3 Sync from Automake, as follows:
5 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6 * config/install-sh: Initialize IFS, so field splitting isn't
7 turned off later.
8 * config/mkinstalldirs: Likewise.
9 * config/missing: Remove superfluous quotes. Replace all uses of
10 `[' by `test', for consistency, and for..
11 * config/missing (sed_minuso, sed_output): New variables.
12 (autom4te, help2man, makeinfo): Use them. Unifies detection of
13 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
14 Fixes `missing' to detect `--output' for help2man. Fixes
15 PR automake/483. Report by Dennis J. Linse.
16 (autom4te): Document in `missing --help'.
18 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
20 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
21 * config/install-sh: Don't use 'path' to talk about file names,
22 as per GNU coding standards. Close a race condition reported by Ralf
23 Wildenhues and Stepan Kasal. There is still a race condition
24 on hosts that predate Posix 1003.1-1992, but we can't help this.
25 Don't mishandle weird characters like space on pre-Posix hosts.
26 Invoke mkdir at most once per dir arg on pre-Posix hosts.
27 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
28 AC_PROG_MKDIR_P from AS_MKDIR_P.
29 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
30 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
31 earlier editions are not (including Automake 1.8.3).
32 Do not suggest mkinstalldirs for thread-safety.
33 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
34 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
35 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
36 presence of special characters and race conditions.
37 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
38 in Autoconf's name space.
40 2006-05-10 Bruno Haible <bruno@clisp.org>
41 and Paul Eggert <eggert@cs.ucla.edu>
43 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
44 from Automake with minor changes.
45 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
47 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
49 * config/install-sh: Update to Automake CVS version, as follows:
50 2006-04-25 Stepan Kasal <kasal@ucw.cz>
51 * lib/install-sh: Simplify the expr implementation of dirname.
52 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
53 * lib/install-sh: Handle --, and diagnose unknown options.
55 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
57 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
58 `./autom4te' to create `./testsuite', since the `all' target
59 will ensure its presence, but `installcheck' should not create
60 the uninstalled wrappers.
62 * tests/torture.at (Unusual Automake input files): Skip if we
63 detect automake < 1.8.
65 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
67 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
68 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
69 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
70 * NEWS: Update.
72 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
74 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
75 munge (multiple) white space and other oddities.
76 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
77 single quotes in variable assignment.
78 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
79 and similar failures by adding multiple spaces, tabs, and other
80 special characters.
81 Report and different test suggested by Francesco Romani
82 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
84 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
85 single quotes, we only need to search for single quotes; this
86 both simplifies the search pattern, and makes us less
87 susceptible to `echo' variations for arguments not containing
88 single quotes.
89 (_AC_ARG_VAR_VALIDATE): Likewise.
91 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
93 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
94 `$*' and IFS concatenation issue with traditional shells and
95 bash-2.04. Report by Seanster@Seanster.com.
97 2006-05-03 Bruno Haible <bruno@clisp.org>
99 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
100 precisely which Mac OS X versions have the od problem.
102 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
104 * doc/autoconf.texi: Use @option systematically.
105 (Integer Overflow):
107 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
108 and Bruno Haible <bruno@clisp.org>
110 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
111 about 'od'.
112 (Integer Overflow): Mention the special case of integer division
113 overflow.
115 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
117 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
118 traditional shells like the Solaris one that do not use the
119 first IFS character for assembling `$*'.
120 Prompted by a related report from autoconf_bug@nro.ca.
122 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
123 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
125 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
126 Mention more problems with the -e option.
128 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
130 * NEWS: Typo.
131 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
133 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
134 in URLs to improve DVI formatted output (requires texinfo 4.6).
135 (System Services, Systemology, Shellology): Likewise.
136 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
137 output.
139 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
140 continuous text.
141 (Runtime): Fix macro argument names to match description:
142 `action-if-found' -> `action-if-true' and similarly.
143 (Obsolete Macros): Likewise.
144 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
145 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
146 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
148 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
150 * doc/autoconf.texi (Limitations of Make): Clean up markup.
152 * ChangeLog: Typo.
153 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
154 DVI output.
156 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
158 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
159 /bin/sh set unsorted output.

165 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
166 (Integer Overflow, Null Pointers, Buffer Overruns):
167 (Floating Point Portability, Exiting Portably): New sections.
168 (Writing Test Programs): Fix some langauge. Recommend exiting
169 with status 1, not merely nonzero. Clarify exit declaration.
170 (Run Time): Move C exit status stuff to new Exiting Portably section.
171 (Systemology): Mention Posix and levenez. Update v7 reference.
172 (Portable Shell): Mention the Posix shell.
174 2006-04-25 Stepan Kasal <kasal@ucw.cz>
176 * bin/autoconf.as (me): Replace by as_me.
178 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
180 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
181 since as_me isn't set yet.
183 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
185 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
186 a few minor bugs in this area.
188 * doc/autoconf.texi (Programming in M4sh): Comment out the
189 documentation of AS_BASENAME, for now.
190 (Shell Substitutions): Do not use AS_DIRNAME in an example.
191 (Limitations of Builtins) <basename>: Do not refer to
192 AS_BASENAME.
193 * bin/autoconf.as (me): Don't use AS_BASENAME.
194 (dir): Remove the unused variable.
195 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
196 AS_DETECT_REQUIRED. All uses changed.
197 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
198 All uses changed.
199 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
200 (AS_BASENAME): Use "basename --" to protect against leading "-".
201 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
202 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
203 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
204 (_AS_DIRNAME_PREPARE): Likewise.
205 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
206 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
207 (AS_DIRNAME): Use "dirname --".
209 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
211 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
212 of "run time" and "run-time" changed to "runtime", for consistency.
213 * lib/autoconf/fortran.m4: Likewise (in comment).
214 * lib/autoconf/functions.m4: Likewise.
215 * lib/autoconf/general.m4: Likewise.
216 * lib/autoconf/headers.m4: Likewise.
218 * doc/autoconf.texi (Run Time): Document the exit status situation
219 with more accuracy and detail.
221 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
223 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
224 Archive is not officially `GNU' any more. Update URL.
225 (Defining Directories): Likewise
226 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
228 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
230 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
231 newline from the `trap' code to finish `config.log'; the NetBSD
232 /bin/sh resets the exit status after an empty command, as
233 documented in doc/autoconf.texi.
234 Reported by Dalibor Topic <robilad@kaffe.org>.
236 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
238 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
239 Suggested by Bruno Haible.
241 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
243 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
244 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
245 Instead, just list the shells that we know work.
246 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
247 changed. Be more cautious about the _cv_ variable.
248 * tests/tools.at (Syntax of the shell scripts): Check the
249 _cv_ variable once, at first, to avoid an internal autoconf error
250 when sh -n does not work.
252 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
254 * lib/Autom4te/FileUtils.pm: Sync from Automake.
256 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
258 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
259 use ">&-" since we're only 99.999% sure that this is portable,
260 and since the MinGW bug is fixed in a different way.
261 * lib/autotest/general.m4 (AT_INIT): Likewise.
263 2006-04-16 Stepan Kasal <kasal@ucw.cz>
265 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
266 before opening config.log, to avoid hitting a bug on MinGW.
268 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
270 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
271 AS_MESSAGE_LOG_FD before reopening it onto the log file.
272 This works around a MinGW bug reported by Eric Paire.
273 Make sure that all writes to the log file append to it,
274 rather than possibly losing data.
275 * lib/autotest/general.m4 (AT_INIT): Likewise.
277 2006-04-14 Stepan Kasal <kasal@ucw.cz>
279 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
280 description.
282 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
284 * NEWS: Update.
286 * configure.ac (AC_INIT): Bump to 2.59d.
288 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
290 Version 2.59c.
292 * Makefile.maint (news-date-check): Do not require a leading `*'
293 before the release date in NEWS.
295 2006-04-12 Stepan Kasal <kasal@ucw.cz>
296 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
298 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
299 the instantiated file do not contain the string 'datarootdir'
300 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
301 @mandir@, replace the reference '${datarootdir}' by the value.
302 * tests/torture.at (datarootdir workaround): New test.
303 * NEWS: Advertise this temporary fixup.
304 Based on a patch by Bruno Haible, reported and analyzed by
305 Paul Eggert and Noah Misch.
307 2006-04-12 Eric Blake <ebb9@byu.net>
309 * tests/autotest.at (Debugging a failed test): Fix comment.
311 2006-04-12 Stepan Kasal <kasal@ucw.cz>
313 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
314 all the changes since 2006-04-07.
316 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
318 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
319 succeeded, but `ln -s file dir' failed, take care to remove the
320 leftover target before the next test, to prevent its spurious
321 failure; also make sure `ln file dir' works before selecting it.
322 Thanks to Keith Marshall for pointing this out.
323 * THANKS: Update.
325 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
326 assignments in `at_debug_args', so that we put them correctly
327 in the `run' script.
328 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
329 Reported by Eric Blake.
331 2006-04-11 Eric Blake <ebb9@byu.net>
333 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
334 top-level tests after micro-suite has been run. Used in...
335 (Debugging a successful test, Debugging script and environment),
336 (Debugging a failed test): ...these new tests. The first of these
337 is fixed by...
338 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
339 macro, split out from...
340 (AT_INIT): ...here, so that using -d also generates a run script.
341 Document that -d inhibits top-level logging.
342 * doc/autoconf.texi (testsuite Invocation): Document that -d only
343 inhibits top-level logging; debug scripts are created.
345 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
346 check.
347 * tests/autotest.at (Empty test, Empty check): New test to check it.
349 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
350 from gcc.
352 2006-04-10 Stepan Kasal <kasal@ucw.cz>
354 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
355 the files if a problem appears. Make the empty *.at files
356 read-only, too. Proposed by Ralf Wildenhues.
358 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
360 * config/Makefile.am: Add comment to force updated Makefile.in.
362 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
363 space only patch to this file, this patch causes the Makefile.in
364 files that include freeze.mk to be updated, and thus have a
365 newer time stamp again, which in turn makes a pristine CVS
366 checkout have correct time stamps.
368 * Makefile.maint (cvs-sv): New macro, to be used..
369 (config.guess-url_prefix, config.sub-url_prefix)
370 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
371 point to CVS text checkout of Gnulib files.
372 (copyright-check): Bump current year.
373 (announcement): Do not hard-wire `./announce-gen'.
374 (cvs-update): Propagate failures of `cvs' and `move-if-change'
375 correctly.
376 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
377 `chmod +x'.
378 (wget_files): Update config.guess, config.sub, texinfo.tex by
379 `wget-update', now that their URLs work again.
381 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
383 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
384 Problem noted by Paul D. Smith.
386 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
388 * doc/autoconf.texi: Remove unused words from word list.
389 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
390 .x-sc_trailing_space: New files.
392 * doc/standards.texi: Sync from gnulib.
394 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
395 `LIBOBJDIR' as experimental.
397 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
398 with a target directory; it's internally implemented as `cp'
399 anyway, but since Autoconf advertises the possibility to use
400 a target directory when LN_S is `ln -s', we need to find out.
401 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
402 analyzed by Keith Marshall <keith.marshall@total.com>.
404 * THANKS: Update.
406 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
408 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
409 confdefs.h as-is. In general, if it has backslash-newline or the
410 like, then it doesn't work either to sort or to remove empty
411 lines.
413 2006-04-09 Stepan Kasal <kasal@ucw.cz>
415 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
417 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
419 * lib/autom4te.in (Automake-preselections): Preselect
420 _AM_SUBST_NOTMAKE.
422 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
424 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
425 apostrophe within a single-quoted string, as this is the usual
426 tradition and is easier to read than '"'"'. Don't rely on the
427 shell treating "$/" like '$/'. Use a more-consistent indenting
428 style for the trap.
430 2006-04-09 Eric Blake <ebb9@byu.net>
432 * tests/autotest.at (Backquote command substitution),
433 (Multiline backquote command substitution): Remove mistaken
434 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
435 applied...
436 (Parenthetical command substitution, Multiline parenthetical
437 command substitution): here.
439 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
441 Import macros from gnulib (often changing their name).
443 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
444 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
445 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
446 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
447 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
448 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
449 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
450 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
451 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
452 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
453 The manual mentions Gnulib more prominently.
454 * doc/autoconf.texi (Gnulib): New node.
455 (Pointers): Add Gnulib URL.
456 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
457 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
458 Gnulib section.
459 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
460 suggest a #define rather than a typedef for _Bool, and mention
461 Gnulib rather than trying to substitute stdbool code.
462 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
463 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
464 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
465 AC_STRUCT_DIRENT_D_TYPE.
466 (Particular Types): Mention stdint.h and inttypes.h as standard
467 headers too.
468 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
469 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
470 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
471 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
472 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
473 (C Compiler): Move AC_C_LONG_DOUBLE to ...
474 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
475 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

516 Revert the patch from 2006-04-01 and only improve
517 _AS_DETECT_BETTER_SHELL:
519 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
520 skip nonexistent directories.
521 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
522 only shell candidates which exist.

527 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
528 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
530 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
531 distinguish m4sugar macros.
532 * tests/tools.at (autoupdating with aclocal and m4_include):
533 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
534 test case by Noah Misch <noah@cs.caltech.edu>.
536 2006-04-07 Stepan Kasal <kasal@ucw.cz>
538 Revert my change from 2006-03-17, in other words:
539 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
540 and DUALCASE=1.
541 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

543 it is set.
545 2006-04-07 Eric Blake <ebb9@byu.net>
547 * doc/autoconf.texi (Programming in M4sh): Document that
548 AS_MKDIR_P exits the script on failure.
549 * lib/autotest/general.m4: Remove redundant AS_ERROR.
551 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
553 * config/elisp-comp, config/install-sh, config/mdate-sh,

568 Eric Blake <ebb9@byu.net>,
569 Paul Eggert <eggert@cs.ucla.edu>,
570 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
572 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
573 whether `set' quotes correctly: redirect stderr of the tested
574 `set', and use a subshell, for Ultrix; use `sed' instead of
575 `grep' for zsh `set' which may write binary output; match only
576 at the beginning of a line, to avoid false positives.
577 In order to avoid false positives by unrelated variables with
578 multiline content, put the dump algorithm in a subshell and
579 unset all variables containing newlines (except some which are
580 special to the shell). Warn about cache variables that are
581 unset.
583 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

594 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
595 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
596 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
597 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
599 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
600 shell issue with double-quoted command substitutions of native

626 ac_config_<foo>s again, sometimes normalized, sometimes not.
627 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
628 (AC_CONFIG_COMMANDS): Do not do so here.
629 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
630 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
631 2005-07-25 rewrite. Noticed by Noah Misch.
633 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
634 _AC_PRESERVE_HELP_ORDER, ...
635 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
637 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
638 inside m4_expand_once; it is redundant.
640 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
641 for --help from Cygnus `configure.'
643 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

691 Use simplified args that Eric Blake originally suggested.
693 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
695 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
696 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
697 Use 'comm' rather than N instances of grep; this also fixes a bug
698 whereby substrings were incorrectly matched, causing us to not
699 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
700 (exclude_list): Exclude empty macros.
701 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
703 Use awk rather than grep -E or egrep, to avoid
704 portability problems with regular expressions containing newlines.

706 Switch from grep to awk syntax.
707 (ac_exclude_script): Renamed from ac_exclude_egrep.

751 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
752 to log, point to testsuite output tree.

782 Clean up _AC_COMPILER_EXEEXT* macros.
784 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
785 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
786 ac_file to the name of the default output filei and call
787 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
788 initial `rm' of the candidate files...
789 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
790 the same list in subsequent `rm' calls, and for the temporary
791 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
792 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
793 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
794 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
795 no longer needed) by libtool. Make it a cache check.

798 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
799 _AC_COMPILER_EXEEXT.

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

856 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.

861 m4sugar macros.
862 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
863 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

869 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
870 Kristian Kvilekval <kris@cs.ucsb.edu>.
872 2006-04-01 Stepan Kasal <kasal@ucw.cz>
874 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
875 switch all of them on and of when necessary. Fixes the bug when
876 m4sugar macros (e.g., m4_define) were expanded after the first
877 automatic update (e.g., after AC_PREREQ or AC_INIT).
879 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

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

927 checked for existence, so we don't barf over a nonexisting
928 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
930 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
932 * bin/autoupdate.in: Fix some typos.

1425 (Particular Programs): Likewise.
1426 (Coding Style): y is like s with respect to / and ,.
1427 (Limitations of Usual Tools): Document the weird restrictions
1428 that Posix has about { }. Use better quoting.

1451 2005-12-31 Stepan Kasal <kasal@ucw.cz>
1453 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;

1492 CONFIG_SHELL in the environment of the configure rerun.
1493 * doc/autoconf.texi (Here-Documents, config.status Invocation):

1516 Factor functionality to..
1517 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
1518 `AC_SUBST($1)' in the public version.
1519 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
1520 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
1521 ac_pt_* variables.

1543 2005-10-24 Stepan Kasal <kasal@ucw.cz>
1545 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
1546 conftest.o, to see whether the compiler really obeys; rm the object
1547 file before and after the test and register it with ac_clean_files.
1548 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
1550 2005-10-21 Stepan Kasal <kasal@ucw.cz>

1570 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
1571 AC_LANG_PROGRAM, fixing a typo. Don't give details about
1572 the inner workings of AC_LANG_FUNC_LINK_TRY.
1573 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1574 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1575 by the function rather than ignoring it.
1576 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1577 comparing its address. Intel's interprocedural optimization was
1578 outsmarting the old heuristic. Problem reported by
1579 Mikulas Patocka.
1581 2005-10-19 Stepan Kasal <kasal@ucw.cz>
1583 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

1590 2005-10-04 Stepan Kasal <kasal@ucw.cz>
1592 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
1593 before removing it (chmod -R u+rwx); there are three instances of this.
1595 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1596 Stepan Kasal <kasal@ucw.cz>
1598 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1599 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1600 make its content writable before removing it. Remove an errorneous
1601 comment from the end, where the logs of the failed tests are copied
1602 to the main log file.
1604 2005-09-27 Stepan Kasal <kasal@ucw.cz>
1606 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
1607 in case the computer is too quick. Double quote the configure.ac
1608 snippets.
1610 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
1611 problems if the testsuite were running too fast.
1613 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1615 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1616 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1617 (which belong to Xt, not X itself). See Debian bug 327655.
1618 * NEWS: Mention this.
1620 2005-09-07 Stepan Kasal <kasal@ucw.cz>
1622 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
1624 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
1626 * config/move-if-change: Don't output "$2 is unchanged";
1627 suggested by Ben Elliston. Handle weird characters correctly.
1629 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1631 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1632 calls, so that the final expansion of this macro is shorter.
1633 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1634 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1635 the cleanup there. Use AS_VAR_* macros, to be more general.
1636 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1638 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1640 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
1642 2005-09-01 Stepan Kasal <kasal@ucw.cz>
1644 * doc/autoconf.texi (Configuration Headers): Add an index entry
1645 for AH_HEADER.
1647 2005-08-26 Pavel Roskin <proski@gnu.org>
1649 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
1650 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
1651 running xmkmf.
1653 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1655 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1656 The previous patch didn't work, so try a better one.
1658 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1660 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1661 in the example. Reported by Bruno Haible.
1662 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1663 "if $undefined_var;" succeeds with my shell.
1665 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1666 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1667 but change the m4_divert_text to m4_divert_once.
1669 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1671 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1672 Work around bug in Solaris /usr/xpg4/bin/awk.
1673 The bug is present in at least Solaris 8 through 10.
1675 2005-08-24 Stepan Kasal <kasal@ucw.cz>
1677 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
1678 some evil values and relying on the fact that $* concatenates the
1679 parameters by the first character from IFS.
1681 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1682 Stepan Kasal <kasal@ucw.cz>
1684 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
1685 first header appears, define AH_HEADER.
1686 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1687 Update limitations about when to call AC_CONFIG_HEADERS.
1688 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1689 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1690 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1691 ``Configuration Actions''; fix their index entries.
1693 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1694 options correctly. Process N-M as M-N if M is smaller than N.
1695 Process ranges correctly so that N-N will run only N.
1696 Sort and uniquify the tests that will be run. If there is more
1697 than one test, reinsert the banners for the tests.
1698 * tests/autotest.at (Keywords): Unmark XFAIL.
1700 2005-08-23 Stepan Kasal <kasal@ucw.cz>
1702 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
1703 before passing the macro name to AH_TEMPLATE.
1705 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1706 now opens log after option processing; in particular, --version
1707 and --help do not touch config.log.
1709 * Makefile.maint: Revert the change from 2005-08-12.
1711 2005-08-22 Stepan Kasal <kasal@ucw.cz>
1713 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
1714 common code to...
1715 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
1717 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1719 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
1720 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
1721 Language cleanup.
1723 * doc/autoconf.texi (Defining Symbols, Changed Results):
1724 Prepend to LIBS, not append, in examples.
1726 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1728 When building in place, set srcdir="."; suggested by Tim Van Holder.
1730 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1731 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1732 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1733 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
1734 does not mean "no --srcdir option".
1736 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1738 * tests/autoscan.at (autoscan): New file.
1739 * tests/suite.at: Use it.
1740 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
1741 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
1743 * tests/autotest.at (Keywords): Test keywords combinations.
1745 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1747 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1748 add "2>&1"; gzip 1.2.4 prints help on stderr.
1750 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1752 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1753 was pushdef'ed twice while popped only once. Push it only once.
1754 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
1756 2005-07-26 Stepan Kasal <kasal@ucw.cz>
1758 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
1759 prefixed by mere "===", not "configure: === ".
1761 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
1763 * Makefile.maint: Update from Bison.
1765 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
1766 "<tab>" in comment, so that the point is understandable.
1768 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1770 Rewrite substantial part of lib/autoconf/status.m4.
1771 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1772 and CONFIG_COMMANDS are not processed in four separate loops.
1773 Instead, there is one main loop. This alows that the common code
1774 is expanded only once, thus config.status (and configure) is smaller.
1776 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1777 the AC_LIST_FILES and cousins macros are no longer used.
1779 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1780 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1781 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1782 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1783 contain the initialization, nor the for loop, nor the associated
1784 commands; all these go to ...
1785 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1786 _AC_OUTPUT_CONFIG_STATUS.
1787 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1788 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1789 (_AC_OUTPUT_FILE): The creation of the sed script ...
1790 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1791 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1792 _AC_OUTPUT_MAIN_LOOP.
1793 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1794 _AC_CONFIG_COMMANDS): Use ...
1795 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1796 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1797 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1798 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1799 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1800 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1801 ... new macros.
1802 (_AC_CONFIG_UNIQUE): Update.
1803 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1804 Replaced by this ...
1805 (_AC_LIST_TAGS): ... new common macro.
1806 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1807 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1808 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1809 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1810 this didn't belong to the `config commands' section.
1811 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1812 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1813 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1814 to the `config commands' section either.
1815 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1816 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1818 ... and many changes to the comments nearby.
1820 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1821 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1822 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1823 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1824 (#define header templates): The comment at the top of the generated
1825 header now includes the name(s) of the source file(s).
1827 Several unrelated small changes:
1829 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1830 parameter to AC_DIAGNOSE.
1831 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1832 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1833 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1834 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1835 with AU::AC_OUTPUT.
1836 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
1837 in AC_OUTPUT doesn't double-quote it either.
1838 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
1839 parameters.
1841 2005-07-10 Stepan Kasal <kasal@ucw.cz>
1843 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
1844 versions of Portland Group compiler produce single- and double-quoted
1845 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
1846 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
1848 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1850 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1851 This is a corrected version of yesterday's patch.
1853 2005-07-07 Stepan Kasal <kasal@ucw.cz>
1855 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
1856 path, too; insert a "===" to emphasize the line.
1858 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
1859 ac_cv_build_alias to ac_build_alias.
1860 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
1862 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
1863 change eliminates it. Problem reported by Alexandre Duret-Lutz.
1864 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...

1878 to INIT_PREPARE.
1879 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign

1933 configure_input, top_builddir, srcdir, etc.
1934 * lib/autotest/general.m4 (AT_INIT): Likewise, for
1935 PATH_SEPARATOR in AUTOTEST_PATH.

1945 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2004 addition.
2006 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2029 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2030 Don't worry about backslashes in srcdir; it can't happen now.

2059 (Special Shell Variables): Fix sed code this in the example.
2060 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2061 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2063 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

2074 * doc/autoconf.texi:
2075 Don't mention Solaris versions so much, if a
2076 problem is common to all extant versions of Solaris. Say "SunOS
2077 4" instead of "SunOS" for SunOS 4.
2078 (awk): Mention more of the limitations of traditional Awk.

2112 quotes and backslashes. Patch from Derek Price.

2121 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2122 -u, since it outputs chatter if the input files are the same.
2123 Problem reported by Ralf Menzel.
2125 2005-06-08 Derek Price <derek@ximbiot.com>
2127 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2128 renaming them since they are about to be redefined anyhow.
2130 2005-06-08 Derek Price <derek@ximbiot.com>
2132 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2133 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2134 Move m4_undefine to alphabetical order.
2136 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

2139 * doc/autoconf.texi (Introduction): Likewise.
2140 Reword to avoid some formatting glitches.
2141 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

2143 Redo example output tp match current CVS snapshot.
2144 Use @example.org in email addresses when the examples
2145 might get inadvertently cut-and-pasted into user code.
2146 Remove example of autom4te usage that doesn't seem to work now.
2147 Use modern AC_INIT (except when the example is meant to be
2148 shown with Autoconf 2.13).
2149 Update ksh info for Solaris 9 and later.
2150 KB -> kB.

2162 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2163 Tru64 ksh pattern matching bug. Reported against Libtool by
2164 Albert Chin <libtool@mlists.thewrittenword.com> and
2165 Nicolas Joly <njoly@pasteur.fr>.
2167 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2169 m4_cdr of one-member list was [[]] (one-member list containing an
2170 empty string) instead of [] (an empty list. Callers were skewed to
2171 match this misbehaviour. As a consequence of this:
2172 - m4_foreach([x], [], [foo]) expanded to `foo', while
2173 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2174 This bug has been fixed:
2176 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2177 expand to an empty string; print error msg if called without
2178 an argument list.
2179 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2180 misbehaviour; handle [] and [[]] correctly.

2190 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2191 swallow records with more than 99 fields.
2192 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2193 parse the long line.
2195 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2197 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

2210 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2211 (DISTCLEANFILES): Remove $(check_SCRIPTS).

2232 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2233 now contain newlines, and substituted files must be referenced on
2234 a line alone; the sed scripts to substitute them are now very
2235 different.

2237 commands can be put in a sed script portably.
2238 * doc/autoconf.texi (Setting Output Variables): Document above

2251 classes in shell scripts. The test was too brittle.
2253 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2255 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

2287 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2288 (ac_top_builddir): ... this ...
2289 (ac_top_build_prefix): ... to this; the old name is also kept, for
2290 backward compatibility.
2291 (ac_top_builddir_sub): New variable, without the trailing slash,
2292 always nonempty.
2293 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

2311 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2313 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2314 ``cat <<_ACEOF'' commands to one.

2317 ``echo|sed.''
2318 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2319 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2320 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2321 a range.
2322 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2323 the wrong patterns between ``case'' and ``esac.'' The previous
2324 code had false positives.
2326 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2328 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2329 as on 2005-05-02.
2330 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2331 Mention LIBOBJDIR.

2371 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2373 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2374 check.
2375 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2376 enough arguments, similarly as in m4_bpatsubsts.
2378 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2380 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2381 of absolute paths.
2383 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2385 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2386 for absolute directory names in one loop.
2387 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2388 abbreviations of --version and --debug.
2390 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2392 * doc/autoconf.texi (Autoconf Language): Be more precise about
2393 quoting rules. Problems noted by Stepan Kasal.
2394 Also, throughout this document, be more careful about white space.
2395 "blank", "white space", and "space" all have different meanings
2396 and we should be careful to say what we mean.
2398 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2400 Fix C++ related problems reported by Werner Lemberg.
2401 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2402 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2403 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2404 avoid problems with C++ and throw.
2405 * tests/compile.at: .cpp, not .cc.
2407 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2409 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2411 * doc/autoconf.texi (Generic Functions): Typos.
2413 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2415 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2416 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2417 set by latest automake.
2419 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2421 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2422 outputs 0 on GNU/Linux these days.
2424 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2426 * doc/autoconf.texi (Autoconf Language): Add more description
2427 about quoting heuristics.
2428 (Limitations of Builtins): Describe "set -" problems.
2430 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2432 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2433 not newline.
2435 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2436 by AC_DEFINE; it was a mistake.
2437 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2439 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2441 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2443 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2445 * doc/autoconf.texi (External Software): Quadrigraphs are not
2446 processed correctly in AS_HELP_STRING; avoid this in the examples.
2447 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2448 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2449 comment and reduce m4_default([foo], []) to [foo].
2450 (m4_strip): Update the explanation.
2452 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2454 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2455 Remove core.conftest.* too; it's generated by Tru64 5.1.
2456 Problem reported by Jennis Pruett.
2457 * lib/autoconf/functions.m4
2458 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2459 Don't bother to remove core files; AC_RUN_IFELSE should do that
2460 for you.
2462 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2464 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2466 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

2471 2005-04-15 Stepan Kasal <kasal@ucw.cz>
2473 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
2474 the comment.
2476 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
2478 * doc/autoconf.texi (External Software, Package Options): Add
2479 examples showing how to implement --with-* and --enable-* options.
2481 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2483 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2484 as well as configure.in. Problem reported by Gregorio Guidi.
2486 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2488 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2489 pattern for alloca snippet.
2491 2005-04-04 Stepan Kasal <kasal@ucw.cz>
2493 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

2499 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2501 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2502 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2504 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2506 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2507 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2508 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2509 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2510 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2512 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2514 * NEWS: The configure command now warns you if you attempt to use
2515 a directory whose name contains a special character like space,
2516 newline, or "\".
2517 * doc/autoconf.texi (Installation Directory Variables): Allow
2518 "," in file names. Do not use \@; it's not a portable regexp.
2519 * bin/Makefile.am (edit): Likewise.
2520 * lib/Makefile.am (edit): Likewise.
2521 * tests/Makefile.am (edit): Likewise.
2522 * tests/semantics.at: Likewise.
2523 * tests/torture.at: Likewise.
2524 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2525 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2526 * doc/autoconf.texi (File System Conventions): Warn about
2527 unportable file names.
2528 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2529 (AC_INIT): Use it.
2530 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2531 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2532 ac_pwd, and quote srcdir.
2533 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2535 * doc/autoconf.texi: Fix some systematic formatting problems.
2536 ".)" needs a following @: if not at the end of a sentence, and
2537 similarly for "!)". "etc." should be preceded by a comma.
2538 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2540 2005-03-22 Bruno Haible <bruno@clisp.org>
2542 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2543 argument is often called 'build-aux'.
2545 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2547 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2548 macro AC_TRY_LINK is obsolete.
2549 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2550 `AC_CONFIG_FILES'.
2552 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2554 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2555 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2556 from a Common Lisp's `cl'.
2557 (AC_PROG_CXX): Behave according to the documentation: don't
2558 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2559 make the variable CCC precious; use `cl.exe', not `cl'.
2561 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2562 Alexandre Duret-Lutz <adl@gnu.org>
2564 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2565 /dev/null, as "configure" shouldn't read stdin, and this insulates
2566 us from problems (e.g., when testing for "cl"). Also, do this
2567 redirection before invoking "hostname" or "uname", and keep the
2568 original input stream available via...
2569 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2570 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2571 bother with "</dev/null" since it's now done at the top of
2572 'configure'.
2573 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2574 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2575 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2576 * doc/autoconf.texi (File Descriptor Macros): New section.
2577 (Printing Messages): Mention it.
2578 * tests/base.at (Input/Output): New test.
2580 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2582 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2583 newline if neither \c nor -n work, as that would output two
2584 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2586 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2588 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2589 This causes that any required macros inside will get before the if.
2590 * doc/autoconf.texi (autom4te.cache): A typo.
2592 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2594 Undo previous change, except keep the change to
2595 lib/autoconf/programs.m4 that replaced grep with shell
2596 pattern-matching. This is because net-snmp configure reads stdin.
2597 Reported by Noah Misch.
2599 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2601 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2602 from /dev/null, as "configure" shouldn't read stdin, and this
2603 insulates us from problems (e.g., when testing for "cl").
2604 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2605 before invoking "hostname" or "uname".
2606 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2607 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2608 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2609 "</dev/null" since it's now done at the top of 'configure'.
2610 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2611 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2612 Also, replace grep with shell pattern-matching, to save a process.
2614 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2616 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2617 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2618 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2619 compiler.
2621 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2623 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2624 grep -q isn't portable. Improve grep -s explanation.
2625 Problem reported by Dan Manthey.
2627 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2629 * doc/autoconf.texi (Special Shell Variables): Clarify
2630 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2632 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2634 * doc/autoconf.texi: Use @acronym for DJGPP.
2635 Fix some @code's that should have been @env's, and vice versa.
2636 Sort environment variable names.
2637 Mention that shells no longer inherit IFS.
2638 Don't recommend PATH_SEPARATOR=';' so strongly.
2639 Mention that $RANDOM might expand to the empty string.
2640 "symlink" and "soft link" -> "symbolic link".
2641 Improve mktemp description (reported by Bruno Haible).
2643 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2645 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2646 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2647 Likewise.
2648 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2649 Likewise.
2651 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2653 * NEWS: Mention AT_COPYRIGHT.
2655 * tests/local.at (AT_CMP): Use diff directly on input files rather
2656 than copying them.
2658 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
2659 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
2661 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2662 and Paul Eggert <eggert@cs.ucla.edu>
2664 * tests/autotest.at (Empty test suite): New test.
2665 * tests/torture.at (Substitute and define special characters)
2666 (Substitute a 2000-byte string, Define to a 2000-byte string)
2667 (Substitute a newline, Define a newline): New tests.
2669 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2671 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
2672 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
2673 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
2674 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
2675 (Standard regular expressions): New test.
2676 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
2677 excess test name quoting.
2678 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
2679 CPPFLAGS to `configure' instead of setting it in `configure'.
2681 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
2682 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
2683 on some platforms.
2685 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
2686 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
2688 * tests/local.at (AT_CMP): New macro.
2689 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
2690 (AC_SAVE_STATE): Move environment grep...
2691 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
2692 (AT_CONFIG_CMP): New macro.
2693 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
2694 * tests/c.at (Extensions): Do not exit early.
2695 * tests/atlocal.in: Inherit $GREP.
2697 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
2698 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
2700 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
2701 (AC_COPYRIGHT): Factor header comment portion out and move into...
2702 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
2703 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
2704 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
2705 --version output.
2706 * tests/local.at: Add Autoconf test suite copyright notice.
2707 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
2709 2005-02-04 Bruno Haible <bruno@clisp.org>
2710 and Paul Eggert <eggert@cs.ucla.edu>
2712 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
2714 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
2716 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
2717 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2719 Try not to generated lines of unlimited length, as POSIX places a
2720 2047-byte limit on line length of portable text files.
2721 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2722 Use newline as a separator, not space.
2723 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
2724 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
2725 space.
2727 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2729 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
2730 as_func_*. Add test to check whether positional parameters
2731 are restored after function return.
2733 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
2735 * doc/autoconf.texi (Special Shell Variables): Mention _,
2736 BIN_SH, DUALCASE. Say that variables other than "status" are safe
2737 if they contain a lower-case letter. The DUALCASE problem was
2738 reported by Ralf Wildenhues.
2740 * bin/autoconf.as: Don't exit with status 0 after write failure
2741 with --help or --version.
2742 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
2743 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
2745 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2747 * doc/autoconf.texi (Limitations of Usual Tools):
2748 Unicos 9 sed limitations.

2780 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2781 Update the long comment explaining it.
2783 m4_require no longer writes an ``is required by'' line to the
2784 execution stack. It contains only one bit of non-redundant
2785 information: that the macro was required, not called. And even
2786 this bit is useless in most situations: have you ever met a macro
2787 which both calls and requires the same macro?
2789 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2790 (_m4_defun_pro_outer): ... only via this macro, for the outermost

2797 (_m4_require_call): Use it.
2798 * tests/m4sugar.at (m4_require): Expect output without the
2799 ``is required by'' messages.
2801 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2803 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2804 rather than x for expr.
2806 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2807 this is safe.
2808 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

2822 support.
2823 * bin/autoheader.in: Pass $force to update_file so that
2824 config.h.in is always recreated when --force.

2835 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2837 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2838 Warn about newline stripping in `` and $(). Update Solaris
2839 version to 9.

2843 stripping.
2845 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2865 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
2867 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2869 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

2893 otherwise.
2894 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
2895 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
2896 stored in _m4_divert_diversion or _m4_divert_dump.
2897 (m4_divert_pop): When the parameter is given, compare the symbolic
2898 name with the last diversion pushed on the stack. Previously, the
2899 current diversion was compared with the numeric value of the
2900 diversion given as the parameter.
2901 (m4_require): If the macro hasn't been expanded yet, call ...
2902 (_m4_require_call): this new macro.

2935 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

2937 not essential. Reported by Magnus Therning.
2938 * tests/torture.at (autoreconf.): New banner.
2939 (autoreconf and non-AC configure): Rename to `Non-Autoconf
2940 AC_CONFIG_SUBDIRS'.

2988 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
2989 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

3116 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

3204 value of the #define--default to 1, iff the macro was called
3205 with exactly one parameter.
3207 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3209 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3210 "char c = '\200';" rather than "char c = 0x80;" as the
3211 latter doesn't conform to the strict C standard due to
3212 overflow on signed char hosts.
3214 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3215 to -qlanglvl=ansi. We don't want to disable extensions.
3217 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
3219 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
3220 (Using Autotest, testsuite Scripts, Writing testsuite.at):
3221 Reword slightly to avoid some English-language problems noted

3272 simplify the examples and improve their quoting.
3274 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3276 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3277 the $1_found variable, don't test whether the file is executable;
3278 Both things are checked ...
3279 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3280 the former ``test -f''.
3281 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
3283 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

3286 use cp -R instead.
3288 2004-11-10 Derek R. Price <derek@ximbiot.com>
3290 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
3291 limitations. Reorder paragraphs for clarity.
3293 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3295 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
3296 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
3297 variants", "Unix", and some related minor wording fixups.
3299 (Shellology, Special Shell Variables): Document that the Zsh
3300 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

3314 * doc/autoconf.texi (auindex): New macro.
3315 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3316 Problem reported by Stepan Kasal.
3318 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3320 Fix problems reported by Andreas Buening in:
3321 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3322 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3323 in test makefile.
3324 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3325 readable; it's not true in OS/2-emx.
3327 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3329 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3330 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3331 (trivial change). Problem and patch reported by Andrew Church in:
3332 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3334 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

3339 Also, fix some minor spacing and punctuation bugs.
3341 2004-09-02 Akim Demaille <akim@epita.fr>
3343 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

3357 Version 2.59b.
3359 * README: Add advice about m4 1.4.2.
3361 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3362 texinfo.tex for now (done by hand now).
3363 * Makefile.maint (wget_files, cvs_files):
3364 Remove ansi2knr.c; nobody uses it.
3365 (ansi2knr.c-url_prefix): Remove.
3366 (cvs-update): Fix test for failure. I don't know why it ever
3367 worked...
3369 * doc/autoconf.texi: Update URLs, some of which went stale.
3370 Use @uref rather than @href.
3372 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3373 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3375 * config/config.guess, config/config.sub, config/elisp-comp,
3376 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3377 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3379 * NEWS, TODO, configure.ac, bin/autoscan.in,
3380 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3381 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3385 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3386 tests/tools.at, tests/torture.at:
3387 Use "file name" rather than "filename" or "path",
3388 to be consistent with the terminology of the GNU coding standards.
3390 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3392 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3393 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3394 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3395 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3397 More fixes to support spaces in the name of the build directory.
3398 This isn't a complete fix but it's an improvement.
3400 * bin/autoconf.as (autom4te_options): New var.
3401 Use it instead of appending to AUTOM4TE, so that we can allow
3402 spaces in the build directory's absolute name.
3403 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3404 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3405 AT_CHECK_NOESCAPE): Likewise.
3406 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3407 main program): Likewise.
3409 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3411 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
3412 From Ralf Corsepius in:

3415 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3417 * doc/autoconf.texi (Function Portability): Document isinf and
3418 and isnan. From a suggestion by Kevin Ryde.
3420 * lib/Autom4te/General.pm (END): Return correct exit status even
3421 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3423 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3425 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3426 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3427 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3429 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3431 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3432 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3433 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3434 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3435 * lib/autom4te.in (Automake-preselections): Preselect
3436 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3438 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3440 * lib/autom4te.in (Automake-preselections): Preselect
3441 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3442 trace them.
3444 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3446 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3447 Tru64.
3448 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3449 Document problem with "`""`" in pdksh POSIX mode.
3451 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3453 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3454 with pdksh, too. Problem reported by Patrick Welche via
3455 Gary V. Vaughan.
3456 * doc/autoconf.texi (Shellology): Note that set -o posix is
3457 useful for pkdsh, too.
3459 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3461 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3462 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3463 Don't fail if ENV or BASH_ENV is readonly.
3464 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3465 etc. are read only. Problem reported by Ludovic Courtes.
3467 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3469 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3470 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3471 (trivial change)
3473 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3475 * doc/autoconf.texi (File System Conventions): Warn about
3476 names like "aux". Problem reported by Eric Blake.
3478 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3479 by zero instead of array size, so that we can use any arithmetic
3480 constant expression (instead of requiring an integer constant
3481 expression). This allows us to test expressions like DBL_MAX <
3482 LDBL_MAX, which didn't conform to the C standard using the old
3483 method.
3484 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3485 now that we can do floating-point tests at compile time.
3487 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3489 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3490 and LDBL_EPSILON, as the resulting expression isn't an
3491 integer constant expression and violates the C standard.
3492 Problem reported by Nelson H. F. Beebe. Also, check
3493 for "L" suffix, and check that long double doesn't have
3494 worse range or precision than double, that mixed-mode
3495 arithmetic doesn't generate a diagnostic, that double
3496 constants fit in long double.
3498 2004-06-03 Kevin Ryde <user42@zip.com.au>
3500 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3501 malloc(0) and realloc(NULL,size).
3503 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3504 Bob Proulx.
3506 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3508 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3509 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3510 by Jim Meyering.
3512 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3514 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3515 can be rewritten using if-then-else. Suggested by Bruno Haible.
3517 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3519 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3520 Problem reported by Stepan Kasal.
3522 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3524 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3525 change). Patch reported by Ralf Wildenhues in
3526 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3528 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3529 function F exists if the compiler and linker let you compile an
3530 expression like (F != 0). Recent versions of GCC optimize away
3531 the reference to F in that case, since every function address must
3532 be nonzero, so the link succeeds even if F does not exist.
3533 Problem reported by Manu in
3534 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3536 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3537 "Unix". Many uses changed.
3538 (Limitations of Builtins): Explain better why the ! command isn't
3539 portable.
3541 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3543 * lib/autom4te.in (Automake-preselections): Preselect
3544 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3546 2004-05-19 Kevin Ryde <user42@zip.com.au>
3548 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3549 referencing AC_FUNC_STRERROR_R.
3551 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3552 note pessimistic assumption when cross compiling.
3554 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3556 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3557 (until 2004) invoked subcommands with sh -e, contra POSIX.
3558 Reported by Kevin Ryde.
3560 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3562 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3563 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3564 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3565 `test -f " /usr/bin/grep"', which _always_ failed.
3566 (AC_PROG_SED): Ditto bogus PATH fix.
3567 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3568 requires that grep correctly supports _multiple_ `-e' options, rather
3569 than stating only that grep should accept `-e'.
3571 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3573 Port to C99, which requires that 'exit' be declared.
3575 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3576 to ensure that stdlib.h is included.
3577 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3578 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3579 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3580 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3581 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3582 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3583 when using 'exit' in a test; C99 requires that 'exit' be declared.
3585 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3587 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3588 now prefers 'grep' implementations that accept -e.
3589 (Limitations of Usual Tools): Describe problems of traditional
3590 egrep and fgrep with long input lines, and of traditional grep
3591 with -e.
3592 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3593 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3594 All callers changed. Append /usr/xpg4/bin to the PATH, for
3595 Solaris.
3596 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3597 the user with complaints about multiple -e options.
3598 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3599 Define it with AC_PROG_GREP.
3600 * configure.ac (AC_PROG_GREP): Add.
3601 * lib/freeze.mk (GREP): New macro.
3603 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3605 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3606 a possible candidate only after all others fail, rather than
3607 consulting it first. This improves backward compatibility by
3608 better reflecting the way shell selection occurred in previous
3609 versions of Autoconf, and should help to avoid triggering latent
3610 problems in other packages, such as the one in Automake where zsh
3611 is not handled robustly:
3612 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3613 Although it is not Autoconf's responsibility to work around
3614 problems in Automake, it nevertheless makes sense to avoid
3615 introducing unnecessary incompatibilites.
3617 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3618 Gary V. Vaughan <gary@gnu.org>
3620 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3621 how deeply nested we are when a suitable tool is found, set the
3622 ac_path_TOOL_found flag.
3623 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3624 nested we are in this macro. Break out of all 3 nested loops if
3625 ac_path_TOOL_found is set.
3627 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3629 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3630 of the _AS_PATH_WALK loop too if GNU flavor is found.
3632 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3634 * doc/autoconf.texi (Limitations of Make): Update documentation
3635 for `$<'. New entry `Long lines', based on a report from Simon
3636 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3637 paragraph about DJGPP, based on a mail from Richard Dawe.
3639 2004-04-20 Paul Eggert <eggert@twinsun.com>
3641 * tests/c.at (C keywords): Don't assume that GCC supports
3642 "restrict" and "inline", as sufficiently-old GCC versions do not
3643 (also, GCC configured to be in pedantic C89 mode does not).
3644 Problem reported by Sumit Pandya in:
3645 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3647 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3648 consider -g to work if it generates warnings when plain compiles
3649 don't. Problem reported by Braden McDaniel in:
3650 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3652 * doc/autoconf.texi (Slashes): New section, to document a problem
3653 reported by Jim Meyering in:
3654 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3656 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential

3661 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3663 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3664 best tool so far counter rely on the tool path variable name to
3665 avoid checks for one tool being affected by the results of running
3666 the length check on a previous tool.
3668 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3669 match expression argument, as different greps have different
3670 regular expression flavours.
3671 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3672 literals.
3673 (AC_PROG_EGREP): Pass 'EGREP$'.
3674 (AC_PROG_GREP): Pass 'GREP$'.
3676 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3678 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3679 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

3683 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3684 Types, Specific Compiler Characteristics, System Services,
3685 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3686 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3687 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3688 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
3689 Likewise.
3690 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
3691 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,

3699 2004-03-28 Paul Eggert <eggert@twinsun.com>
3701 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3702 now defines HAVE_DECL_TZNAME if it is declared, when
3703 HAVE_STRUCT_TM_TM_ZONE is not defined.
3704 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3705 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3706 for HAVE_TZNAME.
3708 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3710 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

3718 H. F. Beebe for the bug report.
3720 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3722 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3723 quoted -cmdline argument in Portland Group compiler (bug
3724 reported by Jeffrey J. Barteet).
3726 2004-03-25 Kevin Ryde <user42@zip.com.au>
3728 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
3729 (Run Time): ... here, where it's now mentioned.

3750 AC_CHECK_TOOLS.
3751 (Specifying Names): Document the reason for these future
3752 behavioral changes.
3753 * tests/mktests.sh: Do not generate tests for the
3754 new macros.
3755 * NEWS: Document these changes.
3757 * doc/autoconf.texi: Avoid macros with unbraced arguments,
3758 they make TeX hang up.
3760 2004-03-15 Paul Eggert <eggert@bogus.example.com>
3762 * NEWS: New macro AC_CHECK_ALIGNOF.
3763 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3764 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3765 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3766 vowel.
3767 (AC_CHECK_ALIGNOF): New macro.
3768 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

3774 * bin/Makefile.am (edit): Don't use $< in a context where
3775 POSIX doesn't require support for it. Use $@.in instead.
3776 Problem reported by Anthony N. Frasso in
3777 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3778 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3780 2004-02-23 Gary V. Vaughan <gary@gnu.org>
3782 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
3783 from the next generation of Libtool.
3784 * lib/autom4te.in (Autoreconf-preselections): Ditto.
3786 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3788 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
3789 is not always thread-safe. Report from Nathanael Nerode.
3791 2004-02-18 Paul Eggert <eggert@twinsun.com>
3793 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3794 problem on QNX reported by Stephen Rasku in
3795 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3797 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
3798 $(m4sh_m4f_dependencies); this removes a FIXME.
3799 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
3800 (MAINTAINERCLEANFILES): Split into pieces,
3801 one per related section. Add $(srcdir)/wrapper.in.
3803 2004-02-09 Paul Eggert <eggert@twinsun.com>
3805 * doc/autoconf.texi (Setting Output Variables): Emphasize that
3806 AC_SUBST provides no portable way to escape literal newlines.
3808 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3809 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3810 Darwin uses -lcrt2.o and there's little point to cataloging all
3811 the system variants. Partial fix reported by Andreas Waechter in:
3812 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
3813 for bug reported by Nelson H. F. Beebe in:

3826 refer to the correct file.
3827 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
3828 the behavior of the third argument.
3829 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
3830 correctly the behavior of the third argument. Document
3831 what the three macros that AU_DEFUN defines do. Fix
3832 warning message when the third argument includes $0
3833 (reported by Alexandre Duret-Lutz).
3835 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3836 Eric Sunshine <sunshine@sunshineco.com>
3837 Paul Eggert <eggert@twinsun.com>
3839 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
3840 (AS_INIT): Output shell initialization there. Removed optional
3841 parameter. Expand _AS_SHELL_FN_SPY.
3842 (AS_INIT_WITH_SHELL_FN): Removed.
3843 (_AS_SHELL_FN_SPY): New macro.
3844 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3845 macros.
3846 (AS_SHELL_SANITIZE): Remove loop to find better shell
3847 and documentation for the parameter.
3848 (_AS_DETECT_BETTER_SHELL): Move it here.

3851 (AS_REQUIRE_SHELL_FN): Require shell functions when
3852 it is used.
3853 (_AS_LINENO_WORKS): Put around braces, we do not
3854 trigger the bash bug anymore.
3855 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3856 use AS_INIT_WITH_SHELL_FN.
3857 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3859 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3861 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
3862 * doc/autoconf.texi: Don't say that the third parameter
3863 is broken.
3864 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
3865 (AU_DEFUN): Honor the third parameter, create autoupdate
3866 macros with AU_DEFINE.
3867 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
3868 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
3869 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3870 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
3871 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

3876 * lib/autoconf/status.m4: Remove FIXME.
3877 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
3878 that the macro is not present anymore in the updated
3879 configure.ac.
3880 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
3881 of autoupdate.
3883 2004-01-28 Paul Eggert <eggert@twinsun.com>
3885 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
3886 copyright years.
3887 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
3888 2003 (except 1997) to the list of copyright years. This undoes
3889 the 2003-05-22 change, which removed the older years from the list.
3890 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
3892 2004-01-27 Gary V. Vaughan <gary@gnu.org>
3893 Albert Chin-A-Young <china@thewrittenword.com>

3896 grep or ggrep program in PATH that accepts as long lines as
3897 possible.

3899 AC_PROG_GREP.
3900 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
3901 egrep and fgrep respectively if $GREP -E/-F don't work.
3902 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
3903 _AC_PROG_GREP, and AC_PROG_SED.
3904 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
3905 longest input length accepted by a command.
3906 (AC_PROG_SED): Use it.
3907 * doc/autoconf.texi (Particular Programs): Document the changes.
3908 * NEWS: Updated.
3910 2004-01-27 Paul Eggert <eggert@twinsun.com>
3912 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

3914 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
3915 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3917 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
3918 bin/autoconf.in, config/Makefile.in, config/config.guess,
3919 config/config.sub, config/install-sh, config/mdate-sh,

3931 tests/actypes.at: Regenerate and/or sync with original
3932 sources.
3934 2004-01-26 Paul Eggert <eggert@twinsun.com>
3936 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
3937 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
3938 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
3939 not <inttypes.h>. Problem reported by Tim Mooney in
3940 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
3941 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
3942 Likewise.
3944 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
3945 otherwise "make check" fails because it forbids cmp (I guess
3946 because cmp treats files as binary on DOS-like systems).
3948 * tests/mktests.sh: Update copyright date to 2004, since some tests
3949 have changed in 2004.
3951 2004-01-23 Gary V. Vaughan <gary@gnu.org>
3953 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
3954 non-truncating sed or gsed program in PATH.
3955 * tests/acprograms.at: Add it.
3956 * doc/autoconf.texi (Particular Programs): Document it.
3957 * NEWS: Updated.
3959 2004-01-15 Paul Eggert <eggert@twinsun.com>
3961 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
3962 -std1 disables some useful extensions on Tru64. Problem reported
3963 by N. Lichtmaier in
3964 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
3966 2004-01-14 Paul Eggert <eggert@twinsun.com>
3968 * doc/autoconf.texi (Programming in M4sh): Document that
3969 AS_MKDIR_P succeeds if the destination is a symbolic link
3970 to an existing directory.
3971 (Limitations of Usual Tools): Note that mkdir -p might not
3972 succeed on symlinks to directories.
3974 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
3976 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
3977 * bin/autoheader.in: Grammar fix in message.
3978 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
3979 Test for dir before calling mkdir -p. (trivial changes)
3981 2004-01-13 Eric Blake <ebb9@byu.net>
3983 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
3984 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
3986 2004-01-10 Jim Meyering <jim@meyering.net>
3988 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
3990 2004-01-09 Paul Eggert <eggert@twinsun.com>
3992 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
3993 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
3994 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
3995 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
3996 AC_COMPILE_IFELSE, since we now assume our caller invokes
3997 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
3998 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
3999 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4000 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4002 2004-01-07 Paul Eggert <eggert@twinsun.com>
4004 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4005 `"'...'"`, as it's confusing (and I suspect it may not work on
4006 some platforms). The code was incorrect anyway, as it assumed
4007 that \$ evaluated to itself in that context. Reported by
4008 Alexandre Duret-Lutz.
4010 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4012 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4013 and _LT_AC_TAGCONFIG.
4015 2004-01-06 Paul Eggert <eggert@twinsun.com>
4017 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4018 example, and add more examples. Reported by Eric Sunshine.
4020 2004-01-05 Paul Eggert <eggert@twinsun.com>
4022 * doc/autoconf.texi (Limitations of Usual Tools):
4023 Remove warning against "rm -fr" introduced yesterday; it
4024 was a false alarm.
4026 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4027 autoscan, autoupdate, ifnames): Don't use chmod -w.
4028 * lib/Makefile.am (autom4te.cfg): Likewise.
4029 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4030 "chmod -w".
4032 2004-01-04 Paul Eggert <eggert@twinsun.com>
4033 Paolo Bonzini <bonzini@gnu.org>
4035 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4036 by doing lineno substitution only on lines containing "$LINENO".
4038 2004-01-04 Paul Eggert <eggert@twinsun.com>
4040 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4041 Use "rm -f" to remove conftest.sed, not plain "rm".
4042 Bug reported by David Relson in
4043 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4045 * Makefile.am (autom4te-update):
4046 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4047 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4048 * doc/autoconf.texi (Guidelines): Likewise.
4049 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4055 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4056 srcdir): Likewise.
4057 * doc/autoconf.texi (Limitations of Usual Tools):
4058 Warn against "rm -fr".
4060 2004-01-03 Paul Eggert <eggert@twinsun.com>
4062 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4063 -c -o might not work. From a suggestion by Kevin Ryde.
4064 (C Compiler, Generating Sources, Limitations
4065 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4066 Don't put '-o' after non-options, as POSIX doesn't allow this.
4067 Mention that cc's name might be gcc or c89 or whatever.
4069 2004-01-04 Kevin Ryde <user42@zip.com.au>
4071 * doc/autoconf.texi: Add various further index entries.
4073 2003-12-29 Paul Eggert <eggert@twinsun.com>
4075 * bin/autoreconf.in (autoreconf_current_directory):
4076 Fix typo: mkdir without umask arg.
4078 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4080 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4081 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4082 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4083 explanation clearer.
4085 2003-12-24 Andreas Schwab <schwab@suse.de>
4087 * doc/autoconf.texi (Default Includes): Fix misspelling of
4088 AC_INCLUDES_DEFAULT.
4090 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4092 * configure.ac: Test if sh -n works.
4093 * configure: Regenerate.
4094 * tests/atlocal.in: Store the result here.
4095 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

4134 * config/announce-gen (&print_locations, &print_signatures)
4135 (&sizes): New.
4136 Use them.
4137 No longer rely on Gnus to inline the list of signatures: compute
4138 them on the fly.
4140 2003-11-24 Akim Demaille <akim@epita.fr>
4142 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
4143 override some files.
4144 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
4145 From Debian Autoconf 2.58.
4147 2003-11-24 Akim Demaille <akim@epita.fr>

4185 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4186 than $target since the latter is not usual, add guidelines on when to

4211 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

4346 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
4347 cross test.
4349 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
4351 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
4352 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

4364 Problems reported by Eric Sunshine.
4366 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4368 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4369 -mGLOB_options_string stuff for Intel ifc, which can cause

4375 * doc/autoconf.texi: Document new FC Fortran macros.

4393 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4394 cache variable instead of $G77 to decide whether to include -O2,
4395 since $G77 is specific to Fortran 77.

4399 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

4402 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4404 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4405 arguments so that it can be used with syntax identical to
4406 AC_PROG_F77, and so that we can more easily decide to
4407 remove/deprecate the DIALECT optional argument in the future if it
4408 proves troublesome.
4409 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4410 non-freeform-supporting compilers. Document freeform flags.
4412 2003-10-03 Akim Demaille <akim@epita.fr>
4414 * configure.ac: Look for emacs, not macs.
4415 Reported by Eric Sunshine.
4417 2003-10-03 Akim Demaille <akim@epita.fr>
4419 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
4420 * bin/autoreconf.in (autoreconf_current_directory): Create the

4422 Suggested by Alexandre Duret-Lutz.
4424 2003-10-03 Akim Demaille <akim@epita.fr>
4426 * configure.ac: Quotation and formatting changes.

4448 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
4449 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

4456 (@news_file): this.
4458 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

4461 have been created when invoking the compiler.

4475 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4476 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4477 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4479 2003-09-26 Akim Demaille <akim@epita.fr>
4481 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4482 directory for AC_CONFIG_COMMANDS' first argument exists.
4483 This makes valid the invocation of _AC_SRCPATH that follows.
4484 Reported by Eric Sunshine.
4485 * doc/autoconf.texi (Configuration Commands): Adjust.
4487 2003-09-26 Akim Demaille <akim@epita.fr>
4489 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4490 Reported by Ralf Corsepius.
4492 2003-09-26 Akim Demaille <akim@epita.fr>
4494 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4495 arguments.

4506 2003-09-26 Akim Demaille <akim@epita.fr>
4508 The test suite are sometimes assigning timings incorrectly.
4509 Reported by Henk Krus.
4510 Diagnosed by Nicolas Joly.
4512 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4513 AT_help_all.
4514 Instead of making AT_help a sequence of assignments to grow
4515 $at_help_all, just make AT_help_all be the growing contents of
4516 $at_help_all, and make a single assignment in...
4517 (AT_INIT): here.
4518 (at_times_skip): Flip the meaning and rename as...
4519 (at_times_p): this.
4520 (AT_INIT): When summarizing the test that ran, remove
4521 $at_times_file after use, and check it is present before trying to
4522 use it.

4530 (ifnames): chmod -w.
4531 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4532 executables, not bin/ executables! Otherwise all the magic needed
4533 to find non installed files is turned off. This caused a failure
4534 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4535 as found in its environment (sent by tests/autoreconf): pointing
4536 to bin/autom4te that could not find its files.
4537 * tests/mktests.sh: Force the replacement of generated files, for
4538 the sake of "mv" program that are interactive when overwriting a
4539 -w file.
4540 * config/install-sh: Upgrade from CVS Automake.
4542 2003-09-23 Paul Eggert <eggert@twinsun.com>

4550 Trivial change to support GCC's configuration procedure.
4551 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4552 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4553 about inconsistency if the preprocessor is set to give errors for
4554 any warning.
4555 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4557 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

4573 2003-09-12 Akim Demaille <akim@epita.fr>
4575 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
4576 not asm/types.h.
4578 2003-09-11 Akim Demaille <akim@epita.fr>
4580 * doc/autoconf.texi (Header Portability): linux/random.h.
4581 From Peter Hendrickson.
4583 2003-09-10 Akim Demaille <akim@epita.fr>
4585 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4586 willing to edit the output files.
4588 2003-09-10 Akim Demaille <akim@epita.fr>
4590 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT

4613 2003-09-05 Paul Eggert <eggert@twinsun.com>
4615 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4616 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4618 2003-09-04 Akim Demaille <akim@epita.fr>
4620 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

4633 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4635 Add support for newer Fortran dialects. The F77 interface is
4636 unchanged, and continues to support Fortran 77. New FC macros
4637 correspond to all the old F77 macros, with output variables FC,
4638 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4639 available dialect, but older dialects can be specified. There are
4640 new macros AC_FC_SRCEXT to set the source extension, and
4641 AC_FC_FREEFORM to accept free-form source files.
4643 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4644 New macros.

4671 Document problems with timestamp resolution that 'make', 'cp -p', and
4672 'touch -r' have.
4674 2003-08-27 Akim Demaille <akim@epita.fr>
4676 * tests/m4sugar.at (cross_warning): Make sure to enable the
4677 output, so that we can track spurious m4sugar output.
4678 * tests/local.at: Require 2.57.
4679 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4680 are defaulted by AT_CHECK anyway.
4681 Use AT_CHECK_AUTOM4TE.
4682 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4683 missing dnl.
4685 2003-08-27 Akim Demaille <akim@epita.fr>
4687 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4688 when -Wobsolete is set.

4731 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
4732 * configure.ac: Require Automake 1.7.6.
4734 2003-08-22 Akim Demaille <akim@epita.fr>
4736 Output stack traces in warnings.
4738 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
4739 Replace the former...
4740 (m4_warn): Pass the call stack to _m4_warn.
4741 * bin/autom4te.in: Adjust to output the call stack.
4742 * tests/m4sugar.at (m4@&t@_warn): Adjust.
4744 2003-08-22 Akim Demaille <akim@epita.fr>
4746 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
4747 * bin/autom4te.in: Adjust.
4749 2003-08-21 Akim Demaille <akim@epita.fr>
4751 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
4752 (&verbose): Remove.
4753 (&getopt): Adjust the note and verb channels, depending upon
4754 --verbose.

4756 * bin/autoupdate.in: Adjust.
4757 Use &verb, not &verbose.
4759 2003-08-21 Akim Demaille <akim@epita.fr>
4761 * bin/autoheader.in (&parse_args): Use &parse_warnings and
4762 &parse_WARNINGS.

4764 * bin/autoscan.in: Use Autom4te::ChannelDefs.
4765 * lib/Autom4te/General.pm: Don't export error: you don't own it.
4767 2003-08-21 Akim Demaille <akim@epita.fr>
4769 First stab at preserving warnings between calls to autom4te,
4770 including when the cache is used.
4772 There are still several issues: (i) there are too many runs of m4
4773 (one for include, one for warnings, and some more), (ii) warnings
4774 spreading on several lines are not handled gracefully, (iii) the
4775 code meant to have the call stack display for errors does not work
4776 (its handling should move from m4 to autom4te).
4778 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4779 Use them.
4780 (@preselect): Add m4_warn.
4781 ($exit_status): Remove, use $exit_code.
4782 ($help): Use Autom4te::ChannelDefs::usage.
4783 (&handle_m4): No longer define the m4_warnings.
4784 At each run, extract and report the warnings.
4785 Always cache the result, including if the exit status is on
4786 failure, since if nothing changes, we should result in the same
4787 failure, hence we can use the cache.
4788 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4789 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4790 Remove.
4791 (m4_warn): Redefine as a do-nothing: it is its invocation that
4792 matters, as warnings are now reported via traces.
4793 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4794 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4795 the latter reveals calls to the former.
4797 Adjust the tests.
4799 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4801 2003-08-21 Akim Demaille <akim@epita.fr>
4803 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
4804 Use them.
4806 2003-08-21 Akim Demaille <akim@epita.fr>
4808 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4809 forward order.
4810 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4811 (&parse_warnings): Accept a list of warning requests.
4812 (&usage): Return a string, not a side effect.
4813 (cross): New warning category.
4815 2003-08-21 Akim Demaille <akim@epita.fr>
4817 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4818 (&require_configure_ac): Accept an optional directory argument.
4819 ($configure_ac): Remove.
4820 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4821 (&catfile): Remove.
4822 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4823 * bin/autoscan.in: Adjust.
4825 2003-08-20 Akim Demaille <akim@epita.fr>
4827 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4828 Reported by Alexandre Duret-Lutz.
4830 2003-08-20 Akim Demaille <akim@epita.fr>
4832 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4833 * bin/autom4te: Adjust.
4834 In particular, be Autoconf tools are really silent when properly
4835 working, bind the verbosity of the 'note' channel to $verbose.
4836 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4837 (&xsystem, &contents): Remove, since they are exported by...
4838 * lib/Autom4te/FileUtils.pm: this.
4839 More perldoc.
4840 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4841 * lib/Autom4te/FileUtils.pm: here.
4843 2003-08-20 Akim Demaille <akim@epita.fr>
4845 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
4846 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

4898 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4899 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4900 shorter column three. Add DESCRIPTION to log file content.
4902 2003-08-13 Derek Price <derek@ximbiot.com>
4904 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
4905 output.

4913 2003-08-07 Derek Price <derek@ximbiot.com>
4915 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
4916 (AT_CHECK_NOESCAPE): ...to this new macro.
4918 2003-07-31 Paul Eggert <eggert@twinsun.com>
4920 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
4921 in Bash 2.01. Problem reported by Brian Gough in
4922 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

4932 inside '#ifndef __cplusplus'. Problem reported by
4933 Bob Friesenhahn.
4935 2003-07-06 Bill Clarke <llib@computer.org>
4937 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
4938 'long', not 'int', for benefit of Sun's recent C++ compilers
4939 (trivial change). See:
4940 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
4941 (This really should be 'intptr_t', not 'long', but that would
4942 take more work.)
4944 2003-06-25 Akim Demaille <akim@epita.fr>
4946 * lib/Makefile.am (autom4te.cfg): Make it read only.
4947 Depend on Makefile since it contains substitutions.

4960 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
4961 not all of them. This fixes 1. the fact that when testing
4962 Autoconf there are many many config.log, 2. the incorrect use of
4963 top_srcdir to find config.log.
4964 Don't mix the detailed output of failed test with the summary of
4965 failures. Rather, append detailed log afterwards.
4967 2003-06-23 Akim Demaille <akim@epita.fr>
4969 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

5048 (handle_exec_errors): New function. Work around $! being

5052 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5054 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5055 Do not call `_exit()', simply modify `$?'.

5071 exit 63, so that we (or Automake's "missing") can tell the
5072 difference with a plain failure.
5073 * doc/autoconf.texi (Notices): Adjust.
5075 2003-05-23 Akim Demaille <akim@epita.fr>
5077 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5078 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

5081 2003-05-22 Jim Meyering <jim@meyering.net>
5082 Paul Eggert <eggert@twinsun.com>
5084 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5085 Remove `#include <stdlib.h>' from the list; we should never
5086 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5087 resulting namespace pollution would cause other tests to fail.
5088 Configure scripts run with some older versions of g++ and HP's
5089 aCC would fail due to such an #include. Problems reported by
5090 Matthew Mueller in <http://bugs.debian.org/120704> and by
5091 Keith Bostic in
5092 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5093 In the test, use the test declaration before including <stdlib.h>,
5094 as that's closer to how it'll be used.
5096 2003-05-23 Akim Demaille <akim@epita.fr>
5098 * doc/autoconf.texi (Header Portability): ucred.h.
5099 From Ian Redfern.
5101 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5103 Overhaul Autotest's logging: generate separate log files
5104 in testsuite.dir/NNN/testsuite.log, and append them to
5105 testsuite.log instead of re-running the test verbosely.
5107 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5108 file descriptor, write 0 to at_status_file instead of setting
5109 at_status=0, initialize some new variables (at_status_file,
5110 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5111 to rerun the tests, instead append the at_group_log to the
5112 at_suite_log when a test fails.
5113 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5114 with the AS_MESSAGE_LOG_FD redirected to stdout.
5115 (AT_CLEANUP): save the output status in $at_status_file
5116 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5117 its original place.
5118 (AT_CHECK): since tests are run with a redirected stdout,
5119 and used to be re-run in verbose mode, turn some $at_verbose
5120 into echo, and don't redirect the output of testing stdout
5121 and stderr.
5123 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5124 the name of the debugging directory and information about
5125 its contents.
5127 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5129 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5130 parameter.

5242 and truncate.
5244 2003-05-06 Akim Demaille <akim@epita.fr>
5246 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5247 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5248 by aclocal.m4 is changed it might require the importing of another
5249 m4 extension file, i.e., aclocal must be run.
5251 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5252 (&parse_args): Use --force with aclocal if required and supported.
5253 (&autoreconf_current_directory): Use &run_aclocal.

5260 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5261 argument instead of a file name, so that the request file remains
5262 open during the whole autom4te run.
5263 ($icache_file): New.
5264 (&freeze): Lock the $icache_file.
5266 2003-04-29 Derek Price <derek@ximbiot.com>
5268 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5269 seperator with m4_append_uniq(). It doesn't work.
5270 (AT_CLEANUP): Add `;' to end of at_help_all.
5271 (AT_INIT): Allow --keywords to be specified more than once. When
5272 grepping $at_help_all for keywords, use the field and keyword
5273 seperators to ensure a complete keyword match. Alter at_prev handling
5274 to support the new --keywords behavior.
5276 2003-04-27 Karl Berry <karl@freefriends.org>
5278 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5279 align better with others. I also made some of the individual
5280 entries on one line, for brevity and to make it easier for me to
5281 sort my dir-example file in the Texinfo distribution :).
5283 2003-04-12 Jim Meyering <jim@meyering.net>

5329 which removed the main loop.
5330 Thanks to Akim Demaille.
5332 2003-03-29 Akim Demaille <akim@epita.fr>

5336 From Ilya Zakharevich.
5338 2003-03-29 Akim Demaille <akim@epita.fr>

5348 header causes problems.
5350 2003-03-28 Akim Demaille <akim@epita.fr>
5352 * tests/torture.at (Configuring subdirectories): Require aclocal
5353 1.4, otherwise the test fails, as it does support configure.ac.
5354 This fixes the "test 40 failed" bug reports.

5423 * doc/autoconf.texi (Limitations of Make): Remove the section
5424 about `$<' in inference rules, it was a bogus interpretation of
5425 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5426 Tru64 make in the "target lookup" section.
5427 (Automake): Automake 1.5+ no longer requires special tools to be
5428 present on the developer's host.

5446 ${ac_make}.
5448 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5449 When constructing paths with IFS=:, quote the path. If we're
5450 constructing a DOS-style absolute path, we don't want to split it
5451 on the colon.

5469 to fix a mismatch between example and discussion.
5471 2003-02-24 Kevin Ryde <user42@zip.com.au>
5473 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5474 format starting with "-".
5476 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5478 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5479 is not portable inside Makefile.
5481 2003-02-20 Akim Demaille <akim@epita.fr>
5483 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5484 compiler says yeah, but preproc says nope, compiler is right.
5485 Conversely, prompt the reader to send a bug report to the
5486 maintainers of the package, not of Autoconf.
5488 2003-02-20 Klee Dienes <kdienes@apple.com>
5490 * bin/autoreconf.in (autoreconf_current_directory): Properly

5501 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5502 innocuous variant befor including <limits.h> or <assert.h>. This
5503 works around a bug reported by Albert Chin: HP-UX 11i
5504 (and earlier versions) have a <limits.h> that declares
5505 gettimeofday and many other functions.
5507 2002-12-03 Paul Eggert <eggert@twinsun.com>
5509 Version 2.57.
5511 * NEWS, configure.ac: Update version.
5513 * doc/fdl.texi: Upgrade to FDL version 1.2.
5515 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5516 nontrivially in main's body, so that f's external declaration is
5517 not optimized away in AIX. This should fix the bug reported by
5518 Martin Frydl in
5519 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5521 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5522 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5523 defined, to support freestanding compilers. This should fix the
5524 bug reported by Momchil Velkov in
5525 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5527 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5528 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
5529 obsolete AC_CHECK_TYPE. The missing empty arg was reported
5530 by Simon Josefsson in
5531 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
5533 * Makefile.maint (www-gnu): New macro.
5534 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
5535 the location has moved.
5537 2002-12-02 Martin Frydl <martin@systinet.com>
5539 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5540 \(.*\) match is too long and there is something more to be checked.
5541 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

5559 Update from masters.
5561 2002-11-14 Akim Demaille <akim@epita.fr>
5563 * Makefile.maint: Sync with Bison, i.e.:
5564 (po-check): Scan .l and .y files instead of the
5565 .c and the .h files that they generate. This fixes the bug
5566 reported by Tim Van Holder in:
5567 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5568 Look for N_ as well as for _. Try to avoid matching #define for
5569 N_ and _.
5570 From Paul Eggert.
5572 2002-11-14 Akim Demaille <akim@epita.fr>
5574 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5575 From Paul Eggert and Albert Chin-A-Young.
5577 2002-11-14 Akim Demaille <akim@epita.fr>
5579 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5580 From Paul Eggert and Albert Chin-A-Young.
5582 2002-11-14 Kevin Ryde <user42@zip.com.au>
5584 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5585 than assigning in main, to avoid HP cc +O3 optimizing it away.
5587 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5589 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5590 option. Process --recheck after parsing all options. Pass -q
5591 option to configure on --recheck.
5592 (AC_OUTPUT): Pass -q from configure to config.status.
5593 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5594 arguments to record.
5595 * doc/autoconf.texi (config.status Invocation): Document
5596 config.status -q option.
5598 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
5600 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
5601 Makefile.in if Makefile.am exists.

5623 Reported by Ezra Peisach.
5625 2002-11-05 Akim Demaille <akim@epita.fr>
5627 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5628 Remove.
5629 We _have_ to stop using the old compatibility scheme that tried to
5630 avoid useless backslashes because Libtool 1.4.3 contains a
5631 AC_DEFINE([error_t], [int],
5632 [Define to a type to use for \`error_t' if it is not
5633 otherwise available.])
5634 We _have_ to quote the single quote and backslashes with \. The
5635 old compatibility scheme saw that ` was backslashed, and therefore
5636 did not quote the single quote. Hence before this patch, Autoconf
5637 was not compatible with Libtool.
5639 2002-11-04 Paul Eggert <eggert@twinsun.com>
5641 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

5679 2002-10-31 Akim Demaille <akim@epita.fr>
5681 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5682 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5683 Make variable, not a shell variable.
5684 Suggested by Bruno Haible.
5686 2002-10-31 Akim Demaille <akim@epita.fr>
5688 * bin/autom4te.in (load_configuration): Reject #args out of any
5689 language.
5691 2002-10-31 Akim Demaille <akim@epita.fr>
5693 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

5705 Suggested by Tim van Holder.

5709 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
5710 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5711 Problem reported by Bruno Haible.
5713 2002-10-29 Akim Demaille <akim@epita.fr>
5715 * doc/autoconf.texi (Header Templates): Put also in words what the
5716 pictures says to assist free style readers.
5717 (Customizing autom4te): s/--cache=/--cache /.
5719 2002-10-29 Akim Demaille <akim@epita.fr>

6027 longer required can still cause errors.
6028 Reported by Alexandre Duret-Lutz.
6030 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

6050 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6051 if some file was changed instead of `print'.
6052 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6053 (&parse_args): Remove the dead options.
6054 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
6055 autoheader's quiet mode.
6056 (AT_CHECK_AUTOUPDATE): Likewise.
6057 * tests/tools.at (autoupdate): Adjust.
6058 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6060 2002-10-11 Akim Demaille <akim@epita.fr>
6062 No longer use CPP to check for the existing of headers: use CC to
6063 check for compilability.
6065 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6066 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
6067 (_AC_CHECK_HEADER_NEW): Rename as...
6068 (AC_CHECK_HEADER): this.
6070 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6071 numbers in the Subject suggestion.
6073 2002-10-11 Akim Demaille <akim@epita.fr>
6075 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
6076 Suggest using AC_CHECK_DECLS instead.
6078 2002-10-11 Akim Demaille <akim@epita.fr>
6080 * tests/torture.at (AC_ARG_VAR): Have configure report the value
6081 of `precious'.
6083 2002-10-11 Akim Demaille <akim@epita.fr>
6085 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6086 file name to enable parallel executions.
6087 From Sam Varshavchik.
6089 2002-10-08 Akim Demaille <akim@epita.fr>
6091 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6092 aclocal invocation, as Gettext macros might not be visible to
6093 aclocal.
6094 Instead of blindly running autopoint, scan configure.ac (not the
6095 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6096 Reported by Paul D. Smith.
6098 2002-10-08 Paul Eggert <eggert@twinsun.com>
6100 Work around problems found when POSIXLY_CORRECT=1 is set.
6101 None of this seems to have anything to do with POSIX, really,
6102 but it's how Perl getopt works.
6103 * bin/autom4te.in (parse_args): Configure GetOpt with
6104 "permute", too.
6105 * doc/autoconf.texi (Invoking autom4te):
6106 --warning -> --warnings.
6107 * lib/autom4te.in: --warning -> --warnings.
6109 2002-09-28 Akim Demaille <akim@epita.fr>
6111 * doc/autoconf.texi (autom4te.cache): New section.
6113 2002-09-28 Akim Demaille <akim@epita.fr>
6115 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
6116 (Automake-preselections): Update.
6117 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
6119 2002-09-28 Akim Demaille <akim@epita.fr>
6121 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
6122 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
6123 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
6124 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
6126 2002-09-28 Akim Demaille <akim@epita.fr>
6128 * tests/torture.at (Configuring subdirectories): Be robust to
6129 users who use config.site to require for a cache: in this case,
6130 the two last configure runs, using two different sets of
6131 arguments, trigger a legitimate error.
6133 2002-09-28 Akim Demaille <akim@epita.fr>
6135 * tests/m4sh.at (Functions Support, Functions and return Support):
6136 New.
6138 2002-09-28 Akim Demaille <akim@epita.fr>
6140 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
6141 autoheader are Perl programs.
6142 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
6143 (autom4te): Specify that the sources are in the $srcdir.
6144 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6146 2002-09-28 Akim Demaille <akim@epita.fr>
6148 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
6149 (tm_zone): Move their rules to...
6150 * lib/autoconf/types.m4: here, using AN_ macros.
6151 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6152 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6153 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6154 * lib/autoconf/programs.m4: here.
6155 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
6156 (ETAGS_FOR_AUTOCONF): New.
6157 Use it.
6159 2002-09-28 Akim Demaille <akim@epita.fr>
6161 * lib/autoconf/autoscan.m4: New file.
6162 * lib/autoconf/autoconf.m4: Include it.
6163 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
6164 that were listed in the original autoscan.list.
6165 * lib/autoconf/headers.m4: Similarly with headers.
6166 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6167 (.m4.m4f): Don't pass --prepend-include, since that's done by
6168 tests/autom4te itself.
6169 * lib/autoscan/Makefile.am: Include freeze.mk.
6170 (autoscan.list): New target --this file is no longer a source.
6171 (autoscan.pre): New file.
6173 2002-09-28 Akim Demaille <akim@epita.fr>
6175 * bin/autoscan.in (@kinds): Make them singular.
6176 Adjust all uses.
6177 (&init_tables): When --debug, report the list of rules to ease
6178 tracking changes in autoscan.list.
6179 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6181 2002-09-28 Akim Demaille <akim@epita.fr>
6183 * lib/autoscan/functions, lib/autoscan/headers,
6184 * lib/autoscan/identifiers, lib/autoscan/makevars,
6185 * lib/autoscan/programs: Merge into...
6186 * lib/autoscan/autoscan.list: this.
6187 * bin/autoscan.in (&init_tables): Adjust.
6189 2002-09-28 Akim Demaille <akim@epita.fr>
6191 * lib/autoscan/functions, lib/autoscan/headers,
6192 * lib/autoscan/identifiers, lib/autoscan/makevars,
6193 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6194 `functions' line is now prefixed with `function:'.
6195 * bin/autoscan.in (&init_tables): Adjust.
6197 2002-09-28 Akim Demaille <akim@epita.fr>
6199 From now on, autoscan files must always map a macro name to a
6200 word: there is no `default' macro for autoscan.
6202 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6203 all.
6204 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6205 explicit.
6207 2002-09-28 Akim Demaille <akim@epita.fr>
6209 * bin/autoscan.in (%c_keywords): Remove.
6210 (&used): Keep only track of the words we might be interested in.
6211 (&output_kind): It is no longer needed to look for non active
6212 checks.
6214 2002-09-27 Akim Demaille <akim@epita.fr>
6216 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
6217 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
6218 * lib/autoscan/functions: Adjust.
6219 * doc/autoconf.texi (Particular Functions): Adjust.
6221 2002-09-27 Akim Demaille <akim@epita.fr>
6223 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
6224 from /tmp.
6225 Thanks to Bill Moseley and Paul Eggert.
6226 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6227 the tmpdir must be created.
6228 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6229 dir be in the build tree, instead of $TMPDIR.
6231 2002-09-27 Akim Demaille <akim@epita.fr>
6233 * bin/autoscan.in: Improve the comments.
6234 (&parse_args): Drop obsolete undocumented options.
6235 (&output_kind): Output warnings.
6236 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
6237 (getwd): Trigger a warning.
6239 2002-09-26 Akim Demaille <akim@epita.fr>
6241 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6242 Reported by Ralf Corsepius.
6243 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6245 2002-09-26 Akim Demaille <akim@epita.fr>
6247 Single suffix rules and seperated dependencies are not portable.
6249 * doc/autoconf.texi (Installation Directory Variables): Update.
6250 (Limitations of Make): Some about `Single Suffix Rules and
6251 Separated Dependencies'.
6252 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6253 (ifnames, autoscan, autom4te): Un-factor into several rules.
6255 2002-09-25 Paul Eggert <eggert@twinsun.com>
6257 * BUGS (Interoperability bugs): New section. Mention libtool
6258 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6260 2002-09-24 Paul Eggert <eggert@twinsun.com>
6262 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6263 make handles suffix-rules differently from GNU make.
6265 * bin/Makefile.am (SUFFIXES, .in): Remove.
6266 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6267 Move the body of the old .in rule here.
6269 2002-09-16 Akim Demaille <akim@epita.fr>
6271 i960 compilers create `b.out' files by default.
6272 Reported by Ralf Corsepius.
6274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6275 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6277 2002-09-13 Paul Eggert <eggert@twinsun.com>
6279 * doc/autoconf.texi (Particular Headers): Remove obsolete
6280 reference to `struct timezone' in the description of
6281 AC_HEADER_TIME.
6283 2002-09-13 Akim Demaille <akim@epita.fr>
6285 Version 2.54.
6287 * config/config.sub, config/config.guess: Update.
6288 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6289 * Makefile.am: Adjust.
6291 2002-09-13 Akim Demaille <akim@epita.fr>
6293 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6294 reading config.log when the compiler is rejected.
6295 Suggested by Guido Draheim.
6297 2002-09-13 Akim Demaille <akim@epita.fr>
6299 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6300 (chdir_init) might hang when stat'ing mounted directories.
6301 Reported by Vance Shipley.
6303 2002-09-12 Akim Demaille <akim@epita.fr>
6305 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6306 the lists.
6308 2002-09-12 Akim Demaille <akim@epita.fr>
6310 * doc/autoconf.texi (Defining Symbols): Present two different
6311 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6312 difference between 1 argument calls, and 2-3 argument calls.
6314 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6316 * doc/autoconf.texi: Review grammar and punctuation.
6318 2002-09-11 Paul Eggert <eggert@twinsun.com>
6320 * doc/autoconf.texi: Fix minor formatting, spelling, and
6321 grammatical typos.
6322 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6323 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6324 is obsolescent.
6326 2002-09-11 Akim Demaille <akim@epita.fr>
6328 * doc/autoconf.texi (Questions): Rename as...
6329 (FAQ): this.
6330 (Defining Directories): New.
6332 2002-09-09 Akim Demaille <akim@epita.fr>
6334 * doc/autoconf.texi (Making testsuite Scripts): Update.
6335 Suggested by Nishio Futoshi.
6337 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6339 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6340 plain `@' is wanted.
6342 2002-09-09 Akim Demaille <akim@epita.fr>
6344 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6345 `duplicates', since the algorithm was too naive and could keep
6346 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6347 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6348 Reported by Ralf Corsepius.
6349 * tests/torture.at (Configuring subdirectories): Exercise these
6350 cases.
6352 2002-09-09 Akim Demaille <akim@epita.fr>
6354 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6355 looking for a replacement file.
6356 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6357 directory is relative.
6358 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6359 directory definition.
6360 Reported by Andreas Schwab and Jim Meyering.
6362 2002-09-06 Akim Demaille <akim@epita.fr>
6364 * doc/autoconf.texi (Setting Output Variables): Clarify what
6365 precious variables are.
6366 Suggested by Pontus Skoeld.
6368 2002-09-05 Akim Demaille <akim@epita.fr>
6370 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6371 (ifnames, autoscan, autom4te): Since we don't only depend on
6372 configure.ac variables (such as VERSION etc.), but also on prefix
6373 and so forth, depend on Makefile, not configure.ac.
6374 Reported by Alexandre Duret-Lutz.
6375 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6377 2002-09-05 Kevin Ryde <user42@zip.com.au>
6379 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6380 doesn't seem to be confined to ia64, just say "some versions".
6382 2002-09-04 Akim Demaille <akim@epita.fr>
6384 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6385 Automake 1.6c.
6386 * Makefile.am (maintainer-clean-local): Remove.
6387 (MAINTAINERCLEANFILES): Remove COPYING.
6389 2002-09-03 Paul Eggert <eggert@twinsun.com>
6391 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6392 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6393 Brinkmann.
6395 2002-09-03 Akim Demaille <akim@epita.fr>
6397 * configure.ac: Bump to 2.53d.
6398 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6399 as of today, on Automake's team suggestion.
6401 2002-09-03 Akim Demaille <akim@epita.fr>
6403 Version 2.53c.
6405 2002-09-02 Akim Demaille <akim@epita.fr>
6407 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6408 SITE_MACRO_DIR.
6409 * configure.ac: Disable SITE_MACRO_DIR.
6411 2002-09-02 Jim Meyering <meyering@lucent.com>
6413 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6414 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6415 Also, tweak grammar: s/make sure to/be sure to/.
6417 2002-09-02 Paul Eggert <eggert@twinsun.com>
6419 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6420 directory names are generally preferable to physical names.
6422 2002-09-02 Akim Demaille <akim@epita.fr>
6424 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6425 Reported by Raja R. Harinath.
6426 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6427 * bin/autoupdate.in: Use error instead of die.
6429 2002-09-01 Paul Eggert <eggert@twinsun.com>
6431 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6432 ordinary shell concatenation rather than echo+tr+sed command that
6433 runs afoul of a long-line-related sed bug in Solaris 8.
6435 * bin/autoheader.in (parse_args): --warning -> --warnings.
6437 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6438 stdout, as traditional "ls" does.
6439 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6440 _AC_COMPILER_EXEEXT_O): Likewise.
6441 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6443 * bin/autoconf.as: Add --prepend-include option. This patch was
6444 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6445 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6447 * bin/autoconf.in, configure: Regenerate.
6449 * doc/autoconf.texi (Special Shell Variables): Mention
6450 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6452 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6453 MAILPATH and set PS1, PS2, PS4 to default values, to work
6454 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6455 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6456 the Autoconf documentation specifies; fall back to "unset" only if
6457 this fails. Use a shell for-loop for this rather than an m4 loop,
6458 to shorten the output script.
6460 2002-08-30 Paul Eggert <eggert@twinsun.com>
6462 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6463 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6464 for the CDPATH problem. Document PWD.
6465 (Limitations of Builtins): Document the problem that "cd $foo" and
6466 "ls $foo" may refer to different directories in shells conforming
6467 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6468 example, since the old example is now out of date.
6470 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6471 FOO" and "ls FOO" talk about different directories; this catches
6472 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6473 spaghetti.
6475 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6476 of rolling our own unset.
6477 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6478 in practice we needn't worry about CDPATH if unset doesn't work.
6480 * Makefile.in, aclocal.m4, bin/Makefile.in,
6481 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6482 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6483 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6484 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6485 tests/Makefile.in: Regenerate with Automake 1.6.3.
6487 * config/config.guess, config/config.sub, config/mkinstalldirs:
6488 Update.
6490 * configure: Regenerate with self.
6492 2002-08-30 Kevin Ryde <user42@zip.com.au>
6494 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6495 default output.
6497 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6499 * bin/autom4te.in (Request::load): Correctly test for "do" read
6500 failure.
6502 2002-08-29 Akim Demaille <akim@epita.fr>
6504 * lib/Autom4te/General.pm (&xqx): New.
6505 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6506 hand, which is not portable.
6507 (&error): New.
6508 * bin/autom4te.in: Use them.
6509 Use &error instead of die.
6510 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6511 Adjust.
6513 2002-08-17 Paul Eggert <eggert@twinsun.com>
6515 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6516 default list of compilers to try, since it was long ago superseded
6517 by the ksh fc builtin. Suggested by Steven G. Johnson.
6519 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6521 * doc/autoconf.texi (Invoking autom4te): End the option table,
6522 fixing a bug introduced by the previous patch.
6523 (Limitations of Make): Add a 'target lookup' subentry in the
6524 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6526 2002-07-29 Mark D. Roth <roth@feep.net>
6528 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6529 options and use $AUTOM4TE_PATH.
6530 * doc/autoconf.texi: Remove documentation of autom4te
6531 --include-envvar and --site-macro-subdir options and document
6532 use of $AUTOM4TE_PATH.
6533 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6534 arguments from each language section.
6536 2002-07-29 Paul Eggert <eggert@twinsun.com>
6538 * doc/install.texi: Include copyright symbol in copyright notice.
6540 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6541 Replace with:
6542 (AM_MAKEINFOFLAGS): New macro.
6543 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6544 * Makefile.am (INSTALL): Use the new macros.
6545 Use -o rather than --output, since "missing" does not grok --output.
6547 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6549 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

6551 `make -k'.
6553 2002-07-24 Kevin Ryde <user42@zip.com.au>
6555 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6556 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6558 2002-07-23 Paul Eggert <eggert@twinsun.com>
6560 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6561 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6562 apparently treats PATH="nonexistent" as if it contained ".".
6563 Bug reported by Stefan `Sec' Zehl.
6565 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

6685 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
6686 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
6687 so that Emacs setups GNU style for perl-mode and cperl-mode.
6689 2002-06-27 Paul Eggert <eggert@twinsun.com>
6691 * config/install-sh: Quote $src. Prefer || to test's -o option,
6692 as per "Limitations of Builtins".
6693 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
6694 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6696 * tests/mktests.sh: Use grep instead of fgrep, as per
6697 "Limitations of Builtins".
6699 2002-06-15 Paul Eggert <eggert@twinsun.com>
6701 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

6703 so that we consistently test the just-built programs.
6704 * tests/wrappl.as: Likewise.

6716 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
6717 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
6718 on Solaris 2.5.1.
6720 2002-06-11 Andreas Schwab <schwab@suse.de>
6722 * doc/autoconf.texi: Add more dir entries.
6724 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
6726 * bin/autom4te.in ($cache): Don't define using `$me', the name
6727 of the cache should not depend on the name under which autom4te
6728 was installed.
6730 2002-06-07 Akim Demaille <akim@epita.fr>
6732 * tests/tools.at (autoconf: forbidden tokens, basic)

6734 words in autom4te.in.
6736 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
6738 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
6739 _AC_LANG_PROGRAM_C_F77_HOOKS.
6741 2002-06-07 Akim Demaille <akim@epita.fr>
6743 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
6744 rename as...
6745 (AC_REPLACE_FNMATCH): this.

6747 AC_FUNC_FNMATCH_GNU.
6749 2002-06-07 Akim Demaille <akim@epita.fr>
6751 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
6752 Rosetta Stone for Unix.
6754 2002-06-07 Akim Demaille <akim@epita.fr>
6756 * bin/autom4te.in (warn_forbidden): When rejecting a token,
6757 suggest m4_pattern_allow.
6758 Suggested by Adam J. Richter.
6760 2002-06-07 Akim Demaille <akim@epita.fr>
6762 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
6763 ac_config_libobj_dir.
6764 (AC_CONFIG_LIBOBJ_DIR): New.
6765 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
6766 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
6767 Use ac_config_libobj_dir to find the replacement files.
6768 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
6769 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

6772 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
6773 * tests/mktests.sh (ac_exclude_list): Don't check

6776 2002-06-06 Paul Eggert <eggert@twinsun.com>
6778 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
6779 if ln doesn't work.
6780 * NEWS: Likewise.
6781 * doc/autoconf.texi (Configuration Links): Likewise.

6784 2002-06-05 Paul Eggert <eggert@twinsun.com>
6786 * config/config.guess, config/config.sub, config/texinfo.tex:
6787 Update from masters.
6789 2002-05-29 Paul Eggert <eggert@twinsun.com>
6791 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

6816 2002-05-23 Akim Demaille <akim@epita.fr>
6818 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
6819 version of Autoconf that is discussed.
6821 2002-05-22 Paul Eggert <eggert@twinsun.com>
6823 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
6824 from the default list of compilers to try. Suggested by
6825 Kate Hedstrom.
6826 * NEWS: Document the above.
6827 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
6829 2002-05-17 Paul Eggert <eggert@twinsun.com>
6831 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
6832 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6833 This improves on an earlier suggestion by H. Peter Anvin.
6835 2002-05-16 Paul Eggert <eggert@twinsun.com>
6837 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6838 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6839 Both macros now accept an optional source-dir arg.
6840 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6842 * NEWS: Document this.
6843 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6845 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6846 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6847 not for GNU extensions; this undoes part of the 2000-11-03 change,
6848 reverting to 2.13-compatible behavior.
6849 Add new optional argument DIR.
6850 (AC_FUNC_FNMATCH_GNU): New macro.
6852 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6854 2002-05-08 Paul Eggert <eggert@twinsun.com>
6856 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6857 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6858 and it causes a 'test' syntax error if it fails.
6859 Bug reported by Stephen Gildea.
6861 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6862 If prototypes are supported, use them to check this at compile-time,
6863 instead of trying to check it at run-time. If we must do a run-time
6864 check, assume that setvbuf is standard when cross-compiling, as
6865 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6866 Bug reported by Paul D. Smith.
6868 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6869 argument specifying location of getloadavg.c. This removes a
6870 FIXME. This idea was taken from Jim Meyering's implementation in
6871 textutils.
6872 * doc/autoconf.texi (Particular Functions): Document this.
6873 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6874 that's what the code does; this fixes a bug reported by
6875 Paul D. Smith.
6877 2002-05-03 Akim Demaille <akim@epita.fr>
6879 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6880 autopoint instead of gettextize.
6881 ($uses_alocal): Rename as...
6882 ($uses_aclocal): this.
6883 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6884 Suggested by Bruno Haible.
6886 2002-05-03 Akim Demaille <akim@epita.fr>
6888 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
6890 2002-04-29 Paul Eggert <eggert@twinsun.com>
6892 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
6893 files to be 1 second older; just set them to be the same time.
6894 Also, sleep 1 second after the first aclocal, to work around
6895 problems with sub-second time stamps on the input files.
6897 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6899 * doc/autoconf.texi: Mention "set -e -x" lossage
6900 under node "Limitations of Builtins".
6902 2002-04-29 Akim Demaille <akim@epita.fr>
6904 * doc/install.texi: Better wording for setting variables when
6905 running configure.
6906 From Christian Cornelssen.
6908 2002-04-29 Akim Demaille <akim@epita.fr>
6910 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
6911 of lack of $LINENO support, then the test will compare the $LINENO
6912 in testsuite vs. the lineno in the test file. This is wrong, of
6913 course.
6914 Be sure to protect it.
6915 Reported by Patrick Welche.
6917 2002-04-25 Akim Demaille <akim@epita.fr>
6919 * doc/autoconf.texi (Obsolete Macros): Typo.
6920 Reported by Vladimir Volovich.
6922 2002-04-25 Akim Demaille <akim@epita.fr>
6924 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
6925 than some of the input files, hence, on the second run of aclocal,
6926 if some of its input are younger, make them older.
6927 Suggested by Paul Eggert.
6929 2002-04-25 Akim Demaille <akim@epita.fr>
6931 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
6932 Thanks to Paul Eggert.
6934 2002-04-25 Akim Demaille <akim@epita.fr>
6936 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
6937 and ac_subst_vars be sh variables containing the list of
6938 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
6939 DEFAULT diversion.
6940 (_AC_INIT_PREPARE): Use them to log them.
6941 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
6942 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
6943 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
6944 _AC_SUBST_FILES and _AC_SUBST_VARS.
6945 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
6947 2002-04-24 Akim Demaille <akim@epita.fr>
6949 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
6950 autoheader, so that automake does not complain about a missing
6951 config.h.in that was to be created.
6953 2002-04-23 Akim Demaille <akim@epita.fr>
6955 * bin/autoheader.in (parse_args): --warning takes an argument.
6956 Fixes PR/220.
6958 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
6960 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

6975 Reported by Gregory Giannoni.
6977 2002-04-22 Akim Demaille <akim@epita.fr>
6979 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

7008 Sample Texts sections of the Texinfo 4.2 manual. Most
7009 importantly, this makes sure that the copyright notices appear in
7010 all output formats. You probably need Texinfo 4.2 to generate

7039 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7040 from aclocal.m4 too.
7042 2002-04-12 Akim Demaille <akim@epita.fr>
7044 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7046 2002-04-10 Akim Demaille <akim@epita.fr>
7048 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7049 workaround for ${1+"$@"}.
7050 * doc/autoconf.texi (Shell Substitutions): Explain it.
7051 From Oliver Kiddle and Peter Stephenson.
7053 Have M4sh perform minimal shell sanitizing.
7055 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7056 part into...
7057 (_AS_PREPARE): this new macro.

7060 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7062 Adjust Autoconf and Autotest.

7065 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7066 * lib/autotest/general.m4 (AT_INIT): Likewise.
7067 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7068 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7069 AS_SHELL_SANITIZE.
7071 Use this M4sh to generate Autoconf's shell scripts.
7073 * tests/wrapsh.as: New, precursor of wrapsh.in.
7074 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7075 on Autotest and M4sh.
7076 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7077 (wrapsh.in): New target.
7078 * bin/autoconf.as: New, precursor of autoconf.in.
7079 (autoconf.in): New target.
7081 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
7083 * doc/autoconf.texi (Limitations of Make): Mention the issue
7084 with indented comments in rules.

7094 (Portable Shell): Cross reference to Systemology.
7096 2002-04-05 Akim Demaille <akim@epita.fr>
7098 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7099 directories when descending in a SUBDIRS.
7100 Reported by Ezra Peisach.
7102 2002-04-04 Andreas Schwab <schwab@suse.de>
7104 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7105 contains no literal separators.
7107 2002-04-03 Akim Demaille <akim@epita.fr>
7109 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7110 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7111 Use dnl, not the KILL diversion.
7112 Extracted from...
7113 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7114 (AC_CONFIG_LINKS): here.
7115 Adjust.
7116 Don't use the KILL diversion, as it kills spurious output, which
7117 results in failures being hidden.
7118 Use m4_defn where appropriate.
7119 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7120 after the second argument.
7121 Use m4_defn.
7122 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7123 syntax, as it is provided by M4sugar.

7151 (AC_C_CONST): Same.

7165 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7166 to avoid versions of HP C which don't allow that.
7168 2002-03-27 Paul Eggert <eggert@twinsun.com>
7170 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7171 (AS_SHELL_SANITIZE): Invoke it.

7178 2002-03-26 Akim Demaille <akim@epita.fr>

7182 2002-03-25 Paul Eggert <eggert@twinsun.com>
7184 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7185 as POSIX requires, as it doesn't work with Zsh.
7186 * doc/autoconf.texi (Assignments): Document the problem.
7188 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7190 * doc/autoconf.texi (Limitations of Make): Mention more issue
7191 about VPATH, overriding of macros in sub-makes, and handling of
7192 SHELL.
7194 2002-03-21 Paul Eggert <eggert@twinsun.com>
7196 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7197 problem with here-document buffer boundaries.
7199 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7200 when reinvoking the shell, to work around problems with installers
7201 who put strange things like "cd" commands in their environments.
7203 2002-03-19 Akim Demaille <akim@epita.fr>
7205 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7206 From Aaron Ucko.
7208 2002-03-19 Akim Demaille <akim@epita.fr>
7210 * bin/autoscan.in (scan_file): Specify the location in `&used'
7211 invocations.
7212 From Nicolas Joly.
7214 2002-03-19 Akim Demaille <akim@epita.fr>
7216 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7217 From Nishio Futoshi.
7219 2002-03-19 Akim Demaille <akim@epita.fr>
7221 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

7225 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7226 (Limitations of Usual Tools): Add mkdir section.
7228 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7229 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7230 back on AS_DIRNAME to compute prefixes otherwise; this is
7231 roughly what mkinstalldirs does. That way, we need not have
7232 our own filename disassembler. The old disassembler did not
7233 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7235 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7236 Create at_test_all by a series of assignments,
7237 not by a single assignment of a long string. The latter causes ksh
7238 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7239 presumably because of a buffer overrun.
7241 2002-03-14 Paul Eggert <eggert@twinsun.com>
7243 * lib/autotest/general.m4 (at_times_skip):
7244 Renamed from at_times. Now a boolean.
7245 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7246 says 'times: not found'.
7248 2002-03-14 Akim Demaille <akim@epita.fr>
7250 * bin/autoreconf.in (&study_gettextize): New.
7251 (&autoreconf): Handle newest gettextize.
7252 Rerun aclocal if needed.
7253 Suggested by Andreas Schwab.
7255 2002-03-13 Akim Demaille <akim@epita.fr>

7262 Add information about stdint.h and inttypes.h from Paul Eggert.
7264 2002-03-13 Akim Demaille <akim@epita.fr>
7266 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7267 -p'.
7268 From Bob Proulx.
7270 2002-03-12 Akim Demaille <akim@epita.fr>
7272 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7273 m4_require.
7275 2002-03-11 Andreas Schwab <schwab@suse.de>
7277 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7278 does not do it if --with-lispdir is given.
7280 2002-03-08 Akim Demaille <akim@epita.fr>
7282 Version 2.53.
7284 2002-03-08 Akim Demaille <akim@epita.fr>
7286 * doc/autoconf.texi (Subdirectories): Clarify that the
7287 subdirectory should exist.
7289 2002-03-08 Akim Demaille <akim@epita.fr>
7291 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7293 2002-03-08 Akim Demaille <akim@epita.fr>
7295 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7296 aliases the actual variables, and modifications of the former
7297 affect the latter.
7299 2002-03-08 Akim Demaille <akim@epita.fr>
7301 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7302 because of C-c: have m4 output in tmp files, then mv them.
7304 2002-03-08 Akim Demaille <akim@epita.fr>
7306 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7307 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7308 * bin/ifnames.in: Copyright update.

7314 2002-03-05 Akim Demaille <akim@epita.fr>
7316 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7317 Kevin Ryde.
7319 2002-03-05 Akim Demaille <akim@epita.fr>

7325 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7326 * lib/autoconf/general.m4 (AC_INIT): More informative error
7327 message for LIBOBJ.
7329 2002-03-04 Akim Demaille <akim@epita.fr>
7331 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7332 parallel builds.
7334 2002-03-04 Akim Demaille <akim@epita.fr>
7336 * doc/autoconf.texi (Transforming Names): Equality between target
7337 and host is irrelevant.
7338 (Specifying Names, Canonicalizing): Remove all references to the
7339 backward compatibility hooks. Rather, collect them all into...
7340 (Hosts and Cross-Compilation): this new section.
7341 * doc/install.texi (System Type): Ditto.
7342 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7343 that `--host' implies cross-compilation.
7345 2002-03-04 Akim Demaille <akim@epita.fr>
7347 * doc/autoconf.texi (Evaluation Macros): New.
7348 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7349 useless.
7350 (_m4_foreach): Define the variant with immediate evaluation so
7351 that it contains exactly the items, not an expression which
7352 evaluation is the current item.
7353 (m4_re_string, m4_re_word): Don't over quote them.
7355 2002-03-04 Akim Demaille <akim@epita.fr>
7357 Instead of having stacking `shift's evaluated at the end, let
7358 `foreach' loops immediately evaluate them.
7360 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7361 $*. This is the n-th time I change my mind, but hopefully this is
7362 the last...
7363 (m4_lquote): New.
7364 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7365 efficient.
7366 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7367 it was only a hack for m4_text_wrap.
7368 (m4_car2): Remove, replaced by...
7369 (m4_cdr): New.
7370 (_m4_foreach): Adjust.
7371 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7372 m4_bpatsubst for clarification.

7424 AC_PREFIX_PROGRAM fails with dashed program names
7426 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7427 variable when looking for the prefix program.
7428 Now it also works for shell variables.

7433 case/esac.

7437 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7438 case/esac, some shells don't support it.
7439 Reported by Zack Weinberg.

7461 to this file.

7465 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

7487 * bin/autom4te.in (&parse_args): Implement `frozen files are
7488 optional are the sum of the previous files on the command line'.
7489 Also, pass `--reload-state=' on them, so...
7490 (handle_m4): don't.
7491 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7492 (M4sh): Rely on M4sugar.

7498 * doc/autoconf.texi (Initializing configure): Adjust.
7500 2002-01-30 Akim Demaille <akim@epita.fr>
7502 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7503 alphanumeric to `-' instead of `_'.
7505 2002-01-30 Akim Demaille <akim@epita.fr>
7507 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7508 for plain code, the other for cross-compilation code. The latter
7509 is now run with GCC only.
7510 * doc/autoconf.texi (Compilers and Preprocessors): New.
7512 2002-01-30 Akim Demaille <akim@epita.fr>
7514 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7515 values.
7516 * doc/autoconf.texi (Initializing configure): Explain how to
7517 change AC_INIT default values.
7519 2002-01-29 Akim Demaille <akim@epita.fr>
7521 * tests/torture.at (Configuring subdirectories): Use configure.in,
7522 so that aclocal 1.4 works.
7523 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7525 2002-01-28 Akim Demaille <akim@epita.fr>
7527 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7528 needs an argument.
7530 2002-01-28 Akim Demaille <akim@epita.fr>
7532 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7533 AUTOTEST_PATH *after* it was set.
7534 Don't put `.' in the PATH: the user should be precise and `./' if
7535 needed. In addition, given that the test suite does some `cd', if
7536 `.' is in the path, the `tested programs' sections will report
7537 programs found in the test suite's directory, while during the
7538 tests (performed in their own directory), these programs are no
7539 longer visible. In other words, the results is confusing and
7540 useless.
7541 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7543 2002-01-24 Akim Demaille <akim@epita.fr>
7545 Version 2.52g.

7571 Automake.
7573 2002-01-24 Akim Demaille <akim@epita.fr>
7575 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)

7606 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7607 package.m4, since is really depends upon configure.ac, not
7608 configure.
7609 * doc/autoconf.texi (testsuite Scripts): Adjust.
7610 * tests/Makefile.am (package.m4): New.
7611 EXTRA_DIST it since its a source.
7613 2002-01-06 Akim Demaille <akim@epita.fr>
7615 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7616 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7617 and PACKAGE_BUGREPORT from here...
7618 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7619 arguments.
7620 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7621 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7622 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7623 * tests/tools.at (autoheader): Adjust.
7624 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

7630 2002-01-03 Akim Demaille <akim@epita.fr>
7632 * doc/autoconf.texi (Output): Improved wording regarding use of

7639 sometimes needing writable input.
7641 2001-12-17 Jim Meyering <meyering@lucent.com>
7643 * doc/autoconf.texi (New Macros): Tweak wording.
7645 2001-12-14 Akim Demaille <akim@epita.fr>
7647 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7648 trailing files, don't apply `-rf' to files which might not be
7649 created by configure (core, core.*, and *.core), but just `rm -f'.
7650 Suggested by Jonathan Kamens.
7652 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7654 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7656 2001-12-14 Akim Demaille <akim@epita.fr>
7658 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7660 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

7663 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7664 abs_srcdir, top_srcpath to abs_top_srcdir.
7665 (_AC_OUTPUT_FILES): Adjust.
7666 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7667 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7668 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7670 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
7672 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
7673 C/Fortran linking on HP/UX, by extracting the Fortran library
7674 search path from the LPATH line in the $F77 -v output.
7676 2001-12-12 Kevin Ryde <user42@zip.com.au>
7678 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7679 forbidden file descriptors table.
7681 2001-11-26 Akim Demaille <akim@epita.fr>
7683 * bin/autoscan.in (%c_keywords): Build it at top level.
7684 Map to 1 in order to simplify its uses.
7686 2001-11-26 Akim Demaille <akim@epita.fr>
7688 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7689 Remove $filepath, useless.
7690 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7691 variables, they are really part of the tokens.
7692 Split the input line on spaces and then look for tokens.
7693 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7694 because of `lex$U.$(OBJEXT)'.
7695 (&scan_files): Use "@list" instead of join.
7696 * doc/Makefile.am (CLEANFILES): Add *.fns.
7698 2001-11-26 Akim Demaille <akim@epita.fr>

7705 * lib/autoscan/headers: errno.h is portable.
7707 2001-11-26 Akim Demaille <akim@epita.fr>
7709 * bin/autoscan.in (used): New.
7710 Use it.
7712 2001-11-26 Akim Demaille <akim@epita.fr>
7714 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7715 directives.
7716 (&scan_sh_file): Remove a duplicate pattern.
7717 (&check_configure_ac): Use long options.
7718 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
7720 2001-11-26 Akim Demaille <akim@epita.fr>
7722 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
7723 Before, having a line containing the opening of a multi line
7724 comment made the whole line be ignored.
7726 2001-11-26 Akim Demaille <akim@epita.fr>
7728 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7729 (testsuite Scripts): Be one of its subsection.
7730 (Autotest Logs): New.
7732 2001-11-26 Akim Demaille <akim@epita.fr>
7734 Test groups are now run two directories deeper.
7736 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7737 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7738 at_top_builddir.
7739 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7740 top_srcdir, builddir and top_builddir.
7741 Use `at_*dir' relatively to the directory containing the
7742 suite, use `*dir' when relatively to the current group dir.
7744 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7746 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7747 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7748 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7749 spelling errors.
7751 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7753 * doc/autoconf.texi (Using System Type): Add an example of `case
7754 $host' usage so people quit using `case $target' everywhere.
7756 2001-11-22 Akim Demaille <akim@epita.fr>
7758 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7759 spotted by Jim Meyering.
7761 2001-11-16 Paul Eggert <eggert@twinsun.com>
7763 This patch implements a `long double' suggestion by Oliver Kiddle.
7765 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7766 static, to catch errors if the value isn't known at compile-time
7767 and the compiler supports dynamic arrays. Change its name from
7768 `_array_' to `test_array' to avoid potential name clashes.
7769 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7770 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7771 better than double. Catch a bug in GCC 2.95.2 x86.
7772 * doc/autoconf.texi (C Compiler): Document the above.
7773 * NEWS: Likewise.
7775 2001-11-13 Akim Demaille <akim@epita.fr>
7777 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7778 hand.
7779 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7781 2001-11-13 Akim Demaille <akim@epita.fr>
7783 * lib/autotest/general.m4 (AT_INIT): After having run the test
7784 group, go back to the initial directory, not to at_suite_dir.
7786 2001-11-13 Akim Demaille <akim@epita.fr>
7788 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7789 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7790 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7791 option.
7792 (AT_CHECK_CONFIGURE): Use absolute paths.
7793 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7794 The problem is still the old one: there is no means in M4 (that I
7795 know about) to create a defining macro, because there is no means
7796 to create `$1' etc., therefore, the defining macro ``swallows''
7797 all the arguments meant to the defined macro.
7799 2001-11-13 Akim Demaille <akim@epita.fr>
7801 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7802 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7803 configure.ac.
7804 * tests/aclocal.m4: Remove, as it is no longer used.
7806 2001-11-13 Akim Demaille <akim@epita.fr>
7808 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7809 variable names when referring to a single test group, or to
7810 `suite' when referring to the whole test suite.
7811 `at_last_test' is removed: m4 compute at_format itself.
7812 (at_stdout, at_stder1, at_stderr): New variables.
7813 (AT_CHECK): Use them.
7815 2001-11-13 Akim Demaille <akim@epita.fr>
7817 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7818 in PATH.
7819 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7820 Do it as soon as a test fails, don't wait till the end of the test
7821 suite.
7822 Don't remove $as_me.[0-9]*, since these files no longer exist.
7824 2001-11-13 Akim Demaille <akim@epita.fr>
7826 * tests/tools.at: Use absolute paths, since we are no longer run
7827 in place.
7829 2001-11-13 Akim Demaille <akim@epita.fr>
7831 Now that tests are running in their own private dir, there is no
7832 need to list the files to remove at the end of tests groups.
7834 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7835 (AT_data_files, at_data_files): Remove.
7836 (AT_CLEANUP, AT_DATA): Simplify.
7837 (AT_INIT): Adjust.
7838 Remove the group dir if !debug && !failed.
7839 * tests/atspecific.m4: Adjust.
7841 2001-11-13 Akim Demaille <akim@epita.fr>
7843 Start a new layout for Autotest: `testsuite' creates
7844 `testsuite.dir' in which the at-check-line etc. files are to be
7845 found, and `testsuite.dir/003' where the test group 3 is run.
7847 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7848 at_check_line_file, at_format, at_test_normalized, at_group_dir
7849 are new variables.
7850 Create the directories.
7851 Use absolute paths for at- files.
7852 (AT_CHECK): Adjust.
7854 2001-11-11 Michael Matz <matz@kde.org>
7856 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7857 (m4_car2): New.
7858 (m4_car): Properly quote arguments.
7860 2001-11-13 Akim Demaille <akim@epita.fr>
7862 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7863 with stricter rules on LIBOBJS.
7865 2001-11-12 Paul Eggert <eggert@twinsun.com>
7867 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7868 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7869 __PROTOTYPES too.
7871 2001-11-12 Akim Demaille <akim@epita.fr>
7873 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7875 2001-11-12 Akim Demaille <akim@epita.fr>
7877 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7878 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7879 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7880 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7881 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7882 specify to what the macro should be defined (typically to 1).
7884 2001-11-12 Akim Demaille <akim@epita.fr>
7886 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7887 From Jim Meyering.
7889 2001-11-12 Akim Demaille <akim@epita.fr>
7891 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
7892 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
7893 definition used by Automake where LEX is +/- "${missing} lex" and
7894 `missing' itself contains variables.
7896 2001-11-12 Akim Demaille <akim@epita.fr>
7898 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7899 Now that M4sh pushes BODY, the comments were output at the end of
7900 the test suites.
7902 2001-11-08 Akim Demaille <akim@epita.fr>
7904 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7905 that we can trace macros from aclocal.m4.
7906 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7907 obsoleted, and redirect to the former anyway.
7908 Reported by Ralf Corsepius.
7910 2001-11-08 Akim Demaille <akim@epita.fr>
7912 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
7913 processed only if present.
7914 * tests/torture.at (Configuring subdirectories): Use autoreconf
7915 instead of successive calls to autoconf.
7916 Add a nonexistent subdirectory to exercise the patch above.
7917 Reported by Ralf Corsepius.
7919 2001-11-08 Kevin Ryde <user42@zip.com.au>
7921 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
7922 doesn't accept .S files.
7924 2001-11-07 Akim Demaille <akim@epita.fr>
7926 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
7927 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
7928 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
7929 * bin/autom4te.in (warn_forbidden): New.
7930 (handle_output): Use it.
7931 Read m4_pattern_forbid with messages.
7933 2001-11-05 Akim Demaille <akim@epita.fr>
7935 * bin/autom4te.in (--normalize): Remove.
7936 * lib/autom4te.in: Adjust.
7938 2001-11-05 Akim Demaille <akim@epita.fr>
7940 * tests/Makefile.am (testsuite): Rename this target as...
7941 ($(TESTSUITE)): this.
7942 From Nicolas Joly.
7944 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
7946 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
7947 the --prefix option, also remove it's argument.
7949 2001-11-05 Akim Demaille <akim@epita.fr>
7951 * doc/autoconf.texi (testsuite Invocation): Update.
7952 (Writing testsuite.at): Update.
7954 2001-11-03 Akim Demaille <akim@epita.fr>
7956 * doc/autoconf.texi: s/@code/@command/ where appropriate.
7958 2001-11-03 Akim Demaille <akim@epita.fr>
7960 * lib/Autom4te/General.pm: (&catfile, &canonfile)
7961 (&file_name_is_absolute): New, wrappers around routines from
7962 File::Spec.
7963 Use and export them.
7964 (&find_configure_ac): Optionally take a directory where to look at.
7965 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
7966 the arguments.
7967 Default @ARGV to `.', not find_configure_ac.
7968 (&autoreconf): Argument is a directory.
7969 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
7970 * doc/autoconf.texi (autoreconf Invocation): Update.
7972 2001-11-03 Akim Demaille <akim@epita.fr>
7974 * lib/Autom4te/General.pm (@export_vars, @export_subs)
7975 (@export_forward_subs): New.
7976 Add basename, dirname, and fileparse.
7977 (@EXPORT): Adjust.
7978 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
7979 Don't look for aclocal flags if we already know aclocal is not
7980 used.
7981 Move aclocal.m4t only if it exists.
7982 Reported by Ezra Peisach.
7984 2001-11-03 Akim Demaille <akim@epita.fr>
7986 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
7987 passed on command line, defaulting to ./configure.ac if present.
7988 (&maybe_autoreconf, File::Find): Remove, unused.
7989 (&autoreconf): If autoconf is not used, don't try to trace.
7991 2001-11-02 Akim Demaille <akim@epita.fr>
7993 * configure.ac: Bump to 2.52g.
7995 2001-11-02 Akim Demaille <akim@epita.fr>
7997 Version 2.52f.
7999 2001-11-02 Akim Demaille <akim@epita.fr>
8001 * config/config.guess, config/config.sub, doc/standards.texi:
8002 * config/lispdir.m4: Update from masters.
8003 * configure.ac: Bump to 2.52f.
8005 2001-11-02 Akim Demaille <akim@epita.fr>
8007 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8008 Don't run aclocal when aclocal.m4 is not from aclocal.
8009 From Ezra Peisach.
8010 Don't run libtoolize and gettextize if --install is not given.
8012 2001-11-01 Paul Eggert <eggert@twinsun.com>
8014 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8015 be invoked before _AS_LINENO_PREPARE.
8016 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8017 than character ranges.
8019 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8020 invoking AS_BASENAME. Set the locale variables to 'C' if
8021 possible, as POSIX requires this to get the traditional
8022 behavior.
8023 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8025 2001-10-31 Paul Eggert <eggert@twinsun.com>
8027 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8028 with {}, as that triggers a bug in Bash 2.05.
8030 (_AS_LINENO_PREPARE): Use Sed rather than
8031 Awk. Fix the sed prepass to work even if there are multiple
8032 instances of $LINENO on the same line. Do not substitute for
8033 other variables like $LINENOT. Do not check file dates; such a
8034 check is unreliable on sufficiently fast machines, and removing
8035 the check makes the code simpler and more reliable. Check for
8036 output and chmod failures.
8038 * doc/autoconf.texi (Special Shell Variables): Document
8039 the above.
8041 2001-10-31 Akim Demaille <akim@epita.fr>
8043 * tests/Makefile.am (atconfig): Remove this target, Automake
8044 handles it now.
8046 2001-10-31 Akim Demaille <akim@epita.fr>
8048 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8049 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8050 provided, while it is optional.
8051 * configure.ac: Adjust.
8053 2001-10-26 Paul Eggert <eggert@twinsun.com>
8055 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8056 lib/Autom4te/Struct.pm:
8057 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8058 with 5.005_02.
8060 * doc/autoconf.texi (Special Shell Variables): Document some
8061 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8063 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8064 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8065 eval $LINENO is not portable in practice.
8067 2001-10-24 Akim Demaille <akim@epita.fr>
8069 * lib/Autom4te/General.pm (backname): New.
8071 2001-10-24 Akim Demaille <akim@epita.fr>

8081 2001-10-22 Paul Eggert <eggert@twinsun.com>
8083 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8084 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8085 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8086 POSIX decided to standardize on the int flavor of strerror_r.
8087 Always do char* test, as there's no reason not to.
8088 Assign to a char* var, to catch strerror_r that returns int*.
8090 * doc/autoconf.texi (Particular Functions):
8091 Document the above changes. Also, document the fact that
8092 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8094 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8096 2001-10-20 Akim Demaille <akim@epita.fr>

8103 * lib/Autom4te/General.pm (&update_file): If destination is
8104 unchanged, remove the source.

8107 (&autoreconf): Display the full path of the configure.ac we are
8108 studying.
8109 Trace it only once.
8110 Be sure to honor --force with gettextize.
8111 Always run aclocal.
8112 * doc/autoconf.texi: Adjust.
8114 2001-10-20 Akim Demaille <akim@epita.fr>
8116 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8117 Remove, dead.
8118 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8119 `intl' is already present, as it refuses unless --force.
8120 (&parse_args): Use -I, --include instead of the old Autoconf
8121 options.
8122 ($localdir, $autoconf_dir): Remove.
8123 (@include): New.
8124 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8126 2001-10-19 Jens Petersen <petersen@redhat.com>
8128 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

8140 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
8141 comment, explain how to install automatic mode selection.
8142 From Russ Allbery.
8144 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8146 * bin/autoreconf.in (autoreconf): Display the path to the
8147 configure.ac being studied.
8149 2001-10-18 Paul Eggert <eggert@twinsun.com>
8151 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8152 long, to work around a bug in the HP C compiler version HP92453-01
8153 B.11.11.23709.GP.
8155 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8156 (AS_BASENAME_EXPR): New macro.
8157 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8158 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8159 and fall back on 'sed' only if the other two fail. This makes
8160 AS_BASENAME act more like AS_DIRNAME.
8161 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8162 contains white space.
8163 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8164 Use AS_DIRNAME, since I think it's now DOS-friendly.
8165 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8166 Allow "dirname //FOO" to return either / or //, as POSIX allows
8167 either behavior.
8169 2001-10-10 Akim Demaille <akim@epita.fr>
8171 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

8177 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

8215 (Syntax of the shell scripts): Don't.
8216 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
8217 bother with $force since...
8218 * lib/Autom4te/General.pm: does.
8220 2001-10-08 Akim Demaille <akim@epita.fr>
8222 * bin/autoreconf.in: Rewrite in Perl.
8223 * configure.ac: Adjust.

8305 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
8306 shell does not support LINENO, and if CONFIG_SHELL is unset or
8307 empty, and if we can find a shell that does support LINENO,
8308 then set CONFIG_SHELL to that shell and then re-execute
8309 ourselves with CONFIG_SHELL.
8311 2001-10-05 Paul Eggert <eggert@twinsun.com>
8313 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8314 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8315 build of $(TESTSUITE).
8317 2001-10-05 Akim Demaille <akim@epita.fr>
8319 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8356 compatibility with POSIX shells.

8385 Don't use nested parenthesization. This patch was originally

8394 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8395 Check for `expr' arithmetic overflow, and for compilation failure,
8396 and invoke a new argument $4 if either is discovered.
8397 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
8398 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
8400 2001-09-28 Akim Demaille <akim@epita.fr>

8426 (Broken/missing compilers, AC_PROG_CPP with warnings)
8427 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
8428 * tests/c.at (Extensions, C keywords)
8429 (Broken/missing compilers, AC_PROG_CPP with warnings)
8430 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
8431 (AC_PROG_CPP requires AC_PROG_CC): here and...
8432 * tests/fortran.at (GNU Fortran 77): there.
8433 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8434 AC_TRY_RUN is about compilation, not shell commands.
8435 (Test Programs): AC_TRY_RUN works as used to be advertised.
8437 2001-09-27 Akim Demaille <akim@epita.fr>
8439 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8440 Raja R Harinath:
8441 Be sure to detect when $LINENO always returns the same value.
8442 Look for the original script, basename($0) is certainly not
8443 enough.
8444 Pass the CLI arguments to `$as_me.lineno'.
8446 2001-09-25 Akim Demaille <akim@epita.fr>
8448 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
8449 Be sure the close and reopen the LOG fd before and after using tee

8536 2001-09-22 Akim Demaille <akim@epita.fr>
8538 * lib/autoconf/autotest.m4: Create `package.m4'.
8539 * tests/Makefile.am (package.m4): Remove.
8541 2001-09-22 Akim Demaille <akim@epita.fr>
8543 Rely on `$LINENO' when possible instead of `__oline__'.
8545 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
8546 `$LINENO' support replacement when not supported.
8547 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
8548 them explicitly to be sure they are not output before this section
8549 (via m4_require). Cosmetic only.
8550 * lib/autoconf/c.m4, lib/autoconf/general.m4,
8551 * lib/autoconf/programs.m4: Replace all the occurrences of
8552 `__oline__' with `$LINENO'.

8558 character (u: -> ue) in a code comment.
8559 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
8560 it works.
8562 2001-09-21 Akim Demaille <akim@epita.fr>
8564 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
8565 Suggested by Jim Meyering.
8567 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

8582 PATH_SEPARATOR.
8583 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
8584 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8585 be used instead of ':'.
8586 * lib/autotest/general.m4: Replace occurrences of ':' in
8587 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
8589 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

8592 arguments. Fixed a typo.
8594 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8596 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8597 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8599 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8601 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

8608 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8610 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8611 already have $file). Set output files to binary mode (helps avoid
8612 CR issues on DOSish systems).
8614 2001-09-19 Akim Demaille <akim@epita.fr>
8616 * lib/autotest/general.m4: Englishoes.
8617 From Tim Van Holder and Alexey Mahotkin.
8619 2001-09-18 Paul Eggert <eggert@twinsun.com>
8621 * doc/autoconf.texi (Common Shell Constructs): New node,
8622 documenting AS_DIRNAME.
8623 (Limitations of Usual Tools): Refer to it when discussing dirname.
8624 Also, update discussion of POSIX standard to reflect latest draft.
8626 * lib/autoconf/c.m4:
8627 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8629 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8630 Do not pass a first argument with leading '-'
8631 to expr, by parenthesizing initial integers that might be negative.
8633 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8634 now merely checks whether it is an error to pass an argument
8635 to getpgrp.
8637 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8638 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8639 whether it is a (compile-time) error to pass an argument to
8640 getpgrp. This simpler test supports the revised documentation,
8641 and is all that AC_FUNC_GETPGRP's users really need.
8643 2001-09-18 Akim Demaille <akim@epita.fr>
8645 * doc/autoconf.texi (Limitations of Make) <$<>: New.

8655 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8656 correctly.
8657 Add test for AS_BASENAME.
8658 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8659 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8660 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8661 * tests/base.at: Fixed the expected responses. The old ones were
8662 one line out...
8663 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8664 the documentation claims it should (and how it behaved in 2.13).
8666 2001-09-18 Akim Demaille <akim@epita.fr>
8668 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8669 the AC_CONFIG_COMMANDS invocation.
8670 This also solves the name clash problems.
8671 Don't set the package's ID.
8672 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8673 No longer to be shipped.
8674 (version.in): Remove.
8675 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8676 * lib/autoconf/status.m4: Adjust.
8677 Use `m4_PACKAGE_STRING'.
8678 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8679 the only optional argument is the name of the test suite.
8680 Expect `package.m4' to define the package signature.
8681 * lib/autom4te.in (Autotest): Add `package.m4?'.
8682 * tests/Makefile.am (package.m4): New.
8683 * tests/suite.at: ifnames is a victim.
8685 2001-09-18 Akim Demaille <akim@epita.fr>
8687 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8688 AC_LIBSOURCE, AC_CONFIG_FILES.
8689 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8690 program version string doesn't match the package's.
8691 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8692 after `(cached)'.
8694 2001-09-17 Paul Eggert <eggert@twinsun.com>
8696 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8697 Allow expression to return any value that can fit into unsigned long
8698 (not int, as before). Check for output errors.
8700 2001-09-17 Bruno Haible <haible@ilog.fr>
8702 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8703 Always include <stdio.h> and <stdlib.h>. Evaluate
8704 the expression in an extra function before these includes. Call
8705 fprintf "%d" only after ensuring the argument is of type 'int'.
8706 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8708 2001-09-17 Paul Eggert <eggert@twinsun.com>
8710 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8711 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8712 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8713 when they don't exist.
8715 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8716 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8717 need it.
8719 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8720 version with the version used by fileutils 4.1, except use
8721 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8722 we don't need it.
8724 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8726 2001-09-13 Akim Demaille <akim@epita.fr>
8728 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8729 _first_.
8730 Reported by Gerrit P. Haase.
8732 2001-09-13 Akim Demaille <akim@epita.fr>
8734 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8760 2001-09-13 Akim Demaille <akim@epita.fr>
8762 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8764 2001-09-13 Akim Demaille <akim@epita.fr>
8766 * lib/autotest/general.m4 (AT_INIT): Create and remove
8767 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8768 test suites can cohabit.
8770 2001-09-13 Akim Demaille <akim@epita.fr>
8772 * tests/mktests.sh: Don't output banners for empty test files.
8774 2001-09-13 Akim Demaille <akim@epita.fr>
8776 Test suites can be run independently of configure.

8794 * tests/ifnames: New.
8796 2001-09-13 Akim Demaille <akim@epita.fr>
8798 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
8799 test group titles.

8822 2001-09-10 Akim Demaille <akim@epita.fr>
8824 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
8825 PATH_SEPARATOR, let M4sh compute it.

8827 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

8840 2001-09-07 Akim Demaille <akim@epita.fr>

8845 related variables into `at_package_*'.

8871 to avoid GCC warnings.
8872 From Uwe Seimet.
8874 2001-09-05 Akim Demaille <akim@epita.fr>

8878 2001-09-05 Akim Demaille <akim@epita.fr>
8880 Be ready to handle filenames as stupid as `dnl.at', for if even
8881 the maintainer is dumb enough to do that...
8883 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8884 excellence in M4 quotation: consider `__file__' is active.
8886 And BTW, when invoking m4, pass the --include in the right order:
8887 the wrong one.
8889 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

8912 2001-09-05 Akim Demaille <akim@epita.fr>

8917 New, extracted from main.
8918 Use IO::File wherever possible.
8919 (input.m4): Be constant, use -I instead of hard coding $tmp.
8920 Therefore be a quoted heredoc.
8921 Don't invoke `_au_disable', since ac was not loaded, but just

8924 2001-08-31 Akim Demaille <akim@epita.fr>

8951 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
8952 (testsuite Scripts): There is no such thing as `atconfig.in'.
8953 And actually one diagram is missing: test suite runtime.
8955 2001-08-31 Akim Demaille <akim@epita.fr>
8957 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
8958 inverse order.
8960 2001-08-31 Akim Demaille <akim@epita.fr>
8962 * bin/autoupdate.in (@include): `installcheck' revealed the path
8963 to m4sugar was lacking!
8965 2001-08-31 Akim Demaille <akim@epita.fr>
8967 * man/Makefile.am (.x.1): We really have to pass
8968 autom4te_perllibdir.
8970 2001-08-31 Akim Demaille <akim@epita.fr>
8972 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
8973 debug scripts, in particular passing explicitly listed tests to
8974 run is stupid.
8976 2001-08-31 Akim Demaille <akim@epita.fr>
8978 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
8979 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
8980 Use directly autom4te, not autoconf.
8981 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
8983 2001-08-31 Akim Demaille <akim@epita.fr>
8985 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
8986 * bin/autoheader.in (%symbol): Strip arguments of macros.
8988 2001-08-31 Akim Demaille <akim@epita.fr>
8990 * doc/autoconf.texi: Catch up -I, --include changes.
8992 2001-08-31 Akim Demaille <akim@epita.fr>
8994 * bin/autom4te.in (&parse_args): Die on unknown languages.
8995 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
8996 need for autoconf.
8997 Promote --include over --macrodir and other obsolete options.
8999 2001-08-31 Akim Demaille <akim@epita.fr>
9001 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9002 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9003 * bin/autom4te.in ($autoconf): Pass --force.
9004 `print $out' doesn't print `$_' but `$out'.
9005 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9006 (autoheader): Pass --force since the test suite goes too fast for
9007 the time stamps.
9008 Adjust to the new autoheader messages.
9010 2001-08-31 Akim Demaille <akim@epita.fr>
9012 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9013 Check the completeness of the #template.
9014 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9015 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9016 invocation.
9018 2001-08-31 Akim Demaille <akim@epita.fr>
9020 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9021 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9022 Drop AC_MACRODIR dead for real.
9023 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9024 `autoheader: `config.hin' is created'.
9025 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9027 2001-08-31 Akim Demaille <akim@epita.fr>
9029 * bin/autoheader.in: Rewrite in Perl.
9030 * tests/autoheader: Adjust.
9032 2001-08-31 Akim Demaille <akim@epita.fr>
9034 * bin/autoconf.in (--include, -I): New option.
9035 Map --localdir, --autoconf-dir onto it.
9036 Forward autom4te's options instead of interpreting them.
9037 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9038 There is no such envvar since the inception of autom4te.cfg.
9039 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9040 * bin/autoupdate.in: Adjust, and perform more control.
9041 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9042 * tests/autoconf: Dittowise.
9044 2001-08-31 Akim Demaille <akim@epita.fr>
9046 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9047 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9048 optionally `FILE'.
9049 Use -e, not -f, since /dev/null for instance is OK.
9050 (&parse_args): Adjust.
9051 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9053 2001-08-31 Akim Demaille <akim@epita.fr>
9055 * configure.ac: Also find tested executables in bin.
9056 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9057 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9058 installed peer executables, only PATH is allowed to resolve it.
9059 Pass `autoconf_dir' via options, not via invisible envvars.
9060 * lib/Autom4te/General.pm (&find_peer): Remove.
9061 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9062 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9063 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9064 find the executables for it.
9065 * tests/Makefile.am: Major cleanup. Too lazy to document...
9066 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9067 We only need PERL.
9068 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9069 indeed related to running the test suite, while passing
9070 --autoconf-dir and others is related to running non installed
9071 Autoconf executables. So don't do that, leave it to...
9072 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9073 * tests/autoscan: New.
9074 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9075 refer to library files: rely on --language.
9077 2001-08-29 Akim Demaille <akim@epita.fr>
9079 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9080 s/--set/--language/.
9082 2001-08-29 Akim Demaille <akim@epita.fr>
9084 * doc/autoconf.texi: Strip the @nodes.
9085 Suggested by Paul Eggert.
9086 (Initializing configure): Typo.
9088 2001-08-29 Akim Demaille <akim@epita.fr>
9090 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9091 Suggested by Paul Eggert.
9093 2001-08-29 Akim Demaille <akim@epita.fr>
9095 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9096 download in a tmp dir.
9098 2001-08-29 Akim Demaille <akim@epita.fr>
9100 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9101 case insensitive OSes out there :(
9102 From Tim Van Holder.
9104 2001-08-29 Akim Demaille <akim@epita.fr>
9106 * lib/autom4te.in: New.
9107 * lib/Makefile.am (edit, autom4te.cfg): New.
9108 * bin/autom4te.in (BEGIN): Simplify.
9109 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

9111 (&parse_args): Support --mode, --set, and --melt.
9112 * bin/autoconf.in: Simplify and adjust.
9113 * tests/Makefile.am (AUTOMAKE): Use --set.
9114 * tests/atlocal.in: Adjust.
9115 * BUGS: distcheck and check are weak.
9117 2001-08-29 Akim Demaille <akim@epita.fr>
9119 * lib/autotest/general.m4: Use
9120 foo=`(command) 2>/dev/null`
9121 not
9122 foo=`command` 2>/dev/null
9123 (at-devnull): Rename as...
9124 (AT-devnull): this.
9125 (--clean): Remove AT-* files too.
9126 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
9127 Reported by Nicolas Joly.
9129 2001-08-28 Akim Demaille <akim@epita.fr>
9131 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
9132 quotes inside single quotes.

9139 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
9141 * lib/autotest/general.m4: Reword some messages.
9142 (AT_INIT): Check for the `times' builtin before using it.
9143 Support test ranges as arguments to the testsuite.
9144 Have -e imply -d as the help text suggested.
9146 2001-08-27 Akim Demaille <akim@epita.fr>
9148 * Makefile.maint: Formatting changes.
9149 (do-po-update, po-update, cvs-update, update): New targets.

9159 2001-08-27 Akim Demaille <akim@epita.fr>
9161 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9162 Support `VAR=VAL' as arguments.
9163 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
9164 may be set via the command line.
9166 2001-08-27 Akim Demaille <akim@epita.fr>
9168 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

9170 first the build dirs, then the src dirs.

9180 2001-08-27 Akim Demaille <akim@epita.fr>
9182 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
9183 `ac_top_builddir' to mimic Automake's vocabulary, which much more
9184 readable.
9185 Adjust callers.
9186 * doc/autoconf.texi (Configuration Actions): Document the vars
9187 available in commands.
9188 Emphasize the risks of collisions in init-cmds.

9192 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
9193 (Initializing configure): this new node.
9195 2001-08-27 Akim Demaille <akim@epita.fr>

9202 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): this.

9218 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
9219 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
9220 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
9221 -> ac_dir).
9222 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
9223 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
9225 2001-08-27 Akim Demaille <akim@epita.fr>

9250 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
9251 (AMTAR): Help automake define it.
9252 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
9253 needed, 1.5 can have a macro and a target with the same name.
9254 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
9255 * m4/strip.m4: New.

9268 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
9269 Adjust callers.
9270 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9271 the name of the directory they're in, instead of the filename,
9272 since version.m4 is now in m4sugar, but m4_acversion must not be
9273 classified as an Autoconf macro.
9274 ($input_m4): Don't qualify the path to m4sugar.
9275 Rather, pass autoconf_dir to m4.
9276 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
9277 * tests/suite.at: Require 2.52c.

9291 of config.log on traps.
9292 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
9293 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
9294 for config.status'.
9295 Open the log as soon as possible.
9296 Use the same log introduction as configure's.
9298 2001-08-22 Paul Eggert <eggert@twinsun.com>
9300 * doc/autoconf.texi (Indices): New node.
9301 Move indices out of the top level menu and into this submenu.
9303 2001-08-22 Akim Demaille <akim@epita.fr>
9305 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9306 AC_TRY_COMMAND.
9307 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
9309 2001-08-22 Akim Demaille <akim@epita.fr>
9311 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

9317 (AC_PROG_INSTALL, AC_PROG_LN_S, AC_RSH): Move to...
9318 * lib/autoconf/programs.m4: here.
9319 (_AC_DECL_YYTEXT): Rename as...
9320 (_AC_PROG_LEX_YYTEXT_DECL): this.
9321 * lib/autoconf/autoconf.m4, lib/autoconf/Makefile.am

9348 * configure.ac (AT_CONFIG): Fix the path.
9349 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
9350 can be used.
9352 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
9354 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
9355 program with AC_LANG_PROGRAM before feeding it to
9356 AC_COMPILE_IFELSE. Cleanup grep usage.
9358 2001-08-20 Akim Demaille <akim@epita.fr>
9360 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9361 * NEWS, README, README-alpha, TODO, tests/README: This package is
9362 `Autoconf', not `autoconf' (the executable).
9364 2001-08-20 Akim Demaille <akim@epita.fr>
9366 Info readers seem to need `Index' in the index node title :(
9368 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9369 simplified index node names.
9371 2001-08-20 Akim Demaille <akim@epita.fr>
9373 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
9374 arguments are not literals.
9375 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
9376 Specify the output variables, and macros defined.
9378 2001-08-20 Akim Demaille <akim@epita.fr>
9380 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
9381 (Examining Syntax) <AC_TRY_COMPILE>
9382 (Examining Libraries) <AC_TRY_LINK>
9383 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
9384 their arguments.
9385 Reported by Werner Lemberg.
9387 2001-08-20 Akim Demaille <akim@epita.fr>
9389 * lib/autotest/general.m4 (AT_INIT): Compute top_builddir,
9390 top_srcdir and srcdir from at_topbuild_2_topsrc and at_testdir.
9391 Load atlocal late enough to dump it in the log.

9404 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
9405 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
9406 test suite lives.
9407 Create `atconfig' automagically.
9408 Configure atlocal.in if present.
9409 * tests/atconfig.in: Remove.
9410 * tests/atlocal.in: New.
9411 * tests/Makefile.am: Adjust.
9413 2001-08-20 Akim Demaille <akim@epita.fr>
9415 Huh!?!?! There are still some user EOF tags used, which prevents

9482 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9483 `$0.log' as for projects where testsuite is in src, we'd have
9484 testsuite.log created in src.

9500 * doc/autoconf.texi: Work around Texinfo buglets.
9501 (Transformation Rules): One example is enough, users are expected
9502 to have their brains on. And BTW, use DESTDIR.
9503 (dvar): New macro. Use it.

9555 (cvs-dist): depends upon it.
9557 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9559 * tests/Makefile.am: Use a clean-local rule to remove
9560 autom4te.cache (it's a directory, not a file.
9561 * Makefile.am: Ditto (but maintainer-clean-local).
9563 2001-08-15 Akim Demaille <akim@epita.fr>
9565 * bin/autom4te.in (@m4_warning): New.
9566 (&handle_m4): Use it.
9567 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9568 warnings are issued at each run.
9569 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9570 is in the src tree.
9572 2001-08-15 Akim Demaille <akim@epita.fr>
9574 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9575 don't waste time running `autoupdate --version' works.
9576 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9578 2001-08-13 Akim Demaille <akim@epita.fr>

9635 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9637 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9639 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9640 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9641 * doc/autoconf.texi (C Compiler Characteristics): Update
9642 documentation for AC_C_BIGENDIAN.
9644 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9646 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9647 magic values from an object file when cross-compiling.
9648 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9650 2001-08-10 Akim Demaille <akim@epita.fr>
9652 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9653 effects.
9654 Suggested by Russ Allbery.
9656 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9658 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9659 current $prefix to the sub-configures.
9661 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9663 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9664 extension (needed on BeOS). Reported by Guido van Rossum.
9666 2001-08-09 Akim Demaille <akim@epita.fr>
9668 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9670 2001-08-07 Akim Demaille <akim@epita.fr>
9672 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9673 removed.
9674 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9675 No need to remove the files before and after the each test, before
9676 each test and at the end of the suite is enough.
9677 Display only the children `times', not the shell's.
9678 If the test failed or was skipped, at-times is not available.
9680 2001-08-07 Akim Demaille <akim@epita.fr>
9682 Always produce testsuite.log, including when there are no
9683 failures. This helps getting information on skipped tests, and
9684 duration of the tests. Err, implement the latter btw.
9686 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9687 Dump information on the first run of each test.
9688 (AT_CLEANUP): Create `at-times' containing the duration of the
9689 test group.
9691 2001-08-07 Akim Demaille <akim@epita.fr>
9693 The use of `dumpstat' revealed that `len' was used although it
9694 should not. m4_text_wrap was using it, but in the Autoconf world
9695 where it is legal. Hence (i) test M4sh in its own world, not
9696 Autoconf's, and (ii), ahem, fix the bug :)
9698 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9699 does not like `' instead of [].
9700 (AT_INIT): Forbid `^_?AT_'.
9701 And don't output such tokens.
9702 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9703 `script.as', and `autom4te.cache'.
9704 Remove `empty' and `macro' which are no longer used.
9705 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9706 * tests/m4sugar.at: Use it.
9707 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9709 2001-08-07 Akim Demaille <akim@epita.fr>
9711 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9713 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9715 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9717 2001-08-04 Akim Demaille <akim@epita.fr>
9719 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9720 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9721 AC_TRY_LINK.
9722 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9723 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9724 (AC_F77_MAIN): Likewise.
9726 2001-08-04 Akim Demaille <akim@epita.fr>
9728 Don't rely on M4sugar outputting the patterns in files, since we
9729 might process the output _without_ running m4, hence without these
9730 files.
9732 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9733 * bin/autom4te.in (@Request::includes): Remove, unused.
9734 (@Request::source): Rename as...
9735 (@Request::input): this.
9736 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9737 (&handle_output): Fetch the patterns from the traces.
9738 `$forbidden' and `$allowed' are constant: use m//o.
9739 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9740 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9742 2001-08-04 Akim Demaille <akim@epita.fr>
9744 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9745 autoconf', i.e., in addition to caching traces, cache the output.
9747 * bin/autom4te.in (Request::cache): Rename as...
9748 (Request::id): this.
9749 ($cache, $icache, $tcache, $ocache): New.
9750 (&handle_m4): Save M4 output in the cache instead of $tmp.
9751 (&handle_output): Adjust.
9752 (&up_to_date_p): Check that the output cache is up to date too.
9753 (top level): Run `&handle_m4' iff force or the cache is invalid.
9754 Run `&handle_output' if the output cache is more recent.
9756 2001-08-04 Akim Demaille <akim@epita.fr>
9758 * bin/autom4te.in ($force): New.
9759 (&parse_args, &print_usage): -f, --force is a new option.
9760 (&handle_output): CPP directives might have spaces after `#'.
9761 (&parse_args): The first file only can be frozen.
9763 2001-08-04 Akim Demaille <akim@epita.fr>
9765 Don't let autom4te compute the `include' traces several times:
9766 first check that the trace cache file is up to date, and then
9767 compare its timestamp with that of the output.
9769 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
9770 the preamble. Don't require 5.005 as Autom4te::General does it,
9771 and better yet (use `use', not `require'!).
9772 * lib/Autom4te/Struct.pm: Rename the last occurrences of
9773 Class::Struct as Autom4te::Struct.
9774 * lib/Autom4te/General.pm (File::stat): Use it.
9775 (&mtime): New, export it.
9776 * bin/autom4te.in: Use it.
9777 Declare `$req' is invalid if it is outdated.
9778 Don't declare it valid before saving it if something went wrong.
9780 2001-08-04 Akim Demaille <akim@epita.fr>
9782 Autom4te shall not encode Autoconf data, and preselecting traces
9783 must be proposed to the users.
9785 * bin/autom4te.in (@required_trace): Remove.
9786 (@preselect): New.
9787 (&parse_args, &print_usage): -p, --preselect is a new option.
9788 (&up_to_date_p): Adjust.
9789 * bin/autoconf.in: Preselect some Autoconf macros.
9791 2001-08-04 Akim Demaille <akim@epita.fr>
9793 * tests/tools.at (autoconf --trace: user macros): Check traces on
9794 macros invoked without arguments, and macros invoked with multiple
9795 lines arguments.
9797 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
9799 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
9800 arguments.
9802 2001-08-03 Akim Demaille <akim@epita.fr>
9804 * bin/autoconf.in ($@): Work around the usual sh bug.
9805 From Nicolas Joly.
9807 2001-08-03 Akim Demaille <akim@epita.fr>
9809 Clean up the handling of the M4 builtins tracing exception.
9811 * bin/autom4te.in (Request::request): Don't complete M4 builtins
9812 trace requests.
9813 (@m4_builtins): Rename as...
9814 (@m4_builtin): this.
9815 (%m4_builtin_alternate_name): New.
9816 (&parse_args): Complete the trace requests with alternate names.
9817 (&handle_traces): Hence no longer do it here.
9818 (&trace_requests): Remove, unused.
9820 2001-08-03 Akim Demaille <akim@epita.fr>
9822 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
9823 m4_if, and m4_wrap.

9828 (m4_divert_pop): Dump the whole diversion stack when a diversion
9829 mismatch happens.
9830 * bin/autom4te.in (&handle_output): Remember of the first
9831 occurrence of a possibly undefined macro, not the last.
9832 Complain about the possibly undefined macros in the same order as
9833 the appear in the output.
9834 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
9835 * tests/tools.at (autoconf: forbidden tokens, basic)
9836 (autoconf: forbidden tokens, exceptions): No longer sort
9837 autoconf's stderr, as it is now deterministic.
9838 Check that `dnl' is caught.
9840 2001-08-01 Akim Demaille <akim@epita.fr>
9842 * configure.ac: Bump to 2.52c.
9844 2001-08-01 Akim Demaille <akim@epita.fr>
9846 Version 2.52b.
9848 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.

9857 `die'.
9858 (&END): New.
9859 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
9860 `END', as `Autom4te::General::END' will be triggered.
9861 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
9862 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10254 compiler, not the preprocessor.
10255 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

10261 2001-07-03 Akim Demaille <akim@epita.fr>

10290 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
10291 dummy alternate main is required even if the user provides her own
10292 'main'.
10293 (AC_F77_MAIN): New macro to detect whether it is possible to
10294 provide an alternate 'main' function name, using the 'main' from
10295 the Fortran libraries.
10296 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
10297 cross-language link tests can be performed successfully.
10298 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10299 after $LIBS, for consistency; this should be the general rule since
10300 the user may want to link to Fortran libraries that require $FLIBS.
10301 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
10303 2001-06-29 Pavel Roskin <proski@gnu.org>
10305 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
10306 at-stdout and at-stderr instead of removing the newline
10307 from the echo output, which is not guaranteed to work.
10309 2001-06-28 Jens Petersen <petersen@redhat.com>
10311 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

10345 (&output_kind): here.
10346 (File::Basename): Use it.

10368 2001-06-23 Akim Demaille <akim@epita.fr>
