3 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4 ac_config_guess, ac_config_sub, ac_configure.
5 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6 Fix typo that prevented an unnecessary space from being removed.
7 Problems reported by Ralf Wildenhues in:
8 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
12 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
13 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
14 Don't use the term "thread-safe" to talk about mkdir race
15 conditions, since the problem is more a process than a thread
16 issue. Problem reported by Stepan Kasal in:
17 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
18 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
19 the test for 'install' more closely. Look at MKDIR_P first.
20 Look in the PATH, and at /opt/sfw/bin.
21 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
22 Don't bother to try mkdir -p, since we already check mkdir --version;
23 just look at the version number. (There's no easy way to check
24 for race-free implementations.)
25 * tests/tools.at (autoconf: subdirectories): Adjust to above
26 changes, since MKDIR_P now might end in "/mkdir -p".
28 * doc/autoconf.texi (autoheader Invocation): Mention that the
29 first arg of AC_DEFINE_UNQUOTED must not be a literal.
30 Problem reported by Ben Pfaff in
31 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
33 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
34 * doc/autoconf.texi (Special Chars in Variables): New section.
35 (Preset Output Variables): Warn about special chars in CPPFLAGS.
36 (Installation Directory Variables): Quote $(datadir) better.
37 (Limitations of Builtins): Describe some of eval's trickiness.
39 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
40 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
41 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
42 in front of every arg, not just trailing args. Quote apostrophes.
43 (_AC_EVAL_ECHO): New macro.
44 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
45 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
47 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
48 exposed by quoting of eval argument. Put the command on line line
50 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
51 (_AC_PATH_X, AC_PATH_X): Quote more safely.
52 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
53 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
54 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
55 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
57 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
58 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
60 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
61 lines, exposed by quoting of eval argument.
63 2006-05-26 Stepan Kasal <kasal@ucw.cz>
64 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
66 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
67 initialization of `ac_cv_exeext', do not override it if it was
68 already set, unless it was set to `no', for compatibility with
69 Autoconf-2.13, and comment this.
70 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
71 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
72 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
73 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
74 Document that this test may be overridden by setting
77 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
79 Revert these two patches:
81 2006-04-06 Eric Blake <ebb9@byu.net>
82 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
83 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
86 2006-04-01 Stepan Kasal <kasal@ucw.cz>
87 Clean up _AC_COMPILER_EXEEXT* macros.
88 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
89 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
90 ac_file to the name of the default output file and call
91 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
92 initial `rm' of the candidate files...
93 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
94 the same list in subsequent `rm' calls, and for the temporary
95 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
96 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
97 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
98 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
99 no longer needed) by libtool. Make it a cache check.
100 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
101 copied here by mistake.
102 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
104 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
105 _AC_COMPILER_OBJEXT directly.
106 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
108 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
110 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
111 Fix description of how the buggy `sed' works.
113 2006-05-25 Noah Misch <noah@cs.caltech.edu>
117 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
118 ENOLCK. Only mention `make -j' when applicable. Only raise
119 fatal errors when `make -j' is involved. Improve error message.
121 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
123 * doc/autoconf.texi (Here-Documents): We now know more about
124 the variable expansion in here documents bug.
125 Thanks to Tim Rice and Stepan Kasal.
127 * doc/autoconf.texi (Making testsuite Scripts): Add an example
128 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
130 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
132 * tests/autotest.at (Multiline command from M4 expansion):
133 No failure to be expected if the shell quotes newlines in
134 commands in the `set -x' output. Report by Tim Rice.
137 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
139 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
140 expansion in the here-documents used by config.status, as that
141 runs afoul of the Korn shell version M-12/28/93d bug described in
142 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
143 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
144 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
146 2006-05-23 Jim Meyering <jim@meyering.net>
148 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
149 Fix typo introduced with 2006-04-02 change. It reversed the sense
152 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
154 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
155 ac_dB slightly, to save bytes in the script.
156 Max out at 50 lines, rather than 96; this is more likely
157 (though not guaranteed) to avoid obscure 'sed' failures.
159 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
161 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
162 `tr -d -' as bad option argument. Work around this by deleting
163 an unrelated character.
164 Report by Tim Rice <tim@multitalents.net>.
166 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
167 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
168 Stepan Kasal <kasal@ucw.cz>
170 * doc/autoconf.texi (Particular Programs): Do not promise that
171 we always prefer the GNU version of the program, and that we
172 search according to PATH; both rules can have exceptions.
173 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
174 AC_PROG_SED. Move descriptions of limitations
175 to the Limitations of Usual Tools section.
176 (Limitations of Usual Tools) <sed>: Mention script length
177 limitations with Solaris /usr/ucb/sed.
178 <grep>: Fix wording for empty alternative. Mention that -c and
179 -l should not be combined, and that -E and -F should not be
182 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
183 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
185 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
186 limits in Solaris 8 /usr/ucb/sed by testing a long script.
188 2006-05-22 Stepan Kasal <kasal@ucw.cz>
190 * doc/autoconf.texi (Defining Symbols): Literal parameter of
191 AC_DEFINE is now passed to m4_pattern_allow.
192 * NEWS: Mention that; likewise for AC_SUBST.
193 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
194 the parameter to m4_pattern_allow.
195 * tests/tools.at: Add a check for that.
197 2006-05-22 Stepan Kasal <kasal@ucw.cz>
199 * lib/autoconf/status.m4: Fix typos.
201 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
203 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
204 only the files that this macro generates.
206 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
208 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
209 the HP-UX sed limitation of 99 commands, labels do not count.
210 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
212 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
214 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
216 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
217 Import the following fix from coreutils:
219 2006-01-13 Jim Meyering <jim@meyering.net>
221 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
222 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
223 not double-quote uses of that variable, to accommodate the rare
224 case in which getmntent is available in none of the libraries
225 checked. This happens at least on FreeBSD 5.0.
227 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
229 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
230 ac_config_guess, ac_config_sub, and ac_configure, since evidently
231 some other programs unwisely rely on these undocumented vars.
232 But put in warning comments about them.
233 Problem reported by Ralf Wildenhues in
234 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
235 * NEWS: Document that these variables are intended to go away.
237 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
239 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
240 and set the language to C++ (analogous to the equivalent Fortran
243 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
244 * doc/autoconf.texi (C++ Compiler): Document it.
245 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
248 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
250 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
251 that caused config.status to generate 100-command sed scripts; the
252 portable limit is 99.
254 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
256 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
257 variable `ac_d' instead of `d' to avoid infringing namespace.
258 Report by Ralf Menzel.
260 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
262 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
263 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
264 * tests/tools.at (autoconf: subdirectories): New test, taken from
265 the corresponding problem report by Ralf Wildenhues in:
266 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
268 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
269 Quote some uses of shell variables if they might suffer unexpected
270 globbing. This doesn't fix all instances of quoting problems that
271 I found, just the easy ones that look safe.
272 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
273 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
274 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
275 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
276 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
277 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
278 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
280 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
281 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
283 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
285 * bin/autoreconf.in ($help): Reword according to the manual.
286 Suggested by Olly Betts.
288 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
289 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
291 * bin/autoreconf.in: Pass the directory argument to
292 `require_configure_ac'. Fix comment.
293 * tests/torture.at (Configuring subdirectories): Expose this.
294 Reported by Olly Betts.
296 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
298 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
299 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
302 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
303 `$configure_in' instead of `configure.in', to preserve
306 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
308 * config/config.guess, config/config.sub, config/texinfo.tex,
309 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
311 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
313 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
314 test for C99 conformance; (bool) 0.5 is an integer constant
315 expression, but (bool) -0.5 is not. Problem reported by Fedor
316 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
318 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
320 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
321 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
322 Warn about obsolete install-sh files. Remove stray sentence
323 fragment and fix cross reference.
324 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
325 install -d; this undoes the 2006-05-10 change.
326 (MKDIR_P): Mark with AN_MAKEVAR.
327 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
328 that we don't require $INSTALL to be thread-safe. Move comments
329 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
330 of AC_PROG_INSTALL. Output a message saying that we're checking
331 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
332 MKDIR_P instead of AC_SUBST.
333 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
334 Special magic for MKDIR_P, too.
335 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
337 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
339 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
341 Sync from Automake, as follows:
343 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
344 * config/install-sh: Initialize IFS, so field splitting isn't
346 * config/mkinstalldirs: Likewise.
347 * config/missing: Remove superfluous quotes. Replace all uses of
348 `[' by `test', for consistency, and for..
349 * config/missing (sed_minuso, sed_output): New variables.
350 (autom4te, help2man, makeinfo): Use them. Unifies detection of
351 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
352 Fixes `missing' to detect `--output' for help2man. Fixes
353 PR automake/483. Report by Dennis J. Linse.
354 (autom4te): Document in `missing --help'.
356 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
358 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
359 * config/install-sh: Don't use 'path' to talk about file names,
360 as per GNU coding standards. Close a race condition reported by Ralf
361 Wildenhues and Stepan Kasal. There is still a race condition
362 on hosts that predate Posix 1003.1-1992, but we can't help this.
363 Don't mishandle weird characters like space on pre-Posix hosts.
364 Invoke mkdir at most once per dir arg on pre-Posix hosts.
365 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
366 AC_PROG_MKDIR_P from AS_MKDIR_P.
367 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
368 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
369 earlier editions are not (including Automake 1.8.3).
370 Do not suggest mkinstalldirs for thread-safety.
371 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
372 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
373 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
374 presence of special characters and race conditions.
375 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
376 in Autoconf's name space.
378 2006-05-10 Bruno Haible <bruno@clisp.org>
379 and Paul Eggert <eggert@cs.ucla.edu>
381 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
382 from Automake with minor changes.
383 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
385 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
387 * config/install-sh: Update to Automake CVS version, as follows:
388 2006-04-25 Stepan Kasal <kasal@ucw.cz>
389 * lib/install-sh: Simplify the expr implementation of dirname.
390 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
391 * lib/install-sh: Handle --, and diagnose unknown options.
393 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
395 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
396 `./autom4te' to create `./testsuite', since the `all' target
397 will ensure its presence, but `installcheck' should not create
398 the uninstalled wrappers.
400 * tests/torture.at (Unusual Automake input files): Skip if we
401 detect automake < 1.8.
403 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
405 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
406 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
407 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
410 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
412 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
413 munge (multiple) white space and other oddities.
414 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
415 single quotes in variable assignment.
416 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
417 and similar failures by adding multiple spaces, tabs, and other
419 Report and different test suggested by Francesco Romani
420 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
422 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
423 single quotes, we only need to search for single quotes; this
424 both simplifies the search pattern, and makes us less
425 susceptible to `echo' variations for arguments not containing
427 (_AC_ARG_VAR_VALIDATE): Likewise.
429 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
431 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
432 `$*' and IFS concatenation issue with traditional shells and
433 bash-2.04. Report by Seanster@Seanster.com.
435 2006-05-03 Bruno Haible <bruno@clisp.org>
437 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
438 precisely which Mac OS X versions have the od problem.
440 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
442 * doc/autoconf.texi: Use @option systematically.
445 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
446 and Bruno Haible <bruno@clisp.org>
448 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
450 (Integer Overflow): Mention the special case of integer division
453 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
455 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
456 traditional shells like the Solaris one that do not use the
457 first IFS character for assembling `$*'.
458 Prompted by a related report from autoconf_bug@nro.ca.
460 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
461 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

508 (Run Time): Move C exit status stuff to new Exiting Portably section.
509 (Systemology): Mention Posix and levenez. Update v7 reference.
510 (Portable Shell): Mention the Posix shell.
512 2006-04-25 Stepan Kasal <kasal@ucw.cz>
514 * bin/autoconf.as (me): Replace by as_me.
516 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
518 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
519 since as_me isn't set yet.
521 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
523 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
524 a few minor bugs in this area.
526 * doc/autoconf.texi (Programming in M4sh): Comment out the
527 documentation of AS_BASENAME, for now.
528 (Shell Substitutions): Do not use AS_DIRNAME in an example.
529 (Limitations of Builtins) <basename>: Do not refer to
531 * bin/autoconf.as (me): Don't use AS_BASENAME.
532 (dir): Remove the unused variable.
533 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

557 with more accuracy and detail.
559 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
561 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
562 Archive is not officially `GNU' any more. Update URL.

564 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
566 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
568 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
569 newline from the `trap' code to finish `config.log'; the NetBSD
570 /bin/sh resets the exit status after an empty command, as
571 documented in doc/autoconf.texi.
572 Reported by Dalibor Topic <robilad@kaffe.org>.
574 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
576 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
577 Suggested by Bruno Haible.
579 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
581 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
582 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
583 Instead, just list the shells that we know work.
584 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
585 changed. Be more cautious about the _cv_ variable.
586 * tests/tools.at (Syntax of the shell scripts): Check the
587 _cv_ variable once, at first, to avoid an internal autoconf error
588 when sh -n does not work.
590 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
592 * lib/Autom4te/FileUtils.pm: Sync from Automake.
594 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
596 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
597 use ">&-" since we're only 99.999% sure that this is portable,
598 and since the MinGW bug is fixed in a different way.
599 * lib/autotest/general.m4 (AT_INIT): Likewise.
601 2006-04-16 Stepan Kasal <kasal@ucw.cz>
603 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
604 before opening config.log, to avoid hitting a bug on MinGW.
606 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
608 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
609 AS_MESSAGE_LOG_FD before reopening it onto the log file.
610 This works around a MinGW bug reported by Eric Paire.
611 Make sure that all writes to the log file append to it,
612 rather than possibly losing data.
613 * lib/autotest/general.m4 (AT_INIT): Likewise.
615 2006-04-14 Stepan Kasal <kasal@ucw.cz>
617 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
620 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
624 * configure.ac (AC_INIT): Bump to 2.59d.
626 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
630 * Makefile.maint (news-date-check): Do not require a leading `*'
631 before the release date in NEWS.
633 2006-04-12 Stepan Kasal <kasal@ucw.cz>
634 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
636 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
637 the instantiated file do not contain the string 'datarootdir'
638 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
639 @mandir@, replace the reference '${datarootdir}' by the value.
640 * tests/torture.at (datarootdir workaround): New test.
641 * NEWS: Advertise this temporary fixup.
642 Based on a patch by Bruno Haible, reported and analyzed by
643 Paul Eggert and Noah Misch.
645 2006-04-12 Eric Blake <ebb9@byu.net>
647 * tests/autotest.at (Debugging a failed test): Fix comment.
649 2006-04-12 Stepan Kasal <kasal@ucw.cz>
651 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
652 all the changes since 2006-04-07.
654 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
656 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
657 succeeded, but `ln -s file dir' failed, take care to remove the
658 leftover target before the next test, to prevent its spurious
659 failure; also make sure `ln file dir' works before selecting it.
660 Thanks to Keith Marshall for pointing this out.
663 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
664 assignments in `at_debug_args', so that we put them correctly
666 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
667 Reported by Eric Blake.
669 2006-04-11 Eric Blake <ebb9@byu.net>
671 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
672 top-level tests after micro-suite has been run. Used in...
673 (Debugging a successful test, Debugging script and environment),
674 (Debugging a failed test): ...these new tests. The first of these
676 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
677 macro, split out from...
678 (AT_INIT): ...here, so that using -d also generates a run script.
679 Document that -d inhibits top-level logging.
680 * doc/autoconf.texi (testsuite Invocation): Document that -d only
681 inhibits top-level logging; debug scripts are created.
683 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
685 * tests/autotest.at (Empty test, Empty check): New test to check it.
687 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
690 2006-04-10 Stepan Kasal <kasal@ucw.cz>
692 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
693 the files if a problem appears. Make the empty *.at files
694 read-only, too. Proposed by Ralf Wildenhues.
696 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
698 * config/Makefile.am: Add comment to force updated Makefile.in.
700 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
701 space only patch to this file, this patch causes the Makefile.in
702 files that include freeze.mk to be updated, and thus have a
703 newer time stamp again, which in turn makes a pristine CVS
704 checkout have correct time stamps.
706 * Makefile.maint (cvs-sv): New macro, to be used..
707 (config.guess-url_prefix, config.sub-url_prefix)
708 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
709 point to CVS text checkout of Gnulib files.
710 (copyright-check): Bump current year.
711 (announcement): Do not hard-wire `./announce-gen'.
712 (cvs-update): Propagate failures of `cvs' and `move-if-change'
714 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
716 (wget_files): Update config.guess, config.sub, texinfo.tex by
717 `wget-update', now that their URLs work again.
719 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
721 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
722 Problem noted by Paul D. Smith.
724 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 * doc/autoconf.texi: Remove unused words from word list.
727 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
728 .x-sc_trailing_space: New files.
730 * doc/standards.texi: Sync from gnulib.
732 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
733 `LIBOBJDIR' as experimental.
735 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
736 with a target directory; it's internally implemented as `cp'
737 anyway, but since Autoconf advertises the possibility to use
738 a target directory when LN_S is `ln -s', we need to find out.
739 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
740 analyzed by Keith Marshall <keith.marshall@total.com>.
744 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
746 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
747 confdefs.h as-is. In general, if it has backslash-newline or the
748 like, then it doesn't work either to sort or to remove empty
751 2006-04-09 Stepan Kasal <kasal@ucw.cz>
753 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
755 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
757 * lib/autom4te.in (Automake-preselections): Preselect
760 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
762 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
763 apostrophe within a single-quoted string, as this is the usual
764 tradition and is easier to read than '"'"'. Don't rely on the
765 shell treating "$/" like '$/'. Use a more-consistent indenting
768 2006-04-09 Eric Blake <ebb9@byu.net>
770 * tests/autotest.at (Backquote command substitution),
771 (Multiline backquote command substitution): Remove mistaken
772 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
774 (Parenthetical command substitution, Multiline parenthetical
775 command substitution): here.
777 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
779 Import macros from gnulib (often changing their name).
781 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

800 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
801 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
802 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

810 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
811 (C Compiler): Move AC_C_LONG_DOUBLE to ...
812 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
813 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
814 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
815 (Coding Style). Don't mention m4_expand_once.
816 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

836 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
837 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
839 2006-04-08 Stepan Kasal <kasal@ucw.cz>

842 of the warning introduced by the 2001-08-28 change.
844 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
845 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
847 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
848 variables shall be overriden by the cache.
849 * tests/torture.at (AC_ARG_VAR): Test also with a first value
850 that contains braces.
852 2006-04-07 Stepan Kasal <kasal@ucw.cz>
854 Revert the patch from 2006-04-01 and only improve
855 _AS_DETECT_BETTER_SHELL:
857 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
858 skip nonexistent directories.
859 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
860 only shell candidates which exist.
861 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
862 * lib/autotest/general.m4 (AT_INIT): No need to give three
863 parameters to _AS_PATH_WALK.
865 2006-04-07 Stepan Kasal <kasal@ucw.cz>,

868 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
869 distinguish m4sugar macros.
870 * tests/tools.at (autoupdating with aclocal and m4_include):
871 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
872 test case by Noah Misch <noah@cs.caltech.edu>.

886 AS_MKDIR_P exits the script on failure.
887 * lib/autotest/general.m4: Remove redundant AS_ERROR.
889 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
891 * config/elisp-comp, config/install-sh, config/mdate-sh,

907 Paul Eggert <eggert@cs.ucla.edu>,
908 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
910 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
911 whether `set' quotes correctly: redirect stderr of the tested
912 `set', and use a subshell, for Ultrix; use `sed' instead of
913 `grep' for zsh `set' which may write binary output; match only
914 at the beginning of a line, to avoid false positives.
915 In order to avoid false positives by unrelated variables with
916 multiline content, put the dump algorithm in a subshell and
917 unset all variables containing newlines (except some which are
918 special to the shell). Warn about cache variables that are

933 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
934 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
935 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
937 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
938 shell issue with double-quoted command substitutions of native
940 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
943 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1896 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
1897 not portable; thanks to Paul Eggert and Alexandre.
1899 * NEWS: Fix an old typo.
1901 2005-10-20 Jim Meyering <jim@meyering.net>
1903 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
1904 the latter'', in two places.
1906 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
1908 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
1909 AC_LANG_PROGRAM, fixing a typo. Don't give details about
1910 the inner workings of AC_LANG_FUNC_LINK_TRY.
1911 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1912 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1913 by the function rather than ignoring it.
1914 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1915 comparing its address. Intel's interprocedural optimization was
1916 outsmarting the old heuristic. Problem reported by
1919 2005-10-19 Stepan Kasal <kasal@ucw.cz>
1921 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
1923 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>

1926 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
1928 2005-10-04 Stepan Kasal <kasal@ucw.cz>
1930 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
1931 before removing it (chmod -R u+rwx); there are three instances of this.
1933 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1934 Stepan Kasal <kasal@ucw.cz>
1936 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1937 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1938 make its content writable before removing it. Remove an errorneous
1939 comment from the end, where the logs of the failed tests are copied
1940 to the main log file.
1942 2005-09-27 Stepan Kasal <kasal@ucw.cz>
1944 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
1945 in case the computer is too quick. Double quote the configure.ac
1948 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
1949 problems if the testsuite were running too fast.
1951 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1953 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1954 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1955 (which belong to Xt, not X itself). See Debian bug 327655.
1956 * NEWS: Mention this.
1958 2005-09-07 Stepan Kasal <kasal@ucw.cz>
1960 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
1962 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
1964 * config/move-if-change: Don't output "$2 is unchanged";
1965 suggested by Ben Elliston. Handle weird characters correctly.
1967 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1969 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1970 calls, so that the final expansion of this macro is shorter.
1971 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1972 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1973 the cleanup there. Use AS_VAR_* macros, to be more general.
1974 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1976 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1978 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
1980 2005-09-01 Stepan Kasal <kasal@ucw.cz>
1982 * doc/autoconf.texi (Configuration Headers): Add an index entry

1991 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1993 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1994 The previous patch didn't work, so try a better one.
1996 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1998 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1999 in the example. Reported by Bruno Haible.
2000 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2001 "if $undefined_var;" succeeds with my shell.
2003 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2004 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2005 but change the m4_divert_text to m4_divert_once.
2007 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2009 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2010 Work around bug in Solaris /usr/xpg4/bin/awk.
2011 The bug is present in at least Solaris 8 through 10.
2013 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2015 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2016 some evil values and relying on the fact that $* concatenates the
2017 parameters by the first character from IFS.
2019 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2020 Stepan Kasal <kasal@ucw.cz>
2022 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2023 first header appears, define AH_HEADER.
2024 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2025 Update limitations about when to call AC_CONFIG_HEADERS.
2026 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2027 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2028 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2029 ``Configuration Actions''; fix their index entries.
2031 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2032 options correctly. Process N-M as M-N if M is smaller than N.
2033 Process ranges correctly so that N-N will run only N.
2034 Sort and uniquify the tests that will be run. If there is more
2035 than one test, reinsert the banners for the tests.
2036 * tests/autotest.at (Keywords): Unmark XFAIL.
2038 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2040 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2041 before passing the macro name to AH_TEMPLATE.
2043 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2044 now opens log after option processing; in particular, --version
2045 and --help do not touch config.log.
2047 * Makefile.maint: Revert the change from 2005-08-12.
2049 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2057 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2058 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2061 * doc/autoconf.texi (Defining Symbols, Changed Results):
2062 Prepend to LIBS, not append, in examples.
2064 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2066 When building in place, set srcdir="."; suggested by Tim Van Holder.
2068 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2069 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2070 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2071 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2072 does not mean "no --srcdir option".
2074 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2076 * tests/autoscan.at (autoscan): New file.
2077 * tests/suite.at: Use it.

2081 * tests/autotest.at (Keywords): Test keywords combinations.
2083 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2085 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2086 add "2>&1"; gzip 1.2.4 prints help on stderr.
2088 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2090 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2091 was pushdef'ed twice while popped only once. Push it only once.
2092 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2094 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2096 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2097 prefixed by mere "===", not "configure: === ".
2099 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2101 * Makefile.maint: Update from Bison.
2103 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2104 "<tab>" in comment, so that the point is understandable.
2106 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2108 Rewrite substantial part of lib/autoconf/status.m4.
2109 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2110 and CONFIG_COMMANDS are not processed in four separate loops.
2111 Instead, there is one main loop. This alows that the common code
2112 is expanded only once, thus config.status (and configure) is smaller.
2114 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2115 the AC_LIST_FILES and cousins macros are no longer used.
2117 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2118 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2119 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2120 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2121 contain the initialization, nor the for loop, nor the associated
2122 commands; all these go to ...
2123 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2124 _AC_OUTPUT_CONFIG_STATUS.
2125 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2126 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2127 (_AC_OUTPUT_FILE): The creation of the sed script ...
2128 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2129 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2130 _AC_OUTPUT_MAIN_LOOP.
2131 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2132 _AC_CONFIG_COMMANDS): Use ...
2133 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2134 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2135 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2136 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2137 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2138 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2140 (_AC_CONFIG_UNIQUE): Update.
2141 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2142 Replaced by this ...
2143 (_AC_LIST_TAGS): ... new common macro.
2144 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2145 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2146 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2147 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2148 this didn't belong to the `config commands' section.
2149 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2150 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2151 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2152 to the `config commands' section either.
2153 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2154 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2156 ... and many changes to the comments nearby.
2158 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2159 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2160 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2161 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2162 (#define header templates): The comment at the top of the generated
2163 header now includes the name(s) of the source file(s).
2165 Several unrelated small changes:
2167 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2168 parameter to AC_DIAGNOSE.
2169 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2170 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2171 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2172 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2174 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2175 in AC_OUTPUT doesn't double-quote it either.
2176 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2179 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2181 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2182 versions of Portland Group compiler produce single- and double-quoted
2183 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2184 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2186 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2188 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2189 This is a corrected version of yesterday's patch.
2191 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2193 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2194 path, too; insert a "===" to emphasize the line.
2196 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2197 ac_cv_build_alias to ac_build_alias.
2198 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2200 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2201 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2202 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2203 (AC_ARG_VAR): ... here.
2204 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2207 Keep a list of all precious variables and process them with one simple
2208 for loop, instead of expanding all commands, or, OTOH, complicated
2209 processing of output of "set".
2210 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2211 variable names in new macro...
2212 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2213 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2214 a loop to assign all ac_env_* and ac_cv_env_* variables.
2215 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2217 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2218 its value to shell variable ac_precious_vars and call
2219 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2220 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2221 _AC_ARG_VAR_VALIDATE.
2223 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2224 and the AC_SUBSTs ...

2228 the ac_subst_files section in config.log.

2246 Fix my changes from 2005-07-01; reported by Noah Misch.
2247 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2248 description, the macro now accepts only a single tag.
2249 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2251 Fix cases when the varsions of Autoconf and Autotest don't match.
2252 Reported by Noah Misch.
2253 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2254 at_top_builddir, for compatibility with older autotest.
2255 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2256 is not set, use at_top_builddir, for compatibility with older
2257 versions of autoconf.
2259 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2261 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2262 Problem reported by Patrick Welche.
2264 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2266 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2267 sed substitution command, so that we allow | in program prefixes
2268 and program suffixes. (& is a problem anyway; we're not fixing
2270 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2271 configure_input, top_builddir, srcdir, etc.
2272 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2273 PATH_SEPARATOR in AUTOTEST_PATH.
2275 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2277 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2278 for loop over config.site files using `set', to allow
2279 directory names containing IFS characters.
2281 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
2283 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2284 directories with weird names. Apparently some people like living
2285 on the edge. However, improve the test that "pwd" actually does
2286 report a name for the working directory.
2287 * NEWS: Remove the claim that we test for funny chars in dir names.
2289 2005-07-01 Stepan Kasal <kasal@ucw.cz>

2305 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2306 document to output the default config_* lists to config.status.
2307 Don't recognize option --file, if the functionality is not there.
2308 Likewise for --header; moreover, recognize --he and --h as shortcuts
2309 for --help in that case.
2311 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2312 matches the order of execution. No code changed.
2314 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2316 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

2324 2005-06-29 Stepan Kasal <kasal@ucw.cz>

2331 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
2333 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2334 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2335 (AC_SUBST): Call it.
2336 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2337 the directory specific variables; but don't call it for configure_input.
2339 2005-06-28 Derek Price <derek@ximbiot.com>
2341 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2344 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2346 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2347 directory have inherent problems with special characters like spaces,
2348 due to limitations in Make syntax. Problem reported by Alexandre
2350 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
2351 Also, fix Tru64 porting problem with shell patterns,
2352 reported by Ralf Wildenhues.

2360 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
2362 Fix some more shell quoting problems. Prompted by a bug report
2363 from Justace Clutter.
2364 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2365 variable into diagnostic. Make the diagnostic an error, not a warning,
2366 because we really don't support spaces and suchlike in dir names.
2367 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2368 Don't worry about backslashes in srcdir; it can't happen now.
2369 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2370 Simplify ac_optarg handling.
2371 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
2373 2005-06-22 Stepan Kasal <kasal@ucw.cz>
2375 Fix AT_CONFIG_CMP for Solaris hosts; idea from Ralf Menzel.

2378 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
2379 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
2381 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
2382 that '\|' is not allowed in BREs; recommend using newline separated
2383 list of patterns instead of multiple -e options.
2385 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2387 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
2389 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2391 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
2393 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2395 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2396 b, t, r, w commands require single space, while : cannot have any.
2397 (Special Shell Variables): Fix sed code this in the example.
2398 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2399 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2401 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2402 expand to the empty list. Don't use two pairs of m4_changequote,
2405 2005-06-20 Derek Price <derek@ximbiot.com>
2407 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2409 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2411 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2412 * doc/autoconf.texi:
2413 Don't mention Solaris versions so much, if a
2414 problem is common to all extant versions of Solaris. Say "SunOS
2415 4" instead of "SunOS" for SunOS 4.
2416 (awk): Mention more of the limitations of traditional Awk.
2417 (cat): Don't talk about cat -v.

2421 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2422 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
2423 but the implementation is entirely different and is designed
2424 to be compatible with glibc strverscmp.
2425 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2427 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2428 on Mac OS X 10.4 reported by Peter O'Gorman in:
2429 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2430 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2431 Use shell builtins rather than 'expr', to work around expr bug.
2433 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2435 * doc/autoconf.texi: "filesystem" -> "file system".
2436 "behaviour" -> "behavior".
2437 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
2438 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2440 * lib/m4sugar/m4sh.m4: Likewise.
2441 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
2442 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2444 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2445 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2446 to update the man page. That way, we don't have to check in new
2447 man pages every month.
2449 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2450 quotes and backslashes. Patch from Derek Price.

2457 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2459 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2460 -u, since it outputs chatter if the input files are the same.
2461 Problem reported by Ralf Menzel.
2463 2005-06-08 Derek Price <derek@ximbiot.com>
2465 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2466 renaming them since they are about to be redefined anyhow.
2468 2005-06-08 Derek Price <derek@ximbiot.com>
2470 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2471 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2472 Move m4_undefine to alphabetical order.
2474 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2476 * README: Recommend GNU M4 1.4.3 or later.
2477 * doc/autoconf.texi (Introduction): Likewise.
2478 Reword to avoid some formatting glitches.
2479 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2480 Clarify explanation of HP compiler bug.
2481 Redo example output tp match current CVS snapshot.
2482 Use @example.org in email addresses when the examples
2483 might get inadvertently cut-and-pasted into user code.
2484 Remove example of autom4te usage that doesn't seem to work now.
2485 Use modern AC_INIT (except when the example is meant to be
2486 shown with Autoconf 2.13).
2487 Update ksh info for Solaris 9 and later.
2489 Modernize description of Automake versions a bit.
2490 Don't claim a future version of Autoconf is near.
2491 * doc/install.texi: Reword to avoid some formatting glitches.
2493 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2495 * doc/autoconf.texi: Add [] to examples, so that the manual
2496 follows its own advice about quoting better.
2497 Reword to avoid some formatting glitches.
2498 * doc/installt.exi: Reword to avoid some formatting glitches.
2500 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2501 Tru64 ksh pattern matching bug. Reported against Libtool by
2502 Albert Chin <libtool@mlists.thewrittenword.com> and
2503 Nicolas Joly <njoly@pasteur.fr>.
2505 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2507 m4_cdr of one-member list was [[]] (one-member list containing an
2508 empty string) instead of [] (an empty list. Callers were skewed to
2509 match this misbehaviour. As a consequence of this:
2510 - m4_foreach([x], [], [foo]) expanded to `foo', while
2511 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2512 This bug has been fixed:
2514 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2515 expand to an empty string; print error msg if called without
2517 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2518 misbehaviour; handle [] and [[]] correctly.
2520 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2522 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
2523 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
2524 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2526 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2528 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2529 swallow records with more than 99 fields.
2530 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2531 parse the long line.
2533 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2535 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2536 swallow literals longer than 399. Reported by Ralf Wildenhues.
2537 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2538 to workaround this limitation.
2540 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2542 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2543 to gfortran, and make these the first two compiler names
2544 checked (following the general autoconf preference for gcc).
2546 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2548 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2549 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2550 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2552 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2554 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2555 expression of unbounded size when processing the --list
2556 option. This runs afoul of a limit of 399 bytes per regular
2557 expression on AIX. Problem reported by Ralf Wildenhues.
2559 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2561 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2562 * doc/autoconf.texi (Particular Headers): Reword example
2563 for multiline stdbool replacement.
2564 (Setting Output Variables): Reword text a bit. Don't
2565 give all the details about |#_!!_#|.
2566 Reword description of line replacement.
2568 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2570 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2571 now contain newlines, and substituted files must be referenced on
2572 a line alone; the sed scripts to substitute them are now very
2574 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2575 commands can be put in a sed script portably.
2576 * doc/autoconf.texi (Setting Output Variables): Document above
2577 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2578 use of multiline substitution.
2579 * tests/torture.at: No longer expect substitution of newline to fail.
2581 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>

2584 From Ralf Menzel (trivial change).
2586 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2588 * tests/local.at: Don't attempt to check for negated character
2589 classes in shell scripts. The test was too brittle.
2591 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2593 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2594 * doc/autoconf.texi (Limitations of Builtins): Document this
2597 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2599 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2600 common code; used in many places in the tree.
2601 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
2602 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2604 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2606 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2607 messages when ac_unique_file is not found.
2608 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2609 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2610 commands, for consistency with AC_MSG_ERROR and such.
2612 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2614 * bin/Makefile.am: Merge the two rules for creating scripts.

2622 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2624 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2625 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2626 (ac_top_builddir): ... this ...
2627 (ac_top_build_prefix): ... to this; the old name is also kept, for
2628 backward compatibility.
2629 (ac_top_builddir_sub): New variable, without the trailing slash,
2631 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2632 * doc/autoconf.texi (Configuration Actions): Rename
2633 ac_top_builddir to ac_top_build_prefix.
2634 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

2643 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2645 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2646 argument to m4_foreach. I guess it was necessary in the past,
2647 but I think it's a no-op now.
2649 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2651 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2652 ``cat <<_ACEOF'' commands to one.

2657 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2658 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2660 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2661 the wrong patterns between ``case'' and ``esac.'' The previous
2662 code had false positives.

2731 quoting rules. Problems noted by Stepan Kasal.
2732 Also, throughout this document, be more careful about white space.
2733 "blank", "white space", and "space" all have different meanings
2734 and we should be careful to say what we mean.

2785 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2786 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2787 comment and reduce m4_default([foo], []) to [foo].
2788 (m4_strip): Update the explanation.
2790 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2792 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2793 Remove core.conftest.* too; it's generated by Tru64 5.1.
2794 Problem reported by Jennis Pruett.
2795 * lib/autoconf/functions.m4
2796 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2797 Don't bother to remove core files; AC_RUN_IFELSE should do that
2800 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2802 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

2844 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2845 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2846 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2847 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2848 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

2852 * NEWS: The configure command now warns you if you attempt to use
2853 a directory whose name contains a special character like space,

2868 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2869 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2870 ac_pwd, and quote srcdir.
2871 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2873 * doc/autoconf.texi: Fix some systematic formatting problems.
2874 ".)" needs a following @: if not at the end of a sentence, and
2875 similarly for "!)". "etc." should be preceded by a comma.
2876 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2878 2005-03-22 Bruno Haible <bruno@clisp.org>
2880 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

2892 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2893 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2894 from a Common Lisp's `cl'.
2895 (AC_PROG_CXX): Behave according to the documentation: don't
2896 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2897 make the variable CCC precious; use `cl.exe', not `cl'.
2899 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2900 Alexandre Duret-Lutz <adl@gnu.org>
2902 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2903 /dev/null, as "configure" shouldn't read stdin, and this insulates
2904 us from problems (e.g., when testing for "cl"). Also, do this
2905 redirection before invoking "hostname" or "uname", and keep the
2906 original input stream available via...
2907 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2908 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

2920 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2921 newline if neither \c nor -n work, as that would output two
2922 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2924 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2926 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

2930 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2932 Undo previous change, except keep the change to
2933 lib/autoconf/programs.m4 that replaced grep with shell
2934 pattern-matching. This is because net-snmp configure reads stdin.
2935 Reported by Noah Misch.
2937 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2939 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2940 from /dev/null, as "configure" shouldn't read stdin, and this
2941 insulates us from problems (e.g., when testing for "cl").
2942 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2943 before invoking "hostname" or "uname".
2944 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2945 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2946 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2947 "</dev/null" since it's now done at the top of 'configure'.
2948 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2949 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2950 Also, replace grep with shell pattern-matching, to save a process.

2954 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2955 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2956 avoid thinking that Allegro Common Lisp's "cl" command is a C++

2972 * doc/autoconf.texi: Use @acronym for DJGPP.
2973 Fix some @code's that should have been @env's, and vice versa.
2974 Sort environment variable names.
2975 Mention that shells no longer inherit IFS.
2976 Don't recommend PATH_SEPARATOR=';' so strongly.
2977 Mention that $RANDOM might expand to the empty string.
2978 "symlink" and "soft link" -> "symbolic link".

3055 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

3058 2047-byte limit on line length of portable text files.
3059 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3060 Use newline as a separator, not space.

3118 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3119 Update the long comment explaining it.
3121 m4_require no longer writes an ``is required by'' line to the
3122 execution stack. It contains only one bit of non-redundant
3123 information: that the macro was required, not called. And even
3124 this bit is useless in most situations: have you ever met a macro
3125 which both calls and requires the same macro?
3127 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3128 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3133 execution stack; slightly improve the out-of-a-defun error message.
3134 (_m4_divert_grow): New macro, counter for the temporary diversions.
3135 (_m4_require_call): Use it.
3136 * tests/m4sugar.at (m4_require): Expect output without the
3137 ``is required by'' messages.
3139 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

3175 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3176 Warn about newline stripping in `` and $(). Update Solaris
3178 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3179 X insulates us from future changes to Posix.
3180 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3183 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3229 (_m4_divert_n_stack): New macro; the expansion is
3230 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3232 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3233 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3234 stored in _m4_divert_diversion or _m4_divert_dump.
3235 (m4_divert_pop): When the parameter is given, compare the symbolic
3236 name with the last diversion pushed on the stack. Previously, the
3237 current diversion was compared with the numeric value of the
3238 diversion given as the parameter.
3239 (m4_require): If the macro hasn't been expanded yet, call ...
3240 (_m4_require_call): this new macro.

3667 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

3741 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3742 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3743 AT_CHECK_NOESCAPE): Likewise.
3744 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3745 main program): Likewise.
3747 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3749 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

3755 * doc/autoconf.texi (Function Portability): Document isinf and
3756 and isnan. From a suggestion by Kevin Ryde.
3758 * lib/Autom4te/General.pm (END): Return correct exit status even
3759 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3761 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3763 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3764 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3765 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3767 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3769 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3770 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3771 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3772 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3773 * lib/autom4te.in (Automake-preselections): Preselect
3774 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3776 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3778 * lib/autom4te.in (Automake-preselections): Preselect
3779 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3782 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3784 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3786 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3787 Document problem with "`""`" in pdksh POSIX mode.
3789 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3791 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3792 with pdksh, too. Problem reported by Patrick Welche via
3794 * doc/autoconf.texi (Shellology): Note that set -o posix is
3795 useful for pkdsh, too.
3797 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3799 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3800 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3801 Don't fail if ENV or BASH_ENV is readonly.
3802 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3803 etc. are read only. Problem reported by Ludovic Courtes.
3805 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3807 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3808 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3811 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3813 * doc/autoconf.texi (File System Conventions): Warn about
3814 names like "aux". Problem reported by Eric Blake.
3816 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3817 by zero instead of array size, so that we can use any arithmetic
3818 constant expression (instead of requiring an integer constant
3819 expression). This allows us to test expressions like DBL_MAX <
3820 LDBL_MAX, which didn't conform to the C standard using the old
3822 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3823 now that we can do floating-point tests at compile time.
3825 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3827 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3828 and LDBL_EPSILON, as the resulting expression isn't an
3829 integer constant expression and violates the C standard.
3830 Problem reported by Nelson H. F. Beebe. Also, check
3831 for "L" suffix, and check that long double doesn't have
3832 worse range or precision than double, that mixed-mode
3833 arithmetic doesn't generate a diagnostic, that double
3834 constants fit in long double.
3836 2004-06-03 Kevin Ryde <user42@zip.com.au>
3838 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3839 malloc(0) and realloc(NULL,size).
3841 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3844 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3846 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3847 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3850 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3852 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3853 can be rewritten using if-then-else. Suggested by Bruno Haible.
3855 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3857 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3858 Problem reported by Stepan Kasal.
3860 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3862 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3863 change). Patch reported by Ralf Wildenhues in
3864 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3866 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3867 function F exists if the compiler and linker let you compile an
3868 expression like (F != 0). Recent versions of GCC optimize away
3869 the reference to F in that case, since every function address must
3870 be nonzero, so the link succeeds even if F does not exist.
3871 Problem reported by Manu in
3872 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3874 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3875 "Unix". Many uses changed.
3876 (Limitations of Builtins): Explain better why the ! command isn't
3879 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3881 * lib/autom4te.in (Automake-preselections): Preselect
3882 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3884 2004-05-19 Kevin Ryde <user42@zip.com.au>
3886 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3887 referencing AC_FUNC_STRERROR_R.
3889 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3890 note pessimistic assumption when cross compiling.
3892 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3894 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3895 (until 2004) invoked subcommands with sh -e, contra POSIX.
3896 Reported by Kevin Ryde.
3898 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3900 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3901 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3902 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3903 `test -f " /usr/bin/grep"', which _always_ failed.
3904 (AC_PROG_SED): Ditto bogus PATH fix.
3905 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3906 requires that grep correctly supports _multiple_ `-e' options, rather
3907 than stating only that grep should accept `-e'.
3909 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3911 Port to C99, which requires that 'exit' be declared.
3913 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3914 to ensure that stdlib.h is included.
3915 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3916 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3917 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3918 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3919 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3920 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3921 when using 'exit' in a test; C99 requires that 'exit' be declared.
3923 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3925 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3926 now prefers 'grep' implementations that accept -e.
3927 (Limitations of Usual Tools): Describe problems of traditional
3928 egrep and fgrep with long input lines, and of traditional grep
3930 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3931 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3932 All callers changed. Append /usr/xpg4/bin to the PATH, for
3934 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3935 the user with complaints about multiple -e options.
3936 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3937 Define it with AC_PROG_GREP.
3938 * configure.ac (AC_PROG_GREP): Add.
3939 * lib/freeze.mk (GREP): New macro.
3941 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3943 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3944 a possible candidate only after all others fail, rather than
3945 consulting it first. This improves backward compatibility by
3946 better reflecting the way shell selection occurred in previous
3947 versions of Autoconf, and should help to avoid triggering latent
3948 problems in other packages, such as the one in Automake where zsh
3949 is not handled robustly:
3950 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3951 Although it is not Autoconf's responsibility to work around
3952 problems in Automake, it nevertheless makes sense to avoid
3953 introducing unnecessary incompatibilites.
3955 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3956 Gary V. Vaughan <gary@gnu.org>
3958 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3959 how deeply nested we are when a suitable tool is found, set the
3960 ac_path_TOOL_found flag.
3961 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3962 nested we are in this macro. Break out of all 3 nested loops if
3963 ac_path_TOOL_found is set.
3965 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3967 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3968 of the _AS_PATH_WALK loop too if GNU flavor is found.
3970 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3972 * doc/autoconf.texi (Limitations of Make): Update documentation
3973 for `$<'. New entry `Long lines', based on a report from Simon
3974 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3975 paragraph about DJGPP, based on a mail from Richard Dawe.
3977 2004-04-20 Paul Eggert <eggert@twinsun.com>
3979 * tests/c.at (C keywords): Don't assume that GCC supports
3980 "restrict" and "inline", as sufficiently-old GCC versions do not
3981 (also, GCC configured to be in pedantic C89 mode does not).
3982 Problem reported by Sumit Pandya in:
3983 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3985 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3986 consider -g to work if it generates warnings when plain compiles
3987 don't. Problem reported by Braden McDaniel in:
3988 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3990 * doc/autoconf.texi (Slashes): New section, to document a problem
3991 reported by Jim Meyering in:
3992 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3994 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3995 linker output files before linking, to work around IRIX 6 linker bug.
3996 Problem reported by Rainer Orth in:
3997 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3999 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4001 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4002 best tool so far counter rely on the tool path variable name to
4003 avoid checks for one tool being affected by the results of running
4004 the length check on a previous tool.
4006 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4007 match expression argument, as different greps have different
4008 regular expression flavours.
4009 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4011 (AC_PROG_EGREP): Pass 'EGREP$'.
4012 (AC_PROG_GREP): Pass 'GREP$'.
4014 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4016 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4017 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4019 2004-03-29 Paul Eggert <eggert@twinsun.com>
4021 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4022 Types, Specific Compiler Characteristics, System Services,
4023 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4024 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4025 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4026 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4028 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

4039 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4040 now defines HAVE_DECL_TZNAME if it is declared, when
4041 HAVE_STRUCT_TM_TM_ZONE is not defined.
4042 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4043 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

4052 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4054 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4055 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4056 H. F. Beebe for the bug report.
4058 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4060 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4061 quoted -cmdline argument in Portland Group compiler (bug
4062 reported by Jeffrey J. Barteet).

4110 2004-03-03 Paul Eggert <eggert@twinsun.com>
4112 * bin/Makefile.am (edit): Don't use $< in a context where
4113 POSIX doesn't require support for it. Use $@.in instead.
4114 Problem reported by Anthony N. Frasso in
4115 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

4126 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4127 is not always thread-safe. Report from Nathanael Nerode.
4129 2004-02-18 Paul Eggert <eggert@twinsun.com>
4131 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4132 problem on QNX reported by Stephen Rasku in

4144 AC_SUBST provides no portable way to escape literal newlines.
4146 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4147 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4148 Darwin uses -lcrt2.o and there's little point to cataloging all
4149 the system variants. Partial fix reported by Andreas Waechter in:

4166 the behavior of the third argument.
4167 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4168 correctly the behavior of the third argument. Document
4169 what the three macros that AU_DEFUN defines do. Fix
4170 warning message when the third argument includes $0
4171 (reported by Alexandre Duret-Lutz).

4225 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4226 2003 (except 1997) to the list of copyright years. This undoes
4227 the 2003-05-22 change, which removed the older years from the list.
4228 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4230 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4239 egrep and fgrep respectively if $GREP -E/-F don't work.
4240 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4241 _AC_PROG_GREP, and AC_PROG_SED.

4274 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4275 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4276 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4277 not <inttypes.h>. Problem reported by Tim Mooney in
4278 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4279 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4282 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4283 otherwise "make check" fails because it forbids cmp (I guess
4284 because cmp treats files as binary on DOS-like systems).

4287 have changed in 2004.

4299 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4300 -std1 disables some useful extensions on Tru64. Problem reported

4304 2004-01-14 Paul Eggert <eggert@twinsun.com>
4306 * doc/autoconf.texi (Programming in M4sh): Document that
4307 AS_MKDIR_P succeeds if the destination is a symbolic link
4308 to an existing directory.
4309 (Limitations of Usual Tools): Note that mkdir -p might not
4310 succeed on symlinks to directories.
4312 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4314 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

4324 2004-01-10 Jim Meyering <jim@meyering.net>
4326 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4328 2004-01-09 Paul Eggert <eggert@twinsun.com>
4330 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4331 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4332 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4333 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4334 AC_COMPILE_IFELSE, since we now assume our caller invokes
4335 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4336 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4337 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4338 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4340 2004-01-07 Paul Eggert <eggert@twinsun.com>
4342 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4343 `"'...'"`, as it's confusing (and I suspect it may not work on
4344 some platforms). The code was incorrect anyway, as it assumed
4345 that \$ evaluated to itself in that context. Reported by
4346 Alexandre Duret-Lutz.
4348 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4350 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

4383 * Makefile.am (autom4te-update):
4384 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

4400 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4401 -c -o might not work. From a suggestion by Kevin Ryde.
4402 (C Compiler, Generating Sources, Limitations
4403 of Usual Tools, Limitations of Make, Making testsuite Scripts):

4414 Fix typo: mkdir without umask arg.
4416 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4418 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4419 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

4421 explanation clearer.

4432 * tests/atlocal.in: Store the result here.

4684 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
4687 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
4689 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
4690 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
4692 2003-10-10 Andreas Schwab <schwab@suse.de>
4694 * bin/autoheader.in: Avoid empty first line in --version and

4698 2003-10-09 Paul Eggert <eggert@twinsun.com>
4700 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
4701 Issue a more-informative diagnostic.
4702 Problems reported by Eric Sunshine.
4704 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4706 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4707 -mGLOB_options_string stuff for Intel ifc, which can cause
4708 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
4709 pattern-matching instead of grep.
4711 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4713 * doc/autoconf.texi: Document new FC Fortran macros.

4717 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
4718 that future autopoint/aclocal/automake/autoreconf will be able
4719 to trace to find where to install local m4 macros.
4720 * doc/autoconf.texi (Input): Document it.
4723 2003-10-06 Gary V. Vaughan <gary@gnu.org>
4725 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
4726 -lcrtbegin.o to list of ignored flags and fix underquoting of
4729 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
4731 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4732 cache variable instead of $G77 to decide whether to include -O2,
4733 since $G77 is specific to Fortran 77.
4735 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4737 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
4738 free" flag. Re-order flags tested into rough order of popularity.
4740 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4742 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4743 arguments so that it can be used with syntax identical to
4744 AC_PROG_F77, and so that we can more easily decide to
4745 remove/deprecate the DIALECT optional argument in the future if it
4747 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4748 non-freeform-supporting compilers. Document freeform flags.
4750 2003-10-03 Akim Demaille <akim@epita.fr>

4753 Reported by Eric Sunshine.
4755 2003-10-03 Akim Demaille <akim@epita.fr>
4757 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
4758 * bin/autoreconf.in (autoreconf_current_directory): Create the
4759 AUX_DIR if needed, for sake of automake --add-missing etc.
4760 Suggested by Alexandre Duret-Lutz.
4762 2003-10-03 Akim Demaille <akim@epita.fr>
4764 * configure.ac: Quotation and formatting changes.

4798 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
4799 have been created when invoking the compiler.

4810 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
4811 Problem reported by Lars J. Aas in
4812 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4813 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4814 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

4817 2003-09-26 Akim Demaille <akim@epita.fr>
4819 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4820 directory for AC_CONFIG_COMMANDS' first argument exists.
4821 This makes valid the invocation of _AC_SRCPATH that follows.
4822 Reported by Eric Sunshine.
4823 * doc/autoconf.texi (Configuration Commands): Adjust.
4825 2003-09-26 Akim Demaille <akim@epita.fr>
4827 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4828 Reported by Ralf Corsepius.
4830 2003-09-26 Akim Demaille <akim@epita.fr>
4832 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4834 Actually, use AU_ALIAS.
4837 2003-09-26 Paul Eggert <eggert@twinsun.com>
4839 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
4840 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
4841 Problem reported by Eric Sunshine in:

4846 The test suite are sometimes assigning timings incorrectly.
4847 Reported by Henk Krus.
4848 Diagnosed by Nicolas Joly.
4850 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4852 Instead of making AT_help a sequence of assignments to grow
4853 $at_help_all, just make AT_help_all be the growing contents of
4854 $at_help_all, and make a single assignment in...
4856 (at_times_skip): Flip the meaning and rename as...
4858 (AT_INIT): When summarizing the test that ran, remove
4859 $at_times_file after use, and check it is present before trying to

4866 * bin/Makefile.am (edit): Handle '@configure_input@'.
4867 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
4868 (ifnames): chmod -w.
4869 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4870 executables, not bin/ executables! Otherwise all the magic needed
4871 to find non installed files is turned off. This caused a failure
4872 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4873 as found in its environment (sent by tests/autoreconf): pointing
4874 to bin/autom4te that could not find its files.
4875 * tests/mktests.sh: Force the replacement of generated files, for
4876 the sake of "mv" program that are interactive when overwriting a
4878 * config/install-sh: Upgrade from CVS Automake.
4880 2003-09-23 Paul Eggert <eggert@twinsun.com>
4882 * doc/autoconf.texi (Limitations of Builtins): Document test -h
4883 versus test -L issues.
4885 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4886 Paul Eggert <eggert@twinsun.com>
4888 Trivial change to support GCC's configuration procedure.

4924 willing to edit the output files.
4926 2003-09-10 Akim Demaille <akim@epita.fr>
4928 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT

4967 2003-09-04 Akim Demaille <akim@epita.fr>
4969 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
4971 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4973 Add support for newer Fortran dialects. The F77 interface is
4974 unchanged, and continues to support Fortran 77. New FC macros
4975 correspond to all the old F77 macros, with output variables FC,
4976 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4977 available dialect, but older dialects can be specified. There are
4978 new macros AC_FC_SRCEXT to set the source extension, and
4979 AC_FC_FREEFORM to accept free-form source files.
4981 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

5016 * tests/local.at: Require 2.57.
5017 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5018 are defaulted by AT_CHECK anyway.
5019 Use AT_CHECK_AUTOM4TE.

5079 * bin/autom4te.in: Adjust to output the call stack.

5095 Use &verb, not &verbose.
5097 2003-08-21 Akim Demaille <akim@epita.fr>
5099 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5101 ($help): Use Autom4te::ChannelDefs::usage.
5102 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5103 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5105 2003-08-21 Akim Demaille <akim@epita.fr>
5107 First stab at preserving warnings between calls to autom4te,
5108 including when the cache is used.
5110 There are still several issues: (i) there are too many runs of m4
5111 (one for include, one for warnings, and some more), (ii) warnings
5112 spreading on several lines are not handled gracefully, (iii) the
5113 code meant to have the call stack display for errors does not work
5114 (its handling should move from m4 to autom4te).
5116 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5118 (@preselect): Add m4_warn.
5119 ($exit_status): Remove, use $exit_code.
5120 ($help): Use Autom4te::ChannelDefs::usage.
5121 (&handle_m4): No longer define the m4_warnings.
5122 At each run, extract and report the warnings.
5123 Always cache the result, including if the exit status is on
5124 failure, since if nothing changes, we should result in the same
5125 failure, hence we can use the cache.
5126 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5127 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5129 (m4_warn): Redefine as a do-nothing: it is its invocation that
5130 matters, as warnings are now reported via traces.
5131 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5132 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5133 the latter reveals calls to the former.
5137 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5139 2003-08-21 Akim Demaille <akim@epita.fr>

5166 Reported by Alexandre Duret-Lutz.

5170 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5171 * bin/autom4te: Adjust.
5172 In particular, be Autoconf tools are really silent when properly
5173 working, bind the verbosity of the 'note' channel to $verbose.
5174 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5175 (&xsystem, &contents): Remove, since they are exported by...

5234 2003-08-14 Derek Price <derek@ximbiot.com>
5236 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5237 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5238 shorter column three. Add DESCRIPTION to log file content.
5240 2003-08-13 Derek Price <derek@ximbiot.com>
5242 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5245 2003-08-12 Derek Price <derek@ximbiot.com>
5247 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

5258 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5259 in Bash 2.01. Problem reported by Brian Gough in
5260 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5262 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5264 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5265 -lcrt1.o, for OS X. (trivial change)
5267 2003-07-07 Paul Eggert <eggert@twinsun.com>
5269 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5270 inside '#ifndef __cplusplus'. Problem reported by
5273 2003-07-06 Bill Clarke <llib@computer.org>
5275 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5276 'long', not 'int', for benefit of Sun's recent C++ compilers
5277 (trivial change). See:

5284 * lib/Makefile.am (autom4te.cfg): Make it read only.
5285 Depend on Makefile since it contains substitutions.

5288 This change was made on autom4te.cfg which is generated.
5289 Reported by Raja R. Harinath.
5291 2003-06-25 Akim Demaille <akim@epita.fr>
5293 * doc/autoconf.texi (Header Portability): sys/mount.h.
5294 From Gareth McCaughan.
5296 2003-06-23 Akim Demaille <akim@epita.fr>
5298 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5299 not all of them. This fixes 1. the fact that when testing
5300 Autoconf there are many many config.log, 2. the incorrect use of
5301 top_srcdir to find config.log.
5302 Don't mix the detailed output of failed test with the summary of
5303 failures. Rather, append detailed log afterwards.
5305 2003-06-23 Akim Demaille <akim@epita.fr>
5307 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5308 always run: output config.log on $at_group_log.
5310 2003-06-23 Akim Demaille <akim@epita.fr>
5312 * tests/torture.at (#define header templates): Don't use quotes in
5313 C++ comments as it puzzles Emacs' sh font-lock-mode.

5317 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5318 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5319 * tests/atspecific.m4: Rename as...

5324 * doc/autoconf.texi (testsuite Scripts): Adjust.
5326 2003-06-21 Kevin Ryde <user42@zip.com.au>
5328 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5329 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5330 ensuring we add -std1 for full-ANSI.
5332 * doc/autoconf.texi (hdrindex): New macro.
5333 Add index entries for portability of various standard header files.
5335 2003-06-20 Akim Demaille <akim@epita.fr>
5337 * configure.ac: Bump to 2.57b.

5357 Update from masters.
5359 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5361 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5362 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5363 (TEST_SCRIPT): New diversion.
5364 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5365 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5366 (AT_INIT): Support for expected failures.
5368 2003-06-02 Akim Demaille <akim@epita.fr>

5372 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5373 Autoconf nor Automake.
5374 (&contents): New, from Automake.
5377 2003-05-28 Paul Eggert <eggert@twinsun.com>
5379 * NEWS, doc/autoconf.texi (Particular Functions),
5380 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5381 is the inverse of localtime.
5383 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>

5386 (handle_exec_errors): New function. Work around $! being
5387 altered by WEXITSTATUS.
5388 (xqx, xsystem): Use handle_exec_errors.
5390 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5392 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5393 Do not call `_exit()', simply modify `$?'.
5394 (xsystem): Reset $! before running system, and check it afterward.
5395 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5396 63 for version mismatches.
5398 2003-05-23 Akim Demaille <akim@epita.fr>
5400 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5401 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5402 the middle of a line).
5403 * lib/m4sugar/m4sugar.m4: Likewise.
5404 Remove useless spaces in comments.
5406 2003-05-23 Akim Demaille <akim@epita.fr>
5408 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5409 exit 63, so that we (or Automake's "missing") can tell the
5410 difference with a plain failure.
5411 * doc/autoconf.texi (Notices): Adjust.
5413 2003-05-23 Akim Demaille <akim@epita.fr>
5415 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5416 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5417 White spaces cleanup.
5419 2003-05-22 Jim Meyering <jim@meyering.net>
5420 Paul Eggert <eggert@twinsun.com>
5422 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5423 Remove `#include <stdlib.h>' from the list; we should never
5424 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5425 resulting namespace pollution would cause other tests to fail.
5426 Configure scripts run with some older versions of g++ and HP's
5427 aCC would fail due to such an #include. Problems reported by
5428 Matthew Mueller in <http://bugs.debian.org/120704> and by
5430 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5431 In the test, use the test declaration before including <stdlib.h>,
5432 as that's closer to how it'll be used.
5434 2003-05-23 Akim Demaille <akim@epita.fr>
5436 * doc/autoconf.texi (Header Portability): ucred.h.
5439 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5441 Overhaul Autotest's logging: generate separate log files
5442 in testsuite.dir/NNN/testsuite.log, and append them to
5443 testsuite.log instead of re-running the test verbosely.
5445 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5446 file descriptor, write 0 to at_status_file instead of setting
5447 at_status=0, initialize some new variables (at_status_file,
5448 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5449 to rerun the tests, instead append the at_group_log to the
5450 at_suite_log when a test fails.
5451 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5452 with the AS_MESSAGE_LOG_FD redirected to stdout.
5453 (AT_CLEANUP): save the output status in $at_status_file
5454 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5456 (AT_CHECK): since tests are run with a redirected stdout,
5457 and used to be re-run in verbose mode, turn some $at_verbose
5458 into echo, and don't redirect the output of testing stdout
5461 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5462 the name of the debugging directory and information about
5465 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

5499 2003-05-22 Akim Demaille <akim@epita.fr>

5577 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
5579 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
5582 2003-05-06 Akim Demaille <akim@epita.fr>
5584 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5585 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5586 by aclocal.m4 is changed it might require the importing of another
5587 m4 extension file, i.e., aclocal must be run.
5589 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5590 (&parse_args): Use --force with aclocal if required and supported.
5591 (&autoreconf_current_directory): Use &run_aclocal.

5598 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5599 argument instead of a file name, so that the request file remains
5600 open during the whole autom4te run.
5601 ($icache_file): New.
5602 (&freeze): Lock the $icache_file.
5604 2003-04-29 Derek Price <derek@ximbiot.com>
5606 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5607 seperator with m4_append_uniq(). It doesn't work.
5608 (AT_CLEANUP): Add `;' to end of at_help_all.
5609 (AT_INIT): Allow --keywords to be specified more than once. When
5610 grepping $at_help_all for keywords, use the field and keyword
5611 seperators to ensure a complete keyword match. Alter at_prev handling
5612 to support the new --keywords behavior.
5614 2003-04-27 Karl Berry <karl@freefriends.org>
5616 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5617 align better with others. I also made some of the individual
5618 entries on one line, for brevity and to make it easier for me to
5619 sort my dir-example file in the Texinfo distribution :).
5621 2003-04-12 Jim Meyering <jim@meyering.net>
5623 * NEWS: Mention the new macro.

5676 2003-03-29 Akim Demaille <akim@epita.fr>

5686 header causes problems.
5688 2003-03-28 Akim Demaille <akim@epita.fr>
5690 * tests/torture.at (Configuring subdirectories): Require aclocal
5691 1.4, otherwise the test fails, as it does support configure.ac.

5712 2003-03-26 Derek Price <derek@ximbiot.com>
5714 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of

5763 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5764 Tru64 make in the "target lookup" section.
5765 (Automake): Automake 1.5+ no longer requires special tools to be
5766 present on the developer's host.
5768 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
5770 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
5771 to a shell that can handle redirection or quoting correctly.
5772 Override SHELL with the shell detected by configure.
5773 Use of $^O suggested by Tim van Holder.
5774 * bin/autom4te.in (BEGIN): Likewise.

5806 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5807 to fix a mismatch between example and discussion.

5811 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5812 format starting with "-".
5814 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

5821 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5822 compiler says yeah, but preproc says nope, compiler is right.
5823 Conversely, prompt the reader to send a bug report to the
5824 maintainers of the package, not of Autoconf.
5826 2003-02-20 Klee Dienes <kdienes@apple.com>
5828 * bin/autoreconf.in (autoreconf_current_directory): Properly

5833 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
5837 2002-12-23 Paul Eggert <eggert@twinsun.com>
5839 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5840 innocuous variant befor including <limits.h> or <assert.h>. This
5841 works around a bug reported by Albert Chin: HP-UX 11i
5842 (and earlier versions) have a <limits.h> that declares
5843 gettimeofday and many other functions.
5845 2002-12-03 Paul Eggert <eggert@twinsun.com>
5849 * NEWS, configure.ac: Update version.
5851 * doc/fdl.texi: Upgrade to FDL version 1.2.
5853 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5854 nontrivially in main's body, so that f's external declaration is
5855 not optimized away in AIX. This should fix the bug reported by
5857 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5859 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5860 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5861 defined, to support freestanding compilers. This should fix the
5862 bug reported by Momchil Velkov in
5863 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5865 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5866 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

5877 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5878 \(.*\) match is too long and there is something more to be checked.
5879 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

5897 Update from masters.
5899 2002-11-14 Akim Demaille <akim@epita.fr>
5901 * Makefile.maint: Sync with Bison, i.e.:
5902 (po-check): Scan .l and .y files instead of the
5903 .c and the .h files that they generate. This fixes the bug
5904 reported by Tim Van Holder in:
5905 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5906 Look for N_ as well as for _. Try to avoid matching #define for
5910 2002-11-14 Akim Demaille <akim@epita.fr>
5912 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5913 From Paul Eggert and Albert Chin-A-Young.
5915 2002-11-14 Akim Demaille <akim@epita.fr>
5917 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5918 From Paul Eggert and Albert Chin-A-Young.
5920 2002-11-14 Kevin Ryde <user42@zip.com.au>
5922 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5923 than assigning in main, to avoid HP cc +O3 optimizing it away.
5925 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5927 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5928 option. Process --recheck after parsing all options. Pass -q
5929 option to configure on --recheck.
5930 (AC_OUTPUT): Pass -q from configure to config.status.
5931 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5932 arguments to record.
5933 * doc/autoconf.texi (config.status Invocation): Document
5934 config.status -q option.

5961 Reported by Ezra Peisach.
5963 2002-11-05 Akim Demaille <akim@epita.fr>
5965 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5967 We _have_ to stop using the old compatibility scheme that tried to
5968 avoid useless backslashes because Libtool 1.4.3 contains a
5969 AC_DEFINE([error_t], [int],
5970 [Define to a type to use for \`error_t' if it is not
5971 otherwise available.])
5972 We _have_ to quote the single quote and backslashes with \. The
5973 old compatibility scheme saw that ` was backslashed, and therefore
5974 did not quote the single quote. Hence before this patch, Autoconf
5975 was not compatible with Libtool.
5977 2002-11-04 Paul Eggert <eggert@twinsun.com>
5979 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6020 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6021 Make variable, not a shell variable.
6022 Suggested by Bruno Haible.
6024 2002-10-31 Akim Demaille <akim@epita.fr>

6032 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

6059 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6061 sparc_address_test returns void.
6062 Use it with an argument, as prototyped.
6065 2002-10-29 Akim Demaille <akim@epita.fr>
6067 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

6425 From Sam Varshavchik.
6427 2002-10-08 Akim Demaille <akim@epita.fr>
6429 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6430 aclocal invocation, as Gettext macros might not be visible to
6432 Instead of blindly running autopoint, scan configure.ac (not the

6466 * tests/torture.at (Configuring subdirectories): Be robust to
6467 users who use config.site to require for a cache: in this case,

6633 Suggested by Guido Draheim.
6635 2002-09-13 Akim Demaille <akim@epita.fr>
6637 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6638 (chdir_init) might hang when stat'ing mounted directories.
6639 Reported by Vance Shipley.
6641 2002-09-12 Akim Demaille <akim@epita.fr>

6703 precious variables are.
6704 Suggested by Pontus Skoeld.

6708 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6709 (ifnames, autoscan, autom4te): Since we don't only depend on
6710 configure.ac variables (such as VERSION etc.), but also on prefix
6711 and so forth, depend on Makefile, not configure.ac.
6712 Reported by Alexandre Duret-Lutz.

6715 2002-09-05 Kevin Ryde <user42@zip.com.au>

6737 as of today, on Automake's team suggestion.
6739 2002-09-03 Akim Demaille <akim@epita.fr>
6743 2002-09-02 Akim Demaille <akim@epita.fr>
6745 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6747 * configure.ac: Disable SITE_MACRO_DIR.
6749 2002-09-02 Jim Meyering <meyering@lucent.com>
6751 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6752 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6753 Also, tweak grammar: s/make sure to/be sure to/.
6755 2002-09-02 Paul Eggert <eggert@twinsun.com>
6757 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6758 directory names are generally preferable to physical names.
6760 2002-09-02 Akim Demaille <akim@epita.fr>
6762 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6763 Reported by Raja R. Harinath.
6764 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6765 * bin/autoupdate.in: Use error instead of die.
6767 2002-09-01 Paul Eggert <eggert@twinsun.com>
6769 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6770 ordinary shell concatenation rather than echo+tr+sed command that
6771 runs afoul of a long-line-related sed bug in Solaris 8.
6773 * bin/autoheader.in (parse_args): --warning -> --warnings.
6775 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6776 stdout, as traditional "ls" does.
6777 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6778 _AC_COMPILER_EXEEXT_O): Likewise.
6779 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6781 * bin/autoconf.as: Add --prepend-include option. This patch was
6782 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6783 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6785 * bin/autoconf.in, configure: Regenerate.
6787 * doc/autoconf.texi (Special Shell Variables): Mention
6788 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6790 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6791 MAILPATH and set PS1, PS2, PS4 to default values, to work
6792 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6793 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6794 the Autoconf documentation specifies; fall back to "unset" only if
6795 this fails. Use a shell for-loop for this rather than an m4 loop,
6796 to shorten the output script.
6798 2002-08-30 Paul Eggert <eggert@twinsun.com>
6800 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6801 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6802 for the CDPATH problem. Document PWD.
6803 (Limitations of Builtins): Document the problem that "cd $foo" and
6804 "ls $foo" may refer to different directories in shells conforming
6805 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6806 example, since the old example is now out of date.
6808 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6809 FOO" and "ls FOO" talk about different directories; this catches
6810 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6813 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6814 of rolling our own unset.
6815 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6816 in practice we needn't worry about CDPATH if unset doesn't work.
6818 * Makefile.in, aclocal.m4, bin/Makefile.in,
6819 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6820 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6821 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6822 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6823 tests/Makefile.in: Regenerate with Automake 1.6.3.
6825 * config/config.guess, config/config.sub, config/mkinstalldirs:
6828 * configure: Regenerate with self.
6830 2002-08-30 Kevin Ryde <user42@zip.com.au>
6832 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6835 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6837 * bin/autom4te.in (Request::load): Correctly test for "do" read
6840 2002-08-29 Akim Demaille <akim@epita.fr>
6842 * lib/Autom4te/General.pm (&xqx): New.
6843 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6844 hand, which is not portable.
6846 * bin/autom4te.in: Use them.
6847 Use &error instead of die.
6848 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6851 2002-08-17 Paul Eggert <eggert@twinsun.com>
6853 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6854 default list of compilers to try, since it was long ago superseded
6855 by the ksh fc builtin. Suggested by Steven G. Johnson.
6857 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6859 * doc/autoconf.texi (Invoking autom4te): End the option table,
6860 fixing a bug introduced by the previous patch.
6861 (Limitations of Make): Add a 'target lookup' subentry in the
6862 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6864 2002-07-29 Mark D. Roth <roth@feep.net>
6866 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6867 options and use $AUTOM4TE_PATH.
6868 * doc/autoconf.texi: Remove documentation of autom4te
6869 --include-envvar and --site-macro-subdir options and document
6870 use of $AUTOM4TE_PATH.
6871 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6872 arguments from each language section.
6874 2002-07-29 Paul Eggert <eggert@twinsun.com>
6876 * doc/install.texi: Include copyright symbol in copyright notice.
6878 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6880 (AM_MAKEINFOFLAGS): New macro.
6881 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6882 * Makefile.am (INSTALL): Use the new macros.
6883 Use -o rather than --output, since "missing" does not grok --output.
6885 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6887 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6888 comments do not always work. Never trust the exit status of
6891 2002-07-24 Kevin Ryde <user42@zip.com.au>
6893 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6894 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6896 2002-07-23 Paul Eggert <eggert@twinsun.com>
6898 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6899 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6900 apparently treats PATH="nonexistent" as if it contained ".".
6901 Bug reported by Stefan `Sec' Zehl.
6903 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6905 * doc/autoconf.texi (Limitations of Make): Mention the special
6906 handling of the obj/ directory by BSD make.

6936 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
6937 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
6939 2002-07-18 Akim Demaille <akim@epita.fr>,

6942 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
6943 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
6945 2002-07-17 Russ Allbery <rra@stanford.edu>
6947 * doc/autoconf.texi (Initializing configure): Clarify the
6948 description of the tarname default.

7022 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7023 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7024 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7025 so that Emacs setups GNU style for perl-mode and cperl-mode.
7027 2002-06-27 Paul Eggert <eggert@twinsun.com>
7029 * config/install-sh: Quote $src. Prefer || to test's -o option,
7030 as per "Limitations of Builtins".

7032 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7034 * tests/mktests.sh: Use grep instead of fgrep, as per
7035 "Limitations of Builtins".
7037 2002-06-15 Paul Eggert <eggert@twinsun.com>
7039 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7040 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7041 so that we consistently test the just-built programs.
7042 * tests/wrappl.as: Likewise.
7044 2002-06-12 Paul Eggert <eggert@twinsun.com>
7046 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7047 name, so that symlinks to 'autoconf' work properly. Bug reported
7049 * bin/autoheader.in (AUTOM4TE): Likewise.
7050 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7051 * bin/autoscan.in (autom4te): Likewise.
7052 * bin/autoupdate.in (autom4te): Likewise.
7054 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for

7058 2002-06-11 Andreas Schwab <schwab@suse.de>
7060 * doc/autoconf.texi: Add more dir entries.
7062 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7064 * bin/autom4te.in ($cache): Don't define using `$me', the name
7065 of the cache should not depend on the name under which autom4te
7068 2002-06-07 Akim Demaille <akim@epita.fr>
7070 * tests/tools.at (autoconf: forbidden tokens, basic)
7071 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7072 words in autom4te.in.
7074 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

7079 2002-06-07 Akim Demaille <akim@epita.fr>
7081 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7083 (AC_REPLACE_FNMATCH): this.
7084 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7085 AC_FUNC_FNMATCH_GNU.
7087 2002-06-07 Akim Demaille <akim@epita.fr>
7089 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7090 Rosetta Stone for Unix.
7092 2002-06-07 Akim Demaille <akim@epita.fr>
7094 * bin/autom4te.in (warn_forbidden): When rejecting a token,

7096 Suggested by Adam J. Richter.
7098 2002-06-07 Akim Demaille <akim@epita.fr>
7100 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

7110 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7111 * tests/mktests.sh (ac_exclude_list): Don't check

7114 2002-06-06 Paul Eggert <eggert@twinsun.com>
7116 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7119 * doc/autoconf.texi (Configuration Links): Likewise.

7147 2002-05-27 Paul Eggert <eggert@twinsun.com>
7149 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7150 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7151 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7152 instead of AC_MBSTATE_T, which never existed.
7154 2002-05-23 Akim Demaille <akim@epita.fr>
7156 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7157 version of Autoconf that is discussed.
7159 2002-05-22 Paul Eggert <eggert@twinsun.com>
7161 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7162 from the default list of compilers to try. Suggested by
7164 * NEWS: Document the above.
7165 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7167 2002-05-17 Paul Eggert <eggert@twinsun.com>
7169 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7170 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7171 This improves on an earlier suggestion by H. Peter Anvin.
7173 2002-05-16 Paul Eggert <eggert@twinsun.com>
7175 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7176 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7177 Both macros now accept an optional source-dir arg.
7178 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7180 * NEWS: Document this.
7181 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7183 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7184 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7185 not for GNU extensions; this undoes part of the 2000-11-03 change,
7186 reverting to 2.13-compatible behavior.
7187 Add new optional argument DIR.
7188 (AC_FUNC_FNMATCH_GNU): New macro.
7190 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7192 2002-05-08 Paul Eggert <eggert@twinsun.com>
7194 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7195 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7196 and it causes a 'test' syntax error if it fails.
7197 Bug reported by Stephen Gildea.
7199 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7200 If prototypes are supported, use them to check this at compile-time,
7201 instead of trying to check it at run-time. If we must do a run-time
7202 check, assume that setvbuf is standard when cross-compiling, as
7203 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7204 Bug reported by Paul D. Smith.
7206 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7207 argument specifying location of getloadavg.c. This removes a
7208 FIXME. This idea was taken from Jim Meyering's implementation in
7210 * doc/autoconf.texi (Particular Functions): Document this.
7211 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7212 that's what the code does; this fixes a bug reported by
7215 2002-05-03 Akim Demaille <akim@epita.fr>
7217 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7218 autopoint instead of gettextize.
7219 ($uses_alocal): Rename as...
7220 ($uses_aclocal): this.
7221 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7222 Suggested by Bruno Haible.
7224 2002-05-03 Akim Demaille <akim@epita.fr>
7226 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.

7230 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7231 files to be 1 second older; just set them to be the same time.
7232 Also, sleep 1 second after the first aclocal, to work around
7233 problems with sub-second time stamps on the input files.
7235 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7237 * doc/autoconf.texi: Mention "set -e -x" lossage

7244 From Christian Cornelssen.
7246 2002-04-29 Akim Demaille <akim@epita.fr>
7248 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7249 of lack of $LINENO support, then the test will compare the $LINENO
7250 in testsuite vs. the lineno in the test file. This is wrong, of
7252 Be sure to protect it.
7253 Reported by Patrick Welche.
7255 2002-04-25 Akim Demaille <akim@epita.fr>
7257 * doc/autoconf.texi (Obsolete Macros): Typo.
7258 Reported by Vladimir Volovich.
7260 2002-04-25 Akim Demaille <akim@epita.fr>
7262 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7263 than some of the input files, hence, on the second run of aclocal,
7264 if some of its input are younger, make them older.
7265 Suggested by Paul Eggert.
7267 2002-04-25 Akim Demaille <akim@epita.fr>
7269 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

7275 and ac_subst_vars be sh variables containing the list of
7276 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7278 (_AC_INIT_PREPARE): Use them to log them.
7279 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7280 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7281 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7282 _AC_SUBST_FILES and _AC_SUBST_VARS.
7283 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7285 2002-04-24 Akim Demaille <akim@epita.fr>
7287 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7288 autoheader, so that automake does not complain about a missing
7289 config.h.in that was to be created.
7291 2002-04-23 Akim Demaille <akim@epita.fr>
7293 * bin/autoheader.in (parse_args): --warning takes an argument.

7343 Minor spelling and grammar fixes.
7345 * doc/autoconf.texi: Follow the outline suggested in the GNU
7346 Sample Texts sections of the Texinfo 4.2 manual. Most
7347 importantly, this makes sure that the copyright notices appear in
7348 all output formats. You probably need Texinfo 4.2 to generate

7375 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7377 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7378 from aclocal.m4 too.

7386 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7387 workaround for ${1+"$@"}.
7388 * doc/autoconf.texi (Shell Substitutions): Explain it.
7389 From Oliver Kiddle and Peter Stephenson.
7391 Have M4sh perform minimal shell sanitizing.
7393 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7395 (_AS_PREPARE): this new macro.
7397 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7398 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7400 Adjust Autoconf and Autotest.
7402 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7403 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7404 * lib/autotest/general.m4 (AT_INIT): Likewise.
7405 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7406 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7409 Use this M4sh to generate Autoconf's shell scripts.
7411 * tests/wrapsh.as: New, precursor of wrapsh.in.
7412 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7413 on Autotest and M4sh.
7414 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7415 (wrapsh.in): New target.
7416 * bin/autoconf.as: New, precursor of autoconf.in.
7417 (autoconf.in): New target.
7419 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7422 with indented comments in rules.

7426 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7427 ac_top_builddir when setting ac_abs_top_builddir.
7429 2002-04-06 Kevin Ryde <user42@zip.com.au>
7431 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.

7437 directories when descending in a SUBDIRS.
7438 Reported by Ezra Peisach.
7440 2002-04-04 Andreas Schwab <schwab@suse.de>
7442 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7443 contains no literal separators.
7445 2002-04-03 Akim Demaille <akim@epita.fr>
7447 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7448 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7449 Use dnl, not the KILL diversion.
7451 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7452 (AC_CONFIG_LINKS): here.
7454 Don't use the KILL diversion, as it kills spurious output, which
7455 results in failures being hidden.
7456 Use m4_defn where appropriate.
7457 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7458 after the second argument.
7460 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7461 syntax, as it is provided by M4sugar.

7486 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7487 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7488 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.

7506 2002-03-27 Paul Eggert <eggert@twinsun.com>
7508 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7509 (AS_SHELL_SANITIZE): Invoke it.
7510 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7512 2002-03-26 Akim Demaille <akim@epita.fr>
7514 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.

7526 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

7529 about VPATH, overriding of macros in sub-makes, and handling of
7532 2002-03-21 Paul Eggert <eggert@twinsun.com>
7534 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7535 problem with here-document buffer boundaries.
7537 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7538 when reinvoking the shell, to work around problems with installers
7539 who put strange things like "cd" commands in their environments.
7541 2002-03-19 Akim Demaille <akim@epita.fr>

7564 (Limitations of Usual Tools): Add mkdir section.
7566 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7567 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7568 back on AS_DIRNAME to compute prefixes otherwise; this is
7569 roughly what mkinstalldirs does. That way, we need not have
7570 our own filename disassembler. The old disassembler did not
7571 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7573 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7574 Create at_test_all by a series of assignments,
7575 not by a single assignment of a long string. The latter causes ksh
7576 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7577 presumably because of a buffer overrun.
7579 2002-03-14 Paul Eggert <eggert@twinsun.com>
7581 * lib/autotest/general.m4 (at_times_skip):
7582 Renamed from at_times. Now a boolean.
7583 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7584 says 'times: not found'.

7634 aliases the actual variables, and modifications of the former
7637 2002-03-08 Akim Demaille <akim@epita.fr>
7639 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7640 because of C-c: have m4 output in tmp files, then mv them.
7642 2002-03-08 Akim Demaille <akim@epita.fr>
7644 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

7674 * doc/autoconf.texi (Transforming Names): Equality between target
7675 and host is irrelevant.
7676 (Specifying Names, Canonicalizing): Remove all references to the
7677 backward compatibility hooks. Rather, collect them all into...
7678 (Hosts and Cross-Compilation): this new section.
7679 * doc/install.texi (System Type): Ditto.
7680 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7681 that `--host' implies cross-compilation.
7683 2002-03-04 Akim Demaille <akim@epita.fr>
7685 * doc/autoconf.texi (Evaluation Macros): New.
7686 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7688 (_m4_foreach): Define the variant with immediate evaluation so
7689 that it contains exactly the items, not an expression which
7690 evaluation is the current item.
7691 (m4_re_string, m4_re_word): Don't over quote them.
7693 2002-03-04 Akim Demaille <akim@epita.fr>
7695 Instead of having stacking `shift's evaluated at the end, let
7696 `foreach' loops immediately evaluate them.
7698 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7699 $*. This is the n-th time I change my mind, but hopefully this is
7702 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7704 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7705 it was only a hack for m4_text_wrap.
7706 (m4_car2): Remove, replaced by...
7708 (_m4_foreach): Adjust.
7709 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7710 m4_bpatsubst for clarification.

7762 AC_PREFIX_PROGRAM fails with dashed program names
7764 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7765 variable when looking for the prefix program.
7766 Now it also works for shell variables.
7768 2002-02-07 Akim Demaille <akim@epita.fr>
7770 * doc/autoconf.texi (Limitations of Builtins): More about
7773 2002-02-06 Akim Demaille <akim@epita.fr>
7775 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7776 case/esac, some shells don't support it.
7777 Reported by Zack Weinberg.
7778 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7780 2002-02-06 Akim Demaille <akim@epita.fr>
7782 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7783 sure not to introduce newlines in at_groups.
7784 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7786 2002-02-06 Akim Demaille <akim@epita.fr>
7788 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7791 2002-02-05 Paul Eggert <eggert@twinsun.com>
7793 * doc/autoconf.texi (Specific Compiler Characteristics):
7794 Describe HP-UX cc bug workaround more accurately.
7795 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7797 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7798 cross-compilers, too. This undoes some of the most recent change
7801 2002-02-05 Akim Demaille <akim@epita.fr>
7803 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7804 to make sure they are up to date when `check' is run.
7806 2002-02-05 Akim Demaille <akim@epita.fr>
7808 * doc/autoconf.texi (Making testsuite Scripts): Document
7811 2002-02-05 Akim Demaille <akim@epita.fr>
7813 * lib/freeze.mk: New.
7815 2002-02-05 Akim Demaille <akim@epita.fr>
7817 Implement `autom4te --freeze'.
7819 * bin/autom4te.in (&freeze): New.
7820 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7821 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7823 2002-02-05 Akim Demaille <akim@epita.fr>
7825 * bin/autom4te.in (&parse_args): Implement `frozen files are
7826 optional are the sum of the previous files on the command line'.
7827 Also, pass `--reload-state=' on them, so...
7829 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7830 (M4sh): Rely on M4sugar.
7831 (Autotest, M4sh, M4sugar): Use frozen files.
7833 2002-01-31 Akim Demaille <akim@epita.fr>
7835 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7836 * doc/autoconf.texi (Initializing configure): Adjust.
7838 2002-01-30 Akim Demaille <akim@epita.fr>
7840 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7841 alphanumeric to `-' instead of `_'.
7843 2002-01-30 Akim Demaille <akim@epita.fr>
7845 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7846 for plain code, the other for cross-compilation code. The latter
7847 is now run with GCC only.
7848 * doc/autoconf.texi (Compilers and Preprocessors): New.
7850 2002-01-30 Akim Demaille <akim@epita.fr>
7852 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

7855 change AC_INIT default values.
7857 2002-01-29 Akim Demaille <akim@epita.fr>
7859 * tests/torture.at (Configuring subdirectories): Use configure.in,
7860 so that aclocal 1.4 works.
7861 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7863 2002-01-28 Akim Demaille <akim@epita.fr>
7865 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7868 2002-01-28 Akim Demaille <akim@epita.fr>
7870 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7871 AUTOTEST_PATH *after* it was set.
7872 Don't put `.' in the PATH: the user should be precise and `./' if
7873 needed. In addition, given that the test suite does some `cd', if
7874 `.' is in the path, the `tested programs' sections will report
7875 programs found in the test suite's directory, while during the
7876 tests (performed in their own directory), these programs are no
7877 longer visible. In other words, the results is confusing and
7879 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7881 2002-01-24 Akim Demaille <akim@epita.fr>

7892 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7893 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7894 Bourne. Use /bin/sh.
7895 From Andreas Buening.
7897 2002-01-24 Akim Demaille <akim@epita.fr>
7899 * config/config.guess, config/config.sub, config/texinfo.tex:
7900 Update from masters.
7902 2002-01-24 Akim Demaille <akim@epita.fr>
7904 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

7913 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7914 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7915 Reported by Geir Ove Myhr.
7917 2002-01-21 Akim Demaille <akim@epita.fr>
7919 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7921 2002-01-21 Akim Demaille <akim@epita.fr>
7923 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7924 message on invalid options.
7925 * bin/autom4te.in (parse_args): Don't use
7926 Autoconf::General::getopt with non valid options.
7928 2002-01-17 Jim Meyering <meyering@lucent.com>
7930 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7931 $ac_cv_exeext so we don't use an old, invalid, cached value.
7933 2002-01-11 Akim Demaille <akim@epita.fr>
7935 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7937 * doc/autoconf.texi (Function Portability): Document the strnlen
7939 (Particular Functions): Document AC_FUNC_STRNLEN.
7940 * lib/autoscan/functions: Adjust.
7942 2002-01-06 Akim Demaille <akim@epita.fr>
7944 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7945 package.m4, since is really depends upon configure.ac, not
7947 * doc/autoconf.texi (testsuite Scripts): Adjust.
7948 * tests/Makefile.am (package.m4): New.
7949 EXTRA_DIST it since its a source.
7951 2002-01-06 Akim Demaille <akim@epita.fr>
7953 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7954 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7955 and PACKAGE_BUGREPORT from here...
7956 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7958 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7959 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7960 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7961 * tests/tools.at (autoheader): Adjust.
7962 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7964 2002-01-06 Akim Demaille <akim@epita.fr>
7966 * bin/autoscan.in (scan_file): Use `&used'.
7968 2002-01-03 Akim Demaille <akim@epita.fr>
7970 * doc/autoconf.texi (Output): Improved wording regarding use of
7974 2001-12-18 Kevin Ryde <user42@zip.com.au>
7976 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7977 sometimes needing writable input.

7983 2001-12-14 Akim Demaille <akim@epita.fr>
7985 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7986 trailing files, don't apply `-rf' to files which might not be
7987 created by configure (core, core.*, and *.core), but just `rm -f'.
7988 Suggested by Jonathan Kamens.
7990 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7992 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7994 2001-12-14 Akim Demaille <akim@epita.fr>
7996 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7998 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8000 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8001 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8002 abs_srcdir, top_srcpath to abs_top_srcdir.
8003 (_AC_OUTPUT_FILES): Adjust.
8004 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8005 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8006 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8008 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8010 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8011 C/Fortran linking on HP/UX, by extracting the Fortran library
8012 search path from the LPATH line in the $F77 -v output.
8014 2001-12-12 Kevin Ryde <user42@zip.com.au>
8016 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the

8019 2001-11-26 Akim Demaille <akim@epita.fr>
8021 * bin/autoscan.in (%c_keywords): Build it at top level.
8022 Map to 1 in order to simplify its uses.

8026 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8027 Remove $filepath, useless.
8028 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8029 variables, they are really part of the tokens.
8030 Split the input line on spaces and then look for tokens.
8031 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8032 because of `lex$U.$(OBJEXT)'.
8033 (&scan_files): Use "@list" instead of join.
8034 * doc/Makefile.am (CLEANFILES): Add *.fns.
8036 2001-11-26 Akim Demaille <akim@epita.fr>
8038 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8039 Remove, replaced by...
8040 * tests/wrappl.in: Be common for all the Perl executables.
8041 In particular autoscan and autoheader want -I.
8042 * configure.ac: Adjust.
8043 * lib/autoscan/headers: errno.h is portable.
8045 2001-11-26 Akim Demaille <akim@epita.fr>
8047 * bin/autoscan.in (used): New.
8050 2001-11-26 Akim Demaille <akim@epita.fr>
8052 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8054 (&scan_sh_file): Remove a duplicate pattern.
8055 (&check_configure_ac): Use long options.
8056 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8058 2001-11-26 Akim Demaille <akim@epita.fr>
8060 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8061 Before, having a line containing the opening of a multi line
8062 comment made the whole line be ignored.
8064 2001-11-26 Akim Demaille <akim@epita.fr>
8066 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8067 (testsuite Scripts): Be one of its subsection.
8068 (Autotest Logs): New.
8070 2001-11-26 Akim Demaille <akim@epita.fr>
8072 Test groups are now run two directories deeper.
8074 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8075 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8077 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8078 top_srcdir, builddir and top_builddir.
8079 Use `at_*dir' relatively to the directory containing the
8080 suite, use `*dir' when relatively to the current group dir.
8082 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8084 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,

8086 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8089 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8091 * doc/autoconf.texi (Using System Type): Add an example of `case
8092 $host' usage so people quit using `case $target' everywhere.
8094 2001-11-22 Akim Demaille <akim@epita.fr>
8096 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8097 spotted by Jim Meyering.
8099 2001-11-16 Paul Eggert <eggert@twinsun.com>
8101 This patch implements a `long double' suggestion by Oliver Kiddle.
8103 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8104 static, to catch errors if the value isn't known at compile-time
8105 and the compiler supports dynamic arrays. Change its name from
8106 `_array_' to `test_array' to avoid potential name clashes.
8107 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8108 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8109 better than double. Catch a bug in GCC 2.95.2 x86.
8110 * doc/autoconf.texi (C Compiler): Document the above.
8113 2001-11-13 Akim Demaille <akim@epita.fr>
8115 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8117 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8119 2001-11-13 Akim Demaille <akim@epita.fr>
8121 * lib/autotest/general.m4 (AT_INIT): After having run the test
8122 group, go back to the initial directory, not to at_suite_dir.
8124 2001-11-13 Akim Demaille <akim@epita.fr>
8126 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8127 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8128 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8130 (AT_CHECK_CONFIGURE): Use absolute paths.
8131 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8132 The problem is still the old one: there is no means in M4 (that I
8133 know about) to create a defining macro, because there is no means
8134 to create `$1' etc., therefore, the defining macro ``swallows''
8135 all the arguments meant to the defined macro.
8137 2001-11-13 Akim Demaille <akim@epita.fr>
8139 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8140 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8142 * tests/aclocal.m4: Remove, as it is no longer used.
8144 2001-11-13 Akim Demaille <akim@epita.fr>
8146 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8147 variable names when referring to a single test group, or to
8148 `suite' when referring to the whole test suite.
8149 `at_last_test' is removed: m4 compute at_format itself.
8150 (at_stdout, at_stder1, at_stderr): New variables.
8151 (AT_CHECK): Use them.
8153 2001-11-13 Akim Demaille <akim@epita.fr>
8155 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8157 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8158 Do it as soon as a test fails, don't wait till the end of the test
8160 Don't remove $as_me.[0-9]*, since these files no longer exist.
8162 2001-11-13 Akim Demaille <akim@epita.fr>
8164 * tests/tools.at: Use absolute paths, since we are no longer run
8167 2001-11-13 Akim Demaille <akim@epita.fr>
8169 Now that tests are running in their own private dir, there is no
8170 need to list the files to remove at the end of tests groups.
8172 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8173 (AT_data_files, at_data_files): Remove.
8174 (AT_CLEANUP, AT_DATA): Simplify.
8176 Remove the group dir if !debug && !failed.
8177 * tests/atspecific.m4: Adjust.
8179 2001-11-13 Akim Demaille <akim@epita.fr>
8181 Start a new layout for Autotest: `testsuite' creates
8182 `testsuite.dir' in which the at-check-line etc. files are to be
8183 found, and `testsuite.dir/003' where the test group 3 is run.
8185 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8186 at_check_line_file, at_format, at_test_normalized, at_group_dir
8188 Create the directories.
8189 Use absolute paths for at- files.
8192 2001-11-11 Michael Matz <matz@kde.org>
8194 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8196 (m4_car): Properly quote arguments.
8198 2001-11-13 Akim Demaille <akim@epita.fr>
8200 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8201 with stricter rules on LIBOBJS.
8203 2001-11-12 Paul Eggert <eggert@twinsun.com>
8205 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8206 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8209 2001-11-12 Akim Demaille <akim@epita.fr>
8211 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8213 2001-11-12 Akim Demaille <akim@epita.fr>
8215 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8216 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8217 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8218 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8219 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8220 specify to what the macro should be defined (typically to 1).
8222 2001-11-12 Akim Demaille <akim@epita.fr>
8224 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8227 2001-11-12 Akim Demaille <akim@epita.fr>
8229 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8230 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8231 definition used by Automake where LEX is +/- "${missing} lex" and
8232 `missing' itself contains variables.
8234 2001-11-12 Akim Demaille <akim@epita.fr>
8236 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8237 Now that M4sh pushes BODY, the comments were output at the end of
8240 2001-11-08 Akim Demaille <akim@epita.fr>
8242 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8243 that we can trace macros from aclocal.m4.
8244 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8245 obsoleted, and redirect to the former anyway.
8246 Reported by Ralf Corsepius.
8248 2001-11-08 Akim Demaille <akim@epita.fr>
8250 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8251 processed only if present.
8252 * tests/torture.at (Configuring subdirectories): Use autoreconf
8253 instead of successive calls to autoconf.
8254 Add a nonexistent subdirectory to exercise the patch above.
8255 Reported by Ralf Corsepius.
8257 2001-11-08 Kevin Ryde <user42@zip.com.au>
8259 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8260 doesn't accept .S files.
8262 2001-11-07 Akim Demaille <akim@epita.fr>
8264 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8265 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8266 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8267 * bin/autom4te.in (warn_forbidden): New.
8268 (handle_output): Use it.
8269 Read m4_pattern_forbid with messages.
8271 2001-11-05 Akim Demaille <akim@epita.fr>

8314 Add basename, dirname, and fileparse.
8316 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8317 Don't look for aclocal flags if we already know aclocal is not
8319 Move aclocal.m4t only if it exists.
8320 Reported by Ezra Peisach.
8322 2001-11-03 Akim Demaille <akim@epita.fr>
8324 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8325 passed on command line, defaulting to ./configure.ac if present.
8326 (&maybe_autoreconf, File::Find): Remove, unused.
8327 (&autoreconf): If autoconf is not used, don't try to trace.
8329 2001-11-02 Akim Demaille <akim@epita.fr>
8331 * configure.ac: Bump to 2.52g.
8333 2001-11-02 Akim Demaille <akim@epita.fr>
8337 2001-11-02 Akim Demaille <akim@epita.fr>

8348 Don't run libtoolize and gettextize if --install is not given.
8350 2001-11-01 Paul Eggert <eggert@twinsun.com>
8352 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8353 be invoked before _AS_LINENO_PREPARE.
8354 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8355 than character ranges.
8357 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8358 invoking AS_BASENAME. Set the locale variables to 'C' if
8359 possible, as POSIX requires this to get the traditional
8361 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8363 2001-10-31 Paul Eggert <eggert@twinsun.com>
8365 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8366 with {}, as that triggers a bug in Bash 2.05.
8368 (_AS_LINENO_PREPARE): Use Sed rather than
8369 Awk. Fix the sed prepass to work even if there are multiple
8370 instances of $LINENO on the same line. Do not substitute for
8371 other variables like $LINENOT. Do not check file dates; such a
8372 check is unreliable on sufficiently fast machines, and removing
8373 the check makes the code simpler and more reliable. Check for
8374 output and chmod failures.
8376 * doc/autoconf.texi (Special Shell Variables): Document
8379 2001-10-31 Akim Demaille <akim@epita.fr>

8389 * configure.ac: Adjust.
8391 2001-10-26 Paul Eggert <eggert@twinsun.com>
8393 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8394 lib/Autom4te/Struct.pm:
8395 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8398 * doc/autoconf.texi (Special Shell Variables): Document some
8399 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8401 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8402 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8403 eval $LINENO is not portable in practice.
8405 2001-10-24 Akim Demaille <akim@epita.fr>
8407 * lib/Autom4te/General.pm (backname): New.

8419 2001-10-22 Paul Eggert <eggert@twinsun.com>
8421 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8422 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8423 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8424 POSIX decided to standardize on the int flavor of strerror_r.
8425 Always do char* test, as there's no reason not to.
8426 Assign to a char* var, to catch strerror_r that returns int*.
8428 * doc/autoconf.texi (Particular Functions):
8429 Document the above changes. Also, document the fact that
8430 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8432 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8434 2001-10-20 Akim Demaille <akim@epita.fr>
8436 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

8448 Be sure to honor --force with gettextize.
8450 * doc/autoconf.texi: Adjust.
8452 2001-10-20 Akim Demaille <akim@epita.fr>
8454 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8456 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8457 `intl' is already present, as it refuses unless --force.
8458 (&parse_args): Use -I, --include instead of the old Autoconf
8460 ($localdir, $autoconf_dir): Remove.
8462 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8464 2001-10-19 Jens Petersen <petersen@redhat.com>
8466 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

8471 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated

8473 Don't mention `automatically' in addition to `generated'.

8485 configure.ac being studied.
8487 2001-10-18 Paul Eggert <eggert@twinsun.com>

8490 long, to work around a bug in the HP C compiler version HP92453-01
8493 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8494 (AS_BASENAME_EXPR): New macro.
8495 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8496 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8497 and fall back on 'sed' only if the other two fail. This makes
8498 AS_BASENAME act more like AS_DIRNAME.
8499 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8500 contains white space.
8501 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8502 Use AS_DIRNAME, since I think it's now DOS-friendly.
8503 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

8553 (Syntax of the shell scripts): Don't.
8554 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
8555 bother with $force since...
8556 * lib/Autom4te/General.pm: does.
8558 2001-10-08 Akim Demaille <akim@epita.fr>
8560 * bin/autoreconf.in: Rewrite in Perl.
8561 * configure.ac: Adjust.

8632 * lib/autotest/general.m4 (AT_INIT): Likewise.
8633 * tests/base.at: Adjust the tests to use AS_INIT.
8634 * tests/tools.at (AT_DATA_FORBIDDEN): New.

8644 shell does not support LINENO, and if CONFIG_SHELL is unset or
8645 empty, and if we can find a shell that does support LINENO,

8651 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8652 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8653 build of $(TESTSUITE).
8655 2001-10-05 Akim Demaille <akim@epita.fr>
8657 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path
8658 iff we are a bareword.
8659 Reported by Raja R Harinath.
8661 2001-10-05 Akim Demaille <akim@epita.fr>

8723 Don't use nested parenthesization. This patch was originally
8724 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
8725 but somehow it didn't get incorporated then.

8736 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

8968 Do not pass a first argument with leading '-'
8969 to expr, by parenthesizing initial integers that might be negative.

8975 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8976 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8977 whether it is a (compile-time) error to pass an argument to

8995 Add test for AS_BASENAME.
8996 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8997 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8998 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8999 * tests/base.at: Fixed the expected responses. The old ones were
9001 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9002 the documentation claims it should (and how it behaved in 2.13).

9006 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9007 the AC_CONFIG_COMMANDS invocation.
9008 This also solves the name clash problems.

9011 No longer to be shipped.
9012 (version.in): Remove.

9017 the only optional argument is the name of the test suite.
9018 Expect `package.m4' to define the package signature.
9019 * lib/autom4te.in (Autotest): Add `package.m4?'.
9020 * tests/Makefile.am (package.m4): New.

9046 2001-09-17 Paul Eggert <eggert@twinsun.com>
9048 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9049 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9050 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9051 when they don't exist.
9053 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9054 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

9058 version with the version used by fileutils 4.1, except use

9104 * lib/autotest/general.m4 (AT_INIT): Create and remove
9105 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9106 test suites can cohabit.
9108 2001-09-13 Akim Demaille <akim@epita.fr>
9110 * tests/mktests.sh: Don't output banners for empty test files.

9219 the maintainer is dumb enough to do that...
9221 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9222 excellence in M4 quotation: consider `__file__' is active.

9272 2001-08-31 Akim Demaille <akim@epita.fr>
9274 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9275 serious problems handling heredocs in heredocs.
9276 Reported by Nicolas Joly.
9278 2001-08-31 Akim Demaille <akim@epita.fr>
9280 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9281 (Making testsuite Scripts): Update.
9283 2001-08-31 Akim Demaille <akim@epita.fr>
9285 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9287 2001-08-31 Akim Demaille <akim@epita.fr>
9289 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9290 (testsuite Scripts): There is no such thing as `atconfig.in'.
9291 And actually one diagram is missing: test suite runtime.
9293 2001-08-31 Akim Demaille <akim@epita.fr>
9295 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9298 2001-08-31 Akim Demaille <akim@epita.fr>
9300 * bin/autoupdate.in (@include): `installcheck' revealed the path
9301 to m4sugar was lacking!
9303 2001-08-31 Akim Demaille <akim@epita.fr>
9305 * man/Makefile.am (.x.1): We really have to pass
9306 autom4te_perllibdir.

9310 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

9317 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9318 Use directly autom4te, not autoconf.

9321 2001-08-31 Akim Demaille <akim@epita.fr>
9323 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9324 * bin/autoheader.in (%symbol): Strip arguments of macros.
9326 2001-08-31 Akim Demaille <akim@epita.fr>

9341 * bin/autom4te.in ($autoconf): Pass --force.
9342 `print $out' doesn't print `$_' but `$out'.
9343 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9344 (autoheader): Pass --force since the test suite goes too fast for
9346 Adjust to the new autoheader messages.
9348 2001-08-31 Akim Demaille <akim@epita.fr>
9350 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9351 Check the completeness of the #template.
9352 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9353 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9356 2001-08-31 Akim Demaille <akim@epita.fr>
9358 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9359 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9360 Drop AC_MACRODIR dead for real.
9361 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9362 `autoheader: `config.hin' is created'.
9363 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9365 2001-08-31 Akim Demaille <akim@epita.fr>
9367 * bin/autoheader.in: Rewrite in Perl.

9372 * bin/autoconf.in (--include, -I): New option.
9373 Map --localdir, --autoconf-dir onto it.
9374 Forward autom4te's options instead of interpreting them.
9375 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9376 There is no such envvar since the inception of autom4te.cfg.
9377 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9378 * bin/autoupdate.in: Adjust, and perform more control.
9379 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9380 * tests/autoconf: Dittowise.
9382 2001-08-31 Akim Demaille <akim@epita.fr>

9394 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9395 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9396 installed peer executables, only PATH is allowed to resolve it.
9397 Pass `autoconf_dir' via options, not via invisible envvars.
9398 * lib/Autom4te/General.pm (&find_peer): Remove.
9399 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9400 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9401 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9402 find the executables for it.
9403 * tests/Makefile.am: Major cleanup. Too lazy to document...
9404 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9406 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9407 indeed related to running the test suite, while passing
9408 --autoconf-dir and others is related to running non installed
9409 Autoconf executables. So don't do that, leave it to...
9410 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9411 * tests/autoscan: New.
9412 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

9428 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9429 Suggested by Paul Eggert.
9431 2001-08-29 Akim Demaille <akim@epita.fr>
9433 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9434 download in a tmp dir.
9436 2001-08-29 Akim Demaille <akim@epita.fr>
9438 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9439 case insensitive OSes out there :(

9458 foo=`(command) 2>/dev/null`

9461 (at-devnull): Rename as...
9463 (--clean): Remove AT-* files too.

9499 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9500 Support `VAR=VAL' as arguments.

9985 magic values from an object file when cross-compiling.
9986 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9988 2001-08-10 Akim Demaille <akim@epita.fr>
9990 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9992 Suggested by Russ Allbery.
9994 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9996 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9997 current $prefix to the sub-configures.
9999 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10001 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10002 extension (needed on BeOS). Reported by Guido van Rossum.
10004 2001-08-09 Akim Demaille <akim@epita.fr>
10006 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10008 2001-08-07 Akim Demaille <akim@epita.fr>
10010 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10012 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10013 No need to remove the files before and after the each test, before
10014 each test and at the end of the suite is enough.
10015 Display only the children `times', not the shell's.
10016 If the test failed or was skipped, at-times is not available.
10018 2001-08-07 Akim Demaille <akim@epita.fr>
10020 Always produce testsuite.log, including when there are no
10021 failures. This helps getting information on skipped tests, and
10022 duration of the tests. Err, implement the latter btw.
10024 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10025 Dump information on the first run of each test.
10026 (AT_CLEANUP): Create `at-times' containing the duration of the
10029 2001-08-07 Akim Demaille <akim@epita.fr>
10031 The use of `dumpstat' revealed that `len' was used although it
10032 should not. m4_text_wrap was using it, but in the Autoconf world
10033 where it is legal. Hence (i) test M4sh in its own world, not
10034 Autoconf's, and (ii), ahem, fix the bug :)
10036 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10037 does not like `' instead of [].
10038 (AT_INIT): Forbid `^_?AT_'.
10039 And don't output such tokens.
10040 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10041 `script.as', and `autom4te.cache'.
10042 Remove `empty' and `macro' which are no longer used.
10043 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10044 * tests/m4sugar.at: Use it.

10064 2001-08-04 Akim Demaille <akim@epita.fr>
10066 Don't rely on M4sugar outputting the patterns in files, since we
10067 might process the output _without_ running m4, hence without these
10070 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10071 * bin/autom4te.in (@Request::includes): Remove, unused.
10072 (@Request::source): Rename as...
10073 (@Request::input): this.

10080 2001-08-04 Akim Demaille <akim@epita.fr>
10082 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10083 autoconf', i.e., in addition to caching traces, cache the output.

10086 (Request::id): this.
10087 ($cache, $icache, $tcache, $ocache): New.

10096 * bin/autom4te.in ($force): New.
10097 (&parse_args, &print_usage): -f, --force is a new option.
10098 (&handle_output): CPP directives might have spaces after `#'.
10099 (&parse_args): The first file only can be frozen.
10101 2001-08-04 Akim Demaille <akim@epita.fr>
10103 Don't let autom4te compute the `include' traces several times:
10104 first check that the trace cache file is up to date, and then
10105 compare its timestamp with that of the output.
10107 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10108 the preamble. Don't require 5.005 as Autom4te::General does it,
10109 and better yet (use `use', not `require'!).
10110 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10111 Class::Struct as Autom4te::Struct.
10112 * lib/Autom4te/General.pm (File::stat): Use it.

10114 * bin/autom4te.in: Use it.
