File System Conventions): Put discussion of // versus / here, and
932 modernize it a bit.
933 (Limitations of Usual Tools): Add basename. Remove verbiage

1448 (Limitations of Usual Tools): Document the weird restrictions
1449 that Posix has about { }. Use better quoting.

1537 Factor functionality to..
1538 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
1539 `AC_SUBST($1)' in the public version.
1540 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
1541 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

1594 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1595 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1596 by the function rather than ignoring it.
1597 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1598 comparing its address. Intel's interprocedural optimization was
1599 outsmarting the old heuristic. Problem reported by
1600 Mikulas Patocka.

1604 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

1611 2005-10-04 Stepan Kasal <kasal@ucw.cz>
1613 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
1614 before removing it (chmod -R u+rwx); there are three instances of this.
1616 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1617 Stepan Kasal <kasal@ucw.cz>
1619 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1620 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1621 make its content writable before removing it. Remove an errorneous
1622 comment from the end, where the logs of the failed tests are copied
1623 to the main log file.
1625 2005-09-27 Stepan Kasal <kasal@ucw.cz>
1627 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
1628 in case the computer is too quick. Double quote the configure.ac
1629 snippets.
1631 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
1632 problems if the testsuite were running too fast.
1634 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1636 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1637 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1638 (which belong to Xt, not X itself). See Debian bug 327655.
1639 * NEWS: Mention this.
1641 2005-09-07 Stepan Kasal <kasal@ucw.cz>
1643 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
1645 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
1647 * config/move-if-change: Don't output "$2 is unchanged";
1648 suggested by Ben Elliston. Handle weird characters correctly.
1650 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1652 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1653 calls, so that the final expansion of this macro is shorter.
1654 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1655 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1656 the cleanup there. Use AS_VAR_* macros, to be more general.
1657 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1659 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1661 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
1663 2005-09-01 Stepan Kasal <kasal@ucw.cz>
1665 * doc/autoconf.texi (Configuration Headers): Add an index entry
1666 for AH_HEADER.
1668 2005-08-26 Pavel Roskin <proski@gnu.org>
1670 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
1671 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
1672 running xmkmf.
1674 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1676 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1677 The previous patch didn't work, so try a better one.
1679 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1681 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1682 in the example. Reported by Bruno Haible.
1683 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1684 "if $undefined_var;" succeeds with my shell.
1686 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1687 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1688 but change the m4_divert_text to m4_divert_once.
1690 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1692 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1693 Work around bug in Solaris /usr/xpg4/bin/awk.
1694 The bug is present in at least Solaris 8 through 10.
1696 2005-08-24 Stepan Kasal <kasal@ucw.cz>
1698 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
1699 some evil values and relying on the fact that $* concatenates the
1700 parameters by the first character from IFS.
1702 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1703 Stepan Kasal <kasal@ucw.cz>
1705 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
1706 first header appears, define AH_HEADER.
1707 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1708 Update limitations about when to call AC_CONFIG_HEADERS.
1709 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1710 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1711 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1712 ``Configuration Actions''; fix their index entries.
1714 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1715 options correctly. Process N-M as M-N if M is smaller than N.
1716 Process ranges correctly so that N-N will run only N.
1717 Sort and uniquify the tests that will be run. If there is more
1718 than one test, reinsert the banners for the tests.
1719 * tests/autotest.at (Keywords): Unmark XFAIL.
1721 2005-08-23 Stepan Kasal <kasal@ucw.cz>
1723 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
1724 before passing the macro name to AH_TEMPLATE.
1726 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1727 now opens log after option processing; in particular, --version
1728 and --help do not touch config.log.
1730 * Makefile.maint: Revert the change from 2005-08-12.
1732 2005-08-22 Stepan Kasal <kasal@ucw.cz>

1738 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1740 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
1741 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
1742 Language cleanup.
1744 * doc/autoconf.texi (Defining Symbols, Changed Results):
1745 Prepend to LIBS, not append, in examples.
1747 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1749 When building in place, set srcdir="."; suggested by Tim Van Holder.
1751 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1752 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1753 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1754 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
1755 does not mean "no --srcdir option".
1757 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1759 * tests/autoscan.at (autoscan): New file.
1760 * tests/suite.at: Use it.
1761 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
1762 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
1764 * tests/autotest.at (Keywords): Test keywords combinations.
1766 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1768 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1769 add "2>&1"; gzip 1.2.4 prints help on stderr.
1771 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1773 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1774 was pushdef'ed twice while popped only once. Push it only once.
1775 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
1777 2005-07-26 Stepan Kasal <kasal@ucw.cz>
1779 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

1784 * Makefile.maint: Update from Bison.
1786 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
1787 "<tab>" in comment, so that the point is understandable.
1789 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1791 Rewrite substantial part of lib/autoconf/status.m4.
1792 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1793 and CONFIG_COMMANDS are not processed in four separate loops.
1794 Instead, there is one main loop. This alows that the common code
1795 is expanded only once, thus config.status (and configure) is smaller.
1797 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1798 the AC_LIST_FILES and cousins macros are no longer used.
1800 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1801 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1802 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1803 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1804 contain the initialization, nor the for loop, nor the associated
1805 commands; all these go to ...
1806 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1807 _AC_OUTPUT_CONFIG_STATUS.
1808 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1809 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1810 (_AC_OUTPUT_FILE): The creation of the sed script ...
1811 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1812 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1813 _AC_OUTPUT_MAIN_LOOP.
1814 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1815 _AC_CONFIG_COMMANDS): Use ...
1816 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1817 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1818 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1819 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1820 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1821 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1822 ... new macros.
1823 (_AC_CONFIG_UNIQUE): Update.
1824 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1825 Replaced by this ...
1826 (_AC_LIST_TAGS): ... new common macro.
1827 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1828 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1829 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1830 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1831 this didn't belong to the `config commands' section.
1832 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1833 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1834 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1835 to the `config commands' section either.
1836 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1837 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1839 ... and many changes to the comments nearby.
1841 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1842 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1843 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1844 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1845 (#define header templates): The comment at the top of the generated
1846 header now includes the name(s) of the source file(s).
1848 Several unrelated small changes:
1850 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1851 parameter to AC_DIAGNOSE.
1852 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1853 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1854 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1855 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1856 with AU::AC_OUTPUT.
1857 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

1954 configure_input, top_builddir, srcdir, etc.
1955 * lib/autotest/general.m4 (AT_INIT): Likewise, for
1956 PATH_SEPARATOR in AUTOTEST_PATH.

2025 addition.
2027 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2049 because we really don't support spaces and suchlike in dir names.
2050 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2051 Don't worry about backslashes in srcdir; it can't happen now.

2080 (Special Shell Variables): Fix sed code this in the example.
2081 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2082 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2084 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

2095 * doc/autoconf.texi:
2096 Don't mention Solaris versions so much, if a
2097 problem is common to all extant versions of Solaris. Say "SunOS
2098 4" instead of "SunOS" for SunOS 4.
2099 (awk): Mention more of the limitations of traditional Awk.
2100 (cat): Don't talk about cat -v.

2133 quotes and backslashes. Patch from Derek Price.

2144 Problem reported by Ralf Menzel.
2146 2005-06-08 Derek Price <derek@ximbiot.com>
2148 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2149 renaming them since they are about to be redefined anyhow.

2160 * doc/autoconf.texi (Introduction): Likewise.
2161 Reword to avoid some formatting glitches.

2164 Redo example output tp match current CVS snapshot.
2165 Use @example.org in email addresses when the examples
2166 might get inadvertently cut-and-pasted into user code.
2167 Remove example of autom4te usage that doesn't seem to work now.
2168 Use modern AC_INIT (except when the example is meant to be
2169 shown with Autoconf 2.13).
2170 Update ksh info for Solaris 9 and later.
2171 KB -> kB.

2183 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2184 Tru64 ksh pattern matching bug. Reported against Libtool by
2185 Albert Chin <libtool@mlists.thewrittenword.com> and
2186 Nicolas Joly <njoly@pasteur.fr>.
2188 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2190 m4_cdr of one-member list was [[]] (one-member list containing an
2191 empty string) instead of [] (an empty list. Callers were skewed to
2192 match this misbehaviour. As a consequence of this:
2193 - m4_foreach([x], [], [foo]) expanded to `foo', while
2194 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2195 This bug has been fixed:
2197 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2198 expand to an empty string; print error msg if called without
2199 an argument list.
2200 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2201 misbehaviour; handle [] and [[]] correctly.

2211 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2212 swallow records with more than 99 fields.
2213 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2214 parse the long line.
2216 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2218 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

2251 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2253 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2254 now contain newlines, and substituted files must be referenced on
2255 a line alone; the sed scripts to substitute them are now very
2256 different.

2274 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2276 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

2310 (ac_top_build_prefix): ... to this; the old name is also kept, for
2311 backward compatibility.

2317 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2318 at_top_builddir to at_top_build_prefix.
2319 * lib/autotest/general.m4 (AT_INIT): Likewise.
2321 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2323 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2324 of confdefs.h .
2326 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2328 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2329 argument to m4_foreach. I guess it was necessary in the past,
2330 but I think it's a no-op now.
2332 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2334 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2335 ``cat <<_ACEOF'' commands to one.
2336 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2337 * lib/autoconf/status.m4: On various places, use expr instead of
2338 ``echo|sed.''
2339 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2340 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2341 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2342 a range.
2343 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2344 the wrong patterns between ``case'' and ``esac.'' The previous
2345 code had false positives.
2347 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2349 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2350 as on 2005-05-02.
2351 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2352 Mention LIBOBJDIR.

2390 Update FSF postal mail address.
2392 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2394 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2395 check.
2396 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2397 enough arguments, similarly as in m4_bpatsubsts.
2399 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2401 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2402 of absolute paths.
2404 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2406 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2407 for absolute directory names in one loop.
2408 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2409 abbreviations of --version and --debug.
2411 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2413 * doc/autoconf.texi (Autoconf Language): Be more precise about
2414 quoting rules. Problems noted by Stepan Kasal.
2415 Also, throughout this document, be more careful about white space.
2416 "blank", "white space", and "space" all have different meanings
2417 and we should be careful to say what we mean.
2419 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2421 Fix C++ related problems reported by Werner Lemberg.
2422 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2423 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2424 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2425 avoid problems with C++ and throw.
2426 * tests/compile.at: .cpp, not .cc.
2428 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2430 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2432 * doc/autoconf.texi (Generic Functions): Typos.
2434 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2436 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2437 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2438 set by latest automake.
2440 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2442 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2443 outputs 0 on GNU/Linux these days.
2445 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2447 * doc/autoconf.texi (Autoconf Language): Add more description
2448 about quoting heuristics.
2449 (Limitations of Builtins): Describe "set -" problems.
2451 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2453 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2454 not newline.
2456 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2457 by AC_DEFINE; it was a mistake.
2458 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2460 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2462 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2464 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2466 * doc/autoconf.texi (External Software): Quadrigraphs are not
2467 processed correctly in AS_HELP_STRING; avoid this in the examples.
2468 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2469 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2470 comment and reduce m4_default([foo], []) to [foo].
2471 (m4_strip): Update the explanation.
2473 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2475 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2476 Remove core.conftest.* too; it's generated by Tru64 5.1.
2477 Problem reported by Jennis Pruett.
2478 * lib/autoconf/functions.m4
2479 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2480 Don't bother to remove core files; AC_RUN_IFELSE should do that
2481 for you.
2483 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2485 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2487 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
2489 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

2492 2005-04-15 Stepan Kasal <kasal@ucw.cz>
2494 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
2495 the comment.
2497 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
2499 * doc/autoconf.texi (External Software, Package Options): Add
2500 examples showing how to implement --with-* and --enable-* options.
2502 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2504 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2505 as well as configure.in. Problem reported by Gregorio Guidi.
2507 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2509 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2510 pattern for alloca snippet.
2512 2005-04-04 Stepan Kasal <kasal@ucw.cz>
2514 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
2516 2005-04-01 Stepan Kasal <kasal@ucw.cz>
2518 * doc/autoconf.texi (Generic Programs): Fix a typo.
2520 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2522 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2523 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2525 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2527 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2528 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2529 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2530 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2531 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2533 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2535 * NEWS: The configure command now warns you if you attempt to use
2536 a directory whose name contains a special character like space,
2537 newline, or "\".
2538 * doc/autoconf.texi (Installation Directory Variables): Allow
2539 "," in file names. Do not use \@; it's not a portable regexp.
2540 * bin/Makefile.am (edit): Likewise.
2541 * lib/Makefile.am (edit): Likewise.
2542 * tests/Makefile.am (edit): Likewise.
2543 * tests/semantics.at: Likewise.
2544 * tests/torture.at: Likewise.
2545 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2546 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2547 * doc/autoconf.texi (File System Conventions): Warn about
2548 unportable file names.
2549 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2550 (AC_INIT): Use it.
2551 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2552 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2553 ac_pwd, and quote srcdir.
2554 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2556 * doc/autoconf.texi: Fix some systematic formatting problems.
2557 ".)" needs a following @: if not at the end of a sentence, and
2558 similarly for "!)". "etc." should be preceded by a comma.
2559 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2561 2005-03-22 Bruno Haible <bruno@clisp.org>
2563 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2564 argument is often called 'build-aux'.
2566 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2568 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2569 macro AC_TRY_LINK is obsolete.
2570 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2571 `AC_CONFIG_FILES'.
2573 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2575 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2576 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2577 from a Common Lisp's `cl'.
2578 (AC_PROG_CXX): Behave according to the documentation: don't
2579 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2580 make the variable CCC precious; use `cl.exe', not `cl'.
2582 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2583 Alexandre Duret-Lutz <adl@gnu.org>
2585 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2586 /dev/null, as "configure" shouldn't read stdin, and this insulates
2587 us from problems (e.g., when testing for "cl"). Also, do this
2588 redirection before invoking "hostname" or "uname", and keep the
2589 original input stream available via...
2590 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2591 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2592 bother with "</dev/null" since it's now done at the top of
2593 'configure'.
2594 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2595 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2596 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2597 * doc/autoconf.texi (File Descriptor Macros): New section.
2598 (Printing Messages): Mention it.
2599 * tests/base.at (Input/Output): New test.
2601 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2603 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2604 newline if neither \c nor -n work, as that would output two
2605 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2607 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2609 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2610 This causes that any required macros inside will get before the if.
2611 * doc/autoconf.texi (autom4te.cache): A typo.
2613 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2615 Undo previous change, except keep the change to
2616 lib/autoconf/programs.m4 that replaced grep with shell
2617 pattern-matching. This is because net-snmp configure reads stdin.
2618 Reported by Noah Misch.
2620 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2622 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2623 from /dev/null, as "configure" shouldn't read stdin, and this
2624 insulates us from problems (e.g., when testing for "cl").
2625 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2626 before invoking "hostname" or "uname".
2627 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2628 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2629 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2630 "</dev/null" since it's now done at the top of 'configure'.
2631 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2632 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2633 Also, replace grep with shell pattern-matching, to save a process.
2635 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2637 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2638 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2639 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2640 compiler.
2642 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2644 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2645 grep -q isn't portable. Improve grep -s explanation.
2646 Problem reported by Dan Manthey.
2648 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2650 * doc/autoconf.texi (Special Shell Variables): Clarify
2651 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2653 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2655 * doc/autoconf.texi: Use @acronym for DJGPP.
2656 Fix some @code's that should have been @env's, and vice versa.
2657 Sort environment variable names.
2658 Mention that shells no longer inherit IFS.
2659 Don't recommend PATH_SEPARATOR=';' so strongly.
2660 Mention that $RANDOM might expand to the empty string.
2661 "symlink" and "soft link" -> "symbolic link".
2662 Improve mktemp description (reported by Bruno Haible).
2664 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2666 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2667 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2668 Likewise.
2669 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2670 Likewise.
2672 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2674 * NEWS: Mention AT_COPYRIGHT.
2676 * tests/local.at (AT_CMP): Use diff directly on input files rather
2677 than copying them.
2679 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
2680 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
2682 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2683 and Paul Eggert <eggert@cs.ucla.edu>
2685 * tests/autotest.at (Empty test suite): New test.
2686 * tests/torture.at (Substitute and define special characters)
2687 (Substitute a 2000-byte string, Define to a 2000-byte string)
2688 (Substitute a newline, Define a newline): New tests.
2690 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2692 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
2693 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
2694 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
2695 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
2696 (Standard regular expressions): New test.
2697 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
2698 excess test name quoting.
2699 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
2700 CPPFLAGS to `configure' instead of setting it in `configure'.
2702 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
2703 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
2704 on some platforms.
2706 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
2707 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
2709 * tests/local.at (AT_CMP): New macro.
2710 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
2711 (AC_SAVE_STATE): Move environment grep...
2712 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
2713 (AT_CONFIG_CMP): New macro.
2714 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
2715 * tests/c.at (Extensions): Do not exit early.
2716 * tests/atlocal.in: Inherit $GREP.
2718 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
2719 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
2721 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
2722 (AC_COPYRIGHT): Factor header comment portion out and move into...
2723 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
2724 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
2725 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
2726 --version output.
2727 * tests/local.at: Add Autoconf test suite copyright notice.
2728 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
2730 2005-02-04 Bruno Haible <bruno@clisp.org>
2731 and Paul Eggert <eggert@cs.ucla.edu>
2733 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
2735 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
2737 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
2738 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2740 Try not to generated lines of unlimited length, as POSIX places a
2741 2047-byte limit on line length of portable text files.
2742 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2743 Use newline as a separator, not space.
2744 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.

2801 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2802 Update the long comment explaining it.
2804 m4_require no longer writes an ``is required by'' line to the
2805 execution stack. It contains only one bit of non-redundant
2806 information: that the macro was required, not called. And even
2807 this bit is useless in most situations: have you ever met a macro
2808 which both calls and requires the same macro?
2810 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2811 (_m4_defun_pro_outer): ... only via this macro, for the outermost

2819 * tests/m4sugar.at (m4_require): Expect output without the
2820 ``is required by'' messages.
2822 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2824 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2825 rather than x for expr.
2827 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2828 this is safe.
2829 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2830 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2856 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2858 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2859 Warn about newline stripping in `` and $(). Update Solaris
2860 version to 9.
2861 (Limitations of Builtins): Use expr "X...", not expr "x...", as

2863 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
2864 stripping.
2866 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2886 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
2888 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2890 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

2914 otherwise.
2915 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
2916 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
2917 stored in _m4_divert_diversion or _m4_divert_dump.
2918 (m4_divert_pop): When the parameter is given, compare the symbolic
2919 name with the last diversion pushed on the stack. Previously, the
2920 current diversion was compared with the numeric value of the
2921 diversion given as the parameter.
2922 (m4_require): If the macro hasn't been expanded yet, call ...
2923 (_m4_require_call): this new macro.

2956 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3206 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
3207 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
3209 2004-12-07 Stepan Kasal <kasal@ucw.cz>
3211 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
3212 patch: extra "-l"s.
3214 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
3216 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
3217 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
3218 * doc/autoconf.texi (Particular Functions): Mention new behavior.
3220 2004-12-03 Stepan Kasal <kasal@ucw.cz>
3222 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
3223 out the common code to ...
3224 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
3225 value of the #define--default to 1, iff the macro was called
3226 with exactly one parameter.
3228 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3230 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3231 "char c = '\200';" rather than "char c = 0x80;" as the
3232 latter doesn't conform to the strict C standard due to
3233 overflow on signed char hosts.
3235 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3236 to -qlanglvl=ansi. We don't want to disable extensions.
3238 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
3240 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
3241 (Using Autotest, testsuite Scripts, Writing testsuite.at):
3242 Reword slightly to avoid some English-language problems noted

3256 Automake (not without Autoconf).
3257 (Introduction): Mention lists.gnu.org.
3258 * BUGS: Don't mention bugs.gnu.org.
3259 Remove mention of ancient libtool compatibility problem.
3260 * NEWS: Mention that bugs.gnu.org is kaput.
3261 * README: Likewise. Mention where mailing list archives can be found.
3263 2004-11-28 Stepan Kasal <kasal@ucw.cz>
3265 * HACKING: Refer to "coreutils", not "File, Shell or Text utils".

3284 in my editing of the previous patch. Problem reported
3285 by Alexandre Duret-Lutz.
3287 2004-11-22 Stepan Kasal <kasal@ucw.cz>
3289 * doc/autoconf.texi (Autoconf Language): Explain that
3290 ``descriptions'' may not be double quotes.
3291 (Quotation Rule Of Thumb): Likewise.
3292 (Pretty Help Strings): Likewise; remove the wrong comment;
3293 simplify the examples and improve their quoting.
3295 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3297 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3298 the $1_found variable, don't test whether the file is executable;
3299 Both things are checked ...
3300 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3301 the former ``test -f''.
3302 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
3304 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
3306 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
3307 use cp -R instead.
3309 2004-11-10 Derek R. Price <derek@ximbiot.com>
3311 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
3312 limitations. Reorder paragraphs for clarity.
3314 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3316 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
3317 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
3318 variants", "Unix", and some related minor wording fixups.
3320 (Shellology, Special Shell Variables): Document that the Zsh
3321 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
3322 to Alexandre Duret-Lutz for this info.

3333 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
3335 * doc/autoconf.texi (auindex): New macro.
3336 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3337 Problem reported by Stepan Kasal.
3339 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3341 Fix problems reported by Andreas Buening in:
3342 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3343 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3344 in test makefile.
3345 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3346 readable; it's not true in OS/2-emx.
3348 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3350 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3351 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3352 (trivial change). Problem and patch reported by Andrew Church in:
3353 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3355 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
3357 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
3358 three args in examples. Problem reported by Frederik Fouvry in:
3359 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
3360 Also, fix some minor spacing and punctuation bugs.
3362 2004-09-02 Akim Demaille <akim@epita.fr>
3364 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
3365 "case" to restore ordering.
3366 Reported by Stepan Kasal.
3368 2004-08-26 Akim Demaille <akim@epita.fr>

3376 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
3378 Version 2.59b.
3380 * README: Add advice about m4 1.4.2.
3382 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3383 texinfo.tex for now (done by hand now).
3384 * Makefile.maint (wget_files, cvs_files):
3385 Remove ansi2knr.c; nobody uses it.
3386 (ansi2knr.c-url_prefix): Remove.
3387 (cvs-update): Fix test for failure. I don't know why it ever
3388 worked...
3390 * doc/autoconf.texi: Update URLs, some of which went stale.
3391 Use @uref rather than @href.
3393 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3394 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3396 * config/config.guess, config/config.sub, config/elisp-comp,
3397 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3398 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3400 * NEWS, TODO, configure.ac, bin/autoscan.in,
3401 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3402 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3406 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3407 tests/tools.at, tests/torture.at:
3408 Use "file name" rather than "filename" or "path",
3409 to be consistent with the terminology of the GNU coding standards.
3411 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3413 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3414 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3415 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3416 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3418 More fixes to support spaces in the name of the build directory.
3419 This isn't a complete fix but it's an improvement.
3421 * bin/autoconf.as (autom4te_options): New var.
3422 Use it instead of appending to AUTOM4TE, so that we can allow
3423 spaces in the build directory's absolute name.
3424 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3425 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3426 AT_CHECK_NOESCAPE): Likewise.
3427 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3428 main program): Likewise.
3430 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3432 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
3433 From Ralf Corsepius in:
3434 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
3436 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3438 * doc/autoconf.texi (Function Portability): Document isinf and
3439 and isnan. From a suggestion by Kevin Ryde.
3441 * lib/Autom4te/General.pm (END): Return correct exit status even
3442 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3444 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3446 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3447 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3448 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3450 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3452 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3453 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3454 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3455 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3456 * lib/autom4te.in (Automake-preselections): Preselect
3457 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3459 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3461 * lib/autom4te.in (Automake-preselections): Preselect
3462 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3463 trace them.
3465 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3467 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3468 Tru64.
3469 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3470 Document problem with "`""`" in pdksh POSIX mode.
3472 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3474 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3475 with pdksh, too. Problem reported by Patrick Welche via
3476 Gary V. Vaughan.
3477 * doc/autoconf.texi (Shellology): Note that set -o posix is
3478 useful for pkdsh, too.
3480 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3482 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3483 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3484 Don't fail if ENV or BASH_ENV is readonly.
3485 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3486 etc. are read only. Problem reported by Ludovic Courtes.
3488 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3490 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3491 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3492 (trivial change)
3494 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3496 * doc/autoconf.texi (File System Conventions): Warn about
3497 names like "aux". Problem reported by Eric Blake.
3499 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3500 by zero instead of array size, so that we can use any arithmetic
3501 constant expression (instead of requiring an integer constant
3502 expression). This allows us to test expressions like DBL_MAX <
3503 LDBL_MAX, which didn't conform to the C standard using the old
3504 method.
3505 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3506 now that we can do floating-point tests at compile time.
3508 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3510 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3511 and LDBL_EPSILON, as the resulting expression isn't an
3512 integer constant expression and violates the C standard.
3513 Problem reported by Nelson H. F. Beebe. Also, check
3514 for "L" suffix, and check that long double doesn't have
3515 worse range or precision than double, that mixed-mode
3516 arithmetic doesn't generate a diagnostic, that double
3517 constants fit in long double.
3519 2004-06-03 Kevin Ryde <user42@zip.com.au>
3521 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3522 malloc(0) and realloc(NULL,size).
3524 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3525 Bob Proulx.
3527 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3529 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3530 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3531 by Jim Meyering.
3533 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3535 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3536 can be rewritten using if-then-else. Suggested by Bruno Haible.
3538 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3540 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3541 Problem reported by Stepan Kasal.
3543 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3545 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3546 change). Patch reported by Ralf Wildenhues in
3547 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3549 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3550 function F exists if the compiler and linker let you compile an
3551 expression like (F != 0). Recent versions of GCC optimize away
3552 the reference to F in that case, since every function address must
3553 be nonzero, so the link succeeds even if F does not exist.
3554 Problem reported by Manu in
3555 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3557 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3558 "Unix". Many uses changed.
3559 (Limitations of Builtins): Explain better why the ! command isn't
3560 portable.
3562 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3564 * lib/autom4te.in (Automake-preselections): Preselect
3565 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3567 2004-05-19 Kevin Ryde <user42@zip.com.au>
3569 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3570 referencing AC_FUNC_STRERROR_R.
3572 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3573 note pessimistic assumption when cross compiling.
3575 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3577 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3578 (until 2004) invoked subcommands with sh -e, contra POSIX.
3579 Reported by Kevin Ryde.
3581 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3583 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3584 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3585 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3586 `test -f " /usr/bin/grep"', which _always_ failed.
3587 (AC_PROG_SED): Ditto bogus PATH fix.
3588 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3589 requires that grep correctly supports _multiple_ `-e' options, rather
3590 than stating only that grep should accept `-e'.
3592 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3594 Port to C99, which requires that 'exit' be declared.
3596 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3597 to ensure that stdlib.h is included.
3598 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3599 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3600 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3601 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3602 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3603 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3604 when using 'exit' in a test; C99 requires that 'exit' be declared.
3606 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3608 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3609 now prefers 'grep' implementations that accept -e.
3610 (Limitations of Usual Tools): Describe problems of traditional
3611 egrep and fgrep with long input lines, and of traditional grep
3612 with -e.
3613 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3614 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3615 All callers changed. Append /usr/xpg4/bin to the PATH, for
3616 Solaris.
3617 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3618 the user with complaints about multiple -e options.
3619 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3620 Define it with AC_PROG_GREP.
3621 * configure.ac (AC_PROG_GREP): Add.
3622 * lib/freeze.mk (GREP): New macro.
3624 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3626 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3627 a possible candidate only after all others fail, rather than
3628 consulting it first. This improves backward compatibility by
3629 better reflecting the way shell selection occurred in previous
3630 versions of Autoconf, and should help to avoid triggering latent
3631 problems in other packages, such as the one in Automake where zsh
3632 is not handled robustly:
3633 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3634 Although it is not Autoconf's responsibility to work around
3635 problems in Automake, it nevertheless makes sense to avoid
3636 introducing unnecessary incompatibilites.
3638 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3639 Gary V. Vaughan <gary@gnu.org>
3641 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3642 how deeply nested we are when a suitable tool is found, set the
3643 ac_path_TOOL_found flag.
3644 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3645 nested we are in this macro. Break out of all 3 nested loops if
3646 ac_path_TOOL_found is set.
3648 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3650 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3651 of the _AS_PATH_WALK loop too if GNU flavor is found.
3653 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3655 * doc/autoconf.texi (Limitations of Make): Update documentation
3656 for `$<'. New entry `Long lines', based on a report from Simon
3657 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3658 paragraph about DJGPP, based on a mail from Richard Dawe.
3660 2004-04-20 Paul Eggert <eggert@twinsun.com>
3662 * tests/c.at (C keywords): Don't assume that GCC supports
3663 "restrict" and "inline", as sufficiently-old GCC versions do not
3664 (also, GCC configured to be in pedantic C89 mode does not).
3665 Problem reported by Sumit Pandya in:
3666 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3668 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3669 consider -g to work if it generates warnings when plain compiles
3670 don't. Problem reported by Braden McDaniel in:
3671 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3673 * doc/autoconf.texi (Slashes): New section, to document a problem

3682 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3684 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3685 best tool so far counter rely on the tool path variable name to
3686 avoid checks for one tool being affected by the results of running
3687 the length check on a previous tool.
3689 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3690 match expression argument, as different greps have different
3691 regular expression flavours.
3692 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3693 literals.
3694 (AC_PROG_EGREP): Pass 'EGREP$'.
3695 (AC_PROG_GREP): Pass 'GREP$'.
3697 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3699 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3700 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

3704 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3705 Types, Specific Compiler Characteristics, System Services,
3706 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3707 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3708 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3709 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

3720 2004-03-28 Paul Eggert <eggert@twinsun.com>
3722 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3723 now defines HAVE_DECL_TZNAME if it is declared, when
3724 HAVE_STRUCT_TM_TM_ZONE is not defined.
3725 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3726 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3727 for HAVE_TZNAME.
3729 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3731 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
3732 superfluous backslashing of quotes (") in sed expressions;

3735 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
3737 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
3738 Fortran compiler is ifort, also added pghpf; thanks to Nelson
3739 H. F. Beebe for the bug report.
3741 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3743 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3744 quoted -cmdline argument in Portland Group compiler (bug
3745 reported by Jeffrey J. Barteet).
3747 2004-03-25 Kevin Ryde <user42@zip.com.au>
3749 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
3750 (Run Time): ... here, where it's now mentioned.

3754 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
3755 inherits from language Autoconf-without-aclocal-m4.
3756 (Customizing autom4te): Adjust example; the cache must now be
3757 disabled for language Autoconf-without-aclocal-m4.
3759 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
3760 Nathanael Nerode <neroden@twcny.rr.com>

3771 AC_CHECK_TOOLS.
3772 (Specifying Names): Document the reason for these future
3773 behavioral changes.
3774 * tests/mktests.sh: Do not generate tests for the
3775 new macros.
3776 * NEWS: Document these changes.
3778 * doc/autoconf.texi: Avoid macros with unbraced arguments,
3779 they make TeX hang up.
3781 2004-03-15 Paul Eggert <eggert@bogus.example.com>
3783 * NEWS: New macro AC_CHECK_ALIGNOF.
3784 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3785 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3786 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3787 vowel.
3788 (AC_CHECK_ALIGNOF): New macro.
3789 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
3790 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to

3793 2004-03-03 Paul Eggert <eggert@twinsun.com>
3795 * bin/Makefile.am (edit): Don't use $< in a context where
3796 POSIX doesn't require support for it. Use $@.in instead.
3797 Problem reported by Anthony N. Frasso in
3798 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3799 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3801 2004-02-23 Gary V. Vaughan <gary@gnu.org>
3803 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
3804 from the next generation of Libtool.
3805 * lib/autom4te.in (Autoreconf-preselections): Ditto.
3807 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3809 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
3810 is not always thread-safe. Report from Nathanael Nerode.
3812 2004-02-18 Paul Eggert <eggert@twinsun.com>
3814 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3815 problem on QNX reported by Stephen Rasku in
3816 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3818 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
3819 $(m4sh_m4f_dependencies); this removes a FIXME.
3820 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
3821 (MAINTAINERCLEANFILES): Split into pieces,
3822 one per related section. Add $(srcdir)/wrapper.in.
3824 2004-02-09 Paul Eggert <eggert@twinsun.com>
3826 * doc/autoconf.texi (Setting Output Variables): Emphasize that
3827 AC_SUBST provides no portable way to escape literal newlines.
3829 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3830 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3831 Darwin uses -lcrt2.o and there's little point to cataloging all
3832 the system variants. Partial fix reported by Andreas Waechter in:
3833 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
3834 for bug reported by Nelson H. F. Beebe in:

3840 suggested by Paul Eggert.
3841 * lib/autoconf/autoupdate.m4: Correct reference to
3842 acobsolete.m4, suggested by Alexandre Duret-Lutz.
3844 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

3847 refer to the correct file.
3848 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
3849 the behavior of the third argument.
3850 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
3851 correctly the behavior of the third argument. Document
3852 what the three macros that AU_DEFUN defines do. Fix
3853 warning message when the third argument includes $0
3854 (reported by Alexandre Duret-Lutz).
3856 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3857 Eric Sunshine <sunshine@sunshineco.com>
3858 Paul Eggert <eggert@twinsun.com>
3860 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
3861 (AS_INIT): Output shell initialization there. Removed optional
3862 parameter. Expand _AS_SHELL_FN_SPY.
3863 (AS_INIT_WITH_SHELL_FN): Removed.
3864 (_AS_SHELL_FN_SPY): New macro.
3865 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3866 macros.
3867 (AS_SHELL_SANITIZE): Remove loop to find better shell
3868 and documentation for the parameter.
3869 (_AS_DETECT_BETTER_SHELL): Move it here.

3871 (_AS_RUN): Move it here, support testing with eval.
3872 (AS_REQUIRE_SHELL_FN): Require shell functions when
3873 it is used.
3874 (_AS_LINENO_WORKS): Put around braces, we do not
3875 trigger the bash bug anymore.
3876 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3877 use AS_INIT_WITH_SHELL_FN.
3878 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3880 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3882 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
3883 * doc/autoconf.texi: Don't say that the third parameter
3884 is broken.
3885 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
3886 (AU_DEFUN): Honor the third parameter, create autoupdate
3887 macros with AU_DEFINE.
3888 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
3889 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

3891 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
3892 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

3897 * lib/autoconf/status.m4: Remove FIXME.
3898 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
3899 that the macro is not present anymore in the updated
3900 configure.ac.

3908 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
3909 2003 (except 1997) to the list of copyright years. This undoes
3910 the 2003-05-22 change, which removed the older years from the list.
3911 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
3913 2004-01-27 Gary V. Vaughan <gary@gnu.org>
3914 Albert Chin-A-Young <china@thewrittenword.com>

3917 grep or ggrep program in PATH that accepts as long lines as
3918 possible.
3919 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
3920 AC_PROG_GREP.
3921 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
3922 egrep and fgrep respectively if $GREP -E/-F don't work.
3923 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
3924 _AC_PROG_GREP, and AC_PROG_SED.
3925 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
3926 longest input length accepted by a command.
3927 (AC_PROG_SED): Use it.
3928 * doc/autoconf.texi (Particular Programs): Document the changes.
3929 * NEWS: Updated.
3931 2004-01-27 Paul Eggert <eggert@twinsun.com>

3953 sources.
3955 2004-01-26 Paul Eggert <eggert@twinsun.com>
3957 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
3958 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
3959 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
3960 not <inttypes.h>. Problem reported by Tim Mooney in
3961 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
3962 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
3963 Likewise.
3965 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
3966 otherwise "make check" fails because it forbids cmp (I guess
3967 because cmp treats files as binary on DOS-like systems).
3969 * tests/mktests.sh: Update copyright date to 2004, since some tests
3970 have changed in 2004.
3972 2004-01-23 Gary V. Vaughan <gary@gnu.org>
3974 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
3975 non-truncating sed or gsed program in PATH.
3976 * tests/acprograms.at: Add it.
3977 * doc/autoconf.texi (Particular Programs): Document it.
3978 * NEWS: Updated.
3980 2004-01-15 Paul Eggert <eggert@twinsun.com>
3982 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
3983 -std1 disables some useful extensions on Tru64. Problem reported
3984 by N. Lichtmaier in
3985 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
3987 2004-01-14 Paul Eggert <eggert@twinsun.com>
3989 * doc/autoconf.texi (Programming in M4sh): Document that
3990 AS_MKDIR_P succeeds if the destination is a symbolic link
3991 to an existing directory.
3992 (Limitations of Usual Tools): Note that mkdir -p might not
3993 succeed on symlinks to directories.
3995 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
3997 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
3998 * bin/autoheader.in: Grammar fix in message.
3999 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4000 Test for dir before calling mkdir -p. (trivial changes)
4002 2004-01-13 Eric Blake <ebb9@byu.net>
4004 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4005 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4007 2004-01-10 Jim Meyering <jim@meyering.net>
4009 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4011 2004-01-09 Paul Eggert <eggert@twinsun.com>
4013 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4014 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4015 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4016 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4017 AC_COMPILE_IFELSE, since we now assume our caller invokes
4018 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4019 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4020 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4021 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4023 2004-01-07 Paul Eggert <eggert@twinsun.com>
4025 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4026 `"'...'"`, as it's confusing (and I suspect it may not work on
4027 some platforms). The code was incorrect anyway, as it assumed
4028 that \$ evaluated to itself in that context. Reported by
4029 Alexandre Duret-Lutz.
4031 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4033 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4034 and _LT_AC_TAGCONFIG.
4036 2004-01-06 Paul Eggert <eggert@twinsun.com>
4038 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4039 example, and add more examples. Reported by Eric Sunshine.
4041 2004-01-05 Paul Eggert <eggert@twinsun.com>
4043 * doc/autoconf.texi (Limitations of Usual Tools):
4044 Remove warning against "rm -fr" introduced yesterday; it
4045 was a false alarm.
4047 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4048 autoscan, autoupdate, ifnames): Don't use chmod -w.
4049 * lib/Makefile.am (autom4te.cfg): Likewise.
4050 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4051 "chmod -w".

4054 Paolo Bonzini <bonzini@gnu.org>
4056 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4057 by doing lineno substitution only on lines containing "$LINENO".
4059 2004-01-04 Paul Eggert <eggert@twinsun.com>
4061 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4062 Use "rm -f" to remove conftest.sed, not plain "rm".
4063 Bug reported by David Relson in
4064 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4066 * Makefile.am (autom4te-update):
4067 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4068 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4069 * doc/autoconf.texi (Guidelines): Likewise.

4077 srcdir): Likewise.
4078 * doc/autoconf.texi (Limitations of Usual Tools):
4079 Warn against "rm -fr".
4081 2004-01-03 Paul Eggert <eggert@twinsun.com>
4083 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4084 -c -o might not work. From a suggestion by Kevin Ryde.
4085 (C Compiler, Generating Sources, Limitations
4086 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4087 Don't put '-o' after non-options, as POSIX doesn't allow this.

4155 * config/announce-gen (&print_locations, &print_signatures)
4156 (&sizes): New.
4157 Use them.
4158 No longer rely on Gnus to inline the list of signatures: compute
4159 them on the fly.
4161 2003-11-24 Akim Demaille <akim@epita.fr>
4163 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
4164 override some files.
4165 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
4166 From Debian Autoconf 2.58.

4206 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4207 than $target since the latter is not usual, add guidelines on when to

4212 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

4232 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

4367 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
4368 cross test.
4370 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
4372 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
4373 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

4385 Problems reported by Eric Sunshine.
4387 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4389 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4390 -mGLOB_options_string stuff for Intel ifc, which can cause

4412 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
4414 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4415 cache variable instead of $G77 to decide whether to include -O2,
4416 since $G77 is specific to Fortran 77.
4418 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4420 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

4423 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4425 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4426 arguments so that it can be used with syntax identical to
4427 AC_PROG_F77, and so that we can more easily decide to
4428 remove/deprecate the DIALECT optional argument in the future if it
4429 proves troublesome.
4430 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4431 non-freeform-supporting compilers. Document freeform flags.
4433 2003-10-03 Akim Demaille <akim@epita.fr>
4435 * configure.ac: Look for emacs, not macs.
4436 Reported by Eric Sunshine.
4438 2003-10-03 Akim Demaille <akim@epita.fr>
4440 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
4441 * bin/autoreconf.in (autoreconf_current_directory): Create the

4443 Suggested by Alexandre Duret-Lutz.
4445 2003-10-03 Akim Demaille <akim@epita.fr>
4447 * configure.ac: Quotation and formatting changes.

4469 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
4470 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

4477 (@news_file): this.
4479 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

4482 have been created when invoking the compiler.

4496 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4497 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4498 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4500 2003-09-26 Akim Demaille <akim@epita.fr>
4502 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4503 directory for AC_CONFIG_COMMANDS' first argument exists.
4504 This makes valid the invocation of _AC_SRCPATH that follows.
4505 Reported by Eric Sunshine.
4506 * doc/autoconf.texi (Configuration Commands): Adjust.
4508 2003-09-26 Akim Demaille <akim@epita.fr>
4510 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4511 Reported by Ralf Corsepius.
4513 2003-09-26 Akim Demaille <akim@epita.fr>
4515 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4516 arguments.

4527 2003-09-26 Akim Demaille <akim@epita.fr>
4529 The test suite are sometimes assigning timings incorrectly.
4530 Reported by Henk Krus.
4531 Diagnosed by Nicolas Joly.
4533 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4534 AT_help_all.
4535 Instead of making AT_help a sequence of assignments to grow
4536 $at_help_all, just make AT_help_all be the growing contents of
4537 $at_help_all, and make a single assignment in...
4538 (AT_INIT): here.
4539 (at_times_skip): Flip the meaning and rename as...
4540 (at_times_p): this.
4541 (AT_INIT): When summarizing the test that ran, remove
4542 $at_times_file after use, and check it is present before trying to
4543 use it.

4551 (ifnames): chmod -w.
4552 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4553 executables, not bin/ executables! Otherwise all the magic needed
4554 to find non installed files is turned off. This caused a failure
4555 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4556 as found in its environment (sent by tests/autoreconf): pointing
4557 to bin/autom4te that could not find its files.
4558 * tests/mktests.sh: Force the replacement of generated files, for
4559 the sake of "mv" program that are interactive when overwriting a
4560 -w file.
4561 * config/install-sh: Upgrade from CVS Automake.

4571 Trivial change to support GCC's configuration procedure.
4572 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4573 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4574 about inconsistency if the preprocessor is set to give errors for
4575 any warning.
4576 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4578 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

4657 unchanged, and continues to support Fortran 77. New FC macros
4658 correspond to all the old F77 macros, with output variables FC,
4659 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4660 available dialect, but older dialects can be specified. There are
4661 new macros AC_FC_SRCEXT to set the source extension, and
4662 AC_FC_FREEFORM to accept free-form source files.
4664 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4665 New macros.

4700 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4701 are defaulted by AT_CHECK anyway.
4702 Use AT_CHECK_AUTOM4TE.
4703 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4704 missing dnl.
4706 2003-08-27 Akim Demaille <akim@epita.fr>
4708 * bin/autoheader.in: Issue the "Using auxiliary..." message only

4755 2003-08-22 Akim Demaille <akim@epita.fr>
4757 Output stack traces in warnings.
4759 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.

4761 (m4_warn): Pass the call stack to _m4_warn.
4762 * bin/autom4te.in: Adjust to output the call stack.
4763 * tests/m4sugar.at (m4@&t@_warn): Adjust.
4765 2003-08-22 Akim Demaille <akim@epita.fr>
4767 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
4768 * bin/autom4te.in: Adjust.
4770 2003-08-21 Akim Demaille <akim@epita.fr>
4772 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
4773 (&verbose): Remove.
4774 (&getopt): Adjust the note and verb channels, depending upon
4775 --verbose.
4776 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
4777 * bin/autoupdate.in: Adjust.
4778 Use &verb, not &verbose.
4780 2003-08-21 Akim Demaille <akim@epita.fr>
4782 * bin/autoheader.in (&parse_args): Use &parse_warnings and
4783 &parse_WARNINGS.

4785 * bin/autoscan.in: Use Autom4te::ChannelDefs.
4786 * lib/Autom4te/General.pm: Don't export error: you don't own it.
4788 2003-08-21 Akim Demaille <akim@epita.fr>
4790 First stab at preserving warnings between calls to autom4te,
4791 including when the cache is used.
4793 There are still several issues: (i) there are too many runs of m4
4794 (one for include, one for warnings, and some more), (ii) warnings
4795 spreading on several lines are not handled gracefully, (iii) the
4796 code meant to have the call stack display for errors does not work
4797 (its handling should move from m4 to autom4te).
4799 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4800 Use them.
4801 (@preselect): Add m4_warn.
4802 ($exit_status): Remove, use $exit_code.
4803 ($help): Use Autom4te::ChannelDefs::usage.
4804 (&handle_m4): No longer define the m4_warnings.
4805 At each run, extract and report the warnings.
4806 Always cache the result, including if the exit status is on
4807 failure, since if nothing changes, we should result in the same
4808 failure, hence we can use the cache.
4809 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4810 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4811 Remove.
4812 (m4_warn): Redefine as a do-nothing: it is its invocation that
4813 matters, as warnings are now reported via traces.
4814 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4815 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4816 the latter reveals calls to the former.
4818 Adjust the tests.
4820 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4822 2003-08-21 Akim Demaille <akim@epita.fr>
4824 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
4825 Use them.
4827 2003-08-21 Akim Demaille <akim@epita.fr>
4829 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4830 forward order.
4831 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4832 (&parse_warnings): Accept a list of warning requests.
4833 (&usage): Return a string, not a side effect.
4834 (cross): New warning category.
4836 2003-08-21 Akim Demaille <akim@epita.fr>
4838 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4839 (&require_configure_ac): Accept an optional directory argument.
4840 ($configure_ac): Remove.
4841 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4842 (&catfile): Remove.
4843 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4844 * bin/autoscan.in: Adjust.
4846 2003-08-20 Akim Demaille <akim@epita.fr>
4848 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4849 Reported by Alexandre Duret-Lutz.
4851 2003-08-20 Akim Demaille <akim@epita.fr>
4853 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4854 * bin/autom4te: Adjust.
4855 In particular, be Autoconf tools are really silent when properly
4856 working, bind the verbosity of the 'note' channel to $verbose.
4857 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4858 (&xsystem, &contents): Remove, since they are exported by...
4859 * lib/Autom4te/FileUtils.pm: this.
4860 More perldoc.
4861 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4862 * lib/Autom4te/FileUtils.pm: here.
4864 2003-08-20 Akim Demaille <akim@epita.fr>
4866 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
4867 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

4878 * lib/autotest/general.m4: Comment various HELP_* diversions.
4879 (PARSE_ARGS_BEGIN): New section for option parsing related

4890 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4892 * lib/autom4te.in (Automake-preselections): Preselect
4893 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
4894 and m4_sinclude.
4896 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4898 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

4919 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4920 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4921 shorter column three. Add DESCRIPTION to log file content.
4923 2003-08-13 Derek Price <derek@ximbiot.com>
4925 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
4926 output.

4937 (AT_CHECK_NOESCAPE): ...to this new macro.
4939 2003-07-31 Paul Eggert <eggert@twinsun.com>
4941 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
4942 in Bash 2.01. Problem reported by Brian Gough in
4943 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
4945 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>

4952 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
4953 inside '#ifndef __cplusplus'. Problem reported by
4954 Bob Friesenhahn.
4956 2003-07-06 Bill Clarke <llib@computer.org>
4958 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
4959 'long', not 'int', for benefit of Sun's recent C++ compilers
4960 (trivial change). See:
4961 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
4962 (This really should be 'intptr_t', not 'long', but that would
4963 take more work.)
4965 2003-06-25 Akim Demaille <akim@epita.fr>
4967 * lib/Makefile.am (autom4te.cfg): Make it read only.
4968 Depend on Makefile since it contains substitutions.

4977 From Gareth McCaughan.
4979 2003-06-23 Akim Demaille <akim@epita.fr>
4981 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
4982 not all of them. This fixes 1. the fact that when testing
4983 Autoconf there are many many config.log, 2. the incorrect use of
4984 top_srcdir to find config.log.
4985 Don't mix the detailed output of failed test with the summary of
4986 failures. Rather, append detailed log afterwards.
4988 2003-06-23 Akim Demaille <akim@epita.fr>
4990 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
4991 always run: output config.log on $at_group_log.

5066 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5068 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5069 (handle_exec_errors): New function. Work around $! being
5070 altered by WEXITSTATUS.
5071 (xqx, xsystem): Use handle_exec_errors.
5073 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5075 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5076 Do not call `_exit()', simply modify `$?'.
5077 (xsystem): Reset $! before running system, and check it afterward.
5078 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5079 63 for version mismatches.
5081 2003-05-23 Akim Demaille <akim@epita.fr>
5083 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5084 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5085 the middle of a line).
5086 * lib/m4sugar/m4sugar.m4: Likewise.
5087 Remove useless spaces in comments.
5089 2003-05-23 Akim Demaille <akim@epita.fr>
5091 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5092 exit 63, so that we (or Automake's "missing") can tell the
5093 difference with a plain failure.
5094 * doc/autoconf.texi (Notices): Adjust.
5096 2003-05-23 Akim Demaille <akim@epita.fr>
5098 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5099 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5100 White spaces cleanup.
5102 2003-05-22 Jim Meyering <jim@meyering.net>
5103 Paul Eggert <eggert@twinsun.com>
5105 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5106 Remove `#include <stdlib.h>' from the list; we should never
5107 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5108 resulting namespace pollution would cause other tests to fail.
5109 Configure scripts run with some older versions of g++ and HP's
5110 aCC would fail due to such an #include. Problems reported by
5111 Matthew Mueller in <http://bugs.debian.org/120704> and by
5112 Keith Bostic in
5113 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5114 In the test, use the test declaration before including <stdlib.h>,
5115 as that's closer to how it'll be used.
5117 2003-05-23 Akim Demaille <akim@epita.fr>
5119 * doc/autoconf.texi (Header Portability): ucred.h.
5120 From Ian Redfern.
5122 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5124 Overhaul Autotest's logging: generate separate log files
5125 in testsuite.dir/NNN/testsuite.log, and append them to
5126 testsuite.log instead of re-running the test verbosely.
5128 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5129 file descriptor, write 0 to at_status_file instead of setting
5130 at_status=0, initialize some new variables (at_status_file,
5131 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5132 to rerun the tests, instead append the at_group_log to the
5133 at_suite_log when a test fails.
5134 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5135 with the AS_MESSAGE_LOG_FD redirected to stdout.
5136 (AT_CLEANUP): save the output status in $at_status_file
5137 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5138 its original place.
5139 (AT_CHECK): since tests are run with a redirected stdout,
5140 and used to be re-run in verbose mode, turn some $at_verbose
5141 into echo, and don't redirect the output of testing stdout
5142 and stderr.
5144 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5145 the name of the debugging directory and information about
5146 its contents.
5148 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5150 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5151 parameter.

5173 Whitespace clean up.
5174 Suggested by Jim Meyering.

5219 * lib/autoconf/functions.m4: Use the default includes so that
5220 memcmp be declared before being tested.
5221 Reported by Sander Niemeijer.
5222 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
5223 * doc/autoconf.texi (Default Includes): Document
5224 AC_INCLUDES_DEFAULT.
5226 2003-05-17 Akim Demaille <akim@epita.fr>

5236 Reported by Bruno Haible.
5238 2003-05-16 Akim Demaille <akim@epita.fr>

5263 and truncate.
5265 2003-05-06 Akim Demaille <akim@epita.fr>
5267 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5268 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5269 by aclocal.m4 is changed it might require the importing of another
5270 m4 extension file, i.e., aclocal must be run.
5272 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5273 (&parse_args): Use --force with aclocal if required and supported.
5274 (&autoreconf_current_directory): Use &run_aclocal.

5281 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5282 argument instead of a file name, so that the request file remains
5283 open during the whole autom4te run.
5284 ($icache_file): New.
5285 (&freeze): Lock the $icache_file.
5287 2003-04-29 Derek Price <derek@ximbiot.com>
5289 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5290 seperator with m4_append_uniq(). It doesn't work.
5291 (AT_CLEANUP): Add `;' to end of at_help_all.
5292 (AT_INIT): Allow --keywords to be specified more than once. When
5293 grepping $at_help_all for keywords, use the field and keyword
5294 seperators to ensure a complete keyword match. Alter at_prev handling
5295 to support the new --keywords behavior.
5297 2003-04-27 Karl Berry <karl@freefriends.org>
5299 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5300 align better with others. I also made some of the individual
5301 entries on one line, for brevity and to make it easier for me to
5302 sort my dir-example file in the Texinfo distribution :).
5304 2003-04-12 Jim Meyering <jim@meyering.net>
5306 * NEWS: Mention the new macro.

5347 2003-03-31 Derek Price <derek@ximbiot.com>
5349 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
5350 which removed the main loop.
5351 Thanks to Akim Demaille.
5353 2003-03-29 Akim Demaille <akim@epita.fr>

5356 that starts a GUI.
5357 From Ilya Zakharevich.
5359 2003-03-29 Akim Demaille <akim@epita.fr>

5363 Suggested by Paul Eggert.
5365 2003-03-28 Akim Demaille <akim@epita.fr>
5367 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
5368 reading the section "Present But Cannot Be Compiled" when the
5369 header causes problems.
5371 2003-03-28 Akim Demaille <akim@epita.fr>
5373 * tests/torture.at (Configuring subdirectories): Require aclocal
5374 1.4, otherwise the test fails, as it does support configure.ac.
5375 This fixes the "test 40 failed" bug reports.
5377 2003-03-28 Akim Demaille <akim@epita.fr>
5379 * doc/autoconf.texi (C Compiler): `#line' portability.
5380 From Paul Eggert and Nelson H. F. Beebe.
5382 2003-03-27 Derek Price <derek@ximbiot.com>
5384 * lib/autotest/general.m4: Eliminate main loop and reorganize test
5385 layout in order to allow scripting around test groups.

5446 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5447 Tru64 make in the "target lookup" section.
5448 (Automake): Automake 1.5+ no longer requires special tools to be
5449 present on the developer's host.

5467 ${ac_make}.
5469 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5470 When constructing paths with IFS=:, quote the path. If we're

5490 to fix a mismatch between example and discussion.
5492 2003-02-24 Kevin Ryde <user42@zip.com.au>
5494 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5495 format starting with "-".
5497 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5499 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5500 is not portable inside Makefile.
5502 2003-02-20 Akim Demaille <akim@epita.fr>
5504 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5505 compiler says yeah, but preproc says nope, compiler is right.
5506 Conversely, prompt the reader to send a bug report to the
5507 maintainers of the package, not of Autoconf.
5509 2003-02-20 Klee Dienes <kdienes@apple.com>
5511 * bin/autoreconf.in (autoreconf_current_directory): Properly

5522 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5523 innocuous variant befor including <limits.h> or <assert.h>. This
5524 works around a bug reported by Albert Chin: HP-UX 11i
5525 (and earlier versions) have a <limits.h> that declares
5526 gettimeofday and many other functions.
5528 2002-12-03 Paul Eggert <eggert@twinsun.com>
5530 Version 2.57.
5532 * NEWS, configure.ac: Update version.

5536 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5537 nontrivially in main's body, so that f's external declaration is
5538 not optimized away in AIX. This should fix the bug reported by
5539 Martin Frydl in
5540 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5542 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5543 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5544 defined, to support freestanding compilers. This should fix the
5545 bug reported by Momchil Velkov in
5546 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.

5580 Update from masters.
5582 2002-11-14 Akim Demaille <akim@epita.fr>
5584 * Makefile.maint: Sync with Bison, i.e.:
5585 (po-check): Scan .l and .y files instead of the
5586 .c and the .h files that they generate. This fixes the bug
5587 reported by Tim Van Holder in:
5588 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5589 Look for N_ as well as for _. Try to avoid matching #define for
5590 N_ and _.

5605 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5606 than assigning in main, to avoid HP cc +O3 optimizing it away.

5610 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5611 option. Process --recheck after parsing all options. Pass -q
5612 option to configure on --recheck.

5644 Reported by Ezra Peisach.
5646 2002-11-05 Akim Demaille <akim@epita.fr>
5648 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5649 Remove.
5650 We _have_ to stop using the old compatibility scheme that tried to
5651 avoid useless backslashes because Libtool 1.4.3 contains a
5652 AC_DEFINE([error_t], [int],
5653 [Define to a type to use for \`error_t' if it is not
5654 otherwise available.])
5655 We _have_ to quote the single quote and backslashes with \. The
5656 old compatibility scheme saw that ` was backslashed, and therefore
5657 did not quote the single quote. Hence before this patch, Autoconf
5658 was not compatible with Libtool.

5702 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5703 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5704 Make variable, not a shell variable.
5705 Suggested by Bruno Haible.
5707 2002-10-31 Akim Demaille <akim@epita.fr>
5709 * bin/autom4te.in (load_configuration): Reject #args out of any
5710 language.

5726 Suggested by Tim van Holder.

5731 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5732 Problem reported by Bruno Haible.
5734 2002-10-29 Akim Demaille <akim@epita.fr>
5736 * doc/autoconf.texi (Header Templates): Put also in words what the
5737 pictures says to assist free style readers.
5738 (Customizing autom4te): s/--cache=/--cache /.
5740 2002-10-29 Akim Demaille <akim@epita.fr>

6047 Because of caching, some files that no longer exist and are no
6048 longer required can still cause errors.
6049 Reported by Alexandre Duret-Lutz.
6051 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6052 to frozen files in @ARGV, as @ARGV must remain being a list of
6053 files. Rather, at M4 call sites, use this...
6054 (&files_to_options): New function.
6055 (&freeze): Use &error.
6056 (&up_to_date): If a file that was included according to the cache
6057 is no longer there, then the output is out dated.
6058 (&main): Don't even check whether a file is up to date is anyway
6059 --force is given.
6060 * tests/tools.at (autom4te cache): New.
6062 2002-10-16 Akim Demaille <akim@epita.fr>
6064 * bin/autoconf.as: Kill dead options.
6065 * bin/autoupdate.in (&parse_args): Kill old options.
6066 * bin/autoreconf.in (&parse_args): Remove dead options.
6067 Factor some code.
6068 (&autoreconf): Report the directories we enter *and leave*, so
6069 that error messages can be easily located, and use GNU Make
6070 format, so that Emacs' compile mode understands us.
6071 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6072 if some file was changed instead of `print'.
6073 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6074 (&parse_args): Remove the dead options.
6075 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
6076 autoheader's quiet mode.
6077 (AT_CHECK_AUTOUPDATE): Likewise.
6078 * tests/tools.at (autoupdate): Adjust.
6079 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6081 2002-10-11 Akim Demaille <akim@epita.fr>
6083 No longer use CPP to check for the existing of headers: use CC to
6084 check for compilability.
6086 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6087 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
6088 (_AC_CHECK_HEADER_NEW): Rename as...
6089 (AC_CHECK_HEADER): this.
6091 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6092 numbers in the Subject suggestion.
6094 2002-10-11 Akim Demaille <akim@epita.fr>
6096 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
6097 Suggest using AC_CHECK_DECLS instead.
6099 2002-10-11 Akim Demaille <akim@epita.fr>
6101 * tests/torture.at (AC_ARG_VAR): Have configure report the value
6102 of `precious'.
6104 2002-10-11 Akim Demaille <akim@epita.fr>
6106 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6107 file name to enable parallel executions.
6108 From Sam Varshavchik.
6110 2002-10-08 Akim Demaille <akim@epita.fr>
6112 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6113 aclocal invocation, as Gettext macros might not be visible to
6114 aclocal.
6115 Instead of blindly running autopoint, scan configure.ac (not the
6116 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6117 Reported by Paul D. Smith.
6119 2002-10-08 Paul Eggert <eggert@twinsun.com>
6121 Work around problems found when POSIXLY_CORRECT=1 is set.
6122 None of this seems to have anything to do with POSIX, really,
6123 but it's how Perl getopt works.
6124 * bin/autom4te.in (parse_args): Configure GetOpt with
6125 "permute", too.
6126 * doc/autoconf.texi (Invoking autom4te):
6127 --warning -> --warnings.
6128 * lib/autom4te.in: --warning -> --warnings.
6130 2002-09-28 Akim Demaille <akim@epita.fr>
6132 * doc/autoconf.texi (autom4te.cache): New section.
6134 2002-09-28 Akim Demaille <akim@epita.fr>
6136 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
6137 (Automake-preselections): Update.
6138 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
6140 2002-09-28 Akim Demaille <akim@epita.fr>
6142 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
6143 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
6144 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
6145 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
6147 2002-09-28 Akim Demaille <akim@epita.fr>
6149 * tests/torture.at (Configuring subdirectories): Be robust to
6150 users who use config.site to require for a cache: in this case,
6151 the two last configure runs, using two different sets of
6152 arguments, trigger a legitimate error.
6154 2002-09-28 Akim Demaille <akim@epita.fr>
6156 * tests/m4sh.at (Functions Support, Functions and return Support):
6157 New.
6159 2002-09-28 Akim Demaille <akim@epita.fr>
6161 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
6162 autoheader are Perl programs.
6163 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
6164 (autom4te): Specify that the sources are in the $srcdir.
6165 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6167 2002-09-28 Akim Demaille <akim@epita.fr>
6169 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
6170 (tm_zone): Move their rules to...
6171 * lib/autoconf/types.m4: here, using AN_ macros.
6172 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6173 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6174 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6175 * lib/autoconf/programs.m4: here.
6176 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
6177 (ETAGS_FOR_AUTOCONF): New.
6178 Use it.
6180 2002-09-28 Akim Demaille <akim@epita.fr>
6182 * lib/autoconf/autoscan.m4: New file.
6183 * lib/autoconf/autoconf.m4: Include it.
6184 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
6185 that were listed in the original autoscan.list.
6186 * lib/autoconf/headers.m4: Similarly with headers.
6187 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6188 (.m4.m4f): Don't pass --prepend-include, since that's done by
6189 tests/autom4te itself.
6190 * lib/autoscan/Makefile.am: Include freeze.mk.
6191 (autoscan.list): New target --this file is no longer a source.
6192 (autoscan.pre): New file.
6194 2002-09-28 Akim Demaille <akim@epita.fr>
6196 * bin/autoscan.in (@kinds): Make them singular.
6197 Adjust all uses.
6198 (&init_tables): When --debug, report the list of rules to ease
6199 tracking changes in autoscan.list.
6200 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6202 2002-09-28 Akim Demaille <akim@epita.fr>
6204 * lib/autoscan/functions, lib/autoscan/headers,
6205 * lib/autoscan/identifiers, lib/autoscan/makevars,
6206 * lib/autoscan/programs: Merge into...
6207 * lib/autoscan/autoscan.list: this.
6208 * bin/autoscan.in (&init_tables): Adjust.
6210 2002-09-28 Akim Demaille <akim@epita.fr>
6212 * lib/autoscan/functions, lib/autoscan/headers,
6213 * lib/autoscan/identifiers, lib/autoscan/makevars,
6214 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6215 `functions' line is now prefixed with `function:'.
6216 * bin/autoscan.in (&init_tables): Adjust.
6218 2002-09-28 Akim Demaille <akim@epita.fr>
6220 From now on, autoscan files must always map a macro name to a
6221 word: there is no `default' macro for autoscan.
6223 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6224 all.
6225 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6226 explicit.
6228 2002-09-28 Akim Demaille <akim@epita.fr>
6230 * bin/autoscan.in (%c_keywords): Remove.
6231 (&used): Keep only track of the words we might be interested in.
6232 (&output_kind): It is no longer needed to look for non active
6233 checks.
6235 2002-09-27 Akim Demaille <akim@epita.fr>
6237 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
6238 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
6239 * lib/autoscan/functions: Adjust.
6240 * doc/autoconf.texi (Particular Functions): Adjust.
6242 2002-09-27 Akim Demaille <akim@epita.fr>
6244 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
6245 from /tmp.
6246 Thanks to Bill Moseley and Paul Eggert.
6247 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6248 the tmpdir must be created.
6249 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6250 dir be in the build tree, instead of $TMPDIR.
6252 2002-09-27 Akim Demaille <akim@epita.fr>
6254 * bin/autoscan.in: Improve the comments.
6255 (&parse_args): Drop obsolete undocumented options.
6256 (&output_kind): Output warnings.
6257 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
6258 (getwd): Trigger a warning.
6260 2002-09-26 Akim Demaille <akim@epita.fr>
6262 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6263 Reported by Ralf Corsepius.
6264 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6266 2002-09-26 Akim Demaille <akim@epita.fr>
6268 Single suffix rules and seperated dependencies are not portable.
6270 * doc/autoconf.texi (Installation Directory Variables): Update.
6271 (Limitations of Make): Some about `Single Suffix Rules and
6272 Separated Dependencies'.
6273 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6274 (ifnames, autoscan, autom4te): Un-factor into several rules.
6276 2002-09-25 Paul Eggert <eggert@twinsun.com>
6278 * BUGS (Interoperability bugs): New section. Mention libtool
6279 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6281 2002-09-24 Paul Eggert <eggert@twinsun.com>
6283 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6284 make handles suffix-rules differently from GNU make.
6286 * bin/Makefile.am (SUFFIXES, .in): Remove.
6287 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6288 Move the body of the old .in rule here.
6290 2002-09-16 Akim Demaille <akim@epita.fr>
6292 i960 compilers create `b.out' files by default.
6293 Reported by Ralf Corsepius.
6295 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6296 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6298 2002-09-13 Paul Eggert <eggert@twinsun.com>
6300 * doc/autoconf.texi (Particular Headers): Remove obsolete
6301 reference to `struct timezone' in the description of
6302 AC_HEADER_TIME.
6304 2002-09-13 Akim Demaille <akim@epita.fr>
6306 Version 2.54.
6308 * config/config.sub, config/config.guess: Update.
6309 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6310 * Makefile.am: Adjust.
6312 2002-09-13 Akim Demaille <akim@epita.fr>
6314 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6315 reading config.log when the compiler is rejected.
6316 Suggested by Guido Draheim.
6318 2002-09-13 Akim Demaille <akim@epita.fr>
6320 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6321 (chdir_init) might hang when stat'ing mounted directories.
6322 Reported by Vance Shipley.
6324 2002-09-12 Akim Demaille <akim@epita.fr>
6326 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6327 the lists.
6329 2002-09-12 Akim Demaille <akim@epita.fr>
6331 * doc/autoconf.texi (Defining Symbols): Present two different
6332 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6333 difference between 1 argument calls, and 2-3 argument calls.
6335 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6337 * doc/autoconf.texi: Review grammar and punctuation.
6339 2002-09-11 Paul Eggert <eggert@twinsun.com>
6341 * doc/autoconf.texi: Fix minor formatting, spelling, and
6342 grammatical typos.
6343 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6344 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6345 is obsolescent.
6347 2002-09-11 Akim Demaille <akim@epita.fr>
6349 * doc/autoconf.texi (Questions): Rename as...
6350 (FAQ): this.
6351 (Defining Directories): New.
6353 2002-09-09 Akim Demaille <akim@epita.fr>
6355 * doc/autoconf.texi (Making testsuite Scripts): Update.
6356 Suggested by Nishio Futoshi.
6358 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6360 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6361 plain `@' is wanted.
6363 2002-09-09 Akim Demaille <akim@epita.fr>
6365 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6366 `duplicates', since the algorithm was too naive and could keep
6367 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6368 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6369 Reported by Ralf Corsepius.
6370 * tests/torture.at (Configuring subdirectories): Exercise these
6371 cases.
6373 2002-09-09 Akim Demaille <akim@epita.fr>
6375 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6376 looking for a replacement file.
6377 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6378 directory is relative.
6379 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6380 directory definition.
6381 Reported by Andreas Schwab and Jim Meyering.
6383 2002-09-06 Akim Demaille <akim@epita.fr>
6385 * doc/autoconf.texi (Setting Output Variables): Clarify what
6386 precious variables are.
6387 Suggested by Pontus Skoeld.
6389 2002-09-05 Akim Demaille <akim@epita.fr>
6391 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6392 (ifnames, autoscan, autom4te): Since we don't only depend on
6393 configure.ac variables (such as VERSION etc.), but also on prefix
6394 and so forth, depend on Makefile, not configure.ac.
6395 Reported by Alexandre Duret-Lutz.
6396 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6398 2002-09-05 Kevin Ryde <user42@zip.com.au>
6400 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6401 doesn't seem to be confined to ia64, just say "some versions".
6403 2002-09-04 Akim Demaille <akim@epita.fr>
6405 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6406 Automake 1.6c.
6407 * Makefile.am (maintainer-clean-local): Remove.
6408 (MAINTAINERCLEANFILES): Remove COPYING.
6410 2002-09-03 Paul Eggert <eggert@twinsun.com>
6412 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6413 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6414 Brinkmann.
6416 2002-09-03 Akim Demaille <akim@epita.fr>
6418 * configure.ac: Bump to 2.53d.
6419 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6420 as of today, on Automake's team suggestion.
6422 2002-09-03 Akim Demaille <akim@epita.fr>
6424 Version 2.53c.
6426 2002-09-02 Akim Demaille <akim@epita.fr>
6428 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6429 SITE_MACRO_DIR.
6430 * configure.ac: Disable SITE_MACRO_DIR.
6432 2002-09-02 Jim Meyering <meyering@lucent.com>
6434 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6435 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6436 Also, tweak grammar: s/make sure to/be sure to/.
6438 2002-09-02 Paul Eggert <eggert@twinsun.com>
6440 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6441 directory names are generally preferable to physical names.
6443 2002-09-02 Akim Demaille <akim@epita.fr>
6445 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6446 Reported by Raja R. Harinath.
6447 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6448 * bin/autoupdate.in: Use error instead of die.
6450 2002-09-01 Paul Eggert <eggert@twinsun.com>
6452 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6453 ordinary shell concatenation rather than echo+tr+sed command that
6454 runs afoul of a long-line-related sed bug in Solaris 8.
6456 * bin/autoheader.in (parse_args): --warning -> --warnings.
6458 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6459 stdout, as traditional "ls" does.
6460 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6461 _AC_COMPILER_EXEEXT_O): Likewise.
6462 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6464 * bin/autoconf.as: Add --prepend-include option. This patch was
6465 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6466 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6468 * bin/autoconf.in, configure: Regenerate.
6470 * doc/autoconf.texi (Special Shell Variables): Mention
6471 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6473 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6474 MAILPATH and set PS1, PS2, PS4 to default values, to work
6475 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6476 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6477 the Autoconf documentation specifies; fall back to "unset" only if
6478 this fails. Use a shell for-loop for this rather than an m4 loop,
6479 to shorten the output script.
6481 2002-08-30 Paul Eggert <eggert@twinsun.com>
6483 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6484 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6485 for the CDPATH problem. Document PWD.
6486 (Limitations of Builtins): Document the problem that "cd $foo" and
6487 "ls $foo" may refer to different directories in shells conforming
6488 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6489 example, since the old example is now out of date.
6491 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6492 FOO" and "ls FOO" talk about different directories; this catches
6493 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6494 spaghetti.
6496 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6497 of rolling our own unset.
6498 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6499 in practice we needn't worry about CDPATH if unset doesn't work.
6501 * Makefile.in, aclocal.m4, bin/Makefile.in,
6502 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6503 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6504 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6505 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6506 tests/Makefile.in: Regenerate with Automake 1.6.3.
6508 * config/config.guess, config/config.sub, config/mkinstalldirs:
6509 Update.
6511 * configure: Regenerate with self.
6513 2002-08-30 Kevin Ryde <user42@zip.com.au>
6515 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6516 default output.
6518 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6520 * bin/autom4te.in (Request::load): Correctly test for "do" read
6521 failure.
6523 2002-08-29 Akim Demaille <akim@epita.fr>
6525 * lib/Autom4te/General.pm (&xqx): New.
6526 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6527 hand, which is not portable.
6528 (&error): New.
6529 * bin/autom4te.in: Use them.
6530 Use &error instead of die.
6531 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6532 Adjust.
6534 2002-08-17 Paul Eggert <eggert@twinsun.com>
6536 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6537 default list of compilers to try, since it was long ago superseded
6538 by the ksh fc builtin. Suggested by Steven G. Johnson.
6540 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6542 * doc/autoconf.texi (Invoking autom4te): End the option table,
6543 fixing a bug introduced by the previous patch.

6563 (AM_MAKEINFOFLAGS): New macro.
6564 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6565 * Makefile.am (INSTALL): Use the new macros.
6566 Use -o rather than --output, since "missing" does not grok --output.
6568 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6570 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

6576 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):

6708 so that Emacs setups GNU style for perl-mode and cperl-mode.
6710 2002-06-27 Paul Eggert <eggert@twinsun.com>
6712 * config/install-sh: Quote $src. Prefer || to test's -o option,
6713 as per "Limitations of Builtins".
6714 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
6715 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6717 * tests/mktests.sh: Use grep instead of fgrep, as per
6718 "Limitations of Builtins".
6720 2002-06-15 Paul Eggert <eggert@twinsun.com>
6722 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

6724 so that we consistently test the just-built programs.

6739 on Solaris 2.5.1.
6741 2002-06-11 Andreas Schwab <schwab@suse.de>

6745 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
6747 * bin/autom4te.in ($cache): Don't define using `$me', the name
6748 of the cache should not depend on the name under which autom4te
6749 was installed.
6751 2002-06-07 Akim Demaille <akim@epita.fr>
6753 * tests/tools.at (autoconf: forbidden tokens, basic)

6775 2002-06-07 Akim Demaille <akim@epita.fr>
6777 * bin/autom4te.in (warn_forbidden): When rejecting a token,

6779 Suggested by Adam J. Richter.
6781 2002-06-07 Akim Demaille <akim@epita.fr>

6784 ac_config_libobj_dir.
6785 (AC_CONFIG_LIBOBJ_DIR): New.
6786 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

6799 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
6800 if ln doesn't work.
6801 * NEWS: Likewise.
6802 * doc/autoconf.texi (Configuration Links): Likewise.

6842 2002-05-22 Paul Eggert <eggert@twinsun.com>
6844 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77

6853 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6854 This improves on an earlier suggestion by H. Peter Anvin.
6856 2002-05-16 Paul Eggert <eggert@twinsun.com>
6858 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6859 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6860 Both macros now accept an optional source-dir arg.
6861 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6863 * NEWS: Document this.
6864 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6866 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6867 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6868 not for GNU extensions; this undoes part of the 2000-11-03 change,
6869 reverting to 2.13-compatible behavior.
6870 Add new optional argument DIR.
6871 (AC_FUNC_FNMATCH_GNU): New macro.
6873 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6875 2002-05-08 Paul Eggert <eggert@twinsun.com>
6877 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6878 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6879 and it causes a 'test' syntax error if it fails.
6880 Bug reported by Stephen Gildea.
6882 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6883 If prototypes are supported, use them to check this at compile-time,
6884 instead of trying to check it at run-time. If we must do a run-time
6885 check, assume that setvbuf is standard when cross-compiling, as
6886 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6887 Bug reported by Paul D. Smith.
6889 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6890 argument specifying location of getloadavg.c. This removes a
6891 FIXME. This idea was taken from Jim Meyering's implementation in
6892 textutils.
6893 * doc/autoconf.texi (Particular Functions): Document this.
6894 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6895 that's what the code does; this fixes a bug reported by
6896 Paul D. Smith.
6898 2002-05-03 Akim Demaille <akim@epita.fr>
6900 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6901 autopoint instead of gettextize.
6902 ($uses_alocal): Rename as...
6903 ($uses_aclocal): this.
6904 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6905 Suggested by Bruno Haible.
6907 2002-05-03 Akim Demaille <akim@epita.fr>
6909 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
6911 2002-04-29 Paul Eggert <eggert@twinsun.com>
6913 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
6914 files to be 1 second older; just set them to be the same time.
6915 Also, sleep 1 second after the first aclocal, to work around
6916 problems with sub-second time stamps on the input files.
6918 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6920 * doc/autoconf.texi: Mention "set -e -x" lossage
6921 under node "Limitations of Builtins".
6923 2002-04-29 Akim Demaille <akim@epita.fr>
6925 * doc/install.texi: Better wording for setting variables when
6926 running configure.
6927 From Christian Cornelssen.
6929 2002-04-29 Akim Demaille <akim@epita.fr>
6931 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
6932 of lack of $LINENO support, then the test will compare the $LINENO
6933 in testsuite vs. the lineno in the test file. This is wrong, of
6934 course.
6935 Be sure to protect it.
6936 Reported by Patrick Welche.
6938 2002-04-25 Akim Demaille <akim@epita.fr>
6940 * doc/autoconf.texi (Obsolete Macros): Typo.
6941 Reported by Vladimir Volovich.
6943 2002-04-25 Akim Demaille <akim@epita.fr>
6945 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
6946 than some of the input files, hence, on the second run of aclocal,
6947 if some of its input are younger, make them older.
6948 Suggested by Paul Eggert.
6950 2002-04-25 Akim Demaille <akim@epita.fr>
6952 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
6953 Thanks to Paul Eggert.
6955 2002-04-25 Akim Demaille <akim@epita.fr>
6957 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
6958 and ac_subst_vars be sh variables containing the list of
6959 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
6960 DEFAULT diversion.
6961 (_AC_INIT_PREPARE): Use them to log them.
6962 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
6963 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
6964 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
6965 _AC_SUBST_FILES and _AC_SUBST_VARS.
6966 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
6968 2002-04-24 Akim Demaille <akim@epita.fr>
6970 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
6971 autoheader, so that automake does not complain about a missing
6972 config.h.in that was to be created.
6974 2002-04-23 Akim Demaille <akim@epita.fr>
6976 * bin/autoheader.in (parse_args): --warning takes an argument.

7025 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
7026 Minor spelling and grammar fixes.
7028 * doc/autoconf.texi: Follow the outline suggested in the GNU
7029 Sample Texts sections of the Texinfo 4.2 manual. Most
7030 importantly, this makes sure that the copyright notices appear in
7031 all output formats. You probably need Texinfo 4.2 to generate
7032 the manual now.
7034 Fix some bugs when using "$@" when there might be zero positional
7035 arguments in cases where this matters.
7037 * bin/autoconf.as: Rewrite so that the problem does not come up.

7052 Use Zsh alias to work around problem.
7053 * tests/atgeneral.m4 (AT_INIT): Likewise.
7055 * tests/c.at: We can't have zero arguments, so remove workaround
7056 that is not portable to Zsh.
7058 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7060 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7061 from aclocal.m4 too.
7063 2002-04-12 Akim Demaille <akim@epita.fr>
7065 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7067 2002-04-10 Akim Demaille <akim@epita.fr>
7069 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7070 workaround for ${1+"$@"}.
7071 * doc/autoconf.texi (Shell Substitutions): Explain it.
7072 From Oliver Kiddle and Peter Stephenson.
7074 Have M4sh perform minimal shell sanitizing.
7076 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7077 part into...
7078 (_AS_PREPARE): this new macro.

7081 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7083 Adjust Autoconf and Autotest.
7085 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7086 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7087 * lib/autotest/general.m4 (AT_INIT): Likewise.
7088 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7089 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7090 AS_SHELL_SANITIZE.
7092 Use this M4sh to generate Autoconf's shell scripts.
7094 * tests/wrapsh.as: New, precursor of wrapsh.in.
7095 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7096 on Autotest and M4sh.
7097 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7098 (wrapsh.in): New target.
7099 * bin/autoconf.as: New, precursor of autoconf.in.
7100 (autoconf.in): New target.
7102 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7117 2002-04-05 Akim Demaille <akim@epita.fr>
7119 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7120 directories when descending in a SUBDIRS.
7121 Reported by Ezra Peisach.
7123 2002-04-04 Andreas Schwab <schwab@suse.de>
7125 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7126 contains no literal separators.
7128 2002-04-03 Akim Demaille <akim@epita.fr>
7130 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7131 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7132 Use dnl, not the KILL diversion.
7133 Extracted from...
7134 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7135 (AC_CONFIG_LINKS): here.
7136 Adjust.
7137 Don't use the KILL diversion, as it kills spurious output, which
7138 results in failures being hidden.
7139 Use m4_defn where appropriate.
7140 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7141 after the second argument.
7142 Use m4_defn.
7143 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7144 syntax, as it is provided by M4sugar.
7145 * tests/torture.at (Multiple AC_CONFIG_FILES): New.

7149 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

7153 aclocal.
7155 2002-04-03 Akim Demaille <akim@epita.fr>
7157 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
7158 (_AC_COMPILER_EXEEXT_REJECT): New.

7160 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)

7162 Fixes Debian #138666.

7166 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7168 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.

7182 _AS_MKDIR_P_PREPARE.
7184 2002-03-28 Kevin Ryde <user42@zip.com.au>
7186 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7187 to avoid versions of HP C which don't allow that.
7189 2002-03-27 Paul Eggert <eggert@twinsun.com>
7191 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7192 (AS_SHELL_SANITIZE): Invoke it.

7199 2002-03-26 Akim Demaille <akim@epita.fr>
7201 * doc/autoconf.texi (Introduction): The GNATS base moved.
7203 2002-03-25 Paul Eggert <eggert@twinsun.com>
7205 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7206 as POSIX requires, as it doesn't work with Zsh.
7207 * doc/autoconf.texi (Assignments): Document the problem.
7209 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7211 * doc/autoconf.texi (Limitations of Make): Mention more issue
7212 about VPATH, overriding of macros in sub-makes, and handling of
7213 SHELL.
7215 2002-03-21 Paul Eggert <eggert@twinsun.com>
7217 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7218 problem with here-document buffer boundaries.
7220 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7221 when reinvoking the shell, to work around problems with installers
7222 who put strange things like "cd" commands in their environments.
7224 2002-03-19 Akim Demaille <akim@epita.fr>
7226 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7227 From Aaron Ucko.
7229 2002-03-19 Akim Demaille <akim@epita.fr>
7231 * bin/autoscan.in (scan_file): Specify the location in `&used'
7232 invocations.
7233 From Nicolas Joly.
7235 2002-03-19 Akim Demaille <akim@epita.fr>
7237 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7238 From Nishio Futoshi.
7240 2002-03-19 Akim Demaille <akim@epita.fr>
7242 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7244 2002-03-18 Paul Eggert <eggert@twinsun.com>
7246 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7247 (Limitations of Usual Tools): Add mkdir section.
7249 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7250 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7251 back on AS_DIRNAME to compute prefixes otherwise; this is
7252 roughly what mkinstalldirs does. That way, we need not have
7253 our own filename disassembler. The old disassembler did not
7254 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7256 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7257 Create at_test_all by a series of assignments,
7258 not by a single assignment of a long string. The latter causes ksh
7259 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7260 presumably because of a buffer overrun.
7262 2002-03-14 Paul Eggert <eggert@twinsun.com>
7264 * lib/autotest/general.m4 (at_times_skip):
7265 Renamed from at_times. Now a boolean.
7266 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7267 says 'times: not found'.
7269 2002-03-14 Akim Demaille <akim@epita.fr>
7271 * bin/autoreconf.in (&study_gettextize): New.
7272 (&autoreconf): Handle newest gettextize.
7273 Rerun aclocal if needed.
7274 Suggested by Andreas Schwab.
7276 2002-03-13 Akim Demaille <akim@epita.fr>
7278 * doc/autoconf.texi (Special Shell Variables): More about IFS.
7280 2002-03-13 Akim Demaille <akim@epita.fr>
7282 * doc/autoconf.texi (Header Portability): New.
7283 Add information about stdint.h and inttypes.h from Paul Eggert.
7285 2002-03-13 Akim Demaille <akim@epita.fr>
7287 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7288 -p'.
7289 From Bob Proulx.
7291 2002-03-12 Akim Demaille <akim@epita.fr>
7293 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7294 m4_require.
7296 2002-03-11 Andreas Schwab <schwab@suse.de>
7298 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7299 does not do it if --with-lispdir is given.
7301 2002-03-08 Akim Demaille <akim@epita.fr>
7303 Version 2.53.
7305 2002-03-08 Akim Demaille <akim@epita.fr>
7307 * doc/autoconf.texi (Subdirectories): Clarify that the
7308 subdirectory should exist.
7310 2002-03-08 Akim Demaille <akim@epita.fr>
7312 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7314 2002-03-08 Akim Demaille <akim@epita.fr>
7316 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7317 aliases the actual variables, and modifications of the former
7318 affect the latter.
7320 2002-03-08 Akim Demaille <akim@epita.fr>
7322 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7323 because of C-c: have m4 output in tmp files, then mv them.
7325 2002-03-08 Akim Demaille <akim@epita.fr>
7327 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7328 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7329 * bin/ifnames.in: Copyright update.

7335 2002-03-05 Akim Demaille <akim@epita.fr>
7337 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7338 Kevin Ryde.

7346 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7347 * lib/autoconf/general.m4 (AC_INIT): More informative error
7348 message for LIBOBJ.
7350 2002-03-04 Akim Demaille <akim@epita.fr>
7352 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7353 parallel builds.
7355 2002-03-04 Akim Demaille <akim@epita.fr>
7357 * doc/autoconf.texi (Transforming Names): Equality between target
7358 and host is irrelevant.
7359 (Specifying Names, Canonicalizing): Remove all references to the
7360 backward compatibility hooks. Rather, collect them all into...
7361 (Hosts and Cross-Compilation): this new section.
7362 * doc/install.texi (System Type): Ditto.
7363 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

7368 * doc/autoconf.texi (Evaluation Macros): New.
7369 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7370 useless.
7371 (_m4_foreach): Define the variant with immediate evaluation so
7372 that it contains exactly the items, not an expression which
7373 evaluation is the current item.
7374 (m4_re_string, m4_re_word): Don't over quote them.
7376 2002-03-04 Akim Demaille <akim@epita.fr>
7378 Instead of having stacking `shift's evaluated at the end, let
7379 `foreach' loops immediately evaluate them.
7381 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7382 $*. This is the n-th time I change my mind, but hopefully this is
7383 the last...
7384 (m4_lquote): New.
7385 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7386 efficient.
7387 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7388 it was only a hack for m4_text_wrap.
7389 (m4_car2): Remove, replaced by...
7390 (m4_cdr): New.
7391 (_m4_foreach): Adjust.
7392 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7393 m4_bpatsubst for clarification.

7444 Fix Autoconf PR/207:
7445 AC_PREFIX_PROGRAM fails with dashed program names
7447 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7448 variable when looking for the prefix program.
7449 Now it also works for shell variables.

7454 case/esac.

7486 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

7508 * bin/autom4te.in (&parse_args): Implement `frozen files are
7509 optional are the sum of the previous files on the command line'.
7510 Also, pass `--reload-state=' on them, so...
7511 (handle_m4): don't.
7512 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.

7523 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7524 alphanumeric to `-' instead of `_'.
7526 2002-01-30 Akim Demaille <akim@epita.fr>
7528 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7529 for plain code, the other for cross-compilation code. The latter
7530 is now run with GCC only.
7531 * doc/autoconf.texi (Compilers and Preprocessors): New.
7533 2002-01-30 Akim Demaille <akim@epita.fr>
7535 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7536 values.
7537 * doc/autoconf.texi (Initializing configure): Explain how to
7538 change AC_INIT default values.
7540 2002-01-29 Akim Demaille <akim@epita.fr>
7542 * tests/torture.at (Configuring subdirectories): Use configure.in,
7543 so that aclocal 1.4 works.
7544 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7546 2002-01-28 Akim Demaille <akim@epita.fr>
7548 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7549 needs an argument.
7551 2002-01-28 Akim Demaille <akim@epita.fr>
7553 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7554 AUTOTEST_PATH *after* it was set.
7555 Don't put `.' in the PATH: the user should be precise and `./' if
7556 needed. In addition, given that the test suite does some `cd', if
7557 `.' is in the path, the `tested programs' sections will report
7558 programs found in the test suite's directory, while during the
7559 tests (performed in their own directory), these programs are no
7560 longer visible. In other words, the results is confusing and
7561 useless.
7562 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7564 2002-01-24 Akim Demaille <akim@epita.fr>
7566 Version 2.52g.
7568 2002-01-24 Akim Demaille <akim@epita.fr>
7570 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
7571 * doc/autoconf.texi: Finally add Akim as an author.
7573 2002-01-24 Akim Demaille <akim@epita.fr>
7575 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7576 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7577 Bourne. Use /bin/sh.
7578 From Andreas Buening.
7580 2002-01-24 Akim Demaille <akim@epita.fr>
7582 * config/config.guess, config/config.sub, config/texinfo.tex:
7583 Update from masters.
7585 2002-01-24 Akim Demaille <akim@epita.fr>
7587 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
7588 * config/auxdir.m4, config/cond.m4, config/depend.m4,
7589 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
7590 * config/missing.m4, config/sanity.m4, config/select.m4,
7591 * config/strip.m4: Remove, to ease sync'ing with any version of
7592 Automake.
7594 2002-01-24 Akim Demaille <akim@epita.fr>
7596 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7597 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7598 Reported by Geir Ove Myhr.
7600 2002-01-21 Akim Demaille <akim@epita.fr>
7602 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7604 2002-01-21 Akim Demaille <akim@epita.fr>
7606 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7607 message on invalid options.
7608 * bin/autom4te.in (parse_args): Don't use
7609 Autoconf::General::getopt with non valid options.
7611 2002-01-17 Jim Meyering <meyering@lucent.com>
7613 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7614 $ac_cv_exeext so we don't use an old, invalid, cached value.
7616 2002-01-11 Akim Demaille <akim@epita.fr>
7618 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7619 Meyering.

7625 2002-01-06 Akim Demaille <akim@epita.fr>
7627 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7628 package.m4, since is really depends upon configure.ac, not
7629 configure.
7630 * doc/autoconf.texi (testsuite Scripts): Adjust.
7631 * tests/Makefile.am (package.m4): New.
7632 EXTRA_DIST it since its a source.
7634 2002-01-06 Akim Demaille <akim@epita.fr>
7636 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7637 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7638 and PACKAGE_BUGREPORT from here...
7639 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7640 arguments.
7641 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7642 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7643 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7644 * tests/tools.at (autoheader): Adjust.
7645 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7647 2002-01-06 Akim Demaille <akim@epita.fr>
7649 * bin/autoscan.in (scan_file): Use `&used'.
7651 2002-01-03 Akim Demaille <akim@epita.fr>
7653 * doc/autoconf.texi (Output): Improved wording regarding use of
7654 AC_OUTPUT.
7655 From Olly Betts.
7657 2001-12-18 Kevin Ryde <user42@zip.com.au>
7659 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7660 sometimes needing writable input.
7662 2001-12-17 Jim Meyering <meyering@lucent.com>
7664 * doc/autoconf.texi (New Macros): Tweak wording.
7666 2001-12-14 Akim Demaille <akim@epita.fr>
7668 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7669 trailing files, don't apply `-rf' to files which might not be
7670 created by configure (core, core.*, and *.core), but just `rm -f'.
7671 Suggested by Jonathan Kamens.
7673 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7675 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7677 2001-12-14 Akim Demaille <akim@epita.fr>
7679 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7681 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7683 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7684 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7685 abs_srcdir, top_srcpath to abs_top_srcdir.
7686 (_AC_OUTPUT_FILES): Adjust.
7687 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7688 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7689 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7691 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
7693 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
7694 C/Fortran linking on HP/UX, by extracting the Fortran library
7695 search path from the LPATH line in the $F77 -v output.
7697 2001-12-12 Kevin Ryde <user42@zip.com.au>
7699 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7700 forbidden file descriptors table.
7702 2001-11-26 Akim Demaille <akim@epita.fr>
7704 * bin/autoscan.in (%c_keywords): Build it at top level.
7705 Map to 1 in order to simplify its uses.
7707 2001-11-26 Akim Demaille <akim@epita.fr>
7709 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7710 Remove $filepath, useless.
7711 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7712 variables, they are really part of the tokens.
7713 Split the input line on spaces and then look for tokens.
7714 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7715 because of `lex$U.$(OBJEXT)'.
7716 (&scan_files): Use "@list" instead of join.
7717 * doc/Makefile.am (CLEANFILES): Add *.fns.
7719 2001-11-26 Akim Demaille <akim@epita.fr>
7721 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
7722 Remove, replaced by...
7723 * tests/wrappl.in: Be common for all the Perl executables.
7724 In particular autoscan and autoheader want -I.
7725 * configure.ac: Adjust.
7726 * lib/autoscan/headers: errno.h is portable.
7728 2001-11-26 Akim Demaille <akim@epita.fr>
7730 * bin/autoscan.in (used): New.
7731 Use it.
7733 2001-11-26 Akim Demaille <akim@epita.fr>
7735 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7736 directives.
7737 (&scan_sh_file): Remove a duplicate pattern.
7738 (&check_configure_ac): Use long options.
7739 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
7741 2001-11-26 Akim Demaille <akim@epita.fr>
7743 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
7744 Before, having a line containing the opening of a multi line
7745 comment made the whole line be ignored.
7747 2001-11-26 Akim Demaille <akim@epita.fr>
7749 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7750 (testsuite Scripts): Be one of its subsection.
7751 (Autotest Logs): New.
7753 2001-11-26 Akim Demaille <akim@epita.fr>
7755 Test groups are now run two directories deeper.
7757 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7758 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7759 at_top_builddir.
7760 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7761 top_srcdir, builddir and top_builddir.
7762 Use `at_*dir' relatively to the directory containing the
7763 suite, use `*dir' when relatively to the current group dir.
7765 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7767 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7768 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7769 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7770 spelling errors.
7772 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7774 * doc/autoconf.texi (Using System Type): Add an example of `case
7775 $host' usage so people quit using `case $target' everywhere.
7777 2001-11-22 Akim Demaille <akim@epita.fr>
7779 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7780 spotted by Jim Meyering.
7782 2001-11-16 Paul Eggert <eggert@twinsun.com>
7784 This patch implements a `long double' suggestion by Oliver Kiddle.
7786 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7787 static, to catch errors if the value isn't known at compile-time
7788 and the compiler supports dynamic arrays. Change its name from
7789 `_array_' to `test_array' to avoid potential name clashes.
7790 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7791 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7792 better than double. Catch a bug in GCC 2.95.2 x86.
7793 * doc/autoconf.texi (C Compiler): Document the above.
7794 * NEWS: Likewise.
7796 2001-11-13 Akim Demaille <akim@epita.fr>
7798 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7799 hand.
7800 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7802 2001-11-13 Akim Demaille <akim@epita.fr>
7804 * lib/autotest/general.m4 (AT_INIT): After having run the test
7805 group, go back to the initial directory, not to at_suite_dir.
7807 2001-11-13 Akim Demaille <akim@epita.fr>
7809 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7810 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7811 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7812 option.
7813 (AT_CHECK_CONFIGURE): Use absolute paths.
7814 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7815 The problem is still the old one: there is no means in M4 (that I
7816 know about) to create a defining macro, because there is no means
7817 to create `$1' etc., therefore, the defining macro ``swallows''
7818 all the arguments meant to the defined macro.
7820 2001-11-13 Akim Demaille <akim@epita.fr>
7822 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7823 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7824 configure.ac.
7825 * tests/aclocal.m4: Remove, as it is no longer used.
7827 2001-11-13 Akim Demaille <akim@epita.fr>
7829 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7830 variable names when referring to a single test group, or to
7831 `suite' when referring to the whole test suite.
7832 `at_last_test' is removed: m4 compute at_format itself.
7833 (at_stdout, at_stder1, at_stderr): New variables.
7834 (AT_CHECK): Use them.
7836 2001-11-13 Akim Demaille <akim@epita.fr>
7838 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7839 in PATH.
7840 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7841 Do it as soon as a test fails, don't wait till the end of the test
7842 suite.
7843 Don't remove $as_me.[0-9]*, since these files no longer exist.
7845 2001-11-13 Akim Demaille <akim@epita.fr>
7847 * tests/tools.at: Use absolute paths, since we are no longer run
7848 in place.
7850 2001-11-13 Akim Demaille <akim@epita.fr>
7852 Now that tests are running in their own private dir, there is no
7853 need to list the files to remove at the end of tests groups.
7855 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7856 (AT_data_files, at_data_files): Remove.
7857 (AT_CLEANUP, AT_DATA): Simplify.
7858 (AT_INIT): Adjust.
7859 Remove the group dir if !debug && !failed.
7860 * tests/atspecific.m4: Adjust.
7862 2001-11-13 Akim Demaille <akim@epita.fr>
7864 Start a new layout for Autotest: `testsuite' creates
7865 `testsuite.dir' in which the at-check-line etc. files are to be
7866 found, and `testsuite.dir/003' where the test group 3 is run.
7868 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7869 at_check_line_file, at_format, at_test_normalized, at_group_dir
7870 are new variables.
7871 Create the directories.
7872 Use absolute paths for at- files.
7873 (AT_CHECK): Adjust.
7875 2001-11-11 Michael Matz <matz@kde.org>
7877 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7878 (m4_car2): New.
7879 (m4_car): Properly quote arguments.
7881 2001-11-13 Akim Demaille <akim@epita.fr>
7883 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7884 with stricter rules on LIBOBJS.
7886 2001-11-12 Paul Eggert <eggert@twinsun.com>
7888 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7889 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7890 __PROTOTYPES too.
7892 2001-11-12 Akim Demaille <akim@epita.fr>
7894 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7896 2001-11-12 Akim Demaille <akim@epita.fr>
7898 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7899 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7900 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7901 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7902 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7903 specify to what the macro should be defined (typically to 1).
7905 2001-11-12 Akim Demaille <akim@epita.fr>
7907 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7908 From Jim Meyering.
7910 2001-11-12 Akim Demaille <akim@epita.fr>
7912 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
7913 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
7914 definition used by Automake where LEX is +/- "${missing} lex" and
7915 `missing' itself contains variables.
7917 2001-11-12 Akim Demaille <akim@epita.fr>
7919 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7920 Now that M4sh pushes BODY, the comments were output at the end of
7921 the test suites.
7923 2001-11-08 Akim Demaille <akim@epita.fr>
7925 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7926 that we can trace macros from aclocal.m4.
7927 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7928 obsoleted, and redirect to the former anyway.
7929 Reported by Ralf Corsepius.
7931 2001-11-08 Akim Demaille <akim@epita.fr>
7933 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
7934 processed only if present.
7935 * tests/torture.at (Configuring subdirectories): Use autoreconf
7936 instead of successive calls to autoconf.
7937 Add a nonexistent subdirectory to exercise the patch above.
7938 Reported by Ralf Corsepius.
7940 2001-11-08 Kevin Ryde <user42@zip.com.au>
7942 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
7943 doesn't accept .S files.
7945 2001-11-07 Akim Demaille <akim@epita.fr>
7947 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

7951 (handle_output): Use it.
7952 Read m4_pattern_forbid with messages.
7954 2001-11-05 Akim Demaille <akim@epita.fr>
7956 * bin/autom4te.in (--normalize): Remove.
7957 * lib/autom4te.in: Adjust.
7959 2001-11-05 Akim Demaille <akim@epita.fr>
7961 * tests/Makefile.am (testsuite): Rename this target as...
7962 ($(TESTSUITE)): this.
7963 From Nicolas Joly.
7965 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
7967 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
7968 the --prefix option, also remove it's argument.
7970 2001-11-05 Akim Demaille <akim@epita.fr>
7972 * doc/autoconf.texi (testsuite Invocation): Update.
7973 (Writing testsuite.at): Update.
7975 2001-11-03 Akim Demaille <akim@epita.fr>
7977 * doc/autoconf.texi: s/@code/@command/ where appropriate.
7979 2001-11-03 Akim Demaille <akim@epita.fr>
7981 * lib/Autom4te/General.pm: (&catfile, &canonfile)
7982 (&file_name_is_absolute): New, wrappers around routines from
7983 File::Spec.
7984 Use and export them.
7985 (&find_configure_ac): Optionally take a directory where to look at.
7986 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
7987 the arguments.
7988 Default @ARGV to `.', not find_configure_ac.
7989 (&autoreconf): Argument is a directory.
7990 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
7991 * doc/autoconf.texi (autoreconf Invocation): Update.
7993 2001-11-03 Akim Demaille <akim@epita.fr>
7995 * lib/Autom4te/General.pm (@export_vars, @export_subs)
7996 (@export_forward_subs): New.
7997 Add basename, dirname, and fileparse.
7998 (@EXPORT): Adjust.
7999 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8000 Don't look for aclocal flags if we already know aclocal is not
8001 used.
8002 Move aclocal.m4t only if it exists.
8003 Reported by Ezra Peisach.
8005 2001-11-03 Akim Demaille <akim@epita.fr>
8007 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8008 passed on command line, defaulting to ./configure.ac if present.
8009 (&maybe_autoreconf, File::Find): Remove, unused.
8010 (&autoreconf): If autoconf is not used, don't try to trace.
8012 2001-11-02 Akim Demaille <akim@epita.fr>
8014 * configure.ac: Bump to 2.52g.
8016 2001-11-02 Akim Demaille <akim@epita.fr>
8018 Version 2.52f.
8020 2001-11-02 Akim Demaille <akim@epita.fr>
8022 * config/config.guess, config/config.sub, doc/standards.texi:
8023 * config/lispdir.m4: Update from masters.
8024 * configure.ac: Bump to 2.52f.
8026 2001-11-02 Akim Demaille <akim@epita.fr>
8028 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8029 Don't run aclocal when aclocal.m4 is not from aclocal.
8030 From Ezra Peisach.
8031 Don't run libtoolize and gettextize if --install is not given.
8033 2001-11-01 Paul Eggert <eggert@twinsun.com>
8035 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8036 be invoked before _AS_LINENO_PREPARE.
8037 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8038 than character ranges.
8040 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8041 invoking AS_BASENAME. Set the locale variables to 'C' if
8042 possible, as POSIX requires this to get the traditional
8043 behavior.
8044 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8046 2001-10-31 Paul Eggert <eggert@twinsun.com>
8048 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8049 with {}, as that triggers a bug in Bash 2.05.
8051 (_AS_LINENO_PREPARE): Use Sed rather than
8052 Awk. Fix the sed prepass to work even if there are multiple
8053 instances of $LINENO on the same line. Do not substitute for
8054 other variables like $LINENOT. Do not check file dates; such a
8055 check is unreliable on sufficiently fast machines, and removing
8056 the check makes the code simpler and more reliable. Check for
8057 output and chmod failures.
8059 * doc/autoconf.texi (Special Shell Variables): Document
8060 the above.
8062 2001-10-31 Akim Demaille <akim@epita.fr>
8064 * tests/Makefile.am (atconfig): Remove this target, Automake
8065 handles it now.
8067 2001-10-31 Akim Demaille <akim@epita.fr>
8069 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8070 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8071 provided, while it is optional.
8072 * configure.ac: Adjust.
8074 2001-10-26 Paul Eggert <eggert@twinsun.com>
8076 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8077 lib/Autom4te/Struct.pm:
8078 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8079 with 5.005_02.
8081 * doc/autoconf.texi (Special Shell Variables): Document some
8082 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8084 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8085 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8086 eval $LINENO is not portable in practice.
8088 2001-10-24 Akim Demaille <akim@epita.fr>
8090 * lib/Autom4te/General.pm (backname): New.
8092 2001-10-24 Akim Demaille <akim@epita.fr>
8094 * m4/: Remove, merged into...
8095 * config/: here.
8097 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8099 * doc/autoconf.texi (Shellology): Mention the problems with bash
8100 2.05's use of ANSI quoting in its `set' builtin.
8102 2001-10-22 Paul Eggert <eggert@twinsun.com>
8104 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8105 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8106 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8107 POSIX decided to standardize on the int flavor of strerror_r.
8108 Always do char* test, as there's no reason not to.
8109 Assign to a char* var, to catch strerror_r that returns int*.
8111 * doc/autoconf.texi (Particular Functions):
8112 Document the above changes. Also, document the fact that
8113 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8115 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8117 2001-10-20 Akim Demaille <akim@epita.fr>
8119 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8120 the executable was missing from the log.
8122 2001-10-20 Akim Demaille <akim@epita.fr>
8124 * lib/Autom4te/General.pm (&update_file): If destination is
8125 unchanged, remove the source.
8126 (&up_to_date_p): Don't be verbose, be debug.
8127 * bin/autoreconf.in: No longer support --m4dir.
8128 (&autoreconf): Display the full path of the configure.ac we are
8129 studying.
8130 Trace it only once.
8131 Be sure to honor --force with gettextize.
8132 Always run aclocal.
8133 * doc/autoconf.texi: Adjust.
8135 2001-10-20 Akim Demaille <akim@epita.fr>
8137 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8138 Remove, dead.
8139 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8140 `intl' is already present, as it refuses unless --force.
8141 (&parse_args): Use -I, --include instead of the old Autoconf
8142 options.
8143 ($localdir, $autoconf_dir): Remove.
8144 (@include): New.
8145 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8147 2001-10-19 Jens Petersen <petersen@redhat.com>
8149 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

8159 2001-10-19 Akim Demaille <akim@epita.fr>
8161 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
8162 comment, explain how to install automatic mode selection.
8163 From Russ Allbery.
8165 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8167 * bin/autoreconf.in (autoreconf): Display the path to the
8168 configure.ac being studied.
8170 2001-10-18 Paul Eggert <eggert@twinsun.com>
8172 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8173 long, to work around a bug in the HP C compiler version HP92453-01
8174 B.11.11.23709.GP.
8176 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8177 (AS_BASENAME_EXPR): New macro.
8178 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8179 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8180 and fall back on 'sed' only if the other two fail. This makes
8181 AS_BASENAME act more like AS_DIRNAME.
8182 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8183 contains white space.
8184 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8185 Use AS_DIRNAME, since I think it's now DOS-friendly.
8186 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8187 Allow "dirname //FOO" to return either / or //, as POSIX allows
8188 either behavior.
8190 2001-10-10 Akim Demaille <akim@epita.fr>
8192 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8193 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8194 From Eric Sharkey.

8198 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

8202 2001-10-10 Akim Demaille <akim@epita.fr>
8204 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

8235 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
8236 (Syntax of the shell scripts): Don't.
8237 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
8238 bother with $force since...
8239 * lib/Autom4te/General.pm: does.
8241 2001-10-08 Akim Demaille <akim@epita.fr>
8243 * bin/autoreconf.in: Rewrite in Perl.
8244 * configure.ac: Adjust.

8313 include handle the m4_pattern_*, no longer push the

8316 * tests/base.at: Adjust the tests to use AS_INIT.
8317 * tests/tools.at (AT_DATA_FORBIDDEN): New.

8324 CONFIG_SHELL defaults to a shell that supports LINENO if available.
8326 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
8327 shell does not support LINENO, and if CONFIG_SHELL is unset or
8328 empty, and if we can find a shell that does support LINENO,
8329 then set CONFIG_SHELL to that shell and then re-execute
8330 ourselves with CONFIG_SHELL.
8332 2001-10-05 Paul Eggert <eggert@twinsun.com>
8334 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8335 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8336 build of $(TESTSUITE).
8338 2001-10-05 Akim Demaille <akim@epita.fr>
8340 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8361 (AS_SHELL_SANITIZE): here. Use it.

8363 From Paul Eggert.
8365 2001-10-04 Akim Demaille <akim@epita.fr>
8367 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
8368 combination of Awk and sed to replace $LINENO.

8377 compatibility with POSIX shells.

8403 2001-09-30 Paul Eggert <eggert@twinsun.com>
8405 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
8406 Don't use nested parenthesization. This patch was originally
8407 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
8408 but somehow it didn't get incorporated then.
8409 * doc/autoconf.texi (Limitations of Usual Tools):
8410 Clarify remark about sed and nested parenthesization.
8412 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
8413 Report an error if the size cannot be determined even though
8414 the type exists.
8415 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8416 Check for `expr' arithmetic overflow, and for compilation failure,
8417 and invoke a new argument $4 if either is discovered.
8418 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
8419 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
8421 2001-09-28 Akim Demaille <akim@epita.fr>
8423 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

8427 2001-09-28 Akim Demaille <akim@epita.fr>
8429 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
8430 (AT_TESTED): this.
8431 (AT_INIT): More the wrapped section to where it will be expanded.
8432 Output `AT_tested' only when existing.
8433 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
8435 2001-09-27 Akim Demaille <akim@epita.fr>
8437 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that

8441 status when executing the ACTION-IF-FALSE.
8442 * tests/base.at (AC_TRY_*): Rename as...

8444 (AC_RUN_IFELSE): New.
8445 * tests/compile.at (Extensions, C keywords)
8446 (AC_PROG_CPP requires AC_PROG_CC, GNU Fortran 77)
8447 (Broken/missing compilers, AC_PROG_CPP with warnings)
8448 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
8449 * tests/c.at (Extensions, C keywords)
8450 (Broken/missing compilers, AC_PROG_CPP with warnings)
8451 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
8452 (AC_PROG_CPP requires AC_PROG_CC): here and...
8453 * tests/fortran.at (GNU Fortran 77): there.
8454 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8455 AC_TRY_RUN is about compilation, not shell commands.
8456 (Test Programs): AC_TRY_RUN works as used to be advertised.
8458 2001-09-27 Akim Demaille <akim@epita.fr>
8460 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8461 Raja R Harinath:
8462 Be sure to detect when $LINENO always returns the same value.
8463 Look for the original script, basename($0) is certainly not
8464 enough.
8465 Pass the CLI arguments to `$as_me.lineno'.
8467 2001-09-25 Akim Demaille <akim@epita.fr>
8469 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
8470 Be sure the close and reopen the LOG fd before and after using tee
8471 to extend the log.
8472 <at_tests_pattern>: Adjust to the new format of at_help_all.
8474 2001-09-23 Akim Demaille <akim@epita.fr>
8476 * bin/autom4te.in (parse_args): There can be several invocations
8477 of --language now.

8560 * tests/Makefile.am (package.m4): Remove.
8562 2001-09-22 Akim Demaille <akim@epita.fr>

8567 `$LINENO' support replacement when not supported.
8568 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

8605 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8606 be used instead of ':'.
8607 * lib/autotest/general.m4: Replace occurrences of ':' in

8637 * lib/autotest/general.m4: Englishoes.
8638 From Tim Van Holder and Alexey Mahotkin.
8640 2001-09-18 Paul Eggert <eggert@twinsun.com>
8642 * doc/autoconf.texi (Common Shell Constructs): New node,
8643 documenting AS_DIRNAME.
8644 (Limitations of Usual Tools): Refer to it when discussing dirname.
8645 Also, update discussion of POSIX standard to reflect latest draft.
8647 * lib/autoconf/c.m4:
8648 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8650 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8651 Do not pass a first argument with leading '-'
8652 to expr, by parenthesizing initial integers that might be negative.
8654 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8655 now merely checks whether it is an error to pass an argument
8656 to getpgrp.
8658 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8659 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8660 whether it is a (compile-time) error to pass an argument to
8661 getpgrp. This simpler test supports the revised documentation,
8662 and is all that AC_FUNC_GETPGRP's users really need.

8676 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8677 correctly.
8678 Add test for AS_BASENAME.
8679 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8680 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8681 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8682 * tests/base.at: Fixed the expected responses. The old ones were
8683 one line out...
8684 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8685 the documentation claims it should (and how it behaved in 2.13).
8687 2001-09-18 Akim Demaille <akim@epita.fr>
8689 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8690 the AC_CONFIG_COMMANDS invocation.
8691 This also solves the name clash problems.
8692 Don't set the package's ID.
8693 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8694 No longer to be shipped.
8695 (version.in): Remove.

8697 * lib/autoconf/status.m4: Adjust.
8698 Use `m4_PACKAGE_STRING'.
8699 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8700 the only optional argument is the name of the test suite.
8701 Expect `package.m4' to define the package signature.
8702 * lib/autom4te.in (Autotest): Add `package.m4?'.
8703 * tests/Makefile.am (package.m4): New.
8704 * tests/suite.at: ifnames is a victim.
8706 2001-09-18 Akim Demaille <akim@epita.fr>
8708 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8709 AC_LIBSOURCE, AC_CONFIG_FILES.
8710 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8711 program version string doesn't match the package's.
8712 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8713 after `(cached)'.
8715 2001-09-17 Paul Eggert <eggert@twinsun.com>
8717 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8718 Allow expression to return any value that can fit into unsigned long
8719 (not int, as before). Check for output errors.
8721 2001-09-17 Bruno Haible <haible@ilog.fr>
8723 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8724 Always include <stdio.h> and <stdlib.h>. Evaluate
8725 the expression in an extra function before these includes. Call
8726 fprintf "%d" only after ensuring the argument is of type 'int'.
8727 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8729 2001-09-17 Paul Eggert <eggert@twinsun.com>
8731 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8732 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8733 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8734 when they don't exist.
8736 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8737 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8738 need it.
8740 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8741 version with the version used by fileutils 4.1, except use
8742 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8743 we don't need it.
8745 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8747 2001-09-13 Akim Demaille <akim@epita.fr>

8750 _first_.

8755 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8783 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8785 2001-09-13 Akim Demaille <akim@epita.fr>
8787 * lib/autotest/general.m4 (AT_INIT): Create and remove
8788 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8789 test suites can cohabit.
8791 2001-09-13 Akim Demaille <akim@epita.fr>
8793 * tests/mktests.sh: Don't output banners for empty test files.
8795 2001-09-13 Akim Demaille <akim@epita.fr>

8845 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

8866 related variables into `at_package_*'.

8893 From Uwe Seimet.

8899 2001-09-05 Akim Demaille <akim@epita.fr>
8901 Be ready to handle filenames as stupid as `dnl.at', for if even
8902 the maintainer is dumb enough to do that...
8904 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8905 excellence in M4 quotation: consider `__file__' is active.
8907 And BTW, when invoking m4, pass the --include in the right order:
8908 the wrong one.
8910 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

8955 2001-08-31 Akim Demaille <akim@epita.fr>
8957 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
8958 serious problems handling heredocs in heredocs.
8959 Reported by Nicolas Joly.
8961 2001-08-31 Akim Demaille <akim@epita.fr>
8963 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
8964 (Making testsuite Scripts): Update.
8966 2001-08-31 Akim Demaille <akim@epita.fr>
8968 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
8970 2001-08-31 Akim Demaille <akim@epita.fr>
8972 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
8973 (testsuite Scripts): There is no such thing as `atconfig.in'.
8974 And actually one diagram is missing: test suite runtime.
8976 2001-08-31 Akim Demaille <akim@epita.fr>
8978 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
8979 inverse order.
8981 2001-08-31 Akim Demaille <akim@epita.fr>
8983 * bin/autoupdate.in (@include): `installcheck' revealed the path
8984 to m4sugar was lacking!
8986 2001-08-31 Akim Demaille <akim@epita.fr>
8988 * man/Makefile.am (.x.1): We really have to pass
8989 autom4te_perllibdir.
8991 2001-08-31 Akim Demaille <akim@epita.fr>
8993 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
8994 debug scripts, in particular passing explicitly listed tests to
8995 run is stupid.
8997 2001-08-31 Akim Demaille <akim@epita.fr>
8999 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9000 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9001 Use directly autom4te, not autoconf.
9002 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9004 2001-08-31 Akim Demaille <akim@epita.fr>
9006 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9007 * bin/autoheader.in (%symbol): Strip arguments of macros.
9009 2001-08-31 Akim Demaille <akim@epita.fr>
9011 * doc/autoconf.texi: Catch up -I, --include changes.
9013 2001-08-31 Akim Demaille <akim@epita.fr>
9015 * bin/autom4te.in (&parse_args): Die on unknown languages.
9016 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9017 need for autoconf.
9018 Promote --include over --macrodir and other obsolete options.
9020 2001-08-31 Akim Demaille <akim@epita.fr>
9022 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9023 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9024 * bin/autom4te.in ($autoconf): Pass --force.
9025 `print $out' doesn't print `$_' but `$out'.
9026 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9027 (autoheader): Pass --force since the test suite goes too fast for
9028 the time stamps.
9029 Adjust to the new autoheader messages.
9031 2001-08-31 Akim Demaille <akim@epita.fr>
9033 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9034 Check the completeness of the #template.
9035 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9036 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9037 invocation.
9039 2001-08-31 Akim Demaille <akim@epita.fr>
9041 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9042 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9043 Drop AC_MACRODIR dead for real.
9044 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9045 `autoheader: `config.hin' is created'.
9046 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9048 2001-08-31 Akim Demaille <akim@epita.fr>
9050 * bin/autoheader.in: Rewrite in Perl.
9051 * tests/autoheader: Adjust.
9053 2001-08-31 Akim Demaille <akim@epita.fr>
9055 * bin/autoconf.in (--include, -I): New option.
9056 Map --localdir, --autoconf-dir onto it.
9057 Forward autom4te's options instead of interpreting them.
9058 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9059 There is no such envvar since the inception of autom4te.cfg.
9060 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9061 * bin/autoupdate.in: Adjust, and perform more control.
9062 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9063 * tests/autoconf: Dittowise.
9065 2001-08-31 Akim Demaille <akim@epita.fr>
9067 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9068 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9069 optionally `FILE'.
9070 Use -e, not -f, since /dev/null for instance is OK.
9071 (&parse_args): Adjust.
9072 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9074 2001-08-31 Akim Demaille <akim@epita.fr>
9076 * configure.ac: Also find tested executables in bin.
9077 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9078 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9079 installed peer executables, only PATH is allowed to resolve it.
9080 Pass `autoconf_dir' via options, not via invisible envvars.
9081 * lib/Autom4te/General.pm (&find_peer): Remove.
9082 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9083 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9084 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9085 find the executables for it.
9086 * tests/Makefile.am: Major cleanup. Too lazy to document...
9087 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9088 We only need PERL.
9089 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9090 indeed related to running the test suite, while passing
9091 --autoconf-dir and others is related to running non installed
9092 Autoconf executables. So don't do that, leave it to...
9093 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9094 * tests/autoscan: New.
9095 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9096 refer to library files: rely on --language.
9098 2001-08-29 Akim Demaille <akim@epita.fr>
9100 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9101 s/--set/--language/.
9103 2001-08-29 Akim Demaille <akim@epita.fr>
9105 * doc/autoconf.texi: Strip the @nodes.
9106 Suggested by Paul Eggert.
9107 (Initializing configure): Typo.
9109 2001-08-29 Akim Demaille <akim@epita.fr>
9111 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9112 Suggested by Paul Eggert.
9114 2001-08-29 Akim Demaille <akim@epita.fr>
9116 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9117 download in a tmp dir.
9119 2001-08-29 Akim Demaille <akim@epita.fr>
9121 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9122 case insensitive OSes out there :(
9123 From Tim Van Holder.
9125 2001-08-29 Akim Demaille <akim@epita.fr>
9127 * lib/autom4te.in: New.
9128 * lib/Makefile.am (edit, autom4te.cfg): New.
9129 * bin/autom4te.in (BEGIN): Simplify.
9130 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

9132 (&parse_args): Support --mode, --set, and --melt.
9133 * bin/autoconf.in: Simplify and adjust.
9134 * tests/Makefile.am (AUTOMAKE): Use --set.
9135 * tests/atlocal.in: Adjust.
9136 * BUGS: distcheck and check are weak.
9138 2001-08-29 Akim Demaille <akim@epita.fr>
9140 * lib/autotest/general.m4: Use
9141 foo=`(command) 2>/dev/null`
9142 not
9143 foo=`command` 2>/dev/null
9144 (at-devnull): Rename as...
9145 (AT-devnull): this.
9146 (--clean): Remove AT-* files too.
9147 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
9148 Reported by Nicolas Joly.
9150 2001-08-28 Akim Demaille <akim@epita.fr>
9152 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

9160 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
9162 * lib/autotest/general.m4: Reword some messages.
9163 (AT_INIT): Check for the `times' builtin before using it.
9164 Support test ranges as arguments to the testsuite.
9165 Have -e imply -d as the help text suggested.
9167 2001-08-27 Akim Demaille <akim@epita.fr>
9169 * Makefile.maint: Formatting changes.

9180 2001-08-27 Akim Demaille <akim@epita.fr>
9182 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9183 Support `VAR=VAL' as arguments.
9184 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
9185 may be set via the command line.
9187 2001-08-27 Akim Demaille <akim@epita.fr>
9189 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

9191 first the build dirs, then the src dirs.

9201 2001-08-27 Akim Demaille <akim@epita.fr>
9203 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
9204 `ac_top_builddir' to mimic Automake's vocabulary, which much more
9205 readable.
9206 Adjust callers.
9207 * doc/autoconf.texi (Configuration Actions): Document the vars
9208 available in commands.
9209 Emphasize the risks of collisions in init-cmds.

9213 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
9214 (Initializing configure): this new node.
9216 2001-08-27 Akim Demaille <akim@epita.fr>

9239 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
9240 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
9241 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
9242 -> ac_dir).
9243 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
9244 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

9271 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
9272 (AMTAR): Help automake define it.
9273 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
9274 needed, 1.5 can have a macro and a target with the same name.
9275 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
9276 * m4/strip.m4: New.

9291 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9292 the name of the directory they're in, instead of the filename,
9293 since version.m4 is now in m4sugar, but m4_acversion must not be
9294 classified as an Autoconf macro.
9295 ($input_m4): Don't qualify the path to m4sugar.
9296 Rather, pass autoconf_dir to m4.
9297 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

9312 of config.log on traps.
9313 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
9314 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
9315 for config.status'.
9316 Open the log as soon as possible.
9317 Use the same log introduction as configure's.
9319 2001-08-22 Paul Eggert <eggert@twinsun.com>
9321 * doc/autoconf.texi (Indices): New node.
9322 Move indices out of the top level menu and into this submenu.

9326 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9327 AC_TRY_COMMAND.
9328 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
9330 2001-08-22 Akim Demaille <akim@epita.fr>
9332 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

9369 * configure.ac (AT_CONFIG): Fix the path.
9370 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
9371 can be used.
9373 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
9375 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
9376 program with AC_LANG_PROGRAM before feeding it to
9377 AC_COMPILE_IFELSE. Cleanup grep usage.
9379 2001-08-20 Akim Demaille <akim@epita.fr>
9381 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9382 * NEWS, README, README-alpha, TODO, tests/README: This package is
9383 `Autoconf', not `autoconf' (the executable).
9385 2001-08-20 Akim Demaille <akim@epita.fr>
9387 Info readers seem to need `Index' in the index node title :(
9389 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9390 simplified index node names.
9392 2001-08-20 Akim Demaille <akim@epita.fr>
9394 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
9395 arguments are not literals.
9396 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
9397 Specify the output variables, and macros defined.
9399 2001-08-20 Akim Demaille <akim@epita.fr>
9401 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
9402 (Examining Syntax) <AC_TRY_COMPILE>
9403 (Examining Libraries) <AC_TRY_LINK>
9404 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
9405 their arguments.

9434 2001-08-20 Akim Demaille <akim@epita.fr>
9436 Huh!?!?! There are still some user EOF tags used, which prevents
9437 their use in AC_CONFIG_COMMANDS for instance...
9439 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
9440 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

9503 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9504 `$0.log' as for projects where testsuite is in src, we'd have
9505 testsuite.log created in src.
9507 2001-08-17 Akim Demaille <akim@epita.fr>
9509 * bin/autom4te.in (&parse_args): Recognize --normalize.

9519 2001-08-17 Akim Demaille <akim@epita.fr>
9521 * doc/autoconf.texi: Work around Texinfo buglets.
9522 (Transformation Rules): One example is enough, users are expected
9523 to have their brains on. And BTW, use DESTDIR.
9524 (dvar): New macro. Use it.
9526 2001-08-17 Akim Demaille <akim@epita.fr>
9528 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

9561 * doc/install.texi: Use @command.
9562 (Environment Variables): Rename as...
9563 (Defining Variables): this.
9565 2001-08-15 Akim Demaille <akim@epita.fr>
9567 * doc/autoconf.texi (Function Portability): sprintf's return
9568 value.
9569 From Kevin Ryde.
9571 2001-08-15 Akim Demaille <akim@epita.fr>
9573 * Makefile.maint (CVS): New.
9574 (local-check): Run changelog-check. last.

9576 (cvs-dist): depends upon it.
9578 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9580 * tests/Makefile.am: Use a clean-local rule to remove
9581 autom4te.cache (it's a directory, not a file.
9582 * Makefile.am: Ditto (but maintainer-clean-local).
9584 2001-08-15 Akim Demaille <akim@epita.fr>
9586 * bin/autom4te.in (@m4_warning): New.
9587 (&handle_m4): Use it.
9588 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9589 warnings are issued at each run.
9590 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9591 is in the src tree.
9593 2001-08-15 Akim Demaille <akim@epita.fr>
9595 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9596 don't waste time running `autoupdate --version' works.
9597 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9599 2001-08-13 Akim Demaille <akim@epita.fr>

9654 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9656 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9658 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9660 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9661 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9662 * doc/autoconf.texi (C Compiler Characteristics): Update
9663 documentation for AC_C_BIGENDIAN.
9665 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9667 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9668 magic values from an object file when cross-compiling.
9669 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9671 2001-08-10 Akim Demaille <akim@epita.fr>
9673 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9674 effects.
9675 Suggested by Russ Allbery.
9677 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9679 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9680 current $prefix to the sub-configures.
9682 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9684 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9685 extension (needed on BeOS). Reported by Guido van Rossum.
9687 2001-08-09 Akim Demaille <akim@epita.fr>
9689 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9691 2001-08-07 Akim Demaille <akim@epita.fr>
9693 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9694 removed.
9695 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9696 No need to remove the files before and after the each test, before
9697 each test and at the end of the suite is enough.
9698 Display only the children `times', not the shell's.
9699 If the test failed or was skipped, at-times is not available.
9701 2001-08-07 Akim Demaille <akim@epita.fr>
9703 Always produce testsuite.log, including when there are no
9704 failures. This helps getting information on skipped tests, and
9705 duration of the tests. Err, implement the latter btw.
9707 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9708 Dump information on the first run of each test.
9709 (AT_CLEANUP): Create `at-times' containing the duration of the
9710 test group.
9712 2001-08-07 Akim Demaille <akim@epita.fr>
9714 The use of `dumpstat' revealed that `len' was used although it
9715 should not. m4_text_wrap was using it, but in the Autoconf world
9716 where it is legal. Hence (i) test M4sh in its own world, not
9717 Autoconf's, and (ii), ahem, fix the bug :)
9719 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9720 does not like `' instead of [].
9721 (AT_INIT): Forbid `^_?AT_'.
9722 And don't output such tokens.
9723 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9724 `script.as', and `autom4te.cache'.
9725 Remove `empty' and `macro' which are no longer used.
9726 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9727 * tests/m4sugar.at: Use it.
9728 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9730 2001-08-07 Akim Demaille <akim@epita.fr>
9732 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9734 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9736 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9738 2001-08-04 Akim Demaille <akim@epita.fr>
9740 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9741 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9742 AC_TRY_LINK.
9743 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9744 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9745 (AC_F77_MAIN): Likewise.
9747 2001-08-04 Akim Demaille <akim@epita.fr>
9749 Don't rely on M4sugar outputting the patterns in files, since we
9750 might process the output _without_ running m4, hence without these
9751 files.
9753 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9754 * bin/autom4te.in (@Request::includes): Remove, unused.
9755 (@Request::source): Rename as...
9756 (@Request::input): this.
9757 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9758 (&handle_output): Fetch the patterns from the traces.
9759 `$forbidden' and `$allowed' are constant: use m//o.
9760 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9761 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9763 2001-08-04 Akim Demaille <akim@epita.fr>
9765 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9766 autoconf', i.e., in addition to caching traces, cache the output.
9768 * bin/autom4te.in (Request::cache): Rename as...
9769 (Request::id): this.
9770 ($cache, $icache, $tcache, $ocache): New.
9771 (&handle_m4): Save M4 output in the cache instead of $tmp.
9772 (&handle_output): Adjust.
9773 (&up_to_date_p): Check that the output cache is up to date too.
9774 (top level): Run `&handle_m4' iff force or the cache is invalid.
9775 Run `&handle_output' if the output cache is more recent.
9777 2001-08-04 Akim Demaille <akim@epita.fr>
9779 * bin/autom4te.in ($force): New.
9780 (&parse_args, &print_usage): -f, --force is a new option.
9781 (&handle_output): CPP directives might have spaces after `#'.
9782 (&parse_args): The first file only can be frozen.
9784 2001-08-04 Akim Demaille <akim@epita.fr>
9786 Don't let autom4te compute the `include' traces several times:
9787 first check that the trace cache file is up to date, and then
9788 compare its timestamp with that of the output.
9790 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
9791 the preamble. Don't require 5.005 as Autom4te::General does it,
9792 and better yet (use `use', not `require'!).
9793 * lib/Autom4te/Struct.pm: Rename the last occurrences of
9794 Class::Struct as Autom4te::Struct.
9795 * lib/Autom4te/General.pm (File::stat): Use it.
9796 (&mtime): New, export it.
9797 * bin/autom4te.in: Use it.
9798 Declare `$req' is invalid if it is outdated.
9799 Don't declare it valid before saving it if something went wrong.
9801 2001-08-04 Akim Demaille <akim@epita.fr>
9803 Autom4te shall not encode Autoconf data, and preselecting traces
9804 must be proposed to the users.
9806 * bin/autom4te.in (@required_trace): Remove.
9807 (@preselect): New.
9808 (&parse_args, &print_usage): -p, --preselect is a new option.
9809 (&up_to_date_p): Adjust.
9810 * bin/autoconf.in: Preselect some Autoconf macros.
9812 2001-08-04 Akim Demaille <akim@epita.fr>
9814 * tests/tools.at (autoconf --trace: user macros): Check traces on
9815 macros invoked without arguments, and macros invoked with multiple
9816 lines arguments.
9818 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
9820 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
9821 arguments.
9823 2001-08-03 Akim Demaille <akim@epita.fr>
9825 * bin/autoconf.in ($@): Work around the usual sh bug.
9826 From Nicolas Joly.
9828 2001-08-03 Akim Demaille <akim@epita.fr>
9830 Clean up the handling of the M4 builtins tracing exception.
9832 * bin/autom4te.in (Request::request): Don't complete M4 builtins
9833 trace requests.
9834 (@m4_builtins): Rename as...
9835 (@m4_builtin): this.
9836 (%m4_builtin_alternate_name): New.
9837 (&parse_args): Complete the trace requests with alternate names.
9838 (&handle_traces): Hence no longer do it here.
9839 (&trace_requests): Remove, unused.
9841 2001-08-03 Akim Demaille <akim@epita.fr>
9843 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
9844 m4_if, and m4_wrap.

9849 (m4_divert_pop): Dump the whole diversion stack when a diversion
9850 mismatch happens.
9851 * bin/autom4te.in (&handle_output): Remember of the first
9852 occurrence of a possibly undefined macro, not the last.
9853 Complain about the possibly undefined macros in the same order as
9854 the appear in the output.
9855 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
9856 * tests/tools.at (autoconf: forbidden tokens, basic)
9857 (autoconf: forbidden tokens, exceptions): No longer sort
9858 autoconf's stderr, as it is now deterministic.
9859 Check that `dnl' is caught.
9861 2001-08-01 Akim Demaille <akim@epita.fr>
9863 * configure.ac: Bump to 2.52c.
9865 2001-08-01 Akim Demaille <akim@epita.fr>
9867 Version 2.52b.
9869 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.
9871 2001-08-01 Akim Demaille <akim@epita.fr>

9875 2001-08-01 Akim Demaille <akim@epita.fr>

9878 `die'.
9879 (&END): New.
9880 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
9881 `END', as `Autom4te::General::END' will be triggered.
9882 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
9883 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10275 compiler, not the preprocessor.

10282 2001-07-03 Akim Demaille <akim@epita.fr>

10315 provide an alternate 'main' function name, using the 'main' from

10318 cross-language link tests can be performed successfully.
10319 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10320 after $LIBS, for consistency; this should be the general rule since

10324 2001-06-29 Pavel Roskin <proski@gnu.org>

10327 at-stdout and at-stderr instead of removing the newline
10328 from the echo output, which is not guaranteed to work.
10330 2001-06-28 Jens Petersen <petersen@redhat.com>
10332 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
