1 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4 that caused config.status to generate 100-command sed scripts; the
5 portable limit is 99.
7 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10 variable `ac_d' instead of `d' to avoid infringing namespace.
11 Report by Ralf Menzel.
13 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
15 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
16 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
17 * tests/tools.at (autoconf: subdirectories): New test, taken from
18 the corresponding problem report by Ralf Wildenhues in:
19 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
21 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
22 Quote some uses of shell variables if they might suffer unexpected
23 globbing. This doesn't fix all instances of quoting problems that
24 I found, just the easy ones that look safe.
25 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
26 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
27 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
28 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
29 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
30 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
31 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
32 Likewise.
33 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
34 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
36 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * bin/autoreconf.in ($help): Reword according to the manual.
39 Suggested by Olly Betts.
41 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
42 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
44 * bin/autoreconf.in: Pass the directory argument to
45 `require_configure_ac'. Fix comment.
46 * tests/torture.at (Configuring subdirectories): Expose this.
47 Reported by Olly Betts.
49 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
51 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
52 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
53 Automake as follows:
55 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
56 `$configure_in' instead of `configure.in', to preserve
57 directory component.
59 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
61 * config/config.guess, config/config.sub, config/texinfo.tex,
62 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
64 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
66 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
67 test for C99 conformance; (bool) 0.5 is an integer constant
68 expression, but (bool) -0.5 is not. Problem reported by Fedor
69 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
71 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
73 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
74 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
75 Warn about obsolete install-sh files. Remove stray sentence
76 fragment and fix cross reference.
77 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
78 install -d; this undoes the 2006-05-10 change.
79 (MKDIR_P): Mark with AN_MAKEVAR.
80 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
81 that we don't require $INSTALL to be thread-safe. Move comments
82 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
83 of AC_PROG_INSTALL. Output a message saying that we're checking
84 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
85 MKDIR_P instead of AC_SUBST.
86 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
87 Special magic for MKDIR_P, too.
88 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
89 a dnl.
90 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
92 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
94 Sync from Automake, as follows:
96 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
97 * config/install-sh: Initialize IFS, so field splitting isn't
98 turned off later.
99 * config/mkinstalldirs: Likewise.
100 * config/missing: Remove superfluous quotes. Replace all uses of
101 `[' by `test', for consistency, and for..
102 * config/missing (sed_minuso, sed_output): New variables.
103 (autom4te, help2man, makeinfo): Use them. Unifies detection of
104 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
105 Fixes `missing' to detect `--output' for help2man. Fixes
106 PR automake/483. Report by Dennis J. Linse.
107 (autom4te): Document in `missing --help'.
109 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
111 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
112 * config/install-sh: Don't use 'path' to talk about file names,
113 as per GNU coding standards. Close a race condition reported by Ralf
114 Wildenhues and Stepan Kasal. There is still a race condition
115 on hosts that predate Posix 1003.1-1992, but we can't help this.
116 Don't mishandle weird characters like space on pre-Posix hosts.
117 Invoke mkdir at most once per dir arg on pre-Posix hosts.
118 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
119 AC_PROG_MKDIR_P from AS_MKDIR_P.
120 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
121 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
122 earlier editions are not (including Automake 1.8.3).
123 Do not suggest mkinstalldirs for thread-safety.
124 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
125 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
126 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
127 presence of special characters and race conditions.
128 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
129 in Autoconf's name space.
131 2006-05-10 Bruno Haible <bruno@clisp.org>
132 and Paul Eggert <eggert@cs.ucla.edu>
134 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
135 from Automake with minor changes.
136 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
138 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
140 * config/install-sh: Update to Automake CVS version, as follows:
141 2006-04-25 Stepan Kasal <kasal@ucw.cz>
142 * lib/install-sh: Simplify the expr implementation of dirname.
143 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
144 * lib/install-sh: Handle --, and diagnose unknown options.
146 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
148 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
149 `./autom4te' to create `./testsuite', since the `all' target
150 will ensure its presence, but `installcheck' should not create
151 the uninstalled wrappers.
153 * tests/torture.at (Unusual Automake input files): Skip if we
154 detect automake < 1.8.
156 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
158 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
159 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
160 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
161 * NEWS: Update.
163 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
165 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
166 munge (multiple) white space and other oddities.
167 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
168 single quotes in variable assignment.
169 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
170 and similar failures by adding multiple spaces, tabs, and other
171 special characters.
172 Report and different test suggested by Francesco Romani
173 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
175 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
176 single quotes, we only need to search for single quotes; this
177 both simplifies the search pattern, and makes us less
178 susceptible to `echo' variations for arguments not containing
179 single quotes.
180 (_AC_ARG_VAR_VALIDATE): Likewise.
182 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
184 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
185 `$*' and IFS concatenation issue with traditional shells and
186 bash-2.04. Report by Seanster@Seanster.com.
188 2006-05-03 Bruno Haible <bruno@clisp.org>
190 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
191 precisely which Mac OS X versions have the od problem.
193 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
195 * doc/autoconf.texi: Use @option systematically.
196 (Integer Overflow):
198 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
199 and Bruno Haible <bruno@clisp.org>
201 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
202 about 'od'.
203 (Integer Overflow): Mention the special case of integer division
204 overflow.
206 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
208 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
209 traditional shells like the Solaris one that do not use the
210 first IFS character for assembling `$*'.
211 Prompted by a related report from autoconf_bug@nro.ca.
213 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
214 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
216 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
217 Mention more problems with the -e option.
219 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
221 * NEWS: Typo.
222 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
224 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
225 in URLs to improve DVI formatted output (requires texinfo 4.6).
226 (System Services, Systemology, Shellology): Likewise.
227 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
228 output.
230 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
231 continuous text.
232 (Runtime): Fix macro argument names to match description:
233 `action-if-found' -> `action-if-true' and similarly.
234 (Obsolete Macros): Likewise.
235 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
236 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
237 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
239 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
241 * doc/autoconf.texi (Limitations of Make): Clean up markup.
243 * ChangeLog: Typo.
244 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
245 DVI output.
247 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

257 (Integer Overflow, Null Pointers, Buffer Overruns):
258 (Floating Point Portability, Exiting Portably): New sections.
259 (Writing Test Programs): Fix some langauge. Recommend exiting
260 with status 1, not merely nonzero. Clarify exit declaration.
261 (Run Time): Move C exit status stuff to new Exiting Portably section.
262 (Systemology): Mention Posix and levenez. Update v7 reference.
263 (Portable Shell): Mention the Posix shell.
265 2006-04-25 Stepan Kasal <kasal@ucw.cz>
267 * bin/autoconf.as (me): Replace by as_me.
269 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
271 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
272 since as_me isn't set yet.
274 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
276 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
277 a few minor bugs in this area.
279 * doc/autoconf.texi (Programming in M4sh): Comment out the
280 documentation of AS_BASENAME, for now.
281 (Shell Substitutions): Do not use AS_DIRNAME in an example.
282 (Limitations of Builtins) <basename>: Do not refer to
283 AS_BASENAME.
284 * bin/autoconf.as (me): Don't use AS_BASENAME.
285 (dir): Remove the unused variable.
286 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
287 AS_DETECT_REQUIRED. All uses changed.

293 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
294 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
295 (_AS_DIRNAME_PREPARE): Likewise.
296 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
297 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
298 (AS_DIRNAME): Use "dirname --".
300 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
302 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
303 of "run time" and "run-time" changed to "runtime", for consistency.
304 * lib/autoconf/fortran.m4: Likewise (in comment).
305 * lib/autoconf/functions.m4: Likewise.
306 * lib/autoconf/general.m4: Likewise.
307 * lib/autoconf/headers.m4: Likewise.
309 * doc/autoconf.texi (Run Time): Document the exit status situation
310 with more accuracy and detail.
312 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
314 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
315 Archive is not officially `GNU' any more. Update URL.
316 (Defining Directories): Likewise
317 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
319 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
321 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
322 newline from the `trap' code to finish `config.log'; the NetBSD
323 /bin/sh resets the exit status after an empty command, as
324 documented in doc/autoconf.texi.
325 Reported by Dalibor Topic <robilad@kaffe.org>.
327 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
329 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
330 Suggested by Bruno Haible.
332 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
334 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
335 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
336 Instead, just list the shells that we know work.
337 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
338 changed. Be more cautious about the _cv_ variable.
339 * tests/tools.at (Syntax of the shell scripts): Check the
340 _cv_ variable once, at first, to avoid an internal autoconf error
341 when sh -n does not work.
343 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
345 * lib/Autom4te/FileUtils.pm: Sync from Automake.
347 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
349 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
350 use ">&-" since we're only 99.999% sure that this is portable,
351 and since the MinGW bug is fixed in a different way.
352 * lib/autotest/general.m4 (AT_INIT): Likewise.
354 2006-04-16 Stepan Kasal <kasal@ucw.cz>
356 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
357 before opening config.log, to avoid hitting a bug on MinGW.
359 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
361 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
362 AS_MESSAGE_LOG_FD before reopening it onto the log file.
363 This works around a MinGW bug reported by Eric Paire.
364 Make sure that all writes to the log file append to it,
365 rather than possibly losing data.
366 * lib/autotest/general.m4 (AT_INIT): Likewise.
368 2006-04-14 Stepan Kasal <kasal@ucw.cz>
370 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
371 description.
373 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
375 * NEWS: Update.
377 * configure.ac (AC_INIT): Bump to 2.59d.
379 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
381 Version 2.59c.
383 * Makefile.maint (news-date-check): Do not require a leading `*'
384 before the release date in NEWS.
386 2006-04-12 Stepan Kasal <kasal@ucw.cz>
387 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
389 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
390 the instantiated file do not contain the string 'datarootdir'
391 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
392 @mandir@, replace the reference '${datarootdir}' by the value.
393 * tests/torture.at (datarootdir workaround): New test.
394 * NEWS: Advertise this temporary fixup.
395 Based on a patch by Bruno Haible, reported and analyzed by
396 Paul Eggert and Noah Misch.
398 2006-04-12 Eric Blake <ebb9@byu.net>
400 * tests/autotest.at (Debugging a failed test): Fix comment.
402 2006-04-12 Stepan Kasal <kasal@ucw.cz>
404 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
405 all the changes since 2006-04-07.
407 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
409 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
410 succeeded, but `ln -s file dir' failed, take care to remove the
411 leftover target before the next test, to prevent its spurious
412 failure; also make sure `ln file dir' works before selecting it.
413 Thanks to Keith Marshall for pointing this out.
414 * THANKS: Update.
416 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
417 assignments in `at_debug_args', so that we put them correctly
418 in the `run' script.
419 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
420 Reported by Eric Blake.
422 2006-04-11 Eric Blake <ebb9@byu.net>
424 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
425 top-level tests after micro-suite has been run. Used in...
426 (Debugging a successful test, Debugging script and environment),
427 (Debugging a failed test): ...these new tests. The first of these
428 is fixed by...
429 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
430 macro, split out from...
431 (AT_INIT): ...here, so that using -d also generates a run script.
432 Document that -d inhibits top-level logging.
433 * doc/autoconf.texi (testsuite Invocation): Document that -d only
434 inhibits top-level logging; debug scripts are created.
436 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
437 check.
438 * tests/autotest.at (Empty test, Empty check): New test to check it.
440 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
441 from gcc.
443 2006-04-10 Stepan Kasal <kasal@ucw.cz>
445 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
446 the files if a problem appears. Make the empty *.at files
447 read-only, too. Proposed by Ralf Wildenhues.
449 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
451 * config/Makefile.am: Add comment to force updated Makefile.in.
453 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
454 space only patch to this file, this patch causes the Makefile.in
455 files that include freeze.mk to be updated, and thus have a
456 newer time stamp again, which in turn makes a pristine CVS
457 checkout have correct time stamps.
459 * Makefile.maint (cvs-sv): New macro, to be used..
460 (config.guess-url_prefix, config.sub-url_prefix)
461 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
462 point to CVS text checkout of Gnulib files.
463 (copyright-check): Bump current year.
464 (announcement): Do not hard-wire `./announce-gen'.
465 (cvs-update): Propagate failures of `cvs' and `move-if-change'
466 correctly.
467 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
468 `chmod +x'.
469 (wget_files): Update config.guess, config.sub, texinfo.tex by
470 `wget-update', now that their URLs work again.
472 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
474 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
475 Problem noted by Paul D. Smith.
477 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
479 * doc/autoconf.texi: Remove unused words from word list.
480 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
481 .x-sc_trailing_space: New files.
483 * doc/standards.texi: Sync from gnulib.
485 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
486 `LIBOBJDIR' as experimental.
488 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
489 with a target directory; it's internally implemented as `cp'
490 anyway, but since Autoconf advertises the possibility to use
491 a target directory when LN_S is `ln -s', we need to find out.
492 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
493 analyzed by Keith Marshall <keith.marshall@total.com>.
495 * THANKS: Update.
497 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
499 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
500 confdefs.h as-is. In general, if it has backslash-newline or the
501 like, then it doesn't work either to sort or to remove empty
502 lines.
504 2006-04-09 Stepan Kasal <kasal@ucw.cz>
506 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.

510 * lib/autom4te.in (Automake-preselections): Preselect
511 _AM_SUBST_NOTMAKE.
513 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
515 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
516 apostrophe within a single-quoted string, as this is the usual
517 tradition and is easier to read than '"'"'. Don't rely on the
518 shell treating "$/" like '$/'. Use a more-consistent indenting
519 style for the trap.
521 2006-04-09 Eric Blake <ebb9@byu.net>
523 * tests/autotest.at (Backquote command substitution),
524 (Multiline backquote command substitution): Remove mistaken
525 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
526 applied...
527 (Parenthetical command substitution, Multiline parenthetical
528 command substitution): here.
530 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

563 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
564 (C Compiler): Move AC_C_LONG_DOUBLE to ...
565 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
566 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

594 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
595 of the warning introduced by the 2001-08-28 change.
597 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
598 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
600 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
601 variables shall be overriden by the cache.

603 that contains braces.
605 2006-04-07 Stepan Kasal <kasal@ucw.cz>
607 Revert the patch from 2006-04-01 and only improve
608 _AS_DETECT_BETTER_SHELL:
610 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
611 skip nonexistent directories.
612 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
613 only shell candidates which exist.
614 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
615 * lib/autotest/general.m4 (AT_INIT): No need to give three
616 parameters to _AS_PATH_WALK.
618 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
619 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
621 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
622 distinguish m4sugar macros.
623 * tests/tools.at (autoupdating with aclocal and m4_include):
624 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
625 test case by Noah Misch <noah@cs.caltech.edu>.
627 2006-04-07 Stepan Kasal <kasal@ucw.cz>
629 Revert my change from 2006-03-17, in other words:
630 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
631 and DUALCASE=1.
632 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
633 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
634 it is set.
636 2006-04-07 Eric Blake <ebb9@byu.net>
638 * doc/autoconf.texi (Programming in M4sh): Document that
639 AS_MKDIR_P exits the script on failure.
640 * lib/autotest/general.m4: Remove redundant AS_ERROR.
642 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
644 * config/elisp-comp, config/install-sh, config/mdate-sh,
645 config/missing, config/mkinstalldirs: Sync from Automake.
647 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync

659 Eric Blake <ebb9@byu.net>,
660 Paul Eggert <eggert@cs.ucla.edu>,
661 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
663 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
664 whether `set' quotes correctly: redirect stderr of the tested
665 `set', and use a subshell, for Ultrix; use `sed' instead of
666 `grep' for zsh `set' which may write binary output; match only
667 at the beginning of a line, to avoid false positives.
668 In order to avoid false positives by unrelated variables with
669 multiline content, put the dump algorithm in a subshell and
670 unset all variables containing newlines (except some which are
671 special to the shell). Warn about cache variables that are
672 unset.
674 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
676 * config/config.guess, config/config.sub, config/texinfo.tex:

685 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
686 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
687 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
688 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
690 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
691 shell issue with double-quoted command substitutions of native
692 commands.
693 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
694 Marshall.
696 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
697 no file matches the glob, discard the warning, set `nullglob'.

703 (sc_system_h_headers): Do not print rule on execution.
704 (sc_tight_scope): Do not fail for non-existing `src' directory.
705 (sc_changelog): Skip the Copyright footer.
706 * lib/autoconf/lang.m4: Remove trailing space.
708 * lib/autoconf/status.m4: More replacements to
709 <tab><space> where this makes sense.

714 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
716 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
717 ac_config_<foo>s again, sometimes normalized, sometimes not.
718 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
719 (AC_CONFIG_COMMANDS): Do not do so here.
720 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
721 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
722 2005-07-25 rewrite. Noticed by Noah Misch.
724 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
725 _AC_PRESERVE_HELP_ORDER, ...
726 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
728 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
729 inside m4_expand_once; it is redundant.
731 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
732 for --help from Cygnus `configure.'
734 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
736 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
737 on a patch proposed by Ralf Wildenhues.

745 Noah Misch <noah@cs.caltech.edu>
747 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
748 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
749 * doc/autoconf.texi (Help Formatting): New node.
750 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
752 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
754 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
755 lib/autoconf/specific.m4, lib/autoconf/status.m4,
756 lib/autoconf/types.m4, lib/autotest/general.m4,
757 tests/mktests.sh, tests/torture.at: White space cleanup:
758 remove some SPACE before TAB, or add quoting ('' or @&t@).
760 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
762 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
764 2006-04-05 Eric Blake <ebb9@byu.net>
766 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
767 empty test suite works.
768 * tests/autotest.at (Empty test suite): Remove xfail.
770 2006-04-05 Noah Misch <noah@cs.caltech.edu>

774 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
775 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
776 normalizing it, consistent it with previous releases.
777 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
779 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
781 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
782 Use simplified args that Eric Blake originally suggested.
784 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
786 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
787 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
788 Use 'comm' rather than N instances of grep; this also fixes a bug
789 whereby substrings were incorrectly matched, causing us to not
790 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
791 (exclude_list): Exclude empty macros.
792 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

808 report request when we have no AC_PACKAGE_BUGREPORT.
810 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
812 * THANKS: Update.
814 * tests/mktests.sh: Update copyright year in the header of the
815 generated files.
817 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
818 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
819 typedef'ed restricted pointer, to catch a compiler bug on

840 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
842 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
843 to log, point to testsuite output tree.
845 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
847 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
848 * doc/autoconf.texi (Function Portability): Mention that C++
849 has trouble with 'exit'.

873 Clean up _AC_COMPILER_EXEEXT* macros.
875 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
876 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
877 ac_file to the name of the default output filei and call
878 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
879 initial `rm' of the candidate files...
880 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
881 the same list in subsequent `rm' calls, and for the temporary
882 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
883 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
884 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
885 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
886 no longer needed) by libtool. Make it a cache check.
887 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
888 copied here by mistake.
889 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
890 _AC_COMPILER_EXEEXT.
891 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

1664 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1665 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1666 by the function rather than ignoring it.
1667 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1668 comparing its address. Intel's interprocedural optimization was
1669 outsmarting the old heuristic. Problem reported by

1687 Stepan Kasal <kasal@ucw.cz>
1689 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1690 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1691 make its content writable before removing it. Remove an errorneous
1692 comment from the end, where the logs of the failed tests are copied
1693 to the main log file.
1695 2005-09-27 Stepan Kasal <kasal@ucw.cz>

1702 problems if the testsuite were running too fast.
1704 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1706 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

1718 suggested by Ben Elliston. Handle weird characters correctly.
1720 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1722 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1723 calls, so that the final expansion of this macro is shorter.
1724 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1725 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1726 the cleanup there. Use AS_VAR_* macros, to be more general.
1727 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1729 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1731 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

1746 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1747 The previous patch didn't work, so try a better one.
1749 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1751 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1752 in the example. Reported by Bruno Haible.
1753 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1754 "if $undefined_var;" succeeds with my shell.
1756 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1757 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1758 but change the m4_divert_text to m4_divert_once.

1762 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

1768 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
1769 some evil values and relying on the fact that $* concatenates the
1770 parameters by the first character from IFS.

1773 Stepan Kasal <kasal@ucw.cz>
1775 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
1776 first header appears, define AH_HEADER.
1777 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1778 Update limitations about when to call AC_CONFIG_HEADERS.
1779 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1780 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1781 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1782 ``Configuration Actions''; fix their index entries.
1784 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1785 options correctly. Process N-M as M-N if M is smaller than N.
1786 Process ranges correctly so that N-N will run only N.
1787 Sort and uniquify the tests that will be run. If there is more
1788 than one test, reinsert the banners for the tests.

1794 before passing the macro name to AH_TEMPLATE.
1796 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1797 now opens log after option processing; in particular, --version
1798 and --help do not touch config.log.

1815 Prepend to LIBS, not append, in examples.
1817 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1819 When building in place, set srcdir="."; suggested by Tim Van Holder.
1821 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1822 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1823 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1824 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

1836 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1838 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1839 add "2>&1"; gzip 1.2.4 prints help on stderr.
1841 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1843 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1844 was pushdef'ed twice while popped only once. Push it only once.

1861 Rewrite substantial part of lib/autoconf/status.m4.
1862 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1863 and CONFIG_COMMANDS are not processed in four separate loops.
1864 Instead, there is one main loop. This alows that the common code
1865 is expanded only once, thus config.status (and configure) is smaller.
1867 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1868 the AC_LIST_FILES and cousins macros are no longer used.
1870 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1871 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1872 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1873 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1874 contain the initialization, nor the for loop, nor the associated
1875 commands; all these go to ...
1876 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1877 _AC_OUTPUT_CONFIG_STATUS.
1878 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1879 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1880 (_AC_OUTPUT_FILE): The creation of the sed script ...
1881 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1882 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1883 _AC_OUTPUT_MAIN_LOOP.
1884 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1885 _AC_CONFIG_COMMANDS): Use ...
1886 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1887 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1888 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1889 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1890 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1891 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1892 ... new macros.
1893 (_AC_CONFIG_UNIQUE): Update.
1894 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1895 Replaced by this ...
1896 (_AC_LIST_TAGS): ... new common macro.
1897 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1898 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1899 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1900 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1901 this didn't belong to the `config commands' section.
1902 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1903 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1904 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1905 to the `config commands' section either.
1906 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1907 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1909 ... and many changes to the comments nearby.
1911 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1912 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1913 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1914 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1915 (#define header templates): The comment at the top of the generated
1916 header now includes the name(s) of the source file(s).
1918 Several unrelated small changes:
1920 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1921 parameter to AC_DIAGNOSE.
1922 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1923 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1924 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1925 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1926 with AU::AC_OUTPUT.
1927 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
1928 in AC_OUTPUT doesn't double-quote it either.
1929 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
1930 parameters.
1932 2005-07-10 Stepan Kasal <kasal@ucw.cz>
1934 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
1935 versions of Portland Group compiler produce single- and double-quoted
1936 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>

1954 change eliminates it. Problem reported by Alexandre Duret-Lutz.
1955 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
1956 (AC_ARG_VAR): ... here.
1957 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
1958 target_alias.
1960 Keep a list of all precious variables and process them with one simple
1961 for loop, instead of expanding all commands, or, OTOH, complicated
1962 processing of output of "set".
1963 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
1964 variable names in new macro...
1965 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
1966 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
1967 a loop to assign all ac_env_* and ac_cv_env_* variables.
1968 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
1969 to INIT_PREPARE.
1970 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
1971 its value to shell variable ac_precious_vars and call
1972 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
1973 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
1974 _AC_ARG_VAR_VALIDATE.
1976 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

1993 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
1994 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1995 They are generated by the Tru64 v5.1B shell.
1997 2005-07-05 Stepan Kasal <kasal@ucw.cz>
1999 Fix my changes from 2005-07-01; reported by Noah Misch.
2000 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2001 description, the macro now accepts only a single tag.
2002 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2004 Fix cases when the varsions of Autoconf and Autotest don't match.

2007 at_top_builddir, for compatibility with older autotest.
2008 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2009 is not set, use at_top_builddir, for compatibility with older
2010 versions of autoconf.
2012 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2014 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

2019 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2020 sed substitution command, so that we allow | in program prefixes
2021 and program suffixes. (& is a problem anyway; we're not fixing
2022 that here.)
2023 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2024 configure_input, top_builddir, srcdir, etc.
2025 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2026 PATH_SEPARATOR in AUTOTEST_PATH.
2028 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2030 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

2036 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2037 directories with weird names. Apparently some people like living

2059 document to output the default config_* lists to config.status.
2060 Don't recognize option --file, if the functionality is not there.
2061 Likewise for --header; moreover, recognize --he and --h as shortcuts
2062 for --help in that case.
2064 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2065 matches the order of execution. No code changed.

2087 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2088 (AC_SUBST): Call it.
2089 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2090 the directory specific variables; but don't call it for configure_input.
2092 2005-06-28 Derek Price <derek@ximbiot.com>
2094 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2095 addition.
2097 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2099 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2100 directory have inherent problems with special characters like spaces,
2101 due to limitations in Make syntax. Problem reported by Alexandre
2102 Duret-Lutz.
2103 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

2118 variable into diagnostic. Make the diagnostic an error, not a warning,
2119 because we really don't support spaces and suchlike in dir names.
2120 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2121 Don't worry about backslashes in srcdir; it can't happen now.

2138 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2140 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2148 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2149 b, t, r, w commands require single space, while : cannot have any.
2150 (Special Shell Variables): Fix sed code this in the example.
2151 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2152 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2154 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2155 expand to the empty list. Don't use two pairs of m4_changequote,
2156 it's not necessary.
2158 2005-06-20 Derek Price <derek@ximbiot.com>
2160 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2162 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2164 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2165 * doc/autoconf.texi:
2166 Don't mention Solaris versions so much, if a
2167 problem is common to all extant versions of Solaris. Say "SunOS
2168 4" instead of "SunOS" for SunOS 4.
2169 (awk): Mention more of the limitations of traditional Awk.
2170 (cat): Don't talk about cat -v.
2172 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

2183 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2184 Use shell builtins rather than 'expr', to work around expr bug.
2186 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2188 * doc/autoconf.texi: "filesystem" -> "file system".
2189 "behaviour" -> "behavior".

2202 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2203 quotes and backslashes. Patch from Derek Price.

2212 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2213 -u, since it outputs chatter if the input files are the same.
2214 Problem reported by Ralf Menzel.
2216 2005-06-08 Derek Price <derek@ximbiot.com>
2218 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2219 renaming them since they are about to be redefined anyhow.
2221 2005-06-08 Derek Price <derek@ximbiot.com>
2223 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2224 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2225 Move m4_undefine to alphabetical order.
2227 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2229 * README: Recommend GNU M4 1.4.3 or later.
2230 * doc/autoconf.texi (Introduction): Likewise.
2231 Reword to avoid some formatting glitches.
2232 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2233 Clarify explanation of HP compiler bug.
2234 Redo example output tp match current CVS snapshot.
2235 Use @example.org in email addresses when the examples
2236 might get inadvertently cut-and-pasted into user code.
2237 Remove example of autom4te usage that doesn't seem to work now.
2238 Use modern AC_INIT (except when the example is meant to be
2239 shown with Autoconf 2.13).
2240 Update ksh info for Solaris 9 and later.
2241 KB -> kB.
2242 Modernize description of Automake versions a bit.
2243 Don't claim a future version of Autoconf is near.

2249 follows its own advice about quoting better.
2250 Reword to avoid some formatting glitches.
2251 * doc/installt.exi: Reword to avoid some formatting glitches.
2253 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2254 Tru64 ksh pattern matching bug. Reported against Libtool by
2255 Albert Chin <libtool@mlists.thewrittenword.com> and
2256 Nicolas Joly <njoly@pasteur.fr>.
2258 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2260 m4_cdr of one-member list was [[]] (one-member list containing an
2261 empty string) instead of [] (an empty list. Callers were skewed to
2262 match this misbehaviour. As a consequence of this:
2263 - m4_foreach([x], [], [foo]) expanded to `foo', while
2264 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2265 This bug has been fixed:
2267 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2268 expand to an empty string; print error msg if called without
2269 an argument list.
2270 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2271 misbehaviour; handle [] and [[]] correctly.

2275 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
2276 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
2277 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2279 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2281 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2282 swallow records with more than 99 fields.
2283 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2284 parse the long line.
2286 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2288 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2289 swallow literals longer than 399. Reported by Ralf Wildenhues.
2290 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2291 to workaround this limitation.
2293 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2295 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2296 to gfortran, and make these the first two compiler names
2297 checked (following the general autoconf preference for gcc).
2299 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2301 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2302 (DISTCLEANFILES): Remove $(check_SCRIPTS).

2307 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2308 expression of unbounded size when processing the --list
2309 option. This runs afoul of a limit of 399 bytes per regular
2310 expression on AIX. Problem reported by Ralf Wildenhues.
2312 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2314 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2315 * doc/autoconf.texi (Particular Headers): Reword example
2316 for multiline stdbool replacement.
2317 (Setting Output Variables): Reword text a bit. Don't
2318 give all the details about |#_!!_#|.
2319 Reword description of line replacement.
2321 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2323 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2324 now contain newlines, and substituted files must be referenced on
2325 a line alone; the sed scripts to substitute them are now very
2326 different.
2327 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2328 commands can be put in a sed script portably.
2329 * doc/autoconf.texi (Setting Output Variables): Document above
2330 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2331 use of multiline substitution.
2332 * tests/torture.at: No longer expect substitution of newline to fail.
2334 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2336 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
2337 From Ralf Menzel (trivial change).
2339 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2341 * tests/local.at: Don't attempt to check for negated character
2342 classes in shell scripts. The test was too brittle.
2344 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2346 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2347 * doc/autoconf.texi (Limitations of Builtins): Document this
2348 limitation.
2350 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2352 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2353 common code; used in many places in the tree.
2354 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
2355 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2357 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2359 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2360 messages when ac_unique_file is not found.
2361 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2362 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2363 commands, for consistency with AC_MSG_ERROR and such.
2365 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2367 * bin/Makefile.am: Merge the two rules for creating scripts.
2369 2005-05-23 Stepan Kasal <kasal@ucw.cz>
2371 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
2372 obsolete; it was never documented.
2373 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2375 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2377 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2378 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2379 (ac_top_builddir): ... this ...
2380 (ac_top_build_prefix): ... to this; the old name is also kept, for
2381 backward compatibility.
2382 (ac_top_builddir_sub): New variable, without the trailing slash,
2383 always nonempty.
2384 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2385 * doc/autoconf.texi (Configuration Actions): Rename
2386 ac_top_builddir to ac_top_build_prefix.
2387 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2388 at_top_builddir to at_top_build_prefix.
2389 * lib/autotest/general.m4 (AT_INIT): Likewise.
2391 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2393 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2394 of confdefs.h .
2396 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2398 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2399 argument to m4_foreach. I guess it was necessary in the past,
2400 but I think it's a no-op now.
2402 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2404 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2405 ``cat <<_ACEOF'' commands to one.
2406 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2407 * lib/autoconf/status.m4: On various places, use expr instead of
2408 ``echo|sed.''
2409 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2410 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2411 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2412 a range.
2413 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2414 the wrong patterns between ``case'' and ``esac.'' The previous
2415 code had false positives.
2417 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2419 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2420 as on 2005-05-02.
2421 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2422 Mention LIBOBJDIR.

2462 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2464 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2465 check.
2466 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2467 enough arguments, similarly as in m4_bpatsubsts.
2469 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2471 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2472 of absolute paths.
2474 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2476 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2477 for absolute directory names in one loop.
2478 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2479 abbreviations of --version and --debug.
2481 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2483 * doc/autoconf.texi (Autoconf Language): Be more precise about
2484 quoting rules. Problems noted by Stepan Kasal.
2485 Also, throughout this document, be more careful about white space.
2486 "blank", "white space", and "space" all have different meanings
2487 and we should be careful to say what we mean.
2489 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2491 Fix C++ related problems reported by Werner Lemberg.
2492 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2493 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2494 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2495 avoid problems with C++ and throw.
2496 * tests/compile.at: .cpp, not .cc.
2498 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2500 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2502 * doc/autoconf.texi (Generic Functions): Typos.
2504 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2506 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2507 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2508 set by latest automake.
2510 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2512 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2513 outputs 0 on GNU/Linux these days.
2515 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2517 * doc/autoconf.texi (Autoconf Language): Add more description
2518 about quoting heuristics.
2519 (Limitations of Builtins): Describe "set -" problems.
2521 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2523 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2524 not newline.
2526 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2527 by AC_DEFINE; it was a mistake.
2528 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2530 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2532 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2534 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2536 * doc/autoconf.texi (External Software): Quadrigraphs are not
2537 processed correctly in AS_HELP_STRING; avoid this in the examples.
2538 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2539 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2540 comment and reduce m4_default([foo], []) to [foo].
2541 (m4_strip): Update the explanation.
2543 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2545 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2546 Remove core.conftest.* too; it's generated by Tru64 5.1.
2547 Problem reported by Jennis Pruett.
2548 * lib/autoconf/functions.m4
2549 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2550 Don't bother to remove core files; AC_RUN_IFELSE should do that
2551 for you.
2553 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2555 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2557 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

2562 2005-04-15 Stepan Kasal <kasal@ucw.cz>
2564 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
2565 the comment.
2567 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
2569 * doc/autoconf.texi (External Software, Package Options): Add
2570 examples showing how to implement --with-* and --enable-* options.
2572 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2574 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2575 as well as configure.in. Problem reported by Gregorio Guidi.
2577 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2579 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2580 pattern for alloca snippet.

2590 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2592 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2593 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2595 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2597 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2598 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2599 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2600 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2601 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2603 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2605 * NEWS: The configure command now warns you if you attempt to use
2606 a directory whose name contains a special character like space,
2607 newline, or "\".
2608 * doc/autoconf.texi (Installation Directory Variables): Allow
2609 "," in file names. Do not use \@; it's not a portable regexp.
2610 * bin/Makefile.am (edit): Likewise.
2611 * lib/Makefile.am (edit): Likewise.
2612 * tests/Makefile.am (edit): Likewise.
2613 * tests/semantics.at: Likewise.
2614 * tests/torture.at: Likewise.
2615 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2616 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2617 * doc/autoconf.texi (File System Conventions): Warn about
2618 unportable file names.
2619 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2620 (AC_INIT): Use it.
2621 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2622 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2623 ac_pwd, and quote srcdir.
2624 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2626 * doc/autoconf.texi: Fix some systematic formatting problems.
2627 ".)" needs a following @: if not at the end of a sentence, and
2628 similarly for "!)". "etc." should be preceded by a comma.
2629 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2631 2005-03-22 Bruno Haible <bruno@clisp.org>
2633 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2634 argument is often called 'build-aux'.
2636 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2638 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2639 macro AC_TRY_LINK is obsolete.
2640 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2641 `AC_CONFIG_FILES'.
2643 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2645 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2646 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2647 from a Common Lisp's `cl'.
2648 (AC_PROG_CXX): Behave according to the documentation: don't
2649 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2650 make the variable CCC precious; use `cl.exe', not `cl'.
2652 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2653 Alexandre Duret-Lutz <adl@gnu.org>
2655 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2656 /dev/null, as "configure" shouldn't read stdin, and this insulates
2657 us from problems (e.g., when testing for "cl"). Also, do this
2658 redirection before invoking "hostname" or "uname", and keep the
2659 original input stream available via...
2660 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2661 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2662 bother with "</dev/null" since it's now done at the top of
2663 'configure'.
2664 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2665 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2666 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2667 * doc/autoconf.texi (File Descriptor Macros): New section.
2668 (Printing Messages): Mention it.
2669 * tests/base.at (Input/Output): New test.
2671 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2673 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2674 newline if neither \c nor -n work, as that would output two
2675 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2677 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2679 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2680 This causes that any required macros inside will get before the if.
2681 * doc/autoconf.texi (autom4te.cache): A typo.
2683 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2685 Undo previous change, except keep the change to
2686 lib/autoconf/programs.m4 that replaced grep with shell
2687 pattern-matching. This is because net-snmp configure reads stdin.
2688 Reported by Noah Misch.
2690 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2692 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2693 from /dev/null, as "configure" shouldn't read stdin, and this
2694 insulates us from problems (e.g., when testing for "cl").
2695 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2696 before invoking "hostname" or "uname".
2697 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2698 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2699 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2700 "</dev/null" since it's now done at the top of 'configure'.
2701 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2702 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2703 Also, replace grep with shell pattern-matching, to save a process.
2705 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2707 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2708 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2709 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2710 compiler.
2712 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2714 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2715 grep -q isn't portable. Improve grep -s explanation.
2716 Problem reported by Dan Manthey.
2718 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2720 * doc/autoconf.texi (Special Shell Variables): Clarify
2721 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2723 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2725 * doc/autoconf.texi: Use @acronym for DJGPP.
2726 Fix some @code's that should have been @env's, and vice versa.
2727 Sort environment variable names.
2728 Mention that shells no longer inherit IFS.
2729 Don't recommend PATH_SEPARATOR=';' so strongly.
2730 Mention that $RANDOM might expand to the empty string.
2731 "symlink" and "soft link" -> "symbolic link".
2732 Improve mktemp description (reported by Bruno Haible).
2734 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2736 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2737 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2738 Likewise.
2739 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2740 Likewise.
2742 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2744 * NEWS: Mention AT_COPYRIGHT.

2808 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2810 Try not to generated lines of unlimited length, as POSIX places a
2811 2047-byte limit on line length of portable text files.
2812 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2813 Use newline as a separator, not space.

2871 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2872 Update the long comment explaining it.
2874 m4_require no longer writes an ``is required by'' line to the
2875 execution stack. It contains only one bit of non-redundant
2876 information: that the macro was required, not called. And even
2877 this bit is useless in most situations: have you ever met a macro
2878 which both calls and requires the same macro?
2880 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2881 (_m4_defun_pro_outer): ... only via this macro, for the outermost

2888 (_m4_require_call): Use it.
2889 * tests/m4sugar.at (m4_require): Expect output without the
2890 ``is required by'' messages.
2892 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2894 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2895 rather than x for expr.
2897 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2898 this is safe.
2899 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2900 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2913 support.
2914 * bin/autoheader.in: Pass $force to update_file so that
2915 config.h.in is always recreated when --force.

2921 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2923 * doc/autoconf.texi (Limitations of Builtins): Clarify that

2926 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2928 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2929 Warn about newline stripping in `` and $(). Update Solaris
2930 version to 9.
2931 (Limitations of Builtins): Use expr "X...", not expr "x...", as
2932 X insulates us from future changes to Posix.
2933 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
2934 stripping.
2936 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2956 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
2958 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2960 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

2982 (_m4_divert_n_stack): New macro; the expansion is
2983 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
2984 otherwise.
2985 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
2986 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
2987 stored in _m4_divert_diversion or _m4_divert_dump.
2988 (m4_divert_pop): When the parameter is given, compare the symbolic
2989 name with the last diversion pushed on the stack. Previously, the
2990 current diversion was compared with the numeric value of the
2991 diversion given as the parameter.
2992 (m4_require): If the macro hasn't been expanded yet, call ...
2993 (_m4_require_call): this new macro.

3026 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3272 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3274 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
3275 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
3276 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
3277 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

3296 with exactly one parameter.
3298 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3300 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3301 "char c = '\200';" rather than "char c = 0x80;" as the
3302 latter doesn't conform to the strict C standard due to
3303 overflow on signed char hosts.
3305 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3306 to -qlanglvl=ansi. We don't want to disable extensions.

3328 * BUGS: Don't mention bugs.gnu.org.
3329 Remove mention of ancient libtool compatibility problem.
3330 * NEWS: Mention that bugs.gnu.org is kaput.

3365 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3367 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3368 the $1_found variable, don't test whether the file is executable;
3369 Both things are checked ...
3370 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3371 the former ``test -f''.
3372 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
3374 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

3384 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3386 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

3406 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3407 Problem reported by Stepan Kasal.
3409 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3411 Fix problems reported by Andreas Buening in:
3412 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3413 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3414 in test makefile.
3415 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3416 readable; it's not true in OS/2-emx.
3418 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3420 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3421 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3422 (trivial change). Problem and patch reported by Andrew Church in:
3423 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3425 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
3427 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

3452 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3453 texinfo.tex for now (done by hand now).
3454 * Makefile.maint (wget_files, cvs_files):
3455 Remove ansi2knr.c; nobody uses it.
3456 (ansi2knr.c-url_prefix): Remove.
3457 (cvs-update): Fix test for failure. I don't know why it ever
3458 worked...
3460 * doc/autoconf.texi: Update URLs, some of which went stale.
3461 Use @uref rather than @href.
3463 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3464 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3466 * config/config.guess, config/config.sub, config/elisp-comp,
3467 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3468 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3470 * NEWS, TODO, configure.ac, bin/autoscan.in,
3471 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3472 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3476 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3477 tests/tools.at, tests/torture.at:
3478 Use "file name" rather than "filename" or "path",
3479 to be consistent with the terminology of the GNU coding standards.
3481 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3483 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3484 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3485 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3486 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3488 More fixes to support spaces in the name of the build directory.
3489 This isn't a complete fix but it's an improvement.
3491 * bin/autoconf.as (autom4te_options): New var.
3492 Use it instead of appending to AUTOM4TE, so that we can allow
3493 spaces in the build directory's absolute name.
3494 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3495 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

3497 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3498 main program): Likewise.
3500 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3502 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
3503 From Ralf Corsepius in:
3504 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
3506 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3508 * doc/autoconf.texi (Function Portability): Document isinf and
3509 and isnan. From a suggestion by Kevin Ryde.
3511 * lib/Autom4te/General.pm (END): Return correct exit status even
3512 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3514 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3516 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3517 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3518 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3520 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3522 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3523 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3524 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3525 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3526 * lib/autom4te.in (Automake-preselections): Preselect
3527 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3529 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3531 * lib/autom4te.in (Automake-preselections): Preselect
3532 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3533 trace them.
3535 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3537 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3538 Tru64.
3539 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3540 Document problem with "`""`" in pdksh POSIX mode.
3542 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3544 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3545 with pdksh, too. Problem reported by Patrick Welche via
3546 Gary V. Vaughan.
3547 * doc/autoconf.texi (Shellology): Note that set -o posix is
3548 useful for pkdsh, too.
3550 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3552 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3553 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3554 Don't fail if ENV or BASH_ENV is readonly.
3555 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3556 etc. are read only. Problem reported by Ludovic Courtes.
3558 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3560 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

3562 (trivial change)
3564 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3566 * doc/autoconf.texi (File System Conventions): Warn about
3567 names like "aux". Problem reported by Eric Blake.
3569 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3570 by zero instead of array size, so that we can use any arithmetic
3571 constant expression (instead of requiring an integer constant
3572 expression). This allows us to test expressions like DBL_MAX <
3573 LDBL_MAX, which didn't conform to the C standard using the old
3574 method.
3575 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3576 now that we can do floating-point tests at compile time.
3578 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3580 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3581 and LDBL_EPSILON, as the resulting expression isn't an
3582 integer constant expression and violates the C standard.
3583 Problem reported by Nelson H. F. Beebe. Also, check
3584 for "L" suffix, and check that long double doesn't have
3585 worse range or precision than double, that mixed-mode
3586 arithmetic doesn't generate a diagnostic, that double
3587 constants fit in long double.
3589 2004-06-03 Kevin Ryde <user42@zip.com.au>
3591 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3592 malloc(0) and realloc(NULL,size).
3594 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3595 Bob Proulx.
3597 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3599 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3600 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3601 by Jim Meyering.
3603 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3605 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3606 can be rewritten using if-then-else. Suggested by Bruno Haible.
3608 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3610 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3611 Problem reported by Stepan Kasal.
3613 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3615 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3616 change). Patch reported by Ralf Wildenhues in
3617 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3619 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3620 function F exists if the compiler and linker let you compile an
3621 expression like (F != 0). Recent versions of GCC optimize away
3622 the reference to F in that case, since every function address must
3623 be nonzero, so the link succeeds even if F does not exist.
3624 Problem reported by Manu in
3625 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3627 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3628 "Unix". Many uses changed.
3629 (Limitations of Builtins): Explain better why the ! command isn't
3630 portable.
3632 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3634 * lib/autom4te.in (Automake-preselections): Preselect
3635 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3637 2004-05-19 Kevin Ryde <user42@zip.com.au>
3639 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3640 referencing AC_FUNC_STRERROR_R.
3642 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3643 note pessimistic assumption when cross compiling.
3645 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3647 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3648 (until 2004) invoked subcommands with sh -e, contra POSIX.
3649 Reported by Kevin Ryde.
3651 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3653 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3654 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3655 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3656 `test -f " /usr/bin/grep"', which _always_ failed.
3657 (AC_PROG_SED): Ditto bogus PATH fix.
3658 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3659 requires that grep correctly supports _multiple_ `-e' options, rather
3660 than stating only that grep should accept `-e'.
3662 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3664 Port to C99, which requires that 'exit' be declared.
3666 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3667 to ensure that stdlib.h is included.
3668 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3669 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3670 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3671 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3672 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3673 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3674 when using 'exit' in a test; C99 requires that 'exit' be declared.
3676 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3678 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3679 now prefers 'grep' implementations that accept -e.
3680 (Limitations of Usual Tools): Describe problems of traditional
3681 egrep and fgrep with long input lines, and of traditional grep
3682 with -e.
3683 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3684 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3685 All callers changed. Append /usr/xpg4/bin to the PATH, for
3686 Solaris.
3687 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3688 the user with complaints about multiple -e options.
3689 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3690 Define it with AC_PROG_GREP.
3691 * configure.ac (AC_PROG_GREP): Add.
3692 * lib/freeze.mk (GREP): New macro.
3694 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3696 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3697 a possible candidate only after all others fail, rather than
3698 consulting it first. This improves backward compatibility by
3699 better reflecting the way shell selection occurred in previous
3700 versions of Autoconf, and should help to avoid triggering latent
3701 problems in other packages, such as the one in Automake where zsh
3702 is not handled robustly:
3703 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3704 Although it is not Autoconf's responsibility to work around
3705 problems in Automake, it nevertheless makes sense to avoid
3706 introducing unnecessary incompatibilites.
3708 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3709 Gary V. Vaughan <gary@gnu.org>
3711 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3712 how deeply nested we are when a suitable tool is found, set the
3713 ac_path_TOOL_found flag.
3714 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3715 nested we are in this macro. Break out of all 3 nested loops if
3716 ac_path_TOOL_found is set.
3718 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3720 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3721 of the _AS_PATH_WALK loop too if GNU flavor is found.
3723 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3725 * doc/autoconf.texi (Limitations of Make): Update documentation
3726 for `$<'. New entry `Long lines', based on a report from Simon
3727 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3728 paragraph about DJGPP, based on a mail from Richard Dawe.
3730 2004-04-20 Paul Eggert <eggert@twinsun.com>
3732 * tests/c.at (C keywords): Don't assume that GCC supports
3733 "restrict" and "inline", as sufficiently-old GCC versions do not
3734 (also, GCC configured to be in pedantic C89 mode does not).
3735 Problem reported by Sumit Pandya in:
3736 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3738 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3739 consider -g to work if it generates warnings when plain compiles
3740 don't. Problem reported by Braden McDaniel in:
3741 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3743 * doc/autoconf.texi (Slashes): New section, to document a problem
3744 reported by Jim Meyering in:
3745 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3747 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3748 linker output files before linking, to work around IRIX 6 linker bug.
3749 Problem reported by Rainer Orth in:
3750 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3752 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3754 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3755 best tool so far counter rely on the tool path variable name to
3756 avoid checks for one tool being affected by the results of running
3757 the length check on a previous tool.
3759 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3760 match expression argument, as different greps have different
3761 regular expression flavours.
3762 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3763 literals.
3764 (AC_PROG_EGREP): Pass 'EGREP$'.
3765 (AC_PROG_GREP): Pass 'GREP$'.
3767 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3769 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3770 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
3772 2004-03-29 Paul Eggert <eggert@twinsun.com>
3774 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3775 Types, Specific Compiler Characteristics, System Services,
3776 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3777 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3778 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3779 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
3780 Likewise.
3781 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
3782 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
3783 AC_TYPE_OFF_T): Likewise.
3784 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
3785 Likewise.

3788 pacify libtool 1.5.2. Fix quoting problems in sed command.
3790 2004-03-28 Paul Eggert <eggert@twinsun.com>
3792 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3793 now defines HAVE_DECL_TZNAME if it is declared, when
3794 HAVE_STRUCT_TM_TM_ZONE is not defined.
3795 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3796 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3797 for HAVE_TZNAME.
3799 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3801 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
3802 superfluous backslashing of quotes (") in sed expressions;
3803 thanks to Paul Eggert.
3805 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
3807 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
3808 Fortran compiler is ifort, also added pghpf; thanks to Nelson
3809 H. F. Beebe for the bug report.
3811 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3813 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3814 quoted -cmdline argument in Portland Group compiler (bug
3815 reported by Jeffrey J. Barteet).
3817 2004-03-25 Kevin Ryde <user42@zip.com.au>
3819 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
3820 (Run Time): ... here, where it's now mentioned.

3824 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
3825 inherits from language Autoconf-without-aclocal-m4.
3826 (Customizing autom4te): Adjust example; the cache must now be
3827 disabled for language Autoconf-without-aclocal-m4.

3840 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
3841 AC_CHECK_TOOLS.
3842 (Specifying Names): Document the reason for these future
3843 behavioral changes.
3844 * tests/mktests.sh: Do not generate tests for the
3845 new macros.
3846 * NEWS: Document these changes.
3848 * doc/autoconf.texi: Avoid macros with unbraced arguments,
3849 they make TeX hang up.

3854 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3855 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3856 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3857 vowel.
3858 (AC_CHECK_ALIGNOF): New macro.
3859 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
3860 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to

3863 2004-03-03 Paul Eggert <eggert@twinsun.com>
3865 * bin/Makefile.am (edit): Don't use $< in a context where
3866 POSIX doesn't require support for it. Use $@.in instead.
3867 Problem reported by Anthony N. Frasso in
3868 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3869 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3871 2004-02-23 Gary V. Vaughan <gary@gnu.org>
3873 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
3874 from the next generation of Libtool.
3875 * lib/autom4te.in (Autoreconf-preselections): Ditto.
3877 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3879 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
3880 is not always thread-safe. Report from Nathanael Nerode.
3882 2004-02-18 Paul Eggert <eggert@twinsun.com>
3884 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3885 problem on QNX reported by Stephen Rasku in
3886 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3888 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
3889 $(m4sh_m4f_dependencies); this removes a FIXME.
3890 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
3891 (MAINTAINERCLEANFILES): Split into pieces,
3892 one per related section. Add $(srcdir)/wrapper.in.
3894 2004-02-09 Paul Eggert <eggert@twinsun.com>
3896 * doc/autoconf.texi (Setting Output Variables): Emphasize that
3897 AC_SUBST provides no portable way to escape literal newlines.
3899 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3900 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3901 Darwin uses -lcrt2.o and there's little point to cataloging all
3902 the system variants. Partial fix reported by Andreas Waechter in:
3903 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
3904 for bug reported by Nelson H. F. Beebe in:

3907 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
3909 * doc/autoconf.texi (AU_DEFUN): Fix English,
3910 suggested by Paul Eggert.
3911 * lib/autoconf/autoupdate.m4: Correct reference to
3912 acobsolete.m4, suggested by Alexandre Duret-Lutz.
3914 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

3917 refer to the correct file.
3918 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
3919 the behavior of the third argument.
3920 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
3921 correctly the behavior of the third argument. Document
3922 what the three macros that AU_DEFUN defines do. Fix
3923 warning message when the third argument includes $0
3924 (reported by Alexandre Duret-Lutz).
3926 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3927 Eric Sunshine <sunshine@sunshineco.com>
3928 Paul Eggert <eggert@twinsun.com>
3930 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
3931 (AS_INIT): Output shell initialization there. Removed optional
3932 parameter. Expand _AS_SHELL_FN_SPY.
3933 (AS_INIT_WITH_SHELL_FN): Removed.
3934 (_AS_SHELL_FN_SPY): New macro.
3935 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3936 macros.
3937 (AS_SHELL_SANITIZE): Remove loop to find better shell
3938 and documentation for the parameter.
3939 (_AS_DETECT_BETTER_SHELL): Move it here.
3940 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
3941 (_AS_RUN): Move it here, support testing with eval.
3942 (AS_REQUIRE_SHELL_FN): Require shell functions when
3943 it is used.
3944 (_AS_LINENO_WORKS): Put around braces, we do not
3945 trigger the bash bug anymore.
3946 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3947 use AS_INIT_WITH_SHELL_FN.
3948 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3950 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3952 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

3967 * lib/autoconf/status.m4: Remove FIXME.
3968 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
3969 that the macro is not present anymore in the updated
3970 configure.ac.
3971 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
3972 of autoupdate.

3977 copyright years.
3978 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
3979 2003 (except 1997) to the list of copyright years. This undoes
3980 the 2003-05-22 change, which removed the older years from the list.
3981 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
3983 2004-01-27 Gary V. Vaughan <gary@gnu.org>

3987 grep or ggrep program in PATH that accepts as long lines as
3988 possible.
3989 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
3990 AC_PROG_GREP.
3991 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
3992 egrep and fgrep respectively if $GREP -E/-F don't work.
3993 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
3994 _AC_PROG_GREP, and AC_PROG_SED.
3995 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
3996 longest input length accepted by a command.
3997 (AC_PROG_SED): Use it.
3998 * doc/autoconf.texi (Particular Programs): Document the changes.
3999 * NEWS: Updated.
4001 2004-01-27 Paul Eggert <eggert@twinsun.com>
4003 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4008 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4009 bin/autoconf.in, config/Makefile.in, config/config.guess,
4010 config/config.sub, config/install-sh, config/mdate-sh,

4023 sources.
4025 2004-01-26 Paul Eggert <eggert@twinsun.com>
4027 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4028 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4029 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4030 not <inttypes.h>. Problem reported by Tim Mooney in
4031 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4032 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4033 Likewise.
4035 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4036 otherwise "make check" fails because it forbids cmp (I guess
4037 because cmp treats files as binary on DOS-like systems).
4039 * tests/mktests.sh: Update copyright date to 2004, since some tests
4040 have changed in 2004.
4042 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4044 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4045 non-truncating sed or gsed program in PATH.
4046 * tests/acprograms.at: Add it.
4047 * doc/autoconf.texi (Particular Programs): Document it.
4048 * NEWS: Updated.
4050 2004-01-15 Paul Eggert <eggert@twinsun.com>
4052 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4053 -std1 disables some useful extensions on Tru64. Problem reported
4054 by N. Lichtmaier in
4055 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4057 2004-01-14 Paul Eggert <eggert@twinsun.com>
4059 * doc/autoconf.texi (Programming in M4sh): Document that
4060 AS_MKDIR_P succeeds if the destination is a symbolic link
4061 to an existing directory.
4062 (Limitations of Usual Tools): Note that mkdir -p might not
4063 succeed on symlinks to directories.
4065 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4067 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4068 * bin/autoheader.in: Grammar fix in message.
4069 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4070 Test for dir before calling mkdir -p. (trivial changes)
4072 2004-01-13 Eric Blake <ebb9@byu.net>
4074 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4075 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4077 2004-01-10 Jim Meyering <jim@meyering.net>
4079 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4081 2004-01-09 Paul Eggert <eggert@twinsun.com>
4083 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4084 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4085 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4086 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4087 AC_COMPILE_IFELSE, since we now assume our caller invokes
4088 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4089 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4090 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4091 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.

4095 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4096 `"'...'"`, as it's confusing (and I suspect it may not work on
4097 some platforms). The code was incorrect anyway, as it assumed
4098 that \$ evaluated to itself in that context. Reported by
4099 Alexandre Duret-Lutz.

4570 2003-09-26 Akim Demaille <akim@epita.fr>
4572 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4573 directory for AC_CONFIG_COMMANDS' first argument exists.
4574 This makes valid the invocation of _AC_SRCPATH that follows.
4575 Reported by Eric Sunshine.
4576 * doc/autoconf.texi (Configuration Commands): Adjust.
4578 2003-09-26 Akim Demaille <akim@epita.fr>
4580 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4581 Reported by Ralf Corsepius.
4583 2003-09-26 Akim Demaille <akim@epita.fr>
4585 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4586 arguments.
4587 Actually, use AU_ALIAS.
4588 From Bruno Haible.
4590 2003-09-26 Paul Eggert <eggert@twinsun.com>
4592 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
4593 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

4599 The test suite are sometimes assigning timings incorrectly.
4600 Reported by Henk Krus.
4601 Diagnosed by Nicolas Joly.
4603 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4604 AT_help_all.
4605 Instead of making AT_help a sequence of assignments to grow
4606 $at_help_all, just make AT_help_all be the growing contents of
4607 $at_help_all, and make a single assignment in...
4608 (AT_INIT): here.
4609 (at_times_skip): Flip the meaning and rename as...
4610 (at_times_p): this.
4611 (AT_INIT): When summarizing the test that ran, remove
4612 $at_times_file after use, and check it is present before trying to
4613 use it.
4615 2003-09-25 Akim Demaille <akim@epita.fr>
4617 Version 2.57d.
4619 * bin/Makefile.am (edit): Handle '@configure_input@'.
4620 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
4621 (ifnames): chmod -w.
4622 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4623 executables, not bin/ executables! Otherwise all the magic needed
4624 to find non installed files is turned off. This caused a failure
4625 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4626 as found in its environment (sent by tests/autoreconf): pointing
4627 to bin/autom4te that could not find its files.
4628 * tests/mktests.sh: Force the replacement of generated files, for
4629 the sake of "mv" program that are interactive when overwriting a
4630 -w file.
4631 * config/install-sh: Upgrade from CVS Automake.
4633 2003-09-23 Paul Eggert <eggert@twinsun.com>
4635 * doc/autoconf.texi (Limitations of Builtins): Document test -h
4636 versus test -L issues.
4638 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4639 Paul Eggert <eggert@twinsun.com>
4641 Trivial change to support GCC's configuration procedure.
4642 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4643 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4644 about inconsistency if the preprocessor is set to give errors for
4645 any warning.
4646 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4648 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
4650 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
4651 and XFile.pm from Automake.

4662 from masters.
4664 2003-09-12 Akim Demaille <akim@epita.fr>
4666 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
4667 not asm/types.h.
4669 2003-09-11 Akim Demaille <akim@epita.fr>
4671 * doc/autoconf.texi (Header Portability): linux/random.h.
4672 From Peter Hendrickson.
4674 2003-09-10 Akim Demaille <akim@epita.fr>
4676 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4677 willing to edit the output files.
4679 2003-09-10 Akim Demaille <akim@epita.fr>
4681 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4682 and AC_FC_FREEFORM.
4683 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4684 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
4686 2003-09-09 Akim Demaille <akim@epita.fr>
4688 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

4697 2003-09-07 Paul Eggert <eggert@twinsun.com>
4699 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
4700 Improve the accuracy of the wording about obsolescence.
4701 From a suggestion by Ian Lance Taylor in
4702 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
4704 2003-09-05 Paul Eggert <eggert@twinsun.com>
4706 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4707 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4709 2003-09-04 Akim Demaille <akim@epita.fr>
4711 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4712 AC_FUNC_WAIT3.
4714 2003-09-04 Akim Demaille <akim@epita.fr>
4716 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4717 (freeze): When exiting, use $exit_code.
4718 * lib/autoconf/fortran.m4: Comment changes.
4720 2003-09-04 Akim Demaille <akim@epita.fr>

4724 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4726 Add support for newer Fortran dialects. The F77 interface is
4727 unchanged, and continues to support Fortran 77. New FC macros
4728 correspond to all the old F77 macros, with output variables FC,
4729 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4730 available dialect, but older dialects can be specified. There are
4731 new macros AC_FC_SRCEXT to set the source extension, and
4732 AC_FC_FREEFORM to accept free-form source files.
4734 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4735 New macros.
4736 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

4751 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
4752 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
4753 Rewrite in terms of the above.
4754 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
4755 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
4756 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
4757 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

4761 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
4762 Document problems with timestamp resolution that 'make', 'cp -p', and
4763 'touch -r' have.
4765 2003-08-27 Akim Demaille <akim@epita.fr>
4767 * tests/m4sugar.at (cross_warning): Make sure to enable the
4768 output, so that we can track spurious m4sugar output.
4769 * tests/local.at: Require 2.57.
4770 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4771 are defaulted by AT_CHECK anyway.
4772 Use AT_CHECK_AUTOM4TE.
4773 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4774 missing dnl.
4776 2003-08-27 Akim Demaille <akim@epita.fr>
4778 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4779 when -Wobsolete is set.

4843 (&verbose): Remove.
4844 (&getopt): Adjust the note and verb channels, depending upon
4845 --verbose.

4847 * bin/autoupdate.in: Adjust.
4848 Use &verb, not &verbose.
4850 2003-08-21 Akim Demaille <akim@epita.fr>
4852 * bin/autoheader.in (&parse_args): Use &parse_warnings and
4853 &parse_WARNINGS.
4854 ($help): Use Autom4te::ChannelDefs::usage.
4855 * bin/autoscan.in: Use Autom4te::ChannelDefs.

4858 2003-08-21 Akim Demaille <akim@epita.fr>
4860 First stab at preserving warnings between calls to autom4te,
4861 including when the cache is used.
4863 There are still several issues: (i) there are too many runs of m4
4864 (one for include, one for warnings, and some more), (ii) warnings
4865 spreading on several lines are not handled gracefully, (iii) the
4866 code meant to have the call stack display for errors does not work
4867 (its handling should move from m4 to autom4te).
4869 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4870 Use them.
4871 (@preselect): Add m4_warn.
4872 ($exit_status): Remove, use $exit_code.
4873 ($help): Use Autom4te::ChannelDefs::usage.
4874 (&handle_m4): No longer define the m4_warnings.
4875 At each run, extract and report the warnings.
4876 Always cache the result, including if the exit status is on
4877 failure, since if nothing changes, we should result in the same
4878 failure, hence we can use the cache.
4879 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4880 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4881 Remove.
4882 (m4_warn): Redefine as a do-nothing: it is its invocation that
4883 matters, as warnings are now reported via traces.
4884 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4885 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4886 the latter reveals calls to the former.
4888 Adjust the tests.
4890 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4892 2003-08-21 Akim Demaille <akim@epita.fr>
4894 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

4899 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4900 forward order.
4901 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4902 (&parse_warnings): Accept a list of warning requests.

4904 (cross): New warning category.
4906 2003-08-21 Akim Demaille <akim@epita.fr>
4908 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4909 (&require_configure_ac): Accept an optional directory argument.
4910 ($configure_ac): Remove.
4911 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4912 (&catfile): Remove.
4913 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4914 * bin/autoscan.in: Adjust.
4916 2003-08-20 Akim Demaille <akim@epita.fr>
4918 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4919 Reported by Alexandre Duret-Lutz.
4921 2003-08-20 Akim Demaille <akim@epita.fr>
4923 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4924 * bin/autom4te: Adjust.
4925 In particular, be Autoconf tools are really silent when properly
4926 working, bind the verbosity of the 'note' channel to $verbose.
4927 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4928 (&xsystem, &contents): Remove, since they are exported by...
4929 * lib/Autom4te/FileUtils.pm: this.
4930 More perldoc.
4931 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4932 * lib/Autom4te/FileUtils.pm: here.
4934 2003-08-20 Akim Demaille <akim@epita.fr>

4989 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4990 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4991 shorter column three. Add DESCRIPTION to log file content.
4993 2003-08-13 Derek Price <derek@ximbiot.com>
4995 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5032 (This really should be 'intptr_t', not 'long', but that would

5047 From Gareth McCaughan.
5049 2003-06-23 Akim Demaille <akim@epita.fr>
5051 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5052 not all of them. This fixes 1. the fact that when testing
5053 Autoconf there are many many config.log, 2. the incorrect use of
5054 top_srcdir to find config.log.
5055 Don't mix the detailed output of failed test with the summary of
5056 failures. Rather, append detailed log afterwards.
5058 2003-06-23 Akim Demaille <akim@epita.fr>
5060 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5061 always run: output config.log on $at_group_log.
5063 2003-06-23 Akim Demaille <akim@epita.fr>
5065 * tests/torture.at (#define header templates): Don't use quotes in
5066 C++ comments as it puzzles Emacs' sh font-lock-mode.
5068 2003-06-23 Akim Demaille <akim@epita.fr>
5070 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

5083 ensuring we add -std1 for full-ANSI.
5085 * doc/autoconf.texi (hdrindex): New macro.

5143 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5145 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5146 Do not call `_exit()', simply modify `$?'.
5147 (xsystem): Reset $! before running system, and check it afterward.
5148 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5149 63 for version mismatches.
5151 2003-05-23 Akim Demaille <akim@epita.fr>
5153 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5154 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5155 the middle of a line).
5156 * lib/m4sugar/m4sugar.m4: Likewise.
5157 Remove useless spaces in comments.

5161 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

5173 Paul Eggert <eggert@twinsun.com>
5175 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5176 Remove `#include <stdlib.h>' from the list; we should never
5177 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5178 resulting namespace pollution would cause other tests to fail.
5179 Configure scripts run with some older versions of g++ and HP's
5180 aCC would fail due to such an #include. Problems reported by
5181 Matthew Mueller in <http://bugs.debian.org/120704> and by
5182 Keith Bostic in
5183 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5184 In the test, use the test declaration before including <stdlib.h>,
5185 as that's closer to how it'll be used.
5187 2003-05-23 Akim Demaille <akim@epita.fr>
5189 * doc/autoconf.texi (Header Portability): ucred.h.
5190 From Ian Redfern.
5192 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5194 Overhaul Autotest's logging: generate separate log files
5195 in testsuite.dir/NNN/testsuite.log, and append them to
5196 testsuite.log instead of re-running the test verbosely.
5198 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5199 file descriptor, write 0 to at_status_file instead of setting
5200 at_status=0, initialize some new variables (at_status_file,
5201 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5202 to rerun the tests, instead append the at_group_log to the
5203 at_suite_log when a test fails.
5204 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5205 with the AS_MESSAGE_LOG_FD redirected to stdout.
5206 (AT_CLEANUP): save the output status in $at_status_file
5207 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5208 its original place.
5209 (AT_CHECK): since tests are run with a redirected stdout,
5210 and used to be re-run in verbose mode, turn some $at_verbose
5211 into echo, and don't redirect the output of testing stdout
5212 and stderr.
5214 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5215 the name of the debugging directory and information about
5216 its contents.
5218 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5220 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

5333 and truncate.
5335 2003-05-06 Akim Demaille <akim@epita.fr>
5337 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5338 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5339 by aclocal.m4 is changed it might require the importing of another
5340 m4 extension file, i.e., aclocal must be run.
5342 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5343 (&parse_args): Use --force with aclocal if required and supported.

5351 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5352 argument instead of a file name, so that the request file remains
5353 open during the whole autom4te run.
5354 ($icache_file): New.
5355 (&freeze): Lock the $icache_file.
5357 2003-04-29 Derek Price <derek@ximbiot.com>
5359 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5360 seperator with m4_append_uniq(). It doesn't work.
5361 (AT_CLEANUP): Add `;' to end of at_help_all.
5362 (AT_INIT): Allow --keywords to be specified more than once. When
5363 grepping $at_help_all for keywords, use the field and keyword
5364 seperators to ensure a complete keyword match. Alter at_prev handling
5365 to support the new --keywords behavior.
5367 2003-04-27 Karl Berry <karl@freefriends.org>
5369 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5370 align better with others. I also made some of the individual
5371 entries on one line, for brevity and to make it easier for me to
5372 sort my dir-example file in the Texinfo distribution :).
5374 2003-04-12 Jim Meyering <jim@meyering.net>

5429 2003-03-29 Akim Demaille <akim@epita.fr>

5439 header causes problems.
5441 2003-03-28 Akim Demaille <akim@epita.fr>
5443 * tests/torture.at (Configuring subdirectories): Require aclocal
5444 1.4, otherwise the test fails, as it does support configure.ac.
5445 This fixes the "test 40 failed" bug reports.
5447 2003-03-28 Akim Demaille <akim@epita.fr>
5449 * doc/autoconf.texi (C Compiler): `#line' portability.

5514 * doc/autoconf.texi (Limitations of Make): Remove the section
5515 about `$<' in inference rules, it was a bogus interpretation of
5516 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5517 Tru64 make in the "target lookup" section.
5518 (Automake): Automake 1.5+ no longer requires special tools to be
5519 present on the developer's host.
5521 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
5523 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

5535 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
5536 to cope with DOS-style absolute paths, when constructing
5537 ${ac_make}.
5539 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5540 When constructing paths with IFS=:, quote the path. If we're
5541 constructing a DOS-style absolute path, we don't want to split it
5542 on the colon.
5544 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
5545 in description.
5547 2003-02-25 Pavel Roskin <proski@gnu.org>

5559 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5560 to fix a mismatch between example and discussion.
5562 2003-02-24 Kevin Ryde <user42@zip.com.au>
5564 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5565 format starting with "-".
5567 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5569 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5570 is not portable inside Makefile.
5572 2003-02-20 Akim Demaille <akim@epita.fr>
5574 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5575 compiler says yeah, but preproc says nope, compiler is right.
5576 Conversely, prompt the reader to send a bug report to the
5577 maintainers of the package, not of Autoconf.

5587 $ac_prefix_program.
5588 From Larry Jones.
5590 2002-12-23 Paul Eggert <eggert@twinsun.com>
5592 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5593 innocuous variant befor including <limits.h> or <assert.h>. This
5594 works around a bug reported by Albert Chin: HP-UX 11i
5595 (and earlier versions) have a <limits.h> that declares
5596 gettimeofday and many other functions.
5598 2002-12-03 Paul Eggert <eggert@twinsun.com>
5600 Version 2.57.
5602 * NEWS, configure.ac: Update version.
5604 * doc/fdl.texi: Upgrade to FDL version 1.2.
5606 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5607 nontrivially in main's body, so that f's external declaration is
5608 not optimized away in AIX. This should fix the bug reported by
5609 Martin Frydl in
5610 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5612 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5613 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5614 defined, to support freestanding compilers. This should fix the
5615 bug reported by Momchil Velkov in
5616 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5618 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5619 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

5630 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5631 \(.*\) match is too long and there is something more to be checked.
5632 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
5634 2002-11-15 Akim Demaille <akim@epita.fr>

5641 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
5642 * configure.ac (AM_INIT_AUTOMAKE): here.
5643 Require 1.7.1.
5645 2002-11-14 Akim Demaille <akim@epita.fr>
5647 Version 2.55.
5649 * config/config.guess, config/config.sub, config/install-sh:
5650 Update from masters.
5652 2002-11-14 Akim Demaille <akim@epita.fr>
5654 * Makefile.maint: Sync with Bison, i.e.:
5655 (po-check): Scan .l and .y files instead of the
5656 .c and the .h files that they generate. This fixes the bug
5657 reported by Tim Van Holder in:
5658 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5659 Look for N_ as well as for _. Try to avoid matching #define for
5660 N_ and _.
5661 From Paul Eggert.
5663 2002-11-14 Akim Demaille <akim@epita.fr>
5665 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5666 From Paul Eggert and Albert Chin-A-Young.
5668 2002-11-14 Akim Demaille <akim@epita.fr>
5670 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5671 From Paul Eggert and Albert Chin-A-Young.
5673 2002-11-14 Kevin Ryde <user42@zip.com.au>
5675 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5676 than assigning in main, to avoid HP cc +O3 optimizing it away.
5678 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5680 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5681 option. Process --recheck after parsing all options. Pass -q
5682 option to configure on --recheck.
5683 (AC_OUTPUT): Pass -q from configure to config.status.
5684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5685 arguments to record.
5686 * doc/autoconf.texi (config.status Invocation): Document
5687 config.status -q option.
5689 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
5691 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
5692 Makefile.in if Makefile.am exists.

5694 output AC_CONFIG_FILES if no Makefiles were found.
5696 2002-11-07 Akim Demaille <akim@epita.fr>

5711 * tests/torture.at (Configuring subdirectories): Don't use grep
5712 -w.
5713 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
5714 Reported by Ezra Peisach.
5716 2002-11-05 Akim Demaille <akim@epita.fr>
5718 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5719 Remove.
5720 We _have_ to stop using the old compatibility scheme that tried to
5721 avoid useless backslashes because Libtool 1.4.3 contains a
5722 AC_DEFINE([error_t], [int],
5723 [Define to a type to use for \`error_t' if it is not
5724 otherwise available.])
5725 We _have_ to quote the single quote and backslashes with \. The
5726 old compatibility scheme saw that ` was backslashed, and therefore
5727 did not quote the single quote. Hence before this patch, Autoconf
5728 was not compatible with Libtool.
5730 2002-11-04 Paul Eggert <eggert@twinsun.com>
5732 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

5748 from...
5749 (&autoreconf): here.
5750 ($help, $make, &parse_args, &autoreconf_current_directory):
5751 Support -m/--make.
5752 * doc/autoconf.texi (autoreconf Invocation): Adjust.

5770 2002-10-31 Akim Demaille <akim@epita.fr>
5772 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5773 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5774 Make variable, not a shell variable.
5775 Suggested by Bruno Haible.
5777 2002-10-31 Akim Demaille <akim@epita.fr>
5779 * bin/autom4te.in (load_configuration): Reject #args out of any
5780 language.
5782 2002-10-31 Akim Demaille <akim@epita.fr>

5796 Suggested by Tim van Holder.
5798 2002-10-29 Paul Eggert <eggert@twinsun.com>
5800 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
5801 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5802 Problem reported by Bruno Haible.
5804 2002-10-29 Akim Demaille <akim@epita.fr>
5806 * doc/autoconf.texi (Header Templates): Put also in words what the
5807 pictures says to assist free style readers.
5808 (Customizing autom4te): s/--cache=/--cache /.
5810 2002-10-29 Akim Demaille <akim@epita.fr>
5812 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
5813 sys/wait.h.

6057 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
6058 words about HP-UX cmp: it was actually a user-written cmp.
6060 2002-10-22 Akim Demaille <akim@epita.fr>
6062 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6063 are a few warnings.
6064 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6065 Quote for Perl '' strings, not "".
6066 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6067 strings.
6069 2002-10-22 Akim Demaille <akim@epita.fr>
6071 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6072 characters is a syntax warning now.

6074 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

6079 `@', to tickle Perl's lists.
6080 Reported by Carlos Velasco.
6082 2002-10-18 Akim Demaille <akim@epita.fr>
6084 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
6085 missing included files _are_ errors.
6086 Thanks to Alexandre Duret-Lutz.
6087 * tests/tools.at (autom4te cache): Adjust.
6088 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

6094 2002-10-17 Akim Demaille <akim@epita.fr>
6096 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
6097 Fixes the `AC_ARG_VAR' test failures.

6117 Because of caching, some files that no longer exist and are no
6118 longer required can still cause errors.
6119 Reported by Alexandre Duret-Lutz.
6121 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6122 to frozen files in @ARGV, as @ARGV must remain being a list of
6123 files. Rather, at M4 call sites, use this...
6124 (&files_to_options): New function.
6125 (&freeze): Use &error.
6126 (&up_to_date): If a file that was included according to the cache
6127 is no longer there, then the output is out dated.
6128 (&main): Don't even check whether a file is up to date is anyway
6129 --force is given.
6130 * tests/tools.at (autom4te cache): New.
6132 2002-10-16 Akim Demaille <akim@epita.fr>
6134 * bin/autoconf.as: Kill dead options.
6135 * bin/autoupdate.in (&parse_args): Kill old options.
6136 * bin/autoreconf.in (&parse_args): Remove dead options.
6137 Factor some code.
6138 (&autoreconf): Report the directories we enter *and leave*, so
6139 that error messages can be easily located, and use GNU Make
6140 format, so that Emacs' compile mode understands us.
6141 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6142 if some file was changed instead of `print'.
6143 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6144 (&parse_args): Remove the dead options.
6145 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
6146 autoheader's quiet mode.

6151 2002-10-11 Akim Demaille <akim@epita.fr>

6154 check for compilability.
6156 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6157 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

6159 (AC_CHECK_HEADER): this.
6161 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6162 numbers in the Subject suggestion.

6176 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6177 file name to enable parallel executions.
6178 From Sam Varshavchik.
6180 2002-10-08 Akim Demaille <akim@epita.fr>
6182 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6183 aclocal invocation, as Gettext macros might not be visible to
6184 aclocal.
6185 Instead of blindly running autopoint, scan configure.ac (not the
6186 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6187 Reported by Paul D. Smith.
6189 2002-10-08 Paul Eggert <eggert@twinsun.com>
6191 Work around problems found when POSIXLY_CORRECT=1 is set.
6192 None of this seems to have anything to do with POSIX, really,
6193 but it's how Perl getopt works.
6194 * bin/autom4te.in (parse_args): Configure GetOpt with
6195 "permute", too.
6196 * doc/autoconf.texi (Invoking autom4te):
6197 --warning -> --warnings.
6198 * lib/autom4te.in: --warning -> --warnings.
6200 2002-09-28 Akim Demaille <akim@epita.fr>

6217 2002-09-28 Akim Demaille <akim@epita.fr>
6219 * tests/torture.at (Configuring subdirectories): Be robust to
6220 users who use config.site to require for a cache: in this case,
6221 the two last configure runs, using two different sets of
6222 arguments, trigger a legitimate error.
6224 2002-09-28 Akim Demaille <akim@epita.fr>
6226 * tests/m4sh.at (Functions Support, Functions and return Support):
6227 New.

6240 (tm_zone): Move their rules to...
6241 * lib/autoconf/types.m4: here, using AN_ macros.
6242 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6243 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6244 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6245 * lib/autoconf/programs.m4: here.
6246 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

6257 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6258 (.m4.m4f): Don't pass --prepend-include, since that's done by
6259 tests/autom4te itself.
6260 * lib/autoscan/Makefile.am: Include freeze.mk.
6261 (autoscan.list): New target --this file is no longer a source.
6262 (autoscan.pre): New file.
6264 2002-09-28 Akim Demaille <akim@epita.fr>
6266 * bin/autoscan.in (@kinds): Make them singular.
6267 Adjust all uses.
6268 (&init_tables): When --debug, report the list of rules to ease
6269 tracking changes in autoscan.list.
6270 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6272 2002-09-28 Akim Demaille <akim@epita.fr>

6283 * lib/autoscan/identifiers, lib/autoscan/makevars,
6284 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6285 `functions' line is now prefixed with `function:'.
6286 * bin/autoscan.in (&init_tables): Adjust.
6288 2002-09-28 Akim Demaille <akim@epita.fr>
6290 From now on, autoscan files must always map a macro name to a
6291 word: there is no `default' macro for autoscan.
6293 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6294 all.
6295 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6296 explicit.
6298 2002-09-28 Akim Demaille <akim@epita.fr>
6300 * bin/autoscan.in (%c_keywords): Remove.
6301 (&used): Keep only track of the words we might be interested in.

6332 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6333 Reported by Ralf Corsepius.
6334 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6336 2002-09-26 Akim Demaille <akim@epita.fr>
6338 Single suffix rules and seperated dependencies are not portable.
6340 * doc/autoconf.texi (Installation Directory Variables): Update.
6341 (Limitations of Make): Some about `Single Suffix Rules and

6346 2002-09-25 Paul Eggert <eggert@twinsun.com>

6351 2002-09-24 Paul Eggert <eggert@twinsun.com>

6356 * bin/Makefile.am (SUFFIXES, .in): Remove.
6357 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

6360 2002-09-16 Akim Demaille <akim@epita.fr>
6362 i960 compilers create `b.out' files by default.
6363 Reported by Ralf Corsepius.
6365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

6384 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6385 reading config.log when the compiler is rejected.
6386 Suggested by Guido Draheim.
6388 2002-09-13 Akim Demaille <akim@epita.fr>
6390 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6391 (chdir_init) might hang when stat'ing mounted directories.
6392 Reported by Vance Shipley.
6394 2002-09-12 Akim Demaille <akim@epita.fr>
6396 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6397 the lists.
6399 2002-09-12 Akim Demaille <akim@epita.fr>
6401 * doc/autoconf.texi (Defining Symbols): Present two different
6402 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

6407 * doc/autoconf.texi: Review grammar and punctuation.

6412 grammatical typos.
6413 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6414 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6415 is obsolescent.
6417 2002-09-11 Akim Demaille <akim@epita.fr>
6419 * doc/autoconf.texi (Questions): Rename as...
6420 (FAQ): this.

6435 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6436 `duplicates', since the algorithm was too naive and could keep
6437 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6438 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6439 Reported by Ralf Corsepius.
6440 * tests/torture.at (Configuring subdirectories): Exercise these
6441 cases.
6443 2002-09-09 Akim Demaille <akim@epita.fr>

6446 looking for a replacement file.
6447 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6448 directory is relative.
6449 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6450 directory definition.
6451 Reported by Andreas Schwab and Jim Meyering.
6453 2002-09-06 Akim Demaille <akim@epita.fr>

6456 precious variables are.
6457 Suggested by Pontus Skoeld.
6459 2002-09-05 Akim Demaille <akim@epita.fr>
6461 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6462 (ifnames, autoscan, autom4te): Since we don't only depend on
6463 configure.ac variables (such as VERSION etc.), but also on prefix
6464 and so forth, depend on Makefile, not configure.ac.
6465 Reported by Alexandre Duret-Lutz.
6466 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6468 2002-09-05 Kevin Ryde <user42@zip.com.au>
6470 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6471 doesn't seem to be confined to ia64, just say "some versions".
6473 2002-09-04 Akim Demaille <akim@epita.fr>
6475 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by

6488 * configure.ac: Bump to 2.53d.
6489 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6490 as of today, on Automake's team suggestion.
6492 2002-09-03 Akim Demaille <akim@epita.fr>
6494 Version 2.53c.
6496 2002-09-02 Akim Demaille <akim@epita.fr>
6498 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6499 SITE_MACRO_DIR.
6500 * configure.ac: Disable SITE_MACRO_DIR.
6502 2002-09-02 Jim Meyering <meyering@lucent.com>
6504 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6505 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6506 Also, tweak grammar: s/make sure to/be sure to/.
6508 2002-09-02 Paul Eggert <eggert@twinsun.com>
6510 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6511 directory names are generally preferable to physical names.
6513 2002-09-02 Akim Demaille <akim@epita.fr>
6515 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6516 Reported by Raja R. Harinath.
6517 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6518 * bin/autoupdate.in: Use error instead of die.
6520 2002-09-01 Paul Eggert <eggert@twinsun.com>
6522 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6523 ordinary shell concatenation rather than echo+tr+sed command that
6524 runs afoul of a long-line-related sed bug in Solaris 8.
6526 * bin/autoheader.in (parse_args): --warning -> --warnings.
6528 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6529 stdout, as traditional "ls" does.
6530 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6531 _AC_COMPILER_EXEEXT_O): Likewise.
6532 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6534 * bin/autoconf.as: Add --prepend-include option. This patch was
6535 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6536 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6538 * bin/autoconf.in, configure: Regenerate.
6540 * doc/autoconf.texi (Special Shell Variables): Mention
6541 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6543 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6544 MAILPATH and set PS1, PS2, PS4 to default values, to work
6545 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6546 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6547 the Autoconf documentation specifies; fall back to "unset" only if
6548 this fails. Use a shell for-loop for this rather than an m4 loop,
6549 to shorten the output script.
6551 2002-08-30 Paul Eggert <eggert@twinsun.com>
6553 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6554 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6555 for the CDPATH problem. Document PWD.
6556 (Limitations of Builtins): Document the problem that "cd $foo" and
6557 "ls $foo" may refer to different directories in shells conforming
6558 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6559 example, since the old example is now out of date.
6561 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6562 FOO" and "ls FOO" talk about different directories; this catches
6563 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6564 spaghetti.
6566 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6567 of rolling our own unset.
6568 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6569 in practice we needn't worry about CDPATH if unset doesn't work.
6571 * Makefile.in, aclocal.m4, bin/Makefile.in,
6572 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6573 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6574 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6575 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6576 tests/Makefile.in: Regenerate with Automake 1.6.3.
6578 * config/config.guess, config/config.sub, config/mkinstalldirs:
6579 Update.
6581 * configure: Regenerate with self.
6583 2002-08-30 Kevin Ryde <user42@zip.com.au>
6585 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6586 default output.
6588 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6590 * bin/autom4te.in (Request::load): Correctly test for "do" read
6591 failure.
6593 2002-08-29 Akim Demaille <akim@epita.fr>
6595 * lib/Autom4te/General.pm (&xqx): New.
6596 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6597 hand, which is not portable.
6598 (&error): New.
6599 * bin/autom4te.in: Use them.
6600 Use &error instead of die.
6601 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6602 Adjust.
6604 2002-08-17 Paul Eggert <eggert@twinsun.com>
6606 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6607 default list of compilers to try, since it was long ago superseded
6608 by the ksh fc builtin. Suggested by Steven G. Johnson.
6610 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6612 * doc/autoconf.texi (Invoking autom4te): End the option table,
6613 fixing a bug introduced by the previous patch.
6614 (Limitations of Make): Add a 'target lookup' subentry in the
6615 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6617 2002-07-29 Mark D. Roth <roth@feep.net>
6619 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6620 options and use $AUTOM4TE_PATH.
6621 * doc/autoconf.texi: Remove documentation of autom4te
6622 --include-envvar and --site-macro-subdir options and document
6623 use of $AUTOM4TE_PATH.
6624 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6625 arguments from each language section.
6627 2002-07-29 Paul Eggert <eggert@twinsun.com>
6629 * doc/install.texi: Include copyright symbol in copyright notice.
6631 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6632 Replace with:
6633 (AM_MAKEINFOFLAGS): New macro.
6634 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6635 * Makefile.am (INSTALL): Use the new macros.
6636 Use -o rather than --output, since "missing" does not grok --output.
6638 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6640 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6641 comments do not always work. Never trust the exit status of
6642 `make -k'.
6644 2002-07-24 Kevin Ryde <user42@zip.com.au>
6646 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6647 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6649 2002-07-23 Paul Eggert <eggert@twinsun.com>
6651 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6652 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6653 apparently treats PATH="nonexistent" as if it contained ".".
6654 Bug reported by Stefan `Sec' Zehl.
6656 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6658 * doc/autoconf.texi (Limitations of Make): Mention the special
6659 handling of the obj/ directory by BSD make.
6661 2002-07-20 Kevin Ryde <user42@zip.com.au>

6675 2002-07-18 Akim Demaille <akim@epita.fr>
6677 Version 2.53b.
6679 2002-07-18 Akim Demaille <akim@epita.fr>
6681 * config/config.guess, config/config.sub: Update.
6683 2002-07-18 Akim Demaille <akim@epita.fr>
6685 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
6686 Automake's parts.
6688 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
6689 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
6690 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
6692 2002-07-18 Akim Demaille <akim@epita.fr>,
6693 Alexandre Duret-Lutz <duret_g@epita.fr>
6695 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
6696 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

6705 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
6706 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
6707 latter was not run.
6709 2002-07-17 Akim Demaille <akim@epita.fr>
6711 * lib/Autom4te/General.pm (find_file): Browse the directories in
6712 the order they are given.

6732 macro directory, remove note that include path directories are
6733 used in reverse order, and document --prepend-include option.
6734 * lib/autom4te.in: Use --prepend-include instead of --include.
6735 * tests/wrapsh.in: Use --prepend-include instead of --include.

6773 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
6775 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6776 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
6777 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
6778 so that Emacs setups GNU style for perl-mode and cperl-mode.
6780 2002-06-27 Paul Eggert <eggert@twinsun.com>
6782 * config/install-sh: Quote $src. Prefer || to test's -o option,
6783 as per "Limitations of Builtins".
6784 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
6785 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6787 * tests/mktests.sh: Use grep instead of fgrep, as per
6788 "Limitations of Builtins".
6790 2002-06-15 Paul Eggert <eggert@twinsun.com>
6792 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
6793 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
6794 so that we consistently test the just-built programs.
6795 * tests/wrappl.as: Likewise.
6797 2002-06-12 Paul Eggert <eggert@twinsun.com>
6799 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
6800 name, so that symlinks to 'autoconf' work properly. Bug reported
6801 by Bruno Haible.
6802 * bin/autoheader.in (AUTOM4TE): Likewise.
6803 * bin/autoreconf.in (autoconf, autoheader): Likewise.
6804 * bin/autoscan.in (autom4te): Likewise.
6805 * bin/autoupdate.in (autom4te): Likewise.
6807 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
6808 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
6809 on Solaris 2.5.1.
6811 2002-06-11 Andreas Schwab <schwab@suse.de>
6813 * doc/autoconf.texi: Add more dir entries.
6815 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
6817 * bin/autom4te.in ($cache): Don't define using `$me', the name
6818 of the cache should not depend on the name under which autom4te
6819 was installed.
6821 2002-06-07 Akim Demaille <akim@epita.fr>
6823 * tests/tools.at (autoconf: forbidden tokens, basic)
6824 (autoconf: forbidden tokens, exceptions): Adjust to the change of
6825 words in autom4te.in.
6827 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
6829 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
6830 _AC_LANG_PROGRAM_C_F77_HOOKS.
6832 2002-06-07 Akim Demaille <akim@epita.fr>
6834 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
6835 rename as...
6836 (AC_REPLACE_FNMATCH): this.
6837 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
6838 AC_FUNC_FNMATCH_GNU.
6840 2002-06-07 Akim Demaille <akim@epita.fr>
6842 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
6843 Rosetta Stone for Unix.
6845 2002-06-07 Akim Demaille <akim@epita.fr>
6847 * bin/autom4te.in (warn_forbidden): When rejecting a token,
6848 suggest m4_pattern_allow.
6849 Suggested by Adam J. Richter.
6851 2002-06-07 Akim Demaille <akim@epita.fr>
6853 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
6854 ac_config_libobj_dir.
6855 (AC_CONFIG_LIBOBJ_DIR): New.
6856 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
6857 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
6858 Use ac_config_libobj_dir to find the replacement files.
6859 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
6860 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
6861 (AC_REPLACE_FNMATCH_GNU): these.
6862 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
6863 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
6864 * tests/mktests.sh (ac_exclude_list): Don't check
6865 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
6867 2002-06-06 Paul Eggert <eggert@twinsun.com>
6869 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
6870 if ln doesn't work.
6871 * NEWS: Likewise.
6872 * doc/autoconf.texi (Configuration Links): Likewise.
6873 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
6875 2002-06-05 Paul Eggert <eggert@twinsun.com>
6877 * config/config.guess, config/config.sub, config/texinfo.tex:
6878 Update from masters.
6880 2002-05-29 Paul Eggert <eggert@twinsun.com>
6882 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
6883 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
6884 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

6891 * lib/m4sugar/Makefile.am (check-local): Likewise.
6892 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
6893 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
6895 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
6896 * doc/autoconf.texi (Particular Programs): Document them.
6897 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
6898 * NEWS: Likewise.
6900 2002-05-27 Paul Eggert <eggert@twinsun.com>
6902 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
6903 * NEWS, doc/autoconf.texi (Particular Types): Document it.
6904 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
6905 instead of AC_MBSTATE_T, which never existed.
6907 2002-05-23 Akim Demaille <akim@epita.fr>
6909 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
6910 version of Autoconf that is discussed.
6912 2002-05-22 Paul Eggert <eggert@twinsun.com>
6914 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
6915 from the default list of compilers to try. Suggested by
6916 Kate Hedstrom.
6917 * NEWS: Document the above.
6918 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
6920 2002-05-17 Paul Eggert <eggert@twinsun.com>
6922 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
6923 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6924 This improves on an earlier suggestion by H. Peter Anvin.
6926 2002-05-16 Paul Eggert <eggert@twinsun.com>
6928 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6929 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6930 Both macros now accept an optional source-dir arg.
6931 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6933 * NEWS: Document this.
6934 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6936 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6937 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6938 not for GNU extensions; this undoes part of the 2000-11-03 change,
6939 reverting to 2.13-compatible behavior.
6940 Add new optional argument DIR.
6941 (AC_FUNC_FNMATCH_GNU): New macro.
6943 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6945 2002-05-08 Paul Eggert <eggert@twinsun.com>
6947 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6948 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6949 and it causes a 'test' syntax error if it fails.
6950 Bug reported by Stephen Gildea.
6952 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6953 If prototypes are supported, use them to check this at compile-time,
6954 instead of trying to check it at run-time. If we must do a run-time
6955 check, assume that setvbuf is standard when cross-compiling, as
6956 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6957 Bug reported by Paul D. Smith.
6959 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6960 argument specifying location of getloadavg.c. This removes a
6961 FIXME. This idea was taken from Jim Meyering's implementation in
6962 textutils.
6963 * doc/autoconf.texi (Particular Functions): Document this.
6964 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6965 that's what the code does; this fixes a bug reported by
6966 Paul D. Smith.
6968 2002-05-03 Akim Demaille <akim@epita.fr>
6970 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6971 autopoint instead of gettextize.
6972 ($uses_alocal): Rename as...
6973 ($uses_aclocal): this.
6974 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6975 Suggested by Bruno Haible.
6977 2002-05-03 Akim Demaille <akim@epita.fr>
6979 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
6981 2002-04-29 Paul Eggert <eggert@twinsun.com>
6983 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
6984 files to be 1 second older; just set them to be the same time.
6985 Also, sleep 1 second after the first aclocal, to work around
6986 problems with sub-second time stamps on the input files.
6988 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6990 * doc/autoconf.texi: Mention "set -e -x" lossage
6991 under node "Limitations of Builtins".
6993 2002-04-29 Akim Demaille <akim@epita.fr>
6995 * doc/install.texi: Better wording for setting variables when
6996 running configure.
6997 From Christian Cornelssen.
6999 2002-04-29 Akim Demaille <akim@epita.fr>
7001 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7002 of lack of $LINENO support, then the test will compare the $LINENO
7003 in testsuite vs. the lineno in the test file. This is wrong, of
7004 course.
7005 Be sure to protect it.
7006 Reported by Patrick Welche.
7008 2002-04-25 Akim Demaille <akim@epita.fr>
7010 * doc/autoconf.texi (Obsolete Macros): Typo.
7011 Reported by Vladimir Volovich.
7013 2002-04-25 Akim Demaille <akim@epita.fr>
7015 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7016 than some of the input files, hence, on the second run of aclocal,
7017 if some of its input are younger, make them older.
7018 Suggested by Paul Eggert.
7020 2002-04-25 Akim Demaille <akim@epita.fr>
7022 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7023 Thanks to Paul Eggert.
7025 2002-04-25 Akim Demaille <akim@epita.fr>
7027 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7028 and ac_subst_vars be sh variables containing the list of
7029 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7030 DEFAULT diversion.
7031 (_AC_INIT_PREPARE): Use them to log them.
7032 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7033 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7034 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7035 _AC_SUBST_FILES and _AC_SUBST_VARS.
7036 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7038 2002-04-24 Akim Demaille <akim@epita.fr>
7040 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7041 autoheader, so that automake does not complain about a missing
7042 config.h.in that was to be created.
7044 2002-04-23 Akim Demaille <akim@epita.fr>
7046 * bin/autoheader.in (parse_args): --warning takes an argument.
7047 Fixes PR/220.

7051 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7052 and bb.out when cleaning up.

7060 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7062 2002-04-22 Akim Demaille <akim@epita.fr>
7064 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7065 comma.
7066 Reported by Gregory Giannoni.
7068 2002-04-22 Akim Demaille <akim@epita.fr>
7070 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

7077 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7095 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
7096 Minor spelling and grammar fixes.
7098 * doc/autoconf.texi: Follow the outline suggested in the GNU
7099 Sample Texts sections of the Texinfo 4.2 manual. Most
7100 importantly, this makes sure that the copyright notices appear in
7101 all output formats. You probably need Texinfo 4.2 to generate
7102 the manual now.
7104 Fix some bugs when using "$@" when there might be zero positional
7105 arguments in cases where this matters.

7126 that is not portable to Zsh.
7128 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7130 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7131 from aclocal.m4 too.
7133 2002-04-12 Akim Demaille <akim@epita.fr>
7135 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7137 2002-04-10 Akim Demaille <akim@epita.fr>
7139 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7140 workaround for ${1+"$@"}.
7141 * doc/autoconf.texi (Shell Substitutions): Explain it.
7142 From Oliver Kiddle and Peter Stephenson.
7144 Have M4sh perform minimal shell sanitizing.
7146 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7147 part into...
7148 (_AS_PREPARE): this new macro.
7149 (AS_PREPARE): New.
7150 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7151 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7153 Adjust Autoconf and Autotest.
7155 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7156 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7157 * lib/autotest/general.m4 (AT_INIT): Likewise.
7158 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7159 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7160 AS_SHELL_SANITIZE.
7162 Use this M4sh to generate Autoconf's shell scripts.
7164 * tests/wrapsh.as: New, precursor of wrapsh.in.
7165 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7166 on Autotest and M4sh.
7167 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7168 (wrapsh.in): New target.
7169 * bin/autoconf.as: New, precursor of autoconf.in.
7170 (autoconf.in): New target.
7172 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7175 with indented comments in rules.
7177 2002-04-09 Andreas Schwab <schwab@suse.de>
7179 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7180 ac_top_builddir when setting ac_abs_top_builddir.
7182 2002-04-06 Kevin Ryde <user42@zip.com.au>
7184 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7185 (Portable Shell): Cross reference to Systemology.
7187 2002-04-05 Akim Demaille <akim@epita.fr>
7189 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7190 directories when descending in a SUBDIRS.
7191 Reported by Ezra Peisach.
7193 2002-04-04 Andreas Schwab <schwab@suse.de>
7195 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7196 contains no literal separators.
7198 2002-04-03 Akim Demaille <akim@epita.fr>
7200 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7201 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7202 Use dnl, not the KILL diversion.
7203 Extracted from...
7204 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7205 (AC_CONFIG_LINKS): here.
7206 Adjust.
7207 Don't use the KILL diversion, as it kills spurious output, which
7208 results in failures being hidden.
7209 Use m4_defn where appropriate.
7210 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7211 after the second argument.
7212 Use m4_defn.
7213 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7214 syntax, as it is provided by M4sugar.
7215 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7217 2002-04-03 Andreas Schwab <schwab@suse.de>
7219 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7220 expanded if $# <= 2.

7223 aclocal.
7225 2002-04-03 Akim Demaille <akim@epita.fr>
7227 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

7229 Also recognize *.bb and *.bbg as compilation byproducts.
7230 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7231 (_AC_COMPILER_OBJEXT): Use them.
7232 Fixes Debian #138666.
7234 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7236 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7238 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7239 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7240 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7241 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7242 (AC_C_CONST): Same.

7246 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7247 AC_C_CROSS.

7252 _AS_MKDIR_P_PREPARE.
7254 2002-03-28 Kevin Ryde <user42@zip.com.au>
7256 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7257 to avoid versions of HP C which don't allow that.
7259 2002-03-27 Paul Eggert <eggert@twinsun.com>
7261 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7262 (AS_SHELL_SANITIZE): Invoke it.
7263 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7265 2002-03-26 Akim Demaille <akim@epita.fr>
7267 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
7269 2002-03-26 Akim Demaille <akim@epita.fr>
7271 * doc/autoconf.texi (Introduction): The GNATS base moved.
7273 2002-03-25 Paul Eggert <eggert@twinsun.com>
7275 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7276 as POSIX requires, as it doesn't work with Zsh.
7277 * doc/autoconf.texi (Assignments): Document the problem.
7279 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7281 * doc/autoconf.texi (Limitations of Make): Mention more issue
7282 about VPATH, overriding of macros in sub-makes, and handling of
7283 SHELL.
7285 2002-03-21 Paul Eggert <eggert@twinsun.com>
7287 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7288 problem with here-document buffer boundaries.
7290 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7291 when reinvoking the shell, to work around problems with installers
7292 who put strange things like "cd" commands in their environments.
7294 2002-03-19 Akim Demaille <akim@epita.fr>
7296 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7297 From Aaron Ucko.
7299 2002-03-19 Akim Demaille <akim@epita.fr>
7301 * bin/autoscan.in (scan_file): Specify the location in `&used'
7302 invocations.
7303 From Nicolas Joly.
7305 2002-03-19 Akim Demaille <akim@epita.fr>
7307 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7308 From Nishio Futoshi.
7310 2002-03-19 Akim Demaille <akim@epita.fr>
7312 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7314 2002-03-18 Paul Eggert <eggert@twinsun.com>
7316 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7317 (Limitations of Usual Tools): Add mkdir section.
7319 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7320 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7321 back on AS_DIRNAME to compute prefixes otherwise; this is
7322 roughly what mkinstalldirs does. That way, we need not have
7323 our own filename disassembler. The old disassembler did not
7324 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7326 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7327 Create at_test_all by a series of assignments,
7328 not by a single assignment of a long string. The latter causes ksh
7329 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7330 presumably because of a buffer overrun.
7332 2002-03-14 Paul Eggert <eggert@twinsun.com>
7334 * lib/autotest/general.m4 (at_times_skip):
7335 Renamed from at_times. Now a boolean.
7336 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7337 says 'times: not found'.
7339 2002-03-14 Akim Demaille <akim@epita.fr>
7341 * bin/autoreconf.in (&study_gettextize): New.
7342 (&autoreconf): Handle newest gettextize.
7343 Rerun aclocal if needed.
7344 Suggested by Andreas Schwab.
7346 2002-03-13 Akim Demaille <akim@epita.fr>

7350 2002-03-13 Akim Demaille <akim@epita.fr>
7352 * doc/autoconf.texi (Header Portability): New.
7353 Add information about stdint.h and inttypes.h from Paul Eggert.
7355 2002-03-13 Akim Demaille <akim@epita.fr>
7357 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7358 -p'.
7359 From Bob Proulx.
7361 2002-03-12 Akim Demaille <akim@epita.fr>
7363 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7364 m4_require.
7366 2002-03-11 Andreas Schwab <schwab@suse.de>
7368 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7369 does not do it if --with-lispdir is given.
7371 2002-03-08 Akim Demaille <akim@epita.fr>
7373 Version 2.53.
7375 2002-03-08 Akim Demaille <akim@epita.fr>
7377 * doc/autoconf.texi (Subdirectories): Clarify that the
7378 subdirectory should exist.
7380 2002-03-08 Akim Demaille <akim@epita.fr>
7382 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7384 2002-03-08 Akim Demaille <akim@epita.fr>
7386 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7387 aliases the actual variables, and modifications of the former
7388 affect the latter.
7390 2002-03-08 Akim Demaille <akim@epita.fr>
7392 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7393 because of C-c: have m4 output in tmp files, then mv them.
7395 2002-03-08 Akim Demaille <akim@epita.fr>
7397 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7398 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7399 * bin/ifnames.in: Copyright update.

7403 * doc/autoconf.texi (Invoking autom4te): New.
7405 2002-03-05 Akim Demaille <akim@epita.fr>
7407 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7408 Kevin Ryde.
7410 2002-03-05 Akim Demaille <akim@epita.fr>
7412 Version 2.52i.
7414 2002-03-04 Akim Demaille <akim@epita.fr>
7416 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7417 * lib/autoconf/general.m4 (AC_INIT): More informative error
7418 message for LIBOBJ.
7420 2002-03-04 Akim Demaille <akim@epita.fr>
7422 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7423 parallel builds.
7425 2002-03-04 Akim Demaille <akim@epita.fr>
7427 * doc/autoconf.texi (Transforming Names): Equality between target
7428 and host is irrelevant.
7429 (Specifying Names, Canonicalizing): Remove all references to the
7430 backward compatibility hooks. Rather, collect them all into...
7431 (Hosts and Cross-Compilation): this new section.
7432 * doc/install.texi (System Type): Ditto.
7433 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7434 that `--host' implies cross-compilation.
7436 2002-03-04 Akim Demaille <akim@epita.fr>
7438 * doc/autoconf.texi (Evaluation Macros): New.
7439 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7440 useless.
7441 (_m4_foreach): Define the variant with immediate evaluation so
7442 that it contains exactly the items, not an expression which
7443 evaluation is the current item.
7444 (m4_re_string, m4_re_word): Don't over quote them.
7446 2002-03-04 Akim Demaille <akim@epita.fr>
7448 Instead of having stacking `shift's evaluated at the end, let
7449 `foreach' loops immediately evaluate them.
7451 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7452 $*. This is the n-th time I change my mind, but hopefully this is
7453 the last...
7454 (m4_lquote): New.
7455 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7456 efficient.
7457 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7458 it was only a hack for m4_text_wrap.
7459 (m4_car2): Remove, replaced by...
7460 (m4_cdr): New.
7461 (_m4_foreach): Adjust.
7462 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7463 m4_bpatsubst for clarification.

7507 Fix Autoconf PR/209.
7508 Also reported by Frank Denis.
7510 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
7512 2002-02-07 Akim Demaille <akim@epita.fr>
7514 Fix Autoconf PR/207:
7515 AC_PREFIX_PROGRAM fails with dashed program names
7517 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7518 variable when looking for the prefix program.
7519 Now it also works for shell variables.
7521 2002-02-07 Akim Demaille <akim@epita.fr>
7523 * doc/autoconf.texi (Limitations of Builtins): More about
7524 case/esac.
7526 2002-02-06 Akim Demaille <akim@epita.fr>
7528 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7529 case/esac, some shells don't support it.
7530 Reported by Zack Weinberg.
7531 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7533 2002-02-06 Akim Demaille <akim@epita.fr>
7535 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7536 sure not to introduce newlines in at_groups.
7537 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7539 2002-02-06 Akim Demaille <akim@epita.fr>
7541 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7542 is not available.
7544 2002-02-05 Paul Eggert <eggert@twinsun.com>
7546 * doc/autoconf.texi (Specific Compiler Characteristics):
7547 Describe HP-UX cc bug workaround more accurately.
7548 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7549 not unsigned long.
7550 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7551 cross-compilers, too. This undoes some of the most recent change
7552 to this file.
7554 2002-02-05 Akim Demaille <akim@epita.fr>
7556 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7557 to make sure they are up to date when `check' is run.
7559 2002-02-05 Akim Demaille <akim@epita.fr>
7561 * doc/autoconf.texi (Making testsuite Scripts): Document
7562 package.m4.
7564 2002-02-05 Akim Demaille <akim@epita.fr>
7566 * lib/freeze.mk: New.
7568 2002-02-05 Akim Demaille <akim@epita.fr>
7570 Implement `autom4te --freeze'.
7572 * bin/autom4te.in (&freeze): New.
7573 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7574 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7576 2002-02-05 Akim Demaille <akim@epita.fr>
7578 * bin/autom4te.in (&parse_args): Implement `frozen files are
7579 optional are the sum of the previous files on the command line'.
7580 Also, pass `--reload-state=' on them, so...
7581 (handle_m4): don't.
7582 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7583 (M4sh): Rely on M4sugar.
7584 (Autotest, M4sh, M4sugar): Use frozen files.
7586 2002-01-31 Akim Demaille <akim@epita.fr>
7588 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7589 * doc/autoconf.texi (Initializing configure): Adjust.
7591 2002-01-30 Akim Demaille <akim@epita.fr>
7593 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7594 alphanumeric to `-' instead of `_'.
7596 2002-01-30 Akim Demaille <akim@epita.fr>
7598 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7599 for plain code, the other for cross-compilation code. The latter
7600 is now run with GCC only.
7601 * doc/autoconf.texi (Compilers and Preprocessors): New.
7603 2002-01-30 Akim Demaille <akim@epita.fr>
7605 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7606 values.
7607 * doc/autoconf.texi (Initializing configure): Explain how to
7608 change AC_INIT default values.
7610 2002-01-29 Akim Demaille <akim@epita.fr>
7612 * tests/torture.at (Configuring subdirectories): Use configure.in,
7613 so that aclocal 1.4 works.
7614 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7616 2002-01-28 Akim Demaille <akim@epita.fr>
7618 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7619 needs an argument.
7621 2002-01-28 Akim Demaille <akim@epita.fr>
7623 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7624 AUTOTEST_PATH *after* it was set.
7625 Don't put `.' in the PATH: the user should be precise and `./' if
7626 needed. In addition, given that the test suite does some `cd', if
7627 `.' is in the path, the `tested programs' sections will report
7628 programs found in the test suite's directory, while during the
7629 tests (performed in their own directory), these programs are no
7630 longer visible. In other words, the results is confusing and
7631 useless.
7632 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7634 2002-01-24 Akim Demaille <akim@epita.fr>
7636 Version 2.52g.
7638 2002-01-24 Akim Demaille <akim@epita.fr>
7640 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
7641 * doc/autoconf.texi: Finally add Akim as an author.
7643 2002-01-24 Akim Demaille <akim@epita.fr>
7645 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7646 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7647 Bourne. Use /bin/sh.
7648 From Andreas Buening.
7650 2002-01-24 Akim Demaille <akim@epita.fr>
7652 * config/config.guess, config/config.sub, config/texinfo.tex:
7653 Update from masters.
7655 2002-01-24 Akim Demaille <akim@epita.fr>
7657 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
7658 * config/auxdir.m4, config/cond.m4, config/depend.m4,
7659 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
7660 * config/missing.m4, config/sanity.m4, config/select.m4,
7661 * config/strip.m4: Remove, to ease sync'ing with any version of
7662 Automake.
7664 2002-01-24 Akim Demaille <akim@epita.fr>
7666 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7667 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7668 Reported by Geir Ove Myhr.
7670 2002-01-21 Akim Demaille <akim@epita.fr>
7672 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7674 2002-01-21 Akim Demaille <akim@epita.fr>
7676 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7677 message on invalid options.
7678 * bin/autom4te.in (parse_args): Don't use
7679 Autoconf::General::getopt with non valid options.
7681 2002-01-17 Jim Meyering <meyering@lucent.com>
7683 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7684 $ac_cv_exeext so we don't use an old, invalid, cached value.
7686 2002-01-11 Akim Demaille <akim@epita.fr>
7688 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7689 Meyering.
7690 * doc/autoconf.texi (Function Portability): Document the strnlen
7691 limitation.

7693 * lib/autoscan/functions: Adjust.
7695 2002-01-06 Akim Demaille <akim@epita.fr>
7697 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7698 package.m4, since is really depends upon configure.ac, not
7699 configure.
7700 * doc/autoconf.texi (testsuite Scripts): Adjust.
7701 * tests/Makefile.am (package.m4): New.
7702 EXTRA_DIST it since its a source.
7704 2002-01-06 Akim Demaille <akim@epita.fr>
7706 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7707 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7708 and PACKAGE_BUGREPORT from here...
7709 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7710 arguments.
7711 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7712 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7713 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7714 * tests/tools.at (autoheader): Adjust.
7715 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7717 2002-01-06 Akim Demaille <akim@epita.fr>
7719 * bin/autoscan.in (scan_file): Use `&used'.
7721 2002-01-03 Akim Demaille <akim@epita.fr>
7723 * doc/autoconf.texi (Output): Improved wording regarding use of
7724 AC_OUTPUT.
7725 From Olly Betts.
7727 2001-12-18 Kevin Ryde <user42@zip.com.au>
7729 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7730 sometimes needing writable input.
7732 2001-12-17 Jim Meyering <meyering@lucent.com>
7734 * doc/autoconf.texi (New Macros): Tweak wording.
7736 2001-12-14 Akim Demaille <akim@epita.fr>
7738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7739 trailing files, don't apply `-rf' to files which might not be
7740 created by configure (core, core.*, and *.core), but just `rm -f'.
7741 Suggested by Jonathan Kamens.
7743 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7745 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7747 2001-12-14 Akim Demaille <akim@epita.fr>
7749 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7751 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7753 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7754 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7755 abs_srcdir, top_srcpath to abs_top_srcdir.
7756 (_AC_OUTPUT_FILES): Adjust.
7757 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7758 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7759 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7761 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
7763 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
7764 C/Fortran linking on HP/UX, by extracting the Fortran library
7765 search path from the LPATH line in the $F77 -v output.
7767 2001-12-12 Kevin Ryde <user42@zip.com.au>
7769 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7770 forbidden file descriptors table.
7772 2001-11-26 Akim Demaille <akim@epita.fr>
7774 * bin/autoscan.in (%c_keywords): Build it at top level.
7775 Map to 1 in order to simplify its uses.
7777 2001-11-26 Akim Demaille <akim@epita.fr>
7779 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7780 Remove $filepath, useless.
7781 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7782 variables, they are really part of the tokens.
7783 Split the input line on spaces and then look for tokens.
7784 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7785 because of `lex$U.$(OBJEXT)'.
7786 (&scan_files): Use "@list" instead of join.
7787 * doc/Makefile.am (CLEANFILES): Add *.fns.
7789 2001-11-26 Akim Demaille <akim@epita.fr>
7791 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
7792 Remove, replaced by...
7793 * tests/wrappl.in: Be common for all the Perl executables.
7794 In particular autoscan and autoheader want -I.
7795 * configure.ac: Adjust.
7796 * lib/autoscan/headers: errno.h is portable.
7798 2001-11-26 Akim Demaille <akim@epita.fr>
7800 * bin/autoscan.in (used): New.
7801 Use it.
7803 2001-11-26 Akim Demaille <akim@epita.fr>
7805 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7806 directives.
7807 (&scan_sh_file): Remove a duplicate pattern.
7808 (&check_configure_ac): Use long options.
7809 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
7811 2001-11-26 Akim Demaille <akim@epita.fr>
7813 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
7814 Before, having a line containing the opening of a multi line
7815 comment made the whole line be ignored.
7817 2001-11-26 Akim Demaille <akim@epita.fr>
7819 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7820 (testsuite Scripts): Be one of its subsection.
7821 (Autotest Logs): New.
7823 2001-11-26 Akim Demaille <akim@epita.fr>
7825 Test groups are now run two directories deeper.
7827 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7828 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7829 at_top_builddir.
7830 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7831 top_srcdir, builddir and top_builddir.
7832 Use `at_*dir' relatively to the directory containing the
7833 suite, use `*dir' when relatively to the current group dir.
7835 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7837 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7838 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7839 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7840 spelling errors.
7842 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7844 * doc/autoconf.texi (Using System Type): Add an example of `case
7845 $host' usage so people quit using `case $target' everywhere.
7847 2001-11-22 Akim Demaille <akim@epita.fr>
7849 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7850 spotted by Jim Meyering.
7852 2001-11-16 Paul Eggert <eggert@twinsun.com>
7854 This patch implements a `long double' suggestion by Oliver Kiddle.
7856 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7857 static, to catch errors if the value isn't known at compile-time
7858 and the compiler supports dynamic arrays. Change its name from
7859 `_array_' to `test_array' to avoid potential name clashes.
7860 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7861 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7862 better than double. Catch a bug in GCC 2.95.2 x86.
7863 * doc/autoconf.texi (C Compiler): Document the above.
7864 * NEWS: Likewise.
7866 2001-11-13 Akim Demaille <akim@epita.fr>
7868 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7869 hand.
7870 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7872 2001-11-13 Akim Demaille <akim@epita.fr>
7874 * lib/autotest/general.m4 (AT_INIT): After having run the test
7875 group, go back to the initial directory, not to at_suite_dir.
7877 2001-11-13 Akim Demaille <akim@epita.fr>
7879 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7880 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7881 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7882 option.
7883 (AT_CHECK_CONFIGURE): Use absolute paths.
7884 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7885 The problem is still the old one: there is no means in M4 (that I
7886 know about) to create a defining macro, because there is no means
7887 to create `$1' etc., therefore, the defining macro ``swallows''
7888 all the arguments meant to the defined macro.
7890 2001-11-13 Akim Demaille <akim@epita.fr>
7892 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7893 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7894 configure.ac.
7895 * tests/aclocal.m4: Remove, as it is no longer used.
7897 2001-11-13 Akim Demaille <akim@epita.fr>
7899 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7900 variable names when referring to a single test group, or to
7901 `suite' when referring to the whole test suite.
7902 `at_last_test' is removed: m4 compute at_format itself.
7903 (at_stdout, at_stder1, at_stderr): New variables.
7904 (AT_CHECK): Use them.
7906 2001-11-13 Akim Demaille <akim@epita.fr>
7908 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7909 in PATH.
7910 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7911 Do it as soon as a test fails, don't wait till the end of the test
7912 suite.
7913 Don't remove $as_me.[0-9]*, since these files no longer exist.
7915 2001-11-13 Akim Demaille <akim@epita.fr>
7917 * tests/tools.at: Use absolute paths, since we are no longer run
7918 in place.
7920 2001-11-13 Akim Demaille <akim@epita.fr>
7922 Now that tests are running in their own private dir, there is no
7923 need to list the files to remove at the end of tests groups.
7925 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7926 (AT_data_files, at_data_files): Remove.
7927 (AT_CLEANUP, AT_DATA): Simplify.
7928 (AT_INIT): Adjust.
7929 Remove the group dir if !debug && !failed.
7930 * tests/atspecific.m4: Adjust.
7932 2001-11-13 Akim Demaille <akim@epita.fr>
7934 Start a new layout for Autotest: `testsuite' creates
7935 `testsuite.dir' in which the at-check-line etc. files are to be
7936 found, and `testsuite.dir/003' where the test group 3 is run.
7938 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7939 at_check_line_file, at_format, at_test_normalized, at_group_dir
7940 are new variables.
7941 Create the directories.
7942 Use absolute paths for at- files.
7943 (AT_CHECK): Adjust.
7945 2001-11-11 Michael Matz <matz@kde.org>
7947 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7948 (m4_car2): New.
7949 (m4_car): Properly quote arguments.
7951 2001-11-13 Akim Demaille <akim@epita.fr>
7953 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7954 with stricter rules on LIBOBJS.
7956 2001-11-12 Paul Eggert <eggert@twinsun.com>
7958 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7959 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7960 __PROTOTYPES too.
7962 2001-11-12 Akim Demaille <akim@epita.fr>
7964 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7966 2001-11-12 Akim Demaille <akim@epita.fr>
7968 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7969 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7970 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7971 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7972 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7973 specify to what the macro should be defined (typically to 1).
7975 2001-11-12 Akim Demaille <akim@epita.fr>
7977 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7978 From Jim Meyering.
7980 2001-11-12 Akim Demaille <akim@epita.fr>
7982 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
7983 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
7984 definition used by Automake where LEX is +/- "${missing} lex" and
7985 `missing' itself contains variables.
7987 2001-11-12 Akim Demaille <akim@epita.fr>
7989 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7990 Now that M4sh pushes BODY, the comments were output at the end of
7991 the test suites.
7993 2001-11-08 Akim Demaille <akim@epita.fr>
7995 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7996 that we can trace macros from aclocal.m4.
7997 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7998 obsoleted, and redirect to the former anyway.
7999 Reported by Ralf Corsepius.
8001 2001-11-08 Akim Demaille <akim@epita.fr>
8003 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

8066 (@export_forward_subs): New.
8067 Add basename, dirname, and fileparse.
8068 (@EXPORT): Adjust.
8069 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8070 Don't look for aclocal flags if we already know aclocal is not

8072 Move aclocal.m4t only if it exists.
8073 Reported by Ezra Peisach.
8075 2001-11-03 Akim Demaille <akim@epita.fr>
8077 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8078 passed on command line, defaulting to ./configure.ac if present.
8079 (&maybe_autoreconf, File::Find): Remove, unused.
8080 (&autoreconf): If autoconf is not used, don't try to trace.
8082 2001-11-02 Akim Demaille <akim@epita.fr>
8084 * configure.ac: Bump to 2.52g.
8086 2001-11-02 Akim Demaille <akim@epita.fr>
8088 Version 2.52f.
8090 2001-11-02 Akim Demaille <akim@epita.fr>
8092 * config/config.guess, config/config.sub, doc/standards.texi:
8093 * config/lispdir.m4: Update from masters.

8096 2001-11-02 Akim Demaille <akim@epita.fr>
8098 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8099 Don't run aclocal when aclocal.m4 is not from aclocal.
8100 From Ezra Peisach.
8101 Don't run libtoolize and gettextize if --install is not given.
8103 2001-11-01 Paul Eggert <eggert@twinsun.com>
8105 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8106 be invoked before _AS_LINENO_PREPARE.
8107 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8108 than character ranges.
8110 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8111 invoking AS_BASENAME. Set the locale variables to 'C' if
8112 possible, as POSIX requires this to get the traditional
8113 behavior.
8114 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8116 2001-10-31 Paul Eggert <eggert@twinsun.com>
8118 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8119 with {}, as that triggers a bug in Bash 2.05.
8121 (_AS_LINENO_PREPARE): Use Sed rather than
8122 Awk. Fix the sed prepass to work even if there are multiple
8123 instances of $LINENO on the same line. Do not substitute for
8124 other variables like $LINENOT. Do not check file dates; such a
8125 check is unreliable on sufficiently fast machines, and removing
8126 the check makes the code simpler and more reliable. Check for
8127 output and chmod failures.
8129 * doc/autoconf.texi (Special Shell Variables): Document
8130 the above.
8132 2001-10-31 Akim Demaille <akim@epita.fr>
8134 * tests/Makefile.am (atconfig): Remove this target, Automake
8135 handles it now.
8137 2001-10-31 Akim Demaille <akim@epita.fr>
8139 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8140 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8141 provided, while it is optional.
8142 * configure.ac: Adjust.
8144 2001-10-26 Paul Eggert <eggert@twinsun.com>
8146 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8147 lib/Autom4te/Struct.pm:
8148 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8149 with 5.005_02.
8151 * doc/autoconf.texi (Special Shell Variables): Document some
8152 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8154 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8155 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8156 eval $LINENO is not portable in practice.
8158 2001-10-24 Akim Demaille <akim@epita.fr>
8160 * lib/Autom4te/General.pm (backname): New.
8162 2001-10-24 Akim Demaille <akim@epita.fr>

8169 * doc/autoconf.texi (Shellology): Mention the problems with bash
8170 2.05's use of ANSI quoting in its `set' builtin.
8172 2001-10-22 Paul Eggert <eggert@twinsun.com>
8174 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8175 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8176 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8177 POSIX decided to standardize on the int flavor of strerror_r.
8178 Always do char* test, as there's no reason not to.
8179 Assign to a char* var, to catch strerror_r that returns int*.
8181 * doc/autoconf.texi (Particular Functions):
8182 Document the above changes. Also, document the fact that
8183 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8185 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8187 2001-10-20 Akim Demaille <akim@epita.fr>
8189 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

8195 unchanged, remove the source.

8198 (&autoreconf): Display the full path of the configure.ac we are
8199 studying.
8200 Trace it only once.
8201 Be sure to honor --force with gettextize.
8202 Always run aclocal.
8203 * doc/autoconf.texi: Adjust.
8205 2001-10-20 Akim Demaille <akim@epita.fr>
8207 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8208 Remove, dead.
8209 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8210 `intl' is already present, as it refuses unless --force.
8211 (&parse_args): Use -I, --include instead of the old Autoconf
8212 options.
8213 ($localdir, $autoconf_dir): Remove.
8214 (@include): New.
8215 (&maybe_autoreconf): New, to preserve $_ for File::Find.

8233 From Russ Allbery.
8235 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8237 * bin/autoreconf.in (autoreconf): Display the path to the
8238 configure.ac being studied.
8240 2001-10-18 Paul Eggert <eggert@twinsun.com>
8242 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8243 long, to work around a bug in the HP C compiler version HP92453-01
8244 B.11.11.23709.GP.
8246 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8247 (AS_BASENAME_EXPR): New macro.
8248 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8249 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8250 and fall back on 'sed' only if the other two fail. This makes
8251 AS_BASENAME act more like AS_DIRNAME.
8252 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8253 contains white space.
8254 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8255 Use AS_DIRNAME, since I think it's now DOS-friendly.
8256 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8257 Allow "dirname //FOO" to return either / or //, as POSIX allows
8258 either behavior.
8260 2001-10-10 Akim Demaille <akim@epita.fr>
8262 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

8400 ourselves with CONFIG_SHELL.
8402 2001-10-05 Paul Eggert <eggert@twinsun.com>
8404 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8405 doesn't exist. Remove *.tmp, as a .tmp file is created during the

8477 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
8478 but somehow it didn't get incorporated then.
8479 * doc/autoconf.texi (Limitations of Usual Tools):
8480 Clarify remark about sed and nested parenthesization.
8482 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
8483 Report an error if the size cannot be determined even though
8484 the type exists.
8485 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8486 Check for `expr' arithmetic overflow, and for compilation failure,
8487 and invoke a new argument $4 if either is discovered.
8488 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
8489 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
8491 2001-09-28 Akim Demaille <akim@epita.fr>

8505 2001-09-27 Akim Demaille <akim@epita.fr>

8511 status when executing the ACTION-IF-FALSE.
8512 * tests/base.at (AC_TRY_*): Rename as...

8522 (AC_PROG_CPP requires AC_PROG_CC): here and...
8523 * tests/fortran.at (GNU Fortran 77): there.
8524 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8525 AC_TRY_RUN is about compilation, not shell commands.

8530 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8531 Raja R Harinath:
8532 Be sure to detect when $LINENO always returns the same value.
8533 Look for the original script, basename($0) is certainly not
8534 enough.
8535 Pass the CLI arguments to `$as_me.lineno'.
8537 2001-09-25 Akim Demaille <akim@epita.fr>
8539 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
8540 Be sure the close and reopen the LOG fd before and after using tee

8544 2001-09-23 Akim Demaille <akim@epita.fr>
8546 * bin/autom4te.in (parse_args): There can be several invocations
8547 of --language now.
8549 2001-09-23 Akim Demaille <akim@epita.fr>
8551 * doc/autoconf.texi (Top): Wrap in @ifnottex.
8553 2001-09-23 Akim Demaille <akim@epita.fr>
8555 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
8556 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

8560 the current directory.
8561 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

8563 Skip nonexistent dirs.
8564 * doc/autoconf.texi (Preset Output Variables): Document these
8565 variables.
8567 * lib/autotest/general.m4: Do not reset AT_victims.
8568 Don't compute at_srcdir nor at_top_srcdir.
8570 * tests/tools.at: Hence use top_srcdir.
8572 * tests/Makefile.am, tests/autoconf, tests/autoheader,
8573 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
8574 Remove.

8585 * doc/autoconf.texi (Common Shell Constructs): Rename as...
8586 (Programming in M4sh): this.

8616 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
8618 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
8619 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
8620 to match current versions from CVS Automake.
8622 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

8627 2001-09-22 Akim Demaille <akim@epita.fr>
8629 * lib/autoconf/autotest.m4: Create `package.m4'.
8630 * tests/Makefile.am (package.m4): Remove.
8632 2001-09-22 Akim Demaille <akim@epita.fr>
8634 Rely on `$LINENO' when possible instead of `__oline__'.
8636 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
8637 `$LINENO' support replacement when not supported.
8638 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
8639 them explicitly to be sure they are not output before this section
8640 (via m4_require). Cosmetic only.
8641 * lib/autoconf/c.m4, lib/autoconf/general.m4,
8642 * lib/autoconf/programs.m4: Replace all the occurrences of
8643 `__oline__' with `$LINENO'.
8644 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
8646 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>

8649 character (u: -> ue) in a code comment.
8650 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
8651 it works.
8653 2001-09-21 Akim Demaille <akim@epita.fr>
8655 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
8656 Suggested by Jim Meyering.
8658 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8660 * lib/autoconf/programs.m4: Use extensions listed in
8661 $ac_executable_extensions when looking for programs.

8673 PATH_SEPARATOR.
8674 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
8675 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8676 be used instead of ':'.
8677 * lib/autotest/general.m4: Replace occurrences of ':' in
8678 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
8680 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

8683 arguments. Fixed a typo.
8685 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8687 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8688 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8690 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8692 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
8693 * bin/autoupdate.in: Ditto.
8694 * bin/autoheader.in: Reworded a few comments.

8699 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8701 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8702 already have $file). Set output files to binary mode (helps avoid
8703 CR issues on DOSish systems).
8705 2001-09-19 Akim Demaille <akim@epita.fr>
8707 * lib/autotest/general.m4: Englishoes.
8708 From Tim Van Holder and Alexey Mahotkin.
8710 2001-09-18 Paul Eggert <eggert@twinsun.com>
8712 * doc/autoconf.texi (Common Shell Constructs): New node,
8713 documenting AS_DIRNAME.
8714 (Limitations of Usual Tools): Refer to it when discussing dirname.
8715 Also, update discussion of POSIX standard to reflect latest draft.
8717 * lib/autoconf/c.m4:
8718 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8720 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8721 Do not pass a first argument with leading '-'
8722 to expr, by parenthesizing initial integers that might be negative.
8724 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8725 now merely checks whether it is an error to pass an argument
8726 to getpgrp.
8728 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8729 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8730 whether it is a (compile-time) error to pass an argument to
8731 getpgrp. This simpler test supports the revised documentation,
8732 and is all that AC_FUNC_GETPGRP's users really need.
8734 2001-09-18 Akim Demaille <akim@epita.fr>
8736 * doc/autoconf.texi (Limitations of Make) <$<>: New.
8738 2001-09-18 Akim Demaille <akim@epita.fr>

8744 2001-09-18 Paul Wagland <paul@wagland.net>
8746 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8747 correctly.
8748 Add test for AS_BASENAME.
8749 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8750 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8751 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8752 * tests/base.at: Fixed the expected responses. The old ones were
8753 one line out...
8754 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8755 the documentation claims it should (and how it behaved in 2.13).
8757 2001-09-18 Akim Demaille <akim@epita.fr>
8759 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8760 the AC_CONFIG_COMMANDS invocation.
8761 This also solves the name clash problems.
8762 Don't set the package's ID.
8763 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8764 No longer to be shipped.
8765 (version.in): Remove.
8766 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8767 * lib/autoconf/status.m4: Adjust.
8768 Use `m4_PACKAGE_STRING'.
8769 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8770 the only optional argument is the name of the test suite.
8771 Expect `package.m4' to define the package signature.
8772 * lib/autom4te.in (Autotest): Add `package.m4?'.
8773 * tests/Makefile.am (package.m4): New.
8774 * tests/suite.at: ifnames is a victim.
8776 2001-09-18 Akim Demaille <akim@epita.fr>
8778 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8779 AC_LIBSOURCE, AC_CONFIG_FILES.
8780 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8781 program version string doesn't match the package's.
8782 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8783 after `(cached)'.
8785 2001-09-17 Paul Eggert <eggert@twinsun.com>
8787 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8788 Allow expression to return any value that can fit into unsigned long
8789 (not int, as before). Check for output errors.
8791 2001-09-17 Bruno Haible <haible@ilog.fr>
8793 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8794 Always include <stdio.h> and <stdlib.h>. Evaluate
8795 the expression in an extra function before these includes. Call
8796 fprintf "%d" only after ensuring the argument is of type 'int'.
8797 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8799 2001-09-17 Paul Eggert <eggert@twinsun.com>
8801 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8802 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8803 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8804 when they don't exist.
8806 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8807 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8808 need it.
8810 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8811 version with the version used by fileutils 4.1, except use
8812 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8813 we don't need it.
8815 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8817 2001-09-13 Akim Demaille <akim@epita.fr>
8819 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8820 _first_.
8821 Reported by Gerrit P. Haase.
8823 2001-09-13 Akim Demaille <akim@epita.fr>
8825 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8841 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
8842 Likewise.
8843 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
8844 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
8845 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
8846 AT_tests_all for consistency.

8849 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
8851 2001-09-13 Akim Demaille <akim@epita.fr>
8853 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8855 2001-09-13 Akim Demaille <akim@epita.fr>
8857 * lib/autotest/general.m4 (AT_INIT): Create and remove
8858 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8859 test suites can cohabit.
8861 2001-09-13 Akim Demaille <akim@epita.fr>
8863 * tests/mktests.sh: Don't output banners for empty test files.
8865 2001-09-13 Akim Demaille <akim@epita.fr>
8867 Test suites can be run independently of configure.
8869 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.

8885 * tests/ifnames: New.
8887 2001-09-13 Akim Demaille <akim@epita.fr>
8889 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
8890 test group titles.

8909 (m4_list_append): Remove.
8911 Spread a few keywords in the Autoconf test suite.
8913 2001-09-10 Akim Demaille <akim@epita.fr>
8915 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
8916 PATH_SEPARATOR, let M4sh compute it.
8917 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
8918 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

8931 2001-09-07 Akim Demaille <akim@epita.fr>

8934 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
8935 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
8936 related variables into `at_package_*'.

8939 (AS_MESSAGE_LOG_FD): Define and use it.

8942 at_version.
8944 2001-09-07 Akim Demaille <akim@epita.fr>
8946 Move toward possibly stand-alone test suites.
8948 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
8949 in addition, it introduces useless differences in logs.
8950 (AT_INIT): Let atconfig and atlocal be both optional.
8951 Adjust PATH computation.
8952 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

8962 to avoid GCC warnings.
8963 From Uwe Seimet.
8965 2001-09-05 Akim Demaille <akim@epita.fr>
8967 * bin/autom4te.in: --language is -l, not -s.
8969 2001-09-05 Akim Demaille <akim@epita.fr>
8971 Be ready to handle filenames as stupid as `dnl.at', for if even
8972 the maintainer is dumb enough to do that...
8974 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8975 excellence in M4 quotation: consider `__file__' is active.
8977 And BTW, when invoking m4, pass the --include in the right order:
8978 the wrong one.
8980 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
8981 4m.
8983 2001-09-05 Akim Demaille <akim@epita.fr>
8985 * lib/Autom4te/XFile.pm: New lib file.
8986 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,

8991 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

9001 * doc/autoconf.texi (autoscan Invocation): Adjust.
9003 2001-09-05 Akim Demaille <akim@epita.fr>
9005 CVS GNU M4 doesn't like `undefine(undefined)'.
9007 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9008 New, extracted from main.
9009 Use IO::File wherever possible.
9010 (input.m4): Be constant, use -I instead of hard coding $tmp.
9011 Therefore be a quoted heredoc.
9012 Don't invoke `_au_disable', since ac was not loaded, but just
9013 `unm4.m4'.
9015 2001-08-31 Akim Demaille <akim@epita.fr>
9017 Version 2.52d.
9019 2001-08-31 Akim Demaille <akim@epita.fr>

9022 previous patch.

9025 2001-08-31 Akim Demaille <akim@epita.fr>
9027 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9028 serious problems handling heredocs in heredocs.
9029 Reported by Nicolas Joly.
9031 2001-08-31 Akim Demaille <akim@epita.fr>
9033 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9034 (Making testsuite Scripts): Update.
9036 2001-08-31 Akim Demaille <akim@epita.fr>
9038 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9040 2001-08-31 Akim Demaille <akim@epita.fr>
9042 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9043 (testsuite Scripts): There is no such thing as `atconfig.in'.
9044 And actually one diagram is missing: test suite runtime.
9046 2001-08-31 Akim Demaille <akim@epita.fr>
9048 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9049 inverse order.
9051 2001-08-31 Akim Demaille <akim@epita.fr>
9053 * bin/autoupdate.in (@include): `installcheck' revealed the path
9054 to m4sugar was lacking!
9056 2001-08-31 Akim Demaille <akim@epita.fr>
9058 * man/Makefile.am (.x.1): We really have to pass
9059 autom4te_perllibdir.
9061 2001-08-31 Akim Demaille <akim@epita.fr>
9063 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9064 debug scripts, in particular passing explicitly listed tests to
9065 run is stupid.
9067 2001-08-31 Akim Demaille <akim@epita.fr>
9069 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9070 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9071 Use directly autom4te, not autoconf.
9072 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9074 2001-08-31 Akim Demaille <akim@epita.fr>
9076 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9077 * bin/autoheader.in (%symbol): Strip arguments of macros.

9083 2001-08-31 Akim Demaille <akim@epita.fr>
9085 * bin/autom4te.in (&parse_args): Die on unknown languages.
9086 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9087 need for autoconf.
9088 Promote --include over --macrodir and other obsolete options.
9090 2001-08-31 Akim Demaille <akim@epita.fr>
9092 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9093 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9094 * bin/autom4te.in ($autoconf): Pass --force.
9095 `print $out' doesn't print `$_' but `$out'.
9096 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9097 (autoheader): Pass --force since the test suite goes too fast for
9098 the time stamps.
9099 Adjust to the new autoheader messages.
9101 2001-08-31 Akim Demaille <akim@epita.fr>
9103 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9104 Check the completeness of the #template.

9106 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9107 invocation.
9109 2001-08-31 Akim Demaille <akim@epita.fr>
9111 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9112 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9113 Drop AC_MACRODIR dead for real.
9114 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9115 `autoheader: `config.hin' is created'.
9116 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9118 2001-08-31 Akim Demaille <akim@epita.fr>
9120 * bin/autoheader.in: Rewrite in Perl.
9121 * tests/autoheader: Adjust.
9123 2001-08-31 Akim Demaille <akim@epita.fr>
9125 * bin/autoconf.in (--include, -I): New option.
9126 Map --localdir, --autoconf-dir onto it.
9127 Forward autom4te's options instead of interpreting them.
9128 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9129 There is no such envvar since the inception of autom4te.cfg.
9130 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9131 * bin/autoupdate.in: Adjust, and perform more control.
9132 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9133 * tests/autoconf: Dittowise.
9135 2001-08-31 Akim Demaille <akim@epita.fr>
9137 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9138 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9139 optionally `FILE'.
9140 Use -e, not -f, since /dev/null for instance is OK.
9141 (&parse_args): Adjust.
9142 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9144 2001-08-31 Akim Demaille <akim@epita.fr>
9146 * configure.ac: Also find tested executables in bin.
9147 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9148 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9149 installed peer executables, only PATH is allowed to resolve it.
9150 Pass `autoconf_dir' via options, not via invisible envvars.
9151 * lib/Autom4te/General.pm (&find_peer): Remove.
9152 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9153 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9154 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9155 find the executables for it.
9156 * tests/Makefile.am: Major cleanup. Too lazy to document...
9157 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9158 We only need PERL.
9159 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9160 indeed related to running the test suite, while passing
9161 --autoconf-dir and others is related to running non installed
9162 Autoconf executables. So don't do that, leave it to...
9163 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9164 * tests/autoscan: New.
9165 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9166 refer to library files: rely on --language.
9168 2001-08-29 Akim Demaille <akim@epita.fr>
9170 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9171 s/--set/--language/.
9173 2001-08-29 Akim Demaille <akim@epita.fr>
9175 * doc/autoconf.texi: Strip the @nodes.
9176 Suggested by Paul Eggert.

9179 2001-08-29 Akim Demaille <akim@epita.fr>
9181 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9182 Suggested by Paul Eggert.
9184 2001-08-29 Akim Demaille <akim@epita.fr>
9186 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9187 download in a tmp dir.
9189 2001-08-29 Akim Demaille <akim@epita.fr>
9191 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9192 case insensitive OSes out there :(
9193 From Tim Van Holder.
9195 2001-08-29 Akim Demaille <akim@epita.fr>
9197 * lib/autom4te.in: New.
9198 * lib/Makefile.am (edit, autom4te.cfg): New.
9199 * bin/autom4te.in (BEGIN): Simplify.
9200 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

9202 (&parse_args): Support --mode, --set, and --melt.
9203 * bin/autoconf.in: Simplify and adjust.
9204 * tests/Makefile.am (AUTOMAKE): Use --set.
9205 * tests/atlocal.in: Adjust.
9206 * BUGS: distcheck and check are weak.
9208 2001-08-29 Akim Demaille <akim@epita.fr>
9210 * lib/autotest/general.m4: Use
9211 foo=`(command) 2>/dev/null`
9212 not
9213 foo=`command` 2>/dev/null
9214 (at-devnull): Rename as...
9215 (AT-devnull): this.
9216 (--clean): Remove AT-* files too.
9217 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
9218 Reported by Nicolas Joly.
9220 2001-08-28 Akim Demaille <akim@epita.fr>
9222 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

9232 * lib/autotest/general.m4: Reword some messages.
9233 (AT_INIT): Check for the `times' builtin before using it.
9234 Support test ranges as arguments to the testsuite.
9235 Have -e imply -d as the help text suggested.
9237 2001-08-27 Akim Demaille <akim@epita.fr>
9239 * Makefile.maint: Formatting changes.
9240 (do-po-update, po-update, cvs-update, update): New targets.

9247 Pass it to debug-*.sh scripts.
9248 <AUTOTEST_PATH>: May contain absolute dir names.
9250 2001-08-27 Akim Demaille <akim@epita.fr>
9252 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9253 Support `VAR=VAL' as arguments.
9254 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
9255 may be set via the command line.
9257 2001-08-27 Akim Demaille <akim@epita.fr>
9259 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

9261 first the build dirs, then the src dirs.

9273 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
9274 `ac_top_builddir' to mimic Automake's vocabulary, which much more
9275 readable.
9276 Adjust callers.
9277 * doc/autoconf.texi (Configuration Actions): Document the vars
9278 available in commands.
9279 Emphasize the risks of collisions in init-cmds.

9283 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
9284 (Initializing configure): this new node.
9286 2001-08-27 Akim Demaille <akim@epita.fr>

9309 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
9310 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
9311 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
9312 -> ac_dir).
9313 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
9314 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

9341 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
9342 (AMTAR): Help automake define it.
9343 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
9344 needed, 1.5 can have a macro and a target with the same name.
9345 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
9346 * m4/strip.m4: New.

9361 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9362 the name of the directory they're in, instead of the filename,
9363 since version.m4 is now in m4sugar, but m4_acversion must not be
9364 classified as an Autoconf macro.
9365 ($input_m4): Don't qualify the path to m4sugar.
9366 Rather, pass autoconf_dir to m4.
9367 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

9382 of config.log on traps.
9383 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
9384 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
9385 for config.status'.
9386 Open the log as soon as possible.
9387 Use the same log introduction as configure's.
9389 2001-08-22 Paul Eggert <eggert@twinsun.com>
9391 * doc/autoconf.texi (Indices): New node.
9392 Move indices out of the top level menu and into this submenu.

9396 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9397 AC_TRY_COMMAND.
9398 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
9400 2001-08-22 Akim Demaille <akim@epita.fr>
9402 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

9440 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
9441 can be used.
9443 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
9445 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
9446 program with AC_LANG_PROGRAM before feeding it to
9447 AC_COMPILE_IFELSE. Cleanup grep usage.
9449 2001-08-20 Akim Demaille <akim@epita.fr>
9451 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9452 * NEWS, README, README-alpha, TODO, tests/README: This package is
9453 `Autoconf', not `autoconf' (the executable).
9455 2001-08-20 Akim Demaille <akim@epita.fr>
9457 Info readers seem to need `Index' in the index node title :(
9459 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9460 simplified index node names.
9462 2001-08-20 Akim Demaille <akim@epita.fr>
9464 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
9465 arguments are not literals.

9504 2001-08-20 Akim Demaille <akim@epita.fr>
9506 Huh!?!?! There are still some user EOF tags used, which prevents
9507 their use in AC_CONFIG_COMMANDS for instance...
9509 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
9510 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
9511 `_CSEOF', or `_ATEOF', as appropriate.
9512 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
9513 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

9517 * tests/base.at, tests/m4sh.at, tests/m4sugar.at,
9518 * tests/semantics.at, tests/tools.at, tests/torture.at:
9519 s/^AT_DATA\(([^][]+),/AT_DATA([$1],/.
9521 2001-08-20 Akim Demaille <akim@epita.fr>
9523 Autotest invokes M4sh's initialization.

9568 * doc/install.texi, doc/autoconf.texi: Use `autoconf', not
9569 `autoconf_manual', as texinfo.tex 2001-06-21.10 chokes on it.
9571 2001-08-17 Akim Demaille <akim@epita.fr>
9573 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9574 `$0.log' as for projects where testsuite is in src, we'd have
9575 testsuite.log created in src.
9577 2001-08-17 Akim Demaille <akim@epita.fr>
9579 * bin/autom4te.in (&parse_args): Recognize --normalize.
9581 2001-08-17 Akim Demaille <akim@epita.fr>

9586 (_AC_CHECK_HEADER_OLD, _AC_CHECK_HEADER_MONGREL): New.
9587 (AC_CHECK_HEADER): Use them.
9589 2001-08-17 Akim Demaille <akim@epita.fr>
9591 * doc/autoconf.texi: Work around Texinfo buglets.
9592 (Transformation Rules): One example is enough, users are expected
9593 to have their brains on. And BTW, use DESTDIR.
9594 (dvar): New macro. Use it.
9596 2001-08-17 Akim Demaille <akim@epita.fr>
9598 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
9599 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when
9600 looking for ChangeLogs.
9602 2001-08-17 Akim Demaille <akim@epita.fr>
9604 * bin/autom4te.in: --normalize is a new option.
9605 * bin/autoconf.in: Use it.
9607 2001-08-17 Akim Demaille <akim@epita.fr>

9612 2001-08-16 Paul Eggert <eggert@twinsun.com>
9614 * doc/autoconf.texi, doc/install.texi: Put copyright notice at
9615 start, not at end.
9617 2001-08-15 Akim Demaille <akim@epita.fr>
9619 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
9620 Use it.

9629 (Environment Variables, Output Variables,Preprocessor Symbols)
9630 (Autoconf Macros, M4 Macros, Autotest Macros): these.
9631 * doc/install.texi: Use @command.
9632 (Environment Variables): Rename as...
9633 (Defining Variables): this.
9635 2001-08-15 Akim Demaille <akim@epita.fr>
9637 * doc/autoconf.texi (Function Portability): sprintf's return
9638 value.
9639 From Kevin Ryde.
9641 2001-08-15 Akim Demaille <akim@epita.fr>
9643 * Makefile.maint (CVS): New.
9644 (local-check): Run changelog-check. last.
9645 (alpha): Don't depend upon local-check, since...
9646 (cvs-dist): depends upon it.
9648 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9650 * tests/Makefile.am: Use a clean-local rule to remove
9651 autom4te.cache (it's a directory, not a file.
9652 * Makefile.am: Ditto (but maintainer-clean-local).
9654 2001-08-15 Akim Demaille <akim@epita.fr>
9656 * bin/autom4te.in (@m4_warning): New.
9657 (&handle_m4): Use it.
9658 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9659 warnings are issued at each run.
9660 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9661 is in the src tree.
9663 2001-08-15 Akim Demaille <akim@epita.fr>
9665 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9666 don't waste time running `autoupdate --version' works.
9667 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9669 2001-08-13 Akim Demaille <akim@epita.fr>
9671 * doc/autoconf.texi (ma): Rename this index as...

9684 * lib/autotest/general.m4 (AT_INIT): Log the start/stop dates and
9685 duration of the test suite.
9687 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9689 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
9690 endianness for comparison instead of relying on AT_CHECK_ENV.
9692 2001-08-11 Paul Eggert <eggert@twinsun.com>
9694 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
9695 to the INSTALL file.
9697 2001-08-11 Paul Eggert <eggert@twinsun.com>

9710 2001-08-10 Paul Eggert <eggert@twinsun.com>
9712 * AUTHORS, BUGS, ChangeLog, ChangeLog.0, ChangeLog.1,
9713 ChangeLog.2, GNUmakefile, Makefile.maint, NEWS, README,
9714 README-alpha, TODO, configure.ac, lib/autoconf/Makefile.am,

9719 tests/semantics.at, tests/suite.at, tests/tools.at,
9720 tests/torture.at: Add copyright notice.
9722 * tests/mktests.sh: Update year in copyright notice.
9724 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9726 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9728 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9730 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9731 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9732 * doc/autoconf.texi (C Compiler Characteristics): Update
9733 documentation for AC_C_BIGENDIAN.
9735 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9737 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9738 magic values from an object file when cross-compiling.
9739 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9741 2001-08-10 Akim Demaille <akim@epita.fr>
9743 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9744 effects.
9745 Suggested by Russ Allbery.
9747 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9749 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9750 current $prefix to the sub-configures.
9752 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9754 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9755 extension (needed on BeOS). Reported by Guido van Rossum.
9757 2001-08-09 Akim Demaille <akim@epita.fr>
9759 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9761 2001-08-07 Akim Demaille <akim@epita.fr>
9763 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9764 removed.
9765 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9766 No need to remove the files before and after the each test, before
9767 each test and at the end of the suite is enough.
9768 Display only the children `times', not the shell's.
9769 If the test failed or was skipped, at-times is not available.
9771 2001-08-07 Akim Demaille <akim@epita.fr>
9773 Always produce testsuite.log, including when there are no
9774 failures. This helps getting information on skipped tests, and
9775 duration of the tests. Err, implement the latter btw.
9777 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9778 Dump information on the first run of each test.
9779 (AT_CLEANUP): Create `at-times' containing the duration of the
9780 test group.
9782 2001-08-07 Akim Demaille <akim@epita.fr>
9784 The use of `dumpstat' revealed that `len' was used although it
9785 should not. m4_text_wrap was using it, but in the Autoconf world
9786 where it is legal. Hence (i) test M4sh in its own world, not
9787 Autoconf's, and (ii), ahem, fix the bug :)
9789 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9790 does not like `' instead of [].
9791 (AT_INIT): Forbid `^_?AT_'.
9792 And don't output such tokens.
9793 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9794 `script.as', and `autom4te.cache'.
9795 Remove `empty' and `macro' which are no longer used.
9796 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9797 * tests/m4sugar.at: Use it.
9798 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9800 2001-08-07 Akim Demaille <akim@epita.fr>
9802 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9804 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9806 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9808 2001-08-04 Akim Demaille <akim@epita.fr>
9810 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9811 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9812 AC_TRY_LINK.
9813 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9814 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9815 (AC_F77_MAIN): Likewise.
9817 2001-08-04 Akim Demaille <akim@epita.fr>
9819 Don't rely on M4sugar outputting the patterns in files, since we
9820 might process the output _without_ running m4, hence without these
9821 files.
9823 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9824 * bin/autom4te.in (@Request::includes): Remove, unused.
9825 (@Request::source): Rename as...
9826 (@Request::input): this.
9827 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9828 (&handle_output): Fetch the patterns from the traces.
9829 `$forbidden' and `$allowed' are constant: use m//o.
9830 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9831 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9833 2001-08-04 Akim Demaille <akim@epita.fr>
9835 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9836 autoconf', i.e., in addition to caching traces, cache the output.
9838 * bin/autom4te.in (Request::cache): Rename as...
9839 (Request::id): this.
9840 ($cache, $icache, $tcache, $ocache): New.
9841 (&handle_m4): Save M4 output in the cache instead of $tmp.
9842 (&handle_output): Adjust.
9843 (&up_to_date_p): Check that the output cache is up to date too.
9844 (top level): Run `&handle_m4' iff force or the cache is invalid.
9845 Run `&handle_output' if the output cache is more recent.
9847 2001-08-04 Akim Demaille <akim@epita.fr>
9849 * bin/autom4te.in ($force): New.
9850 (&parse_args, &print_usage): -f, --force is a new option.
9851 (&handle_output): CPP directives might have spaces after `#'.
9852 (&parse_args): The first file only can be frozen.
9854 2001-08-04 Akim Demaille <akim@epita.fr>
9856 Don't let autom4te compute the `include' traces several times:
9857 first check that the trace cache file is up to date, and then
9858 compare its timestamp with that of the output.
9860 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
9861 the preamble. Don't require 5.005 as Autom4te::General does it,
9862 and better yet (use `use', not `require'!).
9863 * lib/Autom4te/Struct.pm: Rename the last occurrences of
9864 Class::Struct as Autom4te::Struct.
9865 * lib/Autom4te/General.pm (File::stat): Use it.
9866 (&mtime): New, export it.
9867 * bin/autom4te.in: Use it.
9868 Declare `$req' is invalid if it is outdated.
