2 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3 Stepan Kasal <kasal@ucw.cz>
5 * doc/autoconf.texi (Particular Programs): Do not promise that
6 we always prefer the GNU version of the program, and that we
7 search according to PATH; both rules can have exceptions.
8 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9 AC_PROG_SED. Move descriptions of limitations
10 to the Limitations of Usual Tools section.
11 (Limitations of Usual Tools) <sed>: Mention script length
12 limitations with Solaris /usr/ucb/sed.
13 <grep>: Fix wording for empty alternative. Mention that -c and
14 -l should not be combined, and that -E and -F should not be
15 combined.
17 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
18 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
20 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
21 limits in Solaris 8 /usr/ucb/sed by testing a long script.
23 2006-05-22 Stepan Kasal <kasal@ucw.cz>
25 * doc/autoconf.texi (Defining Symbols): Literal parameter of
26 AC_DEFINE is now passed to m4_pattern_allow.
27 * NEWS: Mention that; likewise for AC_SUBST.
28 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
29 the parameter to m4_pattern_allow.
30 * tests/tools.at: Add a check for that.
32 2006-05-22 Stepan Kasal <kasal@ucw.cz>
34 * lib/autoconf/status.m4: Fix typos.
36 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
39 only the files that this macro generates.
41 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
43 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
44 the HP-UX sed limitation of 99 commands, labels do not count.
45 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
46 in the comment.
47 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
49 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
51 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
52 Import the following fix from coreutils:
54 2006-01-13 Jim Meyering <jim@meyering.net>
56 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
57 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
58 not double-quote uses of that variable, to accommodate the rare
59 case in which getmntent is available in none of the libraries
60 checked. This happens at least on FreeBSD 5.0.
62 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
64 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
65 ac_config_guess, ac_config_sub, and ac_configure, since evidently
66 some other programs unwisely rely on these undocumented vars.
67 But put in warning comments about them.
68 Problem reported by Ralf Wildenhues in
69 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
70 * NEWS: Document that these variables are intended to go away.
72 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
74 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
75 and set the language to C++ (analogous to the equivalent Fortran
76 tests).
78 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
79 * doc/autoconf.texi (C++ Compiler): Document it.
80 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
81 * NEWS: Update.
83 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
85 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
86 that caused config.status to generate 100-command sed scripts; the
87 portable limit is 99.
89 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
91 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
92 variable `ac_d' instead of `d' to avoid infringing namespace.
93 Report by Ralf Menzel.
95 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
97 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
98 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
99 * tests/tools.at (autoconf: subdirectories): New test, taken from
100 the corresponding problem report by Ralf Wildenhues in:
101 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
103 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
104 Quote some uses of shell variables if they might suffer unexpected
105 globbing. This doesn't fix all instances of quoting problems that
106 I found, just the easy ones that look safe.
107 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
108 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
109 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
110 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
111 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
112 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
113 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
114 Likewise.
115 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
116 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
118 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
120 * bin/autoreconf.in ($help): Reword according to the manual.
121 Suggested by Olly Betts.
123 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
124 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
126 * bin/autoreconf.in: Pass the directory argument to
127 `require_configure_ac'. Fix comment.
128 * tests/torture.at (Configuring subdirectories): Expose this.
129 Reported by Olly Betts.
131 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
133 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
134 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
135 Automake as follows:
137 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
138 `$configure_in' instead of `configure.in', to preserve
139 directory component.
141 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
143 * config/config.guess, config/config.sub, config/texinfo.tex,
144 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
146 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
148 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
149 test for C99 conformance; (bool) 0.5 is an integer constant
150 expression, but (bool) -0.5 is not. Problem reported by Fedor
151 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
153 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
155 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
156 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
157 Warn about obsolete install-sh files. Remove stray sentence
158 fragment and fix cross reference.
159 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
160 install -d; this undoes the 2006-05-10 change.
161 (MKDIR_P): Mark with AN_MAKEVAR.
162 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
163 that we don't require $INSTALL to be thread-safe. Move comments
164 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
165 of AC_PROG_INSTALL. Output a message saying that we're checking
166 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
167 MKDIR_P instead of AC_SUBST.
168 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
169 Special magic for MKDIR_P, too.
170 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
171 a dnl.
172 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
174 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
176 Sync from Automake, as follows:
178 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
179 * config/install-sh: Initialize IFS, so field splitting isn't
180 turned off later.
181 * config/mkinstalldirs: Likewise.
182 * config/missing: Remove superfluous quotes. Replace all uses of
183 `[' by `test', for consistency, and for..
184 * config/missing (sed_minuso, sed_output): New variables.
185 (autom4te, help2man, makeinfo): Use them. Unifies detection of
186 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
187 Fixes `missing' to detect `--output' for help2man. Fixes
188 PR automake/483. Report by Dennis J. Linse.
189 (autom4te): Document in `missing --help'.
191 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
193 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
194 * config/install-sh: Don't use 'path' to talk about file names,
195 as per GNU coding standards. Close a race condition reported by Ralf
196 Wildenhues and Stepan Kasal. There is still a race condition
197 on hosts that predate Posix 1003.1-1992, but we can't help this.
198 Don't mishandle weird characters like space on pre-Posix hosts.
199 Invoke mkdir at most once per dir arg on pre-Posix hosts.
200 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
201 AC_PROG_MKDIR_P from AS_MKDIR_P.
202 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
203 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
204 earlier editions are not (including Automake 1.8.3).
205 Do not suggest mkinstalldirs for thread-safety.
206 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
207 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
208 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
209 presence of special characters and race conditions.
210 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
211 in Autoconf's name space.
213 2006-05-10 Bruno Haible <bruno@clisp.org>
214 and Paul Eggert <eggert@cs.ucla.edu>
216 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
217 from Automake with minor changes.
218 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
220 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
222 * config/install-sh: Update to Automake CVS version, as follows:
223 2006-04-25 Stepan Kasal <kasal@ucw.cz>
224 * lib/install-sh: Simplify the expr implementation of dirname.
225 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
226 * lib/install-sh: Handle --, and diagnose unknown options.
228 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
230 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
231 `./autom4te' to create `./testsuite', since the `all' target
232 will ensure its presence, but `installcheck' should not create
233 the uninstalled wrappers.
235 * tests/torture.at (Unusual Automake input files): Skip if we
236 detect automake < 1.8.
238 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
240 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
241 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
242 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
243 * NEWS: Update.
245 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
248 munge (multiple) white space and other oddities.
249 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
250 single quotes in variable assignment.
251 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
252 and similar failures by adding multiple spaces, tabs, and other
253 special characters.
254 Report and different test suggested by Francesco Romani
255 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
257 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
258 single quotes, we only need to search for single quotes; this
259 both simplifies the search pattern, and makes us less
260 susceptible to `echo' variations for arguments not containing
261 single quotes.
262 (_AC_ARG_VAR_VALIDATE): Likewise.
264 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
266 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
267 `$*' and IFS concatenation issue with traditional shells and
268 bash-2.04. Report by Seanster@Seanster.com.
270 2006-05-03 Bruno Haible <bruno@clisp.org>
272 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
273 precisely which Mac OS X versions have the od problem.
275 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
277 * doc/autoconf.texi: Use @option systematically.
278 (Integer Overflow):
280 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
281 and Bruno Haible <bruno@clisp.org>
283 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
284 about 'od'.
285 (Integer Overflow): Mention the special case of integer division
286 overflow.
288 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
290 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
291 traditional shells like the Solaris one that do not use the
292 first IFS character for assembling `$*'.
293 Prompted by a related report from autoconf_bug@nro.ca.
295 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
296 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
298 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
299 Mention more problems with the -e option.
301 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
303 * NEWS: Typo.
304 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
306 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
307 in URLs to improve DVI formatted output (requires texinfo 4.6).
308 (System Services, Systemology, Shellology): Likewise.
309 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
310 output.
312 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
313 continuous text.
314 (Runtime): Fix macro argument names to match description:
315 `action-if-found' -> `action-if-true' and similarly.
316 (Obsolete Macros): Likewise.
317 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
318 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
319 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
321 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
323 * doc/autoconf.texi (Limitations of Make): Clean up markup.
325 * ChangeLog: Typo.
326 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
327 DVI output.
329 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
331 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
332 /bin/sh set unsorted output.
333 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
334 * tests/local.at: Likewise.
336 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>

339 (Integer Overflow, Null Pointers, Buffer Overruns):
340 (Floating Point Portability, Exiting Portably): New sections.
341 (Writing Test Programs): Fix some langauge. Recommend exiting
342 with status 1, not merely nonzero. Clarify exit declaration.
343 (Run Time): Move C exit status stuff to new Exiting Portably section.
344 (Systemology): Mention Posix and levenez. Update v7 reference.
345 (Portable Shell): Mention the Posix shell.
347 2006-04-25 Stepan Kasal <kasal@ucw.cz>
349 * bin/autoconf.as (me): Replace by as_me.
351 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
353 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
354 since as_me isn't set yet.
356 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
358 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
359 a few minor bugs in this area.
361 * doc/autoconf.texi (Programming in M4sh): Comment out the
362 documentation of AS_BASENAME, for now.
363 (Shell Substitutions): Do not use AS_DIRNAME in an example.
364 (Limitations of Builtins) <basename>: Do not refer to
365 AS_BASENAME.
366 * bin/autoconf.as (me): Don't use AS_BASENAME.
367 (dir): Remove the unused variable.
368 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
369 AS_DETECT_REQUIRED. All uses changed.
370 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
371 All uses changed.
372 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
373 (AS_BASENAME): Use "basename --" to protect against leading "-".
374 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
375 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
376 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
377 (_AS_DIRNAME_PREPARE): Likewise.
378 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
379 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
380 (AS_DIRNAME): Use "dirname --".
382 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
384 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
385 of "run time" and "run-time" changed to "runtime", for consistency.
386 * lib/autoconf/fortran.m4: Likewise (in comment).
387 * lib/autoconf/functions.m4: Likewise.
388 * lib/autoconf/general.m4: Likewise.
389 * lib/autoconf/headers.m4: Likewise.
391 * doc/autoconf.texi (Run Time): Document the exit status situation
392 with more accuracy and detail.
394 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
396 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
397 Archive is not officially `GNU' any more. Update URL.
398 (Defining Directories): Likewise
399 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
401 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
403 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
404 newline from the `trap' code to finish `config.log'; the NetBSD
405 /bin/sh resets the exit status after an empty command, as
406 documented in doc/autoconf.texi.
407 Reported by Dalibor Topic <robilad@kaffe.org>.
409 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
411 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
412 Suggested by Bruno Haible.
414 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
416 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
417 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
418 Instead, just list the shells that we know work.
419 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
420 changed. Be more cautious about the _cv_ variable.
421 * tests/tools.at (Syntax of the shell scripts): Check the
422 _cv_ variable once, at first, to avoid an internal autoconf error
423 when sh -n does not work.
425 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
427 * lib/Autom4te/FileUtils.pm: Sync from Automake.
429 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
431 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
432 use ">&-" since we're only 99.999% sure that this is portable,
433 and since the MinGW bug is fixed in a different way.
434 * lib/autotest/general.m4 (AT_INIT): Likewise.
436 2006-04-16 Stepan Kasal <kasal@ucw.cz>
438 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
439 before opening config.log, to avoid hitting a bug on MinGW.
441 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
443 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
444 AS_MESSAGE_LOG_FD before reopening it onto the log file.
445 This works around a MinGW bug reported by Eric Paire.
446 Make sure that all writes to the log file append to it,
447 rather than possibly losing data.
448 * lib/autotest/general.m4 (AT_INIT): Likewise.
450 2006-04-14 Stepan Kasal <kasal@ucw.cz>
452 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
453 description.
455 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
457 * NEWS: Update.
459 * configure.ac (AC_INIT): Bump to 2.59d.
461 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
463 Version 2.59c.
465 * Makefile.maint (news-date-check): Do not require a leading `*'
466 before the release date in NEWS.
468 2006-04-12 Stepan Kasal <kasal@ucw.cz>
469 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
471 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
472 the instantiated file do not contain the string 'datarootdir'
473 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
474 @mandir@, replace the reference '${datarootdir}' by the value.
475 * tests/torture.at (datarootdir workaround): New test.
476 * NEWS: Advertise this temporary fixup.
477 Based on a patch by Bruno Haible, reported and analyzed by
478 Paul Eggert and Noah Misch.
480 2006-04-12 Eric Blake <ebb9@byu.net>
482 * tests/autotest.at (Debugging a failed test): Fix comment.
484 2006-04-12 Stepan Kasal <kasal@ucw.cz>
486 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
487 all the changes since 2006-04-07.
489 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
491 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
492 succeeded, but `ln -s file dir' failed, take care to remove the
493 leftover target before the next test, to prevent its spurious
494 failure; also make sure `ln file dir' works before selecting it.
495 Thanks to Keith Marshall for pointing this out.
496 * THANKS: Update.
498 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
499 assignments in `at_debug_args', so that we put them correctly
500 in the `run' script.
501 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
502 Reported by Eric Blake.
504 2006-04-11 Eric Blake <ebb9@byu.net>
506 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
507 top-level tests after micro-suite has been run. Used in...
508 (Debugging a successful test, Debugging script and environment),
509 (Debugging a failed test): ...these new tests. The first of these
510 is fixed by...
511 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
512 macro, split out from...
513 (AT_INIT): ...here, so that using -d also generates a run script.
514 Document that -d inhibits top-level logging.
515 * doc/autoconf.texi (testsuite Invocation): Document that -d only
516 inhibits top-level logging; debug scripts are created.
518 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
519 check.
520 * tests/autotest.at (Empty test, Empty check): New test to check it.
522 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
523 from gcc.
525 2006-04-10 Stepan Kasal <kasal@ucw.cz>
527 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
528 the files if a problem appears. Make the empty *.at files
529 read-only, too. Proposed by Ralf Wildenhues.
531 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
533 * config/Makefile.am: Add comment to force updated Makefile.in.
535 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
536 space only patch to this file, this patch causes the Makefile.in
537 files that include freeze.mk to be updated, and thus have a
538 newer time stamp again, which in turn makes a pristine CVS
539 checkout have correct time stamps.
541 * Makefile.maint (cvs-sv): New macro, to be used..
542 (config.guess-url_prefix, config.sub-url_prefix)
543 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
544 point to CVS text checkout of Gnulib files.
545 (copyright-check): Bump current year.
546 (announcement): Do not hard-wire `./announce-gen'.
547 (cvs-update): Propagate failures of `cvs' and `move-if-change'
548 correctly.
549 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
550 `chmod +x'.
551 (wget_files): Update config.guess, config.sub, texinfo.tex by
552 `wget-update', now that their URLs work again.
554 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
556 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
557 Problem noted by Paul D. Smith.
559 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
561 * doc/autoconf.texi: Remove unused words from word list.
562 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
563 .x-sc_trailing_space: New files.
565 * doc/standards.texi: Sync from gnulib.
567 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
568 `LIBOBJDIR' as experimental.
570 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
571 with a target directory; it's internally implemented as `cp'
572 anyway, but since Autoconf advertises the possibility to use
573 a target directory when LN_S is `ln -s', we need to find out.
574 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
575 analyzed by Keith Marshall <keith.marshall@total.com>.
577 * THANKS: Update.
579 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
581 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
582 confdefs.h as-is. In general, if it has backslash-newline or the
583 like, then it doesn't work either to sort or to remove empty
584 lines.
586 2006-04-09 Stepan Kasal <kasal@ucw.cz>
588 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
590 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
592 * lib/autom4te.in (Automake-preselections): Preselect
593 _AM_SUBST_NOTMAKE.
595 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
597 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
598 apostrophe within a single-quoted string, as this is the usual
599 tradition and is easier to read than '"'"'. Don't rely on the
600 shell treating "$/" like '$/'. Use a more-consistent indenting
601 style for the trap.
603 2006-04-09 Eric Blake <ebb9@byu.net>
605 * tests/autotest.at (Backquote command substitution),
606 (Multiline backquote command substitution): Remove mistaken
607 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
608 applied...
609 (Parenthetical command substitution, Multiline parenthetical
610 command substitution): here.
612 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

630 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
631 Gnulib section.
632 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
633 suggest a #define rather than a typedef for _Bool, and mention
634 Gnulib rather than trying to substitute stdbool code.
635 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
636 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
637 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

640 headers too.
641 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
642 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
643 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
644 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
645 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
646 (C Compiler): Move AC_C_LONG_DOUBLE to ...
647 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
648 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
649 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
650 (Coding Style). Don't mention m4_expand_once.

669 New macros.
671 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
672 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
674 2006-04-08 Stepan Kasal <kasal@ucw.cz>
676 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
677 of the warning introduced by the 2001-08-28 change.
679 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
680 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
682 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
683 variables shall be overriden by the cache.
684 * tests/torture.at (AC_ARG_VAR): Test also with a first value
685 that contains braces.
687 2006-04-07 Stepan Kasal <kasal@ucw.cz>
689 Revert the patch from 2006-04-01 and only improve
690 _AS_DETECT_BETTER_SHELL:
692 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
693 skip nonexistent directories.
694 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
695 only shell candidates which exist.
696 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
697 * lib/autotest/general.m4 (AT_INIT): No need to give three
698 parameters to _AS_PATH_WALK.
700 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
701 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
703 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
704 distinguish m4sugar macros.
705 * tests/tools.at (autoupdating with aclocal and m4_include):
706 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
707 test case by Noah Misch <noah@cs.caltech.edu>.
709 2006-04-07 Stepan Kasal <kasal@ucw.cz>
711 Revert my change from 2006-03-17, in other words:
712 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
713 and DUALCASE=1.
714 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
715 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
716 it is set.
718 2006-04-07 Eric Blake <ebb9@byu.net>
720 * doc/autoconf.texi (Programming in M4sh): Document that
721 AS_MKDIR_P exits the script on failure.
722 * lib/autotest/general.m4: Remove redundant AS_ERROR.
724 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 * config/elisp-comp, config/install-sh, config/mdate-sh,
727 config/missing, config/mkinstalldirs: Sync from Automake.
729 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
730 from Automake.

741 Eric Blake <ebb9@byu.net>,
742 Paul Eggert <eggert@cs.ucla.edu>,
743 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
745 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
746 whether `set' quotes correctly: redirect stderr of the tested
747 `set', and use a subshell, for Ultrix; use `sed' instead of
748 `grep' for zsh `set' which may write binary output; match only
749 at the beginning of a line, to avoid false positives.
750 In order to avoid false positives by unrelated variables with
751 multiline content, put the dump algorithm in a subshell and
752 unset all variables containing newlines (except some which are
753 special to the shell). Warn about cache variables that are
754 unset.
756 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
758 * config/config.guess, config/config.sub, config/texinfo.tex:
759 Sync from upstream.

767 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
768 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
769 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
770 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
772 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
773 shell issue with double-quoted command substitutions of native

782 (sc_cast_of_alloca_return_value, sc_error_exit_success)
783 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
784 (m4-check): Likewise.

796 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
798 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
799 ac_config_<foo>s again, sometimes normalized, sometimes not.
800 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
801 (AC_CONFIG_COMMANDS): Do not do so here.
802 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
803 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
804 2005-07-25 rewrite. Noticed by Noah Misch.
806 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
807 _AC_PRESERVE_HELP_ORDER, ...
808 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
810 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
811 inside m4_expand_once; it is redundant.
813 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
814 for --help from Cygnus `configure.'
816 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
818 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
819 on a patch proposed by Ralf Wildenhues.
821 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
823 * lib/autoconf/status.m4: Replace <space>''<tab> with

826 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
827 Noah Misch <noah@cs.caltech.edu>
829 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
830 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
831 * doc/autoconf.texi (Help Formatting): New node.
832 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
834 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
836 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
837 lib/autoconf/specific.m4, lib/autoconf/status.m4,
838 lib/autoconf/types.m4, lib/autotest/general.m4,
839 tests/mktests.sh, tests/torture.at: White space cleanup:
840 remove some SPACE before TAB, or add quoting ('' or @&t@).
842 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
844 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
846 2006-04-05 Eric Blake <ebb9@byu.net>
848 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
849 empty test suite works.
850 * tests/autotest.at (Empty test suite): Remove xfail.

858 normalizing it, consistent it with previous releases.
859 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
861 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
863 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
864 Use simplified args that Eric Blake originally suggested.
866 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
868 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
869 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
870 Use 'comm' rather than N instances of grep; this also fixes a bug
871 whereby substrings were incorrectly matched, causing us to not
872 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
873 (exclude_list): Exclude empty macros.
874 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
876 Use awk rather than grep -E or egrep, to avoid
877 portability problems with regular expressions containing newlines.
878 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
879 Switch from grep to awk syntax.
880 (ac_exclude_script): Renamed from ac_exclude_egrep.

886 a subdirectory subject to Cygnus `configure'.
887 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
889 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
890 report request when we have no AC_PACKAGE_BUGREPORT.
892 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
894 * THANKS: Update.
896 * tests/mktests.sh: Update copyright year in the header of the
897 generated files.
899 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
900 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
901 typedef'ed restricted pointer, to catch a compiler bug on
902 HP-UX 11.x, and fix warnings so it passes with -Werror.
903 (_AC_PROG_CC_C99): Likewise.
904 Reported by Albert Chin <china@thewrittenword.com>.

911 (output): Emit AC_CONFIG_SUBDIRS as needed.
912 * tests/autoscan.at (autoscan): Remove XFAIL.
914 2006-04-03 Noah Misch <noah@cs.caltech.edu>
916 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
918 2006-04-03 Eric Blake <ebb9@byu.net>
920 * THANKS: Add myself.
922 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
924 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
925 to log, point to testsuite output tree.
927 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
929 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
930 * doc/autoconf.texi (Function Portability): Mention that C++
931 has trouble with 'exit'.
932 (Guidelines): Test programs shouldn't use 'exit'.
933 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):

961 initial `rm' of the candidate files...
962 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
963 the same list in subsequent `rm' calls, and for the temporary
964 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
965 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
966 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
967 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

1047 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1048 switch all of them on and of when necessary. Fixes the bug when
1049 m4sugar macros (e.g., m4_define) were expanded after the first
1050 automatic update (e.g., after AC_PREREQ or AC_INIT).

1307 newline for portability.
1308 * tests/torture.at (Torturing config.status): Also test 100

1748 by the function rather than ignoring it.
1749 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1750 comparing its address. Intel's interprocedural optimization was

1769 Stepan Kasal <kasal@ucw.cz>
1771 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1772 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1773 make its content writable before removing it. Remove an errorneous
1774 comment from the end, where the logs of the failed tests are copied
1775 to the main log file.
1777 2005-09-27 Stepan Kasal <kasal@ucw.cz>

1784 problems if the testsuite were running too fast.
1786 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1788 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

1800 suggested by Ben Elliston. Handle weird characters correctly.
1802 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1804 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1805 calls, so that the final expansion of this macro is shorter.
1806 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1807 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1808 the cleanup there. Use AS_VAR_* macros, to be more general.
1809 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1811 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1813 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

1833 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1834 in the example. Reported by Bruno Haible.
1835 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1836 "if $undefined_var;" succeeds with my shell.
1838 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1839 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

1860 Update limitations about when to call AC_CONFIG_HEADERS.
1861 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1862 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1863 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1864 ``Configuration Actions''; fix their index entries.
1866 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1867 options correctly. Process N-M as M-N if M is smaller than N.
1868 Process ranges correctly so that N-N will run only N.
1869 Sort and uniquify the tests that will be run. If there is more
1870 than one test, reinsert the banners for the tests.

1876 before passing the macro name to AH_TEMPLATE.
1878 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1879 now opens log after option processing; in particular, --version
1880 and --help do not touch config.log.

1901 When building in place, set srcdir="."; suggested by Tim Van Holder.
1903 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1904 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1905 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1906 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

1923 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1925 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

1941 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1943 Rewrite substantial part of lib/autoconf/status.m4.
1944 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1945 and CONFIG_COMMANDS are not processed in four separate loops.
1946 Instead, there is one main loop. This alows that the common code
1947 is expanded only once, thus config.status (and configure) is smaller.
1949 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1950 the AC_LIST_FILES and cousins macros are no longer used.
1952 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1953 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1954 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1955 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1956 contain the initialization, nor the for loop, nor the associated
1957 commands; all these go to ...
1958 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1959 _AC_OUTPUT_CONFIG_STATUS.
1960 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1961 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1962 (_AC_OUTPUT_FILE): The creation of the sed script ...
1963 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1964 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1965 _AC_OUTPUT_MAIN_LOOP.
1966 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1967 _AC_CONFIG_COMMANDS): Use ...
1968 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1969 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1970 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1971 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1972 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1973 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1974 ... new macros.
1975 (_AC_CONFIG_UNIQUE): Update.
1976 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1977 Replaced by this ...
1978 (_AC_LIST_TAGS): ... new common macro.
1979 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1980 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1981 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1982 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1983 this didn't belong to the `config commands' section.
1984 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1985 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1986 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1987 to the `config commands' section either.
1988 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1989 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1991 ... and many changes to the comments nearby.
1993 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1994 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1995 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1996 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1997 (#define header templates): The comment at the top of the generated
1998 header now includes the name(s) of the source file(s).
2000 Several unrelated small changes:
2002 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2003 parameter to AC_DIAGNOSE.
2004 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2005 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2006 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2007 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2008 with AU::AC_OUTPUT.
2009 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2010 in AC_OUTPUT doesn't double-quote it either.
2011 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2012 parameters.
2014 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2016 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2017 versions of Portland Group compiler produce single- and double-quoted
2018 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2019 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2021 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2023 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2024 This is a corrected version of yesterday's patch.
2026 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2028 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

2032 ac_cv_build_alias to ac_build_alias.
2033 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2035 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2036 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2037 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2038 (AC_ARG_VAR): ... here.
2039 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2040 target_alias.
2042 Keep a list of all precious variables and process them with one simple
2043 for loop, instead of expanding all commands, or, OTOH, complicated
2044 processing of output of "set".
2045 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2046 variable names in new macro...
2047 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2048 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2049 a loop to assign all ac_env_* and ac_cv_env_* variables.
2050 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2051 to INIT_PREPARE.
2052 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2053 its value to shell variable ac_precious_vars and call
2054 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2055 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2056 _AC_ARG_VAR_VALIDATE.
2058 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2059 and the AC_SUBSTs ...

2062 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2063 the ac_subst_files section in config.log.

2074 Fix problems reported by Nicolas Joly.
2075 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2076 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2077 They are generated by the Tru64 v5.1B shell.

2081 Fix my changes from 2005-07-01; reported by Noah Misch.
2082 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2083 description, the macro now accepts only a single tag.

2086 Fix cases when the varsions of Autoconf and Autotest don't match.
2087 Reported by Noah Misch.
2088 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2089 at_top_builddir, for compatibility with older autotest.
2090 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2091 is not set, use at_top_builddir, for compatibility with older
2092 versions of autoconf.
2094 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2096 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2097 Problem reported by Patrick Welche.
2099 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2101 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2102 sed substitution command, so that we allow | in program prefixes
2103 and program suffixes. (& is a problem anyway; we're not fixing
2104 that here.)
2105 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2106 configure_input, top_builddir, srcdir, etc.
2107 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2108 PATH_SEPARATOR in AUTOTEST_PATH.
2110 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2112 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

2118 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2119 directories with weird names. Apparently some people like living

2140 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2141 document to output the default config_* lists to config.status.
2142 Don't recognize option --file, if the functionality is not there.
2143 Likewise for --header; moreover, recognize --he and --h as shortcuts
2144 for --help in that case.
2146 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2147 matches the order of execution. No code changed.

2169 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2170 (AC_SUBST): Call it.
2171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2172 the directory specific variables; but don't call it for configure_input.
2174 2005-06-28 Derek Price <derek@ximbiot.com>
2176 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2177 addition.
2179 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2181 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2182 directory have inherent problems with special characters like spaces,
2183 due to limitations in Make syntax. Problem reported by Alexandre
2184 Duret-Lutz.
2185 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

2200 variable into diagnostic. Make the diagnostic an error, not a warning,
2201 because we really don't support spaces and suchlike in dir names.
2202 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2203 Don't worry about backslashes in srcdir; it can't happen now.

2220 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2222 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2232 (Special Shell Variables): Fix sed code this in the example.
2233 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2234 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2236 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2237 expand to the empty list. Don't use two pairs of m4_changequote,
2238 it's not necessary.
2240 2005-06-20 Derek Price <derek@ximbiot.com>
2242 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2244 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2246 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2247 * doc/autoconf.texi:
2248 Don't mention Solaris versions so much, if a
2249 problem is common to all extant versions of Solaris. Say "SunOS
2250 4" instead of "SunOS" for SunOS 4.
2251 (awk): Mention more of the limitations of traditional Awk.
2252 (cat): Don't talk about cat -v.
2254 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
2256 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2257 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

2259 to be compatible with glibc strverscmp.
2260 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2262 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2263 on Mac OS X 10.4 reported by Peter O'Gorman in:
2264 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2265 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2266 Use shell builtins rather than 'expr', to work around expr bug.
2268 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2270 * doc/autoconf.texi: "filesystem" -> "file system".
2271 "behaviour" -> "behavior".
2272 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
2273 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2274 as per POSIX.
2275 * lib/m4sugar/m4sh.m4: Likewise.

2277 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2279 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2280 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2281 to update the man page. That way, we don't have to check in new
2282 man pages every month.
2284 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2285 quotes and backslashes. Patch from Derek Price.

2295 -u, since it outputs chatter if the input files are the same.
2296 Problem reported by Ralf Menzel.
2298 2005-06-08 Derek Price <derek@ximbiot.com>
2300 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2301 renaming them since they are about to be redefined anyhow.
2303 2005-06-08 Derek Price <derek@ximbiot.com>
2305 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2306 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2307 Move m4_undefine to alphabetical order.
2309 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2311 * README: Recommend GNU M4 1.4.3 or later.
2312 * doc/autoconf.texi (Introduction): Likewise.
2313 Reword to avoid some formatting glitches.
2314 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2315 Clarify explanation of HP compiler bug.
2316 Redo example output tp match current CVS snapshot.
2317 Use @example.org in email addresses when the examples
2318 might get inadvertently cut-and-pasted into user code.
2319 Remove example of autom4te usage that doesn't seem to work now.
2320 Use modern AC_INIT (except when the example is meant to be
2321 shown with Autoconf 2.13).
2322 Update ksh info for Solaris 9 and later.
2323 KB -> kB.
2324 Modernize description of Automake versions a bit.
2325 Don't claim a future version of Autoconf is near.
2326 * doc/install.texi: Reword to avoid some formatting glitches.
2328 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2330 * doc/autoconf.texi: Add [] to examples, so that the manual
2331 follows its own advice about quoting better.
2332 Reword to avoid some formatting glitches.
2333 * doc/installt.exi: Reword to avoid some formatting glitches.
2335 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2336 Tru64 ksh pattern matching bug. Reported against Libtool by
2337 Albert Chin <libtool@mlists.thewrittenword.com> and
2338 Nicolas Joly <njoly@pasteur.fr>.
2340 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2342 m4_cdr of one-member list was [[]] (one-member list containing an
2343 empty string) instead of [] (an empty list. Callers were skewed to
2344 match this misbehaviour. As a consequence of this:
2345 - m4_foreach([x], [], [foo]) expanded to `foo', while
2346 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2347 This bug has been fixed:
2349 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2350 expand to an empty string; print error msg if called without
2351 an argument list.
2352 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2353 misbehaviour; handle [] and [[]] correctly.
2355 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2357 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
2358 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
2359 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2361 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2363 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2364 swallow records with more than 99 fields.
2365 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2366 parse the long line.
2368 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2370 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2371 swallow literals longer than 399. Reported by Ralf Wildenhues.
2372 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2373 to workaround this limitation.
2375 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2377 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2378 to gfortran, and make these the first two compiler names
2379 checked (following the general autoconf preference for gcc).
2381 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2383 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2384 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2385 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2387 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2389 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2390 expression of unbounded size when processing the --list
2391 option. This runs afoul of a limit of 399 bytes per regular
2392 expression on AIX. Problem reported by Ralf Wildenhues.
2394 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2396 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2397 * doc/autoconf.texi (Particular Headers): Reword example
2398 for multiline stdbool replacement.
2399 (Setting Output Variables): Reword text a bit. Don't
2400 give all the details about |#_!!_#|.
2401 Reword description of line replacement.
2403 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2405 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2406 now contain newlines, and substituted files must be referenced on
2407 a line alone; the sed scripts to substitute them are now very
2408 different.
2409 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2410 commands can be put in a sed script portably.
2411 * doc/autoconf.texi (Setting Output Variables): Document above
2412 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2413 use of multiline substitution.
2414 * tests/torture.at: No longer expect substitution of newline to fail.
2416 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2418 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
2419 From Ralf Menzel (trivial change).
2421 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2423 * tests/local.at: Don't attempt to check for negated character
2424 classes in shell scripts. The test was too brittle.
2426 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2428 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2429 * doc/autoconf.texi (Limitations of Builtins): Document this
2430 limitation.
2432 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2434 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2435 common code; used in many places in the tree.
2436 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
2437 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2439 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2441 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2442 messages when ac_unique_file is not found.
2443 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2444 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2445 commands, for consistency with AC_MSG_ERROR and such.
2447 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2449 * bin/Makefile.am: Merge the two rules for creating scripts.
2451 2005-05-23 Stepan Kasal <kasal@ucw.cz>
2453 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
2454 obsolete; it was never documented.
2455 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2457 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2459 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2460 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2461 (ac_top_builddir): ... this ...
2462 (ac_top_build_prefix): ... to this; the old name is also kept, for
2463 backward compatibility.
2464 (ac_top_builddir_sub): New variable, without the trailing slash,
2465 always nonempty.
2466 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2467 * doc/autoconf.texi (Configuration Actions): Rename
2468 ac_top_builddir to ac_top_build_prefix.
2469 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2470 at_top_builddir to at_top_build_prefix.
2471 * lib/autotest/general.m4 (AT_INIT): Likewise.
2473 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2475 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2476 of confdefs.h .
2478 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2480 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2481 argument to m4_foreach. I guess it was necessary in the past,
2482 but I think it's a no-op now.
2484 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2486 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2487 ``cat <<_ACEOF'' commands to one.
2488 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2489 * lib/autoconf/status.m4: On various places, use expr instead of
2490 ``echo|sed.''
2491 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2492 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2493 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2494 a range.
2495 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2496 the wrong patterns between ``case'' and ``esac.'' The previous
2497 code had false positives.
2499 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2501 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2502 as on 2005-05-02.
2503 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2504 Mention LIBOBJDIR.

2544 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2546 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2547 check.
2548 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2549 enough arguments, similarly as in m4_bpatsubsts.
2551 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2553 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2554 of absolute paths.
2556 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2558 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2559 for absolute directory names in one loop.
2560 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2561 abbreviations of --version and --debug.
2563 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2565 * doc/autoconf.texi (Autoconf Language): Be more precise about
2566 quoting rules. Problems noted by Stepan Kasal.
2567 Also, throughout this document, be more careful about white space.
2568 "blank", "white space", and "space" all have different meanings
2569 and we should be careful to say what we mean.
2571 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2573 Fix C++ related problems reported by Werner Lemberg.
2574 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2575 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2576 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2577 avoid problems with C++ and throw.
2578 * tests/compile.at: .cpp, not .cc.
2580 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2582 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2584 * doc/autoconf.texi (Generic Functions): Typos.
2586 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2588 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2589 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2590 set by latest automake.
2592 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2594 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2595 outputs 0 on GNU/Linux these days.
2597 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2599 * doc/autoconf.texi (Autoconf Language): Add more description
2600 about quoting heuristics.
2601 (Limitations of Builtins): Describe "set -" problems.
2603 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2605 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2606 not newline.
2608 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2609 by AC_DEFINE; it was a mistake.
2610 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2612 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2614 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2616 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2618 * doc/autoconf.texi (External Software): Quadrigraphs are not
2619 processed correctly in AS_HELP_STRING; avoid this in the examples.
2620 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2621 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2622 comment and reduce m4_default([foo], []) to [foo].
2623 (m4_strip): Update the explanation.
2625 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2627 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2628 Remove core.conftest.* too; it's generated by Tru64 5.1.
2629 Problem reported by Jennis Pruett.
2630 * lib/autoconf/functions.m4
2631 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2632 Don't bother to remove core files; AC_RUN_IFELSE should do that
2633 for you.
2635 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2637 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2639 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
2641 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

2654 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2656 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2657 as well as configure.in. Problem reported by Gregorio Guidi.
2659 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2661 * doc/autoconf.texi (Particular Functions): Use gnulib's current

2675 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2677 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2679 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2680 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2681 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2682 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2683 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2685 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2687 * NEWS: The configure command now warns you if you attempt to use
2688 a directory whose name contains a special character like space,
2689 newline, or "\".
2690 * doc/autoconf.texi (Installation Directory Variables): Allow
2691 "," in file names. Do not use \@; it's not a portable regexp.
2692 * bin/Makefile.am (edit): Likewise.
2693 * lib/Makefile.am (edit): Likewise.
2694 * tests/Makefile.am (edit): Likewise.
2695 * tests/semantics.at: Likewise.
2696 * tests/torture.at: Likewise.
2697 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2698 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2699 * doc/autoconf.texi (File System Conventions): Warn about
2700 unportable file names.
2701 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2702 (AC_INIT): Use it.
2703 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2704 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2705 ac_pwd, and quote srcdir.
2706 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2708 * doc/autoconf.texi: Fix some systematic formatting problems.
2709 ".)" needs a following @: if not at the end of a sentence, and
2710 similarly for "!)". "etc." should be preceded by a comma.
2711 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2713 2005-03-22 Bruno Haible <bruno@clisp.org>
2715 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2716 argument is often called 'build-aux'.
2718 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2720 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2721 macro AC_TRY_LINK is obsolete.
2722 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2723 `AC_CONFIG_FILES'.
2725 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2727 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2728 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2729 from a Common Lisp's `cl'.
2730 (AC_PROG_CXX): Behave according to the documentation: don't
2731 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2732 make the variable CCC precious; use `cl.exe', not `cl'.
2734 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2735 Alexandre Duret-Lutz <adl@gnu.org>
2737 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2738 /dev/null, as "configure" shouldn't read stdin, and this insulates
2739 us from problems (e.g., when testing for "cl"). Also, do this
2740 redirection before invoking "hostname" or "uname", and keep the
2741 original input stream available via...
2742 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2743 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2744 bother with "</dev/null" since it's now done at the top of
2745 'configure'.
2746 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2747 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2748 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2749 * doc/autoconf.texi (File Descriptor Macros): New section.

2751 * tests/base.at (Input/Output): New test.
2753 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2755 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2756 newline if neither \c nor -n work, as that would output two
2757 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2759 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2761 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2762 This causes that any required macros inside will get before the if.
2763 * doc/autoconf.texi (autom4te.cache): A typo.
2765 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2767 Undo previous change, except keep the change to
2768 lib/autoconf/programs.m4 that replaced grep with shell
2769 pattern-matching. This is because net-snmp configure reads stdin.
2770 Reported by Noah Misch.
2772 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2774 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2775 from /dev/null, as "configure" shouldn't read stdin, and this
2776 insulates us from problems (e.g., when testing for "cl").
2777 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2778 before invoking "hostname" or "uname".
2779 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2780 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2781 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2782 "</dev/null" since it's now done at the top of 'configure'.
2783 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2784 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2785 Also, replace grep with shell pattern-matching, to save a process.
2787 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2789 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2790 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2791 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2792 compiler.
2794 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2796 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2797 grep -q isn't portable. Improve grep -s explanation.
2798 Problem reported by Dan Manthey.
2800 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2802 * doc/autoconf.texi (Special Shell Variables): Clarify
2803 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2805 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2807 * doc/autoconf.texi: Use @acronym for DJGPP.
2808 Fix some @code's that should have been @env's, and vice versa.
2809 Sort environment variable names.
2810 Mention that shells no longer inherit IFS.
2811 Don't recommend PATH_SEPARATOR=';' so strongly.
2812 Mention that $RANDOM might expand to the empty string.
2813 "symlink" and "soft link" -> "symbolic link".
2814 Improve mktemp description (reported by Bruno Haible).
2816 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2818 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2819 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2820 Likewise.
2821 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2822 Likewise.
2824 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2826 * NEWS: Mention AT_COPYRIGHT.
2828 * tests/local.at (AT_CMP): Use diff directly on input files rather
2829 than copying them.
2831 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
2832 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
2834 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2835 and Paul Eggert <eggert@cs.ucla.edu>
2837 * tests/autotest.at (Empty test suite): New test.

2848 (Standard regular expressions): New test.
2849 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
2850 excess test name quoting.
2851 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
2852 CPPFLAGS to `configure' instead of setting it in `configure'.
2854 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
2855 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
2856 on some platforms.
2858 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
2859 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

2887 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
2889 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
2890 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2892 Try not to generated lines of unlimited length, as POSIX places a
2893 2047-byte limit on line length of portable text files.
2894 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2895 Use newline as a separator, not space.
2896 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
2897 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
2898 space.
2900 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2902 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
2903 as_func_*. Add test to check whether positional parameters
2904 are restored after function return.
2906 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
2908 * doc/autoconf.texi (Special Shell Variables): Mention _,
2909 BIN_SH, DUALCASE. Say that variables other than "status" are safe
2910 if they contain a lower-case letter. The DUALCASE problem was
2911 reported by Ralf Wildenhues.
2913 * bin/autoconf.as: Don't exit with status 0 after write failure
2914 with --help or --version.
2915 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

2920 * doc/autoconf.texi (Limitations of Usual Tools):
2921 Unicos 9 sed limitations.
2922 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

2924 Fortran 95 (newer Crays).
2926 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
2928 * man/Makefile.am (.x.1): Go back to the simple solution, but take
2929 care to echo the commands, so the user knows what's going on.
2930 Modified from a suggestion by Stepan Kasal.
2932 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
2933 with a cross reference. Derived from a suggestion by Bruce Korb.
2935 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
2937 * doc/autoconf.texi (config.status Invocation): Warn about

2940 Based on a proposed patch by Ralf Wildenhues.
2942 * man/Makefile.am (.x.1): Make sure the required generated files
2943 are up to date. Problem and original solution proposed by Stepan Kasal.

2951 2005-01-29 Stepan Kasal <kasal@ucw.cz>
2953 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2954 Update the long comment explaining it.
2956 m4_require no longer writes an ``is required by'' line to the
2957 execution stack. It contains only one bit of non-redundant
2958 information: that the macro was required, not called. And even
2959 this bit is useless in most situations: have you ever met a macro
2960 which both calls and requires the same macro?
2962 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2963 (_m4_defun_pro_outer): ... only via this macro, for the outermost
2964 macro.

2966 (m4_expansion_stack_pop): Remove the misplaced comment.
2967 (m4_require): Don't put the ``is required by'' line to the
2968 execution stack; slightly improve the out-of-a-defun error message.
2969 (_m4_divert_grow): New macro, counter for the temporary diversions.
2970 (_m4_require_call): Use it.
2971 * tests/m4sugar.at (m4_require): Expect output without the
2972 ``is required by'' messages.
2974 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2976 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2977 rather than x for expr.
2979 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2980 this is safe.
2981 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2982 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2991 * doc/make-stds.texi, doc/standards.texi: Update from masters.
2992 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
2993 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
2994 from masters, so that FileUtils.pm's update_file provide --force
2995 support.
2996 * bin/autoheader.in: Pass $force to update_file so that
2997 config.h.in is always recreated when --force.
2999 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3001 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3003 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3005 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3006 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3008 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3010 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3011 Warn about newline stripping in `` and $(). Update Solaris
3012 version to 9.
3013 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3014 X insulates us from future changes to Posix.
3015 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3016 stripping.
3018 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3020 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
3021 you cannot use AC_DEFINE to define macros containing `[' or `]'.
3023 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
3025 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
3026 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

3036 ulongval to be static, to avoid unwanted GCC warning. Problem
3037 reported by Michael Jennings via Daniel Reed; see
3038 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3040 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3042 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3047 new variables.
3049 2005-01-04 Noah Misch <noah@cs.caltech.edu>
3051 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
3052 not seem to work, assume it does set $(MAKE).
3053 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
3055 2005-01-03 Stepan Kasal <kasal@ucw.cz>
3057 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

3063 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
3064 (_m4_divert_n_stack): New macro; the expansion is
3065 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3066 otherwise.
3067 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3068 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3069 stored in _m4_divert_diversion or _m4_divert_dump.
3070 (m4_divert_pop): When the parameter is given, compare the symbolic
3071 name with the last diversion pushed on the stack. Previously, the
3072 current diversion was compared with the numeric value of the
3073 diversion given as the parameter.
3074 (m4_require): If the macro hasn't been expanded yet, call ...
3075 (_m4_require_call): this new macro.
3077 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3106 2004-12-30 Noah Misch <noah@cs.caltech.edu>
3108 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
3109 signals that the package uses Automake; a `Makefile.am' is typical but
3110 not essential. Reported by Magnus Therning.
3111 * tests/torture.at (autoreconf.): New banner.
3112 (autoreconf and non-AC configure): Rename to `Non-Autoconf
3113 AC_CONFIG_SUBDIRS'.

3159 2004-12-21 Stepan Kasal <kasal@ucw.cz>
3161 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3162 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

3289 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

3354 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

3357 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
3358 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

3380 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3382 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3383 "char c = '\200';" rather than "char c = 0x80;" as the
3384 latter doesn't conform to the strict C standard due to
3385 overflow on signed char hosts.
3387 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3388 to -qlanglvl=ansi. We don't want to disable extensions.

3450 the $1_found variable, don't test whether the file is executable;

3456 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

3466 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3468 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

3489 Problem reported by Stepan Kasal.
3491 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3493 Fix problems reported by Andreas Buening in:

3500 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3502 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3503 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3504 (trivial change). Problem and patch reported by Andrew Church in:
3505 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3507 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

3512 Also, fix some minor spacing and punctuation bugs.
3514 2004-09-02 Akim Demaille <akim@epita.fr>

3537 Remove ansi2knr.c; nobody uses it.
3538 (ansi2knr.c-url_prefix): Remove.
3539 (cvs-update): Fix test for failure. I don't know why it ever
3540 worked...
3542 * doc/autoconf.texi: Update URLs, some of which went stale.
3543 Use @uref rather than @href.
3545 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3546 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3548 * config/config.guess, config/config.sub, config/elisp-comp,
3549 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3550 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3552 * NEWS, TODO, configure.ac, bin/autoscan.in,
3553 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3554 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3570 More fixes to support spaces in the name of the build directory.
3571 This isn't a complete fix but it's an improvement.
3573 * bin/autoconf.as (autom4te_options): New var.
3574 Use it instead of appending to AUTOM4TE, so that we can allow
3575 spaces in the build directory's absolute name.
3576 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3577 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

3591 and isnan. From a suggestion by Kevin Ryde.

3596 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3598 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3599 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3600 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3602 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3604 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3605 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3606 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3607 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3608 * lib/autom4te.in (Automake-preselections): Preselect
3609 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3611 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3613 * lib/autom4te.in (Automake-preselections): Preselect
3614 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3615 trace them.
3617 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3619 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

3626 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3627 with pdksh, too. Problem reported by Patrick Welche via
3628 Gary V. Vaughan.
3629 * doc/autoconf.texi (Shellology): Note that set -o posix is
3630 useful for pkdsh, too.
3632 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3634 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require

3636 Don't fail if ENV or BASH_ENV is readonly.
3637 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

3648 * doc/autoconf.texi (File System Conventions): Warn about
3649 names like "aux". Problem reported by Eric Blake.
3651 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3652 by zero instead of array size, so that we can use any arithmetic
3653 constant expression (instead of requiring an integer constant
3654 expression). This allows us to test expressions like DBL_MAX <
3655 LDBL_MAX, which didn't conform to the C standard using the old
3656 method.
3657 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3658 now that we can do floating-point tests at compile time.
3660 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3662 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3663 and LDBL_EPSILON, as the resulting expression isn't an
3664 integer constant expression and violates the C standard.
3665 Problem reported by Nelson H. F. Beebe. Also, check
3666 for "L" suffix, and check that long double doesn't have
3667 worse range or precision than double, that mixed-mode
3668 arithmetic doesn't generate a diagnostic, that double
3669 constants fit in long double.
3671 2004-06-03 Kevin Ryde <user42@zip.com.au>
3673 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3674 malloc(0) and realloc(NULL,size).
3676 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3677 Bob Proulx.
3679 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3681 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3682 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3683 by Jim Meyering.
3685 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3687 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3688 can be rewritten using if-then-else. Suggested by Bruno Haible.
3690 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3692 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3693 Problem reported by Stepan Kasal.
3695 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3697 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3698 change). Patch reported by Ralf Wildenhues in
3699 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3701 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3702 function F exists if the compiler and linker let you compile an
3703 expression like (F != 0). Recent versions of GCC optimize away
3704 the reference to F in that case, since every function address must
3705 be nonzero, so the link succeeds even if F does not exist.
3706 Problem reported by Manu in
3707 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3709 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3710 "Unix". Many uses changed.
3711 (Limitations of Builtins): Explain better why the ! command isn't
3712 portable.
3714 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3716 * lib/autom4te.in (Automake-preselections): Preselect
3717 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3719 2004-05-19 Kevin Ryde <user42@zip.com.au>
3721 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3722 referencing AC_FUNC_STRERROR_R.
3724 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3725 note pessimistic assumption when cross compiling.
3727 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3729 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3730 (until 2004) invoked subcommands with sh -e, contra POSIX.
3731 Reported by Kevin Ryde.
3733 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3735 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3736 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3737 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3738 `test -f " /usr/bin/grep"', which _always_ failed.
3739 (AC_PROG_SED): Ditto bogus PATH fix.
3740 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3741 requires that grep correctly supports _multiple_ `-e' options, rather
3742 than stating only that grep should accept `-e'.
3744 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3746 Port to C99, which requires that 'exit' be declared.
3748 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3749 to ensure that stdlib.h is included.
3750 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3751 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3752 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3753 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3754 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3755 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3756 when using 'exit' in a test; C99 requires that 'exit' be declared.
3758 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3760 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3761 now prefers 'grep' implementations that accept -e.
3762 (Limitations of Usual Tools): Describe problems of traditional
3763 egrep and fgrep with long input lines, and of traditional grep
3764 with -e.
3765 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3766 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3767 All callers changed. Append /usr/xpg4/bin to the PATH, for
3768 Solaris.
3769 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3770 the user with complaints about multiple -e options.
3771 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3772 Define it with AC_PROG_GREP.
3773 * configure.ac (AC_PROG_GREP): Add.
3774 * lib/freeze.mk (GREP): New macro.
3776 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3778 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3779 a possible candidate only after all others fail, rather than
3780 consulting it first. This improves backward compatibility by
3781 better reflecting the way shell selection occurred in previous
3782 versions of Autoconf, and should help to avoid triggering latent
3783 problems in other packages, such as the one in Automake where zsh
3784 is not handled robustly:
3785 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3786 Although it is not Autoconf's responsibility to work around
3787 problems in Automake, it nevertheless makes sense to avoid
3788 introducing unnecessary incompatibilites.
3790 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3791 Gary V. Vaughan <gary@gnu.org>
3793 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3794 how deeply nested we are when a suitable tool is found, set the
3795 ac_path_TOOL_found flag.
3796 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3797 nested we are in this macro. Break out of all 3 nested loops if
3798 ac_path_TOOL_found is set.
3800 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3802 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3803 of the _AS_PATH_WALK loop too if GNU flavor is found.
3805 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3807 * doc/autoconf.texi (Limitations of Make): Update documentation
3808 for `$<'. New entry `Long lines', based on a report from Simon
3809 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3810 paragraph about DJGPP, based on a mail from Richard Dawe.
3812 2004-04-20 Paul Eggert <eggert@twinsun.com>
3814 * tests/c.at (C keywords): Don't assume that GCC supports
3815 "restrict" and "inline", as sufficiently-old GCC versions do not
3816 (also, GCC configured to be in pedantic C89 mode does not).
3817 Problem reported by Sumit Pandya in:
3818 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3820 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3821 consider -g to work if it generates warnings when plain compiles
3822 don't. Problem reported by Braden McDaniel in:
3823 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3825 * doc/autoconf.texi (Slashes): New section, to document a problem
3826 reported by Jim Meyering in:
3827 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3829 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3830 linker output files before linking, to work around IRIX 6 linker bug.
3831 Problem reported by Rainer Orth in:
3832 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3834 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3836 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3837 best tool so far counter rely on the tool path variable name to
3838 avoid checks for one tool being affected by the results of running
3839 the length check on a previous tool.
3841 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3842 match expression argument, as different greps have different
3843 regular expression flavours.
3844 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3845 literals.
3846 (AC_PROG_EGREP): Pass 'EGREP$'.
3847 (AC_PROG_GREP): Pass 'GREP$'.
3849 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3851 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3852 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
3854 2004-03-29 Paul Eggert <eggert@twinsun.com>
3856 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3857 Types, Specific Compiler Characteristics, System Services,
3858 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3859 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3860 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3861 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
3862 Likewise.
3863 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
3864 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
3865 AC_TYPE_OFF_T): Likewise.
3866 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
3867 Likewise.

3870 pacify libtool 1.5.2. Fix quoting problems in sed command.
3872 2004-03-28 Paul Eggert <eggert@twinsun.com>
3874 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3875 now defines HAVE_DECL_TZNAME if it is declared, when
3876 HAVE_STRUCT_TM_TM_ZONE is not defined.
3877 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3878 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3879 for HAVE_TZNAME.
3881 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3883 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
3884 superfluous backslashing of quotes (") in sed expressions;
3885 thanks to Paul Eggert.
3887 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
3889 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
3890 Fortran compiler is ifort, also added pghpf; thanks to Nelson
3891 H. F. Beebe for the bug report.
3893 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3895 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3896 quoted -cmdline argument in Portland Group compiler (bug
3897 reported by Jeffrey J. Barteet).
3899 2004-03-25 Kevin Ryde <user42@zip.com.au>
3901 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

3923 AC_CHECK_TOOLS.
3924 (Specifying Names): Document the reason for these future
3925 behavioral changes.

3927 new macros.
3928 * NEWS: Document these changes.
3930 * doc/autoconf.texi: Avoid macros with unbraced arguments,

3936 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3937 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3938 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3939 vowel.
3940 (AC_CHECK_ALIGNOF): New macro.
3941 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
3942 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
3943 those for sizeof.
3945 2004-03-03 Paul Eggert <eggert@twinsun.com>
3947 * bin/Makefile.am (edit): Don't use $< in a context where
3948 POSIX doesn't require support for it. Use $@.in instead.
3949 Problem reported by Anthony N. Frasso in
3950 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3951 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3953 2004-02-23 Gary V. Vaughan <gary@gnu.org>

3981 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3982 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3983 Darwin uses -lcrt2.o and there's little point to cataloging all
3984 the system variants. Partial fix reported by Andreas Waechter in:
3985 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

3999 refer to the correct file.
4000 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4001 the behavior of the third argument.
4002 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4003 correctly the behavior of the third argument. Document

4107 2004-01-26 Paul Eggert <eggert@twinsun.com>
4109 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4110 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4111 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4112 not <inttypes.h>. Problem reported by Tim Mooney in
4113 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4114 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4115 Likewise.
4117 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4118 otherwise "make check" fails because it forbids cmp (I guess
4119 because cmp treats files as binary on DOS-like systems).
4121 * tests/mktests.sh: Update copyright date to 2004, since some tests
4122 have changed in 2004.
4124 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4126 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4127 non-truncating sed or gsed program in PATH.
4128 * tests/acprograms.at: Add it.
4129 * doc/autoconf.texi (Particular Programs): Document it.
4130 * NEWS: Updated.
4132 2004-01-15 Paul Eggert <eggert@twinsun.com>
4134 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4135 -std1 disables some useful extensions on Tru64. Problem reported
4136 by N. Lichtmaier in
4137 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4139 2004-01-14 Paul Eggert <eggert@twinsun.com>
4141 * doc/autoconf.texi (Programming in M4sh): Document that
4142 AS_MKDIR_P succeeds if the destination is a symbolic link
4143 to an existing directory.
4144 (Limitations of Usual Tools): Note that mkdir -p might not
4145 succeed on symlinks to directories.
4147 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4149 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4150 * bin/autoheader.in: Grammar fix in message.
4151 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

4157 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4159 2004-01-10 Jim Meyering <jim@meyering.net>
4161 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4163 2004-01-09 Paul Eggert <eggert@twinsun.com>
4165 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4166 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4167 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4168 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4169 AC_COMPILE_IFELSE, since we now assume our caller invokes
4170 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4171 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4172 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4173 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4175 2004-01-07 Paul Eggert <eggert@twinsun.com>
4177 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4178 `"'...'"`, as it's confusing (and I suspect it may not work on
4179 some platforms). The code was incorrect anyway, as it assumed
4180 that \$ evaluated to itself in that context. Reported by
4181 Alexandre Duret-Lutz.
4183 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4185 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4186 and _LT_AC_TAGCONFIG.
4188 2004-01-06 Paul Eggert <eggert@twinsun.com>
4190 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4191 example, and add more examples. Reported by Eric Sunshine.
4193 2004-01-05 Paul Eggert <eggert@twinsun.com>
4195 * doc/autoconf.texi (Limitations of Usual Tools):
4196 Remove warning against "rm -fr" introduced yesterday; it
4197 was a false alarm.
4199 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4200 autoscan, autoupdate, ifnames): Don't use chmod -w.
4201 * lib/Makefile.am (autom4te.cfg): Likewise.
4202 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4203 "chmod -w".
4205 2004-01-04 Paul Eggert <eggert@twinsun.com>
4206 Paolo Bonzini <bonzini@gnu.org>
4208 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4209 by doing lineno substitution only on lines containing "$LINENO".
4211 2004-01-04 Paul Eggert <eggert@twinsun.com>
4213 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4214 Use "rm -f" to remove conftest.sed, not plain "rm".
4215 Bug reported by David Relson in
4216 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4218 * Makefile.am (autom4te-update):
4219 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4220 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4221 * doc/autoconf.texi (Guidelines): Likewise.
4222 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
4223 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.

4225 * lib/autotest/general.m4 (AT_INIT): Likewise.
4226 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
4227 * tests/Makefile.am (clean-local): Likewise.
4228 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4229 srcdir): Likewise.
4230 * doc/autoconf.texi (Limitations of Usual Tools):
4231 Warn against "rm -fr".
4233 2004-01-03 Paul Eggert <eggert@twinsun.com>
4235 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4236 -c -o might not work. From a suggestion by Kevin Ryde.
4237 (C Compiler, Generating Sources, Limitations
4238 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4239 Don't put '-o' after non-options, as POSIX doesn't allow this.
4240 Mention that cc's name might be gcc or c89 or whatever.
4242 2004-01-04 Kevin Ryde <user42@zip.com.au>
4244 * doc/autoconf.texi: Add various further index entries.
4246 2003-12-29 Paul Eggert <eggert@twinsun.com>
4248 * bin/autoreconf.in (autoreconf_current_directory):
4249 Fix typo: mkdir without umask arg.
4251 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4253 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4254 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4255 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4256 explanation clearer.
4258 2003-12-24 Andreas Schwab <schwab@suse.de>
4260 * doc/autoconf.texi (Default Includes): Fix misspelling of
4261 AC_INCLUDES_DEFAULT.
4263 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4265 * configure.ac: Test if sh -n works.
4266 * configure: Regenerate.
4267 * tests/atlocal.in: Store the result here.
4268 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4269 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4270 of explicitly testing.
4271 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4272 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4273 * tests/tools.at (Syntax of the shell scripts): Simplify
4274 using AT_CHECK_SHELL_SYNTAX.

4289 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4290 macros.
4291 (AS_SHELL_SANITIZE): Move reinvocation code from
4292 _AS_LINENO_WORKS, use it to find out if shell
4293 functions work.
4294 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4295 does not work.
4296 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
4297 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
4298 was called.

4308 (&sizes): New.
4309 Use them.

4311 them on the fly.
4313 2003-11-24 Akim Demaille <akim@epita.fr>
4315 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4356 2003-11-15 Kevin Ryde <user42@zip.com.au>
4358 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4359 than $target since the latter is not usual, add guidelines on when to
4360 use or not use the system type.

4364 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

4384 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

4541 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4542 -mGLOB_options_string stuff for Intel ifc, which can cause
4543 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
4544 pattern-matching instead of grep.
4546 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

4566 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4567 cache variable instead of $G77 to decide whether to include -O2,
4568 since $G77 is specific to Fortran 77.
4570 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4572 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
4573 free" flag. Re-order flags tested into rough order of popularity.
4575 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4577 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4578 arguments so that it can be used with syntax identical to
4579 AC_PROG_F77, and so that we can more easily decide to
4580 remove/deprecate the DIALECT optional argument in the future if it
4581 proves troublesome.
4582 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4583 non-freeform-supporting compilers. Document freeform flags.
4585 2003-10-03 Akim Demaille <akim@epita.fr>
4587 * configure.ac: Look for emacs, not macs.
4588 Reported by Eric Sunshine.
4590 2003-10-03 Akim Demaille <akim@epita.fr>
4592 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
4593 * bin/autoreconf.in (autoreconf_current_directory): Create the
4594 AUX_DIR if needed, for sake of automake --add-missing etc.
4595 Suggested by Alexandre Duret-Lutz.
4597 2003-10-03 Akim Demaille <akim@epita.fr>
4599 * configure.ac: Quotation and formatting changes.
4600 (EMACS): Don't set it if it is not recent enough to support
4601 autoconf-mode.el.
4602 From Eric Sunshine.
4604 2003-10-02 Akim Demaille <akim@epita.fr>
4606 * bin/ifnames.in (&scan_file): Skip C++ comments.

4616 Version 2.57f.
4618 2003-09-30 Paul Eggert <eggert@twinsun.com>
4620 * lib/Autom4te/XFile.pm: Use Errno.
4621 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
4622 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
4624 2003-09-30 Akim Demaille <akim@epita.fr>
4626 * config/announce-gen (&print_news_deltas): Extracted from...
4627 (&print_changelog_deltas): here.
4628 (&news_file): Rename as...
4629 (@news_file): this.
4631 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
4633 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
4634 have been created when invoking the compiler.

4639 Version 2.57e.
4641 * config/mkinstalldirs: Upgrade.
4643 2003-09-28 Paul Eggert <eggert@twinsun.com>
4645 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
4646 Problem reported by Lars J. Aas in
4647 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4648 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4649 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4650 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4652 2003-09-26 Akim Demaille <akim@epita.fr>
4654 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4655 directory for AC_CONFIG_COMMANDS' first argument exists.
4656 This makes valid the invocation of _AC_SRCPATH that follows.
4657 Reported by Eric Sunshine.
4658 * doc/autoconf.texi (Configuration Commands): Adjust.
4660 2003-09-26 Akim Demaille <akim@epita.fr>
4662 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4663 Reported by Ralf Corsepius.
4665 2003-09-26 Akim Demaille <akim@epita.fr>
4667 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4668 arguments.
4669 Actually, use AU_ALIAS.
4670 From Bruno Haible.
4672 2003-09-26 Paul Eggert <eggert@twinsun.com>
4674 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
4675 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
4676 Problem reported by Eric Sunshine in:

4679 2003-09-26 Akim Demaille <akim@epita.fr>
4681 The test suite are sometimes assigning timings incorrectly.
4682 Reported by Henk Krus.
4683 Diagnosed by Nicolas Joly.
4685 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4686 AT_help_all.
4687 Instead of making AT_help a sequence of assignments to grow
4688 $at_help_all, just make AT_help_all be the growing contents of
4689 $at_help_all, and make a single assignment in...
4690 (AT_INIT): here.
4691 (at_times_skip): Flip the meaning and rename as...
4692 (at_times_p): this.
4693 (AT_INIT): When summarizing the test that ran, remove
4694 $at_times_file after use, and check it is present before trying to
4695 use it.
4697 2003-09-25 Akim Demaille <akim@epita.fr>
4699 Version 2.57d.
4701 * bin/Makefile.am (edit): Handle '@configure_input@'.
4702 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
4703 (ifnames): chmod -w.
4704 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4705 executables, not bin/ executables! Otherwise all the magic needed
4706 to find non installed files is turned off. This caused a failure
4707 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4708 as found in its environment (sent by tests/autoreconf): pointing
4709 to bin/autom4te that could not find its files.
4710 * tests/mktests.sh: Force the replacement of generated files, for
4711 the sake of "mv" program that are interactive when overwriting a
4712 -w file.
4713 * config/install-sh: Upgrade from CVS Automake.
4715 2003-09-23 Paul Eggert <eggert@twinsun.com>
4717 * doc/autoconf.texi (Limitations of Builtins): Document test -h
4718 versus test -L issues.
4720 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4721 Paul Eggert <eggert@twinsun.com>
4723 Trivial change to support GCC's configuration procedure.
4724 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4725 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4726 about inconsistency if the preprocessor is set to give errors for
4727 any warning.
4728 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4730 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
4732 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
4733 and XFile.pm from Automake.

4743 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
4744 from masters.
4746 2003-09-12 Akim Demaille <akim@epita.fr>
4748 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
4749 not asm/types.h.
4751 2003-09-11 Akim Demaille <akim@epita.fr>
4753 * doc/autoconf.texi (Header Portability): linux/random.h.
4754 From Peter Hendrickson.
4756 2003-09-10 Akim Demaille <akim@epita.fr>
4758 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4759 willing to edit the output files.
4761 2003-09-10 Akim Demaille <akim@epita.fr>
4763 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4764 and AC_FC_FREEFORM.
4765 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4766 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
4768 2003-09-09 Akim Demaille <akim@epita.fr>
4770 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
4771 Reported by Gary Vaughan.
4772 * bin/autom4te.in (handle_m4): Likewise.
4774 2003-09-09 Akim Demaille <akim@epita.fr>
4776 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
4777 trailing files.
4779 2003-09-07 Paul Eggert <eggert@twinsun.com>
4781 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
4782 Improve the accuracy of the wording about obsolescence.
4783 From a suggestion by Ian Lance Taylor in
4784 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
4786 2003-09-05 Paul Eggert <eggert@twinsun.com>
4788 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4789 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4791 2003-09-04 Akim Demaille <akim@epita.fr>
4793 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4794 AC_FUNC_WAIT3.
4796 2003-09-04 Akim Demaille <akim@epita.fr>
4798 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4799 (freeze): When exiting, use $exit_code.
4800 * lib/autoconf/fortran.m4: Comment changes.
4802 2003-09-04 Akim Demaille <akim@epita.fr>
4804 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
4806 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4808 Add support for newer Fortran dialects. The F77 interface is
4809 unchanged, and continues to support Fortran 77. New FC macros
4810 correspond to all the old F77 macros, with output variables FC,
4811 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4812 available dialect, but older dialects can be specified. There are
4813 new macros AC_FC_SRCEXT to set the source extension, and
4814 AC_FC_FREEFORM to accept free-form source files.
4816 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4817 New macros.
4818 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
4819 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

4821 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

4829 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
4830 AC_FC_SRCEXT, AC_FC_FREEFORM):
4831 New macros.

4833 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
4834 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
4835 Rewrite in terms of the above.
4836 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
4837 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
4838 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
4839 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
4841 2003-09-02 Paul Eggert <eggert@twinsun.com>
4843 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
4844 Document problems with timestamp resolution that 'make', 'cp -p', and
4845 'touch -r' have.
4847 2003-08-27 Akim Demaille <akim@epita.fr>
4849 * tests/m4sugar.at (cross_warning): Make sure to enable the
4850 output, so that we can track spurious m4sugar output.
4851 * tests/local.at: Require 2.57.
4852 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4853 are defaulted by AT_CHECK anyway.
4854 Use AT_CHECK_AUTOM4TE.
4855 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4856 missing dnl.
4858 2003-08-27 Akim Demaille <akim@epita.fr>
4860 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4861 when -Wobsolete is set.
4862 Set it on by default.
4863 Suggested by Klee Dienes.
4865 2003-08-27 Akim Demaille <akim@epita.fr>
4867 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

4874 after AC_OUTPUT.
4876 2003-08-25 Akim Demaille <akim@epita.fr>
4878 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

4907 2003-08-22 Akim Demaille <akim@epita.fr>
4909 Output stack traces in warnings.
4911 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
4912 Replace the former...
4913 (m4_warn): Pass the call stack to _m4_warn.
4914 * bin/autom4te.in: Adjust to output the call stack.
4915 * tests/m4sugar.at (m4@&t@_warn): Adjust.
4917 2003-08-22 Akim Demaille <akim@epita.fr>
4919 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
4920 * bin/autom4te.in: Adjust.
4922 2003-08-21 Akim Demaille <akim@epita.fr>
4924 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
4925 (&verbose): Remove.
4926 (&getopt): Adjust the note and verb channels, depending upon
4927 --verbose.
4928 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
4929 * bin/autoupdate.in: Adjust.
4930 Use &verb, not &verbose.
4932 2003-08-21 Akim Demaille <akim@epita.fr>
4934 * bin/autoheader.in (&parse_args): Use &parse_warnings and
4935 &parse_WARNINGS.
4936 ($help): Use Autom4te::ChannelDefs::usage.
4937 * bin/autoscan.in: Use Autom4te::ChannelDefs.
4938 * lib/Autom4te/General.pm: Don't export error: you don't own it.
4940 2003-08-21 Akim Demaille <akim@epita.fr>
4942 First stab at preserving warnings between calls to autom4te,
4943 including when the cache is used.
4945 There are still several issues: (i) there are too many runs of m4
4946 (one for include, one for warnings, and some more), (ii) warnings
4947 spreading on several lines are not handled gracefully, (iii) the
4948 code meant to have the call stack display for errors does not work
4949 (its handling should move from m4 to autom4te).
4951 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4952 Use them.
4953 (@preselect): Add m4_warn.
4954 ($exit_status): Remove, use $exit_code.
4955 ($help): Use Autom4te::ChannelDefs::usage.
4956 (&handle_m4): No longer define the m4_warnings.
4957 At each run, extract and report the warnings.
4958 Always cache the result, including if the exit status is on
4959 failure, since if nothing changes, we should result in the same
4960 failure, hence we can use the cache.
4961 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4962 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4963 Remove.
4964 (m4_warn): Redefine as a do-nothing: it is its invocation that
4965 matters, as warnings are now reported via traces.
4966 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4967 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4968 the latter reveals calls to the former.
4970 Adjust the tests.
4972 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4974 2003-08-21 Akim Demaille <akim@epita.fr>
4976 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
4977 Use them.
4979 2003-08-21 Akim Demaille <akim@epita.fr>
4981 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4982 forward order.
4983 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4984 (&parse_warnings): Accept a list of warning requests.
4985 (&usage): Return a string, not a side effect.
4986 (cross): New warning category.
4988 2003-08-21 Akim Demaille <akim@epita.fr>
4990 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4991 (&require_configure_ac): Accept an optional directory argument.
4992 ($configure_ac): Remove.
4993 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4994 (&catfile): Remove.
4995 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4996 * bin/autoscan.in: Adjust.
4998 2003-08-20 Akim Demaille <akim@epita.fr>
5000 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5001 Reported by Alexandre Duret-Lutz.
5003 2003-08-20 Akim Demaille <akim@epita.fr>
5005 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5006 * bin/autom4te: Adjust.
5007 In particular, be Autoconf tools are really silent when properly
5008 working, bind the verbosity of the 'note' channel to $verbose.
5009 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5010 (&xsystem, &contents): Remove, since they are exported by...
5011 * lib/Autom4te/FileUtils.pm: this.
5012 More perldoc.
5013 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5014 * lib/Autom4te/FileUtils.pm: here.
5016 2003-08-20 Akim Demaille <akim@epita.fr>
5018 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5019 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5020 from CVS Automake.
5022 2003-08-20 Akim Demaille <akim@epita.fr>

5025 (autom4te-update): New.
5026 * Makefile.cfg (update): Bind autom4te-update.
5028 2003-08-19 Derek Price <derek@ximbiot.com>
5030 * lib/autotest/general.m4: Comment various HELP_* diversions.
5031 (PARSE_ARGS_BEGIN): New section for option parsing related
5032 initialization.
5033 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
5034 package specific options and associated help.

5038 * config/announce-gen, Makefile.cfg: New.
5039 * Makefile.am: Adjust.
5040 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
5042 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5044 * lib/autom4te.in (Automake-preselections): Preselect
5045 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5046 and m4_sinclude.
5048 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5050 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
5051 (Autoconf-without-aclocal-m4): ... this new language.
5052 * doc/autoconf.texi (autom4te Invocation): Mention
5053 Autoconf-without-aclocal-m4.
5055 2003-08-18 Derek Price <derek@ximbiot.com>
5057 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
5058 RUN-IF-PASS optional arguments.

5067 STDOUT & STDERR arguments.
5069 2003-08-14 Derek Price <derek@ximbiot.com>
5071 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5072 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5073 shorter column three. Add DESCRIPTION to log file content.
5075 2003-08-13 Derek Price <derek@ximbiot.com>
5077 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5078 output.
5080 2003-08-12 Derek Price <derek@ximbiot.com>
5082 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5083 (AT_CHECK_NOESCAPE): Move core functionality to...
5084 (_AT_CHECK): ...this new macro.
5086 2003-08-07 Derek Price <derek@ximbiot.com>
5088 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5089 (AT_CHECK_NOESCAPE): ...to this new macro.
5091 2003-07-31 Paul Eggert <eggert@twinsun.com>
5093 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5094 in Bash 2.01. Problem reported by Brian Gough in
5095 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5097 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5099 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5100 -lcrt1.o, for OS X. (trivial change)
5102 2003-07-07 Paul Eggert <eggert@twinsun.com>
5104 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5105 inside '#ifndef __cplusplus'. Problem reported by
5106 Bob Friesenhahn.
5108 2003-07-06 Bill Clarke <llib@computer.org>
5110 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5111 'long', not 'int', for benefit of Sun's recent C++ compilers
5112 (trivial change). See:
5113 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5114 (This really should be 'intptr_t', not 'long', but that would
5115 take more work.)
5117 2003-06-25 Akim Demaille <akim@epita.fr>
5119 * lib/Makefile.am (autom4te.cfg): Make it read only.
5120 Depend on Makefile since it contains substitutions.
5121 From Paolo Bonzini.
5122 * lib/autom4te.in (args): Add local.at? for Autotest args.
5123 This change was made on autom4te.cfg which is generated.
5124 Reported by Raja R. Harinath.
5126 2003-06-25 Akim Demaille <akim@epita.fr>
5128 * doc/autoconf.texi (Header Portability): sys/mount.h.
5129 From Gareth McCaughan.
5131 2003-06-23 Akim Demaille <akim@epita.fr>
5133 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5134 not all of them. This fixes 1. the fact that when testing
5135 Autoconf there are many many config.log, 2. the incorrect use of
5136 top_srcdir to find config.log.
5137 Don't mix the detailed output of failed test with the summary of
5138 failures. Rather, append detailed log afterwards.
5140 2003-06-23 Akim Demaille <akim@epita.fr>
5142 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5143 always run: output config.log on $at_group_log.
5145 2003-06-23 Akim Demaille <akim@epita.fr>
5147 * tests/torture.at (#define header templates): Don't use quotes in
5148 C++ comments as it puzzles Emacs' sh font-lock-mode.
5150 2003-06-23 Akim Demaille <akim@epita.fr>
5152 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5153 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5154 * tests/atspecific.m4: Rename as...
5155 * tests/local.at: This.
5156 * tests/suite.at: Move the globals into...
5157 * tests/local.at: here.
5158 * tests/Makefile.am: Adjust.
5159 * doc/autoconf.texi (testsuite Scripts): Adjust.
5161 2003-06-21 Kevin Ryde <user42@zip.com.au>
5163 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5164 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5165 ensuring we add -std1 for full-ANSI.
5167 * doc/autoconf.texi (hdrindex): New macro.
5168 Add index entries for portability of various standard header files.
5170 2003-06-20 Akim Demaille <akim@epita.fr>
5172 * configure.ac: Bump to 2.57b.
5174 2003-06-20 Akim Demaille <akim@epita.fr>
5176 Version 2.57a.
5178 2003-06-20 Akim Demaille <akim@epita.fr>
5180 * bin/autom4te.in: Don't rely on $HOME being defined.
5181 Reported by Marc Espie as PR/233.
5183 2003-06-20 Akim Demaille <akim@epita.fr>
5185 * lib/autotest/general.m4: Use at_times_file only if used.
5186 From Nicolas Joly.
5188 2003-06-20 Akim Demaille <akim@epita.fr>
5190 * config/config.guess, config/config.sub, config/elisp-comp,
5191 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5192 Update from masters.
5194 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5196 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5197 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5198 (TEST_SCRIPT): New diversion.
5199 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5200 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5201 (AT_INIT): Support for expected failures.
5203 2003-06-02 Akim Demaille <akim@epita.fr>
5205 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5206 changes.
5207 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5208 Autoconf nor Automake.
5209 (&contents): New, from Automake.
5210 PODify.
5212 2003-05-28 Paul Eggert <eggert@twinsun.com>
5214 * NEWS, doc/autoconf.texi (Particular Functions),
5215 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5216 is the inverse of localtime.
5218 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5220 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5221 (handle_exec_errors): New function. Work around $! being
5222 altered by WEXITSTATUS.
5223 (xqx, xsystem): Use handle_exec_errors.
5225 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5227 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5228 Do not call `_exit()', simply modify `$?'.
5229 (xsystem): Reset $! before running system, and check it afterward.
5230 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5231 63 for version mismatches.
5233 2003-05-23 Akim Demaille <akim@epita.fr>
5235 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5236 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5237 the middle of a line).
5238 * lib/m4sugar/m4sugar.m4: Likewise.
5239 Remove useless spaces in comments.
5241 2003-05-23 Akim Demaille <akim@epita.fr>
5243 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5244 exit 63, so that we (or Automake's "missing") can tell the
5245 difference with a plain failure.
5246 * doc/autoconf.texi (Notices): Adjust.
5248 2003-05-23 Akim Demaille <akim@epita.fr>
5250 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5251 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5252 White spaces cleanup.
5254 2003-05-22 Jim Meyering <jim@meyering.net>
5255 Paul Eggert <eggert@twinsun.com>
5257 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5258 Remove `#include <stdlib.h>' from the list; we should never
5259 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5260 resulting namespace pollution would cause other tests to fail.
5261 Configure scripts run with some older versions of g++ and HP's
5262 aCC would fail due to such an #include. Problems reported by
5263 Matthew Mueller in <http://bugs.debian.org/120704> and by
5264 Keith Bostic in
5265 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5266 In the test, use the test declaration before including <stdlib.h>,
5267 as that's closer to how it'll be used.
5269 2003-05-23 Akim Demaille <akim@epita.fr>
5271 * doc/autoconf.texi (Header Portability): ucred.h.
5272 From Ian Redfern.
5274 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5276 Overhaul Autotest's logging: generate separate log files
5277 in testsuite.dir/NNN/testsuite.log, and append them to
5278 testsuite.log instead of re-running the test verbosely.
5280 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5281 file descriptor, write 0 to at_status_file instead of setting
5282 at_status=0, initialize some new variables (at_status_file,
5283 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5284 to rerun the tests, instead append the at_group_log to the
5285 at_suite_log when a test fails.
5286 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5287 with the AS_MESSAGE_LOG_FD redirected to stdout.
5288 (AT_CLEANUP): save the output status in $at_status_file
5289 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5290 its original place.
5291 (AT_CHECK): since tests are run with a redirected stdout,
5292 and used to be re-run in verbose mode, turn some $at_verbose
5293 into echo, and don't redirect the output of testing stdout
5294 and stderr.
5296 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5297 the name of the debugging directory and information about
5298 its contents.
5300 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5302 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5303 parameter.
5305 2003-05-22 Akim Demaille <akim@epita.fr>
5307 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
5308 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
5309 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

5325 Whitespace clean up.
5326 Suggested by Jim Meyering.
5328 2003-05-22 Akim Demaille <akim@epita.fr>
5330 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
5331 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
5332 Reported by Jim Meyering.
5334 2003-05-22 Akim Demaille <akim@epita.fr>
5336 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

5351 it to eval.
5353 2003-05-21 Akim Demaille <akim@epita.fr>
5355 * bin/autoupdate.in ($m4): Fix quotation.

5358 2003-05-19 Paul Eggert <eggert@twinsun.com>
5360 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

5367 AC_CHECK_HEADERS_NEW): New tests.
5369 2003-05-17 Akim Demaille <akim@epita.fr>
5371 * lib/autoconf/functions.m4: Use the default includes so that
5372 memcmp be declared before being tested.
5373 Reported by Sander Niemeijer.
5374 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
5375 * doc/autoconf.texi (Default Includes): Document
5376 AC_INCLUDES_DEFAULT.
5378 2003-05-17 Akim Demaille <akim@epita.fr>
5380 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
5381 * doc/autoconf.texi (Obsolete Macros): Adjust.
5382 Reported by Werner LEMBERG and Debian Bug 190886.
5384 2003-05-16 Akim Demaille <akim@epita.fr>
5386 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
5387 user name space clashes.
5388 Reported by Bruno Haible.
5390 2003-05-16 Akim Demaille <akim@epita.fr>
5392 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5393 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
5394 them uniform, and more robust to Perl special characters.
5395 Reported by Martin Mokrejs.
5397 2003-05-14 Akim Demaille <akim@epita.fr>
5399 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
5401 2003-05-14 Akim Demaille <akim@epita.fr>
5403 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

5408 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
5409 message.
5410 From Matthias Andree.
5412 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>

5415 and truncate.
5417 2003-05-06 Akim Demaille <akim@epita.fr>
5419 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5420 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5421 by aclocal.m4 is changed it might require the importing of another
5422 m4 extension file, i.e., aclocal must be run.
5424 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5425 (&parse_args): Use --force with aclocal if required and supported.
5426 (&autoreconf_current_directory): Use &run_aclocal.
5428 2003-05-06 Akim Demaille <akim@epita.fr>
5430 Lock autom4te's cache.
5432 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
5433 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5434 argument instead of a file name, so that the request file remains
5435 open during the whole autom4te run.
5436 ($icache_file): New.
5437 (&freeze): Lock the $icache_file.
5439 2003-04-29 Derek Price <derek@ximbiot.com>
5441 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5442 seperator with m4_append_uniq(). It doesn't work.
5443 (AT_CLEANUP): Add `;' to end of at_help_all.
5444 (AT_INIT): Allow --keywords to be specified more than once. When
5445 grepping $at_help_all for keywords, use the field and keyword
5446 seperators to ensure a complete keyword match. Alter at_prev handling
5447 to support the new --keywords behavior.
5449 2003-04-27 Karl Berry <karl@freefriends.org>
5451 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5452 align better with others. I also made some of the individual
5453 entries on one line, for brevity and to make it easier for me to
5454 sort my dir-example file in the Texinfo distribution :).
5456 2003-04-12 Jim Meyering <jim@meyering.net>
5458 * NEWS: Mention the new macro.
5459 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.
5460 * doc/autoconf.texi (C Compiler): Describe AC_C_RESTRICT.
5461 * tests/c.at: Test AC_C_RESTRICT.

5472 From Ilya Zakharevich.
5474 2003-04-08 Akim Demaille <akim@epita.fr>
5476 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
5477 net/if.h, stdlib.h.

5489 2003-04-01 Akim Demaille <akim@epita.fr>
5491 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
5492 (AC, AT, MS): these.
5493 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
5494 New.
5495 Use them.
5496 * doc/Makefile.am (CLEANFILES): Adjust.
5497 (TEXI2DVI): Make it --batch.
5499 2003-03-31 Derek Price <derek@ximbiot.com>
5501 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
5502 which removed the main loop.
5503 Thanks to Akim Demaille.
5505 2003-03-29 Akim Demaille <akim@epita.fr>
5507 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
5508 that starts a GUI.
5509 From Ilya Zakharevich.
5511 2003-03-29 Akim Demaille <akim@epita.fr>
5513 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
5514 documentation to read is Autoconf's.
5515 Suggested by Paul Eggert.
5517 2003-03-28 Akim Demaille <akim@epita.fr>
5519 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
5520 reading the section "Present But Cannot Be Compiled" when the
5521 header causes problems.
5523 2003-03-28 Akim Demaille <akim@epita.fr>
5525 * tests/torture.at (Configuring subdirectories): Require aclocal
5526 1.4, otherwise the test fails, as it does support configure.ac.
5527 This fixes the "test 40 failed" bug reports.
5529 2003-03-28 Akim Demaille <akim@epita.fr>
5531 * doc/autoconf.texi (C Compiler): `#line' portability.

5600 (Automake): Automake 1.5+ no longer requires special tools to be
5601 present on the developer's host.
5603 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

5617 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
5618 to cope with DOS-style absolute paths, when constructing
5619 ${ac_make}.
5621 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5622 When constructing paths with IFS=:, quote the path. If we're
5623 constructing a DOS-style absolute path, we don't want to split it
5624 on the colon.
5626 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
5627 in description.

5641 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5642 to fix a mismatch between example and discussion.
5644 2003-02-24 Kevin Ryde <user42@zip.com.au>
5646 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5647 format starting with "-".
5649 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5651 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5652 is not portable inside Makefile.
5654 2003-02-20 Akim Demaille <akim@epita.fr>
5656 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5657 compiler says yeah, but preproc says nope, compiler is right.
5658 Conversely, prompt the reader to send a bug report to the
5659 maintainers of the package, not of Autoconf.
5661 2003-02-20 Klee Dienes <kdienes@apple.com>
5663 * bin/autoreconf.in (autoreconf_current_directory): Properly

5674 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5675 innocuous variant befor including <limits.h> or <assert.h>. This
5676 works around a bug reported by Albert Chin: HP-UX 11i
5677 (and earlier versions) have a <limits.h> that declares
5678 gettimeofday and many other functions.
5680 2002-12-03 Paul Eggert <eggert@twinsun.com>
5682 Version 2.57.
5684 * NEWS, configure.ac: Update version.
5686 * doc/fdl.texi: Upgrade to FDL version 1.2.
5688 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5689 nontrivially in main's body, so that f's external declaration is
5690 not optimized away in AIX. This should fix the bug reported by
5691 Martin Frydl in
5692 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5694 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5695 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5696 defined, to support freestanding compilers. This should fix the
5697 bug reported by Momchil Velkov in
5698 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5700 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5701 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

5706 * Makefile.maint (www-gnu): New macro.
5707 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
5708 the location has moved.
5710 2002-12-02 Martin Frydl <martin@systinet.com>
5712 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5713 \(.*\) match is too long and there is something more to be checked.
5714 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
5716 2002-11-15 Akim Demaille <akim@epita.fr>

5725 Require 1.7.1.
5727 2002-11-14 Akim Demaille <akim@epita.fr>
5729 Version 2.55.
5731 * config/config.guess, config/config.sub, config/install-sh:
5732 Update from masters.
5734 2002-11-14 Akim Demaille <akim@epita.fr>
5736 * Makefile.maint: Sync with Bison, i.e.:
5737 (po-check): Scan .l and .y files instead of the
5738 .c and the .h files that they generate. This fixes the bug
5739 reported by Tim Van Holder in:
5740 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5741 Look for N_ as well as for _. Try to avoid matching #define for
5742 N_ and _.
5743 From Paul Eggert.
5745 2002-11-14 Akim Demaille <akim@epita.fr>
5747 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5748 From Paul Eggert and Albert Chin-A-Young.
5750 2002-11-14 Akim Demaille <akim@epita.fr>

5753 From Paul Eggert and Albert Chin-A-Young.
5755 2002-11-14 Kevin Ryde <user42@zip.com.au>
5757 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5758 than assigning in main, to avoid HP cc +O3 optimizing it away.
5760 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5762 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5763 option. Process --recheck after parsing all options. Pass -q
5764 option to configure on --recheck.
5765 (AC_OUTPUT): Pass -q from configure to config.status.
5766 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5767 arguments to record.
5768 * doc/autoconf.texi (config.status Invocation): Document
5769 config.status -q option.
5771 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

5796 Reported by Ezra Peisach.
5798 2002-11-05 Akim Demaille <akim@epita.fr>
5800 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5801 Remove.
5802 We _have_ to stop using the old compatibility scheme that tried to
5803 avoid useless backslashes because Libtool 1.4.3 contains a
5804 AC_DEFINE([error_t], [int],
5805 [Define to a type to use for \`error_t' if it is not
5806 otherwise available.])
5807 We _have_ to quote the single quote and backslashes with \. The
5808 old compatibility scheme saw that ` was backslashed, and therefore
5809 did not quote the single quote. Hence before this patch, Autoconf
5810 was not compatible with Libtool.
5812 2002-11-04 Paul Eggert <eggert@twinsun.com>
5814 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

5821 Version 2.54c.
5823 * Makefile.maint (update, cvs-update, po-update, do-po-update):
5824 New.
5825 * config/texinfo.tex: Update.
5827 2002-11-03 Akim Demaille <akim@epita.fr>
5829 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
5830 from...
5831 (&autoreconf): here.
5832 ($help, $make, &parse_args, &autoreconf_current_directory):
5833 Support -m/--make.
5834 * doc/autoconf.texi (autoreconf Invocation): Adjust.

5850 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
5852 2002-10-31 Akim Demaille <akim@epita.fr>
5854 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5855 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5856 Make variable, not a shell variable.
5857 Suggested by Bruno Haible.
5859 2002-10-31 Akim Demaille <akim@epita.fr>
5861 * bin/autom4te.in (load_configuration): Reject #args out of any
5862 language.
5864 2002-10-31 Akim Demaille <akim@epita.fr>
5866 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
5867 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

5878 Suggested by Tim van Holder.
5880 2002-10-29 Paul Eggert <eggert@twinsun.com>
5882 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
5883 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5884 Problem reported by Bruno Haible.
5886 2002-10-29 Akim Demaille <akim@epita.fr>
5888 * doc/autoconf.texi (Header Templates): Put also in words what the
5889 pictures says to assist free style readers.
5890 (Customizing autom4te): s/--cache=/--cache /.
5892 2002-10-29 Akim Demaille <akim@epita.fr>
5894 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
5895 sys/wait.h.
5896 sparc_address_test returns void.
5897 Use it with an argument, as prototyped.
5898 From Bruno Haible.
5900 2002-10-29 Akim Demaille <akim@epita.fr>

6142 2002-10-22 Akim Demaille <akim@epita.fr>
6144 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

6147 Quote for Perl '' strings, not "".
6148 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6149 strings.
6151 2002-10-22 Akim Demaille <akim@epita.fr>
6153 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

6201 Reported by Alexandre Duret-Lutz.
6203 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6204 to frozen files in @ARGV, as @ARGV must remain being a list of

6206 (&files_to_options): New function.
6207 (&freeze): Use &error.
6208 (&up_to_date): If a file that was included according to the cache
6209 is no longer there, then the output is out dated.

6211 --force is given.
6212 * tests/tools.at (autom4te cache): New.

6220 (&autoreconf): Report the directories we enter *and leave*, so
6221 that error messages can be easily located, and use GNU Make
6222 format, so that Emacs' compile mode understands us.
6223 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6224 if some file was changed instead of `print'.
6225 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6226 (&parse_args): Remove the dead options.
6227 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

6258 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6259 file name to enable parallel executions.
6260 From Sam Varshavchik.
6262 2002-10-08 Akim Demaille <akim@epita.fr>
6264 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6265 aclocal invocation, as Gettext macros might not be visible to
6266 aclocal.
6267 Instead of blindly running autopoint, scan configure.ac (not the
6268 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6269 Reported by Paul D. Smith.
6271 2002-10-08 Paul Eggert <eggert@twinsun.com>
6273 Work around problems found when POSIXLY_CORRECT=1 is set.
6274 None of this seems to have anything to do with POSIX, really,
6275 but it's how Perl getopt works.
6276 * bin/autom4te.in (parse_args): Configure GetOpt with
6277 "permute", too.
6278 * doc/autoconf.texi (Invoking autom4te):
6279 --warning -> --warnings.
6280 * lib/autom4te.in: --warning -> --warnings.

6299 2002-09-28 Akim Demaille <akim@epita.fr>
6301 * tests/torture.at (Configuring subdirectories): Be robust to
6302 users who use config.site to require for a cache: in this case,
6303 the two last configure runs, using two different sets of
6304 arguments, trigger a legitimate error.
6306 2002-09-28 Akim Demaille <akim@epita.fr>

6322 (tm_zone): Move their rules to...
6323 * lib/autoconf/types.m4: here, using AN_ macros.
6324 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6325 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6326 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6327 * lib/autoconf/programs.m4: here.

6339 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6340 (.m4.m4f): Don't pass --prepend-include, since that's done by
6341 tests/autom4te itself.
6342 * lib/autoscan/Makefile.am: Include freeze.mk.
6343 (autoscan.list): New target --this file is no longer a source.
6344 (autoscan.pre): New file.

6351 tracking changes in autoscan.list.
6352 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6354 2002-09-28 Akim Demaille <akim@epita.fr>

6365 * lib/autoscan/identifiers, lib/autoscan/makevars,
6366 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6367 `functions' line is now prefixed with `function:'.
6368 * bin/autoscan.in (&init_tables): Adjust.
6370 2002-09-28 Akim Demaille <akim@epita.fr>
6372 From now on, autoscan files must always map a macro name to a
6373 word: there is no `default' macro for autoscan.
6375 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6376 all.
6377 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6378 explicit.
6380 2002-09-28 Akim Demaille <akim@epita.fr>
6382 * bin/autoscan.in (%c_keywords): Remove.

6416 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6418 2002-09-26 Akim Demaille <akim@epita.fr>
6420 Single suffix rules and seperated dependencies are not portable.
6422 * doc/autoconf.texi (Installation Directory Variables): Update.

6468 Suggested by Guido Draheim.
6470 2002-09-13 Akim Demaille <akim@epita.fr>
6472 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

6476 2002-09-12 Akim Demaille <akim@epita.fr>
6478 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6479 the lists.

6495 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6496 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6497 is obsolescent.
6499 2002-09-11 Akim Demaille <akim@epita.fr>
6501 * doc/autoconf.texi (Questions): Rename as...

6520 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6521 Reported by Ralf Corsepius.

6523 cases.
6525 2002-09-09 Akim Demaille <akim@epita.fr>
6527 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6528 looking for a replacement file.
6529 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6530 directory is relative.
6531 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6532 directory definition.
6533 Reported by Andreas Schwab and Jim Meyering.
6535 2002-09-06 Akim Demaille <akim@epita.fr>
6537 * doc/autoconf.texi (Setting Output Variables): Clarify what
6538 precious variables are.
6539 Suggested by Pontus Skoeld.
6541 2002-09-05 Akim Demaille <akim@epita.fr>
6543 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6544 (ifnames, autoscan, autom4te): Since we don't only depend on
6545 configure.ac variables (such as VERSION etc.), but also on prefix
6546 and so forth, depend on Makefile, not configure.ac.
6547 Reported by Alexandre Duret-Lutz.
6548 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6550 2002-09-05 Kevin Ryde <user42@zip.com.au>
6552 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6553 doesn't seem to be confined to ia64, just say "some versions".
6555 2002-09-04 Akim Demaille <akim@epita.fr>
6557 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6558 Automake 1.6c.
6559 * Makefile.am (maintainer-clean-local): Remove.
6560 (MAINTAINERCLEANFILES): Remove COPYING.
6562 2002-09-03 Paul Eggert <eggert@twinsun.com>
6564 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6565 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6566 Brinkmann.
6568 2002-09-03 Akim Demaille <akim@epita.fr>
6570 * configure.ac: Bump to 2.53d.
6571 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6572 as of today, on Automake's team suggestion.
6574 2002-09-03 Akim Demaille <akim@epita.fr>
6576 Version 2.53c.
6578 2002-09-02 Akim Demaille <akim@epita.fr>
6580 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6581 SITE_MACRO_DIR.
6582 * configure.ac: Disable SITE_MACRO_DIR.
6584 2002-09-02 Jim Meyering <meyering@lucent.com>
6586 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6587 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6588 Also, tweak grammar: s/make sure to/be sure to/.
6590 2002-09-02 Paul Eggert <eggert@twinsun.com>
6592 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6593 directory names are generally preferable to physical names.
6595 2002-09-02 Akim Demaille <akim@epita.fr>
6597 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6598 Reported by Raja R. Harinath.
6599 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6600 * bin/autoupdate.in: Use error instead of die.
6602 2002-09-01 Paul Eggert <eggert@twinsun.com>
6604 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6605 ordinary shell concatenation rather than echo+tr+sed command that
6606 runs afoul of a long-line-related sed bug in Solaris 8.
6608 * bin/autoheader.in (parse_args): --warning -> --warnings.
6610 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6611 stdout, as traditional "ls" does.
6612 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6613 _AC_COMPILER_EXEEXT_O): Likewise.
6614 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6616 * bin/autoconf.as: Add --prepend-include option. This patch was
6617 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6618 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6620 * bin/autoconf.in, configure: Regenerate.
6622 * doc/autoconf.texi (Special Shell Variables): Mention
6623 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6625 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6626 MAILPATH and set PS1, PS2, PS4 to default values, to work
6627 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6628 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6629 the Autoconf documentation specifies; fall back to "unset" only if
6630 this fails. Use a shell for-loop for this rather than an m4 loop,
6631 to shorten the output script.
6633 2002-08-30 Paul Eggert <eggert@twinsun.com>
6635 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6636 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6637 for the CDPATH problem. Document PWD.
6638 (Limitations of Builtins): Document the problem that "cd $foo" and
6639 "ls $foo" may refer to different directories in shells conforming
6640 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6641 example, since the old example is now out of date.
6643 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6644 FOO" and "ls FOO" talk about different directories; this catches
6645 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6646 spaghetti.
6648 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6649 of rolling our own unset.
6650 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6651 in practice we needn't worry about CDPATH if unset doesn't work.
6653 * Makefile.in, aclocal.m4, bin/Makefile.in,
6654 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6655 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6656 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6657 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6658 tests/Makefile.in: Regenerate with Automake 1.6.3.
6660 * config/config.guess, config/config.sub, config/mkinstalldirs:
6661 Update.
6663 * configure: Regenerate with self.
6665 2002-08-30 Kevin Ryde <user42@zip.com.au>
6667 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6668 default output.
6670 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6672 * bin/autom4te.in (Request::load): Correctly test for "do" read
6673 failure.
6675 2002-08-29 Akim Demaille <akim@epita.fr>
6677 * lib/Autom4te/General.pm (&xqx): New.
6678 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6679 hand, which is not portable.
6680 (&error): New.
6681 * bin/autom4te.in: Use them.
6682 Use &error instead of die.
6683 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6684 Adjust.
6686 2002-08-17 Paul Eggert <eggert@twinsun.com>
6688 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6689 default list of compilers to try, since it was long ago superseded
6690 by the ksh fc builtin. Suggested by Steven G. Johnson.
6692 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6694 * doc/autoconf.texi (Invoking autom4te): End the option table,
6695 fixing a bug introduced by the previous patch.
6696 (Limitations of Make): Add a 'target lookup' subentry in the
6697 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6699 2002-07-29 Mark D. Roth <roth@feep.net>
6701 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6702 options and use $AUTOM4TE_PATH.
6703 * doc/autoconf.texi: Remove documentation of autom4te
6704 --include-envvar and --site-macro-subdir options and document
6705 use of $AUTOM4TE_PATH.
6706 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6707 arguments from each language section.
6709 2002-07-29 Paul Eggert <eggert@twinsun.com>
6711 * doc/install.texi: Include copyright symbol in copyright notice.
6713 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6714 Replace with:
6715 (AM_MAKEINFOFLAGS): New macro.
6716 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6717 * Makefile.am (INSTALL): Use the new macros.
6718 Use -o rather than --output, since "missing" does not grok --output.
6720 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6722 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6723 comments do not always work. Never trust the exit status of
6724 `make -k'.
6726 2002-07-24 Kevin Ryde <user42@zip.com.au>
6728 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6729 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6731 2002-07-23 Paul Eggert <eggert@twinsun.com>
6733 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6734 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6735 apparently treats PATH="nonexistent" as if it contained ".".
6736 Bug reported by Stefan `Sec' Zehl.
6738 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6740 * doc/autoconf.texi (Limitations of Make): Mention the special
6741 handling of the obj/ directory by BSD make.

6761 2002-07-18 Akim Demaille <akim@epita.fr>
6763 * config/config.guess, config/config.sub: Update.

6897 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
6899 * bin/autom4te.in ($cache): Don't define using `$me', the name
6900 of the cache should not depend on the name under which autom4te
6901 was installed.
6903 2002-06-07 Akim Demaille <akim@epita.fr>
6905 * tests/tools.at (autoconf: forbidden tokens, basic)

7004 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7005 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7006 This improves on an earlier suggestion by H. Peter Anvin.
7008 2002-05-16 Paul Eggert <eggert@twinsun.com>
7010 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7011 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7012 Both macros now accept an optional source-dir arg.
7013 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7015 * NEWS: Document this.
7016 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7018 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7019 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7020 not for GNU extensions; this undoes part of the 2000-11-03 change,
7021 reverting to 2.13-compatible behavior.
7022 Add new optional argument DIR.
7023 (AC_FUNC_FNMATCH_GNU): New macro.
7025 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7027 2002-05-08 Paul Eggert <eggert@twinsun.com>
7029 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7030 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7031 and it causes a 'test' syntax error if it fails.
7032 Bug reported by Stephen Gildea.
7034 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7035 If prototypes are supported, use them to check this at compile-time,
7036 instead of trying to check it at run-time. If we must do a run-time
7037 check, assume that setvbuf is standard when cross-compiling, as
7038 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7039 Bug reported by Paul D. Smith.
7041 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7042 argument specifying location of getloadavg.c. This removes a
7043 FIXME. This idea was taken from Jim Meyering's implementation in
7044 textutils.
7045 * doc/autoconf.texi (Particular Functions): Document this.
7046 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7047 that's what the code does; this fixes a bug reported by
7048 Paul D. Smith.
7050 2002-05-03 Akim Demaille <akim@epita.fr>
7052 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7053 autopoint instead of gettextize.
7054 ($uses_alocal): Rename as...
7055 ($uses_aclocal): this.
7056 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7057 Suggested by Bruno Haible.
7059 2002-05-03 Akim Demaille <akim@epita.fr>
7061 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7063 2002-04-29 Paul Eggert <eggert@twinsun.com>
7065 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7066 files to be 1 second older; just set them to be the same time.
7067 Also, sleep 1 second after the first aclocal, to work around
7068 problems with sub-second time stamps on the input files.
7070 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7072 * doc/autoconf.texi: Mention "set -e -x" lossage
7073 under node "Limitations of Builtins".
7075 2002-04-29 Akim Demaille <akim@epita.fr>
7077 * doc/install.texi: Better wording for setting variables when
7078 running configure.
7079 From Christian Cornelssen.
7081 2002-04-29 Akim Demaille <akim@epita.fr>
7083 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7084 of lack of $LINENO support, then the test will compare the $LINENO
7085 in testsuite vs. the lineno in the test file. This is wrong, of
7086 course.
7087 Be sure to protect it.
7088 Reported by Patrick Welche.
7090 2002-04-25 Akim Demaille <akim@epita.fr>
7092 * doc/autoconf.texi (Obsolete Macros): Typo.
7093 Reported by Vladimir Volovich.
7095 2002-04-25 Akim Demaille <akim@epita.fr>
7097 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7098 than some of the input files, hence, on the second run of aclocal,
7099 if some of its input are younger, make them older.
7100 Suggested by Paul Eggert.
7102 2002-04-25 Akim Demaille <akim@epita.fr>
7104 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7105 Thanks to Paul Eggert.
7107 2002-04-25 Akim Demaille <akim@epita.fr>
7109 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7110 and ac_subst_vars be sh variables containing the list of
7111 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7112 DEFAULT diversion.
7113 (_AC_INIT_PREPARE): Use them to log them.
7114 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7115 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7116 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7117 _AC_SUBST_FILES and _AC_SUBST_VARS.
7118 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7120 2002-04-24 Akim Demaille <akim@epita.fr>
7122 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7123 autoheader, so that automake does not complain about a missing
7124 config.h.in that was to be created.
7126 2002-04-23 Akim Demaille <akim@epita.fr>
7128 * bin/autoheader.in (parse_args): --warning takes an argument.
7129 Fixes PR/220.
7131 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7133 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7134 and bb.out when cleaning up.
7136 2002-04-22 Akim Demaille <akim@epita.fr>
7138 Version 2.53a.
7140 2002-04-22 Akim Demaille <akim@epita.fr>
7142 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7144 2002-04-22 Akim Demaille <akim@epita.fr>
7146 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7147 comma.
7148 Reported by Gregory Giannoni.
7150 2002-04-22 Akim Demaille <akim@epita.fr>
7152 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7153 Fixes false failures on Darwin.

7159 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7178 Minor spelling and grammar fixes.
7180 * doc/autoconf.texi: Follow the outline suggested in the GNU
7181 Sample Texts sections of the Texinfo 4.2 manual. Most
7182 importantly, this makes sure that the copyright notices appear in
7183 all output formats. You probably need Texinfo 4.2 to generate
7184 the manual now.
7186 Fix some bugs when using "$@" when there might be zero positional
7187 arguments in cases where this matters.

7207 * tests/c.at: We can't have zero arguments, so remove workaround
7208 that is not portable to Zsh.
7210 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7212 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7213 from aclocal.m4 too.
7215 2002-04-12 Akim Demaille <akim@epita.fr>
7217 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7219 2002-04-10 Akim Demaille <akim@epita.fr>
7221 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7222 workaround for ${1+"$@"}.
7223 * doc/autoconf.texi (Shell Substitutions): Explain it.
7224 From Oliver Kiddle and Peter Stephenson.
7226 Have M4sh perform minimal shell sanitizing.
7228 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7229 part into...
7230 (_AS_PREPARE): this new macro.
7231 (AS_PREPARE): New.
7232 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7233 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7235 Adjust Autoconf and Autotest.
7237 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7238 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7239 * lib/autotest/general.m4 (AT_INIT): Likewise.
7240 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7241 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7242 AS_SHELL_SANITIZE.
7244 Use this M4sh to generate Autoconf's shell scripts.
7246 * tests/wrapsh.as: New, precursor of wrapsh.in.
7247 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7248 on Autotest and M4sh.
7249 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7250 (wrapsh.in): New target.
7251 * bin/autoconf.as: New, precursor of autoconf.in.
7252 (autoconf.in): New target.
7254 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7257 with indented comments in rules.
7259 2002-04-09 Andreas Schwab <schwab@suse.de>
7261 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7262 ac_top_builddir when setting ac_abs_top_builddir.
7264 2002-04-06 Kevin Ryde <user42@zip.com.au>
7266 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7267 (Portable Shell): Cross reference to Systemology.
7269 2002-04-05 Akim Demaille <akim@epita.fr>
7271 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7272 directories when descending in a SUBDIRS.
7273 Reported by Ezra Peisach.
7275 2002-04-04 Andreas Schwab <schwab@suse.de>
7277 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7278 contains no literal separators.
7280 2002-04-03 Akim Demaille <akim@epita.fr>
7282 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

7284 Use dnl, not the KILL diversion.
7285 Extracted from...
7286 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7287 (AC_CONFIG_LINKS): here.
7288 Adjust.
7289 Don't use the KILL diversion, as it kills spurious output, which
7290 results in failures being hidden.
7291 Use m4_defn where appropriate.
7292 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7293 after the second argument.
7294 Use m4_defn.
7295 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7296 syntax, as it is provided by M4sugar.
7297 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7299 2002-04-03 Andreas Schwab <schwab@suse.de>
7301 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7302 expanded if $# <= 2.
7304 * bin/autoreconf.in (autoreconf): Run automake after rerunning
7305 aclocal.

7312 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7313 (_AC_COMPILER_OBJEXT): Use them.
7314 Fixes Debian #138666.
7316 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7318 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7320 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7321 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7322 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7323 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7324 (AC_C_CONST): Same.
7325 (AC_C_INLINE): Same.
7326 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
7327 * doc/autoconf.texi, NEWS: Document.
7328 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7329 AC_C_CROSS.

7334 _AS_MKDIR_P_PREPARE.
7336 2002-03-28 Kevin Ryde <user42@zip.com.au>
7338 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7339 to avoid versions of HP C which don't allow that.
7341 2002-03-27 Paul Eggert <eggert@twinsun.com>
7343 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7344 (AS_SHELL_SANITIZE): Invoke it.
7345 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

7355 2002-03-25 Paul Eggert <eggert@twinsun.com>
7357 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7358 as POSIX requires, as it doesn't work with Zsh.
7359 * doc/autoconf.texi (Assignments): Document the problem.
7361 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7363 * doc/autoconf.texi (Limitations of Make): Mention more issue
7364 about VPATH, overriding of macros in sub-makes, and handling of
7365 SHELL.
7367 2002-03-21 Paul Eggert <eggert@twinsun.com>
7369 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7370 problem with here-document buffer boundaries.
7372 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7373 when reinvoking the shell, to work around problems with installers
7374 who put strange things like "cd" commands in their environments.
7376 2002-03-19 Akim Demaille <akim@epita.fr>
7378 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7379 From Aaron Ucko.
7381 2002-03-19 Akim Demaille <akim@epita.fr>

7389 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7390 From Nishio Futoshi.
7392 2002-03-19 Akim Demaille <akim@epita.fr>
7394 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7396 2002-03-18 Paul Eggert <eggert@twinsun.com>
7398 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7399 (Limitations of Usual Tools): Add mkdir section.
7401 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7402 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7403 back on AS_DIRNAME to compute prefixes otherwise; this is
7404 roughly what mkinstalldirs does. That way, we need not have
7405 our own filename disassembler. The old disassembler did not
7406 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7408 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7409 Create at_test_all by a series of assignments,
7410 not by a single assignment of a long string. The latter causes ksh
7411 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7412 presumably because of a buffer overrun.
7414 2002-03-14 Paul Eggert <eggert@twinsun.com>
7416 * lib/autotest/general.m4 (at_times_skip):
7417 Renamed from at_times. Now a boolean.
7418 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7419 says 'times: not found'.
7421 2002-03-14 Akim Demaille <akim@epita.fr>
7423 * bin/autoreconf.in (&study_gettextize): New.
7424 (&autoreconf): Handle newest gettextize.

7435 Add information about stdint.h and inttypes.h from Paul Eggert.
7437 2002-03-13 Akim Demaille <akim@epita.fr>
7439 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7440 -p'.
7441 From Bob Proulx.
7443 2002-03-12 Akim Demaille <akim@epita.fr>
7445 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7446 m4_require.
7448 2002-03-11 Andreas Schwab <schwab@suse.de>
7450 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7451 does not do it if --with-lispdir is given.
7453 2002-03-08 Akim Demaille <akim@epita.fr>
7455 Version 2.53.
7457 2002-03-08 Akim Demaille <akim@epita.fr>

7460 subdirectory should exist.
7462 2002-03-08 Akim Demaille <akim@epita.fr>
7464 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7466 2002-03-08 Akim Demaille <akim@epita.fr>
7468 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7469 aliases the actual variables, and modifications of the former
7470 affect the latter.
7472 2002-03-08 Akim Demaille <akim@epita.fr>
7474 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7475 because of C-c: have m4 output in tmp files, then mv them.
7477 2002-03-08 Akim Demaille <akim@epita.fr>
7479 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

7494 Version 2.52i.
7496 2002-03-04 Akim Demaille <akim@epita.fr>
7498 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.

7504 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7505 parallel builds.
7507 2002-03-04 Akim Demaille <akim@epita.fr>
7509 * doc/autoconf.texi (Transforming Names): Equality between target
7510 and host is irrelevant.
7511 (Specifying Names, Canonicalizing): Remove all references to the
7512 backward compatibility hooks. Rather, collect them all into...
7513 (Hosts and Cross-Compilation): this new section.
7514 * doc/install.texi (System Type): Ditto.
7515 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7516 that `--host' implies cross-compilation.
7518 2002-03-04 Akim Demaille <akim@epita.fr>
7520 * doc/autoconf.texi (Evaluation Macros): New.
7521 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7522 useless.
7523 (_m4_foreach): Define the variant with immediate evaluation so
7524 that it contains exactly the items, not an expression which
7525 evaluation is the current item.
7526 (m4_re_string, m4_re_word): Don't over quote them.
7528 2002-03-04 Akim Demaille <akim@epita.fr>
7530 Instead of having stacking `shift's evaluated at the end, let
7531 `foreach' loops immediately evaluate them.
7533 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7534 $*. This is the n-th time I change my mind, but hopefully this is
7535 the last...
7536 (m4_lquote): New.
7537 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7538 efficient.
7539 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7540 it was only a hack for m4_text_wrap.
7541 (m4_car2): Remove, replaced by...
7542 (m4_cdr): New.
7543 (_m4_foreach): Adjust.
7544 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7545 m4_bpatsubst for clarification.
7547 2002-03-04 Akim Demaille <akim@epita.fr>
7549 * doc/autoconf.texi (Changequote is Evil): New.
7551 2002-03-03 Kevin Ryde <user42@zip.com.au>

7554 on old systems like SunOS.

7562 of messages.
7564 2002-02-28 Akim Demaille <akim@epita.fr>
7566 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
7567 message to be sent.
7569 2002-02-28 Kevin Ryde <user42@zip.com.au>
7571 * doc/autoconf.texi (Function Portability): Add va_copy and va_list.
7573 2002-02-25 Akim Demaille <akim@epita.fr>
7575 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
7576 From Akinori Musha.
7578 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
7580 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
7581 translate \r\n to \n.
7583 2002-02-07 Akim Demaille <akim@epita.fr>
7585 Version 2.52h.
7587 2002-02-07 Akim Demaille <akim@epita.fr>
7589 Fix Autoconf PR/209.
7590 Also reported by Frank Denis.
7592 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
7594 2002-02-07 Akim Demaille <akim@epita.fr>
7596 Fix Autoconf PR/207:
7597 AC_PREFIX_PROGRAM fails with dashed program names
7599 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7600 variable when looking for the prefix program.
7601 Now it also works for shell variables.
7603 2002-02-07 Akim Demaille <akim@epita.fr>
7605 * doc/autoconf.texi (Limitations of Builtins): More about
7606 case/esac.
7608 2002-02-06 Akim Demaille <akim@epita.fr>
7610 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7611 case/esac, some shells don't support it.
7612 Reported by Zack Weinberg.
7613 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7615 2002-02-06 Akim Demaille <akim@epita.fr>
7617 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7618 sure not to introduce newlines in at_groups.
7619 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7621 2002-02-06 Akim Demaille <akim@epita.fr>
7623 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7624 is not available.
7626 2002-02-05 Paul Eggert <eggert@twinsun.com>
7628 * doc/autoconf.texi (Specific Compiler Characteristics):
7629 Describe HP-UX cc bug workaround more accurately.
7630 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7631 not unsigned long.
7632 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7633 cross-compilers, too. This undoes some of the most recent change
7634 to this file.
7636 2002-02-05 Akim Demaille <akim@epita.fr>
7638 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7639 to make sure they are up to date when `check' is run.
7641 2002-02-05 Akim Demaille <akim@epita.fr>
7643 * doc/autoconf.texi (Making testsuite Scripts): Document
7644 package.m4.
7646 2002-02-05 Akim Demaille <akim@epita.fr>
7648 * lib/freeze.mk: New.
7650 2002-02-05 Akim Demaille <akim@epita.fr>
7652 Implement `autom4te --freeze'.
7654 * bin/autom4te.in (&freeze): New.
7655 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7656 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7658 2002-02-05 Akim Demaille <akim@epita.fr>
7660 * bin/autom4te.in (&parse_args): Implement `frozen files are
7661 optional are the sum of the previous files on the command line'.
7662 Also, pass `--reload-state=' on them, so...
7663 (handle_m4): don't.
7664 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7665 (M4sh): Rely on M4sugar.
7666 (Autotest, M4sh, M4sugar): Use frozen files.
7668 2002-01-31 Akim Demaille <akim@epita.fr>
7670 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7671 * doc/autoconf.texi (Initializing configure): Adjust.
7673 2002-01-30 Akim Demaille <akim@epita.fr>
7675 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7676 alphanumeric to `-' instead of `_'.
7678 2002-01-30 Akim Demaille <akim@epita.fr>
7680 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7681 for plain code, the other for cross-compilation code. The latter
7682 is now run with GCC only.
7683 * doc/autoconf.texi (Compilers and Preprocessors): New.
7685 2002-01-30 Akim Demaille <akim@epita.fr>
7687 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7688 values.
7689 * doc/autoconf.texi (Initializing configure): Explain how to
7690 change AC_INIT default values.
7692 2002-01-29 Akim Demaille <akim@epita.fr>
7694 * tests/torture.at (Configuring subdirectories): Use configure.in,
7695 so that aclocal 1.4 works.
7696 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7698 2002-01-28 Akim Demaille <akim@epita.fr>
7700 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7701 needs an argument.
7703 2002-01-28 Akim Demaille <akim@epita.fr>
7705 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7706 AUTOTEST_PATH *after* it was set.
7707 Don't put `.' in the PATH: the user should be precise and `./' if
7708 needed. In addition, given that the test suite does some `cd', if
7709 `.' is in the path, the `tested programs' sections will report
7710 programs found in the test suite's directory, while during the
7711 tests (performed in their own directory), these programs are no
7712 longer visible. In other words, the results is confusing and
7713 useless.
7714 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7716 2002-01-24 Akim Demaille <akim@epita.fr>
7718 Version 2.52g.
7720 2002-01-24 Akim Demaille <akim@epita.fr>
7722 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
7723 * doc/autoconf.texi: Finally add Akim as an author.
7725 2002-01-24 Akim Demaille <akim@epita.fr>
7727 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7728 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7729 Bourne. Use /bin/sh.
7730 From Andreas Buening.
7732 2002-01-24 Akim Demaille <akim@epita.fr>
7734 * config/config.guess, config/config.sub, config/texinfo.tex:
7735 Update from masters.
7737 2002-01-24 Akim Demaille <akim@epita.fr>
7739 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

7743 * config/strip.m4: Remove, to ease sync'ing with any version of
7744 Automake.

7748 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7749 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7750 Reported by Geir Ove Myhr.
7752 2002-01-21 Akim Demaille <akim@epita.fr>
7754 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7756 2002-01-21 Akim Demaille <akim@epita.fr>
7758 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7759 message on invalid options.
7760 * bin/autom4te.in (parse_args): Don't use
7761 Autoconf::General::getopt with non valid options.
7763 2002-01-17 Jim Meyering <meyering@lucent.com>
7765 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7766 $ac_cv_exeext so we don't use an old, invalid, cached value.
7768 2002-01-11 Akim Demaille <akim@epita.fr>
7770 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7771 Meyering.
7772 * doc/autoconf.texi (Function Portability): Document the strnlen
7773 limitation.

7775 * lib/autoscan/functions: Adjust.
7777 2002-01-06 Akim Demaille <akim@epita.fr>
7779 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7780 package.m4, since is really depends upon configure.ac, not
7781 configure.
7782 * doc/autoconf.texi (testsuite Scripts): Adjust.
7783 * tests/Makefile.am (package.m4): New.
7784 EXTRA_DIST it since its a source.
7786 2002-01-06 Akim Demaille <akim@epita.fr>
7788 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7789 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7790 and PACKAGE_BUGREPORT from here...
7791 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7792 arguments.
7793 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7794 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7795 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7796 * tests/tools.at (autoheader): Adjust.
7797 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7799 2002-01-06 Akim Demaille <akim@epita.fr>
7801 * bin/autoscan.in (scan_file): Use `&used'.
7803 2002-01-03 Akim Demaille <akim@epita.fr>
7805 * doc/autoconf.texi (Output): Improved wording regarding use of
7806 AC_OUTPUT.
7807 From Olly Betts.
7809 2001-12-18 Kevin Ryde <user42@zip.com.au>
7811 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7812 sometimes needing writable input.
7814 2001-12-17 Jim Meyering <meyering@lucent.com>
7816 * doc/autoconf.texi (New Macros): Tweak wording.
7818 2001-12-14 Akim Demaille <akim@epita.fr>
7820 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7821 trailing files, don't apply `-rf' to files which might not be
7822 created by configure (core, core.*, and *.core), but just `rm -f'.
7823 Suggested by Jonathan Kamens.
7825 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7827 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7829 2001-12-14 Akim Demaille <akim@epita.fr>
7831 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7833 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7835 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7836 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7837 abs_srcdir, top_srcpath to abs_top_srcdir.
7838 (_AC_OUTPUT_FILES): Adjust.
7839 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7840 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7841 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7843 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
7845 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
7846 C/Fortran linking on HP/UX, by extracting the Fortran library
7847 search path from the LPATH line in the $F77 -v output.
7849 2001-12-12 Kevin Ryde <user42@zip.com.au>
7851 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7852 forbidden file descriptors table.
7854 2001-11-26 Akim Demaille <akim@epita.fr>
7856 * bin/autoscan.in (%c_keywords): Build it at top level.
7857 Map to 1 in order to simplify its uses.
7859 2001-11-26 Akim Demaille <akim@epita.fr>
7861 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7862 Remove $filepath, useless.
7863 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7864 variables, they are really part of the tokens.
7865 Split the input line on spaces and then look for tokens.
7866 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7867 because of `lex$U.$(OBJEXT)'.
7868 (&scan_files): Use "@list" instead of join.
7869 * doc/Makefile.am (CLEANFILES): Add *.fns.
7871 2001-11-26 Akim Demaille <akim@epita.fr>
7873 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
7874 Remove, replaced by...
7875 * tests/wrappl.in: Be common for all the Perl executables.
7876 In particular autoscan and autoheader want -I.
7877 * configure.ac: Adjust.
7878 * lib/autoscan/headers: errno.h is portable.
7880 2001-11-26 Akim Demaille <akim@epita.fr>
7882 * bin/autoscan.in (used): New.
7883 Use it.
7885 2001-11-26 Akim Demaille <akim@epita.fr>
7887 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7888 directives.
7889 (&scan_sh_file): Remove a duplicate pattern.
7890 (&check_configure_ac): Use long options.

7896 Before, having a line containing the opening of a multi line
7897 comment made the whole line be ignored.
7899 2001-11-26 Akim Demaille <akim@epita.fr>
7901 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7902 (testsuite Scripts): Be one of its subsection.
7903 (Autotest Logs): New.
7905 2001-11-26 Akim Demaille <akim@epita.fr>
7907 Test groups are now run two directories deeper.
7909 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7910 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7911 at_top_builddir.
7912 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7913 top_srcdir, builddir and top_builddir.
7914 Use `at_*dir' relatively to the directory containing the
7915 suite, use `*dir' when relatively to the current group dir.
7917 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7919 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7920 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7921 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7922 spelling errors.
7924 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7926 * doc/autoconf.texi (Using System Type): Add an example of `case
7927 $host' usage so people quit using `case $target' everywhere.
7929 2001-11-22 Akim Demaille <akim@epita.fr>
7931 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7932 spotted by Jim Meyering.
7934 2001-11-16 Paul Eggert <eggert@twinsun.com>
7936 This patch implements a `long double' suggestion by Oliver Kiddle.
7938 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7939 static, to catch errors if the value isn't known at compile-time
7940 and the compiler supports dynamic arrays. Change its name from
7941 `_array_' to `test_array' to avoid potential name clashes.
7942 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7943 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7944 better than double. Catch a bug in GCC 2.95.2 x86.
7945 * doc/autoconf.texi (C Compiler): Document the above.
7946 * NEWS: Likewise.
7948 2001-11-13 Akim Demaille <akim@epita.fr>
7950 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7951 hand.
7952 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7954 2001-11-13 Akim Demaille <akim@epita.fr>
7956 * lib/autotest/general.m4 (AT_INIT): After having run the test
7957 group, go back to the initial directory, not to at_suite_dir.
7959 2001-11-13 Akim Demaille <akim@epita.fr>
7961 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7962 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7963 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7964 option.
7965 (AT_CHECK_CONFIGURE): Use absolute paths.
7966 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7967 The problem is still the old one: there is no means in M4 (that I
7968 know about) to create a defining macro, because there is no means
7969 to create `$1' etc., therefore, the defining macro ``swallows''
7970 all the arguments meant to the defined macro.
7972 2001-11-13 Akim Demaille <akim@epita.fr>
7974 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7975 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7976 configure.ac.
7977 * tests/aclocal.m4: Remove, as it is no longer used.
7979 2001-11-13 Akim Demaille <akim@epita.fr>
7981 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7982 variable names when referring to a single test group, or to
7983 `suite' when referring to the whole test suite.
7984 `at_last_test' is removed: m4 compute at_format itself.
7985 (at_stdout, at_stder1, at_stderr): New variables.
7986 (AT_CHECK): Use them.
7988 2001-11-13 Akim Demaille <akim@epita.fr>
7990 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7991 in PATH.
7992 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7993 Do it as soon as a test fails, don't wait till the end of the test
7994 suite.
7995 Don't remove $as_me.[0-9]*, since these files no longer exist.
7997 2001-11-13 Akim Demaille <akim@epita.fr>
7999 * tests/tools.at: Use absolute paths, since we are no longer run
8000 in place.
8002 2001-11-13 Akim Demaille <akim@epita.fr>
8004 Now that tests are running in their own private dir, there is no
8005 need to list the files to remove at the end of tests groups.
8007 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8008 (AT_data_files, at_data_files): Remove.
8009 (AT_CLEANUP, AT_DATA): Simplify.
8010 (AT_INIT): Adjust.
8011 Remove the group dir if !debug && !failed.
8012 * tests/atspecific.m4: Adjust.
8014 2001-11-13 Akim Demaille <akim@epita.fr>
8016 Start a new layout for Autotest: `testsuite' creates
8017 `testsuite.dir' in which the at-check-line etc. files are to be
8018 found, and `testsuite.dir/003' where the test group 3 is run.
8020 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8021 at_check_line_file, at_format, at_test_normalized, at_group_dir
8022 are new variables.
8023 Create the directories.
8024 Use absolute paths for at- files.
8025 (AT_CHECK): Adjust.
8027 2001-11-11 Michael Matz <matz@kde.org>
8029 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8030 (m4_car2): New.
8031 (m4_car): Properly quote arguments.
8033 2001-11-13 Akim Demaille <akim@epita.fr>
8035 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8036 with stricter rules on LIBOBJS.
8038 2001-11-12 Paul Eggert <eggert@twinsun.com>
8040 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8041 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8042 __PROTOTYPES too.
8044 2001-11-12 Akim Demaille <akim@epita.fr>
8046 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8048 2001-11-12 Akim Demaille <akim@epita.fr>
8050 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8051 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8052 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8053 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8054 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8055 specify to what the macro should be defined (typically to 1).
8057 2001-11-12 Akim Demaille <akim@epita.fr>
8059 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8060 From Jim Meyering.
8062 2001-11-12 Akim Demaille <akim@epita.fr>
8064 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8065 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8066 definition used by Automake where LEX is +/- "${missing} lex" and
8067 `missing' itself contains variables.
8069 2001-11-12 Akim Demaille <akim@epita.fr>
8071 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8072 Now that M4sh pushes BODY, the comments were output at the end of
8073 the test suites.
8075 2001-11-08 Akim Demaille <akim@epita.fr>
8077 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8078 that we can trace macros from aclocal.m4.
8079 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8080 obsoleted, and redirect to the former anyway.
8081 Reported by Ralf Corsepius.
8083 2001-11-08 Akim Demaille <akim@epita.fr>
8085 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8086 processed only if present.
8087 * tests/torture.at (Configuring subdirectories): Use autoreconf
8088 instead of successive calls to autoconf.
8089 Add a nonexistent subdirectory to exercise the patch above.
8090 Reported by Ralf Corsepius.
8092 2001-11-08 Kevin Ryde <user42@zip.com.au>
8094 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8095 doesn't accept .S files.
8097 2001-11-07 Akim Demaille <akim@epita.fr>
8099 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8100 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8101 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8102 * bin/autom4te.in (warn_forbidden): New.
8103 (handle_output): Use it.
8104 Read m4_pattern_forbid with messages.
8106 2001-11-05 Akim Demaille <akim@epita.fr>
8108 * bin/autom4te.in (--normalize): Remove.
8109 * lib/autom4te.in: Adjust.
8111 2001-11-05 Akim Demaille <akim@epita.fr>
8113 * tests/Makefile.am (testsuite): Rename this target as...
8114 ($(TESTSUITE)): this.
8115 From Nicolas Joly.
8117 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8119 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8120 the --prefix option, also remove it's argument.
8122 2001-11-05 Akim Demaille <akim@epita.fr>
8124 * doc/autoconf.texi (testsuite Invocation): Update.
8125 (Writing testsuite.at): Update.
8127 2001-11-03 Akim Demaille <akim@epita.fr>
8129 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8131 2001-11-03 Akim Demaille <akim@epita.fr>
8133 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8134 (&file_name_is_absolute): New, wrappers around routines from
8135 File::Spec.
8136 Use and export them.
8137 (&find_configure_ac): Optionally take a directory where to look at.
8138 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8139 the arguments.
8140 Default @ARGV to `.', not find_configure_ac.
8141 (&autoreconf): Argument is a directory.
8142 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8143 * doc/autoconf.texi (autoreconf Invocation): Update.
8145 2001-11-03 Akim Demaille <akim@epita.fr>
8147 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8148 (@export_forward_subs): New.
8149 Add basename, dirname, and fileparse.
8150 (@EXPORT): Adjust.
8151 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8152 Don't look for aclocal flags if we already know aclocal is not
8153 used.
8154 Move aclocal.m4t only if it exists.
8155 Reported by Ezra Peisach.
8157 2001-11-03 Akim Demaille <akim@epita.fr>
8159 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8160 passed on command line, defaulting to ./configure.ac if present.
8161 (&maybe_autoreconf, File::Find): Remove, unused.
8162 (&autoreconf): If autoconf is not used, don't try to trace.
8164 2001-11-02 Akim Demaille <akim@epita.fr>
8166 * configure.ac: Bump to 2.52g.
8168 2001-11-02 Akim Demaille <akim@epita.fr>
8170 Version 2.52f.
8172 2001-11-02 Akim Demaille <akim@epita.fr>
8174 * config/config.guess, config/config.sub, doc/standards.texi:
8175 * config/lispdir.m4: Update from masters.
8176 * configure.ac: Bump to 2.52f.
8178 2001-11-02 Akim Demaille <akim@epita.fr>
8180 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8181 Don't run aclocal when aclocal.m4 is not from aclocal.
8182 From Ezra Peisach.
8183 Don't run libtoolize and gettextize if --install is not given.
8185 2001-11-01 Paul Eggert <eggert@twinsun.com>
8187 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8188 be invoked before _AS_LINENO_PREPARE.
8189 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8190 than character ranges.
8192 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8193 invoking AS_BASENAME. Set the locale variables to 'C' if
8194 possible, as POSIX requires this to get the traditional
8195 behavior.
8196 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8198 2001-10-31 Paul Eggert <eggert@twinsun.com>
8200 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8201 with {}, as that triggers a bug in Bash 2.05.
8203 (_AS_LINENO_PREPARE): Use Sed rather than
8204 Awk. Fix the sed prepass to work even if there are multiple
8205 instances of $LINENO on the same line. Do not substitute for
8206 other variables like $LINENOT. Do not check file dates; such a
8207 check is unreliable on sufficiently fast machines, and removing
8208 the check makes the code simpler and more reliable. Check for
8209 output and chmod failures.
8211 * doc/autoconf.texi (Special Shell Variables): Document
8212 the above.
8214 2001-10-31 Akim Demaille <akim@epita.fr>
8216 * tests/Makefile.am (atconfig): Remove this target, Automake
8217 handles it now.
8219 2001-10-31 Akim Demaille <akim@epita.fr>
8221 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8222 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8223 provided, while it is optional.
8224 * configure.ac: Adjust.
8226 2001-10-26 Paul Eggert <eggert@twinsun.com>
8228 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8229 lib/Autom4te/Struct.pm:
8230 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8231 with 5.005_02.
8233 * doc/autoconf.texi (Special Shell Variables): Document some
8234 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8236 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8237 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8238 eval $LINENO is not portable in practice.
8240 2001-10-24 Akim Demaille <akim@epita.fr>
8242 * lib/Autom4te/General.pm (backname): New.
8244 2001-10-24 Akim Demaille <akim@epita.fr>
8246 * m4/: Remove, merged into...
8247 * config/: here.
8249 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8251 * doc/autoconf.texi (Shellology): Mention the problems with bash
8252 2.05's use of ANSI quoting in its `set' builtin.
8254 2001-10-22 Paul Eggert <eggert@twinsun.com>
8256 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8257 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8258 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8259 POSIX decided to standardize on the int flavor of strerror_r.
8260 Always do char* test, as there's no reason not to.
8261 Assign to a char* var, to catch strerror_r that returns int*.
8263 * doc/autoconf.texi (Particular Functions):
8264 Document the above changes. Also, document the fact that
8265 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8267 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8269 2001-10-20 Akim Demaille <akim@epita.fr>
8271 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8272 the executable was missing from the log.
8274 2001-10-20 Akim Demaille <akim@epita.fr>
8276 * lib/Autom4te/General.pm (&update_file): If destination is
8277 unchanged, remove the source.
8278 (&up_to_date_p): Don't be verbose, be debug.
8279 * bin/autoreconf.in: No longer support --m4dir.
8280 (&autoreconf): Display the full path of the configure.ac we are
8281 studying.
8282 Trace it only once.
8283 Be sure to honor --force with gettextize.
8284 Always run aclocal.
8285 * doc/autoconf.texi: Adjust.
8287 2001-10-20 Akim Demaille <akim@epita.fr>
8289 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8290 Remove, dead.
8291 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8292 `intl' is already present, as it refuses unless --force.
8293 (&parse_args): Use -I, --include instead of the old Autoconf
8294 options.
8295 ($localdir, $autoconf_dir): Remove.
8296 (@include): New.
8297 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8299 2001-10-19 Jens Petersen <petersen@redhat.com>
8301 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

8306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
8307 file in @configure_input@.
8308 Don't mention `automatically' in addition to `generated'.
8309 * tests/torture.at (#define header templates): Adjust.
8311 2001-10-19 Akim Demaille <akim@epita.fr>
8313 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
8314 comment, explain how to install automatic mode selection.
8315 From Russ Allbery.
8317 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8319 * bin/autoreconf.in (autoreconf): Display the path to the
8320 configure.ac being studied.
8322 2001-10-18 Paul Eggert <eggert@twinsun.com>
8324 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8325 long, to work around a bug in the HP C compiler version HP92453-01
8326 B.11.11.23709.GP.
8328 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8329 (AS_BASENAME_EXPR): New macro.
8330 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8331 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8332 and fall back on 'sed' only if the other two fail. This makes
8333 AS_BASENAME act more like AS_DIRNAME.
8334 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8335 contains white space.
8336 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8337 Use AS_DIRNAME, since I think it's now DOS-friendly.
8338 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8339 Allow "dirname //FOO" to return either / or //, as POSIX allows
8340 either behavior.
8342 2001-10-10 Akim Demaille <akim@epita.fr>
8344 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8345 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8346 From Eric Sharkey.

8350 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

8395 * bin/autoreconf.in: Rewrite in Perl.
8396 * configure.ac: Adjust.

8451 (autotest-mode): Adjust.
8452 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

8475 * doc/autoconf.texi (config.status Invocation):
8476 CONFIG_SHELL defaults to a shell that supports LINENO if available.
8478 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
8479 shell does not support LINENO, and if CONFIG_SHELL is unset or
8480 empty, and if we can find a shell that does support LINENO,
8481 then set CONFIG_SHELL to that shell and then re-execute
8482 ourselves with CONFIG_SHELL.
8484 2001-10-05 Paul Eggert <eggert@twinsun.com>
8486 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8487 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8488 build of $(TESTSUITE).
8490 2001-10-05 Akim Demaille <akim@epita.fr>
8492 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8500 PATH_SEPARATOR before using it.
8501 Fix the absolute path case/esac pattern.
8502 Provide $0 as fallback for as_myself.
8503 Reported by Raja R Harinath.
8505 2001-10-05 Akim Demaille <akim@epita.fr>

8510 2001-10-05 Akim Demaille <akim@epita.fr>
8512 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
8513 (AS_SHELL_SANITIZE): here. Use it.
8514 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
8515 From Paul Eggert.
8517 2001-10-04 Akim Demaille <akim@epita.fr>
8519 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
8520 combination of Awk and sed to replace $LINENO.
8522 2001-10-02 Paul Eggert <eggert@twinsun.com>
8524 * doc/autoconf.texi (Limitations of Builtins): You can't use
8525 "source"; it's not portable. Remove confusing and
8526 somewhat-incorrect example involving "." and "/".
8528 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
8529 compatibility with POSIX shells.
8531 2001-10-02 Akim Demaille <akim@epita.fr>
8533 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
8534 instead of exec'ing to preserve $0 and $@.
8536 2001-10-01 Akim Demaille <akim@epita.fr>
8538 * tests/testsuite (AT_INIT) <at_pass_list>: New.

8555 2001-09-30 Paul Eggert <eggert@twinsun.com>
8557 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
8558 Don't use nested parenthesization. This patch was originally
8559 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
8560 but somehow it didn't get incorporated then.
8561 * doc/autoconf.texi (Limitations of Usual Tools):
8562 Clarify remark about sed and nested parenthesization.
8564 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
8565 Report an error if the size cannot be determined even though
8566 the type exists.
8567 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8568 Check for `expr' arithmetic overflow, and for compilation failure,
8569 and invoke a new argument $4 if either is discovered.
8570 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
8571 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
8573 2001-09-28 Akim Demaille <akim@epita.fr>
8575 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

8587 2001-09-27 Akim Demaille <akim@epita.fr>
8589 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
8590 generates too many bug reports.

8593 status when executing the ACTION-IF-FALSE.
8594 * tests/base.at (AC_TRY_*): Rename as...

8599 (Broken/missing compilers, AC_PROG_CPP with warnings)
8600 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
8601 * tests/c.at (Extensions, C keywords)
8602 (Broken/missing compilers, AC_PROG_CPP with warnings)
8603 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
8604 (AC_PROG_CPP requires AC_PROG_CC): here and...
8605 * tests/fortran.at (GNU Fortran 77): there.
8606 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8607 AC_TRY_RUN is about compilation, not shell commands.
8608 (Test Programs): AC_TRY_RUN works as used to be advertised.
8610 2001-09-27 Akim Demaille <akim@epita.fr>
8612 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8613 Raja R Harinath:
8614 Be sure to detect when $LINENO always returns the same value.
8615 Look for the original script, basename($0) is certainly not
8616 enough.
8617 Pass the CLI arguments to `$as_me.lineno'.
8619 2001-09-25 Akim Demaille <akim@epita.fr>
8621 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
8622 Be sure the close and reopen the LOG fd before and after using tee
8623 to extend the log.

8626 2001-09-23 Akim Demaille <akim@epita.fr>
8628 * bin/autom4te.in (parse_args): There can be several invocations
8629 of --language now.
8631 2001-09-23 Akim Demaille <akim@epita.fr>
8633 * doc/autoconf.texi (Top): Wrap in @ifnottex.
8635 2001-09-23 Akim Demaille <akim@epita.fr>
8637 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
8638 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
8639 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
8640 builddir, buildpath, top_builddir, and top_buildpath.
8641 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
8642 the current directory.
8643 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
8644 variables *before* changing the current directory.
8645 Skip nonexistent dirs.
8646 * doc/autoconf.texi (Preset Output Variables): Document these
8647 variables.
8649 * lib/autotest/general.m4: Do not reset AT_victims.
8650 Don't compute at_srcdir nor at_top_srcdir.
8652 * tests/tools.at: Hence use top_srcdir.
8654 * tests/Makefile.am, tests/autoconf, tests/autoheader,
8655 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
8656 Remove.
8657 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,

8659 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
8660 * configure.ac: Build the position independent wrappers.
8662 * man/Makefile.am: Now that test wrappers are position
8663 independent, use them and drop dark envvar magic.
8665 2001-09-23 Akim Demaille <akim@epita.fr>
8667 * doc/autoconf.texi (Common Shell Constructs): Rename as...
8668 (Programming in M4sh): this.

8696 (Autoconf): Adjust.
8698 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
8700 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
8701 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
8702 to match current versions from CVS Automake.
8704 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>
8706 * doc/autoconf.texi (Special Shell Variables): Add pdksh output
8707 for $LINENO.
8709 2001-09-22 Akim Demaille <akim@epita.fr>
8711 * lib/autoconf/autotest.m4: Create `package.m4'.
8712 * tests/Makefile.am (package.m4): Remove.
8714 2001-09-22 Akim Demaille <akim@epita.fr>
8716 Rely on `$LINENO' when possible instead of `__oline__'.
8718 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
8719 `$LINENO' support replacement when not supported.
8720 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
8721 them explicitly to be sure they are not output before this section
8722 (via m4_require). Cosmetic only.
8723 * lib/autoconf/c.m4, lib/autoconf/general.m4,
8724 * lib/autoconf/programs.m4: Replace all the occurrences of
8725 `__oline__' with `$LINENO'.
8726 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
8728 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
8730 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
8731 character (u: -> ue) in a code comment.
8732 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
8733 it works.
8735 2001-09-21 Akim Demaille <akim@epita.fr>
8737 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
8738 Suggested by Jim Meyering.
8740 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8742 * lib/autoconf/programs.m4: Use extensions listed in
8743 $ac_executable_extensions when looking for programs.
8745 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8747 * lib/autoconf/general.m4: Fix a small Englisho.

8750 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
8752 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8754 * doc/autoconf.texi (File System Conventions): Clarify the use of
8755 PATH_SEPARATOR.
8756 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
8757 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8758 be used instead of ':'.
8759 * lib/autotest/general.m4: Replace occurrences of ':' in
8760 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
8762 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8764 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
8765 arguments. Fixed a typo.
8767 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8769 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8770 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8772 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8774 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
8775 * bin/autoupdate.in: Ditto.
8776 * bin/autoheader.in: Reworded a few comments.
8777 * bin/autoconf.in: Reworded help text for a few options.

8781 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8783 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8784 already have $file). Set output files to binary mode (helps avoid
8785 CR issues on DOSish systems).
8787 2001-09-19 Akim Demaille <akim@epita.fr>
8789 * lib/autotest/general.m4: Englishoes.
8790 From Tim Van Holder and Alexey Mahotkin.
8792 2001-09-18 Paul Eggert <eggert@twinsun.com>
8794 * doc/autoconf.texi (Common Shell Constructs): New node,
8795 documenting AS_DIRNAME.
8796 (Limitations of Usual Tools): Refer to it when discussing dirname.
8797 Also, update discussion of POSIX standard to reflect latest draft.
8799 * lib/autoconf/c.m4:
8800 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8802 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8803 Do not pass a first argument with leading '-'
8804 to expr, by parenthesizing initial integers that might be negative.
8806 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8807 now merely checks whether it is an error to pass an argument
8808 to getpgrp.
8810 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8811 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8812 whether it is a (compile-time) error to pass an argument to
8813 getpgrp. This simpler test supports the revised documentation,
8814 and is all that AC_FUNC_GETPGRP's users really need.
8816 2001-09-18 Akim Demaille <akim@epita.fr>
8818 * doc/autoconf.texi (Limitations of Make) <$<>: New.
8820 2001-09-18 Akim Demaille <akim@epita.fr>

8826 2001-09-18 Paul Wagland <paul@wagland.net>
8828 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8829 correctly.
8830 Add test for AS_BASENAME.
8831 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8832 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8833 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8834 * tests/base.at: Fixed the expected responses. The old ones were
8835 one line out...
8836 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8837 the documentation claims it should (and how it behaved in 2.13).
8839 2001-09-18 Akim Demaille <akim@epita.fr>
8841 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8842 the AC_CONFIG_COMMANDS invocation.
8843 This also solves the name clash problems.
8844 Don't set the package's ID.
8845 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8846 No longer to be shipped.
8847 (version.in): Remove.
8848 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8849 * lib/autoconf/status.m4: Adjust.
8850 Use `m4_PACKAGE_STRING'.
8851 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8852 the only optional argument is the name of the test suite.
8853 Expect `package.m4' to define the package signature.
8854 * lib/autom4te.in (Autotest): Add `package.m4?'.
8855 * tests/Makefile.am (package.m4): New.
8856 * tests/suite.at: ifnames is a victim.
8858 2001-09-18 Akim Demaille <akim@epita.fr>
8860 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8861 AC_LIBSOURCE, AC_CONFIG_FILES.
8862 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8863 program version string doesn't match the package's.
8864 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8865 after `(cached)'.
8867 2001-09-17 Paul Eggert <eggert@twinsun.com>
8869 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8870 Allow expression to return any value that can fit into unsigned long
8871 (not int, as before). Check for output errors.
8873 2001-09-17 Bruno Haible <haible@ilog.fr>
8875 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8876 Always include <stdio.h> and <stdlib.h>. Evaluate
8877 the expression in an extra function before these includes. Call
8878 fprintf "%d" only after ensuring the argument is of type 'int'.
8879 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8881 2001-09-17 Paul Eggert <eggert@twinsun.com>
8883 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8884 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8885 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8886 when they don't exist.
8888 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8889 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8890 need it.
8892 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8893 version with the version used by fileutils 4.1, except use
8894 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8895 we don't need it.
8897 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8899 2001-09-13 Akim Demaille <akim@epita.fr>
8901 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8902 _first_.
8903 Reported by Gerrit P. Haase.
8905 2001-09-13 Akim Demaille <akim@epita.fr>
8907 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
8908 m4_defn'ing is valid.
8910 2001-09-13 Akim Demaille <akim@epita.fr>
8912 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
8913 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
8914 Use it.
8916 2001-09-13 Akim Demaille <akim@epita.fr>
8918 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
8919 m4_match.
8920 (m4_re_escape): New.
8921 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
8922 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
8923 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
8924 Likewise.
8925 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
8926 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
8927 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
8928 AT_tests_all for consistency.
8929 Set at_victims.
8930 (AT_VICTIMS): Similar to AT_KEYWORDS.
8931 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
8933 2001-09-13 Akim Demaille <akim@epita.fr>
8935 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8937 2001-09-13 Akim Demaille <akim@epita.fr>
8939 * lib/autotest/general.m4 (AT_INIT): Create and remove
8940 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8941 test suites can cohabit.
8943 2001-09-13 Akim Demaille <akim@epita.fr>

9051 2001-09-05 Akim Demaille <akim@epita.fr>
9053 Be ready to handle filenames as stupid as `dnl.at', for if even
9054 the maintainer is dumb enough to do that...
9056 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9057 excellence in M4 quotation: consider `__file__' is active.
9059 And BTW, when invoking m4, pass the --include in the right order:
9060 the wrong one.
9062 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9063 4m.

9090 New, extracted from main.
9091 Use IO::File wherever possible.
9092 (input.m4): Be constant, use -I instead of hard coding $tmp.
9093 Therefore be a quoted heredoc.
9094 Don't invoke `_au_disable', since ac was not loaded, but just
9095 `unm4.m4'.
9097 2001-08-31 Akim Demaille <akim@epita.fr>
9099 Version 2.52d.

9122 2001-08-31 Akim Demaille <akim@epita.fr>
9124 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9125 (testsuite Scripts): There is no such thing as `atconfig.in'.
9126 And actually one diagram is missing: test suite runtime.
9128 2001-08-31 Akim Demaille <akim@epita.fr>
9130 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9131 inverse order.
9133 2001-08-31 Akim Demaille <akim@epita.fr>
9135 * bin/autoupdate.in (@include): `installcheck' revealed the path
9136 to m4sugar was lacking!
9138 2001-08-31 Akim Demaille <akim@epita.fr>
9140 * man/Makefile.am (.x.1): We really have to pass
9141 autom4te_perllibdir.
9143 2001-08-31 Akim Demaille <akim@epita.fr>
9145 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

9147 run is stupid.
9149 2001-08-31 Akim Demaille <akim@epita.fr>
9151 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9152 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9153 Use directly autom4te, not autoconf.

9177 `print $out' doesn't print `$_' but `$out'.
9178 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9179 (autoheader): Pass --force since the test suite goes too fast for
9180 the time stamps.
9181 Adjust to the new autoheader messages.
9183 2001-08-31 Akim Demaille <akim@epita.fr>
9185 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

9194 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9195 Drop AC_MACRODIR dead for real.
9196 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9197 `autoheader: `config.hin' is created'.
9198 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9200 2001-08-31 Akim Demaille <akim@epita.fr>
9202 * bin/autoheader.in: Rewrite in Perl.

9205 2001-08-31 Akim Demaille <akim@epita.fr>

9208 Map --localdir, --autoconf-dir onto it.
9209 Forward autom4te's options instead of interpreting them.
9210 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9211 There is no such envvar since the inception of autom4te.cfg.
9212 * bin/autom4te.in (&parse_args): Uniquify `@include'.

9217 2001-08-31 Akim Demaille <akim@epita.fr>

9220 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9221 optionally `FILE'.
9222 Use -e, not -f, since /dev/null for instance is OK.
9223 (&parse_args): Adjust.
9224 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9226 2001-08-31 Akim Demaille <akim@epita.fr>

9229 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9230 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9231 installed peer executables, only PATH is allowed to resolve it.
9232 Pass `autoconf_dir' via options, not via invisible envvars.
9233 * lib/Autom4te/General.pm (&find_peer): Remove.
9234 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9235 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9236 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9237 find the executables for it.
9238 * tests/Makefile.am: Major cleanup. Too lazy to document...
9239 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9240 We only need PERL.
9241 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9242 indeed related to running the test suite, while passing
9243 --autoconf-dir and others is related to running non installed
9244 Autoconf executables. So don't do that, leave it to...
9245 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9246 * tests/autoscan: New.
9247 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9248 refer to library files: rely on --language.

9264 Suggested by Paul Eggert.
9266 2001-08-29 Akim Demaille <akim@epita.fr>
9268 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9269 download in a tmp dir.
9271 2001-08-29 Akim Demaille <akim@epita.fr>
9273 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

9296 (at-devnull): Rename as...
9297 (AT-devnull): this.
9298 (--clean): Remove AT-* files too.

9419 2001-08-27 Akim Demaille <akim@epita.fr>
9421 Automake 1.5.
9423 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
9424 (AMTAR): Help automake define it.
9425 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
9426 needed, 1.5 can have a macro and a target with the same name.
9427 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
9428 * m4/strip.m4: New.

9443 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9444 the name of the directory they're in, instead of the filename,
9445 since version.m4 is now in m4sugar, but m4_acversion must not be
9446 classified as an Autoconf macro.
9447 ($input_m4): Don't qualify the path to m4sugar.
9448 Rather, pass autoconf_dir to m4.
9449 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

9467 for config.status'.
9468 Open the log as soon as possible.
9469 Use the same log introduction as configure's.

9491 * lib/autoconf/programs.m4: here.
9492 (_AC_DECL_YYTEXT): Rename as...

9527 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile

9533 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9534 * NEWS, README, README-alpha, TODO, tests/README: This package is
9535 `Autoconf', not `autoconf' (the executable).
9537 2001-08-20 Akim Demaille <akim@epita.fr>
9539 Info readers seem to need `Index' in the index node title :(
9541 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9542 simplified index node names.

9586 2001-08-20 Akim Demaille <akim@epita.fr>
9588 Huh!?!?! There are still some user EOF tags used, which prevents
9589 their use in AC_CONFIG_COMMANDS for instance...
9591 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
9592 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

9653 2001-08-17 Akim Demaille <akim@epita.fr>
9655 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9656 `$0.log' as for projects where testsuite is in src, we'd have
9657 testsuite.log created in src.
9659 2001-08-17 Akim Demaille <akim@epita.fr>
9661 * bin/autom4te.in (&parse_args): Recognize --normalize.

9671 2001-08-17 Akim Demaille <akim@epita.fr>
9673 * doc/autoconf.texi: Work around Texinfo buglets.
9674 (Transformation Rules): One example is enough, users are expected
9675 to have their brains on. And BTW, use DESTDIR.
9676 (dvar): New macro. Use it.
9678 2001-08-17 Akim Demaille <akim@epita.fr>
9680 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
9681 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when

9687 * bin/autoconf.in: Use it.

9697 start, not at end.
9699 2001-08-15 Akim Demaille <akim@epita.fr>

9713 * doc/install.texi: Use @command.
9714 (Environment Variables): Rename as...
9715 (Defining Variables): this.
9717 2001-08-15 Akim Demaille <akim@epita.fr>
9719 * doc/autoconf.texi (Function Portability): sprintf's return
9720 value.
9721 From Kevin Ryde.
9723 2001-08-15 Akim Demaille <akim@epita.fr>
9725 * Makefile.maint (CVS): New.
9726 (local-check): Run changelog-check. last.
9727 (alpha): Don't depend upon local-check, since...
9728 (cvs-dist): depends upon it.
9730 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9732 * tests/Makefile.am: Use a clean-local rule to remove
9733 autom4te.cache (it's a directory, not a file.
9734 * Makefile.am: Ditto (but maintainer-clean-local).
9736 2001-08-15 Akim Demaille <akim@epita.fr>
9738 * bin/autom4te.in (@m4_warning): New.
9739 (&handle_m4): Use it.
9740 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9741 warnings are issued at each run.
9742 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9743 is in the src tree.
9745 2001-08-15 Akim Demaille <akim@epita.fr>
9747 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9748 don't waste time running `autoupdate --version' works.
9749 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9751 2001-08-13 Akim Demaille <akim@epita.fr>

9804 * tests/mktests.sh: Update year in copyright notice.
9806 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9808 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9810 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9812 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9813 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9814 * doc/autoconf.texi (C Compiler Characteristics): Update
9815 documentation for AC_C_BIGENDIAN.
9817 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9819 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9820 magic values from an object file when cross-compiling.
9821 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9823 2001-08-10 Akim Demaille <akim@epita.fr>
9825 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9826 effects.
9827 Suggested by Russ Allbery.
9829 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9831 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9832 current $prefix to the sub-configures.
9834 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9836 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9837 extension (needed on BeOS). Reported by Guido van Rossum.
9839 2001-08-09 Akim Demaille <akim@epita.fr>
9841 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9843 2001-08-07 Akim Demaille <akim@epita.fr>
9845 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9846 removed.
9847 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9848 No need to remove the files before and after the each test, before
9849 each test and at the end of the suite is enough.
9850 Display only the children `times', not the shell's.
9851 If the test failed or was skipped, at-times is not available.
9853 2001-08-07 Akim Demaille <akim@epita.fr>
9855 Always produce testsuite.log, including when there are no
9856 failures. This helps getting information on skipped tests, and
9857 duration of the tests. Err, implement the latter btw.
9859 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9860 Dump information on the first run of each test.
9861 (AT_CLEANUP): Create `at-times' containing the duration of the
9862 test group.
9864 2001-08-07 Akim Demaille <akim@epita.fr>
9866 The use of `dumpstat' revealed that `len' was used although it
9867 should not. m4_text_wrap was using it, but in the Autoconf world
9868 where it is legal. Hence (i) test M4sh in its own world, not
9869 Autoconf's, and (ii), ahem, fix the bug :)
9871 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9872 does not like `' instead of [].
9873 (AT_INIT): Forbid `^_?AT_'.
9874 And don't output such tokens.
9875 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9876 `script.as', and `autom4te.cache'.
9877 Remove `empty' and `macro' which are no longer used.
9878 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.

9953 2001-08-04 Akim Demaille <akim@epita.fr>
